[0014] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0015] like Figure 1-Figure 2 As shown, a transformer coil skeleton comprises a skeleton body 1 and pins 7, wherein the skeleton body 1 comprises a winding drum 2, and the winding drum 2 is used for winding a coil;

[0016] The two ends of the winding drum 2 are respectively provided with limit plates 3, which limit the positions of the two ends of the coil;

[0017] The lower ends of the limit plates 3 are provided with wiring blocks 4, and wire separators 5 are evenly distributed below the wiring blocks 4. Plug holes 6 are respectively provided below the wire separators 5, and pins 7 are provided in the plug holes 6. The pins 7 can be inserted into the plug holes 6. When customers have different needs, different pin arrangement methods can be selected; if customers have separate needs later, they can also change the position of the pins 7 by themselves;

[0018] The coil wire can be wound around pin 7 after being led out and fixed by welding;

[0019] A winding post 8 is provided at the outward end of the wire separator 5, and a wire groove 9 is provided between two adjacent wire separators 5. After the coil wire is led out, it first passes through the wire groove 9, and then is fixed on the winding post 8, and then is wound onto the pin 7, so that the lead wire is firmly wound and easy to be automatically wound.

[0020] Furthermore, auxiliary blocks 10 are provided on the wire partitions 5 at both ends of the junction block 4. The auxiliary blocks 10 are used to assist the wires to enter the adjacent wire slots 9 to prevent the lead wires from slipping out of the wire slots 9 and causing a short circuit.
