The utility model discloses a novel composite socket, relates to a wiring device of an electric system, and is used to solve problems that after multiple times of plug and insertion, impedance of contact surfaces of reeds is increased, voltage drop is increased, and the reeds are heated, and problems that the reeds are easy to deform after being used for a long period and the service life is short. The novel composite socket comprises branching sockets. Each branching socket comprises a front terminal, a rear terminal, a front copper pillar, a rear copper pillar, a jack and a base plate. The jack comprises front double reeds and rear double reeds. The front double reeds comprise an upper single reed and a lower single reed which are separated. The rear double reeds comprise an upper single reed and a lower single reed which are separated. Opposite surfaces of front ends of the upper single reeds of the front and rear double reeds are bent to form upper contact surfaces, and the front ends of the upper single reeds are conducted through the upper contact surfaces. Opposite surface of front ends of the lower single reeds of the front and rear double reeds are bent to form lower contact surfaces, and the front ends of the lower single reeds of the front and rear double reeds are conducted through the lower contact surfaces. Opposite ends of the front and lower copper pillars are provided with a spacing projection respectively. Due to improvement of the branching sockets, the reliable composite socket is improved.
