Definitions

  • the present invention relates to a contact insertable into a metallized hole of a printed circuit board, as well as a method of inserting this contact into the metallized hole.
  • Contacts that can be inserted by force into the metallized holes of a printed circuit board are widely used today for making solderless connections. They generally have a first end intended to pass through the hole and protrude beyond one of the faces of the card when the contact is in the insertion position, and a second end intended to protrude beyond the other side of the card. These two ends are connected by a middle part whose function is to simultaneously ensure the electrical connection of the contact with the metallized interior surface of the hole, and its mechanical retention in the hole.
  • the invention relates more particularly to the middle part of these contacts, whose configurations known up to now can be classified according to two distinct groups.
  • a certain number of contacts have a prismatic, non-deformable middle part, with rectangular or square section.
  • the edges of the middle part which extend parallel to the longitudinal axis of the contact or to its direction of insertion into the hole, become embedded in the wall of the covering. inside the hole, thus forming gas-tight connections which slow down corrosion phenomena at the level of the contact surfaces.
  • these contacts have a number of disadvantages.
  • the large forces which develop in the axial direction can cause the tearing of the internal coating, or of the intermediate conductive layers in the case of the use of circuits. multilayer.
  • the axial retention of the contact which is effected only by friction of the contact on the coating, will be poor and may still deteriorate under the action of mechanical stresses ( vibrations, axial forces exerted on either end of the contact) or thermal. It can therefore be seen that the use of this type of contact implies compliance with very strict dimensional tolerances on the opening of the printed circuit, which are difficult to obtain by electroplating techniques.
  • the object of the invention is to provide an insertable contact which ensures both excellent mechanical strength and very satisfactory gas tightness and which does not have any of the disadvantages of known contacts while allowing a relaxation of tolerances. dimensions attached to the metallized hole of the printed circuit board.
  • the contact comprises a first end 1, of generally square section, intended to project beyond one of the faces of a printed circuit board so that it can receive an electric wire secured by means of a coiled connection.
  • the second end 2 not shown in the drawing is intended to project from the other face of the printed card and facilitate the connection of a secondary printed card, an electric wire or any other device.
  • the ends 1 and 2 are connected by a middle part 3 which has a helical structure.
  • the section of the middle part 3 is polygonal, preferably rectangular (FIG. 5) or square, and its vertices define the edges 4 of the helical structure.
  • the angle of rotation of the propeller is preferably 90 °, that is to say that the pitch of the propeller corresponds to the length of the middle part.
  • FIG. 4 represents the contact in the insertion position in a hole 5 of a printed circuit board 6, internally covered with a conductive coating 7.
  • a shoulder 8 having at least two flat surfaces 9, 10 perpendicular to the axis longitudinal contact is provided at the junction of the middle part 3 and the second end 2, to bear against the upper face of the printed circuit in the contact insertion position.
  • the contact is best implemented by simply exerting on its second end 2 a longitudinal thrust towards its end 1, and maintaining the free contact in rotation during at least the phase of penetration of the middle part into the hole. The contact therefore penetrates by turning into the wall of the coating 7.
  • the surfaces 9 and 10 then make it possible to fix the axial position and consequently the angular orientation of the contact in the insertion position.
  • these same surfaces 9 and 10 allow the forces applied to the end 1 to be transferred directly to the upper face of the card 6 during a connection operation by winding, in particular if the pitch of the helical structure is of the type on the left, while the winding connection is generally made clockwise.
  • a groove 11 is produced at the junction of the surfaces 9, 10 and the central part 3 to avoid any positioning defect caused by irregularities in the covering 7 at the entrance to the hole 5.
  • the length of the middle part 3 corresponds to the greatest depth of the holes capable of receiving it.
  • the length of the diagonals of the section of this middle part must be slightly greater than the average diameter of the opening defined by the walls of the covering 7.
  • Figure 6 shows by way of example a series of contacts during manufacture.
  • the cutting, bending and forming operations are carried out using a metal strip 12, for example in phosphor-bronze or tin-bronze, the individual contacts of which may be separated along a line X only by the end user of the contacts, before their insertion into the printed circuit boards.
  • the contacts shown in this figure, like that of Figure 7, have a second end 2 forming an elastic fork 13 provided for the connection of printed cards for example.
  • the contact of Figure 8 has a second end also forming a connection terminal by winding, for example to make a connector for flat cables. The coating of the different zones of these contacts can be obtained by the usual techniques.
  • the manufacturing operations advantageously provide for a step during which a twist of 90 ° is applied to one of the ends of the contact relative to the other, around the longitudinal axis contact, so as to give the middle part the desired helical configuration.
