Definitions

  • the invention relates to a contactor with a housing, in which a contact system is provided near the mounting side and an actuating device is provided vertically above it, thermal triggers and magnetic triggers which are operatively connected to the actuating device being arranged at each phase on one side of the actuating device are.
  • a motor protection device normally consists of a contactor to which a thermal motor protection is assigned. Both the entire contact system and the magnet system by which the contact system is actuated are accommodated in a single housing of a specific design, specifically the magnet system is either on the mounting side of the contact system or on the side of the contact system remote from the mounting side, ie above this, arranged.
  • the movable armature of the magnet system is connected to the contact bridge holder of the contact system via a coupling.
  • the contactor specified at the beginning has a relatively compact design due to its design, so it only requires a small amount of space on a mounting wall or in the control cabinet and in which the wiring can also be carried out largely within the contactor.
  • short-circuit fast releases or magnetic releases are also provided, which act on the switch lock and thus on the contact system and, in the given case, switch off the motor protection switch.
  • An undervoltage or shunt release can also be provided.
  • this contactor serving as a motor protection switch is that it can only be switched on manually by means of the ON key and a deliberate deactivation can only be carried out manually by means of an OFF key, apart from the automatic deactivation by the described motor protection.
  • the invention is therefore based on the object to design a contactor so that it also offers the possibility, in addition to the manual control, to be switched on or off from any desired or suitable location without increasing the space requirement of the contactor and the construction costs noticeably more expensive.
  • an electromagnetic drive is arranged on the other side of the actuating device, the armature of which is connected to an extension piece of the common contact bridge holder of the contact system via articulated toggle levers, and that a slide is provided is on which on the one hand the toggle levers and on the other hand the thermal and magnetic triggers attack.
  • the main advantage here is that the mass to be moved when the contactor is triggered is relatively small, so that the triggering takes place very quickly. It also follows due to the toggle lever construction in the case of quick release, compared to the prior art, a substantial increase in the distance of the movable contact bridges arranged in a common contact bridge holder. This significantly improves the short-circuit protection of the contactor.
  • the contactor according to the embodiment shown in the drawing has a housing with a lower housing part 1 and with a lid-like upper housing part 2, which is shown in dash-dotted lines in FIGS. 3 and 4.
  • the lower housing part 1 houses a contact system, not shown, with fixed contact rails and contact connection screws 3, 4, for the connection of three phases.
  • the contact system, not shown also contains a common contact bridge holder with three spring-loaded contact bridges.
  • actuating device in the present exemplary embodiment a key switch 5 with a power button 6, a power button 7 and a setting wheel 8 for the current setting provided.
  • the switching lock 5 contains a mechanical system which is designed such that the contact bridge holder with the contact bridges can be brought into the switched-on position when the switch is pressed with respect to the fixed contact rails.
  • the switch-off button When the switch-off button is pressed, the switch-off process takes place accordingly.
  • thermal triggers 9 cooperate with the switching mechanism, and in each phase such a thermal trigger with bimetal rail 10 is arranged on one side of the switching mechanism, in the illustrations of FIGS. 1, 2 and 3 on the left side. Behind the plate 1 (FIG. 3), magnetic triggers or short-circuit fast triggers, not shown, are arranged for each phase, which are also operatively connected to the switching mechanism.
  • the space on the other side of the key switch 5, namely on the right side of the illustration according to FIGS. 1, 2 and 3 and below the housing cover 2, is used to accommodate an electromagnetic drive 13, the armature 19 of which acts on the switch 6.
  • the ON button 6 is provided with a plastic pin 12 protruding from the switching lock 5, on which a projection 25 of the armature 19 rests.
  • the pin 12 can be rectangular in cross section according to FIG. 1, it being advantageous that the projection 25 then is triangular in cross section, so that one horizontal triangle leg rests from the pin 12 and the other triangle leg partially extends around the front surface of the pin 12 according to FIG.
  • the core 14 and the armature 19 of the electromagnetic drive are designed with three legs.
  • the coil 15 is fastened on the center leg of the core 14.
  • the coil has a plastic base 16 on which the two coil connections 17 and 18 are firmly mounted with their connecting screws.
  • the armature 19 is advantageously pivotally mounted in this embodiment.
  • the anchor 19 in the illustrated embodiment of the armature 19 in the region of its web 26 is surrounded by a U-shaped yoke 24 made of plastic and is connected to it by a cross section, for example.
  • the yoke 24 is held in the region of one end of the web 26, according to FIG. 4, near the right end of the web by means of a pivot axis 23 and two lateral bearings 21 and 22 (FIG.
  • the coil 15 and the core 14 of the electromagnetic drive can be positively in the space below the housing cover 2, z. B. between guide ribs, stops or the like.
  • the freedom of movement of the pivotable armature 19 can also be limited by stops in a manner known per se.
  • An advantageous constructive solution for holding the electromagnetic drive is that the coil 15 and the core 14 are detachably held in the housing parts 1 and 2 by means of molded plastic pins 31, 32 and 33. This simplifies assembly.
  • FIGS. 1 to 4 illustrate another, particularly advantageous embodiment of a contactor according to the invention.
  • the armature 19 of the electromagnetic drive 13 is in the image on the underside, that is to say on the side facing the contact system 34.
  • the armature 19 is held on a yoke 24, which is arranged at one end, in the image at the left end, on a pivot bearing 41.
  • the other end of the yoke 24 is connected via a joint 42 with a toggle lever to the toggle lever parts 36 and 37, the Toggle lever parts 36 and 37 are connected to one another by means of a joint 53.
  • toggle levers are arranged next to one another perpendicular to the plane of the drawing in FIGS. 5 to 8, with such a distance from one another that, as shown in FIG. 7, they can swing out on both sides of the coil 15 of the electromagnetic drive 13.
  • the toggle levers are attached to an extension piece 38 of a common contact bridge holder 39 by means of a joint 54.
  • the contact bridge holder 39 carries all spring-mounted contact bridges in a known manner.
  • the toggle levers are expediently accommodated in cutouts in the extension piece 38.
  • a compression spring 56 is inserted, which is supported with its upper end on the inside of the housing cover 2.
  • a slide 40 is provided parallel to the latter, which can be displaced parallel to the extension piece in lateral guides (not shown).
  • the slide 40 has a slot-like recess 43, in which a nose projection 46 of the toggle lever part 37 engages in the rest position of the contactor according to FIG. As illustrated in FIG. 5, the nose projection 46 has an inclined surface on the top.
  • Another recess 44 of the slider 40 serves to receive a nose projection 47 of a magnetic trigger 35. Since perpendicular to the image plane, for example, FIG. 5 has three magnetic triggers 35 for the three phases are arranged side by side, the slide 40 accordingly also has three recesses 44.
  • the nose projection 47 is formed on a head part 57 which is connected to the magnet armature 58 of the magnetic trigger 35.
  • a compression spring 59 is inserted between the head part 57 and the coil body of the magnetic release 35.
  • the nose projection 48 has an inclined surface on the underside according to FIG. 5 and is attached to a plate 60 which is held in a horizontally displaceable manner. Three such plates 60 or strips are provided, each of which engages the upper end of the thermal release 9 in question.
  • a switch-off button 7 is provided, which is arranged in this embodiment such that it acts on the upper end of the slide 40 when actuated.
  • a reset button 49 is also provided. The arrangement and design is such that, when actuated, the toggle levers 36 and 37 can be returned to the normal rest position from the release position or the bending position according to FIG. 7.
  • the contactor is in the rest position, hd it is not switched on.
  • the contactor can be switched on from a remote operating point, for which purpose the coil connections 61 are used, which are arranged in FIG. 5 in the upper part of the contactor, but which can also be moved downward into the plane of the normal connections 3, 4.
  • the contactor picks up, ie the armature 19 moves upwards, whereby the yoke 24 and the toggle levers 36, 37 and the extension piece 38 are carried along with the contact bridge holder 39, so that the contacts of the contact system 34 close .
  • the slide 40 remains in its original position.
  • the switched-on state is shown in FIG. 6. Both switching on and switching off the contactor are normally done by the electromagnetic drive.
  • the switch-off can also be carried out by pressing the switch-off button 7, so that the slide 40 is moved downwards.
  • the upper edge of the slot-shaped recess 43 meets the upper inclined surface of the nose projection 46 of the toggle levers, so that they are pivoted to the right beyond the extended dead position to the left from the slight kink position shown in FIG. 5, so that they move to the left into the position according to Figure 4 swing out.
  • the compression spring 56 rapidly swings out and displaces the extension piece 38 and the contact bridge holder 39. A short circuit is simulated by these processes. So even if the coil 15 in the off position acc. FIG.
  • the contactor can only be switched on again by pressing the reset button 49, as a result of which the toggle levers are returned to the right in the original position according to FIG. 5 with a slight bend over the dead center position.
  • the toggle levers are then held to the right in this slight kink position. If a short circuit occurs in a phase, the relevant magnetic trigger 35 attracts, so that the slide 40 is displaced downward again over the nose projection 47, so that then again when the slide 40 strikes the top edge of the recess 43 on the nose projection 46 Toggle lever are pivoted into the left kink position, so that an abrupt switch-off takes place again.
  • the thermal triggers 9 which swing out in the event of an overload with the upper end to the left, so that the inclined surface of the nose projection causes the slide 40 to be moved downward and the same switching-off process as described takes place again.
  • the main advantages of the contactor described above are the fact that magnetic adjustment is possible both by hand and by remote control. Another advantage is the versatile functionality, the great short-circuit protection by increasing the distance for quick release. It is also advantageous that the contactor can quickly see which cause led to the failure. To this end, signal contacts or lamps or the like can also be provided, that indicate the failure.
  • the contactor can also be equipped in a manner known per se with auxiliary contacts, which are placed, for example, in a lug on the end face of the housing cover.
  • auxiliary contacts which are placed, for example, in a lug on the end face of the housing cover.
  • a mechanical connection with the extension piece 38 or the contact bridge holder 39 is to be provided here.
  • FIG. 9 shows an auxiliary contact 51 or an additional contact for the coil 15 of the electromagnetic drive in a purely schematic manner.
  • the auxiliary contact 51 can be attached with the one contact piece to a spring leaf spring 52 which works in such a way that when pressed on, for example by a displaceable actuating element 50, the spring leaf spring 52 jumps upwards into the dashed position.
