Cable protection and guide device

Abstract

Breakage in a coupling portion of a side plate subjected to repeated flexure is prevented by using fatigue resistant resin materials in the side plate. The coupling portion of the side plate due is subjected to repeated flexure. Excellent fatigue resistance is realized. The fatigue resistant resin material is selected from the group of an elastomer- or rubber component- compounded polyamide resin and polybutylene terephthalate resin. The rubber component is selected from the group of ethylene-propylene rubber (EPDM), nitrile rubber (NBR) and butyl rubber (IIR).

Claims

1. A cable protection and guide device, comprising: a number of pairs of right and left side plates spaced apart from each other; each of said side plates include inner circumferential sides and outer circumferential sides; said pairs of side plates are connected to each other in a longitudinal direction; connecting arms; said connecting arms are bridged over flexional inner circumferential sides at predetermined intervals; said connecting are bridged over said flexional outer circumferential sides at predetermined intervals; a cable is accommodated in a cable accommodating space surrounded by said side plates and said connecting arms along said longitudinal direction; each of said side plates is molded by use of a fatigue resistant resin material and is formed of a front side plate portion connected to a preceding side plate; a rear side plate portion connected to a subsequent side plate and an integral flexible coupling portion interposed between said front side plate portion and said rear side plate portion.

2. A cable protection and guide device according to claim 1, wherein said fatigue resistant resin material is selected from the group of an elastomer- or rubber component- compounded polyamide resin and polybutylene terephthalate resin.

3. A cable protection and guide device according to claim 2, wherein in said elastomer is styrene-ethylene-butylene-styrene (SEBS).

4. A cable protection and guide device according to claim 2, wherein in said rubber component is selected from the group of ethylene-propylene rubber (EPDM), nitrile rubber (NBR) and butyl rubber (IIR).
