Definitions

  • the invention relates to a multi-pole electric circuit breaker, in particular with a molded case, having a circuit breaker block for housing the breaking contacts and for the mechanism for controlling said contacts and a removable trip block for housing the associated thermal and / or magnetic trip elements.
  • said trip unit comprising for each pole a section of power conductor electrically connected in series by a disconnectable connection to an associated section of conductor of the circuit breaker block containing the breaking contacts, said trip elements reacting to overcurrents and short circuits of currents flowing through said conductors.
  • the object of the present invention is to remedy these drawbacks and to allow the production of a circuit breaker with an easily removable trip unit and with reduced overall dimensions.
  • the circuit breaker according to the invention is characterized in that the disconnectable connection of each conductor has a connection area making an acute angle with the general direction of said conductors in the circuit breaker.
  • connection pads allow an oblique arrangement of the clamping screws and the screw access holes which are perpendicular to the pads. These screws no longer open on the front face of the circuit breaker crossing the entire height of the box, but on the side face carrying the connection terminals. This reduces the overall length at the expense of the overall height, but the space available in this area is sufficient to accommodate the inclined areas under the mechanism of the trigger block.
  • Claims 2 to 9 relate to particular embodiments of the subject-matter of claim 1.
  • connection screws advantageously simultaneously secure the trip unit block on the circuit breaker block, the connection pads of one of the blocks being resiliently mounted to compensate for positioning faults and allow good contact of the pads of the three poles of the circuit breaker .
  • the inclined pads are arranged in the lower part of the trigger block to facilitate access to these screws and ensure good fixing of the block.
  • the section of conductor associated with the trip unit is folded in a loop to cross the magnetic circuit of the electromagnetic trip device and ends with the inclined connection area located below this magnetic circuit. This range comes into contact with the associated range carried by the base of the circuit breaker block when the trip unit is put in place. The connection area is thus transferred under the trip unit and the electrodynamic forces generated in the loop increase the contact pressure of the pads.
  • a multipole circuit breaker 10 with molded housing for example a three-phase circuit breaker, is constituted by the assembly of a circuit breaker block 12 and a trip block 14 on a base 16 belonging to the circuit breaker block 12.
  • the base 16 carries the connection terminals 18, 20 for input and output of the circuit breaker, capped by removable terminal covers 22, 24.
  • the circuit breaker of generally parallelepipedal shape is provided, on its front face 26 opposite the base 16, with a control lever 28.
  • circuit breaker block 12 In the circuit breaker block 12 are housed the three pairs of separable contacts 30, 32 as well as the control mechanism 34, which causes the displacement of the movable contacts 30 in the open and closed position during an operation manual operation of the lever 28 and automatic opening on a triggering order of a bar 35 of the trigger block 14.
  • the mechanism 34 and the connections between this mechanism 34 and the movable contacts 30 and the trigger block 14 are shown sc hematically in fig. 1, such devices being well known to specialists.
  • each pole is inserted in a power conductor 36 which extends between the terminals 18, 20 along the base 16 crossing the trip unit 14, which contains for each pole a thermal trip device 38 and a trip device electromagnetic 40 causing tripping of the circuit breaker respectively in the event of overload and short-circuit.
  • the trip unit 14 is removable and on the same circuit breaker unit can be mounted any one of a range of trip units with different characteristics.
  • the terminals or pads 18 are integral with the trip unit 14 and removed with the latter during disassembly.
  • Each conductor 36 has a connection 42, disconnectable in the junction area of the circuit breaker block 12 and the trip block 14, which is broken by the removal of the trip block 14.
  • Such circuit breakers are well known and it is unnecessary to describe them more in detail.
  • the disconnectable connections 42 are arranged in the lower part of the trip unit 14 and each comprises a connection area 44 inclined, for example by an angle close to 45 ° with the general direction of the conductor 36, that is ie from the base 16.
  • the pad 44 belongs to the circuit breaker block 12, or more exactly it is mounted floating on this block by being connected by a braid 46 to the movable contact 30.
  • On the pad 44 is tightened, in the mounted position of the trigger block 14, the end 48 of the section 50 of the conductor 36 passing through the trigger block 14.
  • the opposite end of the section 50 is connected to the terminal 18 and the section 50 extends inside the trigger block 14 according to a loop path through a U-shaped yoke 52 of the magnetic circuit of the electromagnetic trip device 40.
  • the width of the section 50 is less than that of the terminal 18, for example by half, so as to free a passage space for a tightening screw 54.
  • the end 48 is widened to come opposite the pad 44, and the screw 54 passes through aligned orifices made in the end 48 and the pad 44 before being screwed into a nut 56 carried by the base 16.
  • the section 50 is made in tinsel to present a certain flexibility, and between the head of the screw 54 and the end 48 is inserted a support lug 58 integral with the cylinder head 52.
  • the cylinder head 52 is rigidly fixed, for example by a screw, not shown, to the housing of the trip unit 14 , while the nut 56 is resiliently mounted by a spring 60 on the base 16.
  • the pallet 62 of the electromagnetic trip device is placed opposite the cylinder head 52, while the base of the bimetallic strip 38 is fixed by a screw 64 to the end 48 and lug 58 assembly.
  • the screw 54 extends perpendicular to the pad 44 by being inclined and opening onto the narrow lateral face of the trip unit 14 on the side of the terminals 18, in an area covered by the terminal cover 22.
  • the trip unit 14 includes for each conductor 36 a disconnectable connection 42, that is to say three connections in the envisaged case of the three-pole circuit breaker.
  • the floating mounting of the pads 44 allows effective tightening and good electrical contact on the ends 48 and the legs 58, when the bolts 54, 56 are screwed, despite the inevitable relative positioning defects of the three legs 58. It is clear that after tightening the bolts 54,56, the trigger block 14, the legs 58, the pads 44 and the nuts 56 constitute a rigid assembly fixed to the base 16 by the springs 60 which compensate for the positioning faults of the legs 58.
  • the trip unit 14 is rigidly fixed to the circuit breaker unit 12 by simply tightening the bolts 54, 56 which at the same time provide the electrical connection.
  • the bimetallic strip 38 is heated in contact with the conductor 36, but it should be noted that the invention applies to bimetallic circuit breakers traversed by the current or to bimetallic strips indirectly heated by a carried winding by the yoke 52.
  • the magnetic trip device 40 can also be of a different type and the arrangement of the connection pad, in particular the value of the inclination, can be different without departing from the scope of the present invention.
  • connection pad is used in the description above in its general meaning of contact zone, this pad not necessarily being a rigid flat surface and naturally applying to the contact face of the foils forming the conductor 50.
  • the assembly and disassembly of the trip unit does not require any particular skill or knowledge and can be carried out by the user or the distributor, allowing a reduction in device stocks. Any false maneuver is excluded, the correct tightening of the three screws translates a correct fixing and a good electrical connection. After fitting and possibly sealing the terminal cover, the connection screws are inaccessible. One can consider other means of tightening than screws, the main thing being access to these tightening means from the side face of the circuit breaker housing to reduce the length of the housing.
  • the fixing screw is not necessarily offset laterally, passage through a central orifice of the conductor being possible by isolating the conductor screw by any suitable means, for example by interposing an insulator or using a screw made of material insulating.
