[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt plate-like harness clip detent structure which is fastened and fastened by a single screw member and is bendable so as to bundle harnesses.

[0002]

2. Description of the Related Art Conventionally, for example, in a control valve of an automatic transmission for a vehicle, wiring for attaching a harness of electrical equipment such as a solenoid and an oil temperature sensor to an upper valve body B1 and a lower valve body B2 (attached body) of the control valve. The harness clip 1 as shown in FIGS. 4 and 5 is used as a component for the vehicle. The harness clip 1 has a fastening portion 2 and a strip-shaped portion 3 formed so as to extend integrally from the fastening portion 2. The fastening portion 2 is provided with a detent claw 4 for preventing rotation. A protective member 5 for protecting the harness is inserted through the strip-shaped portion 3.

In this case, the fastening portion 2 has a shape like a thin plate ring-shaped washer except for the claw 4.
The shaft portion of one screw member 6 can be inserted, and this screw member 6 is inserted into the through hole 7a of the fixed seat 7 formed in the lower valve body B2 to form the screw hole formed in the upper valve body B1. It is fixed to these bodies B1 and B2 (attached bodies) by being screwed in (not shown in FIG. 5). Further, the strip-shaped portion 3 can be normally bent easily by human power, and thus the harness H is bundled as shown in FIG.

In the control valve of the automatic transmission, as shown in FIG. 5, the upper valve body B1 and the lower valve body B2 are usually connected and fixed by the screw member 6. That is, in this case, the shaft portion of the screw member 6 is screwed into the screw hole (not shown in FIG. 5) formed in the upper valve body B1 while penetrating the through hole 7a formed in the lower valve body B2. In rare cases, the bodies B1 and B2 are fixed to each other.

Further, the claw 4 formed on the fastening portion 2 is projected downward on the side surface of the boss-shaped fixed seat 7 formed in a protruding state on the surface of the lower valve body B2 (attached body). It is shaped like a hook. On one side of the fixed seat 7, there is provided a ridge 7b with which the side surface of the claw 4 abuts.
Formed to extend laterally from the side of the
The harness clip 1 is prevented from rotating by the abutment of the ridge 7b with the ridge 7b.

That is, the screw member 6 is inserted into the through hole 7a and screwed in to fasten the fastening portion 2 on the fixed seat 7, thereby connecting the bodies B1 and B2 and fixing the harness clip 1. When trying, the harness clip 1 works in the tightening direction of the screw member 6 (in this case, the clockwise direction) by the frictional force between the head seat surface of the screw member 6 and the surface of the fastening portion 2. There is a possibility that it will rotate against the wishes of a person, and if there is no mechanism to prevent this, it will be difficult to fix the harness clip 1 in a predetermined posture. Therefore, conventionally, the above-mentioned claw 4 and the ridge 7 are conventionally used.
The rotation stop structure by b was provided.

The protective member 5 is made of a material having flexibility so as not to damage the harness H, for example, rubber or synthetic resin, and is inserted through the strip plate-like portion 3 of the harness clip 1 from the tip side to cover it. For example, as shown in FIG. 4, it is a bag-shaped member that also covers the front end surface of the strip-shaped member 3.

[0008]

The conventional detent structure for the harness clip 1 has the following problems to be improved. (1) As much as the claws 4 that are bent downward are arranged,
Since it is necessary to increase the height of the fixed seat 7 and the length of the screw member 6 is also long, it becomes an obstacle to downsizing and an increase in cost. (2) If the claw 4 is shortened to solve the above problems,
The strength of the harness clip may decrease and the harness clip may deform during fastening.To prevent this, it is necessary to use a material with high rigidity as the material of the harness clip or to increase the thickness of the harness clip. In the case of, the cost will still increase. Further, in this case, there is a problem that the strip plate-shaped portion of the harness clip becomes difficult to bend, and the workability of the work of bundling and mounting the harness is deteriorated.

(3) In order to form the hook-like claw 4 extending from the fastening portion 2, a large amount of extra material is required and the manufacturing process of the harness clip becomes complicated. That is, the main body portion (the portion excluding the protective member 5) of this kind of harness clip is usually manufactured by punching from a flat plate by press working, but the claw 4 is punched out in an expanded shape. Later, it is necessary to form a part by bending. Therefore, the cost of manufacturing such a harness clip is high.

Therefore, it is a primary object of the present invention to provide a harness clip rotation-preventing structure realized with a smaller size and lower cost.

[0011]

In order to achieve the above object, in the harness clip rotation preventing structure according to claim 1, a shaft portion of one screw member can be inserted, and the harness member is secured by the screw member. A harness clip having a fastening portion that is fastened and fixed to an attached body to be attached, and a band plate-shaped portion that extends from the fastening portion and is bendable so as to bundle the harnesses. The harness clip is brought into contact with a convex portion formed by processing so that a part of the clip plate portion on the fastening portion side projects to the surface, and a side surface position of the convex portion of the strip plate portion. wherein for blocking the rotation of said threaded member tightening direction and a contact portion formed on the mounting member, the contact portion

It is for the purpose of doing.

Further, in the harness clip rotation preventing structure according to a second aspect of the present invention, a protective member having flexibility for protecting the harness is inserted from the front end side and covered on the surface of the strip-shaped portion. The convex portion is formed at a position in contact with the end surface of the protective member,
It is characterized in that it functions as a guide for surely letting the operator recognize the insertion end position of the protective member.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION An example of an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a honey clip of this example and its peripheral structure, and FIGS. 2 (a) and 2 (b) respectively show a mounted state of the honey clip of this example (control valve of an automatic transmission). And FIG. The same components as those of the conventional example shown in FIGS. 4 and 5 are designated by the same reference numerals, and duplicate description will be omitted.

The harness clip 11 of this embodiment has a fastening portion 12 in which the claw 4 is not formed as in the prior art, and a convex portion 14 extending from the fastening portion 12 toward the base end side (the fastening portion 12 side).
And a strip-shaped portion 13 formed with. Here the convex part 1
No. 4 is formed by press working so that a part of the base end side of the strip plate-shaped portion 13 protrudes to the upper surface side in a circular dome shape. Further, in this case, the convex portion 14 is formed at a position where it comes into contact with the end surface of the protection member 5, and thereby functions as a guide for making sure the operator recognizes the insertion end position of the protection member 5.

The fixed seat 17 of this embodiment is formed to have a minimum height necessary for forming a seat surface, and one side surface of the fixed seat 17 has a side surface of the convex portion 14 of the strip plate portion 13. A protrusion 18 (contact portion) that contacts the position is formed. Then, the screw member 6 of this example for fixing the harness clip 11
a is a fixed seat 17 as compared with the conventional screw member 6 described above.
The shaft length is shortened by the lower height of.

In the case of this embodiment, the height of the upper surface of the protrusion 18 is inserted into the through hole 17a so that the harness clip 1
It is set to be lower than the head upper surface height of the screw member 6 in the state where 1 is fastened. Further, in this case, as shown in FIG. 2A, the upper valve body B1 and the lower valve body B2 are connected and fixed by the screw member 6a. That is,
In this case, the shaft portion of the screw member 6a also has a lower valve body B.
The body B1 and B2 are fixed to each other by being screwed into the threaded hole 17c formed in the upper valve body B1 while penetrating the through hole 17a formed in No. 2.

According to the harness clip and its peripheral structure of the present embodiment, the detent at the time of fastening the harness clip can be realized with a compact and low-cost structure. That is, when the harness clip 11 is attached in a predetermined posture and fastened by the screw member 6a, as shown in FIG. 2, the protrusion 18 formed on the lower valve body B2 (attached body) has the strip plate portion 1 formed thereon.
It contacts the side surface position of the convex portion 14 in 3, and rotation of the harness clip 11 in the tightening direction is prevented.

Moreover, in this example, since the member such as the conventional claw 4 is not provided, the height of the fixed seat 17 can be set significantly lower than the conventional one, and the axial length of the screw member 6a can be reduced. . Further, since the convex portion 14 plays the role of a reinforcing rib, even when an inexpensive and thin plate material is used as the material of the harness clip 11, the deformation at the time of fastening can be prevented. Further, since there is no portion that needs to be largely overhanged and bent unlike the conventional nail 4, the manufacturing process of the harness clip 11 is reduced, the productivity is improved, and the required material is reduced.

In the case of this example, the convex portion 14 is formed at a position where it comes into contact with the end face of the protective member 5, and it can be used as a guide for making sure the operator recognizes the insertion end position of the protective member 5. Since it is functioning, there is an inherent effect that the insertion work of the protection member 5 is facilitated while the cost is kept low, and the risk of a work error of the insertion work is significantly reduced. Further, in the case of this example, since the upper surface height of the projection 18 is set lower than the head upper surface height of the screwed-in screw member 6, it is projected higher than the head portion of the screw member 6 on the surface. The number of parts to be used is reduced, and in this respect as well, downsizing as a whole is realized.

It should be noted that the present invention is not limited to the above-mentioned form example, and various modes and modifications may be possible. For example, the convex portion formed on the strip-shaped portion of the harness clip according to the present invention is not limited to the mode such as the circular dome-shaped convex portion 14 in the above-described embodiment, and for example, the convex portion as shown in FIG. 24 is a strip-shaped portion 23
The harness clip 21 formed in the above may be used. The convex portion 24 shown in FIG. 3 is formed by curving in a mountain shape so that a part of the base end side of the strip plate portion 23 is projected to the upper surface. Therefore, it can be easily processed with a small amount of material.

[0021]

In the harness clip rotation preventing structure according to the first aspect of the present invention, the convex portion is formed by processing so that a part of the harness clip band plate-shaped portion on the fastening portion side projects to the surface. The abutting portion formed on the attached body abuts on the side surface position of the convex portion of the strip plate portion, and rotation of the harness clip in the tightening direction is prevented.

Therefore, the detent at the time of fastening the harness clip can be realized with a compact and low-cost structure. That is, in the present invention, since the conventional member such as the claw is not provided, the height of the fixed seat of the mounted body can be set significantly lower than that of the conventional one, and the axial length of the screw member can be reduced. Further, since the convex portion plays a role of a reinforcing rib, it is possible to prevent deformation at the time of fastening even if an inexpensive and thin plate material is used as a material for the harness clip. Furthermore, since there are no parts that need to be overhanged and bent like the conventional nails,
The harness clip manufacturing process is reduced, productivity is improved, and less material is required.

Further, the harness clip according to claim 1
In the rotation prevention structure, the height of the upper surface of the contact portion is
