Tube type cable protection and guide device

Abstract

A tube type cable protection and guide device in which the device can be easily manufactured by extrusion molding without changing the size of a mold so that devices of different lengths can be made. Smooth linear and flexional movements can be made while sufficiently ensuring dimensional stability and torsional rigidity of the device thus assuring stability of the cable accommodating space. A tube type cable protection and guide device includes integrally molded inner circumferential wall forming portions. The inner wall forming portions are interdigitatedly fitted in a male-female relationship in a longitudinal direction of the sheet forming a flush inner flat surface.

Description

Technical field [0001] The present invention relates to a cable protection and guide device, and more specifically, to a device suitable for housing such as semiconductor manufacturing equipment, pharmaceutical testing equipment, vehicle door opening and closing devices, vehicle sliding seats, vehicle electric sunshades, etc. Lightweight and small-diameter cables such as cables or hoses that supply power or compressed gas energy to movable parts, and guide and protect cables safely and reliably even when the movable parts are moving Class protection guiding device. Background technique [0002] As a conventional cable protection and guide device, it is known that the upper edge portion and the lower edge portion of a pair of link plates of the same shape that are separated and opposed are connected by a fin and a bottom plate used as a coupling member. Cable / hose protection guide chain (for example, refer to Patent Document 1). [0003] In addition, there is known a foldable prot...

AI Technical Summary

Problems solved by technology

[0006] However, in the protective guide chain described in Patent Document 1, it is necessary to reliably connect a plurality of link plates, the fins and the base plate as its connecting parts along the length direction of the cable, and the complicated assembly structure is cumbersome, and There is also the problem of not being able to avoid its huge manufacturing burden

[0007] In addition, since the foldable protective element described in Patent Document 2 is injection molded or molded in one piece, if it is desired to manufacture a wide size or a long structure, there are also physical limitations on the size of the metal mold, Manufacturing conditions such as temperature control of the mold and the cost of the mold are limited, and there is a troublesome problem in the mold that the structure of the elongated body cannot be easily manufactured. In addition, there is a need to assemble the segments for bonding one by one. Troublesome problem in manufacturing
