Abstract: A connector housing composed of a block of an insulating material wherein a plurality of contact receiving holes penetrating from the front surface to the rear surface of said block are formed in at least one row and a slit is formed in the rear surface of the block to communicate said connector receiving holes with one another, whereby the connector housing can be used in common for a connector for wire connection and a connector for FFC connection.

Abstract: When a socket connector is inserted into an opening of a pin connector, a pin contact of the pin connector makes resilient contact with a socket contact of the socket connector to establish electrical connection therebetween. The pin connector has integrally therewith a connector locking member which is rotatable about an axis substantially perpendicular to the direction of insertion of the socket connector into the pin connector. The connector locking member has formed integrally therewith an engaging projecting which abuts against the rear end face of the socket connector when the connector locking member is turned for locking.
