Filed:

Oct 19, 2007

Appl. No.:

11/875426

John Mark Myer - Millersville PA, US
Barry Gene Burkepile - Kernersville NC, US
Leo Joseph Graham - Hershey PA, US

Assignee:

Tyco Electronics Corporation - Middletown PA

International Classification:

H01R 13/11

US Classification:

439852

Abstract:

An electrical contact includes a mating portion and a crimp portion connected by a transition region. The mating portion is configured to receive a mating external contact pin. The mating portion has a top wall and a bottom wall joined by opposing side walls. The top, bottom and side walls form a contact box open at one end. The contact box includes a contact beam that extends through the contact box, a front flap portion and a front aperture for insertion of the mating contact, and a back aperture adjacent to the transition region. The front flap portion protrudes partially into the front aperture forward of the contact beam to prevent a free end of the contact beam from receiving a direct impingement force when mating the electrical contact with the second electrical contact.

International Classification:

H01R 13/46

US Classification:

439892

Abstract:

A connection member includes a tube extending a length along a central longitudinal axis. The tube includes a central passageway that extends through the length of the tube. The tube has a non-circular cross-sectional shape along the length of the tube. The tube includes an exterior side that defines a perimeter of the non-circular cross-sectional shape of the tube. Stamped threads are formed on the exterior side of the tube along at least a portion of the length of the tube. The stamped threads are discontinuous along the perimeter of the non-circular cross-sectional shape of the tube such that the stamped threads only extend along at least one portion of the perimeter of the non-circular cross-sectional shape of the tube.

International Classification:

H01R 13/02

US Classification:

439890

Abstract:

A contact having a contact body that has a front, a rear and opposite sides that extend between the front and the rear. The contact body extends between a mating end and a mounting end. The mating end is configured to be mated with a corresponding mating contact. The mounting end is configured to be through-hole mounted to a printed circuit board. The mounting end has a profiled section that defines a compliant pin. The profiled section has a necked-down portion being thinner between the front and the rear than adjacent portions of the contact body. The profiled section has an opening through the necked-down portion. The profiled section has a compliant portion at the opening. The compliant portion is wider between the sides than adjacent portions of the contact body.

F28F 9/00

Abstract:

A thermal bridge includes an upper bridge assembly including upper plates arranged in an upper plate stack and a lower bridge assembly including lower plates arranged in a lower plate stack. The thermal bridge includes upper spring elements extending from upper plates having upper mating interfaces engaging lower plates to bias the upper plates in a first biasing direction generally away from the lower bridge assembly. The thermal bridge includes lower spring elements extending from lower plates having lower mating interfaces engaging upper plates to bias the lower plates in a second biasing direction generally away from the upper bridge assembly. A bridge frame having connecting elements extends through the upper plates and the lower plates to hold the upper plates in the upper plate stack and to hold the lower plates in the lower plate stack.

International Classification:

H01R 13/533

Abstract:

A heat sink assembly includes an upper heat sink element having upper plates each having sides between front and rear ends and each having inner and outer ends and a lower heat sink element having lower plates each having sides between front and rear ends and each having inner and outer ends. The lower plates include lower spacer plates and lower interface plates with the outer ends thereof thermally coupled to an electronic module. The lower interface plates include interface fins interfacing with the upper plates. The heat sink assembly includes a spring element having an upper spring member engaging the inner ends of the upper plates to bias the upper plates in a first biasing direction away from the lower plates and having a lower spring member engaging the inner ends of the lower plates to bias the lower plates in a second biasing direction away from the upper plates.

Abstract:

A connector assembly includes a cage member having a plurality of walls defining a module cavity for a pluggable module. The walls include a top wall, a bottom wall and side walls extending between the top and bottom walls. The side walls extend to a bottom edge at the bottom wall and include mounting pins extending from the bottom edge that each have a press-fit portion configured to be press fit in a plated via of a circuit board. The bottom wall has a generally planar bottom surface facing the circuit board and a generally planar top surface facing the module cavity. The bottom wall includes a locating feature extending below the bottom surface and having a datum surface configured to engage the circuit board. The datum surface is a predetermined distance from the top surface to set a position of the top surface relative to the circuit board.
