CABLE RECEIVING DEVICE, CABLE TREE AND METHOD

The present invention relates to a cable receiving device for a cable harness, a wiring harness with such a cable receiving device and a method for producing such a cable receiving device.

For the electrical system of a motor vehicle or for cables in industrial plants Kings nen cable ducts, cable ducts and / or connecting elements, the example used to guide and / or support the cable can be used. The controlled guidance of the cables by means of such cable ducts, cable ducts and / or connecting elements facilitates the installation and installation of the cables. Such cable shafts, cable ducts and / or connecting elements are usually produced by means of a plastic injection molding process or by means of an extrusion process using thermoplastic raw materials. For safe and reliable operation of the on-board network, for controlling electronic components and for the operation of antennas, the requirements for electromagnetic compatibility must also be adhered to and precautions must be taken to ensure trouble-free operation. For this purpose, the cable harness can be traversed at susceptible areas with several magnetic components, such as rod-shaped or annular magnetic moldings. The production of such ferrite-based magneti shear shaped body is usually carried out by means of pressing of ferrite powder. The pressed moldings are then debindered, gesin tert and directed over an external magnetic field. Due to the fact that these magnetic elements are usually not connected directly to the cable ducts, cable ducts and / or connecting elements, an exact positioning of the magnetic elements is complicated.

Against this background, an object of the present invention is to provide an improved cable receiving device. Accordingly, a cable receiving device for a harness is pre-strike.

In the figures, the same or functionally identical elements have been given the same reference numerals, unless stated otherwise. 1 and 2 each show a schematic perspective view of an embodiment of a wiring harness 1. The wiring harness 1 comprises a cable strand 2. The wiring harness 2 extends in a longitudinal direction L. The cable strand 2 in turn comprises a plurality of cables 3, 4th of which in Figs. 1 and 2, only two are provided with a reference numeral. The cables 3, 4 can also be referred to as lines. The number of cables 3, 4 is arbitrary. The cables 3, 4 may have identical or different diameter and / or cross sections. The cables 3, 4 may be electrical cables, for example a phase cable, multi-phase cables, coaxial cables or the like. The Ka belbaum 1 may further optionally comprise a corrugated tube 5A or more corrugated tubes 5A, 5B, through which or through which the harness 2 is carried out. In particular, a first corrugated tube 5A and a second corrugated tube 5B are provided. Each corrugated tube 5A, 5B has alternately on ordered troughs and wave crests. The corrugated tube 5A extends in the longitudinal direction L. Also, the corrugated tube 5B may extend in the longitudinal direction L.

Furthermore, the wiring harness 1 comprises a cable receiving device 6. The Ka belbaum 1 and the cable receiving device 6 is preferably used in the field of automotive engineering application. The wiring harness 1 or the wire receiving device 6, however, can also be used in any other area, for example in watercraft, aircraft, rail vehicles or in building services. The corrugated tube 5A is at least partially received in the cable receiving device 6 relation ship as passed therethrough. However, the corrugated tube 5A is optional, as previously mentioned. Also, the corrugated tube 5B is optional.

For this end portions of the corrugated tubes 5A, 5B may be accommodated in the cable receiving device 6. The Kabelaufnahmevor device 6 may have engaging elements or engaging portions which are appro net, in the troughs of the corrugated hoses 5A, 5B intervene to the Ka Belaufnahmevorrichtung 6 positively with the corrugated tubes 5A, 5B bind to ver.

The cable receiving device 6 comprises a magnetic element 7. The magnetic element 7 is in particular a ferrite. Ferrites are electrically poor or non-conductive ferrimagnetic ceramic materials from the iron oxide hematite (Fe ₂ 0 ₃ ), more rarely from magnetite (Fe ₃ 0 ₄ ) or from other metal oxides. Ferromagnetism is a cooperative magnetic phenomenon that causes magnetization of ferromagnetic material. Such substances have a crystal structure in which within certain ranges (so-called

Districts), the magnetic moments of the atoms are alternately aligned in antiparallel. However, unlike the phenomenon of antiferromagnetism, they do not fully open each other because the orientation of the magnetic moments is stronger in either direction. Ferrimagnetism differs from ferromagnetism not in the arrangement of the Weiss districts, but in the magnetic order of the elementary magnets, which comes about through an energetically favorable orientation. The Magneti sations of two adjacent elementary magnets cancel each other partially, causing the Weiss districts are much weaker magnetized. The macroscopic behavior is thus a weaker form of ferromagnetism.

The magnetic element 7 may be divided into two and a first Magnetelementab section 8 and a second magnetic element section 9 include. The cable strand 2 or the corrugated tube 5A and / or the corrugated tube 5B are passed through the magnetic element 7 therethrough. The first Magnetelementab section 8 and the second magnetic element portion 9 each preferably have a semi-cylindrical geometry with a central recess. The Magne telement 7 itself is thus tubular. The central recess preferably has smooth walls.

In addition to the magnetic element 7, the cable receiving device 6 comprises a plastic molded part 10. The plastic molded part 10 is in particular an injection molded component. For example, the plastic molded part 10 may be made of polyamide (PA), polyethylene (PE), polypropylene (PP) or another suitable thermoplastic. The plastic molded part 10 comprises a first molded part section 11, in which the first magnetic element section 8 is received, and a second molded part section 12, in which the second magnetic element section 9 is taken. The first molded part section 11 and the second molded part section

12 are pivotally connected to each other by means of a hinge 13.

The hinge 13 can, as shown in FIGS. 1 and 2, as a thin-walled, the first mold part section 11 with the second mold part section 12 in one piece, in particular materialeinstückig, connecting web be formed. The hinge

13 is elastically deformable. In the present case, the term "integral material" is to be understood as meaning that the first molded part section 11, the second molded part section 12 and the hinge 13 form a one-piece component which is produced continuously from the same material. With the aid of the hinge 13, the plastic molded part 10 of an open state shown in Figs. 1 and 2, in which the cable harness 2 with the corrugated tube 5 A and / or the corrugated tube 5 B is inserted into the plastic molded part 10, in a closed, not shown Condition in which the plastic molded part 10 encloses the cable harness 2 or the corrugated tube 5 A and / or the corrugated tube 5 B, who spent the.

There are two such cable guide sections 14, 15, in particular a first cable guide portion 14 and a second cable guide section 15, provided between which the magnetic element 7 is positioned. The cable guide sections 14, 15 extend along the longitudinal direction L and can thus guide the cable strand 2 along the longitudinal direction L. The Ka belführungsabschnitte 14, 15 have the aforementioned engagement elements or engaging portions which are adapted to positively engage in the troughs of the corrugated tubes 5A, 5B. The engagement members or engagement portions may be rib-shaped. Each cable guide section 14 and 15 is in turn divided into two semi-cylindrical half-shells 16, 17 and 18, 19. The cable guide sections 14, 15 are thus tubular in the closed state of the plastic molded part 10. At the second cable guide section 15, a completely circumferential annular groove 20 (FIG. 2) can be seen easily. The cable guide sections 14, 15 and the Halbscha len 16, 18 each have snap hooks or latching hooks 21, of which in Figs. 1 and 2 only one is provided with a reference numeral.

The latching hooks 21 are adapted to engage positively in corresponding recesses 22 of the respective cable guide section 14, 15 or the half-shell 17, 19. In Figs. 1 and 2, only one recess 22 is provided with a reference numeral. A positive connection is formed by the meshing or engaging behind at least two Verbindpart partners, here the latching hooks 21 and the recesses 22. With the help of Rastha ken 21 and the recesses 22 thus the first mold part section 11 and the second mold part section 12 may be positively connected to each other ,

The plastic molded part 10 further comprises a receiving portion 23 for receiving the magnetic element 7. The receiving portion 23 is like the cable guide sections 14, 15 each divided into two half-shells 24, 25. In this case, the receiving portion 23 between the two cable guide portions 14,

In particular special in each case the half-shells 16, 18, 25 and the half-shells 17, 19, 24 in one piece, in particular materialeinstückig, connected to each other. The Aufnah meabschnitt 23 is thus tubular in the closed state of the plastic molded part 10.

The receiving portion 23 preferably comprises a plurality of snap hooks or latching hooks 26, of which in FIG. 1 only one with a reference mark is provided chen. For example, the two half-shells 24, 25 associated with each two such latching hooks 26. With the help of the latching hooks 26, the magnetic element sections 8, 9 can be positively fastened in the receiving portion 23 be. That is, for producing the cable receiving device 6, the magnetic element 7 is pressed in the form of the two magnetic element sections 8, 9 in the two half-shells 24, 25 of the receiving portion 23, wherein the Rastha ken 26 are resiliently deformed and the magnetic element sections 8, 9 positively engage behind or embrace , With the help of the receiving portion 23 is thus always a defined position of the magnetic element 7 in or on the wiring harness 1 guaranteed. The magnetic element 7 can thus be used selectively for absorption from the electromagnetic radiation.

Alternatively, the magnetic element 7 can also be materially connected to the Aufnahmeab section 23. In this case, the magnetic element sections 8, 9 may be glued, for example, in the receiving portion 23. Furthermore, the magnetic element 7 or the magnetic element sections 8, 9 can also be molded or back-injected in a plastic injection molding process with material of the plastic mold part 10. Furthermore, the Ka belaufnahmevorrichtung 6 can also be made using a multi-component injection molding process ago. In this case, in an injection molding tool used for producing the plastic molding 10 ther moplast and a composition, in particular a so-called compound comprising a thermoplastic and a ferrite powder, in particular a hard ferrite powder, for the preparation of the magnetic element 7 use. The magnetic element 7 can then be magnetized in the injection mold, as long as the Ther moplast is not solidified and the ferrite powder can be aligned in a magnetic field out.

In such a multi-component injection molding process, the mold filling of a cavity forming the magnetic element 7 and then a cavity molding the plastic molded part 10 takes place in the closed injection molding tool first. The plastic molding 10 may thus integrally with the Magnetic element 7 are formed. The cable receiving device 6 thus has after demolding from the injection mold a defined portion for absorbing electromagnetic radiation, namely the magnetic element 7, and another portion, namely the plastic molded part 10, consists only of the thermoplastic used for the production of the plastic molding 10.

FIGS. 3 and 4 each show a schematic perspective view of another embodiment of a wiring harness 1. The embodiment of the Ka belbaums according to FIGS. 3 and 4 differs from the embodiment of the wiring harness 1 according to FIGS. 1 and 2 only in that In addition to the particular special first plastic molded part 10, a second plastic molded part 27 is vorgese hen.

The second plastic molded part 27 is in particular a so-called Y-distributor. With the help of the second plastic molded part 27 of the cable harness 2 example, on several corrugated tubes 5A, 5B are divided. The second plastic molded part 27 comprises a first half-shell 28 and a second half-shell 29 which are pivotally connected to each other by means of a hinge 30. At the second half-shell 29 a plurality of snap hooks or latching hooks 31 is provided which are adapted to intervene in corresponding recesses 32 of the first half-shell 28 in a form-fitting manner. Furthermore, the plastic molded part 27 comprises a provided on the two half-shells 28, 29 provided annular engagement portion 33 which is adapted to engage positively in the provided on the second cable guide portion 15 annular groove 20. As a result, the second plastic molded part 27 and the first plastic molded part 10 can be positively connected with each other.

That is, in this case, the plastic molding 10 is formed in two parts.

Between the first mold part section 11 and the second mold part section 12, a magnetic element 7 is introduced in the form of a closed annular body. The wire harness 2 is passed through the first mold part section 11, the magnetic member 7 and the second mold part section 12. The first mold part section 11 comprises a cable guide portion 14 in the form of a spring which is resiliently deformable and prevents kinking of the cable strand 2 at a turn of the same. The cable guide section 14 guides the cable harness 2 along its longitudinal direction L.

The second molded part section 12 comprises a plurality of snap hooks or latching hooks 21, which are adapted to lock into corresponding recesses 22 of the first molded part section 11.
