Abstract

A hand-held tool that includes a housing. The housing includes a handle. A tool also includes a motor assembly, a battery assembly and a circuit board. The motor assembly includes a motor, the motor including a rotatable motor output shaft, a motor positive terminal and a motor negative terminal. The motor assembly also includes a first rigid conductive electrical connector having a first end fixed to the motor positive terminal and a second end fixed to the circuit board. The battery assembly includes a battery cell with a battery cell positive terminal and a battery cell negative terminal. The battery assembly further includes a second rigid conductive electrical connector having a first end fixed to the battery cell positive terminal and a second end fixed to the circuit board.

First claim

What is claimed is:

1. A hand-held tool, comprising:
a housing, the housing including a handle;
a motor assembly including a motor;
a first battery assembly;
a circuit board; and
a actuator configured to selectively turn on the motor;
wherein the first battery assembly comprises a first battery cell with a first battery cell positive terminal and a first battery cell negative terminal;
wherein the first battery assembly further comprises a first rigid conductive electrical connector having a first end fixed to the first battery cell positive terminal and a second end fixed to the circuit board and a second rigid conductive electrical connector having a first end fixed to the first battery cell negative terminal and a second end fixed to the circuit board.

2. The hand-held tool of claim 1 , wherein the first battery cell comprises a longitudinal axis which is disposed at an angle with respect to the circuit board, the angle being between 10 degrees and 90 degrees.

3. The hand-held tool of claim 1 , wherein at least one of the first rigid conductive electrical connector and the second rigid conductive electrical connector runs parallel to a longitudinal axis of the first battery cell.

4. The hand-held tool of claim 1 , wherein the first rigid conductive electrical connector and the second rigid conductive electrical connector are a stamped metal connectors.

5. The hand-held tool of claim 1 , wherein the first rigid conductive electrical connector is soldered to the circuit board; and
wherein the second rigid conductive electrical connector is soldered to the circuit board.

6. The hand-held tool of claim 1 , wherein the first rigid conductive electrical connector is fixed to the circuit board by a tulip connector; and
wherein the second rigid conductive electrical connector is fixed to the circuit board by a tulip connector.

7. The hand-held tool of claim 1 , wherein the hand-held tool comprises a hand-held vacuum cleaner.

8. The hand-held tool of claim 1 , wherein the hand-held tool comprises a power tool configured to hold and drive a bit.

9. The hand-held tool of claim 1 , further comprising a second battery assembly comprising a second battery cell.

10. The hand-held tool of claim 9 , wherein the second battery assembly further comprises a second battery cell positive terminal and a second battery cell negative terminal.

11. The hand-held tool of claim 10 , wherein the second battery assembly further comprises a third rigid conductive electrical connector having a first end fixed to the second battery cell positive terminal and a second end fixed to the circuit board and a fourth rigid conductive electrical connector having a first end fixed to the second battery cell negative terminal and a second end fixed to the circuit board.

12. The hand-held tool of claim 9 , wherein the motor has a longitudinal axis and the first battery cell is disposed parallel to the longitudinal axis of the motor.

13. The hand-held tool of claim 9 , wherein the second battery cell is disposed parallel to a longitudinal axis of the motor.

14. The hand-held tool of claim 9 , wherein the motor comprises a rotatable motor output shaft; and
wherein the motor is connected to the circuit board by motor rigid conductive electrical connectors.

15. The hand-held tool of claim 1 , wherein the first battery cell is adjacent to the motor.

16. The hand-held tool of claim 9 , wherein the first battery cell is disposed on a first side of the motor; and
wherein the second battery cell is disposed on a second side of the motor opposite the first side of the motor.

17. The hand-held tool of claim 1 , wherein the first battery cell is configured to be charged by a battery charger that includes a primary cell monitor.

18. The hand-held tool of claim 17 , wherein the first battery cell is configured to be charged by a battery charger that includes a secondary cell monitor.

19. The hand-held tool of claim 17 , wherein the first battery cell is configured to be charged by a battery charger that includes an independent charge shut-off.
