Abstract
The utility model discloses a kind of choke transformer, comprise skeleton, be wound on the high-tension coil winding on skeleton and low-voltage coil winding, be enclosed within magnetic core and the high pressure stitch be connected on skeleton and low pressure stitch that high-tension coil winding is connected with on low-voltage coil winding and with skeleton, high-tension coil winding is electrically connected with high pressure stitch by the high-voltage connection at its two ends, low-voltage coil winding is electrically connected with low pressure stitch by the low-voltage lead at its two ends, high-tension coil winding and low-voltage coil winding are made by cotton covered wire, wherein, the two ends high-voltage connection of high-tension coil winding, on first lap coil and last lap coil, all cover has insulative.The utility model has the advantage of: can effectively avoid high-tension coil winding to puncture, long service life.
Description
Technical field
The utility model relates to a kind of transformer, particularly a kind of choke transformer.
Background technology
When choke transformer uses in high-frequency circuit, for weakening skin effect, the coil windings on it all can adopt the cotton covered wire be woven into by multiply mutually insulated thin wire usually.At present, coil windings on existing choke transformer is all generally directly be wound on skeleton, there is a weak point in the choke transformer of this structure: when choke transformer energising moment in actual application, high-tension coil winding easily punctures because being subject to instantaneous pressure, this situation that punctures is between high-tension coil winding and its two ends go between, especially easily occur between the first lap coil of high-tension coil winding and the second turn coil and between the turn coil last of high-tension coil winding and turn coil second from the bottom, and high-tension coil winding is once puncture, the coil outer layer insulation yarn that puncture place position so occurs just very easily is fallen by high temperature ablation, thus greatly can affect the insulation property of this place's coil, choke transformer is finally caused to damage, greatly reduce the normal service life of choke transformer.
Utility model content
The technical problems to be solved in the utility model is, provides one can effectively avoid high-tension coil winding to puncture, the choke transformer of long service life.
For solving the problems of the technologies described above, the utility model provides and a kind ofly adopts the choke transformer of following structure: comprise skeleton, be wound on the high-tension coil winding on skeleton and low-voltage coil winding, be enclosed within magnetic core and the high pressure stitch be connected on skeleton and low pressure stitch that high-tension coil winding is connected with on low-voltage coil winding and with skeleton, high-tension coil winding is electrically connected with high pressure stitch by the high-voltage connection at its two ends, low-voltage coil winding is electrically connected with low pressure stitch by the low-voltage lead at its two ends, high-tension coil winding and low-voltage coil winding are made by cotton covered wire, wherein, the two ends high-voltage connection of high-tension coil winding, on first lap coil and last lap coil, all cover has insulative.
Choke transformer described in the utility model, wherein, insulative is made up of polytetrafluoroethylmaterial material.
After adopting said structure, the utility model has the following advantages: because the utility model choke transformer is at the two ends high-voltage connection of high-tension coil winding, on first lap coil and last lap coil, all cover has insulative, therefore make between high-tension coil winding and its two ends go between, insulating properties between the first lap coil of high-tension coil winding and the second turn coil and between the turn coil last of high-tension coil winding and turn coil second from the bottom strengthens greatly, thus effectively prevent the situation that high-tension coil winding punctures and occur, and then effectively ensure that the useful life of the utility model choke transformer.
Accompanying drawing explanation
Fig. 1 is the main TV structure appearance schematic diagram of the utility model choke transformer;
Fig. 2 is perspective view when cover has the high-tension coil winding of insulative on skeleton in the utility model choke transformer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model choke transformer is described in further detail.
As depicted in figs. 1 and 2, in this embodiment, the utility model choke transformer comprises skeleton 1, be wound on the high-tension coil winding 2 on skeleton 1 and low-voltage coil winding 3, be enclosed within magnetic core 4 and the high pressure stitch 5 be connected on skeleton 1 and low pressure stitch 6 that high-tension coil winding 2 is connected with on low-voltage coil winding 3 and with skeleton 1, high-tension coil winding 2 is electrically connected with high pressure stitch 5 by the high-voltage connection 7 at its two ends, low-voltage coil winding 3 is electrically connected with low pressure stitch 6 by the low-voltage lead 8 at its two ends, high-tension coil winding 2 and low-voltage coil winding 3 are made by cotton covered wire, the two ends high-voltage connection 7 of high-tension coil winding 2, on first lap coil and last lap coil, all cover has insulative 9, insulative 9 is made up of polytetrafluoroethylmaterial material.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection range that the utility model claims determine.
