Abstract: An electric motor assembly includes a circuit board, a rotor assembly, and a stator assembly having a first end coupled to the circuit board and a second end opposite the first end. The stator assembly also includes an annular stator body having a plurality of inwardly projecting teeth. The stator assembly further includes windings wrapped about the stator body to form a plurality of coils. The stator assembly also includes a terminal coupled to an outer periphery of the stator body and extending longitudinally between the first end and the second end. The terminal is coupled to the circuit board at the first end and is coupled to the windings at the second end to electrically connect the windings to the circuit board. The terminal is molded to an attachment member, and the attachment member is molded to the outer periphery of the stator body.

Abstract: A power tool includes an elongated shaft forming a handle constructed of a non-conductive material and a tool head located at one end of the handle. The tool head includes a working element and a driven shaft configured to drive the working element. A powerhead located at an opposite end of the handle and includes an input shaft. A driveshaft extends between the tool head and the powerhead. The driveshaft is rotatably coupled to the input shaft and the driven shaft to transfer torque from the powerhead to the working element of the tool head. At least a portion of the driveshaft extending between the powerhead and the working element is constructed of a non-conductive material to inhibit transmission of electricity from the working element to the powerhead.

The tool head includes a working element and a driven shaft configured to drive the working element. A powerhead located at an opposite end of the handle and includes an input shaft. A driveshaft is coupled between the tool head and the powerhead. The driveshaft has a first driveshaft portion rotatably driven by the input shaft and a second driveshaft portion coupled to the first driveshaft portion and the driven shaft. The second driveshaft portion is driven by the first driveshaft portion to transfer torque from the powerhead to the working element. One of the first driveshaft portion or the second driveshaft portion is constructed of a non-conductive material or both of the first driveshaft portion and the second driveshaft portion are constructed of a non-conductive material.

Abstract: A telescoping tool includes a pole assembly, a driveshaft, a plurality of bearings, and at least one connection member. The pole assembly includes an outer pole and an inner pole. The inner pole is slidably received in the outer pole. The pole assembly is movable between a retracted configuration and an extended configuration. The driveshaft extends longitudinally in the outer pole and the inner pole. Each bearing of the plurality of bearings includes a driveshaft passage defined therein. The driveshaft passage receives the driveshaft therethrough. Each bearing further includes an end connection passage defined therein. The at least one connection member joins adjacent bearings of the plurality of bearings. The at least one connection member is disposed in the end connection passage of each of the adjacent bearings.

Abstract: A power tool includes a main housing having a pair of clamshells, each of which has a mating face and a blind bore within the mating face. The power tool further includes a motor having a front bearing retainer, a plurality of fasteners configured to secure the front bearing retainer within the main housing, and a pin received within the blind bores of the respective clamshells, such that each of the clamshells is inhibited from moving with respect to the other clamshell. The power tool further includes an output assembly having an anvil with an output member configured to engage a socket and a pawl that is moveable between a first position in which the pawl is operatively coupled to drive the anvil in a first direction and a second position in which the pawl is operatively coupled to drive the anvil in a second direction.

Abstract: A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.
