[0001] The utility model relates to the technical field of inductance coils, and specifically relates to a protection device for inductance coils. Background Technique

[0002] An inductance coil is an electronic component based on the principle of electromagnetic induction. It generates a magnetic field around a wire through the flow of current. This magnetic field not only affects other surrounding wires but also the wire itself that generates it. After a large number of searches, the publication number is CN219553384U, which discloses a protection device for inductance coils. This protection device for inductance coils improves the installation efficiency and enhances the practicability.

[0003] However, although the above-mentioned protection device for inductance coils is well-designed, the metal parts included in the positioning structure may generate electromagnetic interference during the operation of the inductance coil in actual use, affecting the normal working performance of the coil. At the same time, when the device is impacted or pulled, the structural stability of the positioning mechanism is poor, and thus it is prone to breakage, and it will cause physical pressure on the inductance coil, resulting in a change in the winding pitch of the coil. At this time, the change in the winding pitch may lead to uneven magnetic field distribution, affecting the electromagnetic characteristics of the inductance coil, and further may affect the working effect of the electronic device. For this reason, a protection device for inductance coils is proposed to solve the above problems. Content of the Utility Model
