  • Patent number: 10931056
    Abstract: A connector has parts that can be used in common as much as possible in different specifications to reduce cost and to facilitate parts management. In a first specification having a high shielding function, a terminal fitting (20) connected to a shielded electric wire (15) is accommodated in a dielectric (23). The dielectric (23) is surrounded by an outer conductor (40) that is connected to a braided wire (18). The second specification requires no shielding function, and thus the outer conductor (40) is not used. Rather, a sub-housing (70) having the same shape and size as the outer conductor (40) of the first specification is used. The sub-housing (70) is configured to accommodate and retain the terminal fitting (20) and is locked in a same retained state as in the first specification when accommodated in a common housing (10) used in both specifications.
