Description
Technical field
The utility model is related to a kind of high-current inductors.
Background technology
Electrical inductor assembly is commonly used in a variety of high current applications, such as switching power unit.Heavy-current inductor device assembly compares
Greatly, and bigger part is therefore occupied, and in many cases, occupies the main of their circuit boards mounted thereto
Part.This can lead to following problem：In order to provide for will be mounted electrical inductor assembly on circuit boards and other needed for
The size of the sufficient space of both electronic units, circuit board must be greatly increased.
Current high-current inductor, usually only a pair of of magnetic core, the power utilization of product is not high, winding generally use
Silk-covered wire coiling, the electric current that can be born are unsatisfactory.
Invention content
The technical problem to be solved by the present invention is to provide a kind of high-current inductor, performance is stablized, can bear compared with
High current, product bear to be not easy to be saturated when high current, and good heat dissipation is easy for installation.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of high-current inductor, including magnetic core, the magnetic core are provided with two groups, respectively first group of magnetic core and second altogether
Group magnetic core, first group of magnetic core and second group of magnetic core connect setting side by side, winding in first group of magnetic core and second group of magnetic core, this around
Group is superimposed by copper sheet and is formed, and attaching has connection copper foot, the company between first group of magnetic core and second group of magnetic core respectively at the both ends of winding
Seam gap is used for first group of magnetic core of cementation and second group of magnetic core, first group of magnetic core and second group of magnetic filled with epoxide-resin glue water layer
The side wall of core is additionally provided with insulating barrier.
The medium position of the side wall in first group of magnetic core and second group of magnetic core is arranged in the insulating barrier.
The medium position in first group of magnetic core and second group of magnetic core is arranged in the winding, and faces insulating barrier.
The insulating barrier and epoxide-resin glue water layer vertical arrangement.
First group of magnetic core and second group of magnetic core are U-shaped magnetic core.
The utility model performance is stablized, and larger current can be born, and product bears to be not easy to be saturated when high current, heat dissipation
It is good, it is easy for installation.

As shown in attached drawing 1,2 and 3, the utility model discloses a kind of high-current inductor, including magnetic core, and the magnetic core is total
It is provided with two groups, respectively first group of magnetic core 21 and second group of magnetic core 22, first group of magnetic core 21 and second group of magnetic core 22 are side by side
It is equipped with winding in connection setting, first group of magnetic core and second group of magnetic core, which is superimposed by copper sheet forms, the both ends difference of winding
Attaching has connection copper foot 4, and the connection gap between first group of magnetic core 21 and second group of magnetic core 22 is filled with epoxide-resin glue water layer 3
For first group of magnetic core of cementation and second group of magnetic core, the side wall of first group of magnetic core 21 and second group of magnetic core 22 is additionally provided with insulating barrier
1, using the insulating barrier as air gap, product space bigger, product is made to bear to be not easy to be saturated when high current.First group of magnetic core
All it is U-shaped magnetic core with second group of magnetic core.The bending of copper foot is connected, and the screens of protrusion can be set on the connection copper foot.Pass through two
The combination of a U-shaped magnetic core, makes product power utilization accomplish maximum.
Winding is made of 1.5mm copper sheets, and operation is convenient, and easy to operate, product good heat dissipation, client is easy for installation, bears
Electric current is big.
The medium position of the side wall in first group of magnetic core and second group of magnetic core is arranged in the insulating barrier.Winding setting is the
Medium position in one group of magnetic core and second group of magnetic core, and face insulating barrier.
The insulating barrier and epoxide-resin glue water layer vertical arrangement.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
