At the time of installation, the operator needs to place the accommodation bar 10 in the correct position of the ground terminal, ensuring that the opening portion of the accommodation bar 10 is aligned with the ground terminal for the subsequent installation of the device, and then the first clamping plate 11 passes through the two straight bar sections of the accommodation bar 10, making direct physical contact with the ground terminal, ensuring a good electrical connection.
Next, the operator introduces the down conductor to the contact area of the first clamping plate 11, establishes a connection by physical contact, and at this time, inserts the second clamping plate 12, and the second clamping plate 12 clamps and fixes the down conductor.
Subsequently, the washer 20 is inserted into the receiving bar 10, and it should be noted that when the washer 20 approaches the second clamping plate 12, the operator rotates the washer 20 such that the upper first notch 21 faces the extending direction of the ground terminal, and this rotation action causes the first moving block 232 in the washer 20 to drive the second protrusion 63 to protrude outwards by pushing the stop bar 611 and to be in stop-fit with the second clamping plate 12, thereby achieving a firm clamping of the ground terminal and the down conductor.
Next, the operator needs to screw the tightening ring 30 to the end of the receiving rod 10 to ensure stability of the whole device and continuous contact of the ground terminal with the down conductor.
To further enhance the clamping effect, the operator needs to press the cylinder 51, and the cylinder 51 drives the connecting rod 72 to move through the first connecting plate 75, so that the first protrusion 74 moves relatively, the second protrusion 63 and the first protrusion 74 form a ring-shaped protrusion structure together, and the stop ring 71 stops on the outer side of the stop rod 611, so that stable clamping of the ground terminal and the down conductor can be maintained even in the case of possible loosening of the fastening ring 30 and the washer 20.
In the process of releasing the clamping, the fastening ring 30 needs to be removed first, then, when the operator needs to take out the washer 20 and the washer 20 moves to the position of the protection plate 13, the operator needs to rotate the washer 20 to align the second notch 22 with the extending direction of the grounding terminal, so that the second moving block 242 presses the button 54, the elastic sheet 57 is separated from the limiting shell 55, and the limitation of the column body 51 is removed, in this way, the column body 51 returns to the initial position under the restoring force of the second spring 53, the limitation of the second protrusion 63 and the first protrusion 74 is released, and the second protrusion 63 and the first protrusion 74 are allowed to reset freely.
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 accommodating rod 10, the contact with the grounding terminal is broken, the second clamping plate 12 is also moved out, the fixation of the down conductor is released, and in the process, the second protrusion 63 is automatically accommodated back into the inner cavity of the accommodating rod 10 along with the movement of the two clamping blocks, so that the whole disassembly process is completed.
Thus, the whole operation process not only ensures the accurate measurement of the grounding resistance, but also ensures the rapid and safe assembly and disassembly of the equipment.
The application of the fixing component provided by the embodiment has the following beneficial effects:
1. Through the combination of the U-shaped rod and the first clamping plate 11 and the second clamping plate 12 on the U-shaped rod, the simultaneous clamping and fixing of the grounding terminal and the down conductor are realized, and the design remarkably improves the operation efficiency of the wiring suit.
2. The cylindrical structure inside the device is provided with a first bulge 74 and a second bulge 63, the bulge structures form an annular bulge, stable clamping of the grounding terminal and the down conductor can be continuously maintained even if the fastening ring and the gasket are loose, and the design greatly improves the reliability and the anti-interference capability of the device and ensures the stability under various working environments.
3. The gasket can be installed on the U-shaped rod at a specific angle, so that the second protrusion 63 is driven to be unfolded, the cylinder 51 drives the first protrusion 74 to be unfolded, and the device installation process is simpler, more convenient and quicker due to the design, the operation time and the difficulty are reduced, and the user experience is improved.
4. The post 51 can maintain the position of the second protrusion 63 when forming the annular protrusion, and the elastic piece 57 transmits the fixing force of the post 51 to the first protrusion 74, so that the annular protrusion can maintain stable fixation of the ground terminal and the down conductor through the annular blocking piece and the post 51 even if the gasket loosens and loses the limit of the first protrusion 74.
5. The provision of the first and second scores 21, 22 on the gasket provides an accurate reference point to ensure that the gasket can be properly installed or removed at a specific angle, and the second protrusion 63 will not be able to be repositioned if the gasket cannot be removed from the U-shaped bar at a specific angle, effectively preventing the release of the clamping of the post 51 when the gasket is removed due to vibration or other unexpected factors, ensuring long-term stable use of the device.
