[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. 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). Commonly used in automated control circuits, it is essentially an "automatic switch" that uses a small current to control a large current, playing roles such as automatic adjustment, safety protection, and circuit switching in the circuit.

[0003] In the prior art, if the operator does not insert the relay module according to the correct operating method and direction, but instead inserts it at an angle or deflection, some pins may make contact with the socket first, thus connecting the power supply. This may result in poor contact of the signal pins, causing problems such as signal distortion, attenuation, or interruption during transmission. Utility Model Content

[0023] 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.

[0024] 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.

[0025] Example 1, such as Figures 1-5 As shown, this utility model provides a pluggable modular power relay, including a socket structure 1. The socket structure 1 includes a connector 101. The outer wall of the connector 101 is provided with a plurality of connecting grooves 102. The top of the connector 101 is provided with a slot 104. The inner wall of the slot 104 is provided with a card slot 105. A pressure sensor 106 is fixedly installed on the inner wall of the card slot 105. A warning light 103 is provided on the top of the connector 101. The top of the connector 101 is provided with a body structure 2.

[0026] The main body structure 2 includes a shell 201, a plurality of pins 202 are provided at the bottom of the shell 201, and a connecting structure 3 is provided on the outer wall of the shell 201;

[0027] The connecting structure 3 includes a connecting frame 301. A limiting groove 303 is opened at the bottom of the connecting frame 301. A spring 304 is fixedly installed on the inner wall of the limiting groove 303. A limiting plate 305 is fixedly installed at one end of the spring 304. A push plate 306 and a locking block 307 are fixedly installed on the outer wall of the limiting plate 305. One end of the push plate 306 passes through the connecting frame 301.

[0028] The effect achieved by the entire embodiment 1 is as follows: When in use, the operator inserts the pin 202 into the connecting groove 102. At the same time, the inclined surface of the locking block 307 contacts the inner wall of the slot 104. The locking block 307 is squeezed and moves, the spring 304 is compressed, and then the locking block 307 continues to move. When the locking block 307 moves to the side of the slot 105, the elastic force of the spring 304 pushes the locking block 307 into the slot 105 and into contact with the pressure sensor 106. The pressure sensor 106 alarms, and the warning light 103 starts to alarm. At this time, the pin 202 is completely inserted into the connecting groove 102, which can prevent poor contact.

[0029] Example 2, as Figures 1-5 As shown, the top of the connecting seat 101 is provided with a sealing groove 107, and a sealing ring 108 is fixedly installed on the inner wall of the sealing groove 107.

[0030] Furthermore, a retaining ring 302 is fixedly installed at the bottom of the connecting frame 301, and the retaining ring 302 is slidably connected to the sealing groove 107.

[0031] Furthermore, a storage groove 203 is provided on the inner wall of the housing 201, and a threaded hole 204 is provided through the inner wall of the storage groove 203. A threaded rod 205 is threadedly connected inside the threaded hole 204. A handle 206 is fixedly installed at one end of the threaded rod 205, and a fixing block 207 is fixedly installed at the other end of the threaded rod 205 away from the handle 206.

[0032] Furthermore, a protective structure 4 is provided on the top of the housing 201. The protective structure 4 includes a protective plate 401. An extension plate 402 is fixedly installed on the bottom of the protective plate 401. A fixing groove 403 is provided on the outer wall of the extension plate 402. The fixing block 207 is slidably connected to the fixing groove 403.

[0033] Furthermore, a sliding groove 308 is provided on the inner wall of the limiting groove 303, and a baffle 309 is fixedly installed on one end of the limiting plate 305 near the sliding groove 308 to prevent dust from entering the limiting groove 303 when not inserted.

[0034] Furthermore, the outer wall of the limiting plate 305 fits against the inner wall of the limiting groove 303 to prevent the limiting plate 305 from tilting.

[0035] The effect achieved by the entire embodiment 2 is that, during insertion, the insertion ring 302 enters the sealing groove 107, the inclined surface of the insertion ring 302 contacts the sealing ring 108, the insertion ring 302 applies pressure to the sealing ring 108, causing the sealing ring 108 to compress. When the insertion ring 302 is fully inserted into the sealing groove 107, the elasticity of the sealing ring 108 reduces the gap between the two, improving the sealing performance and protection capability, and preventing the connection from being affected by external dust and moisture.

[0036] Working principle: During use, the operator inserts pin 202 into the connecting groove 102. Simultaneously, the inclined surface of the locking block 307 contacts the inner wall of the slot 104, causing it to move under pressure. The spring 304 is compressed, and the locking block 307 continues to move. When the locking block 307 moves to the side of the slot 105, the elastic force of the spring 304 pushes it into the slot 105 and into contact with the pressure sensor 106. The pressure sensor 106 alarms, and the warning light 103 starts to sound. At this point, pin 202 is fully inserted into the connecting groove 102, preventing poor contact. Simultaneously, the insert ring 302 enters the sealing groove 107, and its inclined surface contacts the sealing ring 108. The insert ring 302 applies pressure to the sealing ring 108, compressing it. When the insert ring 302 is fully inserted into the sealing groove 107, the elastic force of the sealing ring 108 reduces the gap between them, improving sealing and protection, and preventing the connection from being affected by external dust and moisture. During maintenance, the operator rotates the handle 206, which drives the threaded rod 205 to rotate, causing the threaded rod 205 to move along the threaded hole 204, which in turn causes the fixing block 207 to leave the fixing groove 403. At this point, the operator can pull the protective plate 401 to remove the extension plate 402, thus enabling the operator to begin maintenance of the internal components of the housing 201, which improves maintenance efficiency.

[0037] 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.
