Definitions
- the invention relates to an electromechanical switch according to the preamble of claim 1.
- Such an electromechanical switch is described in FR-Al-2 717 617.
- This has a contact carrier which can be pivoted by means of an actuating knob, on which movable contacts are pivotably held. These movable contacts are pressed against stops by springs.
- Above the upper ends of the movable contacts is a shaft which runs parallel to the pivoting axis of the contact carrier and carries an arm at the level of each contact, which arm is connected to the shaft in a rotationally fixed manner.
- Each of these arms has an end face on which the movable contact comes to rest when the contact carrier is swiveled from the OFF to the EI Position position and the movable contact is inhibited by the arm in its further movement.
- this solution has the disadvantage that the arms must be fixed on the shaft very precisely, which is associated with a corresponding manufacturing outlay.
- the aim of the invention is to avoid this disadvantage and to propose a switch of the type mentioned at the outset which can be easily produced regardless of the number of its switching paths and which nevertheless ensures a rapid build-up of the contact pressure when the switch is actuated by hand and moreover in simpler A switch with outer conductor switching paths and a neutral conductor switching path can be realized.
- each switch can be adapted to one as well as to the other installation habits with an otherwise completely identical construction of all switching paths. This eliminates the need to manufacture separate switches for one or the other installation habit.
- the development of the invention according to claim 2 allows switch combinations to be created in a simple manner.
- a preferred embodiment of the invention can thus be implemented in accordance with the characterizing features of claim 7 in a switch combination which has at least two switching paths each consisting of a movable and an associated fixed contact. The individual inhibiting parts are thus triggered independently of one another via the selector shaft.
- a particularly high wear resistance of the inhibiting part of the switch according to the invention can be achieved by the features of claims 3 and 4, respectively.
- the feature according to claim 5 has proven to be particularly useful. The invention will now be explained in more detail with reference to the drawing. Show: Fig. La and lb axonometric representations of a switch according to the invention with the cover removed, wherein according to the Fig.la and lb the neutral conductor switching path is arranged at a different end of an assembly of outer conductor switching devices.
- FIG. 2 is a plan view of the switch according to Fig.lb,
- FIG. 3 shows a section along line A-A of FIG. 2,
- Fig. 5 is a plan view of the movable contacts with the switching shaft and the inhibiting parts
- FIGS. La and 5 are exploded views of the arrangement of FIGS. La and 5 with key switch and operating lever,
- FIGS. 1b and 2, 3 and 4 are exploded views of the arrangement according to FIGS. 1b and 2, 3 and 4 with
- Fig. 12 is an exploded view corresponding to that of FIG. 10 but in another
- Fig. 13 is an exploded view corresponding to that of FIG. 11, but in another
- Fig. 14 and Fig. 15 views of the inhibiting part.
- the electromechanical switch according to the invention has a number of outer conductor switching paths corresponding to the intended use, corresponding to the current-carrying phases of the network, and a neutral conductor switching path. It can be provided for various switching functions. For example, it can be a conventional ON / OFF switch that is used solely for the manual establishment or interruption of an electrical connection.
- the main area of application for the switch according to the invention is circuit breaker technology, ie it is generally designed as a motor circuit breaker, circuit breaker or as a residual current circuit breaker.
- the number of three outer conductor switching paths shown here is not essential to the invention; depending on the specific application, the switch can always have more or less outer conductor switching gaps in combination with a neutral conductor switching gating.
- the structure and function of an outer conductor switching device A, in particular with reference to FIGS. 4, 6, 7 and 8, of a switch according to the invention is first described in more detail below. All outer conductor switching paths are constructed identically.
- the switch according to the invention has a housing 1 in which a switch lock 2 with an actuating lever 3 is held.
- the key switch 2 is coupled to a switching shaft 4, which is provided with receptacles 5 for movable contacts 6.
- mounting plates 22 are held in the housing 1, each of which accommodates axes 7 in recesses 21, on which inhibiting parts 8 are held pivotably independently of one another.
- Separators 9 are formed on these mounting plates 22, which protrude between two contact pairs, which contact pairs each comprise a fixed contact 10, which is held in the housing 1, and a movable contact 6, which is held in a receptacle 5.
- the fixed and movable contacts 10, 6 are connected to terminals 11 via electrical connections, not shown.
- Each inhibiting part 8 is designed as a lever-like component, at one end of which the pivot axis 7 and at the other end both an area which inhibits the movement of the movable contact 6 over a predetermined angle of rotation of the control shaft 4 and a cam which is moved by the control shaft 4 13 controllable area is formed.
- the inhibiting area is formed by a hook-like bend 14 of the end of the inhibiting part, which end of the hook lies in the longitudinal plane of the inhibiting part.
- a control surface 12 forming the controllable region is formed on a widening 24 which is directly adjacent to the hook-like bends 14 and projects beyond the longitudinal plane of the inhibitor. Between its two ends, the plastic inhibitor part has a crank.
- the hook-shaped bends 14 of the inhibiting parts 8 interact with extensions 15 (FIGS. 4 and 6) of the movable contacts 6.
- extensions 15 of the movable contacts 6 engage in the hook-shaped bends 14 of the inhibiting parts 8.
- the movable contacts 6 On both sides, the movable contacts 6 have aligned lugs 16 projecting from their contact carriers, which are held pivotably in grooves in the receptacles 5. These approaches 16 form the pivot axes of the movable contacts 6 (Fig. 7).
- the movable contacts 6 are supported by a spring 18, which surrounds a guide pin 19 held in the contact carrier of the movable contact 6, on a wall part 26 of the receptacle 5 and are preloaded against a stop 20 of the receptacle 5, the springs 18 in each case between the grooves 17 and the stops 20 are arranged. It is the extension 15 of the movable contact 6 is integrally formed on its end abutting the stop 20.
- the spring 18 is biased more and more because the one end or the extension 15 of the movable contact 6 from the hook-shaped bends 14 of the inhibiting part 8 is held while there is a lifting of the contact carrier of the movable contact 6 from the stop 20.
- the cam 13 also rotates, approaches the control surface 12 more and more until the cam 13 touches the control surface 12 and then the inhibiting part 8 is pushed away by the cam 13. This results in pivoting of the inhibiting parts 8 against the force of one of these springs 23 which bias against its inhibiting position (FIGS. 4, 12, 13).
- an inhibiting part 8 is pivoted to such an extent that its hook-shaped bend 14 disengages from the extension 15 of the movable contact 6 and this is pressed by the spring 18 against the fixed contact 10 with high force, as a result of which a quick build-up of the contact pressure results.
- the contacts 6, 10 are opened by corresponding actuation of the actuation lever 3 and the switch lock 2, which is coupled to the control shaft 4.
- the selector shaft 4 and its receptacles 5 are turned back, as a result of which the position shown in FIG. 2 is then reached.
- the individual outer conductor switching plugs A are constructed in the same way, in such a way that an inhibiting part 8 is assigned to each movable contact 6, the inhibiting parts 8 being pivotable independently about the axis 7 running parallel to the switching shaft 4.
- w identical outer conductor switching paths A can therefore be used, which are only to be arranged on a correspondingly long switching shaft 4. Therefore, only w outer conductor switching distances A are required to set up a switch.
- the realization of the neutral conductor switching path N of the switch according to the invention is shown, for example, in FIGS. 3 and 9.
- the structure of the neutral conductor switching path N corresponds that of an outer conductor switching path A, with the exception that no locking part is provided, the receptacle 21 for the shaft 7 of the locking part is left free.
- the extension 15 of the movable contact 6 rests on the stop 20 from the outset. If the selector shaft 4 is rotated, the receptacle 5 also rotates and presses the movable contact via the lugs 16 seated in the grooves 17 continuously in the sense of the rotation into the closed position with the fixed contacts 10.
- the otherwise identical structure of the switching devices allows the new neutral conductor switching devices to be arranged anywhere in the switching device package. This is preferably done, as shown in FIGS. 5, 10 and 13, at the end of the switch lock or, as shown in FIGS. 4, 11 and 12, at the free end of the overall circuit breaker structure, in each case corresponding installation habits to be observed.
