[0052] Example 1

[0053] like Figures 1 to 23 As shown, the present invention discloses a wire control box assembly, including a shell 1 and a rear cover 2, the shell 1 and the rear cover 2 are detachable to form an installation space for accommodating a circuit board 4, the circuit board 4 includes a circuit board body 401, a temperature sensing element 403 is arranged on the circuit board body 401, a separation notch 402 is arranged on the circuit board body 401, the temperature sensing element 403 is arranged on one side of the separation notch 402, and the temperature sensing element 403 is arranged close to the corner of the shell 1.

[0054] The wire control box assembly described in the present application performs temperature detection by arranging a temperature sensing element (for example, a temperature sensor, such as a thermistor or other sensor) on the circuit board 4. The temperature sensing element is separated from other circuits or lines by a separation notch 402 arranged on the circuit board 4, so as to reduce the influence of heat conduction from other components on the circuit board on the temperature sensing element, which helps to improve the accuracy of the temperature sensing element, thereby more accurately detecting the temperature without being disturbed by the heat generated inside the wire control box. At the same time, the circuit board 4 is arranged in the accommodation space between the detachably connected shell 1 and the rear cover 2, so as to improve the convenience of installation and maintenance of the circuit board 4 and the stability of the connection.

[0055] The wire control box assembly described in the present application improves the accuracy of temperature detection by improving the environment of the temperature sensing element, reducing the impact of heat conduction, and allowing users to control the air conditioner more reliably, thereby improving the user experience.

[0056] As a preferred example of the present application, the temperature sensing element 403 is arranged at a corner position on the circuit board body 401, and the separation notch 402 is arranged in a bent shape. This arrangement sets the temperature sensing element 403 at a corner position of the circuit board body 401. On the one hand, it can make it farther away from the heat-generating elements on the circuit board, which helps to reduce the possibility of heat conduction to the temperature sensing element. On the other hand, it is also convenient to design the separation notch 402 into an angle-changing or curved shape, which more effectively reduces heat conduction, improves the accuracy of the temperature sensing element, and reduces the distortion of temperature detection. As a preferred example of the present application, the length ratio of the connection part of the circuit board body 401 where the temperature sensing element 403 is located to the separation notch 402 is not greater than 0.3. The length of the connection part of the circuit board body 401 where the temperature sensing element 403 is located refers to the vertical distance between the rear end point of the separation notch 402 close to the connection part and the edge line of the circuit board body 401 close to the end point.

[0057] As a preferred example of the present application, a through temperature sensing hole 101 is provided on the side end plate 103 of the housing 1 at a position corresponding to the temperature sensing element 403. This arrangement allows the temperature sensing element 403 to be installed in the relatively closed installation space formed by the housing 1 and the rear cover plate 2, and by providing the temperature sensing hole 101 connected to the external space at a position close to the temperature sensing element 403 on the side end plate 103 of the housing 1, the external air can flow into the installation space through the temperature sensing hole 101 and be accurately detected by the temperature sensing element 403, further improving the accuracy of temperature detection by the temperature sensing element 403 inside the wire control box assembly.

[0058] As a preferred example of the present application, the temperature sensing hole 101 includes a first through hole 1011 and a second through hole 1012, and the first through hole 1011 and the second through hole 1012 are respectively arranged on two side plates of the side end plate 103 close to the temperature sensing element 403. As an example of the present application, the first through hole 1011 includes a plurality of temperature sensing through holes arranged in an intermittent manner, and the temperature sensing through holes include a plurality of temperature sensing through holes arranged in a continuous manner. This arrangement further improves the reliability of the external air entering the wire control box assembly and being accurately detected by the temperature sensing element 403, ensuring that the air conditioning system works more efficiently and provides a more comfortable environment.

[0060] This arrangement ensures the support and fixation of other electrical components such as the circuit board body 401 inside the shell 1 and the rear cover 2 by providing an intermediate pressure plate 3 with an avoidance notch 301. At the same time, the avoidance notch 301 ensures that it will not conflict with the temperature sensing element 403 on the circuit board 4, thereby achieving effective assembly and temperature monitoring of the equipment.

In this setting, the limit plate 601 can limit the screw gasket 604 of the wiring electrical connection to reduce the risk of improper wiring operation. At the same time, the limit plate 601 can separate adjacent wiring terminals 6, further avoiding short circuits caused by wiring contact between adjacent wiring terminals 6.

[0062] As a preferred example of the present application, a plug-in terminal 8 is provided on the circuit board body 401, and the plug-in terminal 8 is connected by a plug-in connection.

When the plug is closed, the USB connection hole is isolated to prevent dust, moisture or other external substances from entering the wire control box assembly, protecting the internal circuit from the external environment; when the plug is opened, the user can easily connect the USB device.
