The invention provides a ground connector of a modified silicate composite material. The ground connector comprises an internal metal core and an external composite layer wrapping the internal metal core; the internal metal core axially penetrates the inside of the external composite layer, and the two ends of the internal metal core are exposed out of the external composite layer; and an anti-counterfeiting chip is embedded in the external composite layer to pre-store production information of the ground connector of the modified silicate composite material. In the ground connector of the composite material, the anti-counterfeiting chip is embedded in the external composite layer to store the production information of the ground connector, so that an external identifier can read the production information, authenticity of a product can be verified rapidly, performance information of the product can be extracted, interests of a manufacturer are protected effectively, and the safety problems in grounding operation caused by fake products can be reduced.
