Electrical connector for coupling power leads to circuit boards

Claim 2

An electrical connector comprising: a generally flat, unitary member of electrically conductive material having at least one aperture therein for terminating at least one electrical conductor; means, affixed to said flat member in parallel rows, for electrically and mechanically coupling said member to a circuit board, each of said coupling means including a compliant portion at an intermediate point along its length for effecting frictional engagement between said coupling means and said circuit board, and a flexible terminal portion intermediate said compliant portion and said flat member, said flexible terminal portion having a length to a smallest cross-sectional width ratio greater than three and further having one end integral with said compliant portion and an opposite end affixed to said flat member, said flexible terminal portion providing a flexible connection between said compliant portion and said flat member; and means, affixed to said flat member at an intermediate point between said parallel rows of said coupling means, for counteracting shear stresses between said flat member and said circuit board upon the termination of said electrical conductor to said connector.

Claim 3

The electrical connector in accordance with claim 1 wherein said counteracting means comprises at least one studlike member fastened to and extending downwardly from said flat member, said studlike member having a longitudinal axis which is parallel with longitudinal axes of said coupling means.

Claim 4

The electrical connector in accordance with claim 2 wherein said compliant portion has a cross-sectional thickness which varies from a minimum thickness at endpoints to a maximum thickness at a midpoint.

Claim 5

The electrical connector in accordance with claim 3 wherein said compliant portion further includes tapered regions at points between said coupling means and said compliant portion, said tapered regions facilitating entry of said compliant portion into plated through holes in said circuit board.

Claim 6

The electrical connector in accordance with claim 4 further including means, integral with oppositely disposed edges of said flat member, for facilitating alignment between a terminated power lead and said connector.

Claim 7

The electrical connector in accordance with claim 5 wherein said facilitating means comprises a pair of raised lips.

Claim 8

An electrical connector comprising: a generally flat, unitary member of electrically conductive material having at least one aperture therein for terminating at least one electrical conductor; a plurality of pin contacts, affixed to said flat member in parallel rows, for electrically and mechanically coupling said flat member to a circuit board, each of said pin contacts including a compliant portion at an intermediate point along its length for effecting frictional engagement between said pin contacts and said circuit board, and a flexible terminal portion intermediate said compliant portion and said flat member, said flexible terminal portion having a length to a smallest cross-sectional width ratio greater than three and further having one end integral with said compliant portion and an opposite end affixed to said flat member, said flexible terminal portion providing a flexible connection between said compliant portion and said flat member; and at least one studlike member for counteracting shear stresses between said flat member and said circuit board upon the termination of said electrical conductor to said connector, said studlike member fastened to and extending downwardly from said flat member at an intermediate point between said parallel rows of said pin contacts and having a longitudinal axis which is parallel with longitudinal axes of said plurality of pin contacts.

Claim 9

An electrical connector comprising: a generally flat, unitary member of electrically conductive material having at least one aperture therein for terminating at least one electrical conductor; a plurality of pin contacts, affixed to said flat member in parallel rows, for electrically and mechanically coupling said flat member to a circuit board, each of said pin contacts including a compliant portion at an intermediate point along its length for effecting frictional engagement between said pin contacts and said circuit board, and a flexible terminal portion intermediate said compliant portion and said flat member, said flexible terminal portion having a length to a smallest cross-sectional width ratio greater than three and further having one end integral with said compliant portion and an opposite end affixed to said flat member, said flexible terminal portion providing a flexible connection between said compliant portion and said flat member; and at least one studlike member for counteracting shear stresses between said flat member and said circuit board upon the termination of said electrical conductor to said connector, said studlike member fastened to and extending downwardly from said flat member at an intermediate point between said parallel rows of said pin contacts and having a longitudinal axis which is parallel with longitudinal axes of said plurality of pin contacts.

Claim 10

The electrical connector in accordance with claim 7 wherein said compliant portion has a cross-sectional thickness which varies from a minimum thickness at endpoints to a maximum thickness at a midpoint.

Claim 11

The electrical connector in accordance with claim 8 wherein said compliant portion further includes tapered regions near oppositely disposed end portions to facilitate entry of said compliant portion into plated through holes in said circuit board.

Claim 12

The electrical connector in accordance with claim 9 further including means, integral with oppositely disposed edges of said flat member, for facilitating alignment between a terminated power lead and said connector.

Claim 13

The electrical connector in accordance with claim 10 wherein said facilitating means comprises a pair of raised lips.
