Description

Technical Field

[0001] The utility model relates to the technical field of filter equipment, in particular to a novel filter inductance structure. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance and only hinders the change of current. If there is no current passing through the inductor, it will try to hinder the current from flowing through it when the circuit is connected. If there is current passing through the inductor, it will try to maintain the current unchanged when the circuit is disconnected. The inductor is also called a choke, a reactor, and a dynamic reactor. The motherboard inside the computer is mixed with various high-frequency circuits, digital circuits, and analog circuits. When they work, they will generate a large amount of high-frequency electromagnetic waves that interfere with each other. The filter has more than two inductance structures, each of which has an iron core and a coil group wound around the iron core. Moreover, the wire diameter and number of turns of the coil wound around the iron core will increase the volume of the inductor and make it heavier, making the filter occupy a large internal space and making the overall volume relatively larger.

[0003] An existing patent (publication number: CN 207690610 U) discloses an inductor structure of a filter, which has the characteristics of compact structure, small size, saving installation space, strong applicability, etc.

[0004] However, the above technical solution still has certain defects. First, when the coil of the device needs to be replaced after being damaged, usually the whole device is replaced. However, in some cases, only the coil is damaged and other components are in good condition. If the whole device is replaced, it will not only be cumbersome and time-consuming, but also increase the maintenance budget and the replacement cost will be high. Secondly, when the device is in use, a shielding cover is required to protect the internal equipment and shield external interference. Therefore, a relatively stable fixed structure is needed to prevent the shielding cover from falling off. For this reason, a new filter inductor structure is proposed. Utility Model Content
