    Abstract: A board connector includes a housing (10) mounted on a mounting surface (S) of a circuit board (P) and includes a terminal holding portion (11). Two types of long narrow terminal fittings (13, 20) are provided and each includes a board connecting portion (14, 21) extending in a front-rear direction and to be fixed to the mounting surface (S) behind the terminal holding portion (11). Each terminal connecting portion (15, 22) penetrates the terminal holding portion (11) in the front-rear direction. The terminal connecting portions (15, 22) have different heights from the mounting surface (S). The two types of terminal fittings (13, 20) include extra length links (16, 23) longer than heights of the terminal connecting portions (15, 22) from the mounting surface (S) and linking front ends (14F, 21F) of the board connecting portions (14, 21) and rear ends (15R, 22R) of the terminal connecting portions (15, 22).

  • 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.

  • Publication number: 20200044379
    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.
