Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handset having an internal communication circuit and a switch, and aims to facilitate its assembly.

An embodiment of the present invention will be explained below with reference to the drawings. In FIGS. 1 and 2, 1 is an upper case of the handset, 1A and 1B are engaging parts, 2 is a cushioning material such as a sea wire that comes into contact with the magnet part of the speaker 3, 4 is a packing of the speaker 3, 5 is a wire for connecting the speaker, 5A is a male connector connected to the wire 5, 5B is a female connector connected to the male connector A, 6 is a switch unit, 7 is a wire for connecting the switch, 7A is a male connected to the wire 7 The connector 7B is a female connector coupled to the male connector 7A, and 8 is a microphone holder. 9 is a microphone, 10 is a wire for connecting the microphone,
10A is a male connector connected to wire 10, 10B
is the female connector connected to this male connector, 11,
12 is a printed circuit board forming a live circuit, 11A
is the microphone mounting hole, 12 is the handset cord, 1
2A is the male connector connected to this cord 12, 1
2B is a female connector coupled to a male connector, 13 is a lower case of the handset, and 14 is a set screw. 13A is a long hole, 13B is an insertion hole for the set screw 14, 13C is a microphone mounting part, 13D is a switch unit mounting part, 13E is a speaker mounting part, 13F
13 is a hole through which a part of the foot lever 6A protrudes;
G, 13H are engagement parts, 13J is printed circuit board 11
This is the mounting part.

In this case, female connectors 5B, 7B, 10B, and 12B are attached in advance to the printed circuit board 11 in addition to the parts forming the communication circuit. In addition to the switch that is turned on and off by the operation of the foot lever 6A, the switch unit 6 also has a built-in volume, whose terminal 6B protrudes from a long hole 13A formed in the lower case 13 of the handset, so that the volume can be adjusted from the outside. .

A method of assembling such a handset will be explained. Connect the speaker 3 to the speaker attachment part 13E of the handset lower case 13 via the speaker packing 4.
At the same time, the switch unit mounting part 13
D is switch unit 6, printed circuit board mounting part 1
Printed circuit board 11 and printed circuit board 11 on 3J
The microphones 9 are mounted in the same direction through the microphone mounting holes 11A provided in the respective holes.

Next, the male connectors 9A, 7A, 10A, 12A connected in advance to the speaker 3, switch unit 6, microphone 9, and handset cord 12 are connected to the female connectors 5B, 7B, and
10B and 12B, respectively.

After that, the handset upper case 1 is engaged with the handset lower case 13, and then the set screw 14 is inserted from the lower case 13 side and tightened to the upper case 1, so that the upper case 1 and the lower case 13 are integrated. be converted into

At this time, the speaker 3, switch unit 6, and microphone 9 including the printed circuit board 11 are pushed toward the lower case 13 and locked by the cushioning material 2, protrusions, etc. provided inside the upper case 1.

Note that the handset cord 12 may be connected to the female connector after the upper case 1 and the lower case 13 are integrated.

As described above with reference to the embodiments, according to the present invention, the case may be divided into two parts, an upper case and a lower case, and each component (for example, a speaker, a switch unit, a printed circuit board microphone) may be placed on the lower case. All connections are made using the connector connection method, making assembly easier. In other words, it is more rational than mounting or fixing the speaker, printed circuit board, switch unit, and microphone in the case and soldering the lead wires between them.

Claims (1)

[Scope of utility model registration request] A speaker mounting part, a switch unit mounting part, a printed circuit board mounting part, a microphone mounting part, etc. are formed inside the lower case, and each of these mounting parts has a speaker, a switch unit with a foot lever, various female connectors, and a communication circuit. A printed circuit board, a microphone, etc. constituting the circuit board are attached, and a male connector attached to the tip of a wire drawn out from the speaker, switch unit, microphone, etc., respectively, can be freely attached to and detached from the female connector attached to the printed circuit board. In addition, when the upper case is attached to the lower case, the speaker, switch unit, etc. attached to the lower case are attached to the lower case side. A handset with cushioning material, protrusions, etc. that can be pressed.
