Abstract
Description
Technical Field
[0001] This application relates to the field of electrical auxiliary tools technology, and in particular to a magnetic connecting wire. Background Technology
[0002] In electrical cabinet maintenance, it is often necessary to test components such as relays. For example, spray marking requires frequent short-circuiting. Frequent disconnection and reconnection can easily damage the threaded parts of the terminals, causing stripping and unstable connections, which affects the normal operation of electrical equipment. In addition, some terminals have narrow openings, making it difficult to install multiple wires, resulting in excessively long disconnection and reconnection processes, reducing maintenance efficiency, increasing equipment downtime, and causing economic losses. Summary of the Invention
[0003] The purpose of this application is to provide a magnetic connector to solve the problems in the prior art where frequent disconnection and reconnection of terminals is required during electrical cabinet maintenance, which can easily lead to terminal damage, and where the bridging efficiency is low when the terminal position is narrow.
[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0005] This application provides a magnetic connector, comprising: a conductor, at least one end of which is connected to a magnetic contact, and an insulating shell disposed on the circumferential sidewall of the conductor and the magnetic contact. The magnetic contact includes: a male end with an end face protruding from the end face of the insulating shell, or a female end with an end face retracted into the insulating shell.
[0006] The male connector is designed to be attracted to the electrical cabinet terminal block to electrically connect the wire to the electrical cabinet terminal block; the female connector is designed to be attracted to the male connector to electrically connect the female connector to the male connector.
[0007] In this solution, magnetic contacts are used to connect the electrical cabinet terminals, achieving electrical connection between the wires and the terminals. This avoids damage to the terminals caused by frequent disconnection and reconnection during electrical cabinet maintenance. When the terminal space is confined, the magnetic contacts can use their own magnetism to enter the narrow space and connect to the terminal, accelerating the bridging process and improving the maintenance efficiency of electrical equipment. Furthermore, to meet different bridging length requirements, this solution provides both male and female magnetic contacts. The male contact's end face protrudes from the insulating shell and is suitable for connecting to the electrical cabinet terminals; the female contact's end face is retracted into the insulating shell and is suitable for attracting the male contact, enabling electrical connection between them. By connecting the male and female contacts, multiple magnetically connected wires can be spliced together to meet long-distance bridging between electrical cabinet terminals.
[0008] Optionally, the male connector includes: a first magnetic element and a first conductive element, the first conductive element being electrically connected to the wire, and the first magnetic element being adapted to attract the electrical cabinet terminal block so that the first conductive element is electrically connected to the electrical cabinet terminal block; the female connector includes: a second magnetic element and a second conductive element, the second conductive element being electrically connected to the wire, and the second magnetic element being adapted to attract the first magnetic element so that the second conductive element is electrically connected to the first conductive element.
[0009] Optionally, the first magnetic attractor and the second magnetic attractor are made of neodymium iron boron.
[0010] Optionally, the first conductive element is a copper layer wrapped around the first magnetic element, and the second conductive element is a copper layer wrapped around the second magnetic element.
[0011] In this design, the first and second magnetic components are made of neodymium iron boron (NdFeB). NdFeB possesses high magnetic strength, providing sufficient magnetic attraction force. For common iron or steel electrical cabinet terminals, NdFeB can strongly attract them, ensuring stability during the connection process. Furthermore, the high-temperature resistance of NdFeB allows it to maintain its attraction force even in various harsh working environments. Further, in this design, the first conductive component is a copper layer encasing the first magnetic component; the second conductive component is a copper layer encasing the second magnetic component. Thanks to the high magnetism of NdFeB, the copper layer can be pressed and fixed between the first magnetic component and the electrical cabinet terminal, or between the second magnetic component and the first magnetic component. Moreover, by completely encasing the NdFeB with a copper layer, it is ensured that when the magnetic contact is attracted and connected to the electrical cabinet terminal, the conductive copper layer is connected to the electrical cabinet terminal.
[0012] Optionally, the copper layer is soldered to the wire.
[0013] Optionally, the wire is made of oxygen-free copper.
[0014] Because high temperatures can cause NdFeB magnets to demagnetize, they are typically difficult to connect to wires via soldering. Conventional methods usually involve adhesive bonding or press-fitting. Adhesive bonding to wires results in poor stability, while press-fitting is a complex process. This solution encapsulates the NdFeB magnet in copper before soldering it to the wire, thus securing the NdFeB and enhancing the overall structural stability of the magnetic connection wire. Furthermore, the manufacturing process is simple.
[0015] Optionally, the protrusion distance of the male end face relative to the end face of the insulating shell is the same as the indentation distance of the female end face relative to the end face of the insulating shell.
[0016] Optionally, when only one end of the conductor is connected to a magnetic contact, the other end of the conductor is electrically connected to a lug. The magnetic connector in this design is suitable for terminal connections within a single electrical cabinet.
[0017] Optionally, the insulating shell is made of polyvinyl chloride (PVC). PVC has excellent electrical insulation properties, effectively preventing electric shock accidents caused by poor contact or external short circuits. At the same time, the PVC shell has high impact resistance and abrasion resistance, protecting the internal magnetic contacts and wires from physical damage. The shell also serves to waterproof and dustproof, further improving the service life and stability of the connecting cable.
[0018] Compared with existing technologies, the beneficial effects achieved by this application are as follows: This application uses magnetic contacts to connect electrical cabinet terminals, achieving electrical connection between wires and electrical cabinet terminals, avoiding damage to terminals caused by frequent disconnection and reconnection during electrical cabinet maintenance. When the terminal space is confined, the magnetic contacts can enter the narrow space and connect to the terminal through their own magnetic force, accelerating the bridging speed and improving the maintenance efficiency of electrical equipment. Furthermore, to meet the bridging length requirements in different situations, this application's magnetic contacts have both male and female types. The male contact's end face protrudes from the end face of the insulating shell, suitable for connecting to electrical cabinet terminals; while the female contact's end face is retracted into the insulating shell, suitable for attracting the male contact, enabling electrical connection between the female and male contacts. By connecting the male and female contacts, multiple magnetic connecting wires can be spliced to meet long-distance bridging between electrical cabinet terminals. Attached Figure Description

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.
[0026] Example 1
[0027] This embodiment describes a magnetic connector wire, see reference. Figure 1 and Figure 2 The magnetic connector in this embodiment includes a conductor 1 made of oxygen-free copper. At least one end of the conductor 1 is connected to a magnetic contact with strong magnetism, enabling it to attract and connect to common iron or steel electrical cabinet terminals. Connecting the electrical cabinet terminals via the magnetic contact allows for electrical connection between the conductor 1 and the terminals, avoiding damage caused by frequent disconnection and reconnection during electrical cabinet maintenance. Furthermore, in confined spaces, the magnetic contact can use its own magnetic force to enter the narrow space and connect to the terminal, accelerating the bridging process and improving the maintenance efficiency of electrical equipment. The magnetic connector in this embodiment is suitable for temporary wiring; for example, during electrical cabinet troubleshooting, if the machinery driven by the solenoid valve cannot be restored in a short time, to maintain production, the solenoid valve can be temporarily connected in parallel with another solenoid valve using the magnetic connector in this embodiment to avoid stripping the threads caused by frequent disconnection and reconnection of the terminal bolts.
[0028] refer to Figure 3 and Figure 4 Furthermore, when only one end of conductor 1 is connected to a magnetic contact, the other end of conductor 1 is electrically connected to a lug 5 to facilitate connection to a single electrical cabinet terminal block. In some cases, the material of the electrical cabinet terminal block is non-magnetic, and it can also be electrically connected to it via lug 5. By combining multiple magnetic connecting wires, various application environments can be met.
[0029] Furthermore, an insulating shell 2 is provided on the circumferential sidewalls of the conductor 1 and the magnetic contact. The insulating shell 2 is made of polyvinyl chloride (PVC), which has excellent electrical insulation properties and can effectively prevent electric shock accidents caused by poor contact or external short circuits. At the same time, the PVC shell has high impact resistance and abrasion resistance, which can protect the internal magnetic contact and conductor 1 from physical damage. The shell also serves to waterproof and dustproof, further improving the service life and stability of the connecting wire.
[0030] To meet the bridging length requirements in different situations, in this embodiment, the magnetic contact includes a male connector 3 with its end face protruding from the end face of the insulating housing 2, or a female connector 4 with its end face retracted into the insulating housing 2. The protrusion distance of the end face of the male connector 3 relative to the end face of the insulating housing 2 is the same as the retraction distance of the end face of the female connector 4 relative to the end face of the insulating housing 2. The male connector 3 is suitable for attracting the electrical cabinet terminals to electrically connect the wire 1 to the electrical cabinet terminals. The female connector 4 is suitable for attracting the male connector 3 to electrically connect the female connector 4 to the male connector 3. By connecting the male connector 3 and the female connector 4, multiple magnetically connected wires can be spliced to meet the long-distance bridging requirements between electrical cabinet terminals.
[0031] Example 2
[0032] Based on the same inventive concept as Embodiment 1, refer to Figure 1 In this embodiment, the male connector 3 includes a first magnetic 31 and a first conductive element 32. The first conductive element 32 is electrically connected to the wire 1. The first magnetic 31 is adapted to attract the electrical cabinet terminal block, so that the first conductive element 32 is electrically connected to the electrical cabinet terminal block. (Reference) Figure 2 The female connector 4 includes a second magnetic chuck 41 and a second conductive element 42. The second conductive element 42 is electrically connected to the wire 1. The second magnetic chuck 41 is adapted to attract the first magnetic chuck 31, thereby electrically connecting the second conductive element 42 and the first conductive element 32. Both the first magnetic chuck 31 and the second magnetic chuck 41 are made of neodymium iron boron (NdFeB). NdFeB has high magnetic strength, providing sufficient magnetic attraction force. For common iron or steel electrical cabinet terminals, NdFeB can strongly attract them, ensuring stability during the connection process. Furthermore, the high-temperature resistance of NdFeB allows it to maintain its attraction force even in various harsh working environments.
[0033] Furthermore, in this embodiment, the first conductive element 32 is a copper layer wrapped around the first magnetic element 31; the second conductive element 42 is a copper layer wrapped around the second magnetic element 41. Thanks to the high magnetism of neodymium iron boron, the copper layer can be pressed and fixed between the first magnetic element 31 and the electrical cabinet terminal, or between the second magnetic element 41 and the first magnetic element 31. In addition, by completely wrapping the neodymium iron boron with a copper layer, it can be ensured that when the magnetic contact is attracted and connected to the electrical cabinet terminal, the conductive copper layer can be connected to the electrical cabinet terminal.
[0034] Because high temperatures can cause NdFeB to demagnetize, it is generally difficult to connect NdFeB to wire 1 by welding. Conventional methods typically involve adhesive bonding or press-fitting. Adhesive bonding between NdFeB and wire 1 results in poor stability, while press-fitting is a complex process. In this embodiment, the NdFeB is encased in a copper layer and then welded to wire 1 to secure it. This enhances the overall structural stability of the magnetic connection wire and simplifies the manufacturing process.
[0035] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
