Abstract
The invention discloses a transformer suitable for a switch power supply, and the transformer comprises an iron core element which comprises a plurality of flat laminations in parallel stacked together, wherein the lamination comprises an anti-skidding layer on which a plurality of holes are arranged, the lamination comprises an E-shaped lamination and a second lamination both which are together formed into the shape of the Chinese character 'sun', the contact surfaces of the E-shaped lamination and the second lamination are respectively provided with a groove, the second lamination is provided with a fixture block matching the groove, and the transformer has the advantages of steady iron core element structure and reliable lamination contact, thus the transformer isn't easy to displace, and the phenomenon of power reduction and coil heating can be avoided in use.
Description
Technical field
The present invention relates to a kind of transformer being applicable to Switching Power Supply.
Background technology
Transformer utilizes mutual inductance principle to change alternating voltage, is made up of primary coil, secondary coil and iron core.The structure of existing transformer core comprises multiple lamination, and lamination comprises the lamination element that section is " I " and " E ", and I lamination and E lamination form " day " font lamination.The center arm of E lamination is positioned at the center of bobbin.Because lamination is the superposition that interlocks one by one, namely after the I lamination of ground floor and the docking of E lamination, the lamination of the second layer is assembled on iron-core element in the opposite direction, and namely the neighbouring of I lamination is E lamination.But, this structure in use there will be problem, namely must ensure the fixing of I lamination and E lamination position, because I lamination and E lamination are contact, it easily goes wrong, the i.e. movement of I lamination and the easy occurrence positions of E lamination, make both loose contacts, be similar to iron core and reduce, reactance is reduced, power also reduces thereupon, even makes coil heating or burn out time serious.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of transformer being applicable to Switching Power Supply, the Stability Analysis of Structures of its iron-core element, lamination contact stabilization, and Bu easy Fa Sheng Nuo position, avoids the phenomenon such as power reduction or coil heating in use procedure.
The present invention's adopted technical scheme that solves the problem is:
A kind of transformer being applicable to Switching Power Supply, comprise iron-core element, described iron-core element comprises multiple multiple smooth lamination paralleled be stacked, described lamination comprises skid resistant course, described skid resistant course is provided with multiple hole, and described lamination comprises E lamination and the second lamination, and formation " day " font pieced together by described E lamination and the second lamination, described E lamination and the second lamination contact-making surface are provided with groove, the second described lamination are provided with the fixture block with groove match.
The present invention improves prior art, one: between adjacent two laminations, arrange skid resistant course, once laminated sheet package is good, owing to being in impaction state between lamination, skid resistant course makes its not easily the moving of occurrence positions, and lamination is stablized; Its two: due to iron-core element be generally bag paint iron core, use in the environment that pressure is large, mutually push between iron-core element, there is the impaired situation of varnish, varnish damages can cause the situations such as iron core heating, skid resistant course further can play cushioning effect, avoids pushing the situation causing varnish breakage; Its three: on E lamination, be provided with groove and the second lamination be provided with the fixture block with matching grooves, fixture block is stuck in groove, increase the contact-making surface of E lamination and the second lamination, when the position of E lamination and/or the second lamination is moved, the part of fixture block is also being stuck in groove, E lamination and the second lamination still contact well, strengthen the stability of core structure.
As preferably, the section of the second described lamination is " E " font.
As preferably, the section of the second described lamination is " I " font.
Further, the degree of depth of described groove has 0.1 centimetre at least.
Further, the degree of depth of described groove is 0.2 centimetre.
To sum up, the invention has the beneficial effects as follows:
1, the present invention arranges skid resistant course between adjacent two laminations, it not only can make lamination not easily move, strengthen the stability of core structure, the situation of the varnish breakage that iron core excessive compression also can be avoided to cause, avoids power reduction or coil heating burnout phenomenon in use procedure.
2, the present invention is provided with groove and the second lamination is provided with the fixture block with matching grooves on E lamination, fixture block is stuck in groove, increase the contact-making surface of E lamination and the second lamination, when the position of E lamination and/or the second lamination is moved, the part of fixture block is also being stuck in groove, E lamination and the second lamination still contact well, strengthen the stability of core structure.
