Abstract
A socket contact (1) for receiving a pin contact (4) of small diameter, especially a contact pin of a PCMCIA plug. The socket contact is formed of sheet metal and has a substantially flat base (5), a spacing part (6) extending upward from the front end of the base, and a top contact part (9) extending rearward from the top of the spacing part. The spacing part has a circular hole (7) for passing the pin contact until the pin contact is pressed upward by a tongue (8) formed in the base and is pressed downward by the top contact part. To prevent bending of the spacing part when the tongue and top contact part apply a large clamping force to the pin, the spacing part is formed with support regions (40, 42) where sheet metal at opposite sides of the spacing part are bent to extend rearwardly.
Claims7
A socket contact for receiving a pin contact, where the socket contact includes a piece of sheet metal forming a base with a flat base part that is elongated in front and rear longitudinal directions and that has laterally spaced opposite sides and that lies in a horizontal plane and has a base part front end, a spacing part formed by a piece of said sheet metal that extends upward from said base part front end and that has a top, said spacing part having a longitudinally-extending opening for passing said pin contact and having laterally-spaced opposite sides, and a top contact part extending primarily rearward from said top of said spacing part, said base forming a tongue with a contact location lying above said base part and below said top contact part, wherein:
- said spacing part has a pair of support regions that extend at least partially rearwardly and away from each other from locations at said laterally opposite sides of said spacing part, as seen in a downward sectional view taken through a middle of the height of said spacing part, to thereby strengthen said hole-forming spacing part against bending;
- said hole is circular and has a width and has a longitudinally-extending axis, and said spacer has a square center portion (30) with front and rear surfaces each lying in a vertical plane that is normal to said axis and that forms said hole, with said center portion having top and bottom edges extending along the entire width of said hole;
- said spacing part has a top region that extends at a rearward-upward incline from said top edge of said center portion, and has a bottom region that extends at a rearward-downward incline from said bottom edge of said center portion.
A socket contact for receiving a pin contact, where the socket contact includes a piece of sheet metal forming a base with a flat base part that is elongated in front and rear longitudinal directions and that has laterally spaced opposite sides and that lies in a horizontal plane and has a base part front end, a spacing part formed by a piece of said sheet metal that extends upward from said base part front end and that has a top, with said spacing part having a longitudinally-extending opening for passing said pin contact and having laterally-spaced opposite sides, and a top contact part extending primarily rearward from said top of said spacing part, said base forming a tongue with a contact location lying below said top contact part, wherein:
- said spacing part has a pair of support regions that extend at least partially rearwardly and away from each other from locations at said laterally opposite sides of said spacing part, as seen in a downward sectional view taken through a middle of the height of said spacing part, to thereby strengthen said hole forming spacing part against bending;
- said top contact part forming a beam that extends at a rearward-downward incline from the top of said spacing part by a distance that is at least half as great as the vertical height of said spacer part.
A socket contact for receiving a pin contact element, where the socket contact includes a piece of sheet metal forming a flat base that is elongated in front and rear longitudinal direction and that has laterally spaced opposite sides and that lies in a horizontal plane and has a front end, a spacing part that extends upward from said front end of said base and that has a top with said spacing part having an opening for passing said pin contact element, and a top contact part extending primarily rearwardly from said top of said spacing part, said base forming a tongue that extends at an upward incline and that has a contact location lying below said top contact part to clamp the pin contact element between them, wherein:
- said top contact part forms a beam that extends at a downward and rearward incline from the top of said spacing part and that has a contact point near a rear end of said top contact, with a length of said top contact part being at least half the height of said spacing part.
A socket contact for receiving a pin contact, where the socket contact includes a piece of sheet metal forming a base with a flat base part that is elongated in front and rear longitudinal directions and that has laterally spaced opposite sides and that lies in a horizontal plane and has a base part front end, a spacing part formed by a piece of said sheet metal that extends upward from said base part front end and that has a top, with said spacing part having a longitudinally-extending opening for passing said pin contact and having laterally-spaced opposite sides, and a top contact part extending primarily rearward from said top of said spacing part, said base forming a tongue with a contact location lying above said base part and below said top contact part, wherein:
- said spacing part has a pair of support regions that extend at least partially rearwardly and away from each other from locations at said laterally opposite sides of said spacing part, as seen in a downward sectional view taken through a middle of the height of said spacing part, to thereby strengthen said hole-forming spacing part against bending.
