Abstract
The utility model discloses an injection-molding type high-frequency transformer, comprising a framework, a magnetic core, a primary winding, a secondary winding and pin ends, wherein each pin end is respectively arranged on two sides of one end of the framework, a pin of one pin end on one side is connected with a wrapping wire of the primary winding, a pin of one pin end on the other side is connected with a wrapping wire of the secondary winding, the primary winding is wound around a cavity of the framework, a plastic layer is injected on the surface of the primary winding, the secondary winding is connected with the plastic layer in a winding manner, and a layer of insulating tape is coated on the surface of the secondary winding. The injection-molding type high-frequency transformer disclosed by the utility model has the advantages of automatic operation, high efficiency without a retaining wall tape, an interlayer insulating tape and an insulating sleeve, excellent voltage resistance and insulation performance and smaller volume..
Description
Technical field
The utility model relates to transformer, specifically is meant a kind of injection molding high frequency transformer.
Background technology
High frequency transformer generally is made up of skeleton, magnetic core, elementary winding, secondary winding, margin tape, and elementary winding solderless wrapped connection after on the skeleton, is provided with margin tape at the two ends of elementary winding; The exit of elementary winding is connected with stitch after being with insulating sleeve; Then, be wound with the layer insulation adhesive tape on the first surface of group winding, with secondary winding on the layer insulation adhesive tape; At the surperficial wrap insulate adhesive tape of secondary winding, the exit of secondary winding is connected with stitch after being with insulating sleeve then.Existing high frequency transformer is owing to adopt said structure, and its a lot of operations can't realize automated job, make production efficiency low, and labour intensity is big, and reliability is not high.The high frequency transformer of this class formation makes that the leakage inductance of product is bigger owing to adopted margin tape and sleeve pipe.
The utility model content
The purpose of the utility model provide a kind of automated job, efficient high, exempt from margin tape, exempt from the layer insulation adhesive tape and exempt from insulating sleeve, withstand voltage good, insulation property are good, volume high frequency transformer still less.
To achieve these goals; The utility model is designed a kind of injection molding high frequency transformer, and it comprises skeleton, magnetic core, elementary winding, secondary winding and stitch end, and the stitch end is installed in the both sides of skeleton one end respectively; Wherein the stitch on the stitch end of a side is connected with the coiling of elementary winding; Stitch on the stitch end of opposite side is connected with the coiling of secondary winding, and described elementary winding solderless wrapped connection is injected with one deck plastic layer on the surface of elementary winding on skeleton bone chamber; The secondary winding solderless wrapped connection is coated with one deck insulating tape at secondary winding on plastic layer.
The mode that the utility model injection molding high frequency transformer winds the line through automation earlier; On the skeleton around on first group winding, then through injection molding way, be provided with plastic layer on the first surface of group winding; Just the exit of group winding directly is connected with stitch; Plastic layer has played to isolate and protect and has acted on, and on plastic layer, has installed around time group winding, and the exit of inferior group of winding directly is connected with the stitch of primary side.Owing to adopt said structure, the production and processing mode of the utility model injection molding high frequency transformer can automated job, reduces artificial input, improves production efficiency of products and reliability, and withstand voltage insulation property are better, and the volume of product can further reduce.Simultaneously, cancel margin tape and insulating sleeve, reduced the leakage inductance of product.
Description of drawings
Fig. 1 is the perspective view of the utility model injection molding high frequency transformer;
Fig. 2 is the sectional structure sketch map of the utility model injection molding high frequency transformer.
Embodiment
For the ease of those skilled in the art's understanding, will combine specific embodiment and accompanying drawing that the structural principle of the utility model is done further to describe in detail below.
Like Fig. 1, shown in Figure 2; A kind of injection molding high frequency transformer, it comprises skeleton, magnetic core 2, elementary winding 3, secondary winding 4 and stitch end 5, the stitch end is installed in the both sides of skeleton 1 one ends respectively; Wherein the stitch 6 on the stitch end of a side is connected with the coiling of elementary winding 3; Stitch 6 on the stitch end of opposite side is connected with the coiling of secondary winding 4, and described elementary winding 3 solderless wrapped connections are injected with one deck plastic layer 8 on the surface of elementary winding 3 on skeleton 1 bone chamber; Secondary winding 4 solderless wrapped connections are coated with one deck insulating tape 10 at secondary winding 4 on plastic layer 8.
The elementary coiling of the utility model, injection moulding plastic layer, secondary rolling thread etc. can both be realized automated production.Can enhance productivity greatly, strengthen the production of product.
Foregoing is merely the preferred embodiment of the utility model, is not the embodiment that is used to limit the utility model, and those skilled in the art are according to the design of the utility model, and appropriate adaptation of having done or modification all should be within the protection ranges of the utility model.
