2. Description of the Related Art Hitherto, as an integrated holding structure of a microphone for a transmitter, a structure described in Japanese Utility Model Application Laid-Open No. 6-19346 is known. FIG. 4 to FIG. 6 show the structure of a conventional microphone holding structure for a transmitter. A transmitter 2 and a receiver 3 are separately provided inside both ends of the housing 1 suitable for grasping, and an operation unit 5 provided with dial and function push buttons 4 is provided near the center, An elastic sheet 7 called a rubber contact, in which a domed elastic receiving portion 6 with a movable contact is arranged in a state corresponding to each push button 4, and a movable portion of the elastic receiving portion 6 inside the operating portion 5. A printed circuit board (printed wiring board) 8 provided with fixed contacts corresponding to the contacts is superposed and arranged, so that only when the push button 4 is retracted, it can move against the elastic receiving portion 6. It is configured to be able to contact the contact. In addition to such a push button switch, a receiver 3 and necessary electrical components (not shown) and a microphone 9 for transmission are provided in the housing 1, and the push button elastic sheet 7 is extended. Then, a microphone 10 for a transmitter is integrally formed with the extension of the microphone, and the top of the holder 10 is pressed against the wall of the housing 1 from the inside while the holder 10 is attached to the microphone 9. Originally, the substrate 8 is fixed to the housing 1.

However, in the above-mentioned conventional integrated microphone holding structure, the microphone holder for the transmission is not affected by the external force such as an elastic sheet for a push button. However, there is a problem that it is difficult to simplify the structure and reduce the cost because it can be integrated only with a member that is not easily transmitted to the vehicle.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a simple structure and a low-cost structure for holding a transmission microphone.

[0005]

In order to achieve the above object, according to the present invention, a joint between a microphone holder and a cover of an external input / output terminal is integrally formed in a U-shape, and a rib provided on a housing is provided. And the printed circuit board press-hold the connecting portion so that even if an external force is applied to the external input terminal, the external input terminal is not transmitted to the microphone holder.

As described above, even if the microphone holder is integrally formed on the cover of the external input / output terminal to which the external force is applied, the external force can be prevented from being transmitted to the holder. An integrated holding structure for the talking microphone is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention relates to a handset telephone having a microphone for transmission provided at one end inside a housing and an external input / output terminal provided at the bottom or side of the housing. The microphone holder and the cover of the external input / output terminal are integrally molded so that the joint part has a U-shape, and the housing has ribs that can be inserted into the U-shape joint part. This is a microphone holding structure that can realize an inexpensive integrated microphone for a transmission microphone with a simple structure, and has the effect of preventing the external input / output terminal cover from being lost.

According to a second aspect of the present invention, the holder is mounted on the microphone, the top of the holder is pressed against the wall of the housing from the inside, and the rib provided on the housing is connected in a U-shape. 2. The microphone holding structure according to claim 1, wherein the printed circuit board to which the external input / output terminals are attached is fixed to the housing in a state where the microphone is inserted into the microphone unit, and the microphone holder is mounted on the microphone. In addition to preventing the ingress of noise from the surroundings, it can also prevent the microphone from vibrating and protect it from mechanical external forces applied to the microphone. This has the effect of making it difficult to transmit to the holder.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. (Embodiment 1) FIG. 1 is a partial longitudinal sectional view illustrating a main part of a handset type telephone to which a microphone holding structure of the present invention is applied, FIG. 2 is an exploded perspective view of the main part of the present invention,
FIG. 3 is a perspective view of a main part of the present invention.

In the present embodiment, a transmitter 2 is provided inside one end of a housing 11 suitable for grasping, and an operation unit 5 in which a push button 4 for dial and function is juxtaposed near the center. And an elastic sheet 7 called a rubber contact in which a domed elastic receiving portion 6 with a movable contact is arranged in a state corresponding to each push button 4 inside the operating portion 5, and an elastic receiving portion 6 And a printed circuit board (printed wiring board) 8 provided with fixed contacts corresponding to the movable contacts of the present invention. Until it is configured to be able to make contact with the movable contact, and furthermore, in addition to such a push-button switch, necessary electrical components (not shown) for the push-button switch and a transmission microphone 9 are provided. Figure From the same as the conventional art described in FIG.

In this embodiment, an external input / output terminal 12 fixed to a printed circuit board 8 is provided at the bottom or side of a housing 11 in addition to the above-described configuration. The cover 14 of the terminal 12 is integrally formed with the cover 14 so that the connecting portion 15 has a U-shape. In assembling, the printed circuit board 8 is fixed to the housing 11 with the holder 13 fitted into the microphone 9 and the rib 16 provided on the housing 11 inserted into the U-shaped connecting portion 15. As a result, the connecting portion 15 can be pressed and held between the rib 16 and the printed circuit board 8 so that the mechanical external force applied to the cover 14 of the external input / output terminal 12 is not transmitted to the microphone holder 13. it can. Therefore, even the cover 14 of the external input / output terminal 12 to which a mechanical external force is applied can be integrated with the holder 13, and a simple structure and an inexpensive integrated microphone for transmission can be realized. In addition, the cover 14 of the external input / output terminal 12 can be prevented from being lost.

In the above description, an example in which only the microphone holder 13 and the cover 14 of the external input / output terminal 12 are integrally formed has been described. It is also possible to integrally mold such as these.

[0013]

As described above, according to the present invention, the connecting portion between the microphone holder and the cover of the external input / output terminal is integrally formed in a U-shape, and the connecting portion is formed by the rib provided on the housing and the printed circuit board. By pressing and holding the external input / output terminal, mechanical external force applied to the external input / output terminal cover can be prevented from being transmitted to the microphone holder. The effect of being able to be integrally formed with the microphone holder and obtaining an inexpensive integrated structure for the transmission microphone with a simple structure is obtained.
