Description

Technical Field

[0001] This utility model relates to the field of high-voltage connector technology, and in particular to a high-voltage connector with a temperature monitoring module. Background Technology

[0002] In current technologies, the emergence of high-voltage connectors for temperature monitoring modules stems from the urgent need for reliability and safety of high-voltage connectors in multiple fields. In the field of new energy vehicles, with the rapid development of new energy vehicle technology, the large currents and voltages during driving and charging / discharging cause high temperature rises in various high-voltage system components. As the main components for kinetic energy transmission, some high-current high-voltage connectors can only serve a connection function and cannot monitor the temperature in real time. High current overload may cause the connector to overheat or even be damaged and burned, posing a safety hazard. Therefore, it is necessary to detect the temperature of high-voltage connectors and issue warning signals to ensure driving safety.

[0003] However, existing technologies still have shortcomings, such as the following:

[0004] In existing technologies, temperature monitoring of high-voltage connectors often relies on a single sensor. This method has significant drawbacks: once the sensor drifts or malfunctions, it can easily cause distortion of temperature detection data, making it difficult to accurately capture the overheating state of the connector. Consequently, overheating risks cannot be detected in time, posing safety hazards to equipment operation. Summary of the Invention

[0005] The purpose of this invention is to provide a high-voltage connector with a temperature monitoring module, so as to solve the problem mentioned in the background art that the temperature monitoring of existing high-voltage connectors mostly relies on a single sensor.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-voltage connector with a temperature monitoring module includes a socket component, a plug component installed at one end of the left side of the socket component, a temperature detection structure slidably connected to the inner side of the top of the plug component, the plug component including a plug housing, a high-voltage current transmission line installed at one end of the left side of the plug housing, an installation frame installed at the top of the plug housing, and a mating groove opened at one end of the right side of the plug housing.

[0017] 1. This high-voltage connector innovatively employs a combination of routine and re-inspection thermistors, along with corresponding routine and re-inspection modules, forming a dual detection mechanism. The routine detection module handles regular temperature monitoring, while the re-inspection module performs intermittent checks and compares the data with the routine data, effectively avoiding misjudgments caused by the failure or error of a single detection component.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a high-voltage connector with a temperature monitoring module includes a socket component 1, and a plug component 2 is installed at one end of the left side of the socket component 1 for installing a high-voltage wire. A temperature detection structure 3 is slidably connected to the inner side of the top of the plug component 2 for detecting temperature. The plug component 2 includes a plug housing 21, and a high-voltage current transmission line 22 is installed at one end of the left side of the plug housing 21 for transmitting current. A mounting frame 23 is installed at the top of the plug housing 21 for installing the temperature detection structure 3. A mating groove 24 is provided at one end of the plug housing 21 for mating with the socket component 1. The socket component 1 includes a socket plate 11, and a socket interface 12 is installed at one end of the right side of the socket plate 11 for connecting other devices. The outer wall of the socket component 1 has a fixed threaded hole 13 for easy fixing of the socket component 1 to other equipment. The outer wall of the inner side of the docking groove 24 is equipped with a docking interface 241 for docking with the socket panel 11. The top of the inner side of the docking groove 24 is equipped with a daily thermistor 243 and a repeat thermistor 242, both for detecting temperature. The inner cavity of the docking groove 24 is equipped with a buffer ring 244 to prevent current interference to the daily thermistor 243 and the repeat thermistor 242. The top of the mounting frame 23 is equipped with a first indicator light 231 for normal detection and alarm, and a second indicator light 233 for repeat detection and alarm. The two sides of the inner side of the mounting frame 23 are equipped with limit slides 232 for limiting the fixing plate 31.

[0027] It should be noted that in this embodiment, the plug housing 21 and the socket panel 11 are assembled together via the high-voltage current transmission line 22. At the same time, the buffer ring 244 is used to buffer one end of the socket panel 11 during installation. Meanwhile, the socket interface 12 is connected to the power interface of the device. When the daily thermistor 243 and the repeat thermistor 242 receive current, the current flowing through them is detected by the daily thermistor 243 and the repeat thermistor 242. Then, the resistance value is calculated, and the resistance value is converted into a precise temperature and transmitted to the repeat detection module 37 and the daily detection module 36.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the temperature detection structure 3 includes a fixing plate 31, and a battery mounting slot 33 is provided on the left side of the top of the fixing plate 31. A replaceable battery 34 is installed inside the battery mounting slot 33. The replaceable battery 34 provides power to the daily detection module 36 and the re-inspection detection module 37 by being installed inside the battery mounting slot 33. A sealing groove 32 is provided on the left side of the top of the fixing plate 31. A sealing cover 35 is inserted into the inside of the sealing groove 32. The sealing cover 35 is threaded through the holes in the fixing plate 351 and the sealing groove 32 and connected to the threaded groove on the outer wall of the plug housing 21. Fastening plates 351 are installed on both sides, and bolts 352 are threaded onto the inner side of the fastening plates 351, thereby fastening the sealing cover 35 through the bolts 352. A conductive wire 341 is installed on one end of the replaceable battery 34, and a daily detection module 36 is installed on one end of the conductive wire 341. A daily signal transmission line 361 is installed on the outer wall of the left side of the daily detection module 36, so that the top end of the daily signal transmission line 361 is connected to the bottom of the first indicator light 231, so that the daily detection module 36 transmits the signal to the first indicator light 231. A recheck device is installed on one end of the conductive wire 341. The detection module 37 has a re-inspection signal transmission line 371 installed on its right outer wall. One end of the re-inspection signal transmission line 371 is connected to the bottom of the second indicator light 233, thus transmitting the signal from the re-inspection module 37 to the second indicator light 233. A storage slot 311 is provided at the bottom of the fixing plate 31 to facilitate the installation of the daily current transmission line 363 and the re-inspection current transmission line 373 at the bottom of the daily detection module 36 and the re-inspection module 37. A daily battery mounting plate 362 is installed on the left side of the bottom of the daily detection module 36, and the daily battery... A daily current transmission line 363 is installed on the inner side of the mounting plate 362. One end of the daily current transmission line 363 is installed on the top of the daily thermistor 243. The current is transmitted to the daily thermistor 243 through the daily detection module 36. A retest battery mounting plate 372 is installed on the right side of the bottom of the retest detection module 37. A retest current transmission line 373 is installed on the inner side of the retest battery mounting plate 372. One end of the retest current transmission line 373 is installed on the top of the retest thermistor 242. The current is transmitted to the retest thermistor 242 through the retest detection module 37.

[0029] It should be noted that, in this embodiment, when installing the temperature detection structure 3, the re-check signal transmission line 371 at the bottom of the second indicator light 233 and the daily signal transmission line 361 at the bottom of the first indicator light 231 should first be installed on the outer wall of the re-check detection module 37 and the daily detection module 36. Then, one end of the daily current transmission line 363 at the top of the daily thermistor 243 and the re-check current transmission line 373 at the top of the re-check thermistor 242 should be installed on the inner side of the daily battery mounting plate 362 and the re-check battery mounting plate 372, respectively. The installed temperature detection structure 3 is then inserted into the inner side of the mounting frame 23. The fixed plate 31 slides within the mounting frame 23 under the limiting slide 232, allowing the excess wires of the daily detection module 36 and the re-inspection detection module 37 to be tucked into the inner side of the mounting frame 23. Once the temperature detection structure 3 is installed, current can be transmitted using the daily detection module 36 and the re-inspection detection module 37. Normally, only the daily detection module 36 is activated to perform temperature detection, while the re-inspection detection module 37 performs intermittent detection. The temperature detected by the re-inspection detection module 37 is compared with the temperature detected by the daily detection module 36 to ensure the detection temperature.

[0030] The working principle of this utility model is as follows: When installing the temperature detection structure 3, the re-check signal transmission line 371 at the bottom of the second indicator light 233 and the daily signal transmission line 361 at the bottom of the first indicator light 231 are first installed on the outer wall of the re-check detection module 37 and the daily detection module 36. Then, one end of the daily current transmission line 363 at the top of the daily thermistor 243 and the re-check current transmission line 373 at the top of the re-check thermistor 242 are respectively installed on the inner side of the daily battery mounting plate 362 and the re-check battery mounting plate 372. The installed temperature detection structure 3 is inserted into the inner side of the mounting frame 23. The mounting frame 23 is limited and slid by the limiting slide 232 through the fixing plate 31. The excess wires installed on the outer wall of the daily detection module 36 and the re-check detection module 37 are tucked into the inner side of the mounting frame 23.

[0031] Once the temperature detection structure 3 is installed, current transmission can be achieved using the daily detection module 36 and the re-inspection detection module 37. Under normal circumstances, only the daily detection module 36 is activated to perform temperature detection. The re-inspection detection module 37 performs intermittent detection, and the temperature detected by the re-inspection detection module 37 is compared with that detected by the daily detection module 36 to ensure the detection temperature.

[0032] The plug housing 21 is assembled with the socket panel 11 via the high-voltage current transmission line 22. A buffer ring 244 is used to cushion the socket panel 11 during installation. The socket interface 12 is connected to the device's power interface. When the daily thermistor 243 and the repeat thermistor 242 receive current, they detect the current flowing through them, calculate the resistance value, and then convert the resistance value into a precise temperature reading, which is transmitted to the repeat detection module 37 and the daily detection module 36.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
