Abstract
Abstract A rapid connector is utilized to effect electrical connections between individual wire ends from a multi-conductor cable to terminal pins on a terminal block such as might be located in a central telephone office. The connector comprises an insulative body having a plurality of wire receiving pins on one side to which the wire ends of the multi-conductor cable are connected at the factory or during the manufacture of the body. The other side of the body includes a plurality of terminal pin receiving openings. The cable pins extend into the body and terminate in spring fingers adjacent to the terminal pin receiving openings and cam means are provided for camming the spring fingers simultaneously into electrical contact with the terminal pins after the terminal pins have been received in the terminal pin receiving openings. Those openings are free of obstructions when the cam means are in unlocked position so that a large number of pins from the board can simultaneously be received in the pin openings with a minimum of friction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
A rapid connector for effecting electrical connection between individual wire ends from a multi-conductor cable to terminal pins on a terminal block, comprising, in combination: a. an insulative body having a plurality of wire receiving cable pins on one side for connection to the wire ends of said multiconductor cable and terminal pin receiving openings on its other side, said cable pins extending into said body and terminating in spring fingers adjacent to said terminal pin receiving openings; b. cam means in said body for camming said spring fingers simultaneously into electrical contact with said terminal pins after said terminal pins have been received in said terminal pin receiving openings whereby a plurality of electrical connections between conductors in said multi-conductor cable and said terminal pins can be made rapidly and simultaneously by said rapid connector; and in which c. said one side includes parallel shoulders running adjacent to said wire receiving cable pins defining a seat for accommodating an additional rapid connector in piggyback fashion, said cable pins being received in the pin receiving openings on the other side of said additional rapid connector.
Claim 2
Dependent Claim
185 words
A rapid connector for effecting electrical connection between individual wire ends from a multi-conductor cable to terminal pins on a terminal block, comprising, in combination: a. an insulative body having a plurality of wire receiving cable pins on one side for connection to the wire ends of said multiconductor cable and terminal pin receiving openings on its other side, said cable pins extending into said body and terminating in spring fingers adjacent to said terminal pin receiving openings; b. cam means in said body for camming said spring fingers simultaneously into electrical contact with said terminal pins after said terminal pins have been received in said terminal pin receiving openings whereby a plurality of electrical connections between conductors in said multi-conductor cable and said terminal pins can be made rapidly and simultaneously by said rapid connector; and in which c. said one side includes parallel shoulders running adjacent to said wire receiving cable pins defining a seat for accommodating an additional rapid connector in piggyback fashion, said cable pins being received in the pin receiving openings on the other side of said additional rapid connector.
Claim 3
Dependent Claim
114 words
A connector according to claim 1, in which said insulative body includes enlarged internal cavities communicating with said pin receiving openings, said cam means extending between said cavities and said spring fingers terminating respectfully in said cavities and being biased against said cam means to one side of said cavities so that said cavities are cleared of any obstructions when receiving said terminal pins whereby friction when said terminal pins are received in said openings is minimized, operation of said cam means urging said spring fingers laterally towards the opposite sides of the cavities to thereby electrically engage said terminal pins and sandwich them between the spring finGers and opposite sides of the cavities.
Claim 4
Dependent Claim
32 words
A connector according to claim 2, in which said insulative body includes 200 pin receiving openings, each of said openings having beveled entrance portions to facilitate initial insertion of the pins therein.
Claim 5
Dependent Claim
103 words
A connector according to claim 2, in which said cam means comprises an elongated insulated member running through said body in a direction normal to the direction of the cable pins to pass between adjacent pairs of rows of spring fingers in said cavities, the cross-section of said member being elongated such that rotation of said member about its own axis through 90* rotates the long dimension of said cross-section from a position parallel to the cable pins to a position transverse to the cable pins whereby the ends of the long dimension of cross-section cam the spring fingers against said terminal pins.
Claim 6
Dependent Claim
78 words
A connector according to claim 4, in which each of said spring fingers bows inwardly towards said cam member, thence extends outwardly over a major portion of its length then turns inwardly at its tip to define a rounded contact surface facing outwardly to engage a terminal pin, the movement of the spring finger upon operation of said cam means providing a wiping action as well as a normal pressure against the terminal pin by said contact surface.
Claim 7
Dependent Claim
38 words
A connector according to claim 5, in which said cam member is rotatable slightly more than 90* so that an over-centering action takes place, the resiliency of said spring fingers holding the cam member in its locked position.
Claim 8
Dependent Claim
61 words
A connector according to claim 5, in which said body includes a plurality of rows of cable pins, there being provided cam means between pairs of adjacent rows, the ends of said cam means being exposed at the ends of said body and including screw driver slot means for enabling rotation of the cam means from either end of said body.
