  • Patent number: 7674972
    Abstract: A braided shield includes a housing formed from a plurality of wires braided together and having a dual-layer configuration. The housing has an outer layer integrally formed with an inner layer. A support is at least partially disposed in the housing, and the inner layer is disposed between the support and the outer layer. The inner layer and outer layer reduce electromagnetic radiation leakage into/out of the housing by reducing the number of holes in the housing. Forming the braided shield includes providing the housing, which defines a longitudinal axis and a passage extending along the longitudinal axis. The housing has an end portion, and the end portion is compressed transverse to the longitudinal axis. The end portion is then forced into the passage. Accordingly, the braid shield reduces or eliminates electromagnetic radiation while providing a strong and consistent crimp with the support.

  • Patent number: 7422480
    Abstract: A shielded electric cable assembly comprises a shielded electric cable and a shielded electric connector that has an inner terminal, an insulator and an outer shielding terminal. The inner terminal has an attachment portion that is supported on a projecting anvil of the insulator that is disposed in an intermediate bay of the outer shielding terminal. The bay has an opening for a crimp tool that crimps the attachment portion of the inner terminal onto an exposed end of a conductive core of the shielded electric cable. The intermediate bay is closed by side wall flaps of the intermediate bay or by a closure shell. The crimp tool that may be part of the insulator.
