Description

[Detailed description of the invention] (Field of industrial application) This invention relates to terminals for telephone lines for meetings used during telephone line construction, and many terminals are provided in the middle of telephone cables. It is installed inside the cable connection terminal box and is used for construction work meetings.

(Prior Art) Conventionally, this type of meeting has been conducted by connecting a handset to a specified line in the telephone cable, that is, a meeting circuit, but there is no special terminal provided for this purpose. In order to connect the handset, it is necessary to expose the core wire and connect it after finding the meeting circuit, and furthermore, at the end of the construction, after removing the handset, the exposed core wire must be insulated, moisture-proof, etc. There were inconveniences such as the need for additional treatment.

(Problems to be Solved by the Present Invention) The purpose of the present invention is to provide a pair of terminal blocks that are easy to add and can be connected to a meeting circuit and installed inside a connecting terminal box, in order to eliminate the inconveniences of the conventional method. There is a particular thing.

(Means for Solving the Problems) The present invention has a hanging wire holding groove for holding a hanging wire of an overhead cable, etc. on one surface of a block formed by overlapping block pieces A and B with grooves. The inner hole formed by the groove accommodates the connecting portion between the other end of the pair of terminals, each of which has one end protruding outside the block, and the electric wire, and is made of a plastic and disconnectable material. The main feature of the block is a pair of terminal blocks, characterized in that a mixture of the above-mentioned terminals is sealed, and two electric wires, one for inlet and one for outlet, are connected to each of the terminals.

(Function) The pair of terminal blocks configured as described above can be easily inserted into the meeting line and installed inside the connection terminal box.

(Example) Embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, grooves are bored in block piece A1 made of an insulating material as shown in the figure, and terminals 3 and 4 are provided therein.

Insulated wires 5 and 8 are attached to the terminal 3, and insulated wires 6 and 7 are attached to the terminal 4 by, for example, solder, and the insulated wires are drawn out of the block.

For example, a resin dip part 2 is attached to the tips of the terminals 3 and 4 to prevent the tips of the terminals from coming into contact with and damaging the insulation coating of other circuits during construction.
0,20' are provided.

The block A1 is further provided with a hole 9 and a cut portion 11 formed on one side.

2 is a block piece B which is overlapped with the block piece A1 to form the whole block, and has a groove, a hole 10, a cut part 11', and an injection port 1 corresponding to the block piece A1.
2 is provided.

Next, when block piece A1 and block piece B2 are superimposed and firmly fixed, the grooves provided in both blocks form holes. A mixture that maintains plasticity and has insulation and moisture-proofing properties is injected into the pores through the injection port 12.

Further, the cut portions 11 and 11' form a V-shaped groove.

The terminal block thus formed is placed inside a connecting terminal box 17 provided in the middle of the cable 14, as shown in FIG. Attachment: The insulated wires 5, 6 and 7, 8 are connected to the cable meeting lines 15, 15' and 19, 19' using a connector 14 or the like.

(Effect of the invention) In other words, the present invention connects the handset, which is normally carried by construction workers, to terminal 3,
4, a communication channel for meetings is immediately established.

Moreover, when according to the present invention, the meeting circuit 16,1
6' is not cut to form a communication path for a meeting, but is extended further back through 19 and 19', passing through a number of terminal blocks of the present invention along the way, so construction over a long section is required. This has the effect of ensuring a means of communication for a large number of workers, and furthermore, the fact that the plastic material is sealed in block pieces A and B prevents them from being exposed to cold, hot air, and vibrations for many years in an overhead state. This has the effect of protecting against damage such as wire breakage and terminal corrosion due to
