A conductive contact (200) for electrically connecting with a chip module and a printed circuit board comprises a base portion (50), a top head portion (60) formed above the base portion adapted for connecting with a belt, at least one spring arm (70) extending sidewardly from the base portion and forming at least one contacting section (703) adapted for elastically contacting with the chip module, and a bottom soldering portion (80) extending form at least one of the base portion and the spring arm adapted for being soldered to the printed circuit board. The head portion defines a cutout (601) recessed downwardly from a top edge (602) thereof to reduce connecting length between the head portion and the belt and reduce siphonic effect when plating the spring arm.

A socket assembly, comprising a socket, a package received in the socket, a pressing member arranged upon the package and downwardly pressing the package and two heat pipes attached to the pressing member. The pressing member is formed with four arch grooves along a peripheral thereof, and the arch grooves allow linking members to pass therethrough and rotatablely retain the pressing member on a printed circuit board. Therefore, the pressing member can rotate in a certain range, by sliding the arch groove with respect to the linking member, to provide a flexible arrangement for heat pipes.

An electrical contact adapted for use in an electrical socket comprises a planar retaining body for being retained in the electrical socket, a soldering portion extending from a bottom end of the retaining body, and a resilient arm extending from a top end of the retaining body. The resilient arm comprises a first beam sloped upwardly and a second beam extending upwardly and reversely from the first beam. The first beam has a first angle with respect to a plane of the retaining body and a second angle with respect to another plane both perpendicular to the plane of the retaining body and a horizontal plane. The second beam has a contacting end at the top end thereof and toward the retaining body. An offset is defined between the contacting end of the resilient arm and the soldering portion.

An electrical connector assembly for electrically connecting a printed circuit board and an electronic package, comprises an electrical connector on which the electronic package is mounted, a heat sink module mounted upon the electronic package and a clip positioned upon the heat sink module. The printed circuit board defines a connector mounting area surrounded by a plurality of through holes thereof. The clip has a base portion downwardly pressing against the heat sink module, a pair of mounting portions mounted to the corresponding holes, and a pair of pressing portions extending from the mounting portions and disposed on opposite sides of the clip for pressing against the heat sink module.
摘要:
An optical fiber inclinometer comprises a pair of fiber Bragg grating devices, a fixed base, a connection plate, and a rotatable base. One end of the connection plate is fixed to the fixed base, whereas the other end of the connection plate is connected to the rotatable base through the joint of a turning pair mechanism between them. The two ends of each fiber Bragg grating device are installed onto the fixed base and the rotatable base respectively, and the two devices are mounted on the opposite side of the connection plate. Once the rotatable base rotates around the joint of the connection plate, axial tensile elongation occurs in one of the fiber Bragg grating devices, whereas axial compressive deformation occurs in the other device. The rotation angle of the rotatable base relative to the connection plate can be obtained by measuring and calculating the Bragg wavelength drifts of the pair of fiber Bragg grating devices respectively.
