Description
Technical field
This utility model relates to magnetoelectricity technical field, particularly relates to a kind of PQ type differential mode inductors.
Background technology
Inductance is an attribute of closed-loop path, i.e. when being changed by the electric current of closed-loop path, it may appear that electromotive force comes
The change of opposing electric current.Inductance has inhibition to alternating current.Differential mode inductance has to flow through alternating current power supply electric current, differential mode electricity
Feeling in the case of ac frequency is certain, inductance value is the biggest, and the biggest to the obstruction ability of alternating current, inductance value is the least, its resistance
Hinder ability the least.Separately, in the case of inductance value is certain, the frequency of alternating current is the highest, and inductance is to the obstruction ability of alternating current also
The biggest, frequency is the lowest, and inductance is the least to the obstruction ability of alternating current.It is to say, inductance have prevention alternating current by and allow straight
The characteristic that stream electricity passes through.Differential mode inductance is unidirectional, and differential mode is that a winding is individually connected on the filter inductance on zero line and live wire
Device can only filter differential mode interference or decay differential mode interference, and such as the spike of switching tube, the spike inducer of rectifier tube is special using
Component at the existing inductance of circuit interior-excess.
Current differential mode inductors due to be multi cord and around, in winding process, it is difficult to by multiply circular copper wire enamel-covered wire
Smooth around entering on bakelite skeleton, cause wire winding complicated；Second, due to relatively thin after bakelite skeleton wall everywhere, cause bakelite bone
Frame is easily broken, and both have impact on production, has added again production cost；3rd, the buttock line head that rises of the round copper enamel-covered wire of extraction is wound around
When the stitch of skeleton, because skeleton stitch is less, it is easily caused the crooked displacement of needle gage, reduces yield rate, simultaneously as play buttock line
Head twines contact easily higher than skeletal support salient point, meeting run-off the straight when causing downstream product electronic devices and components to insert circuit board,
Can not smooth circuit board so that electronic component products can rupture when transport, drop phenomenon, have impact on company reputation and
Image；4th, owing to magnetic core is relatively big, cause that small product size is big, quality weight, downstream product is difficult to miniaturization, miniaturization, also
Do not meet the developing direction of electronic product.
Being based on above-mentioned consideration, this utility model devises a kind of PQ type differential mode inductors, and small product size is little, quality
Gently, power is big, performance is excellent, easily realizes miniaturization, miniaturization, also complies with the developing direction of electronic product.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
See Fig. 1-Fig. 3.
The utility model discloses a kind of PQ type differential mode inductors, including the window in the middle part of magnetic core 1, coil 2 and coil 2
21 form magnetic core passages, it is characterised in that: described magnetic core 1 includes first magnetic core the 11, second magnetic core 12 being arranged in pairs, described the
One, being formed with magnetic core stem stem 13 in the middle part of the second magnetic core, described magnetic core stem stem 13 docks after magnetic core passage, and this case is by the
One, the magnetic core stem stem 13 in the middle part of the second magnetic core is threaded through coil winding machine and docks formation after the magnetic core passage of the coil 2 made, around
Wiring technology is simple, solve line footpath excessive can not the difficult problem of coiling, meanwhile, reduce the labor intensity of workman, improve production
Efficiency.
Described coil 2 is formed by a wire coiling, and wire winding is simple, reduces production cost.
Described wire is flat copper wire, and described flat copper wire is enamel-covered wire, exists relative to the advantage of traditional circular copper cash
In limited in linear distance, change the shape of line, can be many around about about 3 times than the general circular copper cash number of turn, thus promote
Overall inductance value, and be conducive to preferably heat radiation, the copper cash of same sectional area, area of dissipation is significantly increased, additionally by
The number of plies can be reduced in the number of turn more identical than original product, therefore can reduce parasitic capacitance value, product anti-electromagnetism is greatly improved and does
Immunity energy.
