Description

Technical Field

[0001] This utility model relates to the field of power relay technology, and in particular to a power relay with an anti-jitter armature structure. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in an electrical output circuit when a change in the input quantity reaches a specified requirement. Relays have both a control system and a controlled system, and are commonly used in automated control circuits, playing roles such as automatic adjustment, safety protection, and circuit switching. Fifth-generation signal relays have emerged, which are smaller, consume less power, and have higher reliability.

[0003] In existing technologies, traditional power relays are prone to armature jitter due to vibration during operation. On one hand, the relay's operating environment is complex; external vibration sources such as motor operation and mechanical vibration can easily be transmitted to the relay body, causing unnecessary armature vibration. On the other hand, the instantaneous change in electromagnetic force during the relay's opening and closing process can also trigger armature jitter. However, existing relays lack effective vibration damping and limiting measures in their structural design, failing to fundamentally solve the armature jitter problem caused by vibration and shaking. This makes it difficult to meet the high stability and reliability requirements of modern industrial and electronic equipment for power relays, necessitating improvements. Utility Model Content

[0006] The limiting mechanism includes a limiting rod that is slidably connected to the outer shell.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a power relay with an anti-vibration armature structure, including a housing 1 and a relay body 2. A connector 3 is fixedly installed at the lower end of the relay body 2. A housing cover 4 is provided on the inner side of the housing 1. A rubber pad 5 is provided on the inner side of the housing 1. A limiting mechanism 6 is provided inside the housing 1. The limiting mechanism 6 includes a limiting rod 601, which is slidably connected to the housing 1. A clamping plate 602 is fixedly installed at one end of the limiting rod 601. A tension spring is sleeved on the surface of the limiting rod 601. 603, the other end of the limiting rod 601 is fixedly connected to a pull plate 604, the side of the clamping plate 602 is fixedly connected to a slider 605, the inner side of the housing 1 is provided with a sliding groove 606, the number of rubber pads 5 is two sets, the rubber pads 5 are located on both sides inside the housing 1, the side of the rubber pads 5 is in contact with the side of the relay body 2, one end of the tension spring 603 is fixedly connected to the side of the housing 1, the other end of the tension spring 603 is fixedly connected to the side of the clamping plate 602, and the slider 605 is slidably connected to the sliding groove 606.

[0024] In this embodiment, rubber pads 5 are provided on both sides inside the housing 1, and the sides of the rubber pads 5 are in contact with the sides of the relay body 2. The good elasticity and damping characteristics of the rubber pads 5 can effectively absorb and buffer the vibration generated by the relay body 2 during operation, reduce armature jitter caused by vibration, and at the same time reduce the impact of external vibration on the relay body 2, thereby improving the stability of the power relay operation. Through the provided limiting mechanism 6, when the pull plate 604 is pulled to move the limiting rod 601 and the clamping plate 602, the slider 605 slides in the slide groove 606 to ensure the smoothness of the movement. After the pull plate 604 is released, the tension spring 603 pulls the clamping plate 602 to reset. The clamping plate 602 can limit the relay body 2, prevent the relay body 2 from shaking inside the housing 1, further reduce armature jitter caused by shaking, and ensure the reliable operation of the power relay.

[0025] Example 2: As Figures 1-4 As shown, a protrusion 12 is fixedly connected to the side of the shell cover 4, a groove 13 is provided on the side of the shell 1, a slot 14 is provided on the side of the protrusion 12, a locking block 15 is slidably connected inside the shell 1, and an anti-slip strip 16 is provided on the surface of the shell cover 4. The protrusion 12 and the groove 13 are slidably connected, and the locking block 15 and the slot 14 are engaged.

[0026] In this embodiment, the cover 4 is fixed to the outer shell 1 by means of a sliding connection between the protrusion 12 and the groove 13 and a locking block 15 and the slot 14. When it is necessary to remove the cover 4 to inspect the relay body 2 inside the outer shell 1, first pull the locking block 15 out of the slot 14 on the side of the protrusion 12, then place your finger on the surface of the anti-slip strip 16 and pull out the cover 4 by means of the sliding principle, so as to facilitate the disassembly of the cover 4. The anti-slip strip 16 on the cover 4 facilitates the opening and closing of the cover 4.

[0027] The working principle of this embodiment is as follows: When the power relay is working, the connector 3 at the lower end of the relay body 2 makes the corresponding connection. During the operation, the rubber pads 5 on both sides inside the outer casing 1 play a role. Utilizing the good elasticity and damping characteristics of the rubber pads 5, the vibration generated by the relay body 2 during operation can be effectively absorbed and buffered, reducing armature jitter caused by vibration. Through the set limiting mechanism 6, when the pull plate 604 is pulled to move the limiting rod 601 and the clamping plate 602, the slider 605 slides in the slide groove 606 to ensure the smoothness of the movement. After the pull plate 604 is released, the tension spring 603 pulls the clamping plate 602 to reset. The clamping plate 602 can limit the relay body 2. To prevent the relay body 2 from shaking inside the housing 1, further reduce armature jitter caused by shaking, and ensure the reliable operation of the power relay, when it is necessary to inspect the relay body 2 inside the housing 1, the housing cover 4 is disassembled. First, the sliding connecting block 15 inside the housing 1 is pulled out from the slot 14 opened in the protrusion 12 on the side of the housing cover 4, releasing the locking and fixing of the block 15 to the protrusion 12. Then, the fingers are placed on the anti-slip strip 16 on the surface of the housing cover 4, and the housing cover 4 is pulled out by using the sliding connection between the protrusion 12 and the protrusion 13 on the side of the housing 1. This makes it convenient to inspect and maintain the relay body 2. The anti-slip strip 16 on the housing cover 4 provides a convenient point of force for opening and closing the housing cover 4.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
