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.
Claims15
An electrical combination comprising:
- an electrical device including a device housing providing a device support portion, and a circuit supported by the device housing;
- and
- 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 battery pack housing, power being transferrable between the battery cell and the circuit when the battery pack is connected to the device;
- one of the device support portion and the pack support portion including a body and a rail extending along an axis, the rail and the body defining a space therebetween, the space having a first dimension proximate a first axial location, a second dimension at a second axial location, and a third dimension at a third axial location, the first dimension, the second dimension, and the third dimension being different, and the other of the device support portion and the pack support portion including a first portion positionable in the space at the first axial location, a second portion positionable in the space at the second location, and a third portion positionable in the space at the third location,
- wherein the pack support portion includes the body and the rail defining the space therebetween, and wherein the device support portion includes an axially-extending device rail providing the first portion, the second portion, and the third portion, and
- wherein the device support portion includes a device body, the device rail and the device body defining a second space therebetween, the second space having a fourth dimension proximate the first portion, a fifth dimension proximate the second portion, and a sixth dimension proximate the third portion, the fourth dimension, the fifth dimension and the sixth dimension being different.
An electrical combination comprising:
- an electrical device including a device housing providing a device support portion, and a circuit supported by the device housing;
- and
- 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 device;
- one of the device support portion and the pack support portion including a body and a rail protruding from the body along an axis, the rail having a stepped rail surface extending along the axis, the stepped rail surface having a first rail surface portion proximate a first axial location, a second rail surface portion proximate a second axial location, and a third rail surface portion proximate a third axial location, and the other of the device support portion and the pack support portion including a first portion positionable proximate the first axial location, a second portion positionable proximate the second axial location, and a third portion positionable proximate the third axial location,
- wherein the rail and the body define a space therebetween, the space having a first dimension proximate the first axial location, a second dimension at the second axial location, and a third dimension at a third axial location, the first dimension, the second dimension, and the third dimension being different,
- wherein the first axial location is proximate an insertion opening at one axial end, the first dimension being larger than the second dimension and the third dimension, and
- wherein the third axial location is proximate an opposite axial end, the third dimension being smaller than the second dimension.
An electrical device comprising:
- a device housing providing a device support portion, and a circuit supported by the device housing;
- and
- the device support portion including a body and a rail extending along an axis, the rail and the body defining a space therebetween, the space having a first dimension proximate a first axial location, a second dimension proximate a second axial location, and a third dimension proximate a third axial location, the first dimension, the second dimension, and the third dimension being different,
- wherein the first axial location is proximate an insertion opening at one axial end, the first dimension being larger than the second dimension and the third dimension, and
- wherein the third axial location is proximate an opposite axial end, the third dimension being smaller than the second dimension.
