Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a wire-to-board connection assembly. Background Technology

[0002] A wire-to-board connector is an electronic component used to connect wires to a printed circuit board (PCB). It consists of two parts: a plug (connecting the cable) and a socket (mounted on the circuit board). It is an indispensable component in electronic devices. The plug is also called a wire connector, and the socket is called a board connector. Because electrical components need to be installed on the circuit board, in order to save space and improve space utilization, the electrical components are usually inevitably placed around the board connector. This results in a relatively cramped space around the board connector. Furthermore, since the installation angle of the wire connector is usually fixed, when the wire connector and the board connector are connected, the wire connector or the board connector may interfere with the electrical components on the circuit board. This affects the miniaturization design of the product and is not conducive to improving the product's space utilization.

[0003] Therefore, a wire-to-board connection assembly is needed to solve the above problems. Utility Model Content

Specifically, in this embodiment, the first clearance surface 131 and the second clearance surface 132 are both perpendicular to the third clearance surface 133, so that the opening of the first clearance space 13 faces the board end connector 20, thereby enabling the first clearance space 13 to provide a certain degree of protection for electrical components, thereby improving safety during use. The end of the wire end connector 11 away from the third clearance surface 133 is provided with a through groove for passing through the cable 15, which can ensure the installation stability of the cable 15 and thus improve the performance.
