Description

Technical Field

[0001] The utility model relates to the technical field of magnetic ring shells, in particular to a multi-spaced magnetic ring shell. Background Art

[0002] Magnetic rings are commonly used anti-interference components in electronic circuits. They have a good inhibitory effect on high-frequency noise. Under the action of the magnetic ring, normal useful signals can pass well, and high-frequency interference signals can be effectively suppressed. Moreover, the cost is low. Passing the entire bundle of cables through a ferrite magnetic ring constitutes a common-mode choke. In order to improve the protection of the magnetic ring, a magnetic ring shell will be installed on the surface of the magnetic ring.

[0003] The existing Chinese utility model patent with reference announcement number CN221927657U discloses a multi-spacing magnetic ring shell and a magnetic ring assembly. The shell comprises an outer cover shell, which is formed by splicing a first shell and a second shell. The first shell and the second shell are each provided with a placement slot for storing the magnetic ring body. The surfaces of the first shell and the second shell are both movably connected with a spacing adjustment component for adjusting the winding spacing. The spacing adjustment component is provided with a starting component inside to assist in the adjustment. The utility model adjusts the winding angle of the cable by providing a spacing adjustment component on the surface of the outer cover shell and connecting a starting component to its end, thereby improving the winding efficiency of the magnetic ring body. By utilizing an auxiliary slot provided at the bottom of the placement slot, the magnetic ring body connected to the auxiliary mounting plate is more easily and stably installed inside the outer cover shell.

[0004] Existing magnetic ring shells generally limit the position of the coil by opening holes on the inside and outside. This method requires passing the wire through the openings when threading, which is very inconvenient. In addition, this method requires re-piercing the copper wire when adjusting the coil spacing, which is also very inconvenient. Utility Model Content
