【０００８】[0008]
以下、実施例に基づいて詳しく説明する。まず、本考案の一実施例を示す図１ を参照して、本考案のワイヤハーネス用プロテクタは、丸めて接合すると筒体を なす筒部１の端縁５・６に接合係止部２が設けてあり、この接合係止部２の接合 係止によって段階的可変内径の筒体をなす樹脂製の筒部１がプロテクタ主部をな している。 Hereinafter, a detailed description will be given based on examples. First, referring to FIG. 1 showing an embodiment of the present invention, in a protector for a wire harness of the present invention, a joint locking portion 2 is formed on an end edge 5 or 6 of a tubular portion 1 which forms a tubular body when rolled and joined. By the joining and locking of the joining and locking portion 2, the resin-made tubular portion 1 forming a tubular body having a gradually variable inner diameter serves as a main part of the protector.
【０００９】 即ち、その接合係止部２は、筒部１の一側の端縁５に、筒体の軸心９と平行す る膨出頭４を有する膨出頭条３を一体に形成して他側の端縁６に臨ませると共に 、その端縁６には、膨出頭条３の膨出頭４を着脱自在に受け入れる中間膨大部７ を有す係止凹溝８が、相手側の膨出頭条３に対向して設けられ、この膨出頭条３ と係止凹溝８が係止凸部と係止凹部となって接合係止部２を構成している。That is, the joint locking portion 2 is formed by integrally forming the bulging head strip 3 having the bulging head 4 parallel to the axis 9 of the tubular body on the end edge 5 on one side of the tubular portion 1. A locking recessed groove 8 having an intermediate enlarged portion 7 that detachably receives the bulging head 4 of the bulging head strip 3 is provided on the end edge 6 of the bulging head on the other side. The bulging head strip 3 and the locking concave groove 8 are provided so as to face the strip 3, and form the joint locking portion 2 as a locking projection and a locking recess.
【００１０】 そして、この係止凹溝８は軸心９と平行して隣接並列した複数溝（図示は三溝 ）になっており、その係止凹溝８群の任意の一溝を選んで膨出頭条３を「パチン 」と嵌め込んで筒部１の両端縁５・６を接合係止すると、図示点線のように、筒 部１が所要内径Ｄの円筒体をなす構造になっている。さらに、この筒部１の中間 部分に、軸心９と平行して帯状をなし、軟質樹脂によって形成された可撓部１１ が設けられ、その可撓部１１の両側は、電線束１３を保護するに足る強度を有す る剛性度の高い硬質樹脂で成形された円弧周壁部１０に形成されており、可撓部 １１を曲げ中心として筒部１を丸めて接合係止部２を接合すると、円弧周壁部１ ０が電線束１３の外周に概ね接して「がたつき」なく電線束１３を収容し、筒部 １をプロテクタ主要部となすワイヤハーネス用プロテクタが、ワイヤハーネス１ ２の所定位置にワンタッチ的に装着セットされるようになっている。The locking recessed groove 8 is a plurality of grooves (three grooves shown in the figure) that are adjacently arranged in parallel with each other in parallel with the axis 9, and any one of the locking recessed grooves 8 group is selected and expanded. When the protruding line 3 is fitted with a "sling" and both end edges 5 and 6 of the tubular portion 1 are joined and locked, the tubular portion 1 has a structure having a required inner diameter D as shown by a dotted line in the figure. Further, a flexible portion 11 formed in the shape of a strip and made of a soft resin in parallel with the shaft center 9 is provided at an intermediate portion of the cylindrical portion 1, and both sides of the flexible portion 11 protect the wire bundle 13.

A wire harness protector, in which the arcuate circumferential wall portion 10 substantially contacts the outer circumference of the wire bundle 13 and accommodates the wire bundle 13 without “rattle”, and the tubular portion 1 is a main part of the protector, is a predetermined wire harness 12. It is designed to be attached and set in one-touch position.
【００１１】 次に、図２図３を参照して本考案の他の実施例のワイヤハーネス用プロテクタ を説明する。まず、図２のものは図１実施例と同一の膨出頭条３と係止凹溝８か らなる筒部１の接合係止部２において、係止凹溝８が筒部１の外周側に形成され ていると共に、可撓部１１が可撓部１１の両側の円弧周壁１０と同一樹脂材にし て、円弧周壁１０より薄く形成された可撓帯になっている。一方、図３のものは 、膨出頭条３と係止凹溝８からなる接合係止部２において、それ等を端縁５・６ の全長に形成しないで、端縁５・６の両端と中央に分割形成したセパレートタイ プになっている。Next, a wire harness protector according to another embodiment of the present invention will be described with reference to FIGS. First, in FIG. 2, in the joint locking portion 2 of the tubular portion 1 including the same bulging head strip 3 and the locking concave groove 8 as in the embodiment of FIG. 1, the locking concave groove 8 is on the outer peripheral side of the tubular portion 1. In addition, the flexible portion 11 is made of the same resin material as the circular arc peripheral walls 10 on both sides of the flexible portion 11 to form a flexible band thinner than the circular arc peripheral wall 10. On the other hand, in the one shown in FIG. 3, in the joint locking portion 2 composed of the bulging head strip 3 and the locking recessed groove 8, they are not formed on the entire length of the edges 5 and 6, but at both ends of the edges 5 and 6. It is a separate type that is divided and formed in the center.
【００１２】 以上の各実施例は前記の作用があり、複数の係止凹溝８を択一して膨出頭条３ を「パチン」とかみ合せると、筒部１の内径が段階的に可変となるので、電線束 １３の径がある範囲で変動しても、プロテクタとしての必要な内径条件を満足さ せて良好なプロテクタ機能を奏し、多サイズの電線束１３に有効に共用できる。 そして、そのプロテクタの筒状姿勢を固定するためのテープ巻き作業が省略でき る。Each of the above-mentioned embodiments has the above-mentioned action, and when the plurality of locking concave grooves 8 are selected and the bulging head strip 3 is engaged with the "pachin", the inner diameter of the tubular portion 1 is changed stepwise. Therefore, even if the diameter of the wire bundle 13 fluctuates within a certain range, the protector satisfies the necessary inner diameter condition, exhibits a good protector function, and can be effectively shared by multiple size wire bundles 13. Then, the tape winding work for fixing the tubular posture of the protector can be omitted.
【００１３】[0013]
