[0002] In electrical engineering, the generation of current is inseparable from the PCB board. However, most general-purpose end caps currently use bolts or bushings and washers to ensure the position of the PCB board, which is troublesome to install and cannot guarantee accuracy. When installing the back cover, the back cover is prone to displacement due to the lack of limiters. Screwing requires holding it in place for alignment, resulting in low work efficiency. Utility Model Content

[0003] In view of this, this application provides a raised end cap structure, which is simple in structure and solves the problem of low working efficiency caused by the lack of limiters.

[0004] According to one aspect of this application, a raised end cap structure is provided for use with a PCB board, including a rear end cap and a rear cover, wherein the rear end cap and the rear cover are detachably connected, and the PCB board is fixed between the rear end cap and the rear cover; the rear cover is a plate-shaped structure with a preset thickness, and the connection end between the rear cover and the rear end cap is an open structure; the rear end cap is a plate-shaped structure with a preset thickness, and the connection end between the rear end cap and the rear cover is divided into an inner cylinder and a connecting part, wherein the inner cylinder is connected to the PCB board, the height of the inner cylinder is higher than the height of the connecting part, and a fixing block is provided at the top edge of the inner cylinder, the fixing block being adapted to the PCB board.

[0005] In one possible implementation, multiple fixing blocks are arranged around the edge of the connection end between the inner cylinder and the PCB board, and a first through hole is provided on the fixing block, the first through hole passing through both ends of the fixing block.

[0006] In one possible implementation, the fixing block is a semi-circular structure with a preset thickness, and the diameter of the semi-circular structure has a certain curvature, which matches the edge of the inner cylinder.

[0007] In one possible implementation, the diameter edge of the fixing block extends outward to form an extension portion, and a square groove is formed in the middle of the extension portion.

[0008] In one possible implementation, a second through hole is formed at the center of the inner cylinder, and a third through hole is formed at the edge of the inner cylinder; the second through hole is circular, the third through hole is rectangular, and both the second through hole and the third through hole penetrate both ends of the inner cylinder.

[0009] In one possible implementation, the opening structure at the connection end between the rear cover and the rear end cover is cylindrical, and the diameter of the opening structure is slightly larger than the diameter of the inner cylinder.

[0010] In one possible implementation, a fourth through hole is provided on one side of the rear cover. The fourth through hole has a rectangular structure, and one end of the fourth through hole passes through the connection end between the rear cover and the rear end cover. The position of the fourth through hole is on the same axis as the third through hole.

[0011] In one possible implementation, the connecting part is provided with a plurality of fifth through holes, and the rear cover is provided with a plurality of sixth through holes, and the positions of the fifth through holes and the sixth through holes correspond to each other, and the number of the fifth through holes and the sixth through holes is the same.

[0014] The beneficial effects of this utility model are as follows: By setting a rear end cover and a rear cover, the rear end cover and the rear cover are detachably connected. The PCB board is fixed between the rear end cover and the rear cover through the matching between the rear end cover and the rear cover. The rear cover is a plate-shaped structure with a preset thickness, and the connection end between the rear cover and the rear end cover is an open structure. This setting is to facilitate the connection between the rear end cover and the rear cover. The hollow structure of the rear cover is to accommodate the PCB board. The rear end cover is a plate-shaped structure with a preset thickness. The connection end between the rear end cover and the rear cover is divided into an inner cylinder and a connecting part. The inner cylinder is to be able to enter the hollow structure of the rear cover. The connecting part is to facilitate the connection and fixation with the rear cover. The inner cylinder is connected to the PCB board. The height of the inner cylinder is higher than the height of the connecting part. A fixing block is set on the top edge of the inner cylinder. The fixing block is adapted to the PCB board. This setting is to fix the PCB board on the rear end cover and prevent the PCB board from shifting on the rear end cover, which would cause the rear cover to not be aligned with the rear end cover. This setting facilitates the limitation of the PCB board during installation, making it easier for the rear end cover and the rear cover to be aligned, thereby improving the efficiency of screw fixing later.

[0023] Specifically, the raised end cap structure includes a rear end cap 100 and a rear cover 200. The rear end cap 100 and rear cover 200 are provided to fix the PCB board, so the rear end cap 100 and rear cover 200 are detachably connected.

In order to prevent the PCB board from shifting between the rear end cover 100 and the rear cover 200, a fixing block 130 is provided on the top edge of the inner cylinder 110. The fixing block 130 is adapted to the PCB board, and the PCB board is connected and fixed with the fixing block 130, so that the PCB board will not shift between the rear end cover 100 and the rear cover 200.

[0024] In one possible implementation, multiple fixing blocks 130 are arranged around the edge of the connection end between the inner cylinder 110 and the PCB board, and a first through hole is provided on the fixing block 130, which passes through both ends of the fixing block.

[0025] Specifically, such as Figure 1 As shown, since the PCB board is circular and the inner cylinder 110 is also circular, in order to make the fixing block 130 fit the PCB board and the inner cylinder 110, the fixing block 130 is set around the edge of the connection end between the inner cylinder 110 and the PCB board. In order to better fix the PCB board, multiple fixing blocks 130 are set, and a first through hole is opened on the fixing block 130. The PCB board is fixed on the fixing block 130 by bolts.

[0026] In one possible implementation, the fixing block 130 is a semi-circular structure with a preset thickness, and the diameter of the semi-circular structure has a certain curvature, which matches the edge of the inner cylinder 110.

[0027] Specifically, in order to achieve a better connection with the rear cover 200 and to make the connection between the rear cover 200 and the rear end cover 100 smooth and without jamming, the fixing block 130 is a semi-circular structure with a preset thickness and the diameter of the semi-circular structure has a certain curvature to match the edge of the inner cylinder 110, so that the outer edge formed by the fixing block 130 on the inner cylinder 110 is still circular.

[0028] In one possible implementation, the diameter edge of the fixing block 130 extends outward to form an extension 131, and a square groove is provided in the middle of the extension 131.

[0029] Specifically, in order to match the edge of the PCB board, the diameter edge of the fixing block 130 extends outward to form an extension 131, and a square groove is provided in the middle of the extension 131. The square groove is provided to prevent the PCB board from rotating on the inner cylinder 110.

[0030] In one possible implementation, a second through hole is provided at the center of the inner cylinder 110, and a third through hole is provided at the edge of the inner cylinder 110; the second through hole is circular and the third through hole is rectangular, and both the second and third through holes penetrate both ends of the inner cylinder 110.

[0031] Specifically, a second through hole is provided at the center of the inner cylinder 110 so that the external magnet can pass through the second through hole and connect to the PCB board. A third through hole is provided at the edge of the inner cylinder 110 so that the power supply wire of the external power supply can pass through the third through hole and connect to the PCB board. With this arrangement, a complete power supply system is formed.

[0032] In one possible implementation, the opening structure at the connection end between the rear cover 200 and the rear end cover 100 is cylindrical, and the diameter of the opening structure is slightly larger than the diameter of the inner cylinder 110.

[0033] Specifically, such as Figure 2 As shown, in order to enable the rear cover 200 to match and connect with the rear end cover 100, the opening structure of the rear cover 200 is also circular in shape.

[0034] In one possible implementation, a fourth through hole is provided on one side of the rear cover 200. The fourth through hole has a rectangular structure, and one end of the fourth through hole passes through the connection end between the rear cover 200 and the rear end cover 100.

[0035] In one possible implementation, the connecting part 120 is provided with a plurality of fifth through holes, and the rear cover 200 is provided with a plurality of sixth through holes, and the positions of the fifth through holes and the sixth through holes correspond to each other, and the number of the fifth through holes and the sixth through holes are the same.

[0037] In one possible implementation, a clearance hole is provided at the opposite end of the connection between the rear cover 200 and the rear end cover 100, and the position of the clearance hole corresponds to the position of the sixth through hole.

[0038] Specifically, such as Figure 2 As shown, clearance holes are provided at the opposite ends of the connection between the rear cover 200 and the rear end cover 100 to facilitate the tightening of screws by the staff.

[0039] In one possible implementation, recessed slots are provided on the four vertices of the rear cover and the back cover. This design makes the overall appearance more aesthetically pleasing and saves costs.

[0040] When using this application: the PCB board is fixed on the inner cylinder 110 by the fixing block 130, and the PCB board is limited by the square groove to prevent rotation. Then, the rear cover 200 and the rear end cover 100 are aligned, and the fixing block 110 also serves as a guide. Then, the PCB board is fixed between the rear end cover 100 and the rear cover 200 by the cooperation between the fifth through hole and the sixth through hole.

[0041] This application uses a rear end cover 100 and a rear cover 200. The matching of the rear end cover 100 and the rear cover 200 fixes the PCB board between them. A fixing block 130 on the inner cylinder 110 further secures the PCB board, and a square groove on the fixing block 130 prevents the PCB board from rotating on the inner cylinder 110. The engagement of the second, third, and fourth through holes allows the power supply wire and magnet of the external power source to contact the PCB board for power supply. The engagement of the fifth and sixth through holes further secures the rear end cover 100 and the rear cover 200. This design facilitates PCB board positioning during installation, ensuring alignment between the rear end cover and the rear cover, and improving the efficiency of subsequent screw fixing.
