ベース・カバーの締付装置の改良に関するもので
ある。[Detailed Description of the Invention] This invention relates to an improvement of a base/cover tightening device including, for example, a male screw for tightening the base and cover of a switch, and a female screw screwed thereto.

従来、この種の締付装置として第１図及び第２

通孔に嵌挿し更に雌ねじ２に螺着されてカバー３
を固定した雄ねじである。 Conventionally, this type of tightening device is shown in Figures 1 and 2.
I got what is shown in the figure. That is, 1 is a base made of a cast molded material, 2 is a female screw inserted into this base, 3 is a cover made of a cast molded material that is integrated with the base 1 to form a housing, and 4 is fitted into a through hole of this cover. The cover 3 is inserted and screwed onto the female screw 2.
It is a male screw that is fixed.

このような構成の締付装置は、雌ねじ２をベー
ス１の成形時にインサートするため、ベース１の
自動化成形が困難であると共に、例えば雌ねじ２
が破損した場合の取替えが不可能であるなどの欠
点を有していた。 In a tightening device having such a configuration, since the female thread 2 is inserted during molding of the base 1, automated molding of the base 1 is difficult.
It had the disadvantage that it was impossible to replace it if it was damaged.

この考案はこのような欠点をなくするためにな
されたもので、雌ねじを保持する構成部品をベー

とをなくしたベース・カバーの締付装置を提供し
ようとするものである。 This invention was made to eliminate these drawbacks, and aims to provide a base cover tightening device that eliminates the need to insert the female thread into the base by attaching the component that holds the female thread to the base. It is something.

次に、この考案の一実施例を第３図〜第７図に

同一につき説明を省略する。 That is, 5A is a rectangular through hole penetrated through the base 1, 5B is a step formed on one side of the through hole 5A, and 5C is a hexagonal bottomed hole formed at a predetermined depth from the other side of the through hole. , 5D is an extra wall formed at the boundary between the through hole 5A and the bottomed hole, and 6 is a bridge member, which includes first bent portions 6A formed in a U-shape and facing each other, and tongue-shaped third portions at both ends. It is composed of two bent parts 6B. 7 is a hexagonal female screw, 8A is a through hole that passes through the cover 3 and is continuous with the through hole 5A of the base 1;
B is a stepped portion formed on the surface side of the cover 3 of the through hole 8A. The other components are the same as those of the conventional one, and therefore their explanation will be omitted.

組立てが完了する。 Next, the assembly operation of the above-mentioned component parts will be explained. First, as shown in FIG. 4B, the female screw 7 is placed on the bottom of the U-shaped bridge member 6. Thereafter, when the bridge member 6 is manually pressed in the direction of arrow A, it is deformed as shown by the dashed line. In this state, insert the base 1 from the direction of the arrow B in FIG. Been the 5th
The configuration is shown in the figure. In this state, one surface of the female screw 7 is supported by the bottom surface of the bridge member 6, and the other surface is in contact with the extra wall portion 5D of the base 1, and the external shape fits into the internal shape of the bottomed hole 5C. It is configured so that it does not rotate. In this way, the cover 3 is placed on the upper plane of the base 1 in FIG. 5, and the male screw 4 is inserted into the through hole 8A of the cover 3, and FIG. 7 shows a state in which it is screwed onto the female screw 7. Assembly is complete.

以上のようにこの考案によればカバー取外しの
ため雄ねじを緩め雌ねじとの螺合を解除しても、
雌ねじは橋架部材により保持されているので脱落
することがなく、また雌ねじの取替えも至つて簡
単である。そしてまた、雌ねじはベースにインサ
ートされていないのでベースの自動化成形の作業
性が向上するなどの効果を有するものである。 As described above, according to this invention, even if the male screw is loosened and the female screw is unscrewed to remove the cover,
Since the female screw is held by the bridge member, it will not fall off, and replacement of the female screw is extremely easy. Furthermore, since the female thread is not inserted into the base, the workability of automated molding of the base is improved.
