Description
Technical field
The present invention relates to a kind of inductance, and in particular to a kind of chip inductor.
Background technique
Chip inductor is also known as power inductance, heavy-current inductor and surface mount high power inductance, has miniaturization, Gao Pin
The characteristics such as matter, high energy storage and low resistance, the inductance in general electronic circuit is air core coil, or the coil with magnetic core,
Lower voltage can only be born by lesser electric current, and power inductance also has air core coil, also has with magnetic core, mainly
Feature is to use heavy gauge wire coiling, can bear tens of peaces, hundreds of, thousands of, even tens of thousands of peaces, and power chip inductor is a point band magnetic cover
With without two kinds of magnetic cover, mainly it is made of magnetic core and copper wire, it is main in circuit to play filtering and oscillation action.Currently on the market
It is all mostly that soldering connection is carried out by manual welding mode between the pin and electrode of SMT Inductor, while SMT Inductor
Pin weld part directly contacted with electrode surface, since the welding technique of every employee, welding qualification are different, weld matter
Amount is also different, often will appear rosin joint and dry joint phenomenon, causes product quality hidden danger.Therefore, existing SMT Inductor draws
The shortcomings that foot is welded there are rosin joint and dry joint phenomenon, influence component function, causes product quality hidden danger.
Summary of the invention
The object of the present invention is to provide a kind of chip inductor, this chip inductor has the characteristics that quality stability is good.
Technical solution of the present invention: a kind of chip inductor, including drum workpiece, the both ends of drum workpiece are respectively upper magnetic conduction
Piece and lower magnetic conduction sheet, middle part are magnet-wire column, and the both ends of the surface wrap coil of magnet-wire column, coiling are equipped with pin, lower magnetic conduction sheet
It is connect with ceramic wafer, the two sides of ceramic wafer are fixedly connected with electrode A and electrode B respectively, are provided with pin in electrode A and electrode B
Slot.
One end of chip inductor above-mentioned, the coil is connect with electrode A soldering, and the other end is connect with electrode B soldering.
Chip inductor above-mentioned, the weld part of the pin are set in pin slot.
The surface of chip inductor above-mentioned, the electrode A and electrode B is embedded with antistatic particle.
Beneficial effects of the present invention: compared with prior art, scientific structure design of the invention is reasonable, uses secure side
Just, by the way that pin slot is arranged on the electrode, pin weld part is set in pin slot, is conducive to fixed pin, it is not easily shifted;
When welding simultaneously, for scolding tin full of pin slot, the appearance of obtained solder joint answers smooth, cleaning, uniform, symmetrical, neat, beauty;No
Easily there is rosin joint, dry joint phenomenon, stablize the function of chip inductor, quality is stablized.The surface of electrode is embedded with antistatic particle, proposes patch
The antistatic effect of piece inductance, stabilized product quality.Therefore, which has the function of stablizing chip inductor, and quality is steady
Qualitative good feature.
