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.

Claims (26)

1. A punchdown tool comprising:

a housing including a front side, a back side, a front end, a rear end, an impact axis that extends through the housing, and an interior defined between the front and back sides;

a drive mechanism positioned in the interior of the housing adjacent the front end;

a circuit board positioned in the interior of the housing adjacent the rear end, the circuit board including a controller;

at least one battery electrically coupled to the circuit board, the at least one battery being at least partially positioned within the housing adjacent the circuit board and the rear end; and

a light positioned on the front end of the housing that is electrically coupled to the controller;

wherein a ratio is defined as a length of the punchdown tool in a direction parallel to the impact axis divided by a 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 max 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 160 millimeters to 170 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 , wherein the controller controls the light to blink when the at least one battery is low on power.

6. The punchdown tool of claim 1 , wherein the controller controls the light to stay on for a predetermined time period.

7. The punchdown tool of claim 6 , wherein the predetermined time period is fifteen minutes.

8. The punchdown tool of claim 1 , wherein the drive mechanism further includes a hammer, a drive spring, and an anvil with a barrel configured to receive an insert for impacting a wire.

9. A punchdown tool for fitting wires into connectors comprising:

a housing including 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;

a drive mechanism including a hammer, an anvil, and a drive spring, the drive mechanism positioned in the interior of the housing adjacent the front end;

a circuit board positioned in the interior of the housing adjacent the rear end, the circuit board including a controller;

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;

wherein the controller controls the light to stay on for a predetermined time period.

10. The punchdown tool of claim 9 , wherein the maximum diameter of the housing is within a range from 30 millimeters to 40 millimeters.

11. The punchdown tool of claim 10 , wherein a length defined between the front end and the rear end of the housing is within a range from 160 millimeters to 170 millimeters.

12. The punchdown tool of claim 9 , wherein the drive mechanism further includes a barrel that is configured to receive an insert for impacting a wire.

13. The punchdown tool of claim 9 , wherein the drive mechanism is movable between an unloaded position and a loaded position, and wherein the anvil is fully retracted in the housing when the punchdown tool is in in the loaded position.
