Description

Technical Field

[0001] The utility model relates to the field of transformer skeletons, in particular to a safety transformer skeleton. Background Art

[0002] The transformer skeleton is a component of the main structure of the transformer. It provides space for the copper wire in the transformer to wind and fixes the magnetic core in the transformer. In the existing patent application with application number CN202321269942.0, a transformer skeleton with multiple pins fixed is proposed. Although its mounting block is convenient to install in the frame, it is also convenient to disassemble, the number of pins can be set according to actual needs, and the pins can be easily replaced separately when they are damaged, which is beneficial to the overall use of the transformer skeleton. However, its mounting block is fixed to the frame by the elastic force of the spring to push the limit block and the moving block. When the spring is vibrated, it is easy to produce expansion and contraction shaking, so that the limit block and the moving block pushed by the spring are also easy to shake, and then the limit block on it is easy to accidentally detach from the limit hole, and finally the mounting block is easy to detach from the frame with the pins. Therefore, the safety of the transformer skeleton is low, so it needs to be improved. Utility Model Content

The transformer drum 1 is fixedly connected to the two frames 2. A mounting groove 6 is opened at the side end of the frame 2, and a plurality of through holes 7 are opened at the upper end of the frame 2. The through holes 7 are connected to the mounting groove 6. A connecting groove 8 is opened at the upper end of the frame 2 and on the inner side of the through holes 7. The detachable pin 3 consists of a mounting block 9 and a pin body 10. The pin body 10 is fixedly installed at one end of the mounting block 9. The mounting block 9 is installed in the mounting groove 6 opened at the side end of the frame 2. A fixing socket 11 is opened on the mounting block 9, and the fixing socket 11 penetrates the mounting block 9 from top to bottom.
