[0003] When installing existing chargers, generally, the shell is clamped by set hidden buckles. It is necessary to carefully align the shells and then clamp the hidden buckles one by one. When performing internal maintenance, it is necessary to pry open the hidden buckles to separate the shells. The hidden buckles are easily damaged, the operation is cumbersome and the durability is poor. At the same time, although the plug part of the existing charger can be rotated for storage, there is no clamping structure to fix it, which is more inconvenient to use. For this reason, we have proposed a charger circuit board shell. Content of the Utility Model

The slider 3 and the buckle 5 are provided. During installation, the slider 3 at the bottom of the top plate 2 is slid into the first chute 4, and then the cover plate 7 is covered on the side of the housing 1, so that the connecting rod 8 drives the clamping block 9 to be clamped into the buckle 5, and the installation of the charger housing 1 is completed. When internal maintenance is required, the cover plate 7 is pulled outwards to separate the buckle 5 and the clamping block 9, and then the top plate 2 is slid out from above the housing 1. The installation and disassembly are simple and have high durability. The washer 16 and the convex block 18 are provided. The plug 15 rotates through the rotating shaft 14 inside the cover plate 7. Washers 16 are provided on both sides of the plug 15. The washers 16 rub against the inner wall of the cavity inside the cover plate 7, and the frictional force fixes the angle of the plug 15. The plug 15 can be rotated 90 degrees to be stored. The second chute 17 provided on the surface of the plug 15 is composed of a card slot at the top and a guiding slot at the bottom. When the plug 15 rotates, the guiding slot contacts the convex block 18, and the convex block 18 slides in the guiding slot until it slides into the card slot and abuts against the card slot to fix the plug 15, reducing the possibility of the plug 15 shaking when the plug 15 is opened or stored, and it is more convenient to use.

[0024] Further, the size of the USB slot 6 matches that of the USB interface 13, and the USB interface 13 is plugged into the USB slot 6.

[0025] Further, the shape and size of the first chute 4 match those of the slider 3, and the slider 3 is slidably connected inside the first chute 4. The top plate 2 is movably connected to the top of the housing 1 through the cooperation of the first chute 4 and the slider 3.

[0026] Further, the clamping block 9 is clamped with the buckle 5. While the cover plate 7 is abutted against the side of the housing 1 through the cooperation of the clamping block 9 and the buckle 5, the connection between the top plate 2 and the housing 1 becomes more stable.

[0027] Further, four groups of positioning blocks 11 are circumferentially arranged on the surface of the fixing plate 10. The four groups of positioning blocks 11 are in contact with the four corners of the circuit board 12. The arrangement of the positioning blocks 11 makes the installation of the circuit board 12 more convenient.

[0028] Further, the plug 15 is sleeved on the surface of the rotating shaft 14. Two groups of washers 16 are fixedly connected to both sides of the plug 15. The washers 16 are sleeved on the surface of the rotating shaft 14. The washers 16 rub against the inner wall of the cavity inside the cover plate 7. The frictional force fixes the angle of the plug 15.

[0029] Further, the convex block 18 is spherical. A circular groove is formed on the inner wall of the cavity. The radius of the circular groove is greater than the radius of the convex block 18. The convex block 18 is rotatably connected in the circular groove. The second chute 17 consists of a card slot at the top and a guiding groove at the bottom. The convex block 18 matches the card slot. The depth of the guiding groove is less than the depth of the card slot. When the plug 15 rotates, the guiding groove contacts the convex block 18. The convex block 18 slides in the guiding groove until it slides into the card slot and abuts against the card slot to fix the plug 15.

[0030] Working principle: During installation, the slider 3 at the bottom of the top plate 2 is slid into the first chute 4, and then the cover plate 7 is covered on the side of the housing 1, so that the connecting rod 8 drives the clamping block 9 to be clamped into the buckle 5, completing the installation of the charger housing 1. When internal maintenance is required, the cover plate 7 is pulled outwards to separate the buckle 5 and the clamping block 9, and then the top plate 2 is slid out from above the housing 1. The four corners of the circuit board 12 are placed corresponding to the four groups of positioning blocks 11 and then fixed by bolts, making the installation of the circuit board 12 convenient. The plug 15 rotates through the rotating shaft 14 inside the cover plate 7. Washers 16 are arranged on both sides of the plug 15. The washers 16 rub against the inner wall of the cavity inside the cover plate 7. The frictional force fixes the angle of the plug 15. The plug 15 can be stored by rotating it 90 degrees. The second chute 17 provided on the surface of the plug 15 consists of a card slot at the top and a guiding groove at the bottom. When the plug 15 rotates, the guiding groove contacts the convex block 18. The convex block 18 slides in the guiding groove until it slides into the card slot and abuts against the card slot to fix the plug 15, reducing the possibility of the plug 15 shaking when the plug 15 is opened or stored.
