  • Patent number: 11996666
    Abstract: A compression die configured to crimp a composite core is disclosed. The compression die includes an outer body having a tool engaging surface, and an inner body coupled to the outer body. The inner body has a crimping area, wherein the crimping area of the inner body includes ten planar surfaces. The ten planar surfaces are positioned at an angle with respect to an adjacent planar surface such that the combination of the ten planar surfaces form a decagon shaped channel. Crimping is performed by the compression die by inserting the composite core into an encasing connector, which is then inserted into the decagon shaped channel of the compression die. A radial force towards the center of the decagon shaped channel is applied until an outer circumference of the encasing connector containing the composite core fully engages a surface area of each of the ten planar surfaces.

  • Publication number: 20230128519
    Abstract: An electrical connector for high speed signals. The connector has multiple conductive elements that may serve as signal or ground conductors. A member formed with lossy material and conductive compliant members may be inserted in the connector. The conductive compliant members may be aligned with conductive elements of the connector configured as ground conductors. For a connector configured to carry differential signals, the ground conductors may separate pairs of signal conductors. The member may further include a conductive web, embedded within the lossy material, that interconnects the conductive compliant members. For a receptacle connector, the conductive elements may have mating contact portions aligned along opposing surfaces of a cavity. The conductive elements may have contact tails for attachment to a printed circuit board and intermediate portions connecting the mating contact portions and the contact tails. The conductive compliant members may press against the intermediate portions.
