DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing stacking structure in which relatively small housings such as adapters are vertically stacked.

[0002]

2. Description of the Related Art As a stacking structure of this kind of housing,
Protrusions and grooves for fitting are provided on the upper and lower surfaces of the housing, respectively, and when two housings are stacked, the protrusions on the upper surface of the lower housing and the grooves on the lower surface of the upper housing are fitted. It was fixed by that. In addition, as a stacked structure of another housing, a holding member for holding the two housings in a sandwiched manner is provided, and the holding members are held by the engaging means of the holding members themselves, or the holding members are screwed to the housings. Was fixed by that.

[0003]

However, of the above-described conventional stacking structures of housings, in the former,
When using one unit without stacking the housings, a convex ridge for fitting is exposed on the upper surface of the housing. When using multiple housings, a convex ridge is provided on the upper surface of the uppermost housing. However, there is a problem in that the appearance is impaired because of the exposure of the particles. In addition, in the latter case using the holding member, there is a problem that sufficient fixing strength cannot be obtained when the holding member itself is engaged with the engaging means, and when fixing by screwing, the screw is exposed because the screw is exposed. There was a problem that was damaged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object the purpose of stacking the casings without impairing the appearance even when the casing is used alone or when a plurality of casings are used. In this case, the purpose is to improve the fixing strength.

[0005]

In order to achieve this object, according to the first aspect of the present invention, there is provided a housing stacking structure in which the upper and lower surfaces of the housings are brought into contact with each other and the housings are vertically stacked. , A pair of recesses are provided on both sides of the bottom surface of the housing, and the side ends of the housing of the recesses are opened, and at both ends facing each other in a direction orthogonal to the opening, between the bottom surface of the recesses. A pair of flanges forming a guide groove are provided, and a holding member having a length substantially equal to the height of the housing and having a pair of bent portions formed at both ends to be engaged with the guide groove is provided. Fastening means capable of fastening from below is provided between the bent portion of the holding member and the bottom surface of the concave portion. Therefore, the bent portion of the holding member is not exposed from the upper surface side of the housing. The lower bent portion of the holding member is fixed to the lower housing by fastening means, and the upper housing is fixed by the pair of holding members fixed to the lower housing. According to a second aspect of the present invention, in the first aspect of the present invention, two pairs of the concave portions are provided. Therefore, 2
When stacking and fixing two housings, the bent portion of the holding member is engaged in one recess, and when the other housing is further fixed, the holding member is fixed in the other recess. Engage the bend.
