According to the appearance: circular electrical connectors, rectangular electrical connectors. Circular electrical connectors are the most used in military equipment (aviation and aerospace). Rectangular electrical connectors are mostly used on printed circuit boards of electronic devices.
According to structure:
According to the connection method: threaded connection, bayonet (quick) connection, card lock connection, push-pull connection, direct plug-in connection, etc.;
According to the terminal connection form of the contact body: crimping, welding, winding; screw (cap) fixing;
Classified by environmental protection: environment-resistant electrical connectors and ordinary electrical connectors
According to the purpose: sealed electrical connectors, high temperature electrical connectors, separated electrical connectors, filter electrical connectors, power electrical connectors.
Among them, the connectors used inside the mobile phone include BTB connectors and FPC connectors. These connectors need to be tested before they can be used. The high-current shrapnel micro-needle module is used as the connection module to conduct current and transmit signals. effect. The high-current shrapnel micro-needle module can improve the test efficiency in the BTB/FPC connector test, the second is the long service life, and the third is that it does not produce any marks on the connector during the test, and the good rate can reach 90%. Above nine.
