Description

Cable braid positioning clamp Technical Field The invention relates to a cable braid positioning clamp. In particular, the present invention relates to a clip that cooperates with the braid of a cable to maintain the braid in relation to the signal conductor. Background There are many electrical and mechanical considerations in terminating a high-speed cable (e.g., an RF cable, i.e., a radio frequency cable) to a connector. A typical high-speed cable consists of an outer jacket, braid (for ground reference), foil, dielectric, and inner signal conductors. Connecting the braid for the ground reference is always a challenge for mechanical and electrical performance. Not only is the mechanical connection difficult, but there are also sometimes problems trying to maintain electrical performance through the braid crimp zone. The crimping process typically involves the use of mechanical components, such as ferrules. When the ferrule is crimped over the braid, foil and inner connector, there is a transition zone at the connector termination. In this region, the braid and foil may "bunch up", resulting in degradation of electrical performance. The problem to be solved is to provide a device or clip that eliminates "bunching" of the foil and braid, thereby maintaining the proper relationship of the braid to the signal conductor to minimize degradation of the electrical performance of the cable. Disclosure of Invention This problem is solved by a cable assembly for terminating an end of a cable, the cable assembly comprising a ferrule fixed to a cable jacket at the end of the cable. The housing has an internal connector, wherein a portion of the internal connector is positioned in the ferrule. The inner housing is positioned in the inner connector. The inner housing mates with a separate signal conductor extending from the cable end. The cable has individual signal conductors extending from the end of the cable to the inner housing. The cable also has a braided shield extending from an end of the cable to a portion of the inner connector positioned in the ferrule. The transition zone is disposed between the end of the cable and the end of the portion of the inner connector positioned in the ferrule. The braid locating clip engages the braided shield in the transition region to maintain the braided shield in relation to the signal conductor to minimize degradation of the electrical performance of the cable.
