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 provide protection for the relevant circuits and consumers against short-circuit and overload at the same time, in addition to their actual switch function, for which up to now 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 can be actuated manually using a mechanical spring mechanism and actuated manually, electromagnetically and electrothermally
- Switch contact arrangement in front of an arc extinguishing device 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 should serve to open the respective switch position and thus the operating state of the electrical device to be switched suitable way, for example optically or acoustically, to show or to control other auxiliary devices corresponding to the switch position or the switching state.
- the present invention is therefore based on the object to develop a circuit breaker, the protective devices against short circuit and overload can be accommodated in connection with a changeover contact arrangement for signal or control purposes by a suitable design and arrangement of all components within the specified dimension range of the normal built-in switch design.
- Driver lever for the signal switch composes, which are arranged at a central location for themselves pivotable about a common axis of rotation, functionally interlock and partially supported against each other and overall against the housing by means of individual spring elements.
- the switching mechanism is made up of a total of four individual lever members mounted on the switching housing and pivotable about the same axis of rotation, including three further spring elements.
- the basic element here is the clamping body formed from insulating material with the function protruding from its three corner points on the front approach, which is rotated by the leg spring wound around a flange and supported against the housing in the direction of the switch-off position.
- 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 together with its bow-shaped, extended latch leg with the upper functional shoulder, 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 causes the contact pressure, into the more extensive guide cut of the left functional approach, which then may 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 mounting.
- the on and off actuation of the circuit breaker takes place with the help of an outwardly from the housing and through its cover cap protruding 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 push 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 designed as a hinged armature system, with its magnetic yoke enclosing the magnetic core with the excitation winding on the left in a U-shaped manner Narrow side of the housing is inserted into an appropriate profile and is held therein.
- the folding armature of this release element which is mounted on an extension of the outer magnetic yoke leg and is tensioned from there by means of a tension spring, 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 which is adjusted by the tensioned mechanism To strike the latch leg of the release lever.
- the bimetallic strip-shaped electrothermal release element 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 has a setting above the plug-in holder in a corresponding profile of the housing the exact trigger value serving and therefore accessible from the outside adjustment and continues down into one of the outer connecting lugs.
- the adjustment arrangement welded to this connecting lug is made in one piece with one of the arc guide plates for the quenching device described below.
- the bimetal strip with its free actuating end in the switched-on state faces the bow-shaped, elongated latch leg of the unlatching 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 baffle forms with its front end 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 de relevant connection flag is. 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 the 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.
- 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 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 by hand and partly even mechanically, either individually or as preassembled assemblies, functionally 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 area of the switch on one side and acts as a safeguard against loosening of the parts used as well as a contactor and protection against contamination.
- the cap is provided on the outside on its two narrow sides with molded spring tongues which, in cooperation with the front panel, enable a detachable mounting of the switch in a corresponding section of the electrical appliance in question or elsewhere.
- Figure 1 shows the overall view of the switch in the ON position with the cover cap cut.
- FIG. 2 shows a longitudinal section through the switch in the area of its switching mechanism; and
- FIG. 3 shows the cross section at the level of the rotary bearing of this switching mechanism.
- the switching mechanism composed of several lever and spring members 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 switch side and the electrothermal release element arranged on the right switch side. 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 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 arcing gases generated, 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.
- Ben additional signal switch of the device circuit breaker its toggle spring-loaded center contact 13 by the clamping body 5 of the switching mechanism (together with the unlatching lever 4 and the pivoting contact piece 6) on the same axis of rotation entrained driving lever 14 corresponding to the switch-on or switch-off or release movement of this Clamping body 5 mechanically brought into (snap) contact with one or the other fixed contact piece.
