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.
Utility model content
The purpose of the utility model is to provide a kind of chip inductor, this chip inductor has quality stability good
Feature.
The technical solution of the utility model includes: a kind of chip inductor, including drum workpiece, on the both ends of drum workpiece are respectively
Magnetic conduction sheet and lower magnetic conduction sheet, middle part are magnet-wire column, the surface wrap coil of magnet-wire column, and the both ends of coiling are equipped with pin, under lead
Magnetic sheet is connect with ceramic wafer, and the two sides of ceramic wafer are fixedly connected with electrode A and electrode B respectively, is provided in electrode A and electrode B
Pin 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.
The utility model has the beneficial effects that compared with prior art, the scientific structure design of the utility model is reasonable, use
Pin weld part is set in pin slot by safe ready by the way that pin slot is arranged on the electrode, is conducive to fixed pin, no
It is easily mobile；Simultaneously when welding, scolding tin is full of pin slot, the appearance of obtained solder joint answer smooth, cleaning, uniformly, it is symmetrical, neat,
It is beautiful；It is less prone to rosin joint, dry joint phenomenon, stablizes the function of chip inductor, quality is stablized.The surface of electrode is embedded with antistatic
Grain, mentions the antistatic effect of chip inductor, stabilized product quality.Therefore, which has the function of stablizing chip inductor,
The good feature of quality stability.
