Abstract

A cable protection and guide device, wherein: the warp in front and rear side portions of link plates in the width direction is reliably limited so that an inadvertent disengagement between the link plates is completely blocked. The connection between the link plates is easy and manufacturing of the link plates is easy. Short arc-shaped warp limiting lock grooves are formed along a path coaxiallyspaced from a connecting pin or a connecting pin hole. Short arc-shaped warp limiting lock pieces are fitted to the short arc-shaped warp limiting lock grooves in a concave element / convex element engagement opposed surfaces of the link plates connected in the longitudinal direction so that warping in the front and rear side portions of the link plates in a width direction is limited.

Description

technical field

[0001] The present invention relates to safe and reliable protection and guidance of electric cables for power supply, signal transmission, etc., used in industrial machines such as machine tools, electronic equipment, industrial robots, and conveying machines, etc. Cable protection and guide devices for flexible cables such as oil pressure hoses, air pressure hoses, and optical fiber cables. Background technique

[0002] Conventionally, as such a cable protection and guide device, there is an energy supply chain for accommodating cables, pipes, etc.: the chain member is formed in a box shape, and plugs and circular openings are alternately provided on the side wall. The plug of the chain member fits into the opening of the next chain member and the relative rotational movement of the successive chain member is restricted by the stopper 511 of the side wall portion of the successive chain member (for example, refer to Patent Document 1).
