Definitions

  • auxiliary blocks used in the prior art have projecting levers and visible, and it's easy to visually check their positions relative to those of the circuit breaker.
  • the problem is different for auxiliary blocks having no accessible joysticks.
  • the actuating element of the mechanism is integrated in the box and must be able to be coupled to the circuit breaker or other auxiliary blocks. The association is carried out blind with mounting risks incorrect in the event of a mismatch in the state of the mechanisms.
  • Document DE-U-9302254 relates to the association of a circuit breaker with a signaling module intended to indicate an overcurrent fault or a fault of short circuit when the circuit breaker trips.
  • the modular coupling of two housings is carried out by means of mechanical connections, one of which is connected to the trigger lock, and the other of which is connected to the switching.
  • An overcurrent fault is signaled electrically by an indicator luminous, while a short circuit fault is additionally indicated by an indicator mechanical consisting of a button projecting from the front face.
  • the sinking of the signaling button resets the device.
  • the high or low position of the mechanical indicator allows to visually check the state of the mechanism of the module compared to that of the circuit breaker.
  • the object of the invention is to provide an auxiliary signaling or trigger allowing a reliable association in state agreement with a circuit breaker or other auxiliary unit.
  • the auxiliary unit according to the invention is characterized in that the element actuator is provided with an access key, and that said second orifice comprises a groove arranged in a lock allowing the passage of the key in the single open position of the actuating element, the fitting of the tab drive in the first or second female coupling member intervening when the mechanism of the adjacent circuit breaker or auxiliary block is itself in the same open state.
  • the lock is formed by a groove made at the end of the second curvilinear opening.
  • the key has a stop intended to come into engagement against the adjacent box to prohibit the joining blocks when the corresponding mechanism is not the open state.
  • the first lateral face of the housing comprises at least two clipping members formed by elastic hooking lugs intended to snap into the cells of the adjacent housing.
  • the keying means include a first male blocker associated with a first male orienter on the first lateral face. and one first female centering device associated with a first female orienting device on the second face side, the assembly being arranged to allow the association of at least two blocks signaling aids.
  • the polarizing means comprise a second male centering device associated with a second male orienter on the first lateral face, and a second centering device female associated with a second female orienter, the assembly being arranged for allow the addition of an auxiliary signaling unit on the second side lateral, and to prohibit the association of the opposite side on the first lateral face of the auxiliary trigger block.
  • an auxiliary block 10 for signaling or tripping is attached to the transverse face 12 of a circuit breaker 14 with coupling of a link mechanical trigger, and a drive linkage of the joysticks.
  • the block auxiliary 10 is housed in a casing 16 of molded plastic having a profile identical to that of the case 18 of the circuit breaker 14.
  • Auxiliary unit 10 has no visible handle and is made up of two change-over circuits, each comprising a movable contact cooperating with two fixed contacts connected to a pair of connection terminals.
  • the mobile contact is actuated by means of a control mechanism, of which only the actuating element in manual operation 20 is shown in FIGS. 3 to 5.
  • the actuating element 20 of the auxiliary unit 10 is formed by a base 22 rotary integrated inside the housing 16, and having a limited angular movement corresponding to the stroke of the handle 24 of the circuit breaker 14 between the position opening and closing position.
  • Base 22 is fitted with a tab drive 26 projecting from the housing 16, and disposed opposite an orifice 28 curvilinear formed in the transverse face 12 of the circuit breaker 14.
  • the end of the drive tab 26 is shaped according to a key 30, and the right part of the orifice 28 has a groove 32 of form conjugated with the key 30 so as to constitute a lock ( Figure 2).
  • the support 34 pivoting of the handle 24 of the circuit breaker 14 comprises a first female coupling member 36 moving along the orifice 28 inside the housing 18.
  • the male drive tab 26 of the element actuator 20 engages in the first female coupling 36 to form the drive link between the auxiliary unit 10 and the circuit breaker 14.
  • the location of the groove 32 corresponds to the opening position of the circuit breaker 14, and the key 30 can only fully penetrate the orifice 28 at the level of the bloodletting 32.
  • a first coupling condition consists in placing the actuating element 20 in the open position of the auxiliary unit 10, so as to position the key 30 opposite the groove 32. If the auxiliary unit 10 is in another position, for example in the closed position, any attempt to associate with the circuit breaker 14, is made impossible following the arrival in engagement of the end 33 of the key 30 of the housing 14.
  • the second mating condition is to place the first organ 36 female coupling in alignment with the groove 32 of the port 28, which is only possible in the open position of the circuit breaker 14.
  • the drive tab 26 can then enter the first coupling member 36 in the direction of the arrow F1 ( Figure 4) to form the drive link when the circuit breaker 12 and the auxiliary unit 10 are joined by their respective faces.
  • the key 30 can penetrate in the groove 32 of the lock, but abuts against the edge 38 of the support 34 of the lever 24 by preventing any nesting in the first member coupling 36 ( Figure 5). This results in a lateral spacing between the two boxes 18, 16 of circuit breakers 14 and auxiliary unit 10, signaling to the installer the handling error, and the mismatch of the states between the two modules.
  • each auxiliary unit 10 for signaling or triggering is carried out using coupling means similar to those used for circuit breaker 14, and with additional polarizing means preventing certain combinations.
  • the base 22 of the actuating element 20 of each auxiliary unit 10 Opposite the drive tab 26, the base 22 of the actuating element 20 of each auxiliary unit 10, comprises a second female coupling member 40 (FIGS. 3 to 5), having a similar shape to that of the first coupling member 36 of the circuit breaker 14.
  • the second member coupling 40 moves along a curvilinear orifice 42 formed in the face lateral 44 on the left of the housing 10 ( Figure 1).
  • Office 42 is equipped with a groove 32 of identical shape to that of the orifice 28 of the face 12 of the circuit breaker 14, and arranged in alignment with it in the joining direction of the modules.
  • the same coupling conditions are applicable for the formation of the drive link between the mechanisms respective of the two blocks.
  • the two mechanisms must be simultaneously in the state open so as to allow the key 30 of one of the modules to be inserted into the groove 32 of the adjacent lock, and in the second coupling member 40 of the other module.
  • Figures 6 to 9 show the association of two 10 A auxiliary blocks of OF (open / closed) or SD (fault signal) signaling, each box 16 having a width of 9 mm.
  • each auxiliary unit 10A There is a protrusion on the right side face 46 of each auxiliary unit 10A, the drive tab 26, a trigger stud 48, a pair of clipping 50, 52, a first male centering device 54, and a first male orienting device 56.
  • the drive tab 26 passes through an orifice 58 of similar shape and aligned with that 42 on the other side 44, but lacking a lock.
  • the trigger nipple 48 engages in the trigger lever of the adjacent module to constitute the mechanical trigger link.
  • the clips 50, 52 are formed by elastic hooking lugs intended to snap into cells of the adjacent housing.
  • the first male centering device 54 comprises a tubular rod arranged at the upper part of the housing 16, while the first male orienter 56 is provided a semi-cylindrical stud provided in the lower part of the housing 16 in the vicinity at near the fixing rail.
  • the opposite side face 44 of the left side of each auxiliary unit 10A is provided with more than the orifice 42, a first female centering device 60, and a first orienter female 62.
  • the first female centralizer 60 allows the fitting of the tubular rod of the first male centering device 54 to obtain a multidirectional blocking in the plane of junction of the two boxes.
  • the first female orienter 62 has a notch in U at the lower part of the face 44 allowing a slight play of the male orienter 56 in the direction of the notch.
  • Figures 10 to 13 show the association of an auxiliary block 10 A of signaling with an auxiliary trigger block 10B, the latter having a width of 18 mm.
  • the auxiliary signal block 10A must be placed at left of the auxiliary trigger block 10B, which can be made up by an undervoltage release MN, or an emission release MX current, intended to transmit a trip order to circuit breaker 14.
  • the block signaling auxiliary 10A is identical to that described with reference to FIGS. 6 to 9, and comprises the first male and female centralizers 54, 60, and the first male and female counselors 56, 62.
  • the right side face 66 of the auxiliary trigger block 10B includes clips 50, 52, a trigger pin 48, a drive tab 26 passing through an orifice 58, a second male centering device 68, and a second orienter male 70.
  • the second male centering device 68 and the second male orienting device 70 are formed by cylindrical studs projecting from the lateral face 66.
  • the left side face 72 of the auxiliary unit 10B is provided in addition with the orifice 42, a second female centering device 74, and a second female orienting device 76.
  • the second female centering device 74 is placed in the same place as the first centering device female 60, and can receive the first male centering device 54, if the auxiliary unit 10A of signaling is juxtaposed to the left of the auxiliary trigger block 10B (case of Figure 12).
  • Figures 14 to 16 show the association of an auxiliary signal block 10A with circuit breaker 14.
  • Auxiliary signal block 10A is identical to that described above, and comprises the first male and female centralizers 54, 60 and the first male and female orienters 56, 62.
  • the lateral face 12 of the circuit breaker 14 is equipped with a third female centering device 78, and a third female centering device 80.
  • the third female centering device 78 can receive the first male centering device 54, but also the second male centering device 68. It is the same for the third female centering device 80 in which the first male guide 56, or the second guide can engage male 70. It is therefore possible to associate the combination of FIG. 10 with the face 12 of the breaker.
  • auxiliary signaling blocks 10A can never be inserted between an auxiliary trip block 10B, and the circuit breaker 14.
