Three-way branch joint for coaxial cable

The invention provides a three-way branch connector for a coaxial cable. The connector comprises a socket assembly and three plug assemblies. The socket assembly comprises an insulating main body, an outer conductor three-way fitting, an inner conductor three-way fitting and three socket flanges; each plug assembly comprises an inner conductor connecting unit, an outer conductor connecting unit and a plug unit which are connected in sequence. Three-way branching of inner and outer conductors of the coaxial cables is achieved through the socket assembly and the three plug assemblies, electric connection of the outer conductors of the three coaxial cables is achieved through the outer conductor three-way fitting, and electric connection of the inner conductors of the three coaxial cables is achieved through the inner conductor three-way fitting. Through the cooperation of the inner and outer conductor three-way fitting and the inner and outer conductor connecting unit, the efficiency of mounting and dismounting
