The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0019] Example

[0020] See also Figure 1-2 , which is the first embodiment of the utility model, and this embodiment provides a square ultra-thin capacitive proximity sensor structure, including a sensor body 1, a fork-shaped detection surface 2 is arranged at the bottom of the sensor body 1, and a shielding cover 3 is pasted on the surface of one side of the sensor body 1, and the material of the shielding cover 3 is copper foil.

[0021] Specifically, mounting holes 4 are provided on both sides of the surface of the sensor body 1 , and a connecting line 5 is provided on one side of the sensor body 1 .

[0022] Furthermore, by opening mounting holes 4 on both sides, the sensor can be more firmly fixed on the device, thereby improving the stability of the sensor during use. The provision of the connecting wire 5 also ensures a firm connection between the sensor and the external device, avoiding loosening or disconnection during operation.

[0023] Specifically, grooves 6 are provided around the surface of the sensor body 1 , and there are two mounting holes 4 , each of which has a circular cross-sectional shape.

[0024] Furthermore, the groove 6 can be used to install additional accessories or provide more options for fixing. When integrated into different systems or applications, the groove 6 can be used as a slot for fluid sealant or for placing fixing elements, thereby making the installation more flexible.

[0025] Specifically, a circuit board is disposed inside the sensor body 1 and the circuit board includes a capacitive sensing element, a processing chip and an interface element.

[0026] Furthermore, by integrating capacitive sensing elements, processing chips and interface elements, its integrated design simplifies the product structure and improves the stability of the circuit and the efficiency of data processing.

[0027] Specifically, there are four grooves 6 , and the shielding cover 3 is coated with sealant around its periphery.

[0028] When in use, select the installation position of the sensor according to actual needs, ensure that the sensor detection surface can face the object to be detected, fix the sensor on the installation surface through the installation holes 4 on both sides of the sensor body 1, and use screws or other fixing elements. If the installation environment requires sealing, use the grooves 6 around the sensor body 1, add sealing rings or sealant during installation, and connect the sensor to the external device (controller or display) through the connecting line 5 on one side of the sensor body 1. After power-on, observe whether the sensor is working normally to ensure that the fork-shaped detection surface 2 can accurately detect approaching objects. According to actual use, adjust the sensitivity and detection distance of the sensor through external equipment, keep the shielding cover 3 clean, and prevent external pollutants from affecting the performance of the sensor.

[0029] In summary, by setting up the fork-shaped detection surface 2, it provides a larger detection area and a more dispersed sensing area, thereby improving the sensitivity and stability to approaching objects. The shielding cover 3 made of copper foil effectively isolates external interference signals, enhances the anti-interference ability of the sensor, and ensures the purity and accuracy of the signal. At the same time, the copper material has good conductivity to prevent interference from electromagnetic waves. A circuit board is provided inside the device, and capacitive sensing elements, processing chips and interface elements are integrated. The integrated design simplifies the product structure and improves the stability of the circuit and the efficiency of data processing.
