Abstract
The utility model provides a coil framework structure used for a transformer, comprising a coil framework, a transformer coil and a magnetic core; wherein, the coil framework is a hollow spiral-shaped framework which is wound by an insulation pipe; the dental width of the hollow spiral framework is the thickness of the transformer coil lead; the dental distance of hollow spiral framework is the sum of the thickness of the transformer coil lead and the insulation clearance of the coil inter-turn; the transformer coil is wound to be a spring shape which has the same dental distance as the hollow spiral framework; the transformer coil is screwed on the hollow spiral framework; the magnetic core is inserted in the hollow spiral framework and the transformer coil. During the installation process, the transformer coil is screwed along the opening direction of the hollow spiral framework; the whole transformer coil is screwed in the dental width which is formed by the insulation pipe and arranged in the hollow spiral framework; the magnetic core is arranged in the hollow spiral framework and the transformer coil or the chamber of the round pipe, so as to wholly assemble the coil framework structure of the transformer.
Description
Technical field:
The utility model relates to the field transformer in the electric welding machine, especially a kind of cored screw type transformer coil skeleton structure.
Background technology:
Transformer device structure in the past is divided into the insulation system between coil and magnetic core, the insulation system between coil turn, and three parts of the fixed structure of coil are formed, when work, three structures need be used in combination, and complex structure own, be unfavorable for producing.
The utility model content:
Technical problem to be solved in the utility model is that a cored screw type coil rack that adopts insulating material to make is fixed transformer coil, thereby reach fixed coil and solve insulation between magnetic core and the insulation between coil turn, help the heat radiation of transformer coil like this, also be beneficial to produce and install, reduced material cost and manufacturing cost simultaneously.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of coil skeleton structure of transformer, comprise coil rack, transformer coil and magnetic core, it is characterized in that: described coil rack is a cored screw shape skeleton that is turned to by insulated tube, the tooth of described cored screw shape skeleton is wide to be the thickness of transformer coil lead, and the tooth of described cored screw shape skeleton is apart from the gap that adds coil turn-to-turn insulation for the thickness of transformer coil lead; Described transformer coil winding becomes the spring-like with the identical tooth distance of described cored screw shape skeleton.
Described transformer coil is screwed on the described cored screw shape skeleton, and described magnetic core is inserted in described cored screw shape skeleton and the described transformer coil.
The two ends of described cored screw shape skeleton are connected with terminal block.
The internal diameter of described transformer coil is identical with the path of described cored screw shape skeleton.
Described transformer coil winding is on a pipe.
When mounted, transformer coil is screwed in along cored screw shape skeleton rotation opening direction, whole transformer coil all screw in tooth between the cored screw shape skeleton that constitutes by insulated tube wide in, magnetic core is placed in cored screw shape skeleton and the transformer coil or among the cavity of pipe, integral body has been formed the coil skeleton structure of transformer.
The beneficial effects of the utility model are simultaneously three separated structures to be realized on a main body, promptly simplify the structure and have reduced cost.
Description of drawings:
Fig. 1 is that the utility model is formed structural representation.
Fig. 2 is the utility model mounted configuration schematic diagram.
Among the figure: 1-cored screw shape skeleton, 11-insulated tube, 2-transformer coil, 21-pipe, 22-lead, 23-thread groove, 3-magnetic core, 4-terminal block.
Embodiment:
Below in conjunction with drawings and the specific embodiments structure of the present utility model and operation principle are done further introduction.
As shown in Figure 1, a kind of coil skeleton structure of transformer, comprise coil rack, transformer coil 2 and magnetic core 3, the cored screw shape skeleton 1 that coil rack is turned to by insulated tube 11, the insulated tube 11 at cored screw shape skeleton 1 two ends tangentially extends out, and the insulated tube 11 that two ends extend out is welded with terminal block 4.The effect of terminal block 4 is in order to the fixed coil skeleton on the one hand, makes things convenient for transformer coil 2 to be connected with power line on the other hand.
The insulated tube of coiling cored screw shape skeleton 1 is a flat, and the tooth of the cored screw shape skeleton 1 that winds up is wide to be the thickness of the lead 22 of coiling transformer coil 2, and tooth adds the gap of coil turn-to-turn insulation apart from the thickness that is the lead 22 of transformer coil 2.Transformer coil 2 adopts lead 22 to turn to spring-like, and its tooth is apart from identical with the tooth distance of cored screw shape skeleton 1.The internal diameter of transformer coil 2 is identical with the path of cored screw shape skeleton 1, is convenient to like this magnetic core 3 is inserted in transformer coil 2 and the cored screw shape skeleton 1.Certainly in order to make transformer coil 2 be convenient to be screwed in the cored screw shape skeleton 1, can be on a pipe 21 with transformer coil 2, transformer coil 2 has certain rigid like this, convenient rotation.Transformer coil 2 on the pipe 21 after, just have thread groove 23 between circle and the circle, thread groove 23 teeth apart from the tooth of cored screw shape skeleton 1 apart from identical.
As shown in Figure 2, transformer coil 2 is screwed in along cored screw shape skeleton 1 rotation opening direction, whole transformer coil 2 all screw in tooth between the cored screw shape skeleton 1 that constitutes by insulated tube 11 wide in, magnetic core 3 is placed in cored screw shape skeleton 1 and the transformer coil 2 or among the cavity of pipe 21, integral body has been formed the coil skeleton structure of transformer.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
