Are accommodated, and the plug terminal 30 is electrically connected to a lead wire drawn out from the cord 21.

As shown in FIG. 14, a guide portion 4 for setting the insertion direction of the modular plug 2 is provided in a modular plug fitting hole 20 formed in the connector portion 23 of the modem card 1. The modular plug 2 can be inserted along the guide portion 4 from the inlet side 22 of the modular plug fitting hole 20 to the back side. As shown in FIG. Projection 27
However, by contacting the distal end position setting portion 5 of the modular plug fitting hole 20 as shown in FIG. 15 (b), the modular plug 2 is prevented from proceeding further.

A return preventing portion 6 is provided on the upper side of the entrance of the modular plug fitting hole 20 so as to prevent the inserted modular plug 2 from coming off and to lock the modular plug 2 into the modular plug fitting hole 20. And the projection 27 of the modular plug 2 fits into the modular plug fitting hole.
Immediately before coming into contact with the tip position setting portion 5 of the module 20, the rear end side of the hook portion 26 of the modular plug 2 is hooked on the return preventing portion 6, whereby the modular plug 2 is brought into the entrance side 22 of the modular plug fitting hole 20. It does not come back from the modular plug fitting hole 20.

When the modular plug 2 is to be removed from the modular plug fitting hole 20, as shown in FIG. It is pushed down with a finger or the like to approach the upper surface 15 side of the housing 24, and the hook portion 26 is removed from the return prevention portion 6 without being hooked.
