Abstract
The utility model discloses a framework for a choke ring. The framework comprises a top plate, a bottom plate, a left side plate and a right side plate, which are assembled into the frame, wherein the left end and the right end of the bottom plate are respectively arranged on the bottoms of the left side plate and the right side plate through pin shafts; and a guide groove is vertically formed in each of the inner side surfaces of the left side plate and the right side plate. The framework is simple in structure and reasonable in design. An iron core body is easily inserted into the framework under the action of the guide grooves, the phenomenon of displacement is not caused, the framework is convenient to assemble, and the using requirements of an enterprise 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 framework.
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, so with in its framework procedures of packing into, the phenomenon of dislocation takes place easily, be not easy to processing, production efficiency is low.
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 framework.
The utility model is realized through following technical scheme:
A kind of choke is used framework; Include the top board, base plate and the left and right side plate that are assembled into shaped as frame; The left and right two ends of said base plate are installed in the bottom of left and right side plate respectively through bearing pin, it is characterized in that: have vertical guide groove on the medial surface of said left and right side plate.
A kind of choke is used framework, it is characterized in that: the bottom of said left and right side plate is separately installed with the left and right supporting leg of mutual correspondence.
The side, both sides of the iron-core workpiece corresponding with the utility model framework is provided with convexity.During operation, pull down base plate earlier, iron-core workpiece is inserted from the bottom opening of the utility model, and said convexity is snapped in the corresponding guide groove, and the guide effect through guide groove, iron-core workpiece inserts in the framework.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, through the effect of guide groove, makes iron-core workpiece insert easily in the framework, inconsistent phenomenon can not take place, and is convenient to assembling, satisfied the user demand of enterprise.
Description of drawings:
Fig. 1 is the front view of the utility model.
Fig. 2 is the vertical view of the utility model.
Embodiment:
Referring to accompanying drawing.
A kind of choke is used framework; Include the top board 1, base plate 2 and the left and right side plate 3,4 that are assembled into shaped as frame; The left and right two ends of said base plate 2 are installed in the bottom of left and right side plate 3,4 respectively through bearing pin, have vertical guide groove 7 on the medial surface of left and right side plate 3,4.
The bottom of left and right side plate 3,4 is separately installed with the left and right supporting leg 5,6 of mutual correspondence.
