Abstract
The utility model discloses a widened framework used for a transformer. The widened framework used for the transformer comprises a magnetic core, a coil and a framework body, wherein the coil is wound around the framework body, the magnetic core is fixed on the framework body through adhesive tape, a secondary pin is arranged on one side of the lower end of the framework body, the other side of the lower end of the framework body is connected with the magnetic core, and an insulating layer is arranged between the secondary pin and the magnetic core. The widened framework used for the transformer has the advantages that the creepage distance between the magnetic core and the secondary pin is increased when the transformer is used, safety performance of a product is improved, the probability of a fly wire adding procedure on the secondary side of the transformer is reduced, production efficiency is improved, and production cost is reduced for manufacturers.
Description
Technical field
The utility model relates to the electronic accessory parts field, is specifically related to a kind of skeleton of widening for transformer.
Background technology
On electric, to the requirement of minimum creep distance, relevant with the voltage between two conductive components, with insulating material anti-, to let out the trace index relevant, relevant with the class of pollution of electrical equipment environment of living in.Minimum creep distance is made to restriction, is in order to prevent that, between two electric conductors, creepage phenomenon appears in the pollutant that may occur by the insulating material surface.Creepage distance is in utilization, and the shortest insulation distance between charged two conductors that install is greater than the minimum creep distance of permission.When definite electric clearance and creepage distance, should consider rated voltage, pollution situation, insulating material, surface configuration, locality, bear multiple service condition and the environmental factors such as voltage time length, this setting is all arranged in advanced equipment and product standard.
Existing EE13 transformer framework wire wrap terminal is shorter, in the transformer use procedure, the elementary creepage distance with time inter-stage is short, in order to increase the elementary and secondary creepage distance of transformer, factory's daily life of a family adopts secondary fly line/shift-up wall technology, increase cost and time of delivery have been caused like this, the reduction of production efficiency.
The utility model content
For the problems referred to above, the utility model aims to provide the skeleton of widening for transformer that a kind of creepage distance is larger.
For realizing this technical purpose, scheme of the present utility model is: a kind of skeleton of widening for transformer, comprise magnetic core, coil, skeleton, coil winding is on skeleton, magnetic core is fixed on skeleton by adhesive tape, described skeleton lower end one side is provided with secondary PIN pin, and skeleton lower end opposite side is connected with magnetic core, between secondary PIN pin and magnetic core, is provided with insulating barrier.
As preferably, described skeleton is hollow structure.
As preferably, the spacing of described secondary PIN pin and magnetic core is 8mm.
The beneficial effects of the utility model, transformer in use, has increased the creepage distance between magnetic core and secondary PIN pin, make product that higher security performance be arranged, reduced transformer secondary output possible add the fly line program, improved production efficiency, reduced the production cost of producer.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The profile that Fig. 2 is skeleton of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, 2, specific embodiment described in the utility model is a kind of skeleton of widening for transformer, comprise magnetic core 1, coil 3, skeleton 2, coil 3 is wrapped on skeleton 2, magnetic core 1 is fixed on skeleton 2 by adhesive tape, more whole immersion oil, and described skeleton 2 lower end one sides are provided with secondary PIN pin 4, skeleton 2 lower end opposite sides are connected with magnetic core 1, between secondary PIN pin 4 and magnetic core 1, are provided with insulating barrier 5.Can increase magnetic core and secondary PIN pin spacing by insulating barrier, realize cost, production efficiency improves.
In order to make transformation light, be easy to heat radiation, described skeleton 2 adopts hollow structure.
In design, magnetic core and secondary PIN pin spacing are increased to 8mm, subduction is around the about 1.0mm of three-layer insulated wire diameter on secondary PIN stitch, the elementary creepage distance with time inter-stage of finished product transformation is 7.0mm, be greater than safety and require 6.5mm, the spacing at the edge that described secondary PIN pin 4 and magnetic core 1 are nearest is 8mm.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection range of technical solutions of the utility model.
