Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Please refer to Figures 1-5 , a magnetic ring adjustable video connecting line is shown, which is composed of a video transmission line 1, a magnetic ring 206 body assembly 2 and a connector 3.

[0031] The video transmission line 1 is used as the transmission carrier of the video signal, and the two ends are respectively provided with the connector 3, and the two connectors 3 are used for connecting with the computer host and the display screen, so that the transmission of the video signal between the computer host and the display screen is realized.

[0032] The magnetic ring assembly 2 comprises two upper and lower symmetrical upper shells 201, lower shells 202 and two magnet mounting shells 203. The upper shell 201 and the lower shell 202 are symmetrical structures, which form a cylindrical structure when combined, and are connected by hinge sheets. This connection allows the upper shell 201 and the lower shell 202 to rotate relative to each other like the pages of a book, facilitating the opening and closing of the magnetic ring 206 body assembly 2, and providing convenience for the installation, replacement and adjustment of the magnetic ring 206.

[0033] Two magnet mounting shells 203 are arranged on the upper shell 201 and the lower shell 202 respectively. Specifically, one of the magnet mounting shells 203 is fixed to the inner wall of the upper shell 201 by adhesive connection, and the other magnet mounting shell 203 is fixed to the inner wall of the lower shell 202 by adhesive connection. This fixing method ensures the stability of the magnet mounting shell 203 connection. Users can choose to install magnetic rings 206 in different magnet mounting slots 205 or replace magnetic rings 206 of different specifications according to actual electromagnetic interference conditions to achieve the best anti-interference effect.

[0034] The two ends of the magnet mounting shell 203 are provided with a plurality of spacing sheets 204, which play a role in separation and positioning. Adjacent two spacing sheets 204 form a magnet mounting slot 205, and one magnetic ring 206 is installed in each magnet mounting slot 205. The cross section of the magnetic ring 206 is in the shape of a "C", which allows the magnetic ring 206 to be easily installed in the magnet mounting slot 205, and the opening part of the "C" shape can accommodate the video transmission line 1 to pass through, ensuring that the magnetic ring 206 can play an anti-interference role on the video transmission line 1. The magnetic ring 206 is fixedly arranged in the magnet mounting slot 205 by adhesive, which ensures the stability of the position of the magnetic ring 206 in the magnet mounting slot 205 and prevents displacement due to the shaking of the connecting line.

[0035] In order to realize the close connection between the upper shell 201 and the lower shell 202, the upper shell 201 is provided with a locking sheet 207, which is in the shape of a sheet and has a buckle opening 208 at one end and is connected to the upper shell 201 at the other end. The lower shell 202 is provided with a boss 209, which is arranged at a position corresponding to the position of the buckle opening 208. When the magnetic ring 206 body assembly 2 needs to be closed, the upper shell 201 and the lower shell 202 are combined, and the buckle opening 208 is clamped on the boss 209. At this time, the buckle opening 208 and the boss 209 are clamped and connected, ensuring that the upper shell 201 and the lower shell 202 are tightly combined and preventing the magnetic ring 206 body assembly 2 from being accidentally opened. In order to ensure the stability and symmetry of the connection, the locking sheet 207 and the boss 209 are both provided with two, which are symmetrically arranged on the upper shell 201 and the lower shell 202.

[0036] In addition, the spacer 204 and the magnet mounting shell 203 are both made of rubber material and are integrally formed. The rubber material has good elasticity and buffering performance, and can absorb and disperse impact force when subjected to external impact, reducing the direct impact on the magnetic ring 206 and protecting the magnetic ring 206. At the same time, the integrally formed structure ensures the firmness and stability of the connection between the spacer 204 and the magnet mounting shell 203.

[0037] Working principle:

[0038] When the video signal is transmitted through the video transmission line 1, various electromagnetic interference sources existing in the external environment will generate alternating electromagnetic fields. At this time, the magnetic ring 206 wrapped around the video transmission line 1 plays a key role. Since the magnetic ring 206 has high magnetic permeability characteristics, according to the law of electromagnetic induction, the changing electromagnetic field will induce eddy currents in the magnetic ring 206.

[0039] These eddy currents in turn generate a secondary electromagnetic field opposite in direction to the external interference electromagnetic field. The arrangement of multiple magnetic rings 206 is equivalent to constructing a multi-layer reverse electromagnetic field barrier, which can more effectively counteract the interference of the external electromagnetic field on the video signal in the video transmission line 1 compared to the traditional single magnetic ring structure. Specifically, when the external electromagnetic interference is strong, by reasonably increasing the number of magnetic rings 206 in the multiple magnet mounting grooves 205 or selecting magnetic rings with higher magnetic permeability and stronger magnetism, the intensity of the secondary electromagnetic field generated is correspondingly enhanced to better resist interference; on the contrary, in the weak interference area, the configuration of magnetic rings 206 is appropriately reduced to avoid excessive shielding affecting the signal transmission efficiency.

[0040] In addition, the upper shell 201, the lower shell 202, and the spacer 204 and the magnet mounting shell 203 made of rubber material in the magnetic ring body assembly 2 not only provide physical protection for the magnetic ring 206, but also play an auxiliary role in electromagnetic shielding. On the one hand, they form a relatively closed space to constrain the secondary electromagnetic field generated by the magnetic ring 206 to concentrate as much as possible in the peripheral area of the video transmission line 1, enhancing the shielding effect; on the other hand, the elasticity of the rubber material can buffer the vibration when subjected to external impact, protecting the structural integrity of the magnetic ring 206 and ensuring its continuous and stable anti-interference function, thereby ensuring the stability and high-quality transmission of the video signal during transmission.

[0041] The details of the embodiments can be implemented, without departing from the spirit or essential characteristics thereof, in other specific forms. Thus, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

[0042] Furthermore, it should be understood that although the present specification describes particular embodiments, these are merely examples of the same, and that the specification is not limited to only the particular embodiments described. The specification is therefore to be considered in all respects as illustrative and not restrictive, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
