Abstract

PURPOSE: To easily release the locking of an electric wire by combining a terminal main body, a terminal plate, a spring member, a pressing member, and a guide face in such a way that they can act on a specific work. CONSTITUTION: When an electric wire 5 is inserted in parallel to one side opposite piece 2b of a terminal plate 2 from the electric wire insertion hole 1a of a terminal main body 1, the electric wire 5 squeezes in a space between the one side opposite piece 2b of the terminal plate 2 and the tip end 3a of a locking piece 3c and also the rear end 3d of a spring member 3, so that the electric wire is brought into pressure contact toward the one side opposite piece 2b direction by the spring force of the tip end 3a of the locking piece 3c and the rear end 3d of the spring member 3 and at the same time, the tip end 3a of the locking piece 3c is brought into contact with the electric wire 5 at an acute angle to the pulling direction of the electric wire 5 so as to lock the electric wire and thus the electric wire is restricted from being pulled out. Then, in the case of pulling the electric wire 5 from the electric wire terminal, when a pressing member 4 moves, a face 4d moves to a deeper side from an inner storage part 1c. Due to the action of a lever, a ring in one end 4a, that is the tip end of the pressing member 4 in its moving direction, presses the locking piece 3c in direction reverse to the pressure contact direction and thus the locking of the electric wire 5 is released and the pulling out of the electric wire 5 is no more restricted and the electric wire 5 is pulled out from the electric wire insertion hole 1a.

Therefore, the work of pulling out the electric wire can be facilitated.

According to the eleventh aspect, in addition to the effect of the tenth aspect, a tool such as a screwdriver inserted in the communication space of the terminal body is brought into contact with a partition portion for partitioning the inner housing portion. By making contact with each other, the inner housing portion is not inserted, so that it is possible to prevent each member housed in the inner housing portion from being damaged by a tool.

According to the twelfth aspect, when a tool such as a driver inserted in the communication space of the terminal body reaches the tip of the convex portion along the inclined portion, the pressing member causes the tip guide portion facing the facing portion. Since it moves in the direction of the thickness of the convex portion by the thickness dimension of the convex portion, the same effect as that of the tenth aspect can be obtained without inserting a tool such as a screwdriver into the depth of the tenth aspect.

According to the thirteenth aspect of the present invention, the pressing member rotatably supported on the terminal main body by the supporting means has a tool such as a screwdriver inserted into the communication space. Since it can be easily rotated along the arcuate tip guide portion with a small force, it is possible to release the lock of the electric wire more easily than that of the tenth aspect.
