Description

Three-in-one paster inductor

[ technical field ] A method for producing a semiconductor device

The utility model relates to an inductor technical field especially relates to a trinity paster inductor.

[ background of the invention ]

Inductance, a property of a closed loop, is a physical quantity. When the coil passes through the current, magnetic field induction is formed in the coil, and the induced magnetic field can generate induction current to resist the current passing through the coil. The interaction relation between the current and the coil is called as electric inductive reactance, and the small inductor in the market mainly adopts a color ring inductor (EMC) of a horizontal contact pin type and an I-shaped inductor vertical type and power type CD inductor patch type according to the using environment, action and power. The plug-in products are difficult to automate, so that the cost is increased, the line breakage of the color ring inductor due to the mechanical stress is a difficult problem which is difficult to solve for a long time, the customer complaints frequently occur, and the trust of companies is reduced. The CD inductor can basically realize automatic production, but the cost is difficult to reduce due to different materials, processes and structures, and the market competitiveness is lacked.

[ Utility model ] content

The utility model aims to solve the difficult problem of production technology broken string and reduce manufacturing cost, increase market competition not enough and a neotype trinity paster inductor that provides.

The utility model discloses a realize through following technical scheme:

the utility model provides a trinity paster inductor, includes the magnetic core body, be equipped with the wire casing in the middle of the magnetic core body, magnetic core body bottom both sides all extend there are first subsides dress seat and second subsides dress seat, first subsides dress seat is equipped with the first lead wire groove of perpendicular form, second subsides dress seat is equipped with the second lead wire groove of perpendicular form, draws first lead wire groove and twines on first lead wire groove again behind the enameled wire one end winding wire groove, forms first pin, draws second lead wire groove and twines on the second lead wire groove again behind the enameled wire other end winding wire groove, forms the second pin.

Furthermore, the solder on the bottom of the first pin is a first pin pad, and the solder on the bottom of the second pin is a second pin pad.

Furthermore, the magnetic core body is made of a high-frequency high-power current-resistant nickel-zinc material.

The beneficial effects of the utility model reside in that:

(1) the structure is simple, the design is reasonable, the automation is easy, and the compatibility is good; the enameled wire is wound on the lead slot, so that the wire breakage caused by mechanical tension is eliminated;

(2) the pollution of noble metal silver and electroplating to the environment is eliminated by the change of the structure.
