Power connection structure and mining flame-proof feed switch

The utility model relates to the technical field of mining flame-proof switches, and particularly discloses a power connection structure and a mining flame-proof feed switch. The power connection structure comprises a wire inlet assembly, a wire outlet assembly and an isolation knife switch assembly, the wire inlet assembly comprises a wire inlet column and a static contact connected with the wire inlet column, the wire outlet assembly comprises a wire outlet column and a fixed head connected with the wire outlet column, and the isolation knife switch assembly comprises an isolation blade. One end of the isolation blade is hinged to the fixed head, and the other end of the isolation blade abuts against the static contact. The mining flame-proof feed switch has the effects of simplifying the structure and optimizing the layout, the complexity and uncertainty of the mining flame-proof feed switch can be reduced, the equipment failure rate is reduced, the maintenance is relatively convenient, and the overall cos
