JPS582117Y2 - External line terminal board for concealed wiring - Google Patents

Description

[Detailed description of the invention] The invention is an improvement of the outside line terminal board that connects the telephone cord and the indoor line (with regard to this, an improvement has been made so that this outside line terminal board can be used for hidden wiring).

Conventionally, when installing a telephone in a telephone subscriber's premises,
This is done by fixing the external line terminal board attached to the terminal of the indoor wiring to a suitable pole, etc. (with screws), and connecting the telephone cord to this. Concealed wiring is increasingly being used for telephone wiring for safety and aesthetic reasons.

Therefore, the conventional external line terminal board, which is used by being attached to a pillar, has become inconvenient both in terms of construction and aesthetics.

Therefore, the object of the present invention is to provide an outside line terminal board that is buried in a building and connects the hidden indoor line and the telephone cord.

An unconventional structure for achieving this purpose is to bury a box for pulling out and accommodating indoor wires inside a building, and fixing a protective plate covering it, while A through hole is formed in the protective plate in an arc shape through which the core wire of the telephone cord of the telephone to be placed is passed through the box, and a plurality of terminal boards are provided to connect the indoor wire pulled out into the box and the core wire. Attach the locking member to the back of the protective plate so that it is approximately equidistant from the arc-shaped through hole, and attach the locking member for fixing the telephone cord to the front of the protective plate (as you rub it, the locking member here) and a protective cover that covers and hides the through hole.

Hereinafter, the unconceived configuration will be explained in detail based on a specific example shown in FIG.

Inside the building 1 (this is used to pull out an indoor line (not shown) from a buried pipe or to pull out an indoor line 2 directly buried (this is a protective plate 4 equipped with a terminal board 6). Box 3 serves as a receiver for securing the building to Building 1.
is a rectangular (square, square, or circular) box made of a steel plate or the like, and on the top and bottom (a tongue piece 3a with screw holes for fixing the protective plate 4 with screws) is folded inward. On the other hand, there are indoor wires 2 on the top and bottom or left and right sides.
A hole 3b for drawing in is already drilled.

This box 3 is buried at a predetermined location within the building 1 when the building 1 is constructed or after its completion.

A protective plate 4 that is screwed to the box 3 and covers the box 3 has an indoor line 2 drawn into the box 3 and a telephone cord 5 of a telephone installed indoors on its back side.
While the required number of terminal boards 6 to connect the
A through hole 7 is bored through which the core wire 5a of the outer telephone string 5 can be drawn into the box 3.

The through hole 7 facilitates the introduction of the core wire 5a.
From the fixed position of the telephone string 5 to each terminal plate 6.・・・
・In order to clearly distinguish between shi and shi with almost equal distances, there is an arc-shaped elongated hole bored into n.

Normally, the core wires 5a of the telephone string 5 are exposed for the same length, so that each terminal plate 6. If the distances to... are not equal, the core wires 5a will overlap, which is inconvenient.

Furthermore, on the surface side of the protective plate 4, the telephone cord 5 is fixed at the terminal part of the cord so that the core wire 5a of the terminal plate 6 portion does not break when the telephone cord 5 is pulled. A locking member 8 is installed.

This locking member 8 is made of a metal piece having one end to which the protective plate 4f is screwed, and the other end in the shape of a half-split tube to firmly grip the telephone string 5 so as to tighten it.

This locking member 8 made of a metal piece is often attached to the end portion of the telephone string 5 in advance.

In addition, even if such means are not used, the surface of the protection plate 4 ( The three locking pieces facing each other may be provided in a protruding manner so that the end of the telephone string 5 can be firmly held.

Moreover, the locking member 8 is provided on the surface side of the protection plate 4.
A protective cover 9 is attached to cover and protect the through hole I.

This is a long hole 10 formed in the protective plate 4 by a tongue piece 9a that is folded back outward from a part of the bottom edge of the box-shaped protective cover 9, which is bent so that the telephone string 5 can be passed from the side. It is designed to be installed by inserting it inside.

In this way, the terminal board 6 and the protective cover 9 are provided, and the locking member 8 (
Protective plate 4 that has been twisted to secure the telephone cord 5
is provided with a through hole 11 through which the upper and lower screws pass,
This protective plate 4 is fixed to the box 3 with screws.

Therefore, when the telephone is not installed at the same time as the indoor wiring, the indoor wiring 2 must be installed in the box 3 buried in the 1st floor of the building.
Pull out the terminal part of the box, connect this indoor wire 2 to the terminal board 6 on the back of the protection plate 4, and then place the protection plate 4 on the box 3 by fixing it.

Then, when installing a new telephone, the protective plate 4 can be removed from the box 3, and the locking member 8 attached to the terminal part of the telephone string 5 can be screwed to the protective plate 4, or the protective plate After firmly gripping the telephone string 5 with the locking member 8I attached to the locking member 8I, the core wire 5a of the telephone string 5 is passed through the through hole 7 and introduced into the back side of the protection plate 4.
Connect each to the terminal board 6 on the back side.

Then, after fixing the protection plate 4 to the box 3 again,
Once the protective cover 9 is attached, the construction is completed.

Needless to say, first, the telephone cord 5 is attached to the protective plate 4, and then the indoor wire 2 drawn out into the box 3 is connected to the terminal plate 6 (or it may be done).

Thus, it is possible to provide an outside line terminal board for connecting a hidden indoor line and a telephone cord inside a building.

Furthermore, connections between the indoor line and one outside line terminal and between the telephone cord and the other outside line terminal can be made easy and strong.

Moreover, the installation appearance is simple and beautiful.

Claims (1)

[Scope of Claim for Utility Model Registration] A box for pulling out and accommodating indoor cables buried in a building is buried in the building, and a protective plate covering the box is fixed, while a telephone set installed indoors is A through hole is drilled in the protection plate in an arc shape through which the core wire of the telephone cord passes through the box, and a plurality of terminal plates are inserted in the box to connect the indoor wire pulled out and the core wire in the arc shape. Attach it to the back of the protection plate so that it is approximately equidistant from the through hole, and attach it to the front of the protection plate (to attach the locking member for fixing the telephone cord).
