Filed:

Sep 28, 2000

Appl. No.:

09/672561

Inventors:

David Allison Trout - Wrightsville PA
Edmund Luther Jacobs - Harrisburg PA
Lewis Brian Lerner - Harrisburg PA
Michael Anthony Yeomans - Camp Hill PA

Assignee:

Tyco Electronics Corporation - Middletown PA

International Classification:

H01R 13625

US Classification:

439342

Abstract:

A zero insertion force socket is provided having a cover and housing slidably mounted to one another. The housing includes a pocket receiving a cam assembly. The cam assembly is slidably moveable within the housing in a direction perpendicular to the direction of movement between the cover and housing. The lever is rotatably mounted within the housing and engages the cam assembly to transfer rotational movement of the lever into axial movement of the cam assembly in a transverse direction. The cam assembly communicates with the cover such that the cam assembly drives the cover in a longitudinal direction as the cam assembly moves in a transverse direction. The lever and cam assembly cooperate to spread actuation forces across the cover and housing.

Assignee:

Tyco Electronics Corporation - Middletown PA

International Classification:

H01R 450

US Classification:

439342

Abstract:

A socket is provided for receiving electronic packages having different first and second sizes. The socket comprises a base housing having a top surface including an array of pin receiving chambers as well as base side walls. The socket also comprises a cover having a top surface including an array of holes corresponding to the array of pin receiving chambers. The cover also includes cover side walls that slidably engage the base side walls. Further, the socket comprises first and second locating members provided on at least one of the base housing and cover. The first locating member is positioned to engage and align an electronic package having a first size with the array of holes in the cover, and the second locating member is positioned to engage and align an electronic package of a second size with the array of holes in the cover.

Assignee:

Tyco Electronics Corporation - Middletown PA

International Classification:

H01R 13625

US Classification:

439342

Abstract:

A zero insertion force socket includes a cover which is movable along a longitudinal axis relative to a base housing. An actuation member is mounted for rotation about a rotation axis that is parallel to the longitudinal axis. The actuation member is operably connected for moving the cover along the longitudinal axis when the actuation member is rotated about the rotation axis. The actuation member may include a leg that extends along the rotation axis, and a handle that extends perpendicular to the leg. The leg includes at least one thread that is received in a recess in the cover.

International Classification:

H02G 314

US Classification:

174 66, 174138 F, 439135, 439940

Abstract:

A cover assembly is provided that includes an electronic socket with a socket cover having a bottom surface. The cover assembly includes a transport cover with a top surface and bottom surface. The top surface is configured to form a vacuum seal with a tool, and the bottom surface includes a locating post and a flexible beam with a protusion. The locating post is configured to engage the socket cover. The flexible beam is biased by the socket cover such that the protrusion releasably engages the bottom surface of the socket cover retain the transport cover to the socket cover.

Appl. No.:

10/008410

Inventors:

Richard Nicholas Whyne - Mechanicsburg PA
David Allison Trout - Wrightsville PA

Assignee:

Tyco Electronics Corporation - Middletown PA

International Classification:

H01R 450

US Classification:

439342

Abstract:

A terminal for use with a zero insertion force socket is disclosed which electrically connects a mating connector to a printed circuit board or the like. The terminal has a pin engaging portion which has a pair of nonsymmetrical contact arms which are positioned to make electrical engagement with the mating pin. A first contact arm of the pair of contact arms is configured to have a longer electrical path across which signals are transmitted than a second contact arm. The first contact arm also has a reduced cross section compared to the second contact arm, such that the first contact arm is configured to have a matched inductance to the second contact arm. A retention portion extends from the pin engaging portion. Side edges of the retention portion are dimensioned to create a frictional interference with side wall of a cavity of the socket. A mounting portion extends from the retention portion in an opposite direction from the pin engaging portion.

Inventors:

Nathan John Norris - Palmyra PA, US
Richard N. Whyne - Camp Hill PA, US
David A. Trout - Lancaster PA, US

Assignee:

Tyco Electronics Corporation - Middletown PA

International Classification:

H01R013/62

US Classification:

439342, 439259

Abstract:

A socket for an electronic package includes a cover and a base slidably joined with one another. A cam assembly drives the cover relative to the base between open and closed positions, and a bias element directly contacts the cam assembly to force the cam assembly to a fully open position when the cam assembly is moved from the closed position. The cam assembly is adapted for linear displacement relative to the base when actuated, and the bias element exerts a force on the cam assembly to locate the cover in the open position. The bias element is located between the cover and the base.
