Electrical Performance of Connector

The main electrical properties of the connector include contact resistance, insulation resistance and electrical strength.

① Contact resistance High-quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector varies from a few milliohms to tens of milliohms.

② Insulation resistance is an indicator to measure the insulation performance between the contacts of the electrical connector and between the contacts and the shell, and its magnitude is in the order of hundreds of megohms to thousands of megohms.

③ The electric strength, or voltage resistance, dielectric pressure resistance, is the ability to withstand the rated test voltage between the contacts of the connector or between the contacts and the housing.

④ Other electrical properties. Electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector, generally tested in the frequency range of 100MHz ~ 10GHz.

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

Due to the development of digital technology, in order to connect and transmit high-speed digital pulse signals, a new type of connector has emerged, namely high-speed signal connectors. Correspondingly, in terms of electrical performance, in addition to characteristic impedance, some new electrical indicators have appeared, such as crosstalk, delay, skew, etc.
