Description

Technical Field

[0001] This utility model relates to the field of relay technology, and more specifically, to a magnetic latching relay with auxiliary contacts. 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 change in the input quantity (excitation quantity) reaches a specified requirement. When using a relay, a magnetic latching relay with auxiliary contacts is required.

[0003] Traditional relays cannot effectively monitor the on / off status of the main circuit, thus reducing the overall reliability of the relay and the safety of the main circuit. At the same time, traditional relays have a short creepage distance, which reduces the overall electrical reliability of the relay.

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

[0005] The purpose of this utility model is to provide a magnetic latching relay with auxiliary contacts, including a housing, and further comprising:

[0006] A base is disposed inside the outer shell. A frame is fixedly installed on the upper surface of the base. Enamelled wire is provided on the outside of the frame. Two non-right-angle yokes are provided inside the frame.

[0007] An armature structure is disposed inside the base;

[0008] The left stationary plate, the right stationary plate, and the moving plate are all installed inside the base. The left stationary plate is riveted with a left stationary contact, and the right stationary plate is riveted with a right stationary contact. The outer walls of the moving plate are riveted with left three-arch plates and right three-arch plates respectively. The left three-arch plates are riveted with a left moving contact, and the right three-arch plates are riveted with a right moving contact.

[0009] A drive component is located inside the base;

[0010] An auxiliary contact assembly is disposed inside the base.

[0011] As a further improvement to this technical solution, the pushing component includes a pusher plate disposed inside the base, and the upper surface of the pusher plate is provided with movable grooves for the armature structure, the left three bow plates and the right three bow plates to move.

[0012] 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 auxiliary moving spring is riveted with a left auxiliary contact, the right auxiliary moving spring is riveted with a right auxiliary contact, and the auxiliary stationary spring is symmetrically riveted with stationary auxiliary contacts.

[0013] As a further improvement to this technical solution, the bottom of the push plate is provided with movable grooves for the left auxiliary moving spring and the right auxiliary moving spring to move.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this magnetic latching relay with auxiliary contacts, a push component and an auxiliary contact component are configured. The push component, during operation, moves the left three-pronged spring, right three-pronged spring, left auxiliary moving spring, and right auxiliary moving spring. This allows the auxiliary contact component to monitor the on / off status of the main circuit, effectively improving the overall reliability of the relay and the safety of the main circuit. Furthermore, the auxiliary contact component has two different monitoring states: when the left moving contact, right moving contact, left auxiliary contact, and right auxiliary contact are in the same state, the left moving contact or right moving contact... When the stationary contact or the right stationary contact is disconnected, the left auxiliary contact or the right auxiliary contact will also be disconnected. When the states of the left and right auxiliary contacts are opposite to those of the left and right moving contacts, the left or right moving contact is disconnected from the left or right stationary contact, and the left or right auxiliary contact will be engaged with the stationary auxiliary contact. These two different states can effectively increase the diversity of the overall internal circuit design of the relay, increase the overall reliability of the relay, and enhance the safety and reliability of the main circuit. At the same time, the use of plug-in non-right-angle yoke can effectively increase the creepage distance and increase the overall electrical performance reliability of the relay.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 - Figure 4 As shown, this embodiment provides a magnetic latching relay with auxiliary contacts, including a housing 1, and further including:

[0024] The base 2 is located inside the outer shell 1. A frame 3 is fixedly installed on the upper surface of the base 2. The frame 3 is provided with an enameled wire 4 on the outside and two non-right-angle yokes 5 inside the frame 3.

[0025] An armature structure 16 is located inside the base 2;

[0026] Left stationary plate 7, right stationary plate 8 and moving plate 6 are all installed inside the base 2. Left stationary plate 7 has a left stationary contact 11 riveted inside, and right stationary plate 8 has a right stationary contact 13 riveted inside. Left three-arch plate 9 and right three-arch plate 10 are riveted to the outer walls of moving plate 6 respectively. Left three-arch plate 9 has a left moving contact 12 riveted inside, and right three-arch plate 10 has a right moving contact 14 riveted inside.

[0027] The drive component is located inside base 2;

[0028] The auxiliary contact assembly is located inside the base 2.

[0029] The above working principle is as follows: By setting the push component, the relay as a whole can move the left three-pronged contact 9, the right three-pronged contact 10, the left auxiliary moving spring 17, and the right auxiliary moving spring 18 during operation. This allows the auxiliary contact assembly to monitor the continuity of the main circuit of the relay, effectively improving the overall reliability of the relay and the safety of the main circuit. Furthermore, the auxiliary contact assembly has two different monitoring states. When the left moving contact 12, the right moving contact 14, the left auxiliary contact 19, and the right auxiliary contact 20 are in the same state, the left moving contact 12 or the right moving contact 14 is disconnected from the left stationary contact 11 or the right stationary contact 13, and the left auxiliary contact... Point 19 or right auxiliary contact 20 will also disconnect stationary auxiliary contact 22. When the states of left auxiliary contact 19 and right auxiliary contact 20 are opposite to those of left moving contact 12 and right moving contact 14, left moving contact 12 or right moving contact 14 will disconnect from left stationary contact 11 or right stationary contact 13, and left auxiliary contact 19 or right auxiliary contact 20 will engage with stationary auxiliary contact 22. These two different states can effectively increase the diversity of the overall internal circuit design of the relay, increase the overall reliability of the relay, and enhance the safety and reliability of the main circuit. At the same time, the use of plug-in non-right-angle yoke 5 can effectively increase the creepage distance and increase the overall electrical performance reliability of the relay.

[0030] In order to enable the relay to operate normally, the driving component includes a push plate 15 disposed inside the base 2. The upper surface of the push plate 15 is provided with movable slots for the armature structure 16, the left three-piece plate 9, and the right three-piece plate 10 to move. When the enameled wire 4 is energized, the generated magnetic field will cause the armature structure 16 to drive the push plate 15 to swing synchronously. At this time, the push plate 15 can effectively push the left three-piece plate 9 and the right three-piece plate 10 to move synchronously, thereby enabling the relay to operate normally.

[0031] Considering the need to monitor the continuity of the main circuit when using the relay, the auxiliary contact assembly includes a left auxiliary moving spring 17, a right auxiliary moving spring 18, and an auxiliary stationary spring 21, each located inside the base 2. The left auxiliary moving spring 17 is riveted to a left auxiliary contact 19, the right auxiliary moving spring 18 is riveted to a right auxiliary contact 20, and the auxiliary stationary spring 21 is symmetrically riveted to a stationary auxiliary contact 22. During the movement of the push plate 15, the left and right auxiliary moving springs 17 and 18 will move synchronously. At this time, the left and right auxiliary moving springs 17 and 18 will drive the left and right auxiliary contacts 19 and 20 to move synchronously. Thus, the continuity of the main circuit of the relay can be monitored by observing the open and closed states between the left and right auxiliary contacts 19 and 20 and the stationary auxiliary contact 22, effectively improving the overall reliability of the relay and the safety of the main circuit.

[0032] In order to enable the push plate 15 to effectively drive the left auxiliary moving spring 17 and the right auxiliary moving spring 18 to move synchronously, the bottom of the push plate 15 is provided with movable slots for the left auxiliary moving spring 17 and the right auxiliary moving spring 18 to move. Since the bottom of the push plate 15 is provided with movable slots for the left auxiliary moving spring 17 and the right auxiliary moving spring 18 to move synchronously, the push plate 15 will drive the left auxiliary moving spring 17 and the right auxiliary moving spring 18 to move synchronously during the movement. This enables the auxiliary contact assembly to effectively monitor the on / off status of the main circuit of the relay, further improving the overall safety factor of the relay.

[0033] 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. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
