Description

[Detailed description of the invention] Industrial application field The present invention relates to a back plate mounting structure of a communication device housing.
In particular, the present invention relates to a back plate mounting structure for a communication device housing that is easy to install.

Prior Art The structure of a conventional communication device housing has a drawback that it is not necessarily easy for a single worker to attach the back plate. For example, in the conventional structure shown in FIGS. 1 and 2, a communication device case back plate (hereinafter referred to as a back plate) 2 is attached to and removed from a communication device case main body (hereinafter referred to as a main body) 1. In order to do so, it is necessary for the worker 1 to turn the four setscrews 3 into the screw holes 4 of the main body 1 and the screw holes 5 of the back plate 2 while supporting the back plate 2.
It is not easy for people to attach and detach it.

In addition, in the conventional structure shown in FIG.
This is intended to facilitate the attachment and detachment of the back plate 2 to and from the main body 1 by a person. However, in this conventional structure, it is necessary to provide an overlapping portion 7 so that a large gap 6 does not occur between adjacent back plates 2 due to vertical displacement of the back plate 2. However, there is a drawback that large dents between adjacent back plates cannot be avoided. Furthermore, in the structure shown in Fig. 3, the back plate 2 has a vertical orientation, which makes it difficult to handle, and if you accidentally release your hand while supporting the back plate 2 with a single set screw 3, the back plate 2 rotates around its set screw 3, which may cause damage to the main body 1 and other products.

Purpose of the Invention The purpose of the present invention is to provide a back plate mounting structure for a communication device casing that can be easily and safely attached and detached by a single worker in order to solve the above-mentioned drawbacks of the prior art.

Structure of the Invention In order to achieve the above object, the back plate mounting structure of the communication device casing according to the present invention includes a tongue piece projecting diagonally upward from the back end surface of the communication device casing main body, and a tongue piece of the communication device casing back plate. The tongue piece is provided with a protrusion projecting diagonally downward from a portion corresponding to the tongue piece, and a means for locking the back plate to the main body, and the back plate is positioned by placing the protrusion on the tongue piece. have

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 4 shows a partially cutaway perspective view of an embodiment of the present invention, and FIG. 5 shows a sectional view of the back plate in a locked state.
In the figure, an inverted L is placed at an appropriate position on the back end surface of main body 1.
A character-shaped member 8 is attached, and a portion of the member 8 is configured to form a tongue piece 8a projecting obliquely upward from the rear end surface of the main body 1. A protrusion 9 protruding obliquely downward is provided on the surface of the back plate 2 facing the main body at a portion corresponding to the tongue piece 8a. The position of the tongue piece 8a on the back end surface of the main body 1 and the position of the protrusion 9 on the back plate 2 are appropriately selected, and when the protrusion 9 is placed on the tongue piece 8a, the back plate 2 is properly positioned with respect to the main body 1. is,
The screw hole 4 of the main body 1 and the screw hole 5 of the back plate 2 are aligned so that the set screw 3 can be immediately screwed into both the screw holes 4 and 5. Preferably, the tongue piece 8a and the projection 9 are provided with sufficient strength so that the weight of the back plate 2 is supported by the engagement between the tongue piece 8a and the projection 9.

Referring to FIG. 5, the tongue piece 8a of the main body 1 and the protrusion 9 of the back plate 2 are provided with an equal slope 10 with respect to the horizontal direction H, and the tongue piece 8a is attached to the back plate 2 in order to attach the back plate 2. When the weight is supported, the weight is applied to the side of the main body 1 to prevent the back plate 2 from coming off the tongue piece 8a. Preferably, the protrusion 9 on the back plate 2 is formed by bending a suitable portion of the back plate 2. Furthermore, if the projections 9 are formed vertically symmetrically on each back plate 2,
It is convenient for the worker to proceed with the work without being concerned about the top and bottom of the back plate 2.

In another embodiment of the invention shown in FIGS. 6 and 7, reinforcing folds 11 formed on the periphery of the back plate 2 are used in the same manner as the protrusions 9 in FIG. In this case as well, the reinforcing bent portions 11 are formed vertically symmetrically on the back plate 2, and the inclination angle 10 is set at each bent portion 11 as shown in FIG.
Provided for.

Effects of the invention The effects of the invention are listed below.

(b) Since a single worker can safely and reliably attach and detach the back plate of the communication device case, efficiency and labor savings can be achieved.

(b) Work becomes easier because the vertical direction of the back plate can be eliminated.

(c) Even if you accidentally release your hand from the back plate during attachment/detachment work, the back plate will be held by the slanted tongues and protrusions, so there is no risk of the back plate rotating and damaging surrounding items. It can be avoided.

(d) Since the structure is simple, it can be manufactured at low cost.
