[0035] like Figure 1 to Figure 4 As shown, a preferred embodiment of a connector with a thermal sensing module according to the present invention.

[0036] New energy storage connectors are generally connected to new energy battery management systems (BMS). The real-time temperature of new energy storage connectors during use is one of the intuitive representations of their usage status. Failures and abnormalities in the adapter connection couplings within the energy storage connector will be quickly reflected in its temperature changes. If problems or failures occur inside the energy storage connector, the conductive conductor will heat up, and excessive temperature can easily cause a fire. Therefore, real-time monitoring of the temperature of new energy storage connectors is a necessary measure to quickly detect failures and abnormalities in new energy storage connectors.

[0037] To solve the above problems, the present invention provides a connector with a thermal sensing module, including a plug 10, a socket 20 and a thermal sensing module 30, the plug 10 includes a plug shell 11 and a terminal 12 connected to the plug shell 11; the socket 20 includes a socket shell 21 and a pin 22 connected to the socket shell 21, the thermal sensing module 30 includes a sensing module 31, a control module 32 and an information feedback module 33, and the sensing module 31, the control module 32 and the information feedback module 33 are electrically connected; wherein, the plug 10 is adaptively connected to the socket 20, the thermal sensing module 30 is connected to the plug shell 11, one end of the sensing module 31 of the thermal sensing module 30 is in contact with the terminal 12 for sensing the internal temperature change of the high current connector, and the other end is connected to the control module 32 and the information feedback module 33.

[0038] The connector with a thermal sensing module provided by the present invention senses the internal temperature of the connector through the sensing module 31 of the thermal sensing module 30. When the temperature exceeds the preset value, the control module 32 controls the circuit of the information feedback module 33 to be turned on, and the information feedback module 33 will give a reminder, which can effectively prevent the connector from causing a fire due to excessive temperature, improve the safety of high-current connectors, and can also respond in time through the thermal sensing module 30 when a fault abnormality occurs inside the connector.

[0039] In one embodiment, the control module 32 includes a control component, which includes a control chip and its circuit. The control component presets a temperature value. When the sensing module 31 senses that the temperature inside the connector exceeds the preset temperature value, the control component controls the circuit of the information feedback module 33 to be turned on. The sensing module 31 includes a temperature sensor 311, which is a thermistor, a thermistor diode temperature sensor, or a digital temperature sensor.

[0040] In one embodiment, the information feedback module 33 includes a warning mark 331, and the plug housing 11 shows the warning mark 331. Figure 1 A thermistor is a sensor resistor whose resistance value changes with temperature. When the temperature inside the connector changes, the resistance value of the thermistor changes, causing the circuit current to change. The control component then controls the circuit conduction of the information feedback module 33, and the warning mark 331 lights up, reminding the staff that the connector may be faulty and that they should be checked in time. Warning marks include, but are not limited to, LED lights, buzzers, or color-changing indicator marks, and various warning marks can also be used in combination. For example, the combination of a color-changing indicator mark and a buzzer allows staff to quickly notice abnormalities in the connector.

[0041] In one embodiment, the information feedback module 33 includes a signal sending device, through which information is transmitted. When the circuit of the information feedback module 33 is turned on, the signal sending device sends a radio frequency signal to the signal receiving end. The signal receiving end also includes a data background and a terminal user end. The information feedback module 33 can also provide data feedback to the device and software. The signal receiving end can also be a mobile app or APP.

[0042] In one embodiment, the information feedback module 33 includes an information feedback device, such as a display screen, which can directly display the internal temperature of the connector. If there is any abnormality, it can be directly displayed on the display screen.

[0043] In one embodiment, the plug housing 11 includes a plug end 111 and a wiring end 112, wherein the plug end 111 is used to connect to the socket 20, and the wiring end 112 is used to connect to the wire. One end of the socket housing 21 is a plug end 211 connected to the plug 10, and a snap ring 213 is provided on the plug end 211; the other end of the socket housing 21 is a connection end 212, and the pin 22 extends from the connection end 212. The socket housing 21 has a locking member 113, and only the middle part of the locking member 113 is connected to the socket housing 21. The locking member 113 has a first end 1131 and a second end 1132, and neither the first end 1131 nor the second end 1132 is connected to the plug housing 11; the inner side of the first end 1131 of the locking member 113 has a snap tooth 1133.

[0044] The socket shell 21 has locking members 113 on both sides, which can enhance the locking degree of the plug 10 and the socket 20, so that the plug 10 and the socket 20 are not easy to separate. When the high-current connector plug 10 is plugged into the socket 20, it has a locked state and an unlocked state; in the locked state, the locking teeth 1133 of the locking member 113 conflict with the snap ring 213 of the plug end 211, so that the socket 20 and the plug 10 cannot be separated; in the unlocked state, the locking teeth 1133 of the locking member 113 separate from the snap ring 213 of the plug end 211, so that the socket 20 and the plug 10 can be separated. When the second ends 1132 of the two locking members 113 of the plug shell 11 are pressed at the same time, the first end 1131 of the locking member 113 will be tilted, so that the locking teeth 1133 and the snap ring 213 no longer conflict, and the plug 10 and the socket 20 can be separated.

[0045] A connector with a thermal sensing module, comprising a plug 10, a socket 20 and a thermal sensing module 30, wherein the plug 10 comprises a plug shell 11 and a terminal block 12 connected to the plug shell 11; the socket 20 comprises a socket shell 21 and a pin 22 connected to the socket shell 21, and the thermal sensing module 30 comprises a sensing module 31, a control module 32 and an information feedback module 33, wherein the sensing module 31, the control module 32 and the information feedback module 33 are electrically connected; wherein the plug 10 is adaptably connected to the socket 20, the thermal sensing module 30 is connected to the plug shell 11, one end of the sensing module 31 of the thermal sensing module 30 is in contact with the terminal block 12 for sensing the internal temperature change of the high current connector, and the other end is connected to the control module 32 and the information feedback module 33.

[0046] The connector with a thermal sensing module described in the present invention can also be locked by a locking member 113 to prevent the plug 10 and the socket 20 from being separated during use.
