Description

Technical Field

[0001] This application relates to the field of cable protection device technology, and in particular to a cable joint protection device. Background Technology

[0002] In the power grid sector, to ensure personal and equipment safety, electrical equipment needs to be grounded so that any additional current generated by the equipment during operation, such as short circuits or lightning strikes, can be diverted to the ground.

[0003] In related technologies, a grounding grid is installed in the stratum, and down conductors are installed on the electrical equipment. The down conductors are connected to the connecting conductors in the grounding grid to ground the electrical equipment. The down conductors and connecting conductors are connected by welding. Since the welding position is located underground, the welding point is in a humid environment.

[0004] Therefore, in related technologies, there is a technical problem that the connection between the down conductor and the connecting conductor is easily corroded, leading to unreliable grounding performance of electrical equipment. Utility Model Content

[0005] This application provides a cable joint protection device, which aims to solve the technical problem that the connection between the down conductor and the connecting conductor is easily corroded, resulting in unreliable grounding performance. The device improves the corrosion resistance of the cable connection, thereby improving the reliability of the electrical connection between cables and thus improving the grounding reliability of electrical equipment.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application provides a cable connector protection device, including:

[0008] The housing assembly includes two opposing conductive housings and a connecting bridge. The first sides of the two conductive housings are connected by the connecting bridge, and the second sides of the two conductive housings are detachably connected so that the two conductive housings together enclose a receiving cavity.

[0009] In this embodiment, by providing a housing assembly on the outer periphery of the weld between the down conductor and the connecting conductor, the weld is physically isolated from the surrounding environment, preventing moisture from the surrounding environment from directly contacting and corroding the weld. This improves the corrosion resistance of the weld, enhances the reliability of the electrical connection between the down conductor and the connecting conductor, and consequently improves the grounding reliability of the electrical equipment connected to the down conductor. Simultaneously, by setting the housing assembly as a conductive housing, both the down conductor and the connecting conductor can dissipate current to the surrounding environment through the housing assembly. Furthermore, the housing assembly increases the contact area between the connection point of the down conductor and the connecting conductor and the surrounding environment, thereby improving the current dissipation efficiency of the down conductor and the connecting conductor during the current dissipation process.

[0010] In some embodiments, the conductive housing includes a first housing portion and a second housing portion disposed at both ends of the first housing portion, wherein the cross-sectional dimension of the second housing portion gradually decreases in the direction away from the first housing portion.

[0011] With this configuration, the second housing is designed to form a closed opening, which secures the cable passing through the accommodating cavity to the second housing, thereby preventing the cable connector protection device from slipping from the cable connection point to other locations.

[0012] In some embodiments, the conductive housing further includes a flexible portion disposed at one end of the second housing portion away from the first housing portion.

[0013] This design further strengthens the fixing effect of the cable joint protection device on both ends of the down conductor and the connecting conductor, reduces the force exerted by the twisting of the down conductor and the connecting conductor on the weld joint, thereby reducing the damage rate of the weld joint of the down conductor and the connecting conductor, and further improving the reliability of the cable joint protection device for cable protection.

[0014] In some embodiments, both the first housing portion and the second housing portion comprise at least nickel and epoxy resin; and / or,

[0015] The flexible part includes one of polyethylene, EPDM rubber, and chloroprene rubber.

[0016] With this configuration, both the first and second housing portions include at least nickel and epoxy resin, ensuring sufficient support strength while improving conductivity and facilitating electrical conductivity between the welded joints of the down conductor and the connecting conductor. The flexible portion includes one of polyethylene, EPDM rubber, or neoprene rubber, allowing it to deform without damage as the down conductor and the connecting conductor twist, thus preventing the cable connector protection device from being in a hard-on-hard contact with the down conductor and the connecting conductor, which could damage them.

[0017] In some embodiments, along the connection direction of the two conductive housings, the cross-sectional dimension of the connecting bridge near the middle is smaller than the cross-sectional dimensions at both ends of the connecting bridge.

[0018] This design ensures the connection strength between the connecting bridge and the two conductive shells while reducing the force that could deform the connecting bridge, making the installation of the cable joint protection device more convenient and quick.

[0019] In some embodiments, the two conductive housings and the connecting bridge are integral components.

[0020] This design simplifies the structure of the cable protection device and makes installation easier and faster.

[0021] In some embodiments, one of the two conductive housings has a protrusion structure with an injection hole that communicates with the accommodating cavity.

[0022] This design allows for the injection of colloid into the accommodating cavity, expelling air from the cavity and preventing the welded joints of the down conductor and the connector from being exposed to a humid environment within the cavity. This further enhances the corrosion resistance and electrical connection reliability of the welded joints, thereby improving the reliability of the cable joint protection device in protecting the cable connection.

[0023] In some embodiments, at least one of the two conductive housings has an exhaust port.

[0024] This design facilitates the expulsion of air from the cavity during the glue injection process, making the injection process smoother.

[0025] In some embodiments, a first snap-fit ​​portion is provided on the second side of one conductive housing, and a second snap-fit ​​portion is provided on the second side of another conductive housing, wherein the first snap-fit ​​portion snaps into the second snap-fit ​​portion.

[0026] This design improves the reliability of the connection and sealing between the two conductive housings, thereby enhancing the reliability of the cable joint protection device in protecting the cable from corrosion.

[0027] In some embodiments, the flexible portion has a fixing portion, and the cable connector protection device further includes a fastener, which fixes the two corresponding flexible portions together via the two corresponding fixing portions.

[0028] This design further improves the reliability of the connection and sealing between the two conductive shells, thereby further enhancing the reliability of the cable joint protection device for cable corrosion protection.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of 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 application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] In the power grid sector, to ensure personal and equipment safety, electrical equipment needs to be grounded so that any additional current generated by the equipment during operation, such as short circuits or lightning strikes, can be diverted to the ground.

[0051] To ground electrical equipment, a grounding grid is installed in the ground. Down conductors are connected to the electrical equipment, and these down conductors are connected to the grounding grid's connecting conductors. This allows any extra current generated by the electrical equipment to be dissipated into the earth through the down conductors, connecting conductors, and the grounding grid. The down conductors and connecting conductors are connected by welding. Since the welding point is underground and in a humid environment, there is a technical problem: the connection between the down conductors and connecting conductors is prone to corrosion, leading to unreliable grounding performance of the electrical equipment.

[0052] To address the aforementioned technical problems, this application provides a cable joint protection device to improve the corrosion resistance of cable connections, thereby enhancing the reliability of electrical connections between cables and ultimately improving the grounding reliability of electrical equipment.

[0053] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0054] See attached image. Figure 1 A schematic diagram of a cable connector protection device provided in an embodiment of this application; Figure 2 for Figure 1 A schematic diagram of a structure at point AA; Figure 3 for Figure 1 A schematic diagram of a structure at point BB; Figure 4 for Figure 3 A magnified view of a section at point C.

[0055] Combination Figure 1 , Figure 2 and Figure 3 As shown, the cable connector protection device 10 includes a housing assembly 100.

[0056] The housing assembly 100 includes two opposing conductive housings 110 and a connecting bridge 120. The first sides of the two conductive housings 110 are connected via the connecting bridge 120, and the second sides of the two conductive housings 110 are detachably connected, so that the two conductive housings 110 together form a receiving cavity to accommodate the connection point of two cables. For example, the receiving cavity is used to accommodate the solder joint between the down conductor and the connecting conductor, thereby physically isolating the solder joint from the surrounding environment. The detachable connection of the second sides of the two conductive housings 110 facilitates easy inspection of the solder joint between the down conductor and the connecting conductor, as well as maintenance and replacement of the cable joint protection device 10.

[0057] For example, along the cable extension direction, the cross-sectional shape of the conductive housing 110 can be semi-circular, semi-elliptical, semi-square, polygonal, etc., so that after the two sides of the conductive housing 110 are connected accordingly, an accommodating cavity is formed.

[0058] In this embodiment, by providing a housing assembly 100 on the outer periphery of the weld joint between the down conductor and the connecting conductor, the weld joint is physically isolated from the surrounding environment, preventing moisture from the surrounding environment from directly contacting the weld joint and causing corrosion. This improves the corrosion resistance of the weld joint, enhances the reliability of the electrical connection between the down conductor and the connecting conductor, and consequently improves the grounding reliability of the electrical equipment connected to the down conductor. Simultaneously, by setting the housing assembly 100 as a conductive housing, both the down conductor and the connecting conductor can dissipate current to the surrounding environment through the housing assembly 100. Furthermore, the housing assembly 100 increases the contact area between the connection joint of the down conductor and the connecting conductor and the surrounding environment, thereby improving the current dissipation efficiency of the down conductor and the connecting conductor during the current dissipation process.

[0059] Furthermore, such as Figure 1 and Figure 2 As shown, the conductive housing 110 includes a first housing portion 111 and second housing portions 112 disposed at both ends of the first housing portion 111. The cross-sectional dimensions of the second housing portion 112 gradually decrease in the direction away from the first housing portion. The first housing portion 111 is mainly used to form a larger accommodating cavity to accommodate different cable sizes and improve the versatility of the cable connector protection device 10. The second housing portion 112 is designed to form a constricted opening, securing the cable passing through the accommodating cavity to the second housing portion 112, thereby preventing the cable connector protection device 10 from slipping from the cable connection point to other locations.

[0060] For example, the first housing portion 111 and the second housing portion 112 are made of rigid polymer conductive material. Specifically, both the first housing portion 111 and the second housing portion 112 include at least nickel and epoxy resin. That is, the first housing portion 111 and the second housing portion 112 can be prepared by injection molding or compression molding of a material mixed with epoxy resin and nickel powder. Alternatively, the first housing portion 111 and the second housing portion 112 can also be prepared by mixing epoxy resin and carbon fiber, epoxy resin and copper powder, phenolic resin and graphite, phenolic resin and conductive carbon black, conductive nylon and glass fiber, or conductive nylon and carbon fiber. This ensures that the first housing portion 111 and the second housing portion 112 have sufficient supporting strength while improving conductivity, facilitating conductivity to the external environment at the lead wire and the solder joint of the connector.

[0061] In addition, such as Figure 1 and Figure 2 As shown, the conductive housing 110 also includes a flexible portion 113, which is disposed at the end of the second housing portion 112 away from the first housing portion 111. The second housing portion 112 has a closing function, and the flexible portion 113 further strengthens the fixing effect of the cable joint protection device 10 on the down conductor and the connecting conductor, further tightens the down conductor and the connecting conductor, reduces the force exerted by the twisting of the down conductor and the connecting conductor on the weld joint, thereby reducing the damage rate of the weld joint of the down conductor and the connecting conductor, and further improving the reliability of the cable joint protection device 10 in protecting the cable.

[0062] For example, the flexible part 113 includes one of polyethylene, EPDM rubber, and neoprene rubber. Therefore, the flexible part 113 is provided so that it can deform without being damaged as the down conductor and the connecting conductor twist, thereby avoiding a hard-on-hard contact between the two ends of the cable joint protection device 10 and the down conductor and the connecting conductor, which would cause damage to the down conductor and the connecting conductor.

[0063] The flexible part 113 and the second housing part 112 are fixedly connected. The fixed connection can be achieved by bonding, bolt and nut connection, snap-fit ​​connection, etc.

[0064] In addition, combined Figure 3 and Figure 4 As shown, along the connection direction of the two conductive housings 110, the cross-sectional dimension of the connecting bridge 120 near the middle is smaller than the cross-sectional dimensions of the two ends of the connecting bridge 120.

[0065] It should be noted that during the process of fastening the cable connector protection device 10 to the down conductor and the connector, the middle part of the connecting bridge 120 needs to be bent and deformed so that the cable connector protection device 10 changes from its initial state. Figure 1The state shown is that the first sides of the two conductive housings 110 are only connected by the connecting bridge 120. After the connecting bridge 120 is deformed, it changes to a state in which the two conductive housings 110 are arranged correspondingly and the second sides of the two conductive housings 110 are also connected.

[0066] Therefore, along the connection direction of the two conductive housings 110, the cross-sectional dimension of the connecting bridge 120 near the middle is smaller than the cross-sectional dimensions of the two ends of the connecting bridge 120. This makes the connecting bridge 120 easier to bend during the process of the two conductive housings 110 being fastened to the cable connection. Furthermore, the larger the dimensions at both ends of the connecting bridge 120, the stronger the connection between the connecting bridge 120 and the two conductive housings 110. The smaller the dimension in the middle of the connecting bridge 120, the less force can be used to fasten the two conductive housings 110 together, making the installation of the cable connector protection device 10 more convenient and quick.

[0067] It should be noted that the material of the connecting bridge 120 is the same as that of the first housing part 111 and the second housing part 112, and the first housing part 111, the second housing part 112 and the connecting bridge 120 can be manufactured together.

[0068] Therefore, in some specific embodiments, the two conductive housings 110 and the connecting bridge 120 are integrated as a single piece. This is achieved through injection molding or compression molding, a simpler and more convenient manufacturing process. This reduces the installation steps of connecting the first housing part 111, the second housing part 112, and the connecting part together, resulting in a simpler structure and easier, faster installation of the cable connector protection device 10.

[0069] like Figure 1 , Figure 2 and Figure 3 As shown, one of the two conductive housings 110 has a protruding structure 114, and the protruding structure 114 has an injection hole 115, which communicates with the accommodating cavity. When the two conductive housings 110 are fastened to the connection between the down conductor and the connecting conductor, glue is injected into the accommodating cavity through the injection hole 115 to expel air from the accommodating cavity and prevent the welding joint of the down conductor and the connecting conductor from being in a humid environment in the accommodating cavity. This further improves the corrosion resistance and electrical connection reliability of the welding joint of the down conductor and the connecting conductor, thereby further improving the reliability of the cable joint protection device 10 in protecting the cable connection.

[0070] For example, the colloid injected into the accommodating cavity can be a mixture of nickel powder and epoxy resin, a mixture of silicone resin and graphite powder, a mixture of hydrolysis-resistant polyurethane and nickel-plated graphite, etc. The colloid has conductive properties, will not affect the lead wire and the lead wire solder joint, and dissipates current to the external environment.

[0071] In another example, the axial cross-sectional shape of the protrusion structure 114 can be circular, square, polygonal, etc. The protrusion structure 114 is provided so that during the process of injecting the colloid into the accommodating cavity, the dispensing device will not penetrate into the space of the accommodating cavity, thereby increasing the amount of colloid injected into the accommodating cavity and improving the reliability of dispensing the colloid into the accommodating cavity. In addition, the protrusion structure 114 also has a guiding effect on the flow of the colloid, so that the colloid entering the accommodating cavity can flow evenly in all directions, thereby improving the uniformity of the colloid injected into the accommodating cavity.

[0072] Furthermore, such as Figure 1 As shown, at least one of the two conductive housings 110 has a vent 116 so that air in the receiving cavity is discharged from the vent 116 during the process of injecting adhesive into the receiving cavity, making the injection process smoother.

[0073] For example, the number of vent holes 116 can be two, three, four, five, six, etc. Both the vent holes 116 and the protrusion structure 114 can be set on the same conductive housing 110. Because the glue injection process is performed from top to bottom, after the cable connector protection device 10 is fastened to the connection between the lead wire and the connecting wire, the protrusion structure 114 can be manually controlled to face upwards, so that the vent holes 116 set on the same conductive housing 110 as the protrusion structure 114 also face upwards, which is more conducive to the gas in the accommodating cavity being discharged through the vent holes 116.

[0074] In some specific embodiments, such as Figure 1 As shown, one conductive housing 110 has a first snap-fit ​​portion 117 on its second side, and the other conductive housing 110 has a second snap-fit ​​portion 118 on its second side. The first snap-fit ​​portion 117 and the second snap-fit ​​portion 118 snap together. The arrangement of the first snap-fit ​​portion 117 and the second snap-fit ​​portion 118 makes the detachable connection between the second sides of the two conductive housings 110 simple and quick, facilitating the installation of the cable connector protection device 10. Furthermore, the arrangement of the first snap-fit ​​portion 117 and the second snap-fit ​​portion 118 improves the connection reliability and sealing reliability between the two conductive housings 110, thereby improving the reliability of the cable connector protection device 10 in protecting cables from corrosion.

[0075] Furthermore, the first latching portion 117 and the second latching portion 118 are respectively disposed on the same side of the first connecting portion of the two conductive housings 110. For example, combined with Figure 1 and Figure 3 As shown, the first snap-fit ​​part 117 is one of a buckle and a snap-fit ​​hole, and the second snap-fit ​​part 118 is the other of a buckle and a snap-fit ​​hole. When the two conductive shells 110 are snapped together, the buckle and the snap-fit ​​hole engage to fix the two conductive shells 110 together. The buckle and the snap-fit ​​hole engage in a simple structure that is easy to implement.

[0076] Furthermore, such as Figure 1 As shown, the flexible part 113 has a fixing part 119. The cable connector protection device 10 also includes fasteners. The fasteners fix the two corresponding flexible parts 113 together via the two corresponding fixing parts 119. This further fixes the two conductive shells 110 together, further improving the connection reliability and sealing reliability between the two conductive shells 110, and thus further improving the reliability of the cable connector protection device 10 in protecting the cable from corrosion.

[0077] For example, the fixing part 119 is a protruding through hole provided on the flexible part 113, and the fastener is a cable tie. When the two conductive housings 110 are fastened together, the cable tie is passed through the protruding through hole on the flexible part 113 provided on the same end of the two conductive housings 110 and tightened, thereby preventing air from entering the accommodating cavity from both ends of the cable joint protection device 10, so as to further improve the reliability of the cable joint protection device 10 in protecting the cable from corrosion.

[0078] Of course, the first snap-fit ​​portion 117 and the second snap-fit ​​portion 118 can also be replaced by a combination of protruding through holes and cable ties to fix the two first housing portions 111 together. Alternatively, bolts and nuts can be provided, and the first snap-fit ​​portion 117 and the second snap-fit ​​portion 118 can be replaced by bolt holes, and the two first housing portions 111 can be fixedly connected by bolt and nut connection.
