Description

  The present invention relates to a protector for a wire harness and a method of attaching the protector to a wire harness, and more particularly, a protector that is externally mounted on a wire harness that is bent and routed in a two-wheeled vehicle or an automobile, and the shape of the protector is improved. This improves the mounting workability of the wire harness.

In recent years, wire harnesses routed in motorcycles and automobiles need to be routed accurately and densely in narrow spaces along the body frame and body panel, and the wire harness is protected from contact with external interference materials. Since it is necessary, there are many cases where a protector made of a resin molded product is provided and sheathed on the wire harness.
In addition, when the wiring harness is bent and wired in relation to the wiring location, it is necessary to bend the protector that houses the wire harness. In particular, in motorcycles such as motorcycles, there are many places where the wire harness is bent with respect to the body frame and the entire vehicle body is small, and interference of other parts with the wire harness is likely to occur. For this reason, there are many places where it is necessary to protect the wire harness which is bent or inclined and wired with a protector.

For example, a wire harness protector disclosed in Japanese Patent Laid-Open No. 2002-44825 (Patent Document 1) is provided as a device for bending a protector.
As shown in FIG. 8, the wire harness protector is divided into a first protector body 1 and a second protector body 2 where the protector body is bent, and the first protector set on a jig. A plurality of electric wires w are arranged in parallel in the main body 1, and the second positioning inner member 3 arranged at a distance from the first protector main body 1 is attached to the electric wires w in the parallel state, and the first protector main body 1 is covered with a first lid 4 and locked.
Next, the second positioning inner member 3 is twisted integrally by twisting the second positioning inner member 3, and the second positioning inner member 3 that fixes the parallel wiring w is attached to the second protector main body 2. 2 Wire the wire w to the protector body 2. Thereafter, the second protector main body 2 is covered with the second lid 5 and locked and, at the same time, the first protector main body 1 and the second protector main body 2 are connected.

JP 2002-44825 A

However, in the protector of the said patent document 1, in the state which performed the wiring operation | work of the electric wire w of the 1st protector main body 1 and the 2nd protector main body 2 separately, and twisted the electric wire w routed to the 1st protector main body 1. Since the second protector body 2 must be routed, the work procedure becomes complicated.
Moreover, after wiring the electric wire w to the 1st protector main body 1 and the 2nd protector main body 2, the 1st protector main body 1 and the 2nd protector main body 2 which covered the 1st cover body 4 and the 2nd cover body 5 are attached. In order to connect, it is difficult to adjust the wiring length of the electric wire w, and when the length of the electric wire w becomes long, it is from between the 1st protector main body 1 and the 2nd protector main body 2 at the time of a connection operation. There is a possibility that the electric wire will pop out, and the assemblability tends to deteriorate.

  The present invention has been made in view of the above problems, and after the wiring of the electric wire to the protector, the protector having a simple configuration that can bend the protector at a required position and reliably hold the bent state, It is an object to provide a method for attaching the protector to a wire harness.

In order to solve the above problems, the present invention is a protector for a resin molded product comprising a bottom plate portion extending in the insertion direction of a wire harness and a protector body having side plate portions on both sides of the bottom plate portion,
At the middle position in the insertion direction, it has a thin hinge portion that crosses the bottom plate portion, and the side plate portions on both sides of the thin hinge portion are provided with divided bent portions,
A locking piece provided with a locking claw at the tip protrudes from the outer surface of the bottom plate portion of the first side portion on one side sandwiching the bent portion, while the second side portion on the other side sandwiching the bent portion. A locking portion having a locking hole for inserting and locking the locking claw is projected from the outer surface of the bottom plate portion of the base plate, and the first side portion and the second side portion are directed outward with the thin hinge portion as a fulcrum. The locking claw can be rotated and locked in the locking hole, and the locking piece is inclined to the rotation direction so as to protrude, and the locking claw at the tip of the locking piece is on the opposite side to the rotation side. While the hypotenuse has a triangular cross-section that protrudes from the latching piece to form a latching surface, the latching hole has a rotation locus of the latching claw on the inner surface on the contact side with the counter-rotating side hypotenuse of the latching claw. The locking surface is locked to the periphery of the locking hole at a position where the locking claw that is inserted in sliding contact with the inclined surface of the locking hole protrudes from the locking hole. Above It provides a wire protector for harness, which comprises coupling holding the one side and a second side in an inclined position of the required angle.

The protector having the above structure is provided with a thin hinge portion serving as a bending fulcrum at the bottom plate portion of the protector body, and the first side portion and the second side portion that are bent at both sides of the thin hinge portion to be inclined are continuously provided. I have. A locked portion provided with a locking piece provided with a locking claw at the tip on the outer surface of the bottom plate portion of the first side portion, and a locked portion provided with a locking hole for locking the locking claw on the second side portion; After arranging the electric wire group in the protector body in a state where the bottom plate portion inner surface composed of the flat surfaces of the first side portion and the second side portion is continuously arranged in the horizontal direction, By bending the side plate and the bottom plate portion of the second side portion outward and inserting and locking the locking claw into the locking hole, the wire harness and the protector can be inclined at a required angle at the same time. .
In particular, the locking piece and the locked portion protrude from the outer surface of the bottom plate portion, not the side plate portion of the protector body, so that the wiring of the wire group is not affected and the locking piece and the locked portion are engaged. The joint part which consists of a stop part can be enlarged and joint force can be raised.

In the protector of the present invention, it is necessary to rotate the first side portion provided with the locking claw with the thin hinge portion as a fulcrum to the second side portion, and insert and lock it in the locking hole on the second side portion. . As described above, when the locking claw is rotated, if the amount of engagement of the locking surface of the locking claw to the locking hole is increased due to the problem of the rotation trajectory, the locking claw will pass when the locking claw passes through the locking hole. Since it is necessary to insert the locking claw while pressing it against the inner peripheral surface of the stop hole, there is a problem that a large insertion force is required and the deformation amount of the locking claw is increased.
For this problem, in the present invention, as described above, the locking piece protruding from the bottom plate portion of the first side portion to be rotated is inclined in the rotation direction, while the locking hole of the second side portion is locked. The inner surface on the contact side with the counter-rotating side of the claw is an inclined surface corresponding to the rotation trajectory of the locking claw. Therefore, even if the catching amount of the locking claw of the locking claw is increased, when the locking claw is inserted into the locking hole, the tip of the locking claw smoothly slides along the inclined surface to the locking hole. Can be inserted.
Therefore, even if the locking claw is protruded so as to increase the amount of the locking surface caught on the periphery of the locking hole, the insertion force of the locking claw into the locking hole can be reduced and the locking The deformation of the nail can be prevented, and the tilting posture of the protector can be reliably held by increasing the locking force while solving the problem during the locking operation.

  The rotation side of the locking claw of the locking piece is continuous with the straight surface of the locking piece, and the anti-rotation side oblique side is an inclined surface with an acute angle with respect to the locking surface, The inclination angle of the side is substantially the same as the inclination angle of the locking hole, and the inclination angle of the locking claw is preferably larger than the inclination angle of the locking piece with respect to the bottom plate portion.

  As described above, by making the inclination angle of the counter-rotating side of the locking claw substantially the same as the inclination angle of the locking hole, the counter-rotating side of the locking claw is substantially parallel to the inclined surface of the locking hole. Since it is inserted in the state, the locking claw can be smoothly inserted into the locking hole. In addition, by making the inclination angle of the locking piece larger than the inclination angle of the locking hole, the locking surface of the locking claw is moved to the locking hole when the locking claw is inserted into the locking hole. Can be securely locked to the periphery.

  The inclination angle of the locking piece with respect to the bottom plate portion is preferably 65 to 75 degrees, and particularly preferably 70 degrees. The inclination angle of the engagement claw at the tip of the engagement claw with respect to the bottom plate portion on the opposite side of the rotation claw is preferably 40 to 50 degrees, particularly preferably 45 degrees, and the inclination angle of the engagement hole is parallel to the angle. Is set. The angle difference between the inclination angle of the locking piece and the inclination angle of the counter-rotating side of the locking claw is preferably 20-30.

It is preferable that a plurality of locking pieces provided at the tip of the locking claw and a locking hole into which the locking claw is inserted and locked are arranged in parallel in the width direction of the bottom plate portion.
In the protector of the present invention, a locking piece provided with a locking claw at the tip from the outer surface of the bottom plate portion, and a locked portion provided with a locking hole for inserting and locking the locking claw are projected. Therefore, in the width direction of the bottom plate portion, 2 to 4 locking claws and locking holes can be provided according to the width direction dimension. It can be held securely.
In addition, it is preferable that the latched portions provided with the latching pieces and the latching holes of the latching claw project with the base portions in common to increase the strength of the base portions of the latching claws and the locking holes.

The protector according to the present invention includes lids that are attached to the first side portion and the second side portion of the protector body, respectively.
As described above, at least one of the first side part and the second side part lid is attached and bent in order to bend the bottom plate part outward after inserting the wire group into the protector body. It is sometimes preferable to prevent the wire group inserted through the protector body from protruding or detached from the protector body. In particular, when the side wall of the protector main body is low and shallow, it is preferable that one lid is attached and the wire group is securely accommodated in the protector main body.

As a method of attaching the protector to the wire harness,
Supported by a support rod erected from above the wire harness assembly table, the first side portion and the second side portion are placed in the horizontal direction continuously with the bottom plate portion of the protector body as the lower surface side,
Wire the wire group constituting the wire harness through the protector body,
After the wiring, the lid is attached to the first side part,
Next, the protector body is lifted upward from the support rod, and the bottom plate portions of the first side portion and the second side portion are bent downward with the thin hinge portion as a fulcrum, and the locking claws of the first side portion are rotated. The first side portion and the second side portion are coupled and held in a tilted posture of a predetermined angle by being inserted and locked in the locking hole.
Then, the protector attachment method to the wire harness characterized by attaching the lid | cover to the 2nd side part is provided.

According to the above mounting method, the protector that needs to be bent to follow the wiring path of the wire harness is held horizontally on the wire harness assembling table. Therefore, the electric wire group which comprises a wire harness can be wired continuously without a height difference in a horizontal direction, and wiring workability | operativity can be improved. And after passing the wire group through the protector body and laying it in the horizontal direction, after attaching the lid to the first side part, it is rotated and inclined with respect to the second side part, and the engaging claw is inserted into the engaging hole. If locked by locking, the protector body and the wire harness can be bent at the same time and can be held in an inclined posture along the wiring direction as required.
In this way, on the wire harness assembly worktable, the protector body can be wired while being held in a horizontal position. And the protector can be easily inclined at the same time in accordance with the wiring direction of the wire harness.

  As described above, according to the protector of the present invention, the bottom plate portion of the protector main body is provided with the thin hinge portions in the direction orthogonal to the wiring direction of the electric wire group and is continuous, and the first side portions on both sides of the thin hinge portions are provided. By projecting a locking piece provided with a locking claw at the tip and a locked portion provided with a locking hole for locking the locking claw on the outer surface of the bottom plate part of the second side part, After arranging the wire group constituting the wire harness in the protector body in a state where the inner surface of the bottom plate portion composed of the flat surfaces of the first side portion and the second side portion is arranged in a continuous horizontal direction, By bending the bottom plate portion of the two side portions outward and inserting and locking the locking claw into the locking hole, the wire harness and the protector can be simultaneously inclined at a required angle.

  Further, it is necessary to rotate the locking claw and insert it into the locking hole, but if the locking claw provided with the locking claw to be rotated and the locking hole are inclined corresponding to the rotation locus, The tip of the locking claw is inclined to the inner surface of the locking hole when inserted into the locking hole, even if the locking surface is enlarged to increase the amount of locking of the locking surface of the locking claw to the locking hole. It can be inserted while sliding smoothly without pressing strongly against the surface. Therefore, it is possible to increase the amount of hooking of the locking surface while reliably reducing the insertion force, and it is possible to reliably hold the inclined posture.

  According to the protector mounting method to the wire harness of the present invention, the protector that needs to be bent in accordance with the wiring posture of the wire harness, the first side portion and the second side portion of the protector main body on the wire harness assembly table. Can be continued horizontally. Therefore, the electric wire group which comprises a wire harness can be wired continuously in a horizontal direction, and wiring workability | operativity can be improved. In addition, after the wire group is laid out, the wire harness and the protector are routed in the vehicle at the same time by simply rotating the first side of the protector body and locking it to the second side. It is easy to convert and hold the bent posture corresponding to the above.
