In the connector device according to the first aspect of the present invention, the cord is formed by bundling a plurality of core wires, covering the core wires with the covering body, and holding the core wires in the cord accommodating holes of the plug with a predetermined gap. . When the male terminal on the plug connector side is pushed between the core wires of the cord held by the plug in this way, the core wire resists the elastic force of the flexible cover body and the cover body is housed in the cord. Expand the holes in the direction of the predetermined gap. Therefore, the male terminal of the plug connected body is electrically and surely connected to the core wire of the cord while being clamped by the elastic force of the covering body. Therefore, since the core wire of the cord does not require a terminal or the like for connecting to the male terminal as in the prior art, the structure is simple and the connecting work is easy.

According to a second aspect of the present invention, the tip portion of the cord is an exposed portion in which the core wire is not covered with a cover, and when the male terminal is pushed between the plurality of core wires, the core wire is not exposed. It easily spreads and acts as a guide for surely inserting the male terminal between the core wires.

According to a third aspect of the present invention, the plug is formed of a half-divided part which is integrated with each other by being fitted together, and the cord storage hole is formed with a retaining projection for pressing the cord, so that the cord storage hole has a predetermined gap. The cords that are held by the retaining projections are supported without slipping.
