Definitions

  • the invention relates to a single or multi-pole device circuit breaker in small format and narrow construction.
  • Such controls are used in a variety of electrical devices and equipment, such as Household appliances, office machines, control devices for production and assembly machines or the like, built in, in order to take over, as such, beyond their actual switch function, at the same time protecting the relevant circuits and consumers against short-circuiting and overloading, for which up to now mostly a separate or fuse is provided, which has to be replaced after each defect in a complex and cumbersome manner.
  • this device circuit breaker is comparable to the known miniature circuit breaker, which has a mechanical spring mechanism for actuating a switch contact arrangement that can be switched on manually and can be triggered manually, electromagnetically and electrothermally in front of an arc extinguishing device.
  • this miniature circuit breaker is usually switched on at all times and should only enable it to be switched on again in the event of a short-circuit or overcurrent trip after the fault has been eliminated.
  • the function of the circuit breaker is a switch element that is frequently operated by hand. which the above-mentioned monitoring functions are additionally entered in order to be able to dispense with the separate need for protection within the switched consumer circuit.
  • efforts are made to add a further contact arrangement to the device switch or circuit breaker, which, according to its on or off position within a separate signal or control circuit, is intended to suitably switch the respective switch position and thus the operating state of the electrical device to be switched , for example optically or acoustically, or to control other auxiliary devices according to the switch position or the switching state.
  • the object of the present invention is to develop a device circuit breaker whose protective devices against short-circuit and overload can be accommodated in connection with a changeover contact arrangement for signal or control purposes by suitable design and arrangement of all components within the specified dimension range of the normal built-in switch design.
  • a device circuit breaker according to the preamble of claim 1 according to the invention in that the entire switching mechanism from the combination of a clamping body with several functional approaches, a V-shaped flat release lever, the movable pivoting contact piece and a one-armed driver lever for the signal switch composed, which are arranged at a central point for themselves pivotable about a common axis of rotation, functionally interlocking and partially supported against each other and overall against the housing by means of individual spring elements.
  • the switching mechanism is composed of a total of four individual lever members mounted on the switch housing so as to be pivotable about the same axis of rotation, including three further spring elements.
  • the basic element is formed by the clamping body made of insulating material with the function protruding from the front at its three corner points approach, which is rotated in the off position by the leg spring wound around a flange and supported against the housing.
  • both the unlatching lever and the movable swivel contact piece are arranged as stamped parts, as is the driver lever, which is again made of plastic, for the signal switch.
  • the V-shaped, flat release lever works via its bow-shaped, extended latch leg with the upper functional approach, against which it is also supported with a counter leg under pressure from the latch spring.
  • the swivel contact piece mounted on it is pressed on its switching arm by the spring, which is supported in front of the right functional approach and creates the contact pressure, in the more extensive guide notch of the left functional approach, which can then suddenly act on the switching arm when the switch is triggered due to this guide play.
  • the electrical supply is via a flexible strand, which is conductively connected to one arm of a T-shaped configuration of the swivel contact in the area of its storage.
  • the on and off actuation of the device circuit breaker takes place with the aid of an outwardly protruding from the housing and through its cover cap toggle, which is pivotally mounted on an axle shoulder of the housing and against the restoring force of the leg spring contained by its shaft.
  • This control knob is coupled to an inward-extending extension in the manner of a knee with the H-shaped connecting member, in the free end of which a push pin is inserted transversely.
  • the pressure pin acts on the upper functional approach of the clamping body during the activation process and adjusts the entire switching mechanism against the restoring force of the leg springs of the control knob and clamping body beyond a dead center.
  • the electromagnetic release member of the switch is a hinged armature system with its magnetic yoke enclosing the magnetic core with the excitation winding in a U-shape on the left Narrow side of the housing is inserted into an appropriate profile and is held therein.
  • the hinged armature of this release element which is mounted on an extension of the outer magnetic yoke leg and tensioned from there by means of a tension spring, in turn has an extension which extends into the functional area of the adjacent switching mechanism in order to trigger a short-circuit release of the switch to the second one adjusted by the tensioned mechanism Impact latch leg of the release lever.
  • the bimetallic strip electrothermal release member of the switch for protection against overload is arranged next to the switching mechanism on the right narrow side of the housing.
  • the bimetallic strip above its insert holder in an appropriate profile of the housing has an adjustment precaution that serves to set the exact release value and is accessible from the outside and continues downwards into one of the outer connecting lugs.
  • the adjustment device welded to this connecting lug is made in one piece with one of the arc guide plates for the quenching device described below.
  • the bimetallic strip with its free actuating end in the switched-on state faces the bow-shaped elongated latch leg of the release lever of the switching mechanism in order to initiate the triggering of the switch from this point after a corresponding deflection due to the load-dependent curvature of the bimetal strip.
  • One of the baffles with its front end forms the fixed contact of the switching path and at the same time the connection point for the end of the field winding of the hinged armature system, while the other baffle - as already mentioned - integrally with the adjustment device for the bimetal strip mechanically and electrically in direct connection with the relevant one Connection flag stands. It is also important that the contact pairing is provided with silver overlay against silver-cadmium oxide, which ensures a high level of arcing, erosion and welding resistance of the contact arrangement with a very low voltage drop, which in addition results in its sudden separation by the triggering Clamping body of the switching mechanism has an advantageous effect.
  • the V-shaped blow loop formed by the contact arrangement itself drives the arc which arises when the switching path is opened extremely quickly from the two contacts and along both guide plates into the quenching chamber.
  • the sheet is then divided, cooled and deionized by means of the sheets, after which the air cushion in front of it, like the gases produced by it, can escape safely into the open.
  • the between the arcing chamber and the connection bracket for the bimetal strips arranged signal changeover switch from two fixed contact pieces inserted into the housing base and reaching outwards with their connecting lugs, between which the switch contact piece, designed as a spring-loaded flip-flop, is mounted on the bend of a further connecting lug engaging in the housing.
  • this flip-flop is provided with an actuation projection which is gripped in a fork-like manner by the driver lever of the switching mechanism in order to synchronize it accordingly, in accordance with the switch-on and switch-off or triggering operation thereof, but electrically independently of the actual switching and monitoring function of the device circuit breaker alternatively, to be switched from one to the other switch position in order to suitably signal the main operating state or existing operating state or to control other processes depending on this.
  • the individual parts thereof can be used and held mechanically, either by themselves and partly mechanically, either individually or as pre-assembled assemblies in the correspondingly designed and prepared insulating housing.
  • this fully assembled housing is designed in its spatial form as an insert, which can finally be provided with an insulating material cap encompassing it on both narrow sides. This cap fully covers the entire assembly space of the switch on one side and acts as a safeguard against loosening of the parts used as well as protection against accidental contact and protection against contamination.
  • the cap is provided on its two narrow sides with molded spring tongues which, in cooperation with the front panel, enable the switch to be detachably held in a corresponding cutout of the electrical device in question or elsewhere.
  • the switching mechanism composed of several lever and spring elements is located approximately in the middle of the flat switch. According to the further construction of the switch, this switching mechanism is located between the electromagnetic release element arranged on the left side of the switch and the electrothermal release element arranged on the right side of the switch. Furthermore, the switching mechanism is below the outward-reaching operating handle, as well as above the contact and extinguishing device of the switch, the contact arrangement of the signal switch and the various external connections.
  • the arc column is then split into partial arcs when it strikes the end faces of the three ferromagnetic quenching plates within the chamber 12, cooled between the plates and deionized. Thereafter, the resulting arc gases as well as the air cushion produced in front of the arc can escape safely and safely through the ventilation slots provided between the metal sheets in the housing wall.
