[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model.

[0028] Embodiment 1:

[0029] Please refer to Figures 1-4 , the utility model provides a technical scheme:

[0030] A novel safe power-off grounding terminal, comprising a grounding terminal body 1, a bolt 3 and an insulation positioning piece 4, the grounding terminal body 1 is clamped with the insulation positioning piece 4 through a spring 2, so that the two are assembled well, the bolt 3 is passed through the grounding terminal body 1 and the insulation positioning piece 4 and presses down the spring 2, and meanwhile a double-wall heat shrink tube 5 is covered at the tail of the grounding terminal body 1, so that the external insulation effect is achieved.

[0031] As Figure 3 , 4 shown:

[0032] A positioning head is arranged at one side of the insulation positioning piece 4, convenient for positioning and marking, and a positioning hole 6 is formed at the center of the insulation positioning piece 4, convenient for the bolt 3 to pass through the positioning hole 6.

[0033] As Figure 1 shown:

[0034] The spring base 7 for mounting the spring 2 is mounted inside the insulating positioning member 4, which is convenient for connecting with the spring 1.

[0035] As Figure 3 , 4 shown:

[0036] The inner recess table 8 is arranged inside the insulating positioning member 4, and a hollow is arranged on the upper part for exposing the lower teeth 10 of the terminal, so as to connect the lower teeth 10 of the terminal with the body sheet metal, thereby achieving the effect of power supply.

[0037] Working principle:

[0038] The bonding terminal body 1 is clamped into the insulating positioning member 4 through the spring 2, the tail of the bonding terminal body 1 is crimped with the wire harness, and the tail of the bonding terminal body 1 is covered by the double-wall heat shrink tube 5 to achieve the effect of insulation with the outside.

[0039] When assembling, the lower teeth 10 of the terminal are connected with the body sheet metal by pressing the bonding terminal body 1 through the bolt 3 to compress the three springs 2 under the terminal, thereby achieving the effect of power supply.

[0040] When the bolt 3 is loosened, the lower teeth 10 on the bonding terminal body 1 are retracted into the insulating positioning member 4 through the elastic force of the spring 2, thereby achieving the effect of safe power-off.
