Description

Technical Field

[0001] The utility model relates to the technical field of inductor coils, in particular to an inductor coil with a protective shell. Background Art

[0002] An inductor is a device that works on the principle of electromagnetic induction. When current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire of this electromagnetic field will induce the wires within the range of this electromagnetic field. The effect on the wire that generates the electromagnetic field is called "self-inductance", that is, the changing current generated by the wire itself generates a changing magnetic field, and this magnetic field further affects the current in the wire; the effect on other wires within the range of this electromagnetic field is called "mutual inductance".

When the shell needs to be removed, it is inconvenient to disassemble the shell. Therefore, the utility model provides an inductor coil with a protective shell. Utility Model Content
