[0019] ​To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] like Figure 1 and Figure 2 The diagram shows the existing technology of the V-groove ring of the conductive ring cooperating with a single brush, and the existing technology of the single brush holder cooperating with a single brush. These are existing technologies and will not be described in detail.

[0022] like Figures 3-6 As shown in the illustration, a conductive slip ring suitable for household appliances is provided in one embodiment of this utility model. It includes a rotor portion and a stator portion, and further includes: the rotor portion includes an insulator 3, on which a conductive ring 1 is fixed; one end of the insulator 3 is fixed with a multi-core cable 2, which is electrically connected to the conductive ring 1; the stator portion includes a cap 10, within which a housing 7 is fixed, and within the housing 7 is a PCB board 6; a brush 5 is fixed to the PCB board 6, and the brush 5 consists of multiple brush filaments arranged in a row, the brush 5 being connected to the conductive ring 1. The conductive ring 1 makes contact, ensuring that each bristle of the brush 5 is evenly in contact with the conductive ring 1, enabling the brush 5 to stably transmit large currents. The bundled brush 4 is fixed on the PCB board 6 and consists of multiple bristles. The conductive ring 1 has a conductive ring groove, and the bundled brush 4 is constrained within the conductive ring groove. This ensures that the conductive ring 1 makes multiple-point contact during operation, preventing the product from being subjected to pulling force impacts under multi-angle rotation, which could affect the transmission of product signals. During operation, the conductive ring groove prevents the bundled brush 4 from contacting the insulator 3, thus avoiding interference wear that could damage the slip ring. Both the bundled brush 4 and the brush 5 are connected to wires 9.

[0023] In this embodiment of the invention, the slip ring is installed at the rotation center of the device and mainly consists of two parts: a rotating part and a stationary part. The rotating part connects to the rotating structure of the device and rotates with it, and is called the "rotor". The stationary part connects to the fixed structure of the device and is called the "stator". By attaching the slip ring to the 360° rotating device, power and signals can be provided to the device through the stator-side wires and the rotor-side multi-core cables.

[0024] During operation, the stator of the terminal equipment fixes the cap 10 in place, and the multi-core cable 2 on the rotor side is connected to the moving parts at the front end of the terminal equipment, so that the rotor and stator parts move relative to each other. Utilizing the principle of elastic overlap, the conductive ring 1 of the rotor part and the brush bundle 4 and brush array 5 of the stator part form a stable and reliable rotating communication system.

[0025] As Figures 2-5 shown, as a preferred embodiment of the utility model, the conductive ring 1 is welded with the multi-core cable 2, and the conductive ring 1 is wrapped with the insulator 3 on the multi-core cable 2.

[0026] In the embodiment of the utility model, when using injection molding process, the multi-core cable 2 of the rotor part has strong pull resistance, high product precision, small coaxiality and small circle runout.

[0027] As Figures 2-5 shown, as a preferred embodiment of the utility model, the bundle brush 4 and the row brush 5 are made of noble metal alloy material.

[0028] In the embodiment of the utility model, the noble metal alloy material has good conductivity, elasticity, corrosion resistance and wear resistance.

[0029] As Figures 2-5 shown, as a preferred embodiment of the utility model, the PCB board 6 is welded with the capacitor 8, and the capacitor 8 includes a patch capacitor and a plug-in capacitor.

[0030] In the embodiment of the utility model, the capacitor plays the following main roles in the PCB board welding, voltage reduction: the capacitive reactance of the capacitor is used to reduce the voltage, filtering: the charge and discharge characteristics of the capacitor can be used to stabilize the current and reduce the voltage fluctuation. In the power supply circuit, the capacitor after the rectifier circuit can be used to filter out the unnecessary frequency components, ensure the normal operation of the equipment, signal coupling: the capacitor can couple and isolate the signal, improve the quality of signal transmission and anti-interference ability.

[0031] The above only is the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
