Description

[Detailed description of the invention] The present invention is a device for attaching a switch to a handset, in particular, a switch as a call button provided on the handle of the handset is closed, and the handset is used as an interphone to make a call. The present invention relates to a switch mounting device for a handset of a voice calling telephone which is used as a normal telephone by opening the switch.

Conventional switch devices of this type have a specially designed leaf spring-type switch that is integrally assembled inside the grip, making assembly of the switch cumbersome and costly, and in the event of a switch malfunction, the transmission and reception will be interrupted. There were inconveniences such as having to replace the container itself with a new one.

The present invention was proposed in view of the above, and provides a switch mounting device for a handset that allows a commercially available push-button switch to be removably assembled to the handle of a handset with simple operations, and in the event of a failure, only the switch can be replaced. The purpose is to provide.

Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 is a partially removed front view of a transmitter/receiver employing the switch mounting device of the present invention, Fig. 2 is a plan view of the switch mounting part, Fig. 3 is a cross-sectional view along the line shown in Fig. 2, 4 is a longitudinal sectional view taken along the line of FIG. 2, and FIG. 5 is an exploded perspective view of the switch mounting device. In FIGS. 1 to 5, the transmitter body 1
has a transmitter housing 2 on one end and a handset housing 3 on the other end.
The handle 1a of the handset main body 1 is provided with a lid 4 forming a part of both the storage parts 2 and 3.
Vertical and horizontal ribs 5 and 6 are integrally formed in the interior of the grip portion 1a, and a switch 7 as a call button is detachably assembled into the grip portion.

In order to assemble the switch 7, the illustrated example uses a pair of holders 8, 8 that hold the switch, and an operating member 9 that operates the open/close button 7a of the switch 7. Each of the holders 8, 8 has a pin 11 on the side surface to be inserted into a hole 10 on the side of the switch, a Y-shaped elastic portion 12 on the top surface, and a lateral groove 13 that engages with the horizontal rib 6 in the grip portion on the bottom surface. There is. On the other hand, the operating member 9 is provided with a cover 14 that covers the open/close button 7a of the switch.
and protruding pieces 15, 15 protruding to the left and right of the cover 14.
At the tip of each protruding piece, there is a bifurcated part 16,1 which sandwiches the vertical leg 12a of the Y-shaped elastic part 12.
6 is formed. These holders and operating members are molded, for example, from synthetic resin.

The present invention has the above configuration, and the switch 7 is assembled to the handset body as follows. That is, the operating member 9 is attached to the open/close button 7a of the switch.
cover 14 of the pair of holders 8, 8, and insert the pin 11 on the side of the holder so that the vertical leg 12a of the Y-shaped elastic portion 12 on the upper surface thereof enters the bifurcated portion 16, 16 of the operating member 9. the switch 7 is inserted into the hole 10 of the switch 7. Next, the switch 7 held between the pair of holders 8, 8 is fitted between the vertical ribs 5, 5 of the grip portion 1a, and the lateral grooves 13 on the lower surface of the holder are engaged with the lateral ribs 6. In this case, since the width dimension W of the switch 7 held between the pair of holders 8, 8 and the gap dimension W between the vertical ribs 5, 5 are approximately equal, the vertical ribs 5, 5 can be used to The front and rear positions are determined by the engagement between the horizontal ribs 6 and the horizontal grooves 13, respectively. Then, the cover body 4 is placed over the grip part 1a so that the cover 14 of the operating member 9 comes out from the hole 17, and the cover 17 is attached to the outer circumferential threaded parts 2a, 3a of the transmitter storage part 2 and the handset storage part 3. 18 to attach the lid 4 to the transmitter/receiver body 1, and press the horizontal wing pieces 12b, 12b of the Y-shaped elastic part 12 with the back surface of the lid 4 to firmly secure the switch 7. It is assembled into a predetermined position on the grip.

As described in detail above, the present invention utilizes a pair of holders that hold the switch and the vertical and horizontal ribs in the grip of the handset to hold the switch as a call button without using any mounting screws or the like. Since it is assembled into the transmitter/receiver, there is no need to process screws for attaching the switch to the transmitter/receiver, and since the process is easy and a commercially available switch can be used, it can be constructed at low cost. Furthermore, when a switch or the like breaks down, the switch can be removed in the opposite order to the above-mentioned assembly order, so that maintenance, inspection and replacement of the switch can be easily performed.

The lid 4 may be attached to the grip portion 1a in any manner, but as shown in the illustrated example, the lid 4 is formed integrally with a portion of the transmitter housing 2 and the handset housing 3. A lid 17 attached to both the storage parts 2 and 3,
18, the lid body 4
No mounting screws are required for installation, and a transceiver with a good appearance can be obtained.

Incidentally, instead of forming the pins 11 as described above on the side surfaces of the pair of holders 8, 8, as shown in FIG.
The switch 7 may be held within this recess. Further, the vertical and horizontal grooves formed on the lower surfaces of the pair of holders 8 and 8 are engaged with the vertical and horizontal ribs 5 and 6 in the grip part to fix the switch 7 in a predetermined position so as not to shift. You can also do it.

Wiring to the switch 7 is performed using the space within the grip portion 1a.
