Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grounding terminal structure for connecting grounding cables, and in particular to a grounding terminal that can be quickly connected to the end of a cable. Background Technology
[0002] When an aircraft is parked, maintained, or resupplyed on the ground, a grounding cable is required to connect the equipment ports on the aircraft to the grounding terminal fixed on the ground in order to eliminate leakage current, static electricity, or radio frequency induced voltage on the aircraft, thereby preventing leakage current, static electricity, or radio frequency induced voltage from causing harm to personnel on the aircraft.
[0003] The structure of a certain grounding terminal is as follows: Figure 1 As shown, it includes an anchor rod 1, a top rod 2 fixed to the top of the anchor rod 1, and a crossbar 3 fixed to the right side wall of the upper end of the anchor rod 1. A threaded hole 4 is formed on the top surface of the crossbar 3. The method of using this grounding terminal with a grounding cable is as follows: S1. Workers insert anchor bolt 1 into the designated ground beforehand; S2. The worker takes out a grounding cable 5, fixes one end of the grounding cable 5 to the equipment port of the aircraft, and then supports the annular conductive ring 6 located on the other end of the grounding cable 5 on the top surface of the crossbar 3, ensuring that the center hole 7 of the annular conductive ring 6 is aligned with the threaded hole 4 on the crossbar 3. Figure 2 As shown, press the annular conductive ring 6 with your hand to keep it still; S3. The worker inserts screw 8 through the center hole 7 of the annular conductive ring 6 and threads it into the threaded hole 4 to fix the annular conductive ring 6 onto the crossbar 3. Figure 3 As shown, at this time, the leakage current, static electricity or radio frequency induced voltage on the aircraft flows sequentially through the grounding cable 5, the ring conductive ring 6, the crossbar 3, and the anchor rod 1, and finally flows into the ground. That is, the aircraft and the ground are at the same potential, thus effectively avoiding the leakage current, static electricity or radio frequency induced voltage from causing harm to the personnel on the aircraft.
[0004] However, while this grounding terminal can be used, it still has the following technical defects: In step S2, the center hole 7 of the annular conductive ring 6 of the grounding cable 5 needs to be aligned with the threaded hole 4 manually, and the worker also needs to press the annular conductive ring 6 down by hand. Then, in step S3, the worker needs to manually use a special tool to thread the screw 8 into the threaded hole 4 to fix the annular conductive ring 6. The whole operation is done manually, which not only increases the worker's workload, but also increases the connection time with the grounding cable, thereby greatly reducing the connection efficiency with the end of the grounding cable.
[0005] Therefore, there is an urgent need for a grounding terminal that can reduce the workload of workers and greatly improve the efficiency of connection with the end of the grounding cable. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a grounding terminal that can quickly connect to the end of a grounding cable, which reduces the workload of workers and greatly improves the efficiency of connecting to the end of a grounding cable.
[0007] The purpose of this utility model is achieved through the following technical solution: a grounding terminal that can quickly connect to the end of a cable, comprising an anchor rod, a top rod fixed to the top of the anchor rod, a crossbar fixed to the right side wall of the upper end of the anchor rod, a cylindrical platform welded to the top surface of the crossbar, the outer diameter of the cylindrical platform being equal to the diameter of the central hole of the annular conductive ring on the end of the grounding cable, a rectangular groove arranged along its axial direction being formed on the top surface of the cylindrical platform, a sliding groove communicating with the rectangular groove being formed on the left end face of the cylindrical platform, a movable block being slidably installed in the sliding groove, a horizontal spring being fixed between the movable block and the bottom of the sliding groove, and an inclined surface located directly below the rectangular groove being formed on the right end of the movable block; A wedge block is slidably installed in the rectangular groove. The bottom of the wedge block has a wedge-shaped surface, which is located directly above the inclined surface of the movable block. A mounting plate is fixedly installed on the top of the wedge block. Magnetic blocks are fixedly installed on the bottom surface of the mounting plate and at its left and right ends. A pull ring is fixedly installed on the top surface of the mounting plate. A vertical spring is sleeved on the outside of the wedge block. The upper and lower ends of the vertical spring are fixedly installed on the mounting plate and the cylindrical platform, respectively.
[0008] The cylindrical platform is an iron column.
[0009] The bottom of the anchor rod is fixed with a conical head.
[0010] The inclined surface of the movable block is parallel to the wedge surface of the wedge block.
[0011] The top surface of the cylindrical platform is provided with a recessed groove that communicates with the rectangular groove. The bottom end of the vertical spring is fixed to the bottom of the recessed groove, and the top end of the vertical spring is fixed to the bottom surface of the mounting plate.

Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 4-11As shown, a grounding terminal for quick connection of cable ends includes an anchor rod 1 and a top rod 2 fixed to the top of the anchor rod 1. A conical head is fixed to the bottom of the anchor rod 1, and a crossbar 3 is fixed to the right side wall of the upper end of the anchor rod 1. A cylindrical platform 9 is welded to the top surface of the crossbar 3. The cylindrical platform 9 is an iron column, and the outer diameter of the cylindrical platform 9 is equal to the diameter of the central hole 7 of the annular conductive ring 6 on the end of the grounding cable 5. A rectangular groove 10 is formed on the top surface of the cylindrical platform 9 along its axial direction. A sliding groove 11 connected to the rectangular groove 10 is formed on the left end face of the cylindrical platform 9. A movable block 12 is slidably installed in the sliding groove 11. A horizontal spring 13 is fixed between the movable block 12 and the bottom of the sliding groove 11. An inclined surface 14 located directly below the rectangular groove 10 is formed on the right end of the movable block 12.
[0015] A wedge block 15 is slidably installed in the rectangular groove 10. A wedge surface 16 is provided at the bottom of the wedge block 15. The wedge surface 16 is located directly above the inclined surface 14 of the movable block 12. A mounting plate 17 is fixedly provided at the top of the wedge block 15. Magnetic blocks 18 are fixedly provided on the bottom surface of the mounting plate 17 and at its left and right ends. A pull ring 19 is fixedly provided on the top surface of the mounting plate 17. A vertical spring 20 is sleeved on the outside of the wedge block 15. The upper and lower ends of the vertical spring 20 are fixedly provided on the mounting plate 17 and the cylindrical platform 9, respectively.
[0016] The inclined surface 14 of the movable block 12 is parallel to the wedge surface 16 of the wedge block 15. A recessed groove 21 connected to the rectangular groove 10 is provided on the top surface of the cylindrical platform 9. The bottom end of the vertical spring 20 is fixed to the bottom of the recessed groove 21, and the top end of the vertical spring 20 is fixed to the bottom surface of the mounting plate 17.
[0017] The working process of this utility model is as follows: S1. The worker inserts the conical head of the anchor rod 1 into the designated ground in advance to fix the anchor rod 1. S2. The worker takes out a grounding cable 5, fixes one end of the grounding cable 5 to the equipment port of the aircraft, and then fits the center hole 7 of the annular conductive ring 6 located at the other end of the grounding cable 5 onto the cylindrical platform 9, as shown. Figures 12-13 As shown, at this time, the top surface of the annular conductive ring 6 is flush with the lower surface of the groove 11. S3. The worker presses down on the mounting plate 17. The mounting plate 17 drives the wedge block 15 and the two magnetic blocks 18 to move downwards simultaneously. At the same time, the mounting plate 17 compresses the vertical spring 20 downwards. When the wedge surface 16 of the wedge block 15 presses against the inclined surface 14 of the movable block 12, the movable block 12 moves to the left along the slide groove 11 and pulls the horizontal spring 13 to the left. When the two magnetic blocks 18 are attracted and fixed on the cylindrical platform 9, the left end of the movable block 12 moves to the outside of the slide groove 11 and blocks the annular conductive ring 6 to prevent the annular conductive ring 6 from falling off the cylindrical platform 9, thus fixing the annular conductive ring 6 in place. Figures 14-15 As shown, at this time, the leakage current, static electricity or radio frequency induced voltage on the aircraft flows sequentially through the grounding cable 5, the ring conductive ring 6, the crossbar 3, and the anchor bolt 1, and finally flows into the ground. That is, the aircraft and the ground are at the same potential, thus effectively avoiding the leakage current, static electricity or radio frequency induced voltage from causing harm to the personnel on the aircraft. As can be seen from steps S2-S3, the worker only needs to first place the annular conductive ring 6 of the grounding cable 5 onto the cylindrical platform 9, and then press down the mounting plate 17 to allow the two magnetic blocks 18 on the mounting plate 17 to adhere and fix to the cylindrical platform 9. This allows the movable block 12 to extend from the sliding groove 11 and block the annular conductive ring 6, thereby fixing the annular conductive ring 6 in place. Therefore, this grounding terminal, compared to... Figures 1-3 The grounding terminal shown eliminates the need for manual pressing of the annular conductive ring 6 before screwing in the screw 8 to fix it, thus greatly reducing the workload of workers and shortening the connection time with the grounding cable 5, thereby greatly improving the connection efficiency with the tail end of the grounding cable 5.
[0018] S4. When the grounding cable 5 is to be removed, the specific operating steps are as follows: The worker pulls the pull ring 19 upwards, the pull ring 19 drives the mounting plate 17 to move upwards, the mounting plate 17 drives the wedge block 15 and the two magnetic blocks 18 to move upwards at the same time, the wedge surface 16 of the wedge block 15 gradually separates from the inclined surface 14 of the movable block 12. During the separation process, the movable block 12 retracts into the slide groove 11 under the elastic force of the horizontal spring 13, and the movable block 12 no longer blocks the annular conductive ring 6 of the grounding cable 5. At this time, the worker can remove the annular conductive ring 6 from the cylindrical platform 9, and then remove the grounding cable 5.
[0019] As can be seen from step S4, the worker only needs to pull the pull ring 19 upwards to retract the movable block 12 back into the slide groove 11, thus facilitating the worker to quickly remove the annular conductive ring 6 from the cylindrical platform 9, and consequently, to remove the grounding cable 5. Therefore, this grounding terminal, compared to... Figures 1-3 The grounding terminal shown does not require workers to use tools to unscrew the screw 8, which greatly facilitates workers in removing the grounding cable 5 after use.
[0020] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
