Abstract
A connector holder has a U-shaped frame and supports an internal connector-receiving part within the U-shaped frame. Guide pieces are provided that grip the ends of a connector and the cable to which the connector is attached. The connector-receiving part thereby floats inside of the U-shaped frame so as to be positioned accurately for mounting to an opposing connector.
