Zusammenfassung:The utility model relates to a contact finger type grounding contact, which comprises a contact finger spring, a grounding and bridging conductor and a grounding conductor, wherein the grounding and bridging conductor is in an annular shape, a V-shaped connecting groove is formed in the inner surface, the grounding and bridging conductor is connected with the contact finger spring reliably through the V-shaped connecting groove, the side surface of the grounding and bridging conductor is further provided with a connecting column head, a connecting screw hole is formed in the connecting column head, an arc-shaped positioning groove is formed in a position where the connecting column head is in contact with the upper surface of the grounding and bridging conductor, one end of the grounding conductor is connected with the grounding and bridging conductor through the connecting screw hole in the connecting column head of the grounding and bridging conductor, and a connecting screw hole is formed in the other end to be connected by an external grounding bar. When compared with a grounding contact structure used in a traditional solid insulated ring main unit, the contact finger type grounding contact has the advantages of good matched connecting performance of moving and static contacts, good stability, few abrasion loss and low contact surface resistivity, is not liable to loose, and is stable, thereby greatly solving the defects of a traditional grounding contact that the use abrasion loss is large, the connecting structure is liable to loss, the resistance is too high and the like.
