Description

Technical Field

[0001] The utility model belongs to the technical field of transformer wire core skeletons and relates to a transformer wire core stabilizing skeleton. Background Art

[0002] The transformer skeleton is a structure used to wind the wire core to form a coil. In a double-winding coil, a partition is usually provided in the middle of the transformer skeleton, and the transformer skeleton is separated into a primary winding slot and a secondary winding slot by the partition. The double-winding structure is formed by winding the wire core in the primary winding slot and the secondary winding slot.

[0003] However, the existing partitions outside the transformer coil are fixedly arranged, and the axial position of the partitions relative to the transformer frame cannot be adjusted, which results in the fixed axial lengths of the primary winding slots and the secondary winding slots. However, for coil assemblies with different model requirements, the number of windings of the primary winding and the secondary winding will change, that is, the axial length of the wire core after winding will also change. The existing transformer frame cannot meet the different winding number requirements and adjust the axial position of the partition.

[0004] Therefore, in view of the above-mentioned defects of the existing transformer skeleton, the utility model discloses a transformer core stabilizing skeleton. Utility Model Content

[0032] The partition plate 3 is sleeved on the outside of the skeleton body 1, and a spiral portion corresponding to the spiral groove 4 on the outer wall of the skeleton body 1 is provided on the inner hole wall of the partition plate 3. By rotating the partition plate 3, the partition plate 3 is moved along the axial direction of the skeleton body 1 to adjust the distance between the partition plate 3 and the pin seats 2 at the left and right ends. A primary winding groove and a secondary winding groove are formed between the partition plate 3 and the pin seats 2 at the left and right ends. By axially moving the partition plate 3, the axial lengths of the primary winding groove and the secondary winding groove can be adjusted, so that the primary winding groove and the secondary winding groove can meet the winding requirements of different numbers of turns.

[0033] After the axial position adjustment of the partition 3 is completed, the pin seat 2 can be installed on the left and right ends of the skeleton body 1. A plurality of pins 5 are linearly arranged at the bottom of the pin seat 2, and the pins 5 include long pins and short pins.

[0034] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0035] Embodiment 2:

[0036] A transformer core stabilizing skeleton is improved on the basis of embodiment 1, such as Figure 5 As shown, the partition 3 includes a partition body 31 and a mounting sleeve 32 . The mounting sleeve 32 is spirally mounted on the outside of the skeleton body 1 , and the partition body 31 is arranged on the outer side of the mounting sleeve 32 .

[0037] The inner hole wall of the mounting sleeve 32 is provided with a spiral portion that is spirally connected with the spiral groove 4. Through the spiral cooperation between the spiral portion and the spiral groove 4, when the mounting sleeve 32 is rotated, the mounting sleeve 32 can be driven to move along the axis of the skeleton body 1. The outer surface of the mounting sleeve 32 is welded with a partition body 31, and a primary winding groove and a secondary winding groove are formed between the partition body 31 and the pin seats 2 at the left and right ends. By adjusting the axial position of the mounting sleeve 32, the axial length of the primary winding groove and the secondary winding groove can be adjusted to meet the winding requirements of different numbers of turns.

[0038] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0039] Embodiment 3:

[0040] A transformer core stabilizing skeleton, improved on the basis of embodiment 1 or 2, such as Figure 4 and Figure 5 As shown, a partition body 31 is disposed at both left and right ends of the outer side surface of the mounting sleeve 32 , a fastening groove 33 is disposed between the partition bodies 31 at the left and right ends, and a fastener 34 is disposed in the fastening groove 33 .

[0041] At least two groups of fastening grooves 33 are evenly spaced along the circumferential direction on the outer surface of the mounting sleeve 32 in the area between the partition bodies 31 at the left and right ends, and fasteners 34 are arranged inside the fastening grooves 33. When the fasteners 34 are loosened, the mounting sleeve 32 can be rotated so that the mounting sleeve 32 moves axially relative to the frame body 1. When the mounting sleeve 32 moves axially into position, the fastener 34 is locked, and at this time, one end of the fastener 34 presses against the outer side surface of the frame body 1 through the fastening groove 33, thereby fixing the axial position of the mounting sleeve 32.

[0042] Furthermore, the fastener 34 includes a fastening hoop 341 and a fastening pressure block 342. The fastening pressure block 342 is arranged inside the fastening groove 33, and one end of the fastening pressure block 342 contacts the outer side of the skeleton body 1; the fastening hoop 341 is wrapped around the outer side of the fastening pressure block 342.

[0043] The fastening block 342 is arranged inside the fastening groove 33, one end of the fastening block 342 contacts the outer side of the skeleton body 1, and the other end of the fastening block 342 contacts the fastening clamp 341. When the fastening clamp 341 is loosened, the fastening block 342 does not press the outer side of the skeleton body 1 tightly, and the installation sleeve 32 can move axially relative to the skeleton body 1. When the fastening clamp 341 is tightened, the fastening block 342 is clamped toward the skeleton body 1 by the fastening clamp 341, so that the fastening block 342 presses the outer side of the skeleton body 1 tightly, thereby realizing the axial fixation of the installation sleeve 32.

[0044] The other parts of this embodiment are the same as those of Embodiment 1 or 2, and thus will not be described in detail.

[0047] By docking the first card slot 100 and the second card block 200, the pin seat 2 is conveniently positioned and installed at the end of the frame body 1. At the same time, by the circumferential clamping of the first card slot 100 and the second card block 200, the circumferential limit of the pin seat 2 is achieved to prevent the pin seat 2 from rotating circumferentially, thereby ensuring the stability of the entire transformer core stabilization frame.

[0048] Furthermore, a wire core limiting flange 6 is provided at the edge of one end of the skeleton body 1 away from the skeleton body 1, and a primary winding groove or a secondary winding groove is formed between the wire core limiting flange 6 and the partition 3, and the outer diameters of the wire core limiting flange 6 and the partition 3 are both larger than the outer diameter of the skeleton body 1, which can effectively limit the axial position of the wire core wound outside the skeleton body 1 to prevent the wire core from moving.

[0050] Embodiment 5:

A first locking hole is provided on the bottom surface of the first slot 100, and a second locking hole is provided on the second clamping block 200 at a position corresponding to the first locking hole, and locking pins are inserted into the first locking hole and the second locking hole.

[0052] After the first card slot 100 and the second card block 200 are correspondingly engaged, the first locking hole and the second locking hole are aligned, and the locking pin can be inserted into the first locking hole and the second locking hole to achieve a fastening connection between the first card slot 100 and the second card block 200, thereby preventing the pin seat 2 from loosening and falling off from the end of the skeleton body 1.

[0053] The other parts of this embodiment are the same as any one of Embodiments 1-4, so they are not described again.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form.
