[0027] The specific embodiments of the communication connection assembly of the sensor and the refrigerant sensor of the present application are described below in conjunction with FIGS. 1-4.

[0028] As shown in FIGS. 1 and 2, the present application provides a communication connection assembly of a sensor, comprising: a socket portion 110 provided on a shell 100 of a refrigerant sensor, the socket portion 110 is provided with a plug slot 111 open to the outside, and a plug pin 112 connected to a communication module of the refrigerant sensor is arranged in the plug slot 111; a communication cable 120, an end portion of the communication cable 120 is provided with a plug portion 121 adapted to the shape of the plug slot 111, and the plug portion 121 is provided with a plug hole 122 corresponding to the plug pin 112; in the connected state of the communication connection assembly, the plug portion 121 of the communication cable 120 is plugged and matched with the plug slot 111 of the socket portion 110, and the plug pin 112 is plugged and matched with the plug hole 122, so that the communication module is in communication with the communication cable 120. Through the cooperation of the socket portion 110 and the plug slot 111 with the plug portion 121 and the plug hole 122 of the communication cable 120, detachable connection of the communication module and the communication cable 120 is realized.

[0029] Specifically, the socket part 110 is arranged on the refrigerant sensor shell 100 and has a plug-in slot 111 open to the outside. The plug-in slot 111 is internally configured with pins 112, which are directly connected to the communication module inside the refrigerant sensor. The socket part 110 provides a physical interface for the communication cable 120 to realize the communication connection between the communication module and the external line. The communication cable 120 is used for data transmission, and one end thereof is provided with a plug part 121, which is matched in shape with the plug-in slot 111 of the socket part 110. The plug part 121 is provided with a plug hole 122 at the end thereof, and the position and number of the plug hole 122 correspond to the pins 112 in the socket part 110, ensuring that the two can be accurately and correctly docked. When the communication connection assembly is in a connected state, the plug part 121 of the communication cable 120 is inserted into the plug-in slot 111 of the socket part 110 on the refrigerant sensor shell 100, and the plug hole 122 of the plug part 121 is accurately aligned with the pins 112 of the socket part 110 and forms a plug-in fit.

[0030] Through the above communication connection assembly, the disassembly and replacement of the communication cable 120 are relatively simple and fast, and can be completed without complex tools or professional knowledge, and at the same time, it is also convenient for maintenance personnel to quickly diagnose and repair faults, thereby reducing maintenance costs. In addition, this independent plug-in type communication connection also allows the length of the communication cable 120 to be flexibly adjusted, thereby improving the installation adaptability and overall performance of the system.

[0031] According to the communication connection assembly of the sensor of the present application, the plug part 121 of the communication cable 120 is further refined in design to enhance the reliability and environmental adaptability of the connection. Specifically, the plug part 121 preferably includes a wiring end and a plug-in end; the plug hole 122 is arranged on the plug-in end; a sealing ring 123 is arranged between the wiring end and the plug-in end; and in the connected state, the sealing ring 123 is in sealing fit with the plug-in slot 111.

[0032] Specifically, in order to improve the protection level such as waterproof and dustproof, the sealing ring 123 is arranged between the wiring end and the plug-in end. In the plug-in fit state of the plug part 121 and the socket part 110, the sealing ring 123 is in close contact with the plug-in slot 111 of the socket part 110, forming a sealing fit. This sealing design can effectively prevent external factors such as water vapor and dust from affecting the communication connection, thereby ensuring that the communication connection can maintain good stability and reliability even in harsh environments.

[0033] In order to achieve better sealing performance, preferably, a multiple sealing structure is provided. According to the communication connection assembly of the sensor of the present application, a plurality of sealing rings 123 are evenly distributed along the length direction of the plug portion 121. When the plug portion 121 is inserted into the insertion slot 111 of the socket portion 110, the plurality of sealing rings 123 form a plurality of sealing barriers at different positions, thereby significantly improving the waterproof and dustproof capability.

[0034] Alternatively, in another embodiment, the sealing ring 123 has a progressive layered structure, and a plurality of annular protrusions 124 for sealingly engaging with the insertion slot 111 are provided on the sealing ring 123 along the length direction of the plug portion 121. The sealing ring 123 itself has a plurality of annular protrusions 124 arranged along the length direction of the plug portion 121. Each annular protrusion 124 can form an independent sealing engagement with the inner wall of the insertion slot 111, similar to the effect of the multiple sealing rings 123, but achieved by a single sealing ring 123, thereby reducing the number of components and simplifying the assembly process.

[0035] In order to enhance the stability between the plug portion 121 and the socket portion 110, as shown in FIGS. 2, 3 and 4, according to the communication connection assembly of the sensor of the present application, the inner wall of the insertion slot 111 is formed with a stepped structure 113. In the connected state, the insertion end is inserted between the stepped structure 113, and the stepped structure 113 is stopped on one side of the sealing ring 123. When the plug portion 121 is connected to the socket portion 110, the insertion end of the plug portion 121 can be accurately inserted between the stepped structure 113. When the insertion end is fully inserted, one side of the stepped structure 113 will be in close contact with the sealing ring 123, forming a physical stop, thereby ensuring that the plug portion 121 will not be inserted too deeply.

[0036] In order to improve the accuracy and convenience of the connection between the plug portion 121 and the socket portion 110, according to the communication connection assembly of the sensor of the present application, the inner surface of at least one side of the stepped structure 113 is provided with a guide ridge 114; and the insertion end is provided with a guide groove 125 adapted to the guide ridge 114. The cooperation of the guide ridge 114 and the guide groove 125 can help to automatically align the position of the pin 112 and the socket 122 during the insertion of the plug portion 121 into the socket portion 110, thereby ensuring that the two can be accurately and correctly connected. Moreover, the specific shape and positional relationship of the guide ridge 114 and the guide groove 125 can also help the operator to determine the correct insertion direction of the plug portion 121. In actual operation, only when the plug portion 121 is inserted at the correct angle and direction, the guide groove 125 can smoothly slide along the guide ridge 114, thereby avoiding the situation of reverse or incorrect direction insertion, simplifying the installation steps and reducing the maintenance difficulty.

[0037] As shown in FIG. 3 and FIG. 4, according to the communication connection assembly of a sensor of the present application, the opening end of the plug-in slot 111 is provided with a chamfer structure 115, which forms a wide-angle shape at the opening end of the plug-in slot 111. The chamfer structure 115 at the opening end of the plug-in slot 111 not only simplifies the installation process of the plug-in head 121, improves the convenience and efficiency of operation, but also enhances the overall performance and reliability of the communication connection assembly by reducing the potential risk of the sealing ring 123 during the docking process.

[0038] Specifically, the sealing ring 123 needs to form a close fit with the inner wall of the plug-in slot 111 to achieve the best sealing effect. The guiding effect of the chamfer structure 115 ensures that the sealing ring 123 can easily enter the sealing area of the plug-in slot 111 when the plug-in head 121 is inserted. Moreover, since the sealing ring 123 is usually made of a material with a certain elasticity, the friction during the insertion process may cause unnecessary pressure or damage to it, thereby affecting the integrity and sealing performance of the sealing ring 123. The chamfer structure 115 reduces the frictional resistance that the sealing ring 123 bears during the installation process through its smooth transition surface, protecting the sealing ring 123 from damage. The wide-angle transition surface formed by the chamfer structure 115 at the opening end of the plug-in slot 111 can be a wedge surface or an arc surface as shown in the figure.

[0039] As shown in FIG. 1 and FIG. 4, according to the communication connection assembly of a sensor of the present application, the plug-in head 121 is provided with a pressure buckle 126, which has a locking groove 127 that is adapted to the limiting protrusion 116. In the connected state, the locking groove 127 of the pressure buckle 126 forms a limiting fit with the limiting protrusion 116, thereby ensuring the stability of the connection and preventing the plug-in head 121 from loosening due to external forces (such as vibration or accidental collision). The limiting fit ensures the stability of the connection, and when disassembly is required, the operator only needs to exert appropriate force to release the pressure buckle 126, so that the plug-in head 121 and the plug-in base 110 can be easily separated.

[0040] In the above structure, the limiting protrusion 116 can be provided on the inner wall of the plug-in slot 111 of the plug-in base 110, and when the plug-in head 121 is inserted into the plug-in slot 111, the pressure buckle 126 will enter the plug-in slot 111 together with the plug-in head 121. During the connection process, the locking groove 127 on the pressure buckle 126 naturally aligns with the limiting protrusion 116 and forms a limiting fit, ensuring the firm combination of the plug-in head 121 and the plug-in base 110.

[0041] According to the preferred communication connection assembly of the sensor, the press buckle 126 is connected to the plug part 121 through the elastic arm 128, and the limiting protrusion 116 is arranged on the outer surface of the socket part 110. In the connected state, the press buckle 126 is in limiting cooperation with the limiting protrusion 116 on the outer side of the socket part 110. Specifically, when the plug part 121 is inserted into the socket part 110, the press buckle 126 can be temporarily deformed due to the elastic property of the elastic arm 128 until the plug part 121 is completely in place. At this time, the press buckle 126 is in limiting cooperation with the limiting protrusion 116 on the outer side of the socket part 110, the elastic arm 128 returns to the original state, and the locking groove 127 of the press buckle 126 is in close contact with the limiting protrusion 116, thereby locking the position of the plug part 121.

[0042] Preferably, limiting baffle plates are arranged on both sides of the limiting protrusion 116 to assist the alignment of the locking groove 127 of the press buckle 126 with the limiting protrusion 116 and prevent the press buckle 126 from shaking. In addition, a slope structure is preferably arranged on the outer side of the limiting protrusion 116 to enable the press buckle 126 to automatically lift along the slope structure during the insertion of the plug part 121.

[0043] The refrigerant sensor provided by the present application is described below, and the refrigerant sensor described below can be correspondingly referred to the communication connection assembly of the sensor described above.

[0044] The present application also provides a refrigerant sensor provided with the communication connection assembly of the sensor of any one of the above embodiments. Preferably, the shell 100 of the refrigerant sensor is provided with the socket part 110 with the outwardly open plug slot 111, and the inside is equipped with the plug pin 112 connected with the sensor communication module, thereby providing a stable basis for the connection of the communication cable 120. One end of the communication cable 120 is designed with the plug part 121 matched with the plug slot 111 of the socket part 110, and the plug part 121 contains the plug hole 122 corresponding to the plug pin 112 of the socket part 110, thereby ensuring the accuracy and stability of the electrical connection. At the connection between the plug part 121 and the socket part 110, the sealing ring 123 with a progressive layered sealing structure is adopted, thereby effectively preventing external factors such as moisture and dust from interfering, and ensuring the environmental adaptability of the connection assembly and the continuity of signal transmission. According to the cooperation between the guiding ridge 114 and the guiding sliding groove 125 and the locking design of the limiting protrusion 116 and the press buckle 126, not only the connection process is simplified, the accuracy of assembly is improved, but also the firmness of the connection is ensured, thereby avoiding the loosening of the connection caused by external vibration or impact.

[0045] According to the refrigerant sensor of the present application, a power supply module is provided; the power supply module comprises a battery assembly integrated in the refrigerant sensor, or the power supply module comprises a power supply circuit independent of the communication connection assembly. Specifically, in one embodiment, the power supply module comprises a battery assembly integrated in the refrigerant sensor. This design means that the sensor itself carries the power supply, without the need for external power supply, making the deployment of the sensor more flexible and not limited by the location of the power supply. The battery assembly is preferably a 5V power supply module. In another embodiment, the power supply module comprises a power supply circuit independent of the communication connection assembly. By separating the power supply, interference such as voltage fluctuations or electromagnetic interference affecting signal transmission is avoided. Independent power supply makes the length of the communication cable 120 more flexible, not constrained by power supply requirements, thereby optimizing the installation layout, reducing signal attenuation and improving communication quality.

[0046] Through the above embodiments, the refrigerant sensor of the present application not only provides diversity in power supply, but also solves the limitations brought by the integration of power supply and communication in traditional sensors. Whether it is in the self-sufficient mode of built-in battery assembly or in the separated power supply through independent power supply circuit, the performance of the communication connection assembly is not affected by the power supply factor, providing users with a more stable, efficient and adaptable sensor solution.
