Abstract
The utility model discloses a transformer lead soldering structure based on the medium frequency induction heating principle. The transformer lead soldering structure based on the medium frequency induction heating principle comprises a first lead and a second lead which is connected with the first lead in a lap joint mode. The transformer lead soldering structure is characterized in that copper soldering flakes for soldering are arranged at the position of the lap joint between the first lead and the second lead in a clamped mode, and the end, connected with the second lead in the lap joint mode, of the first lead and the end, connected with the first lead in the lap joint mode, of the second lead are fastened through copper wires. According to the technical scheme, soldering between the leads is well achieved according to the medium frequency induction heating principle; compared with a traditional gas soldering mode, the transformer lead soldering structure cannot generate a naked flame, and therefore a higher safety factor is achieved; due to the fact that the copper soldering flakes are evenly distributed between the first lead and the second lead, solder joints and solder sides are even, and have better electrical conductivity; in the soldering process, a user only needs to place a medium-frequency induction heater at the position of the lap joint between the first lead and the second lead, operation is easy and convenient, and soldering efficiency is greatly improved.
Description
Technical field
The utility model belongs to transformer technology field, particularly relates to a kind of welding transformer lead wire structure based on Frequency Induction Heating principle.
Background technology
At present, Transformer Winding adopts wire coiling more, then adopts the mode of oxygen, acetylene welding to weld in wire and wire or wire and lead-in wire copper bar, completes connection between each winding and the input of electric energy by the welding of lead-in wire.Finding by practice, there is following defect in traditional this welding manner: one, have naked light when adopting the welding manner of oxygen, acetylene welding, therefore very easily the eyesight to operating personnel or skin damage; Two, welding process complexity, inefficiency; Three, welded workpiece be easily out of shape and the region of thermal impact larger, cannot meet the needs of high-accuracy welding.
Utility model content
The technical problems to be solved in the utility model is: the welding transformer lead wire structure based on Frequency Induction Heating principle that a kind of coefficient of safety is good, welding efficiency is high, welding quality is good is provided.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A welding transformer lead wire structure based on Frequency Induction Heating principle, comprises the first wire and the second wire with the first wire overlap joint; Accompany the brazing sheet of welding use in the lap-joint of described the first wire and the second wire; The bond end of described the first wire and the second wire is undertaken fastening by copper wire.
As optimal technical scheme, the utility model has also adopted following technical scheme:
On the first wire of described lap-joint both sides and the second wire, be wound with defensive asbestos cloth.
Advantage and the good effect that the utlity model has are: one, by adopting technique scheme, the utility model has been realized the Welding Problems between wire well according to Frequency Induction Heating principle, compared with traditional gas welding mode, the utility model can not produce naked light, therefore has better coefficient of safety; Two,, because the brazing sheet in the utility model is uniformly distributed between the first wire and the second wire, therefore solder joint, solder side are more even, electric conductivity is better; Three, the utility model, in welding process, only needs medium frequency induction heater to be placed in the lap-joint of the first wire and the second wire, simple to operation, has greatly improved the efficiency of welding; Four,, because the utility model is wound with defensive asbestos cloth in the both sides of the first wire and the second wire lap-joint, therefore can prevent well that the insulating barrier on wire is damaged.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, the first wire; 2, the second wire; 3, brazing sheet; 4, copper wire; 5, asbestos cloth; 6, medium frequency induction heater.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of welding transformer lead wire structure based on Frequency Induction Heating principle, comprising: the first wire 1, the second wire 2, brazing sheet 3, copper wire 4 and asbestos cloth 5; Wherein: one end of the first wire 1 overlaps mutually with one end of the second wire 2, and the degree of depth of overlap joint is generally 20～30mm; Brazing sheet 3 is sandwiched in the lap-joint of the first wire 1 and the second wire 2; Copper wire 4 is around in the skin of the first wire 1 and the second wire 2 lap-joints, for carrying out fastening to lap-joint; In the time welding, the first wire 1 and the second wire 2 lap-joints are placed in to medium frequency induction heater 6 annexes, medium frequency induction heater 6 produces the induction field of intermediate frequency, now, produce vortex flow in the interior meeting of brazing sheet 3, under the effect of vortex flow, brazing sheet 3 melts and then realizes the welding of the first wire 1 and the second wire 2; In this process, can not produce naked light, therefore there is higher coefficient of safety, meanwhile, because brazing sheet 3 is heated more evenly, the speed of its each point position fusing is consistent, therefore has better welding quality.
In order to prevent in welding process, the heat energy that medium frequency induction heater 6 produces causes damage to lap-joint both sides the first wire 1 and the second wire 2 outer insulation, as preferably, this specific embodiment is wound with defensive asbestos cloth 5 on the first wire 1 of described lap-joint both sides and the second wire 2.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
