Problems solved by technology

[0006] However, in the above-mentioned conventional cable protection and guide device 500, the pair of left and right side plate portions 510A, 510B each have a shape having three parts, the front side plate portion 511, the rear side plate portion 512, and the joint 513. Therefore, the side plate parts 510A and 510B are formed into complex shapes, which increases the manufacturing burden including molds.
[0007] In addition, since the side plate portions 510A and 510B are different parts independent of each other, it takes a lot of labor to connect them into a long strip shape, which is a labor force equal to the number of the side plate portions, which imposes a heavy burden on the assembly work.
[0008] Furthermore, the left and right pair of side plate parts 510A and 510B are in a mirror image relationship, so there is no compatibility between the left and right side plate parts 510A and 510B, and it is necessary to separate the left and right side plate parts 510A and 510B. Management, parts management is very complicated
[0009] In addition, since the connecting arm 520 made of polyamide resin is horizontally placed on the curved inner peripheral side and the curved outer peripheral side of a pair of left and right side plate parts 510A, 510B formed of polyamide resin arranged apart from each other, a cross-sectional rectangular shape is formed. Therefore, the cable storage space cannot be sufficiently ensured at the time of assembly due to the strong bonding force of the side plate portions 510A, 510B or insufficient flexural rigidity or torsional rigidity of the side plate portions 510A, 510B and the connecting arm 520 Stable rectangular cross-sectional shape, and when storing and guiding various cables in the manufacturing fields of food and semiconductors in a clean environment, it is necessary to fully consider the sliding contact with the cable C or the mutual sliding of the side plate parts 510A and 510B. Dust such as abrasion powder caused by contact, etc., and excessive bending fatigue of joint 513

Abstract

A cable protection and guide device in which the number of parts used is reduced and assembly is simplified. Dust generation and bending fatigue is suppressed so that the cable protection and guide device exhibits excellent form stability of the cable accommodating space. Side plate portions and coupling portions are integrally molded from polyamide fatigue resistant resin into the form of a connecting link module. A polyacetal resin stopper link, which holds and limits the linear position and the bending position by engagement with the connecting link module, is inter-fitted with a coupling portion of the connecting link module by a snap-fit mechanism from the cable accommodating space side.

Description

technical field [0001] The present invention relates to a cable protection and guiding device. More specifically, it relates to accommodating cables such as cables or hoses for supplying energy such as electric power or compressed air to movable parts of industrial machinery, and relates to moving the movable parts. It is also possible to safely and reliably guide the cable protection guide device supporting the cables. Background technique [0002] As existing cable protection guides such as Figure 11 As shown, the following cable protection and guide device 500 is known. The cable protection and guide device 500 is configured such that a pair of left and right side plate parts 510A, 510B, which are arranged apart from each other, extend from the mounting fixed end to the mounting movable end, that is, in length A plurality of connected side plate parts 510A, 510B are connected in one direction, and the connecting arm 520 is spaced apart from each other, and a plurality of...
