Patent number: 7298628Abstract: 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.Type: GrantFiled: June 27, 2006Date of Patent: November 20, 2007Assignee: Molex IncorporatedInventors: Augusto P. Panella, John E. Lopata, James L. McGrath, Arindum Dutta

Patent number: 7160154Abstract: Termination assemblies for terminating high-frequency data signal transmission lines include housings with one or more cavities that receive ends of the transmission line therein. The transmission line typically includes a dielectric body and a plurality of conductive elements disposed thereon, with the plurality of conductive elements being arranged in pairs for differential signal transmission. The termination assemblies, in one embodiment include hollow end caps that are formed from a dielectric and which have one or more conductive contacts or plated surfaces disposed on or within the cavity so that they will frictionally mate with the conductive traces on the transmission line. In another embodiment, a connector housing is provided with a center slot and a plurality of dual loop contacts to provide redundant circuit paths and low inductance to the termination assembly. A coupling element may be utilized in the slot to achieve a desired level of coupling between the termination contacts.Type: GrantFiled: July 15, 2005Date of Patent: January 9, 2007Assignee: Molex IncorporatedInventors: David L.

Patent number: 6936917Abstract: 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.Type: GrantFiled: September 25, 2002Date of Patent: August 30, 2005Assignee: Molex IncorporatedInventors: John E.

Publication number: 20040198082Abstract: A method of forming an electrical connector is provided. A mask having recesses is provided and solder is dispensed into the recesses. Contact tails from terminals in a connector are positioned below the mask and aligned with the recesses of the mask such that the contact tails either abut against the solder or are in close proximity thereto. As the solder is heated, it melts and flows onto the contact tails and forms masses of solder on the contact tails. The masses of solder are then allowed to cool and harden on the contact tails and the mask is removed. An electrical connector with the masses of solder connected thereto is thus provided.Type: ApplicationFiled: April 7, 2003Publication date: October 7, 2004Inventors: Victor Zaderej, Arindum Dutta, John E.

Publication number: 20040092143Abstract: A termination structure for mating a cable connector to a circuit board includes a plurality of associated sets of terminals, each terminal set including a pair of differential signal terminals and a ground reference terminal. Each associated set of terminals is arranged in triangular pattern through the connector in order to reduce the impedance through the connector, and adjacent associated terminal sets are inverted so that the ground reference terminals of alternating associated terminal sets are located along one row of the connector along with signal terminals of intervening terminal sets, while the ground reference terminals of intervening terminal sets are located along a second row of the connector, along with the signal terminals of alternating associated terminal sets. This inverted arrangement increases the density of the connector.Type: ApplicationFiled: December 22, 2003Publication date: May 13, 2004Inventors: Galen Fromm, David L. Brunker, Daniel L.
