Embodiment

[0009] see figure 1 As shown, a small transformer includes an iron core 1 and two pairs of upper and lower clips 2 clamping the iron core 1 , and each pair of clips 2 is connected by stud bolts 3 . The epoxy cloth board is embedded in the iron core 1 and the clip 2 to ensure the insulation of the iron core 1 and the clip 2. The middle part of each clip 2 is respectively welded with a channel steel 5, one end of the channel steel 5 is connected to the side end surface of the clip 2, and the other end stretches to the outside of the iron core 1, and this end of each pair of channel steel 5 is also Connected together by stud bolts 3. After the channel steel 5 is arranged in the middle of the clamp 2, the arching of the middle of the clamp 2 is reduced, so that the middle pair of the clamp 2 can also clamp the iron core 1, so that the middle of the rectangular iron yoke can be clamped without Vibration is generated to prevent the iron core 1 from generating noise due to vibratio...

Abstract

The invention discloses a small-sized transformer. The small-sized transformer comprises an iron core, an upper pair of clamping elements and a lower pair of clamping elements, wherein the upper pair of clamping elements and the lower part of clamping elements are used for clamping the iron core, each pair of clamping elements is connected via a dual-head bolt, a steel channel is welded at the middle of each clamping element, one end of the steel channel is connected with the side end surface of the clamping element, the other end of the steel channel extends to the outer side of the iron core, and the other ends of each pair of steel channels are also connected through a dual-head bolt.

Description

technical field [0001] The invention relates to a small transformer and belongs to the technical field of transformers. Background technique [0002] A commonly used transformer in the prior art uses two clamps to clamp the left and right sides of the iron core respectively, and embeds epoxy cloth boards in the iron core and the clamps to ensure the insulation between the iron core and the clamps, and then tighten the two clamps. The head bolts allow the core to be clamped. The disadvantage of this structure is that the middle part of the clip is slightly arched due to the uneven stress of the stud bolts, or the overtightening of the stud bolts, thereby affecting the clamping of the middle part of the iron yoke. In the actual manufacturing process, the reaction force of the clamp is often reduced by increasing the width of the clamp, so as to ensure that the middle part of the iron yoke can clamp the iron core without vibration and noise. The clip is one of the main stru...
