A socket assembly includes a housing with a plurality of through openings that extend between opposite surfaces of the housing. First and second plurality of contact members are positioned in a plurality of the through openings. The contact members each include major beams and minor beams with proximal ends attached to a center portion, and distal ends extending away from the center portion. The major beams preferably have a length greater than the minor beams. When the first circuit member is engaged with the socket assembly the ball grid array displaces the distal ends of the major beams to create a plurality of first and second forces. The first plurality of forces generally oppose the second plurality of forces. The first and second plurality of forces also generate an engagement force that biases the first circuit member toward the housing. The minor beams on the first and second plurality of contact members do not contribute to the engagement force.

A modular jack assembly for connecting and switching computer network cables. The jack assembly includes at least one jack module with two sets of connectors for linking wires from cables to the module and at least one jack. The modules within jack assembly slide between a first position and a second position. In the first position, the two sets of connectors linked to cables are electrically connected to each other, allowing normal through signals transmission. In the second position, the electrical connection between the connector sets is broken and the plug contacts within each jack are linked to one of the sets of connectors, allowing pass-through connections, such as a cross-connection, to be made.

Normal through jack and method

An improved flexible circuit connector that is particularly useful in connections for circuit boards has a housing and a circuit card engaging assembly mounted therein. The circuit card engaging assembly includes at least two contact spring members having a U-shaped portion adjoining a body portion thereof such that when the two contact spring members are brought together at their body portions, a U-shaped channel is formed that supports two lengths of flexible circuity close to the surface and edge of a circuit board inserted into the connector channel.

A modular jack assembly for connecting and switching computer network cables. The jack assembly includes at least one jack module with two sets of connectors for linking wires from cables to the module and at least one jack. The modules within jack assembly slide between a first position and a second position. In the first position, the two sets of connectors linked to cables are electrically connected to each other, allowing normal through signal transmission. In the second position, the electrical connection between the connector sets is broken and the plug contacts within each jack are linked to one of the sets of connectors, allowing pass-through connections, such as a cross-connection, to be made.

An information handling system includes stacks of printed circuit boards interconnected using an interconnection system. The printed circuit boards include network boards, system interface boards, memory boards, and central processing unit boards. The interconnection system for electrically connecting the various printed circuit boards includes a set of interconnection modules placed adjacent one another to form a substantially aligned row. The interconnection modules can be used to connect one stack to an orthogonally oriented stack or to a parallel oriented stack. The printed circuit board used in the interconnection system includes an inner rail positioned near the edge of the printed circuit board, an outer rail positioned near the edge of the printed circuit board, and an alignment stop attached to or positioned near one of the inner or outer rail. The most distant interconnection module of a row of aligned modules includes a spring attached thereto. The spring biases the set of interconnection modules toward the alignment stop to lessen the amount of stack up tolerance or float between the individual modules in the aligned row of interconnection modules. Electrical contact points located between the inner and the outer rail. The modules include alignment feet which have corresponding contact points. The inner and outer rail includes slots therein for clearance of the interconnection modules with the contact points.

A circuit card connector that utilizes flexible circuitry includes an elongated base, a pair of cradle spring members supported on the base, and a pair of contact springs movably supported on the cradle spring members. The cradle spring members include a plurality of reset arms that extend upwardly therefrom into contact with the undersides of the flexible circuitry. The flexible circuitry includes an apertured ground plane layer spaced apart from and located beneath the signal face layer. The apertures in the ground plane layer increase its flexibility especially at the interconnection interfaces to increase the compliance of the connector.

Microstrip edge card connector

A circuit card connector that utilizes flexible circuitry includes one or more isolator portions attached to its base that serve to substantially isolate the base of the connector from the circuit board to which the connector is mounted. The isolator portions include feet that extend out from the connector and which partially support the flexible circuitry. These isolator portions are made from thermally insulative material and serve to prevent heat transfer to the connector base from occurring during soldering of the flexible circuitry conductive portions to the circuit board.
