Description

Lead-out structure of transformer coil

Technical Field

The utility model belongs to the technical field of the transformer, specifically speaking, the utility model relates to a transformer coil wire leading-out structure.

Background

The lead-out method of the lead of the transformer coil usually adopts a direct lead-out method or a reverse lead-out method. As shown in fig. 3, the direct lead-out method is adopted, and after the lead at the bottom layer of the coil is led out, the lead is very close to the iron core of the transformer, which is not beneficial to welding of an external lead and a lead-out head; as shown in fig. 4, by adopting the reverse head leading-out method, the leading-out wire needs to pass through the insulating sleeve and then is pressed in other layers of windings to be led out, so that the coil assembly can be separated from the iron core, but the leading-out head treatment in the operation process is troublesome, and the efficiency is low.

In summary, the lead-out method of the existing transformer coil is prone to interference between the lead-out head and the iron core when a user connects a wire, which affects the connection, and the reverse lead-out method adopted to solve the problem at present has low efficiency. And the leading-out heads of the transformer coils are disordered and are not tidy and beautiful.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a structure is drawn forth to transformer coil wire, the purpose improves transformer coil wire and draws forth head treatment effeciency.

In order to realize the purpose, the utility model discloses the technical scheme who takes does: the lead-out structure of the transformer coil comprises a soldering lug and an insulating isolation plate which are arranged on the transformer coil, the soldering lug is connected with the outgoing line of the coil winding in a welding mode, and the insulating isolation plate is provided with a threading hole through which the outgoing line passes.

The soldering lugs are arranged in a plurality, and all the soldering lugs are distributed at two opposite ends of the transformer coil.

Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.

As shown in fig. 1 and fig. 2, the utility model provides a structure is drawn forth to 1 wire of transformer coil, including setting up soldering lug 2 and the insulating division board 3 on transformer coil 1, soldering lug 2 and coil winding's 4 welded connection of lead-out wire set up the through wires hole 5 that lets lead-out wire 4 pass on the insulating division board 3.

Specifically, as shown in fig. 1 and 2, the tab 2 is provided in plurality, and all the tabs 2 are distributed at opposite ends of the transformer coil 1. The soldering lug 2 is of a rectangular structure, and the soldering lug 2 extends out towards the outer side of the transformer coil 1. All outgoing lines 4 of the coil are led out and then welded on the welding pieces 2 arranged on the outermost layer, finally, the whole transformer coil 1 is subjected to vacuum pressure paint dipping treatment, and the whole structure of the coil after paint dipping forms a protective layer, so that the whole insulation performance of the coil is improved. The method for processing the leading-out heads is simpler, more convenient and faster, the insulating paint layer is formed on the surface of each leading-out head 4, each leading-out head does not need to be independently subjected to insulating treatment, the appearance shape is regular, the radial volume of the coil is reduced, the used insulating materials are reduced, and the process period of winding is shortened.

As shown in fig. 1 and fig. 2, in the present embodiment, a total of six soldering lugs 2 are provided, and all the soldering lugs 2 are symmetrically distributed at two ends of the transformer coil 1.

As shown in fig. 1 and 2, the insulating isolation plate 3 is fixed on the transformer coil 1, the insulating isolation plate 3 is made of insulating materials, the number of the insulating isolation plates 3 is two, the two insulating isolation plates 3 are located between two rows of soldering lugs 2 arranged at two ends of the transformer coil 1, three through holes 5 are formed in the insulating isolation plate 3, the through holes 5 are through holes penetrating through the insulating isolation plate 3 in the plate thickness direction, an outgoing line 4 penetrates out of each through hole 5, each outgoing line 4 is welded with one soldering lug 2, and the insulating isolation plate 3 is located between the outgoing line 4 and the transformer coil 1. The insulating isolation plate 3 is of a rectangular structure.

When the transformer coil 1 with the structure is used, the influence of the coil leading-out head on later-stage wiring is avoided, the appearance of the leading-out head can be ensured, the overall size of the coil is reduced, the processing is simple, the manufacturing cost is low, and the coil leading-out head is simple to treat.
