Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a holding device for holding bar-shaped materials such as cables, wires, pipes, etc.

(Prior art) This type of holding device includes, for example,
The one published in Publication No. 133179 is known. This item is for holding heater control cables in automobiles. For holding work, first set the cable on the base material side. Under this condition, by fitting and engaging the locking claw of the separately provided locking body into the locking hole of the base body, the cable is prevented from slipping in the axial direction and from coming off.
This will be done together.

(Problem to be solved by the invention) However, since the above cable is held by a combination of the base and the locking body, the locking body must be prepared separately. This will lead to cost improvements. At the same time, there were problems such as poor workability due to the necessity of assembling the locking body.

Therefore, the present invention aims to provide a holding device that can reduce costs and improve workability.

(Means for solving the problem) The above objective is achieved as follows. That is, the present invention provides a rod-shaped material having an annular groove recessed in a part of its outer circumferential surface, and a base body that receives the rod-shaped material includes a pair of clamps into which the rod-shaped material can be inserted from the side, and a pair of clamps in which the rod-shaped material can be inserted from the side; The structure is such that a slip-stop piece is formed that elastically engages with the bar-shaped member to prevent it from slipping in the axial direction.

(Operation and effect of the invention) Therefore, according to the above structure, when the bar-shaped member is inserted into the clamp pair from the side and the groove portion and the anti-slip piece are elastically engaged, the bar-shaped member can be inserted into the clamp pair from the side. can be held securely without shifting in the axial direction. Further, unlike in the past, there is no need to use a dedicated holder such as a locking body to hold the rod-shaped material, so it is possible to reduce costs and simplify the work process.

(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings. However, this example device is for holding a heater control cable C of an automobile.

First, this cable C will be explained. The cable C consists of a core wire w and a tube t that is loosely inserted and covered with the core wire w. The core wire w is
Both ends thereof are exposed for a predetermined length range from the tube t, one end of which is connected to an operating lever L for controlling the heater, and the other end connected to a corresponding air conditioning mechanism. Further, at a predetermined position near the end of the cable C on the operating lever side, a groove tm is formed by cutting the outer peripheral surface of the tube t into an annular shape.

Now, 1 in the figure is a mounting base fixed to a predetermined position of the automobile. As shown in FIG. 1, a circular base body 2 is integrally formed on a part of the upper surface of the mounting base 1 from a synthetic resin material.

A pair of left and right clamps 3 are provided on the upper surface of the base body 2.
f, 3r are erected at a predetermined interval in front and back. Each pair of clamps 3f, 3r has an inner circumferential surface shaped like a tube t so that the cable C can be press-fitted from the side thereof and can be held tightly.
It is formed in an arc shape along the outer peripheral surface of. Therefore, although a slight elastic deformation in the expansion direction due to the press-fitting of each clamp pair 3f, 3r and cable C is allowed, the cable C is
It does not undergo elastic deformation to the extent that it widens the space between 3r and escapes upward.

Further, both clamp pairs 3f, 3 are provided on the upper surface of the base 2.
A receiving groove surface 4 for receiving the cable C is formed in each outer portion on the same line as r, and has a U-shaped cross section. Of the two receiving groove surfaces 4, the one on the near side shown in FIG. 1 has its front end surface serving as a positioning stop surface 5 against which the tube t of the cable is abutted.

Furthermore, a recess 6 is provided between both clamp pairs 3f and 3r, which is wider and deeper than the receiving groove surface 4. A pair of left and right anti-slip pieces 7, which are elastically deformable in the expansion direction, are provided in the recess 6 in parallel with the pair of clamps 3f, 3r. Both anti-slip pieces 7 are opposed to each other with a width slightly narrower than the outer diameter of the groove tm of the cable C, and by elastically holding the groove tm,
It is possible to prevent the cable C from shifting in the front-back direction.

The opposing distances (distances) between the pair of clamps 3f, 3r and the anti-slip piece 7 are each set to be slightly larger than the outer diameter of the core wire w. In other words, each pair of clamps 3f, 3r is allowed to undergo slight elastic deformation in the expanding direction due to the press-fitting of the cable C, but only to the extent that the cable C can widen the gap between the pair of clamps 3f, 3r and come out upward. It does not undergo elastic deformation.

Subsequently, the functions and effects of this example formed as described above will be specifically explained.

First, while tilting the entire cable C, insert the tip of the core wire w into the insertion hole h of the operating lever L. Next, the cable C is fixed to the base 2 in order to position it. In this case, the tube t is shifted backward in advance to expose the core wire w by a predetermined length. In this state, the cable C is rotated to a horizontal position, and the core wire w exposed as described above is placed between the clamp pairs 3f, 3r and the anti-slip piece 7, respectively. After this, in order to return the tube t, first place it between the pair of clamps 3f on the far side shown in FIG.
Push the tube in while expanding it, and then press the end surface of the tube t against the stopper surface 5 through the pair of clamps 3f on the front side in the figure. By doing this, the tube t is positioned, and when the groove tm of the tube t matches the anti-slip piece 7,
The anti-slip piece 7 returns to engage with the groove tm. Therefore, displacement of the tube t in the front-back direction is restricted. In addition, since both clamp pairs 3f and 3r do not easily expand and deform, the cable C does not come off upward and can be held securely.

As described above, according to this example, the cable C is held only by the members provided on the base body 2 side, such as the clamp pair 3f, 3r and the anti-slip piece 7, which is different from conventionally used members. This eliminates the need for a dedicated locking body, which reduces manufacturing costs, and eliminates the need to assemble the locking body, thereby improving work efficiency.

Note that the number of clamp pairs 3f and 3r is not limited to two as in this example, and the periphery of the anti-slip piece 7 on the push-in side of the tube t may be chamfered to facilitate the push-in operation. be.
