Terminal blocks used for PE electrofusion pipe fittings and PE electrofusion pipe fittings

The invention discloses terminal blocks used for PE electrofusion pipe fittings and PE electrofusion pipe fittings, and relates to polyethylene pipelines used for a buried pipelines. The terminal blocks is formed through adopting a copper alloy plate to punch, the terminal blocks comprises a hollow cylinder, a connecting section and a rectangular base, after the terminal blocks and a resistance wire are occlusion fastened, and then a whole part is injected into the bodies of the PE electrofusion pipe fittings. According to the terminal blocks used for the PE electrofusion pipe fittings and thePE electrofusion pipe fittings, the terminal blocks is formed through adopting a copper alloy plate to punch, the performance is guaranteed, at the same time, copper resources is greatly saved, the cost is reduced, the processing efficiency is improved; and the special hollow structure composed of the hollow cylinder, the connecting section and the rectangular base is adopted to occlusion fastenwith the resistance wire,
