Abstract

<P>PROBLEM TO BE SOLVED: To reduce the number of part items and assembly man-hours and to reduce manufacturing cost. <P>SOLUTION: A guide link (1) is obtained by connecting a pair of confronted side boards (1C) by a coupling part (1B) on an upper face. A long and integrally formed component where a plurality of guide links (1) are connected and gaps (1A) are formed between the adjacent side boards (1C) is constituted. A slide strip (2) having band-like flexibility is integrally formed. The slide strip (2) is fitted between the side boards (1C) of the intermediate guide link (1) so that it can slide in a longitudinal direction, and is fixed to the guide links (1) at both ends so as to constitute a cable guide.

Description

  The present invention relates to a cable guide, and more particularly, a guide that protects and guides a power supply cable that supplies power from a stationary device to a reciprocating device, or a signal cable that transmits and receives a signal so as to be slidable in the longitudinal direction. A cable having a link, one end of the guide link being connected to the stationary device, the other end being connected to the reciprocating device, and absorbing the extra length of the cable generated by the reciprocating motion by the revolving structure of the guide link Regarding the guide.

As a conventional cable guide that can be used flexibly for a cable to be guided, one shown in FIGS. 5 and 6 is known (see Patent Document 1). In FIG. 5, the guide link 100 is fixed on the slide strip 101, and the guide link 100 has a guide channel 102 for holding the cable A. In FIG. 6, the guide links 100 have a structure (indicated by reference numeral B) in which the guide links 100 are fitted to each other and a structure (indicated by reference numeral C) that restricts the angle at the time of turning. It is configured to function.
JP 2002-534950 A

  Since the conventional guide link 100 functions as a cable guide by connecting a plurality of guide links 100, the number of parts is increased, the assembly work of the individual guide links 100 is required, the assembly man-hours are also increased, and the manufacturing cost is increased. It was something that would end up.

  Moreover, since the guide link 100 requires a fitting structure for connecting each other and a structure for limiting the turning angle, the structure of the resin molding die becomes complicated and the die becomes expensive. It was a thing.

  An object of the present invention is to provide a cable guide that is simple in structure, low in mold cost, and easy to assemble.

  In order to achieve the above-mentioned object, the present invention is a long, integrally molded structure in which a large number of guide links are connected by connecting a pair of opposing side plates with connecting portions on the upper surface, and a gap is formed between the adjacent side plates. In addition to forming a strip-shaped flexible slide strip, the slide strip is attached between the side plates of the intermediate guide link so as to be slidable in the longitudinal direction, and the guide links at both ends are formed. The cable guide is configured by being fixed to the cable guide, and the free ends of the adjacent side plates are brought into contact with each other when the cable guide is pivoted so as to limit the pivot angle.

  According to the present invention, a large number of integrally formed parts are formed in which a large number of guide links are formed by connecting two pair of side plates facing each other by connecting portions on the upper surface, and gaps are formed between adjacent side plates. A strip-shaped flexible slide strip is integrally molded, and the slide strip is attached between the side plates of the intermediate guide link so as to be slidable in the longitudinal direction thereof, and is fixed to the guide links at both ends and is fixed to the cable guide. Since the rotation angle is limited by contacting the free ends of the adjacent side plates when turning the cable guide, a plurality of slide strips are used when turning the cable guide accompanying the reciprocating motion of the reciprocating device. Because it slides in the longitudinal direction inside the whole connected guide link, the swivel part that occurs when the cable turns It can absorb the difference between the periphery and the inner periphery of the deformation length. In addition, since the length of the cable guide and the length of the slide strip are always constant, a stable cable trajectory can be obtained by the shape retention force. Further, the space for storing the cable to be guided is composed of two basic parts, that is, a guide link and a slide strip, so that the assembling work of the turning portion is not necessary.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  In the embodiment of the invention shown in FIG. 1, both the guide link 1 connected and the strip-like flexible slide strip 2 are both long and continuous integrally molded resin molded products. The plurality of guide links 1 have a U-shaped cross section, a gap 1A is formed between adjacent guide links 1, all the guide links 1 are connected to each other on the upper surface (connecting portion 1B) on the drawing, and a resin material It is integrally molded with.

  FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and the slide strip 2 is inserted into the inner surfaces of a pair of side plates 1 </ b> C facing each other of each guide link 1 to attach the slide strip 2 to the guide link 1. Two pairs of protrusions 10 and 11 are formed for the purpose. The slide strip 2 is inserted or squeezed into the gap between the protrusions 10 and 11.

  FIG. 3 is a perspective view before the slide strip 2 and the guide link 1 are attached. The slide strip 2 is sandwiched between the protrusions 10 and 11 formed on the inner surface side of the side plate 1C of each guide link 1. The slide strip 2 can be bent and slid in the longitudinal direction without being restricted by the guide link 1. The slide strip 2 is not fixed by the protrusions 10 and 11 but has an attachment structure in which the slide strip 2 is only caught between the protrusions 10 and 11. The slide strip 2 is attached between the projections 10 and 11 by sliding the slide strip 2 in the longitudinal direction and inserting the slide strip 2 between the projections 10 and 11 and opening the pair of side plates 1C of the guide link 1. It is possible to squeeze both sides of the slide strip 2 between the projections 10 and 11. When disassembling, the slide strip 2 can be easily removed from the guide link 1 by the opposite operation.

  FIG. 4 is a front view of a state where the cable guide is turned. The limitation of the turning angle is not required for a special structure (see reference numeral C in FIG. 6) as in the prior art, and is performed when the free ends of the adjacent side plates 1C of the guide links 1 come into contact with each other. In FIG. 4, the gap 1A on the free end side of the side plate 1C disappears, and the free ends of the adjacent side plates 1C collide with each other, preventing further turning of the cable guide. A contact portion between the free ends is indicated by a symbol X. Note that both ends of the guide link 1 and both ends of the slide strip 2 are fixed by fastening means 12.

4, the overall length of that connecting guide link 1, which was the length L ₁ of the cable guide, the length of the slide strips 2 and L _2, when the turning radius was R _1, Ya their length The diameter is set according to the moving distance of the reciprocating device to which the cable guide is attached, the distance between the reciprocating device and the stationary device, the flexibility of the cable to be guided, and the like.

  In addition, the cable guide of this invention can also be utilized for the cable routing part which connects the motor vehicle body and door of a motor vehicle having a slide door. Further, when the protrusions 10 and 11 are formed on the inner surface of the side plate 1C of the guide link 1 and the gap between them is made substantially the same as the thickness of the slide strip 2, the slide strip 2 is sandwiched between the protrusions 10 and 11, Although the slide strip 2 is slidable in the longitudinal direction, a long groove may be formed in the side plate 1C instead of the protrusions 10 and 11, and the slide strip 2 may be fitted into the long groove. In any case, the projections 10 and 11 are not limited as long as the entire structure connecting the plurality of guide links 1 can be integrally molded with a resin material.
