The present invention provides a coupling-type new energy electric vehicle charging pile cable and double-layer co-extrusion segmented foaming equipment for preparing the coupling-type new energy electric vehicle charging pile cable. The coupling-type new energy electric vehicle charging pile cable includes Functional wire core, inner sheath and outer sheath, the functional wire core is wrapped in the inner sheath, the inner sheath is wrapped in the outer sheath, the outer sheath is made of foamed elastomer material, and The outer sheath is heated and foamed in sections to form a coupled structure. The electric vehicle charging pile cable of the present invention forms a coupling chain pile structure, which improves the extrusion resistance and bending resistance performance of the cable.
Description
technical field [0001] The invention belongs to the technical field of electric vehicle charging cables, and in particular relates to a coupling-type new energy electric vehicle charging pile cable and double-layer co-extruded segmented foaming equipment. Background technique [0002] With the development of society, the global energy crisis is intensifying, oil resources are becoming increasingly depleted, air pollution and global warming are becoming more and more serious, and cars, as an indispensable means of transportation for people to travel, are usually driven by burning oil, which will aggravate energy and the environment. crisis. In this regard, the automobile industry has launched new energy electric vehicles, which can avoid or reduce oil burning, which is conducive to promoting environmental protection and alleviating the shortage crisis of traditional energy sources, and has broad market development prospects. [0003] As an indispensable charging accessory fo...
