They typically consist of a connector and a socket; the socket is contained within the circuit board, and the connector is mounted on an assembly that connects to the circuit board. If the connector is inserted perpendicularly to the circuit board, it increases installation space and size, and some connections may exhibit axial movement.

[0003] To address these issues, we developed a board-mounted connector. Utility Model Content
