Abstract

PROBLEM TO BE SOLVED: To obtain a structure of a communication equipment by removing a trunk line extension unit simply from a front case without disassembling a communication equipment case. SOLUTION: A mount pocket in which an extension unit 2 is dropped is formed to a front case of a communication equipment case and a fixed claw 4a of a couple of elastic pieces 4 provided to both sides of the mount pocket is locked removably to an inner fixed rib of the mount pocket. In the communication equipment structure of as above, a couple of notches 10 in which a tip of a tool such as a screw is inserted are formed to both sides of the mount pocket corresponding to each elastic piece 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a telephone, and more particularly to a casing structure of the communication device.

[0002]

2. Description of the Related Art As is well known, for example, in a conventional telephone case 1A as shown in FIG. 4, it may be desired to selectively add an extension unit such as a function extension unit or a station line extension unit 2A after the installation. .

That is, for this purpose, the surface case 1
A telephone case 1A composed of a and a lower case 1b has a mounting pocket 3 for receiving a station line extension unit 2A.
A is formed, and a pair of elastic pieces 4A extending downward are integrally formed on both sides of the station extension unit 2A, and the tip of the elastic piece 4A is inserted into the mounting pocket 3A corresponding to these elastic pieces 4A. Fixed rib 5 with which the fixed claw 4a is locked
A is integrally molded.

[0004]

Therefore, in such a conventional telephone structure, when the station line extension unit 2A is added, the station line extension unit 2A is elastically deformed while the elastic pieces 4A on both sides of the station line extension unit 2A are elastically deformed. Since the station line extension unit 2A is fixed to the front case 1a by the fixing claws 4a simply by dropping the extension unit 2A into the mounting pocket 3A, there is an advantage that the telephone case 1 can be easily assembled.
When it becomes necessary to remove the station extension unit 2A from A, there is the inconvenience of disassembling the relationship between the surface case 1a and the lower case 1b.

That is, in order to remove the fixing claw 4a of the elastic piece 4A from the fixing rib 5A, the surface case 1a and the lower case 1b are to be removed.
Is disassembled, the tip of the tool is applied to the fixing claw 4a from below the surface case 1a, the fixing claw 4a is removed from the fixing rib 5A, and the station line extension unit 2A is removed from the surface case 1a. And the lower case 1b had to be reassembled.

In view of the problems of the conventional communication equipment structure as described above, it is an object of the present invention to perform communication in which the station line extension unit can be easily removed from the surface case without disassembling the communication equipment case. To get the equipment structure.

[0007]

In order to achieve this object, the present invention provides a pair of elastic pieces provided on both sides of the mounting pocket, in which a mounting pocket into which an extension unit can be dropped is formed in a surface case of a communication device case. In the communication equipment structure in which the fixing claws of the above are detachably locked to the fixing ribs inside the mounting pocket, a pair of cuts capable of inserting a tool tip such as a screw driver to both sides of the mounting pocket corresponding to each elastic piece. The present invention proposes a communication device structure that forms a notch.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 shows a telephone case 1 (communication device case) embodying the present invention. The telephone case 1 has a resin surface on which function buttons 6, dial numeric keys 7, office line buttons 8 and the like are arranged. Case 1a and this front case 1
The lower case 1b that covers the lower side of a is composed of
It is the same as the conventional one.

Although a mounting pocket 3 corresponding to the outer shape of the extension line unit 2 (extension unit) is formed on the surface of the surface case 1a, the surface of the extension line unit 2 of resin is formed by resin molding. Multiple extension station line buttons 9
Are arranged. A pair of small notches into which the tips of tools such as the screw driver B can be inserted are provided on both sides of the station extension unit 2 corresponding to the pair of fixing ribs 5 arranged on both sides inside the mounting pockets 3. 10 are formed, elastic pieces 4 extending downward are integrally formed inside these notches 10, and fixing claws 4a at the tips of these elastic pieces 4 face the corresponding fixing ribs 5.

Since the telephone structure according to the illustrated embodiment has the above-mentioned structure, the attachment pocket 3 of the telephone case 1 is provided.
The elastic piece 4 is elastically deformed and the fixing claw 4a of the elastic piece 4 is fixed to the fixing rib 5 only by dropping the station line extension unit 2 into. To remove the extension unit from the telephone case 1, insert the tip of the screw driver B into the notch 10 as shown by the phantom line in FIG. 3, the elastic piece 4 is elastically deformed, and the fixing claw 4a is fixed to the fixing rib. Since it is separated from 5, the maintenance can be performed without disassembling the surface case 1a and the lower case 1b.

In the above description of the embodiment, an example in which it is applied to a station line extension unit has been described, but the present invention can also be applied to other extension units such as a function extension unit. It is needless to point out again that it can be applied not only to the telephone housing but also to other communication device structures.

[0013]

As is apparent from the above description, according to the present invention, a pair of notches are formed on both sides of the extension unit facing the elastic piece, and communication is performed without using a special tool. It is possible to obtain a communication device structure in which an extension unit can be easily removed from the communication device case without disassembling the device case and maintenance is easy.
