  • 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: 7223135
    Abstract: A terminal fitting has a rectangular tube (10) formed with a locking hole (19). A resilient contact piece (25) is in the rectangular tube (10) for contacting a tab of a mating terminal fitting. Displacement restricting portions (15F, 15R, 18F, 18R) are provided in the rectangular tube (10) at positions before and behind the locking hole (19) for contacting lateral edges of the resilient contact piece (25) and restricting displacement of a resilient contact piece (25) towards a tab entrance space (32). Thus, external matter that may intrude through the locking hole (19) can not cause a damaging deformation of the resilient contact piece (25).

  • Patent number: 7179138
    Abstract: A terminal fitting (T) has a rectangular tube (10) with a base plate (12) and first and second side plates (13L, 13R) that extend from opposite sides of the base plate (12). A ceiling plate (14) extends from the first side plate (13L) towards the second side plate (13R), and a recess (37) is formed at an extending edge of the ceiling plate (14). A pressing portion (38) extends from the second side plate (13R) and is accommodated in the recess (37) for preventing upward displacement of the ceiling plate (14). Thus, there is no significant step between the upper surfaces of the ceiling plate (14) and the pressing portion (38) and the height of the rectangular tube (10) can be reduced.
