Description

I

  The invention relates to electrical engineering, and more specifically to relay automation.

A relay device is known that contains a base on which at least two electromagnetic relays are installed, each of which has its own magnetic system, and the core of electromagnetic relays are interconnected by mechanical means.

It is also known a relay device containing a base on which a particular node and electromagnetic relays are installed, each of which has its own magnetic system, with the core of electromagnets pivotally attached to the bracket that holds the adjusting mechanism with the pusher TzJ.

The known devices are of limited use due to the small number of logic functions performed.

The purpose of the invention is to expand the functionality.

The goal is achieved by the fact that in the relay device containing the base on which the contact node and the electromagnetic relays, each of which has its own magnetic system, are attached, two electromagnets are attached to a common bracket that holds the adjustment mechanism with a pusher. relay, and it is provided with guides with return springs that are mounted between the o & BjKtot bracket and base.

Claims (2)

The plunger is made in the form of a plate with rods, and the contact assembly is in the form of flat springs, while the plate rods are installed with the possibility of interaction with the said flat springs. 3 A microswitch is used as a contact node, and the pusher is designed as a profile cam. In FIG. 1 schematically shows the proposed device; in fig. view A in FIG. one; in fig. 3 is a view of B in FIG. one; in fig. 4 - device, option of use. The relay device comprises a base 1, on which two electromagnetic relays 2 are mounted with a bark 3 connected by means of hinges 4 with a bracket 5. The guides 6. with return springs serve to return the bracket 5 to the initial position. On base 1 a contact unit 7 is mounted in the form of a flat plate and is controlled by a rod 8 mounted on an insulating base 9, which is fixed on an adjusting screw 10 equipped with a lock nut 11. The profile cam 12 placed on an adjusting screw 10 is shown in FIG. . 4. On the base 1, a microswitch 13 is mounted, on which the profile cam 12 acts. The flat springs with contact aNm are marked with the numbers 14, 15, 16. The device operates as follows. The BAN function. The forbidden input can be either input XI or input X2. Then, when a signal is fed to input XI, the winding of the electromagnetic relay is energized and attracts measles 3. The anchor 3 using the hinge 4 increases the left end of the bracket 5, overcoming the resistance return in the left guide 6. At the same time which has a plate with rods 8, moves to the right and the left rod acts on the middle flat spring 15. The contacts of the flat springs 15 and 16 of the contact assembly 7 are closed and exit; flat spring 16 receive signal This signal disappears with the signal to the input X2 of the ban. Both rods now slide down along the flat springs of the contact assembly 7. The contact state assumes the initial position. 3 FUNCTIONALITY. When implementing this function, the output signal is removed from the flat spring 14. When signals appear at both inputs XI, X2, the cores of both electromagnetic relays are attracted, which ensures the translational movement of the rods 8 along the flat springs. The state of the contacts does not change. The output signal from the flat spring 14 appears when on. both inputs are simultaneously or missing signals. IMPLICATION function. There is no signal at the output from the flat spring 14 when a signal appears at input XI, and there is no signal at input X2. In this case, the left rod 8, when moved to the right, provides the breaking of the contacts of the flat springs 14 and 15 and, thus, the output signal from the flat spring 14 is absent. This function is also implemented if the inputs XI and X2 are swapped. RELIABLE FUNCTION. The output signal from the flat spring 16 is present only when the signals at the inputs XI and X2 do not match, i.e. when there is a signal at input XI and no input x2, at the output of the flat spring 16, a signal appears, and if there is a signal at the input. X2 and in the absence of it at the input XI, the output signal from the flat spring 16 is also present. In all cases, power is supplied to the flat spring 15 of the contact assembly 7. Claims An inventive relay device comprising a base on which a contact assembly and electromagnetic relays are installed, each of which has its own magnetic system, with the electromagnet core hinged to the bracket an adjusting mechanism with a pusher, characterized in that, in order to expand the function of oval possibilities, it uses two electromagnetic relays, and it is equipped with guides with return spring The lines are installed between the common bracket and the base. 2.
