Apparatus for wiring electrical terminals of electrical devices or systems

Abstract

For automatic wiring of terminals of electrical apparatus, for example fluorescent lamp luminaires, a line or wire-laying tool is used which has a finger ( ) on which a pressure element ( ), movable between three positions I, II, III with respect to the finger, and the terminal, respectively, is retained. The pressure element presses a wire ( ) in an insertion slit ( ) of a slit blade insulation piercing connector SBIPC ( ). The pressure element ( ) has a cutter blade at an end surface, and further has two pressure sections ( ). One section ( ) is used to effect a connection at the beginning of a wire run, or for through-wiring, and the other ( ) is used to terminate the end of a wire line, and to cut the wire. The finger ( ) is always outside of a contacting zone ( ), thus permitting miniaturization of the terminal to a degree limited only by insulation requirements of air or creep paths between adjacent SBIPCs. The terminals can thus be fitted into a raster, and are formed with grooved extensions ( ) to form wire retention and introduction slots.
