Problems solved by technology

Hitherto shielding foils had to be removed from such round cables with laborious work
Manual removal process is cumbersome, costly and inefficient
In addition, there is a risk that the insulation protection at the end of the cable may be damaged

Embodiment Construction

[0036] figure 1 The cable end of the shielded four-core round cable 10 is shown. The four cores of the shielded round cable 10 are denoted by 11, wherein each core has a conductor 16 and an insulating portion 15 covering the conductor. The conductor 16 is generally a core wire or wire made of a conductive metal material such as copper or aluminum. The cable ends 11 are bundled in a circular shape and are twisted around a filler 17 made of insulating material that is circular in cross section. The filler 17 may also be composed of textile fibers. Additionally, the round cable 10 may have a metal wire in the center. The round cable 10 is externally protected by a sheathed insulating part 18 constructed of PVC or other electrically insulating elastic synthetic materials to prevent weather or other external influences. In order to achieve electrical shielding, the round cable 10 has a shielding metal wire 19 made of conductive material and a shielding film 20. The shielding fil...

Abstract

The invention provides a cable processing apparatus for removing a shield film (20) from a shielded four-core round cable (10). The cable processing apparatus has four cutting tools capable of moving radially toward a round cable (2, 3, 4, 5) for cutting a mask film (20). Here, the cutter (2, 3, 4, 5) is distributed to the core (11) of the circular cable (10). The cutting edges (23, 24, 25, 26) of the cutters (2, 3, 4, 5) are respectively recessed. The cutter (2, 3, 4, 5) is provided with guiding elements (6, 7, 8, 9); the guiding element has guide segments (27, 28); the core (11) wrapped by the shielding film is accommodated in the boot segment. The knives (2, 3, 4, 5) protrude with respect to the guide elements (6, 7, 8, 9) in the area of the guide segments (27, 28) with the amount of interference (t). The guide segments (27, 28) have a cylindrical recessed shape and form a recessed abutment against the core (11).

Description

Technical field [0001] The invention relates to a cable processing device and a method for removing a shielding film from a shielded multi-core round cable Background technique [0002] Multi-core round cables are composed of wire cores bundled in a round shape and usually twisted. The wire core is composed of a conductor (for example, a core wire or a wire made of a conductive material such as copper or aluminum) and an insulating part surrounding the conductor. The shielded multi-core round cables are widely used in automobiles or other motor vehicles as signal cables, for example. The signal cables are electromagnetically shielded from each other very well in order to ensure high data transmission quality, so that the electromagnetic waves emitted by the cables will not cause undesired interference in the on-board electronic devices of the vehicle, for example. In order to shield the round cable, the core is surrounded by a shielded metal wire made of metal conductive materi...
