  The present invention relates to a connector fixing method for fixing a connector to a wire harness, and more particularly to a connector fixing method capable of improving workability when fixing a connector connected to an electric wire branched from the wire harness to the connector. .

A plurality of electric wires are housed in a wire harness for an automobile. A branch circuit is formed by taking out part of the electric wire stored in the wire harness. Electric wires branched off from the wire harness are connected to various electronic devices mounted on the automobile.
When the electric wire branched out from the wire harness is connected to an electronic device mounted on an automobile, various connectors are often used.
When connecting the wire harness and the connector, in the case of standard specifications, a regular wiring may be used. However, when some specifications are changed, another connector may be fixed on the wire harness in order to form an optional circuit.

As shown in FIG. 11, such a conventional wire harness 100 has a bundle of wires made up of a plurality of wires 101, and a plurality of wires 101 that are a part of the plurality of wires 101 serve as branch lines 102 from the main line 103. It is branched (Patent Document 1). A connector set 104 is attached to the end of the branch line 102. The connector set 104 and the branch line 102 are covered with a transparent plastic bag 105 that is a covering material.
The connector set 104 and the branch line 102 are fixed to the trunk line 103 with an adhesive tape 106 while being covered with a plastic bag 105.

  The connector set 104 is called a joint connector, and a female connector 201 into which a terminal (not shown) attached to each of the ends of the plurality of electric wires 101 constituting the branch line 103 is inserted, and the female connector The male connector 202 is fitted to the connector 201. The male connector 202 is provided with a bus bar (not shown).

  When the male connector 202 and the female connector 201 are fitted, a bus bar (not shown) provided on the male connector 202 is fitted with a plurality of terminals (not shown) inserted into the female connector 201. It is supposed to be. By the plurality of terminals, a plurality of terminals (not shown) attached to the end of the branch line 103 are short-circuited. Accordingly, the shape of the bus bar (not shown) determines which terminal and which terminal are short-circuited among a plurality of terminals (not shown).

In the conventional wire harness 100, the mouth of the plastic bag 105 is tied by an adhesive tape 106, and the branch root portion of the branch line 102 is fixed to the trunk line 103 by the adhesive tape 106. The adhesive tape 106 has the branch line 102 and the trunk line 103 wound together from above the plastic bag 105 from the branch root portion of the branch line 102 toward the connector set 104.
In this manner, the wire harness 100 is formed by winding the adhesive tape 105 together around the connector set 104 and the trunk line 103 from above the plastic bag 105.
