Description

A copper contact with an anti-arc structure Technical Field

[0001] This utility model relates to the field of copper contact technology, and in particular to a copper contact with an anti-arc structure. Background Technology

[0002] Existing copper contacts often generate electric arcs when disconnected from the power supply. This arcing is primarily caused by the high voltage difference resulting from the instantaneous flow of current when the contact is broken, which ionizes the air and forms an arc. The high temperature and intense current of the arc generate significant heat on the copper contact surface, easily causing corrosion, burning, or oxidation, affecting the contact's conductivity and lifespan. However, current copper contacts lack an arc-proof structure, making it impossible to effectively suppress arcing. With repeated arcing, the copper contact surface gradually becomes damaged, forming carbon deposits or melting marks. This not only increases the equipment failure rate but may also lead to more serious electrical faults and even fire hazards. Over long-term use, the contact performance of the copper contacts deteriorates, and the contact resistance when current flows increases, further affecting the stability and safety of the equipment. Therefore, a copper contact with an arc-proof structure is needed to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies. When copper contacts are disconnected from the power supply during use, they often generate an electric arc. This arc is primarily caused by the high voltage difference resulting from the instantaneous flow of current when the contacts are disconnected, which ionizes the gas in the air, thus forming an arc. The high temperature and intense current of the arc generate significant heat on the surface of the copper contacts, easily causing corrosion, burning, or oxidation, affecting the conductivity and lifespan of the contacts. However, current copper contacts do not have an anti-arc structure, making it impossible to effectively suppress the generation of arcs. With repeated arcing, the surface of the copper contacts gradually becomes damaged, forming carbon deposits or melting marks. This not only increases the failure rate of the equipment but may also lead to more serious electrical faults and even fire hazards. With long-term use, the contact performance of the copper contacts deteriorates, and the contact resistance when current passes through increases, further affecting the stability and safety of the equipment. This invention provides a copper contact with an anti-arc structure.

[0009] In a preferred embodiment, the top of the support plate is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer surface of the slider.

A spring is provided on the outer surface of the second telescopic rod. One end of the spring is fixedly connected to the top of the base, and the other end of the spring is fixedly connected to one side of the support plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention uses a permanent magnet ring to apply an external magnetic field to change the path of the electric arc, causing the arc to deflect and making it easier to disperse and extinguish.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] As shown in Figures 1-4, this utility model provides a technical solution: a copper contact with an anti-arc structure, including a base 1, a housing 2 fixedly connected to the top of the base 1, multiple support rods 3 fixedly connected to the top of the base 1, a permanent magnet ring 4 fixedly connected between the top ends of the multiple support rods 3, a spiral heat sink 5 fixedly connected to the outer surface of the permanent magnet ring 4, a spiral wire 6 spirally wound around the outer surface of the permanent magnet ring 4, one end of the spiral wire 6 electrically connected to an output wire 7, and the other end of the spiral wire 6 electrically connected to a receiving wire 8. The top of the base 1 is fixedly connected to... A plurality of first telescopic rods 16 are connected, and a support plate 10 is fixedly connected to one end of the plurality of first telescopic rods 16. A copper contact block 11 is fixedly installed on the top of the support plate 10. A connecting block 12 is electrically connected to one side of the copper contact block 11. A slider 13 is electrically connected to one side of the connecting block 12. A support block 14 is electrically connected to one side of the slider 13. A flexible wire 9 is electrically connected to one side of the support block 14. One end of the flexible wire 9 is electrically connected to one end of the receiving wire 8. A sliding hole 15 is opened on the top of the support plate 10. The inner wall of the sliding hole 15 is slidably connected to the outer surface of the slider 13.

[0022] Through the above embodiments, after the copper contact 11 is separated from the power supply, the generated electric arc will run along the copper contact 11, connecting block 12, slider 13, soft wire 9, receiving wire 8 and surrounding wire 6. The permanent magnet ring 4 is set into a circle and a spiral heat sink 5 is set on the permanent magnet ring 4, which helps to distribute the magnetic field evenly around. Through the action of the magnetic field, the permanent magnet ring 4 can generate Lorentz force on the electric arc, deflect the trajectory of the electric arc, and reduce the duration of the electric arc between the contact point or the conductive path. At the same time, the spiral heat sink 5 is designed on the surface of the permanent magnet ring 4 to ensure that the electric arc can quickly contact the cooling surface for heat exchange when it occurs.

[0023] By applying an external magnetic field through the permanent magnet ring 4, the path of the electric arc is changed, causing the path of the electric arc to deflect, making the electric arc easier to disperse and extinguish. At the same time, the electric arc can be guided to the heat absorption area of ​​the spiral heat sink 5 to absorb the heat generated by the electric arc, thereby reducing the temperature of the electric arc and reducing the damage of the electric arc to the surrounding conductor 6, thus achieving the effect of preventing electric arc.

[0024] A second telescopic rod 17 is fixedly connected to the top of the base 1. One end of the second telescopic rod 17 is fixedly connected to one side of the support plate 10. A spring 18 is provided on the outer surface of the second telescopic rod 17. One end of the spring 18 is fixedly connected to the top of the base 1, and the other end of the spring 18 is fixedly connected to one side of the support plate 10.

[0025] In the above embodiments, after the copper contact 11 contacts the power source, it further pushes the base 1, causing the spring 18 to be compressed. Then, the elastic potential energy of the spring 18 can pass through the support plate 10 to make the copper contact 11 tightly contact the power source, ensuring good contact and reducing the probability of arcing.

[0026] Working principle:

[0027] As shown in Figures 1-4, during use, after the copper contact 11 contacts the power source, it further pushes the base 1, causing the spring 18 to be compressed. The elastic potential energy of the spring 18 then passes through the support plate 10 to ensure the copper contact 11 is firmly in contact with the power source. When the copper contact 11 is in contact with the power source, the current flows through the copper contact 11, connecting block 12, slider 13, flexible wire 9, receiving wire 8, winding wire 6, and output wire 7 to other electronic components for use. After the copper contact 11 separates from the power source, the generated electric arc will travel along the copper contact 11 and connecting block 12... The permanent magnet ring 4 is circular, with a spiral heat sink 5 on it. This helps to distribute the magnetic field evenly around the ring. Through the action of the magnetic field, the permanent magnet ring 4 can generate a Lorentz force on the electric arc, deflecting the arc's trajectory and reducing the duration of the arc between the contact point or the conductive path. At the same time, the spiral heat sink 5 is designed on the surface of the permanent magnet ring 4 to ensure that the arc can quickly contact the cooling surface for heat exchange when it occurs. The arc can be quickly extinguished by the dispersion of the magnetic field and the cooling area.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
