Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4In this embodiment of the present invention, a wiring structure for an air conditioner control device includes a control panel body 1 consisting of a controller housing 101, a wiring port 102, and a tightening hole 103. The wiring port 102 is located at the bottom of the rear shell of the controller housing 101, and the tightening hole 103 is located at the rear end of the rear shell of the wiring port 102. The tightening hole 103 and the wiring port 102 are interconnected and vertically distributed. A rectangular mounting groove 104 is provided on the inner side of the wiring port 102. A wiring assembly 2 is installed on the wiring port 102 through the rectangular mounting groove 104. The wiring assembly 2 is used to realize the electrical connection and fixing operation between the cable end and the control panel body 1.

[0031] Wiring assembly 2 includes a clamping unit and a bending reinforcement unit;

[0032] The end of the clamping unit cable is electrically connected and fixed to the main body 1 of the control panel;

[0033] The bending reinforcement unit is used to further improve the connection force between the cable end and the control panel body 1;

[0034] The clamping unit includes a 7-shaped back plate 201, an L-shaped fixing plate 202, a notch 203, a rectangular clamping frame 204, and fastening screws 207;

[0035] The L-shaped fixing plate 202 is fixed to one end of the top horizontal part of the 7-shaped back plate 201. The notch slot 203 is symmetrically opened on both sides of the L-shaped fixing plate 202. The rectangular pressing frame 204 is sleeved on the outside of the L-shaped fixing plate 202 through the notch slot 203.

[0036] The 7-shaped backplate 201, L-shaped fixing plate 202, and notch groove 203 are installed as a whole on the inside of the wiring port 102 and the rectangular mounting groove 104. The vertical part of the 7-shaped backplate 201 is attached to the inner wall end face of the wiring port 102. The top horizontal part of the 7-shaped backplate 201 is attached to the top of the inner wall of the rectangular mounting groove 104. The bottom end of the vertical part of the 7-shaped backplate 201 is attached to the bottom of the inner wall of the rectangular mounting groove 104. The end of the L-shaped fixing plate 202 away from the 7-shaped backplate 201 is snapped into the top inner side of the rectangular mounting groove 104. The bottom horizontal part of the rectangular clamping frame 204 extends to the bottom of the inner wall of the rectangular mounting groove 104.

[0037] Fastening screws 207 are distributed inside tightening holes 103 and pass through the top horizontal part of rectangular clamping frame 204 from top to bottom and are attached to the upper surface of the horizontal part of L-shaped fixing plate 202. Fastening screws 207 are threadedly connected to rectangular clamping frame 204.

[0038] After the cable end is inserted into the wiring port 102, it is located between the lower surface of the horizontal part of the L-shaped fixing plate 202 and the upper surface of the bottom horizontal part of the rectangular clamping frame 204. The clamping operation of the cable end is achieved by tightening the fastening screw 207 to move the rectangular clamping frame 204 upward.

[0039] The bending reinforcement unit includes an L-shaped bending block 205 and an arc-shaped pressure plate 206;

[0040] The L-shaped bending block 205 is fixed to one end of the horizontal part of the bottom of the rectangular pressing frame 204, and the vertical part of the L-shaped bending block 205 is attached to the vertical part of the 7-shaped back plate 201.

[0041] The arc-shaped pressure plate 206 is fixed to the top of the vertical part of the L-shaped bending block 205 and tilted downwards;

[0042] When the rectangular clamping frame 204 moves upward, the "L"-shaped structure composed of the L-shaped bending block 205 and the arc-shaped pressure plate 206 realizes the bending and clamping operation of the cable end;

[0043] The width of the 7-shaped back panel 201 and the rectangular clamping frame 204 matches the inner wall width of the rectangular mounting groove 104.

[0044] In this embodiment, it should be noted that the main body 1 of the control panel is a common model of central air conditioning control panel on the market. The back of the vertical part of the 7-shaped back panel 201 is connected to the controller wire inside the controller housing 101. The 7-shaped back panel 201, the L-shaped fixing plate 202, the rectangular pressing frame 204, the L-shaped pressing block 205, and the arc-shaped pressing plate 206 are all made of metal.

[0045] The operating principle is as follows when connecting the air conditioner's control cable to the main body 1 of the control panel:

[0046] Insert the front end of the control cable into the wiring port 102 (it should be noted that at this time, the fastening screw 207 is loosened, and the bottom horizontal part of the rectangular clamping frame 204 is far away from the horizontal part of the L-shaped fixing plate). When the front end of the control cable contacts the vertical part of the 7-shaped back plate 201 (i.e., the control cable cannot be inserted further), tighten the fastening screw 207 with a tool. Since the fastening screw 207 is threadedly connected to the rectangular clamping frame 204, and the bottom end of the fastening screw 207 is in contact with the L-shaped fixing plate 202, when the fastening screw 207 is tightened, it can drive the rectangular clamping frame 204 to move upward. The upward movement of the bottom horizontal part of the rectangular clamping frame 204 can press the front end of the control cable against the lower surface of the horizontal part of the 7-shaped back plate 201.

[0047] At the same time, the rectangular clamping frame 204 simultaneously drives the L-shaped bending block 205 and the arc-shaped pressure plate 206 to move upward. The arc-shaped pressure plate 206 contacts the foremost part of the control cable and squeezes it, causing the foremost part of the control cable to bend and get stuck in the area between the vertical part of the L-shaped fixing plate 202 and the vertical part of the 7-shaped back plate 201. The foremost part of the control cable is in an "L" shape. At the same time, the arc-shaped pressure plate 206 presses the bent part, which further improves the connection between the control cable and the control panel body 1 and effectively prevents the control cable from becoming loose and falling off.

[0048] Please refer to this carefully. Figures 2-4 The horizontal part of the L-shaped fixing plate 202 protrudes into the wiring port 102, and the part of the L-shaped fixing plate 202 near the port of the wiring port 102 has an arc-shaped structure.

[0049] The horizontal length of the top and bottom of the arc-shaped pressure plate 206 is less than the length of the horizontal part of the 7-shaped back plate 201.

[0050] In this embodiment: the arc structure of the L-shaped fixing plate can provide guidance for the insertion of the end of the control cable. Similarly, the arc-shaped pressure plate 206 also provides guidance for the contact between the end of the control cable and the vertical part of the 7-shaped back plate 201.

[0051] Furthermore, the arc-shaped structure of the arc-shaped pressure plate 206 makes the bending of the control cable end smoother, and while bending the control cable end, it can also form a pressing operation at the bending point.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
