Inductor and manufacturing method thereof

Abstract

The invention discloses an inductor and a manufacturing method thereof. The manufacturing method includes that one end of a magnetic core column is abutted against a first magnetic end cap, a coil with two connecting parts is sleeved with the magnetic core column, the two connecting parts are arranged in two opening holes, and then the first magnetic end cap covers the first end of a shell with an accommodation space, so that the magnetic core column and the coil can be accommodated in the accommodation space; magnetic powder is filled into the accommodation space to form a magnetic powder layer so as to cover the coil and the magnetic core column, and then a second magnetic end cap covers the second end of the shell and is abutted against the other end of the magnetic core column, so that the magnetic powder layer and the coil sleeved with the magnetic core column are sealed in the accommodation space, and the two connecting part are bent towards one side of the first magnetic end cap away from the shell. The magnetic core column and the first and second magnetic end caps can be manufactured by different materials, magnetic saturation characteristics of the inductor can be added, and manufacturing cost is reduced.

Description

technical field [0001] The present invention relates to an inductor and a manufacturing method thereof, in particular, to an inductor capable of reducing manufacturing costs and a manufacturing method thereof. Background technique [0002] Inductor is a kind of passive component, which has the functions of filtering and removing noise, suppressing instantaneous current, reducing EMI (Electromagnetic Interference, electromagnetic interference) and power conversion. It has been widely used in various electronic products for a long time. [0003] figure 1 It is a schematic diagram of an existing inductor. Firstly, an I-shaped core 11 is glued on the base 10, and then a wire is helically wound around the core 11 by a coil injection device to form a coil 12, and the helical part 121 is formed around On the core 11 , the wiring part 122 extends from both ends of the helical part 121 and is fixed on the base 10 . Finally, the shell 13 is assembled so that the core 11 and the coil ...

Problems solved by technology

[0004] However, figure 1 The inductor shown has many disadvantages in the manufacturing process, for example: the I-shaped core 11 is directly processed, and waste will be generated during the cutting process; secondly, the core 11 and the base 10 need to be bonded first The coil injection process can be carried out, and then the wiring part 122 is fixed on the base 10, which increases the production time; in addition, the combination of the shell 13, the core body 11 and the base 10 requires alignment technology, otherwise it is easy to cause electric shock.
