    BACKGROUND OF THE INVENTION The invention relates to a switching device.
    It is known to provide a clutch device with a clutch device body, a work shaft element, a control shaft and a transmission system. In the opening operation, the work shaft element moves from the first position to the second position relative to the coupling device body. The transmission system operatively connects the guide shaft to the work shaft element. The transmission system has an actuator and one or more actuator springs connected between the clutch body and the actuator. In the opening operation, the actuator pivots from the first position to the second position relative to the clutch body by the energy delivered by the one or more actuator springs and pivots the work shaft element to the second position. Switching devices according to the prior art are described, for example, in EP 3 561 839 A1 and FI 20045026 (A).
    The problem with known switching devices is that devices with different rated currents have to use different transmission systems, so that the transmission systems of switching devices with higher rated currents are provided with more rigid actuator springs, because more reliable transmission of contacts rated for higher currents requires more reliable transmission.
    Brief description of the invention The object of the invention is to develop a switching device with which the above-mentioned problem can be solved. The object of the invention is achieved by a switching device which is characterized by what is stated in the independent protection claim. Preferred embodiments of the invention Q 25 are subject to epdisendent protection claims. N The invention is based on the fact that the clutch device has a booster system, S which assists the transmission system during the opening operation in turning the work shaft element 2 towards another position. The booster system has at least one booster spring and a booster drive member. During the opening operation, at least one booster spring N 30 delivers energy to the booster actuator, which is fixedly connected to the 2 actuators. The torque produced by the booster system is applied to the actuator S, thus assisting the transmission system in the opening operation. N The advantage of the switching device according to the invention is that identical actuating springs can be used in devices with different rated currents. The product family
    in low-current switchgear, the actuator springs alone are capable of delivering the force required to reliably move the contacts from one position to another, and high-current switchgear is provided with an booster system that provides additional force to move the contacts to the open position.
    The advantage of the coupling device according to the invention is that the individual forces exerted by the springs on the coupling device body are reduced, because the total force is distributed between the actuating springs and the booster springs. The distribution of forces at several points improves the durability of the coupling device body, especially in embodiments where the coupling device body is made of a plastic material.
    In one embodiment, the at least one booster spring of the booster system is spaced from the at least one drive spring in the direction of the pivot axis of the drive. In such an embodiment, the advantage is a small dimension of the coupling device in a direction perpendicular to the axis of rotation of the actuator. BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail in connection with preferred embodiments, with reference to the accompanying drawings, in which: Figure 1 shows a switching device according to an embodiment of the invention, seen obliquely from above; Fig. 2 shows a top view of the transmission system of the clutch device of Fig. 1; Fig. 3 shows the switching device according to Fig. 1 seen obliquely from below; Fig. 4 shows the coupling device according to Fig. 1, without the bottom part of the coupling device body, seen directly from below; | N | M 5 Fig. 5 shows the switching device according to Fig. 1 without the switching device body seen diagonally from above; Fig. 6 shows the switching device according to Fig. 1 without the switching device body E 30 - seen obliquely from below; © Fig. 7 shows the switching device according to Fig. 1 with the switching device S disassembled; Fig. 8 shows the switching device according to Fig. 1 with the switching device N going closed, seen directly from above; and Fig. 9 shows a cross-section of the switching device according to Fig. 1 at the point indicated in Fig. 8.
    DETAILED DESCRIPTION OF THE INVENTION The clutch device shown in Figs. 1 to 4 comprises a clutch device body 2, a work shaft element 4, a guide shaft 6, a transmission system and a booster system. The transmission system comprises an actuator 8 and two actuator springs 81,
    82. The booster system comprises a booster drive member 9 and two booster springs 91,
    92.
    The switching device is in the conductive state, i.e. the closed state, when the poles of the switching device are closed, and in the non-conducting state, i.e. the open state, when the poles of the switching device are open. The work shaft element 4 has a first position corresponding to the closed state of the clutch device and a second position corresponding to the open state of the clutch device. In Figures 1 to 7, the mechanism of the switching device is in the open state.
    The switching device shown in Figure 1 is a control device module which does not comprise contacts. The control module is adapted to be connected to one or more contact modules via a work shaft element 4.
    The working shaft element 4 of the coupling device is arranged to pivot between the first position and the second position relative to the coupling device body 2. The working shaft element 4 is adapted to move from the first position to the second position in the opening event, where the coupling device moves from closed to open. The guide shaft 6 is adapted to be connected to a drive handle (not shown in the figures) which is adapted for use by the user.
    The guide shaft 6 is adapted to pivot between the first position and the second position relative to the clutch body 2. The guide shaft 6 is adapted to control the pivoting of the work shaft element 4 so that the pivoting of the guide shaft 6 from the first position to the second position performs an opening operation.
    The transmission system operatively connects the working shaft o of the guide shaft 6 to the shaft element 4. It can be seen from Figure 2 that the two actuator springs are connected | between the coupling device body 2 and the actuator 8. Each of the drive springs 81, 82 is a & coil spring.
    n The actuator 8 is adapted to pivot between the first and second positions N30 - relative to the clutch body 2. The actuator 8 is adapted to co-operate with the work shaft element 4 to turn the work shaft element 4 towards the second position D during the opening operation by the energy s provided by the drive springs 81, 82. The actuator 8 pivots the work shaft element 4 from one position to another by being in contact with the work shaft element 4.
    > ”
    The pivot axes of the guide shaft 6 and the drive member 8 coincide.
    The axis of rotation of the working shaft element 4 is perpendicular to the axis of rotation of the drive member 8.
    The guide shaft 6 extends through the working shaft element 4, and the pivot axis of the guide shaft 6 intersects the pivot axis of the work shaft element 4.
    It can be seen from Figure 7 that the coupling device comprises coupling means with which the guide shaft 6 is connected to the actuator 8. The coupling means comprise helical spring means 5. Each actuator spring 81, 82 has a first low energy position, a second low energy position and a dead center position located in the low energy position. between positions.
    In the low energy positions, the actuator springs 81, 82 are substantially at rest.
    In the dead center position, the actuator springs 81, 82 have reached their maximum tension.
    Each actuator spring 81, 82 is adapted to pivot the actuator 8 between its first position and the second position, either towards the first position or towards the second position, depending on which side of the dead center position the actuator 8 is on.
    The energy required by each actuator spring 81, 82 to transition from the low energy positions to the dead center position results from rotating the guide shaft 6.
    Each actuator spring 81, 82 is adapted to transition from a dead center position to a first low energy position during the first actuator release event.
    The transmission system is adapted to turn the work shaft element 4 towards the second position during the opening operation by means of the energy given off by the first actuating operation.
    Each actuator spring 81, 82 is adapted to move from a dead center position to another low energy position in a second actuator release event.
    The transmission system is adapted to turn the work shaft element 4 towards the first position during the closing event by means of the energy given off by the second actuating event.
    In the closing operation, the work shaft element 4 is thus adapted to move from the second position to the first position.
    Figure 1 = shows the position of the guide shaft 6 in the second position in which the switching device is open.
    By comparing it to the position of the guide shaft 6 shown in Fig. 8, in which the coupling device E is closed and in which the drive springs 81, 82 are in the dead center position, it can be seen that the guide shaft 6 has turned almost 90 ° relative to the second position.
    The first position of the guide shaft 6 differs from the second position by 90 °. N The booster system is adapted to assist the transmission system S 35 during the opening operation to turn the work shaft element 4 towards the second position.
    It can be seen from Figures 3 to 7 and 9 that the booster system comprises two booster springs
    91,92 and the booster actuator 9. It can be seen from Figure 4 that the booster springs 91, 92 are connected between the coupling device body 2 and the booster actuator 9. The booster springs 91 and 92 are spaced from the drive springs 81 and 82 in the direction of the pivot axis of the guide shaft 6. In addition, the booster springs 91 and 92 are spaced 5 from the drive springs 81 and 82 in the direction of the axis of rotation of the drive 8.
    In an alternative embodiment, the booster system comprises two booster actuators located in succession in the direction of the pivot axis of the guide shaft, and at least one booster spring is connected to each booster drive.
    The transmission system of the clutch device thus comprises two drive springs 81, 82 and the booster system comprises two booster springs 91, 92. In alternative embodiments, the number of drive springs and booster springs differs from that shown in the figures.
    The booster drive member 9 is fixedly connected to the drive member 8 for transmitting torque between the booster drive member 9 and the drive member 8. The booster drive member 9 rotates simultaneously with the drive member 8. In one embodiment, one unitary component forms both a drive member and a booster drive member. In an alternative embodiment, the drive member and the booster drive member are separate components connected by a groove shaft connection.
    The booster springs 91, 92 are identical to the drive springs 81, 82. In alternative embodiments, the at least one booster spring is different in structure from the actuator spring (s).
    The booster system is adapted to apply torque to the actuator 8 during the opening operation by means of the energy delivered by the booster springs 91, 92. The actuator 8 is thus subjected to torque from both the transmission system and the booster system as the actuator springs 81, 82 and the booster AN springs 91, 92 provide energy for rotating the actuator 8. With the aid of the booster system, the opening event of the coupling device is achieved even more efficiently = without the need to increase the size of the actuating springs of the coupling device at any current levels in order to achieve a higher spring constant.
    E Each of the booster springs 91, 92, like the actuator springs © 81, 82, has a first low energy position, a second low energy position, and a dead-point position located between the low energy positions. The dead center of the booster springs 91 and N 92 occurs in the same position of the actuator 8 as the dead center of the actuator springs S 35 81 and 82.
    Each booster spring 91, 92 is adapted to transition from a dead center position to a first low energy position in the first booster actuation event. During the opening operation, the booster system is adapted to apply a torque to the actuator 8 by means of the energy delivered by each booster spring 91, 92 in the first booster actuator release event. The first booster actuation event is functionally equivalent to the first actuator trigger event.
    The booster system is adapted to assist the transmission system accordingly during the closing operation to turn the work shaft element 4 towards the first position. Each booster spring 91, 92 is adapted to move from a dead center position to another low energy position in a second booster actuation trigger event. The booster system is adapted to apply torque to the actuator 8 during the closing operation by means of the energy delivered by the booster springs 91, 92 in the second booster actuator release event. The second booster actuation event functionally corresponds to the second actuator actuation event.
    It can be seen from Fig. 7 that the clutch device body 2 comprises a cover part 21, a central part 22 and a base part 23. The drive member 8 and drive member springs 81, 82 are mounted in the center part 22 of the clutch device body 2. is releasably connected to the central portion 22. The guide shaft 6 extends through an opening formed in the central portion 22 of the switching device body 2 to the bottom portion 23 of the switching device body 2.
    It is obvious to a person skilled in the art that the basic idea of the invention can be implemented in many different ways. The invention and its embodiments are thus not limited to the examples described above but may vary within the scope of the protection requirements. O OF O OF O
