Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a waterproof arc light emission detection sensor. Background Technology

[0002] An arc light sensor is a high-precision photoelectric detection device whose core function is to output different voltage values ​​by sensing changes in light intensity. The design principle of this sensor is based on the photoelectric effect, which states that there is a direct proportional relationship between light intensity and output voltage. When the light intensity changes, the sensor outputs a corresponding voltage value, thus accurately determining the presence of abnormal light. This characteristic makes arc light sensors promising for applications in industrial monitoring, safety protection, and environmental detection.

[0003] However, the arc flash sensors commonly found on the market have some limitations in their structural design. Specifically, the outer shell and inner core of these sensors are typically assembled using a threaded connection. While this assembly method ensures structural stability to some extent, its waterproof performance is not ideal in practical applications, especially in humid environments. Prolonged exposure to moisture allows water vapor and humidity to gradually penetrate the sensor's interior, affecting its performance, reducing detection accuracy, and potentially causing malfunctions. Furthermore, the threaded assembly method also presents some problems during production, such as relatively long assembly times, which not only increases production costs but also reduces production efficiency.

[0004] To address these issues and improve the reliability and production efficiency of arc sensors, it is necessary to optimize and improve the existing sensor structure. Utility Model Content

[0006] To achieve the above objectives, the waterproof arc light emission detection sensor provided by this utility model includes a housing, a sensor body, a sensor core, a gland, and a cable; wherein, The housing is a hollow tubular structure, with its front end connected to the sensor core and its rear end connected to the gland head; wherein, the inner wall of the front end is provided with a limiting part and a locking part; The sensor body is electrically connected to the cable; The sensor core is used to fix the sensor body within the housing. A limiting structure, a sealing structure, and a hook structure are sequentially arranged around the outer periphery of the sensor core. The limiting structure is positioned within the limiting portion of the housing; the sealing structure is in close contact with the inner wall of the housing; and the hook structure is engaged with the locking portion of the housing. The head end of the gland is connected to the housing, and a sealing ring is provided at the connection. The tail end is provided with a through hole for the cable to pass through, and a locking nut for locking the cable is provided on the outer periphery of the tail end.

[0007] Furthermore, the sensor core is made of elastic soft rubber material.

[0008] Furthermore, the sealing structure is a multi-ring sealing platform.

[0009] Furthermore, both the hook structure and the locking part are double-layered structures.

[0010] Furthermore, the sensor core is integrally formed with the sensor body through injection molding.

[0011] The waterproof arc light emission detection sensor of this utility model, through the cooperation of the limiting part and the limiting structure, and the cooperation of the locking part and the hook structure, can quickly assemble the sensor core into the housing, reducing assembly time; at the same time, the sealing structure effectively prevents water and gas from entering the sensor, effectively achieving a waterproof effect.

[0018] As shown in the figure, the waterproof arc light emission detection sensor provided by this utility model includes a housing 1, a sensor body 2, a sensor core 3, a gland 4, and a cable 5; wherein,

[0019] The housing 1 is a hollow tubular structure, with its front end connected to the sensor core 3 and its rear end connected to the gland 4. The inner wall of the front end has a limiting part 11 and a locking part 12 arranged sequentially from the outside in. The limiting part 11 is a limiting platform structure located at the outermost side of the housing 1, used to limit the sensor core 3. The locking part 12 is a double-layer locking platform structure used to lock the sensor core 3 within the housing 1. The outer wall of the front end has external threads, and the inner wall of the rear end has internal threads.

[0020] The sensor body 2 includes a sensor 21 and a circuit board 2 connected to the sensor 21.

[0021] The sensor core 3 includes components for fixing the sensor body 2 within the housing 1. Specifically, the outer periphery of the sensor core 3 is sequentially provided with a limiting structure 31, a sealing structure 32, and a hook structure 33. The limiting structure 31 is a limiting step, which can be limited to the front end of the housing 1 by the limiting part 11 of the housing 1, preventing the sensor core 3 from moving to the rear end of the housing 1. The sealing structure 32 consists of two interference-fit sealing platforms, which can tightly contact the inner wall of the housing 1. The sealing platforms undergo elastic deformation upon compression, achieving a sealing and waterproof effect. The hook structure 33 is a double-layer hook structure, which can be locked into the locking part 12 of the housing 1, securing the sensor core 3 inside the housing 1. After the sensor core 3 is assembled with the housing 1, the hook structure 33 of the sensor core 3 cooperates with the locking platform structure of the housing 1 to prevent the sensor core 3 from detaching from the front end of the housing 1. Preferably, the sensor core 3 is made of elastic soft rubber material and is integrally molded with the sensor body 2 by injection molding.

[0022] The gland 4 is a metal structure with an external thread at its head end that connects to the housing 1. An O-ring 41 is fitted around the outer circumference of the external thread. The housing 1 and the metal gland 4 are screwed together. Waterproofing is achieved between the housing 1 and the gland 4 by compressing the O-ring 41. A locking nut 42 is provided on the outer wall of the tail end of the gland 4. A through hole for the cable 5 is provided at the tail end, and a waterproof ring is installed inside the part that contacts the cable 5. When the locking nut 42 is tightened, waterproofing is achieved at the tail end of the gland 4 by compressing the waterproof ring inside the gland 4 and the cable 5.

[0023] The assembly method of each component of the waterproof arc light emission detection sensor provided by this utility model is as follows:

[0024] The sensor core 3 is injection molded and tightly connected to the sensor body 2; the injection-molded sensor body 2 is welded to the cable 5; the cable 5 enters from the front end of the housing 1 and exits from the rear end. The sensor body 2, the limiting structure 31, the sealing structure 32, and the limiting structure 33 are sequentially inserted into the housing 1. After the limiting structure 31 is tightly connected to the limiting part 11 of the housing 1, the assembly is in place; then the cable 5 enters from the head end of the gland 4 and exits from the tail end, and is screwed to the housing 1. The locking nut 42 at the tail end locks and compresses the cable 5, and the whole assembly is in place.

[0025] In summary, the waterproof arc emission detection sensor of this invention, through the cooperation of the limiting part 11 and the limiting structure 21, and the cooperation of the locking part 12 and the hook structure 22, allows for the rapid assembly of the sensor core 3 into the housing 1, reducing assembly time. Simultaneously, the sealing structure 32 effectively prevents moisture and gas from entering the sensor 21, achieving waterproofing. Furthermore, the gland 4 is equipped with a sealing ring 41 and a waterproof ring at its head and tail ends, respectively, effectively ensuring a sealed and waterproof effect at the gland 4.
