DE3335483A1 - METHOD AND DEVICE FOR REMOVING THE EXTERNAL INSULATION OF SINGLE OR MULTI-WIRE CABLES - Google Patents

Description

The invention relates to a method and an apparatus for removing the outer insulation of single or multi-core cables.

To remove the insulation jacket, single-core or multi-core cables have been stripped with a tendon the one used for a round and longitudinal cut, the two opposite one another, such as the cable outside having rounded half-shells. The half-shells extend transversely to the jaws of the pliers, accordingly the length of the insulation to be cut, with protruding faces in the half-shell space and opposite cutting edges are located below a half-shell is opposite a stop plate another longitudinal cutting edge on the pliers arm, also attached to the length of the half-shells. Si | is used for making the longitudinal section in the iso lation.

The length of the insulation to be separated or cut out of the cable jacket is between see the half-shells clamped, the cutting edges penetrating the insulation and turning the pliers d Cut the insulation through a round cut. There-

after the separated part of the insulation between, the stop plate and the longitudinal knife clamped, the longitudinal knife executing the longitudinal cut. Man suggested that the insulation cut off in this way should also be removed with the pliers by removing the Place the outer edges of the half-shells on the longitudinal cut and pull them off in the clamped state.

In practice it has been shown that this operation cannot be carried out properly. The edges de Half-shells are too blunt to grasp and clamp the insulation between them. as required by the force required to pull it off. The result is that the pliers slip off the insulation.

The invention has set itself the task of eliminating this disadvantage of the prior art with a method and a stripping tool for performing the method with the aim of removing the stripping tool a corresponding design allows the cut insulation to be pulled off pral table without any problems in several process steps.

on the one hand have cutting edges 8, 9, 10, 11 protruding into the shell half-space. They lead in the stripping process of the cable 13 from the round section.

According to the invention is the longitudinal cutting edge required for making the longitudinal cut in the insulation 12 on one side of a half-shell, in the exemplary embodiment on the half-shell 6 on its outer side attached to the upper edge. This has the advantage that the longitudinal cutter 12, in addition to its cutting task, also can be used to pull off the insulation that has been cut off after the circular and longitudinal cut has been made can. This is done according to the following procedural steps: After making the longitudinal cut remains the cutting edge 12 in the kerf with the opposite half-shell 7 pressed against it, with through Turn the pliers to tear open the kerf and remove the cut insulating piece from its inner part Support released and finally pulled off completely when the shark shells 6, 7 approach, with their clamping effect will.

Another feature of the invention is that below the jaws 6, 7 arranged side cutter with the cutting edges 14, 15 therein. That when closed Pliers legs 1, 2 the cutting edges 14, 15 themselves
