A housing for protectively enclosing a printed circuit board, including a base, and a pair of parallel spaced vertical housing side walls extending upwardly from the base to define a chamber that receives the central portion of the printed circuit board, whereby the vertical edge portions of the board extend outwardly beyond the corresponding vertical edges of the housing side walls, respectively. Vertical side members having generally U-shaped horizontal cross-sectional configurations are mounted on the outwardly extending edge portions of the printed circuit board, respectively, with the leg portions of each side member extending between the housing side walls and the printed circuit board, respectively, whereby portions of housing side walls overlap the side member leg portions. The upper end of the chamber is closed by a lid member that is fastened between the upper ends of the side members.

A compressible sealing gasket for supporting a cable in a wall opening contained in a housing wall includes a pair of gasket sections each having a planar surface that contains a recess, and at least one integral compressible sealing projection extending from the planar surface adjacent the recess. When the gasket sections are placed in an assembled condition with their planar surfaces in contiguous engagement, the recesses cooperate to define a cable opening for receiving a cable, and the projection is compressed between the gasket sections to seal the space between the gasket sections adjacent the cable opening. Preferably two laterally spaced integral sealing ribs are provided in each recess, which sealing ribs extend transversely completely across the recess and terminate at each end in a sealing projection that extends upwardly from the associated planar surface.

A terminal block assembly includes at each end a generally U-shaped support spring having leg portions that extend upwardly in straddling relation on opposite sides of the stationary resilient contacts at opposite ends of the bus bar, thereby to support the stationary contacts as insulated conductors are displaced by actuator members toward cutting engagement with knife edges on the adjacent ends of the reversely inwardly directed stationary resilient contacts.

A connector system includes a plurality of conductor piercing units supported by a frame for vertical displacement between upper disconnected and lower connected positions relative to a plurality of parallel spaced insulated conductors supported in a horizontal plane by a base plate. The piercing units are displaced between said upper and lower positions by operating disks eccentrically mounted for rotation on a horizontal support shaft that extends between an opposed pair of side walls of the frame. The base plate, frame and piercing unit assembly are arranged in an open-topped support housing that is closed by a cover member or lid. Electrical components may by mounted on the lid for connection with the piercing unit assembly.

An improved electrical connector is formed by stamping and bending a sheet of conductive metal, wherein as a preliminary step, a series of longitudinally-spaced openings are formed in the sheet to define a plurality of transversely extending strips from the side edges of which a pair of parallel spaced integral side walls extend, which sheet is coiled on a storage spool, and is subsequently unwound and fed toward a stamping station at which the transverse strips are severed at spaced separation points, thereby to define a connector body wall integral with the side walls. The side walls have portions that are simultaneously bent to form top, bottom and/or end walls which cooperate to define a chamber in which a spring contact is mounted. The connector is then connected an electrical component, such as a printed circuit board, in the manner of a surface mounted device (SMD).
