Definitions

  • the present invention relates to an auxiliary block in particular for signaling the state of circuit breakers as described in the preamble of claim 1 (DE-A-2 910 389).
  • auxiliary blocks coupled laterally to a set of circuit breakers joined by their side faces, said blocks being used for example to control the state circuit breakers or detect the presence of a fault in their operation (overcurrent, short circuits etc ).
  • These auxiliary blocks are constituted, in their form the more generally, by a one-piece housing comprising on the one hand, so-called auxiliary contacts controlled by the circuit breaker mechanism and electrically connected by studs connection provided in one side of the housing, to a sign board, while the opposite side of the housing has a recess intended to allow the passage of one or several teeth of a distribution comb ensuring the supply of circuit breakers.
  • the comb connection is made upstream or downstream of circuit breakers depending on the country in which these circuit breakers are intended to be used. It follows that it is necessary to have two types of auxiliary blocks allowing respectively a mounting of the comb downstream or upstream of the circuit breakers.
  • the present invention solves this problem and proposes an auxiliary block, in particular for circuit breaker status indication, simple in design and can also be used good for mounting upstream or downstream of the comb for the purpose of standardization increased.
  • the subject of the present invention is an auxiliary block, in particular for signaling.
  • the state of a circuit breaker intended to be coupled and attached laterally to a block circuit breaker
  • said auxiliary unit being formed by a housing containing contacts auxiliaries mechanically controlled by the mechanism of the circuit breaker block, and connected electrically to connection terminals arranged on one side of the case, while the opposite side of the housing has a recess intended to allow the passage of one or several teeth of a distribution comb ensuring the electrical supply of the block circuit breaker
  • this block being characterized in that the housing is equipped with two parts separate comprising a main part fixed to the circuit breaker block and containing the auxiliary contacts, and a second connection part comprising studs connection of the auxiliary contacts and said recess, and in that the second part is swivel mounted on the main part in two different positions allowing respectively mounting the distribution comb upstream or downstream of the block circuit breaker.
  • connection part of so that the recess in said part is opposite the comb.
  • connection part is mounted rotating about an axis substantially perpendicular to the plane of the teeth of the comb, the passage from one of the aforementioned positions to the other taking place by a 180 ° rotation of the connection part around said axis.
  • connection part comprises a housing intended to receive the lower part of conjugate form of the main part, around which the connection part is rotatably mounted.
  • the main part and the connection part comprise means for limiting the rotational stroke of the connection part to 180 °.
  • the main part has a groove in which is introduced and fixed part of conjugate form of the connecting part.
  • connection pads are connected to the contacts aforementioned auxiliaries by means of conducting wires passing through two orifices provided respectively in the connection part and the main part.
  • the pads are connected to the auxiliary contacts by through friction contacts provided on either side of the main part cooperating with conductive elements connected to the aforementioned studs.
  • the block has three connection pads and three auxiliary contacts forming an inverter.
  • the main part comprises a shape part substantially parallelepipedic and two arms extending perpendicular to the faces lateral of said parallelepiped part, said arms bearing respectively on a C-shaped part or an opposite stepped part housing the connection pads of the connection part.
  • auxiliary block B attached by one of its side faces to a block circuit breaker 1 formed by several circuit breakers 1a, 1b, 1c coupled laterally and supplied by a distribution comb 7 connected to a three-phase busbar (not represented).
  • This auxiliary block B is of the type of blocks used to control the state opening or closing circuit breakers or detecting a fault such as a overcurrent or a short circuit.
  • the auxiliary block B is formed by a housing 2 consisting of two parts separate parts called main part 8 and connecting part 9 respectively.
  • main 8 comprises a substantially parallelepiped part 22 and two arms 23, 24 extending perpendicular to the side walls of this part 22.
  • the part of connection 9 is formed of a substantially C-shaped side portion 25, of a portion opposite lateral step 26 and of a connecting part 27 of these last two parts 25, 26.
  • the internal walls of these lateral 25, 26 and connecting 27 parts form a housing 11 for the lower part 12 of the aforementioned main part 8, the two arms 23, 24 come to bear respectively on the upper faces of the abovementioned lateral parts 25, 26.
  • the main part 8 comprises three so-called auxiliary contacts 3 forming a change-over, these three contacts 3a, 3b, 3c being connected on the one hand mechanically to the mechanism of the circuit breakers with which auxiliary block B is associated, and on the other hand, through conductor wires 13, 30 respectively to three connection pads 4 placed inside the aforementioned stepped side portion 26 of the connection portion 9, said pads 4 being intended to be electrically connected to a signaling panel (not shown) connected by example at a control desk.
  • the C-shaped side part 25 of the part of connection 9, opposite the stepped side portion 26, has a recess 10 intended for allow the passage of the teeth 7a of the distribution comb 7.
  • connection part 9 is rotatably mounted by appropriate means, around the main part 8, and around an axis X substantially perpendicular to the plane P of the teeth 7a of the above-mentioned comb 7.
  • auxiliary contacts 3 are connected to the connection pads 4 by conductive wires 13 passing through two orifices 15, 14 provided respectively in the lower wall of the main part 8 and the upper wall of the connecting part 27 of the connecting part 9.
  • the main part 8 has on one of its sides, a lug 39 intended to come into contact against two opposite stops 30, 31 formed in the connection part 9, during the rotation of the connection part 9 around the main part 8. These two stops 30, 31 make it possible to limit the rotation stroke of the connection part 9 to 180 ° so avoid shearing of the conductive wires 13.
  • the three studs aforementioned connections 4 are connected to the three auxiliary contacts 3 by three so-called contacts rubbing.
  • Three contact pads 16 to 18 and 19 to 21 are thus provided on either side of the main part 8.
  • the three contact pads 16 to 18 and 19 to 21 located on each side are connected respectively by three conductive wires 31a, 31b, 31c and 31d, 31e, 31f, to three auxiliary contacts 3a, 3b, 3c.
  • the connecting part 29 is mounted on the main part 28 so as to be able to be turned over and thus allow mounting of the comb 7 upstream or downstream of the circuit breakers.
  • the main part 28 comprises a part parallelepipedic 22 and two arms 23, 24, the parallelepipedic part 22 comprising a groove 28a in which is fixed, by appropriate means, a so-called connecting part 29a connecting the C-shaped part 25 and the stepped part 26 of a connecting part 29 such as that described above.
  • the connection of pads 4 to auxiliary contacts 3 although not illustrated in these figures, could be produced for example by means of conductive wires passing through two orifices provided in the main part and the connection part, or by means of friction contacts such as those described previously.
  • connection part (8, 28) is briefly described below on the part main (9, 29) for the various embodiments of the invention.
  • the passage of the connection part 9 from one position to another will be done in the same way as for the previous embodiment.
  • the pads 4 are electrically connected to the contact pads 16 to 18, which allows mounting upstream of the distribution comb 7.
  • the pads 4 will be connected electrically to the contact pads 19 to 21, which will allow mounting of the comb 7 in downstream.
  • the rotation stroke is not limited to 180 °, this being from to fact that the conductive wires 13 are not likely to be sheared, as is the case in the realization previously described.
  • two successive 180 ° rotations in the same direction, of the connection part 9, can be operated.
  • an auxiliary block has therefore been produced, in particular for signaling the state a circuit breaker, of simple design, which can be used in many countries since it allows mounting of the distribution comb both upstream and downstream of the circuit breakers.
