Definitions

  • the present invention relates to an electromagnetic switch device in particular a contactor, comprising, in an envelope consisting of a base and a housing isolation, a contact carrier in which are housed contact bridges and comprising a movable lock capable of immobilizing the contact carrier.
  • the contactors are fitted with a contact carrier provided with contact bridges establishing or cutting the current when this contact carrier is moved by the moving parts of an electromagnet.
  • This patent application DE 43 41 330 discloses a switch device comprising a contact door latch provided with a stop which cooperates with a stop of the bow case and is subjected to a spring.
  • the stopper is released and the spring can move the latch from the rest position to the latch position. It is nevertheless possible to remove the case although the lock is seized and cannot come lock the contact holder.
  • the contactor is soldered, the single ramp system allows to remove the case while the poles are established.
  • the object of the present invention is to ensure the locking of the contact carrier by removal of the isolation box, during a disassembly, this positively and with high security, without special handling. Safety is ensured even after a bonding of contacts.
  • the device according to the invention is characterized in that the lock and the housing insulation have sliding assembly means positively displacing the latch the rest position towards the contact carrier in the locked position by moving away from the housing isolation from the base and sliding assembly means positively moving the contact carrier lock, from the locked position, by bringing the housing closer towards the base.
  • the sliding lock has a mortise forming two slides inclined with respect to the translation plane of the contact carrier and the isolation box has a tenon forming two inclined ramps in the mortise when mounting the housing insulation on the base, the axis of this tenon also being inclined relative to the plane of translation.
  • the lock is guided near a partition limiting two arc chambers and parallel to it, between two contact bridges.
  • the contactor illustrated in the drawings comprises an envelope consisting of a base 1 which can be fixed on a support (rail, plate) and an isolation box 7 which can be made up of two parts.
  • a base 1 which can be fixed on a support (rail, plate) and an isolation box 7 which can be made up of two parts.
  • an electromagnet 2 having a fixed yoke 21, a coil 22 and a movable armature 23.
  • the latter is connected to the lower part of a contact carrier 3 which is guided in the isolation box 7 and in the base 1 according to a plane PP '.
  • the upper part of the contact carrier carries several contact bridges 4.
  • Each contact bridge 4 is provided with movable contacts 41 which cooperate with fixed contacts 51 mounted on connection terminals 5 to form a pole of power 6 in a breaking chamber 71 of the isolation box 7.
  • the latter is fixed from in the conventional way, using assembly screws, to the base 1.
  • the contact carrier 3 is constituted by columns 33 connected by the walls in are formed grooves which slide on partitions 72 of the isolation box. These partitions 72 serve to isolate the arc chambers 71 from each other to others.
  • a window in which houses a contact bridge 4 and a spring associated therewith.
  • the contactor comprises a sliding lock 8 which is guided in the base 1, at proximity of a partition 72 limiting two arc chambers and between two contact bridges 4.
  • the guide direction of the latch 8 is parallel to the partition 72 and perpendicular to the plane P-P 'of translation of the contact carrier.
  • the end of this lock can engage under a pin 31 of the contact carrier 3 so as to immobilize the latter.
  • This pin 31 is disposed between two columns 33.
  • the lock 8 is subjected to a spring 82 which tends to push it towards the contact carrier 3.
  • This lock 8 has a mortise 81 forming two slides 84, 85 inclined along Q-Q 'relative to the plane (P-P') of translation of the contact carrier.
  • the isolation box 7 has a pin 73 forming two inclined ramps 74 and 75 sliding respectively against the slides 84 and 85 of the mortise 81 when the isolation box 7 on the base 1.
  • the axis and the ramps 74 and 75 of the post are inclined according to Q-Q ' with respect to the translation plane P-P '.
  • the tenon 73 is mounted on one side, projecting, from a partition 72 of the housing Isolation 7. It fits into the mortise 81 when the isolation box 7 is assembled to the base and move aside the contact carrier lock 3. When the housing 7 is removed and the post 73 emerges from the mortise 81, this tenon by lifting moves the latch 8 towards the contact carrier 3.
  • the top of the tenon 31 has an inclined ramp 32 which makes it possible to separate the latch 8 when raising the contact carrier, from the closed contacts position.
  • the lock has, on the side of the contact carrier, an inclined chamfer 83 which cooperates with the inclined ramp 32.
  • the housing 7 can be removed to allow the user to manually separate the contacts.
  • the contact carrier 3 thus released can go back up.
  • the inclined ramp 32 pushes the sliding lock 8 which can then engage under the tenon 31, without the need to replace the housing 7.
  • the double ramp one of which acts by locking the contact holder when remove the case and the other one unlocks the contact carrier when it is replaced, the security is ensured in all cases.
  • the springs only serve to maintain the position of locking.
