Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of common mode inductance, specifically relates to a common mode inductance with quick -mounting structure. BACKGROUND

[0002] Common mode inductance is a coil with opposite winding directions and the same number of turns symmetrically wound on a closed magnetic loop. It is mainly used to suppress common mode interference signals, which are interference signals present on both signal lines in a circuit. By filtering out common mode electromagnetic interference on the signal line, common mode inductance can protect the circuit from external electromagnetic interference, while preventing the circuit itself from emitting electromagnetic interference, ensuring the normal operation of other electronic devices in the same electromagnetic environment.

[0003] The working principle of common mode inductance is based on electromagnetic induction and the interaction of magnetic fields. When common mode interference signals enter the circuit, they will generate an induced electromotive force on the common mode inductance, thus forming a reverse current. This reverse current cancels out the common mode interference signals, achieving the effect of suppressing interference. In addition, common mode inductance can also be designed to convert common mode signals to differential mode signals, thereby improving signal quality and reliability. During production and assembly, the upper cover and bottom cover of the common mode inductance are precisely assembled and assembled by using a flexible metal plate as a connecting medium. However, this assembly method requires the use of specific installation tools or fixtures to assist in the operation, which undoubtedly increases the complexity of assembly, thereby reducing the overall installation efficiency of the common mode inductance. At the same time, this method also affects the possibility of quick disassembly, making the operation more tedious when the common mode inductance needs to be quickly replaced or maintained, thereby reducing work efficiency.
