Abstract
The invention discloses a switching power supply transformer for an external power supply of a display. The transformer is characterized by comprising a framework, a magnetic core, a primary winding unit, a secondary winding unit and pins, wherein the pins are arranged at the bottom of the framework; the primary winding unit and the secondary winding unit are wound on the framework, and connected with the pins by lead grooves in the framework; and distances between the lead grooves are less than 7mm. The safety of the transformer can further be ensured by increasing lead distances; the secondary winding unit adopts a double insulation line, so that a winding space of the transformer can be used to the greatest extent, and a space utilization ratio can reach 100%; a ferrite serves as the magnetic core, so that the transformer is applicable to a wider temperature range; and energy consumption and heat can be reduced effectively.
Description
Technical field
The present invention relates to a kind of display external power supply switching mode power supply transformer.
Background technology
Along with the application of consumer electronics thin typeization and touching technique, according to the different market demands, aspect display, integrated computer, former be installed on and the switch inside power module is substituted by external Miniature Power Unit adapter.So both be conducive to reduce the thickness of product, saved cost, also be conducive to standardization, the production in enormous quantities of adapter.
But, the switching mode power supply transformer of Sheng Chaning in the market, its elementary winding element, secondary winding unit all adopt common enamelled wire, cause the transformer coiling space availability ratio low relatively, and volume of transformer can't diminish, and can't adapt to miniaturization is the market demand.
The common enamelled wire of elementary winding element, the employing of secondary winding unit is owing to the enamelled wire self-characteristic simultaneously, and insulation effect is relatively poor relatively, is unfavorable for the stability of transformer, influences product quality.
Because the magnetic core of present transformer adopting is common magnet, its power consumption is higher, and work in can produce bigger heat, not only higher relatively the but also expensive transformer that influences of heat that produce of use cost is stability, fail safe is relatively low.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, provide a kind of and can effectively cut down the consumption of energy, improve the display external power supply switching mode power supply transformer of transformer stability.
Technical scheme: in order to realize above purpose, a kind of display external power supply switching mode power supply transformer provided by the invention, comprise skeleton, magnetic core, elementary winding element, the secondary winding unit, pin, described magnetic core is located at skeleton inside, described pin is located at the skeleton bottom, described elementary winding element, the secondary winding unit all around with skeleton on and link to each other with pin by the lead-in wire groove on the skeleton, described skeleton base is provided with the lead-in wire groove, described lead-in wire separation far is not less than 7mm, far away by increasing the distance that goes between between the groove, can further guarantee the fail safe of transformer, common transformer transmitting range is 2000m, after the distance of increase lead-in wire groove was far away, transmitting range was more than the 5000m, has improved transmission efficiency and fail safe greatly.
Described secondary winding unit adopts the double insulation line, effectively improves the insulation effect of transformer, makes and does not use margin tape and sleeve pipe also can satisfy the safety requirement, saves production cost, and also can simplify production stage, increases work efficiency; Also can utilize the characteristic of double insulation line, the winding space that improves skeleton greatly is efficient, makes the winding space utilance of transformer reach 100%, it is original 75% that the transformer of same 30w for example, volume then are reduced into, and significantly reduced volume of transformer, make it lighter, enlarge the scope of application.
Described magnetic core is ferrite, because ferritic self-characteristic can effectively enlarge temperature range, improves the stability of transformer, can also cut down the consumption of energy, and saves production cost.
Operation principle: a kind of display external power supply switching mode power supply transformer, comprise skeleton, magnetic core, elementary winding element, secondary winding unit, pin, described magnetic core is located at skeleton inside, described elementary winding element, the coiling of secondary winding unit link to each other with pin with the magnetic core outer rim and by the lead-in wire groove on the skeleton, described skeleton base is provided with the lead-in wire groove, and described pin is located at the skeleton bottom.
Beneficial effect: the distance of compared with prior art inventing by increasing between the lead-in wire groove far improves fail safe, and the validity that transmits, and is that 2000m increases to 5000m by original transmitting range.
Secondary winding of the present invention unit improves insulation effect by adopting the double insulation line, increases transformer stability.
The present invention is by adopting the double insulation line with the secondary winding unit, can maximally utilise the winding space of skeleton, make the space availability ratio of skeleton reach 100%, thereby reduce the volume of transformer, make that the scope of application of transformer is wider, be conducive to improve the market competitiveness.
The present invention by with ferrite as magnetic core, can enlarge the comfort zone of transformation, can also reduce power consumption when improving the stability of product, reduce the heat that transformer produces, make that the longer service life of transformer is of a specified duration.
