Definitions
- the invention relates to an actuating element for establishing a switching connection between a main switch and an auxiliary switch.
- actuating elements are particularly suitable for establishing an operative connection between a drive element of a main switch and an actuator of a microswitch.
- Equipment for low voltage switches can for example be a control, signal or
- Actuators of the above type are known in various ways. These are said to have excellent mobility and functionality even under difficult operating conditions, i.e. in the event of contamination or arcing-related deposits, and can also be easy to manufacture and assemble.
- the object of the invention is to provide an actuating element for establishing a switching connection between a main switch and an auxiliary switch make sure that the circuit connection works reliably.
- the invention is also intended to provide an actuating element that is simple to manufacture and easy to assemble in a main switch-auxiliary switch arrangement.
- FIG. 2 the main switch / auxiliary switch arrangement shown in FIG. 1 in a second switching state
- FIG. 3 shows a perspective illustration of the actuating element according to the invention.
- FIG. 4 is a perspective view of the main switch auxiliary switch arrangement equipped with the actuating element according to FIG. 3.
- an actuating element 3 for establishing a switching connection between a main switch 1 and an auxiliary switch 2 in a switch device such as e.g. a circuit breaker, built in.
- the main switch 1 consists of a contact system which is installed in a contact system or main switch housing 4 and can be actuated via a drive element 5.
- the contact system housing 4 consists of two housing half-shells 4a and 4b which are screwed, glued or riveted together after installation of the contact system elements belonging to the contact system.
- the main switch 1 and the auxiliary switch 2 are accommodated in two compartments of a switch housing 7, separated from one another by housing walls 7a, 7b, and are firmly positioned relative to one another.
- the auxiliary switch 2 is arranged such that a switching element or actuator 6 protrudes from its side facing downward in FIG. 1.
- the actuator is operatively connected to the drive element 5 with the interposition of the actuation element 3 and is pressed in by a switching movement of the drive element, as shown in FIG. 1, against the force of an actuation spring integrated in the auxiliary switch.
- the actuator 6 shown in FIG. 2 is reset by the force of the prestressed actuating spring.
- the actuating element 3 is formed in one piece and consists of an active section 3a and a lever section 3b which extends essentially at right angles to the active section 3a.
- the free end 3e of the lever section 3b is pivotally received in a recess formed in the contact system housing 4, so that the active section 3a can be pivoted between the drive element 5 of the main switch 1 and the actuator 6 of the auxiliary switch 2.
- the one-piece actuating element 3 furthermore has an elastically deformable section 3c which is designed as a projection and which can be tensioned by a pivoting or pendulum movement of the actuating element 3 directed upward in FIG. 1 against a stop 7 formed by the housing wall 7b.
- FIG. 1 shows the open position of the main switch 1, in which the drive element 5 is shown in this figure upper switch-off position.
- the drive element 5 is brought into this position by a force exerted by a lock of the switch which is large enough not only to press the actuator 6 into the auxiliary lock housing, but also to simultaneously pretension the elastic section 3c against the stop 7.
- actuating elements which establish an operative connection between a main switch and an auxiliary switch, are particularly susceptible to contamination due to their position in the switch and a movement impairment caused thereby.
- the actuating element is designed like a lever. Accordingly, a dirt-related movement hindrance at the bearing point, namely in the recess formed in the contact system housing 4, can be overcome more easily by the restoring force exerted by the actuator 6 in order to achieve the switching position of the auxiliary switch 2 shown in FIG. 2.
- Fig. 3 shows the special embodiment of the
- Actuating lever which is designed as a plastic injection molded part.
- the molded part is essentially U-shaped and has two legs 3b which can be inserted in a form-fitting manner with round thickenings formed at their ends 3e in corresponding recesses in the contact system housing 4 shown in FIG. 4.
- the section of the molded part connecting the legs 3b forms an actuating tongue 3d which, together with an L-shaped section 3f extending from one of its ends at right angles to the legs 3b, forms the active section 3a of the
- Actuating lever forms.
- the projection 3c acting as an elastic section is designed in the manner of a leaf spring which is held on one side on the operating lever.
- the actuating element shown in Fig. 3 can be mounted in the main switch-auxiliary switch arrangement shown in Fig. 4 in such a way that first the legs 3b engage around the housing wall of the main switch 1 with their thickened end portions 3e in the intended recesses and then the L-shaped section 3f is slidably lowered along a lateral recess 4c of the contact system housing 4 into the region of an opening 4d for receiving the drive element 5 by a downward pivoting movement in the figures.
- the lateral recess 4c with the opening 4d is formed not only in the housing half-shell 4a but also in the housing half-shell 4b.
- an actuating element 3 can also be used, which has an active section 3a on both sides of the actuating tongue 3d.
- the recesses for receiving the thickened end sections 3e have the same depth as the lateral recesses 4c and with them can be connected, thereby facilitating the manufacture of the housing half-shells. The latter is the case in the present embodiment in which not only the L-shaped section 3f but also the legs 3b with their thickened end sections 3e are recessed in the recess 4c.
- Actuating element can also have any other shape or
