A connecting groove 5 is opened at the top end of the connecting post 4. A conductive post 6 is arranged at the bottom of the inner cavity of the connecting groove 5. By connecting to the conductive post 6 through an electric wire, it can be electrically connected to the matching circuit board 2 through the connecting post 4 and the connecting wire 3, so as to realize the function of supplying power to the central air conditioner. A limiting plate 7 is fixedly connected to the bottom of the connecting post 4, which can limit the movement of the connecting post 4;

[0028] A spring 8 is sleeved at the bottom end of the connecting post 4. A hexagonal nut 9 is sleeved in the middle of the connecting post 4. A connecting head 12 is sleeved at the top of the connecting post 4. A plurality of clamping strips 13 are fixedly connected to the top of the connecting head 12. A rotating ring 15 is sleeved in the middle of the clamping strip 13. Teeth 14 are arranged in the inner cavity of the clamping strip 13. By pulling the connecting post 4, the limiting plate 7 can be driven to squeeze the spring 8, and through the movement of the connecting wire 3, the buffering of the pulled electric wire can be realized, avoiding the loosening of the connecting head, improving the connection stability. And through the hexagonal nut 9, when the connecting head 12 is connected to the connecting post 4, the rotation and loosening of the connecting head 12 can be avoided, improving the thread connection strength between the connecting head 12 and the connecting post 4. And by rotating the rotating ring 15, while the rotating ring 15 rotates, it moves up and down, which can control the clamping strip 13 to squeeze the internal connecting wire 10, so as to facilitate the connection of the connecting wire 10 to the connecting head 12 and fix the connecting wire 10 in the middle of the connecting head 12;

[0029] A connecting wire 10 is connected to the middle of the clamping strip 13. Conductive cores 11 are arranged at both ends of the connecting wire 10. Mounting plates 16 are symmetrically and fixedly connected to both sides of the housing 1. By making the conductive core 11 fit with the conductive post 6, the connecting wire 10 can be electrically connected to the matching circuit board 2, which is convenient for connecting and supplying power to multiple central air conditioners. And through the mounting plates 16, it is convenient to fix the housing 1 on the central air conditioner for convenient installation and use.

[0030] As shown in the attachment Figure 1 The housing 1 is fixed on the top of the central air conditioner. The matching circuit board 2 is electrically connected to the circuit of the central air conditioner through the opening at the bottom of the housing 1. By fixing the housing 1 on the central air conditioner, it is convenient for wired control connection. By electrically connecting the matching circuit board 2 to the central air conditioner, it is convenient to use multiple central air conditioners in a connected manner.

[0031] As shown in the attachment Figures 1-3 The top end of the connecting wire 3 is connected to the bottom end of the connecting post 4. The connecting wire 3 is electrically connected to the conductive post 6 through the conductive wire in the middle of the connecting post 4. Through the connecting wire 3, it can be electrically connected to the conductive post 6, which is convenient for electrical connection with the connecting wire 10.

[0032] As shown in the attachmentFigures 1-5 As shown, a hexagonal nut 9 is arranged on the top of the housing 1.

By rotating the rotating ring 15 and squeezing the clamping strip 13, the gap between the plurality of clamping strips 13 can be reduced, causing the clamping strip 13 to deform, thereby squeezing the internal connecting wire 10, facilitating clamping and fixing.

[0035] As attached Figures 1-3 As shown, one end of the conductive core 11 extends into the inside of the connecting groove 5 and fits with the top wall of the conductive column 6. By electrically connecting the conductive core 11 to the conductive column 6, it is convenient to electrically connect the connecting wire 10 to the adapter circuit board 2, facilitating the online use of multiple central air conditioners and the power supply for the central air conditioners.

Then, one end of the connecting wire 10 is passed through the middle of the plurality of clamping strips 13 and extends into the inside of the connecting head 12, making the conductive core 11 located in the middle of the connecting head 12. Then, thread the connecting head 12 onto the top end of the connecting column 4 until the conductive core 11 is in close contact with the conductive column 6;

[0037] Then rotate the hexagonal nut 9 to make the hexagonal nut 9 fit with the connecting head 12, which can improve the threaded connection strength between the connecting head 12 and the connecting column 4 and avoid the rotation and loosening of the connecting head 12;

[0038] Then rotate the rotating ring 15 to squeeze the clamping strip 13, so that the clamping strip 13 clamps and fixes the connecting wire 10, and the conductive core 11 in the middle of the connecting wire 10 can be electrically connected to the conductive column 6;

[0039] Then electrically connect the other conductive core 11 at the end of the connecting wire 10 connected to another central air conditioner to the conductive core 11 at one end of a connecting wire 10 through a connector, and the on-line control can be completed for use;

[0040] When pulling the connecting wire 10, the connecting column 4 can be pulled through the clamping strip 13 and the connector 12, so that the limiting plate 7 pressurizes the spring 8, playing a buffering role.

[0041] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
