Abstract
A tension relief for supply lines and a block-like clamping part therefor, which has a lateral surface designed as a clamping surface. The clamping surface of the clamping part is formed at least in one clamping portion by an elastic wall, which is delimited on the side facing away from the clamping surface by a cavity structure, which is formed by additional walls. The clamping part can be variedly used without modification on certain line diameters, in particular in a tension relief of a cable carrier or also in a connector housing.
Claims28
A strain reliever for supply lines of a supply line device, comprising:
- a clamping apparatus having at least one block-like clamping part which has a side surface configured as a clamping surface for clamping the supply lines in place in a clamping direction against a further clamping surface of the clamping apparatus, the strain reliever being designed for passage of the supply lines in a longitudinal direction perpendicular or approximately perpendicular to the clamping direction, wherein the clamping surface is formed, at least in a clamping portion intended for clamping the supply lines in place, by an elastic wall, wherein, on a side facing away from the clamping surface, the elastic wall bounds a cavity structure which extends through the clamping part in or approximately in the longitudinal direction, wherein a number of passage openings of the cavity structure adjoin one another via further inner elastic walls, wherein the clamping part has a transverse bracing, which extends over a main dimension and which is connected in one piece to a lattice-like arrangement, and wherein the lattice-like arrangement comprises walls arranged in pairs, wherein the walls in each pair have an interposed passage opening which has a cross-sectional shape which tapers to a point away from the elastic wall and the walls in each pair merge at an end region remote from the clamping surface in one piece into the transverse bracing.
An energy chain having the strain reliever as claimed in 1.
A clamping part for the strain reliever, comprising:
- the clamping part being produced in one piece from an elastic plastics material and having two opposing side surfaces each of which comprises a clamping surface for clamping at least one supply line in place in a clamping direction against a further clamping surface, for strain relief of the at least one supply line in a longitudinal direction perpendicular or approximately perpendicular to the clamping surface, wherein at least one side surface, preferably both side surfaces in each case has/have, at least in a region of the clamping surface intended for clamping the supply lines in place, a first elastic wall which bounds a cavity structure on a side facing away from the clamping surface, which structure is formed by a lattice-like arrangement of a number of further elastic walls which are connected in one piece to the first elastic wall, wherein the cavity structure has a number of passage openings which adjoin one another via the further elastic walls, wherein the clamping part has a transverse bracing, which extends over a main dimension and which is connected in one piece to the lattice-like arrangement, and wherein the lattice-like arrangement comprises walls arranged in pairs, wherein the walls in each pair have an interposed passage opening which has a cross-sectional shape which tapers to a point away from the elastic wall and the walls in each pair merge at an end region remote from the clamping surface in one piece into the transverse bracing.
A clamping part for a strain reliever, comprising:
- the clamping part being produced in one piece from an elastic plastics material and having two opposing side surfaces each of which comprises a clamping surface for clamping at least one supply line in place in a clamping direction against a further clamping surface, for strain relief of the at least one supply line in a longitudinal direction perpendicular or approximately perpendicular to the clamping surface, wherein at least one side surface, preferably both side surfaces in each case has/have, at least in a region of the clamping surface intended for clamping the supply lines in place, a first elastic wall which bounds a cavity structure on a side facing away from the clamping surface, which structure is formed by a lattice-like arrangement of a number of further elastic walls which are connected in one piece to the first elastic wall, wherein the cavity structure has a number of passage openings which adjoin one another via the further elastic walls, wherein, on two opposing narrow sides of the clamping part, which are positioned perpendicular to the side surfaces, in each case at least one projection and/or one indentation is provided for form-fitting retention in a frame, wherein the projection and/or the indentation extends in the clamping direction or transversely of the longitudinal direction.
