Resiliently Biased Contact Patents (Class 439/295)
  • Patent number: 6676426
    Abstract: An electrical connector is positioned in a biased manner relative to a receptacle upon mating. The mated electrical connector is positioned along a first positioning axis of the receptacle in predetermined electrical contact with a target circuit. The connector includes a housing that mates with the receptacle along a mating axis and is placed at a predetermined position along an orthogonal first positioning axis. The housing also defines a first-positioning-axis datum which engages the receptacle. Furthermore, the connector includes an electrically conductive contact structure mounted on the housing, and a biasing mechanism operatively coupled with the housing. The biasing mechanism acts to maintain the first-positioning-axis datum in abutment with the receptacle upon mating of the housing with the receptacle.

  • Patent number: 5127839
    Abstract: An electrical connector assembly has terminals which have first resilient legs and second rigid legs. The second rigid legs cooperate with the housing to secure the terminals therein. The entire length of the first resilient leg is utilized as a resilient beam. The first and second legs also provide two parallel paths over which signals can travel. The configuration of the terminals minimize the height of the assembly and provides a reliable electrical connection over which high speed signals can travel.

  • Patent number: 5106320
    Abstract: A connector having an electrically insulative housing with at least one terminal receiving cavity extending longitudinally through the housing between the forward and rearward ends thereof. The forward end of the housing is structured to releasably mate with a similarly shaped housing of a second connector that is inverted relative to the first. The rearward end of the housing is structured so that each terminal receiving cavity longitudinally receives a terminal, the terminal having an attached electrical cable extending beyond the rearward end of the housing. A biasing spring in the form of a cantilever, biases the terminal transversely between the floor of the terminal receiving cavity and the terminal. A latch edge of the biasing spring interferingly engages the terminal so as to affix the terminal within the terminal receiving cavity.

  • Patent number: 4971565
    Abstract: First and second connector members extend in one direction, for example, horizontally, and include pairs of left and right hand non-conducting tenons projecting transversely from each member in another direction, e.g., vertically. Each pair of tenons forms a channel for receiving a tenon of the other member when the connection is made. Each left hand tenon carries a conductor strip which includes a resilient contact surface within the channel formed by the tenon pair, and each right hand tenon carries a right hand conductor strip including a resilient contact surface outside the channel formed by the tenon pair. Each left hand resilient contact surface is adapted to mate with a right hand resilient contact surface when the members are engaged, thereby effectuating two electrical connections between the engaged pair of tenons. Each conductor strip extends, e.g.
