Abstract
The present disclosure relates to a new improved dual crimping and cutting tool, such as a portable hand tool with removable for repair or adding features having a rotating jaw serving in one area as a cutter blade against the body of the tool, and in an adjacent area a crimping portion for conducting a semi-circular crimping for one of multiple size conductors. The invention includes features such as a multi-die removable wheel, a rounded periphery multi-die removable wheel, a dual segment jaw, a multiple angle crimping nest, a new jaw with a self-release and a manual release, a high leveraged multi-groove driving pawl, and a removable blade system.
Claims22
A hand tool for crimping and cutting a conductor, the hand tool comprising:
- a body;
- a jaw connected pivotally to the body via a pivot comprising an external pulling edge and an internal edge comprising at least a cutting portion and a crimping portion;
- a first handle connected or part of the body;
- a second handle pivotally connected to the body for creating a force upon the external pulling edge by relative movement of the second handle around the pivot;
- a cutter connected or part of the body for cutting a connector when the jaw is pivoted by the force applied upon the external pulling edge as the connector is compressed between the cutter and the cutting portion;
- and
- a crimping wheel with a plurality of nests each for a different connector size connected to the body for crimping the connector and a lug when the jaw is pivoted by the force applied upon the external pulling edge for mating the crimping portion and the crimping wheel a first of the nests.
A crimping wheel for a crimping tool, the wheel being made of metal and having a general thickness and an outer periphery along an external circular radius, the wheel also including at least a plurality of U-shaped nests carved in the external circular radius each sized for a connector size for receiving and crimping a connector and a lug placed and forced against a set of walls of one of the U-shaped nest.
A jaw fora crimping and cutting hand tool, the jaw having a thickness and comprising a curved L-shaped body in the thickness with a pivot connector on one end of the L-shaped body for rotation around the pivot connector, an external pulling edge portion on the outer side of the L-shaped body, and at least a crimping portion and a cutting portion on an internal edge portion of the L-shaped body.
A method of mechanically and conductively crimping a conductor using a hand tool comprising a body, a jaw connected via a pivot pivotally to the body comprising an external pulling edge and an internal edge comprising at least a crimping portion and wherein the crimping portion includes a V-shaped portion, the tool including a first handle connected or part of the body, a second handle pivotally connected to the body, and a crimping wheel with a plurality of nests, the method comprising the steps of:
- selecting a conductor for crimping;
- selecting a lug sized for the conductor for crimping;
- opening the jaw by clockwise pivot of the jaw around the pivot;
- selecting one of the plurality of nests in the crimping wheel adapted for crimping of the conductor and the lug selected;
- inserting between the selected nest and the V-shaped portion of the jaw the conductor and the lug;
- and
- moving the first handle by relative movement of the second handle around the pivot to create a force upon the external pulling edge rotating counter-clockwise the jaw;
- repeating the movement of the previous step of the second handle until the V-shaped portion touches the crimping wheel.
The method of claim 21, wherein the previous two steps include the creation of a five point crimping force upon the conductor and the lug wherein two of the five points are on the V-shaped portion and three of the five points are inside the nest selected on the wheel.
