Various board-to-board (B-to-B) connectors have been developed to solve space utilization problems due to the mounting of many components in a portable device. Such a board-to-board connector is configured to provide electrical or electronic control signals between components such as a power source, a computer, auxiliary hardware, or other electrical components within another electrical or electronic system.

These board-to-board connectors consist of a socket connector and a plug connector. It is important that the socket connector and the plug connector be firmly fixed to the circuit board and the board, and strongly support each socket body and the plug body.

In order to achieve a solid support and connection, a reinforcing member using a pair of metal fittings is integrally arranged on the side of the end wall of the socket connector and the plug connector. Such a reinforcing member can increase the self- And also serves to prevent cracks in the process of interconnecting the socket connector and the plug connector and to maintain the connection firmly.

Such a reinforcing member must be capable of being firmly engaged with the connector body so that it can serve as a desired fixing and supporting member while at the same time protecting the rigidity of the body and being firmly mounted on the circuit board. If these roles and functions are not satisfied, there may arise a problem that the reinforcing member easily separates from the connector molding, the injection-molded body by an external impact, or is easily separated from the circuit board. Further, when the socket connector is connected to the plug connector, there is a possibility that breakage or separation may be caused by friction or impact of the relative connector by the reinforcing member.
