Definitions
- the invention relates to a circuit breaker for switching electrical circuits, in which the force applied by moving a rocker, a rocker arm or a rotary knob can be transmitted via a switch lock to a movable switching element which switches the circuit.
- Circuit breakers are manufactured in different sizes for switching different switching capacities.
- the overall structure of such a circuit breaker for example the position of the switch lock or various triggers, depends essentially on the maximum switching capacity.
- the switch must be actuated as centrally as possible on a control surface.
- the tilting member is operatively connected to a plunger of an actuating member such that the plunger is actuated each time it is actuated encounters a backdrop surface and thereupon a pivoting movement of the tilting member takes place in its opposite position.
- An actuator is assigned to the switching mechanism, the rocker element cooperating both with the contact spring and with the actuator which is rotatably arranged in the switch housing between the rocker element and the freely movable end of the contact spring.
- the switching mechanism can be optionally changed with the help of the actuator so that it can be used either as a switch or as a button. With this switching mechanism, however, different sizes of circuit breakers cannot be compensated for.
- an electrical interrupter switch which has a tiltable or slide-like adjustable actuating button for the optional actuation of two movable contacts. This can be moved back and forth between an initial position, which corresponds to the open position of the two movable contacts with respect to the fixed contacts, and two successive positions, which are associated with the closing of one or both movable contacts with the fixed contacts.
- the contact is associated with an elastic locking element which interacts with the actuating button for determining the positions of the operating button, the elastic locking element being formed by an elastic tongue which is connected to a carrier for the fixed contacts.
- the known breaker switch has different actuators; however, it is also not possible to compensate for different sizes of circuit breakers.
- the invention has for its object to design a circuit breaker of the type mentioned so that the expensive designs of different switch locks are avoided.
- This object is achieved according to claim 1 in that the switch lock has the same basic equipment for different sizes of the circuit breaker, which can be adapted to the requirements for the different sizes by exchanging, omitting or adding different individual components.
- the rocker can be exchanged for a rocker arm.
- the rocker can be exchanged for a toothed rocker. Furthermore, the rocker can be exchanged for a toothed rocker with counter wheel and rotary knob.
- a drive shaft can be inserted between the tooth rocker and the counter wheel.
- the advantages achieved by the invention are, in particular, that expensive special designs of different switch locks are avoided, and that a basic equipment suitable for differently sized circuit breakers, which can be manufactured more cheaply, can be used in large numbers.
- FIG. 1 shows a schematic representation of three circuit breakers of different sizes
- FIG. 2 shows a schematic representation of the control surfaces of three circuit breakers of different sizes
- IG 3 is a perspective view of a switch lock with a rocker
- IG 4 is a perspective view of a switch lock with a toothed rocker
- IG 5 is a perspective view of a switch lock with a toothed rocker, a counter wheel and a rotary toggle
- IG 6 is a perspective view of a switch lock with a tooth rocker and a drive shaft and
- FIG. 7 shows a perspective view of a switch lock with a tooth rocker, a drive shaft, a counter wheel and a rotary toggle.
- FIG. 1 shows a schematic representation of three differently sized circuit breakers with different triggers 7, 8 for short circuit and for overload, with either no or different individual components between a switch lock 1, each with the same basic equipment and an actuating element, namely a rocker 2 or a rotary knob 4 how a toothed rocker 3 with a counter wheel 5 or a drive shaft 6 with a counter wheel 5 are inserted.
- FIG. 2 shows a schematic representation of the control surfaces of three circuit breakers of different sizes, the smallest version using a rocker or a rocker arm 2 as the actuating element, while for the two larger versions there is a rotary toggle 4 suitable for larger forces.
- the switch lock shown in Figures 3 to 7 always has the same basic equipment. This consists essentially of two parallel to each other, forming a housing-forming boards 9, 10, between which apart from a torsion spring 16, a lock 17 and other individual parts the plates 9, 10 connecting bolts 11, 12 extend on which a ratchet lever 14 and a shift lever 15 are rotatably mounted.
- a further bolt 13 also serves as a pivot bearing in FIGS. 3 to 7, but for different individual components, namely in FIG. 3 for a rocker or a rocker arm 2 and in FIGS. 4 to 7 for a toothed rocker 3, which in FIG Counter wheel 5 is coupled to a rotary knob 4.
- the bolt 13 serves as a bearing for a toothed rocker 3 and for a drive shaft 6 coupled to it, while in FIG. 7 a counter wheel 5 and a rotary toggle 4 are additionally arranged.
