Description

The invention relates to electrical engineering and can be used to create electromechanical devices that require mechanical switching of a significant number of electrical contacts with minimum dimensions and the presence of special requirements, such as freeing the contact field after switching. A device for actuating contacts is known, comprising a plate, position sensors, a gear and a housing with an electric motor in it and a gear-worm; The main gearbox, the worm to which the axial movement is possible t13The disadvantage of the H3BjeeTHoro device is the impossibility of moving the clamping organ in the direction perpendicular to er (f displacement to ensure free access to the contacts, besides acting on the contacts the closing organ makes two movements: translational and most importantly, which is unacceptable in a number of cases. The purpose of the invention is the expansion of "four-site capabilities and improved usability. This goal is achieved by the fact that The contact points, containing a plate, position sensors, a gear rail and a housing with an electric motor placed in it and an eubchato-worm gearbox, the worm to which has the possibility of axial movement, is provided with horizontal guides for moving the housing, a spring-loaded contact clamp, the lock, the go are different l ynopcw and vertical guides, is tic tacial guides are located on the body, the rack and pinion is fixed on the plate, and the worm is connected via gear to the rack and kinematically in coupled with said spring-loaded clamp, a spring loaded clamp .ustanovlen GOVERNMENTAL a vertical guide, fixed to the locking plate with the Tew possible reaction with the L-shaped upo set, and secured to the spring-loaded abutment for contact nip. FIG. 1 schematically shows the proposed device, a general view of FIG. 2 is a kinematic diagram of the device; FIG. 3 - the same, side view. The device for bringing, into action, the contacts consists of a plate 1, with a position sensor 2 installed on it, a gear rack 3, a lock 4 and horizontal directional 5, in which case 6 moves with a ra: 5 gearbox in it and an electric motor 7, The gearbox contains gear wheels 8–13, tribes 14–17, worm gears 18 and 19, screws 20 and 21. In addition, the housing has a position sensor 22 and guide sleeves 23–26. In the guide bushes 23 and 26, vertical guides 27 and 28 are mounted, on which a clamp for contacts 29 with an L-shaped support 30 and a support sleeve 31 is fixed. The clamp for contacts 29 is pressed by springs 32 and 33 to the end surface of the washer 34 mounted on the end of the screw 21 using the bearing 35, the linings 36 and 37. Flags 38 and 39 are set on the housing 6 to trigger the position sensors. The device operates as follows. Before operation, the clamp for contacts 29 should be in such a position that the contact field is free and free access to it is provided (a necessary condition for being able to configure contacts). When the power is supplied, the motor 7 rotates and through the gearbox rotates the gear wheel 13, which engages with the gear rack 3. The housing 6 together with the clamp for the contacts 29 moves in the direction of the contact field. The movement of the housing 6 continues until the stop 30 attached to the contact clamp 29 reaches lock 4 and rests against its wall, while the gearbox branch extending from the screw 21 (containing gear wheels 12 and 13j 1Tribka 15 -17 and the worm gear wheel 19) stops, and the other reducer branch (containing 8-10 gear wheels, treadmill 14, worm gear 18 and worms 20 and 21) rotates, and the worm is screwed into the fixed worm gear 19, which performs the ro-nut in this case, makes a downward motion and the washer 34 presses against and the support tulku 31 clamp for contacts 29. The clamp for contacts together with the vertical guides 27 and 28 along the guide sleeves 25 and 26 moves strictly vertically downwards and ensures the simultaneous closure of the required number of contacts. The clamping movement for the contacts 29 continues until the flag 38 enters the slot of the induction position sensor 22 until it is triggered. When triggered, the position sensor 22 issues a signal to turn off the electric motor 7. After turning off the engine, the contacts remain in the closed position due to the self-braking properties of the worm pair. If it is necessary to open the contacts, a signal is sent to the reverse of the electric motor 7, the worm to 21 receives a rotation in the reverse direction and is unscrewed from the worm gear 19, making a forward movement vertically upwards. Instead, the spindle is moved upwards and pressed against the contacts 29, pressed by the springs 32 and 33 to the end surface of the washer 34 fixed on the worm 21. The upward movement of the worm 21 continues until the technical thrust until the worm 21 rests against the end of the guide sleeve 24, and the protrusion of the L-shaped anvil 30 does not come out of the groove of the lock 4, while the worm wheel rotates.

including in the work outgoing from the worm 21 branches of the reducer, and. the housing 6 together with the clamp for the contacts 29 is moved, freeing access to the contact field. This move

continues until the flag 39 enters the slot of the sensor 2 until it is activated. When triggered, the position sensor 2 generates a signal to stop the engine. So

Thus, the proposed device is again in the original polo and is ready to repeat the cycle.
