Description

The invention relates to a cable support for attachment to a base body, with a rail, the rail having an inner surface that can be turned towards the base body, an opposite outer surface and a narrow surface, the inner surface and the outer surface being connected via the narrow surface, the rail having at least has four spaced folds, which divide the rail into five segments S1 - S5, the rail having an Ω-shaped section in a cross section Q1, the rail having a fastening means, which is a holding means that can be brought into a form fit with respect to an axis h Can be fixed to the base body, at least one fastening element being provided on at least one other of the inner segments S2 and/or S4, the inner surface of the outer segments S1 and S5 being able to be placed against the base body.

There is already a clip for routing a cable out of the WO 2012/129095 A1 known. This is a rail that is divided into three segments by means of two folds and whose cross-section forms a U-shape. The two outer segments have recesses through which the cable is routed. The cable runs over the middle segment.

In the EP 0 908 655 A2 describes a clamp for guiding a cable. The clip consists of a bar divided into five segments by means of folds and whose cross-section has an Ω-shape. It is fastened to a base body by a tightening strap that is guided through recesses in the rail, with the outer segments of the clamp resting against the base body. The tightening strap runs under the middle segment. A nut is welded onto the middle segment.

The invention is based on the object of designing and arranging a cable support in such a way that simplified assembly and savings in components are possible.

The object is achieved according to the invention in that the fastening element is designed as a web with a widening at the end on the narrow surface, which extends in a direction S at right angles to the axis h, so that a cable can be attached to the web on the outer surface using a cable tie, the cable tie has a positive fit normal and transverse to direction S with the rail.

The result of this is that the cable and the holding means do not impair one another due to their arrangement and the cable is therefore protected as much as possible. Furthermore, the cable support is in one piece and a separate holder is saved. The widening at the end leads to an undercut in relation to direction S, so that the cable tie cannot slip off the web in the direction of axis h.

It can also be advantageous for this if the fastening element is designed as an L-shaped web or T-shaped web.

Compared to round or funnel-shaped extensions, generally extensions with gradients, the L-shape minimizes the risk of the cable tie slipping. The T-shape, which can be formed from two L-shapes, holds the cable tie in two places and is therefore even more secure in terms of slipping.

Furthermore, it can be advantageous if two further segments S6, S7 or S6', S7' are formed or arranged by means of two further folds of the rail on at least one of the outer segments S1, S5 and if these segments S6, S7 or S6', S7' with the respective segment S1, S5 to which they connect, form an S-shaped section in the corresponding cross-section Q2 or Q2' and when a fastening means is attached to the outer segment S7 or S7'.

In this embodiment, the load-bearing function of the cable support is optimized, since two additional load-bearing segments counteract deformation of the clamp when there is an additional load.

It can also be advantageous if the fastening means has a nut fastened on the inner surface and the rail has a recess coaxial to the nut, so that a screw can be brought into positive locking with the nut from the outer surface. The nut can in particular be welded, clamped or pressed for attachment.

Furthermore, it can be advantageous if the rail is materially connected to the base body at the outer segments S1 and S5.

The attachment of the fastener to the inner surface of the rail is possible because the cable runs in direction S on the outer surface of the rail. Bolts, screws or other pin connections inserted from the outside of the rail into the fastener along axis h, even if they protrude beyond the fastener, do not interfere with the cable.

In this case, an arrangement consisting of a cable support as described above with a base body can advantageously be provided hen, the base body being a receptacle for insulating material, the receptacle being divided by two folds into a central base segment and two outer leg segments and having a U-shaped cross section Q3, with the cable support being directly connected to the base segment via segments S1 and S5 is in form or substance connection. A separate holder for the cable clamp on the base body is not necessary.

Advantageously, it is an assembly with an arrangement as described above with an insulating layer, the receiving trough being at least partially lined with the insulating layer on the side of the cable support, the cable being attachable to the side of the insulating layer opposite the receiving trough.

The arrangement of the insulating layer between the cable and the trough protects the cable from excessive heat on the part of the trough.

An assembly as described above with a housing wall is also advantageous, with the accommodating trough being screwed onto the housing wall and the insulation layer being held in the accommodating trough by means of a retaining strap.

Advantageously it is an assembly as previously described with a heat shield located on the outer surface of the cable support and secured to the nut by a bolt.

In addition, an exhaust system for a motor vehicle with an assembly as described above can be advantageous.
