When it is inserted into the insertion hole 26 a formed in the terminal 26 and screwed into the screw hole 24 a of the terminal seat 24, the crimp terminal 21
Is clamped and connected to the terminal screw 25 and the terminal seat 24.

When the crimp terminal 22 of FIG. 6 is connected to the terminal 23 of FIG. 7, the terminal screw 25 screwed into the terminal seat 24 is slightly loosened, and the crimp terminal 22 is formed in the holding portion 27 with a notch forming portion. When the terminal screw 25 is screwed into the terminal seat 24 by inserting the terminal screw 25 into the screw portion 25a from the tip end to the base end of the terminal 27a, the crimping terminal 22 connects the holding portion 27 between the terminal screw 25 and the terminal seat 24. To be done.

[0005]

However, according to the above-mentioned conventional technique, in the case of the round crimp terminal 21 of FIG. 5, the terminal screw 25 must be removed once when connecting to the terminal 23, which is very troublesome. In addition to the work, there is a drawback that it takes time to work. Further, there is a drawback that the removed terminal screw 25 is dropped and lost.

Further, in the case of the Y-shaped crimp terminal 22 of FIG. 6, when the crimp terminal 22 is clamped and connected by the terminal screw 25 and the terminal seat 24, the crimp terminal 22 is a notch which is substantially the center of the clamp portion 27. Although the terminal screw 25 must be screwed at the base end of the forming portion 27a, the crimping terminal 22 has a tip from the base end of the notch forming portion 27a around the terminal screw 25 due to the rotational friction between the terminal screw 25 and the terminal seat 24. Since the terminal screw 25 is screwed to the tip of the notch forming portion 27a because it slides in the direction, the crimp terminal 22 is easily detached, which is dangerous, and the crimp terminal 22 is completely detached. There was a drawback that it was not connected to 23. Further, in order to eliminate these drawbacks, when the terminal screw 25 is screwed, the crimp terminal 22 must be supported by one hand so that the crimp terminal 22 does not slide, which is a very troublesome work. There was a drawback.

SUMMARY OF THE INVENTION An object of the present invention is to provide a crimp terminal which can be easily screwed onto the crimp terminal and can significantly reduce the working time.

[0008]

In order to solve the above problems, in the crimp terminal of the present invention, the holding portion is notched in a substantially Y shape, and a locking piece or a locking projection is provided in the vicinity of the tip of the notched portion. Is formed.

[0009]

[Operation] When connecting the crimp terminal to the terminal, loosen the terminal screw that is screwed into the terminal seat a little, and move the crimp terminal from the tip of the notch forming part formed in the holding part to the base end to the screw part of the terminal screw. When it is inserted and the terminal screw is screwed onto the terminal seat, the crimping terminal will slide from the base end of the notch forming part to the tip direction due to the rotational friction between the terminal screw and the terminal seat, and the crimp terminal will not come off the terminal. However, the locking piece or the locking projection formed near the tip of the holding part locks on the head of the terminal screw, and the crimp terminal is connected to the terminal screw at the base end of the notch forming part which is approximately the center of the holding part. It is clamped in the terminal seat and firmly connected.
