Definitions

  • the invention relates to a contactor, in particular auxiliary or motor contactor, with a module for limiting or damping voltage peaks, the coil connecting screws and their connecting rails being arranged in the contactor housing near a side wall of the housing.
  • RC modules are used to dampen voltage peaks that occur when AC contactors are switched off and can reach a multiple of the nominal actuation voltage, where R stands for resistance and C for capacitor.
  • Damping modules namely diode modules or varistor modules, are used to limit voltage peaks that occur when DC-operated contactors are switched off and that can also reach a multiple of the nominal operating voltage.
  • the electrical parts of the modules are usually potted with plastic or housed in a separate housing, so that a small structural unit is created.
  • connection lines are led out of each module, via which the corresponding module can be connected in parallel to the coil of the contactor.
  • the outer ends of the connection lines are clamped to the normal coil connection terminals by means of coil connection screws, the ends of the connection lines as well as all other connection lines of the contactor having to be inserted into the terminals from the outside. In practice, this leads to considerable difficulties, since the coil connection terminals are already occupied with the normal connection lines.
  • the invention has for its object to provide a contactor in which the module can be connected very easily, without any connection problems or space problems when converting or retrofitting the contactor.
  • the module has electrical connections which are connected to the connecting rails in such a way that the coil connection screws are occupied exclusively by the usual connections, that a recess is provided in the side wall of the housing, in which the module is inserted and that the module is surrounded by a plastic housing which is adapted to the recess and is in alignment with the outer surface of the side wall.
  • connection problems there are no more connection problems if the normal coil connection terminals are already occupied, for example, with two other connection lines. There is no need to work on the wiring of the module. The failures caused by the previous connection problems can no longer occur. There is also a particularly simple construction. Above all, with this design, the contactor can be converted or retrofitted without loosening the connecting cables and without loosening and reattaching the module.
  • a contactor 1 which has two housing parts 2 and 3 in a manner known per se, the housing part having 3 feet 4 and 5 or other fastening devices for fastening to a mounting plate, a mounting rail or the like.
  • the housing part 3 is the magnet system of the contactor in a known manner, while in the Housing part 2 the contact system is housed.
  • the contactor is closed by a cover 6, through which a connecting element 7 can protrude, which can be used for connection to actuating elements or to which structures, such as additional contact units, can be connected.
  • two rows of bores 8 and 9 lying opposite one another are provided, through which the contact terminal screws underneath can be actuated by means of a screwdriver.
  • the outside bores 10 and 11 serve to actuate the coil connection screws 12 and 13 underneath according to FIG. 4.
  • the coil connection screws 12 and 13 and their connecting rails 16 and 17 are arranged in the contactor housing 2 near a side wall 24 of the housing, as shown in FIG. 1.
  • the coil connection screws 12, 13 sit on terminals 14 and 15, which are essentially designed as rectangular frames and open downwards or upwards in FIG. 4 and are used for inserting the normal connecting lines and for clamping.
  • the connecting rails 16, 17 are fixedly connected to the terminals 14, 15 and thereby arranged in a fixed manner in the housing, on the other hand, the ends 18, 19 of the connecting rails 16, 17 are in electrical connection with spring clips 20 and 21, which are connected via connecting lines 22 and 23 lead to the not shown coil of the contactor.
  • a recess 25 is provided in the side wall 24 of the housing part 2, in which the module 39 is inserted with its housing 28, figuratively seen by parallel displacement from the position according to FIG. 3 in the direction of FIG. 1. 4, the module 39 has electrical connections which are assigned in the sequence with the reference numerals 31, 33, 35, 37 or 32, 34, 36 and 38 and which are in direct connection with the connecting rails 16 and 17.
  • the module 39 is surrounded by a plastic housing 28, the shape and configuration shown being to be regarded as an exemplary embodiment.
  • the plastic housing 28 is adapted in shape to the recess 25 in the side wall 24. In the operating position, the outer surface of the housing 28 is aligned with the outer surface of the side wall 24, that is to say lies in the same plane as this.
  • the plastic housing 28 is essentially rectangular and has, in the area of the leaf springs 31 to 34 explained below, rectangular savings 29 and 30, in which correspondingly shaped rectangular projections 26 and 27 of the side wall 24 of the housing part 2 engage.
  • the parts 31, 33 and 32, 34 of the electrical connections which protrude from the plastic housing 28 of the module are designed as leaf springs which are pressed onto connection rails 16, 17, as shown in FIG. In this way, a vibration-free mounting of the plastic housing 28 and thus of the module 39 in the recess 25 is ensured above all.
  • the leaf springs can be bent in the form of an acute-angled triangle with the leaf spring parts 31, 33 or 32, 34. In this way, there is an even greater spring travel and thus a particularly high level of contact reliability.
  • edges of the plastic housing 28 and / or the edges of the recess 25 are provided with latching points, so that the plastic housing engages when pressed into the recess 25 and is held in the operating position.
  • latching points small projections or ribs or grooves can be provided as locking points, especially since the material of the plastic housing can have a certain resilient elasticity.
  • a notch 40 is provided in the side wall or in the lid 6 of the housing 2 near an edge of the plastic housing 28 for the use of a screwdriver to loosen the plastic housing.
  • this notch 40 is located on the inner edge of the cover 6.
  • the module may be easier to replace or the contactor may be equipped with one or the other desired module. If the contactor is to work without a module, an empty housing corresponding to the housing 28 can be inserted into the recess 25.
  • the recess 25 and the module 28 or 39 are designed in such a way that there is security against rotation. This is particularly important for DC-operated contactors, because here the module connection + and ./. must be strictly observed.
  • a further advantageous embodiment is proposed, which consists in that the outer surface of the plastic housing 28 is provided with color or lettering for identifying an RC module 42 or a diode module 45 or a varistor module 47.
  • FIG. 5 shows a simplified circuit diagram for a coil 41 of an AC-operated contactor with the normal connections or coil connection terminals 14 and 15 according to FIG. 4, which is why the same reference numerals have been used here. This also applies to the module connection lines 37 and 38.
  • the RC module essentially contains a resistor 43 and a capacitor 44.
  • FIG. 6 illustrates a simplified circuit diagram for a coil of a DC-operated contactor with a diode module connected in parallel 45 with a diode 46 or optionally a varistor module 47.
