Definitions
- the invention relates to an electromechanical switch according to the preamble of claim 1.
- Such an electromechanical switch is described in FR-AI -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 EL 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 operated manually. It is also the object of the invention to provide a switch in which the rapid build-up of the contact path functions perfectly even after a large number of circuits.
- Claim 7 be executed.
- 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.
- Fig. 1 is an axonometric view of a switch according to the invention with off
- FIG. 2 shows a section through a switch according to FIG. 1 with cover
- FIG. 3 is a plan view of the movable contacts with selector shaft and locking parts
- Fig. 6 is an exploded view of the arrangement of FIG. 3 with key switch and
- FIG. 7 shows an exploded view of the arrangement according to FIG. 3, however, with one opposite
- Fig. 6 offset viewing direction
- Fig. 8 and Fig. 9 views of the inhibiting part.
- the electromechanical switch according to the invention 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 the circuit breaker technology, i.e. it is usually designed as a motor circuit breaker, circuit breaker or - as shown in the drawings - as a residual current circuit breaker.
- the number of four pole sections shown here is not essential to the invention; depending on the specific application, the switch can have more or fewer pole sections.
- 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. Furthermore, mounting plates 22 are held in the housing 1, each of which accommodates axes 7 in Ausnelimungen 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 nooke 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 (FIG. 6) of the movable contacts 6 (FIG. 4).
- contacts 10, 6 When contacts 10, 6 are open, the extensions 15 of the movable contacts 6 engage in the hook-shaped bends 14 of the inhibiting parts 8 (FIG. 2).
- the movable contacts 6 have, on both sides, aligned lugs 16 projecting from their contact carriers, which are held pivotably in grooves in the receptacles 5. These lugs 16 form the pivot axes of the movable contacts 6.
- 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 against a stop 20 of the receptacle 5 biased, the springs 18 are each arranged between the grooves 17 and the stops 20.
- the projection 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. There is a pivoting of the inhibiting parts 8 against the force of a respective spring 23 biasing them against their inhibiting position (FIGS. 2, 6, 7).
- 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 switching paths are constructed in the same way and in such a way that an inhibiting part 8 is assigned to each movable contact 6, the inhibiting parts 8 being independent of the parallel to the Switch shaft 4 extending axis 8 are pivotable.
- w switching paths of the same design can therefore be used, which are only to be arranged on a correspondingly long switching shaft 4.
- no special, coordinated components or elaborate tuning or adjustment work is required.
