Protection assembly for cable and electronic device

Abstract

Embodiments of the present application provide a protection assembly for a cable and an electronic device. The electronic device comprises a conductor and an insulator. The conductor abuts against a cable and is grounded, so that a shielding layer of the cable can have the effect of shielding from signals and lightning strike currents. The melting point temperature of the conductor is lower than the carbonization temperature of an insulation layer of the cable. Thus, when leakage occurs in the cable, the conductor can melt before the insulation layer is carbonized, so that the insulator then abuts against the cable and cuts off the path of the leakage, thereby preventing the temperature from continuing to rise and having the effect of leakage protection.

Description

Cable protection components and electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202411032550.1, filed on July 29, 2024, entitled “Protective Components and Electronic Devices for Cables”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and more specifically to a protective component and electronic equipment for cables. Background Technology

[0003] The application scenarios of electronic equipment are very complex. When using cables on site, due to various problems such as uncertain cable length, construction workers often need to strip the cable on site (that is, strip the outer sheath of the cable, and sometimes also the inner shielding and insulation layers of the cable, which is usually called wire stripping).

[0004] In some cases, installation workers only need to strip the outer sheath. For example, when cables are connected to electronic devices via power connectors, the outer sheath needs to be removed, leaving the cable's shield, insulation, and conductor intact. The stripped cable's shield needs to be electrically connected to other conductors for grounding, thus shielding signals and allowing lightning strikes. However, due to varying skill levels among installation workers, some may damage the inner insulation during the sheath removal process. In this case, the cable conductor may come into contact with another grounded conductor, creating an abnormal leakage current. The heat generated by this leakage will accumulate in the contact area. Since the insulation layer has a low temperature tolerance, the accumulated heat will cause the surrounding insulation to carbonize due to the high temperature. As the leakage continues and the temperature rises further, the carbonization of the insulation will gradually intensify and spread, eventually posing a risk of open flames.

[0005] Currently, the industry commonly uses overcurrent protection devices on the power supply side to solve leakage problems. These devices activate when they detect a large current, cutting off the power supply to isolate the leakage fault. However, in the aforementioned cable leakage scenario, due to poor contact between the conductor and the mounting device, the resulting leakage current is small and insufficient to trigger the overcurrent protection device. Therefore, overcurrent protection devices cannot be used to solve this leakage problem. Summary of the Invention

[0006] This application provides a protection component and electronic device for cables, which can solve the problem that existing cables cannot stably provide both grounding and leakage protection after wiring.

[0007] Firstly, a protective component for a cable is provided, the cable including an insulation layer; the protective component includes: a conductor for contacting the cable and grounding; the melting point of the conductor is lower than the carbonization temperature of the insulation layer; and an insulator located on the side of the conductor away from the cable; the melting point of the insulator is higher than the melting point of the conductor, and the insulator is used to contact the cable when the conductor melts. A normally wired cable includes a conductor, an insulation layer, and a shielding layer from the inside out. At this time, the conductor of the protective component contacts the shielding layer of the cable and grounds, and the stable grounding of the shielding layer enables it to shield signals and conduct lightning current. If an abnormality in the wiring causes damage to the shielding layer and insulation layer, the conductor contacts the conductor of the cable, leading to a leakage fault. The temperature in the leakage area rises, and the conductor melts before the insulation layer carbonizes. Subsequently, the insulator contacts the conductor of the cable. The high temperature of the melting conductor does not affect the insulation performance of the insulator; therefore, the insulator cuts off the leakage current path, prevents the temperature from rising further, and thus avoids the problem of insulation layer carbonization, achieving the function of leakage protection.

[0008] In conjunction with the first aspect, in a first possible implementation of the first aspect, the protection component further includes: a base supporting the insulator; the base is made of a metal material and provides elasticity to allow the conductor or the insulator to abut and fix the cable. In this implementation, the protection component achieves the function of fixing the cable through the base. When the conductor is not melted, the elasticity of the base is transmitted to the conductor through the insulator, and the conductor abuts and fixes the cable; when the conductor melts, the elasticity of the base causes the insulator to abut and fix the cable. Furthermore, the elasticity provided by the base when fixing the cable can compress the cable, making it easier for conductors to be exposed in cables with damaged insulation. Therefore, integrating the insulator and conductor onto the base solves the installation and fixing problems of the insulator and conductor, provides accurate leakage protection for areas where the cable is prone to damage, and allows for miniaturization of the entire protection component, reducing costs and improving its applicability. Specifically, the base can be a clamp, clip, or other fixing device, fixing the cable through snap-fitting, crimping, or other methods. Metal materials can simultaneously meet the strength and elasticity required for fixing cables in the base. Optionally, the metal material is at least one of iron, steel, or copper alloy.

[0009] In conjunction with the first aspect and the first possible implementation of the first aspect, in the second possible implementation of the first aspect, the conductor is grounded by electrically connecting to the base. Specifically, one end of the conductor can bypass the insulator and be directly electrically connected to the base, or an additional intermediate conductive structure can be provided to connect both the conductor and the base. After the cable is grounded through the conductor and the base, the conductor will melt and break during leakage, and the insulator can isolate the base and the cable, thereby preventing the cable conductor from being electrically connected to the base and causing continuous leakage.

[0010] In conjunction with the first aspect, or any of the first to second possible implementations of the first aspect, in the third possible implementation of the first aspect, the melting point temperature of the conductor is 110-180℃; the melting point temperature of the insulator is 160-1200℃. The carbonization temperature of commonly used cable insulation layers is typically above 300℃. Therefore, the conductor within the aforementioned melting point temperature range can effectively melt before the insulation layer carbonizes, and the insulator can maintain good insulation performance even when the conductor melts due to overheating, thereby achieving the purpose of isolating leakage current and protecting the cable.

[0011] In conjunction with the first aspect, or any of the first to third possible implementations of the first aspect, in the fourth possible implementation of the first aspect, the material of the conductor includes at least one of bismuth, tin, indium, lead, or cadmium; and / or the material of the insulator includes at least one of polytetrafluoroethylene (PTFE), perfluoroalkoxy vinyl ether copolymer (PFA), perfluoroethylene propylene copolymer (FEP), ethylene-tetrafluoroethylene copolymer (ETFE), polypropylene (PP), ceramic, or mica sheet. These metals and their compositions have low melting points, allowing them to melt before the insulation layer carbonizes when used as conductors; these insulating materials have high melting points, enabling them to maintain good insulation properties even after the conductor melts, preventing electrical connection between the cable conductor and the conductor and / or metal base, thereby cutting off the leakage current path, preventing further temperature increases, avoiding insulation layer carbonization, and providing leakage protection.

[0012] In conjunction with the fourth possible implementation of the first aspect, in the fifth possible implementation of the first aspect, the material of the conductor also includes flux. Flux helps lower the melting point temperature of the conductor, making it easier for the melting point temperature of the conductor to fall below the carbonization temperature of the insulating layer. Specifically, the flux can be rosin, ammonium chloride, etc.

[0013] In conjunction with the first aspect, or any of the first to fifth possible implementations of the first aspect, in the sixth possible implementation of the first aspect, the conductor is fixed to the insulator by at least one of the following methods: bonding, spraying, plating, or embedding. In this implementation, the conductor can be sheet-like or layered, fixed to the insulator by bonding, or a groove can be formed on the insulator to embed the sheet-like or layered conductor into the groove; alternatively, conductive material powder can be sprayed onto the surface of the insulator by thermal spraying or other methods to form a conductive coating; or a conductive plating layer can be formed on the surface of the insulator by vacuum deposition, electroplating, or other methods. The above methods can form a stable conductive structure on the insulator, resulting in a high connection strength between the insulator and the conductor, making them difficult to separate during use.

[0014] In a seventh possible implementation of the first aspect, combining any of the first to sixth possible implementations, the insulator is fixed to the base by at least one of the following methods: bonding, spraying, coating, or sleeve application. In this implementation, the insulator can be sheet-like or layered and fixed to the base by bonding; it can also be sprayed onto the base by flame spraying, fluidized bed spraying, or electrostatic powder spraying; it can also be formed by preparing a suspension of the insulator material and coating the suspension onto the base to form an insulator coating; or the insulator material can be molded into a sleeve shape and then sleeved onto the base. Through these methods, the protective component of this implementation can be obtained using an existing base, reducing production costs. Simultaneously, the formed insulator structure is stable, the connection strength between the insulator and the base is high, and it is not easily separated during use.

[0015] In conjunction with the first aspect, or any of the third to seventh possible implementations of the first aspect, in the eighth possible implementation of the first aspect, the insulator further serves to provide elasticity to secure the cable. Specifically, the insulator can be manufactured into a structure similar to the aforementioned base through molding or other methods to meet the requirements for cable securing in certain scenarios. In this implementation, the protection component secures the cable through the insulator, eliminating the need for a metal base and reducing costs.

[0016] In a second aspect, an electronic device is provided, comprising: a cable; and a protection component, as described in the first aspect or any of the first to eighth possible implementations of the first aspect, for protecting the cable. The electronic device, through the aforementioned protection component, achieves both grounding of the cable's shielding layer and leakage protection, preventing damage to the electronic device from carbonization and fire caused by cable leakage.

It should be understood that the reference numerals are also applicable to other identical parts or components.

[0032] This application provides a protective component and electronic device for cables. The protective component of this application provides protection when the cable is secured after wiring. Referring to Figure 1, a typical cable 10 includes, from the inside out, a conductor 101, an insulation layer 102, a shielding layer 103, and a sheath 104. The conductor 101 can be made of conductive materials such as copper, silver, or aluminum. The insulation layer 102 can be made of materials such as polyvinyl chloride (PVC), polypropylene (PP), or polyethylene (PE). The shielding layer 103 can be made of braided metal wire or a metal film. The sheath 104 can be made of materials such as polyvinyl chloride (PVC), polyethylene (PE), polytetrafluoroethylene (PTFE), nylon, styrene-butadiene rubber (SBR), or nitrile rubber (NBR). The conductor 101 in the cable 10 serves as the transmission carrier of electrical signals. The insulation layer 102 protects the conductor 101 and also isolates the conductor 101 from the shielding layer 103. The shielding layer 103 is used to reduce the impact of external electromagnetic interference on signal transmission in conductor 101, and can also prevent signal leakage from conductor 101 from affecting surrounding equipment. The sheath 104, as the outermost protective layer of cable 10, can play a role in waterproofing, corrosion prevention, and protection against bending and mechanical damage.

[0033] It should be noted that, compared to the structure shown in Figure 1, the cable 10 can also have different numbers of structures. For example, the cable 10 can have multiple conductors 101, each conductor 101 having a corresponding insulation layer 102 and shielding layer 103, and multiple conductors 101, insulation layers 102, and shielding layers 103 are all disposed within an outer sheath 104. The cable 10 can also have more structures than those shown in Figure 1, for example, the cable 10 can have wrapping tape, filler, and other structures. It can be understood that the protection component 20 of this application is used for the cable 10 after wiring, that is, for the cable 10 after the sheath 104 has been stripped, exposing the insulation layer 102 and shielding layer 103, to provide grounding and leakage protection for the shielding layer 103. Therefore, the protection component 20 of this application is also applicable to these different structures of cable 10.

[0034] For ease of description, the cable 10 in the following embodiments refers to the cable 10 after wiring. The cable 10 after wiring includes a conductor 101, an insulation layer 102, and a shielding layer 103.

[0035] Referring to Figure 2, the protection component 20 of this application includes a conductor 201 and an insulator 202. The conductor 201 is grounded and is used to abut against the cable 10, while the insulator 202 is located on the side of the conductor 201 away from the cable 10.

[0036] Conductor 201 can be grounded in a variety of ways. For example, conductor 201 can be grounded by connecting to a ground wire. Or, when the protection component 20 is applied to certain equipment, conductor 201 can be grounded by connecting to the metal casing of the equipment. This embodiment does not limit the specific grounding method of conductor 201.

[0037] As shown in Figure 2, the cable 10 after normal wiring includes a conductor 101, an insulation layer 102, and a shielding layer 103 from the inside out. At this time, the conductor 201 of the protection component 20 abuts against the shielding layer 103 of the cable 10 and is grounded. The shielding layer 103 is stably grounded, thus enabling it to perform the functions of shielding signals and carrying lightning current.

[0038] Referring to Figure 3, when improper operation by on-site personnel causes damage to the shielding layer 103 and the insulation layer 102, the conductor 201 comes into contact with the conductor 101 of the cable 10, forming an electrical connection, and the conductor 101 is grounded. The current in the conductor 101 is conducted to the ground along the conductor 201, resulting in leakage. Due to poor contact between the conductor 101 and the conductor 201 at the contact point, the resistance is high, and significant heat will occur at the contact point. If not dealt with in time, the heat will continue to accumulate, causing the insulation layer 102 to carbonize and spread, ultimately posing a risk of open flame.

[0039] In this embodiment, the melting point of the conductor 201 is lower than the carbonization temperature of the insulation layer 102, and the melting point of the insulator 202 is higher than the melting point of the conductor 201. The insulator 202 is used to contact the cable 10 when the conductor 201 melts. Referring to Figure 4, when leakage occurs, the heat accumulated at the contact point will cause the conductor 201 to melt before the insulation layer 102 carbonizes. After the conductor 201 at the contact point melts, it will separate from the conductor 101. At the same time, since the melting point of the insulator 202 is higher than that of the conductor 201, the high temperature of the conductor 201 melting will not affect the insulation performance of the insulator 202. The insulator 202 can contact the conductor 101 of the cable 10 after the conductor 201 melts and block the leakage current, preventing the temperature from continuing to rise, thereby avoiding the problem of carbonization of the insulation layer 102 and playing the role of leakage protection.

[0040] In some embodiments, as shown in FIG5, the protective assembly 20 further includes a base 203 for supporting the insulator 202 and providing elasticity to allow the conductor 201 or the insulator 202 to abut against and fix the cable 10. The base 203 includes a mounting portion 2031 and an elastic fixing portion 2032 connected to the mounting portion 2031. The mounting portion 2031 is used to fix the base 203 to other components. The elastic fixing portion 2032 provides elasticity through deformation. When the cable 10 is placed in the elastic fixing portion 2032, the elastic fixing portion 2032 can slightly deform and compress the cable 10 to achieve fixation. The insulator 202 is disposed on the side of the elastic fixing part 2032 facing the cable 10, while the conductor 201 is disposed on the side of the insulator 202 facing the cable 10 and away from the elastic fixing part 2032. Therefore, the protection assembly 20 has a three-layer structure in the cross-sectional plane of the cable 10 shown in Figure 5. The three layers, from near to far from the cable 10, are the conductor 201, the insulator 202, and the base 203. When the conductor 201 is not melted, the elastic force provided by the base 203 is transmitted to the conductor 201 through the insulator 202, making the conductor 201 in close contact with the shielding layer 103 of the cable 10. The shielding layer 103 is well grounded, thus providing good shielding and meeting the high lightning current requirements. When the conductor 201 melts, the elastic force provided by the base 203 allows the insulator 202 to abut against and fix the cable 10 and block leakage current.

[0041] In this embodiment, the protection component 20 uses the base 203 to fix the cable 10. Furthermore, the elasticity provided by the base 203 when fixing the cable 10 can compress the cable 10, making it easier for the conductor 101 to be exposed in cables with damaged insulation 102. Therefore, integrating the insulator 202 and the conductor 201 onto the base 203 solves the installation and fixing problems of the insulator 202 and the conductor 201, accurately provides leakage protection to areas of the cable 10 prone to damage, and allows for miniaturization of the entire protection component 20, reducing costs and improving its applicability.

[0042] In Figure 5, the base 203 is an Ω-shaped wire clamp that secures the cable 10 by snap-fit. Referring to Figure 6, it can be understood that the base 203 can also be different types of fixing devices. For example, the base 203 can be a U-shaped wire clamp as shown in Figure 6(a), securing the cable 10 by snap-fit; or the base 203 can be an Ω-shaped buckle as shown in Figure 6(b), securing the cable 10 by crimping. This embodiment does not limit the specific shape of the base 203.

[0043] In this embodiment, the base 203 is made of metal. The metal material can simultaneously meet the strength and elasticity required for the base 203 to fix the cable 10. Optionally, the metal material is at least one of iron, steel or copper alloy.

[0044] In some embodiments, the conductor 201 is grounded by electrically connecting it to the base 203. Since the base 203 is made of metal and is fixed to other components via the mounting part 2031, grounding the base 203 is relatively easy. In this case, simply connecting the already grounded base 203 to the conductor 201 electrically achieves grounding of the conductor 201. Specifically, as shown in Figure 5, one end 2011 of the conductor can bypass the insulator 202 and be directly electrically connected to the base 203. Optionally, an additional intermediate conductive structure can be provided to connect both the conductor 201 and the base 203. For example, a wire can be provided, with both ends connected to the conductor 201 and the base 203 respectively; or metal rivets, screws, etc., can be used to penetrate and fix the conductor 201 and the insulator 202 to the base 203, achieving electrical connection between the conductor 201 and the base 203 through the rivets, screws, etc. After the cable 10 is grounded through the conductor 201 and the base 203, the conductor 201 will melt and break during the leakage process. The insulator 202 can isolate the base 203 and the cable 10, thereby preventing the conductor 101 of the cable 10 from being electrically connected to the base 203 and causing continuous leakage.

[0045] In some embodiments, the melting point temperature of the conductor 201 is 110-180°C; the melting point temperature of the insulator 202 is 160-1200°C. The carbonization temperature of the insulation layer 102 commonly used in cables 10 is typically above 300°C. Therefore, the conductor 201 within the aforementioned melting point temperature range can effectively melt before the insulation layer 102 carbonizes, and the insulator 202 can maintain good insulation performance even if the conductor 201 melts due to overheating, thereby achieving the purpose of isolating leakage current and protecting the cable 10. In some specific embodiments, the material of the conductor 201 includes at least one of bismuth, tin, indium, lead, or cadmium. These metals and their combinations have low melting points, and the melting point temperature can be controlled within 110-180°C. Using these metals and their combinations as the conductor 201 allows it to melt before the insulation layer 102 carbonizes, ensuring that the grounding of the disconnected shielding layer 103 is achieved. Furthermore, the material of the conductor 201 also includes flux. Flux can help lower the melting point temperature of the conductor 201, making it easier to control the melting point temperature of the conductor 201 between 110-180°C. Specifically, the flux can be a resin flux such as rosin and / or an inorganic flux such as ammonium chloride. In some specific embodiments, the material of the insulator 202 includes at least one of polytetrafluoroethylene (PTFE), perfluoroalkoxy vinyl ether copolymer (PFA), perfluoroethylene propylene copolymer (FEP), ethylene-tetrafluoroethylene copolymer (ETFE), polypropylene (PP), ceramic, or mica sheet. These insulator materials have high melting point temperatures and can maintain good insulation properties even after the conductor 201 melts, preventing the conductor 101 of the cable 10 from being electrically connected to the conductor 201 and / or the metal base 203, thereby cutting off the leakage current path, preventing the temperature from continuing to rise, avoiding carbonization of the insulation layer 102, and playing a role in leakage protection.

[0046] In some embodiments, the conductor 201 is fixed to the insulator 202 by at least one method, such as bonding, spraying, plating, or embedding. In this embodiment, the conductor 201 can be sheet-like or layered, fixed to the insulator 202 by bonding, or a groove can be formed on the insulator 202 to embed the sheet-like or layered conductor 201 into the groove; alternatively, the material powder of the conductor 201 can be sprayed onto the surface of the insulator 202 by thermal spraying or other methods to form a conductor 201 coating; or a conductor 201 plating can be formed on the surface of the insulator 202 by vacuum coating, electroplating, or other methods. The above methods can form a stable conductor 201 structure on the insulator 202, with high connection strength between the insulator 202 and the conductor 201, making it difficult to separate during use. It can be understood that in this embodiment, it is only necessary to cover the insulator 202 at the contact position of the cable 10 with the conductor 201 to achieve the effect of grounding and leakage protection of the shielding layer 103. Therefore, when the conductor 201 is fixed on the insulator 202, the conductor 201 can completely cover the insulator 202; or the conductor 201 can only cover a local area on the insulator 202, and the conductor 201 in that local area contacts the shielding layer 103 of the cable 10 during subsequent use.

[0047] In some embodiments, the insulator 202 is fixed to the base 203 by at least one of the following methods: bonding, spraying, coating, or sleeve application. Optionally, the insulator 202 can be sheet-like or layered and fixed to the base 203 by bonding. Optionally, the insulator 202 can also be fixed by flame spraying, fluidized bed spraying, or electrostatic powder spraying. Optionally, a suspension of the insulator 202 material can be prepared and coated onto the base 203 to form an insulator 202 coating. Optionally, the insulator 202 material can be molded into a sleeve shape and then sleeved onto the base 203. This embodiment can obtain the protective component 20 by processing the existing base 203 in the above ways, reducing production costs. At the same time, the resulting insulator 202 structure is stable, and the connection strength between the insulator 202 and the base 203 is high, making it difficult to separate during use. It is understood that in this embodiment, simply covering the base 203 at the contact point of the cable 10 with the insulator 202 is sufficient to prevent the conductor 101 of the cable 10 from becoming electrically connected to the base 203 and causing continuous leakage after the conductor 201 melts and breaks. Therefore, when the insulator 202 is fixed on the base 203, it can completely cover the base 203; or it can only cover a local area of ​​the base 203, with that local area serving as the contact point of the cable 10 during subsequent use.

[0048] In one specific embodiment, as shown in FIG7, the insulator 202 is sleeve-shaped. The insulator 202 has a certain elasticity, so it can be stably sleeved on the elastic fixing part 2032 of the base 203. Optionally, the inner contour of the sleeve-shaped insulator 202 is similar to but slightly smaller than the shape of the elastic fixing part 2032 of the base 203, so that the insulator 202 is subjected to uniform force and is not easily damaged, and the sleeve is more stable. The conductor 201 can be more closely and stably fixed to the uneven outer surface of the sleeve-shaped insulator 202 by spraying. In this embodiment, the insulator 202 includes a sleeve-shaped body 2021 and an extension 2022 connected to the edge of the body 2021. The conductor 201 can extend from the body 2021 to cover the extension portion 2022. Subsequently, the extension portion 2022 can be fixed to the base 203 or other conductive structures by metal rivets, screws, etc. The conductor 201 is grounded by being electrically connected to the base 203 or other conductive structures through rivets and screws.

[0049] In some embodiments, as shown in FIG8, the base 203 is not provided in the protection component 20, and the insulator 202 is also used to provide elasticity to fix the cable 10. Specifically, one or more materials with relatively high hardness and a certain degree of elasticity can be selected from commonly used insulating materials such as plastics, resins, and ceramics as the material of the insulator 202. The mounting part 2031 and the elastic fixing part 2032, similar to those in the aforementioned base 203, can be processed by molding or other methods to meet the requirements for fixing the cable 10 in some scenarios. In this embodiment, the protection component 20 fixes the cable 10 by the insulator 202, eliminating the need for the metal base 203 and reducing costs.

[0050] Some embodiments of this application also relate to an electronic device 30. As shown in FIG9, the electronic device 30 includes a cable 10 and a protection component 20 of any of the aforementioned embodiments. The protection component 20 is used to protect the cable 10, so as to achieve the effect of grounding and leakage protection of the shielding layer 103 of the cable 10, and to prevent the cable 10 from carbonizing and catching fire after leakage, thus preventing damage to the electronic device 30. Optionally, the electronic device 30 includes a metal housing 301. When the protection component 20 uses a base 203 to fix the cable 10, the mounting part 2031 of the base 203 can be fixed to the metal housing 301 by means of connectors 2033 such as rivets and screws. The conductor 201 of the protection component 20 is electrically connected to the base 203 and the metal housing 301 to achieve grounding.
