Abstract: An enclosure includes a base unit and a cover unit that snaps into the base unit easily, but is difficult to remove from the base unit without knowledge of the appropriate disassembly technique. The appropriate disassembly technique includes the application of pressure at key regions of the base assembly. The application of pressure at the key regions distorts the base assembly so as to disengage key portions of the cover unit from the base unit. The cover unit includes protrusions having an inclined surface and a flat surface. The inclined surface facilitates manufacturing assembly, and the flat surface encumbers the disassembly of the enclosure. The application of pressure at the key regions distorts the base unit so that the flat surfaces of the protrusions on the cover unit are disengaged from the base unit. In a preferred embodiment, the base unit is a resilient insulating material, such as plastic, and the cover unit is a shielding and heat sinking material, such as sheet metal.

Abstract: An electrical connecting device is provided which includes a housing comprising at least one orifice having disposed therein a connector for making electrical connection between electrical power-providing components and electrical power-receiving components. The connector includes inner and outer flange structures which substantially envelop edge portions of the orifice to provide a substantially continuous seal between at least side and bottom edge portions of the orifice and connector. In especially preferred embodiments, the edge portions of the orifice are contained in a groove formed between the inner and outer flange structures.

Abstract: An electrical connector for use in completing at least one electrical circuit is provided which includes a first half-connector body having an inner and outer flange structure which upon insertion into a housing comprising an orifice is effective to substantially envelop edge portions of the orifice to provide a substantially continuous seal between at least side and bottom edge portions of the orifice and connector. The first half-connector body also includes at least one opening for making electrical connection between electrical power-providing components and electrical power-receiving components. In especially preferred embodiments, the inner and outer flange structure define a substantially continuous groove about the periphery of the side and bottom edge portions and the connector includes an upper wall portion having a groove for containing a complementary tongue portion.

Abstract: A generally rectangular, flat, conductive metal sheet is formed and provided with a predetermined array of apertures and slots by stamping. The sheet is generally comprised of first and second lateral sections and upper and lower center sections which are each coupled to a respective lateral section by a thin jumper, or bridge, element or elements. Each section further includes a mounting/terminal pin extending from a respective lower edge thereof. The sheet is then bent such as by automatic handling apparatus along three spaced axes located between or extending through the various sections and along and parallel to the length of the sheet from top to bottom so as to form a generally "E"-shaped structure when viewed from above. Four axial lead diodes are then inserted within respective pairs of facing slots within the lateral and center sections and are soldered in place.

Abstract: An elongated printed circuit (PC) board connector having a plurality of terminal pins aligned in a linear array has attached to its terminal pins an elongated, linear, U-shaped bus bar with a plurality of apertures in its lower edge. A plurality of U-shaped conductors are inserted through respective pairs of edge apertures in the bus bar, with the distal ends of each of the conductors adapted for coupling to a terminal on a PC board upon which the connector is mounted by means of a pair of support columns and nut/bolt combinations. The bus bar, terminal pins and conductor combination is then dip soldered to establish mechanical coupling and electrical connection therebetween.

Abstract: A two piece heat sink includes a first elongated mount/support member adapted at a first end for secure mounting on a printed circuit (PC) board and a second finned convector member adapted for secure, intimate coupling to a second end of the first mount/support member. The second convector member has a serrated aperture, or channel, therein and a plurality of fins disposed about its lateral periphery and aligned along the longitudinal axis of the first mount/support member so as to be oriented generally perpendicular to the plane of the PC board. The mount/support member is tapered along its length and its second end is beveled to facilitate its insertion within the second member's aperture to permit the mount/support member to be press fit coupled to the convector member.

Abstract: A heat sink positioned on a printed circuit (PC) board includes a generally planar center portion and first and second pluralities of spaced planar ribs extending generally transversely from respective lateral edges of the center portion. The heat sink is adapted for generally perpendicular mounting on the PC board and includes first, second and third mounting tabs respectively extending from the lower edges of the bottom lateral ribs of the first and second pluralities of lateral ribs as well as from the lower edge of the planar center portion. Each mounting tab is adapted for insertion within a respective aperture in the PC board and includes an elongated proximal portion and a distal end portion.
