Description

TECHNICAL FIELD

[0001] The utility model relates to sensor technical field, concretely is a sensor connecting structure with waterproof structure. BACKGROUND

[0002] In many fields such as modern industrial production, environmental monitoring and scientific research, sensors play a crucial role. For example, in water quality analysis, sensors are needed to accurately detect various parameters of water bodies; in industrial process control, sensors are used to monitor various physical and chemical quantities in real time during the production process to ensure the safety and stability of the production process.

[0003] At present, various sensors on the market, whether used for water quality analysis or industrial process monitoring, often have moisture problems between the sensor socket and the plug connecting line. For example, in some humid industrial environments or outdoor water quality monitoring scenarios, because the sensor is exposed to humid air for a long time, water can easily seep through the gap between the sensor socket and the plug connecting line, causing the metal connector to rust and corrode. This not only affects the electrical performance of the sensor, but also causes signal transmission to be disturbed, resulting in errors in the data collected by the sensor, and thus affecting the accuracy and reliability of the entire monitoring or control system.

[0004] To solve the problem of moisture in the sensor, the traditional method is mainly to take some simple waterproof measures at the connector part of the sensor, such as applying sealant, installing a waterproof cover, etc. However, these methods have certain limitations. For example, applying sealant may age and crack over time, losing its waterproof effect; although the waterproof cover can block water to some extent, it cannot completely prevent water from seeping through the gap in the connector, and it is also troublesome to install and remove the waterproof cover, which is not conducive to the maintenance and repair of the sensor.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] In the embodiment, by adopting wireless charging and wireless signal transmission technology, the metal connector design between the socket and the plug connection line in the traditional sensor is avoided, which fundamentally eliminates the risk of moisture seeping through the connector gap. At the same time, the use of sealing ring one 16, sealing ring two 15, and nut sleeve 17 in the waterproof mechanism further enhances the waterproof performance of the sensor. Even in a humid environment, the internal circuit of the sensor can be effectively protected from moisture erosion, ensuring the normal operation of the sensor.

[0029] As shown in Figure 3 and Figure 4 , a waterproof mechanism is provided between the cable end 5 and the sensor body 1. The waterproof mechanism includes an annular groove 14, which is provided on the outside of the cable end 5. The sealing ring two 15 is sleeved in the annular groove 14. The sealing ring one 16 is sleeved on the outside of the threaded head 2 near the sensor body 1. The waterproof mechanism also includes a nut sleeve 17, which is threadedly connected to the outside of the sensor body 1 and the cable end 5.

[0030] In the embodiment, the metal connector is avoided from being damp and rusty, and the signal transmission of the sensor is not disturbed by moisture, greatly improving the stability and reliability of signal transmission. The wireless signal transmission method also reduces the problems of signal attenuation and electromagnetic interference that may exist in traditional wired connection, so that the data collected by the sensor can be transmitted to external equipment more accurately, improving the precision of the monitoring and control system.

[0031] Working principle: When an external power source supplies power to the power conversion module 10 inside the cable end 5, the power conversion module 10 converts the input electrical energy into high-frequency AC power suitable for wireless charging, and transmits the AC power to the wireless charging transmitting coil 6 through the cable 12. After receiving the high-frequency AC power, the wireless charging transmitting coil 6 generates an alternating magnetic field around it. The upper end of the detection end 3 inside the sensor body 1 is provided with a wireless charging receiving coil 8 opposite to the position of the wireless charging transmitting coil 6. When the alternating magnetic field generated by the wireless charging transmitting coil 6 passes through the wireless charging receiving coil 8, according to the law of electromagnetic induction, an induced electromotive force is generated in the wireless charging receiving coil 8, which in turn generates an induced current, thereby realizing the wireless transmission of electrical energy from the cable end 5 to the inside of the sensor body 1, providing power support for the normal operation of the sensor. After the sensor's detection end 3 detects the corresponding physical or chemical quantity, it transmits the detected signal to the wireless signal transmitter 9. The wireless signal transmitter 9 modulates the sensor signal and then transmits the signal wirelessly. The wireless signal receiver 7 inside the cable end 5 is remotely connected to the wireless signal transmitter 9 and can receive the signal sent by the wireless signal transmitter 9. After receiving the signal, the wireless signal receiver 7 transmits the signal to the wireless communication chip 11. The wireless communication chip 11 demodulates and decodes the signal and then transmits the processed signal to an external device through the cable 13, thereby realizing the wireless transmission of the sensor detection signal. A waterproof mechanism is provided between the cable end 5 and the sensor body 1. The upper and lower ends of the cable end 5 are provided with annular grooves 14. A second sealing ring 15 is fitted inside the annular groove 14. A first sealing ring 16 is fitted on the outside of the threaded head 2 near the sensor body 1. When the sensor body 1 and the cable end 5 are connected by a nut sleeve 17, the first sealing ring 16 and the second sealing ring 15 will be squeezed, thus tightly fitting at the connection between the sensor body 1 and the cable end 5, forming an effective sealing structure to prevent moisture from seeping into the sensor from the connection.

[0032] It should be noted that the sensor in this device is a dissolved oxygen sensor.
