Description

Technical Field

[0001] This application relates to the field of sensor protection device technology, and in particular to a fan-shaped angle sensor housing. Background Technology

[0002] Sensors are increasingly used in industrial, agricultural, and marine environments. However, in high humidity and misty environments, the signal transmission and lifespan of sensors are severely affected. Therefore, sensors are generally equipped with protective devices. With the improvement of sensor accuracy and the diversification of application environments, higher requirements are placed on the sealing and signal enhancement functions of protective devices.

[0003] Currently, most common sensor protection devices on the market are simple sealing structures. Although they can prevent moisture from directly entering, they are not effective at blocking water mist laterally, leading to signal attenuation and corrosion of internal components. Therefore, an improvement has been made to the housing of a fan-shaped angle sensor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a fan-shaped angle sensor housing, which overcomes the deficiencies of existing technologies and aims to solve the problem that most common sensor protection devices on the market are simple sealing structures. Although they can prevent direct water intrusion, they are not effective in blocking water mist laterally, leading to signal attenuation and corrosion of internal components.

[0005] To achieve the above objectives, this application provides the following technical solution: a fan-shaped angle sensor cover, comprising a sensor body, wherein a fan-shaped angle cover is fitted onto the outer wall of the sensor body near its lower end, the fan-shaped angle cover is designed in a trumpet shape, and the upper end of the fan-shaped angle cover covers the sensor body below it, and a sealing ring is fixedly connected inside the fan-shaped angle cover, the sealing ring being located between the fan-shaped angle cover and the sensor body.

[0006] By adopting the above technical solution, a fan-shaped angled cover is fitted onto the outer wall of the sensor body, and a sealing ring fixed inside is sandwiched between the sensor body and the fan-shaped angled cover, forming a structural support and sealing barrier. The horn-shaped fan-shaped angled cover forms a lateral barrier through its inclined side. When water mist drifts laterally, the side of the fan-shaped angled cover will preferentially block the water mist, preventing it from directly contacting the sensitive area of ​​the sensor body. This solves the problem of insufficient lateral water mist blocking by traditional sealing structures, which helps to reduce the signal attenuation of the sensor body. The sealing ring, as the sealing medium between the sensor body and the fan-shaped angled cover, prevents moisture from entering from the connection gap, further improving the sealing and waterproof performance.

[0007] As a preferred technical solution of this application, the outer wall of the sensor body is provided with an external thread near the lower end, and the inner wall of the upper opening of the fan-shaped angle cover is provided with an internal thread, and the internal thread and the external thread are engaged.

[0008] By adopting the above technical solution, the fan-shaped angle outer cover is threaded onto the outer wall of the sensor body through the threaded engagement between the internal and external threads. This facilitates disassembly and assembly, and makes maintenance easier. Furthermore, the threaded connection allows for precise control of the assembly gap between the fan-shaped angle outer cover and the sensor body, ensuring that the sealing ring is evenly compressed and improving sealing reliability. As a preferred technical solution of this application, the sealing ring has an O-shaped structure design and is made of nitrile rubber material.

[0009] By adopting the above technical solution, the O-ring structure design fills the gap through elastic deformation, and the sealing effect is better than that of a flat seal. Nitrile rubber has excellent oil resistance and moisture resistance, and stable elasticity, making it suitable for maintaining sealing performance in long-term humid environments.

[0010] As a preferred embodiment of this application, the inner wall of the sealing ring is fitted with the outer wall of the sensor body, and the outer wall of the sealing ring is fitted with the inner wall of the fan-shaped angle cover.

[0011] By adopting the above technical solution, the sealing ring can fill the gap between the fan-shaped angle outer cover and the sensor body, ensuring sealing performance.

[0012] As a preferred technical solution of this application, the fan-shaped angle cover is made of APS material, and the outer surface of the fan-shaped angle cover is provided with a nano-hydrophobic film.

[0013] By adopting the above technical solution, the fan-shaped angle cover made of APS material has strong corrosion resistance, is not easily corroded, has a long service life, and the nano hydrophobic film can reduce the adhesion of water droplets, allowing the water droplets condensed by water mist to slide off quickly, reducing water accumulation on the surface of the fan-shaped angle cover and enhancing drainage efficiency.

[0014] As a preferred technical solution of this application, the outer wall of the sensor body is provided with a water-guiding thread above the fan-shaped angle outer cover.

[0015] By adopting the above technical solution, when water droplets adhere, the water-guiding threads will guide the water droplets to flow downwards along the spiral path, preventing water droplets from lingering on the surface of the sensor body.

[0016] As a preferred technical solution of this application, a wire is fixedly connected to the upper end of the sensor body, and a connector is fixedly connected to the other end of the wire.

[0017] By adopting the above technical solution, the wires and connectors at the upper end of the sensor body serve as signal output channels, enabling the sensor body to be electrically connected to an external power source.

[0018] In summary, the beneficial effects of this application are as follows: In this application, a fan-shaped angled cover is fitted onto the outer wall of the sensor body, and a sealing ring fixed inside is sandwiched between the sensor body and the fan-shaped angled cover, forming a structural support and sealing barrier. The horn-shaped fan-shaped angled cover forms a lateral barrier through its inclined side. When water mist drifts laterally, the side of the fan-shaped angled cover will preferentially block the water mist, preventing it from directly contacting the sensitive area of ​​the sensor body. This solves the problem of insufficient lateral water mist blocking in traditional sealing structures and helps reduce the signal attenuation of the sensor body. The sealing ring, as the sealing medium between the sensor body and the fan-shaped angled cover, prevents moisture from entering from the connection gap, further improving the sealing and waterproof performance.

[0021] To make the technical means, creative features, objectives and effects of this application easy to understand, the following describes this application in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 4As shown in the figure, this embodiment provides a fan-shaped angle sensor cover, including a sensor body 1. A fan-shaped angle cover 2 is fitted on the outer wall of the sensor body 1 near the lower end. The fan-shaped angle cover 2 has a trumpet-shaped design, and the upper end of the fan-shaped angle cover 2 covers the sensor body 1 below it. A sealing ring 3 is fixedly connected inside the fan-shaped angle cover 2. The sealing ring 3 is located between the fan-shaped angle cover 2 and the sensor body 1. In use, the fan-shaped angle cover 2 is fitted on the outer wall of the sensor body 1, and the sealing ring 3 fixed inside is sandwiched between the sensor body 1 and the fan-shaped angle cover 2, forming a structural support and sealing barrier. The trumpet-shaped structure of the fan-shaped angle cover 2 forms a lateral barrier through its inclined side. When water mist is dispersed laterally, the side of the fan-shaped angle cover 2 will preferentially block the water mist, preventing it from directly contacting the sensitive area of ​​the sensor body 1. This solves the problem of insufficient lateral water mist blocking by traditional sealing structures and helps to reduce the signal attenuation of the sensor body 1. The sealing ring 3, as the sealing medium between the sensor body 1 and the fan-shaped angle cover 2, prevents moisture from entering from the connection gap, further improving the sealing and waterproof performance.

[0023] In this embodiment, as Figure 1 and 2 As shown, the outer wall of the sensor body 1 has an external thread 4 near its lower end, and the inner wall of the upper opening of the fan-shaped angle cover 2 has an internal thread 5. The internal thread 5 and the external thread 4 mesh with each other. In use, the fan-shaped angle cover 2 is threaded onto the outer wall of the sensor body 1 through the threaded engagement between the internal thread 5 and the external thread 4, which facilitates disassembly and maintenance. Furthermore, the threaded connection allows for precise control of the assembly gap between the fan-shaped angle cover 2 and the sensor body 1, ensuring that the sealing ring 3 is evenly compressed and improving sealing reliability. In this embodiment, as Figure 2 As shown, the sealing ring 3 has an O-ring structure design and is made of nitrile rubber. When in use, the O-ring structure design of the sealing ring 3 fills the gap through elastic deformation, and the sealing effect is better than that of a flat seal. Nitrile rubber has excellent oil resistance and moisture resistance, and stable elasticity, making it suitable for maintaining sealing performance in long-term humid environments.

[0024] In this embodiment, as Figure 3 and 4 As shown, the inner wall of the sealing ring 3 is in contact with the outer wall of the sensor body 1, and the outer wall of the sealing ring 3 is in contact with the inner wall of the fan-shaped angle outer cover 2. In use, the sealing ring 3 can fill the gap between the fan-shaped angle outer cover 2 and the sensor body 1 to ensure sealing.

[0025] In this embodiment, as Figure 1As shown, the fan-shaped angle outer cover 2 is made of APS material, and the outer surface of the fan-shaped angle outer cover 2 is provided with a nano hydrophobic film. When in use, the fan-shaped angle outer cover 2 made of APS material has strong corrosion resistance, is not easily corroded, and has a long service life. The nano hydrophobic film can reduce the adhesion of water droplets, allowing the water droplets condensed by water mist to slide off quickly, reducing water accumulation on the surface of the fan-shaped angle outer cover 2 and enhancing drainage efficiency.

[0026] In this embodiment, as Figure 2 As shown, the outer wall of the sensor body 1 is provided with a water guiding thread 6 above the fan-shaped angle outer cover 2. When water droplets adhere to it during use, the water guiding thread 6 will guide the water droplets to flow downward along the spiral path, so as to prevent the water droplets from lingering on the surface of the sensor body 1.

[0027] In this embodiment, as Figure 1 As shown, a wire 7 is fixedly connected to the upper end of the sensor body 1, and a connector 8 is fixedly connected to the other end of the wire 7. In use, the wire 7 and the connector 8 at the upper end of the sensor body 1 serve as a signal output channel, enabling the sensor body 1 to be electrically connected to an external power source.

[0028] The working principle of this application is as follows: When using the sector-shaped angle sensor cover of this application, the operator first places the sector-shaped angle cover 2 onto the sensor body 1, then rotates the sector-shaped angle cover 2. Utilizing the threaded engagement between the internal thread 5 and the external thread 4, the sector-shaped angle cover 2 is threaded onto the outer wall of the sensor body 1. During this process, the sealing ring 3 is evenly compressed to fill the connection gap between the sector-shaped angle cover 2 and the sensor body 1. This completes the installation of the sector-shaped angle cover 2. In subsequent use, the trumpet-shaped sector-shaped angle cover 2... The inclined side forms a lateral barrier. When water mist drifts laterally, the side of the fan-shaped angled outer cover 2 will preferentially block the water mist. Moreover, the nano-hydrophobic film on its outer surface can reduce the adhesion of water droplets, causing the water droplets condensed from the water mist to slide off quickly, reducing water accumulation on the surface of the fan-shaped angled outer cover 2 and preventing it from directly contacting the sensitive area of ​​the sensor body 1. This solves the problem of insufficient lateral water mist shielding in traditional sealing structures, which is beneficial to reducing signal attenuation of the sensor body 1. Furthermore, the water-guiding threads 6 on the outer wall of the sensor body 1 will guide the water droplets to flow downward along the spiral path, preventing water droplets from lingering on the surface of the sensor body 1.
