Abstract

The invention provides an electrical combination including a power tool having a housing supporting a motor, which is operable to drive a tool element. The electrical combination also includes a battery and an adapter supportable on the housing of the power tool and electrically connectable to the power tool and the battery such that the adapter transfers electrical power between the battery and the motor. The adapter has a locking arrangement engageable with the battery for preventing the adapter from being removed from the power tool housing while the battery is connected to the adapter.

Claims (32)

1. An electrical combination comprising:

a power tool having a housing supporting a motor, the motor being operable to drive a tool element;

a battery; and

an adapter supportable on the housing of the power tool and electrically connectable to the power tool and the battery such that the adapter transfers electrical power between the battery and the motor, the adapter having a locking arrangement engageable with the battery for preventing the adapter from being removed from the power tool housing while the battery is connected to the adapter.

2. The electrical combination of claim 1 , wherein, when the battery is electrically connected to the adapter, the adapter at least partially encloses the battery.

3. The electrical combination of claim 1 , wherein the locking arrangement includes a locking member and an actuator operable to move the locking member between a locked position and an unlocked position, and wherein, when the battery is electrically connected to the adapter, the battery prevents the locking member from being moved toward the unlocked position.

4. The electrical combination of claim 3 , wherein the battery includes a latching arrangement including a locking member and an actuator operable to move the locking member between a locked position and an unlocked position, and wherein, when the battery is secured to the adapter, the actuator of the battery is adjacent to the actuator of the adapter.

5. The electrical combination of claim 1 , wherein the locking arrangement includes a locking member engageable with the housing of the power tool and an actuator operable to move the locking member into engagement with the power tool, and wherein, when the battery is electrically connected to the adapter, the battery prevents the locking member from being moved out of engagement with the housing of the power tool.

6. The electrical combination of claim 1 , wherein the adapter extends across a side surface of the battery.

7. The electrical combination of claim 1 , wherein the power tool has a first connecting configuration and the battery has a second connecting configuration, the second connecting configuration being different than the first connecting configuration.

8. The electrical combination of claim 7 , wherein the adapter has a first connecting configuration engageable with the first connecting configuration of the power tool and a second connecting configuration engageable with the second connecting configuration of the battery to connect the battery to the power tool.

9. The electrical combination of claim 8 , wherein the locking arrangement secures the first connecting configuration of the adapter to the first connecting configuration of the power tool, and wherein the battery prevents the locking arrangement from being removed from the first connecting configuration of the power tool.

10. An electrical combination comprising:

an electrical component including a component housing, and an electrical circuit supported by the component housing;

a battery; and

an adapter having a locking arrangement and being electrically connectable to the power tool and the battery such that the adapter transfers electrical power between the battery and the electric circuit of the power tool, the locking mechanism being movable between a locked position, in which the locking mechanism secures the adapter to the power tool, and an unlocked position, in which the adapter is removable from the power tool, the locking mechanism being maintained in the locked position when the battery is connected to the adapter.

11. The electrical combination of claim 10 , wherein, when the battery is electrically connected to the adapter, the adapter at least partially encloses a first side and a second side of the battery.

12. The electrical combination of claim 10 , wherein the locking arrangement includes a locking member and an actuator operable to move the locking member between the locked position and the unlocked position, and wherein, when the battery is electrically connected to the adapter, the battery prevents the locking member from being moved between the unlocked position and the locked position.

13. The electrical combination of claim 12 , wherein the battery includes a latching arrangement including a locking member and an actuator operable to move the locking member between a locked position and an unlocked position, and wherein, when the battery is secured to the adapter, the actuator of the battery is adjacent to the actuator of the adapter.

14. The electrical combination of claim 10 , wherein the locking arrangement includes a locking member engageable with the housing of the power tool and an actuator operable to move the locking member into locking engagement with the power tool, and wherein, when the battery is electrically connected to the adapter, the battery prevents the locking member from being moved between the unlocked position and the locked position.

15. The electrical combination of claim 10 , wherein the adapter extends around the battery.

16. The electrical combination of claim 10 , wherein the power tool has a first connecting configuration and the battery has a second connecting configuration, the second connecting configuration being different than the first connecting configuration.

17. The electrical combination of claim 16 , wherein the adapter has a first connecting configuration engageable with the first connecting configuration of the power tool and a second connecting configuration engageable with the second connecting configuration of the battery to connect the battery to the power tool.

18. The electrical combination of claim 17 , wherein the locking arrangement secures the first connecting configuration of the adapter to the first connecting configuration of the power tool, and wherein the battery prevents the locking arrangement from being removed from the first connecting configuration of the power tool.

19. The electrical combination of claim 10 , wherein the electrical component is a power tool, and wherein the electric circuit includes a motor supported in the housing, the motor being operable to drive a tool element.

20. A method of operating an electrical combination, the electrical combination including a power tool having a housing supporting a motor, a battery, and an adapter having a locking arrangement, the method comprising the acts of:

connecting the battery to the adapter and connecting the adapter to the power tool;

transferring electrical power from the battery to the electric circuit of the power tool;

operating the motor to drive a tool element; and

moving the locking arrangement relative to the adapter between a locked position, in which the locking arrangement secures the adapter to the housing of the power tool, and an locked position, in which the adapter is removable from the housing of the power tool, the battery preventing movement of the locking arrangement toward the unlocked position, when the battery is secured to the adapter.

21. The method of claim 20 , further comprising removing the battery from the adapter and charging the battery in a battery charger.

22. The method of claim 20 , further comprising removing the battery from the adapter before removing the adapter from the housing of the power tool.
