Description

Technical Field

[0001] The utility model relates to the technical field of ferrite magnetic rings, in particular to a split ferrite magnetic ring. Background Art

[0002] Ferrite core is a high-frequency magnetic material, mainly made of ferrite material. Ferrite core is an electronic component commonly used in inductors, transformers, and filter circuits. It realizes the transmission and conversion of circuit signals by forming a magnetic field inside it. Ferrite core is widely used in electronic components, mainly because it can effectively integrate many advantages such as electromagnetic interaction, stable magnetic permeability, low loss and high controllability. The main function of ferrite core is to serve as a magnetic component in electronic devices for managing and regulating current. It easily generates magnetic flux by winding the coil around the core, offsetting the impact of current on passive components, thereby making the whole more stable.

[0003] Since a coil needs to be wound around the outside of the magnetic core, it is more troublesome to wind the coil on the existing integrated ferrite magnetic core. Therefore, a split ferrite magnetic core has emerged. However, the connection of the split ferrite magnetic core is not well protected and fixed. The connection part is easy to loosen during use, affecting the stability of the split ferrite magnetic core. Utility Model Content

[0004] The main purpose of the present invention is to provide a split ferrite magnetic ring, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A split ferrite magnetic ring includes a first ferrite magnetic ring and a second ferrite magnetic ring. A magnetic core device is commonly installed in the middle of one corresponding end of the first ferrite magnetic ring and the second ferrite magnetic ring. A connecting device is commonly installed in the front and rear of one corresponding end of the first ferrite magnetic ring and the second ferrite magnetic ring.

[0007] Preferably, the connecting device includes a connecting post and a connecting sleeve. The connecting post has a screw hole at the front end, a protective shell is mounted on the outer surface of the connecting post, and a mounting screw is mounted on the front end of the connecting sleeve. The connecting post is fixedly mounted on the right end of the first ferrite ring, and the connecting post and the first ferrite ring are integrally formed. The connecting sleeve is fixedly mounted on the left end of the second ferrite ring, and the connecting sleeve and the second ferrite ring are integrally formed. The clamping blocks at both ends of the cylindrical core are aligned with the clamping slots on the first and second ferrite rings, and the clamping blocks are then inserted into the clamping slots, thereby clamping the cylindrical core between the first and second ferrite rings. At this time, the connecting post is also properly inserted into the connecting sleeve. The mounting screw is then screwed into the screw hole to secure the connecting post within the connecting sleeve. Not only is the ferrite ring installed, but the protective shell is also provided on the outer surface of the connecting post, further protecting the connection of the split ferrite ring.

[0008] Preferably, the magnetic core device comprises a cylindrical magnetic core having winding grooves engraved on its outer surface. Clamps are mounted on both the left and right ends of the cylindrical magnetic core, and the cylindrical magnetic core is clamped between the first and second ferrite rings via the clamps. The winding grooves in the cylindrical magnetic core facilitate close winding of the coil around the cylindrical magnetic core.

[0009] Preferably, a slot is provided in the middle of one corresponding end of the No. 1 ferrite magnetic ring and the No. 2 ferrite magnetic ring.

[0010] Preferably, the positions of the connecting post and the connecting sleeve correspond to each other on the left and right, and the positions of the mounting screw, the mounting hole and the screw hole correspond to each other on the front and back.

[0011] Preferably, the card slot and the card block are positioned correspondingly on the left and right, and both the card slot and the card block are rectangular in shape.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The connecting post on the connecting device is designed as an integrated whole with the No. 1 ferrite magnetic ring, and the connecting sleeve is designed as an integrated whole with the No. 2 ferrite magnetic ring. When the No. 1 ferrite magnetic ring and the No. 2 ferrite magnetic ring need to be connected, first align the blocks at both ends of the cylindrical core on the core device with the slots on the No. 1 ferrite magnetic ring and the No. 2 ferrite magnetic ring, and then insert the blocks into the slots, so that the cylindrical core is also clamped between the No. 1 ferrite magnetic ring and the No. 2 ferrite magnetic ring. At this time, the connecting post will also be inserted into the connecting sleeve, and then the mounting screw is screwed into the screw hole to fix the connecting post in the connecting sleeve. Not only the installation of the ferrite magnetic ring is completed, but also a protective shell is provided on the outer surface of the connecting post, which further protects the connection of the split ferrite magnetic ring and improves the stability of the split ferrite magnetic ring after installation.

[0014] 2. The winding grooves on the cylindrical core make it easier for the coil to be tightly wound around the cylindrical core. BRIEF DESCRIPTION OF THE DRAWINGS
