  • Connector
    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.

  • CONNECTOR
    Publication number: 20190326702
    Abstract: A male internal conductor and a female internal conductor are reliably connected. When female-side and male-side dielectric bodies (16, 41) approach each other in an opposing positional relationship, a tab (32) of a male internal conductor (30) is inserted into a female-side dielectric body (41) and connected to a female internal conductor (42). The female-side dielectric body (41) has an opposing surface (41S) facing the male-side dielectric body (16) and formed with a female-side positioning portion (47). The male-side dielectric body (16) has an opposing surface (22S) facing the female-side dielectric body (41) and formed with a male-side positioning portion (25) which is disposed ahead of the tab (32) and which can be fitted with the female-side positioning portion (47) in a state where the tab (32) is not in contact with the female-side dielectric body (41).

  • CONNECTOR
    Publication number: 20190013614
    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.

    Abstract: An electrical connection device includes a first connector (C1) having a first housing (10), a second connector (C2) having a second housing (20) for receiving the insertion of the first housing (10), and a connection detecting tool (30). The first housing (10) includes a housing body (12), a lock (14) having a tool restraining portion (14d) and a displacement restricting portion (16) for blocking an insertion allowing displacement of the lock (14). The connection detecting tool (30) is held at an operating position to resiliently deform the displacement restricting portion (16) to allow the insertion allowing displacement. The tool restraining portion (14d) restrains the connection detecting tool (30) at the operating position so as not to be separable while allowing the separation of the connection detecting tool (30) from the operating position as the lock (14) resiliently returns to a lock position.
