[0002] When performing withstand voltage tests on a charger, the grounding screw needs to be removed and installed. Currently, grounding screws are typically installed on a printed circuit board (PCB) inside the casing. Therefore, removing the grounding screw requires opening the charger's cover. Then, the grounding screw is removed from the PCB. During this operation, if not handled carefully, the grounding screw can easily fall off the PCB and into the casing. The internal structure of the charger casing is complex, making it very difficult to locate and remove the fallen grounding screw. Leaving the grounding screw inside the casing poses a significant risk to the charger's operation. Utility Model Content

Figures 6-9 The installation method of the isolation structure of this utility model and its positional relationship with related components are also shown. It should be noted that the charger contains many different components; in order not to obscure the inventive point of this invention and to facilitate understanding by those skilled in the art, [details omitted]. Figures 6-9 In this invention, other structures unrelated to the inventive point of this utility model are omitted.

[0030] The following is combined Figures 1-9 The isolation structure of this utility model is described in detail below. For example... Figures 1-5 ,as well as Figure 6 As shown, the isolation structure 100 of this utility model is designed as a conduit structure, which includes a mounting part 110 and a tubular part 120. The mounting part 110 is fixed on the cover plate 200, and the tubular part 120 is disposed on the mounting part 110 and extends toward the mounting structure 300 to form a channel 130 for accommodating disassembly and assembly instruments; the tubular part 120, the cover plate 200 and the mounting structure 300 together form a safe space for isolating the screw 400 to be disassembled to prevent it from falling.

[0031] In a preferred embodiment of this utility model, such as Figures 1-6As shown, the length of the tubular portion 120 extending toward the mounting structure 300 is equal to the distance between the cover plate 200 and the mounting structure 300. Thus, the tubular portion 120, the cover plate 200, and the mounting structure 300 together form a bottom-sealed safety space to isolate the screw 400 to be removed, preventing it from falling into, for example, a housing. Alternatively, in another preferred embodiment of this invention, the length of the tubular portion 120 extending toward the mounting structure 300 can be slightly less than the distance between the cover plate 200 and the mounting structure 300; that is, the distance between the bottom of the tubular portion 120 and the mounting structure 200 is less than the length of the screw to be removed. Therefore, a certain gap exists between the tubular portion 120 and the mounting structure 300, but this gap must be less than the length of the screw to be removed to prevent it from falling out of the mounting space.

[0032] In a preferred embodiment of this utility model, such as Figures 1-6 As shown, the mounting portion 110 is a racetrack-shaped mounting portion 110, and the tubular portion 120 has a circular cross-sectional shape. The tubular portion 120 is located at the center of the racetrack-shaped mounting portion 110. Of course, in other preferred embodiments of this utility model, any suitable shape of mounting portion can be used, such as rectangular or rhomboid. The tubular portion 120 can also be located at any suitable position on the mounting portion, and it can also be selected with any suitable cross-sectional shape, as long as it can ensure that the disassembly and assembly tools can pass through the channel 130 formed therein to disassemble the screw 400 to be disassembled.

[0033] Further as Figures 1-6 As shown, screw holes 111 are respectively provided on both sides of the racetrack-shaped mounting portion 110; screw holes 210 are provided on the cover plate 200 opposite to the screw holes 111. The racetrack-shaped mounting portion 110 is fixed to the cover plate 200 by mounting screws 220, screw holes 111, and screw holes 210. A mounting hole 230 is provided on the cover plate 200 opposite to the tubular portion 120 to allow the tubular portion 120 to extend through the cover plate 200. Preferably, self-tapping screws can be used for fixing. Preferably, the diameter of the mounting hole 230 matches the size and shape of the tubular portion 120. Of course, in other preferred embodiments of this utility model, a greater number of screw holes can be provided, for example, multiple screw holes can be provided around the racetrack-shaped mounting portion 110, or other similar screws can be selected; all of these fall within the protection scope of this utility model.

[0034] The tubular portion 120 further extends in a direction away from the mounting structure 300 to be slightly higher than the side 112 of the mounting portion 110 facing away from the mounting structure 300, thereby facilitating manufacturing. The screw to be removed 400 and / or the mounting screw hole of the screw to be removed 400 are located at the center of the tubular portion 120.

[0035] In a preferred embodiment of this utility model, the isolation structure is applicable to grounding screws, that is, the screw 400 to be disassembled is a grounding screw. Therefore, the mounting structure 300 is a printed circuit board, the mounting part 110 is a pressure-resistant insulating mounting part 110, and the tubular part 120 is a pressure-resistant insulating tubular part 120. Preferably, the mounting part 110 and the tubular part 120 are integrally formed.

[0036] The following is combined Figures 6-8 The principle of the isolation structure of this utility model is explained as follows. When screws need to be removed or installed, self-tapping screws can be used to install the racetrack-shaped mounting part of the isolation structure onto the cover plate 200. This allows the tubular part 120, the cover plate 200, and the mounting structure 300 to form a safe space for isolating the screws to be removed. This effectively isolates the screws and prevents them from falling into the machine housing during screw removal or installation, thereby improving work efficiency and safety.

[0037] The isolation structure of this utility model, by fixing the mounting part to the cover plate and extending a tubular part from the mounting part, forms a safe space together with the cover plate and the mounting structure to isolate the screw to be disassembled. This effectively isolates the screw to be disassembled, preventing it from falling into the machine housing during screw disassembly and assembly, thereby improving work efficiency and safety.

[0038] like Figures 6-9 As shown, a further preferred embodiment of this utility model discloses a charger, including a housing 500, a cover plate 200 for sealing the housing, a printed circuit board 300 (i.e., the aforementioned mounting structure) housed inside the housing 500, a grounding screw 400 (i.e., the aforementioned screw to be removed) mounted on the printed circuit board 300, and an isolation structure 100. Combined with... Figures 1-5 It is understood that the isolation structure 100 includes a mounting portion 110 and a tubular portion 120. The mounting portion 110 is fixed to the cover plate 200, and the tubular portion 120 is disposed on the mounting portion 110 and extends toward the printed circuit board 300 to form a channel 130 for accommodating disassembly and assembly equipment. The tubular portion 120, the cover plate 200, and the printed circuit board 300 together form a safety space for isolating the grounding screw 400 to prevent it from falling off.

[0039] like Figures 1-6As shown, the length of the tubular portion 120 extending toward the printed circuit board 300 is equal to the distance between the cover plate 200 and the printed circuit board 300. Thus, the tubular portion 120, the cover plate 200, and the printed circuit board 300 together form a bottom-sealed safety space to isolate the grounding screw 400 and prevent it from falling out. Of course, in another preferred embodiment of this invention, the length of the tubular portion 120 extending toward the printed circuit board 300 can also be slightly less than the distance between the cover plate 200 and the printed circuit board 300, that is, the distance between the bottom of the tubular portion 120 and the printed circuit board 200 is less than the length of the grounding screw 400. Therefore, there is a certain gap between the tubular portion 120 and the printed circuit board 300, but this gap must be less than the length of the grounding screw 400 to prevent the grounding screw 400 from falling out of this mounting space.

[0040] In a preferred embodiment of this utility model, such as Figures 1-6 As shown, the mounting portion 110 is a racetrack-shaped mounting portion 110, and the tubular portion 120 has a circular cross-sectional shape. The tubular portion 120 is located at the center of the racetrack-shaped mounting portion 110. Of course, in other preferred embodiments of this utility model, any suitable shape of mounting portion can be used, such as rectangular or rhomboid. The tubular portion 120 can also be located at any suitable position on the mounting portion, and it can also be selected with any suitable cross-sectional shape, as long as it can ensure that the disassembly and assembly tools can pass through the channel 130 formed therein to disassemble the grounding screw 400.

[0041] Further as Figures 1-6 As shown, screw holes 111 are respectively provided on both sides of the racetrack-shaped mounting portion 110; screw holes 210 are provided on the cover plate 200 opposite to the screw holes 111. The racetrack-shaped mounting portion 110 is fixed to the cover plate 200 by mounting screws 220, screw holes 111, and screw holes 210. A mounting hole 230 is provided on the cover plate 200 opposite to the tubular portion 120 to allow the tubular portion 120 to extend through the cover plate 200. Preferably, self-tapping screws can be used for fixing. Of course, in other preferred embodiments of this utility model, a greater number of screw holes can be provided, for example, multiple screw holes can be provided around the racetrack-shaped mounting portion 110, or other similar screws can be selected; all of these fall within the protection scope of this utility model.

[0042] The tubular portion 120 further extends in a direction away from the printed circuit board 300 to be slightly higher than the side 112 of the mounting portion 110 facing away from the printed circuit board 300, thereby facilitating manufacturing. The grounding screw 400 and / or the mounting screw hole of the grounding screw 400 are located at the center of the tubular portion 120.

[0043] In a preferred embodiment of this utility model, the tubular portion 120 is a pressure-resistant insulating tubular portion 120. Preferably, the mounting portion 110 and the tubular portion 120 are integrally formed.

[0044] The following is combined Figures 6-8 The principle of the charger of this utility model is explained as follows. When screw removal and installation are required, the racetrack-shaped mounting part of the isolation structure can be first installed onto the cover plate 200 using self-tapping screws, and then the cover plate 200 can be installed onto the housing 500. The tubular part 120, the cover plate 200, and the printed circuit board 300 together form a safe space for isolating the grounding screw 400 from other components inside the housing, thereby preventing it from falling into the housing. When removing or installing the grounding screw 400 on the printed circuit board 300, it is not necessary to remove the cover plate 200, and the grounding screw 400 can be prevented from falling into the housing.

[0045] Although this utility model has been described through specific embodiments, those skilled in the art should understand that various modifications and equivalent substitutions can be made to this utility model without departing from its scope. Furthermore, various modifications can be made to this utility model for specific situations or materials without departing from its scope. Therefore, this utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of this utility model.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
