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.

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 custom medical 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 military grade electrical connectors 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.
