Surface closed double-layer isolation glue-free environmental-friendly wire coil

Abstract

The invention relates to a wire coil, and in particular to a surface closed double-layer isolation glue-free environmental-friendly wire coil. The wire coil comprises a wire coil base, an upper layer of coil, a lower layer of coil, a magnetic strip, a wire clamping frame and a magnetic strip cover. The wire coil base, the wire clamping frame, the coils and the magnetic strip are all ingeniously fixed through the magnetic strip cover, a conventional coil gluing and magnetic strip gluing mode is changed, a gluing technology is dispensed technologically, glue is not used, so that the wire coil is more environmental-friendly, moreover, the coils between laminations are isolated from each other through the wire clamping frame, so that the laminations can be effectively prevented from generating short circuit, and the wire coil is simple and compact in structure, and is convenient to install; and the magnetic strip adopts a triple-section type magnetic strip and is fixed through only one step, the magnetic strip of a scrapped wire coil can be directly dismantled for recycle, so that the production efficiency is increased, and the production cost is lowered.

Description

technical field [0001] The invention relates to a wire reel, in particular to a surface-closed double-layer isolation glue-free environmental protection wire reel. Background technique [0002] The wire reel is the basic component of the induction cooker, and the structural design of the wire reel has always been the focus of product development for the induction cooker manufacturer. At present, the reels are mainly divided into densely wound reels and sparsely wound reels. Although sparsely wound reels can reduce the difficulty of the reel process and solve the problem of inter-turn short-circuit in the X-axis horizontal direction of densely-wound reels, the existing sparsely wound reels still cannot solve the short-circuit problem between the two-layer coils in the Y-axis longitudinal direction, and Part of the existing sparse winding coils is fixed by glue coating, which is not environmentally friendly, and the process is very complicated. Contents of the invention ...
