Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 16 As shown, an embodiment of the present invention provides a fixing assembly for fixing a wiring terminal and a down conductor, the fixing assembly comprises an accommodating rod 10, a clamping assembly, a limiting assembly, and a stop assembly, the accommodating rod 10 having an accommodating notch; the clamping assembly comprises a first clamping plate 11 and a second clamping plate 12, the first clamping plate 11 and the second clamping plate 12 are both detachably arranged on the accommodating rod 10 and located at the accommodating notch, the first clamping plate 11 and the accommodating rod 10 together form a first clamping groove for clamping a grounding terminal, the second clamping plate 12 is located on a 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 a down conductor; the limiting assembly is located at On the side of the second clamping plate 12 away from the second clamping groove, the limiting assembly is arranged on the accommodating rod 10 and abuts against the second clamping plate 12 to fix the second clamping plate 12 on the accommodating rod 10; the stopping assembly includes a first rod body and a first stop member, the first rod body is movably arranged on the accommodating rod 10, the first stop member is movably arranged 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 assembly and stops the second clamping plate 12, and the first rod body cooperates with the accommodating rod 10 in a limiting manner.

[0043] According to the technical solution of the present invention, the fixing assembly includes a receiving rod 10, a clamping assembly, a limiting assembly and a stopping assembly. Since the first clamping plate 11 and the second clamping plate 12 are detachably arranged on the receiving rod 10 and located at the receiving notch, the first clamping plate 11 can be used to block 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, and 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 stopping member from the initial state to the stopping state. At this time, the first rod body can cooperate with the receiving rod 10 in a limiting manner and remain relatively still. The first stopping 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 assembly is then used to abut against the second clamping plate 12, so that the first clamping plate 11 and the second clamping plate 12 can be fixed again to prevent the first clamping plate 11 and the second clamping plate 12 from being loosened on the receiving rod 10. Moreover, even if the limiting assembly is loosened on the receiving rod 10, the first stopper can also form a stopper effect, so that the first clamping plate 11 and the second clamping plate 12 will not be loosened relative to the receiving rod 10, thereby protecting the safety of the equipment and the staff.

[0044] Among them, when the first stop member is in the initial state, the first stop member is arranged close to the first rod body. When the first stop member is in the stopping state, the first stop member is abutted against the accommodating rod 10 due to the movement of the first rod body, and due to the continued movement of the first rod body, the first stop member can move relative to the first rod body, thereby stopping the second splint.

[0045] In this embodiment, the first clamping plate 11 and the second clamping plate 12 are both strip-shaped plates, and opposite sides of the first clamping plate 11 and the second clamping plate 12 have grooves, and the two grooves are spliced ​​to form a second accommodating groove to clamp the down conductor.

[0046] like Fig.13 and Fig.14 As shown, the stopper assembly also includes a second rod body and a second stopper movably disposed on the second rod body, the first stopper and the second stopper are arranged at intervals in the circumferential direction of the accommodation rod 10, the limiting assembly can drive the second rod body to move so as to move the second stopper, and when the stopper is in a stopping state, the first stopper and the second stopper are both located between the second clamping plate 12 and the limiting assembly, and stop the second clamping plate 12. The second stopper can form a stopping effect on the second clamping plate 12, and then cooperate with the first stopper to enhance the stopping effect, even if the limiting assembly is loose on the accommodation rod 10, the first clamping plate 11 and the second clamping plate 12 will not be loose relative to the accommodation rod 10.

[0047] In this embodiment, during the installation of the limit assembly, the second rod body can be driven to move, and the second stop member is initially arranged close to the second rod body. When the second stop member stops, the second stop member is abutted against the accommodating rod 10 due to the movement of the second rod body, and due to the continued movement of the second rod body, the second stop member can be moved relative to the second rod body, thereby stopping the second splint.

[0048] In other embodiments, the first stopper and the second stopper may be both disposed on the first rod, thereby eliminating the need to use a limiting assembly to drive the second rod to move, and then drive the second stopper to move through the second rod, and eliminating the need to dispose a second rod.

[0049] like Fig.14 As shown, the first stopper includes a first protrusion 74, which is hingedly arranged on the first rod body. The first rod body can make the first protrusion 74 rotate. When the first stopper is in a stopping state, the first protrusion 74 stops the second clamping plate 12. With the above-mentioned first stopper, by moving the first rod body, the first protrusion 74 can be driven to move, and then the first protrusion 74 is abutted against the receiving rod 10. By continuing to move the first rod body, the first protrusion 74 can rotate relative to the first rod body, and then stop the second clamping plate 12.

[0050] In this embodiment, the cross-section of the first protrusion 74 is a triangular structure, the second clamping plate 12 is sleeved on the accommodating rod 10, and the limiting assembly is also sleeved on the accommodating rod 10. The inner side walls of the second clamping plate 12 and the limiting assembly have a chamfered structure. When the first stop member is in a stopping state, the upper end of the first protrusion 74 can be inserted into the chamfered structure to form a stopping effect.

[0051] like Fig.10 and Fig.16 As shown, the second stopper includes a second protrusion 63, and the second protrusion 63 and the first protrusion 74 are both multiple. The multiple first protrusions 74 and the multiple second protrusions 63 are arranged one by one and together form an annular structure. When the stopper is in the stopping state, the multiple first protrusions 74 and the multiple second protrusions 63 both stop the second clamping plate 12. With the above-mentioned second stopper, by moving the second rod body, the second protrusion 63 can be driven to move, and then the second protrusion 63 is abutted against the accommodating rod 10. By continuing to move the second rod body, the second protrusion 63 can rotate relative to the second rod body, and then stop the second clamping plate 12.

[0052] In this embodiment, the first rod body and the second rod body can move along the axial direction of the accommodating rod 10 .

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

[0054] like Fig.10 and Fig.13 As shown, the stopper also includes a plurality of stopper rods 611, which are all arranged on the second rod body, and the plurality of stopper rods 611 are arranged one by one corresponding to the plurality of second protrusions 63, and the limit assembly can drive the stopper rods 611 to move so as to move the second rod body. The use of the limit assembly to drive the stopper rods 611 to move, thereby driving the second rod body to move, has the advantages of simple structure and easy operation.

[0055] In the present embodiment, the stopping rod 611 extends along the radial direction of the receiving rod 10 .

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

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

[0058] like Fig.15 As shown, the first rod body includes a first connecting plate 75, a plurality of first hinged rods 73 and a plurality of connecting rods 72, the plurality of connecting rods 72 are arranged at intervals along the circumference of the first connecting plate 75, the first ends of the plurality of first hinged rods 73 are hinged to the plurality of connecting rods 72 one by one, the plurality of first protrusions 74 are hinged to the second ends of the plurality of first hinged rods 73 one by one, and the stop ring 71 is connected to the outer circumference of the plurality of connecting rods 72. The first rod body adopting the above structure can support the plurality of first hinged rods 73 through the first connecting plate 75 and the plurality of connecting rods 72, so as to support the first protrusions 74, and has the advantages of simple structure and easy processing.

The second rod body with the above structure can support the second hinged rods 62 by using the second connecting plate 61, and has the advantages of simple structure and easy processing.

[0061] Among them, the second connecting plate 61 is located on the inner side of multiple connecting rods 72, which means that multiple connecting rods 72 are arranged around the outer periphery of the second connecting plate 61, so as to avoid the second connecting plate 61. When the first rod body moves, or when the second rod body 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 plate structure.

By adopting the above-mentioned guide column 41, the guide groove 42 can be used to form a guiding effect, so that the second connecting plate 61 and the connecting rod 72 move along the extension direction of the guide groove 42, so that the first protrusion 74 and the second protrusion 63 can form a stable annular stopper structure, and the stopper will not be unable to form a stopper due to deflection.

[0064] In this embodiment, there are eight guide grooves 42, which are arranged at intervals along the circumferential direction. Since the second connecting plate 61 is a cross plate structure, the second connecting plate 61 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.

The two ends of the first spring 56 are respectively in contact with the button 54 and the limiting shell 55. The first end of the button 54 passes through the outer wall of the accommodating rod 10, and the second end of the button 54 extends into the limiting groove and is in contact with the second end of the spring sheet 57. The button 54 can drive the second end of the spring sheet 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 sheet 57, so that the spring sheet 57 is disengaged from the limiting groove, thereby releasing the limiting of the accommodating rod 10 on the column 51, so that the column 51 can 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 can provide a restoring force, so that the button 54 is automatically reset after the button 54 is released.

[0074] A protective plate 13 is disposed outside the accommodating rod 10 and is located outside the button 54. The protective plate 13 can prevent the button 54 from being pressed due to other unexpected factors, thereby preventing the stopper of the first protrusion 74 from failing.

[0075] like Fig.11As shown, the driving column 50 also includes a second spring 53 sleeved on the column 51, and an annular protrusion 52 is provided on the outer periphery of the column 51. The two ends of the second spring 53 are respectively in contact with the accommodating rod 10 and the annular protrusion 52. After the spring piece 57 is separated from the limiting groove, the second spring 53 can drive the column 51 to move in a direction away from the first rod. The second spring 53 can provide a restoring force. After the second end of the spring piece 57 is separated from the limiting groove, the restoring force can be used to move the column 51 in a direction away from the first rod, so as to release the stopping 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, which is sleeved on the receiving rod 10, and the inner ring of the limiting ring has a plurality of second spring columns 24 that are movable along the radial direction of the receiving rod 10, and the plurality of second spring columns 24 can be pressed on the plurality of buttons 54 in a one-to-one correspondence, so that the buttons 54 move and drive the second end of the spring sheet 57 to separate from the limiting groove. With the above structure, after the column 51 moves in a direction away from the first rod body and the first protrusion 74 stops the second clamping plate, when the limiting ring is removed, the second spring column 24 can be used to press the button 54, so that the button 54 abuts against the spring sheet 57, so that the spring sheet 57 releases the limit on the column 51, and the column 51 can move.

[0077] Specifically, the second spring column 24 includes a second moving rod 241 movable along the radial direction of the accommodating 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 at 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 to 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 accommodating rod 10. The above limiting assembly has the advantages of simple structure and easy disassembly and assembly.

[0080] The first spring column 23 and the second spring column 24 are both arranged on the washer 20. The side wall of the washer 20 is provided with a first notch 21 and a second notch 22. The first notch 21 is arranged corresponding to the first spring column 23, and the second notch 22 is arranged corresponding to the second spring column 24. During the installation process, the first spring column 23 is rotated to the first notch 21 so that the first spring column 23 can drive the stopper rod 611 to move. During the disassembly process, the second spring column 24 is rotated to the second notch 22 so that the second spring column 24 can 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 arranged on the two straight rod sections of the U-shaped rod, the arc 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 section of the U-shaped rod, and the first clamping plate 11 and the arc section of the U-shaped rod together form a first clamping groove. The U-shaped rod is used to receive the terminal, which has the advantages of simple structure and easy operation.

[0082] In this embodiment, the accommodating cavity of the accommodating rod 10 is arranged on the straight rod section thereof.

[0083] The following is an explanation of the specific usage process of the fixed component:

[0084] During installation, the operator needs to place the containing rod 10 at the correct position of the grounding terminal and ensure that the opening portion of the containing rod 10 is aligned with the grounding terminal for subsequent device installation. Then, the first clamping plate 11 passes through the two straight rod sections of the containing rod 10 and directly makes physical contact with the grounding terminal to ensure a good electrical connection.

[0085] Next, the operator introduces the down conductor into the contact area of ​​the first clamping plate 11 to establish a connection through physical contact. At this time, the second clamping plate 12 is inserted to clamp and fix the down conductor.

[0086] Subsequently, the washer 20 is inserted into the accommodating 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 thereon faces the extension direction of the grounding terminal. This rotation action enables the first movable block 232 in 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 down conductor.

[0087] Next, the operator needs to screw the fastening ring 30 onto the end of the receiving rod 10 to ensure the stability of the entire device and the continuous contact between the grounding terminal and the down conductor.

[0088] In order to further enhance the clamping effect, the operator needs to press the column 51, and the column 51 drives the connecting rod 72 to move through the first connecting plate 75, so that the first protrusion 74 can move relatively. The second protrusion 63 and the first protrusion 74 together form an annular protrusion structure, and the stop ring 71 stops on the outside of the stop rod 611. Even if the fastening ring 30 and the washer 20 may become loose, the grounding terminal and the down conductor can be stably clamped.

[0089] During the process of loosening the clamp, the fastening ring 30 needs to be removed first, and then the operator needs to take out the gasket 20. When the gasket 20 moves to the position of the protective plate 13, the operator needs to rotate the gasket 20 and align the second notch 22 with the extension direction of the ground terminal, so that the second moving block 242 is squeezed onto the button 54, causing the spring 57 to disengage from the limiting shell 55, thereby canceling 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 of the containing rod 10, breaking the contact with the grounding terminal, and the second clamping plate 12 is also moved out to release the fixation of the down conductor. In this process, the second protrusion 63 is also automatically retracted into the inner cavity of the containing rod 10 as the two clamping blocks move, completing the entire disassembly process.

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

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

[0093] 1. The U-shaped rod and the combination of the first clamping plate 11 and the second clamping plate 12 thereon realize the simultaneous clamping and fixing of the grounding terminal and the down conductor. This design significantly improves the operating efficiency of the wiring set.

[0094] 2. The cylindrical structure inside the device is provided with a first protrusion 74 and a second protrusion 63. These protrusion structures form an annular protrusion, which can continue to maintain a stable clamping of the grounding terminal and the down conductor even when the fastening ring and the gasket are loose; this design greatly improves the reliability and anti-interference ability of the device, ensuring 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 drives the first protrusion 74 to open. This design makes the device installation process simpler and faster, reduces the operation time and difficulty, and improves the user experience.

[0096] 4. The column 51 can maintain the position of the second protrusion 63 when forming the annular protrusion, and the spring 57 transmits the fixing force of the column 51 to the first protrusion 74. Even if the gasket loosens and loses the limit on the first protrusion 74, the annular protrusion can still maintain stable fixation to the grounding terminal and the down conductor through the annular baffle and the column 51.

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