ッチの強固確実な取付けを可能としたものである。[Detailed description of the invention] This invention relates to the improvement of indoor or outdoor switch boxes used in electrical wiring work.In particular, the invention relates to the improvement of indoor or outdoor switch boxes used in electrical wiring work. A plurality of reinforcing protrusions are provided inside the threaded groove, so that even though the lengths of various switches are different, they can be passed between the bottomed threaded hole and the bottomed threaded groove and screwed at the appropriate position. Moreover, even if a screw with a slightly larger diameter is inserted into the bottomed screw groove, the screw groove will not be pushed open, and the screw can be tapped and fixed securely, making it possible to install the switch firmly and securely. be.

この種の基台に長い螺着溝を設けるだけでは取付けねじ
を溝にねじ込むと弾力性により螺着溝が横方向へ押開か
れてタッピングが行われず、従ってスイッチ等の取付け
が強固確実にできない欠点があった。If only a long screw groove is provided on this type of base, when the mounting screw is screwed into the groove, the screw groove will be pushed open laterally due to its elasticity and tapping will not take place, making it impossible to firmly and securely mount switches, etc. There were drawbacks.

この考案は前記従来の欠点を解消したもので、以下これ

当する径）の多数の有底螺−着孔８を配列し、この有底
螺着孔８に対し取付けねじ７の螺軸よりや・幅狭（螺軸
の谷部に略相当する幅）で比較的長い有底螺着溝４を同
一配列とし、前記有底螺着溝４の内部にはこれと直角に
交叉する複数の補強用凸条５を一体形成する。This invention eliminates the above-mentioned conventional drawbacks, and will be explained below based on the drawings. In the drawings, reference numeral 1 denotes a base molded from thermoplastic synthetic resin, and a lid 2 is attached to the front surface of the base by a pivot 6. Installed freely to open and close, mounting panel surface 3 of the base 1
A large number of bottomed threaded holes 8 having a diameter slightly smaller than the threaded shaft of the mounting screw 7 (diameter approximately corresponding to the trough of the threaded shaft) are arranged in the bottomed threaded hole 8, and the mounting screw 7 is connected to the bottomed threaded hole 8. Bottomed screw grooves 4 that are slightly narrower than the screw shaft (width approximately corresponding to the trough of the screw shaft) and relatively long are arranged in the same manner, and inside the bottomed screw grooves 4 there are grooves that intersect at right angles thereto. A plurality of reinforcing protrusions 5 are integrally formed.

なお、この凸条５は実施例のように１区画に２〜３条設
けその断面形状を山形とすると取付けねじ７の溝４内へ
の誘導が的確に行える。If two or three of these protrusions 5 are provided in one section and have a chevron-shaped cross section as in the embodiment, the mounting screw 7 can be accurately guided into the groove 4.

又実施例では前記有底螺着孔８と有底螺着溝４とを交互
に設け、スイッチを上下にそれぞれ取付は可能としであ
る。Further, in the embodiment, the bottomed screw holes 8 and the bottomed screw grooves 4 are provided alternately, so that it is possible to mount the switch vertically.

この考案は前記のように構成したので、各種スイッチを
取付盤面に取着する場合、スイッチの長さ、大きさが若
干相違するも上部を螺着孔に合わせかつ下部は同一配列
の長い螺着溝の適宜位置でねじ止めすることができ、し
かもその有底螺着溝４に取付けねじ７をねじ込むとき、
補強用凸条５を複数設けたので長い螺着溝４が横方向へ
押開かれることがなく、取付けねじ７はタッピング作用
をともないながら的確に螺挿される。Since this invention is constructed as described above, when installing various switches on the mounting board surface, even if the switch length and size are slightly different, the upper part can be aligned with the screw hole, and the lower part can be installed with long screws in the same arrangement. The screw can be screwed at an appropriate position in the groove, and when the mounting screw 7 is screwed into the bottomed screw groove 4,
Since a plurality of reinforcing protrusions 5 are provided, the long screw groove 4 is not forced open laterally, and the mounting screw 7 is accurately screwed in with a tapping action.

而して基台１の取付盤面３にスイッチ等Ａがガタのない
よう強固確実に取付は得るものである。Thus, the switch etc. A can be firmly and reliably mounted on the mounting panel surface 3 of the base 1 without any looseness.

又基台１を熱可塑性合成樹脂製としたので、螺着溝４及
び凸条５は金型で一体成形できる。Furthermore, since the base 1 is made of thermoplastic synthetic resin, the screw groove 4 and the protruding strip 5 can be integrally molded with a mold.

従って強度的にもすぐれ、かつ均一な製品の量産が可能
となるため製品コストの低減を図ることができる。Therefore, it is possible to mass produce products with excellent strength and uniformity, thereby reducing product costs.
