Definitions

  • the present invention relates to the field of connectors for circuits on plug-in cards.
  • Such cards are presented in the form of a quadrilateral plate, made of an electrically insulating material, supporting a plurality of electronic components and the connections which connect them, these being most often produced by depositing on the plate of an electrically conductive metal.
  • connection with the external use circuits is ensured by a plurality of contacts arranged on one or more sides of the plate, cooperating with contacts of complementary shape forming part of a fixed connector connected to the use circuits; this connector generally provides a second function, that of mechanical support of the card in the equipment where it is implemented.
  • the connectors Due to the quadrilateral shape of the plate, the connectors thus take the general structure of elongated blocks in the form of bars, sometimes arranged at right angles on a common flat base.
  • connection bars are four in number, defining a closed quadrilateral
  • the installation for connection and fixing of a plug-in card requires the realization of the connection bars in two parts, capable of '' a relative movement with respect to each other, leading to an implementation in two phases: phase of introduction of the card, corresponding to an open position of the mobile part, phase of connection and fixing of the card , corresponding to the closed position of this part.
  • a terminal strip forming part of such connectors is thus most often in two main parts, made of insulating material, namely a fixed base and a cover provided with rows of conductive contact elements, and joined by an axis of rotation. longitudinal allowing to realize the two open and closed positions indicated above.
  • the closed position applies the contacts of the connector against the plates with a force obtained by choosing an elastic material for constituting them, and essential for ensuring contacts with low electrical resistance.
  • a tightening by screw is generally used between the base and the cover, placed either at the ends of the latter if the bar is short, or at locations distributed along of the bar if it is long.
  • connection device has a major drawback: the operations of connecting and disconnecting the card require accessibility to the part of the base located under the contacts at the axis of rotation of the clamp. This means that such a base cannot be opened or closed when it is fixed to a printed card or any support.
  • connection strip capable of being fixed a support, and making it possible to connect a printed card while maintaining said strip on the support.
  • the connector which is the subject of the present invention does not have any of these drawbacks.
  • connection-disconnection operations corresponding to the closing and opening stages, are practically instantaneous.
  • the invention separates, for the base and the cover, the respective functions of supporting contact elements, and of applying support pressures, which they assume in the connectors of the known art. . It retains only the first for them, and entrusts the second to a different means, creating by elasticity the pressing pressures whose cover ensures only transmission, and endowed with great longitudinal rigidity.
  • This means has the general shape of an angle iron or U-shaped section, "horseshoe-shaped", the great longitudinal rigidity of which is known, and the part which is provided with elasticity thereof is the base of the connecting section, on a section view, the two sides of the horseshoe.
  • the invention consists of a connection strip for a plug-in card, consisting of a base in a rectangular cover supporting a plurality of electrical contact elements provided with elasticity, the cover being able to pivot about an axis. longitudinal parallel to the base, taking two positions, respectively opening for placing the edge of a card, and closing for bringing the respective conductive elements of the strip and the card into contact, as well as '' a pliers in the shape of a profiled beam with a U-section, the two branches of which bear respectively on two zones of the base and of the cover, the said pliers being arranged parallel to the longitudinal axis of the bar, and near the latter, these branches, of unequal lengths, ensuring closure by application of a force obtained by elastic deformation of the connecting base of the two branches, said bar further comprising means of cooperation of the bran che lower short and the tie, characterized in that the cover comprises at least one stud cooperating with at least one corresponding housing carried by the long upper branch of the clamp, allowing the attachment of
  • Figure 1 shows, in a partial perspective sectional view, a plug-in card connector according to the prior art.
  • This connector consists of a base 1, a cover 2, which can pivot relative to each other about the axis 3, and a plurality of contact elements such as 4.
  • the card 5 being placed in the open position of the connector around the axis 3, the closed position compresses the elastic parts 6 and 7 of the contacts, the reaction of which exerts a force F tending to spread the cover of the base.
  • a plurality of screws such as 8 and 9 are used.
  • FIG. 2 shows, in a sectional view, a connection strip for a plug-in card according to the invention.
  • It comprises a base 11, a cover 12 pivoting about the axis 13 and a plurality of contacts such as 14.
  • a separate means constituted by a profile 15 in the form of a beam with U-shaped section or "horseshoe”, section comprising two unequal branches 16 and 17, and a connecting base of the branches 18.
  • This profile which in the following will be designated, by way of simplification, by the name of clamp, is made of an elastic material such as stainless steel. It performs two functions, namely on the one hand the application of a closing force of the bar opposing the elastic forces tending to open it, developed by the contacts, and on the other hand, as a result of the characteristic of longitudinal rigidity of the U-section beams, the function of maintaining the longitudinal linear shape of the cover, which it replaces in this aspect of non-formability.
  • the clamp is fixed by projecting parts 19 and 20 carried by the bar, cooperating with regions of complementary shape carried by the clamp
  • Figure 3 shows, in a perspective view, a closure clip according to the invention. It is presented, in section, along a U-shaped beam with unequal branches 16 and 17; the short branch 17 is provided with a bead 30 for fixing in a housing carried by the base of the bar, and the long branch 16 carries openings such as 31 intended to cooperate with tenons 19 carried on the cover, and visible in Figure 2.
  • Openings 32 are arranged in the connecting base 18 of the branches, the role of which is to allow, by choice of their dimensions, the precise adjustment of the elasticity of the clamp. They can have another role, which will be explained later, when the bar is opened.
  • the clamp carries, at the ends of the long branch 16, two longitudinal tenons 33 and 34, which can penetrate into open housings formed on the upper part of the cover, by constituting pivot pins securing the clamp and the cover, in position opening hours.
  • Figure 4 gives, in a schematic section, an explanatory diagram of the operation of the connection strip.
  • the clamp 15 mounted on the bar exerts on its two parts two equal and opposite forces F1 and F2.
  • the force F exerted by the contacts on the two parts tends to open the bar.
  • the advantageous result of the invention is to obtain that F11 1 and greater than F, uniformly over the entire length of the bar, without the need, as explained above in detail, for perfect rigidity of the cover, which can thus be made of a deformable plastic material of small thickness with respect to the length.
  • FIG. 5 and 6 show a clamp opening device forming part of the present invention.
  • the opening can be obtained by extracting the short branch from its housing using any tool inserted between the connecting base 18 and the base of the bar 11.
  • a particularly advantageous means is constituted by a bent lever 50, the bent part 51 of which can be introduced into one of the openings 32 of the connecting base, in position (a) in FIG. 6.
  • the bent part 51 is supported simultaneously on the base and the connection base, causing the extraction of the clamp, and its rotation around the pins 34, pivoting in the open housings 35 carried by the upper face of the cover 12.
  • the invention thus provides the possibility of producing overlapping plug-in cards with very small spacings, the closing clip, being part of the connection strip of the invention being very thin, and requiring no additional spacing for its placement. in place and its removal, which by the way are practically instantaneous.
