Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting part for branching and connecting electric wires constituting an automobile wire harness.

[0002]

[Prior art]

 Conventionally, the mutual branch connection of the electric wires constituting the automobile wire harness has been performed by the following means, for example. 1) As shown in FIG. 4, the coating of the electric wire 1a is peeled off to expose the core wire, the branch wire 1b is connected thereto by the connection terminal 2, and then the insulating tape 3 is wound to protect the insulation ( Splice connection method). 2) When the twisted wires are interconnected in the middle, the above splice connection method cannot be used. Therefore, for example, when connecting four units 4 as shown in FIG. 5 with a twist wire 5, as shown in FIG. 6, a bus bar 6 having four connection ends and a twist wire 5 are provided. A joint connector in which the four terminals 7 crimped and connected by the connector 8 are connected is used. As shown in FIG. 7, such a pair of connectors 8 is fixed to the wire harness 10 with the tape 9 and is housed inside the protector 11 made of synthetic resin.

[0003]

[Problems to be solved by the device]

 However, there are the following problems in the conventional method for connecting the wires that make up the wire harness to each other. That is, 1) In the splice connection method shown in FIG. 4, the work of stripping the middle part of the wire, crimping the connection terminal, and winding the insulating tape is performed, and the workability is poor. 2) In the twisted wire connecting means shown in FIGS. 6 and 7, since a protector is used and the like, the connecting portion is enlarged, and the cost and weight are increased.

[0004]

Means and Actions for Solving the Problem The present invention provides a wire harness connecting part that solves the above-mentioned problems, in which a bus bar having a plurality of press-connecting parts is embedded in an insulator. The insulator is characterized by being provided with a through groove for press-fitting a desired electric wire forming a wire harness into the press-connecting connection portion and a groove for fixing the electric wire. As described above, the bus bar having the plurality of pressure contact connecting portions is embedded in the insulator, and the insulator is provided with the through groove for press-fitting the electric wire into the pressure contact connecting portion and the groove for fixing the electric wire. Then, by fixing the electric wires forming the wire harness to the respective pressure contact connection portions of the bus bar through the through grooves of the insulator, it is possible to connect a plurality of electric wires. In addition, the insulator surrounding the bus bar can fix the electric wire and insulate the bus bar. By using a pair of bus bars, it is possible to connect the electric wires forming the twisted wire.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is an assembly explanatory diagram of an embodiment of a wire harness connecting component according to the present invention. The T-shaped bus bar 21 is provided with three pressure contact connecting portions 22, and the bus bar 21 is embedded in the insulator 23. The insulator 23 is provided with a through groove 24 for press-fitting an electric wire (not shown) into the press-connecting connection portion 22 and three fixing grooves 25 for fixing the electric wire. By using two of the wire harness connecting parts 26, as shown in FIG. 2, one wire of each of the three twisted wires 27 is inserted into the pressure contact connecting portion 22 of one wire harness connecting part 26. By crimping, the three twisted wires can be electrically connected. Further, the structure of the wire harness connection component 29 may be embedded in a single insulator 28 so that the pair of bus bars 21 are not in contact with each other, as shown in FIG. Furthermore, the bus bar may be covered with an insulator so that both sides of the bus bar are sandwiched between the insulators to form a connecting component for a wire harness. Note that the number of press-connecting connection portions of the bus bar is not limited to three, and the shape of the insulator is not limited to the circular shape as in the above embodiment, but may be trapezoidal or triangular.

[0006]

[Effect of device]

 As described above, according to the present invention, a bus bar having a plurality of press-connecting connection parts is embedded in an insulator, and desired wires forming a wire harness are press-fitted into the press-connecting connection parts. Since there is a through groove and a groove for fixing the electric wire, there is no need to use a joint connector, so the number of circuits is reduced, the connection part is compact, weight is reduced, and cost is also reduced. It has an excellent effect.
