[0005] In a preferred embodiment of the present invention, the grounding terminal can be further configured as follows: the grounding terminal is an elastic bending body, the upper bending body is in contact with the main shaft, and the lower bending body is in contact with the plastic bearing.

[0006] In a preferred embodiment, the present invention can be further configured as follows: upward-raised puncture check spikes are provided on both sides of the upper bending body, and a downward-raised buckle is provided in the lower bending body. The buckle is placed in a cavity near the side wall in the plastic bearing and is abutted against the inner wall through the buckle.

[0007] In a preferred embodiment of the present invention, the top of the raised end of the puncture-stop spike is pointed, and the pointed end faces outwards.

[0008] In a preferred embodiment of the present invention, the plastic bearings can be further configured as follows: the plastic bearings are divided into two groups that are not connected to each other, and are respectively clamped to the upper and lower surfaces of the main shaft.

[0009] Beneficial effect: A new photovoltaic grounding terminal structure of the utility model is designed to be a snap-on type. A small slot is reserved on the main shaft bearing. The snap-on grounding terminal is inserted into the slot, so that the terminal can be tightly fitted to the main shaft. On the one hand, the grounding operation can be performed, and on the other hand, the terminal can be prevented from retreating when vibrated. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1-4 As shown, a new photovoltaic grounding terminal structure includes a mounting base 2, a fixing hoop 4 for fixing the main shaft 1 is provided on the mounting base 2, a non-conductive plastic bearing 3 is provided between the fixing hoop 4 and the main shaft 1, a grounding terminal 5 is provided on the plastic bearing 3, one end of the grounding terminal 5 is in contact with the main shaft 1, and the other end is in contact with the mounting base 2 through a lead, the grounding terminal 5 is an elastic bending body, the upper bending body is in contact with the main shaft 1, and the lower bending body is in contact with the plastic bearing 3, the upper bending body is provided with upward-raised puncture check spikes 6 on both sides, and the lower bending body is provided with a downward-raised buckle 7 The buckle 7 is placed in the cavity near the side wall of the plastic bearing 3, and is against the inner wall through the buckle 7. The top of the raised end of the piercing non-return spike 6 is pointed, and the pointed angle is facing outward. During installation, the grounding terminal 5 is inserted into the opening reserved in the plastic bearing 3. Because the terminal is an elastic bending body, the bending body will be tightly attached to the main shaft 1, and the sharp end of the piercing non-return spike 6 will pierce the oxide layer on the surface of the main shaft 1, so that electricity can be smoothly conducted and the grounding terminal 5 can be prevented from retreating during vibration. The end of the lower bending body is against the inner wall of the plastic bearing 3 to prevent large external force pulling.

[0018] The plastic bearings 3 are divided into two groups that are not connected to each other, and are respectively clamped on the upper and lower surfaces of the main shaft 1, so as to be adaptable to main shafts 1 of various specifications.
