A collection of components for a cable tray system provide the components and basic hardware for assembling and installing a cable tray that can change direction in three dimensions to avoid obstacles or other cables' trays while negotiating a designated space. Components of the cable tray system may be modular, that is, pre-configured for ease of assembly, such as vertical kits and horizontal bend kits, while others are supplied in lengths for cutting them to fit jobsite requirements, such as rails and rungs. Both components provide an inherent framework that facilitates conceptualization and construction of a cable tray system at the jobsite with flexibility and simplicity to allow the present cable tray system to be employed more efficiently and accurately.

A rail system, in particular for assembling or fastening seats in an aircraft, includes an assembly rail, in particular a seat rail for assembling or fastening a seat, a first panel, in particular a first floor panel for arrangement next to and substantially in parallel with the assembly rail, at least one cover element which is movable for covering the assembly rail, and a levelling device for levelling the upper surface of the first panel, in particular for levelling a recess or depression in said panel when the at least one cover element covers the assembly rail.

Each spaced apart support for a cable run in a preferred form includes a hook having a relatively narrower width along the direction of the cable run. A respective extender attached above each hook has a greater length along the cable run than the width of the support in the direction of the cable run, and the extenders thereby provide extended support for cable resting on the extenders along the cable run. Each extender has a slight downward curvature. The opposite ends of each extender have a sharp downward curvature so that the extenders will support resting cable passing over the supports and avoid damage to the cable passing off the extender. A plurality of the supports may be spaced apart at a greater interval such that the longitudinal ends of adjacent extenders are spaced apart defining an acceptable length gap over which the cable run passes.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.

Process assemblies and cable management assemblies for managing cables in tight envelopes. A processing assembly includes a top chamber having at least one substrate support, a support shaft, a robot spindle assembly, a stator and a a cable management system. The cable management system includes an inner trough assembly and an outer trough assembly configured to move relative to one another, and a plurality of chain links configured to house at least one cable for delivering power to the process assembly.

A protector is equipped with a first bent portion protecting part protecting a horizontally-bent first bent part of a wire group; a second bent portion protecting part protecting a downwardly-bending second bent part; a first cover part; a second cover part; and a first locking part, the first cover part being integrally linked to the first bent portion protecting part and being closed and locked, and the second cover part being integrally formed with, and developed on the same plane as, the first cover part and being bent downwardly and closed and locked after the first cover part is closed, and the second cover part being equipped with a second locking part.

An integral, unitary cover assembly for covering an electrical connection between first and second electrical cables each having a primary conductor and a neutral conductor, includes an elastomeric inner sleeve, an elastomeric outer sleeve surrounding the inner sleeve, and a collapsible duct assembly interposed radially between the inner and outer sleeves. The inner sleeve defines a cable passage to receive the electrical connection and the primary conductors of the first and second cables. The duct assembly includes an outer duct sleeve member defining a first passage and an inner retention member disposed in the first passage. The retention member defines a second passage configured to receive at least one of the neutral conductors therethrough. The duct sleeve member is flexible. The retention member maintains the duct sleeve member in an open configuration when the retention member is disposed in the first passage. The duct sleeve member is selectively collapsible about the at least one neutral conductor from the open configuration to a collapsed configuration by withdrawing the retention member from the first passage.

A high-voltage line for motor-vehicle high voltage includes an interior tube surrounding an interior cavity of the high-voltage line, an electrically conducting interior conductor surrounding the interior tube, an intermediate insulation surrounding the interior conductor, an electrically conducting outer conductor surrounding the intermediate insulation, and an outer insulation surrounding the outer conductor. The outer insulation, the outer conductor, the intermediate insulation, the interior conductor, and the interior tube are disposed coaxial to one another.

A cable tray assembly includes first and second cable tray sections each including a base and rails extending transversely from longitudinal sides of the base. At least one of the base and the rails defines a plurality of holes. A splice plate is configured to engage the first and second cable tray sections for attaching the first cable tray section to the second cable tray section. The splice plate defines a plurality of holes. At least one snap-fit connector includes a head and a plurality of resiliently deflectable arms extending from the head. The arms of the connector are configured to extend through aligned holes in the splice plate and one of the cable tray sections to secure the splice plate to said one of the cable tray sections.

A cable routing structure includes a plurality of cables that are superposed on one another and that are movable relatively to one another in length directions thereof, and a line length difference housing case that contains parts of the plurality of cables and is movable in a reciprocating direction. The line length difference housing case absorbs differences in line length among the plurality of cables generated in accordance with a moving position of the line length difference housing case.
