Abstract

An insulation stripping assembly for stripping insulation from a conductor. The blade assembly includes a first blade assembly and a second blade assembly. The first blade assembly has a first cutting blade, and the second blade assembly has a second cutting blade. A clenching member is provided on at least one of the first blade assembly and the second blade assembly. The clenching member is spaced from the first cutting blade and the second cutting blade. The first and second cutting blade essentially cut through the insulation and the clenching member engages the insulation to provide increased pulling force to remove the cut insulation from the conductor.

First claim

The invention claimed is:

1. An insulation stripping assembly for stripping an insulation slug from a conductor, the insulation stripping assembly comprising:
a first blade assembly, the first blade assembly having a first cutting blade;
a second blade assembly, the second blade assembly having a second cutting blade;
a first clenching member positioned on the first blade assembly, the first clenching member extending into an insulation receiving slot a distance less than the first cutting blade, a second clenching member positioned on the second blade assembly, the second clenching member extending into the insulation receiving slot a distance less than the second cutting blade, the first clenching member being spaced from the first cutting blade and the second clenching member being spaced from the second cutting blade, the first and second clenching members are blades positioned to cooperate with the insulation slug;
support surfaces are provided proximate the first cutting blade and the first clenching member and proximate the second cutting blade and the second clenching member, the support surfaces define the insulation receiving slot;
wherein the first and second cutting blade essentially cut through the insulation and the first and second clenching members pierce an outer layer of the insulation slug, wherein as the insulation stripping assembly is moved toward the insulation slug, the first blade assembly, the second blade assembly, the first clenching member and the second clenching member engage the insulation slug to provide increased pulling force to remove the insulation slug from the conductor.

2. The insulation stripping assembly as recited in claim 1 , wherein the first blade assembly is fixed.

3. The insulation stripping assembly as recited in claim 1 , wherein the second blade assembly is movable.

4. The insulation stripping assembly as recited in claim 1 , wherein a plurality of first and second clenching members are provided.

5. A insulation stripping assembly for stripping an insulation slug from a conductor, the blade assembly comprising:
a first blade assembly, the first blade assembly having a first cutting blade and a first clenching member, the first clenching member being spaced from the first cutting blade, the first clenching member cooperates with the insulation slug to be removed from the conductor, the first clenching member having first inclined surfaces to form a first clenching blade;
a second blade assembly, the second blade assembly having a second cutting blade and a second clenching member, the second clenching member being spaced from the first cutting blade, the second clenching member cooperates with the insulation slug to be removed from the conductor, the second clenching member having second inclined surfaces to form a second clenching blade;
an insulation receiving slot for positioning insulation of the conductor therein;
support surfaces are provided proximate the first cutting blade and the first clenching member and proximate the second cutting blade and the second clenching member, the support surfaces define the insulation receiving slot;
the first clenching member extending into the insulation receiving slot a distance less than the first cutting blade, the first clenching member positioned to pierce outer insulation of the insulation slug, the second clenching member extending into the insulation receiving slot a distance less than the second cutting blade, the second clenching member positioned to pierce the outer insulation of the insulation slug at a position opposite the first clenching member;
wherein the first and second cutting blades essentially cut through the insulation and the first and second clenching members pierce the outer insulation of the insulation slug, wherein as the insulation stripping assembly is moved toward the insulation slug, the first and second clenching members pierce the outer insulation of the insulation slug to provide increased pulling force to remove the insulation slug from the conductor.

6. The insulation stripping assembly as recited in claim 5 , wherein a plurality of first and second clenching members are provided.

7. The insulation stripping assembly as recited in claim 5 , wherein the first blade assembly is fixed.

8. The insulation stripping assembly as recited in claim 5 , wherein the second blade assembly is movable.

9. A insulation stripping assembly for stripping an insulation slug from a conductor, the insulation stripping assembly comprising:
a first blade assembly, the first blade assembly having a first cutting blade and a first clenching blade which cooperates with the insulation slug to be removed from the conductor, the first clenching blade being spaced from the first cutting blade;
a second blade assembly, the second blade assembly having a second cutting blade and a second clenching blade which cooperates with the insulation slug to be removed from the conductor, the second clenching blade being spaced from the first cutting blade;
an insulation receiving slot for positioning insulation of the conductor therein;
support surfaces are provided proximate the first cutting blade and the first clenching blade and proximate the second cutting blade and the second clenching blade, the support surfaces define the insulation receiving slot;
the first clenching blade extending into the insulation receiving slot a distance less than the first cutting blade, the first clenching member positioned to pierce outer insulation of the insulation slug, the second clenching blade extending into the insulation receiving slot a distance less than the second cutting blade, the second clenching blade positioned to pierce the outer insulation of the insulation slug at a position opposite the first clenching blade;
wherein the first and second cutting blades essentially cut through the insulation and the first and second clenching blades pierce the outer insulation of the insulation slug, wherein as the insulation stripping assembly is moved toward the insulation slug, the first and second clenching blades pierce the outer insulation of the insulation slug to provide increased pulling force to remove the insulation slug from the conductor.

10. The insulation stripping assembly as recited in claim 9 , wherein a plurality of first clenching blades are provided on the first blade assembly and a plurality of second clenching blades are provided on the second blade assembly.
