What are the main electrical characteristics of straight-through connectors?

I. How are the main electrical characteristics of straight-through connectors? The main electrical characteristics of straight-through connectors include contact resistance, insulation resistance, and electrical resistance. (1) An electrical connector with high contact resistance should have low and stable contact resistance. The contact resistance of a connector varies from a few milliohms to tens of milliohms. (2) Insulation resistance is a measure of the insulation between the contacts of an electrical connector and between the contacts and the shell, and ranges from a few hundred megohms to a few gigohms. (3) Electrical strength, or resistance to voltage and dielectric voltage, is the ability to withstand rated test voltages between the contacts of a connector or between the contacts and the shell. (4) Other electrical properties. Electromagnetic interference (EMI) leakage attenuation is to assess the shielding effect of the connector. Straight-through connector EMI leakage attenuation is to assess the shielding effect of the connector. It is usually tested in the frequency range of 100 MHz to 10 GHz. For RF coaxial connectors, there are also electrical specifications such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio (VSWR). With the development of digital technology, in order to connect and transmit high-speed digital pulse signals, a new type of connector appears, namely high-speed signal connector. Therefore, in terms of electrical performance, there are some new powers in addition to the characteristic impedance. Gas targets such as crosstalk (crosstalk), transmission delay (delay) and time delay (skew).
