Abstract:

A high current capacity socket ( ) includes a base ( ) and a number of side contacts ( ). The base includes a bottom plate ( ), a pair of sidewalls ( ) extending upwardly from opposite sides of the bottom plate. A number of passageways ( ) are defined in the bottom plate and corresponding terminals ( ) are received in the passageways. A receiving room ( ) is defined in the center of the bottom plate. The side contacts are fixed in the sidewall ( ) of the base ( ) to transmit current to a printed circuit board or grounded to reduce the dimension of an integrated circuit package that is received in the receiving room.

US Classification:

439342, 439259

Abstract:

An electrical connector ( ) includes a base ( ) securely assembled to a printed circuit board, a number of terminals ( ) received in the base, a cover ( ) moveably assembled to the base and a driving device ( ). The cover defines a number of through holes ( ) for extension of corresponding pins ( ). The driving device is arranged between the base and the cover to move the cover between first and second positions. The base defines a lever rest ( ) which defines a central slot ( ) having a recess ( ). The driving device includes a driving shaft ( ) and a follower ( ). The driving shaft has a helical section ( ) and a bearing section ( ). The bearing section bears against a central slot in a first direction and an edge of the helical section pushing the follower in an opposite second direction during an actuation stroke of the driving shaft.

Assignee:

Hon Hai Precision Ind. Co., Ltd. - Taipei Hsien

International Classification:

H01R 450

US Classification:

439342, 439884

Abstract:

An electrical connector includes an insulative housing defining a number of channels each receiving and retaining a conductive contact. The contact includes a base section having upper and lower edges and opposite side edges connecting the upper and lower edges. Barbs are formed on side edges of the base section to interferentially retain the contact in the channel. Two support sections that are made slim and thus relatively flexible extend from the upper edge of the base section. The support sections are spaced from each other and forms a common plane with the base section. An arm that is relatively rigid extends from each support section in a direction substantially normal to the common plane. The arms are arranged to face each other. The arms are spaced from the upper edge of the base section different distances whereby the arms are staggered with respect to each other.

Assignee:

Hon Hai Precision Ind. Co., Ltd. - Taipei Hsien

International Classification:

H01R 1362

US Classification:

439342, 439259

Abstract:

An electrical socket ( ) for supporting an integrated circuit chip on a circuit board mainly comprises a non-conductive base ( ), a plurality of conductive contacts ( ) retained in the base, a slidable cover ( ) and an actuator member ( ) for moving the slidable cover with respect to the base. The base defines a receiving space ( ) for receiving the actuator member and a recessed portion ( ) adjacent to the receiving space. The cover forms a projection member ( ) which projects from a bottom surface thereof beyond an adjacent side edge thereof to be slidablely received in the recessed portion. The actuator member pushes the projection member to move to its predetermined closed position where the pins of the integrated circuit chip are electrically connected with the conductive contacts, once it is worn after being repeatedly operated or the cover creeps.
