A battery for use in a power tool, including a battery housing, at least one battery cell in the battery housing, a pivoting member at least partially enclosed within the battery housing which moves between a latched position and an unlatched position, and a biasing device associated with the pivoting member for urging the pivoting member towards the latched position.

Battery for a power tool

Battery pack for a combustion tool

A battery contact module for use in a power tool including a housing () and a battery () insertable into the housing. The battery contact module () includes a contact block () movably connected to the housing () and a pair of opposing terminals () attached to the contact block () and configured to contact the battery (). Thus, the contact block () moves relative to the housing () to maintain constant electrical contact pressure between each of the terminals () and the battery (). The contact block () including locating posts () that loosely engage receptacle () on the housing () to allow for movement or float of the contact module in the housing.

Floating battery contact module for a power tool

A battery for use with, and electronically connected to a power tool having at least one electronic tool contact. The battery includes a battery housing, at least one battery cell disposed in the battery housing, and at least one terminal socket disposed within the battery housing, wherein each terminal socket includes at least one terminal for grippingly engaging an associated one of the at least one tool contact.

An adjustable depth of drive assembly for use with a fastener-driving tool includes a workpiece contact element having a contact end and an adjustment end, at least one stop configured for being secured to the tool and being normally moveable between an adjusting position in which the workpiece contact element is movable relative to the tool, and a locked position where the adjustment end is secured from movement relative to the tool, and at least one biasing element associated with the stop and configured for urging the stop and the adjustment end into a selected locked position relative to the tool without the use of tools.

Tool-free depth-of-drive adjustment for a fastener-driving tool

An adjustable depth of drive assembly for use with a fastener driving tool includes a workpiece contact element having a contact end and an adjustment end, a cage stop securable to the tool and being movable between an adjusting position in which the workpiece contact element is movable relative to the tool and a locked position wherein the adjustment end is secured to the tool, and a locking device associated with the cage stop and reciprocable between a locked position and an adjustment position for securing the cage stop and the adjustment end in a selected locked position relative to the tool without the use of tools. It is preferred that the adjustment end of the workpiece contact element has at least one toothed edge, and the cage stop has at least one toothed surface for engaging the at least one toothed edge in the locked position.

Tool-less depth adjustment for fastener-driving tool

An electrical connector comprises a plurality of electrical connector contacts which have insulation-displacement portions at first ends thereof and slidable pin-engaging portions at second opposite ends thereof whereby all wire-wrap electrical connections have been eliminated and all electrical connections between external wires and pin contacts of a second electrical connector are solderless. A gas tube over-protection printed circuit board can also be connected to the pin contacts of the second electrical connector in a solderless manner.
