Abstract: A portable electronic device having a stationary housing enclosing a first electric circuit and a pivotable housing enclosing a second electric circuit, uses a mechanical and electrical interconnection assembly for interconnecting the two housings and circuits. The mechanical assembly includes a pivot and friction assembly that pivotally couples the stationary and pivotal housings together, and allows the pivotable housing to be held at a variety of angular orientations with respect to the stationary housing. The electrical assembly includes an electrical connector of a flexible web type that pivotally and electrically connects the first and second electric circuits together. Rather than pivoting at the pivot point or axis, the electrical connector pivots about or along a relatively great distance compared to the pivot axis, thereby greatly reducing the possibility of the electrical conductor breaking at the pivot.

Abstract: A cable connector having a lower profile improves connection of cables to junction boxes where there are space limitations near the box. The connector is of a simpler design than the existing art and therefore can be economically mass produced and easily assembled in an automated manufacturing line.

Abstract: To reliably maintain an EMI grounding connection between a sheet metal computer chassis wall and a computer cover wall that may be removably placed against the outer side of the chassis wall, a lance structure is formed in the chassis wall, and opposing installation notches are formed in the chassis wall on opposite sides of the lance opening. Transversely enlarged end portions of an elongated arcuate sheet metal grounding strip are inserted inwardly through the wall notches and captively retained within the lance structure with a longitudinally intermediate portion of the arcuate strip body extending outwardly through the chassis wall lance opening. When the cover wall is operatively installed on the chassis wall the grounding strip is resiliently flattened and compressed between the lance strip and the installed cover wall to maintain an EMI grounding path between the contiguous chassis and cover walls.

Abstract: Weatherproof electrical enclosure apparatus includes an electrical outlet and a cover pivotally secured to the outlet for sealingly engaging outlet elements to prevent moisture and foreign material from contacting electrical elements of the outlet.

Abstract: A specially designed metal grounding cap is placed over a metal-plated housing boss upon which a printed circuit board is to be mounted by extending a screw through a hole in the circuit board and tightening the screw into a metal insert previously forced into the free end of the mounting boss. As the screw is tightened into the boss insert, an EMI grounding pad on the underside of the circuit board engages an end wall of the grounding cap and pushes it into forcible engagement with the inner end of the boss. The forcible engagement of the grounding cap end wall causes leg portions of the cap to pivot inwardly and engage portions of the plated boss side wall between the boss insert and the metal plated housing wall from which the boss inwardly projects.
