The invention discloses a large-current manual maintenance switch with a novel elastic piece
assembly structure, and belongs to the technical field of connectors. The switch comprises a plug, a socket, a conductive
copper bar which is arranged in the socket and is integrally punched and formed, a pressing
rivet nut fixed on the
copper bar, and a double-elastic-
sheet structure which is pressed and riveted on the
copper bar, through the integrated
stamping structure, the production process is simplified, and the cost is greatly reduced; the
mechanical reliability and the anti-vibration capability of connection are remarkably improved through the application of the pressing
rivet nut; due to the optimized conductive path and the double-elastic-sheet contact design, low temperature rise and stable
electrical connection are ensured when a large current passes through; according to the invention, the problems of high cost, poor connection reliability, high temperature rise and the like when an existing manual maintenance switch is used for coping with a high-
voltage platform of 1000V and above are effectively solved, and the manual maintenance switch is suitable for a high-
voltage power supply
system of a next-generation electric automobile.
