Abstract: PROBLEM TO BE SOLVED: To reduce crosstalk by positioning an elastic arm of a second terminal within the cross section of an elastic arm of a first terminal in the length direction of a dielectric housing when a circuit board is inserted into a card slot and the elastic spring arms of the first and second terminals are deformed. SOLUTION: An elastic spring arm 40c of a signal terminal is positioned within the cross section in the length direction of an elastic spring arm 38c of an earthed terminal, parallel to the elastic spring arm 38c and slightly narrow. A finger part 40e is positioned within the cross section in the length direction of an enlarged head 38e, and an enlarged supporting part 40g is positioned within the cross section in the length direction of a shield 38g. The shape in the whole construction of a signal terminal 40 is positioned within the cross section in the length direction of the earthed terminal 38, the earthed terminal 38 is positioned in the shadow of the signal terminal 40 or laid down on the signal terminal 40. Therefore, good signal/capacitive coupling is formed between both terminals, bonding between signals is decreased, and crosstalk of a connector is substantially decreased.

Abstract: PROBLEM TO BE SOLVED: To provide an improved edge card connector system, which provides a more adjusted operating impedance level.
SOLUTION: Circuit boards to which such high speed differential signal connectors are mounted are disclosed and they have a particular pattern of termination traces, commonly taking the form of plated vias extending through the circuit board. These vias are arranged in a triangular pattern and the ground reference plane of the circuit board is provided with voids, one void being associated and encompassing a pair of the differential signal vias of a single terminal triplet. This reduces the capacitance of the signal vias and thereby increases the impedance of the circuit board within the launch area to lessen impedance discontinuities in the connector-circuit board interface.

Abstract: PROBLEM TO BE SOLVED: To provide a novel and improved substrate-to-substrate connector in which a power supply terminal is incorporated in a connector part that is not conventionally used for connection. SOLUTION: A substrate-to-substrate connector 10 is provided with two male type and female type connector parts 18, 16 engaged with each other in which a power supply terminal and circuit terminals 52, 82, 38, and 74 are integrally incorporated. Each of the connector parts is provided with male type and female type housings 60, 20 spaced substantially parallel to each other. These housings 60, 20 are uniformly spaced by spacer members 80 and 50, and these spacer members 80, 50 extend between the housing 60, 20 and connect these with each other. The spacer members 80, 50 may be integrally molded with the housings 60, 20 or may be molded independently of the housings 60, 20 or may include a slot and a rag for engaging them. For the spacer members 80, 50 power supply terminals 82, 52 are disposed, and connection is formed between power supply circuits as well as between signal circuits of circuit boards 12, 14.

Abstract: A processor mounted to a circuit board is provided with regulated voltage through lower-inductance circuit board traces by mounting a voltage regulator module for the processor, on the side of the circuit opposite to the processor. Current from the voltage regulator is provided to the processor by way of one or more conductors between the regulator and processor that extend through the circuit board from one side to the other. Inductance attributable to lead length is reduced by locating the voltage regulator close to its load. Circuit board space on the processor side of the circuit board is increased by moving the voltage regulator to the opposite side.

Abstract: A differential signal connector that is used for edge card application has a plurality of differential signal terminals and associated ground terminals arranged in "triplets", i.e., distinct sets of three conductive terminals, each such triplet including a pair of differential signal terminals and one associated ground terminal. The ground terminal is flanked by the two differential signal terminals and each triplet is spaced apart from an adjacent triplet by a spacing which is greater than any single spacing between adjacent terminals within a triplet. Circuit boards to which such a connector is mounted are also disclosed and they have a particular pattern of termination traces, commonly taking the form of plated vias extending through the circuit board. These vias are arranged in a triangular pattern and the ground reference plane of the circuit board is provided with voids, one void being associated and encompassing a pair of the differential signal vias of a single terminal triplet. This reduces the capacitance of the signal vias and thereby increases the impedance of the circuit board within the launch area to lessen impedance discontinuities in the connector-circuit board interface.

Abstract: A system for delivering power to an integrated circuit includes a decoupling capacitance located in a connector that is formed as a socket, or frame for the IC. The power delivery system takes the form of a power reservoir that is integrated into a connector, thereby eliminating the need for complex and expensive power traces to be formed in or discrete capacitors mounted on a circuit board to which the IC is connected. The system includes a connector that takes the form of a cover member that fits over the IC and which contains a recess that accommodates a portion of the IC therein. The cover member includes at least a pair of spaced-apart capacitor plates that are disposed therewithin. Electricity is supplied to the plates so that they will become charged as a capacitor and the plates are formed with a plurality of terminals that extend into contact with the IC so that the plates may selectively discharge to the IC and thereby provide it with operating and surge currents.

Abstract: A connector assembly (10) includes two interengaging plug connector and receptacle connector halves (16,18) with power and circuitry terminals (52,82,38,74) integrated therein. Each of the plug and receptacle connector halves (16,18) include respective dual plug and receptacle housings (60,20) spaced apart from each other in a substantially parallel relationship. The dual connector housings (60,20) of the plug and receptacle connector halves (16,18) are evenly spaced apart by bridging pieces (50,80) which extend between the connector housings to connect them together. The bridging pieces may either be integrally formed with the connector housings (20,60) or they may be separately formed (208) from the connector housings and include engagement members (210,212) which engage the connector housings. The bridging pieces (50,80) have power terminals (52,82) disposed therein so that the connector effects a connection not only between signal circuits of the circuit boards, but also between power circuits.

Abstract: A land grid array connector is formed by attaching a reinforcing member to a frame and coating the reinforcing member with an elastomeric compound to form a reinforced, flexible body portion of the connector. Conductive wires are inserted in pairs in an array in the fabric extent. Free ends of the wires extend past the elastomeric compound to provide contacts of the connector. The pairs of wires provide redundancy for the contacts to ensure a reliable connection.
