倒で成形能率が悪かつた。(Prior art) There is a switch box in which a synthetic resin cover is attached to a synthetic resin base, and the cover is screwed to the base to securely fix the cover.In this type of switch box, a screw hole is formed in the base. Or,
Alternatively, nuts were inserted during base molding, but in the former case, the threads are made of synthetic resin, so if you tighten them a little too hard, the threads of the screw holes will break and tightening will become impossible. In addition, since the latter type uses a metal nut, there is no risk of damaging the thread even if the screw is tightened a little strongly, but inserting the nut etc. during molding is cumbersome and reduces molding efficiency. .

Reference numeral 1 denotes a base made of synthetic resin, and an engaging protrusion 2 having a substantially L-shaped cross section is formed at one end of the base 1, and a cross section with a notch 3 formed in the center is formed at the substantially center of the other end. A substantially U-shaped vertical wall 4 is formed, a tapered wedge-shaped projection 5 is protruded from the top toward the vertical wall 4 at a position corresponding to the notch 3 of the vertical wall 4, and an insertion hole 6 is provided approximately in the center. A vertical wall 7 is formed. 8 is a circuit breaker attached and fixed to base 1. Reference numeral 9 denotes a cover made of synthetic resin, and a rectangular hole 10 is formed approximately in the center of the lower part of one side of the cover 9, a U-shaped notch 11 is formed approximately in the center of the lower part of the other side, and the upper surface There is a window hole 12
is formed. A nut 13 is inserted and held between the corresponding vertical walls 4 and 7 of the base 1. 1
4 is a set screw for attaching and fixing the cover 9 to the base 1.
