Abstract
Description
Technical Field
[0001] This utility model relates to the field of power electronics technology, and in particular to an adjustable solid-state relay. Background Technology
[0002] Solid-state relays, as a type of contactless switching element, are widely used in the field of automation control due to their advantages such as fast switching speed, reliable operation, and long lifespan. In practical applications, solid-state relays usually need to be securely installed on equipment cabinets or control panels to ensure the stability of their electrical connections. Currently, the common installation method is to directly fix them to the mounting surface with bolts or screws. However, this tool-dependent tightening method is cumbersome and time-consuming in situations where frequent installation, disassembly, or replacement of relays is required, reducing the efficiency of assembly and maintenance.
[0003] Furthermore, solid-state relays generate a large amount of heat when they are in operation. If this heat cannot be dissipated in time, it will seriously affect their performance and service life. Therefore, an effective heat dissipation structure is essential. Many heat dissipation structures are designed with heat dissipation channels and filters to prevent dust and other impurities from entering the relay. However, after long-term operation, especially in industrial environments, a large amount of dust will gradually be adsorbed and accumulated on the surface of the filter. If it is not cleaned in time, it will block the airflow path, resulting in a significant decrease in heat dissipation efficiency. Most filters in existing technologies are built-in or clip-on fixed. Their disassembly and cleaning process often requires disassembling part of the relay housing, which is very inconvenient and increases the difficulty and time cost of maintenance.
[0004] Therefore, this invention proposes an adjustable solid-state relay to address the shortcomings of existing technologies. Utility Model Content

[0010] Preferably, slide groove one and slide groove two are aligned after the connecting post is inserted into the hollow post to form a connecting channel through which the U-shaped locking block passes.
[0011] Preferably, the U-shaped locking block has two parallel pins that are used to pass through both slide groove one and slide groove two simultaneously in the locked state.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] Example:
[0028] Please refer to Figures 1 to 4 This utility model provides an adjustable solid-state relay, which aims to solve the problems of cumbersome installation and fixing process and difficulty in disassembling and cleaning the heat dissipation mesh of existing solid-state relays.
[0029] like Figure 1 and Figure 2 As shown, the adjustable solid-state relay includes a controller 1 as the main body, a connection mechanism 2 and a heat dissipation mechanism 3 that are assembled and connected to the controller 1. The connection mechanism 2 is used to realize the quick fixed installation of the controller 1, and the heat dissipation mechanism 3 is used to provide heat dissipation for the controller 1 and constitutes part of the housing of the controller 1.
[0030] Please refer to the following carefully. Figure 3 The following is a detailed description of the connecting mechanism 2:
[0031] The connecting mechanism 2 includes a fixed circular plate 201, a hollow column 203, a U-shaped locking block 204, and a connecting column 206. The fixed circular plate 201 has mounting holes for fixing it to the mounting surface, and a first sliding groove 202 is also provided on the fixed circular plate 201. The hollow column 203 is disposed on the fixed circular plate 201, and a circular groove 207 is provided on the inner wall of the hollow column 203. The connecting column 206, which is integrally formed on the surface of the controller 1's housing, has a second sliding groove 205. During installation, the connecting column 206 of the controller 1 is first inserted into the hollow column 203. Inside, it cooperates with the circular groove 207 to achieve initial positioning. At this time, the first slide groove 202 and the second slide groove 205 are aligned to form a connecting channel for the U-shaped locking block 204 to pass through. Then, the U-shaped locking block 204 with two parallel prongs passes through the first slide groove 202 and the second slide groove 205 in sequence. After passing through, its prongs firmly lock the connecting post 206 in the hollow post 203, thereby stably fixing the controller 1 on the fixed circular plate 201. This plug-in-locking cooperation structure ensures the convenience of installation and the reliability of connection.
[0032] Please refer to the following carefully. Figure 4 The heat dissipation mechanism 3 will be described in detail below:
[0033] The heat dissipation mechanism 3 includes a pipe 301, a rotating shaft 303, a rotating plate 302, a filter 304, a first hook and loop fastener 305, and a second hook and loop fastener 306. The pipe 301 forms a heat dissipation channel for air circulation. The rotating shaft 303 is fixed at one end of the pipe 301. The rotating plate 302 is pivotally mounted on the pipe 301 via the rotating shaft 303, and the rotating plate 302 is configured to rotate between a closed position for closing the port and an open position for exposing the filter 304. The filter 304 is located inside the pipe 301. One side of the filter 304 is detachably fixed to the inner wall of the pipe 301 via the first hook and loop fastener 305, and the other side is detachably fixed to the rotating plate 302 via the second hook and loop fastener 306. This detachable connection structure using hook and loop fasteners ensures that the filter 304 can be easily and quickly replaced or cleaned.
[0034] Working principle: The connecting mechanism 2 is used to connect the controller 1 to the wall. By moving the controller 1, the connecting column 206 begins to move with the controller 1. The connecting column 206 is inserted into the hollow column 203 and its corresponding circular groove 207 to initially connect and fix the controller 1. The hollow column 203 is connected to the wall through the fixed circular plate 201. After fixing the connecting column 206, the U-shaped locking block 204 is aligned with the sliding groove 1 202 and inserted. During the movement of the U-shaped locking block 204, the end passes through the inside of the sliding groove 205, thereby further fixing the connecting column 206 and the controller 1.
[0035] The heat dissipation mechanism 3 is equipped with a removable filter 304, which allows the inside of the controller 1 to be cleaned. During cleaning, the rotating plate 302 is rotated by the rotating shaft 303. The filter 304 is fixed in the pipe 301 by Velcro 1 305 and Velcro 2 306, making it removable. The filter 304 can be replaced by Velcro 1 305 and Velcro 2 306, which makes it convenient and quick to clean the dust and dirt on the filter 304 and effectively ensures the cleanliness of the inside of the relay.
