2. Description of the Related Art Generally, a wire harness mounted on a vehicle body or an electric device is connected to a battery or a plurality of electric circuits. Therefore, a wire harness branch line is branched from a wire harness main line and is provided on this branch line. By connecting the connector provided on the other wire harness branch line to the connector, the battery and a plurality of electric circuits are connected to each other. It is designed to be fixed to the main line.

As a conventional fixing structure of this type of connector to a wire harness, for example, the structures shown in FIGS. 3 to 6 are known. In FIG. 3, reference numeral 1 denotes a wire harness trunk line, and a wire harness branch line 2 branches from a predetermined portion of the wire harness trunk line 1, and a tip end of the branch line 2 is a tip end of another wire harness branch line (not shown). A connector 3 is provided which is fitted to the connector provided in the section. Then, when another connector is fitted to the connector 3, the tape 4 is used to connect the connector 3
Both connectors are fixed to the wire harness main line 1 by fixing them to the wire harness main line 1.

In the structure shown in FIG. 4, the connector 3 is fitted with the connector 6 provided at the tip of the other wire harness branch wire 5, and then the wire harness branch wire 5 is fixed by the fixing band 7. It is fixed to the harness trunk line 1. In addition, as shown in FIG. 5, the connector 3, 6 is covered and supported by the U-shaped receiving portion 9 fixed to the wire harness trunk line 1 by the fixing band 8 so that the connector 3, 6 is connected to the wire. It is fixed to the harness trunk line 1.

Further, in the structure shown in FIG. 6, the connectors 3 and 6 are provided with U-shaped hooks 10 and 11, and are fixed to the wire harness main line 1 by a tape 12 and are L-shaped on the upper surface. A clip 13 having hooks 13a and 13b is provided. First, after fixing the clip 13 to the wire harness main line 1 by the tape 12, both connectors 3 and 6 are fitted, and then the hooks 13a and 13b are attached. By engaging the hooks 10 and 11, both connectors 3 and 6 are fixed to the wire harness main line 1 via the clip 13 (for such a conventional example, see, for example, Japanese Utility Model Laid-Open No. 2-61081). ).

[0006]

However, in the one shown in FIG. 3, since the connector 3 is fixed to the wire harness main line 1 by the tape 4, fixing work of the connector 3 is troublesome and There is a problem that the number of man-hours for managing the parts is increased by the amount required for the separate tape 4.

Further, in the structure shown in FIG. 4, since the wire harness branch line 5 is fixed to the wire harness trunk line 1 by the fixing band 7, the fixing of the connectors 3 and 6 is unstable and a separate body. There is a problem that the man-hours for managing the parts are increased by the amount required for the fixing band 7. Further, in the case shown in FIG. 5, the fixing band 8
Since the connectors 3 and 6 are fixed to the wire harness main line 1 by the U-shaped receiving portion 9 having the
However, there has been a problem that the man-hours for managing the parts are increased by the necessary amount and the cost is increased by the necessary amount for the receiving portion 9.

Further, in the structure shown in FIG. 6, it is necessary to fix the clip 13 to the wire harness trunk line 1 with the tape 12 and to engage the hooks 13a and 13b with the hooks 10 and 11, so that the connector A lot of work man-hours are required for fixing 3 and 6, and the workability is poor.
There is a problem that the cost increases as much as the separate clip 13 is required.

Therefore, in the invention according to claims 1 and 2, the number of parts required for fixing the connector is reduced so that the connector can be easily fixed to the wire harness trunk line, and the workability of fixing the connector is improved. It is an object of the present invention to provide a structure for fixing a connector to a wire harness that can be improved and can reduce the man-hours for managing parts and the cost.
