Description

Technical Field

[0001] This utility model relates to the field of relay technology, and more specifically, to a switching type magnetic latching relay. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the input quantity changes to a specified degree. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. In fact, it is an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in the circuit. In daily life, a switching type magnetic latching relay is needed.

[0003] Currently, the two circuits of a relay require two relays for control, which not only increases the cost for users and manufacturers, but also reduces the synchronization of the two relays, reduces the reliability of the circuit, and affects the overall normal operation and cost of the relay.

[0004] Therefore, those skilled in the art have provided a switching type magnetic latching relay to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a switching type magnetic latching relay, including a base, and further comprising:

[0006] The coil assembly is disposed inside the base;

[0007] An armature structure is disposed on the outside of the coil assembly;

[0008] A pusher plate is disposed on the base;

[0009] The left stationary plate, the right stationary plate, and the moving plate are all installed inside the base, and the left stationary plate and the right stationary plate are respectively riveted to the inside of the base.

[0010] The left three-arch plate and the right three-arch plate are respectively riveted to both sides of the outer wall of the moving plate, and the left three-arch plate and the right three-arch plate are respectively riveted to the inside of the moving plate and the right active contact.

[0011] An auxiliary contact assembly is disposed inside the base.

[0012] As a further improvement to this technical solution, the coil assembly includes a frame fixedly installed inside the base, the outside of the frame is provided with enameled wire, and the inside of the frame is provided with two yokes.

[0013] As a further improvement to this technical solution, the auxiliary contact assembly includes a left auxiliary moving spring, a right auxiliary moving spring, and an auxiliary stationary spring, which are respectively disposed inside the base. The left and right auxiliary moving springs are respectively provided with a left auxiliary moving contact and a right auxiliary moving contact inside the base, and the auxiliary stationary spring is symmetrically provided with auxiliary stationary contacts inside the base.

[0014] As a further improvement to this technical solution, the upper surface of the pusher is provided with a movable groove for the left three bow plates and the right three bow plates to move, and the bottom of the pusher is provided with a movable groove for the left auxiliary moving spring plate and the right auxiliary moving spring plate to move.

[0015] As a further improvement to this technical solution, a protective outer shell is fixedly installed on the outside of the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this type of magnetic latching relay, the coil assembly and auxiliary contact assembly generate a magnetic field when the enameled wire is energized, causing the armature structure to swing the push plate. Since the left and right three-arm plates are riveted to both ends of the moving plate, and the moving plate is installed between the left and right stationary plates, the push plate has two slots. When the push plate swings, it can cause the left and right three-arm plates to move in the same direction. An auxiliary contact structure is also provided, with an auxiliary stationary spring located between the left and right auxiliary moving springs. The push plate also has two slots that cause the left and right auxiliary moving springs to move in the same direction. When the left stationary contact inside the left stationary plate closes with the left active contact... When the right stationary contact inside the right stationary plate is disconnected from the right active contact, the left auxiliary contact will disconnect from the auxiliary stationary contact, and the right auxiliary contact will close with the auxiliary stationary contact. When the left stationary contact inside the left stationary plate is disconnected from the left active contact, the right stationary contact inside the right stationary plate will close with the right active contact. At this time, the left auxiliary contact will close with the auxiliary stationary contact, and the right auxiliary contact will disconnect from the auxiliary stationary contact. This is a changeover relay with an auxiliary contact structure. In this way, the synchronization of the two main circuits is more reliable. At the same time, under the monitoring of the auxiliary contact structure, the safety and reliability of the circuit are enhanced, the cost is reduced, and the efficiency of maintenance and replacement of the main circuit is improved.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 As shown, this embodiment provides a switching type magnetic latching relay, including a base 2, characterized in that it further includes:

[0026] The coil assembly is located inside the base 2;

[0027] Armature structure 7 is located on the outside of the online package assembly;

[0028] Push plate 6 is mounted on base 2;

[0029] Left stationary plate 8, right stationary plate 10 and moving plate 12 are all installed inside the base 2. Left stationary contact 9 and right stationary contact 11 are riveted to the inside of left stationary plate 8 and right stationary plate 10 respectively.

[0030] The left three-arch plate 14 and the right three-arch plate 21 are respectively riveted to both sides of the outer wall of the moving plate 12. The left three-arch plate 14 and the right three-arch plate 21 are respectively riveted to the left active contact 13 and the right active contact 22.

[0031] The auxiliary contact assembly is located inside the base 2.

[0032] The working principle is as follows: When the enameled wire 4 is energized, a magnetic field is generated, causing the armature structure 7 to drive the pusher 6 to swing. Since the left three-arched plate 14 and the right three-arched plate 21 are both riveted to both ends of the moving plate 12, and the moving plate 12 is installed between the left stationary plate 8 and the right stationary plate 10, the pusher 6 has two slots. When the pusher 6 swings, it can drive the left three-arched plate 14 and the right three-arched plate 21 to move in the same direction. In addition, there is an auxiliary contact structure. The auxiliary stationary spring 19 is located between the left auxiliary moving spring 15 and the right auxiliary moving spring 17. At the same time, the pusher 6 has two slots that drive the left auxiliary moving spring 15 and the right auxiliary moving spring 17 to move in the same direction. When the left stationary contact 9 inside the left stationary plate 8 closes with the left active contact 13, the right stationary contact 9 inside the right stationary plate 10 closes. When contact 11 disconnects from the right active contact 22, the left auxiliary contact 16 disconnects from the auxiliary stationary contact 20, and the right auxiliary contact 18 closes with the auxiliary stationary contact 20. When the left stationary contact 9 inside the left stationary plate 8 disconnects from the left active contact 13, the right stationary contact 11 inside the right stationary plate 10 closes with the right active contact 22. At this time, the left auxiliary contact 16 closes with the auxiliary stationary contact 20, and the right auxiliary contact 18 disconnects from the auxiliary stationary contact 20. This is a changeover relay with an auxiliary contact structure. By controlling two sets of main circuits in this way, the synchronization is more reliable. At the same time, under the monitoring of the auxiliary contact structure, the safety and reliability of the circuit are enhanced, the cost is reduced, and the efficiency of maintenance and replacement of the main circuit is improved.

[0033] In order for the relay to operate normally, the coil assembly includes a frame 3 fixedly installed inside the base 2. The frame 3 is provided with an enameled wire 4 on the outside and two yokes 5 inside the frame 3. Through the arrangement of the frame 3, the enameled wire 4 and the yokes 5, the relay can be used normally. At the same time, when the enameled wire 4 is energized, the magnetic field generated can cause the armature structure 7 to drive the push plate 6 to move synchronously.

[0034] Considering that the relay requires control of two main circuits, the auxiliary contact assembly includes a left auxiliary moving spring 15, a right auxiliary moving spring 17, and an auxiliary stationary spring 19, respectively located inside the base 2. The left and right auxiliary moving springs 15 and 17 each have a left auxiliary moving contact 16 and a right auxiliary moving contact 18 inside, respectively. The auxiliary stationary spring 19 has symmetrically arranged auxiliary stationary contacts 20 inside. When the enameled wire 4 is energized, a magnetic field is generated, causing the armature structure 7 to drive the pusher 6 to swing. Since the left three-armed spring 14 and right three-armed spring 21 are riveted to both ends of the moving piece 12, and the moving piece 12 is installed between the left stationary spring 8 and the right stationary spring 10, the pusher 6 has two slots. When the pusher 6 swings, it can drive the left three-armed spring 14 and right three-armed spring 21 to move in the same direction. Additionally, an auxiliary contact structure is provided, with the auxiliary stationary spring 19 located between the left and right auxiliary moving springs 15 and 17. In the middle of the moving spring 17, two slots on the push plate 6 simultaneously drive the left auxiliary moving spring 15 and the right auxiliary moving spring 17 to move in the same direction. When the left stationary contact 9 inside the left stationary plate 8 closes with the left active contact 13, the right stationary contact 11 inside the right stationary plate 10 will disconnect from the right active contact 22. At this time, the left auxiliary moving contact 16 will disconnect from the auxiliary stationary contact 20, and the right auxiliary moving contact 18 will close with the auxiliary stationary contact 20. When the left stationary contact 9 inside the left stationary plate 8 disconnects from the left active contact 13, the right stationary contact 11 inside the right stationary plate 10 will close with the right active contact 22. At this time, the left auxiliary moving contact 16 will close with the auxiliary stationary contact 20, and the right auxiliary moving contact 18 will disconnect from the auxiliary stationary contact 20. This is a changeover relay with an auxiliary contact structure. By monitoring two sets of main circuits in this way, the synchronization is more reliable, enhancing the safety and reliability of the circuit.

[0035] In order to effectively monitor the two main circuits, the upper surface of the push plate 6 is provided with a movable groove for the left three-bow plate 14 and the right three-bow plate 21 to move, and the bottom of the push plate 6 is provided with a movable groove for the left auxiliary moving spring 15 and the right auxiliary moving spring 17 to move. Through the multiple movable grooves on the outside of the push plate 6, the push plate 6 can effectively drive the left three-bow plate 14, the right three-bow plate 21, the left auxiliary moving spring 15 and the right auxiliary moving spring 17 to move synchronously, thereby effectively monitoring the two main circuits.

[0036] In order to effectively protect the internal components of the relay, a protective shell 1 is fixedly installed on the outside of the base 2. The protective shell 1 can effectively protect the internal components of the relay, thereby effectively extending the service life of the relay and making it easier for users to assemble and use the relay.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
