[0022] The present invention will be further described below with reference to the accompanying drawings: Example

[0023] Reference Figure 1-3 A miniature transformer for a load control terminal includes a transformer body 1, wherein: a plurality of groups of S-end leads 5 are uniformly led out from one side of the transformer body 1, and a plurality of groups of P-end leads 6 are uniformly led out from the other side of the transformer body 1; the transformer body 1 is provided with a quick-release structure so as to support the transformer body 1 through the quick-release structure and ensure the stability of the transformer body 1, and the transformer body 1 is detachably fixedly connected to related equipment through the quick-release structure; and a wiring ring 7 is fixedly installed at the outer end of each P-end lead 6.

[0024] A positioning groove 1 2 is provided on one side of the transformer body 1. The positioning groove 1 2 is provided so that the mounting surface of the transformer body 1 can be positioned when the transformer body 1 is connected to the quick-release structure for installation. Positioning grooves 2 3 are provided on both end surfaces of the transformer body 1. The positioning grooves 2 3 are provided so that the end surface of the transformer body 1 can be positioned when the transformer body 1 is connected to the quick-release structure for installation. The positioning grooves 2 3 are connected to the positioning groove 1 2 in a U shape so that the transformer body 1 can be disassembled and assembled with the quick-release structure. The transformer body 1 is installed on the quick-release structure by plugging and unplugging through the positioning grooves 1 2 and 2 3.

[0025] A card slot 4 is provided on each side of the transformer body 1 opposite to the positioning slot 1 2, and the card slot 4 is connected to the corresponding positioning slot 2 3; the transformer body 1 is connected to the quick-release structure through the card slot 4 to ensure the stability of the transformer body 1 after being installed on the quick-release structure.

[0026] The quick-release structure includes a positioning fixing seat 8, and an elastic plate 9 is fixedly installed at both ends of the positioning fixing seat 8. The two elastic plates 9 are arranged in a U-shape with the positioning fixing seat 8, so that the mutual inductor body 1 can be supported and positioned by the positioning fixing seat 8 and the elastic plate 9; the positioning fixing seat 8 is clamped with the positioning groove 1 2; the elastic plate 9 is clamped with the corresponding positioning groove 2 3.

[0027] An integrated clamping block 10 is provided on the inner side of the top of each of the two elastic plates 9.
