Description

Wiring branch device

The present invention relates to a wiring branching device.

In various devices that use electricity, wiring, bus bars, etc. can be used to connect circuits composed of multiple components. The connection between bus bars can be done using bolts and nuts, and the connection of wires can be done directly between wires, but multiple wires can be connected using connectors.

Busbars and wiring can be connected in a variety of ways. For example, you can connect ring terminals to wiring using fastening bolts and fastening nuts that penetrate the bus bar.

Recently, a method of fixing a clinching bolt to a bus bar, hanging a ring terminal on it, and fastening a nut to the clinching bolt to secure the ring terminal is used. This configuration is shown in Figures 1 and 2.

According to these drawings, the bus bar 1 made of a conductive material may have a predetermined thickness and width. A clinching bolt (3) may be press-fitted and fixed to one side of the bus bar (1). In order to install the clinching bolt 3, a through hole having an inner diameter smaller than the diameter of the clinching bolt 3 may be formed in the bus bar 1. A male thread may be formed on the outer surface of the clinching bolt (3).

There is a nut (5) fastened to the clinching bolt (3). The nut (5) is fastened to the clinching bolt (3) to electrically connect the ring terminal (9) to the bus bar (1). A wire 7 is connected to the ring terminal 9, so that the bus bar 1 and the wire 7 are electrically connected to allow branching of the circuit.

With the ring terminal 9 seated on the bus bar 1 so that the clinching bolt 3 penetrates the center of the ring terminal 9 to which the wiring 7 is connected, the nut 5 is tightened with the clean nut 5. When fastened to the ching bolt (3), the ring terminal (9) can be brought into close contact with the bus bar (1) by the pressing plate (6) integral with the nut (5). In this way, sufficient electrical connection can be made between the bus bar (1) and the ring terminal (9).

However, in the prior art having this configuration, in order to couple and separate the bus bar (1) and the wiring (7), an operation for coupling and separating the clinching bolt (3) and the nut (5) is required. do. In particular, it is possible to fasten and separate the nut 5 from the clinching bolt 3 only by using a separate tool, which causes a problem in that the number of workers is relatively increased.

Additionally, there is a problem in that the number of parts used to branch the wiring 7 from the bus bar 1 is relatively large.

In addition, since the clinching bolt 3 protrudes above the surface of the bus bar 1, there are problems such as interference with components around the bus bar 1 and securing an insulation distance.
