20090011642 | SHORT LENGTH COMPLIANT PIN, PARTICULARLY SUITABLE WITH BACKPLANE CONNECTORS - An electrical connector having a plurality of connector units each having a pair of columns of edge coupled differential signal pairs separated by a ground shield terminal. The ground shield terminals each face a different signal pair of terminals in an adjacent column. Notwithstanding the different size and configurations of the ground and signal terminals, the terminals have mounting tail portions that are disposed in a uniform array different from the arrangement of the body portions of the terminals of the connector unit. The mounting tail portions are of a reduced length which benefit the electrical performance of the connector where it meets its supporting circuit board. | 01-08-2009 |
20090011643 | Impedance control in connector mounting areas - A high speed connector with reduced crosstalk utilizes individual connector support frames that are assembled together to form a block of connector units. Each such unit supports a column of conductive terminals in two spaced-apart columns. The columns have differential signal terminal pairs separated from each other by larger intervening ground shields that serve as ground terminals. The ground shields are arranged in alternating fashion within the pair of columns and they are closely spaced together so as to face a differential signal terminal pair. In areas where the terminals are mounted to the connector units, window-like openings are formed in the large ground shield terminals to reduce the amount of broadside coupling between the differential signal terminal pair and the signal terminal pair are narrowed to increase their edge-to-edge distance to account for the change in dielectric constant of the connector unit material filing in the area between the signal terminal pair. | 01-08-2009 |
20090011644 | High speed connector with spoked mounting frame - A high speed connector with reduced crosstalk utilizes individual connector support frames that are assembled together to form a block of connector units. Each such unit supports a column of conductive terminals in two spaced-apart columns. The columns have differential signal terminal pairs separated from each other by larger intervening ground shields that serve as ground terminals. The ground shields are arranged in alternating fashion within the pair of columns and they are closely spaced together so as to face a differential signal terminal pair. The support frames support the ground and signal terminals utilizing radial spokes in which the spokes take the form of ribs that extend along the inner surfaces of one of the connector halves and define V-shaped air channels. | 01-08-2009 |
20090011645 | Mezzanine-style connector with serpentine ground structure - A high speed connector with reduced crosstalk utilizes individual connector support frames that are assembled together to form a block of connector units in a vertical arrangement. Each such unit supports an array of conductive terminals that are arranged in two spaced-apart rows. The rows have differential signal terminal pairs separated from each other by larger intervening ground shields that serve as ground terminals. The ground shields are arranged in alternating fashion within each row of terminals and they are closely spaced together so as to define within the rows of each connector unit, a horizontal serpentine pattern of ground shields that cooperate to act as a single “pseudo” shield within each pair of terminal rows. | 01-08-2009 |
20090011655 | Backplane connector with improved pin header - A backplane electrical connector having a pin header that includes a one-piece housing supporting a plurality of columns of edge coupled differential signal pairs of contacts each separated by a ground contact. The pin header housing base is formed with a plurality of air passageways extending through the base, including an air passageway disposed between each signal contact in one column and an immediately adjacent signal contact in an adjacent column for electrically isolating the adjacent signal contacts from each other by an air dielectric medium. Core-outs which extend only partially through the housing base are provided between each signal contact and an adjacent ground contact in an adjacent column for further isolating differential signal pairs. | 01-08-2009 |
20090011664 | Connector with bifurcated contact arms - A backplane electrical connector electrically and physically connects a daughter card printed circuit board to a backplane printed circuit board. The electrical connect can be of a two-piece construction including a daughtercard connector mateable with a pin header. The daughtercard connector can be assembled from a plurality of wafers which each can include a plurality of conductive leads. The wafers can have an attachment edge that lies adjacent to the daughtercard and a mating edge that is directed toward the pin header. Each conductive lead can include a bifurcated contact extending from the mating edge and each can have a first arm and a second arm. The first and second arms can provide two redundant points of contact with a corresponding conductive pin disposed in the pin header. | 01-08-2009 |

20140273551 | CABLE MODULE CONNECTOR ASSEMBLY SUITABLE FOR USE IN BLIND-MATE APPLICATIONS - A cable module that utilizes a plurality of multi-wire cables to provide connections between two sets of connectors is disclosed. The module has a first set of connectors intended to mate with mating connectors disposed on a mother board and a second set of connectors intended to mate with a plurality of opposing connectors disposed on a plurality of daughter boards. The mother board generally lies in the same plane as the base of the module, while the daughter boards are oriented generally transverse to the module base. The two sets of connectors are capable of limited movement in the horizontal and vertical directions to give the module assembly blind mate functionality. The second set of connectors is restricted from movement in the depth direction, while the first set of connectors is capable of such movement. An exterior actuating mechanism provides a mechanical advantage that reduces the effort required to advance the first set of connectors into mating engagement with their opposing counterparts on the mother board. | 09-18-2014 |
