あつた。Configuration of the conventional example and its problems A conventional example that is compared with the present invention will be explained with reference to FIGS. 3 and 4. In these figures, 1 is a conductive piece, 2 is a base made of synthetic resin, and 3 is a conductive eyelet. It has a cylindrical portion 5 with a small diameter d that can be inserted and caulked. In addition,
6 is a terminal portion. This eyelet 3 is constructed by connecting the conductive piece 1 with a stepped part of a large-diameter cylindrical part 4 and a caulked part of a small-diameter cylindrical part 5 in order to prevent poor contact between the conductive piece 1 and the eyelet 3 due to aging shrinkage of the base body 2. Although it is fixed by being inserted into the eyelet 3, the base of the small diameter cylindrical portion 5 is easily deformed by being pushed slightly downward due to the caulking of the eyelet 3, so that the contact between the conductive piece 1 and the eyelet 3 may be incomplete. It has the disadvantage of being easy to develop.

The electrical connecting device is constructed of a cylindrical part, and the crimping force when the cylindrical part is crimped is received by the rectangular cylindrical part partially in line with the cylindrical part.

The eyelet 9 has a rectangular tube portion 10 that is inserted into the base 8 and a diameter that is the same as the side length of the rectangular tube portion 10, and the conductive piece 7.
The cylindrical portion 11 is inserted into and caulked. That is, the side length D of the rectangular cylindrical portion 10 and the cylindrical portion 11
The diameters d of are equal. Note that 12 is a terminal portion.

There is no change in the effectiveness of the idea. In addition, in such a case, the cylindrical part may not be a perfect cylinder but may have a circular shape.

The base of the cylindrical portion is prevented from deforming, and the contact between the conductive piece and the eyelet is good, and there is no risk of contact failure due to aging shrinkage of the base, which is an excellent effect.
