  • Patent number: 10490928
    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.

  • Patent number: 10476193
    Abstract: It is aimed to detect a mounted state of a second terminal fitting in a terminal unit in which the second terminal fitting is mounted in a terminal holding member. A connector includes an interfering projection (25) formed on a retainer (21). When a second terminal fitting (50) of a terminal unit (30) is properly mounted in a terminal holding member (31), the retainer (21) is displaceable from a partial locking position to a full locking position without the interfering projection (25) interfering with the second terminal fitting (50). When the second terminal fitting (50) is improperly mounted in the terminal holding member (31), the interfering projection (25) interferes with the second terminal fitting (50), thereby restricting a displacement of the retainer (21) to a full locking position.
