Patent number: 11901663Abstract: An electrical connector with improved high frequency performance. The connector has conductive elements, forming both signal and ground conductors, that have multiple points of contact distributed along an elongated dimension. The ground conductors may be formed with multiple beams of different length. The signal conductors may be formed with multiple contact regions on a single beam, with different characteristics. Signal conductors may have beams that are jogged to provide both a desired impedance and mating contact pitch. Additionally, electromagnetic radiation, inside and/or outside the connector, may be shaped with an insert electrically connecting multiple ground structures and/or a contact feature coupling ground conductors to a stiffener. The conductive elements in different columns may be shaped differently to reduce crosstalk.Type: GrantFiled: December 5, 2022Date of Patent: February 13, 2024Assignee: Amphenol CorporationInventor: Thomas S. Cohen

Patent number: 11901660Abstract: A broadside coupled connector assembly has two sets of conductors, each separate planes. By providing the same path lengths, there is no skew between the conductors of the differential pair and the impedance of those conductors is identical. The conductor sets are formed by embedding the first set of conductors in an insulated housing having a top surface with channels. The second set of conductors is placed within the channels so that no air gaps form between the two sets of conductors. A second insulated housing is filled over the second set of conductors and into the channels to form a completed wafer. The ends of the conductors are received in a blade housing. Differential and ground pairs of blades have one end that extends through the bottom of the housing having a small footprint. An opposite end of the pairs of blades diverge to connect with the wafers.Type: GrantFiled: February 17, 2021Date of Patent: February 13, 2024Assignee: Amphenol CorporationInventors: Thomas S. Cohen, Huilin Ren, Marc B. Cartier, Jr., Trent K. Do, Mark W. Gailus

Patent number: 10096945Abstract: An electrical connector designed for high speed signals. The connector includes one or more features that, when used alone or in combination, extend performance to higher speeds. These features may include compensation for tie bars that are used to hold conductive members in place for molding a housing around the conductive members. Removal of the tie bars during manufacture of the connector may leave artifacts in the conductive members and/or housing, which may be addressed by the features. The conductive members, for example, may include regions, adjacent tie bar locations, that compensate for portions of the tie bar that are not fully removed. Alternatively or additionally, a housing may include openings around tie bar locations such that a punch may be used to sever the tie bars. These openings may be filled to avoid performance-affecting artifacts.Type: GrantFiled: December 12, 2016Date of Patent: October 9, 2018Assignee: Amphenol CorporationInventors: Marc B.
