Electric performance parameters which contain the connector
< p > the main electrical connector performance including contact resistance, insulation resistance and electric strength. < / p > < p > (1) contact resistance < / p > < p > high quality electrical connectors should have low and stable contact resistance. The connector contact resistance range from a few milliohm to dozens of milliohm. < / p > < p > (2) insulation resistance < / p > < p > to measure electric connector socket connector between and contact between the shell and insulation performance indicators, the order of magnitude as megohm hundreds to thousands of ohms. < / p > < p > (3) the electric strength < / p > < p > the electric strength also called voltage, medium voltage, resistance is characterized connector contact or contact between the parts between the shell and the ability of tolerance test voltage rating. < / p > < p > (4) other electrical properties < / p > < p > leaked electromagnetic interference attenuation is connector evaluation effect of electromagnetic interference shielding, electromagnetic interference leaked attenuation is connector electromagnetic interference shielding effect, evaluation is in commonly 100 MHZ ~ 10 GHZ frequency range test. < / p > < p > for rf coaxial connector, and the characteristic impedance and insertion loss, reflection coefficient and electrical indicators such as voltage standing wave ratio. Due to the development of digital technology, in order to connect and transmit high speed digital pulse signal, a kind of new type of connector is high speed signal, accordingly, in terms of electrical performance, in addition to the characteristic impedance, also appeared some new electrical indicators, such as cross talk, propagation delay and delay. < / p >
