Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a waterproof and moisture-proof protective housing for relays. Background Technology

[0002] A relay is a switching device that uses electromagnetic principles to control circuits. Its main function is to control the switching of high-power circuits using low-power electrical signals. A relay consists of a coil, contacts, and other auxiliary structures. Its basic working principle is that when current flows through the coil of the relay, the coil generates a magnetic field. This magnetic field causes the iron core in the relay to displace, thereby causing the contacts to close or open, thus controlling the circuit. When the current stops flowing through the coil, the magnetic field disappears, and the contacts return to their original state.

[0003] Existing relay housings are prone to cracking after mechanical impacts such as vibration or collisions. Especially in outdoor environments, ultraviolet radiation accelerates material aging, reducing the lifespan of the relay housing. Current solutions involve using die-cast aluminum alloy for the main body of the housing and embedding steel reinforcing ribs in key stress areas to improve impact resistance. However, in humid environments, moisture can still penetrate the housing, causing electrochemical corrosion of the solder pads and surface-mount component leads on the internal circuit board, damaging the relay control circuit and reducing the protective effect of the housing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a waterproof and moisture-proof protective housing for relays, aiming to improve the problem in the prior art where moisture can penetrate the inside of the housing, causing damage to the relay control circuit and reducing the protective effect of the housing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4An embodiment of this utility model provides a waterproof and moisture-proof protective shell for a relay, including a connecting shell 1. The inner wall of the connecting shell 1 is provided with a waterproof mechanism 2, which is used to improve the waterproof effect of the protective shell. The left and right sides of the connecting shell 1 are provided with protective mechanisms 3, which are used to improve the impact resistance of the shell.

[0032] The waterproofing mechanism 2 includes a gel plate 201. The bottom of the gel plate 201 is fixedly connected to the inner bottom wall of the connecting shell 1, which effectively improves the heat insulation effect inside the connecting shell 1. A polymer waterproof membrane 202 is fixedly connected to the top wall of the gel plate 201. The polymer waterproof membrane 202 effectively increases the waterproof effect inside the connecting shell 1 and reduces the impact of water vapor on the relay's operation. The top wall of the polymer waterproof membrane 202 has multiple arc-shaped grooves 203, which effectively improves the toughness of the polymer waterproof membrane 202. A polyurethane waterproof coating board 204 is fixedly connected to the top of the polymer waterproof membrane 202. The seamless elastic coating film formed after the board surface is cured effectively improves the waterproof performance.

[0033] Specifically, the waterproof and moisture-proof protective shell for the relay is based on the connecting shell 1. The waterproof mechanism 2 on its inner wall enhances waterproof performance through a multi-layered structure. In the waterproof mechanism 2, the bottom of the gel plate 201 is fixed to the inner bottom wall of the connecting shell 1. Its inherent properties effectively improve the internal heat insulation of the connecting shell 1, laying the foundation for the waterproof structure. The polymer waterproof membrane 202 connected to the top wall of the gel plate 201 serves as the core waterproof component. By tightly adhering to the inner wall of the connecting shell 1, it enhances the internal waterproof capability, prevents moisture from entering, and reduces the corrosive damage caused by moisture to the relay. To mitigate the risk of disrupting normal operation, multiple arc-shaped grooves 203 are created on the top wall of the polymer waterproof membrane 202. By altering the membrane structure, these grooves effectively enhance its toughness, making it less prone to cracking or damage when subjected to external forces or environmental changes. The polyurethane waterproof coating board 204 connected to the top of the polymer waterproof membrane 202 forms a seamless elastic coating film on the board surface after curing. This coating film, with its excellent sealing and elastic deformation capabilities, further enhances the overall waterproof performance of the protective shell. Through layered combination and functional complementarity, the various components ensure the stable operation of the relay in a waterproof and moisture-proof environment.

[0034] Reference Figure 1 , Figure 2 and Figure 4The protective mechanism 3 includes multiple mounting bolts 301, and protective shells 302 are threadedly connected to adjacent sides of the multiple mounting bolts 301, so that the protective shells 302 can be installed and disassembled by rotating the mounting bolts 301, thereby achieving the purpose of flexible assembly and disassembly. The ends of the mounting bolts 301 are fixedly connected to the front and rear sides of the connecting shell 1, respectively. A fixing frame 303 is fixedly connected to the inner wall of the protective shell 302. The carbon fiber column 305 and the high-strength connecting column 304 can be connected through the fixing frame 303. Multiple carbon fiber columns 305 are fixedly connected to the bottom of the inner wall of the fixing frame 303, and multiple high-strength connecting columns 304 are fixedly connected to the front side of the inner wall of the fixing frame 303. Under the fixation of the carbon fiber columns 305 and the high-strength connecting columns 304, the impact resistance is effectively improved. Heat dissipation components 306 are provided on the opposite sides of the two protective shells 302, so that the heat dissipation effect of the connecting shell 1 is improved by the connection of the heat dissipation components 306.

[0035] Specifically, the protective mechanisms 3 on the left and right sides of the connecting shell 1 are installed and disassembled through the cooperation of multiple mounting bolts 301 with the protective shell 302. One end of the mounting bolt 301 is threaded to the protective shell 302, and the other end is fixed to the front and rear sides of the connecting shell 1. By rotating the mounting bolts 301, the protective shell 302 can be easily installed or disassembled, meeting the needs of flexible installation and disassembly. The fixing frame 303 fixed to the inner wall of the protective shell 302 serves as an internal structural support, providing a connection base for the carbon fiber column 305 and the high-strength connecting column 304. The multiple carbon fiber columns 305 fixed to the bottom of the inner wall of the fixing frame 303, with their high strength, provide a connection base for the carbon fiber column 305 and the high-strength connecting column 304. The high strength and high modulus characteristics, together with the multiple high-strength connecting columns 304 fixed on the front side of the inner wall, work together to disperse and absorb the impact force when subjected to external impact, effectively improving the overall impact resistance of the protective shell 302 and the connecting shell 1. In addition, heat dissipation components 306 are provided on the side of the two protective shells 302 that are far apart. These components are connected to the protective shells 302 and the connecting shell 1. Through specific heat dissipation structures and material properties, they accelerate the conduction and dissipation of internal heat, and promptly discharge the heat generated in the connecting shell 1, thereby improving the heat dissipation effect of the connecting shell 1 and ensuring the stable operation of the relay in a suitable temperature environment.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The heat dissipation component 306 includes multiple heat dissipation slots 3061, which are respectively opened on the opposite sides of the two protective shells 302. Heat dissipation fins 3062 are fixedly connected inside the multiple heat dissipation slots 3061. Multiple high-strength connecting pillars 304 and multiple carbon fiber pillars 305 are fixedly connected and form a rectangular grid structure. The protection mechanism 3 also includes multiple rubber rings 307, the inner walls of which are fixedly connected to the middle of the mounting bolts 301.

[0037] Specifically, the opening and closing of the heat dissipation slot 3061 and the fixing of the heat dissipation fins 3062 improve the heat dissipation effect of the outer shell and complete the heat conduction function. Multiple high-strength connecting columns 304 and multiple carbon fiber columns 305 are fixedly connected and form a rectangular grid structure, which improves the impact resistance of the left and right sides of the protection mechanism 3. The connection of the rubber ring 307 reduces the rotational damage of the mounting bolts 301 to the protective shell 302.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The waterproofing mechanism 2 also includes a silicone sealant plate 206, the top of which is fixedly connected to the inner top wall of the connecting shell 1; an observation window 4 is fixedly installed on the front side of the connecting shell 1, and the outer wall of the observation window 4 is designed to be smooth; multiple carbon fiber plates 205 are fixedly connected to the top wall of the polyurethane waterproof coating plate 204, and the multiple carbon fiber plates 205 are arranged symmetrically at equal intervals.

[0039] Specifically, the silicone sealant plate 206 further improves the sealing effect of the outer shell and reduces the intrusion of moisture. The observation window 4 allows observation of the internal circuit board of the relay. The connection of the carbon fiber plate 205 improves the pressure resistance of the top of the polyurethane waterproof coating plate 204.

[0040] Working principle: The gel plate 201 effectively enhances the internal heat insulation effect by utilizing its own properties, reducing condensation caused by temperature changes. The polymer waterproof membrane 202 connected to the top wall of the gel plate 201 is tightly attached to the inner wall of the connecting shell 1. With its own dense structure, it blocks the intrusion of external water vapor, reducing the risk of water vapor entering the interior of the connecting shell 1 and causing corrosion damage to the relay. The multiple arc-shaped grooves 203 opened on the top wall of the polymer waterproof membrane 202 change the structure of the membrane and enhance its toughness, making it less prone to damage when subjected to changes in the external environment or slight pressure, ensuring the continuous effectiveness of the waterproof function. The polyurethane waterproof coating board 204 connected to the top of the polymer waterproof membrane 202 forms a seamless elastic coating film on the surface of the board after curing. This coating film has good sealing and elastic deformation ability, which can further isolate water vapor and improve the adaptability to the external humid climate. The components of the waterproof mechanism 2 are stacked and combined to effectively improve the waterproof performance of the connecting shell 1 and extend the service life of the relay shell.

[0041] Furthermore, the protective shell 302 is fixed to the front and rear sides of the connecting shell 1 by one end of the mounting bolt 301, and the other end is threaded to the protective shell 302. Rotating the mounting bolt 301 allows the protective shell 302 to be installed or removed, meeting the usage requirements in different scenarios. The fixing frame 303 fixed to the inner wall of the protective shell 302 has multiple carbon fiber columns 305 at the bottom of its inner wall connected to multiple high-strength connecting columns 304 on the front side of the inner wall, forming a rectangular grid structure within the fixing frame 303. The carbon fiber columns 305, with their high strength and high modulus characteristics, work in conjunction with the rigid support of the high-strength connecting columns 304. When external impact forces act on the protective shell 302, this structure can effectively disperse and absorb the impact force, improve the impact resistance of the protective shell 302 and the connecting shell 1, and protect the relay shell. At the same time, the heat dissipation component 306, which is set on the side of the two protective shells 302 that are far apart, quickly conducts and dissipates the heat generated inside the connecting shell 1 through a specific heat dissipation structure and materials, accelerates the heat exchange efficiency, ensures that the relay operates in a suitable temperature environment, and avoids the performance being affected by heat accumulation. All components work together to take into account both protection and heat dissipation functions.
