Definitions

  • the invention disclosed herein relates to card edge connectors for electrically connecting circuits on a printed circuit card to circuits on a printed circuit board or back plane.
  • Known card edge connectors are constructed to receive circuit cards having conductive traces or pads on a given center-line spacing; e.g., 0.050 inches between adjacent pads. Thus, a card having a different spacing could not be accepted therein. This means that if a user wanted to use a new circuit card having a different pad spacing, he would have to remove the first card edge connector (a difficult, time consuming task) and install a second connector which would accept the new card.
  • a dual purpose card edge connector which can receive either one of two different printed circuit cards having conductive pads on different center-line spacing.
  • the connector includes a dielectric housing having a card receiving slot and conductive contact elements disposed therein with contact portions thereon alternatingly projecting into the slot at high and low levels. Further, positioning members are provided in the slot to position one circuit card so that only the contact portions at the high level engage conductive pads thereon and to position a different circuit card so that the contact portions at both levels will engage conductive pads thereon.
  • card edge connector 10 constructed in accordance with the present invention, is capable of receiving either printed circuit card 12, having closely-spaced conductive pads 14; e.g., pads 14 being on 0.050 inch center-line spacing, or card 16 having pads 18 on a less-dense spacing; e.g., 0.100 inches.
  • Connector 10 as more clearly shown in Figure 2, includes an elongated, dielectric housing 20 having a card-edge receiving slot 22 and a plurality of conductive contact elements 24, 26.
  • Contact elements 24, 26 are respectively located in cavities 28, 30 which preferably border both sides of slot 22 and which open thereinto. As shown, cavities 28 alternate with cavities 30.
  • positioning members 34 spaced along floor 32 of slot 22 and extending upwardly therefrom are positioning members 34 (only one is shown in Figure 2). Additionally, transverse keying walls 36 ( Figures 1 and 5) are provided in slot 22 to insure that cards 12 and 16 are inserted thereinto in the proper orientation and registration.
  • cavities 28 include pre-loading bar 38 extending thereacross adjacent the top thereof. Further, passages 40, located near the center of housing 20, extends therethrough, opening into cavities 28 and onto the housing's bottom surface 42. Contacts 24 are positioned in cavities 28 with free ends 44 bearing against bar 38 and leads 46 extending outwardly from surface 42 of housing 20 through passages 40. Further, contact portions 48 on resilient beams 50 project into slot 22 near top surface 52 of housing 20.
  • cavities 30 open only into the lower half of slot 22 with walls 54 closing off access to the upper half.
  • Passages 56, adjacent side walls 58, extend through housing 20, opening into cavities 30 and onto bottom surface 42.
  • Contacts 26 are positioned in cavities 30 with an upper portion 60 on reversely bent resilient beams 62 being preloaded by free ends 64 of walls 54 and contact portions 66 adjacent free ends 68 of beams 62 projecting into the lower half of slot 22; i.e., below walls 54.
  • Leads 70 extend outwardly from surface 42 of housing 20 through passages 56.
  • contact portions 48 on elements 24, alternating with contact portions 66 on elements 26, project into the upper half or upper level of slot 22 while contact portions 66 project into the lower half or lower level of slot 22.
  • Both contact elements 24, 26 are stamped and formed from a suitable conductive material; e.g., beryllium copper or phosphor bronze.
  • Figure 5 shows card 12 positioned above connector 10.
  • Pads 14 include pads 14a which are adjacent card edge 72 and pads 14b which are located interiorly from edge 72. Further spaced notches 74 are provided in edge 72 with the spacing of positioning members 34 in slot 22. Keying notches 76 are provided to cooperate with keying walls 36. As card 12 is inserted into slot 22, notches 74 receive positioning members 34 so that card edge 72 abuts slot floor 32. Accordingly, and as shown in Figure 6, contact portions 48 on elements 24 engage pads 14b and contact portions 66 engage pads 14a adjacent card edge 72; ie., in the lower half of slot 22.
  • Figure 7 shows card 16 positioned above connector 10.
  • Pads 18 are adjacent card edge 78.
  • Keying notches 76 in edge 78 are provided to cooperate with keying walls 36 in slot 22.
  • edge 78 abuts positioning members 34 to position card 16 in the upper half thereof. Accordingly, as shown in Figure 8, only contact portions 48 on contact elements 24 engage pads 18 on card 16.
  • positioning members 34 are shown as transverse walls extending upwardly from slot floor 32.
  • equivalent positioning members can take other forms; e.g., pins crossing slot 22 at the appropriate height.
  • the profile of slot 22 can be tailored to accept different cards of different thicknesses so that, for example, a thin card would go to the floor while a thicker card would be stopped above the floor.
  • a card edge connector which can accept, without modification, printed circuit cards having conductive pads on one center-line spacing or other circuit cards having conductive pads on another center-line spacing.
  • the connector includes conductive contact elements positioned along a card edge-receiving slot and having contact portions thereon projecting into the slot at alternatingly high and low levels. Further, positioning members in the slot cooperate with the cards such that cards having notches along the edge thereof are permitted to slide past the positioning members so that the pads thereon are engaged by the contact portions at both levels. Alternatively, a card without notches are prevented by the positioning members from entering the slot too far so that the conductive pads thereon are engaged only to the upper level contact portions.
