According to the cabtire cable branching connector of the present invention, the following effects can be obtained. That is, when two cabtire cables are connected and a branch line is branched from the connection position, for example, when a branch line (slave line) is drawn from the cabtire cable constituting the control bus,
The cabtire cable is cut right and left at the branch line withdrawal position, and an end unit is attached to each cable end. Attachment of the end unit to these cable ends performs the same connection work for both the cut left and right cable ends, and a plurality of core wires are stripped from the cut left and right cable ends. Each stripped core wire is inserted into a core wire insertion hole corresponding to the end body of each end unit. When inserting the core wire, a color (for example, black, white, red, blue, yellow) is provided near the core wire insertion hole of the end body in correspondence with the core wire,
Alternatively, if identification means such as attaching numbers or symbols is provided, erroneous insertion of the core wire can be avoided. Each core wire inserted into each core wire insertion hole as described above is pressed and held by the inner wall of the core wire insertion hole by the core wire pressing piece. In addition, when each core wire insertion hole is formed so as to penetrate and the core wire can be penetrated, insertion can be confirmed because the core wire has penetrated, and a cutting tool (for example, a nipper) can be inserted at the end of the core wire at the penetration position. By cutting, the ends of the core wire can be aligned.

Then, the end of the cabtire cable is held by the end unit by attaching the cover to the end body.

Next, the two cabtire cables each having the end unit attached thereto are brought into abutment with the positions of the respective core wires corresponding to each other, and held by the holding unit of the branching unit.

In holding the end unit with respect to the branching unit, by providing a restricting portion or restricting means for restricting the mounting direction of the two end units to one, each of the two end units is provided. The core wire can be prevented from being erroneously connected. In this case, if the insertion position of the core wire is the same for both end units, the front and back of one end unit are inverted and held by the branch unit, so that each core wire of the end unit corresponds to each other. I do. In addition, since the press-fit terminal insertion hole of the core wire insertion hole penetrates the front and back to enable insertion from both surfaces, the end unit can be held upside down.

When a partition is interposed between two opposing end units facing each other, each core wire on the opposing side and the end of each adjacent core wire can be insulated.

When the two end units are held by the branch unit as described above, each press contact terminal of the branch unit is simultaneously inserted into the insertion hole of the corresponding press terminal of each end unit. Then, the inner core wires are pressed and electrically connected. As a result, the two cabtire cables and the branch terminal are electrically connected, and the branch line can be pulled out from the branch terminal.

Further, by inserting the branch connection connector into the branch terminal, a branch line (slave line) can be drawn from the cabtire cable constituting the control bus.

If the ends of the above-mentioned branch terminals are formed in a bifurcated insertion groove, the terminals on the branch connection connector side can be formed in a plate-like shape, thereby preventing the mutual terminals from becoming complicated.

Further, for example, when the holder for the cabtire cable branching connector described above is attached to a holder having a U-shaped cross section from the end unit side and fixed to the branching unit, the holder becomes This prevents the end unit from being pulled out of the branch unit.

Further, by attaching the holder to a fixed portion such as a fixed wall, the cabtire cable branching connector can be mounted to the fixed portion.

[0023]

According to the cabtire cable branching connector of the present invention, when a branch line is pulled out from the cabtire cable, the preparation work for the cabtire cable is to cut the cable and strip the core wire.
The core wire can be used in a coated state without having to remove the coating, so that the preparation operation is simple.

Further, since the core wire can be attached to the end unit only by inserting the core wire into the core wire insertion hole of the end body, the operation is simple, and each core wire is distinguished when inserting the core wire. With the identification means for performing the above, erroneous insertion of the core wire, that is, erroneous connection of the core wire, can be obtained, and a reliable connection can be obtained.

Further, the electrical connection between the two cabtire cables and the branch terminal can be easily achieved by mounting the two end units to the branch unit.
The operation of forming a branch line from the cabtire cable is simple.

Further, when the two end units are mounted on the branching unit, a restricting portion or a restricting means for restricting the mounting direction of the two end units to one is provided. The core wires of the unit are not erroneously connected, and the core wires of the separated cabtire cable can be securely connected to the original connection state.

Further, since the branch terminal of the branch unit is formed in a bifurcated insertion groove, the terminal of the branch connection connector inserted therein can be formed in a plate shape, thereby preventing the mutual terminal structure from becoming complicated. Thus, mutual terminals can be formed with a simple terminal structure.

Further, when the two end units and the branching unit are attached, they are fixed by a predetermined fixing means (for example, a patching fixing structure). By attaching a letter-shaped holder and fixing it to the branching unit, this holder will prevent removal from the end unit, and by attaching the holder to the fixed part, attach the cabtire cable branching connector to the fixed part Can be.
