Definitions

  • the present invention relates to an electrical contact member for the connection of electrical connection lugs to a printed circuit.
  • this connection is achieved by depositing a conductive cream at the location where the pod passes through the circuit, in contact with an electrically conductive track.
  • the cream is then heated by microflam or hot air, which causes its melting and then hardening on cooling.
  • the present invention aims to overcome these disadvantages.
  • the subject of the invention is an electrical contact member for the connection to a printed circuit of a connection lug, characterized in that it comprises a metal body composed of a set of lateral faces delimiting a substantially parallelepipedal space, said body being arranged to be housed in a hole of corresponding shape pierced in the circuit, and protruding extensions of said faces for crimping said member in said orifice, at least one of two of said faces facing each other being shaped so as to approach the other in its central part so as to pinch by elastic deformation said lug engaged in said space.
  • said faces facing each other are the large faces of the parallelepiped.
  • At least one of said extensions is welded to a conductive track of said printed circuit.
  • the main advantage of the invention lies in the fact that the contact member according to the invention can be easily introduced into the hole provided for this purpose. effect, then crimped and finally welded to the wave at the same time as the components mounted on the printed circuit. The crimping and welding operations are performed at the same time for all the contact members of the circuit. Then, the lug is engaged in the central space and the connection is carried out simply by dry elastic contact.
  • the contact member 1 is made in one piece of metal sheet, for example of the order of 0.2 mm thick.
  • It is formed essentially of a parallelepipedal body 2 delimited by two small end faces 3 and 3 ', and two large longitudinal faces 4 and 4'.
  • the height h of the body 2 is slightly less than the thickness e of the printed circuit 5 for which the member 1 is intended.
  • the large faces 4 and 4 'of the body 2 are not flat, but are gradually approaching each other upwards, in their longitudinally median parts, 6 and 6' respectively. Each of these faces thus forms a kind of vault whose concavity is oriented towards the outside of the body 2.
  • each major face Along the lower edge of each major face, a longitudinal projection is cut and folded substantially perpendicular to this face towards the outside of the body, to form a flap 7 abutment. We will see below the usefulness of these flaps.
  • a crimping tab 8 allows the assembly of the member 1 on the printed circuit 5.
  • the member 1 is introduced from below into a hole 9 drilled in the circuit 5, until the flap 7 abuts against the lower face 10 of the circuit.
  • the ends of the lugs 8, which protrude from the upper face 11 of the circuit, are then folded against this face so as to crimp the member 1 in the hole 9. It will be observed that, in this case, the lugs 8 are folded over a conductive track 12 of the circuit 5.
  • This assembly of the members 1 on the circuit 5 is performed in the context of the introduction of the electronic components on this circuit.
  • a cover 13 is then introduced into the central space of the member 1 so that its end surface 14 is flush with the surface 11 of the circuit.
  • the circuit board 5 thus equipped is passed to the wave soldering machine to weld the components and the members 1.
  • the cover prevents the molten metal from rising in the hole 9. It is seen in the figures a weld 15 between a leg 8 and a conductive track 12, after removing the cover 13.
  • Figures 2 and 3 show a lug 16 engaged in a connecting member according to the invention.
  • the pod elastically spreads the vaulted portions 6 and 6 'of the faces 4 and 4'. Because the end portions of these faces are locked longitudinally and resting against the flanks of the hole 9, there is an arching of the arch portions 6 and 6 ', which ensures a firm contact between the lug and the lug. liaison body.
