Each of them is integrally projected. The engaging portion 16 and the locking claw 21 constitute a locking means for locking the closed state between the side walls 13 and 13 of the protector body 11 and the cover 20.

尚、図３中符号３０はワイヤハーネス８を組み付ける板状の治具であり、この治具３０上にはプロテクタ本体１１を保持する枠状の本体保持具３１とワイヤハーネス８の分岐線８ｂを保持する棒状の分岐線保持具３２等を取り付けてある。また、ワイヤハーネス８の分岐線８ｂの先端にはコネクタ９を接続してある。 3 is a plate-shaped jig for assembling the wire harness 8. On the jig 30, a frame-shaped body holder 31 for holding the protector body 11 and a branch line 8b of the wire harness 8 are provided. The holding | maintenance bar-shaped branch line holder 32 etc. which hold | maintain are attached. A connector 9 is connected to the tip of the branch line 8 b of the wire harness 8.

以上実施形態のワイヤハーネス用プロテクタ１０によれば、図３（ａ）に示すように、治具３０上でワイヤハーネス８を組み付ける際に、分岐線保持具３２で保持されて水平方向に延びる分岐線８ｂの根元部分をプロテクタ本体１１の側壁１３のＵ字状の切欠き部に連通したＬ字状で分岐線保持用の延長片１５の基端部１５ａに結束バンドＢを介して仮固定する。 According to the wire harness protector 10 of the above embodiment, as shown in FIG. 3A, when the wire harness 8 is assembled on the jig 30, the branch is held by the branch line holder 32 and extends in the horizontal direction. The base portion of the wire 8b is temporarily fixed to the proximal end portion 15a of the branch line holding extension piece 15 via the binding band B in an L shape communicating with the U-shaped cutout portion of the side wall 13 of the protector body 11. .

次に、ワイヤハーネス８の図示しない他の分岐線の端末処理を行った後で、プロテクタ本体１１の両側壁１３，１３の各上端１３ａにカバー２０を組み付け、その開口部１１ｂを覆う。そして、図３（ｂ）に示すように、ワイヤハーネス８を治具３０から取り外し、プロテクタ本体１１からＬ字状で分岐線保持用の延長片１５に沿って下方（三次元方向）に分岐経路をとる分岐線８ｂに対し、延長片１５の先端部１５ｃと分岐線８ｂとを粘着テープＴを介して本固定する。 Next, after terminal processing of another branch line (not shown) of the wire harness 8 is performed, the cover 20 is assembled to the upper ends 13a of the side walls 13 and 13 of the protector body 11, and the opening 11b is covered. Then, as shown in FIG. 3B, the wire harness 8 is removed from the jig 30, and is branched downward (three-dimensional direction) along the branch line holding extension piece 15 in an L shape from the protector body 11. The tip 15c of the extension piece 15 and the branch line 8b are permanently fixed via the adhesive tape T to the branch line 8b.

このように、プロテクタ本体１１の下方の三次元方向に分岐経路をとるワイヤハーネス８の分岐線８ｂを、治具３０上でプロテクタ本体１１の延長片１５の基端部１５ａにて結束バンドＢで仮固定し、治具３０から外した後で、延長片１５の先端部１５ｂにて粘着テープＴで本固定する固定方法を併用することによって、分岐線８ｂの分岐線長Ｌの公差内で分岐線８ｂを分岐線保持用の延長片１５に簡単かつ確実に固定して、下方の三次元方向に分岐線８ｂを備えたワイヤハーネス８を簡単に作製することができる。 In this way, the branch line 8b of the wire harness 8 that takes a branch path in the three-dimensional direction below the protector main body 11 is connected to the binding band B at the base end portion 15a of the extension piece 15 of the protector main body 11 on the jig 30. Branching within the tolerance of the branch line length L of the branch line 8b by using the fixing method of temporarily fixing and fixing with the adhesive tape T at the tip 15b of the extension piece 15 after being removed from the jig 30 The wire harness 8 having the branch line 8b in the lower three-dimensional direction can be easily manufactured by fixing the line 8b to the extension piece 15 for holding the branch line easily and reliably.

尚、前記実施形態によれば、延長片の基端部と分岐線とを結束バンドで固定すると共に、該延長片の先端部と該分岐線とを粘着テープで固定するようにしたが、延長片の基端部と分岐線とを粘着テープで固定すると共に、該延長片の先端部と該分岐線とを結束バンドで固定するようにしても良い。また、固定手段は結束バンドと粘着テープに限られるものではないことは勿論である。 According to the embodiment, the base end portion of the extension piece and the branch line are fixed with the binding band, and the tip end portion of the extension piece and the branch line are fixed with the adhesive tape. While fixing the base end part and branch line of a piece with an adhesive tape, you may make it fix the front-end | tip part of this extension piece and this branch line with a binding band. Of course, the fixing means is not limited to the binding band and the adhesive tape.
