Definitions

  • an L-shaped edge connector for the use with circuit modules such as printed circuit boards.
  • the inner L-shaped surface of the connector is formed with a slotted channel adapted to receive the leading edge of the board in its base portion.
  • the base of the connector is further fitted with spring contacts for securing and making electrical contact with the leading edge of the board.
  • the slotted channel within the upright portion of the connector is adapted to receive an adjacent edge of the board and provide lateral support thereto.
  • edge connectors for use with circuit modules, such as printed circuit boards, is well known to those skilled in the electronic art. They provide the capability of rapid replacement thereby enhancing the 'serviceability and utility of the particular equipment of which the module is a part.
  • One type of edge connector whichhas enjoyed a successful degree of acceptance has a-plurality of electrical spring contacts arranged in linear fashion at predetermined intervals. These contacts are adapted to receive the leading edge of a circuit board inserted therein and to register with the conductive circuit paths upon the board which emanate therefrom.
  • the connector is generally formed with a slotted channel, having closed ends, into which the contacts are fitted. The leading edge of the circuit board is maintained at a length which will enter the enclosed channel with' a minimum amount of clearance, thereby providing indexing with the contacts.
  • the practice has developed of shaping the leading edge of the board with a projecting tongue which is maintained at a width compatible with the standard widths of connector channels.
  • This practice has proven to result in numerable drawbacks.
  • the shape of the card by virtue of having a projecting tongue, does not provide for the most economical use of card material.
  • the card must be provided with some means of support since the depth of the connector channel is not sufficient to support the cantilevered mass of the card.
  • This invention relates to edge connectors for use with circuit boards and, more particularly, to an L-shaped edge connector defined by a base member and a side member, the base member formed with a slotted channelfor receiving a portion of the leading edge of the circuitboard, the side member providing lateral support to the board via an edge of the board adjacent said leading edge.
  • an object of the present invention to provide an edge connector which is adapted for use with circuit boards of varying width.
  • a further object is to provide an edge connector for use with printed circuit boards of varying width which in addition provides lateral support to the board.
  • Another object of the present invention is to provide an edge connection termination for circuit boards of varying connection edge widths, while at the same time providing indexing, lateral support, and card retention.
  • FIG. 1 is a perspective view of a circuit board assembly in accordance with the present invention
  • FIG. 2 is a partial perspective view taken along section 2- of FIG. I;
  • FIG. 3 is illustrative of a circuit assembly secured to a supporting structure; and v FIGS. 4 and 5 are sectional views of edge connectors in ac- 'cordance with the present invention, adapted for use with single-sided and double-sided circuit boards respectively.
  • FIG. 1 which is illustrative of a circuit board assembly in accordance with the present invention, comprises a circuit board 10 formed with printed circuitry 11 and having circuit elements 12 mounted thereon.
  • the printed circuitry 11 is formed by any of the conventional techniques well-known to those skilled in the art and is configured so as to terminate at the outer portions of the leading edge 13 of the circuit board 10.
  • two L-shaped connectors 15 are provided and disposed so as to be adapted to receive the circuit board 10.
  • the connectors 15 are formed of a dielectric material and are defined by a base portion 16 and a side portion 17.
  • the inner L-shaped surface-of the connectors are formed with a slotted channel 18 open at either end 19 thereof.
  • the leading edge 13 of the circuit board 10 is received by the slotted channel 18 within the base portion 16 of the connector 15 while the slotted channel 18 within the side portion 17 provides lateral support to the circuit board 10 via the edges 20 of the board adjacent said leading edge 13.
  • the side portions 17 of the connectors 15 are formed with detent means 21 adapted to mate with corresponding detent means situated upon the circuit boardlfl, FIG.
  • the detent means 21 as a projection into the slotted channel 18 within the side portion 17 of the connector.
  • the circuit board would be formed with a corresponding notch (not shown) such that the two would mate when the board and connector were properly aligned.
  • the projection may be provided upon the circuit board and thenotch within the connector.
  • a single detent means positioned at the top of the connector has been illustrated, the number or position of such means is not controlling.
  • each of the connector elements 15 is formed with fastening means 22 adaptedto releasably engage cor responding means 23 formed within the supporting structure 24.
  • the releasably engageable fingers 22 are formedas an integral part of the base portion of the connector 15.
  • FIG. 3 depicts the manner in whichthe fingers 22 engage the supporting structure 24.
  • FIGS. 4 and 5 illustrate sectional views of edge connectors adapted for use with either single orldouble sided circuit boards.
  • the base portions 16 of the connectors are fitted with a plurality of electrical spring contacts 25 arranged in linear fashion at predetermined intervals within the slotted channel 18.
  • the base portion of the connector is formed with a series of holes 26 adapted to receive these contacts 25 and to permit the lower portions 27 thereof to project beneath the connector.
  • the supporting structure 24 is provided with a like series of holes 28 adapted to receive these protruding portions 27 of the electrical contacts.
  • These protruding portions thereafter serve as rigid posts to which wire terminals maybe secured, as by wire wrapping, and further provide a means by which connection may be made to circuit paths 29 formed upon the supporting structure.
  • FIG. 3 is illustrative of the latter where the assembly has been passed through a solder wave and solder connections 30 established between the protruding contacts and the conductive circuit paths 29 formedon the underside of the supporting structure 24.
  • the leading edge 13 of the circuit board 10 is inserted into the base portions 16 of the connectors. 15 with the terminating portions of the printed circuit paths 11 being engaged by, and making electrical contact with, the springcontacts 25.
  • the contacts 25 must be arranged so as to. provide proper registration with the terminating circuit paths 11 at the leading edge 13 of the circuit board 10. Accordingly, it may contain contacts 25 on only one side of the slotted channel 18, as in the case of fFlG. 4, or it may be fitted with contacts 25 on both sides of the channel 18, as in FIGS, so as to accommodate a circuit board having conductive paths 11 on both sides thereof. 7
