Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a telephone/intercom wire fixing structure, and particularly relates to a telephone/intercom wire fixing structure that can elastically hold the wiring at all times and securely fix it. .

[Technical Background of the Invention and Problems to be Solved] Conventionally, a telephone/interphone wire fixing structure as shown in FIG. 4 has been known. This telephone/interphone wire fastening structure includes terminals 12 for connecting electric wires 11 such as cables on a telephone/interphone housing 10, a resin wire stopper 13 for fixing these electric wires 11 to the housing 10,
It consists of a metal fitting 14 for holding the electric wire 11 with a screw 15.

The housing 10 that requires some kind of electrical connection is
An electric wire 11 such as a cable from the outside is connected to the terminal 12 through the input groove. Electric wire 1 of this cable etc.
1 passes through the wire stopper 13 so that it does not come off the groove, and is held and fixed by the metal fitting 14 with the screw 15.

However, in this telephone/intercom wire retaining structure, since the wire retainer 13 is made of resin, there is a gap 16 through which the electric wire 11 such as a cable can pass, so when the housing 10 is moved, etc. There was a problem that there was a risk that the wire might come off from the wire stopper 13.

In addition, if the wire stopper 13 is composed of a separate part, that is, a metal fitting, the metal fitting must be removed every time the electric wire 11 such as a cable is passed through, which is not only time-consuming but also requires the use of screws and metal fittings. However, there are disadvantages in that the number of parts increases, which ultimately increases the price. Moreover, if the wire stopper 13 is made of a separate component, that is, a metal fitting, there is a problem in that the electric wire 11 and the metal fitting rub against each other due to vibration, and in the worst case, there is a risk of disconnection or short circuit.

[Purpose of the invention] The present invention was made to solve the above-mentioned difficulties, and is to provide a telephone/intercom that can always elastically hold the input/output wiring of the telephone/intercom and securely fix it. The purpose is to provide a wiring fastening structure.

[Means for solving the problems of the invention] In order to achieve the above objectives, the telephone of the invention
According to the intercom wiring fixing structure, a wiring groove for storing input/output wiring for the telephone/intercom is provided on the casing of the telephone/intercom,
A stopper piece surrounding the wiring groove is formed of an elastic material from a part of the casing.

[Embodiments of the invention] Preferred embodiments of the invention will be described below with reference to the drawings.

In the embodiments shown in FIGS. 1 and 2, the telephone/intercom wire retaining structure of the present invention has a wiring groove 2 for storing wires 1 such as cables, cords, electric wires, etc. for inputting/outputting the telephone/intercom.
A terminal 5 for connecting wiring 1 such as a cable, cord, or electric wire is provided on the housing 3 of the telephone/intercom, and a stopper piece 4 surrounding the wiring groove 2 is integrally formed with a part of the housing 3 using an elastic material. It was formed.
In the illustrated embodiment, the wiring trench 2 has a substantially rectangular cross section. A stopper piece 4 formed of an elastic material from a part of the casing 3 is composed of pieces 4a and 4b so as to surround the wiring groove 2, and the piece 4a contacts the casing surface 3a forming the wiring groove 2 due to its elasticity. ing. It is preferable that the housing 3 of this telephone/intercom and the stopper piece 4 formed by a part thereof be made of plastic as an elastic body. However, if the housing 3 is made of sheet metal, etc., as long as the sheet metal has sufficient elasticity (for example, steel such as stainless steel), the stopper piece 4
can be integrally molded with the housing 3 from sheet metal or the like.

[Operation of the invention] In the telephone/intercom wiring fixing structure configured in this way, the wiring 1 of cables, cords, electric wires, etc. from the outside is routed through the wiring groove 2 of the telephone/intercom housing 3 that requires electrical connection. Connected to terminal 5. The wiring 1 such as a cable, cord, electric wire, etc. is inserted into the stopper piece 4 and fixed so as not to come off from the wiring groove 2.

When the wiring 1 such as a cable, cord, electric wire, etc. is inserted, the stopper piece 4 swings to the position shown by the dotted line in Fig. 3 due to its own elasticity, and after the wiring 1 has passed, it moves to the position shown by the solid line in the figure. Even if the housing 3 is moved to return to its original position, the wiring 1 will not come off the stopper piece 4.

[Effects of the invention] As is clear from the above embodiments, according to the telephone/intercom wire fixing structure of the present invention, the wiring groove for storing the input/output wires for the telephone/intercom is connected to the casing of the telephone/intercom. The stopper piece that is placed on the body and surrounds the wiring groove is made of an elastic material from a part of the housing, so that the wiring will not come off even if the housing is moved, and the wiring can be fixed without requiring a large number of parts. It can be held elastically and securely fixed at all times.
