Definitions
- the present invention relates to an electrical switching device comprising at least two stationary contact elements constituted by elongated conductive parts, folded to have the general shape of a U and implanted in a printed circuit board so as to be each in electrical contact with a conductive track of the plate, and a movable contact element disposed on translation means displacing, on command, the contact element perpendicular to its length.
- the prior documents FR-A-2 461 980, DE-A-2 657 546 and DE-A-2 403 108 describe electrical switching elements comprising stationary contact elements which are elongated conductive parts, folded to have the shape general of a U and located in a printed circuit board, so as to be each in electrical contact with a conductive track carried by the board.
- the movable contact element moves perpendicular to the plane of the stationary contact elements.
- the switching device is characterized in that the movable contact element is moved in the plane of the stationary contact elements and in that the translation means comprise a cursor arranged on a slide and carrying the movable contact, stop means being provided to define precise stop positions of the cursor.
- the stop means comprise a rack integral with the slide cooperating with a ball pushed by a spring and carried by the slider.
- the slide can be a molded part attached to the printed circuit board and comprising at least one imprint ending in perforations, arranged so as to receive one of the stationary contact elements which will pass through the slide to be implanted in said plate.
- each stationary contact element is a section of wire, strip or profile, made at least in part of a conductive metal such as copper or a copper alloy.
- Each stationary contact element can be placed on the printed circuit board by an automatic implantation machine for components and soldered like these, for example by wave soldering.
- each stationary contact element is coated, at least where the movable contact element comes to rest, with a precious metal such as silver or an alloy of this metal.
- At least two stationary contact elements are arranged side by side and in that the movable contact element is an elastic contact blade which is subdivided into two strips by a partial longitudinal slot, the respective dimensions being such that each strip is supported independently of the other on one of the stationary contact elements.
- 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, component that the machine is intended 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 offer, as an example ple, 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 according to 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 elements of stationary contact 16 and 17, independently of each other, to a certain 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 part 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.
- a series of locations of stationary contact elements By examining the neighboring location 32, we sees that it comprises an opening 33 through the part 31. Between this opening 33 and the lower edge 34, a hollow imprint forms the ramps 14 and 15 of FIG. 1, at the bottom of a shallow groove, so that the stationary contact element 1 is projecting relative to 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 changing position; the blade 23 is wide enough to be still supported by a stationary contact element when it reaches the next, in most cases. When this is not the case, the plate comprises, between the more distant stationary contact elements, a boss 43, 44 which lifts the blade 23 by its stop 45 and then lets it fall back at the level of the contact by its flank 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 which is 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. It can be recognized therein 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 longitudinally by any means.
