Description

[Detailed description of the invention] The invention has a mounting part for a heat sink and a printed wiring board,
This relates to a chassis device that constitutes, for example, a television receiver, along with a front panel and a cabinet, and the purpose is to simplify the configuration itself and reduce assembly man-hours and component costs.

Conventional devices of this type consist of a front mounting part for mounting front operating parts and a chassis parts mounting part integrally constructed using metal fittings.
When attaching to the front panel of an electronic device, it is attached with screws, or the front attachment section is separated from the chassis component attachment section and each is constructed with metal fittings or molded parts, while the front attachment section is attached to the front panel of the device with screws. was.

However, in the case of the above conventional method, the structure of the chassis itself must be made strong, and mounting parts such as screws are required to attach the front mounting part to the front panel of the device, resulting in problems in terms of workability and cost. there were.

The present invention eliminates the above-mentioned conventional drawbacks.

One embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a chassis device according to an embodiment of the present invention.
Figure 2 shows a side cross-sectional view of the chassis device assembled into the front panel of the equipment (in this case television 1) and covered with the equipment cabinet, and Figure 3 shows the chassis component fittings fitted into the equipment cabinet chassis. Each shows a partial plan cross-sectional view in a state where it is fitted into the joint rib.

As shown in Figures 1 and 2, 1 is the front mounting part of the device (
For example, the front mounting part 1 has a plurality of fittings each having a tapered hole on the inner surface. A joint cylinder 1a is provided.

Reference numeral 2 denotes a chassis component mounting portion integral with the front mounting portion 1, which forms a holding groove 2b into which chassis component fittings (for example, a heat sink 1 holding portion 2a and a printed wiring board 4 are inserted and held).

Reference numeral 3 denotes a chassis component, which includes a through hole 3a, and a plurality of fine holes 3b formed at regular intervals, each of which is formed continuously with the through hole 3a and has a width of one width than the through hole 3a.

In the above configuration, in order to attach the chassis component fitting 3 to the chassis component mounting part 2, the L-shaped chassis component holding part 2 is inserted into the through hole 3a drilled in the chassis component fitting 3.
a, push the metal fitting 3 in the direction of arrow A in FIG.
Slide the metal fitting 3 in the direction of arrow B in Figure 1.
When the holding part 2a is pushed in at position 1 where the front edge 3' of the front mounting part 1 contacts the back wall 1' of the front mounting part 1, the holding part 2a comes into contact with the metal fitting side wall at the upper part of the small hole part 3b and prevents the metal fitting 3 from falling off. 3 is held by the chassis component mounting portion 2.

On the other hand, the printed wiring board 4 is inserted into the holding groove 2b of the chassis component mounting portion 2 in the direction of arrow C in FIG.

In order to attach the chassis body with all the chassis components attached as described above to the front panel 5 of the device, as shown in FIG.
Align the position of a and the fitting tube 1a provided on the front mounting part 1,
The fitting boss 5a is pushed in by sliding it on the inner wall of the fitting cylinder 1a.

The inner wall of the fitting cylinder 1a is tapered, so when pushed in at a certain position, the gap between the fitting boss 5a and the fitting cylinder 1a disappears, the fitting becomes tight, and the chassis body is removed from the front panel 5. It is held without falling off easily.

When the equipment cabinet 6 is covered in such a state, as shown in FIGS. 2 and 3, the cabinet 6
The chassis fitting rib 6a is the rear edge 3 of the chassis component fitting 3.
Hold the chassis component fittings 3 by pressing them in the direction of the front mounting portion 1.

Therefore, the rear edge 3' of the chassis component fitting 3 is pushed by the chassis fitting rib 6a, and the front edge 3' is in contact with the back wall 1' of the front mounting section 1, so that the rear edge 3' is pushed from the front panel 5 of the front mounting section 1. It prevents it from falling off and securely holds it, and also serves as a beam to strengthen the chassis structure.

As explained above, according to the present invention, the chassis components are installed using an insertion method without using screws, and the chassis body is also installed on the front panel of the equipment using an insertion method without using screws. When it is covered, the chassis component fittings act as beams to firmly hold each part and strengthen the chassis structure, so there is no need for screws or other mounting parts to attach each part, making installation easy. In addition, the chassis is not unnecessarily strengthened, which is very effective in terms of cost and workability.
