  • Patent number: 7802994
    Abstract: A combination of connector assembly and two printed circuit boards includes a first printed circuit board defining a guiding gap at one edge thereof and a second printed circuit board, a receptacle connector including a receptacle insulating housing and a plurality of receptacle terminals, a plug connector including a plug insulating housing and a plurality of plug terminals. The receptacle insulating housing defines a plurality of assisting channels penetrating through a bottom surface of the receptacle insulating housing in order to communicate with the guiding gap of the first printed circuit board. Each of the receptacle terminals has a pair of contact portions face-to-face stretching into the corresponding assisting channel. Each of the plug terminals has a contact arm stretching out of the plug insulating housing so as to pass through the guiding gap to be electrically clamped by the contact portions of the corresponding receptacle terminals.

  • Patent number: 7794289
    Abstract: A circuit board connector assembly includes two receptacle connectors each including a receptacle insulating housing and a plurality of receptacle terminals disposed in the receptacle insulating housing, and a plug connector disposed on the top of two adjacent receptacle connectors. Each of the receptacle terminals has a base board. Two opposite side edges of the base board extend towards a same direction to form a pair of clamping portions. The plug connector includes a plug insulating housing and a plurality of plug terminals integrated in the plug insulating housing. Each of the plug terminals has a connecting board molded in the plug insulating housing. Two opposite ends of the connecting board extend towards a same direction to form a pair of contact arms extending beyond a mating surface of the plug insulating housing to be electrically clamped by the corresponding two pairs of clamping portions of the two receptacle connectors.

  • Patent number: 7775827
    Abstract: A flexible printed circuit board connector adapted for receiving a flexible printed circuit board has an insulating housing including two blocking walls, each defines a lateral side having a buckling cavity at a front thereof and a first and second locating cavities at a rear thereof. The buckling cavity includes a first buckling cavity and a second buckling cavity extending frontward from the first buckling cavity. The second locating cavity is located in front of and spaced from the first locating cavity. A cover defines two lateral plates respectively secured to the lateral sides, each has a locating portion and a buckling portion respectively protruded inwards from an inner side thereof. The locating portion is capable of being pivotally mounted in the first locating cavity, and then the locating portion and the buckling portion can be moved frontward to the second locating cavity and the second buckling cavity, respectively.

  • Patent number: 7771227
    Abstract: A circuit board connector assembly adapted for connecting two printed circuit boards includes a receptacle connector having a receptacle insulating housing and two plug connectors each connected with the corresponding printed circuit boards and having a plug insulating housing. Two opposite ends of the plug insulating housing respectively define a holding cavity passing through a side surface thereof. The holding cavity is connected with the side surface by a slope. Two opposite ends of the receptacle insulating housing extend downward to respectively form two connecting arms spaced from each other. A free end of each of the connecting arms is bent inward to form a buckling portion. The printed circuit boards are electrically connected with each other by means of the plug connectors inserted into the receptacle connector. The buckling portions can be buckled into and slide out from the corresponding holding cavities along the corresponding slopes.
