The invention discloses an anti-icing collector ring of a helicopter tail rotor. The anti-icing collector ring comprises a rotor (1), an outer cover (2) and an electric brush box (4). The rotor (1) isprovided with a base (101), conducting ring assemblies (102) is stacked on the columnar outer wall of the upper end of the base (101), a pressing plate (104) and a baffle plate (105) are arranged atthe upper end of the conducting ring assembly (102), and the conducting ring assemblies (102), the pressing plate (104) and the baffle plate (105) are fixed on the base (101) together; a cable (107) is led out of the lower end of the base (101), wires in the cable (107) are connected with the binding posts (106) on the conducting ring assemblies, and an end cover (108) is fixed to the lower end ofthe base (101); the electric brush box (4) is installed on one side of the outer cover (3), a sealing gasket (3) is arranged between the electric brush box and the outer cover, and the electric brushbox (4) can be replaced or maintained independently. The anti-icing collector ring is relatively simple in structure, good in maintainability, long in electric brush abrasion life and high in cable reliability.
