Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic compatibility, in particular to an overvoltage protection type magnetic bead. Background Art

[0002] Overvoltage protection ferrite beads are passive electronic components used to suppress high-frequency noise. They combine the basic functions of a ferrite bead with overvoltage protection. Primarily made of ferrite material, they possess high resistivity and high magnetic permeability. They effectively convert interfering signals into heat at high frequencies, thereby addressing radiation and interference issues. Overvoltage protection ferrite beads operate based on their high-frequency filtering properties. They are equivalent to a resistor and inductor in series, but both resistance and inductance vary with frequency. At high frequencies, the ferrite bead presents high impedance, effectively filtering out noise while minimizing the impact on low-frequency and DC signals.

[0003] In the existing technology, overvoltage protection magnetic beads usually have wires wrapped inside. These magnetic beads are easily affected by pressure deviation when installed on the equipment through a clamp. Since the drive of the clamp often relies on devices such as cylinders and motors, the applied pressure may be uneven or excessive. Once a large force is applied, the wires inside the magnetic beads will bend, especially magnetic beads with bare wires or thin metal inside are more susceptible to being affected. This physical stress will significantly reduce the product yield, affecting production efficiency and product quality. At the same time, the clamp end is often sharp and can easily scratch the surface of the magnetic beads, resulting in a reduction in their service life. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an overvoltage protection type magnetic bead.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an overvoltage protection type magnetic bead, comprising a magnetic bead body, both ends of the magnetic bead body are fixed with power connection ends, a square groove is provided on the side of the power connection end, an end insulating insert is fixed on the inner wall of the square groove, an installation ladder groove is provided on one side of the end insulating insert, an entry piece is slidably connected to the inner wall of the installation ladder groove, a reinforcing end transverse rib is fixed on one side of the entry piece, and a side reinforcing rib is fixed on the side of the reinforcing end transverse rib.

[0006] Preferably, an inner wall of the end insulating block is provided with an inner arc groove, and a spring arc piece is fixed to one side of the ladder entry member, and the surface of the spring arc piece is nested with the inner wall of the inner arc groove of the block. In the prior art, the end insulating block and the ladder entry member are often installed by gluing. Although this method can better maintain its fixing effect, there are some difficult to solve problems in actual operation. Due to the medium effect of glue between the components, it is difficult for workers to accurately judge whether the end insulating block and the ladder entry member are installed in place. This uncertainty increases the difficulty of operation and easily leads to excessive pressure between the components, ultimately causing damage to the components and reducing the yield rate. In addition, the gluing connection method also makes disassembly difficult. Once maintenance or replacement of parts is required, additional workload and time cost are increased. To address such problems, the present invention adopts a method of installing a spring arc piece. When the worker installs the insulating block and the ladder entry member, friction is generated between the spring arc piece and the installation ladder groove, causing the assembly to slow down. At the same time, when the spring arc piece reaches the inner arc groove of the block, the spring arc piece pops out to stop and fix the assembly, while providing feedback to the worker, thereby achieving the effect of improving the yield rate.

[0007] Preferably, a circumferential groove is provided on the top of the side reinforcement rib, a clamping lift is fixed to the inner wall of the circumferential groove, and double-ended indicator lights are fixed on both sides of the circumferential groove. In the prior art, when the staff needs to remove the magnetic beads, due to the lack of force points, the tools are likely to cause damage to the magnetic beads or scratch the surface, etc., resulting in damage to the components. This situation not only affects the normal use of the product, but also greatly increases the maintenance cost. To solve this problem, the utility model adopts the method of installing a clamping lift to solve it, which makes it convenient for the staff to use tools to pick up the clamping lift, thereby facilitating the removal of the magnetic beads, thereby improving user experience and reducing maintenance costs.

[0008] Preferably, a folded edge block is fixed on the side of the reinforcing end transverse rib, so that the folded edge block protects the edge of the magnetic bead main body that is easily worn, thereby achieving the effect of increasing the service life of the equipment.

[0009] Preferably, a cross pad is fixed on the top of the connection and fixation point between the side surface of the reinforcing end transverse rib and one end of the side peripheral reinforcing rib, so that the contact point with the circuit board is buffered by the cross pad, thereby achieving the effect of increasing the service life of the equipment.

[0010] Preferably, a triangular fixing piece is fixed to the side surface of the electrical connection end, and one side of the triangular fixing piece is fixed to the side surface of the reinforcing end transverse rib, thereby improving the fixing effect and achieving the effect of improving product stability.

[0011] Preferably, a rubber curved pad is fixed on the top of the curved edge of the folded edge, thereby improving the protection effect, reducing friction, and achieving the effect of increasing the service life of the equipment.

[0012] Beneficial effects:

[0013] 1. In the prior art, overvoltage protection magnetic beads usually have wires wound inside. These magnetic beads are easily affected by pressure deviation when they are installed on the equipment through a clamp. Since the drive of the clamp often relies on devices such as cylinders and motors, the applied pressure may be uneven or excessive. Once a large force is applied, the wires inside the magnetic beads will bend. In particular, magnetic beads with bare wires or thin metal sheets inside are more susceptible to this. This physical stress will significantly reduce the product yield, affecting production efficiency and product quality. At the same time, the clamp end is often sharp and can easily scratch the surface of the magnetic beads, resulting in a reduction in their service life. To address such problems, this utility model The new method solves the problem by installing reinforcing end transverse ribs. When the magnetic beads are produced, the staff slides the ladder into the end insulating block, and then fixes the side reinforcing ribs to the side of the reinforcing end transverse ribs, so that multiple reinforcing ribs are arranged on the side of the magnetic bead body. When the installation equipment clamps the magnetic beads, due to the presence of the reinforcing ribs, the clamp will not directly contact the body of the magnetic bead body, preventing the wires inside the magnetic bead from bending, and at the same time preventing the clamp end from scratching the surface of the magnetic bead body, and making the magnetic bead body have a certain impact and pressure resistance, so that the magnetic beads can maintain their integrity to the greatest extent during the production, transportation and installation process, thereby achieving the effect of improving the yield rate.

[0014] 2. In the prior art, the installation of the end insulating insert and the ladder entry piece is often connected by gluing. Although this method can better maintain its fixing effect, there are some difficult-to-solve problems in actual operation. Due to the medium effect of glue between the components, it is difficult for the staff to accurately judge whether the end insulating insert and the ladder entry piece are installed in place. This uncertainty increases the difficulty of operation and easily leads to excessive pressure between the components, which eventually causes damage to the components and reduces the yield rate. In addition, the gluing connection method also makes disassembly difficult. Once maintenance or replacement of parts is required, additional workload and time cost will be added. To solve such problems, the utility model adopts the method of installing spring arc pieces to achieve a solution. When the staff installs the insulating insert and the ladder entry piece, friction is generated between the spring arc piece and the installation ladder groove, which slows down the component. At the same time, when the spring arc piece reaches the arc groove in the block, the spring arc piece pops out to stop and fix the component, and at the same time gives feedback to the staff, so as to achieve the effect of improving the yield rate.

[0015] 3. In the prior art, when workers need to remove magnetic beads, due to the lack of force points, tools can easily damage the beads or scratch the surface, resulting in damage to the components. This situation not only affects the normal use of the product, but also greatly increases maintenance costs. To address this problem, the present invention solves it by installing a clamping and lifting piece, making it easier for workers to use tools to lift the clamping and lifting piece, thereby facilitating the removal of the magnetic beads, thereby improving user experience and reducing maintenance costs.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive.

[0024] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

[0026] Reference Figures 1-5A magnetic bead with overvoltage protection comprises a magnetic bead body 1, both ends of which are fixed with power connection ends 101, a square groove is provided on the side of the power connection end 101, an end insulating insert 2 is fixed on the inner wall of the square groove, a mounting ladder groove 201 is provided on one side of the end insulating insert 2, a ladder entry piece 202 is slidably connected to the inner wall of the mounting ladder groove 201, a reinforcing end transverse rib 203 is fixed on one side of the ladder entry piece 202, and a side reinforcing rib 204 is fixed on the side of the reinforcing end transverse rib 203. An inner arc groove 3 is provided on the inner wall of the end insulating block 2, and a spring arc piece 301 is fixed on one side of the ladder piece 202. The surface of the spring arc piece 301 is nested with the inner wall of the inner arc groove 3. The installation of the end insulating block 2 and the ladder piece 202 is often connected by gluing. Although this method can better maintain its fixing effect, there are some difficult problems in actual operation. Due to the medium effect of glue between the components, it is difficult for the staff to accurately judge whether the installation of the end insulating block 2 and the ladder piece 202 is in place. This uncertainty increases the difficulty of operation and easily leads to excessive pressure between the components. Insufficient, eventually leading to damage to the component, reducing the yield rate. In addition, the adhesive connection method also makes disassembly difficult. Once maintenance or replacement of parts is required, it will increase additional workload and time cost. The solution is to install a spring arc piece 301. When the staff installs the end insulating insert 2 and the ladder piece 202, friction is generated between the spring arc piece 301 and the installation ladder groove 201, which slows down the component. At the same time, when the spring arc piece 301 reaches the arc groove 3 in the block, the spring arc piece 301 pops out to stop and fix the component, and at the same time gives feedback to the staff, so as to achieve the effect of improving the yield rate.

[0027] A circumferential groove 4 is provided on the top of the side reinforcement rib 204, and a clamping and lifting piece 401 is fixed on the inner wall of the circumferential groove 4. Double-ended indicator lights 402 are fixed on both sides of the circumferential groove 4. When the staff needs to remove the magnetic beads, due to the lack of a force point, the tool is likely to damage the magnetic beads or scratch the surface, etc., resulting in damage to the components. This situation not only affects the normal use of the product, but also greatly increases the maintenance cost. The problem is solved by installing a clamping and lifting piece 401, which makes it easy for the staff to use tools to pick up the clamping and lifting piece 401, thereby facilitating the removal of the magnetic beads, thereby improving user experience and reducing maintenance costs. A folded edge block 6 is fixed on the side of the reinforcing end transverse rib 203, which protects the edge of the magnetic bead body 1 that is easily worn by the folded edge block 6, thereby improving the service life of the equipment. A cross pad 403 is fixed on the top of the connection and fixing point between the side of the reinforcing end transverse rib 203 and one end of the side reinforcement rib 204, which buffers the contact point with the circuit board by the cross pad 403, thereby improving the service life of the equipment. A triangular fixing member 5 is fixed to the side of the power supply terminal 101. One side of the triangular fixing member 5 is fixed to the side of the reinforcing end transverse rib 203, improving the fixing effect and enhancing the product stability. A rubber pad 601 is fixed to the top of the curved edge of the folded edge guard 6 to improve the protection effect, reduce friction, and increase the service life of the equipment.

[0028] The working principle of the present invention is as follows: when the magnetic beads are produced, the staff slides the ladder piece 202 into the end insulating insert 2, and then fixes the side peripheral reinforcing ribs 204 to the side of the reinforcing end transverse ribs 203, so that multiple reinforcing ribs are arranged on the side of the magnetic bead body 1. When the installation equipment clamps the magnetic beads, due to the presence of the reinforcing ribs, the clamp will not directly contact the body of the magnetic bead body 1, preventing the wires inside the magnetic beads from bending, and at the same time preventing the clamp end from scratching the surface of the magnetic bead body 1, and making the magnetic bead body 1 have a certain impact and pressure resistance, so that the magnetic beads can maintain their integrity to the greatest extent during production, transportation and installation. When the staff installs the end insulating insert 2 and the ladder piece 202, friction is generated between the spring arc piece 301 and the installation ladder groove 201, causing the assembly to slow down. At the same time, when the spring arc piece 301 reaches the arc groove 3 in the block, the spring arc piece 301 pops out to stop and fix the assembly, and gives feedback to the staff at the same time.
