The main electrical properties of the electrical performance connectors include contact resistance, insulation resistance and electrical strength.
1 Contact resistance High quality electrical connector (PTB14-5PSW (https://www.allicdata.com/product/connectors-interconnects/circular-connectors-adapters/ptb14-5psw/787278.html)) should have low and stable contact resistance. The contact resistance of the connectors ranges from a few milliohms to tens of milliohms.
2 Insulation resistance is an indicator of the insulation performance between the electrical connector contacts and between the contacts and the outer casing, which is on the order of hundreds of megaohms to several gigaohms.
3 Resistance to electric strength, or withstand voltage, dielectric withstand voltage, is the ability to characterize the rated test voltage between connector contacts or between contacts and housing.
4 other electrical properties. The electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector. The electromagnetic interference leakage attenuation is to evaluate the electromagnetic interference shielding effect of the connector, and is generally tested in the frequency range of 100 MHz to 10 GHz. For RF coaxial connectors, there are electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio. Due to the development of digital technology, in order to connect and transmit high-speed digital pulse signals, a new type of connector, namely high-speed signal connector, has appeared. Correspondingly, in addition to characteristic impedance, some new electrical indicators have appeared in electrical performance. Such as crosstalk, transmission delay, time lag, etc.
