[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 retrofitting and pre-attaching devices to wiring.

[Disclosure of the invention]

In order to achieve the above-mentioned object, the present invention provides a base-shaped body with a terminal portion provided on the upper surface for connecting a telephone wire, and a body with an open bottom surface so that the terminal portion can be connected to the terminal portion. A joint box for a telephone equipped with a box-shaped cover for covering the telephone, characterized in that the cover is provided with a knockout serving as a wire insertion hole on the side thereof, and is placed over the body so as to cover the body. The main point is the joint box.

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

1 to 4 show an embodiment of the present invention. As shown in the figures, a joint box 1 for a telephone according to the present invention has the following features:
It includes a body 2 and a cover 3.

The body 2 is formed in the shape of a table, and a terminal portion 7 for connecting a telephone wire is provided on the upper surface of the body 2, so that the telephone wire is directly led to the upper surface. The terminal portion 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 wound around the cord and fastened to the terminal plate 8 through the washer 9. Each terminal portion 7 is separated by an insulating wall 11 to ensure mutual insulation. The four corners of the top surface of the body 2 are covered with construction materials 2.
A fixing hole 12 (for example, a screw 18 or the like can be used, but is not limited to this) is provided for attaching the device to the device. A fitting claw (locking claw) 13 for attaching and fixing the cover 3 to the body 2 is also provided on the top surface.
A removal groove 14 is provided for use in removing the cover 3 from the body 2 if necessary. To remove the cover 3 from the body 2, insert the tip of a flathead screwdriver into the hole a14 and pull it up.

As in this embodiment, the terminal portion 7 is provided with a terminal plate 8 having a certain length, and terminal screws 10 and 10 are respectively fastened to both longitudinal ends of the terminal plate 8. This is useful when branching off from the middle of already installed telephone wires. In this case, the terminal board 8
Arrange the telephone joint box so that the length direction is along the wiring direction of the telephone wire, connect the - side telephone wire to one terminal screw 10, and connect the - side telephone wire to the other terminal screw 10. Connect it to one terminal screw 10. In this way, there is no room for the telephone wire (but since the terminal board compensates for the length in the wiring direction, it is possible to branch out and connect the original wire. However, the terminal section
The structure may not be like this, and is not limited to the structure of this embodiment.

The terminal plate 8 is press-fitted, or the protrusion 19 described below is
If it is fixed to the rib body 2 by being prevented from being removed, there is no need to use separate parts such as caulking rivets or screws. For example, as shown in FIGS. 5 and 7, in the above embodiment, the terminal plate 8 is a flat plate, and the insulating walls 11 are press-fitted between the insulating walls 11. A convex portion 19 is formed which gradually swells and swells sharply on the lower side. The terminal plate 8 is press-fitted so as to ride over the convex portion 19 from the gently raised side. The terminal plate 8 is locked to the sharply raised side of the convex portion 19 and is prevented from coming out from between the insulating walls 11. In body 2,
A cylinder 20 is formed with the end face facing upward, and the end face of this cylinder 20 receives the terminal plate 8 to fix the height, and the inside (hollow part) of the cylinder 20 is located on the tip side of the terminal screw 10. The receiver is inserted to create an escape for the terminal screw 10.

A shape other than a cylinder may be formed as long as a clearance for the terminal screw can be created. Or terminal board 8
may be U-shaped as shown in FIGS. 6 and 8. In this case, the U-shaped tip of the terminal plate 8 hits the body 2 to determine the height, and the terminal screws are fastened to the U-shaped holes. The tip end side of the terminal screw 10 is inserted into the inside of the U-shape to create an escape for the terminal screw 10. In addition, when the terminal plate 8 is U-shaped, it may be press-fitted into a recess provided in the body so that the opposite side of the U-shape receives force inward. but,
The method of fixing the terminal plate 8 to the body 2 is not limited to press fitting.

The shape of the terminal board is not limited to the above.

The cover 3 has a box shape with an open bottom, and a knockout 34 serving as a wire insertion opening 35 is formed on the side surface thereof. This knockout 34 can be installed in various ways, but if it is provided on four sides of the cover 3, the electric wire can be taken out in either the vertical (or front/back) or left/right direction. A fitting claw (locking claw) 13 of the body 2 is provided on the inner surface of the cover 3.
A fitting claw (latching claw) 17 that fits (latches onto) is formed. The cover 3 has a shape and size that covers the body 2.

The cover 3 is placed over the body 2 so as to cover the body 2. Therefore, the telephone joint box of the present invention can be used regardless of whether a device is attached to the wiring afterwards or first.
Regardless of whether it is used for telephone wires that have already been wired or for newly wired telephone wires, the wire insertion port 35 can be formed by tearing the knockout 34 of the cover 3. If a telephone wire is inserted from 35, it can be led directly to the terminal section.

When this telephone joint box 1 is used to connect newly wired electric wires, etc., when connecting the telephone joint box 1 before attaching it to construction material 21, etc., the upper surface of the body 2 Telephone wires, for example, an outside wire 15 and an indoor wire 16, are led directly to the terminal and connected to the terminal portion, and the body 2 is attached to a construction material 21 using wood screws 18 or the like.

On the other hand, after tearing the knockout 34 of the cover 3 and forming the wire insertion opening 35, the terminal portion 7 is covered and the outer yA1 is
5 and the indoor wire 16 are fitted into the wire insertion port 35, and the cover 3 is placed over the body 2 so as to cover the body 2 and fixed to the body 2. In this way, there is no need to raise the telephone wires from the surface of the construction material, so the appearance does not deteriorate.

When using this telephone joint box 1 to take a branch from a telephone wire that has already been wired, or when making a new connection to a wire that has already been connected using this telephone joint box 1, etc. When connecting the telephone joint box 1 to a construction material 21 or the like and then connecting the wires, the knockout 34 of the cover 3 is broken to form the wire insertion opening 35. The body 2 is attached to construction materials 21 or the like using wood screws 18 or the like. Telephone wires, for example, an outside line 15 and an indoor line 16, are led directly to the terminal portion 7 and connected. After that, the outside wire 15 and the indoor wire 16 are respectively fitted into the wire insertion opening 35, and the cover 3 is placed over the body 2 so as to cover it and fixed to the body 2.

In this way, the wires can be connected without removing the body 2 attached to the construction material 21 or the like. Further, since there is no need to raise telephone wires from the surface of construction materials, the appearance does not deteriorate.

The telephone joint box of this invention has a knockout that serves as a wire insertion hole only on the cover.
In order to accommodate the retrofitting and advance attachment of equipment to wiring,
The number of knockouts is reduced compared to those with knockouts on both the body and cover. Knockouts have low strength and are unsightly, so by reducing knockouts, the telephone joint box of the present invention has improved strength and is less unsightly. Moreover, the telephone joint box of this invention is
The cover is provided with a knockout that serves as a wire insertion port, and this cover can be placed over the body to cover it, so it can be used for both retrofitting and pre-installation of wiring. In addition, it can be used with both existing wiring and newly installed wiring, and can be used both before and after it is attached to construction materials.

The telephone joint box of the present invention is not limited to the above embodiments. The cover may not be fixed to the body, but may be fixed to something else (eg, construction material, etc.). There are no particular limitations on the form, number, etc. of the terminal portions. Telephone wires are not limited to outside lines and indoor lines, and may be other lines. Used only to connect outside lines and indoor lines. (It is also used for connecting indoor wires, etc.) When using a knockout as an electric wire insertion port, it is more convenient to have an opening on the side where the cover is attached to construction materials, etc. There are no particular limitations on the means for attaching the body to construction materials, the means for attaching/removing the cover to the body, etc.
