Press-fit terminal and terminal press-fit structure
View Patent ↗To provide a press-fit terminal and a terminal press-fit structure that enable shortening of a press-fit portion in its longitudinal direction and miniaturization of a connector. A press-fit terminal has insertion stoppers that are projectingly provided on respective flanks of a press-fit portion and that have respective engagement surfaces oriented orthogonally to a press-fit direction; and holding projections that are projectingly provided on respective protruding leading-end faces of the insertion stoppers and that bite into interior side walls of a press-fit hole of a housing which receives the press-fit portion. Each of the holding projections is projectingly formed in a portion of the protruding leading-end face of the insertion stopper along its thicknesswise direction.
1. A press-fit terminal comprising:
insertion stoppers that are projectingly formed on respective flanks of a press-fit portion of a terminal body and that respectively have engagement surfaces oriented orthogonally to a press-fit direction; and
holding projections that are provided on associated protruding leading-end faces of the associated insertion stoppers and that bite into an interior wall of a housing which receives the press-fit portion, wherein
each of the holding projections is provided projectingly in a direction perpendicular to a thickness direction of the terminal body or the holding projection in only a portion of the associated protruding leading-end faces in the thickness direction of the terminal body such that a thickness of the each of the holding projections in the thickness direction is smaller than a thickness of the associated leading-end faces in the thickness direction.
2. The press-fit terminal according to claim 1 , further comprising holding surfaces provided in each portion of the protruding leading-end faces which are free of the holding projections.
3. A terminal press-fit structure comprising:
insertion stoppers that are projectingly formed on respective flanks of a press-fit portion of a terminal body and that respectively have engagement surfaces oriented orthogonally to a press-fit direction; and
holding projections that are provided on associated protruding leading-end faces of the associated insertion stoppers and that bite into an interior wall of a housing which receives the press-fit portion, wherein
each of the holding projections is provided projectingly in a direction perpendicular to a thickness direction of the terminal body or the holding projection in only a portion of the associated protruding leading-end faces in the thickness direction of the terminal body such that a thickness of the each of the holding projections in the thickness direction is smaller than a thickness of the associated leading-end faces in the thickness direction; and
tapered walls are formed on the press-fit hole of the housing in a press-fit direction in which the tapered walls come into contact with the respective engagement surfaces of the insertion stoppers.
4. The terminal press-fit structure according to claim 3 , further comprising holding surfaces provided in each portion of the protruding leading-end faces which are free of the holding projections.
