CABLE CONDUCTOR FITTING

摘要

Various embodiments concern a lead comprising a cable conductor and a coil electrode having one or more filars, the one or more filars wound in a helical pattern. The lead can further include an inner fitting axially aligned with the coil electrode. The inner fitting can comprise external threading and a slot extending along the inner fitting. The slot can receive a portion of the cable conductor. The lead can include an outer tubular fitting having a lumen with internal threading. Each of the coil electrode and the inner fitting can be partially received within the lumen, both of the external threading and the one or more filars threadedly engaged with the internal threading. The cable conductor can be pinched in the slot to mechanically connect the cable conductor to the inner fitting. The pinching can be supported by the outer tubular fitting.
