産業上の利用分野
本発明は分岐を有する配線、とくに多数の分岐
を有するワイヤリングハーネス等における電線の
分岐接続方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to wiring having branches, particularly to a method for branching and connecting electric wires in wiring harnesses having a large number of branches.
従来の技術
ワイヤリングハーネスなどで１本の主線に対し
複数の分岐線を設けるに当つては、従来は接続作
業の簡便さから、接続すべき電線双方の絶縁被覆
を除去したのち圧着端子金具などを用いて導電線
相互を圧着接続することが行なわれていた。Conventional technology When providing multiple branch lines to one main line in wiring harnesses, etc., conventionally, for ease of connection work, the insulation coating of both wires to be connected was removed, and then crimp terminal fittings, etc. were attached. Conductive wires were used to connect conductive wires by crimping.
しかし、圧着端子金具はその大きさや形状など
について制約があり、たとえば第７図の如く主電
線ａの末端に複数の分岐電線b1，b2……の末端を
まとめて圧着端子金具ｃを用いて圧着結合する

性がよくない欠点があつた。またこのような圧着
端子金具を用いた結合は簡便ではあつても、圧着
力にバラツキがあり、電線が抜け落ちたり、使用
中に酸化を受け接触抵抗が増大する、などの問題
があつた。 However, there are restrictions on the size and shape of crimp terminal fittings, and for example, as shown in Fig. 7, the ends of multiple branch electric wires b 1 , b 2 . Alternatively, as shown in Figure 8, remove the insulation coating from the necessary parts of the main wire a and connect the branch wires to each branch wire.
The ends of b 1 , b 2 ... are crimped and connected using crimp terminal fittings c 1 , c 2 ..., and only 2 to 3 branch wires can be attached at each location, so it is difficult to connect multiple branches. The disadvantage of installing electric wires was that it required more man-hours and was not easy to work with. Furthermore, although the connection using such crimp terminal fittings is simple, there are problems such as variations in crimp force, wires falling out, and contact resistance increasing due to oxidation during use.
解決しようとする問題点
本発明は、多数の分岐を有する電線束を作るに

分岐接続を行なう構成を採用した。Means for Solving the Problems In order to solve the above-mentioned problems, the electric wire branch connection method of the present invention removes the insulation coating at the terminals of a plurality of electric wires to expose the conductors, and connects these exposed conductors together. These exposed conductors are bundled together and subjected to pressure molding or heat fusion processing to form a single terminal in which these exposed conductors are integrated, and branch connections are made between multiple electric wires via this terminal.

ことができる。 In addition, in order to pressure-form the wire end into a terminal shape,
A method can be used in which the exposed conductors of the electric wires are arranged and housed in a molding frame and are welded together under pressure using, for example, an ultrasonic welder. For such pressure forming, various pressure welding means, forging means, etc. may be used, and in addition to the electric wires, metal powder or metal plates that promote fusion may be combined to fill the gaps between the electric wires or Molding may be performed so as to cover the surface, thereby increasing the capacity of the terminal portion.
更に、このようにして形成された端子部は、適
宜の保護カバーを被せて分岐部分を補強し、ある

けた形状を有する。Embodiment FIG. 1 shows an example of a branch connection structure for electric wires according to the present invention, in which one ends of electric wires A 1 , A 2 , A 3 . . . are brought together to form a ring-shaped terminal C. This terminal C has a shape in which a screw hole is provided in a flat disk-shaped electrical contact plate.

Next, the exposed conductor B is inserted into the terminal pressure molding anvil, and welding is completed while pressurizing it from above and below using an ultrasonic pressure welding machine or the like to mold it into one piece.

ない。 The terminal C formed in this way is integrated by pressure welding and the conductors do not separate, but the boundary between the terminal C and the wires A 1 , A 2 ... is strong during pressure welding. Since it is under stress, it may be susceptible to bending. Therefore, in order to protect the connection structure from external forces, it is recommended to cover the wires with synthetic resin covers D 1 and D 2 as shown in Figures 3 and 5, and bundle the wires together. . In this way, even if an external force is applied to the wire, the external force will not act in the direction of tearing, so there is no risk of an accident occurring.

用いることができる。 Such a branch connection structure (Fig. 4) with exposed terminal C is useful for constructing wire bundles, such as ground wiring that is screwed directly to the body of a car, or when branching multiple wires from one power terminal. In addition, the connection structure in which the terminal C is completely covered (Fig. 5) is suitable when, for example, many branch wires are taken out from one main wire, It can be used for signal circuits and power supply circuits.

性も向上する利点がある。Effects of the Invention According to the present invention, whereas the conventional crimp-type connection using terminal fittings had a limit of 2 to 3 branches, it is possible to perform connections with a much larger number of branches, about 10. Moreover, since the conductors of each wire are fused and integrated, contact resistance is extremely reduced and connection strength is high, achieving a highly reliable connection that does not deteriorate over time. In addition, the number of branch points is small, and many wires can be branched and connected at once, which not only increases the productivity of manufacturing wire bundles, but also
Since the branch connection portion is formed as a terminal, there is no need to use other terminal fittings, and there is an advantage that the workability of wiring installation is improved.
