[0018] Furthermore, the grounding pile is fixedly connected to the connecting shell.
[0019] Furthermore, the upper portion of the grounding pile is a solid structure.
[0020] Furthermore, the height ratio between the upper part and the lower part of the grounding pile is 2:3.
[0021] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting the height ratio between the upper part and the lower part of the grounding pile to 2:3, the firmness of the grounding pile connected to the ground can be enhanced.
[0022] Compared with the prior art, the flexible graphite-based grounding connection device provided by the utility model has the following beneficial effects: by setting a contraction spring, the connection housing can be tightened by elastic force when the tension of the transmission line becomes smaller, so that the wire is tightened, so that the wire is collected inside the connection housing, thereby straightening the transmission line.

By setting the grounding pile to a five-pointed star structure, the grounding area of the grounding pile can be increased, which is conducive to enhancing the firmness of the connection between the grounding pile and the ground. By setting the material of the connection housing and the grounding pile to a flexible graphite-based material, the good conductivity, corrosion resistance, and high strength and toughness of the graphite-based material can be utilized, so that the connection housing and the grounding pile can withstand greater tension and pressure, and enhance the stability of use. By setting the lower part of the grounding pile to a concentric five-pointed star structure, the contact area between the grounding pile and the ground can be increased, which is conducive to enhancing the conductive efficiency of the grounding pile when necessary. By setting the height ratio of the upper part to the lower part of the grounding pile to 2:3, the firmness of the grounding pile connected to the ground can be enhanced. This can solve the problem that the tension of the transmission line decreases over time or due to pressure, causing the wires to become loose and overlapped, thereby affecting the transmission of electric energy and increasing the risk of electricity use.
