Abstract

PROBLEM TO BE SOLVED: To obtain a cable holder which is capable of holding a cable and at the same time keeping the interval from other parts constant so as not to bring it into contact with them independently of its length, size, torsion, bending and the like. SOLUTION: A cable holder 11 is a plastic molded body equipped with a spiral holder 11a which spirally twines around a cable 12 to be able to hold it and a rod-shaped space retainer 11b integratedly joined to the center of the holder 11a at a right angle to the center. The holder 11a is twined around the cable 12, and the tip 11c of the spiral space retainer 11b is fixed to a part 13 such as a chassis. As the cable 12 is held with the spiral holder 11a, it can be tightly held even if it is slightly thin in outer diameter, and the spiral holder 11a is able to effectively curb the cable 12 holding its certain part specified in length. Therefore, the cable 12 can be held by the cable holder 11 as kept at a constant interval from the part 13 which is desired to be kept separate from the cable 12 by a certain distance independently of its length, size, torsion, bending and the like.

In the cable holder 1 shown in FIG. 3, the length of the cable 3 (the length of the range to be restrained).
Is short, and when the hole diameter of the holding portion 2a that closes in an annular shape appropriately corresponds to the outer diameter of the cable 3 and the cable 3 is gripped tightly, the cable 3 is effectively restrained, so one cable holding It is also possible to maintain the distance from the non-contact component 4 with the tool 1. However, when the length of the cable 3 becomes long or the outer diameter becomes small, if the same cable holder 3 is used, the cable 3 cannot be effectively restrained, so that only one cable holder 3 is used. Three
May contact the non-contact component 4. Further, even if the hole diameter of the holding portion 1a appropriately corresponds to the outer diameter of the cable 3, if the cable 3 is twisted or bent, one cable holder 3 still effectively restrains the cable 3. If this is not possible, the cable 3 may come into contact with the non-contact component 4. For this reason, conventionally, in order to maintain the distance between the cable 3 and the non-contact component 4, a plurality of cable holders 1 are usually used.
Was used.

The same holds true for the cable holder 2 shown in FIG. 4, and one cable holder 2 cannot effectively restrain the cable 3 depending on the length, thickness, twisting, bending, etc. of the cable 3. Therefore, conventionally, a plurality of cable holders 2 are usually used to maintain the distance between the cables 3.

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and holds the cables, and determines the distance between the cables and the parts adjacent thereto or the distance between the cables, such as the length, thickness and twist of the cables. An object of the present invention is to provide a cable holder that can be reliably maintained by one or a few cable holders regardless of bending or bending.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the first invention and the second invention will be described below with reference to the embodiments shown in FIGS. FIG. 1 shows an embodiment of the cable holder 11 of the first invention. The cable holder 11 holds a cable 12 and maintains a constant gap between the cable 12 and a component (hereinafter, referred to as a non-contact component) 13 such as a chassis which is not desirable to bring the cable 12 into contact with each other. A spiral holding portion 11a that can be wound around the cable 12 in a spiral shape to hold the cable 12; and a rod-shaped distance maintaining portion 11b that is integrally connected at a right angle to the center of the spiral holding portion 11a. And the overall shape is approximately T-shaped (T-shaped when the spiral portion is regarded as a straight line), and the space maintaining portion 11 is provided.
The tip of b is fixed to the non-contact part 13 adjacent to the cable passage position. The fixing means of this embodiment has a structure in which a bulging portion 11c that elastically expands and contracts is formed at the tip of the space maintaining portion 11b, and an inwardly extending recess 13a that accommodates the bulging portion 11c is formed on the non-contact component 13 side. is there. At the time of attachment, if the enlarged portion 11c at the tip of the space maintaining portion 11b is pushed into the inwardly widened recess 13a, the enlarged portion 11c contracts and expands inside after passing through the inlet, and the inwardly widened concave portion is prevented from easily coming off. It is fixed in place 13a. The means for fixing the tip of the spacing maintaining portion 11b to the adjacent non-contact part 13 is not limited to the example shown in the figure. For example, in FIG. 1, the other side with which the enlarged portion 11c at the tip engages is as shown in the figure. It is also conceivable that it is a mere through hole formed in a thin flat plate portion instead of an inwardly extending recess. Further, in the case of the mere through hole, a screw may be formed at the tip of the space maintaining portion 11b instead of the enlarged portion, and the screw may be tightened and fixed with a nut. The cable retainer 11 is suitably made of plastic. The molding can be performed by injection molding or the like.

With the above cable holder 11, the cable 1
In the case of holding 2, the spiral holding portion 11a of the cable holder 11 is spirally wound around the cable 12, and then the distance maintaining portion 11b is attached to the inner spreading recess 13a of the non-contact component 13 or vice versa. It can be done by the procedure. When the cable 12 is held by the cable holder 11, the spiral holding portion 11a holds the cable 12, so that the cable 12 can be held tightly even if the outer diameter of the cable 12 is slightly reduced. Therefore, the cable 12 can be effectively restrained. Further, since the spiral holding portion 11a holds the fixed length range of the cable 12, the cable 12 can be effectively restrained also in this respect. Therefore, even if the cable 12 is twisted or bent, the holding portion 11a does not
The cable 12 can be held in a desired position by correcting its twisting and bending. In this way, the distance between the cable 12 and the non-contact component 13 can be maintained while holding the cable 12 regardless of the length, thickness, twist, and bending of the cable 12. In FIG. 1, reference numeral 14 denotes a component such as a chassis which is not desirable to contact the cable 12 with, and the distance to the component 14 is also kept constant.

FIG. 2 shows an embodiment of the cable holder 21 of the second invention. This cable holder 21 is for keeping the distance between the two cables 12 constant, and is a pair of spirals facing each other that can be wound around each of the two cables 12 in a spiral shape to hold each cable 12. And a bar-shaped distance maintaining portion 21b that is integrally provided between the pair of holding portions 21a and that maintains the distance between the two holding portions 21a. H-shaped when viewed as a straight line: In the figure, it is horizontal H).

In this cable holder 21, as shown in the figure, when two spiral holding portions 21a are respectively wound around the cable 12, the cable 12 is held by the holding portions 21a while the space maintaining portion 21b is used. The distance between the twelve is kept constant.

The spiral holding portion 11a of the cable holder 11 of the first invention and the spiral holding portion 21a of the cable holder 21 of the second invention are both
Although the whole has a spiral shape with the same direction, for example, it may have a symmetrical spiral shape (a shape in which the direction of the spiral is reversed at the center) about the space maintaining portion 11b or 21b. In addition, the spacing maintaining portions 11b and 21b are the holding portions 11 having a spiral shape.
Although it is suitable to provide it in the center of a, 21a, it is not necessarily limited to the center, and it may be integrally connected at a biased position or an end. In addition, the cable holders 11 and 21
Not only the chassis but also the cable 12
It is possible to target any component which is not desired to be in contact with.

[0014]

According to the present invention, the distance between the cable and the adjacent parts or the distance between the cables can be set to one or a small number of cable holders regardless of the length, thickness, twisting, bending, etc. of the cables. It can be maintained reliably. Thus, the quality and reliability of the function of holding the cable are improved, and the workability of holding the cable by the cable holder is also improved. Further, since the structure of this cable holder is simple, this excellent component can be provided at low cost.
