Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a housing structure of a mobile communication device such as an individual call receiver, and in particular, a cover can be attached to a case without using screws and is simple. The present invention relates to a housing structure of a portable communication device that cannot be removed.

[Conventional technology]

FIG. 4 shows an example of a conventional housing structure of a receiver for individual call. In the same figure, a battery case 5 accommodating a battery 6 is integrated into a printed board 4 on which electronic parts and the like are mounted, this is attached to a synthetic resin case 8, and then a cover 9 is provided along the case side groove 83. It is slidably fitted, and further, the screw 10 is fixed to the metal plate nut 82 in the protruding portion 81 provided on the inner surface of the rear end of the case through the cover mounting hole 91. The screw 10 generally has a special shape with a hexagonal screw hole so that the user cannot easily remove the cover 9.

Next, the battery 6 is stored in the battery case 5, and then the battery cover 3 is slid and fitted. The battery cover 3 is designed so that the user can easily remove it when exchanging electricity, and since the tip of the battery cover 3 is engaged with the inside of the cover 9, put the finger on the surface 31 and slide it backward. It can be removed.

[Problems to be solved by the device]

In the above-mentioned conventional housing structure of the portable wireless device, the cover 9 is fixed to the case 8 by using the screw 10. However, in this type of device, there is a failure such as malfunction due to static electricity generated during carrying or destruction of electronic parts. In many cases, in particular, when a metal screw or the like is exposed to the outside, static electricity enters the inside of the housing from there and causes a failure. Further, if the screws are exposed on the outer surface of the housing, the user may remove the cover to view the inside, which may cause a malfunction. Furthermore, assembly,
Not only is it troublesome to tighten and remove the screws when disassembling, but also the case may be damaged by over-tightening the screws.

[Means for solving the problem]

The present invention has at least a case for accommodating a battery, a cover attached to the case, and an electronic cover attached to a battery accommodating portion of the case, and a flexible member provided on an inner surface of the cover. A housing structure of a portable communication device in which the case and the cover are engaged with each other by engaging a sex tongue portion and a stopper provided on the inner surface of the case, the battery cover being provided on the cover. When it is removed from the case, it is exposed to the outside, and a notch portion for releasing the fitting between the case and the cover by elastically deforming the flexible tongue portion by inserting a tool from the outside is provided. It is characterized by having.

〔Example〕

Next, the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of an individual calling receiver housing showing an embodiment of the present invention. The difference from the conventional housing structure is that there is no fixing screw for the case 1 and the cover 2. A rib-shaped stopper 11 is provided on the inner surface of the rear end of the case 1, and a plate-shaped tongue piece 21 is provided on the inner surface of the rear end of the cover 2 as shown by a broken line. As shown in FIG. 2, this tongue piece portion 21 is formed integrally with the cover 2 by synthetic resin and has flexibility, and a hook-shaped projection portion 11 is provided at the tip end portion.

3 (a) and 3 (b) are cross-sectional views showing the coupling mechanism of the case and the cover. When the cover 2 is slid along the groove 12 provided on the opposite side surface of the case 1, first, the tip of the hook-shaped projection 211 of the tongue 21 is the stopper 1 of the case 1.
It contacts the inclined portion 111 of 1. When a force is further applied to slide the tongue piece 21 while elastically deforming the tongue piece 21, the stopper 11 and the hook-shaped projection portion 211 of the tongue piece 21 engage with each other as shown in FIG. 2 does not come out backwards and becomes a connected state. In order to release this combined state, as shown in FIG. 3 (b), the vicinity of the tip of the tongue piece 21 is lifted by using the rod-shaped tool 7 to slide the cover 2 backward (in the direction of the arrow). In this case, the action of lifting the tongue piece 21 is performed from the outside of the housing, but in this embodiment, the tool 7 is inserted through the notch 22 on the cover side which is exposed when the battery cover 3 is removed. This mechanism should be taught only to maintenance personnel.

[Effect of device]

As described above, according to the present invention, since the flexible tongue portion provided on the inner surface of the cover and the stopper provided on the inner surface of the case are engaged with each other, the case and the cover are fitted to each other. The metal screw exposed to the outside of the housing can be removed, and the failure due to static electricity can be prevented. Also, when the battery cover is removed from the case, a tool is inserted from the outside into the notch exposed to the outside, and the flexible tongue part is elastically deformed to release the fitting between the case and the cover. Since the cover cannot be removed, it is possible to prevent malfunctions caused by user mischief. Further, if the synthetic resin is integrally molded, the number of parts can be reduced, and the weight and cost can be reduced.
