Definitions

  • the present invention relates to an electromagnetic control switch device composed of two identical switch devices grouped one beside the other and each having a contact carrier slide, movable in translation and provided with a contact finger, these two switch devices being coupled to each other by a locking or mechanical locking device capable of preventing simultaneous movement of the two movable slides, said mechanical locking device being capped by a cover.
  • the mechanical locking module is superimposed on the block contactors and increases the height of the assembly.
  • add-on blocks When mounting add-on blocks, these add-on blocks must be fixed on the locking module and when you want to dismantle them, you exert a direct force on the locking module at the risk of separating it from the contactor-blocks on which it is fixed.
  • the height of the device is modified depending on whether or not the locking module is mounted.
  • Patent DE-A-21 14 509 comprises two switching devices connected to each other by a device for mechanical lock located on top of the devices.
  • the switchgear and the locking device are fitted using a cover.
  • the disadvantages are that, to extract the locking device, it is necessary to separate the two switch devices by removing the cover, and in that the addition of this device has the result of increasing the height of the devices.
  • the present invention proposes to provide a switching device composed of two elementary switching devices and in which the mechanical locking device or module is embedded in the elementary switching devices. This embedding has the result of not increasing the size or height of the entire device equipped with the locking module.
  • the invention makes it possible to avoid that the additive blocks are in direct engagement with the locking module and allows a direct drive of these additive blocks.
  • the additive blocks are fixed on the cover of the device, whether the mechanical locking module is incorporated in the device or not.
  • the dismantling of the add-on blocks does not exert any direct effort on the locking module.
  • the height of the device does not change depending on whether or not the locking module is mounted.
  • the locking module can be added or removed without having to dismantle the basic switchgear.
  • each of the switch devices has a central embedding channel which extends in hollow relative to the front face of the housing between the cells in which the terminals are housed and in which the mechanical locking device is embedded, so that the latter can be embedded or extracted without dismantling the switch devices.
  • the locking device comprises two coupling rods coupled to the contactor fingers and articulated to a cam balance cooperating with a fixed stop pin.
  • the cover is provided with lights allowing the deflections of the fingers of contactor so as to allow the coupling of the contactor fingers with additive blocks.
  • the locking device comprises a support plate ensuring the guiding in translation of the coupling rods.
  • the ends of the contactor fingers which pass through the openings in the cover covering the locking device and the front face of the switching devices and into the openings for driving the coupling rods.
  • the locking device is mounted below the cover, the latter comprising guide means for the coupling rods.
  • An electromagnetic control switch device of the inverter type as illustrated in the drawings comprises a first switch device 1 and a second switch device 2, identical and grouped one next to the other. These switching devices are block contactors or power relays.
  • the devices 1 and 2 are block contactors.
  • Each block contactor 1 or 2 comprises a molded insulating housing 11 or 21 containing a plurality of poles.
  • This housing 11 or 21 has cells 12, 13 or 22, 23 in which are housed the connection terminals connected to contacts.
  • the front faces of the block contactors 1 and 2 are marked 16 and 26 respectively, while the rear faces are marked 17 and 27 respectively.
  • Each of the rear faces has clipping means such as 18 for clipping the contactor-block on a rail.
  • each of the housings In a chamber of each of the housings is housed, in a manner known per se, a movable contact-carrying slide carrying movable bridges provided with the contacts mobile.
  • This contact carrier slide is guided in a housing of the housing so as to move in a direction perpendicular to the surface of the contacts between an open position and a closed position, parallel to the rear face 17 or 27 of the block contactor.
  • This slide has, in a manner known per se, compression springs for the movable contacts on the fixed contacts.
  • the contact carrier slide can slide in its chamber under the action of an electromagnet in the guide direction defined above.
  • Each of the housings 11 or 21 has a central embedding channel 15 or 25 extending in hollow relative to the front face 16 or 26 respectively, between the cells.
  • Each channel 15 or 25 has a substantially rectangular section and is delimited by lateral faces, parallel and perpendicular to the front face 16 or 26 and by a bottom 19 or 29.
  • Each of these channels extends parallel to the direction of translation of the Corresponding contact slide.
  • Each contact carrier slide has a contact finger 14 or 24 which projects from the bottom 19 or 29 respectively of the corresponding channel 15 or 25. This contact finger 14 or 24 can move in translation according to the longitudinal axis of the central channel.
  • Each central embedding channel 15 or 25 is open at least on the side of a side face of the contactor housing.
  • Projections such as 191 or 291 are provided in the channels, in relief with respect to the bottoms 19 and 29.
  • the wall forming one or the other of the embedding channels 15 or 25 is in one piece without any longitudinal joint plane. Each channel 15 or 25 extends over the entire width of the device.
  • the mechanical locking device identified 4 as a whole is composed of a first coupling link 41, a second coupling link 42 and a cam balance 43 cooperating with a fixed stop pin 45.
  • the coupling rod 41 has, at one of its ends, a driving light 411 in which the end of the contact finger 14 engages so as to form a positive connection between rod and lever.
  • the link 41 has a pin 412 engaging in an articulation housing 432 of the cam-balance 43, so as to produce an articulation.
  • the coupling rod 42 has at one of its ends a driving light 421 in which the end of the contact finger 24 engages so as to form a positive connection between rod and lever.
  • the link 42 has a pin 422 engaging in an articulation housing 43 of the cam balance 43, so as to produce an articulation between said rod and said balance.
  • the articulation axes 412 and 422 are perpendicular to the front face of the block contactors.
  • the cam balance 43 has a heart cam formed by two ramps 433 and 434 and cooperates with a pin 45 secured to the support plate 44.
  • the locking device 4 fits into the embedding channels 15 and 25, the links 41 and 42 being engaged on the fingers 14 and 24.
  • a cover 3 covers the front faces of the block contactors.
  • the housings 11 and 21 do not have any part or part of the housing permanently arranged to retain the locking device in a direction perpendicular to the front faces of the devices.
  • the projections 191 and 291 of the housing serve to immobilize the module 4 in the direction parallel to the longitudinal axis of the channels.
  • the locking device comprises a support plate 44 on which the connecting rods 41 and 42 and the central balance 43 are mounted.
  • This plate has rectilinear slides 441 serving to guide in translation the coupling rod 41 and rectilinear slides 442 serving in guiding in translation of the coupling rod 42.
  • the plate has two slots 443 and 444 through which the ends of the operating levers 14 and 24 pass. These slots 443 and 444 are respectively arranged opposite the slots 411 and 421 of the link rods. Holes 445 and 446 are provided in the support plate 44 to serve as a housing for the projections 191 and 291.
  • the cover 3 has two openings 31 and 32 allowing passage of the ends of the contactor fingers 14 and 24 respectively. These two lights are provided vis-à-vis the lights of the plate 44 and the lights of the coupling rods. The lights 443, 444 of the support plate 44 and the lights 31 and 32 of the cover 3 allow the translational movements of the fingers 14 and 24.
  • the locking device 4 is housed under the cover 3 and the contactor fingers 14 and 24 crossing the aligned lights 411, 443 and 31 on the one hand, 421, 444 and 32 on the other hand.
  • the mechanical locking device 4 is independent of the cover 3 which is capable of covering the front faces of the block contactors 1 and 2.
