Abstract

The invention discloses a square closed magnetic circuit chip inductor which comprises a base. The base comprises a plastic substrate or a left copper conducting piece and a right copper conducting piece which are in central symmetry. A plurality of bosses and a plurality of wire hanging hooks are arranged on the base. Magnetic cores are arranged at the inner diameters of the bosses. Magnetic covers are arranged on the outer diameters of the bosses. Locating grooves are formed in the bottom ends of the side walls of the magnetic covers. Substrate connecting, winding, tin soldering, dispensing, assembling, post-processing printing, and testing or packaging are carried out, winding, tin soldering and assembling are mainly carried out, full automation is achieved, the structure is reasonable, the full-automatic winding technology of various wire diameters can be achieved, machining cost is greatly lowered, the bosses are designed on the plastic substrate or the left copper conducting piece or the right copper conducting piece, the stability of electricity is guaranteed, the magnetic cores are located on the inner diameters, the magnetic covers are located on the outer diameters, the success rate of automatic assembling is greatly improved, the temperature resistance degree is greatly improved, and the adhesive force of the copper conducting pieces and the magnetic cores is greatly improved.

Description

technical field [0001] The invention relates to a chip inductor, in particular to a square closed magnetic circuit chip inductor with reasonable structure, stable and safe. Background technique [0002] Chinese patent application number: 200910189837.4, discloses an inductor, especially relates to an inductor capable of withstanding relatively large current and having good electrical characteristics and a manufacturing method thereof. It includes a magnetic core, on which an enameled wire is wound, and the enameled wire is conductively connected with a welding pad or a lead pin, and the outer side of the magnetic core is filled with a magnetic powder resin mixture. The manufacturing method described above can be applied to chip inductors as well as plug-in inductors. [0003] Chinese patent application number: 201220371044.1, discloses a chip inductor, including a ring-shaped ferrite and a copper enameled coil, the thickness of the ring-shaped ferrite is 1-2mm, the inner di...
