Definitions

  • the present invention relates to a single-pole or multi-pole electrical protection switch comprising for each pole a housing provided with a coupling piece to the neighboring pole or to a juxtaposable additive device.
  • Such coupling is used to transmit from one pole to another, or from one pole to a neighboring device, a mechanical signal for the purpose of triggering and / or signaling in the event of a fault or following an operation. voluntary.
  • Such known multipolar devices generally require, to ensure coupling between the poles, a part or more coupling parts which must be attached by fitting or insertion on or in transmission parts belonging to the triggering mechanisms of the various poles.
  • the object of the invention is in particular to simplify the design and mounting of a protective switch device with couplable poles by using a minimum number of component parts' suitable both for a single-pole version and for different multi-pole versions.
  • a single-pole or multi-pole electrical protection switch comprising for each pole a prismatic insulating envelope provided with two lateral partitions, the first lateral partition forming part of an open housing, the second lateral partition belonging to a closing element attached to the housing for close the envelope, each plane of symmetry of a pole being separated from that of a neighboring pole by a distance called pole distance, each pole comprising a trigger mechanism with which is associated a movable transmission part in response to an actuation, the transmission part cooperating with a coupling part of said pole with a neighboring pole.
  • the transmission part and the coupling part form a single part arranged for rotation in a bearing formed in the lateral partition of the housing and with an axis perpendicular to said partition, the coupling part having at first end a male coupling element and at a second end a female coupling element, these coupling elements being of complementary shapes to allow cooperation by direct interlocking of adjacent and coaxial coupling parts;
  • the polar housing is in the form of a bowl housing the trigger mechanism and the coupling part.
  • the protective switch can thus be produced with a small number of constituent parts, namely a polar box forming a bowl which contains the trigger mechanism and its combined transmission and coupling part, intermediate polar boxes of a single type forming as many bowls which contain the triggering mechanisms of the successive poles, and a cover for closing the bowl of the last pole.
  • the assembly of the protective switch is facilitated by the stacking of polar cuvettes of low height and substantially identical, easy to store and to handle manually or automatically.
  • each pole box is equipped with its coupling piece before stacking the next pole box, because its coupling piece is part of its own mechanism for triggering or opening the contacts.
  • the part or the coupling parts do not protrude outside the side partitions of the unipolar or respectively multipolar envelope, and that the male coupling element of a first coupling part is housed in a recess a side wall of the envelope, the dimensions of the recess allowing the housing therein of the female coupling element of a second coupling part, coaxial and adjacent to the first.
  • the recess is preferably bordered by at at least one bearing surface perpendicular to the axis of the coupling parts to receive a corresponding support collar provided on at least one of the coupling parts.
  • the total width of the switch housing is expected to be slightly greater than a multiple of the pole pitch and the length of each coupling piece is slightly greater than the pole pitch.
  • the switch illustrated in Figure 1 is three-pole; each of the poles P1, P2, P3 includes separable contacts in the event of detection of an electrical fault or in the event of voluntary operation.
  • the triggering and operating mechanisms have not been indicated for the sake of clarity.
  • the switch housing includes for the pole P1 an insulating pole-shaped housing A and for the poles P2 and P3 insulating pole boxes also in shape.
  • bowl B the housing of pole P3 being closed by an insulating cover C; we understand that it is thus associated with each pole a closed prismatic envelope constituted on the one hand, by a bowl A or B and, on the other hand, as the case may be by the bottom of an adjacent bowl or by the cover C.
  • the partitions of the bowl bottoms A, B and the partition of the cover C have thicknesses denoted e A , e B , e C respectively .
  • the polar housing B differs slightly from the polar housing A in that it has nesting conformations D, while the outer wall of the housing A is smooth.
  • the switch housing has elements (not shown) of attachment to a support such as a rail E or a perforated plate. The mutual fixing of the elements A, B, C is carried out for example by riveting.
  • FIG. 1 shows the planes Yl-Y1, Y2-Y2, Y3-Y3 of symmetry for the terminals and the separable contacts of the poles Pl-P3, these planes being distant from each other by the polar pitch P.
  • each polar envelope is housed a combined transmission and coupling part 10.
  • the parts 10 are identical and arranged coaxially along an axis X-X perpendicular to the planes Y-Y.
  • Each part 10 is part of the trigger mechanism of the respective pole; it is rotatably mounted in a bearing 11 formed in a side wall or partition 12A, 12B, 12C and it has at its first end 13 a male coupling element 14 and at its second end 15 a female coupling element 16 in which s 'fits the male element 14 of the adjacent coupling part.
  • Each coupling end 10 emerges in a recess 17 formed in the wall 12A, 12B, 12C.
  • the recess 17 is bordered by at least one bearing surface 18 perpendicular to the axis XX to receive a corresponding support flange 19 of the part 10.
  • Such support surfaces and flanges can be provided at the two ends of the part 10.
  • the coupling piece 10 has a length 1 which is less than the width L1 (or L2 or L3) of the corresponding polar envelope, but which is greater than the polar pitch P by a value at most equal to x, for example slightly lower by a set j to x. In this way, the coupling pieces 10 of adjacent poles fit together at a depth (x-j) without requiring additional pieces and without protruding from the external walls 12A and 12C to the left and to the right of the switch.
  • FIG. 3 shows a three-pole protection switch which comprises a first column of pivoting coupling pieces 10 coaxial with axis Xl-Xl and a second column of pivoting coupling pieces 20 with coaxial axis X2-X2 parallel to Xl- Xl.
  • Each part 10 is biased by a fault, magnetic and / or thermal tripping means, to act on a contact carrier 30 pivoting in the Y-Y plane via an intermediate actuating part 31; we see that the part 10 is part of the actuation mechanism of the pole considered.
  • One of the parts 20 can be called up by means of voluntary opening of the contacts and resetting to act on the contact carrier 30 of the pole concerned.
  • the rotary movement of the part 20 is transmitted to a neighboring part 20.
  • the centerpiece 20 belongs to the central pole P2, it controls the slave parts 20 of the side poles P1, P3.
  • the parts 20 are identical to each other and they offer in particular the same characteristics of conformation and length.
  • the recesses 17 associated with the parts 10 and the homologous recesses 32 associated with the parts 20 pass through when they are arranged in the internal partitions 12B of the switch. They can be either through ( Figure 1) or blind and delimited by knockouts (Figure 3), to allow coupling to an additive juxtaposable to the switch when they are formed in the external partitions 12A, 12C of l 'light switch.
  • the arrangement adopted for the couplable pole switch requires a minimum number of parts suitable for both the unipolar version and the various multipolar versions: cup A, cup B, cover C, coupling piece 10 for the automatic release and coupling part 20 for voluntary control and reset, without additional connecting parts.
  • each pole box has an open front face
  • a cover whose width is substantially that of the stack.
  • This cover can therefore completely cover the open and projecting front part of the poles; moreover, it supports the voluntary opening and resetting means, for example the switch control button.
  • the polar pitch is preferably a fraction of a normalized width, this fraction being equal to the ratio of two whole numbers chosen so as to make it possible to obtain, whatever the number of poles, a composition of modular devices whose width will be equal to a multiple of the standard width or, in the least favorable cases, will exceed the said multiple by an amount equal to half the standard width.
  • W 9 mm
  • W 9 mm
  • the total width of the switch housing is much greater by a standard half-width 2 than an appropriate multiple of the pole pitch.
  • the total width of a box with n poles can alternatively be greater by a standard width W than n times the pole pitch.
