2. Description of the Related Art Conventionally, in this type of cordless telephone, a charging terminal for external charging is attached to a side surface of a case through a fixing and waterproof ring, and a push button device is provided inside the case near the charging terminal. Is arranged so that a push button such as a dial key appears on the front surface of the case.

FIG. 3 shows the structure of such a conventional cordless telephone. In FIG. 3, 31 is a case, 3
2 is a charging terminal, 33 is a fixing and waterproof ring for the charging terminal 32, and 34 is a push button device. The case 31 includes a front case 35 and a rear case 36. Front case 35
Has a through hole 37 for a push button 49 on the front surface, and an insertion hole 38 and a concave groove 39 for the charging terminal 32 on the side surface. The rear case 36 has a concave groove 40 on one side surface that is continuous with the concave groove 39 on the side surface of the front case 35, and these are combined to form a holding groove 41 for the charging terminal 32. Grooves 43 and 44 for the case packing 42 are provided at the end edges of the cases 35 and 36 facing each other.
The push button device 34 includes a printed circuit board 46 having contacts 45.
And the contacts 45 mounted on the printed circuit board 46.
An elastic rubber member 48 having a contact 47 capable of contacting the elastic rubber member 48 and a push button 49 for pressing the elastic rubber member 48 are provided.

In the charging terminal 32, a fixing and waterproof ring 33 is attached around the charging terminal 32, and the charging terminal 32 is attached to the insertion hole 38 on the side surface of the front case 35. It is fixed by being pressed and held in the holding grooves 41 on the side surfaces of 35 and 36.

On the other hand, in the push button device 34, the push button 49 is mounted in the front case 35 in the vicinity of the charging terminal 32, and the push button 49 projects from the through hole 37 of the front case 35.

[0006]

However, in the above-mentioned conventional cordless telephone, a fixing and waterproof ring is required to attach the charging terminal to the front case, and the push button device is arranged in the vicinity of the charging terminal. However, since they are attached separately, there is a problem that the structure as a whole is complicated, assembly is troublesome, and the cost becomes high.

The present invention solves such a conventional problem, and the charging terminal and the push button device can be easily attached with a simple structure, and the cost can be reduced. An object is to provide an excellent cordless telephone.

[0008]

In order to achieve the above object, the present invention provides a fixing and waterproof ring mounted around a charging terminal which is pressed and held between the front case and the rear case by fixing them. Is integrally provided on the edge portion of the elastic rubber member that constitutes the push button device arranged near the charging terminal.

[0009]

Therefore, according to the present invention, the fixing and waterproof ring for the charging terminal is integrally provided at the edge of the elastic rubber member constituting the push button device, so that a separate ring is used as in the prior art. Unlike the above, since the push button device and the charging terminal can be integrated, the charging terminal can be easily assembled.

[0010]

1 and 2 show the construction of an embodiment of the present invention. 1 and 2, 1 is a case, 2 is a charging terminal, and 3 is a push button device. The case 1 includes a front case 4 and a rear case 5. The front case 4 has a through hole 6 for a push button 18 on the front surface, and a ring fitting groove 7 formed inside the front case 4 and a charging terminal 2 continuously formed outside the one side surface. It has a groove 8 that can be fitted. The rear case 5 has a concave groove 9 continuous to the concave groove 8 of the front case 4 on one side surface thereof, and these are combined to form a holding groove 10 for the charging terminal 2. Further, grooves 12 and 13 for the case packing 11 are provided at the end edges of the cases 4 and 5 which face each other. The push button device 3 includes a printed board 15 having a contact 14, an elastic rubber member 17 having a contact 16 mounted on the printed board 15 and capable of contacting the contact 14, and a push button for pressing the elastic rubber member 17. And a ring portion 19 for fixing and waterproofing the charging terminal 2 which can be fitted in the ring fitting groove 7 on the side surface of the front case 4 is integrally provided at one side edge portion of the elastic rubber member 17. Has been. The ring portion 19 has a hole 20 continuous with the holding groove 10 on the side surface of the front case 4 and a notch portion 21 for inserting the charging terminal 12.

Next, the assembly of the above embodiment will be described. In the above embodiment, first, the charging terminal 2 is attached to the ring portion 19 integrally provided on the elastic rubber member 17 of the push button device 3 to integrate the push button device 3 and the charging terminal 2. This mounting is easily performed by connecting the charging terminal 2 to the notch 21 of the ring portion 19. Next, the push button device 3 is housed in the front case 4, the push button 18 is inserted into the through hole 6 on the front surface of the front case 4, and the charging terminal 2 attached to the ring portion 19 at the side edge of the elastic rubber member 17 is inserted. The front case 4 side groove 8
Fit inside. Then, the front case 4 and the rear case 5 are overlapped with each other via the case packing 11 and fixed, whereby the ring portion 19 is pressed and sandwiched, and the charging terminal 2 attached to the ring portion 19 is attached to the front and rear cases. 14,
It is pressed and held in the holding groove 10 of 15 to be fixed.

As described above, according to the above-described embodiment, the fixing and waterproof ring portion 19 for the charging terminal 2 is integrally provided at one side edge portion of the elastic rubber member 17 forming a part of the push button device 3, By mounting the charging terminal 2 on the ring portion 19 to integrate the push button device 3 and the charging terminal 2 into the front case 4, the front case 4 and the rear case 5 are fixed together. Since the charging terminal 2 is pressed and held in the holding groove 10 provided on the side surface, it is not necessary to separately provide a ring for the charging terminal 2, and as a whole, the assembly can be easily performed and the cost can be reduced. be able to.

[0013]

As is apparent from the above embodiment, the present invention charges the fixing and waterproofing ring mounted around the charging terminal which is pressed and held between the front case and the rear case by fixing them. Since it is integrally provided on the edge portion of the elastic rubber member constituting the push button device arranged near the terminal, it is not necessary to separately provide a ring for the charging terminal, and the assembly as a whole can be easily performed. It has an effect that the cost can be reduced.
