The advantage of this type of transformer frame is that it can automatically wind the frame, saving labor costs and improving production efficiency; but the disadvantage of this type of transformer frame is that it is necessary to increase the size of the frame, such as increasing the length or height of the frame. To increase the distance between the pins and the magnetic core, so that the transformer can meet the national electrical safety laws and regulations (referred to as "safety regulations"), and increasing the size of the bobbin will cause the transformer to be unable to be miniaturized. After the upgrade, the requirements for the electrical clearance and creepage distance of the transformer are also increased, which makes the volume of the transformer need to be further increased
The advantage of this type of transformer frame is that the transformer can meet safety regulations by potting the transformer frame; but the disadvantage of this type of transformer frame is that it cannot automatically wind the magnetic ring, resulting in low production efficiency. In addition, The potting process has high process requirements and high cost, and the reliability of the finished transformer is relatively poor

[0036] refer to figure 1 and figure 2 , the transformer 10 includes a transformer frame 101 , a first winding 102 , a second winding 103 and an insulating tape 104 . Wherein, the transformer frame 101 includes a skeleton 1 and a magnetic core assembly 2, the magnetic core assembly 2 is detachably installed on the skeleton 1, and the first winding 102 and the second winding 103 are respectively wound on the skeleton 1. In this embodiment, The insulating tape 104 is wrapped around the first winding 102 and the second winding 103 to protect the first winding 102 and the second winding 103 .

[0037] Specifically, combined with Figure 3 to Figure 5 , the skeleton 1 has an insertion hole 11 , a first limiting portion 12 , a second limiting portion 13 , a first column portion 14 , a first set of pins 15 and a second set of pins 16 . The first limiting portion 12 and the second limiting portion 13 are respectively connected to both ends of the first column portion 14, and the fi...

[0048] The difference between this embodiment and the first embodiment of the transformer lies in the structural design of the magnetic core assembly 3 . Specifically, such as Figure 9 As shown, the first magnetic core 31 has a third bending part 311 and a fourth bending part 312, the third bending part 311 is installed in the blind cavity of the first limiting part, and the third bending part 311 and the first The second ends of the second column parts 321 of the two magnetic cores 32 are adjacent to each other. The fourth bending portion 312 is adjacent to the third limiting portion 322 of the second magnetic core 32 , and the fourth bending portion 312 is located in the limiting groove of the second limiting portion. In the first direction X1, the projection of the first magnetic core 31 is arranged in an "L" shape. Wherein, the third bending portion 311 , the fourth bending portion 312 and the third limiting portion 322 are all arranged in a flat plate shape.

Abstract

The invention provides a transformer frame and a transformer. The transformer comprises a frame and a magnetic core assembly. The frame is provided with a first limiting part, a second limiting part,a first column part with the two ends connected with the first limiting part and the second limiting part correspondingly, and an inserting hole penetrating through the second limiting part and the first column part. A blind cavity communicated with the inserting hole is formed in the first limiting part; an opening of the blind cavity is formed in the first side wall of the first limiting part; afirst pin group is mounted on the first side wall; a second pin group is mounted on the second side wall of the first limiting part; the first side wall and the second side wall are oppositely arranged; the magnetic core assembly comprises a first magnetic core installed in the blind cavity and a second magnetic core provided with a second column part and a third limiting part; the third limitingpart is connected with the end of the second column part and is adjacent to the first magnetic core; and the second column part is installed in the inserting hole and is adjacent to the first magnetic core. The transformer is provided with the transformer frame, and the transformer and the transformer frame have the advantages of being small in size, meeting safety requirements and being capableof achieving automatic winding.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer frame and a transformer provided with the transformer frame. Background technique [0002] The existing transformer frame mainly has the following two forms: [0003] The first type, the transformer frame consists of a bobbin and a magnetic core. The advantage of this type of transformer frame is that it can automatically wind the frame, saving labor costs and improving production efficiency; but the disadvantage of this type of transformer frame is that it is necessary to increase the size of the frame, such as increasing the length or height of the frame. To increase the distance between the pins and the magnetic core, so that the transformer can meet the national electrical safety laws and regulations (referred to as "safety regulations"), and increasing the size of the bobbin will cause the transformer to be unable to be miniaturized. After the upgrade, t...
