  • Patent number: 8998656
    Abstract: A terminal fitting (T) includes a rectangular tube (2) into which a mating terminal (M) is to be inserted. A tongue (11) is cantilevered backward in the tube (2). A support (35) struck from the bottom plate (3) to project into the rectangular tube (2) from the bottom plate (3). An auxiliary spring (15) cantilevers forward from the support (35). Opposite widthwise sides of this support (35) are continuous with the bottom plate (3). The base end part of the auxiliary spring (15) is lifted up from the bottom plate (3) by forming the support (35). Thus, the base end part does not project from the bottom plate (3) even if the auxiliary spring (15) is resiliently deformed.

  • Patent number: 8944861
    Abstract: A terminal fitting has a rectangular tube (2) with a ceiling plate (8). A struck portion (19) is formed by striking an extending end edge of the ceiling plate (8) inwardly of the rectangular tube (2) while maintaining a plate thickness. The inner surface of this struck portion (19) is at the same height as the projecting end of a ceiling plate side contact portion (18) and the outer surface of the struck portion (19) is at the same height as the inner surface of the ceiling plate (8) around the contact portion. A pressing portion (9) is bent from the upper end edge of a second side plate (5) to extend substantially parallel to a bottom plate (3) and contacts the outer surface of the struck portion (19). The pressing portion (9) does not project in a height direction from the ceiling plate (8).

  • Patent number: 8905798
    Abstract: A terminal fitting has a tubular connecting portion (11) with includes a base wall (14) in the form of a flat plate. A first spring piece (25) is cantilevered in the connecting portion (11) and is resiliently deformed toward the base wall (14) when a mating tab comes into contact therewith. A second spring piece (31), which is narrower than the first spring piece (25), projects from the base wall (14) and comes into contact with the first spring piece (25) from the side of the base wall (14). Excessive deformation preventing pieces (36) project at opposite widthwise sides of the second spring piece on the base wall (14) and prevent excessive resilient deformation of the first spring piece (25) by coming into contact with a free end portion (27) of the first spring piece (25) from the side of the base wall (14).
