Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and more specifically, to a fixing component. Background Technology

[0002] The primary purpose of measuring grounding grid resistance is to ensure the grounding performance of electrical equipment and systems, thereby protecting personal safety, preventing equipment damage, and ensuring the stable operation of the power system. Currently, measuring grounding grid resistance requires using a down conductor to connect to the earth and employing terminal blocks to measure the resistance.

[0003] However, due to the lack of an effective design mechanism to maintain the stability of the connection, once the fastening components become loose, the connection between the grounding terminal and the down conductor will become unstable. This not only affects the accuracy of the measurement results, but may also cause the grounding system to malfunction, thereby endangering the safety of equipment and personnel. Summary of the Invention

[0004] This invention provides a fixing component to solve the problem of unstable connection between the grounding terminal and the down conductor in related technologies.

[0005] This invention provides a fixing assembly for fixing terminals and downleads. The fixing assembly includes: a receiving rod having a receiving notch; a clamping assembly including a first clamping plate and a second clamping plate, both the first and second clamping plates being detachably mounted on the receiving rod and located at the receiving notch, the first clamping plate and the receiving rod together forming a first clamping groove for clamping a grounding terminal, the second clamping plate being located on the side of the first clamping plate away from the first clamping groove, the first and second clamping plates together forming a second clamping groove for clamping a downlead; and a limiting assembly located on the side of the second clamping plate away from the second clamping groove. The limiting component is disposed on the receiving rod and abuts against the second clamping plate to fix the second clamping plate on the receiving rod; the stop component includes a first rod body and a first stop member. The first rod body is movably disposed on the receiving rod, and the first stop member is movably disposed on the first rod body. The first stop member has an initial state and a stop state. The first rod body can switch the first stop member from the initial state to the stop state. When the first stop member is in the stop state, the first stop member is located between the second clamping plate and the limiting component and stops the second clamping plate, and the first rod body is limited to the receiving rod.

[0006] Furthermore, the stop assembly also includes a second rod and a second stop member movably disposed on the second rod. The first stop member and the second stop member are arranged at intervals in the circumferential direction of the receiving rod. The limiting assembly can drive the second rod to move so that the second stop member can move. When the stop member is in the stopped state, both the first stop member and the second stop member are located between the second clamping plate and the limiting assembly, and stop the second clamping plate.

[0007] Furthermore, the first stop includes a first protrusion, which is hinged to the first rod. The first rod allows the first protrusion to rotate. When the first stop is in the stop state, the first protrusion stops the second clamping plate. The second stop includes a second protrusion. There are multiple second protrusions and multiple first protrusions. The multiple first protrusions and multiple second protrusions are spaced apart and together form a ring structure. When the stop is in the stop state, the multiple first protrusions and multiple second protrusions all stop the second clamping plate.

[0008] Furthermore, the stop component also includes multiple stop rods, all of which are disposed on the second rod body. The multiple stop rods are disposed in a one-to-one correspondence with multiple second protrusions. The limiting component can drive the stop rods to move, so as to move the second rod body.

[0009] Furthermore, the stop member also includes a stop ring, which is connected to the first rod body. The stop ring is located on the side of the stop rod away from the first protrusion. When the stop member is in the stop state, the stop ring stops the stop rod.

[0010] Further, the first rod body includes a first connecting plate, a plurality of first hinge rods, and a plurality of connecting rods. The plurality of connecting rods are spaced apart circumferentially along the first connecting plate. The first ends of the plurality of first hinge rods are hinged to the plurality of connecting rods in a corresponding manner. The plurality of first protrusions are hinged to the second ends of the plurality of first hinge rods in a corresponding manner. A stop ring is connected to the outer periphery of the plurality of connecting rods. The second rod body includes a second connecting plate and a plurality of second hinge rods. The second connecting plate is located inside the plurality of connecting rods. The first ends of the plurality of second hinge rods are hinged together circumferentially along the second connecting plate. The protrusions are hinged to the second ends of the plurality of second hinge rods in a one-to-one correspondence, and the plurality of stop rods are spaced apart circumferentially along the second connecting plate; the stop assembly also includes a guide post, the guide post having a plurality of guide grooves extending along its axial direction, the first end of the guide post being connected to a receiving rod, the first connecting plate being located outside the second end of the guide post, the second connecting plate being located inside the guide post, the plurality of connecting rods being located inside the guide post, the plurality of first hinge rods and the plurality of second hinge rods passing through the plurality of guide grooves in a one-to-one correspondence, the plurality of stop rods passing through a portion of the guide grooves in a one-to-one correspondence, and the stop ring being located on the outer periphery of the guide post.

[0011] Furthermore, the receiving rod has a receiving cavity and multiple strip grooves, which are spaced apart circumferentially along the receiving rod and communicate with the receiving cavity. The strip grooves extend along the length of the receiving rod. The limiting assembly includes a limiting ring, which is sleeved on the receiving rod. The inner ring of the limiting ring has a first spring post that is movable in the radial direction of the receiving rod. The first spring post can abut against the stop rod to move the second rod.

[0012] Furthermore, the stop assembly also includes a drive column, which comprises a column body and multiple spring pieces. The multiple spring pieces are spaced apart circumferentially along the column body. The receiving rod has a receiving cavity, and the column body is located within the receiving cavity and connected to the end of the first rod body away from the first protrusion. The column body can drive the first rod body to move. The first ends of the multiple spring pieces are all connected to the column body. The cavity wall of the receiving cavity is provided with multiple limiting grooves, and the second ends of the multiple spring pieces can be inserted into the multiple limiting grooves one by one to make the first rod body and the receiving rod limit each other. The cavity wall of the receiving cavity is provided with multiple limiting shells, and the multiple limiting grooves are provided in the multiple limiting shells one by one. Each limiting shell contains a movable button, and a first spring is fitted on the button. The two ends of the first spring abut against the button and the limiting shell, respectively. The first end of the button protrudes through the outer wall of the receiving rod, and the second end of the button extends into the limiting groove and abuts against the second end of the spring piece. The button can drive the second end of the spring piece to separate from the limiting groove. The driving column also includes a second spring fitted on the column body. The outer periphery of the column body is provided with an annular protrusion. The two ends of the second spring abut against the receiving rod and the annular protrusion, respectively. After the spring piece separates from the limiting groove, the second spring can drive the column body to move away from the first rod body.

[0013] Furthermore, the limiting assembly includes a limiting ring, which is sleeved on the receiving rod. The inner ring of the limiting ring has a plurality of second spring posts that are movable in the radial direction of the receiving rod. The plurality of second spring posts can be pressed onto a plurality of buttons in a corresponding manner to move the buttons and drive the second end of the spring to separate from the limiting groove.

[0014] Furthermore, the limiting assembly includes a limiting ring, which includes a washer and a fastening ring. The washer is sandwiched between the second clamping plate and the fastening ring, and the fastening ring is threadedly connected to the receiving rod. The receiving rod is a U-shaped rod, with the first clamping plate and the second clamping plate both passing through the two straight sections of the U-shaped rod. The arc-shaped section of the U-shaped rod forms a receiving notch. The first clamping plate is located between the second clamping plate and the arc-shaped section of the U-shaped rod, and the first clamping plate and the arc-shaped section of the U-shaped rod together form a first clamping groove.

[0015] According to the technical solution of this invention, the fixing assembly includes a receiving rod, a clamping assembly, a limiting assembly, and a stop assembly. Since the first clamping plate and the second clamping plate are detachably mounted on the receiving rod and located at the receiving notch, the first clamping plate can seal the receiving notch and, together with the receiving rod, form a first clamping groove for clamping the grounding terminal. The grounding terminal is placed in the first clamping groove, and the down conductor is placed in the second clamping groove formed by the first and second clamping plates. Then, the limiting assembly is installed on the receiving rod. By moving the first rod body relative to the receiving rod, the first rod body can move the first stop member from its initial state to a stopped state. At this time, the first rod body can be limited and relatively stationary with the receiving rod. The first stop member is located between the second clamping plate and the limiting assembly and can stop the second clamping plate, so that the second clamping plate and the first clamping plate are stably fixed on the receiving rod. Then, by using the limiting assembly to abut against the second clamping plate, the first and second clamping plates can be fixed again, preventing the first and second clamping plates from loosening on the receiving rod. Furthermore, even if the limiting component becomes loose on the receiving rod, the first stop can still act as a stop, preventing the first and second clamping plates from becoming loose relative to the receiving rod. This protects the safety of the equipment and personnel. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1 to 16 As shown, this embodiment of the invention provides a fixing assembly for fixing terminals and downleads. The fixing assembly includes a receiving rod 10, a clamping assembly, a limiting assembly, and a stop assembly. The receiving rod 10 has a receiving notch. The clamping assembly includes a first clamping plate 11 and a second clamping plate 12, both of which are detachably mounted on the receiving rod 10 and located at the receiving notch. The first clamping plate 11 and the receiving rod 10 together form a first clamping groove for clamping the grounding terminal. The second clamping plate 12 is located on the side of the first clamping plate 11 away from the first clamping groove. The first clamping plate 11 and the second clamping plate 12 together form a second clamping groove for clamping the downlead. The limiting assembly is located at... On the side of the second clamping plate 12 away from the second clamping groove, a limiting component is disposed on the receiving rod 10 and abuts against the second clamping plate 12 to fix the second clamping plate 12 on the receiving rod 10; the stop component includes a first rod body and a first stop member. The first rod body is movably disposed on the receiving rod 10, and the first stop member is movably disposed on the first rod body. The first stop member has an initial state and a stop state. The first rod body can switch the first stop member from the initial state to the stop state. When the first stop member is in the stop state, the first stop member is located between the second clamping plate 12 and the limiting component and stops the second clamping plate 12, and the first rod body is limited to the receiving rod 10.

[0043] According to the technical solution of this invention, the fixing assembly includes a receiving rod 10, a clamping assembly, a limiting assembly, and a stop assembly. Since the first clamping plate 11 and the second clamping plate 12 are detachably mounted on the receiving rod 10 and located at the receiving notch, the first clamping plate 11 can seal the receiving notch and, together with the receiving rod 10, form a first clamping groove for clamping the grounding terminal. The grounding terminal is placed in the first clamping groove, and the down conductor is placed in the second clamping groove formed by the first clamping plate 11 and the second clamping plate 12. Then, the limiting assembly is installed on the receiving rod 10. By moving the first rod body relative to the receiving rod 10, the first rod body can move the first stop member from its initial state to a stopped state. At this time, the first rod body can be limited and relatively stationary with the receiving rod 10. The first stop member is located between the second clamping plate 12 and the limiting assembly and can stop the second clamping plate 12, so that the second clamping plate 12 and the first clamping plate 11 are stably fixed on the receiving rod 10. The limiting component then abuts against the second clamping plate 12, thus securing the first clamping plate 11 and the second clamping plate 12 again and preventing them from loosening on the receiving rod 10. Furthermore, even if the limiting component becomes loose on the receiving rod 10, the first stop member will provide a stop, ensuring that the first clamping plate 11 and the second clamping plate 12 do not loosen relative to the receiving rod 10. This protects the safety of the equipment and personnel.

[0044] Specifically, when the first stop is in its initial state, it is positioned close to the first rod. When the first stop is in its stopped state, it abuts against the receiving rod 10 due to the movement of the first rod. Furthermore, due to the continued movement of the first rod, the first stop can move relative to the first rod, thereby stopping the second clamping plate.

[0045] In this embodiment, both the first clamping plate 11 and the second clamping plate 12 are strip plates. The opposite sides of the first clamping plate 11 and the second clamping plate 12 each have a groove. The two grooves are joined together to form a second receiving groove to hold the lead wire.

[0046] like Figure 13 and Figure 14 As shown, the stop assembly also includes a second rod and a second stop member movably disposed on the second rod. The first and second stop members are spaced apart in the circumferential direction of the receiving rod 10. The limiting assembly can drive the second rod to move, thereby moving the second stop member. When the stop member is in the stopped state, both the first and second stop members are located between the second clamping plate 12 and the limiting assembly, and stop the second clamping plate 12. The second stop member can stop the second clamping plate 12, thereby cooperating with the first stop member to enhance the stopping effect. Even if the limiting assembly becomes loose on the receiving rod 10, the first clamping plate 11 and the second clamping plate 12 will not become loose relative to the receiving rod 10.

[0047] In this embodiment, during the installation of the limiting component, the second rod can be driven to move. Initially, the second stop is set close to the second rod. When the second stop stops, it abuts against the receiving rod 10 due to the movement of the second rod. As the second rod continues to move, the second stop can move relative to the second rod, thereby stopping the second clamping plate.

[0048] In other embodiments, both the first stop and the second stop can be disposed on the first rod, thus eliminating the need to use a limiting component to drive the second rod to move and then drive the second stop to move through the second rod, and also eliminating the need to provide the second rod.

[0049] like Figure 14 As shown, the first stop includes a first protrusion 74, which is hinged to the first rod. The first rod allows the first protrusion 74 to rotate. When the first stop is in the stopped state, the first protrusion 74 stops the second clamping plate 12. Using the aforementioned first stop, by moving the first rod, the first protrusion 74 can be moved, causing it to abut against the receiving rod 10. With continued movement of the first rod, the first protrusion 74 can rotate relative to the first rod, thereby stopping the second clamping plate 12.

[0050] In this embodiment, the first protrusion 74 has a triangular cross-section, the second clamping plate 12 is sleeved on the receiving rod 10, and the limiting component is also sleeved on the receiving rod 10. The inner sidewalls of the second clamping plate 12 and the limiting component have a chamfered structure. When the first stop is in the stop state, the upper end of the first protrusion 74 can be inserted into the chamfered structure to form a stop function.

[0051] like Figure 10 and Figure 16 As shown, the second stop includes a second protrusion 63. There are multiple second protrusions 63 and multiple first protrusions 74. These multiple first protrusions 74 and multiple second protrusions 63 are spaced apart and together form a ring structure. When the stop is in the stopping state, both the multiple first protrusions 74 and multiple second protrusions 63 stop the second clamping plate 12. Using the above-described second stop, by moving the second rod, the second protrusion 63 can be moved, causing it to abut against the receiving rod 10. With the continued movement of the second rod, the second protrusion 63 can rotate relative to the second rod, thereby stopping the second clamping plate 12.

[0052] In this embodiment, the first rod and the second rod are movable along the axial direction of the receiving rod 10.

[0053] It should be noted that, since both the first rod and the second rod can move relative to the accommodating rod 10, and the multiple first protrusions 74 and the multiple second protrusions 63 form a ring structure, they need to avoid each other during the movement to form a staggered movement and avoid mutual interference during the movement.

[0054] like Figure 10 and Figure 13 As shown, the stop component also includes multiple stop rods 611, all of which are disposed on the second rod body. Each stop rod 611 corresponds one-to-one with a multiple second protrusion 63. The limiting component can drive the stop rods 611 to move, thereby causing the second rod body to move. Using the limiting component to drive the stop rods 611 to move, and thus the second rod body to move, has the advantages of simple structure and ease of operation.

[0055] In this embodiment, the stop bar 611 extends in the radial direction of the receiving bar 10.

[0056] like Figure 10 and Figure 14 As shown, the stop component also includes a stop ring 71, which is connected to the first rod body. The stop ring 71 is located on the side of the stop rod 611 away from the first protrusion 74. When the stop component is in the stop state, the stop ring 71 stops the stop rod 611. The stopping effect formed by the stop ring 71 and the stop rod 611 can further enhance the stopping effect of the stop assembly on the second clamping plate.

[0057] It should be noted that in order for the stop ring 71 to act as a stop on the stop rod 611, the stop rod 611 should move before the stop ring 71, and the first protrusion 74 should act as a stop before the second protrusion 63.

[0058] like Figure 15 As shown, the first rod includes a first connecting plate 75, a plurality of first hinge rods 73, and a plurality of connecting rods 72. The plurality of connecting rods 72 are spaced apart circumferentially along the first connecting plate 75. The first ends of the plurality of first hinge rods 73 are hinged to the plurality of connecting rods 72 in a one-to-one correspondence, and the plurality of first protrusions 74 are hinged to the second ends of the plurality of first hinge rods 73 in a one-to-one correspondence. A stop ring 71 is connected to the outer periphery of the plurality of connecting rods 72. The first rod with the above structure can support the plurality of first hinge rods 73 and the first protrusions 74 through the first connecting plate 75 and the plurality of connecting rods 72, and has the advantages of simple structure and easy processing.

[0059] In this embodiment, the first connecting plate 75 extends along the axial direction of the receiving rod 10. When the stop member is in the stop state, the extension direction of the first hinge rod 73 is perpendicular to the extension direction of the first connecting plate 75.

[0060] like Figure 13As shown, the second rod includes a second connecting plate 61 and a plurality of second hinge rods 62. The second connecting plate 61 is located inside the plurality of connecting rods 62. The first ends of the plurality of second hinge rods 62 are hinged at intervals along the circumference of the second connecting plate 61. A plurality of second protrusions 63 are correspondingly hinged to the second ends of the plurality of second hinge rods 62. A plurality of stop rods 611 are spaced at intervals along the circumference of the second connecting plate 61. The second rod with the above structure can support the second hinge rods 62 using the second connecting plate 61, and has the advantages of simple structure and easy processing.

[0061] The second connecting plate 61 is located inside the plurality of connecting rods 72, meaning that the plurality of connecting rods 72 surround the outer periphery of the second connecting plate 61, thereby enabling the second connecting plate 61 to be avoided. When the first rod moves or the second rod moves, the connecting rods 72 and the second connecting plate 61 will not interfere with each other.

[0062] In this embodiment, the second connecting plate 61 is a cross-shaped plate structure.

[0063] like Figure 13 As shown, the stop assembly also includes a guide post 41, which has multiple guide grooves 42 extending along its axial direction. The first end of the guide post 41 is connected to the receiving rod 10. A first connecting plate 75 is located outside the second end of the guide post 41. A second connecting plate 61 is located inside the guide post 41 and inserted into a corresponding portion of the guide groove 42. Multiple connecting rods 72 are inserted into the remaining portions of the guide grooves 42. Multiple first hinge rods 73 and multiple second hinge rods 62 pass through the multiple guide grooves 42 in a corresponding manner. Multiple stop rods 611 protrude from a portion of the guide grooves 42 in a corresponding manner. A stop ring 71 is located on the outer periphery of the guide post 41. Using the guide post 41 described above, the guide grooves 42 can provide guidance, allowing the second connecting plate 61 and connecting rods 72 to move along the extension direction of the guide grooves 42. This enables the first protrusion 74 and the second protrusion 63 to form a stable annular stop structure, preventing the stop from failing to form due to skewness.

[0064] In this embodiment, there are eight guide grooves 42, which are arranged at intervals along the circumference. Since the second connecting plate 61 has a cross-shaped structure, it can be inserted into four guide grooves 42. There are four first connecting plates 75, which are inserted into the other four guide grooves 42.

[0065] like Figure 13As shown, the receiving rod 10 has a receiving cavity and multiple strip grooves 14. The multiple strip grooves 14 are spaced apart circumferentially along the receiving rod 10 and communicate with the receiving cavity. The strip grooves 14 extend along the length direction of the receiving rod 10. The limiting assembly includes a limiting ring, which is sleeved on the receiving rod 10. The inner ring of the limiting ring has a first spring post 23 that is movable in the radial direction of the receiving rod 10. The first spring post 23 can abut against the stop rod 611 to move the second rod. With the above structure, the stop rod 611 can pass through the strip grooves 14 and then be driven by the first spring post 23 to move along the extension direction of the strip grooves 14.

[0066] In this embodiment, the first rod, the second rod, and the guide post 41 are all disposed within the receiving cavity. The receiving rod 10 has multiple clearance grooves communicating with the receiving cavity. When the stop member is in the stop state, multiple first protrusions 74 and multiple second protrusions 63 can pass through the corresponding clearance grooves to exit the receiving rod 10 to stop the second clamping plate 12.

[0067] There are multiple first spring posts 23, and each of the multiple first spring posts 23 is set in a one-to-one correspondence with a multiple stop bar 611.

[0068] Specifically, the first spring post 23 includes a first moving rod 231 movable in the radial direction along the receiving rod 10. A first moving block 232 is provided at the end of the first moving rod 231, and a third spring 233 is provided on the outer ring of the first moving rod 231. The third spring 233 can provide a driving force to the first moving rod 231, so that the first moving block 232 is exposed outside the inner ring of the limiting ring.

[0069] In this embodiment, the groove 14 is provided with an inclined surface, which facilitates the entry of the first spring post 23 into the groove 14.

[0070] like Figure 9 , Figure 11 as well as Figure 12As shown, the stop assembly also includes a drive column 50, which includes a column body 51 and multiple spring pieces 57. The multiple spring pieces 57 are spaced apart circumferentially along the column body 51. The column body 51 is located inside the receiving cavity and connected to the end of the first rod away from the first protrusion 74. The column body 51 can drive the first rod to move. The first ends of the multiple spring pieces 57 are all connected to the column body 51. The cavity wall of the receiving cavity is provided with multiple limiting grooves. The second ends of the multiple spring pieces 57 can be inserted into the multiple limiting grooves one by one to limit the engagement of the first rod and the receiving rod 10. Using the above-described drive column 50, the column body 51 can drive the first rod to move, thereby causing the multiple first protrusions 74 to stop the second clamping plate 12. Furthermore, the spring pieces 57 on the column body 51 can limit the column body 51, preventing it from moving away from the first rod, thus preventing the first rod from moving and allowing the multiple first protrusions 74 to stably stop the second clamping plate 12.

[0071] In this embodiment, the column 51 is inserted into the receiving cavity, and the column 51 can move along the axial direction of the receiving rod 10. One end of the column 51 is located outside the receiving rod 10, which facilitates the operator to perform pressing operations.

[0072] like Figure 12 As shown, the cavity wall of the receiving cavity is provided with multiple limiting shells 55, and multiple limiting grooves are correspondingly provided on the multiple limiting shells 55. Each limiting shell 55 is provided with a movable button 54. A first spring 56 is sleeved on the button 54. The two ends of the first spring 56 abut against the button 54 and the limiting shell 55, respectively. The first end of the button 54 protrudes through the outer wall of the receiving rod 10, and the second end of the button 54 extends into the limiting groove and abuts against the second end of the spring piece 57. The button 54 can drive the second end of the spring piece 57 to separate from the limiting groove. With the above structure, by pressing the button 54, the button 54 can abut against the second end of the spring piece 57, causing the spring piece 57 to disengage from the limiting groove, thereby releasing the limiting effect of the receiving rod 10 on the column 51, allowing the column 51 to move, so as to release the stopping effect of the first protrusion 74 on the second clamping plate 12.

[0073] In this embodiment, the first spring 56 provides a restoring force, causing the button 54 to automatically reset after being released.

[0074] The receiving rod 10 is provided with a protective plate 13 on its outside. The protective plate 13 is located outside the button 54. The protective plate 13 can prevent the button 54 from being pressed due to other accidental factors, thereby preventing the stop of the first protrusion 74 from failing.

[0075] like Figure 11As shown, the drive column 50 also includes a second spring 53 sleeved on the column body 51. An annular protrusion 52 is provided on the outer periphery of the column body 51. The two ends of the second spring 53 abut against the receiving rod 10 and the annular protrusion 52, respectively. After the spring piece 57 separates from the limiting groove, the second spring 53 can drive the column body 51 to move away from the first rod. The second spring 53 provides a restoring force; after the second end of the spring piece 57 disengages from the limiting groove, this restoring force allows the column body 51 to move away from the first rod, thereby releasing the blocking effect of the first protrusion 74 on the second clamping plate 12.

[0076] like Figure 7 As shown, the limiting assembly includes a limiting ring sleeved on the receiving rod 10. The inner ring of the limiting ring has multiple second spring posts 24 movable in the radial direction of the receiving rod 10. The multiple second spring posts 24 can be pressed one-to-one onto multiple buttons 54 to move the buttons 54 and drive the second end of the spring piece 57 to separate from the limiting groove. With the above structure, after the column 51 moves away from the first rod and releases the stop of the first protrusion 74 on the second clamping plate, when the limiting ring is removed, the second spring posts 24 can be used to press the buttons 54, thereby causing the buttons 54 to abut against the spring piece 57, releasing the spring piece 57 from limiting the column 51, and thus allowing the column 51 to move.

[0077] Specifically, the second spring post 24 includes a second moving rod 241 movable in the radial direction along the receiving rod 10. A second moving block 242 is provided at the end of the second moving rod 241, and a fourth spring 243 is provided on the outer ring of the second moving rod 241. The fourth spring 243 can provide a driving force for the second moving rod 241, so that the second moving block 242 is exposed outside the inner ring of the limiting ring.

[0078] In this embodiment, the size of the second moving block 242 is smaller than the size of the first moving block 232.

[0079] like Figure 1 As shown, the limiting assembly includes a limiting ring, which includes a washer 20 and a fastening ring 30. The washer 20 is sandwiched between the second clamping plate 12 and the fastening ring 30, and the fastening ring 30 is threadedly connected to the receiving rod 10. The limiting assembly described above has the advantages of simple structure and easy assembly / disassembly.

[0080] The first spring post 23 and the second spring post 24 are both mounted on the washer 20. The side wall of the washer 20 has a first notch 21 and a second notch 22. The first notch 21 corresponds to the first spring post 23, and the second notch 22 corresponds to the second spring post 24. During installation, rotating the washer to the first notch 21 allows the first spring post 23 to drive the stop rod 611 to move. During disassembly, rotating the washer to the second notch 22 allows the second spring post 24 to press the button 54.

[0081] like Figure 1 As shown, the receiving rod 10 is a U-shaped rod. The first clamping plate 11 and the second clamping plate 12 are both inserted through the two straight sections of the U-shaped rod. The arc-shaped section of the U-shaped rod forms a receiving notch. The first clamping plate 11 is located between the second clamping plate 12 and the arc-shaped section of the U-shaped rod. The first clamping plate 11 and the arc-shaped section of the U-shaped rod together form the first clamping groove. Using a U-shaped rod to receive the terminal block has the advantages of simple structure and ease of operation.

[0082] In this embodiment, the receiving cavity of the receiving rod 10 is provided on its straight rod section.

[0083] The following section explains the specific usage process of the fixed components:

[0084] During installation, the operator needs to place the receiving rod 10 in the correct position of the grounding terminal, ensuring that the opening of the receiving rod 10 is aligned with the grounding terminal for subsequent device installation. Then, the first clamp 11 passes through the two straight rod sections of the receiving rod 10 and makes direct physical contact with the grounding terminal, ensuring a good electrical connection.

[0085] Next, the operator leads the down conductor into the contact area of ​​the first clamp 11 and establishes a connection through physical contact. At this time, the second clamp 12 is inserted and clamps and fixes the down conductor.

[0086] Subsequently, the washer 20 is inserted into the receiving rod 10. It should be noted that when the washer 20 approaches the second clamping plate 12, the operator needs to rotate the washer 20 so that the first notch 21 on it faces the extension direction of the grounding terminal. This rotation causes the first moving block 232 inside the washer 20 to push the stop rod 611, thereby driving the second protrusion 63 to protrude outward and cooperate with the stop of the second clamping plate 12 to achieve a firm clamping of the grounding terminal and the lead wire.

[0087] Next, the operator must thread the retaining ring 30 onto the end of the receiving rod 10 to ensure the stability of the entire device and continuous contact between the grounding terminal and the lead wire.

[0088] To further enhance the clamping effect, the operator needs to press the column 51. The column 51 drives the connecting rod 72 to move through the first connecting plate 75, thereby making the first protrusion 74 relatively movable. The second protrusion 63 and the first protrusion 74 together form an annular protrusion structure, and the stop ring 71 stops outside the stop rod 611. Even if the fastening ring 30 and the washer 20 may become loose, the stable clamping of the grounding terminal and the lead wire can be maintained.

[0089] During the release of the clamp, the fastening ring 30 needs to be removed first. Then, the operator needs to remove the washer 20. When the washer 20 moves to the position of the protective plate 13, the operator needs to rotate the washer 20 to align the second notch 22 with the extension direction of the grounding terminal, so that the second moving block 242 presses against the button 54, causing the spring piece 57 to disengage from the limiting shell 55, thereby removing the restriction on the column 51. In this way, the column 51 returns to its initial position under the restoring force of the second spring 53, releasing the restriction on the second protrusion 63 and the first protrusion 74, allowing the second protrusion 63 and the first protrusion 74 to reset freely.

[0090] Subsequently, the operator can smoothly remove the first clamping plate 11 and the second clamping plate 12. The first clamping plate 11 slides out from the receiving rod 10, disconnecting from the grounding terminal. The second clamping plate 12 is also removed, releasing the fixation of the down conductor. During this process, the second protrusion 63 is also automatically retracted into the inner cavity of the receiving rod 10 as the two clamping blocks move, completing the entire disassembly process.

[0091] In this way, the entire operation process not only ensures accurate measurement of grounding resistance, but also ensures the rapid and safe assembly and disassembly of the equipment.

[0092] The application of the fixing component provided in this embodiment has the following beneficial effects:

[0093] 1. By combining the U-shaped rod with the first clamping plate 11 and the second clamping plate 12 on it, the grounding terminal and the down conductor can be clamped and fixed at the same time. This design significantly improves the operating efficiency of the wiring kit.

[0094] 2. The internal cylindrical structure of the device has a first protrusion 74 and a second protrusion 63. These protrusions form an annular protrusion, which can maintain stable clamping of the grounding terminal and the lead wire even if the fastening ring and the washer are loose. This design greatly improves the reliability and anti-interference ability of the device and ensures stable performance in various working environments.

[0095] 3. The washer can be installed on the U-shaped rod at a specific angle, thereby driving the second protrusion 63 to unfold, and the column 51 to drive the first protrusion 74 to open. This design makes the installation process of the device simpler and faster, reduces the operation time and difficulty, and improves the user experience.

[0096] 4. When the column 51 forms the annular protrusion, it can maintain the position of the second protrusion 63, while the spring 57 transmits the fixing force of the column 51 to the first protrusion 74. Even if the washer loosens and loses its limiting effect on the first protrusion 74, the annular protrusion can still maintain the stable fixation of the grounding terminal and the lead wire through the annular baffle and the column 51.

[0097] 5. The first notch 21 and the second notch 22 on the washer provide precise reference points to ensure that the washer can be correctly installed or removed at a specific angle. If the washer cannot be removed from the U-shaped rod at a specific angle, the second protrusion 63 will not be able to reset. This design effectively prevents the washer from falling off due to vibration or other accidental factors, thus releasing the clamping of the column 51 and ensuring the long-term stable use of the device.
