Definitions

  • the present invention relates to a support for a plug-in card with electrical and thermal connection, comprising a common flat base carrying at least one connector in the form of a bar provided with a groove for receiving an edge of the card, the internal faces of a groove arranged opposite, carrying on the one hand electrical contacts and on the other thermal contacts in connection with a cooling member.
  • Printed cards used in plug-in circuits use increasingly large electrical powers and the problem of heat dissipation of the heat produced by the Joule effect arises.
  • the support according to the invention proposes to solve the problem posed by the evacuation of the calories generated by the circuits with high heat dissipation which are arranged on printed boards provided with a thermal drain as described in the German application cited above. .
  • the support for a plug-in card is characterized in that the connecting element is a thermal conductor supported by the bar and in that the cooler organ is formed by the plan comman base.
  • Fig. 1 shows a support with electrical and thermal connection, of known type, for circuit on card.
  • the support comprises a base 1, on which are fixed connectors in the form of a barrett such as 2.
  • Each bar comprises a groove with two opposite faces, 3 and 4, intended to receive an edge 5 of a circuit on a card 6.
  • One of the faces 3 of the groove is intended to ensure the electrical connection with the electrical circuit 7 carried by the card 6, and carries contact elements such as 8, endowed with elasticity by their material and their shape.
  • the second face 4 of the groove carried by the bar 2 is mobile, and can pivot around the point 9.
  • the card In the open position, it is easy to introduce the card, the position of which is defined by the stops 26 and 11, and the closed position, as shown in the figure, applies the card to the stop 11, and simultaneously compresses the contact 8 which bends by elasticity thanks to its part 20 and makes the electrical connection with the necessary bearing force.
  • a connection tab 21 allows connection with external circuits.
  • the thermal face 4 of the strip carries thermal contacts such as 22, made of material which is a good conductor of heat, and conveying the thermal energy to be eliminated thanks to a suitable surface section, by a transmission tab such as 23, in relationship with a cooler 24 provided with fins 25, and operating by air convection.
  • Such a connector operates as follows: the two faces 3 and 4 of the bar 2 are movable relative to each other, by rotation about the axis 9. In the phase of placing the card , the connector is open, the face 4 forms an angle which releases the face 3, and the introduction of the card 6 is carried out, positioned transversely by the stop 26.
  • the electrical contact occupies position 27, shown in dashes.
  • the card consists of two superimposed layers, an electrically insulating layer or substrate 6, carrying the electrical circuit 7 and its connection regions, and a layer 28 made of material with good thermal conduction, such as a metal for example, a layer often designated. under the term of thermal drain.
  • the connector closes, as shown in the figure, and the thermal contact 22 is applied to the surface of the drain.
  • the electrical contact 8 is pushed back and takes, by elasticity, the shape shown in solid lines in the figure.
  • the bearing force necessary for good thermal conduction between the drain 28 and the contact 22 is obtained by the elastic force provided by the electrical contact which makes it vis-a-vis.
  • a second stopper II parallel to the direction of installation of the card, fixes the amplitude of this to avoid that, by excessive compression of the contact, the elastic limit is not exceeded.
  • the introduction of the card can be effected by a sliding parallel to the grooves, or a translation perpendicular to the latter.
  • This support of known type is not satisfactory for the evacuation of the calories generated by circuits with high heat dissipation.
  • Fig. 2 shows an embodiment of the support of the invention, with conduction cooling.
  • the card is put in place by a translational movement perpendicular to the plane of the card.
  • the external part 30 of the cooler no longer has fins, and it only assumes the function of thermal conduction, in the direction of the arrows such as 31 from the thermal drain 28, towards the base 1, comprising an insulating layer 33 and a thermal drain base 34, made of thermally good conductive material.
  • a fixing means such as screws 35 ensures satisfactory obtaining of the two desired types of contact.
  • the thermal drain 28 of the card 6 is directed upwards in the figure, the thermal contacts of the support according to the invention also being arranged on the top, so that there is an evacuation of the calories present on the thermal drain 28 to the base heat sink 34 via a thermal conductive connecting element 30, said element being supported by the bar 2.
  • the support comprises four bars arranged on the common plane base according to a four-color rectangle.
  • the connector of the invention ensures satisfactory results as described above, it may be advantageous to improve the thermal transmission at the points of contact of departure and arrival of the thermal conductor by interposing a product there. fluid, pasty or plastic, based on silicones for example, in 36 and 37, which dispenses with too precise surface machining between the corresponding contact regions.
