Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable connecting device that can be used in a connection branching operation.

[0002]

2. Description of the Related Art Conventionally, the work of branching a trunk cable for supplying electricity to each floor of a building and the connection of cables cut at a construction site or the like are performed by directly connecting the cables or by using a plug-in connector or the like. The connection has been made using a connection device such as a blade-shaped connection terminal.

[0003] In a method of directly connecting cables, a sheath and an insulator of the cable are shaved, the conductive wires are exposed, the conductive wires are entangled with each other, and an insulating tape is wound.
This is a method in which an insulating tape is wound around each conductive wire and then the entire surface is wound with the insulating tape.

[0004] A conventional plug-in connector conventionally used is one in which male and female plugs are attached to respective cables, and the male and female plugs are fitted and connected. Although the cost of this plug-in connector is slightly higher, it can be connected simply by inserting it, and it is highly reliable because it is hard to pull out.

[0005] In addition, in the case of a generally used connection terminal in the form of a vane plate, a connection terminal having a semicircular cross section obtained by dividing a columnar portion into two in the axial direction is attached to each cable, and a cracked portion is formed. These are joined and connected. This blade-shaped connection terminal is characterized by being less expensive than the above-described plug-in connector and being easily insulated.

[0006]

However, the method of directly connecting the cables has a problem in that the cables are easily disconnected when pulled because they are connected only by tape. In addition, if the tape is peeled, it is not preferable because the leakage or short circuit is easily caused.

When any of the above-mentioned connecting devices is attached to the cable, the sheath and the insulator of the cable must be slipped to a certain extent, and the conductive wire must be exposed and attached to the connecting device.

If the conductive wire is damaged when slipping the cable sheath and the insulator, a load is applied to the damaged portion more than other portions, which is dangerous. Therefore, this operation is performed carefully and takes a very long time.

Further, if the conductive wire is damaged, the cable must be cut to that point and the sheath and insulator of the cable must be slipped again to some extent. Is also wasted.

[0010] In addition, when the sheath and the insulator of the cable are slipped, scraped sheath and debris of the insulator are generated.
There was also a problem that the work site became dirty.

In addition, since the connecting operation particularly pulls or twists the cable, the conductive wire in the cable may be cut. At that time, there has been a problem that it has been difficult to specify a place where the insulation has been performed in the related art, so that the connecting and branching work is delayed or the whole work is hindered.

[0012]

In order to solve the above-mentioned problems, a cable connector according to the present invention comprises a plurality of connecting pins inserted into the end of each conductive wire of a cable having a plurality of conductive wires; An insulating grip for connecting and holding the connection pins, an insertion aid inserted between the conductive wires of the cable,
A clamp is attached to the outer periphery of the end of the cable into which the connection pin has been inserted. The parts are arranged substantially in parallel at a predetermined interval, the insertion aid includes a partition member composed of one or more partition plates and a bottom plate fixed to the base end of the partition member, and the partition plates are radially arranged. They are arranged at substantially equal angles, holes are formed in the bottom plate through which the connection pins penetrate, holes in the bottom plate are formed one by one between the partition plates, and the ends of the conductive wires when the insertion aid is inserted into the cable It is characterized by being on an extension of the part.

[0013] Further, a guard piece is provided on a partition plate of the insertion aid.

Further, the connection pin and the grip portion can be separated.

Further, a confirmation lamp is provided on the grip portion.

[0016] One end of a cable connector is attached to the base end of the connector, the lighting fixture, the motor, or the switch.
It is characterized by having approximately half.
