[0015] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] In the present application, a plug hole is provided on the vertical side of one end of the terminal 6, and the coil connection spring 7 is inserted on the terminal 6 to realize the connection.

[0017] See Figure 1 , Figure 2 and Figure 3 What is shown is an optimized connection structure between a high-voltage conductor and a side-mounted coil, comprising an insulating tube 1, the lower end of which is connected to a polytetrafluoroethylene tube 2, a pressing plate 3 is arranged on the upper part of the insulating tube 1, and a cylinder head sheath 4 is arranged on the lower part of the pressing plate 3; a high-voltage conductor 5 is passed through the insulating tube 1, one end of the high-voltage conductor 5 vertically passes through the rear end of the insulating tube 1 to connect to a terminal 6, and a coil connection spring 7 is vertically inserted into the end of the terminal 6; the terminal 6 and the coil connection spring 7 are both covered with an elastic sheath 8 on the outside.

[0018] The coil connection spring 7 is a columnar structure in the middle and a conical structure at both ends. One end of the coil connection spring 7 passes through the elastic sheath 8 and is exposed. The elastic sheath 8 is an L-shaped structure, and an anti-collision protrusion 9 is arranged at the corner of the outer wall of the elastic sheath 8. The anti-collision protrusion 9 and the elastic sheath 8 are an integral structure.

[0019] The working principle of the optimized connection structure between the high-voltage conductor and the side coil is as follows:

[0020] Firstly, the operator only needs to hold the elastic sheath 8 and press it directly into the coil to achieve a fixed connection. The elastic sheath 8 wrapped on the outside can hold the coil tightly against the end of the coil connecting spring 7 to achieve an effective connection and improve the connection strength. The side-mounted structure design is achieved through the L-shaped elastic sheath 8, which can overcome the installation defects brought about by the traditional top-mounted structure.

[0021] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
