Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a joint box for telephones.

[Background technology]

Due to the increasing frequency of telephone use, only one telephone is installed in one room.
We are moving away from one machine per room or one per person. Families often switch from traditional telephones to home telephones. For this reason, it is necessary to branch or extend the indoor wiring to a slave unit or the like from the middle of the indoor wiring. A telephone joint box is used for connection during branching and extension. The telephone joint box can be attached to construction materials. “Telephone joint boxes would be convenient if they could be used with both existing wiring in construction materials and newly installed wiring.

[Purpose of the invention]

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a telephone joint box that can be used for both post-installation and pre-installation of wiring.

[Disclosure of the invention]

In order to achieve the above object, the present invention provides a box-shaped body having a terminal section on the top surface and an open bottom surface for connecting telephone wiring; and a box-shaped cover superimposed on the top surface of the body so as to cover the phone, the body and the cover both having a knockout on the side that serves as a cord insertion slot. This article focuses on a joint box for telephones that is characterized by:

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 show an embodiment of the telephone joint box of the present invention. As shown in the figure, this telephone joint box 1 includes a body 2 and a cover 3.

The body 2 has a box shape with an open bottom, and a knockout 24 serving as a cord insertion opening 25 is provided on the side surface thereof. Approximately in the center of the top surface is provided an opening 6 for taking out a cord, which is connected to the cord insertion opening 25.

On the outside of the top surface, terminal portions 7 are provided on both sides of the opening 6 for taking out the cord. The terminal section 7 includes a terminal plate 8 that is attached and fixed to the body 2, a washer 9 that holds down the cord, and a terminal screw 10 that is screwed into the terminal plate 8 through the washer 9 and around which the cord is wound. Each terminal portion 7 is separated by an insulating wall 11 to ensure mutual insulation.

Fixing holes 12 are provided at the four corners of the top surface for fixing screws (wood screws or the like are used, but not limited thereto) for attaching the body 2 to construction materials or the like. The upper surface is also provided with a fitting claw 13 for attaching and fixing the cover 3 to the body 2, and a removal groove 14 used for removing the cover 3 from the body 2 as necessary. To remove the cover 3 from the body 2, use its removal groove 14.
You can insert the tip of a flathead screwdriver into the hole and lift it up.

The cover 3 is box-shaped with an open bottom, and a knockout 34 serving as a cord insertion opening 35 is formed on the side surface thereof. Although not shown, a fitting pawl that fits with the fitting pawl 13 is formed on the inner surface of the cover 3.

When using this telephone joint box 1 to connect newly installed wiring, etc., or when connecting the telephone joint box 1 before attaching it to construction materials, etc., use the knockout 2 of the body 2. The cord insertion opening 25 is formed by punching out the cord. This cord insertion slot 25
Telephone wiring, for example, outside line 15 and indoor line 16
are inserted into the inside of the body 2, guided through the opening 6 for cord extraction to the terminal portion 7, and connected. After completing the wiring, the body 2 is attached to construction materials, etc., and then the cover 3 is superimposed on the upper surface of the body 2 and fixed to the body 2. In this way, the wiring does not need to be raised from the surface of the construction material, so the appearance will not be degraded. In the above case, the cord insertion slot 35 is inserted into the knockout 34 of the cover 3.
However, the appearance is not good because the wiring needs to be raised from the construction surface.

When making a new connection to wiring that has already been connected with this telephone joint box 1, or when connecting the telephone joint box 1 after it has been attached to construction materials, etc., the cover 3 A cord insertion opening 35 is formed by punching out the knockout 34. telephone wiring,
For example, the outside WA 15 and the indoor line 16 are directly led to the terminal section 7 and connected. Thereafter, the outside wire 15 and the indoor wire 16 are fitted into the cord insertion opening 35, respectively, and the cover 3 is superimposed on the upper surface of the body 2. In this way, it is possible to connect the wires without removing the body 2 attached to the construction material, etc., thereby saving time and effort. In the above case, the cord insertion opening 25 may be formed by the knockout 24 of the body 2, but this requires removing the body 2 from the construction surface, which takes time and effort.

The telephone joint box of the present invention is not limited to the above-mentioned embodiments, and there are no particular limitations on the form or number of the terminal portions. Telephone wiring is not limited to outside lines and indoor lines, but may be other lines. It can be used not only to connect outside lines and indoor lines, but also to connect indoor lines. The number of knockouts provided on the body and cover is not particularly limited, but it is convenient if there are knockouts on two or four sides. Further, when the knockout is used as a cord insertion port, it is more convenient to have openings on the side where the body is attached to construction materials and the like, and the side where the cover is attached to the body, but this is not restrictive. There are no particular limitations on the means for attaching the body to construction materials or the like, and the means for attaching and removing the cover to the body.

[Effect of revelation]

As described above, the telephone joint box of the present invention is provided with a knockout that serves as a cord insertion port on both the body and the cover, so it can be used for both retrofitting and pre-fitting for wiring.
