| 20080207057 | MICROPHONE CONNECTOR AND METHOD OF SHIELDING THE SAME - A microphone connector and a method of shielding the same, the microphone connector including a crimping sleeve that covers component members inside a connector portion, the microphone connector being capable of connecting the crimping sleeve and a connector housing electrically. The microphone connector includes a crimping sleeve having a small-diameter cylindrical part and a large-diameter cylindrical part. A microphone cable has a fold-back part folded back so that a shield outer jacket covers an insulating coating. The small-diameter cylindrical part of the crimping sleeve is fitted around an outer side of the fold-back part of the shield outer jacket and is compressed to be coupled with the microphone cable. The large-diameter cylindrical part of the crimping sleeve is put on a connection portion between the cable side connector and the microphone cable. The large-diameter cylindrical part of the crimping sleeve and a connector housing engage each other via a sleeve. | 08-28-2008 |
