Definitions

  • the present invention proposes to produce an apparatus in which the control is simple and economical and allows a operation of the device in several different modes.
  • the apparatus according to the invention is characterized in that said member control comprises a link articulated at one of its ends on the pallet and at its other end on the pendulum, the point of articulation on the pendulum being able be moved to at least two separate locations on either side of the axis fixed of said pendulum, depending on whether the device is used as a breaker, contactor or inverter.
  • the device comprises a spiral spring provided with end branches, one of which bears against the end of the rod at its point of attachment with the pendulum and the other of which is in abutment a fixed stop.
  • the apparatus 10 consists of a miniature molded housing 11 which contains an electromagnet 12, a control mechanism 13 and a circuit electric power comprising a fixed contact 14 and a tilting contact 15, connected respectively to terminals 16 and 17 mounted on faces of the housing.
  • the tilting contact 15 is integral with a contact arm 18 which is articulated at a point 19 on one end of a rigid conductor 20, the other end of which is connected to the terminal 17.
  • a spring 21 keeps the arm in abutment against the rigid conductor so to guarantee the functioning of the articulation of the two elements in point 19.
  • the electromagnet is of conventional type as described for example in the application French cited in the preamble. It is associated with a pallet 22 which cooperates with a return spring 23 to urge the latter into the position shown in solid lines, that is to say that which corresponds to the closing of the contacts 14 and 15.
  • the control mechanism 13 mainly comprises a balance 24 and a link 25 articulated at one of its ends on the pallet 22 and at its other end on the pendulum 24.
  • the point of attachment of the link 25 to the pendulum 24 may have two positions 25a and 25b respectively, which are arranged on either side of a fixed axis 26 around which the pendulum pivots.
  • the point of attachment is the point 25a, whereas in the two other intended uses, respectively described with reference to the figures 2 and 3, the attachment point is point 25b.
  • the balance comprises a central recess 27 in which one end is engaged of the contact arm 18 which is moved from its position shown in solid lines towards its position 18 ′ shown in broken lines, by a spout 28a of the pendulum 24 and conversely by a spout 28b of this same pendulum.
  • the pallet 22 When the electromagnet is activated, the pallet 22 is attracted by the pole surface 29.
  • the link 25 moves to its position 25 '(shown in broken lines) and swings the balance 24 to its 24 'position (also shown in lines interrupted).
  • the latter acts on the contact arm 18 to bring it into 18 ', which has the effect of moving the tilting contact 15 into its position 15 '(shown in broken lines).
  • a spiral spring 30 can be provided with end branches 30a and 30b, one of which bears against the end of the connecting rod 25 at the attachment point 25a and the other of which is in abutment against a fixed stop 30c.
  • a contactor is the opposite of a breaker, that is to say that when the electromagnet is not activated, contacts 14 and 15 are open.
  • An activation pulse sent to the electromagnet causes the closure of contacts 14 and 15.
  • This operation in contactor is obtained by the fact that the link 25 is, in this case, attached to the balance 24 at point 25b and no longer at point 25a.
  • the moving parts of this together are shown in solid lines in their position corresponding to the closing of the contacts 14 and 15, that is to say when the electromagnet is activated.
  • These elements are represented in broken lines in their function corresponding to the opening of contacts 14 and 15, that is to say when the electromagnet is not activated.
  • the apparatus is used as an inverter. It differs in this case of the preceding apparatuses in that it comprises an additional terminal 40 which is electrically coupled to a complementary fixed contact 41 arranged for cooperate with the rocking contact 15.
  • this rocking contact includes a first contact element 15a arranged to cooperate with the fixed contact 14 and a second contact element 15b arranged to cooperate with the fixed contact complementary 41.
  • the contact 15 was produced in the same way, that is to say that it comprises the two contact elements 15a and 15b, but only element 15a is active when the device is used as breaker or as a contactor.
  • each position of the pallet corresponds to the closing of a of the two circuits respectively connected between terminals 16 and 17 or 17 and 40.
  • the moving elements When the electromagnet is activated, the moving elements occupy the position shown in solid lines and the contacts 14 and 15 are closed.
  • the electromagnet When the electromagnet is not activated, the moving elements occupy the position shown in broken lines and contacts 15 and 41 are closed.
