Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a housing structure for an electrical connection device, such as a cordless telephone connection device.

(Prior Art and Problems) Conventionally, the housing structure of this type of cordless telephone connection device is complicated, as shown in the bottom sectional view and side view of FIGS. 2a and 2b, respectively, and the number of screws is small. There were many things. That is, the small electronic circuit board 2 on which the connector etc. are mounted and the large size electrical circuit board 4 on which the transmitting/receiving unit 3 etc. are mounted, for example, are connected by a total of four screws 6A through the collar.
~6D is screwed to a part of the housing body 7. Further, the housing cover 8 is screwed to the housing body 7 with two short screws 9A and 9B.
11 is an antenna. In this way, the structure of the housing body and housing cover itself is complex, and there are many screws for screw fixing, so there is a disadvantage that the number of steps during manufacturing and assembly increases, resulting in high costs. There was a problem in that adjustment and maintenance required time and effort.

(Purpose of the invention) The purpose of the invention is to solve the problems of the prior art, and in order to achieve that purpose,
``Tatsupin bosses, pin bosses, protruding bosses, etc. are integrally molded from plastic on the inner surface of the housing body, creating a structure in which two large and small electronic circuit boards can be fixed with just two screws.''

(Embodiment) Hereinafter, the structure of the housing of the cordless telephone connection device as an embodiment of the present invention shown in FIG. 1 will be explained in detail.

In FIG. 1, the same reference numerals are used for the same or the same members as those explained in FIGS. 2a and 2b, and detailed explanation thereof will be omitted. The housing main body 20 is made of, for example, plastic material, and the inner surface thereof is provided with a pair of left and right tut pin bosses 21A, 21B, a pair of left and right elongated pin bosses 22A, 22B, and a pair of left and right protruding bosses 23A, 23B. There are cover fixing holes 25A and 25B for easily fixing the body cover 24 to the device, and a cover fixing flange 26 with an internal thread at the bottom.
There is one location.

On the other hand, the housing cover 24 is also made of plastic material, and includes cover fixing claws 27A and 27B for fitting into the holes 25A and 25B, and a flange 26.
A hole 28 for screwing a short pin screw 27 into the internal thread of the pin boss 29A, 29 for fitting with the tips of the pin bosses 22A, 22B.
B is provided. Two large and small electronic circuit boards 3
and 4 and the antenna 11 are the same as those described in FIG.

The assembly of the casing structure described above will be explained below. First, the pin bosses 22A and 22B are inserted one after another into the respective holes 30A and 30B drilled in the two boards, and into the collar 5 and the holes 31A and 31B, and then two long pin screws 32A and 32B are inserted into the holes 30A and 30B. It passes through the hole drilled in the substrate and the collar 5 and is screwed into the tuft pin bosses 21A and 21B. As a result, the two boards 2 and 4 are firmly screwed to the housing body 20. At this time, the protruding boss 2
3A, 23B are inserted and fitted into holes 33A, 33B made in the larger substrate 4 with their small diameter portions at their tips.

After that, the case cover 24 is attached to its claws 27A, 27.
B indicates holes 25A and 25B provided in the housing body 20.
Then, the tuft pin screws 27 are screwed into the flanges 26 and the housing cover 2 is attached.
4 is fixed to the housing 20.

(Effects of the invention) As described above, according to the casing structure of the invention, not only the structure of the casing body and the casing cover itself is simple, but the number of screws for mounting the board is reduced from the conventional six. Since the number of screws for attaching the housing cover has been reduced to two, and the number of screws for attaching the housing cover has been reduced from the conventional two to one, there is a remarkable effect of reducing manufacturing costs and saving labor and time during adjustment and maintenance. is demonstrated.
