Abstract
An electrical connector (20) adapted for engagement with a plated-through hole (13) in a printed circuit board (10) is disclosed. This connector includes first and second generally squared-shaped posts (21,22) for receiving electrically conductive elements. Intermediate these first and second posts is a compliant section (23,24,25,26) for producing an interference coupling between the connector and the plated-through hole. Juxtaposed the compliant section and intermediate and located between it and the first post is a broaching section (30) for conditioning the plated-through hole prior to engagement of the compliant section with the plated-through hole.
Claims9
An electrical connector (20) adapted for engagement with an inner surface of a plated-through hole (13) in an electrical circuit board (10) comprising:
- first and second means (21,22) for receiving electrically conductive elements;
- means (23,24,25,26), intermediate said first and second means, for providing an interference coupling between said connector and said plated-through hole characterized in that said connector further includes
- means (30), juxtaposed said interference coupling means and intermediate said first means and said interference coupling means, for conditioning a particular portion of the inner surface of said plated-through hole prior to engagement of said interference coupling means with the same particular portion of the inner surface of said plated-through hole.
An electrical connector (20) adapted for engagement with an inner surface of a plated-through hole (13) in an electrical circuit board (10) comprising:
- first and second spaced-apart generally square-shaped posts (21,22) for receiving electrically conductive elements;
- a compliant section (23) intermediate said first and second posts for providing an interference coupling between said connector and said plated-through hole, said compliant section gradually increasing in cross-sectional thickness from a first end point (24) to a midpoint (25) and thereafter gradually decreasing in cross-sectional thickness from said midpoint to a second end point (26) so as to produce a nearly uniform radial pressure on said plated-through hole upon insertion of said connector therein characterized in that said connector (20) further includes
- means (30), juxtaposed but separate from said compliant section (23) and intermediate said first post (21) and said compliant section, for conditioning substantially all of the inner surface of said plated-through hole (13) prior to engagement of said compliant section with said plated-through hole.
An electrical connector (20) adapted for engagement with an inner surface of a plated-through hole (13) in an electrical circuit board (10) comprising:
- first and second spaced-apart generally square-shaped posts (21,22) for receiving electrically conductive elements;
- a compliant section (23) intermediate said first and second posts for producing an interference coupling between said connector and said plated-through hole, said compliant section gradually increasing in cross-sectional thickness from a first end point (24) to a midpoint (25) and thereafter gradually decreasing in cross-sectional thickness from said midpoint to a second end point (26) so as to produce a nearly uniform radial pressure on said plated-through hole upon insertion of said connector therein characterized in that said connector (20) further includes
- a broaching section (31,32,33,34,35,36,37) juxtaposed said compliant section and intermediate said first post (21) and said compliant section (23) for ploughing out substantially all of the inner surface of said plated-through hole (13) prior to engagement of said compliant section with the inner surface of said plated-through hole.
