Abstract
Abstract This invention is directed to an electrical connector, particularly an electrical ballast connector, that offers a reliable means preferably to extract electrical conductors therefrom. The connector comprises a dielectric housing having a plurality of cavities therein extending between a contact loading face and a conductor receiving face, where the conductor receiving face includes an aligned row of conductor openings of a like plurality, where each opening includes a lateral slot in communication with the cavities. A stamped electrical contact is provided within each cavity, where said contact includes a base and a pair of spaced apart arms upstanding therefrom, where the inner edge of a first arm is aligned with its corresponding conductor opening, and the other arm includes an angular extension directly downwardly and toward the first arm. The end most edge of the other arm is aligned with and exposed to its corresponding conductor opening, and at least a portion of the angular extension is exposed to its corresponding lateral slot, whereby an extraction member may be received in the lateral slot to laterally flex or pivot the angular extension to provide a free path for the electrical conductor so as to remove the electrical conductor from contact with said inner edge. Finally, antioverstressing means are provided to limit the flexing or pivotal action of the angular extension.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
230 words
In an electrical connector of the type allowing for the individual or mass loading and extraction of electrical conductors therefrom, where said connector includes a plurality of cavities therein extending longitudinally between a contact loading face and a conductor receiving face, where said conductor receiving face includes an aligned row of conductor openings of a like plurality communicating with said cavities, and a stamped electrical contact within each said cavity, said contact including a base and a pair of spaced apart arms upstanding therefrom, where the inner edge of a first arm is aligned with its corresponding conductor opening, and the other arm includes an angular extension directed downwardly and toward said first arm, where the end most edge thereof is aligned with and exposed to its corresponding conductor opening, the improvement comprising in combination therewith the provision that each said contact is planarly aligned in a direction transverse to said longitudinal direction, and that said angular extension is arranged to flex within the plane of said contact upon loading and extracting conductors therefrom, and a lateral slot extending from each said conductor opening for receiving an externally applied extraction member, whereby said extraction member may be received in said lateral slot to laterally flex said angular extension to provide a free path for said electrical conductor so as to remove said electrical conductor from contact with said inner edge.
Claim 2
Dependent Claim
230 words
In an electrical connector of the type allowing for the individual or mass loading and extraction of electrical conductors therefrom, where said connector includes a plurality of cavities therein extending longitudinally between a contact loading face and a conductor receiving face, where said conductor receiving face includes an aligned row of conductor openings of a like plurality communicating with said cavities, and a stamped electrical contact within each said cavity, said contact including a base and a pair of spaced apart arms upstanding therefrom, where the inner edge of a first arm is aligned with its corresponding conductor opening, and the other arm includes an angular extension directed downwardly and toward said first arm, where the end most edge thereof is aligned with and exposed to its corresponding conductor opening, the improvement comprising in combination therewith the provision that each said contact is planarly aligned in a direction transverse to said longitudinal direction, and that said angular extension is arranged to flex within the plane of said contact upon loading and extracting conductors therefrom, and a lateral slot extending from each said conductor opening for receiving an externally applied extraction member, whereby said extraction member may be received in said lateral slot to laterally flex said angular extension to provide a free path for said electrical conductor so as to remove said electrical conductor from contact with said inner edge.
Claim 3
Dependent Claim
33 words
The improved electrical connector according to claim 1, wherein each said contact includes a lance projecting therefrom, where said lance is adapted to engage the cavity wall to fixedly engage said contact therewithin.
Claim 4
Dependent Claim
33 words
The improved electrical connector according to claim 1, wherein the said other arm of the contact is spaced from the cavity inner wall to allow flexing movement thereof during extraction of the conductor.
Claim 5
Dependent Claim
23 words
The improved electrical connector according to claim 1, wherein said lateral slots are joined by a slot longitudinally coextensive with said conductor openings.
Claim 6
Dependent Claim
23 words
The improved electrical connector according to claim 4, wherein said extraction member is a bladed tool to be received in said longitudinal slot.
Claim 7
Dependent Claim
35 words
The improved electrical connector according to claim 1, wherein the conductor contact portion of said angular extension is a formed arm projecting laterally therefrom to provide a conductor contact edge for engagement with said conductor.
Claim 8
Dependent Claim
37 words
The improved electrical connector according to claim 6, wherein said angular extension includes an arm extending from said conductor contact edge toward said other arm to provide a stop thereby limiting the flexing of said angular extension.
Claim 9
Dependent Claim
27 words
The improved electrical connector according to claim 1, wherein said angular extension is twisted about 90° to provide a conductor contact edge for engagement with said conductor.
Claim 10
Dependent Claim
32 words
The improved electrical connector according to claim 8, wherein said other arm includes a projection extending toward said contact arm to provide a stop thereby limiting the flexing of said angular extension.
