Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to a fastening and clamping magnetic ring structure. Background Art

[0002] Magnetic rings are commonly used anti-interference components in electronic circuits. They have a good inhibitory effect on high-frequency noise and are generally made of ferrite materials. Magnetic rings have different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies. When the signal frequency increases, the impedance of the magnetic ring increases sharply. Some semi-cylindrical magnetic rings are assembled using special mounting sleeves when used, so that two semi-cylindrical magnetic rings can form a complete cylindrical magnetic ring.

[0003] Among them, the snap-on magnetic ring fixing device for PCB installation disclosed in application number CN202221417176.3 is also an increasingly mature technology. A snap-on magnetic ring fixing device for PCB installation can firmly and reliably connect the magnetic core to the PCB board, is easy to assemble, and can protect the magnetic core and coil. This device is more suitable for the situation where the PCB board is installed horizontally. The base is set horizontally and can better support the metal shielding cover. This device can also be used when the PCB board is in a vertical state.

[0004] Based on this, I agree with the advantages of the above products, but there are still the following defects:

[0005] The magnetic ring fixing device lacks a fastening structure when fastened, which causes the magnetic ring to become loose easily, thus affecting the use effect. Utility Model Content

[0006] The utility model aims to provide a fastening and snap-fitting magnetic ring structure to solve the problem in the background art that the magnetic ring is prone to loosening due to the lack of a fastening structure.

[0007] The utility model provides a fastening snap-fit ​​magnetic ring structure, comprising a left magnetic ring sleeve, a right magnetic ring sleeve and a snap-fit ​​assembly, wherein the left magnetic ring sleeve and the right magnetic ring sleeve are movably connected through the snap-fit ​​assembly, the left magnetic ring sleeve and the right magnetic ring sleeve are respectively installed with a left magnetic ring and a right magnetic ring inside, and the left magnetic ring sleeve and the right magnetic ring sleeve are movably connected outside through the snap-fit ​​assembly;

[0008] Among them, the locking assembly includes a right magnetic ring sleeve with a through groove at one end extending to the outside, an arc rod is installed at one end inside the through groove, the surfaces of the two arc rods are sleeved with a return spring, one end of the return spring is located outside the arc rod and a locking rod is rotatably installed, the middle parts of the two locking rods are connected with a connecting plate and a pushing rod is installed on the outside, the outside of the right magnetic ring sleeve is located on one side of the pushing rod and a movable groove for moving the pushing rod is opened, one end of the left magnetic ring sleeve is provided with a circular groove larger than the diameter of the locking rod, a locking groove is opened between the two circular grooves, protrusions are installed on the upper and lower sides of the inside of the locking groove and a pressing block is connected on one side, a pressing spring is installed between the protrusions, the locking groove and the pressing block both extend to the outside of the left magnetic ring sleeve, and the top and bottom between the two locking rods are provided with a fixing groove for locking the protrusion.

[0009] In this embodiment, the left magnetic ring sleeve and the right magnetic ring sleeve are doubly connected by means of a locking assembly and a snap assembly to prevent the left magnetic ring sleeve and the right magnetic ring sleeve from falling off. The locking rod of the right magnetic ring sleeve is pushed into the circular groove of the left magnetic ring sleeve by the elasticity of the reset spring. When the locking rod enters the circular groove, the fixed groove of the locking rod will lock with the protrusion, thereby closing the right magnetic ring sleeve and the left magnetic ring sleeve.

[0010] In one embodiment of the utility model, the buckle assembly includes a pushing block connected to the outside of the right magnetic ring sleeve, and the outside of the left magnetic ring sleeve is installed with a mounting plate. A fixing plate is connected between the mounting plates through a circular shaft. The outside of the fixing plate is fixedly connected to one side of the middle part of the press buckle, and the surface of the circular shaft is provided with a torsion spring.

[0011] In this solution, the push block is moved toward one side of the push buckle, thereby causing one side of the push buckle to tilt up.

[0012] In an implementation manner of the utility model, the pushing block and the pressing buckle are both fixedly connected with buckle blocks at their ends close to each other.

[0013] In this solution, the push block and the pressing buckle are buckled by the buckle block, so that the buckle block connection is tight and stable.

[0014] In one embodiment of the utility model, the left magnetic ring sleeve and the right magnetic ring sleeve are provided with an installation groove on the outside of one end away from the buckle assembly, the left magnetic ring sleeve is located inside the installation groove and a sleeve is installed inside the installation groove, and the right magnetic ring sleeve is located inside the installation groove and a rotating shaft is installed, and the rotating shaft is located inside the sleeve.

[0015] In this solution, force and torque can be transmitted through the cooperation between the rotating shaft and the sleeve. When the left magnetic ring sleeve and the right magnetic ring sleeve need to rotate or transmit power, the rotating shaft can be used as a connection point to enable the two magnetic ring sleeves to rotate relative to each other or transmit force.

[0016] In an implementation manner of the utility model, insulating pads are sleeved between the left magnetic ring, the right magnetic ring, and the left magnetic ring sleeve and the right magnetic ring sleeve.

[0017] In this solution, the current conduction or magnetic field interference between the isolated magnetic ring sleeve and the magnetic ring is reduced by the insulating pad, thereby improving the safety and stability of the system.

[0018] In an implementation manner of the utility model, the left magnetic ring sleeve, the right magnetic ring sleeve, the insulating pad, the left magnetic ring and the right magnetic ring are all arranged in a hemispherical shape.

[0019] In this solution, the hemispherical setting makes the contact area relatively large, the force can be evenly dispersed, the local stress concentration is reduced, and the stability and reliability of the connection are improved.
