  Next, a method for wiring the wire harness 23 to the joint connector 11A will be described.

  FIG. 3 is a diagram for explaining the wiring procedure of the wire harness to the joint connector.

(Main body support process)
First, as shown in FIG. 3A, the joint connector body 12 is supported by the support jig 41. The support jig 41 has a support plate 43 fixed to the upper end of a support column 42, and the joint connector body 12 is placed on the support plate 43 and supported. An electric wire holder 45 is provided on the side of the support jig 41. The electric wire holder 45 includes a support bar portion 46 supported so as to be rotatable about a vertical axis, and an electric wire dividing bar portion 47 extending laterally from the upper end of the support bar portion 46. ing. The electric wire dividing rod portion 47 has three electric wire holding concave portions 48 bent so as to be recessed downward.

(Wire holder placement process)
Next, as shown in FIG. 3 (b), a joint in which the electric wire dividing bar portion 47 of the electric wire holder 45 is supported by the support jig 41 by rotating the support bar portion 46 of the electric wire holder 45. The connector body 12 is disposed above the protector portion 21 and the receptacle portion 33. If it does in this way, each electric wire holding recessed part 48 of this electric wire division | segmentation rod part 47 will be arrange | positioned at the protector part 21 side in each receptacle part 33. FIG.

(Wire connection process)
Next, as shown in FIG. 3C, the electric wires 15 drawn from the corrugated tube 24 of the wire harness 23 are wired and bundled in the protector portion 21, and the electric wires formed on the electric wire dividing rod portion 47 of the electric wire holder 45. While being hung and held in the holding recess 48, the divided electric wires 15 are connected to the connector 27.

(Electric wire retainer retracting process)
As shown in FIG. 3D, when each wire 15 hung on the wire holding recess 48 is connected to the connector 27, the support rod portion 46 of the wire holder 45 is rotated as shown in FIG. As a result, the electric wire dividing rod portion 47 of the electric wire holder 45 is retracted from the upper position of the protector portion 21.

(Connector connection process)
Each connector 27 connected to the electric wire 15 is inserted and connected to the corresponding receptacle portion 33 from above.

(Wire binding process)
As shown in FIG. 3 (f), the end portion of the corrugated tube 24 of the trunk line 23 a of the wire harness 23 is disposed on the protector portion 21, and then the lid portion 13 is attached to the joint connector main body 12.

  And according to the wiring method to said joint connector, it connects with the protector part 21 holding the extraction | drawer part A of the electric wire 15 in the trunk line 23a of the wire harness 23, and the edge part of the electric wire 15 pulled out from the trunk line 23a. The wire harness 23 can be wired very easily to the joint connector 11A provided integrally with the receptacle 33 to which the connector 27 can be connected. That is, it is not necessary to protect the electric wires 15 drawn and branched from the main line 23a with the tape or the corrugated tube to form the branch lines, and the cost can be reduced by simplifying the wiring work.

  Moreover, since it is not necessary to fix the protector part 21 and the receptacle part 33 separately to a vehicle frame or the like, the workability can be greatly improved by simplifying the fixing work. In addition, since wiring can be performed simply by inserting the connector 27 into the receptacle portion 33, the number of jigs can be reduced as compared with the case where the connector is inserted into a separate connector main body, and attachment work is easy.

  Since such a joint connector 1 is connected to the end of the branch line 2 branched from the wire harness 5, an electric wire corresponding to the length of the branch line 2 with the wire harness 5 is required. Must be bundled and protected with a tape or a corrugated tube to form the branch line 2, which increases the cost.

  Further, since the joint connector 1 is separately provided at a position away from the protector 6 at the branching point of the wire harness 5, the protector 6 and the joint connector 1 are respectively connected to the vehicle frame at the time of wiring so as not to swing. It is necessary to fix to the etc. with a fixing part. For this reason, the complicated fixing operation | work of these protectors 6 and the joint connector 1 is required, and a cost increase will be caused.

  Further, since the joint connector 1 has a structure in which the connector 3 is connected to each of the plurality of branch lines 2 and these connectors 3 are connected to the connector body 4, when the branch lines 2 are connected to the respective connectors 3. In addition, a plurality of jigs for supporting each connector 3 is required, and an operation for attaching the connector main body 4 to the connector 3 is also required separately.
