Abstract
A kind of filter inductance, it comprises base, magnet ring, four windings and eight capillaries, eight described capillaries divide two rows to be arranged on below base, magnet ring is arranged on above base, one end of four windings is respectively on corresponding four capillaries being welded on a wherein row, is welded on four capillaries corresponding to another row after the other end of four windings all walks around magnet ring.This inductance is because base needle gage is long, and be welded on printed board pad, pad diameter is 2.5mm, and the creepage distance in printed board also has 5mm, withstand voltage up to 4KV between group.Because be four windings, be particularly suitable for three-phase four-wire system power supply input filter.Because array pitch is wide, this inductance magnet ring used is also long, so performance also improves.
Description
Technical field
The utility model relates to inductance, especially has the filter inductance of new structure.
Background technology
Inductor can be the element that magnetic energy stores electric energy conversion.The similar of inductor in transformer, but only has a winding.Inductor has certain inductance, and it only hinders the change of electric current.If inductor is under the state not having electric current to pass through, during circuit ON, it will attempt to hinder electric current to flow through it; If inductor is under the state having electric current to pass through, circuit disconnect time it will attempt maintenance electric current constant.Inductor is also known as choke, reactor, dynamically reactor.
Traditional inductance needle gage is 6mm, and array pitch is 15 mm, 5 assembly welding pins, if this inductance is welded on the pad of printed board, this pad external diameter at least 2.5mm, the creepage distance between such two windings in printed board can only be 3.5mm, not withstand voltage between group.The power supply input of three-phase four-wire system, as long as four windings, so just waste one assembly welding pin.This inductance is inadequate due to the width of base simultaneously, so magnet ring length is inadequate, reduces inductance performance index.
Summary of the invention
The purpose of this utility model is that between the group that exists for traditional filter inductance, withstand voltage deficiency, winding have the problems such as waste, proposes the inductance that between a kind of group, high withstand voltage, winding improves without waste, performance.
The technical solution of the utility model is:
A kind of filter inductance, it comprises base, magnet ring, four windings and eight capillaries, eight described capillaries divide two rows to be arranged on below base, magnet ring is arranged on above base, one end of four windings is respectively on corresponding four capillaries being welded on a wherein row, is welded on four capillaries corresponding to another row after the other end of four windings all walks around magnet ring.
Magnet ring of the present utility model is arranged on the centre of base.
Four windings of the present utility model all enclose around 8 on magnet ring.
Winding welding of the present utility model is in the junction of capillary and base.
The both sides of base of the present utility model are equipped with the triangle step stoping magnet ring to roll.
The array pitch of two row's capillaries of the present utility model is 15.6-15.8mm.
In often row capillary of the present utility model, the needle gage of adjacent capillary is 7.4-7.6mm.
The side of base of the present utility model, is respectively equipped with eight grooves corresponding to eight capillaries, the outlet being welded on the winding on capillary through after respective slot to magnet ring solderless wrapped connection.
The beneficial effects of the utility model:
Inductance of the present utility model is because base needle gage is long, and be welded on printed board pad, pad diameter is 2.5mm, and the creepage distance in printed board also has 5mm, withstand voltage up to 4KV between group.
Inductance of the present utility model has four windings, is particularly suitable for three-phase four-wire system power supply input filter.Because array pitch is wide, this inductance magnet ring used is also long, so performance also improves.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is understructure schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of filter inductance, it comprises base 1, magnet ring 2, four windings 3 and eight capillaries 4, described eight capillaries 4 point two row is arranged on below base 1, magnet ring 2 is arranged on above base 1, one end of four windings 3 is respectively on corresponding four capillaries 4 being welded on a wherein row, is welded on four capillaries 4 corresponding to another row after the other end of four windings 3 all walks around magnet ring 2.The utility model has four windings, is particularly suitable for three-phase four-wire system power supply input filter.Because array pitch is wide, this inductance magnet ring used is also long, so performance also improves.
Magnet ring 2 of the present utility model is arranged on the centre of base 1.
Four windings 3 of the present utility model all enclose around 8 on magnet ring 2.
Winding 3 of the present utility model is welded on the junction of capillary 4 and base 1.
The both sides of base 1 of the present utility model are equipped with the triangle step 5 stoping magnet ring to roll.
The array pitch of two row's capillaries 4 of the present utility model is 15.7mm; Often arrange in capillary, the needle gage of adjacent capillary 4 is 7.5mm.This inductance is because base needle gage is long, and be welded on printed board pad, pad diameter is 2.5mm, and the creepage distance in printed board also has 5mm, withstand voltage up to 4KV between group.
The side of base 1 of the present utility model, is respectively equipped with eight grooves 6 corresponding to eight capillaries 4, the outlet being welded on the winding 3 on capillary 4 through after respective slot 6 to magnet ring 2 solderless wrapped connection.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
