Description

[Detailed description of the invention]

[0001]

Industrial Applicability The present invention is applicable to a case where a telephone terminal board needs to be replaced due to corrosion or the like, without replacing an existing telephone cable (a cable in which a plurality of insulated cored wires are bundled together), and BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instantaneous interruption-free substitute terminal plate that can be replaced without instantaneously interrupting a telephone cable.

[0002]

2. Description of the Related Art A telephone cable is used for a building requiring a large number of telephone lines, and a telephone terminal board such as a 10L terminal is used for processing and connecting the core of the cable terminal. . If such a telephone terminal plate is used for a long period of time, it may be corroded by moisture or the like, which may cause a failure of the telephone line.

Conventionally, when a telephone terminal plate is renewed, a telephone cable is newly provided, and a core wire of the new telephone cable is wired to the new telephone terminal plate. In an emergency, the telephone cable core was cut off, the corroded telephone terminal plate was removed, and then the new telephone terminal plate and the telephone cable core were manually connected.

[0004]

However, in such a conventional repair method, since the telephone cable is still usable, it is replaced with a new cable, so that the repair cost is very high. Also, in the case of emergency repair, the telephone line is disconnected during the period of manual connection, which causes a great deal of trouble for customers.

An object of the present invention is to provide a terminal plate for instantaneous interruption which enables replacement of a terminal plate without an instantaneous interruption and which allows a conventional cable to be used as it is without cutting a telephone cable. is there.

[0006]

For this purpose, the terminal plate for instantaneous interruption according to the present invention has a plurality of U-slit connection terminals on the primary side attached to one side of the main body and a U-slot connection terminal on the secondary side attached to the other side. The same number of the slit connection terminals as the primary side U-slit connection terminals were attached, and a space between each of the primary side U-slit connection terminal and the secondary side U-slit connection terminal was embedded in the main body. It was configured by connecting with electric wires.

[0007]

The instantaneous disconnection terminal board of the present invention can easily connect the U-slit connection terminal directly to the telephone cable core connected to the defective telephone terminal board. A temporary connection of the telephone line to both terminal strips can be created, so that subsequent disconnection of the telephone cable core on the side of the defective telephone terminal board will not break the telephone line. . Also, the telephone cable that is laid is used as it is.

[0008]

Embodiments of the present invention will be described below. FIG. 1 is a front view of an instantaneous interruption-free substitute terminal plate 1 of the embodiment, and FIG. 2 is a plan view. The instantaneous-interruption-replacement terminal plate A has a U-shaped cross section in which the central portion 2 of the main body 1 is concavely concave, and a screw hole 3 for mounting is formed therein.

Also, the primary side terminal portion 4 having a convex shape on one side is provided.
Has 10 U-slit connection terminals 5 in a substantially linear
Ten U-slit connection terminals 7 are similarly provided in the secondary terminal portion 6 having a convex shape on the opposite side via the central portion 2.

[0010] The U-slit connection terminals 5 and 7 are arranged such that each of the arrangements outside the primary terminal 4 is arranged outside the secondary terminal 6 and the arrangement inside the primary terminal 4. Are arranged inside the secondary terminal portion 6 and the electric wires 8
(Total of 20). Each of these electric wires 8 is buried in the main body of the terminal plate 1 and is protected from disconnection due to corrosion or the like.

Reference numeral 9 denotes a moisture-proof cover that covers the U-slit connection terminal 5 of the primary terminal portion 4, and reference numeral 10 denotes a moisture-proof cover that covers the U-slit connection terminal 7 of the secondary terminal portion 6.

Next, a case where the substitute terminal board A is replaced with a defective telephone terminal board B will be described. FIG. 3 is a front view in which the telephone terminal plate B is positioned above the substitute terminal plate A, and FIG. 4 is a plan view thereof. FIG. 5 is a front view of a state in which the substitute terminal plate A is mounted on the mounting plate C, and FIG. 6 is a plan view thereof. FIG. 7 is a diagram for explaining the operation of the U-slit connection terminal 5.

At the time of this replacement, first, the defective telephone terminal plate B is detached from the mounting plate C to which it is attached and floated.
The substitute terminal plate A is inserted, and the lower surface of the substitute terminal plate A is temporarily fixed to the mounting plate C with a double-sided adhesive tape (not shown) or the like. Fix to the mounting plate C.

As a result, the defective telephone terminal plate B is located at the central portion 2 of the upper surface of the substitute terminal plate A, and the telephone cable wired to the primary terminal 12 protruding from the main body 11 of the telephone terminal plate B. The core wire 13 is directly used as a substitute terminal plate A
To the U-slit connection terminal 5 of the primary-side terminal portion 4.

Further, the telephone cable core 15 wired to the secondary terminal 14 protruding from the main body 11 of the telephone terminal plate B is directly connected to the U-side of the secondary terminal portion 6 of the substitute terminal plate A.
Connect to slit connection terminal 7.

As shown in FIG. 7, the width of the slit 5a of the U-slit connection terminal 5 is set to be smaller than the diameter of the central conductor 13a of the core 13 as shown in FIG. That the slit 5a
When the core 13 is inserted into the center conductor 13a, the beam portion 5b cuts the insulating coating 13b of the core 13 and the center conductor 13a.
It is done by biting into. The same applies to the connection of the other core wire 15 to the U slit connection terminal 7.

As described above, the telephone cable cores 13 and 15 connected via the defective telephone terminal board B are similarly connected via the substitute terminal board A.

Then, after that, the telephone cable core 13 is cut off from the telephone terminal plate B near the U-slit connection terminal 5, and the telephone cable core 15 is similarly cut from the telephone connection terminal B near the U-slit connection terminal 7. Let go.

As described above, the telephone cable cores 13 and 15 can be switched from the state of being connected via the telephone terminal board B to the state of being connected via the substitute terminal board A without instantaneous interruption. .

Therefore, a situation in which the telephone line is disconnected during the switching operation during this time does not occur. The U-slit connection terminals 5 and 7 of the substitute terminal plate A are covered with moisture-proof covers 9 and 10 to prevent corrosion at the portions.

[0021]

[Effects of the Invention] From the above, according to the substitute terminal board of the present invention,
A defective telephone terminal board that has become defective due to corrosion or the like can be replaced with a substitute terminal board without replacing an existing telephone cable core wire and without instantaneously interrupting the telephone line.

Therefore, there is an advantage that the construction cost can be reduced, the construction operation and the confirmation test after the construction can be reduced, and the trouble for the customer can be reduced.
