[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4As shown, this utility model provides a technical solution: an ignition coil power plug structure, including a docking assembly 1, which consists of a power plug 101, a power pin 102, a positioning post 103, and an ignition trigger module 104. The power pin 102 is fixedly connected to the bottom front of the power plug 101, and the positioning post 103 is fixedly connected to the center of the front of the power plug 101. One end of the positioning post 103 is engaged with the ignition trigger module 104. An installation assembly 2 consists of a mounting plate 201, a spring 202, a retaining ball 203, mounting bolts 204, and a protective cover, all of which are engaged with the two ends of the back of the power plug 101. The mounting plate 201 has a circular slot on its side, and a spring 202 is fixedly connected to the inner wall of the slot. A retaining ball 203 is fixedly connected to one end of the spring 202. A threaded groove is formed on the back of the mounting plate 201, and a mounting bolt 204 is threadedly connected to the inner wall of the groove. A protective cover 205 is fixedly connected to one end of the mounting plate 201. The mounting plate 201 is configured with a power plug 101, a power pin 102, a positioning post 103, and an ignition trigger module 104. A step is designed on the power pin 102, and the power pin 102 is injection molded onto the power plug 101. The power plug 101 has a positioning post 103. The positioning post 103 is designed with a step, and the positioning post 103 and the three power pins 102 on the power plug 101 form a triangle. This ensures that the ignition trigger module 104 is fixed in the X, Y, and Z directions relative to the power plug 101 after it is assembled onto the power plug 101. This prevents the power pins 102 from tilting or having too small a gap with the power plug 101 after the module is assembled onto the power plug 101. Through the design of the power plug 101, mounting plate 201, spring 202, retaining ball 203, mounting bolt 204, and protective cover 205, the operator can rotate the mounting plate 201 during use. The mounting bolt 204 on 01 is used to disconnect the protective cover 205 from the power plug 101, allowing maintenance operations to be performed inside the device. After maintenance, the mounting plate 201 on the protective cover 205 is inserted into the slot on the power plug 101. The retaining ball 203 on the mounting plate 201 will be springed into the circular slot corresponding to the retaining ball 203 in the slot by the spring 202, allowing the power plug 101 to be pre-installed with the protective cover 205. Then, the mounting bolt 204 is screwed into the corresponding threaded grooves on the mounting plate 201 and the power plug 101. This setup facilitates maintenance operations inside the device for the staff.

[0022] The inner wall of the spring 202 is provided with a telescopic rod 3. One end of the telescopic rod 3 is fixedly connected to the center of the back of the ball 203. Through the arrangement of the spring 202, the telescopic rod 3 and the ball 203, the telescopic rod 3 can prevent irreversible deformation when the spring 202 is deformed during use.

[0023] A connecting groove is provided on the back edge of the power plug 101. The inner wall of the connecting groove is threaded to one end of the mounting bolt 204. With the power plug 101 and the mounting bolt 204, when in use, one end of the mounting bolt 204 will be screwed into the connecting groove on the power plug 101.

[0024] The ignition trigger module 104 has a trigger groove on its front edge. The inner wall of the trigger groove is engaged with one end of the power pin 102. With the ignition trigger module 104 and the power pin 102, the power pin 102 will be inserted into the trigger groove on the ignition trigger module 104 during use.

[0025] The ignition trigger module 104 has a positioning groove at the center of its front side. The inner wall of the positioning groove is engaged with the outer surface of the positioning post 103. Through the setting of the ignition trigger module 104 and the positioning post 103, the positioning post 103 will connect with the positioning groove on the ignition trigger module 104 during use, thereby positioning and connecting the power plug 101 and the ignition trigger module 104.

[0026] A fixing groove is provided at one end of the inner wall of the mounting plate 201. The inner wall of the fixing groove is fixedly connected to one end of the telescopic rod 3. With the mounting plate 201 and the telescopic rod 3, one end of the telescopic rod 3 is fixed in the fixing groove on the inner wall of the mounting plate 201 during use.

[0027] In this invention, the working steps of the device are as follows:

[0028] First step: Design a step on the power pin 102, and injection mold the power pin 102 onto the power plug 101. A positioning post 103 is designed on the power plug 101, and a step is designed on the positioning post 103. The positioning post 103 and the three power pins 102 on the power plug 101 form a triangle, so that after the ignition trigger module 104 is assembled onto the power plug 101, the assembly position in the X, Y, and Z directions relative to the power plug 101 is fixed, preventing the power pins 102 on the power plug 101 from tilting or having too small a gap with the power plug 101 after the module is assembled onto the power plug 101.

[0029] The second step: The operator can rotate the mounting bolt 204 on the mounting plate 201 to disconnect the protective cover 205 from the power plug 101, and perform maintenance operations inside the device. After maintenance, the mounting plate 201 on the protective cover 205 is inserted into the slot on the power plug 101. The retaining ball 203 on the mounting plate 201 will be pushed into the circular slot corresponding to the retaining ball 203 by the spring 202, so that the power plug 101 and the protective cover 205 are pre-installed. Then the mounting bolt 204 is screwed into the corresponding threaded grooves on the mounting plate 201 and the power plug 101.
