Structure of bus-bar type electrical connector

Claim 1

A structure for a bus-bar type electrical connector, comprising: a base, having a dovetail groove at a bottom side with a plurality of elongated groves made thereon and longitudinally disposed in parallel with one another, two opposite supports at a top surface with a row of vertical slots defined therebetween, said two opposite supports each having a transverse groove on an outer side at a bottom thereof, said elongated grooves each having an end disposed in communication with said vertical slots and a wider opening at an opposite end, and two stepped edges at two opposite sides respectively in parallel with said transverse groove on said two opposite supports; an electrical contact assembly integrally comprised of a plurality of conductors respectively fastened in said elongated grooves of said base, said conductors each comprising an elongated, curved, conductive spring plate terminating in a forked end inserted through said slots from the bottom to respectively protrude beyond the top surface of said base, said spring plate having an inverted V portion at an opposite end and respectively retained in the wider opening of said elongated grooves, said forked end having an unitary strip extending downward at a middle region to secure said forked end in said slots: a ribbon cable fastener, comprising two opposite openings for insertion therethrough of said two opposite supports and a plurality of holes respectively in alignment with said slots, and two opposite hook portions extending downward therefrom at two opposite ends for engaging in either said two transverse grooves on said two opposite supports or said two stepped edges on said base, said two opposite hook portions having each a cut transversely made on an outer wall surface at a bottom thereof; a stress eliminator being substantially an M-shaped block, having two openings at two opposite ends defining therewith two opposite hook portions transversely disposed at the bottom; wherein said ribbon cable fastener can be disposed at a ready position with its two opposite hook portions respectively engaged in the two transverse grooves on said two opposite supports for mounting a ribbon cable on top of said forked ends of said electrical contact assembly and firmly squeezed downward against said base permitting said forked ends of said electrical contact assembly to respectively pierce through said ribbon cable so as to respectively firmly retain the conductors in said ribbon cable for electrical contact.
