Perforation apparatus for cable jackets and related systems and methods
A perforation apparatus for use with cable jackets and related systems and methods thereof is provided. The tool includes a pliers assembly having at least a first jaw member positioned opposing a second jaw member, wherein relative movement of the first and second jaw members is controlled with at least a first handle and a second handle. A first knife edge is on the first jaw member and a second knife edge is on the second jaw member. Each of the first and second knife edges are oriented substantially parallel to one another and substantially perpendicular to a length of first and second handles. The first and second knife edges are movable towards one another. A spacing device is connected to the pliers assembly, wherein the spacing device controls a closing distance between the first knife edge and the second knife edge.
1. A perforation apparatus comprising:
a pliers assembly having at least a first jaw member positioned opposing a second jaw member, wherein relative movement of the first and second jaw members is controlled with at least a first handle and a second handle, wherein the first and second handles are approximately the same length and adapted to be moved together by a hand of a user, and wherein the moving together of the handles moves the first and second jaw members toward one another;
a first jaw tip disposed at a distal end of the first jaw member, and a second jaw tip disposed at a distal end of the second jaw member, wherein at least one of the first jaw tip and the second jaw tip is of a cylinder geometry having end faces consisting of two arcs each arc having a first end point and a second end point, wherein the first end points of each arc are connected to each other and the second end points of each arc are connected to each other, forming a biconvex geometry;
a first knife edge disposed on the first jaw tip, and a second knife edge disposed on the second jaw tip, each of the first and second knife edges oriented substantially parallel to one another, wherein each of the first and second knife edges is oriented substantially perpendicular to a length of first and second handles, wherein the first and second knife edges are movable towards one another; and
a spacing device connected to the pliers assembly, wherein the spacing device controls a closing distance between the first knife edge and the second knife edge.
2. The perforation apparatus of claim 1 , wherein the spacing device is adjustable to vary the closing distance between the first knife edge and the second knife edge.
3. The perforation apparatus of claim 1 , wherein the closing distance is a predetermined distance determined by a configuration of the spacing device.
4. The perforation apparatus of claim 1 , wherein the spacing device further comprises a threaded tensioner.
5. The perforation apparatus of claim 1 , wherein the cylinder geometry is that of a right cylinder.
6. The perforation apparatus of claim 1 , wherein at least one of the first and second jaw tips is oriented angularly with respect to the length of the first and second handles.
7. The perforation apparatus of claim 1 , wherein the first and second jaw tips each have a width dimension that is larger than a width dimension of the first and second jaw members, respectively.
