Abstract

<P>PROBLEM TO BE SOLVED: To reduce man-hours for cabling and manufacturing processes by reducing the number of components for connecting auxiliary machines together. <P>SOLUTION: An auxiliary machine comprises an auxiliary machine body 11 comprising a resin mold member, an electric wire 12 whose one end is directly connected to the auxiliary machine body 11, and a connector 13 connected to the other end of the electric wire. The connector 13 houses a crimping terminal 15 which is crimped to a conductor 14 of the electric wire 12 inside a housing 20 comprising the resin mold member. The connector 13 is provided with a coalescence mechanism comprising a recessed part 16 and a protruding part 17 so that it is coalesced with other connector 13 to constitute a single connector. Thus, no component such as a crimping terminal or a connector for connecting the auxiliary machine 10 to the electric wire 12 is required, resulting in the reduced number of components. The man-hour for cabling is reduced since the auxiliary machine 10 is not required to be connected to the electric wire 12. <P>COPYRIGHT: (C)2004,JPO

2. Description of the Related Art At present, as shown in FIG. 7, a wire harness 100 is mainly used for connecting auxiliary machines 101 to which electric components such as an automobile are connected. The wire harness 100 is obtained by bundling a plurality of electric wires 102 connecting the respective auxiliary devices 101 in a harness shape and covering the electric wires 102 with a protective member 106 such as an insulating tape. Usually, one end of each electric wire 102 constituting the harness Has a crimp terminal 1
The crimp terminals 103 are mounted in a connector 105 connected to a connector 104 or the like provided in each accessory 101. The other end of each electric wire 102 is commonly connected to a connector 120 for connecting the wire harness 100 to another circuit or the like. Further, the connector 105 of the wire harness 100
Is formed in a different shape for each accessory 101, and is devised so as not to cause a connection error or the like.

FIG. 8 shows such a wire harness 100.
6 is a flowchart showing a manufacturing process of the first embodiment. First, the strands of the electric wires 102 constituting the wire harness 100 are twisted (S100), individually extruded to form an insulating coating (S101), and the extruded wires are assembled (S10).
2), the assembled wires are sorted (S103). The process up to this point is called an extrusion process.

[0004] Next, an auxiliary machine 10 for connecting the sorted wires.
1 is measured individually (S200), the measured wire is cut (S201), the insulating coating of the terminal is removed, and the wire is exposed (extruded) (S202). Crimp terminals 103 are individually crimped to each
3), the wires crimped to the crimp terminals 103 are assembled (S2
04), the assembled wires are sorted (S205). The process up to this point is called a pressure bonding process.

[0005] If necessary, the insulating coating at a predetermined position between the ends of the wire is removed to expose the strand (intermediate tapping) (S300), and a joint terminal for branching is crimped (S301). The wire rods to which the joint terminals are crimped are assembled (S302), and the collected wire rods are sorted (S302).
303). The process so far is called a joint process.

The respective terminals of the wire rod to which the respective terminals are attached in this manner are inserted into, for example, the connector 105 (S40
0), a subassembly (S / Assy) is formed by performing temporary assembly (S401), and the formed subassemblies are assembled (S402). The configuration up to this point is called a sub-assembly step.

After forming the sub-assembly as described above, a branch is formed (S500), and a terminal is inserted (S50).
1) A tape such as an insulating tape, which is the protection member 106, is wound around the wire (S502), and various kinds of exterior are attached to form a wire harness (W / H) 100 (S503), and the formed wire harness 100 is assembled. (S504). The steps so far are referred to as an assembly step.

The assembled wire harness 100
Is completed (S600), the product number and lot are pasted (S601), and finally the wire harness 100 is shipped (S602). This process is called an inspection shipping process. Thus, in order to manufacture the wire harness 100,
Broadly speaking, it is necessary to individually perform various processes such as an extrusion process, a crimping process, a joint process, a sub-assembly process, an assembly process, and an inspection shipping process.

For example, a large number of connectors are used for a branch portion and a joint portion, and when the number of connected auxiliary devices 101 increases, the number of components such as the connectors 104 and 105 also increases, so that the cost may increase. Also, wire harness 10
In arranging 0, it is necessary to attach a connector 105 having a different shape to each auxiliary machine 101 to be laid and to crimp the crimp terminal 103 to the electric wire 102, so that the number of steps in the arranging process is dramatically increased. Costs may increase. Further, since it is necessary to wind an insulating tape or the like as the protection member 106, the number of manufacturing steps may inevitably increase.
