Abstract
A blade for cutting insulation from an insulated electrical conductor. The blade includes first and second opposed surfaces interconnected by an end. The end has an opening extending at a compound angle toward the interior of the blade. The opening is defined by a first pair of cutting edges converging at an angle less than 90.degree. toward the interior of the blade member and a second pair of cutting edges intersecting the first pair of cutting edges and converging toward the interior of the blade at a second non-parallel angle greater than the first angle. The blade is capable of maximizing the portion of the insulation that is cut from various size insulated conductors.
Claims11
An implement for cutting insulation from insulated electrical conductors, comprising:
- a blade member having first and second opposed surfaces and at least one end interconnecting the surfaces, said end having an opening extending at a compound angle toward the interior of the blade member, said opening being defined by a first pair of linear cutting edges extending from said end and converging at a first angle toward the interior of the blade member and a second pair of linear cutting edges intersecting the first pair of cutting edges and converging toward the interior of the blade at a second nonparallel angle greater than the first angle.
In an apparatus for cutting and stripping insulation from insulated electrical conductors,
- a pair of cooperating stripping blades mounted for reciprocal movement toward and away from each other, each blade having first and second opposed surfaces interconnected by an end, each end having an opening extending between the surfaces at a compound angle toward the interior of the blade, each opening being defined by a first pair linear of cutting edges intersecting the end and converging at a first angle toward the interior of the blade and a second pair of linear cutting edges intersecting the first pair of cutting edges and converging at a non-parallel second angle greater than the first angle toward the interior of the blade such that when the blades reciprocate toward each other, the cutting edges close over the insulated electrical conductor to cut the insulation and facilitate the stripping of the insulation.
An implement for cutting insulation about an insulator electrical conductor, comprising:
- a generally rectangular blade member having first and second faces and a first end interconnecting the faces, the first end having an opening extending between the faces at a compound angle toward an axis of the blade, the opening being defined by a first pair of cutting edges which intersect the first end and converge at a first angle less than 90.degree. toward said axis of the blade member and a second pair of cutting edges intersecting the first pair of cutting edges and converging to a vertex at a second non-parallel angle greater than the first angle and greater than 90.degree..
An implement for cutting insulation from insulated electrical conductors, comprising:
- a blade member having first and second opposed surfaces and at least one end interconnecting the surfaces, said end having an opening extending at a compound angle toward the interior of the blade member, said opening being defined by a first pair of cutting edges extending from said end and converging at a first angle toward the interior of the blade member and a second pair of cutting edges intersecting the first pair of cutting edges and converging to a vertex within the interior of the blade member, the second pair of cutting edges converging at a second nonparallel angle greater than the first angle.
