Abstract: Power tools with housings or hammer cases include a thin wall titanium shell tapering from a smaller forward section to a larger rearward section; with at least the rearward section having a wall with a substantially constant wall thickness and an interface flange that includes an outer perimeter profile that is curvilinear and defines a plurality of outwardly extending detents that provide an interference fit with the wall of the hammer case.

Abstract: An electrical connector is provided that protects the electrical connector and associated components from harsh mechanical, electrical and environmental requirements. A jack is received by a jack housing, and a plug is received by a plug housing. The jack is adapted to receive the plug. A first seal member is positioned between the plug housing and the jack housing to form a seal therebetween when the jack and the plug are connected. A coupling member is attached to the plug housing and is adapted to receive the jack housing. A spring member is positioned between the coupling member and the plug housing to compress the first seal member between the jack housing and the plug housing.

Abstract: A wire connecting unit for an electrical connector for communication and data transmission systems includes a circuit board with a free and a near end and having four pairs of contacts mounted in a cantilever manner. The wire connecting unit has specific contact configurations that reduce crosstalk, attenuation, propagation delay, and other electrical and magnetic properties that interfere with communication and data transmission. In one embodiment, a first row of contacts extends generally upwardly and backwardly from the free end of the printed circuit board toward the near end, and a second row of contacts placed further from the free end of the printed circuit board than the first row of contacts extends generally upwardly and backwardly from the free end toward the near end.

Abstract: An electrical connector assembly includes a jack and a plug. The jack has a cavity for receiving the plug, a stop member and latch stop. The plug has a plug body and a resilient latch arm with an arm and an abutment. The latch stop is spaced from the stop member by a jack nominal dimension within a jack tolerance. The plug has a free end spaced from the arm abutment by a plug nominal dimension within a plug tolerance. The difference between the jack nominal dimension and the plug nominal dimension is not greater than the sum of the jack tolerance and the plug tolerance.

Abstract: A cover for a wall mounted enclosure having a faceplate with first and second sides and an aperture extending through the plate. A screw retention assembly is coupled to the plate adjacent the aperture by a flexible mechanism that is more flexible than the plate. The flexible mechanism is bendable with respect to three separate axes relative to the faceplate, allowing the screw retention assembly to float with respect to the plate about those axes. This enables the faceplate to fit flush against the wall and the screw retention assembly to fit flush against the enclosure even when the enclosure is misaligned or depressed relative to the wall.
