Description

The The invention relates to a stripping tool for cables, in particular for cables with an inner conductor and at least one coaxial one Outer conductor.

at Such a stripping tool becomes a cutting blade around the cable guided around until it penetrated to a predetermined depth is to the outer sheath or the dielectric between inner and outer conductor to cut. When cutting through the outer Mantels, it is particularly important that the outsider, which usually consists of a thin mesh or foil, not damaged. To at an axially remote location then continue to penetrate to the inner conductor is, first of all to cut the outer conductor. In the next step the dielectric between the outer and inner conductor is severed, taking care now that the inner conductor is not damaged.

coaxial There are many different embodiments with one Outer diameter from 2 to 15 mm. Special shapes can have an outer diameter of 1 to 100 mm.

to Group of coaxial cables also include the so-called miniature coaxial cable (Mini coax) where the stripping process due to the very small Dimensions and other special features of these cables especially difficult. Especially in mobile use it is for the user difficult with hand tools such mini-coax cable stripping properly. For the Outer conductor is common in mini-coax cables a steel or steel-copper braid or foil is used. The inner conductor is usually a copper strand of several, very thin Individual wires. Also for the dielectric between Inner and outer conductors become different materials, such as polytetrafluoroethylene (PTFE) or else lacquered glass silk used, whereby also the material strength varies from cable to cable, depending on the to the cable made demands.

Many different tools for stripping coaxial cables are known in the prior art. From the DE 86 09 173 U1 For example, a stripper for coaxial cable is known in which an interchangeable tool unit is provided, which is used depending on the type of cable. As a cutting tool is a knife, which is variable via an adjusting screw in its depth of cut. The stripping device described here brings simultaneously several circumferential cuts with the desired different depth of cut in the cable.

From the CH 502 706 is a stripper for staged stripping of coaxial cables known. Depending on the type of cable, a different number of blades are arranged in parallel, the distance and cutting depth of which can be set individually. For different cable types, prepared different blade carriers can be used. By a motor device, the coaxial cable is unrolled by the displacement of a carriage in the longitudinal direction of the blades on the blades and cut in this way on the circumference.

From the DE 35 34 299 A1 a device for settling a Koaxialkabelendes is known, which comprises a substantially cylindrical housing in which a paring knife for peeling the outer insulation, a separating knife for cutting the outer conductor and the dielectric and an end stop are provided. The housing is screwed onto the end of the coaxial cable until it stops, which means that the paring knife is already removing the outer insulation. Now, if the cable or the housing is rotated in the opposite direction, the cutting blade is brought into a lowered position, wherein the outer conductor and the dielectric are severed simultaneously. A differentiated settling of outer conductor and dielectric is not provided here.
