Abstract
The present disclosure provides a mini or micro hand-held, portable, battery-powered 2-3 ton crimp tool capable of crimping conductors ranging between #22 AWG and #2 AWG to a termination. The crimp tool has a C-shaped head portion that uses linear motion to perform the crimp operation.
Claims20
A hand-held, battery-powered in-line crimp tool comprising:
- a frame having a working head portion and a handle portion, the working head portion having a C-shaped structure, and the handle portion including a drive system that translates rotational movement of an electric motor to linear movement of a ram extending at least partially onto the working head portion, the drive system including:
- the electric motor adapted to be powered by a battery;
- a gear reduction assembly used to reduce the output speed of a shaft of the electric motor by a predetermined factor;
- a ram drive system having a drive arm operatively coupled to the gear reduction assembly, and a drive surface operatively coupled to the drive arm such that rotation of the drive arm causes linear movement of the drive surface;
- and
- a linkage assembly operatively associated with the drive surface, such that when the shaft of the electric motor rotates in one direction the drive surface causes the linkage assembly to move from a retracted position to an extended position and when the shaft of the electric motor rotates in an opposite direction of the one direction the drive surface causes the linkage assembly to move from the extended position to the retracted position.

- a frame having a working head portion and a handle portion, the working head portion having a C-shaped structure, and the handle portion including a drive system that translates rotational movement of an electric motor to linear movement of a ram extending at least partially onto the working head portion, the drive system including:
- the electric motor adapted to be powered by a battery;
- a gear reduction assembly used to reduce the output speed of a shaft of the electric motor by a predetermined factor;
- a ram drive system having a drive arm operatively coupled to the gear reduction assembly, a wedge support having a bore that receives at least a portion of the drive arm such that rotation of the drive arm causes linear movement of the wedge support, and a wedge having a drive surface;
- and
- a linkage assembly comprising:
- a first link pair with each link in the link pair having first and second mounting holes;
- a second link pair with each link in the link pair having third and fourth mounting holes;
- and
- a roller having a center bore positioned between the first and second link pairs;
- wherein the second link pair is coupled to the first link pair by positioning a pivot pin within the second mounting holes of the first link pair and the third mounting holes of the second link pair, and wherein the roller is positioned between the first and second link pairs by positioning the pivot pin through the center bore of the roller;
- and
- wherein the roller is aligned with the drive surface of the wedge such that linear motion of the wedge support causes the linkage assembly to move between a retracted position and an extended position.
