  A “wire wiring method” according to an embodiment of the present invention, a “wiring module” assembled by the wire wiring method, and an “electric connection box” having the wiring module will be described with reference to FIGS. .

  The “wire routing method” of the present embodiment is a method of assembling the two types of wiring modules 1A and 1B shown in FIGS. 3 and 4 by routing the wires 2 on the wiring sheet 3 shown in FIGS. . The wiring modules 1A and 1B are wiring modules in which the electric wires 2 are routed on the same wiring sheet 3 with different circuit patterns.

  The wiring sheet 3 is made of synthetic resin, and includes an electric wire routing portion 4 provided in the center and a plurality of electric wire receiving grooves 5 provided in parallel at positions surrounding the electric wire routing portion 4. It has one. In the electric wire routing portion 4, a plurality of pin through holes 41 are formed in a plate portion 40 that positions the plurality of electric wires 2 on the surface. The pin passage hole 41 is a hole through which a pin 61 of the routing jig 6 described later is passed. The electric wire receiving groove 5 is a groove for receiving the electric wires 2 and fixing the electric wires 2. A through hole 51 through which the press contact blade 7 (shown in FIG. 6) passes is formed in the bottom wall of the electric wire receiving groove 5. The electric wire 2 is a covered electric wire in which a core wire is covered with an insulating coating, and is connected to the press contact blade 7 by being inserted into a slot of the press contact blade 7 through the through hole 51.

  As shown in FIG. 5, the routing jig 6 has a plate-like base portion 60 on which the wiring sheet 3 can be stacked, and a plurality of pins 61 erected from the base portion 60. Yes. In the present embodiment, the plurality of pins 61 are made of metal. Further, the plurality of pins 61 are passed through only a part of the plurality of pin through holes 41 of the wiring sheet 3. Further, the routing jig 6 shown in FIG. 5 has the wiring sheet 3 shown in the figure (only in FIG. 5, in order to explain the use of the plurality of pin passage holes 41, reference numerals 41 a and 41 b are provided on the pin passage holes.
