Definitions

  • the subject of the present invention is an electrical switching device and, more particularly, a device of the type comprising in particular a stationary contact element, a movable contact element as well as means intervening in the position of the movable contact so that the latter is maintained on command by pressing against the stationary contact element and thus establishes an electrical circuit.
  • the main object of the invention is to achieve a particularly economical switching device. It relates to a switching device intended to be used in connection with circuits of a printed circuit board.
  • the stationary contact element takes the form of an elongated conductive part, folded back to have the general shape of a U and implanted in a printed circuit board, so as to be in electrical contact with a conductive track carried by this plate.
  • This piece which can be a section of wire, strip or profile, is fixed to the printed circuit board by welding to at least one platform associated with a printed track, which performs both the mechanical fixing and the connection. electric.
  • this stationary contact element is put in place and welded like the other components carried by the plate. In a particularly economical form of implementation, it is put in place by an automatic implantation machine, at the same time as other components, and it is welded at the same time as the latter by wave welding.
  • This stationary contact element will be at least partially made of a conductive metal, such as copper or a copper alloy. This metal must also be suitable for welding. Finally, it can be at least partially coated with precious metal, for example silver to improve its contact characteristics.
  • said switching device comprises at least two stationary contact elements as defined above and the movable contact element is arranged to come to bear simultaneously on the two stationary contact elements.
  • the movable contact element is an elastic blade disposed on translation means arranged to bring the movable contact element to bear on the two stationary contact elements.
  • said means of translation will allow said elastic blade to be displaced perpendicularly to its length.
  • these two stationary contact elements will be arranged side by side, parallel to the length of said elastic blade.
  • the spacing of the two stationary contact elements and the width of the elastic blade will be such that the blade can bear at its end on these two stationary contact elements at the same time.
  • a longitudinal slot will advantageously be provided in the elastic blade in order to subdivide it into two strips which are supported independently on the two stationary contact elements.
  • These two stationary contact elements can also be arranged in the extension of one another, the length of the blade being such that it can rest on them.
  • two pairs of stationary contact elements side by side are arranged in the extension of one another and said movable contact element is a cylindrical element comprising a fusible wire arranged to come to bear, each of its ends, on the two elements of the same pair.
  • said translation means will comprise a cursor arranged on a slide and carrying said elastic blade.
  • Stop means will define precise stop positions of the cursor, with respect to which the stationary contact elements will be precisely arranged.
  • These stop means can take the form of a rack secured to the slide cooperating with a ball pushed by a spring and carried by the slider.
  • the slide will be a molded part attached to the printed circuit board. It will include imprints ending in perforations, arranged to receive stationary contact elements, thus implanted in the printed circuit board through the slide and thereby mechanically fixing the slide to the plate.
  • Figure 1 shows a stationary contact element 1 designed in accordance with the present invention.
  • This stationary contact element 1 is a section of copper wire bent to have the general shape of a U and comprising two legs 2 and 3 which pass through a printed circuit board 4, by perforations 5 and 6 made in this plate 2 , and the ends 7 and 8 of which are folded inwards and taken up in drops of solder 9, 10 secured to welding platforms 11, 12.
  • the stationary contact element is thus mechanically fixed to the plate 4. It is electrically connected to a printed circuit track comprising, for example, the platform 11.
  • the plate 4 is seen in section to the right of the element 1 and we also see in the figure a support element 13 also seen in section at this location.
  • the surface opposite to the plate 4 of this support element 13 is in fact an open angle formed by slightly inclined ramps 14 and 15.
  • the contact element takes on such a shape, the utility of which will be seen later.
  • Such a stationary contact element can be easily produced using an automatic component implantation machine provided with the appropriate settings and supplied with wire of appropriate diameter.
  • the machine cuts a section, folds it into a U, presses it against the support element 13 and folds the ends 7 and 8. It is no more and no less than a strap, making up the machine to set up like the other components, and which will later be welded with these in a wave welding machine.
  • Figures 2,3 and 4 propose, by way of example, several modes of construction of a switching device according to the invention.
  • FIG. 2 In the example of Figure 2, two stationary contact elements 16 and 17 similar to that of Figure 1 are arranged side by side.
  • a movable contact element 18, in the form of an elastic blade of conductive metal can be moved in both directions along the arrow 19, that is to say transversely and come to bear on the stationary contact elements 16, and 17.
  • this blade is provided with a slot 20 formed from its end on the side of the stationary contact elements and running over their entire length, in order to subdivide it into two strips which are supported respectively on the stationary contact elements 16 and 17, independently of each other, to some extent at least.
  • the stationary contact elements 21 and 22 are arranged in the extension of one another and the movable contact element 23, also movable transversely, comes to rest on them by its two ends.
  • FIG. 4 illustrates another embodiment of the invention in which two pairs of stationary contact elements side by side (24,25; 26,27) are arranged in the extension of one another.
  • the movable contact element is a cylindrical element internally comprising a fusible wire and the two ends 29 and 30 of which each rest on a pair of stationary contact elements.
  • a fuse circuit breaker is thus produced.
  • means not shown must maintain with sufficient pressure the fuse against its supports.
  • FIG 5 provides an illustration of an embodiment of the switching device of the invention in which we will find the stationary contact element of Figure 1, the movable contact element of Figures 2 and 3 and even the variant of Figure 4.
  • a molded part 31 serving as a slide and comprising a rack.
  • This part comprises centering pins, not shown, on its face facing the plate 4, and which correspond to holes in this plate, with a view to placing them in precise mutual position.
  • Other pieces can also be used to seal the two pieces together.
  • This piece. 31 comprises, along its lower edge (in FIG. 5), a series of locations of stationary contact elements, only one of them being shown at 1.
  • 'It comprises an opening 33 through the part 31.
  • a hollow imprint forms the ramps 14 and 15 of Figure 1, at the bottom of a shallow groove, so that l the stationary contact element 1 is projecting from the main surface of the part 31.
  • a cursor 35 comprising an operating button 36 carries an elastic blade 23. It moves transversely, sliding on guide surfaces by means of guide wings 37,38,39,40,41,42.
  • the elastic blade 23 serving as a movable contact element comes to bear on only one of the stationary contact elements at a time. Its width and the spacing of these elements have been chosen for this purpose. However, when the position is changed, the blade 23 is wide enough to be still supported by a stationary contact element when it reaches the next one, in most cases.
  • the plate comprises, between the more distant stationary contact elements, a boss 43, 44 which lifts the blade 23 by its edge 45 and then lets it drop at the level of the contact by its side 46.
  • the different stop positions that the slider 35 can take are defined by a rack 51 having recesses 52 and projections 53.
  • An elastic member, such as a ball pushed by a spring is provided in the body of the slider 35 for s '' press against the rack 51.
  • Each of the stationary contact elements such as that which appears in 1 being welded, through the part 31 to the plate 4 being in electrical conductivity with a conductive track 54, the displacement of the cursor driving the blade 23 selectively brings the electrical circuit associated with one of the lower contact elements such as 1 and that associated with one of the upper contact elements such as that which can be installed at 49.
  • Figure 6 is a partial section along the axis of the cursor 35.
  • the plate 4 the part 31, a stationary contact element 1 and a stationary contact element 56 perpendicular to the previous one.
  • the blade 23, simply slid between the wings 41 and 42 (fig. 5) can be retained.longitudinalement by any means.
  • a projecting notch 61 can be used for a visual indication of the position of the cursor.
