Definitions

  • connection terminal comprising a flat metallic piece of small thickness which has a contact surface equipped with a screw and which is provided with protruding parallel lugs capable of penetrating into openings of a printed circuit board. so as to be soldered with a conductive layer of this circuit.
  • Such terminals which are frequently used to transmit small currents, are generally placed side by side using an insulating support to form a connector able to cooperate, for example with a multiplicity of conductors, the screws being generally arranged. so that their axes are substantially perpendicular or slightly inclined relative to the plane of the map; in order to give the ends of the conductors a satisfactory tightening, the screws are generally associated with a solid metal part which has a common opening where the ends of the conductors and the respective contact surfaces will be applied against each other.
  • multiple terminal connector devices for printed circuits in which the currents to be transmitted are greater, use a multiplicity of flat parts each having two parallel tabs suitable for being soldered with a conductive layer placed on the side opposite to the connector, and comprising each a contact surface carried by a tongue capable of cooperating with an elastic clip or socket fixed by crimping on one end of the conductor, an insulating holding device being associated with these flat parts.
  • connection terminals have the drawback of being either only intended for the transmission of low currents, or of being fragile in the absence of additional holding means or when the number of flat parts is low, and to use expensive removable connecting members.
  • connection terminal whose general constitution corresponds to that which is mentioned above and which is capable of transmitting high currents, while having a significant inherent solidity and a reduced cost of implementation, without using additional holding means.
  • the metal part has two wings, folded around a common edge perpendicular to the card, so as to make between them a determined angle, and has three legs, the one is close to the edge, while the other two are remote from the latter, a threaded hole capable of cooperating with a terminal screw being disposed in one of the wings so that its axis is substantially parallel to the plane of the card, the parallel tabs being engaged in metallized openings of the card and welded therewith.
  • This terminal mainly comprises a metal part 5 which is visible, in particular, in FIG. 1a and which is obtained by folding, around an edge 7, a cut flat part 5 "', so as to form two wings 5 'and 5 "forming a determined angle between them, see also Figures 1b and 2.
  • This part 5 has on the wing 5 ′ a contact or connection surface 6 which is provided with a threaded opening 8 of axis XX ′ perpendicular thereto.
  • a clamping member 10 comprising a screw 11, having a head 12 and a pierced stirrup 13 which is placed under this head.
  • the part 5 In the vicinity of the two opposite ends 14, 15 of the two wings and respectively of the edge 7, the part 5 has three parallel legs 16, 17, respectively 18, which are placed in the planes where the two respective wings circulate.
  • Two aligned edges 19 and 20 of the part 5 are located between the legs 17, 18, respectively 18, 16, before the cut part 5 "'is folded and are placed in the same plane RR', visible in FIG. 3 , when the part 5 has been folded, the edge 7 being substantially perpendicular to this plane
  • the conductive layer 3 and the insulating plate 2 are pierced with three openings 22, 23, 24 internally metallized whose spacings correspond to those of the tabs 17 , 18 and 16 so that the part 5 can be associated with the printed circuit board 1 by making these tabs penetrate these openings, see FIG. 3, until the edges 19, 20 come in close proximity to the layer 3.
  • a weld bead 21 is deposited on the conductive layer so as to simultaneously wet, on the one hand the edges 19 and 20 and, on the other hand, the tabs 18, 17, 16 and the corresponding metallized holes.
  • the axis XX 'of the screw 10 is substantially parallel to the plane PP' of the card 1, and is separated from the neighboring face 27 thereof by a distance "d" such that an edge 25 of the rectangular-shaped stirrup 13 is guided without turning during the tightening of the screw; the orientation of a cambered stirrup, shown in FIG. 2, can be made so that the ends of the conductors are introduced between it and the contact surface 6, either parallel or perpendicular to the plane of the card 1.
  • the angle a and the lengths of the wings will be chosen so that the forces exerted axially and angularly on the terminal by a screwdriver are much less than the resistant fixing torques opposed by the latter and so that the end of the screw does not come lean on the 5 "wing. Angles between 45 ° and 135 ° were satisfactory.
  • an apparatus 31 comprises a thin insulating box 32 which has a bottom 37 and a central volume 33 surrounded by peripheral walls such as 34, 35, 36.
  • a flat insulating cover 43 closes the volume 33 and holds the card to which it is parallel; the cooperation of the housing walls and the terminal screws is advantageously provided to make them captive.
