Description

  The present invention relates to a connector connection structure for a wire harness routed in an automobile or the like and a connection method thereof.

  As a conventional wire harness for automobiles, there is known a wire harness configured by combining a plurality of function-specific sub-harnesses that are sub-divided for each function classified according to the current value of the energization current (for example, Patent Document 1). reference).

  FIG. 2A is a system diagram illustrating an example of the wire harness configured as described above, and FIG. 2B is a top view illustrating a state in which the wire harness is routed in an actual vehicle. In this case, three function-specific sub-harnesses A, B, and C are prepared according to the current value of the energization current, and each sub-harness A, B, and C is connected to the control unit 50 at the root end. (Hereinafter, one end of the sub-harness connected to the control unit 50 may be referred to as a root end), and the branch end has a control unit. 50 includes connectors A2, B2, and C2 connected to connection destination connectors provided in a controlled device (a controlled device corresponds to an engine in FIG. 2) to be controlled by 50 (hereinafter, referred to as “controlled device”). Of the end portions of the sub-harness, a plurality of other end portions on the side connected to the controlled device may be referred to as branch ends).

As described above, the wire harness constituted by the plurality of sub-harnesses A, B, and C is generally manually arranged on a holding tool (what is called a protector or a branching member) that holds the wire harness. . At this time, one subharness is often assigned to each worker so that a plurality of workers route different subharnesses A, B, and C. And as shown in FIG.2 (b), it arrange | positions with respect to a real vehicle using the holders 20, 21, 22, and 23. FIG. In FIG. 2B, 10 is an engine room, 11 is a headlamp, 12 is a radiator, 15 is a passenger compartment, and 16 is a handle.
