Definitions

  • the invention relates to a variable switch box for installation in power tools or similar devices in order to incorporate as a control element the conventional motor switch or the motor protection switch provided with protection against overload and to be able to assign an arrangement for undervoltage release to one of these switching elements as required or to retrofit or retrofit the existing switch box.
  • the object of the invention is to develop a control box as an operating element for installation in existing power tools or devices, which, according to the arrangement and functionally, enables a conventional motor switch or a motor protection switch to be easily supplemented with a device for undervoltage release and to be able to combine.
  • the (different) equipment of the switch box should be realizable from the outset, retrospectively or alternatively in the manner of a modular system and essentially using existing or easily retrofittable devices.
  • the invention forms a switch box for power tools or the like.
  • the execution of a multi-pole motor protection switch known from DE-PS 19 09 555 with thermal overcurrent tripping, without its switching latching and locking device can be assigned to the undervoltage monitoring device, which is fed via a rectifier bridge circuit from the AC supply network, and this Compilation by means of a functional coupling by means of the latching mechanism contained in the switch box can be switched on and off manually by means of two actuation buttons and triggered and secured electrically.
  • the compilation can also be done with a simple motor switch instead of the motor protection switch; viewed in itself, it is even operational without the installation of the arrangement for undervoltage release.
  • the switch box according to the invention can be varied and / or supplemented, as it were, in a modular manner, in exchange for the previous control element of an electrical device, as required or expedient.
  • claim 2 relates to the specific design of the lever member as a central element of the actuating and latching mechanism, claim 3 to the spatial-constructive design of the entire switch box, claim 4 to useful measures for dust and splash water protection of the construction, and Claim 5 to the assembly precautions on the switch box for safe Bracket within the relevant electrical device.
  • the power supply of the device-side electric motor is switched to two poles by actuating the motor protection switch 1 and the device is at the same time thermally secured against overload.
  • the two switching paths are bridged at their terminals against one another by the interference suppression capacitor 2 and on the other hand by the rectifier arrangement 3 in a single-phase bridge circuit for energizing or supplying the electromagnetic release element 4 for the mains voltage control.
  • the motor protection switch 1 and the trigger element 4 interact in mutual coupling via an actuating and latching mechanism 5, which is simply indicated in the circuit diagram by a dashed active connection line.
  • the switch box consists of a one-sided open insulating material housing 6 in the form of a parallelepiped, on the operator side of which, within a trough-shaped front panel, the broad actuation handles as the switch button 7 and the switch button 8 are adjustably inserted and are guided in housing sockets, and which is on the side below in front of a strain relief device 9 is provided with insertion openings for the connection cable as for the motor cable.
  • the actuating and latching mechanism 5 cooperating with the above-mentioned functional elements 1 and 4 essentially consists of the elongated L-shaped lever member 11. The same is in the area of its two corner points at the ends of the pressure pins guided in the housing 6 with sufficient play the on and off buttons 7 and 8 are pivoted without affecting their mutual adjustability consoling.
  • the lever member 11 is given a torque in this phase with effect on its opposite end of the bearing, through which the Ausachaltknopf 8 pulled against the further housing stop 13 'formed by the end edge of its guide bush and at the same time the hinged armature 10 of the release member 4 via the coupling piece 16 is held in the waste disposal.
  • the lever member 11 has, in addition to the switching cam 12 arranged laterally offset to the rotary bearing point for the switch-on button 7 in the other direction, offset a latching cam 14 which is rigidly angled upwards by 90 ° and provided with a grinding or evasive profile along the side, which is in the train the switch-on actuation under certain conditions is able to hold positively on the edge of a housing projection 15 in order to hold the motor protection switch 1 in the switch-on position after manual release of the switch button 7.
  • the unlatching spring 17 presses the lever member 11 loaded by it into the switch-off position defined by the housing stop 13 'and at the same time pushes the hinged armature 10 against its own weight into the release position, this possibly being opposite the yoke leg of the electromagnet (4) on a special one Can stop the housing (13 ").
  • the latching cam 14 can then, and only then, hold positively on the edge of the housing projection 15 if the mechanically relieved of the coupling piece 16 of the lever member 11 and, as a result, preparing for the magnetic yoke by reducing the air gap Electromagnet 4 tilted hinged armature 10 is tightened and held by its network-side excitation. This creates a counterforce by which the switch-off torque of the unlatching spring 17 is canceled, whereby the torque imparted to the lever member 11 on the part of the return spring of the motor protection switch 1 comes into effect and allows the positive engagement between the latching cam 14 and its housing projection 15 to take place in the manner described above.
  • the hinged armature 10 is unable or no longer able to hold onto the magnetic yoke of the electromagnet 4, whereupon the unlatching spring 17 again acts arrives, the latch releases and the lever member 11 of the mechanism can return to the switch-off position in the above-described effect on the functional elements controlled by it.
  • the manual actuation of the switch-off button 8 causes the lever member 11 to be supported by the forces of the tensioned release spring 17 and. the return spring of the motor protection switch 1 and, in opposition to the holding force of the electromagnet 4, provides a resultant torque which removes its positive locking and allows the overall arrangement to return to the off position in this way.
  • the excitation of the release element 4 causes its hinged armature 10 to hold onto the magnetic yoke and thereby compensate for the influence of the unlatching spring 17, so that when the switch 7 that was previously fully pressed in by hand is released under pressure of the operated motor protection switch 1 on the Mechanics (5) the entire arrangement is latched in the on position.
  • the switch button 8, which is mechanically coupled to the switch button 7, has noticeably emerged from the front of the housing 6 of the switch box and is therefore available if required Ready to turn off.
  • the insulating material housing 6, which is open on one side, can be closed dust-tight after the assembly, wiring and storage of the interference-suppression capacitor 2, which is only indicated by dash-dotted lines, by means of a cover, which is also not particularly shown in the drawing, for which purpose several flaps are angled away from its groove are to lock elastically with corresponding approaches of the side walls of the housing 6.
  • the two actuating buttons 7 and 8 are arranged to be largely splash-proof within recesses of the front panel by nesting overlap of the guide bushings for their pressure pins on the part of the button edge drawn in downwards.
  • the switch box has its holder below one Rectangular mounting opening of the electrical device in question finally on two opposite outer sides of the housing 6 via a locking spring tongue 18 molded thereon, which in cooperation with a sufficiently overlapping opening flange on the front plate in a simple manner and without the aid of further fastening elements, a secure mounting and enable easy disassembly of the switch box.
