Further, since one end of the wire harness 220 is connected to the first connecting part 210 and the other end is connected to the second connecting part, at this time the first connecting part 210 and the second connecting part can play a protective effect on both ends of the wire harness 220, so that the plug assembly 200 can avoid damage to both ends of the wire harness 220 during transportation, it should be noted that in the prior art, during transportation, the other end of the wire harness 220 is not connected to the second connecting part, that is to say, one end of the wire harness 220 is connected to the first connecting part 210 and the other end is not connected to the rubber shell, at this time the end not connected to the rubber shell is easy to be damaged during transportation, thereby affecting the use of the wire harness 220.
[0035] The fixing assembly 300 comprises a positioning portion 310, a limiting portion 320 and a guide portion 330. The guide portion 330 is arranged in the mounting hole 110. The positioning portion 310 is arranged in the first connecting portion 210. The limiting portion 320 is arranged in the mounting plate 100. The positioning portion 310 can pass through the mounting hole 110 along the guide portion 330 to the other side of the mounting plate 100. It should be noted that, in use, the second connecting portion in the plug assembly 200 first passes through the mounting hole 110, then the wire harness 220 passes through the mounting hole 110, and finally part of the structure of the first connecting portion 210 passes through the mounting hole 110. When the first connecting portion 210 passes through the mounting hole 110, the positioning portion 310 arranged on the first connecting portion 210 can pass through the mounting hole 110 along the guide hole and to the other side of the mounting plate 100. At this time, the positioning portion 310 and the first protrusion 230 are located on the two sides of the mounting plate 100, respectively. The first connecting portion 210 is rotated to make the positioning portion 310 cooperate with the limiting portion 320. The limiting portion 320 can limit the positioning portion 310 on the other side of the mounting plate 100. The positioning portion 310 and the first protrusion 230 can clamp the mounting plate 100 to fix the first connecting portion 210 on the mounting plate 100, thereby fixing the plug assembly 200 on the mounting plate 100. By adopting the second connecting portion that can pass through the mounting hole 110, the guide portion 330 is arranged in the mounting hole 110, the positioning portion 310 is arranged in the first connecting portion 210, and the limiting portion 320 is arranged in the mounting plate 100, so that the plug assembly 200 is more convenient to assemble with the mounting plate 100, which is much more convenient than the existing technology in which the rubber shell cannot pass through the nut, thereby solving the technical problems in the existing technology. Further, in order to improve the clamping force between the positioning portion 310 and the first protrusion, a gasket can be arranged between the first protrusion and the mounting plate 100 at this time. By increasing the gasket, the spacing between the first protrusion and the positioning portion 310 is reduced, thereby increasing the clamping force of the first protrusion and the positioning portion 310 on the mounting plate 100, so that the connection between the first connecting portion 210 and the mounting plate 100 is more stable.
[0036] In an embodiment, referring to Figure 1 , Figure 4 The first protrusion 230 is configured in a ring structure. Further, when the first protrusion 230 is arranged in a ring structure, the contact area between the first protrusion 230 and the mounting plate 100 is increased. By increasing the contact area between the first protrusion 230 and the mounting plate 100, the acting force between the first protrusion 230 and the mounting plate 100 is increased, thereby stably limiting the first connecting portion 210 on the mounting plate 100. In some embodiments, the first protrusion 230 can adopt a block structure. At this time, the number of the first protrusions 230 is multiple. The multiple first protrusions 230 are arranged on the outer side of the first connecting portion 210.
