Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to a sensor structure. Background Technology

[0002] A sensor is a device that can sense and respond to changes in the external environment, such as physical, chemical, or biological changes. It can convert the sensed non-electrical information into electrical signals or other forms of signals.

[0003] A search revealed a Chinese patent for an improved sensor structure, publication number CN219319446U, which includes a lens located on the front side of a lens cover, an adapter cover screwed onto the lens cover, and a housing connected to the adapter cover. The housing has a PCB substrate mounting chamber located at the front and a transformer isolation chamber connected to the rear of the PCB substrate mounting chamber. A circuit board assembly is located in the PCB substrate mounting chamber.

[0004] The front shell of the aforementioned device is designed with three parts: a lens, a lens cover, and an adapter cover. This design is very flexible and allows for various combinations of appearance styles by replacing different lenses, lens covers, or adapter covers. The rear shell of the product is designed with two parts: a first side cover and a second side cover. This design facilitates the secure fastening of the security card assembly inside the second side cover, thereby improving the mechanical strength of the security card.

[0005] However, its components are directly aligned and connected and fixed by bolts or clips, resulting in poor sealing performance. When used in humid environments or in contact with liquids, moisture can easily seep into the sensor, causing a short circuit and preventing the sensor from working properly or even being damaged. In addition, the poor sealing makes it susceptible to external electromagnetic interference. In a strong electromagnetic field environment, electromagnetic waves can pass through its gaps, interfering with the internal circuits, causing errors in the sensing data and affecting the reliability of the data. Utility Model Content

[0006] The purpose of this invention is to provide a sensor structure that can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sensor structure includes a sensor housing, an aviation plug one, and an aviation plug two. A PCB board is disposed at the front position inside the sensor housing, and an antenna module adapted to the PCB board is installed at the rear position inside the sensor housing. Mounting slots adapted to the PCB board and the antenna module are respectively opened at the front and rear ends of the sensor housing.

[0009] A front cover plate is installed in the mounting groove at the front end of the sensor housing by fixing bolts. A rear cover plate is installed in the mounting groove at the rear end of the sensor housing. An upper end cover and a lower end cover are respectively installed at the upper and lower ends of the sensor housing by connecting bolts. A sealing ring is provided at the connection between the upper end cover and the lower end cover and the sensor housing. A sealing ring is provided at the connection between the front cover plate and the sensor housing. A sealing ring is provided at the connection between the rear cover plate and the sensor housing.

[0010] Preferably, a lead-in port is provided at the upper rear end of the sensor housing, and a rear cover plate one and a rear cover plate two are installed in sequence inside the lead-in port.

[0011] Preferably, the end of the rear cover plate three away from the sensor housing is detachably fitted with a protective cover, and the rear cover plate three is provided with a port that is compatible with the antenna module.

[0012] Preferably, a light guide plate is installed at the bottom of the lower end cover by connecting bolts, and a sealing socket is provided at the bottom of the lower end cover to be compatible with the aviation plug, and the aviation plug is detachably installed at the bottom of the lower end cover through the sealing socket.

[0013] Preferably, the top of the upper cover is provided with a sealing socket two that is compatible with the aviation plug two, and the aviation plug two can be detachably installed on the top of the upper cover through the sealing socket two.

[0014] Preferably, the outer walls of the sensor housing, lower end cover, and upper end cover are coated with a fluorocarbon waterproof coating, and the outer wall of the sensor housing is provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model improves overall sealing performance by setting sealing rings two, three, and one. Since the PCB board is fixed inside the sensor housing, the connection points between the front cover, rear cover three, lower end cover, and sensor housing are equipped with sealing rings two, three, and one, thereby reducing the probability of moisture seeping into the sensor housing when used in humid environments or in contact with liquids. At the same time, the good sealing performance prevents dust from entering the sensor housing in dusty factory workshops, thereby reducing the probability of frequent misjudgments by the PCB board.

[0017] By setting up aviation plug one and aviation plug two in conjunction with the upper and lower end covers, various mechanical stresses during the operation of the sensor housing can be reduced, ensuring that the sensor housing maintains a stable connection under harsh environments such as vibration and impact, reducing the risk of loose connection and signal interruption. At the same time, multiple sealing rings can be used to achieve all-round sealing, effectively preventing external contaminants from entering the sensor housing, ensuring connection stability, and resisting certain electromagnetic interference, which helps to improve the accuracy of sensing data.

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. Example 1

[0023] Combination Figures 1-3 A sensor structure includes a sensor housing 1, an aviation plug 7, and an aviation plug 14. A PCB board 2 is disposed at the front of the interior of the sensor housing 1, and an antenna module 15 adapted to the PCB board 2 is installed at the rear of the interior of the sensor housing 1. Mounting slots adapted to the PCB board 2 and the antenna module 15 are respectively provided at the front and rear ends of the sensor housing 1.

[0024] See Figure 2 and Figure 3Furthermore, a front cover plate 3 is installed inside the mounting groove at the front end of the sensor housing 1 by fixing bolts. A rear cover plate 16 is installed in the mounting groove at the rear end of the sensor housing 1. An upper end cover 4 and a lower end cover 5 are respectively installed at the upper and lower ends of the sensor housing 1 by connecting bolts. A sealing ring 8 is provided at the connection between the upper end cover 4 and the lower end cover 5 and the sensor housing 1. A sealing ring 9 is provided at the connection between the front cover plate 3 and the sensor housing 1. A sealing ring 10 is provided at the connection between the rear cover plate 1 and the sensor housing 1. A lead wire port is provided at the upper position of the rear end of the sensor housing 1, and a rear cover plate 11 and a rear cover plate 22 are installed in sequence in the lead wire port. A protective cover 13 is detachably installed at the end of the rear cover plate 16 away from the sensor housing 1. A through-hole that is compatible with the antenna module 15 is provided on the rear cover plate 16.

[0025] Specifically, after the PCB board 2 and the antenna module 15 are installed inside the sensor housing 1, the wiring points or openings can be sealed through the front cover 3, rear cover 11, rear cover 2 12, antenna module 15, rear cover 3 16, lower end cover 5, and upper end cover 4. A sealing ring 2 9 is provided at the connection between the front cover 3 and the sensor housing 1, and a sealing ring 3 10 is provided at the connection between the rear cover 3 16 and the sensor housing 1. At the same time, a sealing ring 1 8 is provided at the connection between the lower end cover 5 and the upper end cover 4 and the sensor housing 1. This can improve the overall sealing performance, thereby reducing the probability of moisture seeping into the sensor housing 1 when used in humid environments or in contact with liquids. At the same time, the good sealing performance can prevent dust from entering the sensor housing 1 in dusty factory workshops, reducing the probability of frequent misjudgments by the PCB board 2. Example 2

[0026] See Figure 2 Furthermore, based on Embodiment 1, the bottom end of the lower cover 5 is further provided with a light guide plate 6 installed by connecting bolts, and the bottom end of the lower cover 5 is provided with a sealing socket 1 that is compatible with aviation plug 1 7. The aviation plug 1 7 is detachably installed at the bottom end of the lower cover 5 through the sealing socket 1. The top end of the upper cover 4 is provided with a sealing socket 2 that is compatible with aviation plug 2 14. The aviation plug 2 14 is detachably installed at the top end of the upper cover 4 through the sealing socket 2. The outer walls of the sensor housing 1, the lower cover 5, and the upper cover 4 are coated with a fluorocarbon waterproof coating, and the outer wall of the sensor housing 1 is provided with anti-slip texture.

[0027] Specifically, when the sensor housing 1 is connected to the external circuit, the aviation plug 2 14 and aviation plug 1 7 can reduce various mechanical stresses on the sensor housing 1 during operation, ensuring that the sensor housing 1 maintains a stable connection under harsh environments such as vibration and impact, reducing the risk of loose connection and signal interruption. At the same time, multiple sealing rings can be used to achieve all-round sealing, effectively preventing external contaminants from entering the interior of the sensor housing 1, ensuring the stability of the connection, and resisting certain electromagnetic interference, which helps to improve the accuracy of sensing data. Furthermore, aviation plug 2 14 and aviation plug 1 7 are not integrated with the sensor housing 1, so as to facilitate quick disassembly and replacement, simplifying the installation and maintenance process.

[0028] In actual operation, after the PCB board 2 and the antenna module 15 are installed in the sensor housing 1, the wiring points or openings can be sealed through the front cover plate 3, the rear cover plate 11, the rear cover plate 2 12, the antenna module 15, the rear cover plate 3 16, the lower end cover 5, and the upper end cover 4. The connection between the front cover plate 3 and the sensor housing 1 is provided with a sealing ring 2 9, the connection between the rear cover plate 3 16 and the sensor housing 1 is provided with a sealing ring 3 10, and the connection between the lower end cover 5 and the upper end cover 4 and the sensor housing 1 is provided with a sealing ring 1 8, which can improve the overall sealing performance.

[0029] This reduces the probability of moisture seeping into the sensor housing 1 when used in humid environments or in contact with liquids. At the same time, the good sealing performance prevents dust from entering the sensor housing 1 in dusty factory workshops, reducing the probability of frequent misjudgments on the PCB board 2.

[0030] When the sensor housing 1 is connected to the external circuit, the various mechanical stresses of the sensor housing 1 during operation can be reduced by the aviation plug 2 14 and aviation plug 1 7, ensuring that the sensor housing 1 maintains a stable connection under harsh environments such as vibration and impact, and reducing the risk of loose connection and signal interruption.

[0031] It can also be used with multiple sealing rings to achieve all-round sealing, effectively preventing external contaminants from entering the sensor housing 1, ensuring connection stability, resisting certain electromagnetic interference, and improving the accuracy of sensing data. Furthermore, aviation plug 2 14 and aviation plug 1 7 are not integrated with the sensor housing 1, so as to facilitate quick disassembly and replacement, simplifying the installation and maintenance process.

[0032] Through the synergistic effect of the aforementioned sealing components, the sensor housing 1 can effectively prevent external pollutants from entering the interior of the sensor housing 1 in harsh environments such as humidity, dust, and oil, thus preventing moisture condensation and dust accumulation inside the sensor housing 1, ensuring the stability and reliability of the connection, and extending its service life.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
