[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a circuit board grounding protection structure, comprising:

[0025] A base 100, on which are provided dispersed grounding points 101;

[0026] A circuit board 200 is provided with a grounding hole 201 corresponding to the grounding point 101, and the grounding point 101 is firmly connected to the grounding hole 201; and,

[0027] The housing 300 is detachably connected to the base 100 .

[0028] In this embodiment, the grounding holes of the circuit board are screwed tightly together in a decentralized grounding manner, and the outer shell is tightly connected to the battery rack through the mounting holes. No separate external grounding wire is required, so that reliable grounding of the product can be achieved, the grounding wire of the printed circuit board is saved, the number of assembly workers is reduced, and the cost is reduced.

[0029] In one embodiment, see Figure 2 There are four grounding points 101 , which are dispersedly arranged at the four corners of the base 100 .

[0030] In one embodiment, see Figure 1 The housing 300 is provided with an anti-slip structure 400 for reinforcing the external wire connected to the circuit board 200. In this embodiment, the anti-slip structure 400 can improve the stability of the external wire connected to the circuit board 200, avoid the problem of loosening due to a little external force during use, and improve safety and stability.

[0031] In one embodiment, see Figure 4 The anti-drop structure 400 includes a slide groove 401 opened on the housing 300 , and a movable wire clamp 402 is provided in the slide groove 401 for clamping an external wire connected to the circuit board 200 .

[0032] This embodiment is configured such that after the external wire is connected to the circuit board 200, the wire clamp 402 is moved along the slide groove 401 toward and abuts against the external wire to fix the external wire so that the connection portion forms a whole with the housing 300, thereby ensuring the stability of the external wire connection.

[0033] In one embodiment, see Figure 4 The wire clamp 402 is provided with an active buckle 403 , and the slide groove 401 is provided with a positioning groove 404 that cooperates with the active buckle 403 .

[0034] This embodiment is configured such that after the wire clamp 402 is connected and fixed to the external wire, the movable buckle 403 is rotated to connect it with the positioning groove 404, so that the position of the wire clamp 402 is fixed, avoiding the problem of the wire clamp 402 being easily loosened, thereby ensuring the stable connection of the external wire.

[0035] In one embodiment, see Figure 5 A positioning rod 405 is provided in the slide groove 401 , and the positioning rod 405 is threadedly connected to the slide groove 401 .

[0036] This embodiment is configured to provide a second implementation method for positioning the wire clamp 402. When the wire clamp 402 is moved to connect with an external wire, the wire clamp 402 is driven to move by screwing the positioning rod 405. When the wire clamp 402 is moved into place to fix the external wire, the wire clamp 402 can be fixed by using a threaded limiter, thereby preventing the wire clamp 402 from easily loosening, thereby ensuring the stable connection of the external wire.

[0037] In one embodiment, the wire clamp 402 includes two wire clamping blocks, both of which are slidably disposed in the sliding groove, and the two wire clamping blocks are mutually clamped when assembled, and a groove is formed on the wire clamping blocks.

[0038] This embodiment is configured such that, after the external wire is connected to the circuit board 200, the two wire clamping blocks are driven to approach the external wire until they are assembled together and locked in place with each other, thereby stably fixing the external wire.

[0039] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.
