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 The purpose is to clamp the outer ends of the connection lines 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.
  • With DC-operated contactors difficulties can arise when the connecting lines are mixed up, with regard to the positive and negative connections. Apart from the unattractive appearance of the connection lines, which start loosely around the cover of the contactor and extend from the module to the coil connection terminals, the space requirement of the modules is disadvantageous in this arrangement.
  • the contactors are additionally equipped with contact units that are attached to the cover of the contactor. You then have to loosen the module with the connecting cables each time and then later fix it again on the front of the converted contactor and also clamp the connecting cables again. All of this is cumbersome, leads to uncertainties and failures.
  • 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 connection rails in such a way that the coil connection screws are occupied exclusively by the usual connections.
  • 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.
  • a particularly advantageous embodiment of the invention is achieved in that a recess is provided in the side wall of the housing, in which the module is inserted.
  • the advantages explained above are achieved in a structurally particularly simple manner.
  • the contactor can be converted or retrofitted without loosening the connecting lines and without loosening and reattaching the module.
  • the cover 6 two mutually opposite rows of holes 8 and 9 are provided, through which one can operate the underlying contact terminal screws 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 firmly connected to the terminals 14, 15 and thus arranged in a fixed manner in the housing, and 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 lead via connecting lines 22 and 23 to the coil of the contactor, not shown.
  • 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 are to be considered as an 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 out of the plastic housing 28 of the module projecting parts 31, 33 and 32, 34 of the electrical connections are designed as leaf springs which are pressed onto connection rails 16, 17, as shown in FIG. 4. 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. In this way, the module may be easier to replace or the contactor to be replaced equip 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 parallel connection of a diode module 45 with a diode 46 or optionally a varistor module 47.
