Polyimide has higher insulation performance and temperature tolerance, and is suitable for anti-electric shock insulation requirements in high temperature environments. Glass fiber reinforced plastic is a material made by compounding glass fiber with synthetic resin. Glass fiber reinforced plastic has good insulation properties, high strength and corrosion resistance, and is suitable for complex use environments.

[0028] The shell body 1 can be made of aluminum alloy, stainless steel, etc. The metal material has high strength and corrosion resistance, and can provide better shell protection. An electric shock protection plate 3 is used inside for insulation treatment to ensure the safe use of the charging pile.

[0029] The electric shock protection plate 3 includes two side panels 302 with U-shaped opening grooves 301, an upper connecting plate 303 connecting the two side panels 302, a lower connecting plate 304 and a rear connecting plate 305. The lower connecting plate 304 is provided with a lead hole 306 that cooperates with the insulating sheath 4 and penetrates through it. The lead hole 306 can be provided with a grounding device at the bottom of the shell body 1, including a grounding wire and a grounding pin, which is used to connect the metal part of the shell to the ground through the grounding wire to achieve electrostatic protection of the shell and personal safety protection.

[0030] The use of an anti-electric shock insulating shell can effectively isolate the internal circuit of the charging pile from the outside world, prevent current leakage and electric shock accidents, and ensure the personal safety of users. The addition of a protective outer cover 2 can effectively prevent the intrusion of external pollutants such as water and dust into the shell body 1, thereby improving the stability and reliability of the charging pile in harsh environments. The shell body 1 is composed of a rear cover plate 101, a front cover plate 102, an upper cover plate 103 and a lower cover plate 104.
