  • Publication number: 20230033076
    Abstract: Terminals have a retained portion located forwardly of a receiving space and retained in a housing, and a contact arm portion that extends toward the rear from the retained portion; a contact arm portion has a contact portion that protrudes toward the receiving space in the connector thickness direction perpendicular to the forward-backward direction and the terminal array direction and is capable of contacting the counterpart connect body; a contact portion faces the interior surface of the receiving space across a gap in the connector thickness direction; the terminals have an extension portion located forwardly of the contact portion; the extension portion has a reflective portion in the rear end portion thereof; the reflective portion has a rear end face within a range that includes the protruding end of the contact portion when viewed from the rear; and the rear end face is formed as a reflecting surface.

  • Patent number: 11201425
    Abstract: A movable member is provided at a flat conductor insertion location on one side in the connector thickness direction; at least either restricting portions or restricted protrusions have oblique surfaces rearwardly sloped toward the other side in the connector thickness direction; upon complete insertion of the flat conductor, engaging portions are positioned to be engageable with engaged portions in the direction of disengagement of the flat conductor at locations rearward of said engaged portions of the flat conductor; and, when a rearward disengagement force acts on the flat conductor upon complete insertion of said flat conductor, the engaged portions of the flat conductor engage the engaging portions and the restricted protrusions abut the restricting portions, as a result of which at least a reaction force directed toward the other side in the connector thickness direction is received from the restricting portions.

  • Patent number: 10868374
    Abstract: An electric connector for a circuit board includes a housing including a reception part, a plurality of metal members, and a movable member that is movable relative to the housing. The movable member includes a movement restricted part. The metal members include a rolled surface that is parallel to a connector width direction and an exposed part that is exposed from the housing. The rolled surface of the exposed part faces the movement restricted part and the exposed part includes a movement restricting part that restricts movement of the movement restricted part. The connector includes a housing part for housing the movement restricted part and the movement restricting part.

  • Patent number: 9871306
    Abstract: An object is to provide an electrical connector for a flat conductor that does not leave behind plastic deformation on a pressing arm part of a terminal pressing a flat conductor. A metal plate terminal, housing, and movable member are provided, where the terminal has a pressing arm part extending such that an insertion-and-removal direction of a flat conductor is in a longitudinal direction, and a supporting arm part extending in the longitudinal direction, which is connected with the pressing arm part by a connecting part. The pressing arm part has a pressing part for pressing one surface of the flat conductor on a rear end side which is an insertion side of the flat conductor, and a pressure receiving part receiving a force from a cam part on a position more forward than the pressing part.
