Abstract

This invention relates to electrical circuit switching devices. The purpose of the invention is to increase the reliability and expand the logical capabilities of the device. When a polarized control signal is applied to the outputs for connecting the control signal, the bimorph piezoelectric element, i.e. the movable contact part (CD) 2 remains in the initial position due to its blocking by ferromagnetic movable CDs 9 and 10, as a result. Logic operation NO is performed. When the control polarized signal is removed from the terminals of relay CD 2, it is also in the initial state. In the presence of a magnetically adjustable flow, the source of which can serve as permanent magnets or control coils wound oppositely at the ends of movable CDs 9 and 10, movable CDs 9 and 10 deviate from each other, breaking off electrical contact with each other, thus forming a ME new electrical contacts between fixed CD 11 and 12 and movable CD 9 and 10. With a control polarized electrical signal, the mobile CD 2 will deform, forming an electrical circuit between electrical contact 5 located on mobile CD 2 and fixed CD 8. When removing the control magnetic flux, mobile CD 9 and 10 are returned to their original position by the action of elastic forces; electrical circuits between CD 11, 10) and CD 9, 12, to form an electrical AA with S (L el 35

the circuit between CD 9 and 0. Due to the curved ends of CD 9 and 0, the return to the initial state of the mobile CD 2 will become impossible and the electrical contact between the mobile CD 2 and the fixed CD 8 will remain, regardless of

The invention relates to electrical engineering, in particular to switching devices of electrical circuits, and can find application in automation systems, telemechanics and communication, where reliable switching, performing logic operations, blocking electrical circuits are required.

The purpose of the invention is to increase the reliability and expand the logical capabilities of the device.

Figure 1 shows the relay, a longitudinal section; figure 2 - section aa in Fig .; Figs. 3 and 4 show the state of the relay in the presence of a control magnetic flux with the subsequent supply of a polarized control electrical signal; in FIG. 3, the state of the relay with a complex combination of a sequence of control signals.

The relay contains a sealed cylinder 1, a movable contact part 2 located in it, made in the form of a dimorphic piezoelectric element, connected to terminals 3 and 4 for connecting a control signal and an electrical contact 5 placed on it, connected with current-conducting tracks 6 with output 7, the conductive track 6 being insulated from the bimorph piezoelectric element stationary ferromagnetic contact piece 8, and the said movable contact al 2, made in the form of a bimorph piezoelectric element and stationary ferro agnitna contact piece 8 are mounted at opposite ends of the cylinder and forming between them an zamy- repentieth contact pair. Perpendicular to the longitudinal axis of the sealed cylinder I, there are movable ferromagnetic contact parts 9 and 0 which form a disconnecting contact pair between them, and their loose ends or no control electrical signal. Depending on the sequence of supplying various kinds of control signals, eight different 1X combinations are possible, 1 3.p. f-ly, 5 ill.

The rings are figured and cover the movable contact part 2 in such a way that they form a lock type connection between them. The relay can be equipped with two additional stationary ferromagnetic contact parts 11 and 12, which form closing contact pairs with movable ferromagnetic contact parts.

The device works as follows.

When a polarized control signal is applied to pins 3 and 4 for connecting a control signal, the bimorph piezoelectric element, i.e. The movable contact part 2 remains in the initial position due to its blocking by movable ferromagnetic contact parts 9 and 10, the logical operation is NO. When removing the control polarized signal from pins 3 and 4, the relays are also in the initial state (Fig. 2). Further, in the presence of a magnetic flux, the source of which can be permanent magnets or control coils wound oppositely at the ends of movable ferromagnetic contact parts 9 and 10 (not shown), movable ferromagnetic contact parts 9 and 10 deviate from each other, the breakage electrical contact between themselves (contact parts 9 and 10), thereby forming a new electrical contact between stationary ferromagnetic contact parts 11 and 12 and movable ferromagnetic contact parts 9 and 10, respectively (Fig. 4). If there is a controlling polarized electrical signal. G1A at terminals 3 and 4, the movable contact part 2 will deform, forming an electrical circuit between electrical contact 5 (terminal 7) and the stationary

ferromagnetic contact part 8 (figure 5). When the control magnetic flux is removed, the movable ferromagnetic contact parts 9 and 10, under the action of elastic forces, return to their initial position, breaking the electrical circuits between contact parts 11 and 10 and between contact details 9 and 12, forming an electrical circuit between parts 9 and 10. Due to the shaped ends of the contact parts 9 and 10, the resetting of the movable contact of part 2 becomes impossible, and the electrical contact between the movable contact of part 2 and the non-movable ferromagnetic contact part 8 remains independent on the presence or absence of the control electric polarized signal at terminals 3 and 4 of the control signal. Thus, eight different combinations of relay operation are possible depending on the sequence of supplying various types of control signals.
