Abstract

A simple inexpensive electrical connector (and method of fabrication) for the connection of twisted pair or coaxial cable wires to adjacent pins extending from a backplane. A thin metallic strip is punched to form a plurality of pairs of flags extending from a common connector strip. The distance between the two flags of each pair is regulated to match the standard distance between terminal pins of the backplane. Each flag is punched with a central opening which forms teeth therein. The flags are preferably bent at the perimeter areas in order to form stiffening flanges and means for wire connection. Alternatively the flags are preferably encompassed by stiff plastic insulating material after the lead wires have been connected to each flag. A common connector strip which may be broken off and discarded, is used for handling with automatic equipment. A solid, reliable, durable and gastight connection is accomplished by pressing the connector over a pair of adjacent terminal pins which are bitten into by the toothed projections of the inner openings of each flag. Servicing and orderliness is facilitated since multiple sets of connectors can also be stacked on the same pair of terminal pins.

Dependent claims

An electrical connector for connecting a pair of wires, each wire carrying a different voltage level, to adjacent terminal pins on a backplane, comprising:

a. a pair of conductive flags, spaced a predetermined distance apart;
b. an opening centrally located in each flag of said pair of conductive flags;
c. a pair of bifurcated strips within each of said central openings to provide teeth for biting into the surface of a terminal pin inserted through said opening;
d. an insulating cover which integrally provides a hermetic seal to said pair of conductive flags and said pair of wires while rigidly maintaining said flags a predetermined distance apart, said insulating cover having openings oriented to expose the central opening of each flag and the ends of the teeth within the opening of each of said flags;
e. said insulating cover having one end provided with a shape distinguished from the shape of the other end to readily identify one wire of the twisted pair from the other wire in order to distinguish the level of each wire in the pair of wires, thus to reliably insure the proper voltage orientation and proper connection of the wires when connected on the terminal pins of said backplane;
f. each of said openings in said hermetically insulating cover providing sufficient exposed area about the central openings of the flag and about the teeth therein to permit bending of said teeth into contact against said backplane pins.
