Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wire harness locking structure for locking a plurality of wire harnesses to an attached object such as a fuse box or a protector.

[0002]

[Prior Art]

 5A and 5B show a fuse box 1 using a conventional wire harness locking structure. In the figure, the fuse box 1 is composed of a fuse box body 3, a mounting portion 5 for fixing to the vehicle body, and an arm-shaped clamp 9 protruding from a side wall 7 of the fuse box body 3.

The arm-shaped clamp 9 is formed in an L shape integrally with the side wall 7 of the fuse box 1, and has a hook portion 9a at the tip thereof. Between the arm-shaped clamp 9 and the side wall 7 of the fuse box body 3, there is formed a locking portion 13 for locking a plurality of wire harnesses (hereinafter simply referred to as "wire harness") 11 bundled with tape or the like. ing. The distance between the arm-shaped clamp 9 and the side wall 7, that is, the size of the locking portion 13 is set by the diameter of the wire harness 11 to be locked in the locking portion 13.

In order to lock the wire harness 11 by the locking structure of the wire harness 11, the wire harness 11 is inserted into the locking portion 13 as shown in FIGS. 5B and 6A. Lock.

[0005]

[Problems to be solved by the device]

 However, in recent years, many automobiles have been classified, and even within the same vehicle model, the wire harness 11 has several diameters, from thin to thick, depending on the number of electrical components mounted on the vehicle. Since the size of the locking portion 13 of the arm-shaped clamp 9 is formed to match the diameter of the wire harness 11 having a large diameter, when the wire harness 17 having a small diameter is locked in the locking portion 13, As shown in (b), there is a possibility that the arm-shaped clamp 9 may come off from the opening, and there is a problem that the wire harness 17 having a small diameter cannot be securely fixed.

Therefore, an object of the present invention is to provide a wire harness locking structure capable of reliably fixing the wire harness regardless of the diameter.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a clamp arm that supports a wire harness between the clamp arm and a clamp arm that supports the clamp arm to and away from the side wall of the mount body. It is characterized in that it is constituted by positioning means for positioning at two or more predetermined positions with respect to the mounted body.

[0008]

[Action]

 According to the present invention, when a thick wire harness is locked between the clamp arm and the side wall, the clamp arm is positioned by the positioning means at a position apart from the side wall. As a result, a thick wire harness can be securely fixed between the clamp arm and the side wall.

Further, when the wire harness having a small diameter is locked between the clamp arm and the side wall, the clamp arm is positioned by the positioning means at a position close to the side wall. As a result, the distance between the clamp arm and the side wall becomes narrow, so that the wire harness having a small diameter can be securely fixed.

[0010]

【Example】

 Next, an embodiment of a fuse box 21 to which the wire harness locking structure according to the present invention is applied will be described with reference to FIGS.

FIG. 1 shows a fuse box 21 to which a wire harness locking structure is applied. In the drawing, the wire harness locking structure of the present embodiment includes a clamp arm 25 for supporting the wire harness 11 with the main body 3 of the fuse box 21 and the clamp arm 25 on the side wall of the fuse box main body 3. It is composed of a positioning means 45 which supports the clamp arm 25 so that it can be brought into contact with and separated from the fuse box 23 and positions the clamp arm 25 at two or more predetermined positions with respect to the fuse box body 3.

The clamp arm 25 is L-shaped, and projections 33 and 35 are provided on both sides of one piece so as to project from both sides. Further, a slit 43 is formed at the tip portion, and a stopper 41 is formed by being bent outward. A hook 25a is formed at the other end. A locking portion 27 is formed between the clamp arm 25 and the side wall 23. Further, one piece of the clamp arm 25 is inserted into a through hole 39 formed in a lower portion of a wall 31 in an opening 29 formed in the side wall 23.

The positioning means 45 is composed of projections 33 and 35, a through hole 39, and a stopper 41. As shown in FIG. 1, the clamp arm 25 has a first position where the opening edge of the wall 31 and the opening edge of the opening 29 are located between the stopper 41 and the protrusion 35, and as shown in FIG. At a second position where the opening edge of the wall 31 and the opening edge of the opening 29 are located between the protrusion 33 and the protrusion 33, and the opening of the wall 31 between the protrusion 33 and the other piece as shown in FIG. The edge and the opening edge of the opening 29 are positioned at the third position.

Next, in order to assemble the clamp arm 25 to the fuse box body 3, the tip end on the slit 43 side is made substantially linear and is inserted into the body 3 through the through hole 39. Then, after the tip end on the slit 43 side is inserted into the fuse box body 3, the tip end on the slit 43 side is bent to form the stopper 41. As a result, the clamp arm 25 can be assembled to the fuse box body 3 in a state in which the clamp arm 25 is prevented from coming off from the through hole 39.

Next, a case where the large-diameter wire harness 1 is locked and a case where the small-diameter wire harness 17 is locked to the fuse box 21 to which the wire harness locking structure is applied will be described.

As shown in FIG. 4A, when the large-diameter wire harness 11 is locked to the fuse box 21, the clamp arm 25 is pulled out from the fuse box main body 3 to the farthest position, and the protrusion 35 and The wall 31 and the opening edge of the opening 29 are positioned between the stopper 41 and the stopper 41. That is, the clamp arm 25 is positioned at the third position. Then, the wire harness 11 bundled with tape or the like is locked in the clamp arm 25.

Next, in order to lock the small-diameter wire harness 17 between the clamp arm 9 and the side wall 23, the clamp arm 9 is pushed toward the side wall 23 to a position closest to the side wall 23, The wall 31 and the opening edge of the opening 29 ride over the projection 35, and the clamp arm 9 is moved and positioned at the second position. Then, as shown in FIG. 4B, the small-diameter wire harness 17 is inserted and locked between the clamp arm 9 and the side wall 23. As a result, the wire harness 17 is securely fixed to the fuse box 21.

When the wire harnesses 11 and 17 are not locked, for example, when the fuse box 21 is moved as a component, the clamp arm 25 is inserted into the fuse box body 3 and the first position is set. To position. In this state, the clamp arm 25 does not project from the side wall 23 but is flush with the side wall 23.

As described above, according to this embodiment, the wire harnesses 11 and 17 can be reliably fixed to the fuse box 21 regardless of the diameters of the wire harnesses 11 and 17.

Further, as shown in FIG. 3, since the side wall 23 of the fuse box 21 and the clamp arm 9 are flush with each other, the clamp arm 9 is not damaged when the fuse box 21 is transported.

[Effect of the device]

 As described above, the wire harness locking structure according to the present invention has an excellent effect that the wire harness can be securely fixed to the mounted body regardless of the diameter.
