Abstract
The utility model discloses an iron core body for a choking coil, which comprises an I-shaped iron core body and an E-shaped iron core body of which a tongue body is cut off. Open positions of the I-shaped iron core body and the E-shaped iron core body are oppositely closed and are welded into one whole body by adopting argon arc welding. The iron core body for the choking coil has simple structure and reasonable design; small-size iron core sheets easy to process are overlaid and then are welded, so the iron core body is more convenient to manufacture, the yield is high and the using requirements of enterprises are met.
Description
Technical field:
The utility model relates generally to the choke technical field, relates in particular to a kind of choke and uses iron-core workpiece.
Background technology:
Anti-inductive coil of gripping alternating current.Utilize coil reactance and frequency proportional, can control high-frequency ac current, let low frequency and direct current pass through.According to the frequency height, adopt air-core, ferrite core, silicon steel label etc.Claim " smoothing choke " when being used for rectification; Claim " audio-frequency choke " when being used to control audio-frequency current; Claim " high frequency choke coil " when being used to control high-frequency current.The inductance coil that is used for " perfectly straight stream, resistance exchange " is called low-frequency choke coil, and the inductance coil that is used for " logical low frequency, resistance high frequency " is called high frequency choke coil.
The principle of coil chokes generically is exactly when electric current passes through, and the magnetic field that coil produces can hinder the magnetic field that electric current produces because of self-induction, thereby current slow is passed through." low-frequency choke " stops alternating current to pass through because of the time ratio alternating current that postpones changes the required time length of direction.The time that " high frequency choke coil " postpones changes the required time of direction less than low frequency ac but changes the required time of direction greater than high-frequency alternating current, thus low frequency ac can through and high-frequency alternating current can not pass through.
At present, have miniature choke on the market, because the iron-core workpiece size of miniature choke is less, be not easy to processing, percent defective is higher.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of choke of reasonable in design to use iron-core workpiece.
The utility model is realized through following technical scheme:
A kind of choke is used iron-core workpiece, it is characterized in that: include the E sections core body of I sections core body and excision tongue body, the opening of I sections core body and E sections core body is combined and adopts argon arc welding to be welded as a whole.
A kind of choke is used iron-core workpiece, it is characterized in that: I sections core body is to be formed by multi-disc I sections chip mutual superposition.
A kind of choke is used iron-core workpiece, it is characterized in that: E sections core body is that the E sections chip mutual superposition by a plurality of excision tongue pieces forms.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, and through welding again after the undersized lamination mutual superposition that will be easy to process, institute is so that the iron-core workpiece making is comparatively convenient, and rate of finished products is high, has satisfied the user demand of enterprise.
Description of drawings:
Fig. 1 is the front view of the utility model.
Fig. 2 is the left view of the utility model.
Embodiment:
Referring to accompanying drawing.
