① high electrical contact resistance of the connector should have a low and stable contact resistance. Contact resistance of the connector from a few milliohms to tens of milliohms range. ② measure the insulation resistance between the insulation performance indicators electrical connector contacts and the contact member and the housing, on the order of hundreds to thousands of megohms megohm range. ③ said dielectric strength or resistance, voltage, medium voltage, tolerance is the ability to characterize the connector between contacts or contacts with the housing rated test voltage. ④ other electrical properties. EMI leakage attenuation of electromagnetic interference shielding effect of the evaluation of the connector, the leakage of electromagnetic interference attenuation of the connector is to evaluate the effect of electromagnetic interference shielding, generally in the frequency range of 100MHz ~ 10GHz test. RF coaxial connectors, as well as the characteristic impedance, insertion loss, reflection coefficient, voltage standing wave ratio (VSWR) and other electrical indicators. Since the development of digital technology electronic components connectors, in order to connect and transfer high-speed digital pulse signal, the emergence of new type of connector that is high-speed signal connector automotive wiring harness connector models, corresponding connectors good electrical properties, in addition to characteristic impedance, but also there are some new electrical connectors indicators, such as crosstalk (crosstalk), propagation delay (delay), Delay (skew) and so on. Connector also called connectors. The country also known as connectors and sockets, generally refers to the electrical connectors. I.e., the two active devices connected to the device, the transmission of current or signals. Connector brand Kana United States, New Zealand Trek, Toshiba, Molex and so on. Considering the connector technology development and the actual situation, its versatility and related technical standards, the connector can be divided into the following categories (sub-categories): ① low-round connector; ② rectangular connectors; ③ printed circuit connectors; ④ RF coaxial connector; ⑤ fiber optic connectors. 2.54 connectors, Xu Chong loose connectors, connector provided by Dongguan Shijie Song Chong-wook electronic products factory.
