The locking plate 11 is engaged with the U-shaped frame 1. An assembly plate 12 is fixedly connected to the side of the cover plate 9 away from the sealing plate 10. An L-shaped assembly frame 13 is fixedly connected to the top of the heat dissipation frame 6. The assembly plate 12 and the L-shaped assembly frame 13 are slidably connected. Two symmetrically arranged springs 14 are fixedly connected to the top of the L-shaped assembly frame 13. A pull plate 15 is fixedly connected to the top of the two springs 14. Two symmetrically arranged locking pins 16 are fixedly connected to the bottom surface of the pull plate 15.

[0024] As an optional technical solution of this utility model, a slot 17 is provided on the side of the U-shaped frame 1 near the sealing plate 10. The card plate 11 is engaged with the U-shaped frame 1 through the slot 17, and the sealing plate 10 is engaged with the U-shaped frame 1 through the card plate 11, which can make the connection between the sealing plate 10 and the U-shaped frame 1 more secure.

[0025] The inner wall of the U-shaped frame 1 has two symmetrical T-shaped slides 18. Both T-shaped slide plates 8 are slidably connected to the U-shaped frame 1 through the T-shaped slides 18.

[0033] 3): Pull the pull plate 15 upward to make it move the locking pin 6 out of the locking hole 2, which can release the locking of the assembly plate 12. Then, remove the cover plate 9 and the sealing plate 10, and use bolts to install the U-shaped frame 1 inside the car charging pile, which can facilitate the installation of PCBA components.

[0034] In summary, after the circuit board 2 of the car charging pile PCBA assembly is processed, the operator can use bolts to lock the circuit board 2 inside the U-shaped frame 1. Then, two locking plates 5 are inserted into the inner walls of the two locking frames 3, and the locking plates 5 are locked using locking bolts 4. A wire is used to connect the cooling fan 7 to the circuit board 2, which can dissipate heat from the circuit board 2 during operation. Finally, the cover plate 9 is inserted into the U-shaped frame 1 along the T-shaped slide 18 until the cover plate 9 moves to the appropriate position. Then, the pull plate 15 is pulled to make the locking pin 16 engage with the assembly plate 12, thus locking the cover plate 9 onto the U-shaped frame 1. At this time, the sealing plate 10... By engaging the card plate 11 with the U-shaped frame 1, the connection between the sealing plate 10 and the U-shaped frame 1 can be made more secure.
