Abstract
The invention discloses a circular closed magnetic circuit chip inductor which comprises a base. One pair of opposite corners of the base is respectively provided with a wire hanging hook, and an annular boss is arranged in the middle of the base. The inner side of the annular boss is provided with a magnetic core, and the outer side of the annular boss is provided with a magnetic cover. Each wire hanging hook comprises a conduction piece, and the middle of each conduction piece is punched upwards to form a hook body. According to the circular closed magnetic circuit chip inductor, through base connecting, wire winding, tin soldering, dispensing and assembling and then printing processing or testing or packaging, complete automation is achieved mainly according to wire winding, tin soldering and assembling. The full-automatic wire winding technology of different wire diameters can be achieved, machining cost is greatly reduced, the stability of the electric property is ensured due to the boss designed on the plastic rubber base, the inner diameter is used for positioning the magnetic core, the outer diameter is used for positioning the magnetic cover, the size of the formed plastic rubber boss can reach the precision within 0.05, the success rate of automatic assembling is greatly improved, and the electrical characteristic of a product can be controlled quite stably due to the design of the magnetic cover.
