Abstract
Description
Technical Field
[0001] This application relates to the technical field of grounding of electrical equipment, and in particular to a grounding device and grounding system. Background Technology
[0002] Electrical equipment refers to the general term for technical devices used in power systems for power generation, transformation, transmission, distribution, or utilization of electrical energy, encompassing all types of equipment from energy conversion to end-use applications. When electrical equipment operates, it generates electromagnetic fields, which in turn generate interference signals. Using shielded grounding technology can guide these interference signals to the ground, preventing them from interfering with other surrounding equipment or lines. It also prevents external electromagnetic fields from interfering with signals transmitted within the shielded wire, ensuring the stability and accuracy of signal transmission.
[0003] Currently, traditional electromagnetic shielding grounding devices typically employ a fixed structure design, making them suitable only for shielding wires of one specification and size. When different specifications and sizes of shielding wires need to be installed, different grounding devices must be replaced accordingly, causing inconvenience, time-consuming and labor-intensive shielding grounding installation operations. In addition, a large number of different grounding devices are required, leading to increased costs and difficulties in storing and managing the grounding devices. Utility Model Content
[0004] Therefore, it is necessary to provide a grounding device and grounding system to address the problems of inconvenient installation and operation, time-consuming and labor-intensive, high cost, and difficult storage and management of traditional technologies.
[0005] A first aspect of this application provides a grounding device comprising:
[0006] A wiring conduit, the cavity of which is used to install a shielded wire;
[0007] A connector mechanism, movably disposed at one end of the wiring conduit, for connecting to electrical equipment; and
[0008] An adjustable fastening mechanism is provided at one end of the wiring carrier tube away from the connector mechanism. The adjustable fastening mechanism includes a clamping component movably disposed on the wiring carrier tube and an actuating component movably disposed on the wiring carrier tube. The actuating component is driven to engage with the clamping component to drive the clamping component to extend into or retract from the cavity of the wiring carrier tube. The clamping component is used to clamp the shielding wire located in the cavity of the wiring carrier tube.
[0009] The grounding device in this solution is used to connect to electrical equipment to ground it. Employing shielded grounding technology, interference signals are introduced to the ground, preventing them from interfering with other surrounding equipment or lines. It also prevents external electromagnetic fields from interfering with the signals transmitted within the shielded wire, ensuring the stability and accuracy of signal transmission. In use, the shielded wire is threaded into the conduit, with the connection end of the shielded wire protruding from the end of the conduit equipped with the connector mechanism. Then, the actuating component is operated, driving the clamping component to press the shielded wire firmly, ensuring it is reliably fixed to the ground. In the wire carrier conduit; finally, assemble and connect the connector mechanism with the connecting conduit of the electrical equipment, so that the connecting end of the shielded wire is inserted into the connecting slot of the electrical equipment, thereby completing the wiring installation of the shielded wire and the electrical equipment; since the clamping component can move flexibly with the help of the actuating component, shielded wires of different specifications and sizes can be flexibly and reliably clamped and fixed by the clamping component when they are passed through the wire carrier conduit, so that the same grounding device can be used for the installation of shielded wires of different specifications and sizes. This not only makes the wiring operation convenient, labor-saving and efficient, but also eliminates the need to equip a large number of different grounding devices, effectively reducing costs, and solving the problem of difficult storage and management of grounding devices.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0037] See Figure 1 and Figure 2 The present application provides a grounding system 100, which includes an electrical device 30 and a grounding device 10. The electrical device 30 is provided with a connecting pipe 31 and a connecting groove 32. The connecting groove 32 is connected to the cavity of the connecting pipe 31. The connector mechanism 12 is connected and fixed to the connecting pipe 31. The end of the shielding wire 20, which is inserted in the wiring carrier pipe 11, extends into the connecting groove 32 to achieve grounding connection.
[0038] As is easily understood, the inside of the connecting groove 32 is equipped with a grounding metal component. After the shielding wire 20 extends into the connecting groove 32, it contacts the grounding metal component to form an electrical connection, thereby enabling the generated interference signal to be led out through the shielding wire 20.
[0039] For example, the electrical equipment 30 is rectangular in shape. Multiple connecting slots 32 and connecting pipes 31 are arranged side-by-side along the length of one of its rectangular surfaces, with each slot and pipe corresponding to the other. Each connecting pipe 31 has two symmetrically arranged mounting ears, which are connected to the mounting ears and the housing of the electrical equipment 30 using threaded components, thus fixing the connecting pipe 31 to the housing of the electrical equipment 30. This arrangement allows for the simultaneous installation of multiple shielded wires 20, further improving the shielding effect and reliability.
[0040] like Figure 1 As shown, in one embodiment, the grounding device 10 includes a wiring conduit 11, a connector mechanism 12, and an adjustable fastening mechanism 13.
[0041] The conduit 11 is used to install the shielded wire 20. As is easily understood, the shielded wire 20 includes a sheath, an insulation layer, and a core, which are nested sequentially from the outside in. The core is made of metal and is used to contact the grounded metal component in the connection slot 32 to conduct interference signals. The insulation layer provides insulation and shielding, preventing interference signals from affecting surrounding equipment during transmission. The sheath provides protection and aesthetics, enhancing the durability of the shielded wire 20.
[0042] The connector mechanism 12 is movably disposed at one end of the wiring carrier tube 11 and is used to connect with the electrical equipment 30. The adjustable fastening mechanism 13 is disposed at the end of the wiring carrier tube 11 away from the connector mechanism 12 and includes a clamping component 131 movably disposed on the wiring carrier tube 11 and an actuating component 132 movably disposed on the wiring carrier tube 11. The actuating component 132 is driven to cooperate with the clamping component 131 to drive the clamping component 131 to extend into or retract from the cavity of the wiring carrier tube 11. The clamping component 131 is used to clamp the shielding wire 20 located in the cavity of the wiring carrier tube 11.
[0043] It is understandable that the inner tube of the wiring conduit 11 is larger than the shielded wires 20 of various wire diameters (i.e. different specifications and sizes) commonly used in the market, thus enabling the installation of various shielded wires 20. This is a basic necessary condition for the grounding device 10 to have universality.
[0044] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: When the grounding device 10 of this solution is used, it is connected to the electrical equipment 30 to ground the electrical equipment 30. The grounding technology of the shielded wire 20 can introduce interference signals into the ground, avoiding interference to other surrounding equipment or lines. At the same time, it can also prevent external electromagnetic fields from interfering with the signals transmitted in the shielded wire 20, ensuring the stability and accuracy of signal transmission. In use, the shielded wire 20 is installed through the cavity of the wiring carrier 11, and the connection end of the shielded wire 20 is exposed from the end of the wiring carrier 11 where the connector mechanism 12 is installed. Then, the actuation component 132 is operated, which drives the clamping component 131 to move, so that the clamping component 131 clamps the shielded wire 20 to ensure that the shielded wire 20 is grounded. The shielded wire 20 is reliably fixed in the wiring carrier 11. Finally, the connector mechanism 12 is assembled and connected to the connecting pipe 31 of the electrical equipment 30, so that the connecting end of the shielded wire 20 is inserted into the connecting groove 32 of the electrical equipment 30, thereby completing the wiring installation of the shielded wire 20 and the electrical equipment 30. Since the clamping component 131 can move flexibly with the help of the actuating component 132, shielded wires 20 of different specifications and sizes can be flexibly and reliably clamped and fixed by the clamping component 131 when they are passed through the wiring carrier 11. This makes the same grounding device 10 capable of being used for the installation of shielded wires 20 of different specifications and sizes. This not only makes the wiring operation convenient, labor-saving and efficient, but also saves the need to equip a large number of different grounding devices 10, effectively reducing costs, and solving the problem of difficult storage and management of grounding devices 10.
[0045] Please continue reading. Figure 3 and Figure 4 In one embodiment, the clamping assembly 131 includes a rotating shaft 1311, a transmission block 1312, and a pressure plate 1313. The rotating shaft 1311 is disposed on the wiring carrier tube 11, the transmission block 1312 is rotatably disposed on the rotating shaft 1311, and the pressure plate 1313 is connected and fixed to the transmission block 1312. The pressure plate 1313 is used to clamp the shielding wire 20 passing through the cavity of the wiring carrier tube 11. The actuation assembly 132 is in transmission cooperation with the transmission block 1312.
[0046] When the shielded wire 20 is installed through the connector 11, the actuating component 132 moves away from the transmission block 1312, that is, it does not exert a pushing force on the transmission block 1312. After the shielded wire 20 is installed in place through the connector 11, the actuating component 132 moves on the connector 11. The actuating component 132 pushes the transmission block 1312 to rotate. The transmission block 1312 then drives the pressure plate 1313 to squeeze the shielded wire 20, thereby achieving the effect of pressing the shielded wire 20 and ensuring that the shielded wire 20 is installed firmly in the connector 11.
[0047] Please continue reading. Figure 3 and Figure 4Furthermore, the wiring carrier tube 11 has a receiving groove 111, in which the rotating shaft 1311 and the pressure plate 1313 are both installed, and at least a portion of the transmission block 1312 is located within the receiving groove 111. That is, the receiving groove 111 accommodates the rotating shaft 1311, the pressure plate 1313, and at least a portion of the transmission block 1312, making the wiring carrier tube 11 and the clamping assembly 131 structurally compact, thereby reducing the volume and space occupied by the grounding device 10 and facilitating installation and use. In addition, the sidewall of the receiving groove 111 contacts the transmission block 1312, which guides and limits the rotation of the transmission block 1312, improving the movement accuracy and stability of the transmission block 1312 and the pressure plate 1313, thereby ensuring that the pressure plate 1313 reliably and effectively clamps and fixes the shielding wire 20.
[0048] For example, the pressure plate 1313 is an arc plate with a certain curvature, and its curvature is adapted to the curvature of the shielding wire 20, so that the contact area between the pressure plate 1313 and the shielding wire 20 is larger, thereby improving the compression effect.
[0049] Furthermore, based on any of the above embodiments, the side of the transmission block 1312 away from the pressure plate 1313 is provided with a ramp surface, which is slidably engaged with the actuating component 132. The actuating component 132 slides linearly along the center line of the connector tube 11. When the actuating component 132 pushes the transmission block 1312 and slides relative to the ramp surface, it is easier to push the transmission block 1312 to rotate, thereby pushing the pressure plate 1313 to quickly press the shielding wire 20.
[0050] Please continue reading. Figure 3 and Figure 4 In one embodiment, the outer wall of the connector tube 11 is provided with a first external thread 112. The actuating component 132 includes a threaded sleeve 1321 and an operating ring 1322. The threaded sleeve 1321 is sleeved on the inner wall of the operating ring 1322, and the first internal thread of the threaded sleeve 1321 is screwed to the first external thread 112. By rotating the operating ring 1322, the operating ring 1322 drives the threaded sleeve 1321 to move on the connector tube 11, thereby realizing that the actuating component 132 squeezes and pushes the transmission block 1312. This threaded turning operation is simple, convenient and labor-saving, and makes it easier to tighten or loosen the shielding wire 20.
[0051] Furthermore, based on any of the above embodiments, at least two clamping components are provided, which are spaced apart along the circumferential direction on the wiring carrier pipe 11, and both clamping components are synchronously driven and engaged with the actuating component 132. Therefore, when the actuating component 132 slides along the grounding pipe, the actuating component 132 can simultaneously squeeze and drive at least two clamping components to rotate towards the center line of the grounding pipe, thereby simultaneously clamping the shielding wire 20, thereby improving the reliability and effectiveness of the installation and fixation of the shielding wire 20.
[0052] Please continue reading. Figure 2 , Figure 3 and Figure 5 In one embodiment, the connector mechanism 12 includes a connector sleeve 121 and a connecting ring 122. The connector sleeve 121 is fitted and fixed to the outside of the connecting ring 122. One end of the connecting ring 122 is connected to the wiring carrier pipe 11, and the other end of the connecting ring 122 is used to connect to the connecting pipe 31 of the electrical equipment 30. By operating the connector sleeve 121, the connecting ring 122 can be driven to connect and assemble with the connecting pipe 31, so as to realize the connection between the grounding device 10 and the electrical equipment 30, and simultaneously drive the shielding wire 20 to be inserted into the connecting groove 32 to complete the shielding wiring operation. That is, when the grounding device 10 of this solution is installed, the assembly of the grounding device 10 and the electrical equipment 30 and the wiring operation of the shielding wire 20 can be completed simultaneously, and the two parts of the operation are completed at the same time, which greatly improves the work efficiency.
[0053] More specifically, in one embodiment, the inner ring wall of the connecting ring 122 is provided with a second internal thread, which is used to screw into the second external thread 311 of the connecting pipe 31 of the electrical equipment 30. The threaded connection method can conveniently and quickly realize the assembly, fixing or disassembly of the grounding device 10 and the electrical equipment 30, with high assembly and disassembly efficiency, simple operation and strong feasibility.
[0054] Of course, in other alternative embodiments, snap-fit connection, adhesive connection, magnetic connection, etc. can be used to replace the screw connection method of the second internal thread and the second external thread 311. The specific choice can be made flexibly according to the actual needs, and will not be elaborated here.
[0055] Please continue reading. Figure 5 Furthermore, in another embodiment, the outer wall of the wiring carrier tube 11 is provided with an annular guide groove 113, and a slider 14 is slidably installed in the annular guide groove 113. The slider 14 is connected and fixed to the connecting ring 122. Since the slider 14 is fixed to the connecting ring 122, when the rotating connector sleeve 121 drives the connecting ring 122 to rotate, the connecting ring 122 will gradually move and be sleeved on the connecting tube 31 by means of the thread pair transmission action of the second internal thread and the second external thread 311. During this process, the slider 14 rotates and slides in the annular guide groove 113 under the drive of the connecting ring 122, and at the same time, it also exerts a pulling force on the wiring carrier tube 11, so as to drive the shielded wire 20 to automatically insert into the connecting groove 32 to complete the wiring operation.
[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
