Description

{Case for installing electronic components}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic component case, and more particularly, to an electronic component case that shields electromagnetic waves and is easy to assemble.

2. Description of the Related Art An electronic device such as a digital video recorder (DVR) or a network video recorder (NVR) typically has a plurality of electronic parts mounted inside a case, A panel on which branch operating portions are arranged is located.

When the panel coupled with the case body of the electronic device is assembled separately using a material such as plastic, the appearance of the panel is brilliant, but is susceptible to electromagnetic interference (EMI) generated from the electronic device during operation, So that it is complicated in molding when engaged with the case body, and the strength of the fastening is weakened and the manufacturing cost is increased for fastening groove processing for fastening.

If the panel is not separately manufactured but is integrally manufactured with respect to the case body, the manufacturing process may be simplified, but a jig or the like is required to maintain the position of the case body for each post-processing such as a fastening groove on the panel, And the manufacturing tolerance increases.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the structure of a front panel coupled to a front surface of a case body and to provide an electronic component case in which the front panel can be easily assembled to the case body.

Another object of the present invention is to provide an electronic component case that shields electromagnetic interference using a front panel coupled to a front surface of a case body.

According to an aspect of the present invention, there is provided an electronic component case,

A case body having a space for accommodating the electronic parts therein,

And a front panel disposed on a front surface of the case body and coupled to the case body,

At least a part of the case body or the front panel is cut to form a hook,

And the other is a snap-fit structure having a coupling groove into which the hook portion can be inserted and fastened.

In one embodiment, the hook portion is formed on one surface of the front panel,

The fastening groove is formed on one surface of the case body corresponding to the hook portion when the front panel is engaged with the case body.

In one embodiment, the hook portion is formed by at least partially cutting one side bent portion bent from the edge of the front panel toward the case body, and is formed by being bent obliquely to the inside of the front panel,

The fastening groove is formed to be engaged with the hook portion on the corresponding surface of the case body.

In one embodiment, the hook portion includes a first portion that is incised in one direction at a central region of one bending portion of the front panel, a second portion that is cut at an interval therebetween, and a second portion that is formed by connecting the first portion and the second portion to each other And a third portion cut out from the front panel, wherein the cut portion is formed by bending the inside of the front panel.

In one embodiment, the hook portion is formed by cutting two portions at an interval along one direction from the edge of the front panel, and bending the cut portion to the inside of the front panel.

In one embodiment, at least one embossed portion is formed on one surface of the front panel,

The case body is formed with an embossed groove into which the embossed portion is inserted.

In one embodiment, the front panel includes a front panel flat plate, a plurality of short side bent portions bent from the edge of the front panel flat plate toward the case body, and a plurality of long side bent portions,

The respective short side bent portions and the respective long side bent portions are separated from each other.

In one embodiment, a plurality of wings extending from the bending portion along both ends are formed in any one of the short-side bent portion and the long-side bent portion, and the plurality of wings are folded in one direction.

In one embodiment, the front panel is made of a conductive material.

As described above, the electronic component case of the present invention can obtain the following effects.

First, since the front panel to the case body is manufactured in a snap-fit manner, space for screw tightening can be reduced.

Second, electromagnetic interference can be essentially shielded by manufacturing the front panel with a metallic material.

Third, since the front panel is made of a metallic material, the strength is reinforced, so that even if carelessness such as vibration or falling occurs, breakage can be prevented in advance.

Fourthly, since the front panel is manufactured separately from the case body, post-processing of the front panel such as the formation of the fastening groove and the painting process is easy.

Fifth, since the front panel can be manufactured by press working, the manufacturing process is simplified and the manufacturing cost is reduced.
