Performance of waterproof connector
This article will mainly introduce the electrical performance of waterproof connectors and help those who do n’t know anything about the performance of waterproof connectors to better understand this product. The article will start from the contact resistance, insulation resistance and current of waterproof connectors. The four aspects of strength and electrical strength are explained one by one.
In general, the electrical performance of waterproof connectors is mainly manifested in four aspects: contact resistance, insulation resistance, current strength, and electrical strength. The specific content is as follows:
1. Contact resistance: High-quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to tens of milliohms.
2. Insulation resistance: A measure of the insulation performance between the contacts of an electrical connector and between the contacts and the housing.
3. Electrical strength or withstand voltage: The ability to withstand the rated test voltage between the contacts of the connector or between the contact and the housing, depends on the gap between the circuits (that is, the contact pitch and creepage distance) and the connector Insulation material.
4. Current: Limited by the electrical connector and its termination wires.
Other electrical performance and electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector, and it is usually tested in the frequency range of 100MHz ~ 10GHz.

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