Next, a wire cabling jig according to the invention for mounting electric wires in the second connector 60 with electric wires fitted into the first connector 43 described in Fig. 6 and an electric wire mounting method using the jig will be described.
In Fig. 1A, the second connector 60 includes a holder 61 and a cover 62 joined to the end of this holder 61 by a hinge. The holder 61 is provided with plural grooves 63 on which electric wires W are laid. A wire cabling jig 70 according to the invention is provided with a pedestal 71 for second connector on which the holder 61 and the cover 62 are respectively placed in the vicinity of one edge on a centerline of the wire cabling jig 70. Numeral 71A of the pedestal 71 for second connector is a holder pedestal 61, and numeral 71B is a cover pedestal 62. Then, a holder positioning protrusion 71T upward projecting from the holder pedestal 71A is provided.
Further, two kinds of positioning pins 72 (pin 72A and pin 72B) are erected on the wire cabling jig 70. One kind of pins is two connector positioning pins 72A for positioning a third connector 80, and is provided on the other edge of the wire cabling jig 70. The other kind of pins is plural (four in Figs. 1A to 1C) wire positioning pins 72B for positioning the electric wires, and is provided on the vicinities of four corners of the wire cabling jig 70.
Plural (three in Figs. 1A to 1C) electric wires W respectively extend in a horizontal direction from the top and bottom of the third connector fixed by the connector positioning pins 72A for the third connector 80, and each of the electric wires W is vertically gathered and is twisted around each of the wire positioning pins 72B as it is and is turned 90 degrees around and is routed at the four corners of the wire cabling jig 70 and the distal end of each of the electric wires W is strongly pulled in a direction opposite to the third connector 80 and thereby, the slack of the electric wires can be reduced.
A method for using the wire cabling jig according to the invention will be described in detail using Figs. 1A to 1C and 2A to 2C.
(1) In the first step of an assembly method, the holder 61 of the second connector 60 is brought just above the holder positioning protrusion 71T (see Fig. 1A) .
(2) The holder 61 is lowered below a void arrow of Fig. 1A and is inserted into the holder positioning protrusion 71T, and the second connector 60 is temporarily fixed on the pedestal 71 for second connector (see Fig. IB) .
(3) The third connector 80 with plural electric wires W is brought just above a pair of connector positioning pins 72A for the third connector 80, and the three vertical electric wires extend in a direction of straight traversing on the wire cabling jig 70 (Fig. 1C) .
(4) The whole third connector 80 with electric wires is lowered below a void arrow of Fig. 1C, and the third connector 80 is abutted on the outsides (the side opposite to the wire cabling jig 70) of the connector positioning pins 72A for the third connector 80, and the portion of the electric wires W of the root of the third connector 80 is pinched between the positioning pins 72A for third connector (Fig. 2A) .
(5) Thereafter, the portion of the three vertical electric wires W extending from the third connector 80 is sequentially moved along side surfaces of the four wire positioning pins 72B, 72B, 72B, 72B and is turned around. In that case, the electric wires W are loosely laid on the plural grooves 63 of the holder 61 temporarily fixed on the holder pedestal 71A on the way (Fig. 2A) .
(6) When the end of the portion of the three vertical electric wires W extending from the third connector 80 is strongly pulled in an arrow direction F of Fig. 2B (direction opposite to the third connector 80), the slack of the electric wires W is reduced by the wire positioning pins 72B and also the electric wires W loosely laid on the plural grooves 63 of the holder
61 are tightly fixed in each of the grooves 63 (Fig. 2B) . (7) In this state, the cover 62 is folded back at a hinge part and the holder 61 is covered with the cover 62 and thereby, the electric wires are pinched by the holder 61 and the cover
62 and the electric wires W are fixed inside the second connector 60. By this step, mounting of the electric wires in the second connector 60 is completed (see Fig.' 2C) . Thus, the wire cabling jig 70 is provided with the holder pedestal 71A, the cover pedestal 71B, the connector positioning pins 72A and the wire positioning pins 72B, and the electric wires W are held in the grooves 63 of the inside of the holder 61 in a state of no slack using the connector positioning pins 72A for the third connector 80, the wire positioning pins 72B and the holder pedestal 71A, and the holder 61 is covered with the cover 62 present on the cover pedestal 71B to fit the cover 62 into the holder 61, so that there is no room for occurrence of slack of the electric wires and therefore, a position of attachment of the holder and the cover to the electric wires can be determined accurately.
When the second connector 60 (Fig. 3A) to which the electric wires W described above are fixed is inserted into the first connector 43 of the housing 40 of the interior illuminating apparatus 10 for vehicle in which each component is mounted, the second connector 60 is fitted into the first connector 43 (Fig. 3B) and also the crimp blades 51 (Fig. 5) bite into the coat resin layer of the electric wires W to crimp the electric wires W (Fig. 6C) , so that a state in which the electric wires W are electrically connected to the bus bar 50 is obtained (see Figs. 3A and 3B) . By the above procedure, a method for assembling the interior illuminating apparatus 10 for vehicle is completed.
Thus, even when there is no metal component for conduction inside the holder 61 of the second connector 60, the crimp blades 51 directly bite into the coat resin layer of the electric wires W to crimp core wires of the electric wires , so that a metal component for conduction, for example, a conventional female terminal can be omitted.
Figs. 4A to 4C show a second embodiment of a wire cabling jig 70.
The second embodiment is characterized in that the vicinities of both sides of a pedestal 71 for second connector of the wire cabling jig 70 are provided with a pair of electric wire presses 73 for regulating movement of electric wires W.
The electric wire press 73 includes a vertical part 73A, an extension part 73B extending slightly downward in a horizontal direction from the top of the vertical part 73A, and a guide part 73C extending upward from the top of the extension part 73B. It becomes easy to guide the electric wires to the lower side of the extension part 73B of this electric wire press 73 by the guide part 73C extending upward, and the electric wires are lifted up from the extension part 73B toward a side surface of the pedestal 71 for second connector and thereby, the electric wires W vertically aligned previously can be horizontally aligned by the electric wire press 73, so that it becomes easy to insert the electric wires W into grooves 63 horizontally arranged in a holder 61.
The electric wire presses 73 support the electric wires W and regulate movement, positional deviation and slack of the electric wires W, and when one end of the electric wires W is pulled using a third connector 80 as a fixed end, it becomes easy to surely insert the electric wires W into the grooves 63 and it becomes easy to cable the electric wires W to the wire cabling jig 70 and also, mounting workability of a second connector 60 improves.
