  • Publication number: 20240372301
    Abstract: A connector assembly, configured to mate with a mating connector along a mating direction, includes a circuit board, at least one cable, an insulative housing, an electrically conductive unitary shield, a pull tab, and a retention feature. The cable includes a plurality of conductors having front ends terminated at conductive pads of the circuit board. The housing is tightly overmolded around at least a portion of the circuit board. A mating end of the circuit board extends forwardly from a mating face of the housing. The shield includes a top wall extending between a back end and a front end thereof. The pull tab is rotatably attached to the shield near a front end of a top wall of the shield. The retention feature of the shield engages a corresponding retention feature of the mating connector to prevent the connector assembly from unmating from the mating connector.

  • Publication number: 20240250484
    Abstract: An electrical connector configured to mate with a mating connector along a mating direction includes an electrically insulative unitary housing, pluralities of top and bottom contacts, and an electrically conductive unitary shield. The pluralities of top and bottom contacts are disposed in a central slot at a respective top surface and a bottom surface of the central slot for making contact with corresponding conductive terminals of a tongue of the mating connector. The shield is removably assembled to the housing along the mating direction from a rear side of the housing. The shield includes a base shield substantially covering an entire bottom surface of a bottom wall of the housing, and opposing side shields substantially covering opposing side walls of the housing. The shield leaves substantially an entire top surface of a top wall of the housing and the rear side of the housing exposed.

  • Publication number: 20220415752
    Abstract: A direct to chip cooling film for two-phase cooling. The film includes a dielectric layer having a first surface for attachment to a cold plate or circuits and having a second surface. A metal layer is on the second surface of the dielectric layer with a pattern of features on a side opposite the dielectric layer. This surface pattern provides increased surface area and multiple nucleation sites for bubbles formation for two-phase cooling. The features can also include metal nodules to further enhance the nucleation.
