[0024] Reference Figure 1-Figure 5A split-type hanging air conditioner outdoor unit with a high-voltage connecting wire set with a waterproof plug. Conceptually, the main difference between high voltage and low voltage is the difference in use. High voltage is used as a power source, while low voltage is used for information transmission. The present application includes three conductive wires 1, conductive connectors 2 fixed at both ends of each conductive wire 1, and a waterproof plug 3. The waterproof plug 3 includes an elastic plug body 300, two rectangular or trapezoidal card plates 301 sequentially arranged on the top of the plug body 300, a card slot 302 formed between each card plate 301, at least two U-shaped grooves 303 sequentially arranged on the outer wall of the plug body 300, and a U-shaped protrusion 304 formed between each U-shaped groove 303. A waterproof board 305 is arranged at the rear end of the plug body 300, and the side wall of the waterproof board 305 extends out of the side wall of the plug body 300. The vertical height of the card plate 301 close to one end of the waterproof board 305 is greater than that of the card plate 301 away from the waterproof board 305. The vertical height of the card plate 301 at one end of the water plate 305 is arranged in an unequal height structure, which can prevent the liquid from flowing into the casing. A plurality of wire through holes 306 are provided on the plug body 300, and a plurality of conductive wires 1 pass through the plurality of wire through holes 306 accordingly. The wire through holes 306 are filled with insulating sealant 307 to tighten and seal the conductive wires 1 in the wire through holes 306. A protective tube 4 is sleeved on the periphery of at least one end of the plurality of conductive wires 1. The protective tube 4 can resist aging and wear and improve the protection performance. The insulating sealant 307 can be 8833 type instant glue, which is a glue that dries very quickly and can be quickly followed by glue, which is easy to use.

[0025] When in use, the waterproof plug 3 is installed on the casing hole of the air-conditioning outdoor unit, and two or more card plates 301 are correspondingly inserted into the slots at the casing hole. The card slots 302 between the card plates 301 cooperate with the convex ribs at the casing hole. The multiple U-shaped grooves 303 located on the outer wall of the plug body 300 cooperate with the convex ribs at the casing hole, and the waterproof plate 305 completely closes one end of the casing hole located in the air-conditioning outdoor unit. Because the waterproof plug 3 is provided with multiple card plates 301 and multiple U-shaped grooves 303, a multiple waterproof sealing structure is formed after cooperating with the casing hole to prevent liquid from flowing from outside the casing into the casing. The wire through hole 306 is filled with insulating sealant 307 to prevent liquid from flowing into the casing through the wire through hole 306. The conductive connectors 2 fixed at both ends of each conductive wire 1 can realize the quick electrical connection between the two ends of the connecting wire group and the two electrical appliances. The present application has a protective structure and a multiple waterproof structure, which can improve the anti-aging and wear performance and waterproof performance, and has a long service life and high safety.

[0026] In some embodiments, the conductive connector 2 is a U-shaped plug, and a U-shaped plug port 200 is provided at the first end of the U-shaped plug for quick connection with a screw column or a socket on an electrical appliance or circuit board. The second end of the U-shaped plug and the connecting part of the conductive wire 1 are sleeved with a heat shrink tube 5, which can improve the firmness of the connection, prevent loosening, and also play an insulating and protective role.

[0027] In some embodiments, the plug body 300 is an arc-shaped one-piece injection-molded silicone or rubber, and the protective tube 4 is a silicone tube or a rubber tube. Silicone or rubber has elasticity, good adhesion, sealing and related properties.

[0028] In some embodiments, protective tubes 4 are sleeved around both ends of the plurality of conductive wires 1 , so that both ends of the plurality of conductive wires 1 can be protected.

[0029] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although the embodiments of the utility model have been shown and described, ordinary technicians in this field can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and purpose of the utility model. The scope of the utility model is defined by the claims and their equivalents.
