Abstract
The invention discloses a base of an annular common mode inductor. The base is characterized in that four steel needles are arranged on the base; and the sections of the steel needles are round; U-shaped grooves are formed in the side faces of the base, supporting boards are arranged between the base and a circuit board, and a cross baffle is arranged in the middle of the base. According to the base of the annular common mode inductor, production cost is saved, labor intensity is lowered, and labor productivity is improved.
Description
Technical field
The present invention relates to annular common mode inductance, particularly a kind of base of annular common mode inductance.
Background technology
Annular common mode inductance is typically used as common mode choke welding and plays the effect of control electromagnetic interference in the circuit board.Common mode inductance needs first to be positioned on base, then by four pin welding on circuit boards.Existing base is rectangular base plate, and base plate has four through holes more bigger than copper wire diameter, four pins being convenient to common mode inductance pass, and base plate has boss, has draw-in groove in boss, and draw-in groove runs through the upper bottom surface of base plate.Shell projection is inserted draw-in groove 13 by the common mode inductance after coiling completes, then by four pins through four through holes, makes it to become to be integrated with base.Such base, production technology normally coiling, fair line, decortication, tin sticky, by base, whole pin, cuts pin, test plate (panel), some glue, and each procedure is all essential, decortication and tin sticky high to labor claim.Decortication wants clean, puts in place, and tin sticky wants smooth without list edge, without leaking copper, four pins will be allowed through four through holes of base, and wanting whole pin, cut pin, test plate (panel) by base, ensure that product can weld on circuit boards fast securely.Each procedure is all wasted time and energy, and production efficiency cannot increase substantially.When each operation cannot round Realization automation, how to reduce operation and ensure that product quality will become boosting productivity, the unique channel saved production cost.
Summary of the invention
The object of the invention is to overcome the deficiency that above-mentioned existing production technology wastes time and energy, a kind of base of annular common mode inductance is provided, saves process portion, save production cost, reduce labour intensity, raise labour productivity.
For effectively solving the problems of the technologies described above, the technical scheme that the present invention takes is as follows: a kind of base of annular common mode inductance, is characterized in that: with four draw points on described base, and the cross section of draw point is circular; Base side has U-type groove, has supporting bracket between base and circuit board, has cruciform baffles agitated vessel in the middle of base.
Advantageous effect of the present invention is: be welded on four draw points of base by four pins of common mode inductance good for coiling, because the length of draw point, spacing all can be customized as requested, so just can save whole pin, cut pin, the operation of test plate (panel), some glue.And, the requirement of fair line, decortication, tin sticky operation is also reduced greatly.Base of the present invention, only needs pin end to peel, can be welded on draw point after ensureing tin sticky, not only time saving and energy saving, can also save material.And the material of draw point is stainless steel, stainless steel is not oxidizable in atmosphere.Therefore adopt annular common mode inductance of the present invention and base, eliminate process portion, reduce the difficulty requirement of required operation, saved production cost, improve production capacity.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail
As shown in Figure 1, Figure 2, Figure 3 shows, the base of the embodiment of the base of a kind of annular common mode inductance of the present invention, comprise base body 33, draw point 36, supporting bracket 35, baffle plate 31,34-boss, wherein, the one side shape that base body 33 is connected with common mode inductance is rectangle, and both sides, with supporting bracket 35, prevent the pad contact circuit plate of the pin of common mode inductance and draw point from forming short circuit.Baffle plate 32 is cross, prevents the pad of four draw points and pin from contacting with each other formation short circuit.The cross section of draw point 36 is circular, and its length, diameter and spacing can be arranged according to drawing requirement, and the diameter of usual draw point is identical with the diameter of copper cash, ensures that draw point can effectively weld on circuit boards.Boss 34 is positioned at base body 33 central part, and inside has draw-in groove, and the shell projection 27 for common mode inductance is combined with draw-in groove.The both sides of base body 33 have U-type groove 32, and the pin of common mode inductance is welded together by U-type groove 32 and draw point 36.
Adopt the base of annular common mode inductance of the present invention, common mode inductance is welded together by the U-type groove on base and draw point, namely eliminates some processes, saved work and material cost, again reduce the difficulty requirement of required operation, effectively improve the quality of production and production efficiency.
The foregoing is only better possible embodiments of the present invention, not limit the scope of the invention, all utilizations description of the present invention and the change of the equivalent structure done by accompanying drawing content, be all included in protection scope of the present invention.
