A charger includes a housing with an interface positioned in a front wall and configured to engage a battery pack. The interface includes charging terminals positioned between a first rail and a second rail, a first groove positioned between the first rail and a wall of the housing, and a second groove positioned between the second rail and the wall of the housing. The interface is in communication with an interior of the housing. A fan is coupled within the housing adjacent the interface, and an air passage member includes a hollow body that has a first end coupled to the fan and a second end spaced apart from the first end extending through another wall of the housing. The fan is operable to suck an air flow into the housing from outside the housing and guide the air flow through the air passage member to the interface.

Battery pack and charger system

A power tool including a housing that has a battery pack receiving portion configured to receive an interface of a battery pack, device contacts extending from the housing and configured to mechanically and electrically engage with the battery pack, and a latching mechanism supported by the housing and including an actuator and a latch member configured to selectively engage the interface of the battery pack. The actuator is pivotable to operatively pivot the latch member.

Locking mechanism for a battery pack on a portable electric device

A battery pack includes a housing, at least one battery cell, and a handle assembly. The battery cell is disposed within the housing. The handle assembly is coupled to the housing. The handle assembly includes a first handle catch, an elongate flexible member, a second handle catch, and a grip layer. The elongate flexible member has a first end and a second end. The elongate flexible member is coupled to the first handle catch. The first handle catch is disposed nearer to the first end than to the second end. The second handle catch is coupled to the elongate flexible member nearer to the second end than to the first end. The grip layer is disposed on at least a portion of each of the first handle catch, the elongate flexible member, and the second handle catch.

Charger and charger system

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.

Battery pack interface

A battery pack including a housing having a first portion and a second portion coupled to the first portion. The first portion has a first wall and an interface extends from the first wall. The interface includes a plurality of terminal apertures that provide access to electrical terminals within the housing. The second portion has a second wall, and the second wall is positioned opposite the first wall. A first plurality of vents extends through the first wall and a second plurality of vents extends through the second wall. A cumulative surface area of the first plurality of vents is different than a cumulative surface area of the second plurality of vents.

A battery charger includes a housing having support structure for simultaneously supporting at least two batteries of different types for charging including a first battery of a first type and a second batter of a second type. The battery charger further includes charger electronics supported by the housing and operable to output charging current to charge the first battery and charging current to charge the second battery. A fan is operable to cause air flow through the housing. A fan speed of the fan is adjustable based on a temperature of the battery charger (i) while at least one of the at least two batteries is coupled to the battery charger for charging and (ii) while no batteries are coupled to the battery charger for charging.

A hand-held band saw has a handle for grasping the band saw, a motor, a drive wheel driven by the motor, a driven wheel and a continuous blade disposed about the drive wheel and the driven wheel. A portion of the continuous blade is positioned in a cut zone to perform a cutting operation. A workpiece guard is spaced from the portion of the continuous blade and positioned between the portion of the continuous blade and the handle for limiting movement of the workpiece after the cutting operation.

Workpiece guard and blade guard for band saw

A hand-held band saw for cutting a workpiece. The hand-held band saw includes a deck, first and second wheels coupled to the deck for receiving a continuous blade thereabout, a motor coupled to the deck for driving at least one of the first or second wheels, and a handle providing a grip for a user to hold the band saw. The band saw also includes a blade guard having a first portion adjacent the first wheel, a second portion adjacent the second wheel, and a third portion adjoining the first and second portions. A joint couples the first, second, and third portions to the deck for simultaneous movement of the first, second, and third portions with respect to the deck.
