The utility model discloses a low-voltage bus duct connector. The low-voltage bus duct connector comprises a pressure groove plate and a connecting plate, an isolation bulge is arranged in the middleof one side of the groove pressing plate, and two ends are inwards-contracted inclined planes; the pressing groove plates are oppositely arranged with the isolation convex sides and hinged to the lower portion of the connecting plate, and a bus duct inserting cavity is defined between every two adjacent pressing groove plates. When the bus duct is used, the bus duct is inserted into the bus duct plugging cavity; the two ends of the groove pressing plate are both inwards-contracted inclined planes; that is, the outer opening of the bus duct plugging cavity is small. When the bus duct is inserted, the groove pressing plate can rotate around the hinge shaft until the inner end surface is flush with the bus duct; therefore, surface contact is realized, the through-current capability is improved, the contact tightness can be improved, the operation stability in the use process is ensured, good and stable contact between the coupler and the bus duct is ensured, and the situation of power failure of a user or burning loss of household appliances due to poor contact is avoided.
