Abstract
The utility model discloses an ultrathin pulse transformer. According to the pulse transformer, the circuit part is packaged by an outer cover (1) and a bottom box (2) which are assembled in a clamped manner. The ultrathin pulse transformer is a wideband thin type pulse transformer, has a small size and is convenient to carry and is mainly applied to portable electronic products.
Description
Technical field
The utility model relates to field transformer, particularly a kind of ultra-thin formula pulse transformer.
Background technology
Transformer almost all will be used in all electronic products, and its principle is simple but different according to the technique for coiling meeting of different use occasion (different purposes) transformer.The function of transformer mainly contains: voltage transformation, impedance conversion, isolation, voltage stabilizing (magnetic saturation transformer) etc.The general coil that connects power supply is referred to as " primary winding; Voltage across this coil is referred to as " primary voltage ".The induced voltage that produces on secondary coil may be greater than or less than primary voltage, mainly is to be determined by " turn ratio " between primary winding and secondary coil.Therefore, transformer is divided into and is boosted and two kinds of step-down transformers.When aliving in the primary winding, just produce magnetic flux in the iron core (or magnetic core), make and induce voltage (or electric current) in the secondary coil.
Summary of the invention
The technical problem that the utility model mainly solves is: at the pulse transformer profile was excessive in the past, can't be applicable to the shortcoming on the slim electronic product, propose a kind of at the pulse transformer that can be at volume uses on the small and exquisite and portable type electronic product.
The technical scheme that adopts: the utility model discloses a kind of ultra-thin formula pulse transformer.Described pulse transformer utilization is encapsulated circuit part by enclosing cover and end box, and described enclosing cover and end box adopt may box-like assembling.
Wherein, described pulse transformer circuit part is made of 2 groups of coils, every group of coil is made of first magnetic core, second magnetic core and one group of insulated copper wire, with 4 insulated copper wires that are respectively four kinds of colors behind 17 circles of volume on first magnetic core, wherein the dichromatism copper cash is told and is turned round line, and volume 19 encloses on second magnetic core, and first, second group magnetic core is coupled together.
Wherein, described pulse transformer adopts two-sided circle wire casing, and insulated copper wire is located in the circle wire casing of two-sided circle wire casing both sides, and closely contacts with the circle line terminals.
Beneficial technical effects: the utility model is wideband, thin formula pulse transformer, and volume is little, is easy to carry, and is mainly used in portable type electronic product.
Description of drawings
Fig. 1 the utility model circuit part circuit diagram.
Fig. 2 the utility model encapsulating structure figure.
The two-sided circle wire casing structure of Fig. 3 the utility model figure.
Embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment adopts two kinds of volumes of A, B little, and thin thickness magnetic core, first magnetic core are that outside dimension is 3.25mm, and internal diameter size is the low-profile magnetic core of 0.78mm for 1.4mm thickness; Second magnetic core is that outside dimension is 2.54mm, and internal diameter size is the low-profile magnetic core of 0.7mm for 1.27mm thickness.Select this two kinds of low-profile magnetic core for use, in order to guarantee the product thickness requirement.When the body receiving inputted signal, A, the B magnetic core generation magnetic flux that interacts becomes the sine voltage of input into burst pulse shape output voltage.
With reference to Fig. 2, it is 2.19mm that this example reaches maximum ga(u)ge in shape, and outward appearance is small and exquisite, frivolous is this example outstanding feature the most, and in order to take into account this characteristics in every respect, product still continues these characteristics in the material assembling, adopted no buckle, may box-like assembling.
With reference to Fig. 3, adopt two-sided circle wire casing, line is closely contacted with the circle line terminals, solve the phenomenon of line and the loose contact of circle line terminals, and be convenient to circle line and welding.
Above content be in conjunction with optimal technical scheme to further describing that the present invention did, can not assert that the concrete enforcement of invention only limits to these explanations.Concerning the general technical staff of the technical field of the invention, under the prerequisite that does not break away from design of the present invention, can also make simple deduction and replacement, all should be considered as protection scope of the present invention.
Claims (2)
1. a ultra-thin formula pulse transformer is characterized in that, described pulse transformer utilization is encapsulated circuit part by enclosing cover (1) and end box (2), and described enclosing cover (1) and end box (2) adopt may box-like assembling.
2. ultra-thin formula pulse transformer according to claim 1 is characterized in that described pulse transformer adopts two-sided circle wire casing, and insulated copper wire is located in the circle wire casing (3) of two-sided circle wire casing both sides, and closely contacts with the circle line terminals.
