Electric cable protector in cable pipeline

Abstract

A retainer device for conductors in an electrical raceway, which is applicable mainly to raceways formed by the association of a U-shaped base section (2) with a cover section, in which the base section (2) is provided in the walls thereof with equal equidistant narrow transverse slots which define therebetween outstanding transverse tabs or strips which form a comb-like arrangement. The device is formed by an open narrow annular member (1) of right prismatic profile, the bottom portion whereof corresponds to the right internal cross section of the base section (2), of the raceway to which it is directed. The member (1) has a bottom portion (1A), two wall portions (1B) and two free end portions (1C, 1D), where the two free end portions (1C, 1D) are located at the level of the open side of the base section, are facing each other in overhanging fashion and are partly overlapping, at the same time as the two wall portions (1B) are provided with projections for interacting with the walls and / or with the wall portion (1B) of an adjacent member.

Description

technical field [0001] The present invention relates to a wire retainer device in a cable duct, in particular to a retainer device capable of retaining wires in a bundle, the wires being accommodated in a cable duct defined by a defined side wall and Formed by a U-shaped base portion of a bottom wall and a flat top cover portion connected to the U-shaped base portion, the base portion being provided in the wall of the duct with equally spaced transverse grooves defining fins therebetween , the fins collectively form a comb configuration. The invention also relates to how to use a retainer according to the invention. Background technique [0002] Devices are known for retaining a bundle of electrical wires in a cable duct having imperforate walls. This retainer is only connected to the bottom wall of the duct and has means for accommodating longitudinal distribution members, such as those disclosed in Spanish Utility Model No. 196,298, wherein the retainer means are enclose...

AI Technical Summary

Problems solved by technology

[0003] The purpose of these existing retainer devices is to prevent the wires from falling out of the cable duct when the retainer top cover is removed from the cable duct to handle the wires. These retainer devices have such Or the disadvantage of that: when a new wire is to be inserted into the wire harness, the new wire must be screwed through the retainer device when the retainer device is of the closed type; where the retainer device is open, the Channels reduce the reliability of device retention; and in all cases, these devices are only connected to the bottom wall of the cable duct, whereby their strength cannot be obtained because they do not bond the cable duct walls together.
