Definitions

  • the present invention relates to the field of electrical connections and more particularly to components mountable to a circuit board.
  • circuit boards are utilized to which are mounted numerous electrical and electronic components.
  • Smaller circuit cards are utilized to establish electrical connections to a larger circuit board in a manner that permits removal and disconnection, by inserting an edge of the card into a receptacle connector mounted on the board and containing an array of contacts connected to circuits of the board; contact sections of the contacts are exposed within a card- receiving cavity of the connector that engage circuit pads on the card surfaces upon card insertion. It has become useful to secure certain cards within larger modules so that components mounted on the card are protected by the module covers during handling.
  • modules need to be accurately guided during mating with the receptacle connector so that the leading end of the enclosed card is accurately received into the card- receiving cavity of the connector, since the module covers inhibit accurate visual alignment of the card with the cavity.
  • elongate guide members projecting from the board from ends of receptacle connectors to facilitate mating in similar situations. Such elongate guide members may be mounted on the circuit board substantially prior to their actual use during module mating.
  • An assembly includes a frame mountable on the circuit board surrounding the receptacle connector or optionally as an integral portion of the connector housing. At opposed ends of the frame are mounted respective guide members containing inwardly facing channels precisely aligned with the card- receiving cavity of the connector.
  • the guide members are pivotably secured to the frame, so that the members may be pivoted to a recumbent orientation parallel to the circuit board when a module is not mated to the connector, and be pivoted to an erect position for use.
  • embossments of a frame end section extend through apertures of tab sections of each guide member to establish the pivotable connection.
  • the tab sections of the guide members include preferably horizontal slots to permit sliding the embossments therealong to become seated in the pivot apertures.
  • the guide member tab sections define the embossments while the end blocks define pivot apertures with preferably horizontal slots permitting insertion of the embossments into the pivot apertures .
  • FIGURE 1 is an isometric view of the present invention with the guide members exploded from the frame;
  • FIGURE 2 is an isometric view of the frame with the guide members assembled thereto and positioned about a connector for module mating therewith;
  • FIGURE 3 is an isometric view of the assembly with the guide members in a retracted position
  • FIGURE 4 is an isometric view of second assembly embodiment of guide members assembled to a frame and positioned about a connector for module mating therewith;
  • FIGURE 5 is an isometric view of the assembly with the guide members in a retracted position;
  • FIGURE 6 illustrates the guide member of FIGS. 4 and 5 exploded from an end block, with board locks and a vibration suppressor exploded from end block;
  • FIGURES 7 and 8 are section views of the guide member of FIGS. 4 to 6 mounted to a frame end section showing the pivot sections thereof, with the guide member lowered and erect, respectively;
  • FIGURE 9 illustrates another embodiment of a guide member of the present invention exploded from an end block.

  • frame 30 and guide members 60,62 are molded of plastic material such as polycarbonate resin.
  • Fasteners 32 are shown to be utilized to secure the guide assembly to the circuit board through the use of bolts (not shown) extending upwardly from the board to be threaded into fasteners 32, which are movably held captive in respective holes
  • integral board fastening sections may be formed that depend from the mounting flanges to extend through mounting holes of the circuit board, that latch beneath the board upon complete insertion therethrough, thereby eliminating the necessity for additional fastening hardware and also simplifying board mounting.
  • Frame 32 includes a connector aperture 40 within which is seated connector 14 disposed between guide members 60,62.
  • Connector 14 may be, for example, a Slot 1 Connector sold by AMP Incorporated, Harrisburg, PA under Part Nos . 145251-1 and -2.
