The connecting cable is provided between the fixing sheath 50 and the insulating sheath 70. Therefore, the connecting cable is separated from the refrigerant pipe 10 through the heat insulation sleeve 70, so that the connecting cable cannot be influenced by the refrigerant in the refrigerant pipe 10 when in use, and the use safety and the service life of the connecting cable are improved.

The utility model discloses still provide an air conditioner, this air conditioner includes connecting pipe subassembly 100, and the concrete structure of this connecting pipe subassembly 100 refers to above-mentioned embodiment, because this air conditioner has adopted the whole technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer given here. The indoor unit is provided with an indoor quick coupling 200 for connecting with the quick coupling 20 of the refrigerant pipe 10; and/or, the outdoor unit is provided with an outdoor quick coupling 300 for connecting with the quick coupling 20 of the refrigerant pipe 10. The indoor quick coupling 200 and the outdoor quick coupling 300 are used to be coupled with the quick coupling 20 of the joint pipe assembly 100, thereby achieving quick installation.

The both ends of connecting cable are the link, can set up to the same with the link of indoor set and with the specification of the grafting structure of the link of off-premises station, so can realize convenient operation connection. Especially in the european and american area, the manual installation costs are very expensive, and generally, the installation is personal, and manual connection can be facilitated by setting the specifications of both ends of the connection cable to be the same. Meanwhile, the joint structures at the two ends of the refrigerant pipe 10 (including the refrigerant liquid pipe 11 and the refrigerant gas pipe 13) may also be the same structure, so that the connection by the user is facilitated and the use is facilitated. When the fixing sleeve is installed, a wall penetrating hole needs to be formed in the wall, and a protective belt can be wound on the outer side of the fixing sleeve 15 and can be made of plastics or plastic materials. The protective tape may be the same length as the fixing cover 15, or may be only in a portion where the fixing cover 15 is in contact with the wall through hole. The fixing sleeve 15, the refrigerant pipe 10 and the connecting cable have a gap therebetween, and when the fixing sleeve 15 penetrates through the wall through hole, the fixing sleeve 15 is deformed to reduce the gap between the fixing sleeve and the refrigerant pipe 10 and the connecting cable, so that the diameter of the wall through hole is unnecessarily large, and the installation space is saved. Further, the deformation of the fixing sleeve 15 can be basically maintained through the protective belt, the fixing is convenient, for example, in the high altitude of a 19-storied building, the whole connecting pipe assembly which is preassembled is assembled, and the through-wall hole can be smoothly and conveniently passed through. Meanwhile, the protective belt is sleeved on the periphery of the fixed sleeve 15, so that the fixed sleeve 15 can be protected from being damaged by the wall through hole (the wall is generally of a reinforced concrete structure and the fixed sleeve 15 is easy to cut) when the protective belt passes through the wall through hole.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
