[0021] In order to make the technical means, creative features, achieving purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figures 1-5As shown in the figure, a coil skeleton for a control transformer includes a coil chassis 1. A limiting snap ring 2 is arranged inside the coil chassis 1. A coil reel 3 is clamped at the upper end of the limiting snap ring 2. Triangular terminal blocks 4 are fixedly installed at the notches at both ends of the coil chassis 1. Welding terminals 5 are fixedly installed at the front end of the triangular terminal blocks 4. The cooperation of the coil chassis 1 and the limiting snap ring 2 with the coil reel 3 makes it more convenient to disassemble and assemble the coil inside the coil skeleton and wind and remove the copper wire on the coil skeleton. The operation method is simpler and more labor-saving, and the coil chassis 1 can separate the coils on the coil skeleton.

[0023] There are two triangular terminal blocks 4 installed, and several welding terminals 5 are installed. The welding terminals 5 are evenly distributed at the front end of the triangular terminal blocks 4. The coil reel 3 includes a reel main body 301, a guide rail opening 302, a rubber sleeve 303, a separating disc 304 and an inner octagonal ring 305. The bent clamping strip at the lower end of the reel main body 301 is snapped into the outer slot of the limiting snap ring 2. The guide rail opening 302 is opened at the position on the outer side of the reel main body 301 at the lower end. There are three guide rail openings 302, and the three guide rail openings 302 are evenly distributed at the position on the outer side of the reel main body 301 at the lower end. The rubber sleeve 303 is fixedly installed on the outer side of the reel main body 301. The separating disc 304 is arranged inside the guide rail opening 302. There are three separating discs 304, and the three separating discs 304 are evenly distributed inside the guide rail opening 302. The inner octagonal ring 305 is fixedly installed at the position inside the reel main body 301 at the upper end.

[0024] It should be noted that the present utility model is a coil skeleton for a control transformer. When in use, the triangular terminal blocks 4 can be welded to the circuit board through the welding terminals 5. Among the coil chassis 1, the limiting snap ring 2 and the coil reel 3, a drill bit can be inserted inside the inner octagonal ring 305 to drive the rotation of the reel main body 301, so that the coil is wound around the outer side of the rubber sleeve 303. The rubber sleeve 303 plays a role in anti-slip. The separating disc 304 can slide inside the guide rail opening 302, and the separating disc 304 plays a role in separating the coils. Both ends of the coil can be connected to the welding terminals 5. By rotating the reel main body 301 in the reverse direction, the coil can be restored to copper wire. Then, pull up the separating disc 304 in the guide rail opening 302 and pull out the reel main body 301 upward, so that the bent clamping strip at the lower end of the reel main body 301 can be withdrawn from the slot on the outer side of the limiting snap ring 2, and then the coil chassis 1 and the coil reel 3 can be disassembled. The cooperation of the coil chassis 1 and the limiting snap ring 2 with the coil reel 3 makes it more convenient to disassemble and assemble the coil inside the coil skeleton and wind and remove the copper wire on the coil skeleton. The operation method is simpler and more labor-saving, and the coil chassis 1 can separate the coils on the coil skeleton.
