Definitions

  • the invention relates to a connector of the so - called press fit type , that is to say plug-in force on a printed circuit board.
  • such a connector comprises an insulating body carrying a series of bent pins whose proximal branches (with respect to the card) are essentially perpendicular to the card and have a profile allowing the force-fitting in a metallized hole of the printed circuit. , and whose distal branches are essentially parallel to the card and are configured as a male or female connection member.
  • the force-fitting of the pins in the metallized holes of the card is in principle carried out once and for all (unless allowing two or three dismantling of the connector, for example for repair operations), while the connection members carried by the distal branches of the pins are intended to produce an essentially removable electrical connection, typically in the form of a socket located on one face of a box containing the electronic card on which the connector is mounted.
  • the mounting on the card of such a force-fit connector is generally carried out by direct pressing on the pins in their bent region, in order to cause the latter to sink into the metallized holes opposite.
  • the first drawback of this operation is that it requires specific tools for each connector in order to press simultaneously and uniformly on each of the pins of the connector.
  • connection members being oriented in a direction essentially parallel to the card, if the connector is not perfectly pressed against the latter, the axis of the connection members will be offset radially relative to the position that it should have occupied, thus preventing the subsequent realization of a satisfactory mechanical and electrical connection: the consequence is that, when the card provided with its connector will be placed in the box before receiving it, the connection members will not be located exactly arranged, relative to the box, in the exact location they would normally have occupied, if the insulating body of the connector had remained perfectly pressed against the surface of the card.
  • One of the aims of the invention is to remedy these various drawbacks by proposing a new force-fit connector structure which, on the one hand, does not require any specific tool for mounting on the card, therefore with the advantages correlative in terms of simplicity and low cost of implementation and which, on the other hand, guarantees a systematic plating of the insulating body carrying the pins - and therefore perfectly define the geometric position of the connection members relative to the box.
  • Figure 1 shows, in exploded perspective, the constitution of the insulating body of the connector.
  • FIG. 2 shows, in perspective, the connector of the invention, with its various elements assembled, ready to be plugged into a printed circuit board.
  • FIG. 3 is a section, seen in elevation, of the connector of FIG. 2.
  • Figures 4 and 5 are sectional views, respectively in elevation and in plan, of the connector of the invention in a first phase of the mounting operation on the printed circuit board.
  • Figures 6 and 7 are homologous to Figures 4 and 5 for a second phase of the mounting operation.
  • Figures 8 and 9 are equivalent to Figures 4 and 5 for a third phase of the mounting operation.
  • the connector of the invention shown in different aspects in Figures 1 to 3, essentially comprises an insulating body formed by two parts 100, 200 and a series of bent metal pins 300 opening into a metal housing 400 forming a shielding envelope.
  • the part 100 is a generally square-shaped part comprising a first wing 110, oriented parallel to the card 500 (FIG. 3) and which will subsequently be pressed against it, and which will be designated subsequently under the term of "mounting wing", and a second wing 120, perpendicular to the aid 110, which will be designated subsequently by the general term of "connecting wing".
  • This wing 110 has two holes 111 possibly allowing additional fixing on the card, or positioning of the bracket relative to centering pins defined on this same card.
  • the face 112 of the mounting wing facing the card will subsequently come into contact with the surface of the latter and will also serve as a reference surface defining the geometric position of the various elements of the connector.
  • the connecting wing 110 carries a number of cells 121 which will receive the bent pins, and notches 122 allowing the metal case 400 to be held in place by crimping tabs 410 thereof.
  • the connecting wing 110 also includes holes 133 allowing for example the mechanical connection of the connector to the box 600 containing all of the elements.
  • the other part constituting the insulating body of the connector is a part 200 hereinafter called “pressure block”, of generally parallelepiped shape.
  • This block comprises, on the side facing the card, notches 210 at the bottom of which will bend the bent pins 300, as can be seen more explicitly in FIG. 3, these pins coming to bear on the bottom 330 of the notches 210.
  • the block also includes front surfaces 230, defined for example by one of the side walls of grooves 240 and intended to come to bear against the inner face 113 of the mounting wing 110 in the manner which will be indicated in more detail by the after.
  • the block 200 is fitted onto the bracket 100, and for this purpose comprises a relief 250 coming to be placed in a homologous gutter 124 formed on the connecting wing 120 of the bracket; moreover, the grooves 240 cooperate with homologous ribs 114 of the mounting wing 110.
  • the pressure block 200 finally comprises a rear surface 260, essentially flat, against which a pressure force will be applied during the operation of mounting the connector on the card.
  • the pins have the general configuration illustrated in FIG. 3, namely an angled shape. They comprise a first branch 310, hereinafter called “proximal branch”, shaped as illustrated in 311 in order to allow forcing in a metallized hole of the printed circuit.
  • the other branch 320 which will be called “distal branch”, extends perpendicular to the branch 310, therefore parallel to the card; its end is configured, as illustrated in 321, as a male or female connection member (in the example of the figure, in the form of a female pin) so as to produce, in combination with the metal housing 400, an assembly connection for example emerging from the box 600 inside which are mounted the connector and the card.
  • the dimensional accuracy of the placement of the connector relative to the box 600 depends on the dimension d , that is to say the distance between the transverse axis of the connecting wing 120 and the surface of the card 500, so that any defect in placing the bracket against the card will be accompanied by a defect in positioning the connector relative to in box 600.
  • a tool 700 is pressed against the rear face 260 of the pressure block 200, a tool which can be very simple, with for example a simple planar face which the 'is subjected to a force F in order to urge the pressure block 200 - and therefore the entire connector with its pins - in a direction perpendicular to the card.
  • This phase ends when the front face 112 of the mounting wing comes into contact with the surface of the card, the pins 300 then being fully inserted into the metallized holes 510 of the card 500 (final position corresponding to the illustration in FIGS. 6 and 7).
  • the tool 700 is removed, which has the effect of releasing the pressure exerted on the various elements of the connector, and therefore of releasing the internal stresses accumulated during the previous phase , constraints due both to the proper deformation of the different parts of the insulating body and to the bending of the metal pins.
  • the clearance J2 If one has determined, by construction, the clearance J2 so that, on the one hand, it is less than the elastic deformation under stress of the pins (so that, during the second phase illustrated in FIGS. 6 and 7, the faces 113 and 230 come into mutual contact) and that, on the other hand, it is greater than the permanent deformation of the pins and of the insulating body after full insertion of the pins and release of the stresses (so that the final clearance J4 has a positive value , not zero), it can be seen that the outer face 112 of the mounting wing 110 will remain pressed against the surface of the card 500, thus ensuring optimal mechanical mounting and perfect respect for the dimension d defining the position of the connection members. contained in the housing 400 relative to the card 500.
