Description

EF type high frequency transformer

Technical field

The utility model relates to field of electronic devices more particularly to a kind of EF type high frequency transformers.

Background technique

With the development of national economy, society is growing to electronics and IT products demand, effectively promotes electronics industry High speed development, and have a extensive future using high frequency transformer as the electronic component of representative, preceding institute is brought not to transformer manufacturing industry Some opportunities.

In the universal production technology of current high frequency transformer industry are as follows: according to product requirement the material got ready --- copper Line, margin tape, insulating tape, casing etc. are wound on the front-end-of-line that line packet is completed on skeleton；Followed by scolding tin, group are loaded onto The components such as magnetic core carry out a series of step sequences such as dispensing, immersion oil again later, are completed last part technology.Product is on functional safety Usually have following technical requirements: electric equipment compartment as defined in ensuring to keep between each winding and components of product away from, creepage distance, Insulate penetration range etc., while reaching corresponding dielectric strength and insulation resistance.To reach above-mentioned technical requirements, current high frequency Transformer production producer mostly uses CNC single shaft machine to carry out coiling, needs when coiling that barricade is arranged in the outlet portion of stitch and wears Pipe, with electric equipment compartment as defined in keeping away from, creepage distance, insulation penetration range etc..But this mode complex procedures cannot achieve certainly Dynamicization, cost of labor and material cost remain high, waste of material, are difficult to realize large-scale production, and being unable to satisfy society needs Capacity requirements transformer production enterprise is proposed, or even by market.To avoid such case from occurring, realize automatic Changing, improving production efficiency, reduction cost of labor and/or material cost is inevitable choice.And used skeleton is in industry Conventional product, structure lack the feature of safety requirements and automation.Therefore it needs to develop to be able to satisfy product safety and automation The skeleton of production, then cooperate the equipment such as fully automatic wire winding machine to realize automatic production, saves manpower, improving production efficiency, quality, Reduce the consumption of material.

Utility model content

Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide a kind of structure it is simple, at This is low, save barricade and casing and can automated production EF type high frequency transformer.

The technical scheme adopted by the utility model is the EF type high frequency transformer includes frame body, in the bone The intermediate position of frame ontology is set as winding slot, and the both ends of the frame body are provided with several stitch, in the winding slot around It is formed with winding, the winding leads to lead-out wire and is connected with the stitch, and the periphery of the frame body is provided with magnetic core, It is provided with wire lead slot in the frame body and between two stitch of arbitrary neighborhood, at two ends of the frame body Portion is provided with the hanging wire to match with the wire lead slot and follows closely, the number of the number and the stitch of the wire lead slot and hanging wire nail Mesh is consistent, and in the position close to the winding slot, smoothly transition is connect the lead trench bottom with the bottom of the winding slot, The downside of the hanging wire nail and the exterior bottom flush of the wire lead slot.

Above scheme can guarantee that the lead-out wire of winding is adjacent to wire lead slot as it can be seen that the setting followed closely by wire lead slot and hanging wire Bottom further around cross hanging wire nail and be connected on stitch, safe distance is maintained between lead-out wire and tap to realize, thus The winding that the structure of no setting is required barricade and sleeve-penetrating, wire lead slot and hanging wire nail keeps the lead-out wire of winding other with transformer draws It maintains safe distance between outlet and remaining electrification components and is not directly contacted with, while regarding skeleton stitch to winding wire packet distance The case where, the increase distance for adjusting the distance inadequate avoids the insulation of sweating heat damage wires, to guarantee the insulation of transformer and indulge Insulation performance.It is at low cost so the utility model structure is simple, save barricade and casing and can automated production.

Further, the hanging wire nail is in cube shape, cylindric, elliptic cylindrical shape, triangle column.It can be seen that hanging wire is followed closely Structure can be it is diversified, however it is not limited to a certain form, mainly play the role of limit lead-out wire position.

Specific embodiment

As shown in Figures 1 to 5, in the utility model, the EF type high frequency transformer includes frame body 1, in the bone The intermediate position of frame ontology 1 is set as winding slot 2, and the both ends of the frame body 1 are provided with several stitch 3, the winding slot 2 It is inside wound with winding 4, the winding 4 leads to lead-out wire 5 and is connected with the stitch 3, the periphery setting of the frame body 1 There is magnetic core 6, wire lead slot 7 is provided in the frame body 1 and between two stitch 3 of arbitrary neighborhood, in the bone Two ends of frame ontology 1 are provided with the hanging wire nail 8 to match with the wire lead slot 7, the wire lead slot 7 and hanging wire nail 8 Number it is consistent with the number of the stitch 3, in the position close to the winding slot 2,7 bottom of wire lead slot and the coiling Smoothly transition connects for the bottom of slot 2, the downside of the hanging wire nail 8 and the exterior bottom flush of the wire lead slot 7.The extension Tailor's tack 8 is the bar shape of kidney-shaped in cube shape, cylindric, elliptic cylindrical shape, triangle column or cross section.In the present embodiment, institute State bar shape of the hanging wire nail in cross section for runway.

The utility model makes winding leading-out wire be close to lead trench bottom by hanging wire nail, then keeps lead-out wire straight by wire lead slot It is connected to the winding rising in winding slot and starts coiling after point, after the completion of winding technique, ending line also corresponding draws from its Wire casing leads to corresponding stitch through hanging wire nail and twines head broken string, with after adhesive tape 9 between automatic coil winding machine covering further around next winding is made, directly To completion wire winding.The structure of wire lead slot and hanging wire nail make the lead-out wire of winding and the other winding leading-out wire of transformer and its Maintain safe distance between remaining band electric parts and be not directly contacted with, at the same regard skeleton stitch to line packet apart from the case where, to away from With a distance from inadequate increase, the insulation of sweating heat damage wires is avoided, to guarantee the insulation and minor insulation performance of transformer.

Compared with traditional transformer framework structure, the utility model can cancel the barricade and winding leading-out wire of inefficiency Sleeve-penetrating technique, and properties of product do not reduce, and reduce old artificial, the reduction possible quality defect of manual process, while this is tied Structure is also able to cooperate the raising production efficiency of automatic coil winding machine tenfold.Have again and makes because no longer needing to insulate barricade with insulating sleeve Each product avoids the consumption of insulation barricade and insulating sleeve, by the yield of the annual switch transformer in China now, in ring It protects and just seems with important social effect energy-efficient today.
