[0020] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0021] The high-voltage trigger transformer comprises a cylindrical magnetic core 1, a secondary coil 2, a primary coil 3, a double-wall inner glue heat shrink tube 4, and an ultra-micro high-voltage wire 5. The cylindrical magnetic core 1 is covered with two layers of double-wall inner glue heat shrink tube 4, and the upper double-wall inner glue heat shrink tube 4 is used to separate the secondary coil 2 and the primary coil 3, that is, the inner double-wall inner glue heat shrink tube 4 is wrapped with the secondary coil 2, and the outer double-wall inner glue heat shrink tube 4 is wrapped with the primary coil 3. The lead-out wire of the secondary coil 2 is led out from one end of the cylindrical magnetic core 1. In order to ensure safety and reliability, the lead-out wire secondary coil 2 and the lead-out wire welding area are wrapped with double-wall inner glue heat shrink tube 4, and the lead-out wire is also wrapped with double-wall inner glue heat shrink tube 4.

[0022] During the specific production, firstly, a double-wall inner rubber heat shrink tube 4 is put on the cylindrical magnetic core 1, and the double-wall inner rubber heat shrink tube 4 is put on the cylindrical magnetic core 1 and the heat shrink tube is blown tight, and the secondary coil 2 is wound on the outer layer of the double-wall inner rubber heat shrink tube 4, and the secondary coil 2 is wound with a number of turns using a straight-welded fully insulated wire FIW. Sufficient end space is left at both ends of the secondary coil 2 to ensure withstand voltage. When winding the secondary coil 2, it is necessary to ensure that the left and right end spaces are reserved to ensure the withstand voltage and creepage of the secondary coil 2.

[0023] Afterwards, a double-wall inner rubber heat shrink tube 4 is put on the wound secondary coil 2 and blown tight. After the secondary coil 2 is wound, a double-wall inner rubber heat shrink tube 4 is put on the outer layer, and then the primary coil 3 is wound, and the primary coil 3 is wound with enameled wire for the number of turns.

[0024] The lead-out wire of the secondary coil 2 is led out with an ultra-fine high-voltage wire 5. After the primary coil 3 is wound, the secondary high-end lead-out wire is led out with an ultra-fine high-voltage wire 5. A double-wall inner rubber heat shrink tube 4 is put on the place where the lead-out wire joint is welded. This step is to enhance the pressure resistance of the secondary high-end lead-out wire. After welding, the double-wall inner rubber heat shrink tube 4 is tightened at the welding place.

[0025] The utility model can adjust the power of the transformer or the transformation ratio of the transformer by adjusting the magnetic core of the transformer according to actual needs or by adjusting the number of primary and secondary turns. The transformer is easy to manufacture, has a simple structure and high withstand voltage, and is therefore suitable for various occasions.
