The connector is also called connector (English connector). Also called connector and socket in our country, it usually refers to electrical connector. That is, a device that connects two active devices and transmits current or signals. The male terminal and the female terminal can transmit information or current after they are in contact, which is also called a connector. There are many types of connectors and various classification methods. A connector will have different naming methods according to different classification methods. If you do not understand the relevant knowledge, it is difficult to purchase. Now I will introduce you to the classification of connector types.
