Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a housing structure of a telephone.

[Conventional technology]

Generally, a phone case is constructed by integrally connecting an upper case and a lower case, which are formed into two halves with setscrews, elastic engagement pieces, etc., and is used to house speakers, pushbutton dial switches, printed circuit boards, etc. Contains built-in components. For connection using set screws, cylindrical bosses are integrally provided on the inner surfaces of the upper and lower cases to ensure sufficient strength at the screw attachment parts, and the setscrews are screwed into these bosses. . Then, the speaker is mounted and fixed at a location corresponding to the sound emitting hole on the inner surface of the upper case or the inner surface of the lower case via a suitable speaker mounting member.

[Problem that the invention attempts to solve]

By the way, for particularly tall phone cases, it is necessary to make the boss part long, but this also increases the thickness, which can cause sinks caused by the boss part when molding the upper and lower cases. There was a problem in that dents were formed on the surface of the case, significantly deteriorating the quality of the external appearance of the case. Therefore, there is a need for some kind of countermeasure to solve the problem of sink marks in tall housings.

[Means for solving problems]

The casing structure of the telephone according to the present invention was made to solve the above-mentioned problems, and a recess for a handhold is provided in a part of the casing consisting of an upper case and a lower case. An opening is provided on the bottom surface, a speaker mounting member that closes this opening is arranged and fixed inside the upper case, and the lower case is attached to the upper case with a set screw through a boss provided integrally with this speaker mounting member. It is designed to be fixed.

[Effect]

In this invention, since the boss part is integrally provided on the speaker mounting member that is formed separately from the upper case, there is no need to provide a boss part on the upper case, and therefore, sink marks caused by this boss part occur. Further, since the upper case and the lower case are connected using the speaker mounting member, an increase in the number of parts can also be prevented.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a cross-sectional view showing an embodiment of the casing structure of a telephone according to the present invention, and FIG. 2 is an external perspective view of the casing. In these figures, 1 is a relatively tall upper case, 2 is a shallow lower case that closes the bottom opening of the upper case 1, and these two cases 1 and 2 constitute the phone housing 3. are doing. The upper surface of the front half of the upper case 1 is curved forward and downward at an appropriate curvature, and is provided with a plurality of mounting holes 4 for dial buttons (not shown). On the other hand, the upper surface of the rear half of the upper case 1 constitutes a mounting section 5 for a transmitter/receiver (not shown), and a recess 6 for a handhold that opens toward the back side is provided below. This recess 6 is very effective especially when holding the tall housing 3 together with the handset and makes it easy to carry. Then, the mounting section 5
In other words, on the lower surface of the recess 6, on the ceiling surface 7 of the recess 6, a plurality of protrusions 8 extending in the left-right direction are arranged in parallel at appropriate intervals to prevent the hand from slipping.

On the other hand, an opening 1 is provided in the center of the bottom surface 9 of the recess 6.
0 is provided, and a speaker mounting member 11 closes this opening 10 from the inside of the upper case 1. The speaker mounting member 11 is integrally formed of plastic, and a sound emitting hole 12 consisting of many small holes or slits is formed in the center thereof, and a cylindrical portion for accommodating the speaker surrounding the sound emitting hole 12 is formed in the center of the lower surface. 13 is integrally provided in a protruding manner, and a speaker 14 is housed and fixed within this cylindrical portion 13. In addition, tongue-shaped screw attachment parts 16 and 17 are integrally protruded from the front and rear ends of the speaker storage cylinder part 13, and a pair of left and right cylindrical bosses extending downward are provided on both sides of the rear end. A portion 18 is integrally provided in a protruding manner.

The inner surface of the upper case 1 has the screw mounting portions 1.
Cylindrical boss portions 19 and 20 are integrally vertically provided corresponding to the screws 6 and 17, and the respective screw mounting portions 16 and 17 are firmly fixed to the boss portions 19 and 20 by setscrews 21, respectively. There is.

On the other hand, a pair of left and right boss portions 23 are integrally protruded from the rear end of the inner surface of the lower case 2 in correspondence with the boss portions 18 . The boss portion 23 is a cylindrical body that opens on the lower surface side of the lower case 2, and a set screw 24 is inserted from below the lower case 2 and screwed into the boss portion 18, so that the rear end of the lower case 2 is connected to the speaker. It is fixed to the upper case 1 via a mounting member 11. Further, the front ends of the upper case 1 and lower case 2 are also integrally connected and fixed by setscrews 28 screwed into boss parts 26 and 27 provided on the inner surfaces of both cases 1 and 2 from below of the lower case 2. has been done.

Here, if the boss part 18 is integrally vertically disposed on the bottom surface 9 of the recess 6, the distance from the bottom surface 9 to the lower opening of the upper case 1 is large, and therefore the boss part 18 becomes long and thick, causing sinkage during molding. However, in this embodiment, since the boss portion 18 is provided on the speaker mounting member 11 that is manufactured separately from the upper case 1, there is no boss portion 18 on the upper case 1.
Therefore, no dents are formed in the upper case 1, and its appearance is good. on the other hand,
Although the boss portion 26 is provided integrally with the upper case 1, since the boss portion 26 is provided at the low front end portion of the upper case 1, its length is short, which may cause sink marks. It won't happen.
Furthermore, since the speaker mounting member 11 has the boss portion 18 and serves as a connecting member between the upper case 1 and the lower case 2, there is no need to provide any member other than the speaker mounting member 11, which prevents an increase in the number of parts. .

[Effect of idea]

As explained above, in the case structure of the telephone according to the present invention, a boss is integrally provided on the speaker mounting member fixed to the inner surface of the upper case, and the upper case and the lower case are connected via the boss with a set screw. Since the structure is configured such that the upper case is integrally connected and fixed, there is no need to provide a boss on the inner surface of the upper case.Therefore, sink marks caused by the boss do not occur on the upper case, and a good appearance quality is achieved. The case is particularly effective when applied to tall phone casings that require a long boss. Further, since the speaker mounting member also serves as a connecting member for the upper case and the lower case, the number of parts does not increase.
