Definitions
- the invention relates to a remote control block with a magnet system according to the preamble of claim 1, which is particularly suitable for switching motor switches and circuit breakers on and off by means of a current pulse.
- an electromagnet acts with its plunger on a rocker arm which is mounted at its pivot point at a pivot point of the housing.
- the rocker arm carries a push rod, the end of which interacts alternately with the shoulders of a rocker on a switch, which is rotatably mounted on a fixed axis of the switch.
- the push rod is pivotally mounted on the rocker arm and pivots against the force of a spring in each course of movement in such a way that it alternately engages with one of the two shoulders of the rocker and the rocker in this way each time the electromagnet is actuated from a position in the other switches.
- the operation of this known switch with remote control is, however, relatively imprecise and prone to failure due to the pivotable push rod, which alternately springs onto one of the two shoulders of the rocker switch under spring action.
- the invention has for its object to make the operation of such a remote control block easier and safer.
- the remote control block 1 is designed in such a way that the driver 5 acts alternately on two plungers 8, 9 which are directed parallel to one another and are directed against the two arms 6a, 6b of the rocker 6 of the switching lock and are connected in opposite directions by a coupling rocker 7 and act between the two Tappets 8, 9 can be switched over such that each time the electromagnet 2 is actuated, it moves one of the two tappets 8, 9 into its working position and, after returning to its starting position or into a renewed actuation position, actuates the other tappet accordingly.
- each plunger 8a 9 a spring plunger 8b, 9b directed against the driver 5, which the wedge-shaped driver 5, which is slightly widened towards its free end, during its downward movement or when it falls back into a new starting position pivoted from engagement with the nose 8a or 9a of one plunger 8 or 9 into engagement with the nose 9a or 8a of the other plunger 8 or 9.
- the spring plunger 9b of the one plunger 9 is arranged at a distance 9d from the actuating lug 9a which is less than the distance 8d of the spring plunger 8b from the lug 8a of the other plunger 8.
- This smaller distance 9d of the spring plunger 9b has the result that in the RELEASED position of Fig. 3, in which the two plungers 8 and 9 are at a slightly different height, the driver 5 under the action of the spring plunger 9b on the OFF plunger 8 to the system comes and thus, when actuated by the rocker switch 4, always actuates the plunger 8, which causes the switch-off.
- leaf springs or the like can also be used.
- the two plungers 8, 9, which are connected to one another by the coupling rocker 7, are guided parallel to the actuation direction 2a of the electromagnet 2 transversely to the axis of rotation 6c of the rocker 6 of the switch lock in parallel longitudinal guides at a distance from one another, and the coupling rocker 7 is also on the housing 10 of the remote control block 1 between the two plungers 8, 9 pivotally mounted and engages with two end cross pins 7a, 7b in lateral guide slots 8c, 9c on the two plungers 8, 9.
- the remote control block according to the invention works as follows:
- the driver 5 is pressed against the ON plunger 9 by the spring plunger 8b which is laterally mounted in the OFF plunger 8 and engages under the lateral lug 9a of the plunger 9.
- the plunger 9 is then actuated by the movement of the rocker switch 4, acts on the rocker switch 6 of the key switch and switches the motor switch on.
- the tappet 8 is moved into the lower starting position by the coupling rocker 7 connecting the two plungers 8.
- the rocker switch 4 After de-energization of the electromagnet 2, the rocker switch 4 also returns to the starting position under the action of the helical compression spring 12.
- the driver 5 is pressed by the spring plunger 9b, which protrudes laterally from the plunger 9, again against the plunger 8, so that the plunger 8 is carried along with the next current pulse on the electromagnet 2 and immediately.
- the TRIPPED position is then again as described for FIG. 3 above.
