Abstract

A punchdown tool for fitting wires into connectors including a housing with a front side, a back side, a front end, a rear end opposite the front end, a leading surface on the front end, and an interior defined between the front and back sides. The punchdown tool also includes a drive mechanism with a hammer, an anvil, and a drive spring. The drive mechanism is positioned in the interior of the housing adjacent the front end. The punchdown tool further includes a circuit board positioned in the interior of the housing adjacent the rear end with a controller. The punchdown tool also includes a light positioned on the leading surface of the housing that is electrically coupled to the controller and at least one battery positioned in the interior of the housing for supplying power to the light and the circuit board.

First claim

What is claimed is:

1 . A punchdown tool comprising:
a housing that defines an impact axis that extends through the housing in a longitudinal direction, the housing including a front end and a rear end opposite the front end; a drive mechanism positioned in the housing, the drive mechanism movable between an unloaded position and a loaded position, the drive mechanism including a hammer movable along the impact axis; and an anvil movable along the impact axis, the anvil including a barrel; wherein, when the drive mechanism is in the loaded position, the barrel of the anvil does not extend beyond the front end of the housing, wherein a ratio is defined as a total length of the punchdown tool in a direction parallel to the impact axis divided by a total length of the drive mechanism in a direction parallel to the impact axis, and wherein the ratio is in a range from 1.5 to 2.0.

2 . The punchdown tool of claim 1 , wherein the housing defines a maximum diameter of the punchdown tool that is within a range from 30 millimeters to 40 millimeters.

3 . The punchdown tool of claim 2 , wherein a length defined between the front end and the rear end of the housing is within a range from 150 millimeters to 180 millimeters.

4 . The punchdown tool of claim 2 , wherein the rear end of the housing includes a lobe that defines the maximum diameter of the housing.

5 . The punchdown tool of claim 1 , the housing comprising an interior between the front end and the rear end, the punchdown tool comprising a light positioned on a leading surface of the housing.

6 . The punchdown tool of claim 5 , the punchdown tool comprising a circuit board positioned in the interior of the housing, the circuit board including a controller electrically coupled to the light.

7 . The punchdown tool of claim 5 , comprising a battery positioned in the interior of the housing for supplying power to the light.

8 . The punchdown tool of claim 1 , comprising an insert coupled to the barrel, wherein, when the drive mechanism is in the loaded position, the insert partially extends into the housing.
