Abstract

A connector for electrically connecting a first conductor on a top surface of a first substrate with a second conductor on a top surface of a second substrate, when the second substrate is positioned beneath the first substrate, the connector includes an electrically conductive clip having a first prong and a second prong, with at least a portion each of the first and second prongs positionable at the top and bottom surfaces of the first substrate respectively, such that the first and second prongs provide a clipping force upon the first substrate to engage the first substrate with the clip. The connector further includes a first electrically conductive contact affixed to the first prong of the clip and is for contacting the first conductor when the clip engages the first substrate. An electrically conductive third prong is connected and extends from the clip, and includes a third electrically conductive contact affixed to the third prong for contacting the second conductor.

Claims

1. A connector for electrically connecting a first conductor, the first conductor being disposed on a top surface of a first substrate, with a second conductor, the second conductor being disposed on a top surface of a second substrate, when the second substrate is positioned beneath the first substrate such that the top surface of the second substrate faces in a direction towards a bottom surface of the first substrate, said connector comprising:

a substantially J-shaped clip for engaging the first substrate, said clip including a first prong, a second prong and a generally arcuate portion, said first and second prongs extending from said generally arcuate portion, said first prong comprises a first contact portion positionable upon the top surface of the first substrate for contacting the first conductor when said clip engages the first substrate and said second prong comprises a second contact portion positionable upon the bottom surface of the first substrate, said second contact portion for engaging the bottom surface of the first substrate;

said first prong comprises a lead in portion extended from said first contact portion to a top end portion, wherein said lead in portion of said first prong is bent away from said second prong;

a third prong connected to an end of said second prong distal to said generally arcuate portion, said third prong extending at a forward angle distal to said generally arcuate portion, said third prong comprises a third contact portion, and a lead in portion extended from said third contact portion to a top end portion, wherein said lead in portion of said third prong is bent toward said first prong, said third contact portion for maintaining contact with the second substrate and contacting the second conductor when a spacing between the first substrate and the second substrate is within a selected range;

an electrically conductive path electrically connecting said first contact portion and said third contact portion; and

said first prong forms a first arm of said clip, and said second and third prongs form a second arm of said clip, whereby said second arm has a longer length than said first arm.

2. A connector as recited in claim 1, wherein:

said first and second prongs provide a clipping force upon the first substrate to clippingly engage the first substrate with said clip when said first prong is positioned at the top surface of the first substrate and when said second prong is positioned at the bottom surface of the first substrate.

3. A connector as recited in claim 1, wherein:

said second prong extends from said arcuate portion towards said first prong.

4. A connector as recited in claim 1, wherein:

said electrically conductive path includes electrically conductive material integral with said clip and said third prong.

5. A connector as recited in claim 1, wherein:

said clip comprises an electrically conductive material.

6. A connector as recited in claim 5, wherein:

said first contact portion is integral with said first prong of said clip.

7. A connector as recited in claim 1, wherein:

said third prong comprises an electrically conductive material.

8. A connector as recited in claim 7, wherein:

said third contact portion is integral with said third prong.

9. A connector for electrically connecting a first conductor, the first conductor being disposed on a top surface of a first substrate, with a second conductor, the second conductor being disposed on a top surface of a second substrate, when the second substrate is positioned beneath the first substrate such that the top surface of the second substrate faces in a direction towards a bottom surface of the first substrate, said connector comprising:

a substantially J-shaped clip for engaging the first substrate, said clip including a first prong, a second prong and a generally arcuate portion, said first and second prongs extending from said generally arcuate portion, said first prong comprises a first contact portion positionable upon the top surface of the first substrate for contacting the first conductor when said clip engages the first substrate and said second prong comprises a second contact portion positionable upon the bottom surface of the first substrate, said second contact portion for engaging the bottom surface of the first substrate, said first contact portion and said second contact portion configured to provide a clipping force upon the first substrate to clippingly engage the first substrate with said clip;

said first prong comprises a lead in portion extended from said first contact portion to a top end portion, wherein said lead in portion of said first prong is bent away from said second prong;

a third prong connected to an end of said second prong distal to said generally arcuate portion, said third prong extending at a forward angle distal to said generally arcuate portion, said third prong comprises a third contact portion, and a lead in portion extended from said third contact portion to a top end portion, wherein said lead in portion of said third prong is bent toward said first prong, said third contact portion for maintaining contact with the second substrate and contacting the second conductor when a spacing between the first substrate and the second substrate is within a selected range;

an electrically conductive path electrically connecting said first contact portion and said third contact portion; and
