Strain relief for quick assembly for a cable carrier

An energy chain comprising end fastening plates forming an end of the energy chain and comprising a strain relief for a plurality of lines, wherein the strain relief is arranged adjacent to the end fastening plates and the retaining frame being held in position together with the end fastening plates and at a terminal end thereof, the strain relief comprising:

• a first rail and an opposing second rail, which are connected by side parts, wherein the first and the second rail and the side parts form in a closed position a retaining frame in an assembly plane;
• at least two block-type spacers, which are retained in the retaining frame and between which a plurality of lines, such as cables or hoses, is feedable through in a feedthrough direction, the feedthrough direction and assembly plane being substantially transverse to each other;
• the retaining frame in the closed position exerting clamping force on the block-type spacers via the side parts and/or the rails to provide strain relief of lines to be fed through;
• wherein a first end region of each of the side parts is mounted swivelably on the second rail and a second end region cooperates in each case with the first rail for releasable fastening, such that each side part is swivelable from the closed position into an open position, in which the block-type spacers are released for insertion or removal of lines,
• wherein each side part has a swivel opening at the first end region, by which it is retained releasably on a respective swivel pin at an end of the second rail and is mounted swivelably thereon, wherein the swivel opening and the swivel pin define a swivel axis parallel to the feedthrough direction.

An end fastening for an energy chain, comprising two end fastening plates and comprising a strain relief, wherein the strain relief comprises:

• a first rail and an opposing second rail, which are connected by side parts, wherein the first and the second rail and the side parts form in a closed position a retaining frame in an assembly plane;
• a plurality comprising more than two block-type spacers, which are retained in the retaining frame and between which a plurality of lines, such as cables or hoses, is feedable through in a feedthrough direction, the feedthrough direction and assembly plane being substantially transverse to each other;
• the retaining frame in the closed position exerting clamping force on the block-type spacers via the side parts to provide strain relief of lines to be fed through;
• wherein a first end region of each of the side parts is mounted swivelably on the second rail and a second end region cooperates in each case with the first rail for releasable fastening, such that each side part is swivelable from the closed position into an open position, in which the block-type spacers are released for insertion or removal of lines;
• wherein each side part has a swivel opening at the first end region, by which it is retained releasably on a respective swivel pin at an end of the second rail and is mounted swivelably thereon, wherein the swivel opening and the swivel pin define a swivel axis parallel to the feedthrough direction;
• wherein the block-type spacers are embodied as elongate clamping parts with opposing clamping surfaces and arranged in the retaining frame with their clamping opposing surfaces transverse to the rails;
• wherein in the closed position the side parts are arranged to bring about a clamping force perpendicular to the feedthrough direction and parallel to the rails;
• and
• wherein the strain relief is bolted together with the end fastening plates by fastening holes, in the side parts, in a direction perpendicular to the assembly plane and/or has a clamping jaw or a retaining clip on each side part, for form-locking engagement in the end fastening plates in the closed position.
