Definitions

  • a wide variety of electronic devices are made with printed circuit cards mounted in card positions where different cards may be mounted in any particular card position depending on how someone has decided to configure the particular device.
  • One common example of such devices are the so-called personal computers which have several expansion card slots where the owner may install a variety of optional cards such as memory expansion cards, card mounted disc drives, communication interface cards, and the like.
  • a problem may be encountered, particularly by service personnel, in recognizing particular cards installed in such devices when it is necessary to identify a particular card or to understand the manner in which the device has been configured.
  • the components of the card are generally so obscured by adjacent cards that it is difficult to recognize a card from the edge, and service personnel who see many similar devices and who did not configure the particular device cannot identify a card without removing it.
  • an identification system for printed circuit cards in which a label identifying the printed circuit card is mounted along the edge of the card' in a plane perpendicular to the card where it is visible without removing the card from an array of parallel cards.
  • the label extends laterally from the card a distance which does not exceed the maximum projection of components from the card, that is, the maximum width allocated for an individual card in the card array, so that each card can carry its own identifying label.
  • the preferred mounting means for mounting the label on the printed circuit card is a pair of gripping fingers which are integrally formed with the label holder and which clip onto the edge of the substrate of the printed circuit card at any location permitted by the locations of components on the card with the label holder body extending along the length of the edge of the card from the gripping fingers. It is extremely important to the invention that the gripping fingers do not penetrate into or through the printed circuit card so that there is no chance of damaging the electrical components or conductors on the card. It is also important to the invention that the gripping fingers are much smaller than the length of the label holder body so that a location can be found for the gripping fingers along the edge of crowded cards without interfering with components projecting from the cards.
  • Fig. 1 is a perspective view of three printed circuit cards mounted on a single mother board with each card carrying a label holder of this invention, one of which is shown in exploded view,
  • Fig. 2 is an end view of the label holder shown in exploded view in Fig. 1.
  • the typical printed circuit board arrangement shown in the drawing includes a mother board 10 carrying a plurality of printed circuit card connectors 12, 14, and 16 which carry printed circuit cards 18, 20, and 22.
  • Each printed circuit card contains a substrate carrying electrical components such as 24 and 26 and conductors 28, and each printed circuit card is designed to fit within a standard volume with the components projecting from one side of the card toward the adjacent card by a maximum distance which is here the distance between the connectors 12 and 14. In this way each of the cards 18, 20, and 22 can be mounted in any of the connectors 12,
  • the label holder illustrated in the drawing includes a body 30 and a pair of gripping fingers 32 clipped onto the substrate of the printed circuit card.
  • the body 30 and fingers 32 are preferably made integral with each other molded of a resilient, non-electrically conductive plastic material such as polycarbonate plastic.
  • the fingers are inserted onto the edge of the printed circuit card at locations permitted by the components on the card.
  • the label holder is provided with a label identifying the printed circuit card either by writing on the label holder or by mounting an adhesive label on the label holder.
