Description
Technical field
The utility model relates to inductor field, is specifically related to a kind of U-shaped PFC inductance.
Background technology
PFC inductance its due to magnetic core be annular, when coiling, group is wanted manual and is wound around along magnetic core, and it is higher to coil requirement, and the aluminium enamel-covered wire that intensity is lower can not be adopted, therefore great majority adopt copper cash to carry out coiling, and cost is higher, and manual coiling processing is inconvenient, and coiling trouble.
Utility model content
The utility model, for the problems referred to above, provides a kind of U-shaped PFC inductance.
The utility model provides: a kind of U-shaped PFC inductance, it comprises U-shaped upper magnetic core and U-shaped lower magnetic core, the outer sheathed plastic sheath of upper and lower magnetic core, base is provided with bottom lower magnetic core, winding around outside two vertical portions of described lower magnetic core, described coil is flatwise coil, described flatwise coil comprises inside and outside two circles, and layering coiling, pin in the wiring of coil and base is welded and fixed, the weld of wiring and pin arranges epoxy resin, is fixedly connected with between described upper magnetic core with lower magnetic core by epoxy resin.
Pin containing cavity is provided with in described base.
Described containing cavity is F type groove.
Described base distributes in two separate ranks, and each row is respectively equipped with 4 pins, and 4 pins are connected with coil one end.
Pin is placed with in pin containing cavity, infusion epoxy resin in described pin containing cavity.
Described flatwise coil layered windings, and there is gap between every layer.
Described coil is that aluminium enamel-covered wire is entwined.
The utility model is by the Magnetic Core Design of upper and lower packing, on can passing through after the good coil of coiling, next card is installed, it is easy for installation, and coil winding can be made to adopt mechanical coiling, reduce production difficulty, and coil and pin wrap up pad by epoxy resin, effectively can prevent its oxidation that is corroded, improve its life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is exploded perspective view of the present utility model.
Fig. 3 is the exploded perspective view of upper magnetic core and plastic sheath.
Fig. 4 is the floor map of base.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of U-shaped PFC inductance, it comprises U-shaped upper magnetic core 3 and U-shaped lower magnetic core, the outer sheathed plastic sheath 10 of upper and lower magnetic core, base 2 is provided with bottom lower magnetic core 4, winding around 1 outside two vertical portions of described lower magnetic core 4, described coil 1 is flatwise coil, described flatwise coil comprises inside and outside two circles, and layering coiling, pin 7 in the wiring of coil 1 and base 2 is welded and fixed, and the weld of wiring and pin 7 arranges epoxy resin 6, and described upper magnetic core 3 is fixedly connected with by epoxy resin 6 with between lower magnetic core 4.
The utility model is by the Magnetic Core Design of upper and lower packing, on can passing through after the good coil 1 of coiling, next card is installed, it is easy for installation, and coil 1 coiling can be made to adopt mechanical coiling, reduce production difficulty, and coil and pin wrap up pad by epoxy resin, effectively can prevent its oxidation that is corroded, improve its life-span.
As shown in Figure 4, be provided with pin containing cavity 9 in described base 2, described containing cavity 9 is F type groove, described base distributes in two separate ranks, and each row is respectively equipped with 4 pins, and 4 pins are connected with coil one end, pin is placed with in pin containing cavity, infusion epoxy resin in described pin containing cavity.Prevent pin to be oxidized, many pin connecting coil one end, can realize passing through of big current simultaneously.
Described flatwise coil layered windings, and there is gap between every layer, adopt gap design, effectively can improve radiating effect.
Owing to can adopt mechanical coiling, therefore coil can be entwined for aluminium enamel-covered wire, overcomes aluminium enamel-covered wire insufficient strength originally, the deficiency of not easily coiling.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
