Description

Technical Field

[0001] This utility model relates to the field of electrical connection wire assembly technology, and in particular to a split wall-mounted air conditioner air guide strip control wire assembly. Background Technology

[0002] An air conditioner air deflector is an accessory installed on the indoor unit of a split-type wall-mounted air conditioner, typically consisting of a metal bracket and a guide cloth. Its main function is to regulate the direction of airflow from the air conditioner, preventing cold or hot air from blowing directly onto people, thus protecting users from discomfort or health effects. For example, in summer, it prevents discomfort caused by direct cold air; in winter, it guides warm air to better cover the indoor space. The control wiring harness is used to control the operation of the air conditioner air deflector.

[0003] The utility model patent with authorization announcement number CN223109352U discloses a low-voltage wire for a USB female plug on a split inverter air conditioner main control board. It includes multiple conductive wires, with a USB female plug and a connector plug installed at both ends of the wire assembly. The USB female plug includes a hollow shell with openings at both ends, a terminal fixing plate installed inside the hollow shell, and multiple conductive terminals installed side-by-side on the terminal fixing plate. A slot is formed between the terminal fixing plate and the inner wall of the hollow shell. The connector plug includes an insulating shell with openings at both ends and a hollow interior, an elastic plate integrally formed on the top of the insulating shell, and multiple plug sleeves installed side-by-side inside the insulating shell. This design ensures that the conductive wire plug is securely fastened to the electrical socket, preventing it from easily coming loose, and that the connection between the conductive wire and the plug is stable.

[0004] The air guide vane control signal is a low-voltage, weak electrical signal, easily affected by electromagnetic interference from high-voltage equipment such as the motor and compressor inside the air conditioner, or by electromagnetic noise in the external environment. Furthermore, the core wires of the air guide vane control wiring harness are easily scratched by sheet metal parts when connected to the motor. While the aforementioned utility model solves the problem of unstable connection between the conductive wire and the plug, it still has shortcomings in terms of electromagnetic interference resistance, ensuring stable signal transmission, and scratch resistance. Utility Model Content

[0005] In order to overcome at least one of the technical problems existing in the prior art, this utility model provides a split wall-mounted air conditioner air guide strip control wire assembly, which has better anti-electromagnetic interference performance, more stable signal transmission, and stronger scratch resistance.

[0006] A split wall-mounted air conditioner air guide strip control wiring assembly includes six wires, each with an insulation layer and a shielding layer to prevent electromagnetic interference. The two ends of each wire extend from the ends of the shielding layer. Two wires form a first wire group, and the other four form a second wire group. Each end of the first and second wire groups is connected to a terminal plug. The input ends of the first and second wire groups can be connected to the air conditioner's main control board socket via the terminal plugs, and the output ends of the first and second wire groups can be connected to a stepper motor via the terminal plugs. A heat-shrink tubing is tightly secured between one end of the shielding layer and the terminal plugs at the output ends of the first and second wire groups to prevent the wires from being scratched. Heat-shrink tubing is also tightly secured at both ends of the shielding layer to prevent the wires from loosening or rotating.

[0007] In some embodiments, the shielding layer is aluminum foil Mylar tape or tin-plated copper braided mesh.

[0008] In some embodiments, the heat shrink tubing is a polyolefin heat shrink tubing or a perfluoroethylene propylene heat shrink tubing, which is tightened by heating with a hot air gun.

[0009] In some embodiments, the six wires are colored brown, yellow, red, blue, green, and black for easy identification; the first wire group includes two wires colored brown and yellow, and the second wire group includes four wires colored red, blue, green, and black.

[0020] Reference Figure 1 A split wall-mounted air conditioner air guide strip control wiring assembly includes six wires 1, each wire 1 having an insulating layer around its perimeter. The six wires 1 are also surrounded by a hollow, tubular shielding layer 2 to prevent electromagnetic interference. The two ends of the six wires 1 extend from the two ends of the shielding layer 2. Two of the six wires 1 form a first wire group 3, and the other four form a second wire group 4. Each end of the first wire group 3 and the second wire group 4 is connected to a terminal plug 5 for conducting electrical signals. The input ends of the first wire group 3 and the second wire group 4 can be connected to the air conditioner main control board socket via the terminal plug 5, and the output ends of the first wire group 3 and the second wire group 4 can be connected to a stepper motor via the terminal plug 5. A heat shrink tubing 6 is tightly secured between one end of the shielding layer 2 and the terminal plug 5 located at the output ends of the first wire group 3 and the second wire group 4 to prevent the wires 1 from being scratched. Heat shrink tubing 6 is also tightly secured at both ends of the shielding layer 2 to prevent the wires 1 from loosening or rotating.

[0021] The six wires 1 of this application are secured into a control wire group by the shielding layer 2, which prevents the six wires 1 from being scattered. The shielding layer 2 can also reflect and absorb external electromagnetic waves, especially for the control signal of the air guide strip with a long transmission distance, which can reduce the action delay or false triggering caused by low frequency and high frequency interference. It can also bind the electromagnetic field generated when the control line is working inside the shielding layer, so as to avoid interfering with other sensitive components inside the air conditioner. The heat shrink tubing 6 can fix the wires 1 to both ends of the shielding layer 2, preventing the wires 1 from loosening and rotating. The heat shrink tubing 6 can also prevent the output end of the control wire group from being scratched by sheet metal parts when wiring to the stepper motor, which can extend the service life.

[0022] In some embodiments, the shielding layer 2 is aluminum foil Mylar tape or tin-plated copper wire braided mesh; aluminum foil Mylar tape includes aluminum foil and PET film, which is lightweight and low cost; tin-plated copper wire braided mesh is flexible, oxidation resistant and long-lasting.

[0023] In some embodiments, the heat shrink tubing 6 is a polyolefin heat shrink tubing or a perfluoroethylene propylene heat shrink tubing, which is tightened after being heated with a hot air gun; the polyolefin heat shrink tubing has a low shrinkage temperature, can be quickly operated with a hot air gun, is not easy to burn the wires, is insulating and environmentally friendly, and can be customized in colors such as red, yellow, and blue, which facilitates circuit identification and management; the perfluoroethylene propylene heat shrink tubing has good temperature resistance and is resistant to acids, alkalis and organic solvents.

[0024] In some embodiments, the six wires 1 are colored brown, yellow, red, blue, green and black for easy identification; the first wire group 3 includes two wires 1 in brown and yellow, and the second wire group 4 includes four wires 1 in red, blue, green and black for easy line identification and management.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been 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 embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
