Cable clamp

The invention relates to a ScheXle for fastening cables, pipes and similar line elements.

There are already numerous such clamps known which are in one piece and are attached to the anchoring material by a bolt, nail, screw or the like. E.g. a clamp is described in German patent specification 1 048 307, which has a foot part which is attached to the anchoring material and serves to support the conduit element. An essentially band-shaped tab is hinged to this foot part, which at its outer end has a nose provided pin. To fasten the line element, it is placed on the foot part and the tab over the

Line element folded up to the nose of your pin engages in an opening provided for this purpose on the foot part. Depending on the diameter of the line element, this is the case use matching clamps of different lengths.

The invention has set itself the task of a clamp create that can be used for line elements of different cross-section, in addition to the required mechanical Load-bearing capacity as quick and simple and thus cost-saving assembly as possible was taken into account » de.

According to the invention, this is done in the case of one-piece clamps in The type in question is achieved in that the bolt and / or bolt seated in the outer end region of the strip-shaped tab the recess provided on the foot part for receiving this peg are designed so that the peg is in the recess against automatic loosening at any penetration depth, i.e. is also secured under the forces acting on the strip-shaped tab in the operating state.

A tough, weaker one is used as the material for the clamp Cross-sections, however, a material that is easily flexible, e.g. plastic such as polyolefins, polyamide and the like.

The lower part has a right-angled to the base ... arranged hole, which in a countersink for receiving the fastening nut or the head of a screw flows out. The cross-section of the hole is either round or oblong, which makes the clamp different Kinds can be attached to the wall. The hole has a circular cross-section and the inner diameter is slightly smaller than the outer diameter of the If the bolt is inserted or hammered in, it is held exclusively by the surrounding pressure the widened hole.

This type of fastening can be improved by a A roughened surface of the bolt in any form, e.g. edge grooving, thread, annular grooves and the like will.

The elongated shape of the hole has the advantage that the clamp can be adjusted transversely to the wiring harness when arranged in a row. It is then fastened in Usually with nails or screws, which is why the countersink is made correspondingly deep for this purpose is and avoided that the head of the nail or the screw in the holding area of the cable or pipe protrudes.

Instead of a nut, a movable one can also be used as the fastening element Slider made of solid plastic may be provided.

The one-piece design of the clamp in plastic and the closing of the band around the pipe or cable without accessories ^ The use of metallic connecting elements gives the clamp a preferred application in areas where there is a risk of corrosion Environment and, on the other hand, no time-consuming fastening manipulation of the cable,

The innovation is shown in the accompanying drawing based on exemplary embodiments,

Fig. 1 shows the open cable clamp in the view and partly in section with a hole for plugging on on a threaded bolt.

Fig. 2 shows a cable clamp with a slightly different shape compared to Fig. 1.

Fig. 3 shows, in partial section, those on a base attached cable clamp in closed position.

Fig. 4 illustrates the cable clamp according to Fig. 3, however tab

Fig. 5 shows the cable clamp in section V - V in Fig. 4

After inserting the cable or pipe 1 in the on his Base 2 attached lower part 3 of the cable clamp the laterally, tangentially to the rounding 4, hinged, band-shaped flap 5 folded over and the retaining pin 6 located at its end into the one provided on the lower part 3 Inclined retaining hole 7 knocked in until the tab 5 firmly encloses the cable or tube 5. Of the Retaining pin 6 is provided with annular beads that snap into adapted annular grooves in the retaining bore 7 of the lower part. The retaining pin 6 can also have a pointed thread or a buttress thread 9 or the like be provided with the appropriate counter-shape for good locking of the retaining pin. But it can also with the appropriate Material selection only have the retaining pin 6 annular beads or threads, while the wall 10 of the retaining hole is smooth.

The fastening of the cable clamp to the base 2 after Fig. 1 takes place by press fit of the bolt 11 in the passage. Hole 12, the through hole 12 opens into the recess 13, which is dimensioned so that a screw nut 14 finds space in it. To correct misalignments, the cable clamp according to FIG. 2 is provided with a parallel to the elongated hole 15 slidable slider 16 equipped with a central through thread 17. Two opposite guide rails 18 prevent the sliding piece 16 from falling out of the lower part 3

Attachment of the cable clamp by means of a corresponding one on the foot trained setting tool are attached to the side of the lower part 3 adjustment strips 19 »

The possibility of variable driving depth of the Holding pin 6 in the holding hole 7 can, within narrow limits, cables or pipes 1 of different diameters be attached.
