DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly structure of a front housing and a rear housing of an electronic device such as a television receiver.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view showing an assembling structure of a conventional electronic apparatus housing of this type shown in Japanese Utility Model Publication No. 50-19371, in which 1 is one housing and 1a is an inside thereof. The protruding inner peripheral wall 1b is a rib provided between the outer peripheral wall and the inner peripheral wall 1a. Further, 2 is the other housing to be connected, 2a is a stepped fitting piece that fits with the housing 1, and 2b is a slit provided in this fitting piece 2a. 5 and 6 are perspective views and cross-sectional views showing other examples, in which 3 is one housing, 3a is a recess provided in the outer shape of this housing 3, and 4 is the other to be connected. The housing 4a is a stepped fitting piece that fits with the housing 3, and the reference numeral 4b is a notch provided in the fitting piece 4a.

Next, the operation will be described. First, in FIG. 4, when the housings 1 and 2 are fitted, the slit 2 of the housing 2
b is fitted simultaneously with the rib 1b of the housing 1. 5 and 6, when the housing 3 and the housing 4 are fitted to each other, the notch 4b of the housing 4 is the recess 3 of the outer shape of the housing 3 as in FIG.
It is simultaneously fitted to the inner circumference of a.

[0004]

Although the conventional equipment is assembled as described above, in the case of FIG. 4, an impact force is generated between the housings 1 and 2 in the direction of arrow C. At this time, since it is difficult to increase the wall thickness of the rib 1b, there is a problem that the rib 1b itself has insufficient strength. In addition, in the case of FIGS. 5 and 6, a cross section of a portion where a shock load is applied between the housings 3 and 4 by providing a concave portion 3a on the outer shape of the housing 3 against an impact force that tends to shift in the direction of the arrow D. Increase the coefficient,
Although the lack of strength is solved, there is a problem in that the appearance becomes concave, which is not preferable in terms of design.

The present invention has been made in order to solve the above-mentioned problems, and has a sufficient strength against a drop impact and the like, and does not impair the appearance of the design, and does not increase the cost of an apparatus housing. An object is to provide an assembly structure.

[0006]

The housing of the device according to the present invention has a change in the thickness of the front housing and the rear housing at portions which cannot be seen in appearance (when one housing is concave, the other housing is concave). Is intended to be fitted with the uneven shape, and at the same time, a fitting holding rib is provided in the vicinity of the uneven shape so that the fitting of the uneven shape does not come off easily. It is a thing.

[0007]

According to the present invention, when the casing is fixed, the concave and convex end faces provided on the casing are fitted to each other. Therefore, it is possible to obtain a fixing structure having a large strength in the direction perpendicular to the end faces. it can.

[0008]

[Embodiment 1] An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 5 is one housing, 5a is a concave portion provided inside the housing 5, and 5b is provided near the concave portion 5a so as to have a concave portion 5d between the concave upper surface 5c. The fitting holding ribs 5e are end faces of the recess 5a. 6 is the other housing, 6a is a stepped fitting piece that fits with the housing 5, and 6b
Is a convex portion provided on the fitting piece 6a, and 6c is an end face of the convex portion 6b.

Next, the operation will be described. When the housing 5 and the housing 6 are fitted as shown in FIG. 2, at the same time, the recess 5 of the housing 5 is
The a and the convex portion 6b of the housing 6 are arranged so as to be fitted to each other with a minute gap in the arrow E direction. At the same time, the fitting holding rib 5b is arranged inside the fitting piece 6a in the vicinity of the uneven portion, and plays a role of holding the uneven fitting so as not to come off. Here, when a drop impact is applied to the television receiver as shown in FIG. 3 and an impact force is generated between the housings 5 and 6 to shift in the direction of arrow E, the impact force is the same as the end surface 5e of the recess 5a. The end surface 6c of the convex portion 6b is received, but the end surface 5c and the end surface 6c have a sufficient shape strength against the impact in the direction of the arrow E, and the fitting holding rib 5b prevents the concave portion. The fitting between 5a and the convex portion 6b does not come off. Therefore, no impact force is generated in the other parts of the housing 5 and the housing 6, and it is possible to prevent damage to the housing 5 and the housing 6.

[0010]

As described above, according to the present invention, the front and rear housings
If the body is about to be displaced due to a drop impact, the displacement direction
Since they are impacted by the mutual contact surfaces that have a large cross section,
Misalignment and damage are prevented. In addition, the fitting retaining ribs
It doesn't get out of sync. It should be noted that the part of the housing that receives the drop impact can be formed by integrally molding the unevenness of the thickness of the housing and the retaining ribs, and sufficient strength can be obtained without increasing the cost, and at the same time, the concave portion on the exterior design surface can be obtained. There is an effect that it can be configured without causing defects such as.
