Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a housing unit for draw-out equipment such as a disconnector or the like which is housed in a distribution box.

<Prior art> This type of conventional housing unit has a rail, a drawer handle mounting bracket, a stopper, and a rail on a single steel plate.
Parts with specific functions such as interlock plates are attached by welding.

<Problems to be solved by the invention> However, in the conventional method, each part is attached by welding, which takes a long time to assemble, and has the drawbacks of poor dimensional accuracy and variation from product to product. Another drawback is that it is expensive because it has a large number of parts.

<Means for solving the problems> The present invention solves the difficulties of conventional devices, and provides a high-quality and economical housing unit that is compatible with the miniaturization and weight reduction of cutters and disconnectors in recent years. The purpose of this is to have a bottom plate made by bending both sides of a board with studs on the top, and a bottom plate that is placed closely on the top of this bottom plate to accommodate the necessary equipment for mounting drawer equipment. This is a technical means in which the rail, drawer handle attachment holder, stopper, interlock plate, etc. are constructed from two plates, including an auxiliary plate which is integrally formed from a single plate.

<Function> By providing the above means, all the predetermined functions are formed in one plate material, so it becomes unnecessary to weld and attach each part. In addition, the main parts are composed of only two plates, the bottom plate and the auxiliary plate, resulting in an extreme reduction in the number of parts.

<Example> An example of this invention will be described below with reference to the drawings.

The housing unit of this invention is broadly divided into a bottom plate 1 and an auxiliary plate 2. Studs 1-1 to 1-4 are implanted into the bottom plate 1 by welding. The auxiliary plate 2 has a drawer handle attachment holder 3, 4 for disconnecting a drawer device such as a wire cutter mounted thereon from the main circuit, stoppers 5, 6 for preventing over-insertion of the drawer device, and a drawer. Interlock plate 7 for device locking;
Furthermore, a rail 8 serves as a guide for inserting and pulling out the pull-out equipment.
9 is provided, and each of these parts is attached to one auxiliary plate 2.
It is formed by bending or cutting by pressing etc. 10 to 13 are studs 1 planted on the bottom plate 1
These are mounting holes corresponding to -1 to 1-4. In addition, 1
Bolts 4 and 15 are screwed into the stoppers 5 and 6 and fixed at predetermined positions.

As can be seen from the figure, the bottom plate 1 and the auxiliary plate 2 are combined by opening the mounting hole 10 of the auxiliary plate 2 from the top of the bottom plate 1.
- 13 are used to insert bolts into the studs 1-1 to 1-4, and the auxiliary plate 2 is closely placed on the upper surface of the bottom plate 1.

<Effects of the invention> As described above, according to the present invention, the rails necessary for mounting the drawer equipment, the receiver for attaching the drawer handle, the stopper, the interlock plate, etc. are integrally formed from a single plate material, which makes it possible to Compared to manufacturing each part individually and welding each part to the plate material, (1) the number of parts to be installed is drastically reduced, resulting in shorter assembly man-hours and lower cost.

(2) Since it is formed in one piece by press processing, there is no variation from product to product, and the quality is uniformly high.

In other words, no adjustment is required during assembly.

As mentioned above, the practical effects are very large in terms of cost and quality.

Claims (1)

[Claims for Utility Model Registration] A bottom plate formed by bending both sides of a board with studs on its top surface upward, and a bottom plate that is placed closely on the top surface of the bottom plate with both sides bent upward. There are two drawer handle mounting brackets that are bent at the front end, two stoppers that are bent at the rear end, and a rail that is bent at the front end. A housing unit for a drawer device, characterized in that it is constructed of two plates including an auxiliary plate formed integrally from a single plate with an interlock plate, etc. formed in a protruding position.
