Three categories of basic performance of connectors

1. Mechanical performance: The main plug-in force is divided into the plug-in force and the pull-out force, both of which will affect the reliability of the contact, the plug-in force of the connector and the machine

The mechanical life is related to the coating quality of the structural contact part of the contact and the dimensional accuracy of the arrangement of the contact.

2. Electrical properties: including contact resistance, insulation resistance and dielectric strength.

①The contact resistance of the connector ranges from several milliohms to tens of milliohms.

②The magnitude of insulation resistance ranges from hundreds of megohms to thousands of megohms.

③Electric strength is the ability to withstand the rated test voltage between the connector contacts or between the contacts and the shell.

3. Environmental performance: including temperature resistance, humidity resistance, salt spray resistance, vibration and impact resistance, etc.
