  • Patent number: 7361066
    Abstract: A male terminal fitting (1) is formed by bending a flat metal plate worked into a specified shape and includes a contact (2), a rectangular tube (4) formed to be wider than the contact (2), and a link (3) between the contact (2) and the rectangular tube (4). The link (3) is not connected with the front edge of the upper surface of the rectangular tube (4) over the entire width. Thus, bending resistance against an external force can be improved by increasing deflectability while holding down bending rigidity.

  • Patent number: 7252557
    Abstract: A female connector (F) has a housing (10) with a front end and cavities (11) extend to the front end. Terminal fittings (40) are mounted in the cavities (11). A front wall (50) is mounted on the front end of the housing (10) and is formed with tab insertion holes (51) that can communicate with cavities (11). An operable surface (59A) is exposed at an end surface of the front wall (50). The front wall (50) can be moved from a full locking position to a partial locking position along the front end of the housing (10) by pushing this operable surface (59A). Portions of the end surface of the front wall (50) other than the operable surface (59A) are covered at least partly by an wall (26) of the housing (10) to limit movement of the front wall (50).

  • Patent number: 7252561
    Abstract: A terminal fitting (T) has a rectangular tube (10) with a side plate (13R) and a receiving plate (35) that extends inwardly in a width direction from the front edge of the side plate (13R). A probe (P) can be brought into contact with this receiving plate (35). Thus, a contact area of the probe (P) along the width direction is wider than the thickness of the right side plate (13R). Thus, the probe (P) can be brought securely into contact with the rectangular tube (10) even if displaced along the width direction.

  • Patent number: 7238064
    Abstract: A male terminal fitting (1) has a rectangular tube (4). A cut is made in wall of the rectangular tube (4) to form a stabilizer (20) and produces a cut hole (22). An end edge of a closing plate (21) is arranged to face the cut hole (22) and a closing piece (23) is formed at a rear-end opening of the rectangular tube (4). The closing plate (21) and the covering piece (23) substantially prevent external matter or a leading end of another male terminal fitting (1) from intruding into the rectangular tube (4).

  • Patent number: 7229314
    Abstract: A male terminal fitting (1) has a rectangular tube (4). A locking edge (15) engageable with a locking portion provided in a cavity is formed over the entire width in an outer surface of a rectangular tube (4). No opening is formed in the outer surface of the rectangular tube portion (4) by forming this locking edge (15). Closing pieces (12) are provided at positions slightly retracted inwardly of the locking edge (15). Thus, problems such as the intrusion of external matter from the outside and the deformation of a leading end portion of another male terminal fitting (1) due to the entrance into the rectangular tube (4) can be avoided.
