Description

[Detailed Description of the Invention] The present invention relates to a cabinet for electrical equipment equipped with a resonance prevention device that can improve workability and reduce costs.

A conventional example is shown in FIG. 1 and FIG. 2.

Figure 1 is a longitudinal section, Figure 2 is a cross section, in which 1 is the cabinet lid, 2 is the cabinet body, 3 is a cushioning material such as Himeron or rubber, 4 is the inner surface of the cabinet lid, and 5 is the cushioning material 3. The end face of the cabinet body to be installed is shown.

Conventionally, the cushioning material 3 was adhered to the end surface 5 of the cabinet body 2 and fitted with the cabinet lid 1, and resonance, chatter, etc. occurring in the cabinet were prevented by contact between the inner surface 4 of the cabinet lid 1 and the cushioning material 3. .

However, this structure requires a large number of cushioning materials, making it expensive.Moreover, the installation of the cushioning materials requires bonding to small areas, which requires very difficult work and has the disadvantage of poor workability. there were.

The present invention relates to an electrical equipment cabinet equipped with a resonance prevention device that eliminates the drawbacks of the conventional cabinet, improves workability, and reduces costs.

The present invention will be explained based on the drawings.

FIG. 3 shows a longitudinal cross-sectional view of an electrical equipment cabinet provided with the resonance prevention device of the present invention, and FIG. 4 shows a cross-sectional plan view thereof.

The same reference numerals as in FIGS. 1 and 2 indicate the same parts.

In the figure, reference numeral 6 denotes an elastic rib formed integrally with the end surface 5 of the cabinet body 2 and having an inverted U shape.

This invention allows the cabinet lid 1 and main body 2 to fit together.
An elastic rib 6 integrally formed on the end surface 5 of the cabinet body 2 is in contact with the inner surface 4 of the cabinet lid 1, so that resonance, chatter, etc. occurring in the cabinet are absorbed by the elasticity of the rib 6. .

This invention is based on the above-mentioned structure. 1. It is possible to process the elastic ribs at the same time as processing the cabinet body, which eliminates the need for a separate cushioning material, reducing costs. 2. Work such as attaching and gluing the cushioning material. can be abolished, improving work efficiency.
It produces the following effects.

[Brief explanation of the drawing]

Figures 1 and 2 show an electrical equipment cabinet equipped with a conventional resonance prevention device. FIG. 4 shows a vertical cross-sectional view of the installed electrical equipment cabinet, and FIG. 4 also shows a cross-sectional plan view. 1: Cabinet lid, 2: Cabinet body, 4: Inside surface of cabinet lid, 5: End surface of cabinet body,
6: Ribs.

Claims (1)

[Scope of utility model registration request] In an electrical equipment cabinet in which an inverted box-shaped lid is fitted to a plate-shaped cabinet body and a resonance prevention device is provided between a contact portion between the two, an inverted U-shaped rib protrudes outward from an end surface of the cabinet body at the contact portion. A cabinet for electrical equipment in which a plurality of such components are provided on the peripheral side of the cabinet body and pressed against an inverted square-shaped lid to act as a resonance prevention device.
