[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 it only hinders the change of current.

[0003] In existing inductor designs, there is often a lack of effective protection measures for the inductor body, which makes the inductor susceptible to external electromagnetic interference, thereby affecting its performance. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that there is a lack of effective protection measures for the inductor body in the prior art, which makes the inductor easily affected by external electromagnetic interference, thereby affecting its performance, and proposes an anti-interference structure for the inductor.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An anti-interference structure for an inductor includes an inductor body and further includes:

[0007] A protective shell, wherein a receiving gap for placing the inductor body is formed in the protective shell;

[0008] Wherein, a protective cover for sealing the protective shell is provided on the upper side of the protective shell, and the protective shell and the protective cover are both made of metal aluminum to protect the inductor body, and a set of connecting components is provided between the protective shell and the protective cover, and the connecting components are used to quickly fix the protective cover on the protective shell;

[0009] and an extrusion assembly used in conjunction with the connection assembly, the extrusion assembly being used to quickly release the connection between the protective housing and the protective cover;

[0010] A feeding assembly is arranged in the protective shell and is used to feed the inductor body out of the protective shell.

[0011] In a possible design, two matching blocks are fixed to the top end of the protective shell, and two matching grooves are provided at the bottom end of the protective cover, and the two matching grooves are matched with the two matching blocks respectively.

[0012] In a possible design, the connecting assembly includes a first groove opened in the protective cover, two snap-in blocks slide in the first groove, snap-in grooves are opened in the two matching blocks, the two snap-in blocks are snap-in with the two snap-in grooves respectively, and a snap-in spring is fixed between the two snap-in blocks.

[0013] In a possible design, the extrusion assembly includes a second groove opened in the protective cover, a pressing plate slides in the second groove, two extrusion plates are fixed to the bottom end of the pressing plate, and extrusion grooves are opened in the two clamping blocks. The two extrusion plates move downward and penetrate into the two extrusion grooves respectively, and the two extrusion plates are respectively in extrusion contact with the inclined surfaces of the two extrusion grooves.

[0014] In a possible design, a return spring is fixed to the bottom end of the pressing plate, the bottom end of the return spring is fixed in the second groove, and the cross-section of the pressing plate is convex.

[0015] In one possible design, the feeding assembly includes a third groove opened in the protective shell, a slide plate slides in the third groove, a lifting block is fixed to the top of the slide plate, the lifting block moves upward and penetrates into the protective shell, a lifting spring is fixed at the bottom end of the slide plate, and the lifting spring is fixed in the third groove.

The two clamping blocks are respectively clamped into the two clamping grooves to achieve a fixed connection between the position of the protective shell and the protective cover. When it needs to be removed, only the pressing plate needs to be pressed, and the pressing plate drives the two extrusion plates to move downward. The two extrusion plates squeeze the inclined surfaces of the two extrusion grooves respectively, and the two clamping blocks are squeezed to move in a direction close to each other, so that the two clamping blocks leave the clamping groove and return to the first groove. After the protective cover is removed, the sliding plate and the lifting block are pushed upward by the elasticity of the lifting spring, and the lifting block sends the inductor body out.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1

[0027] Reference Figure 1-Figure 3 , an anti-interference structure for an inductor, which is used in the field of inductor technology, includes an inductor body 3, and a protective shell 1 for protecting the inductor body 3. An accommodation gap is designed inside the protective shell 1 for accurately placing the inductor body 3. In order to protect the inductor from external electromagnetic interference, the protective shell 1 and the protective cover 2 are both made of metal aluminum, which has good conductivity and shielding effect.

[0028] On the top of the protective shell 1, we fixedly installed two matching blocks 5, which match with the two matching slots 4 at the bottom of the protective cover 2. When the protective cover 2 is covered on the protective shell 1, the matching blocks 5 and the matching slots 4 are tightly combined to provide a closed protective environment for the inductor.

[0029] The design of the connection assembly enables the protective cover 2 to be quickly and firmly fixed on the protective housing 1. Specifically, a first groove 8 is provided in the protective cover 2, and two clamping blocks 7 are slidably installed therein. The two clamping blocks 7 match the clamping grooves 6 in the matching blocks 5 on the protective housing 1. When the protective cover 2 is covered on the protective housing 1, the clamping blocks 7 will automatically snap into the clamping grooves 6 under the action of the clamping springs 10, thereby achieving a fixed connection between the two.

[0030] In order to facilitate the removal of the protective cover 2, we also designed an extrusion assembly. The assembly includes a second groove 11 opened in the protective cover 2, and a pressing plate 12 slidably installed therein. Two extrusion plates 13 are fixed to the bottom end of the pressing plate 12, and the two extrusion plates 13 match the extrusion groove 9 in the clamping block 7. When the protective cover 2 needs to be removed, just press the pressing plate 12 downward, and the extrusion plate 13 will contact the inclined surface of the extrusion groove 9 and generate an extrusion force, so that the clamping block 7 pops out of the clamping groove 6, thereby realizing the rapid removal of the protective cover 2; the reset spring 14 will keep the pressing plate 12 in place.

[0031] Example 2

[0032] refer to Figure 1-Figure 3 , improved on the basis of Example 1: we also designed a feeding assembly, which includes a third groove 15 opened in the protective shell 1, a slide plate 16 sliding in the third groove 15, a lifting block 18 fixed to the top of the slide plate 16, the lifting block 18 moves upward and penetrates into the protective shell 1, a lifting spring 17 is fixed to the bottom end of the slide plate 16, the lifting spring 17 is fixed in the third groove 15, and is used to send the inductor body 3 out of the protective shell 1, after the protective cover 2 is removed, the slide plate 16 and the lifting block 18 are pushed upward by the elasticity of the lifting spring 17, and the lifting block 18 sends the inductor body 3 out.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
