Abstract
An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.
Claims20
An ejector for an electrical combination, the electrical combination including a battery pack and an electrical device, the ejector comprising:
- an ejection member engageable between the battery pack and the electrical device;
- a biasing member operable to bias the ejection member toward an ejecting position in which a force is applied to disengage the battery pack and the electrical device;
- and
- a switch operable with the ejection member, the switch deactivating at least a portion of the electrical device as the ejection member moves toward the ejecting position.
An electrical combination comprising:
- an electrical device including a device housing providing a device support portion, and a circuit supported by the device housing;
- a battery pack including a battery pack housing providing a pack support portion for engagement with the device support portion, a battery cell supported by the housing, power being transferrable between the battery cell and the circuit when the battery pack is connected to the electrical device;
- and
- an ejector including:
- an ejection member engageable between the battery pack and the electrical device,
- a biasing member operable to bias the ejection member toward an ejecting position, in which a force is applied to disengage the battery pack and the electrical device, and
- a switch operable with the ejection member, the switch deactivating at least a portion of the electrical device as the ejection member moves toward the ejecting position.
An electrical combination comprising:
- an electrical device including a device housing providing a battery-receiving portion having a plurality of battery contacts and an end wall, and a circuit supported by the device housing;
- a battery pack receivable in the battery-receiving portion, the battery pack having a battery pack housing and a battery cell supported by the housing, the battery cells coupled to battery contacts supported by the battery pack housing;
- and
- an ejector including
- an ejection member engageable between the battery pack and the electrical device,
- a biasing member operable to bias the ejection member toward an ejecting position in which a force is applied to disengage the battery pack and the electrical device, and
- a switch operable with the ejection member, the switch deactivating at least a portion of the electrical device as the ejection member moves toward the ejecting position.
