According to the present invention, the second main body portion 60 is provided with the primary coil of the transformer 1, and the secondary coil of the transformer 1 is provided in the first main body portion 20. For convenience of explanation, the primary coil of the transformer 1 is referred to as a second coil 15, and the secondary coil of the transformer 1 is referred to as a first coil 10.
The first coil body member 32 is formed integrally with the first cover 34 and is molded of an insulator material that does not conduct electricity.
The base portion 40, which is provided with the mounting portion 44 at the inner side thereof and is connected with the coil mounting portion 30, and the second body portion 60, which is provided with the second coil 15, is detachably provided at the mounting portion 44, and may be formed in various shapes within the technical idea.
The base 40, provided with a mounting portion 44 on the inside, includes: a base main body 42, a first guide protrusion 46, and a first connecting pin member 49.
The inside of the base body 42 is provided with a groove portion, i.e., a mounting portion 44, for attaching and detaching the second body portion 60, and the upper side of the base body 42 is connected to the coil mounting portion 30.

When the first coil 10 connected with the first connection pin member 49 is moved in a lateral direction, it is caught by the extension protrusion member 48, and thus its movement is restricted, thereby enabling a structure in which the first coil 10 is connected to the first connection pin member 49 to be more stable.
The protrusion main body 47 extends in a lateral direction of the base main body 42, and the extension protrusion member 48 extends downward from an end of the protrusion main body 47.
Fig. 3 to 5 are perspective views of a transformer 1 according to an embodiment of the present invention. As shown in fig. 3 to 5, the extension portion 50, which extends from the first body portion 20 and faces the side of the magnetic core member 70, may be changed into various shapes within the technical idea. And an extension part 50 connected to both sides of the first cover part 34, which protrudes along an upper side of the first cover part 34. Since the extended portions 50 are provided at both sides of the magnetic core member 70 of the first cover portion 34, the magnetic core member 70 is caught by the extended portions 50, thereby restricting the magnetic core member from moving laterally.
The extension 50 according to one embodiment, comprises: first extension parts 52 extending from the first body parts 20 located at both sides of the magnetic core member 70 and facing the magnetic core member 70; and a second extension portion 54 protruding in a lateral direction of the first extension portion 52.

And is disposed on both sides of the magnetic core member 70 of the first cover portion 34.
The length of the first extension portion 52 protruding from the first cover portion 34 of the first body portion 20 is a first length D1, the thickness of the magnetic core member 70 adjacent to the first body portion 20 is a second length D2, and the first length D1 is formed to be less than or equal to the second length D2. That is, the first length D1 is smaller than the second length D2, and thus the height of the first extension 52 protruding from the upper side of the first cover part 34 is formed to be lower than or equal to the height of the magnetic core member 70 disposed in a state adjacent to the first cover part. Therefore, when the magnetic core member 70 slides in the horizontal direction of the first cover portion 34, the magnetic core member 70 is caught by the first extending portion 52 and movement is restricted.
In one embodiment, the second extension 54 extends horizontally or laterally from an end of the first extension 52. The first extension 52 and the second extension are formed integrally with the first cover 34.
The first coil 10 according to one embodiment is wound on the outer side of the first coil body member 32 and the outer side of the first extension portion 52 such that the length in the vertical direction is increased, and thus the wound first coil 10 has a smaller outer diameter and an increased area of the first coil 10 adjacent to the air. Therefore, the heat generated by the first coil 10 is rapidly dissipated, so that the temperature characteristic of the first coil 10 can be improved.
In one embodiment, the first coil 10 wound on the outside of the first coil body member 32 and the outside of the first extension portion 52 has a smaller coil height increasing width than a conventional coil wound only on the outside of the first coil body member 32, and thus, the same effect can be obtained even with a small number of coils as compared with the prior art, so that the production cost can be reduced.
The designed safe distance a of the first coil 10 and the second coil 15 is a measurement value of the designed safe distance a, which is a shortest distance of an imaginary line when the imaginary line is extended along a surface of a member located between the first coil 10 and the second coil 15. The design safety distance a is an essential factor in the design of the transformer 1, and particularly, the design safety distance a between the first coil 10 and the second coil 15 needs to be larger than a predetermined distance.
According to the present invention, the transformer 1 is inserted into one side (refer to the left side in fig. 2) of the second coil 15 inside the first body 20, and is shielded by the side of the first body 20, thereby excluding the first coil 10 and the second coil 15 when measuring the designed safety distance.
In addition, the design safe distance a between the second coil 15 located at the inlet side (refer to the right side of fig. 2) of the opening of the first body part 20 and the first coil 10 disposed adjacent thereto is the shortest safe distance, and thus this distance is measured to determine whether the design safe distance a is satisfied. The design safety distance a according to one embodiment is an imaginary line extending from the first coil 10 to the second coil 15 along the upper side of the base body 42 after forming a path winding the shape of the end of the base body 42 in the other side (refer to the right side in fig. 2) direction.
Since the outer diameter of the first coil 10 wound outside the first coil body member 32 becomes small, the design safety distance a increases.
As shown in fig. 1 and 2, the second coil 15 is wound around the second body portion 60 and detachably provided at the mounting portion 44, and may be formed in various shapes within the technical idea. The second body portion 60 according to one embodiment includes: a second coil body member 61, a second cover 62, and a second support 63.

As shown in fig. 4, second guide protrusions 65, which are formed in the same number as the second connecting pin members 66, extend in the horizontal direction from the end of the second support body 64. In addition, the second coil 15 wound outside the second coil body member 61 can be stably wound outside the second coil body member 61 because it is located between the second cover part 62 and the second support body 64.
As shown in fig. 1, the magnetic core member 70 penetrates the first body portion 20 and the second body portion 60, and is disposed outside the first body portion 20.

As shown in fig. 7 and 8, the first coil 10 is wound around the outside of the first body portion 20. As shown in fig. 3, the second coil 15 is wound around the second body 60.
The first coil 10 is connected to the first connecting pin member 49 in a state of being wound around the first guide protrusion 46, thereby preventing a phenomenon in which a short circuit is generated by the first coil 10 connected to the first connecting pin member 49 moving to the adjacent first connecting pin member 49 or first coil 10.
As shown in fig. 1 and 2, the core member 70 is disposed outside the coil mounting portion 30 in a state where the second body portion 60, to which the second coil 15 has been fitted, is inserted inside the mounting portion 44 of the base 40.

In addition, the first coil 10 is wound outside the first coil body member 32 and the first extension portion 52, so that the coil height of the first coil 10 reaches a length increasing from the first coil body member 32 to the first extension portion 52, thereby increasing the heat radiation area of the first coil 10 to improve the temperature characteristics of the first coil 10. Further, since the winding width of the first coil 10 is reduced, the amount of use of the first coil 10 is reduced, so that the production cost can be saved. In addition, the present invention can increase the design safety distance by winding the first coil 10 around the first coil main body member 32 and the first extension portion 52, so that the coil height of the first coil 10 is equivalent to the length degree increased to the first extension portion 52, and the width of the first coil is reduced, thereby improving the design freedom.
