Description

The claimed utility model relates to electromagnetic apparatuses, in particular, to alternating and direct current indicating relays and can be used for signaling (visual information) of an emergency condition in direct and alternating current circuits of protection, automation, control and signaling systems.

The closest technical solution (prototype) is a technical solution (USSR Author's Certificate No. 1612336, Н01Н 51/30, publ. 07.12.90, Bull. No. 45), comprising a housing with a hole, an electromagnet in the form of a coil with a core, a guide, contacts, a spring-loaded element installed in the housing, a rotary anchor mounted on a support, a latch, contacts, springs.

Disadvantages: low shock resistance of the device, because the direction of movement of the armature and the direction of pressing the button coincide with the direction of impact when closing the door of the cabinet of electrical equipment, on which the indicator relay is installed.

The technical problem solved by the creation of a new technical solution is that during operation, when closing the door of the electrical equipment cabinet, on which the indicator relay is mounted, false relay operation very often occurs, which is associated with low shock resistance of the device.

The technical result of the claimed utility model is the creation of a pointing relay with increased shock resistance when exposed to shock and vibration loads during the operation of electrical equipment.

The technical result is achieved in that the indicator relay, comprising a housing with a hole, an electromagnet in the form of a coil with a core, a guide, contacts, a spring-loaded element mounted in the housing, a rotary armature mounted on a support, a latch, contacts, springs, and the housing opening is made in in the form of central perpendicular cutouts of a rectangular shape, and an element spring-loaded with a wire spring in the form of a traverse with an external element of manual switching is parallel to the core of the electromagnet and made with the possibility of translational movement in the guides of the housing along its front surface, the rotary anchor is made perpendicular to the front surface of the housing and is installed in the cutouts of the printed circuit board, to which a wire spring is fixed with the possibility of interaction with one internal protrusion of the crosshead, at least one additional internal protrusion of which made with the possibility of interaction with the contacts located on the printed circuit boards, in the holes of which the axis is located, on which is made with the possibility of rotation of the latch with protrusions, a flat return spring mounted on the printed circuit board, is configured to interact with the rotary armature through its bent element, and all these elements are made in the housing, consisting of two mating parts, fixed to each other with mechanical fasteners. At the same time, around the cutouts on the front surface of the housing are external curly protrusions. In this case, the guide body is made integral with it. In this case, one protrusion of the latch is made with the possibility of interaction with the traverse, and the other protrusion is made with the possibility of fixing the rotary anchor through the anchor bracket attached to the rotary anchor. In this case, the guide bodies are parallel to the core of the electromagnet in the assembled state of the device.

New significant distinguishing features of the claimed technical solution are the following features:

- the implementation of the holes in the form of central perpendicular cutouts of a rectangular shape;

- the implementation of a spring-loaded wire spring element in the form of a traverse with an external manual switching element located parallel to the core of the electromagnet and made with the possibility of translational movement in the guides of the housing along its front surface;

- the execution of the rotary anchor perpendicular to the front surface of the housing and installed in the cutouts of the printed circuit board;

- the implementation of a wire spring fixed to the printed circuit board with the possibility of interaction with one internal protrusion of the traverse, at least one additional internal protrusion of which is configured to interact with contacts located on the printed circuit boards;

- execution in the holes of the printed circuit board axis, which is made with the possibility of rotation of the latch with the tabs;

- the implementation of a flat return spring mounted on a printed circuit board with the ability to interact with a rotary armature through its bent element;

- the implementation of all these elements in a housing consisting of two mating parts, fixed to each other using mechanical fasteners.

The combination of new significant distinguishing features with the features known from the prior art is sufficient to obtain the technical result provided by the utility model, which consists in creating a device having increased shock resistance when exposed to shock and vibration loads during the operation of electrical equipment.

The indicator relay 1 (Fig. 1, 3) contains a housing 2 (Fig. 1, 2) in the form of a rectangular parallelepiped, which consists of two paired parts 3, 4 (Fig. 3), fixed to each other in an assembled state using mechanical fasteners (any standard screw) 5 (Fig. 1, 2). In the frontal surface 6 of the housing 2 there are central cutouts (vertical and horizontal) 7, 8 (Fig. 3) of a rectangular shape, perpendicular to each other. Around these central (vertical and horizontal) cutouts 7, 8 there are outer curly protrusions 9, 10, made opposite to each other on the mating parts 3, 4. Guides (protrusions-stops) 11 (Fig. 1, 2) and 12 (Fig. 4), made integral with the housing 2 (Fig. 1, 2), i.e. which are part of it, are located on the inner surfaces 13 (Fig. 1, 2) and 14 (Fig. 4) of the mating parts 3, 4 (Fig. 3) of the housing 2 (Fig. 1, 2) from the side of its front surface 6 and are parallel the core of the electromagnet 15 in the assembled state of the device.

The following structural elements are placed in the housing 2: an electromagnet 15, containing two coils 16 with cores 17 and a base 18, which together form a U-shaped magnetic system, and there is also a rotary armature 19, swinging in supports 20 made parallel to the base 18. Anchor 19 is located perpendicular to the front surface 6 of the housing 2 in the assembled state of the device. Traverse 21 is installed in the guides 11 (Fig. 1, 2) and 12 (Fig. 4) of the housing 2 (Fig. 1, 2) and has the possibility of translational movement in a direction that is perpendicular to the location of the rotary armature 19. Traverse 21, parallel to the core the electromagnet 15 has the following structural elements, namely: external structural elements - the outer element 22 of the manual switching of the beam 21, made with the possibility of translational movement in the vertical (Central) cutout 7 (Fig. 3) of the housing 2 (Fig. 1, 2) and intended d I bring the index operator switch the cocked position; a groove 23 of a rectangular shape (to accommodate the protrusion 35 of the latch 24 in it), made in the traverse 21 perpendicular to the direction of its translational movement; on the front surface of the yoke 21 there is a signal strip 25 (Fig. 3) of a contrasting color, which by its color indicates that the indicator relay has tripped and is in the position when the contacts, for example, are open as indicated in FIG. 2; internal structural elements include: two internal protrusions 26, 26a (Fig. 1, 2, 4) are located at a distance from each other by means of which the crosshead 21 acts on two contacts 27, which are located on the printed circuit boards 29 (Fig. 1, 2) , 30 (Fig. 4), i.e. their ends are attached to them; the inner protrusion 31 (Fig. 1, 2), which is influenced by a wire spring 32, which moves the yoke 21 to bring the relay to the actuated position when the contacts, for example, are open as shown in FIG. 2. The outer element 22 (Fig. 1, 2) of the manual switch of the yoke 21 is made in the middle of the signal strip 25 (Fig. 3) of a contrasting color on the yoke 21 (Fig. 1, 2).

The outer curly protrusions 9, 10 (Fig. 3) of the front surface 6 (Fig. 1, 2) of the housing 2, located around the central (vertical and horizontal) cutouts 7, 8 (Fig. 3), serve to prevent erroneous switching of the beam 21 ( Fig. 1, 2) by the operator in the process of servicing electrical equipment.

The horizontal (central) cutout 8 (Fig. 3) is intended for visualization by the operator of the signal strip 25 of the contrasting color of the yoke 21 (Fig. 1, 2) when the indicator relay is brought to an excited position (when the contacts, for example, are open as shown in Fig. 2) .

The vertical (central) cutout 7 (Fig. 3) is designed to move the outer element 22 (Fig. 1, 2) to manually switch the yoke 21.

To the printed circuit board 30 (Fig. 4), a wire spring 32 (Fig. 1, 2) is perpendicularly attached. An anchor bracket 33 is attached to the rotary anchor 19, which is located on the side of the contact arrangement 27. Between the anchor bracket 33 and the traverse 21, a latch 24 is mounted on the axis 34, which is located between the printed circuit boards 29 (Fig. 1, 2) and 30 ( Fig. 4) and is attached to them, because there are corresponding holes in the printed circuit boards (not shown in FIG.). The latch 24 (Fig. 1, 2), made with the possibility of rotation on the axis 34, has two protrusions, where one protrusion 35 is made to interact with the traverse 21, and the other protrusion 36 is designed to fix the rotary armature 19 through the anchor bracket 33 attached to rotary anchor 19. The printed circuit boards 29 (Fig. 1, 2) and 30 (Fig. 4) are interconnected by means of bent elements 37, 38 (Fig. 1, 2) of the base 18 and supports 20, respectively. The supports 20 and the base 18, made of a U-shaped (due to the bent elements 37, 38), fix the position of the electromagnet 15 in the claimed device. On the printed circuit board 29, a flat return spring 39 is installed, which is configured to interact with the rotary armature 19 through its bent element 40 to bring the armature 19 into a cocked state. The rotary anchor 19 is fixed in the grooves (not shown in FIG.) Of the printed circuit board 29 by means of bent elements 38 of the support 20 with the possibility of its rotation in these grooves (not shown in FIG.) Of the printed circuit board 29. Terminal blocks 41 (FIG. 3) made attached to the printed circuit boards 29 (Fig. 1, 2) and 30 (Fig. 4), are designed to connect the wires.

The device operates as follows.

The assembled indicating relay is mounted on the door indicated in FIG. 1, 2, 4 of the electrical cabinet in such a way that its front surface 6 coincides with the inner surface of the door of the electrical cabinet, and the arrow 42 made on the outer surface of the beam 21 (Fig. 3), located perpendicular to the signal strip 25 (Fig. 1, 2, 3) contrasting color, was directed vertically downward. When the operator manually moves the beam 21 (Fig. 1, 2) using the outer manual switching element 22 located in the vertical (central) neckline 7 (Fig. 3) along the electromagnet 15 (Fig. 1, 2) in the direction of the rotary armature 19 , the latch 24, connected to the traverse 21 by means of a figured protrusion 36, is rotatable around the axis 34 on which it is mounted, and is fixed by an anchor bracket 33 attached to the rotary anchor 19. At this moment, the rotary anchor 19 is rotated (with offset) position under the influence of a plos second return spring 39 with respect to the cores 17 of an electromagnet 15. Contacts 27 are at this time in the closed position, i.e. the device is cocked up and ready to go. In this case, the strip of contrasting color of the signal part 25 (Figs. 1, 2, 3) of the traverse 21 (Figs. 1, 2) is not visualized, because it is located outside the horizontal (central) cutout 8 of the front surface 6 of the housing 2.

When applying a supply voltage (relay excitation) to the windings of the coils 16, the rotary armature 19 is attracted to the poles of the cores 17 of the coils 16, and the anchor bracket 33 attached to the rotary armature 19 disengages from the protrusion 36 of the latch 24, the protrusion 35 of which is rectangular the groove 23 of the yoke 21. The spring 21 of the yoke 32, translationally moving parallel to the core 17 of the electromagnet 15 along the front surface of the housing 2 in the direction from the rotary armature 19, acts on the closed contacts 27 and their protrusions 26 opens them.

When removing the supply voltage from the windings of the coils 16, the rotary armature 19 returns to its original state under the action of a flat return spring 39. The contrasting color strip of the signal part 25 (Figs. 1, 2, 3) of the beam 21 (Figs. 1, 2) is visualized in horizontal ( central) neckline 8 of the front surface 6 of the housing 2.

To re-bring the indicator relay into a charged state, the operator manually moves the yoke 21 using the external manual switching element 22 along the core of the electromagnet 15 in the direction of the rotary armature 19 and the contrasting color of the signal part 25 (Fig. 1, 2, 3) of the yoke 21 will not visualized in the horizontal (central) cutout 8 of the housing 2.

When servicing the door of the cabinet of electrical equipment, in which the declared indicator relay is installed, shock loads act on it in a direction that is perpendicular to the direction of movement of the rotary armature 19 (i.e., when the door of the cabinet of electrical equipment is closed, the direction of the shock load does not coincide with the direction of movement of the rotary armature 19) , which ensures the stability of the claimed device to the effects of shock loads.

In contrast to the prototype, where the direction of movement of the rotary armature and the direction of pressing the button coincide with the direction (vector) of the impact on the indicator relay when closing the cabinet door of the electrical equipment, on which the indicator relay is installed (i.e., the armature moves in the direction of the shock load when closing the cabinet door electrical equipment, because the working elements of the prototype: button, guide, spring, contact, return spring, retainer are made in the area in front of the rotary armature), in the proposed technical solution is directed (vector) movement of the armature and traverse (instead of the button) with an external element of manual switching moving perpendicular to the direction (vector) of the impact when closing the cabinet door of the electrical equipment to which the declared indicator relay is installed (i.e. the armature moves in the direction perpendicular to the direction of the shock load, and the direction of movement of the traverse parallel to the front surface of the housing because the working elements of the device: traverse, guides, wire spring, contacts, retainer, axis are made in zone located on the side of the electromagnet), which ensures stable operation of the device under shock loads (shock resistance of the device).

Unlike the prototype, where the rotary anchor is parallel to the front surface of the body (coincides with the front surface of the body) and the direction of movement of the armature coincides with the direction of movement of the shock load, which negatively affects the impact resistance of the prototype, in the claimed technical solution, the rotary anchor is located perpendicular to the front surface of the body, along which the traverse moves with the external element of manual switching, which increases shock resistance (reliability from false response) of the claimed device, as the direction of movement of the armature is perpendicular to the direction of the shock load when closing the door of the cabinet of electrical equipment.

In contrast to the prototype, where the design of the indicator relay contains a button, which, when the door of the electrical cabinet is closed, moves under the influence of the shock load in the direction of the shock vector (false operation of the device occurs), because the direction of movement of the button is perpendicular to the front surface of the body of the pointing relay prototype, in the proposed technical solution to eliminate such movement when closing the door of the cabinet of electrical equipment in the claimed design uses a beam, moving perpendicular to the direction / vector of the shock load (i.e., the beam moves only along the front surface case inside the guide rails of the case), so the possibility of spontaneous movement of the traverse under the air ystviem shock load to provide enhanced impact resistance device.

Due to the fact that the main structural elements of the claimed device are located in its lateral part, therefore, the coil springs that are used in the prototype are replaced in the proposed indicator relay with a flat and wire spring.

The set of new significant structural features of the claimed technical solution is made such that it is possible to position the traverse with the external manual switching element made on it so that the shock load does not affect it upon impact, because the traverse is located perpendicular to the direction of the shock load when closing the door of the cabinet of electrical equipment, and also due to the fact that the traverse is made with the ability to move only along the front surface of the housing.

All components of the claimed technical solution are connected (fixed) among themselves by assembly operations, i.e. are in a functional and constructive unity, which ensures the achievement of the claimed technical result to solve the problem.

The proposed technical solution, having constructive unity, implements a general functional purpose (functional unity).

The implementation of the proposed utility model allows to solve the claimed technical problem and ensure the achievement of the claimed technical result.

In the prior art, no analogue was found, characterized by features identical to all the essential features of the claimed utility model.

The applicant tested (tested) the proposed device, which confirmed the purpose, feasibility and efficiency, and therefore the claimed utility model meets the patentability condition “industrial applicability”.
