In that case, only one of the pressing portion 3a and the locking portion 3b may be applied to the drag applying portion 2d. Although the processing of the locking spring 3 is not so easy as in the case of forming the, the contact connection between the electric wire 5 and the terminal plate 2 can be further stabilized.

A fifth embodiment of the present invention will be described below with reference to FIGS. 13 to 15. The members having substantially the same functions as those in the fourth embodiment are designated by the same reference numerals, and only different points from the fourth embodiment will be described.

In the fourth embodiment, the drag applying portion 2d is formed by partially cutting off the corner of the locking portion 3b of the locking spring 3 on the side of the central piece 2a.

It can be replaced and provided accordingly. In particular, in the second embodiment, since the drag applying portion 2d itself has elasticity, the electric wire 5 can be positioned more strongly between the drag applying portion 2d and the central piece 2a by fixing a member having large elasticity. Therefore, the contact connection between the electric wire 5 and the terminal board 2 can be made more stable.

Further, each structure in the first to sixth embodiments, that is, in the first embodiment, the drag applying portion 2d is formed by bending the facing piece 2b, the second embodiment. In the example, the drag applying portion 2d itself has elasticity, and in the third embodiment, the distance between the drag applying portion 2d and the center piece 2 becomes smaller as the distance from the wire insertion hole 1a increases, the fourth embodiment. In the fifth embodiment, the drag applying portion 2d is formed by cutting and removing a part of the locking spring 3, and in the sixth embodiment, a fastening portion 2g for fastening the locking spring 3 is provided.
