Abstract
Abstract A connecting device for use in a visual display unit to electrically connect a pair of substrates with one another and with a printed circuit board. The device includes a body portion for insertion into a socket or hole of the printed circuit board, a transverse bar providing a seating surface for engaging the board, and a pair of contact elements which are urged by spring action against conductive strips on the substrates.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
372 words
A device for providing electrical and physically supporting connection between a connector having a socket and a substrate assembly including first and second insulating substrate panels having opposed electrically conductive portions spaced apart from one another within a recess formed between free edge portions of the substrate panels, said device comprising: a stem portion having a contact body adapted for insertion into the socket of the connector to make electrical contact therewith, said stem portion having a seating surface engaging the connector when said contact body is inserted into the socket; a generally flat base plate connected with said stem portion; a bridge portion extending from said base plate and having a length to span the free edge portion of the first substrate panel; a first plate like contact element extending from said bridge portion in a generally parallel relationship with said base plate and spaced therefrom; a second plate like contact element forming a spring arm extending from said first contact element; a curved connecting portion integral with said first and second contact elements and connecting said contact elements in a manner to locate said second contact element in a position substantially folded over said first contact element about said connecting portion, said first and second contact elements being urged apart about said connecting portion by compression spring action when said contact elements are compressed toward one another; said first and second contact elements being insertable into said recess in electrical contact with said conductive portions of the respective first and second substrate panels with said bridge portion spanning the free edge portion of the first panel and said base plate and first contact element gripping the first panel therebetween, said contact elements being compressed when inserted into the recess whereby the contact elements are urged apart against said conductive portion of the panels; and said stem portion, contact body, base plate, bridge portion and contact elements being formed of an electrically conductive material to establish electrical connection between the conductive portions of the panels and between each conductive portion and said connector and to physically support the substrate assembly from the connector when said contact elements are inserted into the recess and said contact body is inserted into the socket.
Claim 2
Independent Claim
372 words
A device for providing electrical and physically supporting connection between a connector having a socket and a substrate assembly including first and second insulating substrate panels having opposed electrically conductive portions spaced apart from one another within a recess formed between free edge portions of the substrate panels, said device comprising: a stem portion having a contact body adapted for insertion into the socket of the connector to make electrical contact therewith, said stem portion having a seating surface engaging the connector when said contact body is inserted into the socket; a generally flat base plate connected with said stem portion; a bridge portion extending from said base plate and having a length to span the free edge portion of the first substrate panel; a first plate like contact element extending from said bridge portion in a generally parallel relationship with said base plate and spaced therefrom; a second plate like contact element forming a spring arm extending from said first contact element; a curved connecting portion integral with said first and second contact elements and connecting said contact elements in a manner to locate said second contact element in a position substantially folded over said first contact element about said connecting portion, said first and second contact elements being urged apart about said connecting portion by compression spring action when said contact elements are compressed toward one another; said first and second contact elements being insertable into said recess in electrical contact with said conductive portions of the respective first and second substrate panels with said bridge portion spanning the free edge portion of the first panel and said base plate and first contact element gripping the first panel therebetween, said contact elements being compressed when inserted into the recess whereby the contact elements are urged apart against said conductive portion of the panels; and said stem portion, contact body, base plate, bridge portion and contact elements being formed of an electrically conductive material to establish electrical connection between the conductive portions of the panels and between each conductive portion and said connector and to physically support the substrate assembly from the connector when said contact elements are inserted into the recess and said contact body is inserted into the socket.
Claim 3
Dependent Claim
76 words
A device as set forth in claim 1, including a second seating surface on said stem portion spaced from the first mentioned seating surface, said stem portion being frangible between the first and second seating surfaces to break the first seating surface away from the stem portion, whereby the stem portion can then be inserted into the socket until the second seating surface engages the connector to vary the spacing between the substrate assembly and connector.
Claim 4
Dependent Claim
30 words
A device as set forth in claim 1, including opposite side edges of said first and second contact elements and said connecting portion forming continuous, uninterrupted extensions of one another.
