During the connection process, it can make the signal unimpeded and is faster and more convenient to use. The transformer lead terminal is mainly used to connect the power supply so as to transmit electrical energy from the power supply end to the load end to realize the conversion and transmission of electrical energy.

[0003] According to a publicly disclosed low-voltage lead terminal structure for a dry-type transformer (publication number: CN217035364U), in the above application, the wire pressing plate hingedly arranged on the first copper bar and the second copper bar is fixed by two locking bolts, and wire threading grooves are provided between the first copper bar and the corresponding wire pressing plate, and between the second copper bar and the corresponding wire pressing plate, thereby helping to further improve the convenience and efficiency of wiring the lead terminals.

[0004] However, during actual use of the above-mentioned device, the convenience and efficiency of wiring the lead terminal are improved through the cooperation between the first copper bar and the second copper bar, but the lead terminal cannot provide positioning and guidance during wiring, so that the lack of positioning and guidance of the lead terminal during wiring will reduce the stability during wiring; in view of this, we propose a lead terminal structure that is convenient for wiring.

The elastic force of the spring makes the slider slide inside the slide groove so that the two groups of positioning plates are close to each other to position the connecting wire. When the connecting wire is pulled, the ball rotates to provide guidance for the connecting wire when the length is changed during wiring. After the wiring is completed, the magnetic force between the first magnet block and the second magnet block cooperates to make the two groups of positioning plates attract each other, so that the connecting wire is provided with positioning when wiring, and the connecting wire is supported at the same time, thereby improving the stability of the wiring.

[0017] 2. The lead terminal structure that facilitates wiring is provided with a cross hole to facilitate the connection of the connecting wire through the wiring hole and the lead terminal.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a lead terminal structure for convenient wiring, including a transformer body 1, a lead terminal 2 is arranged on the upper surface of the transformer body, a wiring structure is arranged outside the lead terminal 2, and the wiring structure includes a wiring frame 3, a wiring frame 3 is arranged on the upper surface of the transformer body 1, the bottom of the wiring frame 3 is fixedly connected with the top of a rubber column 4, the outer surface of the rubber column 4 is adapted to the inner surface of the mounting groove 5, a wiring hole 6 is opened on the upper surface of the wiring frame 3, a positioning plate 7 is arranged on the top of the wiring hole 6, the bottom of the positioning plate 7 is fixedly connected with the top of a slider 8, the bottom of the slider 8 is slidably connected to the inside of a slide groove 9, the end of the slide groove 9 is fixedly connected with the end of a spring 10, the end of the positioning plate 7 is fixedly connected with one side of a magnet block 11, the other side of the magnet block 11 is magnetically connected with the side wall of a magnet block 2 12, a rubber pad 13 is arranged outside the magnet block 2 12, the side wall of the rubber pad 13 is opened with a groove 14, and the inner surface of the groove 14 is rotatably connected with the surface of a ball 15.

[0025] In one embodiment of the utility model, a mounting groove 5 is provided on the upper surface of the transformer body 1, and two groups of mounting grooves 5 are provided, and the two groups of mounting grooves 5 are mirror-imaged with the central axis of the wiring frame 3 as the axis of symmetry. The number of wiring holes 6 is equal to the number of lead terminals 2. A slide groove 9 is provided on the upper surface of the wiring frame 3, and a plurality of groups of slide grooves 9 are provided, and the plurality of groups of slide grooves 9 are mirror-imaged with the central axis of each group of wiring holes 6 as the axis of symmetry. The number of positioning plates 7 is equal to the slide groove 9. One end of the spring 10 away from the slide groove 9 is fixedly connected to one side of the slider 8. The spring 10 is located at the end of the slide groove 9 away from the wiring hole 6. The inner surface of the positioning plate 7 is fixedly connected to the side of the rubber pad 13 away from the groove 14. The inner surface of the wiring hole 6 is fixedly connected to the outer surface of the rubber ring 16.
