Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to a waterproof controller. Background Art

[0002] With the widespread use of electronic devices in various environments, especially those used outdoors, underwater, or in other humid environments, the requirements for electronic device protection are becoming increasingly stringent. As a key component of these devices, waterproof controllers must not only ensure normal operation of the equipment but also effectively prevent moisture from entering the internal parts to avoid short circuits or other electrical failures.

[0003] Common waterproof controllers on the market today primarily consist of a housing, a circuit board, power cables, and signal cables. The circuit board is housed within the housing, while the power cables and signal cables are electrically connected to the circuit board. To improve waterproof performance, existing waterproof controllers are typically encapsulated with sealing materials, such as rubber seals or waterproof tape, to prevent moisture intrusion.

[0004] However, this traditional waterproofing method has some shortcomings: First, it is difficult to ensure long-term stable and reliable waterproofing effects by relying solely on external sealing materials, especially when used for a long time or in harsh environments, they are prone to aging and wear. These factors will cause the sealing material to lose elasticity or deform, thereby reducing its waterproof performance; second, if the sealing material is not handled properly during the installation process, such as not being sufficiently tightened or not fully covering the required area, it will also cause moisture to penetrate; in addition, in order to achieve a higher waterproof level, more expensive materials and technologies are often required, which will undoubtedly increase product costs.

[0005] In view of the above problems, it is necessary to develop a new waterproof controller to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Embodiment 1: As shown in the figure, a waterproof controller includes a box body 1, a circuit board 2, a power line 3 and a signal line 4. The circuit board 2 is arranged in the box body 1, and the power line 3 and the signal line 4 are electrically connected to the circuit board 2 respectively. It also includes a partition 5 arranged in the box body 1, and the partition 5 divides the space in the box body 1 into a glue potting cavity 6 and an installation cavity 7, and a first sealing ring 8 is arranged between the partition 5 and the box body 1, and the glue potting cavity 6 is filled with sealant 9. The power line 3 and the signal line 4 pass through the glue potting cavity 6 and extend into the installation cavity 7 to be electrically connected to the circuit board 2, and a first sealing member 10 is arranged between the power line 3 and the partition 5, and a second sealing member 11 is arranged between the signal line 4 and the partition 5.

[0029] Embodiment 2: As shown in the figure, the difference from embodiment 1 is that the outer wall of the partition 5 is provided with circumferentially distributed embedding grooves 12, the first sealing ring 8 is embedded in the embedding grooves 12, and the first sealing ring 8 is in close contact with the inner wall of the box body 1.

[0030] The outer wall of the partition 5 is provided with circumferentially distributed embedding grooves 12, which provide a space for the first sealing ring 8 to be embedded. The first sealing ring 8 is embedded in the embedding grooves 12 and is in close contact with the inner wall of the box body 1, forming an effective sealing barrier. This nested structure can effectively fix the position of the first sealing ring 8 to prevent it from loosening or shifting during use, ensuring the durability of the sealing effect. Even if a small amount of moisture penetrates into the embedding grooves 12, it will be firmly blocked by the first sealing ring 8 and cannot enter the installation cavity 7, thereby protecting the circuit board 2.

[0031] In this embodiment, a first through hole 13 and a second through hole 14 are provided on the partition plate 5 . The first sealing member 10 is disposed in the first through hole 13 , and the second sealing member 11 is disposed in the second through hole 14 .

[0032] In the above structure, this design structure can not only improve the waterproof performance, but also ensure the connection stability of the cable. The first seal 10 and the second seal 11 can effectively fix the position of the cable to prevent it from loosening or falling off during use, ensuring the normal connection between the power line 3 and the signal line 4 and the circuit board 2, thereby improving the overall stability and reliability of the controller.

[0033] Specifically, the first through hole 13 and the second through hole 14 provided on the partition 5 correspond to the power line 3 and the signal line 4, respectively, ensuring that the cables can smoothly pass through the partition 5 and connect to the circuit board 2 in the installation cavity 7. In order to prevent moisture from entering the installation cavity 7 along the cable, the design also clamps a first seal 10 and a second seal 11 in the first through hole 13 and the second through hole 14, respectively. The first seal 10 and the second seal 11 can be made of elastic materials with good waterproof properties such as rubber and silicone, and are designed according to the diameter of the cable to ensure that they can be tightly clamped in the through hole to prevent moisture penetration. This clamping structure can effectively prevent gaps between the cable and the partition 5, effectively prevent the intrusion of moisture, and improve the controller's resistance to the external environment.

[0034] In this embodiment, the first seal 10 has a first through-hole 15 for the power cord 3 to pass through, and a first contact ring 16 that is in close contact with the power cord 3 is provided at the bottom of the first through-hole 15, and a circumferentially distributed first card groove 17 is provided on the outer side of the first seal 10, and the first card groove 17 is clamped in the first through-hole 13. The upper end of the first seal 10 is also provided with a first abutment ring 18 for abutting against the upper end of the partition 5.

[0035] In the above structure, the first sealing member 10 has a first through-hole 15 for the power cord 3 to pass through, ensuring that the power cord 3 can smoothly pass through the sealing member and be connected to the circuit board 2. In order to prevent moisture from entering the mounting cavity 7 through the through-hole, a first contact ring 16 that is in close contact with the power cord 3 is provided at the bottom of the first through-hole 15. The close fit of the contact ring can effectively prevent moisture from entering the mounting cavity 7 along the power cord 3, thereby improving the sealing effect.

[0036] To further secure the position of the first seal 10 and prevent it from loosening, the design provides circumferentially distributed first retaining grooves 17 on the outside of the first seal 10. The first retaining grooves 17 are positioned within the first through-hole 13, effectively securing the first seal 10 and preventing it from loosening or shifting during use. Furthermore, the upper end of the first seal 10 is provided with a resting ring for abutting against the upper end of the partition 5, effectively preventing the first seal 10 from shifting or falling off during use, further enhancing sealing reliability.

[0037] This design structure not only improves the reliability of the seal, but also facilitates production and assembly. The clip-on structure can make the first seal 10 more firmly fixed in the through hole, avoiding the disadvantages of the traditional sealant 9 that is easy to fall off or age. At the same time, the design of the first contact ring 16 can effectively prevent the power cord 3 from loosening or falling off during use, ensuring the normal connection between the power cord 3 and the circuit board 2, and improving the overall stability and reliability of the controller.

[0038] In this embodiment, the second sealing member 11 has a second through-hole 19 for the power cord 3 to pass through, and a second contact ring 20 that is in close contact with the power cord 3 is provided at the bottom of the second through-hole 19, and a circumferentially distributed second card groove 21 is provided on the outer side of the second sealing member 11, and the second card groove 21 is clamped in the second through-hole 14. The upper end of the second sealing member 11 is also provided with a second abutment ring 22 for abutting against the upper end of the partition 5.

[0039] In the above structure, the second sealing member 11 has a second through-hole 19 for the signal line 4 to pass through, ensuring that the signal line 4 can smoothly pass through the sealing member and be connected to the circuit board 2. In order to prevent moisture from entering the mounting cavity 7 through the through-hole, a second contact ring 20 that is in close contact with the signal line 4 is provided at the bottom of the second through-hole 19. The close fit of the contact ring can effectively prevent moisture from entering the mounting cavity 7 along the signal line 4, thereby improving the sealing effect.

[0040] To further secure the position of the second seal 11 and prevent it from loosening, the design provides circumferentially distributed second retaining grooves 21 on the outside of the second seal 11. The second retaining grooves 21 are positioned within the second through-hole 14, effectively securing the second seal 11 and preventing it from loosening or shifting during use. Furthermore, a second abutment ring 22 is provided at the upper end of the second seal 11 for abutting against the upper end of the partition 5, effectively preventing the second seal 11 from shifting or falling off during use and further enhancing sealing reliability.

[0041] Embodiment 3: As shown in the figure, different from Embodiment 2, the box body 1 includes an end cover 23 and a shell 24, the end cover 23 is sealed to the upper end of the shell 24, and the lower end of the end cover 23 is provided with a retaining ring 25 for extending into the glue pouring cavity 6, and the retaining ring 25 is arranged close to the outer edge of the end cover 23.

[0042] In the above structure, the end cap 23 is sealed to the upper end of the housing 24, forming a sealed cavity to facilitate the glue pouring operation. The retaining ring 25 is arranged at the lower end of the end cap 23, close to the outer edge of the end cap 23, and extends into the glue pouring cavity 6. The design of the retaining ring 25 can effectively limit the filling range of the sealant 9, preventing the sealant 9 from overflowing during the glue pouring process, and ensuring that the sealant 9 can evenly fill the glue pouring cavity 6 to avoid gaps, thereby improving the sealing effect. At the same time, the retaining ring 25 can also effectively prevent the sealant 9 from shrinking during the curing process, which would lead to a decrease in the sealing effect. After the sealant 9 is cured, the retaining ring 25 can effectively prevent the sealant 9 from shrinking, ensuring close contact between the sealant 9 and the box body 1 and the partition 5, thereby improving the waterproof performance.

[0043] In this embodiment, the end cover 23 is respectively clamped with a first clamping sleeve 26 and a second clamping sleeve 27, the first clamping sleeve 26 and the second clamping sleeve 27 are spaced apart, and the first clamping sleeve 26 is provided with a first threading hole 28 for the power cord 3 to pass through, and the second clamping sleeve 27 is provided with a second threading hole 29 for the power cord 3 to pass through.

[0044] The waterproof controller is provided with a first ferrule 26 and a second ferrule 27 on the end cover 23, and wire holes are respectively provided on the ferrules, which effectively solves the sealing problem when the power line 3 and the signal line 4 pass through the end cover 23, improves the waterproof performance of the controller, and simplifies the cable wiring process.

[0045] Specifically, the first ferrule 26 and the second ferrule 27 are spaced apart on the end cap 23 to facilitate the power cord 3 and the signal cord 4 to pass through the end cap 23, respectively. The first ferrule 26 is provided with a first threading hole 28 for the power cord 3 to pass through, and the second ferrule 27 is provided with a second threading hole 29 for the signal cord 4 to pass through. The design of the threading holes ensures that the cables can smoothly pass through the end cap 23 and connect with the circuit board 2 in the mounting cavity 7. The design of the ferrule can effectively fix the position of the cable, preventing the cable from loosening or falling off during use, thereby improving the overall stability and reliability of the controller. At the same time, the structure of the ferrule can also effectively prevent moisture from entering the controller along the cable, thereby improving the waterproof performance of the controller.

[0046] In this embodiment, two guide posts 30 are fixed on the partition 5 at intervals, and a sleeve 31 corresponding to the guide post 30 is provided at the lower end of the end cover 23. The sleeve 31 cooperates with the guide post 30 to achieve positioning of the end cover 23 and the shell 24.

[0047] In the above structure, two guide posts 30 are fixed at intervals on the partition 5, providing precise guidance for the positioning of the end cap 23. A sleeve 31 corresponding to the guide posts 30 is provided at the lower end of the end cap 23. The cooperation between the sleeve 31 and the guide post 30 ensures that the end cap 23 always maintains the correct orientation and position during installation. This positioning method not only improves assembly accuracy but also effectively reduces errors during the assembly process, avoiding poor sealing caused by improper installation. In addition, the cooperation between the guide post 30 and the sleeve 31 effectively prevents the end cap 23 from shaking or shifting during installation, ensuring the stability of the sealing effect.

[0048] In this embodiment, a glue injection hole 32 communicating with the glue injection cavity 6 is further provided on the end cover 23 .

[0049] In the above structure, the glue injection hole 32 is connected to the glue injection cavity 6, making it convenient for the operator to inject the sealant 9 into the glue injection cavity 6. During the glue injection process, the operator only needs to inject the sealant 9 into the glue injection cavity 6 through the glue injection hole 32 to complete the filling of the sealant 9. This design simplifies the glue injection operation, eliminating the need for complex operation steps, reducing operational difficulty, and improving production efficiency. Furthermore, the design of the glue injection hole 32 also effectively prevents the sealant 9 from overflowing during the glue injection process. When the sealant 9 is injected into the glue injection cavity 6, the glue injection status can be observed through the glue injection hole 32, ensuring that the sealant 9 fills the glue injection cavity 6 evenly, avoiding gaps, and improving the sealing effect.

[0050] In this embodiment, the sealant 9 is at least one of epoxy resin, polyurethane, silicone, acrylic acid, polysulfide rubber, silicone and polyester resin.

[0051] The waterproof controller uses at least one of epoxy resin, polyurethane, silicone, acrylic, polysulfide rubber, silicone and polyester resin as sealant 9, which can effectively prevent moisture penetration and improve waterproof performance. The appropriate sealant 9 can be selected according to actual needs to meet different application scenarios.

[0052] Materials such as epoxy resin, polyurethane, silicone, acrylic, polysulfide rubber, silicone, and polyester resin all have excellent waterproof properties and can form a solid sealing layer after curing, effectively blocking the penetration of water. These materials are also resistant to various chemicals and temperature changes, and can maintain good waterproof effects in various environments, extending the service life of the controller. At the same time, different sealant 9 materials also have different characteristics. For example, epoxy resin has high strength and corrosion resistance, polyurethane has good elasticity and wear resistance, silicone has good high temperature resistance and low temperature resistance, acrylic has good weather resistance and UV resistance, polysulfide rubber has good oil resistance and chemical corrosion resistance, silicone has good adhesion and waterproof properties, and polyester resin has good water resistance and oil resistance. Therefore, according to the actual application scenario, you can choose the appropriate sealant 9 material to ensure the waterproof performance and service life of the controller.

[0053] In this embodiment, a microswitch 33 electrically connected to the circuit board 2 is further provided at the bottom of the box body 1, with a second sealing ring 34 disposed between the microswitch 33 and the box body 1. This design effectively improves the controller's waterproof performance, preventing short circuits or other faults caused by moisture intrusion, thereby increasing the controller's stability and service life. Furthermore, the provision of the second sealing ring 34 facilitates the replacement and maintenance of the microswitch 33. If the microswitch 33 malfunctions, the microswitch 33 can be easily replaced by simply removing the second sealing ring 34. This is a quick and convenient method, eliminating the need to disassemble the entire controller and reducing maintenance costs.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
