Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to a protection structure for an inductor. Background Technique

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. Its structure is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only impedes the change of current. If the inductor is in a state without current passing through, when the circuit is switched on, it will try to impede the current from flowing through it; if the inductor is in a state with current passing through, when the circuit is switched off, it will try to maintain the current unchanged. Therefore, an inductor is also called a choke device, that is, a device that prevents the change of current.

[0003] During the use of an inductor, heat will be generated. The existing inductor is provided with a protective shell on the outside, but the heat accumulates inside the protective shell and cannot be effectively dissipated. Long-term high-temperature operation may accelerate the aging process of the inductor and shorten its service life. Therefore, it is necessary to provide a protective shell that can avoid the inability to dissipate heat to improve the service life of the inductor. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a protection structure for an inductor to solve the problem proposed in the above background technique that during the use of an inductor, heat will be generated.

[0019] Second, based on the first beneficial effect, through the provided fixing hole, side connecting plate, first connecting plate, second connecting plate, through hole, clamping column, and spring, when the top plate is installed on the bottom plate, the staff presses the top plate downward.

[0040] The function of the protective shell 21 may be to protect the internal core components and prevent the magnetic core 121 and the coil 13 from being physically damaged. The annular groove 22 is located in the middle of the protective shell 21, and the heat dissipation groove 23 can use the external air flow to take away the heat generated during the operation of the inductor;

[0043] Working principle:

[0044] When the inductor is in use;

[0047] The mechanism of controlling the opening of the heat sink 23 by rotating the block 25 provides a simple, direct and effective method for the user to adjust the heat dissipation performance of the inductor;

[0048] This step ensures stable operation and long-term reliability of the equipment and helps to increase the service life of the inductor.

The spring 36 makes the clamping column 35 have a certain elasticity.

[0054] Working principle:

[0055] When the top plate 12 is mounted on the bottom plate 11;

[0056] First, the staff presses the top plate 12 downward, and when the lower surface of the protective shell 21 contacts the clamping column 35 and continues to press downward, the clamping column 35 moves outward to compress the spring 36;

[0057] Then, when one end of the clamping column 35 is positively aligned with the fixing hole 31, the spring 36 quickly recovers its deformation;

[0058] One end of the clamping post 35 is clamped into the fixing hole 31 to fix the protective shell 21;
