Abstract
The utility model discloses a double-inductor used for USB (universal serial bus) chargers, which comprises a base. The base is made of insulating materials and provided with a magnetic core, two windings made of copper wires are wound on the magnetic core, and two wire ends of the two windings are fixed to two sides of the base in parallel respectively; the base is shaped as a plate, a recess for fixing the magnetic core is arranged on the upper surface of the base, and the low end of the magnetic core is fixed in the recess. The double-inductor used for the USB chargers has a smartly designed structure, so that the manufacturing cost and raw material cost can be reduced remarkably, and the working performance and the production efficiency of the double-inductor can be improved.
Description
Technical field
The utility model relates to inductor, particularly a kind of two inductors that are used for the USB charger.
Background technology
In the prior art, inductor is a kind of electronic component that is in daily use, and inductor is to be converted into magnetic energy to electric energy and the element that stores.The similar of inductor is in transformer, and common inductor has only a coiling group.Inductor has certain inductance, and it only stops change in current.If there is not electric current to pass through in the inductor, then it stops electric current to flow through it; If there is electric current to flow through it, when then circuit breaks off it will to attempt to keep electric current constant.Inductor is claimed choke, reactor, dynamic reactor again.
The general pair inductors that adopt in the micro USB charger, it is provided with two coiling groups.Two inductors commonly used mainly comprise I shape magnetic core, magnet frame, copper cash and base.There is following shortcoming in these two inductor structures commonly used:
1, product cost is high, because the needed raw material types of product is many, and complex manufacturing technology, cause material cost and cost of labor all very high.
2, produce the fraction defective height, this product magnetic core splits magnetic and the easy superelevation of product thickness easily.
The utility model content
The purpose of the utility model is, a kind of two inductors that are used for the USB charger reasonable in design are provided, and its structural design is ingenious, can reduce the manufacturing cost and the cost of raw material significantly, improves product service behaviour and production efficiency.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of two inductors that are used for the USB charger; It comprises the base processed by insulating material; Be provided with a magnetic core in this base, be arranged with the two coiling groups processed by copper cash on the said magnetic core, two line ends of this two coilings group are fixed in the both sides of this base respectively side by side.
Said base is tabular, in the upper surface of this base be provided with one be used for fixing said magnetic core recess, the lower end of said magnetic core is fixed in this recess.
Be provided with one first end pin and one the 4th end pin in the left side of this base; Be provided with one second end pin and one the 3rd end pin in the right side of this base; Be respectively equipped with on this first end pin, the second end pin, the 3rd end pin and the 4th end pin one be used to be connected said coiling group line end the tin dish; Wherein two line ends of a coiling group are connected on the tin dish on this first end pin and the second end pin, and two line ends of this another coiling group are connected on the tin dish on the 3rd end pin and the 4th end pin.
Said magnetic core is a cylinder, and the top of this magnetic core is provided with a top board.
The beneficial effect of the utility model is: the utility model structural design is ingenious, can reduce the manufacturing cost and the cost of raw material significantly, improves product service behaviour and production efficiency.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
