DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] A charging stand structure, such as Figure 1-Figure 3 As shown, including:

[0028] Power terminal 1;

[0029] A mounting plate 2 having a channel 21, through which the power terminal 1 passes;

[0030] Signal terminal 3;

[0031] The terminal claw 4 is used to clamp the signal terminal 3;

[0032] The mounting plate 2 has a slot 22, and the terminal claw 4 is partially located in the slot 22;

[0033] The sheet metal connector 5 is injection molded in the mounting plate 2, and the PIN pin protrudes from the mounting plate 2.

[0034] PIN needle 6, electrically connected to the terminal claw 4 through the sheet metal connector 5;

[0035] The PIN needle 6 protrudes from the mounting plate 2

[0036] The utility model aims to provide a charging seat structure capable of eliminating a circuit board to improve production efficiency, reduce costs and reduce failure rates by reducing electronic devices.

[0037] The power terminal 1 is used for power transmission. When the charging base is connected to an AC charging device or a DC charging device, the power terminal 1 is electrically connected to the plug-in terminal on the charging gun to transmit current. The signal terminal 3 is used to transmit control signals. The mounting plate 2 is an insulator, which is provided with a channel 21 and a slot 22. The power terminal 1 is arranged through the channel 21, and the signal terminal 22 is arranged in the slot 22. One end of the sheet metal connector 5 is connected to the terminal claw 4, and the other end is connected to the PIN pin 6. Multiple PIN pins 6 are gathered to form a low-voltage connector, which is convenient for plugging with the plug-in connector for signal transmission of the charging base. The sheet metal connector 5 is injection molded in an insulating shell. This structure replaces the circuit board and greatly reduces the cost and greatly improves the production efficiency. The terminal claw 4 clamps the signal terminal 3, which can not only transmit the signal of the signal terminal 3 but also stabilize the signal terminal 3.

[0038] In some embodiments, the terminal claw 4 and the PIN needle 6 are integrally formed with the sheet metal connector 5. The integrally formed design can not only improve production efficiency, but more importantly, can reduce connection voltage to reduce the occurrence of failures.

[0039] In some embodiments, the signal terminal 3 includes a columnar connection end 31, and the terminal claw 4 clamps the connection end 31. The columnar connection end 31 is suitable for inserting into the slot 22 from the side, and the entrance of the slot is slightly smaller than the diameter of the cross section of the connection end 31. When the connection end 31 is inserted into the slot 22, it is not easy to withdraw.

[0040] In some embodiments, Figure 2 As shown, the terminal claw 4 includes a first spring piece 41 abutting against the connection end 31 from the side and a second spring piece 42 abutting against the connection end 31 from the end. The multiple spring pieces work together to more advantageously clamp the signal terminal 3 and ensure more reliable signal transmission.

[0041] Furthermore, there are two first spring pieces 41, which are relatively arranged on both sides of the connection end 31. The two first spring pieces 41 clamp the connection end 31 from both sides to prevent the connection end 31 from colliding with the mounting plate 2 and making abnormal noise, and it is also easier to provide sufficient clamping force to ensure reliable electrical connection.

[0042] In some embodiments, there are multiple terminal claws 4, each of which is insulated from each other through a different sheet metal connector 5. A charging station may need to be provided with multiple different signal terminals 3, each of which is connected to a different sheet metal connector 5 and PIN pin 6 to transmit different signals.

[0043] In some embodiments, a groove 23 is provided beside the channel 21. Figure 2 As shown, the groove 23 has an opening 24 on one side facing the channel 21, and a temperature sensor 7 is arranged in the groove 23. The temperature sensor 7 passes through the opening 24 and contacts the power terminal 1. The temperature sensor 7 is electrically connected to the corresponding sheet metal connector 5 through a signal line. The power terminal 1 is often at a very high temperature when transmitting electric energy. In order to ensure safety, the temperature of the power terminal 1 needs to be monitored. The temperature sensor 7 is arranged in the groove 23. The temperature sensor 7 keeps in contact with the power terminal 1, so that the temperature of the power terminal 1 can be monitored in real time and the temperature signal can be transmitted through the corresponding sheet metal connector 5 and the PIN needle 6, so that the outside world can know the temperature information so as to respond in time when an abnormality occurs.

[0044] Furthermore, a thermally conductive silicone is provided between the temperature sensor 7 and the power terminal 1. The thermally conductive silicone can better fit the power terminal 1, so that the temperature sensor 7 can obtain more accurate temperature information.

[0045] Furthermore, a clamping portion 231 is provided on the groove 23 to prevent the temperature sensor 7 from coming out. The clamping portion 231 can clamp the temperature sensor 7 in the groove 23 to prevent it from coming out of the groove 23.

[0046] The utility model also provides a charging seat, including the charging seat structure and the charging seat shell as described above, the mounting plate 2 is arranged in the charging seat shell, the mounting plate 2 is provided with a plug-in portion 8, the PIN pin 6 is arranged in the plug-in portion 8, and the plug-in portion 8 is integrally formed with the mounting plate 2. Multiple signal terminals 3 are connected to different PIN pins 6 through different sheet metal connectors 5, and multiple PIN pins 6 are arranged in the plug-in portion 8, which are centrally connected to the plug interface to realize the signal transmission of the charging seat. The plug-in portion 8 is integrally formed with the mounting plate 2, which will be more convenient and the structure will be more stable.
