TECHNICAL FIELD

[0001] The utility model belongs to the through ground wire production and manufacturing equipment technical field, concretely relates to a through ground wire end fastener. BACKGROUND

[0002] With the rapid development of communication industry, cable is updated rapidly. The outer sheath of railway through ground wire requires to have the conductive function, and the update and replacement are particularly prominent. The outer sheath develops from the conductive material to the seam welded metal sheath, and the seam welded metal sheath develops to the seamless metal sheath, which leads to the high-speed development of equipment, production process and manufacturing method. Due to the high-speed development of production equipment, some corresponding supporting tooling molds develop slowly. The present application is a supporting tooling invention to fill the vacancy.

[0003] In the rolling production of seamless metal sheath railway through ground wire cable, the seamless metal sheath is rolled and reduced in diameter through dozens of rollers to make it in good contact with the cable core. In this rolling and reducing process, the metal sheath of seamless metal sheath railway through ground wire cable will produce very large metal internal stress, so that the seamless metal sheath railway through ground wire cable is as hard as steel. Due to the internal stress hardening of railway through ground wire cable during rolling, it is difficult to fix the end head when winding on the reel.

[0004] The method used at present is to bundle the through ground wire cable folded out of the edge of the winding reel on the side rib of the winding reel. This method has the problems of loose bundle and risk of injury, and the end head is wasted for a long time. INVENTION CONTENTS
