Utility model's advantage lies in: the stitch material be the tin -coated copper, good anti -corrosion performance has, have certain intensity and hardness again, the formability is easy welding again well, the bottom both sides of transformer body are equipped with reserve stitch groove no. 2, and when a stitch groove appearance damaged, continuation use on stitch no. 2 was inserted to removable one -tenth L type stitch, the utility model discloses a connected mode of stitch for the structure that the in -process can not damage the transformer body is being dismantled to the transformer, has prolonged the life of transformer.
Description
Technical field
This utility model relates to technical field of electronic devices, is specifically related to a kind of miniature transformer in LED.
Background technology
Transformator (Transformer) be the principle utilizing electromagnetic induction to change the device of alternating voltage, main member is primary coil, primary coil, skeleton and magnetic core.Transformator has large-scale and small-sized, and have plug-in unit also has paster, and generally, small-sized plug-in unit transformator is often plugged on circuit board use.The function of transformator is power transmission, voltage transformation and being dielectrically separated from, as a kind of main soft magnetism electromagnetic component, power technology and Power Electronic Technique are widely used, transformator can be applied at present in the circuit board of LED, but after existing transformator is plugged into circuit board, owing to the number of pins of transformator is more, and pin is directly anchored on plastic insulation skeleton, once need to change, dismantlement work is extremely difficult, the transformator disassembled, pin damages due to the time longer plastic skeleton causing its periphery scalded by electric cautery, pin has loosened or has dropped, then transformator the most also damages and scraps, shorten the life-span of transformator, cause the waste of electronic device.
Utility model content
This utility model provides a kind of miniature transformer in LED, it is simple in structure and convenient in use, and it uses the connected mode of stitch so that transformator will not damage the structure of transformer body in unloading process, extends the service life of transformator.
For reaching above-mentioned purpose, utility model have employed following technical proposal: a kind of miniature transformer in LED, including housing and the transformer body being arranged on enclosure interior, it is stained with adhesive tape on described housing, described transformer body includes the skeleton being arranged on transformer body center, it is provided with through hole in described skeleton, it is provided with magnetic core in described through hole, it is tied with coil on described skeleton, described coil is divided into secondary coil and primary coil, described secondary coil is isolated by insulation film with primary coil joint, described primary coil surrounding is stained with one layer of insulating tape；The both sides, bottom of described transformer body are equipped with bracing wire groove and stitch groove one, and the two bottom sides of transformer body is provided with standby stitch groove two, is inserted with stitch in described stitch groove one.
At above-mentioned a kind of miniature transformer in LED, described secondary coil is conductive copper with the material of primary coil.
At above-mentioned a kind of miniature transformer in LED, described insulation film is PET insulation film.
At above-mentioned a kind of miniature transformer in LED, the material of described stitch is tin-coated copper.
The utility model has the advantage of: the tape surface being stained with on described housing can be with spray printing product code and numbering, it is easy to differentiate.Described secondary coil is conductive copper with the material of primary coil, has preferable longevity, the suitability, electric conductivity.Described insulation film is PET insulation film, has good insulation preformance, anti-breakdown voltage advantages of higher, and described primary coil surrounding is stained with one layer of insulating tape, plays insulation and the effect of protection primary coil.The both sides, bottom of described transformer body are equipped with bracing wire groove and stitch groove one, are inserted with stitch in described stitch groove one, and its material is tin-coated copper, have good corrosion resistance, have again certain intensity and hardness, and good moldability is the most easily welded.The two bottom sides of transformer body is provided with standby stitch groove two, and when damaging occurs in stitch groove one, replaceable l-shaped stitch is inserted on stitch two and is continuing with.This utility model uses the connected mode of stitch so that transformator will not damage the structure of transformer body in unloading process, extends the service life of transformator.
