Description

A kind of toroidal transformer
Technical field
The utility model is related to technical field of electronic components, specifically a kind of toroidal transformer.
Background technology
Toroidal transformer is a big type of electronic transformer, be widely used to household appliance and other technologies require compared with In high electronic equipment, it is mainly used for as power transformer and isolating transformer.
With electronic equipment outdoors, the moving field chance that some extraordinary electricity consumptions use in one's power it is more and more, to transformation The high pressure resistant aspect of device also has an increasingly higher demands, and when manufacture must all carry out the high voltage bearing management and control of product, to ensure product Security performance reach requirement.
Currently, the high voltage performance of enhancing transformer is mainly by increasing skeleton size, immersion oil uses, and is increased with this Discharging gap is added to ensure without arcing etc., however the requirement of this and product miniaturization, mobile, superelevation pressure resistance produces contradiction.
Utility model content
The purpose of this utility model is to provide a kind of toroidal transformer, which can not increase skeleton ruler Under the premise of very little, the high voltage performance of device is improved.
Technical solution adopted by the utility model to solve its technical problems is:
A kind of toroidal transformer, including annular outer cover, magnet ring, primary coil and secondary coil;The primary coil coiling On magnet ring, magnet ring is embedded in annular outer cover, and magnet ring is equipped with embedding layer with primary coil periphery;The secondary coil is wound in On annular outer cover, secondary coil is equipped with insulating layer with annular outer cover periphery.
Further, the annular outer cover side wall is equipped with U-lag in a strip shape, and U-lag is connected with annular outer cover inner cavity, The lead of primary coil is embedded in U-lag;The lead of secondary coil is located at the other side of annular outer cover relative to U-lag.
The utility model has the beneficial effects that:
One, the set-up mode for giving up traditional endless transformer and secondary coil, by primary coil and secondary wire Circle is wound on respectively on different mounting mediums, is realized be physically isolated by annular outer cover and embedding layer therebetween, improved exhausted Edge performance reaches high voltage bearing purpose.
Two, by U-lag, increase the port spacing of primary coil lead and secondary coil lead, to increase primary and secondary The proof voltage ability of coil.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the schematic diagram of the utility model annular outer cover and U-lag;
Fig. 3 is the A-A sectional views of Fig. 2;
Fig. 4 is the schematic diagram of the utility model magnet ring and primary coil;
Fig. 5 is the assembling schematic diagram of the utility model annular outer cover, magnet ring and primary coil;
Fig. 6 is the schematic diagram of the utility model embedding layer;
Fig. 7 is the schematic diagram of the utility model secondary coil.
Specific implementation mode
In conjunction with shown in Fig. 1~3, the utility model provides a kind of toroidal transformer, including annular outer cover 1a, magnet ring 2, primary Coil 3 and secondary coil 4;Annular outer cover 1a side walls are equipped with U-lag 1b in a strip shape, the inner cavity of U-lag 1b and annular outer cover 1a It is connected, annular outer cover 1a and U-lag 1b is preferably integrated plastic housing;In conjunction with shown in Fig. 4, primary coil 3 is wound on magnetic On ring 2;In conjunction with shown in Fig. 5, the magnet ring 2 of coiling primary coil is embedded in annular outer cover 1a, and the lead 3a of primary coil 3 is embedding In U-lag 1b;In conjunction with shown in Fig. 6, magnet ring 2 is equipped with embedding layer 5 with 3 periphery of primary coil;In conjunction with shown in Fig. 7, secondary wire Circle 4 is wound on annular outer cover 1a, and secondary coil 4 is equipped with insulating layer 6 with the peripheries annular outer cover 1a;The lead 4a of secondary coil 4 It is located at the other side of annular outer cover 1a relative to U-lag 1b.
In the preparation, first primary coil 3 is wound on magnet ring 2, is then embedded at the magnet ring of coiling primary coil In annular outer cover 1a;Then it is potted with epoxy resin, forms embedding layer 5;Then secondary coil 4 is wound in annular outer cover On 1a, then varnish is impregnated, insulating layer 6 is formed after toasted.
The set-up mode for giving up traditional endless transformer and secondary coil, by primary coil and secondary coil point It is not wound on different mounting mediums, i.e., primary coil is wound on magnet ring, secondary coil is wound on annular outer cover, the two Between realized and be physically isolated by annular outer cover and embedding layer, improve insulation performance, reach high voltage bearing purpose.By U-lag, The port spacing for increasing primary coil lead and secondary coil lead, to increase the proof voltage ability of primary and secondary coil.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation;Any technical person familiar with the field, it is all available in the case where not departing from technical solutions of the utility model ambit The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as The equivalent embodiment of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, according to the utility model Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment, still fall within this practicality In the range of the protection of new technique scheme.
