[0015] Reference Figure 1-5As shown, the present invention discloses a temperature-sensing integrated PCBA board for AC / DC charging sockets, comprising a main PCB board 1. A sub-PCB board 3 is connected to one side of the main PCB board 1 via a first pin connector 2. The pins of the pin connector 2 are soldered to the main PCB board 1 and the sub-PCB board 3, respectively. The sub-PCB board 3 is provided with a first thermally conductive silicone seat 4, which has a first slot 5 for insertion into the sub-PCB board 3, and at least one first temperature-sensing mounting groove 6 is provided in the first slot 5. A first temperature sensor 7 is soldered to the sub-PCB board 3 corresponding to the first temperature-sensing mounting groove 6. The detection surface of the first temperature sensor 7 is to be in contact with the first temperature-sensing mounting groove 6. The main PCB board 1 is provided with a set of AC terminal mounting holes 8, and a second thermally conductive silicone seat 9 is provided in the AC terminal mounting holes 8. The second thermally conductive silicone seat 9 has a second slot 10 for insertion into the main PCB board 1, and at least one second temperature-sensing mounting groove 11 is provided in the second slot 10. A second temperature sensor 12 is soldered to the main PCB board 1 corresponding to the second temperature-sensing mounting groove 11. When this temperature-sensing integrated PCBA assembly is assembled into the AC / DC charging socket, the end faces of the first thermally conductive silicone base 4 and the second thermally conductive silicone base 9 should respectively fit into the DC terminal and AC terminal inside the AC / DC charging socket.

[0016] Preferably, the front end of the first thermally conductive silicone base 4 is provided with a first arc-shaped contact surface 13, and the front end of the second thermally conductive silicone base 9 is provided with a second arc-shaped contact surface 14.

[0017] Preferably, the first slot 5 of the first thermally conductive silicone base 4 is provided with first retaining ribs 15 on both sides to engage with the sides of the sub-PCB board 3.

[0018] Preferably, the second slot 10 of the second thermally conductive silicone base 9 is provided with second retaining ribs 16 on both sides, and the AC terminal mounting hole 8 of the main PCB board 1 is provided with a retaining groove 17 that engages with the second retaining ribs 16. This improves the connection strength between the second thermally conductive silicone base 9 and the main PCB board 1 and prevents it from falling off.

[0019] Preferably, one side of the main PCB board 1 is provided with a second pin connector 18 that is connected to the circuits of the first temperature sensor 7 and the second temperature sensor 12. The second pin connector 18 can be mated with an external plug, which can conveniently output the detection signal.

[0020] Preferably, a set of spring-loaded terminals 19 are soldered to the surface of the main PCB board 1. The rear end of the signal terminal in the AC / DC charging socket can directly contact the spring-loaded terminals 19, and the signal can be conveniently output through the main PCB board 1 and the second pin connector 18.

[0021] Preferably, both the main PCB board 1 and the sub-PCB board 3 are provided with positioning holes 20. The positioning holes 20 are positioned and engaged with the positioning posts inside the AC / DC charging socket to improve the stability of the assembly.

[0022] Preferably, the first slot 5 has a first temperature-sensing mounting groove 6 on both its upper and lower sides, and the second slot 10 has a second temperature-sensing mounting groove 11 on both its upper and lower sides.
