  • Patent number: 10734748
    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).

  • Patent number: 10622747
    Abstract: A connector includes a housing (10) having a terminal accommodation chamber (11) formed therein, and a first terminal fitting (12) can be inserted into the terminal accommodation chamber (11). A retainer (20) can be assembled to the housing (10) at a temporary locking position and at a final locking position, and a terminal holding member (30) can be assembled to the housing (10). A second terminal fitting (40) is attached to the terminal holding member (30). Interference parts (24, 26) are formed in the retainer (20) and the terminal holding member (30), respectively. The interference parts do not interfere with each other when the retainer (20) is in the final locking position. However, the interference parts interfere with each other to prevent the terminal holding member (30) from being assembled to the housing (10) when the retainer (20) is in the temporary locking position.

  • Publication number: 20200059033
    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: 10559923
    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.

  • Patent number: 10530069
    Abstract: It is aimed to realize miniaturization. A power distribution device (Da) is for supplying power to a plurality of loads (L) and includes an input-side conductive path (10) to be connected to a battery (B) (power supply), a plurality of terminal holders (13) each including an input-side terminal fitting (20) connectable to the input-side conductive path (10), and a plurality of output-side conductive paths (37) configured to connect the input-side terminal fittings (20) and the loads (L). Since the number of the terminal holders (13) to be connected to the input-side conductive path (10) is a minimum necessary number corresponding to the number of the loads (L), miniaturization is possible.

  • 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.
