摘要:
A connector arrangement for tapping off current from a plurality of insulated input conductors includes a rectangular base member having a horizontal planar upper surface provided with a plurality of parallel seats receiving the insulated conductors, a frame mounted on the base member for supporting a plurality of terminal blocks for vertical displacement over the seats, each terminal block including an insulation piercing contact extending downwardly therefrom, and an eccentric disk arrangement for displacing each terminal block relative to the frame member between an elevated position spaced above the associated conductor seat and a lowered position in which the contact penetrates the insulation layer and engages the conductor, thereby to transmit current to an output conductor via the insulation-piercing conductor, a bus bar, and a tap-off terminal.

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.

摘要:
A modular control system for connecting the electrical components of an automated system, such as switches, sensors, reactors and field units, with a master field bus system via an assembly of terminal blocks mounted on a grounded support rail, characterized in that the assembly includes a power supply terminal block, a ground terminal block, and at least one control signal terminal block for supplying control signals to control circuits carried by printed circuit boards contained within a removable electronics module. The various terminal block assemblies mounted on a given support rail are connected via internal bus bar means that is connected by a module with the master field bus.
摘要:
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.

An electrical connector arrangement taps off electrical current from a plurality of coplanar parallel input insulated conductors and supplies the same to a plurality of output conductors, respectively. A rectangular base member is provided having a horizontal upper surface that supports a plurality of parallel coplanar longitudinally-extending input conductors, respectively. A pair of pivot members are connected with the ends of the base member for pivotal movement about transverse horizontal pivot axes, respectively. As the pivot members are pivoted from disengaged positions toward engaged positions parallel with and directly above the base member top surface, bifurcated insulation-piercing knives on the pivot members pierce the insulation layers of the insulated conductors and electrically engage the conductors. Junction blocks fastened to the pivot members include output contacts connected with the insulation piercing knives via bus bars, which output contacts are connected with the output conductors, respectively.
