  • Patent number: 8523580
    Abstract: An electrical connector includes a housing and a plurality of terminals disposed in the housing. The housing includes a bottom wall and a protruding wall. The terminal includes a held portion for being held in the housing, a base portion, a transition portion, an elastic arm portion and a contact portion. The protruding wall includes a plurality of vertical wall portions and a displacement receiving recess. The housing has an opening penetrating the bottom wall at least at a lower side of the displacement receiving recess. The displacement receiving recess communicates with the opening. Further, the base portion and the transition portion of the terminal are situated outside of the displacement receiving recess.

  • Patent number: 8182272
    Abstract: An electrical connector includes a housing to be disposed on a circuit board, a receiving recess portion formed in the housing for receiving a mating connector, and a terminal arranged in the housing. The terminal includes a U-shape portion, an extending portion extending outside the receiving recess portion a first sidewall facing outside, and a connecting portion. The U-shape portion includes a first arm portion and a second arm portion. The first arm portion is fitted along the sidewall and the second arm portion is fitted along a second sidewall. The first arm portion and the second arm portion include locking portions for being fixed against an inner surface of the receiving recess portion, respectively. The extending portion is arranged to be away from the first sidewall to form a space in between.

  • Patent number: 7748993
    Abstract: A connector to be connected to a mating connector includes a housing having a receptacle recess portion for receiving the mating connector, and a terminal retained in the housing. The housing includes a containing groove extending in a connecting direction for containing a fitting portion of the terminal. The fitting portion of the terminal includes an engaging portion at a side end edge thereof. The containing groove includes a regulating wall portion extending in the connecting direction and located inner side than a position of an edge surface of the engaging portion at the containing groove. The regulating wall portion includes a regulating surface extending in the connecting direction and a width direction of the terminal. When the mating connector is extracted, the regulating surface regulates an elastic deformation of the fitting portion by abutting against and engaging with the engaging portion.
