1 is provided, and the insertion grooves 11 are connected by a convex surface portion 12 that has a thicker wall thickness at the center and becomes thinner toward the peripheral portion, that is, the insertion groove 11.
The contact terminal 13 attached to the contact terminal 13 is formed by bending a conductive metal piece into a substantially U-shape and having an intermediate piece 14 and both end pieces 15. A pair of inward facing pieces 16 are provided on both end pieces 15, and as shown in FIG. It is formed to be smaller than the maximum wall thickness M and larger than the minimum wall thickness m. Note that wiring connection legs 17 are provided at the tips of both end pieces 15 of the connection terminal 13. Convex portion 1
2 may be formed to have a trapezoidal or triangular cross section as shown in FIG.

付けられる。(Function) With this structure, as shown in FIG. Then, both ends of the intermediate piece 14 are bent, and as shown in FIG. It is attached elastically by the restoring force of the piece 14. In this way, the distance D of the contact terminal 13 only needs to be between the wall thicknesses M and m of the convex surface part 12, so strict dimensional accuracy is not required, and it can be manufactured at low cost. No rattling. Good elastic attachment.
