When the rear cover 13 is placed on the rear portion of the plug body 11 and a certain amount of pressure is applied, the first latches 134 elastically deform and snap into the first snapping positions 114, thereby achieving a secure engagement between the rear cover 13 and the plug body 11. The provision of the first snapping positions 114 and the first latches 134 simplifies the assembly process, allowing the user to complete the assembly of the plug 1 without the use of additional tools or fasteners.

[0062] See also Figure 7 、 Figure 8 In one embodiment, the rear portion of the socket body 21 is circumferentially provided with a plurality of second snap positions 214. These snap positions may be grooves, bayonets, or other positioning structures. The socket rear cover 23 is circumferentially provided with a plurality of second latches 234 that engage with the second snap positions 214. When the socket rear cover 23 is placed on the rear portion of the socket body 21 and a certain amount of pressure is applied, the second latches 234 elastically deform and snap into the second snap positions 214, thereby achieving a secure fastening between the socket rear cover 23 and the socket body 21. The provision of the second snap positions 214 and the second latches 234 simplifies the assembly process, allowing users to complete the assembly of the socket 2 without the use of additional tools or fasteners.

[0063] See also Figure 1 、 Figure 3 、 Figure 5 、 Figure 7In one embodiment, the socket body 21 is symmetrically provided with a plurality of guide posts 25. The protrusion height of the guide posts 25 relative to the socket body 21 is greater than the protrusion height of the socket power terminals 22 relative to the socket body 21. The plug body 11 is symmetrically provided with a plurality of guide holes 115 that mate with the guide posts 25. By adjusting the protrusion heights of the guide posts 25 and the socket power terminals 22 relative to the socket body 21 so that the protrusion height of the guide posts 25 is greater than the protrusion height of the socket body 21, the guide posts 25 automatically align before the power terminals are plugged into contact, ensuring proper connection between the power and signal terminals and preventing conductivity and signal transmission failures.

[0064] See also Figures 1 to 4 In one embodiment, the plug 1 further includes a front housing 15 and a waterproof ring 16. The front housing 15 snaps onto the head of the plug body 11. The front housing 15 and the outer wall of the plug body 11 form a waterproof ring mounting groove, into which the waterproof ring 16 is mounted. When the plug 1 is mated with the socket 2, the waterproof ring 16 is compressed and fills the small gap between the plug body 11 and the socket body 21, forming a tight waterproof barrier that effectively prevents external contaminants such as moisture and dust from entering the plug 1 and socket 2, protecting electrical components from damage.

[0065] See also Figure 3 、 Figure 4 In one embodiment, the head of the plug body 11 is circumferentially provided with a plurality of third snapping positions 116.

The provision of the third snapping positions 116 and the third snapping positions 151 simplifies the assembly process, allowing users to complete the assembly of the plug 1 without the use of additional tools or fasteners.

[0066] See also Figures 1 to 4In one embodiment, plug 1 further includes a plug washer 17 mounted on the mounting panel of plug body 11. First mounting nuts 117 are located at the four corners of the mounting panel of plug body 11. Screw holes 171 are provided at the four corners of plug washer 17 to engage with first mounting nuts 117. Screws can pass through plug washer 17 and connect with first mounting nuts 117 on the mounting panel, thereby mounting plug 1 on the charging pack. The primary function of plug washer 17 is to provide additional support and cushioning when plug 1 is mounted on a panel or other fixed surface, preventing damage to plug body 11 or the mounting panel caused by excessive pressure from tightening the screws.

[0067] See also Figure 5 、 Figure 7 In one embodiment, second mounting nuts 215 are provided at the four corners of the mounting panel of the socket body 21 , and the second mounting nuts 215 cooperate with screws to mount the socket 2 on the charging cabinet.
