Definitions

  • the present invention relates to a multi-pole electrical switch device with low voltage comprising a housing which includes current conductors internal, a face near which extend parallel distribution conductors located substantially in a common plane and connection screw terminals of power likely to be connected to distribution conductors to connect these to connection pads of the internal current conductors.
  • the invention aims to solve this problem.
  • the screw terminals are of the piercing type of insulation and comprise a cage housing a connection pad, cooperating with a piece of clamping and provided with an active passage for the distribution conductor associated with connect, the cages being substantially aligned with the common plane of the conductors distribution, at least one of the cages having at least one passage passive for distribution conductors to be connected to the other terminals.
  • the cages are of stepped shape and comprise at one end a screw and at the other end the active passage of the associated distribution conductor, the screws of the different cages being located at the same level and the active passages being located at staggered levels, and between these ends a middle part presenting the passive passages and of height differentiated according to the cages; insulation piercing prongs are preferably provided on the parts tightening and these have a different length depending on the terminals.
  • the cage is advantageously mobile, while the clamping piece is fixed and wedged against the connection pad, and a bypass conductor can be inserted and clamped between a screw clamp and the connection range.
  • the screw terminals are advantageously housed in a removable terminal block in block of connection pads and comprising a body and a sole, the sole carrying for each terminal a clamping piece provided with clearance claws of insulation and having passages through which the connection pads pass.
  • the electrical device shown in the figures is a multi-pole switch device of the contactor, circuit breaker or contactor-circuit breaker type comprising a box 10 which has a front face 11 provided with a control button, one face upper 12, side faces 13,14 and a rear face 15 used for fixing on a support not shown.
  • a box 10 which has a front face 11 provided with a control button, one face upper 12, side faces 13,14 and a rear face 15 used for fixing on a support not shown.
  • the housing 10 are located internal conductors and mechanical and electrical control and / or protection members.
  • the device being here three-pole, the internal conductors end in three connection pads A1, A2, A3, here in the form of tabs projecting from one face of the housing, for example at its upper face 12.
  • the conductors are flexible cables; they can also be formed by conductors rigid.
  • a bomier 20 ensuring the connection of the distribution conductors C1, C2, C3 with the connection lugs A1, A2, A3 is assembled to the device on its face 12.
  • This bomier comprises an insulating housing consisting of a body or cover 21 and a sole 22; the housing houses screw terminals with insulation piercing B1, B2, B3, these terminals being somehow stepped.
  • Each terminal B is a power connection terminal and includes a cage clamp 30 movable in translation in a direction Y perpendicular to X in response to the rotation of a screw 31 engaged in a threaded orifice 32 of the cage and a clamping piece 40 with claws 43 fixedly mounted on the sole 22.
  • the screws 31 of the three terminals are identical and located on the same level to facilitate maneuvering by the operator, while the cages 30 and the clamping pieces 40 are of differentiated length in the Y direction.
  • claws can be carried by the cage.
  • the cage 30B1 of terminal B1 is the shortest, the cage 30B2 of terminal B2 has a medium length and the 30B3 cage is the longest.
  • Each cage 30 has a section straight substantially U-shaped and forms a cradle for the cable to connect; each cage includes a front face 33 provided with the threaded orifice 32, two cheeks 34 provided at their end 35 opposite the screw with an active passage 36 for the cable to be connected in this terminal and, for terminals 30B2 and 30B3 and in a median part of differentiated length 37, at least one passive passage, preferably an oblong passive passage 38, for the cables of the other terminals, respectively C1 for 30B2 and C1, C2 for 30B3.
  • the active passages 36 are located therefore in positions offset in direction Y.
  • Passages 36.38 are open upwards opposite side 12, so that the cables can be engaged in transverse corridors 23 of the body 21 and in the passages considered.
  • Each passage 36 is bordered towards the rear by an active stop 36a tightening and forward by a stop 36b active in loosening.
  • Each cage 30 further comprises towards the face 12 an opening 39 for leaving pass the associated connection tab A, which itself crosses a light 24 of the sole 22.
  • a removable or pivoting cover can also be added to the body to cover the cables to the right of the device.
  • Each clamping piece 40B1, B2, B3 has a U-shaped cross section and includes two lateral faces 41 guided against the internal faces of the cheeks 34 of the associated cage and, at the front end, a bearing face or bearing heels 42 allowing to wedge against the rear face of the respective connection pad A1, A2, A3.
  • the lateral faces 41 are of different lengths for the various parts 40; they end at their rear end with the claws themselves 43 and are connected together by a lower face 44 provided with two orifices; these holes are intended to engage on pins 46 of the sole 22 to position on the latter, Exhibit 40.
  • the body 21 of the connection box has a front face 25 provided with orifices 25a passage for a screwdriver, an upper face 26 provided with a share of corridors 23 already mentioned and on the other hand openings 26a for the introduction in the branch cable terminals, these cables can be clamped directly between the movable brackets 31a and the connection pads A1, A2, A3.
  • the body 21 finally has surfaces 27 forming front and rear stops for the inter-house cages and partitions or other various forms 28 constituting slides for cages.
  • the body 21 is assembled to the sole 22 and the connection box is assembled to the housing of the device by any usual fixing means allowing disassembly.
  • the wiring of the terminals is carried out as follows. We assume that the bounds B are installed in the connection box, with the clamping parts 40 positioned on the pins 46 and the cages 30 held by the sole 22, the stops 29, the front face 27 and the partitions 28.
  • the cables C are introduced into the corridors 23, then the screws 31 are actuated; each screw moves until taken of its stirrup 31a against the connection pads A1, A2, A3, and then attracts the cage 30 which drives the cable associated with the contact of the claws 43 of the part 40, itself wedged against track A, until the cable sheath is pierced and the contact between the claws and the cable core.
  • the cage stroke is short, so that the cable only undergoes a displacement minimal in direction Y.
  • you want to connect cables to the device bypass they are introduced into the holes 26a and tightened by the front stirrups training cages.
  • the cables are free claws 43 thanks to the stops 36b of the cages 30.
  • the connection box 21,22 can easily be removed from the device as a whole with C cables without it being need to disconnect them.
