Definitions

  • the invention relates to a set of electromagnetic relays and applies to the connection of one or more electrical circuits to one or more common circuits, which may for example be power bars.
  • the invention also applies to space connection networks such as are encountered in telecommunications, where to establish communication two so-called vertical bars must be connected to two horizontal bars.
  • US Pat. No. 2,932,705 discloses a relay, the electrical contacts of which are closed by displacement of a movable contact towards a fixed contact, using a drive device integral with the pallet of a first electromagnet, a second electromagnet ensuring, by its pallet, the locking of the drive device when it is actuated by the pallet of the first electromagnet when the latter is energized.
  • the drive device is an insulating plate comprising slots in which the upper end of each movable contact is engaged, one end of the plate being integral with the pallet of the first electromagnet, another end of the plate comprising a finger allowing 'hooking of the wafer by the pallet of the second electromagnet when it is supplied after the first electromagnet.
  • a relay with an electrically controlled locking mechanism is also known from patent FR-A 716 020.
  • movable contacts are mounted on a movable control shaft and cooperate with fixed contacts; one end of the shaft is secured to a frame cooperating with an electromagnet, and another end of the shaft comprises a lever which cooperates with a latch mounted on a pivot, said latch holding the control shaft and the movable contacts in closed position.
  • a release electromagnet is connected by a connecting rod to the latch.
  • the object of the invention is a multiple relay allowing the closing of a single electrical contact among several by displacement of a single movable contact, and prohibiting the closing of another electrical contact while another electrical contact is closed.
  • Figure 1 shows a multiple relay
  • a U-shaped support 1 consists of a base 2 and two branches 3 and 3 '; on the base are fixed an electromagnetic control relay 9, and electromagnetic relays 8; a common insulating bar 4 pivots about an axis 5 fixed in the branches 3 and 3 '; the common bar 4 is located above the electromagnetic control relay 9 and the electromagnetic relays 8, and comprises over its entire length two conductive bars 6 and 7 having respectively a folded tab, called semi-fixed contact, 10, 11, opposite of each electromagnetic relay.
  • a return spring not shown, makes it possible to return the common bar 4 to the rest position when it has pivoted.
  • Each electromagnetic relay comprises a magnetic circuit 12, a mobile element 13, a stop 14, terminals 15 and 16 each connected respectively to two contacts carried by the mobile element; a cover 17 protects all of the electromagnetic relays.
  • Figure 2 is a view along section II-II of the multiple relay, section made at the electromagnetic control relay. In this figure we find the base 2, the common bar 4 with the conductive bars 6 and 7.
  • the electromagnetic control relay comprises a coil 20 wound on an insulating carcass 21, a magnetic circuit 22 open at 23 and fixed to the base by a screw 24.
  • the common bar 4 comprises a flap 25 provided with a pallet 26 of magnetic material, opposite the opening 23 of the magnetic circuit.
  • the common bar 4 has at each end a cylindrical part 27 in which the axis 5 is engaged, thus allowing the pivoting of the common bar; when the electromagnetic control relay is supplied, the pallet 26 is attracted and comes against the magnetic circuit 22, which causes the pivoting of the common bar upwards.
  • a pin 28 is connected to one end of the coil 20; the multiple relay is plugged into a printed circuit board 29.
  • Figure 3 is a view along section III-III of the multiple relay, section made at an electromagnetic relay.
  • the electromagnetic relay comprises a coil 31 wound on a carcass 32, insulating, a magnetic circuit 12 open at 33 and fixed to the base by a screw 34.
  • a movable element 13, insulating, is provided with a pallet 35, made of magnetic material, opposite opening 33 of the magnetic circuit.
  • the moving element 13 is crossed by two contacts which will be called movable contacts in the following description; a single movable contact 36 is shown in the figure, the other movable contact being behind, as can be seen in FIG. 1, each movable contact being double and constituted for example by two wires as is conventional in electromagnetic relays; the movable contact is inserted in the base 2 and its end constitutes a pin 37.
  • the common bar being in the rest position, the electromagnetic control relay not being supplied, the upper end of the movable contact 36 comes opposite a semi-fixed contact 10 for example, the end of the other movable contact coming opposite the semi-fixed contact 11, each semi-fixed contact 10 and 11 being constituted, as has been said, by a folded tab of the conducting bars 6 and 7, respectively.
  • the movable element comes against the stop 14 which is for example a metal blade inserted in the base.
  • a pin 38 is connected to one end of the coil 31.
  • the electromagnetic relay is plugged into the printed circuit board 29.
  • each movable contact 36 being opposite a semi-fixed contact, 10 or 11, at rest, it is necessary to pivot the common bar 4 to release the upper end of the movable contacts before supplying the electromagnetic relay in order to attract the pallet 35 and thereby the movable element 13.
  • FIG. 4 represents the supply connection of a conductive bar, for example 6, having a tab 40 on which is fixed a connection 41, constituted by metal wire, or a metal strip, inserted in the base 8 and acting as spring, the end of the connection projecting from the base constituting a pin 42.
  • connection 41 constituted by metal wire, or a metal strip
  • FIG. 4 represents the supply connection of a conductive bar, for example 6, having a tab 40 on which is fixed a connection 41, constituted by metal wire, or a metal strip, inserted in the base 8 and acting as spring, the end of the connection projecting from the base constituting a pin 42.
  • the connection 41 which acts as a return spring
  • the conductive bar 7 can also have a connection acting as a return spring, this connection being situated for example at the other end of the common bar 4.
  • FIG. 5 schematically represents the successive stages of the establishment in a, b, c, d, e, and of the release in f, of the contacts of an electromagnetic relay 8 of the multiple relay.
  • a semi fixed contact 10 of the common bar and a movable contact 36 of the electromagnetic relay 8 have been shown, it is understood that the operation relates to the two semi fixed contacts of the electromagnetic relay which are integral with the common bar, and the two movable contacts which are integral with the movable element of the electromagnetic relay.
  • the multiple relay is in the rest position; the semi-fixed contact 10 is in the low position, the coil of the electromagnetic control relay not being supplied; Similarly, the coil of the electromagnetic relay 8 is not supplied, the movable contact 36 is in the rest position.
  • FIG. 5f represents the release of the electrical contact between the semi-fixed contact 10 and the movable contact 36.
  • the coil of the electromagnetic control relay is supplied; the common bar pivots and the semi-fixed contact 10 assumes the high position, thus releasing the movable contact 36 which returns to its rest position.
  • the supply of the coil of the electromagnetic control relay is then removed and the semi-fixed contact returns to its rest position; we then find the position of Figure 5a.
  • the release of the electrical contact can also be obtained in the following manner, from FIG. 5e: the coil of the electromagnetic relay 8 is supplied, which brings about the attraction of the movable contact 36, and the position of the figure is found again. 5d; the coil of the electromagnetic control relay is then supplied and the semi-fixed contact 10 takes the high position, thus releasing the movable contact 36 as shown in FIG. 5c; the supply to the coil of the electromagnetic relay 8 is cut off and the movable contact 36 returns to the rest position, as shown in FIG. 5b where the position of FIG. 5f is found; the supply to the coil of the electromagnetic control relay is then cut off and the semi-fixed contact 10 returns to the rest position, as shown in FIG. 5a.
  • the coils of the electromagnetic relay 8 and the electromagnetic control relay are supplied for the time strictly smelled by the closing or opening of the electrical contact, the maintenance of the electrical contact not requiring no current.
  • each of the conductive bars 6 and 7 represents a horizontal bar and each movable contact of an electromagnetic relay is connected to a vertical bar.
  • two connection points must be established, i.e. an electrical contact between a moving contact of an electromagnetic relay and a semi-fixed contact of a busbar, and another electrical contact between another movable contact of said electromagnetic relay and a semi-fixed contact of the other busbar.
