Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transmitter fixing structure for fixing a transmitter to a handset such as a telephone.

[Conventional technology]

A transmitter is fixed from the inside to a casing that constitutes a telephone handset.

FIG. 2 is a partially exploded sectional view of a telephone handset for explaining a conventional transmitter fixing structure in a telephone handset. In the same figure, housing 1
A plurality of voice transmitting holes 2 are provided in the voice transmitting portion, and a step 5 is provided on the inner surface of the voice transmitting portion to allow the tongue portion 4 of the transmitter presser rubber 3 to be inserted therein. The transmitter presser rubber 3 has an insertion opening, and the above-mentioned tongue portion 4 is formed in the lower opening thereof. The upper portion of the tongue portion 4 is tapered to form a constricted portion, and a flange portion 7 for press-fitting and fixing the transmitter 6 is formed on the inner surface near the upper opening.

As mentioned above, the transmitter presser rubber 3 that holds the transmitter 6 is connected to the first and second transmitter presser fittings 8 and 9.
It is fixed to the inner surface of the transmitting section of the housing 1 with screws 10. 4 and 5 are for explaining this, FIG. 4 is a perspective view, and FIG. 5 is a plan view taken from the direction of arrow Y in FIG. 2. As shown in FIG. 4, the first transmitter presser fitting 8 has a ring portion 8a that comes into contact with the upper surface of the tongue portion 4, and a protrusion portion 8b that is formed to protrude upward from the ring portion. 8
A protrusion 8c is formed at the tip of b.

This first transmitter presser fitting 8 is fixed as shown in FIG. That is, the protrusion 8c is inserted into the opening 11 formed in the flat second transmitter presser fitting 9. The second transmitter presser fitting 9 is fixed to the housing 1 by screwing the screw 10 into the boss portion 12.

Next, the operation of the above conventional example will be explained. The first and second transmitter presser fittings 8 and 9 cooperate with each other to press and fix the tongue portion 4 of the transmitter presser rubber 3 against the inner surface of the housing 1. At the same time, the first and second handset holders 8, 9 function as weight adjustment weights, thereby giving the handset the proper weight required.

[Problem that the invention attempts to solve]

However, the conventional structure described above requires two types of transmitter holding fittings to fix the transmitter, which increases the number of parts and raises the cost of parts. Further, there was also a problem in that the assembly process required many steps for attaching and fixing the transmitter presser fitting.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a transmitter fixing structure that can reduce the number of parts to reduce component costs and also reduce the number of assembly steps.

[Means for solving problems]

In the transmitter fixing structure according to the present invention, the transmitter presser metal fitting is constituted by one metal fitting having an opening in the center, and the constricted part of the transmitter presser elastic member is inserted into this opening, and The open end of the transmitter is brought into contact with the tongue of the elastic member for holding the transmitter, and the fitting is fixed to the housing at the mounting part formed around the transmitter presser. The present invention is characterized in that the transmitter presser elastic member to be held is pressed and fixed to the transmitter part of the housing.

[Effect]

Since the transmitter fixing structure according to the present invention is configured as described above, one transmitter presser fitting fixes the transmitter presser elastic member that holds the transmitter to the inner surface of the casing at its tongue portion. In addition to working as a weight for adjusting the weight.

[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 3 of the accompanying drawings. Note that the same elements as those in FIG. 2 are given the same reference numerals, and redundant explanations will be omitted.

FIG. 1 is a partially exploded cross-sectional view of a handset for explaining the transmitter fixing structure according to the embodiment;
FIG. 3 is a plan view of the fixing structure shown in FIG. 1, viewed from the direction of arrow X. This is particularly different from those shown in FIGS. 2, 4, and 5 in that the transmitter presser fitting 21 is constituted by a single piece of metal fitting. The transmitter holding bracket 21 has an opening 2 in the center.
1a, through which the constricted portion of the transmitter presser rubber 3 is inserted. The open end 21b of the transmitter presser fitting 21 is formed into a flat surface, and comes into contact with the upper surface of the tongue portion 4 of the transmitter presser rubber 3. Therefore, the opening 21a of the transmitter presser fitting 21 needs to be larger than the constriction of the transmitter presser rubber 3 and smaller than the tongue portion 4.

Both ends of the transmitter presser fitting 21 are bent upward, and the tip is bent outward again to form a mounting portion 21c. Two openings are provided in the mounting portion 21c, and the screw 10 is screwed into the boss portion 12 formed to protrude from the housing 1 through the openings. Further, the depth of the step 5 formed on the inner surface of the transmitter section of the housing 1 is smaller than the thickness of the tongue section 4 of the transmitter presser rubber 3. The open end portion 21b of the holding fixture 21 is configured to press against the housing 1 from the inside.

Next, the operation of the above embodiment will be explained. One transmitter presser fitting 21 is attached to the housing 1 at the mounting portion 21c.
The lower surface of the opening end 21b abuts against the upper surface of the step 5 of the housing 1. At this time, since the thickness of the tongue portion 4 is greater than the depth of the step 5 as described above, the transmitter presser rubber 3 is stably fixed to the transmitting portion of the housing 1. In addition, the transmitter presser fitting 21
Since it has a predetermined weight, it also acts as a weight for adjusting the weight of the handset.

The fixing structure according to the above embodiment is assembled, for example, as follows. First, the transmitter 6 is press-fitted into the flange portion 7 of the transmitter presser rubber 3 and fixed. Next, using the elasticity of the tongue piece 4, the transmitter presser rubber 3 is
is press-fitted into the opening 21a of the transmitter presser fitting 21 from below, and its constricted portion is inserted into the opening 21a.
Next, the transmitter presser rubber 3 is set in the transmitting part of the housing 1, and the screw 10 is inserted into the opening of the mounting part 21c and screwed into the boss part 12, thereby obtaining the structure shown in FIG. It will be done.

The present invention is not limited to the above embodiments, and various modifications are possible. For example, in the embodiment, the transmitter presser fitting is formed from a rectangular flat plate, but the present invention is not limited to this, and materials of various shapes can be used. Further, the number of screws for fixing the transmitter presser fitting is not limited to two, but may be three or more.

[Effect of idea]

As explained above in detail, according to the present invention,
There is only one transmitter presser metal fitting, which has the function of fixing the transmitter presser rubber to the housing and also functions as a weight for weight adjustment, reducing the number of parts and reducing material costs. This has the effect of reducing the number of assembly steps.
