[0033] To improve the reliability of the PQ-type transformer 10 during use, in one embodiment, as Figure 1 and Figure 3 shown, the second connection pins 212 are equally spaced from each other. In this embodiment, by equally spacing the second connection pins 212 on the second fixing member 210, the uniformity of the layout of the second connection pins 212 can be improved, the stability of electrical transmission when the second winding is connected to the second connection pins 212 can be enhanced, and problems such as poor contact or short circuit caused by inconsistent spacing between the second connection pins 212 can be avoided, thereby improving the reliability of the PQ-type transformer 10 during use.

[0034] In order to further increase the flexibility and versatility of the PQ type transformer 10, in one embodiment, as Figure 2 and Figure 4 As shown, the third fixing member 400 is further provided with a plurality of fourth wiring pins 404, and the distance between the fourth wiring pin 404 and the first wiring pin 203 is smaller than the distance between the third wiring pin 403 and the first wiring pin 203.

In this embodiment, when the second winding is connected to the first wiring pin 203, the second winding is placed in the first placement groove 201, and the second winding abuts against the side wall of the first placement groove 201. Through the above arrangement, the position of the second winding on the first fixing member 200 can be limited, so that the second winding can be better aligned with the first wiring pin 203, which is convenient for the second winding to be connected to the first wiring pin 203. At the same time, the first placement groove 201 can also provide a supporting function, so that the connection between the second winding and the first wiring pin 203 is more stable.

In this embodiment, since the width of the second placement grooves 202 is greater than the width of the first placement grooves 201, the second placement grooves 202 can provide positioning and support for second windings of different specifications to meet the connection requirements of second windings of different specifications with the first wiring pins 203. Among them, staggering each of the first placement grooves 201 and each of the second placement grooves 202 can avoid misalignment when the second winding is connected to the first wiring pin 203, thereby improving the stability when the second winding is connected to the first wiring pin 203.

[0037] In order to improve the stability when the first winding is connected to the third connection pin 403, in one embodiment, as Figure 2 and Figure 4 shown, a plurality of third placement grooves 401 are formed in the third fixing member 400, and each of the third placement grooves 401 is aligned with a corresponding third connection pin 403.

Through the above arrangement, the position of the first winding on the third fixing member 400 can be restricted, so that the first winding is aligned with the third connection pin 403, which is convenient for the connection between the first winding and the third connection pin 403. At the same time, the third placement groove 401 can also provide a supporting function, thereby making the connection between the first winding and the third connection pin 403 more stable.

[0038] In order to improve the stability when the first winding is connected to the fourth connection pin 404, in one embodiment, as Figure 2 and Figure 4 shown, the third fixing member 400 is further provided with a plurality of fourth placement grooves 402, each of the fourth placement grooves 402 is aligned with a corresponding fourth connection pin 404, and the fourth placement grooves 402 and the third placement grooves 401 are arranged in a staggered manner. In this embodiment, through the fourth placement groove 402, the first winding can be limited and supported, and the stability of the connection between the first winding and the fourth connection pin 404 can be improved. At the same time, by arranging the fourth placement grooves 402 and the third placement grooves 401 in a staggered manner, the third connection pins 403 and the fourth connection pins 404 can be limited, so that each third connection pin 403 can be aligned with a third placement groove 401 and each fourth connection pin 404 can be aligned with a fourth placement groove 402, avoiding misalignment when the first winding is connected to the third connection pin 403 or the fourth connection pin 404, so as to improve the overall safety performance of the PQ type transformer 10.

[0039] In order to improve the stability when the second winding is connected to the second connection pin 212, in one embodiment, as Figure 1 and Figure 3 shown, a plurality of fifth placement grooves 211 are formed in the second fixing member 210. In this embodiment, when the second winding is connected to the second connection pin 212, the second winding is placed in the fifth placement groove 211, and the fifth placement groove 211 provides limitation and support for the second winding, so that the second winding can be accurately aligned with the second connection pin 212 and a stable connection can be formed between the two.

[0040] In order to form a stable connection between the first magnetic core 300 and the winding skeleton 100, in one embodiment, as Figure 1 andFigure 3 As shown, two first clamping blocks are spaced apart on the first end of the winding skeleton 100, and the two first clamping blocks are respectively abutted against both sides of the first magnetic core 300. In this embodiment, by respectively abutting the two first clamping blocks against both sides of the first magnetic core 300, a firm connection is formed between the first magnetic core 300 and the winding skeleton 100, which can prevent the first magnetic core 300 from shifting during use, so as to improve the overall stability and reliability of the PQ type transformer 10.

[0041] In order to form a firm connection between the second magnetic core 310 and the winding skeleton 100, in one embodiment, as Figure 1 and Figure 3 shown, two second clamping blocks are spaced apart on the second end of the winding skeleton 100, and the two second clamping blocks are respectively abutted against both sides of the second magnetic core 310. In this embodiment, by respectively abutting the two second clamping blocks against both sides of the second magnetic core 310, a firm connection is formed between the second magnetic core 310 and the winding skeleton 100, which can prevent the second magnetic core 310 from shifting during use, so as to improve the overall stability and reliability of the PQ type transformer 10.
