Description
Technical field
The present invention relates to a kind of reversed phase converter, refer to a kind of plural high-pressure side that produces especially, the reversed phase converter that uses with the cold-cathode tube that relative populations is provided.
Background technology
Known, general reversed phase converter is that a magnetic core is set in the roll, coil with identical or different line footpath is wound in first siding ring and second siding ring on roll again, coat with a housing again after twining first siding ring and second siding ring on this magnetic core, so can constitute the reversed phase converter of an induction coil; And LCD now (LCD) is interior in order to luminous module backlight (Back LightModule) the cold cathode fluorescent lamp pipe (CCFL) high-effect and that external form is light and handy that uses, need to drive with high-tension electricity, so must make cold cathode fluorescent lamp pipe (CCFL) luminous by reversed phase converter, and form the light source of LCD (LCD).
Because display is tending towards maximizing now, need to use many cold cathode fluorescent lamp pipes just to be enough to supply its light source, and preferable display effect is also arranged, the demand degree that provides a plurality of cold cathode fluorescent lamp pipes to use with single reversed phase converter is more and more higher relatively; See also TaiWan, China patent certificate M267607 patent, be existing known reversed phase converter, this patent is by twining multi-turn line body around the district in primary side, and then produce more flux relatively, this just can produce high pressure for using the required of cold cathode fluorescent lamp pipe more than one in primary side around the district, should existing known coil be to be set around on the drum stand of a thread blank pipe shape structure, and utilize the two compartment sheet that drum stand is divided into three sections, a pair of primary side that three sections are respectively both sides around the district and middle primary side around the district.
From the above, then must increase the winding turns of primary side if will produce high pressure around the district, but primary side is pushed and limited field around the district by primary side around the space, both sides in district, make coiling only can upwards pile height, also can cause the difficulty that is assembled on the circuit board, and the problem that causes the reversed phase converter temperature overheating easily, on the other hand, if will reduce the high temperature that coiling produces, then must lower the temperature by the caliber that increases coiling around the district, but the winding space of primary side around the district limited to, and reduced the number of turns that can wind the line in primary side, then certainly will influence the voltage output of reversed-phase transformer, therefore the cold cathode fluorescent lamp pipe that can dispose also is limited.
Moreover, if increase the length of primary side,, then must dispose long magnetic core to increase winding turns around the district, can't produce certain quality to this magnetic core, certainly will influence the effect of reversed phase converter.
This shows that above-mentioned existing reversed phase converter obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that reversed phase converter exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of reversed phase converter of new structure, just become the current industry utmost point to need improved target.
