Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cable branching terminal used when branching a plurality of cables from a single plate conductor.

[Prior Art] When supplying power to multiple points within a limited space, for example when supplying power to multiple light bulbs, it is often necessary to connect multiple branch cables to the main cable. be. However, conventionally, branch cables generally have to be connected one by one using screws or the like, and when a large number of branch cables are used, workability becomes significantly worse. Furthermore, in narrow spaces, it is desirable to connect the branch cables in a desired direction.

[Purpose of the invention] The purpose of the invention is to provide a cable branching system that can easily connect a large number of branch cables to a plate conductor, which is a main conductor, with low electrical resistance, and that can direct the branch cables in multiple directions. The purpose is to provide terminals.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
A cable branching terminal for branching a plurality of branch cables from a plate conductor, which is a main conductor, with two conductive cables attached to a hole provided in the plate conductor by overlapping them with bolts and nuts. It has clamping members, the contact surfaces of these clamping members with the plate conductor are flat, each of these clamping members has an arcuate cross section, and the two clamping members together form a substantially elliptical cylindrical shape. protruding connecting portions in multiple directions, inserting the end of the branch cable into these connecting portions,
The cable branch terminal is characterized in that the bolt/nut tightens the end of the branch cable.

[Embodiments of the invention] The invention will be described in detail based on illustrated embodiments.

In FIG. 1, 1 is a plate conductor such as a bus bar, and a branch terminal 2 is attached to the tip of this plate conductor 1. The main members constituting this branching terminal 2 are two conductive metal clamping members 3 and 4, which are stacked almost symmetrically and have a hole 5 drilled in the center and a plate member. A bolt 7 is inserted into the hole 6 of the conductor 1, and is fixed to the plate conductor 1 with a nut 8, so that the clamping members 3 and 4 can be fastened together. In addition, the plate conductor 1
The hole 6 is a square hole, and the bolt 7 is a square root/round head bolt. The clamping members 3 and 4 are disk-shaped with a hole 5 in the center, have a flat part for contacting the plate conductor 1, and have connecting parts 9 protruding in a cross shape on all sides. The connecting portions 9 each have an arcuate cross section so that a substantially elliptical cylinder is formed when combined with the connecting portions 9 of the opposing clamping members 4 and 3. Note that a disc spring 10 is interposed between the nut 8 and the clamping member 3 to prevent the nut 8 from loosening.

In use, the nuts 8 are loosened to widen the connections 9 of the clamping members 3, 4. At this time, since the hole 6 of the plate conductor 1 is rectangular, the bolt 7 can be loosened by simply turning the nut 8 without fixing the head of the bolt 7. Note that in actual work, the space between the connecting portions 9 is often widened appropriately, and this widening work is not necessary. Then, by inserting the exposed core wire portions 12 of the branch cable 11 between the four sets of connection portions 9 and tightening the nuts 8, the four core wire portions 12 between the connection portions 9 are fixed in one operation. That will happen.

In the case of the embodiment shown in FIG. 1, the branch cable 11 is connected in parallel and perpendicular directions to the plate conductor 1, but as shown in FIG.
If the branch cable 11 is fixed to the plate conductor 1 in an oblique direction, the branch cable 11 can be pulled out in an oblique direction. Further, by arranging a plurality of branching terminals 2 on the plate conductor 1, more branch cables 11 can be branched from the same plate conductor 1.

[Effects of the invention] As explained above, the cable branching terminal according to the invention can connect a plurality of branch cables from a plate conductor, which is a main conductor, with one connection terminal in one operation. It is possible to select the branching direction as appropriate.
