Flexible cable grounding scheme
摘要:
A method for electromagnetically shielding the end of a rigid cable (10) containing a large number of conductors to provide increased bending flexibility is disclosed along with a ground strap assembly (24). Ground strap assembly (24) is designed to shield a cable (10) that consists of a plurality of insulated conductors (18) surrounded by one or more conducting shields (14) (16) and outer insulating sheath (12). A portion of the outer insulating sheath (12) is removed to expose a protruding portion of conducting shield (14). The protruding portion of conducting shield (14) is folded back along a remaining portion of outer insulating sheath (12) thereby exposing the ends of the conductors. Ground strap assembly (24) comprises a braided conducting ground strap (26) that has a cable end portion (32) extending to a central portion (34). Central portion (34) extends to grounding portion (36). The cable end portion (32) is coupled to the protruding portion of the conducting shield (14) of cable (10) that has been folded back. Such coupling shields a portion of the exposed ends of the conductors (18). The central portion (34) of ground strap (26) has an exit opening to allow the exposed conductors (18) to exit from the ground strap (26) thereby allowing the conductors (18) to be flexibly maneuvered and attached to one or more connection points in an electronic device. A ground strap terminal (28) is coupled to the grounding portion (36) of ground strap (26) allowing the ground strap (26) to be attached to ground, thereby shielding the end of the cable from electromagnetic interference.
