Abstract

Batteries having different form factors and power tools that are capable of using such batteries are described. In some embodiments, a power tool may use batteries having a post form factor as well as batteries having a slide form factor.

Claims

1. For use with a power tool have channels leading toward male, electrical connectors, a battery comprising:

one or more battery cells;

a housing comprising a base portion in which are housed the one or more battery cells and a connector portion that extends upward from an upper surface of the base portion; and

female, electrical connectors aligned with openings in the connector portion and electrically coupled to the one or more battery cells;

wherein the connector portion includes tabs that extend outwardly from opposite sides of the connector portion to form channels between the upper surface of the base portion and lower surfaces of the tabs such that the channels run along the opposite sides of the connector;

wherein the tabs are configured to slide along the channels of the power tool, align the male, electrical connectors with the female, electrical connectors, and cause the female, electrical connectors to receive the male, electrical connectors via the openings in the connector portion as the battery is slid into an engaged position in the power tool.

2. The battery of claim 1, wherein the opposite sides of the central portion each include a plurality of tabs that are spaced apart to form openings to receive corresponding tabs of the power tool.

3. The battery of claim 1, further comprising at least one detent to engage the power tool and secure the battery to the power tool when the battery is slid into the engaged position.

4. The battery of claim 3, further comprising at least one release button that disengages the at least on detent to permit disengaging the battery from the power tool.

5. The battery of claim 1, wherein the female, electrical connectors are female, electrical spade connectors that are configured to received male, electrical spade connectors of the power tool.

6. The battery of claim 1, wherein a rear portion of the housing extends above the connector portion.

15. The power tool of claim 7, battery of claim 1, wherein the channels include an opening at one end to permit receipt of corresponding tabs of the slide battery.

7. A power tool capable of using a post battery or a slide battery, the power tool comprising one or more battery powered components, and a battery compartment that includes:

a cavity to receive and guide a post portion of a post battery;

first electrical connectors positioned toward a distal end of the cavity and configured to electrically couple the post battery to the one or more battery powered components when the post battery is engaged with the power tool;

second electrical connectors positioned toward a proximal end of the cavity and configured to electrically couple a slide battery to the one or more battery powered components;

channels configured to slidably engage tabs of the slide battery and cause electrical connectors of the slide battery to electrical couple with the second electrical connectors as the slide battery is slid into an engaged position.

8. The power tool of claim 7, wherein the battery compartment further comprises tabs that extend inwardly from opposite sides of the battery compartment portion to form channels between a base surface of the battery compartment and an upper surface of the tabs such that the channels run along the opposite sides of the battery compartment.

9. The power tool of claim 8, wherein the opposite sides of the battery compartment each include a plurality of tabs that are spaced apart to form openings via which corresponding tabs of the slide battery are received.

10. The power tool of claim 7, further comprising at least one recess that receives a corresponding detent of the post battery and secures the post battery to the power tool when the post battery is in the engaged position.

11. The power tool of claim 7, further comprising at least one recess that receives a corresponding detent of the slide battery and secures the slide battery to the power tool when the slide battery is slid into the engaged position.

12. The power tool of claim 7, further comprising:

a power block that includes the second electrical connectors; and

a spring that exerts a force against the slide battery via the power block as the slide battery is slid into the engaged position.

13. The power tool of claim 12, further comprising:

at least one recess that receives a corresponding detent of the slide battery and secures the slide battery to the power tool when the slide battery is slid into the engaged position;

wherein the force exerted by the spring causes the slide battery to slide toward a disengaged position when the detent of the slide battery is released from the recess.

14. The power tool of claim 7, wherein the second connectors are male, electrical spade connectors that are configured to engage female, electrical spade connectors of the slide battery.
