Claims

[Claims for Utility Model Registration] In an RS232C cable connector in which a connector main body provided at both ends of the multi-core cable is provided with D-sub 25 pins for connection to each core wire of the multi-core cable, at least one A switch is provided between the soldered part of the connector pin located inside the connector body and one of the core wires, and the switch can be operated from outside the connector body to realize any or several specified connection methods. R, characterized in that it has a structure that allows the connection method to be switched.
Connector for S232C cable.
