Description

Technical Field

[0001] The utility model belongs to the field of electronics, and in particular relates to a connector socket. Background Art

[0002] A connector is also called a connector. It consists of a connector plug and a connector socket, and is used to connect two active devices to transmit current or signals. The connector socket is usually welded on a PCB board and plugged in and out with the connector plug. The traditional connector socket structure includes: a socket housing and wiring terminals arranged in the socket housing. The wiring terminals are usually needle-shaped and directly welded on the PCB board. The traditional connector structure is usually only suitable for the transmission of small currents. When used for large current transmission, the wiring terminals usually adopt a plug-in structure, which increases the plug-in and pull-out force between the connector plug and the connector socket. It is difficult for the PCB board to withstand such a large plug-in and pull-out force, which easily leads to breakage at the connection. In addition, it is inconvenient to directly weld the connector socket on the PCB board for disassembly and assembly. Utility Model Content
