In the past, the application of electronic modules to automobiles was relatively simple. Today, a new form of technology is emerging. Vehicle systems are connected to sophisticated electronic devices that drive modularity. With the increase in cabin systems, human-machine interfaces, radars, and cameras, the number of multi-interface printed circuit boards (PCBs) and flexible components is also increasing. These components require connector products to enhance signal integrity and ensure transmission speeds in harsh environments.

The latest trend in the market is the integration of connected sensors, and the need for interconnection has created huge business opportunities for suppliers.

Trend 1: Human Machine Interface (HMI) connection

More and more applications use interfaces for communication, and most user interfaces have flexible board-to-board (F-to-B) connection points that require flexible printed circuit boards or board-to-board connectors.

The demand for sensors, microphones, speakers, and cameras is driving increased modularity, which requires more and better flexible printed circuits (FPCs), flexible flat cables (FFCs), board-to-board, and wire-to-board signal connections.

Trend 2: Durability requirements for harsh environments

Flexible components and printed circuit boards are becoming more complex. Harsh environments require higher signal integrity and more stable retention characteristics to withstand shocks and vibrations, which requires more and better flexible printed circuits (FPC), flexible flat cables (FFC), board-to-board and wires Signal connection to the board.

Consider the need for high-performance, durable interconnects early in the development process.

Trend 3: Limited space requires design flexibility

Automotive applications are getting smaller and smaller. The increased modularity limits the space between the connector and other components, requiring more space-matched miniature connector products.

Miniature connectors with multiple contact surfaces and orientations address the design challenges presented by designers with space, location, and connector entry points.

Vehicle electronics now require higher speeds and signal integrity to transmit higher bit-rate data streams.

The key to success in this area is a high-speed solution that supports the signal integrity (SI) required for sensor, camera, human-machine interface, and system communication.

D-sub connectors are bulky and durable, which made them suitable for being applied in harsh environments where durability is extremely important. They can also be compatible with many old-fashioned devices. For these advantages, D-sub is widely used in factories, manufacturing workshops and industrial environments.

Medical connectors are connector products used in the medical field. The product quality of medical connectors should be strictly checked, and it is the responsibility of each factory to do the testing of medical connectors.

The detection method of medical connectors is basically the same as that of ordinary connectors, mainly involving twelve aspects:

1. Plug-in force test

Fully insert or pull out the connector at the specified rate, and record the corresponding force value.

Check whether the insertion force of the medical connector meets product specifications.

2. Durability test

Continue to insert and remove the connector at the specified rate until the specified number of times.

Detect the impact of repeated insertion and removal on medical connectors, and simulate the insertion and removal of connectors in actual use.

3. Hot and cold shock test

Evaluate the impact value of the connector on its functional quality under rapid large-scale changes.

4. Withstand voltage test

Apply a specified voltage between the connector contact and the contact, and between the contact and the housing for a specified time, and observe whether the sample has a breakdown or discharge phenomenon.

Verify whether the connector can work safely at the rated voltage and whether it can withstand the potential of overpotential, so as to assess whether the insulation material or insulation gap of the connector is appropriate.

5. Contact resistance test

By passing a prescribed current to the connector, the voltage drop across the connector is measured to obtain the resistance value.

Verify the resistance value generated when current flows through the contact surface of the contact.

6. Vibration test

Verify the impact of vibration on the performance of the electrical connector and its components. The types of vibration are random vibration and sinusoidal vibration.

7. Mechanical shock test

Verify the impact resistance of the connector and its components or assess whether its structure is firm. Test waveforms: half-sine wave, square wave.

8. Insulation resistance test

A voltage is applied to the insulated part of the connector, so that a leakage current is generated on the surface or inside of the insulated part to show the resistance.

Verify whether the insulation performance of the connector meets the requirements of the circuit design or is subjected to environmental stress such as high temperature and humidity, and whether its resistance value meets the requirements of the relevant technical conditions.

9. Salt spray test

Evaluate the resistance of connectors, terminals, and coatings to corrosion by salt spray.

10. High temperature test

Evaluate whether the performance of the terminal and insulator changes after the connector is exposed to a high temperature environment for a specified period of time.

11. Temperature and humidity combined cycle test

Evaluate the impact of the connector on the performance of the connector after storage in a high temperature and high humidity environment.

12. Mixed gas corrosion test

Evaluate the corrosion resistance of connectors exposed to different concentrations of mixed gases and the impact on their performance.

D-sub connectors are bulky and durable, which made them suitable for being applied in harsh environments where durability is extremely important. They can also be compatible with many old-fashioned devices. For these advantages, D-sub is widely used in factories, manufacturing workshops and industrial environments.

The key factors for determining signal connectors in industrial applications include: cost, environment, vibration, connector density, signal integrity, installation method, and safety requirements.

Where are the signal transmissions in industrial and semi-industrial environments? Everywhere. Devices such as sensors, actuators, switches, valves, and cameras all require signal connections to perform control and monitoring processes. As more and more smart devices are added to factory production, safe and reliable connections become more important. Modern devices must handle a variety of functions and ensure more efficient, reliable, and safe operation.

The environment around the signal connection often affects the reliability of the signal. These factors include: dirt, moisture, oils, chemicals, high and low temperatures, and ultraviolet and ozone, which must be considered in the selection of materials and sealing capabilities. In addition, electromagnetic interference (EMI) from nearby drives, motors, and other noise-generating equipment should also be considered. Without proper shielding, signal loss or unreliable signal transmission may result. Using connectors and cables to provide end-to-end signal shielding will eliminate electromagnetic interference and ensure signal integrity.

Many connections in industrial applications are exposed to mechanical shock and vibration. This impact on connector contacts, wire ends, or PCB solder joints can cause signal loss. When selecting connections for high-strength vibration applications, it is necessary to verify the connector design of anti-vibration structural elements, such as: locking threads or mechanical latches, radial O-rings, mounting flanges, fixing screws and spring technology.

Every application requires a reliable connection, and signal integrity may be destroyed by any breakpoints along the line. In addition to the wire end to the contact, the quality of the contact material is the most important factor affecting performance. When evaluating contact designs, the use of gold plating should be determined. Gold is a precious metal with good electrical properties and is not affected by corrosion. Preventing contact corrosion and having a high mating contact force are two key reasons for using gold plating in industrial applications.

Quick connection is also necessary for equipment installation, especially when the job requires a large number of connections. The shortest installation time can reduce the total cost. The connection is usually located in an inconvenient area or in a place with poor lighting. Finger fatigue and incorrect fastening will affect the success of rapid installation. By designing quick connection devices, such as spring cages or insulation displacement contacts (IDCS), at the PCB end, some of these problems can be prevented. On site, these devices provide quick plug connections, including half-turn technology or push-pull connections. When the equipment connection requires on-site wiring, the use of external connection, IDC or spring connection can save a lot of time. Because these technologies can achieve more connections in a shorter time. Research has proved that some IDC connectors can save 60% of the installation time. Compared with traditional screw joints, spring contact connectors can save 80% of the time.

Eliminating potential connection errors is a major concern for end users and field technicians, but equipment manufacturers and engineers can prevent potential erroneous connection factors during the design phase. When multiple connectors in the same space are used in a device, connector keying can eliminate confusion and effectively prevent users from inserting the wrong connector into the wrong socket. For example, in a typical signal connection scheme, engineers can select circular connectors with keyed changes, including: A, B, C, D, S, T, X, or Y. The terminal module connector can also be keyed in several modes to ensure that only the correct plug can be matched with the appropriate socket.

Marking and color coding can also reduce false matches. The most common mistakes made by technicians in the field are misconnections. Incorrect line terminals and incorrect terminal assignments may delay system commissioning and equipment startup. The use of color coding or other indicator marks on all line connection points can eliminate confusion and reduce the time spent troubleshooting on site.

When selecting signal connections for industrial applications, many variables that affect performance must be evaluated, including: cost, environment, vibration, connector density, signal integrity, installation method, and safety requirements. High-quality industrial connectors will help to ensure that terminal devices comply with international standards and provide safe and durable performance.

INDUSTRY & SOLUTION

Sunkye is a global solutions provider of connector solutions and differentiated products to the world-wide interconnector industry.

For some industries, the waterproof connector is very necessary, so that it can protect the safety of the product, and it is also a guarantee for personal safety.

How to prefabricate cables for waterproof connectors?

XLPE insulated cables above 110kV level mainly use metal sheath to make the cables meet the waterproof requirements. The biggest feature of the metal sheath is that it is completely impermeable, so the cable with a metal sheath has very good radial water resistance. The main types of metal sheath are: hot-pressed aluminum sleeve, hot-pressed lead sleeve, welded wrinkled aluminum sleeve, welded wrinkled steel sleeve, cold drawn metal sleeve, etc.

The power cable can provide the input power for the waterproof connector system. This power supply uses the traditional wiring method, or a standard waterproof plug is installed on the power supply end, and a required socket connector can be prefabricated on the other side.

The extension cable needs to be installed with an inner socket or plug at the end of the relevant cable, and the wiring cable needs to be equipped with a plug and a bare wire end for the waterproof plug to connect the final device.

Breakout connector: The waterproof plug can be pre-installed on site to provide direct wiring for electrical user devices. All waterproof connectors are delivered with a stress-reduced housing and are compatible with all common types of cables. According to the requirements, the waterproof plug has a spring or screw connection technology.

Sunkye is a professional ip68 waterproof power cable connector manufacturer and supplier, who support custom connectors for a complete range of high-performance applications. A wide variety of military connector options are available to you, feel free to contact us.

The Sunkye connection forms of industrial electrical connectors can be roughly divided into four types, and more types are currently used. Here are four of them:

Threaded connection
Some types of connections are commonly used for contacts with larger dimensions and electrical connectors that operate in high vibration environments. This type of connection can be equipped with a fuse to prevent loosening after the connection is completed. The connection is reliable, but the connection is slow.

Bayonet connection
This is a reliable and fast form of connection and disconnection. Most electrical connectors in the form of a card 121 connection have a visual display of proper connection and locking, and can be seen through a small hole on the side of the electrical connector's connection nut.

In-line connector
This is a versatile form of connection. When the plug and socket of the electrical connector are connected and disconnected, the moving direction is usually a reciprocating linear motion, without twisting and rotating, and only requires a small working space to complete the loading and unloading. Common plug-in connections come in spherical or pin configurations. Because there is no mechanical labor-saving mechanism in the connection form, once it is inserted incorrectly, the mechanical resistance increases significantly and can be found in time.

Electrical connector cabinet connection
This is an electrical connector used on some devices and requires a blind connection near the frame. It can make electrical equipment lighter, smaller, easier to maintain and more reliable.

This type of connection prevents the operator from feeling the connection. It is necessary to design an accurate positioning device to avoid forcibly connecting the wrongly inserted electrical connectors together, so that the wrong insertion cannot be performed. Cabinet-type electrical connectors are usually designed with floating or resilient contacts to ensure proper connection.

First, conceptual difference between connector and terminal

1. Connector. It is a component often contacted by electronic engineering technicians. Generally refers to electrical connectors. That is, a device that connects two active devices and transmits current or signals.

Sunkye Connector also refers to a positioning connector for connecting electronic circuits, which is composed of two parts, namely the plug-in and the connector, which can be completely separated in general. The difference between a switch and a connector is that the change of the contact state of the contact pair achieves the conversion purpose of the connected circuit, and the essential difference is that the connector has only two states: insertion and removal. The switch can realize the conversion of the circuit on the body, but the connector cannot achieve the conversion on the body, and there is a fixed correspondence relationship between the contact pairs of the connector.

2. Terminal. It is an accessory product used to achieve electrical connection, which is industrially divided into the category of connectors. The terminal is used to facilitate the connection of the wires. It is actually a piece of metal sheet enclosed in an insulating plastic. There are holes at both ends to insert the wires. Terminals can be divided into WUK terminals, European terminal series, plug-in terminals, and so on.

Second, the difference between the scopes of the connector and the terminal

1. "Connector" is the first category, and the terminal is just one of the "connector" category. A connector is a wire-to-wire connection; a connector is a wire-to-board and box connection. It is often classified into one category in practical applications.

2. The terminal is part of the connector. Connector is a general term. In fact, the connectors we commonly see usually include housing and terminal. The housing is mostly plastic, which plays a protective role, and the terminal is a metal, which plays a conductive role.

3. Connectors and terminals in the electrical and electrical fields:

A connector is commonly understood as a kind of thing that can be quickly connected with a single plug or twist without using tools.

Terminal, in plain understanding, is the kind of thing that requires tools, such as screwdrivers and cold press pliers, to connect two things together, and is generally used for power input and output.

Third, the difference between the practical applications of the connector and the terminal

Connectors are a subdivided field of electronic components, mainly used for the connection between circuits. In industrial production, line connections can be said to be ubiquitous, so the range of use of connectors is of course very wide and is used in various industries.

Connectors are divided into many categories, such as rectangular connectors,circular connectors,stepped connectors, and so on. The terminal is a type of connector, which generally belongs to rectangular connectors. The use range of terminal strips is also relatively single. It is generally used in the field of electronics and electronics, and is used for internal and external wiring of PCB circuit boards, printed boards and power distribution cabinets.

The range of use of terminal is increasing, and the types are increasing. At present, in addition to PCB board terminals, the most widely used are hardware terminals, nut terminals, spring terminals, etc. In the power industry, there are special terminal strips, terminal boxes with various terminals, such as single-layer terminal, double-layer terminal, current terminal, voltage terminal, common terminal, breakable terminal, etc.

In general, "connectors" and "terminals" are different application expressions that belong to the same concept, and are named according to different actual applications.

The strip connector generally realizes the connection between the printed board and the printed board, cooperates with the socket to complete the connection of the board and the cable (burning program), and cooperates with the circuit breaker to complete the board jumper function.

1.Classification of strip connectors(space grade connectors)

Sort by spacing

2.54mm, 2.00mm, 1.27mm, etc.

Classification by termination

Through hole (THT), surface mount (SMT), straight pin, curved pin

Classified by shape

Single-layer type, double-layer stack type, through-wall type.

2.Notes on selection of strip connectors

The non-contact parts (pins, transition areas) are tin-plated, and the contact parts are gold-plated.

Selection of gold plating thickness for contacts: 0.25um plating thickness is preferred for common applications, 0.76um is preferred for more frequent mating applications.

A 2.54mm pitch is recommended, and a 2.00mm pitch is required when space is critical.

It is recommended that the working current of each pair of pinholes does not exceed 3A.

Pay attention to the insertion depth of the hole seat when selecting the model to ensure a reliable fit (more than two-thirds of the depth of the plastic body).

According to the product structure height requirements, choose the corresponding height of the needle seat, hole seat. When the distance between the boards is less than 11mm, ordinary pins and sockets are used. Stacked pin holders above 11mm are used with ordinary hole seats (the maximum board spacing can reach 34mm).

Recommended surface mount form for pitches below 2.00mm.

The needle hub is preferably 40 needles.

Looking for micro d connectors manufacturers?Sunkye is uniquely qualified to deliver turnkey custom solutions and Mil-Spec military connectors manufacturer for a complete range of high-performance applications. Our industry-leading materials knowledge, engineering design experience, and testing capabilities are key to achieving reliable service in the most extreme environments.

1.Avionics Connectors Mechanical parameters made by Sunkye

Mating force

Insertion force is an important mechanical property for measuring connector performance. The insertion force is divided into insertion force and extraction force, and the requirements of the two are different. From the use point of view, the smaller the insertion force, the better, but the extraction force should not be too small, otherwise it will affect the reliability of the contact.

Mechanical life

Mechanical life is actually a kind of durability index. It is based on one insertion and one extraction as a cycle, and judges whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle. .

It is related to the structure of the contact (positive pressure), the quality of the coating at the contact site (coefficient of sliding friction), and the accuracy (alignment) of the size of the contact arrangement.

2.Electrical parameters

Contact resistance

High-quality electrical connectors should have low and stable contact resistance. The contact resistance of a connector ranges from a few milliohms to tens of milliohms.

Rated current

Depending on the material and cross-sectional area of the terminal, the larger the cross section, the smaller the resistance per unit length, and the less heat generated by the current flow, the smaller the temperature rise of the terminal, and the larger the current can be conducted.

Dielectric strength

The index for measuring the insulation performance between the contacts of the electrical connector and between the contacts and the housing, the order of magnitude is from several hundred megohms to several gigaohms.

Dielectric strength

Also called withstand voltage, dielectric withstand voltage, is the ability to withstand the rated test voltage between the contacts of the connector or between the contact and the housing.

Other electrical parameters

Electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector, and it is generally tested in the frequency range of 100MHZ to 10GHZ.

For RF coaxial connectors, there are also electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio.

3.Environmental parameters

Temperature resistance

At present, the maximum working temperature of the connector is 200 ° C, and the minimum temperature is -65 ° C. ——Temperature resistance test, temperature cycle test

Resistance to moisture and moisture

The intrusion of moisture will affect the insulation performance of the connector and rust metal parts. ——Constant Damp Heat Test, Alternate Damp Heat Test

Resistant to salt spray

The connector works in an environment containing moisture and salt. The metal structure and contact surface treatment layer may cause galvanic corrosion, which affects the physical and electrical properties of the connector. ——Salt spray test, corrosive gas test

Resistant to vibration and shock

Vibration resistance and shock resistance are important properties of electrical connectors. They are particularly important in special application environments such as aerospace and railways. It is an important indicator of the robustness and electrical contact reliability of the mechanical structure of connectors. ——Vibration test, physical shock test

From the purpose of using automotive connectors,in order to ensure better driving of the car, Sunkye can divide the reliability of the connector into the tightness of the connector in use, the performance of fire protection, the performance of shielding, and the performance of temperature control.

Generally speaking, when discussing the tightness of automotive connectors, it does not only refer to the tightness to water. In this area, the current popular international management specification is IP67, and this specification is now the highest level in the automotive industry. Although the requirements for waterproofing are different in different parts of the car, many car manufacturers will choose IP67 to ensure the tightness of the connector of their car.

In the driving of a car, the power source is a very important energy source, which is not only related to the normal work of the engine, but also often involves the use of the power source when people are driving. So in the car's power supply system, car connectors have different divisions. Certain sealing measures can be implemented between the male connector and the device, between the male connector and the cable, between the male and female connector, and between the female connector and the cable.

In the realization of the sealing performance of automotive connectors, the seal ring is a commonly used tool. This tool can not only achieve the effect of fixing between different hole positions, but also the effect of sealing. It can not only ensure the stable operation of automobile equipment, but also ensure the waterproof performance of automobile equipment in work.

In the production of seal rings, silicon rubber is mostly used. This material is made by liquid silicon and solid silicon after certain chemical changes.

Now that electronic circuit technology is an important aspect of the automotive industry. In order to ensure the stable operation of electronic circuit technology, people have applied many shielding technologies in the production of automobiles. These shielding technologies not only play a protective role in the electronic circuit of the car, but also play a role in anti-interference and anti-radiation in the parts of the car. In addition, they can also protect the stable operation of the automotive connector.

Shielding technology can be divided into two types: internal shielding and external shielding. When using an external shield to protect a car connector, two identical shield shells are usually assembled to form a shield layer, and the length of the shield layer can cover the entire connector length. It is also necessary to ensure that the shield shell There are enough lock plate structures to ensure the reliable installation of the shielding layer. In addition, the shielding material used must not only be treated by electroplating, but also be treated to prevent chemical corrosion.

For the connector industry practitioners, military connectors should not be unfamiliar. We've all heard of military style connectors. Do you know how the function of military connectors works? The function of connectors in production is the function of connections. But in other industries, what relevant functions will military connectors play? Let's talk about this.

In the maintenance industry, especially in the automobile maintenance industry, the use of military style connectors will bring us a lot of help. In the process of maintenance, after using the connector, there is no need to worry about the other operation of the machine, and no need to worry about the other parts of the car stopping because of the repair.

Another function of connectors is that when military connectors are used, they will have different shape design requirements. Each type of connector will have its own application requirements. Of course, in actual use, we can also choose to use some connectors with shape requirements.

Military style connectors will always have different applications in different industries, but in the process of application are different, the main role of connectors in the production process is to connect different production parts. Military connectors play a simple connection role.

Sunkye is a manufacturer specializing in mil grade connector, connector design and production, devoted to connector design and development for more than ten years. It strives to become a leader in the industry, providing customers with competitive solutions and products.

Electrical connectors are key devices that join electrical circuits, equipment, terminal, and application together. Most connectors are removable (a pair with plug and socket) or temporary(removable contacts, pogo pin, insulator, backshell, and shell), but some can be permanent (Sunkye twist pin connector). Connectors make electronic products easier to assemble and manufacture. They also ease circuit repairs and allow flexibility in design and modification. They are used extensively on circuits for communications, industrial machinery, railway, defense system, landing radar, UAV, sensor system, and special field. Sunkye is uniquely qualified to deliver turnkey custom solutions with a complete range of High-Pressure, High-Temperature HPHT electrical connectors.

There are many kinds of micro miniature coaxial connectors: SMA, SMB, SMC, APC-7, K connector, etc. This article will give you an interpretation.

Whatever connector you use, you need to pay attention to its applicable frequency range before using it. The frequency range of the connector is limited by the first circular waveguide propagation mode in the coaxial structure. Reducing the diameter of the outer conductor will increase the maximum usable frequency. Filling the space with insulators reduces the maximum usable frequency and increases system losses. The performance of all connectors is affected by the quality of the connector interface. If the diameter of inner and outer conductors deviates from the design requirements, the quality of electroplating is poor, or the gap between the joints is large, the reflection coefficient and resistance loss of the interface will be reduced. This is why in the same kind of connector, the one with good quality, can be used at higher frequencies and has smaller standing wave coefficients.

If the circuit you need to measure and test is below 18GHz, you can choose SMA connector, N connector and APC-7 connector. You can choose the specific type, according to your circuit type, cost and so on. If you have enough money, you can also use K connector, etc. If you measure and test in millimeter wave band, you can choose K connector or 2.4mm connector. Why not choose a 3.5mm connector? Because compared with K-connector, it has neither price advantage nor performance advantage (the applicable frequency is not as high as K-connector).

With the increasing demand for high-density connectors in the medical market, the irreversible trend of connectors in the medical field is becoming smaller, lighter and more ergonomic. This trend strongly drives demand growth.

High density connectors are connectors with large numbers of individual contacts such as PIN pins in a relatively small connector body. There is no clear boundary between standard connectors and high density connectors, but the designation of high-density connectors is usually defined by having more contact points in the same shell size.

The growth demand for high density electrical connectors is driven by many factors, especially the size, weight and function requirements. Component size and weight have long been a key factor in many military and aerospace applications. With the increasing popularity of portable and patient wearable devices, connectors are becoming more and more important in the medical market.

In order to meet the growing demand of the higher density connector market, many manufacturers are developing standard and ready-made high density connectors solutions. When connectors need to meet a specific application and the output is limited, this solution is effective and feasible.

However, the development of standard high-density connector products will be targeted. Connector manufacturers must consider a variety of characteristics when developing to meet a wide range of application needs and budget constraints. Mature connector manufacturers with industry-leading ideas can successfully use this strategy, but this strategy is not universal.

High density connectors will continue to develop, and the trend of products will be towards miniaturization, high precision and hybrid functions. With the gradual realization of these product technologies. Engineers will surely develop new connection technologies to further improve contact density, size, weight, performance and function, and to further ensure product reliability and safety. Standards and customized solutions will greatly meet the growing demand for high-density electrical connectors in the medical market.

Aerospace UAV Connectors are an important basic component that is almost ubiquitous in military and aerospace aircraft & UAV applications and serve as interconnects for transmission signals and power, which has to meet stringent testing for outgassing and residual magnetism to be suitable for use in airspace & UAV applications. Outgassing and residual magnetism can adversely affect nearby components. 

Weight & space saving is necessary for Aircraft & UAV connectors because there is only so much room on a space vehicle. They have to be extremely reliable as well and they must resistant to severe environmental conditions like shock, radiation, extreme temperatures, and vibration.
