HOW TO DETECT MEDICAL CONNECTORS

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.

 

  1. 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.

 

  1. Hot and cold shock test

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

 

  1. 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.

 

  1. 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.

 

  1. 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.

 

  1. 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.

 

  1. 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.

 

  1. Salt spray test

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

 

  1. 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.

 

  1. 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.

 

  1. Mixed gas corrosion test

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

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.
