[0002] Electrical bridging primarily refers to establishing a grounding metal connector (such as a conductor, round steel, flat steel, or flat copper) between two metal bodies (e.g., cabinets, cable trays, cable ducts, reinforcing bars, metal pipes, etc.). This is typically required when the grounding busbar encounters an obstacle (e.g., expansion joints or settlement joints in buildings), or when metal components or pipes are used as grounding wires and require welding. Its function is to reduce the impedance of the bridging conductor, avoid electromagnetic interference caused by the bridging conductor, thereby improving the reliability and safety of the electrical system.

[0003] Existing jumpers for distribution network lines, while able to limit cable movement through cable trays, have poor limiting effect and limited applicability. Furthermore, relying solely on grounding nails makes them unsuitable for various scenarios, and the grounding effect through grounding nails alone is poor, hindering widespread adoption.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a jumper for a distribution network line, including a left outer shell 1, a copper plate 2 on the top of the left outer shell 1, a right outer shell 3 on one side of the left outer shell 1, a demagnetizing component 4 inside the left outer shell 1, a limiting component 5 at the bottom of the demagnetizing component 4, and a grounding mounting component 6 on one side surface of the left outer shell 1.

[0022] Specifically, the limiting component 5 includes a side plate 51, a threaded hole 52, a screw 53, a clamping block 54, a limiting block 55, a fixing block 56, and a protective ring 57. The bottom of the demagnetizing component 4 is provided with a limiting block 55, and a side plate 51 is provided on one side of the limiting block 55. A threaded hole 52 is opened inside the side plate 51, and a screw 53 is provided inside the threaded hole 52. A clamping block 54 is provided at one end of the screw 53. A protective ring 57 is provided between the side plate 51 and the limiting block 55, and a fixing block 56 is provided on the inner side of the protective ring 57.

[0023] By adopting the above technical solution, when using the limiting component 5, the cable is first passed through the inside of the protective ring 57. The protective ring 57 protects the outer surface of the cable, preventing the cable surface from rubbing against the surface of the limiting block 55 when the cable is pulled, thus avoiding damage to the cable surface. When further limiting of the cable is required, the screw 53 can be rotated by the handwheel, which will further drive the clamping block 54 to move closer to the cable side until the clamping block 54 and the fixing block 56 contact the cable surface, thereby completing the further limiting of the cable, making the cable more secure and stable during use, and also expanding the applicable range of the device.

[0024] Specifically, the bottom of the clamping block 54 is provided with a protrusion, the bottom of the limiting block 55 is provided with a guide groove, and a bearing is provided at the contact point between the screw 53 and the clamping block 54.

[0025] By adopting the above technical solution, when the clamping block 54 moves, the protrusion will move synchronously in the guide groove, thereby ensuring the directionality of the movement of the clamping block 54 and improving the stability of the movement of the clamping block 54.

[0026] In this embodiment, when using the limiting component 5, the cable is first passed through the protective ring 57. The protective ring 57 protects the outer surface of the cable, preventing the cable surface from rubbing against the surface of the limiting block 55 and causing damage to the cable surface when it is pulled. When further limiting the cable is needed, the screw 53 can be rotated by the handwheel, which will further drive the clamping block 54 to move closer to the cable until the clamping block 54 and the fixing block 56 contact the cable surface, thereby completing the further limiting of the cable and making the cable more secure and stable during use. At the same time, it also expands the applicability of the device. When the clamping block 54 moves, the protrusion will move synchronously in the guide groove, thereby ensuring the directionality of the movement of the clamping block 54 and improving the stability of the movement of the clamping block 54.

[0027] Example 2

[0028] The difference between this embodiment and embodiment 1 is that, specifically, the grounding mounting assembly 6 includes a fixed plate 61, a sliding groove 62, a slider 63, a movable rod 64, a locking hole 65, a mounting bracket 66, and a locking assembly 67. The fixed plate 61 is fixedly attached to one side surface of the left outer shell 1, and the locking assembly 67 is provided on one side of the fixed plate 61. The movable rod 64 is provided inside the locking assembly 67. The locking hole 65 is opened on one side surface of the movable rod 64, and the slider 63 is fixedly attached to the side surface of the movable rod 64 away from the locking hole 65. The sliding groove 62 is opened on the side surface of the fixed plate 61 near the slider 63, and the mounting bracket 66 is fixedly attached to the bottom of the movable rod 64.

[0029] By adopting the above technical solution, when using the grounding installation component 6, the length of the movable rod 64 is first adjusted according to the installation position of the device, and then the length of the movable rod 64 is locked by the locking component 67. Then the mounting bracket 66 is connected to the grounding line, thereby improving the grounding function of the device, making the grounding function more stable, and the installation and adjustment more flexible.

[0030] Specifically, the locking assembly 67 includes a limiting frame 671, a support frame 672, a spring 673, a limiting ring 674, and a locking rod 675. The limiting frame 671 is fixed to one side surface of the fixing plate 61, the support frame 672 is fixed to one side surface of the limiting frame 671, the locking rod 675 is provided inside the support frame 672, the limiting ring 674 is provided on the surface of the locking rod 675, and the spring 673 is sleeved on the surface of the locking rod 675.

[0031] By adopting the above technical solution, when using the locking component 67, the locking rod 675 is first pulled outward by the handle. At this time, the spring 673 is compressed under the action of the limiting ring 674, and the locking rod 675 cancels the limiting lock on the movable rod 64. At this time, the extension length of the movable rod 64 can be adjusted. After the adjustment is completed, the locking rod 675 is pulled out, and the locking rod 675 limits and locks the movable rod 64 again under the action of the spring 673, thereby improving the adjustment efficiency of the movable rod 64.

[0032] Specifically, the bottom of the mounting bracket 66 is provided with mounting holes, and bolts are installed inside the mounting holes.

[0033] By adopting the above technical solution, and through the cooperation of the mounting holes and bolts, it is easy for workers to connect the mounting bracket 66 to the grounding line, thereby making the grounding connection more stable and secure, and also expanding the application range of the device.

[0034] In this embodiment, when using the grounding installation component 6, the length of the movable rod 64 is first adjusted according to the installation position of the device. Then, the length of the movable rod 64 is locked by the locking component 67. The mounting bracket 66 is then connected to the grounding line, thereby improving the grounding function of the device, making the grounding function more stable, and the installation and adjustment more flexible. When using the locking component 67, the locking rod 675 is first pulled outward by the handle. At this time, the spring 673 is compressed under the action of the limiting ring 674, and the locking rod 675 releases the limiting lock on the movable rod 64. At this time, the extension length of the movable rod 64 can be adjusted. After the adjustment is completed, the locking rod 675 is released, and the locking rod 675 is again limited and locked by the spring 673, thereby improving the adjustment efficiency of the movable rod 64. Through the cooperation of the mounting hole and the bolt, it is easy for the staff to connect the mounting bracket 66 to the grounding line, thereby making the grounding connection more stable and firm, and also expanding the application range of the device.

[0035] The structure and operating principle of the left outer shell 1, copper plate 2, right outer shell 3 and demagnetizing component 4 in this utility model have been disclosed in the jumper for power distribution lines disclosed in Chinese patent application number 201921944812.6.

[0036] The working principle and usage process of this utility model: This utility model is designed for adjusting jumpers used in distribution network lines. When using the limiting component 5, the cable is first passed through the protective ring 57. The protective ring 57 protects the outer surface of the cable, preventing damage to the cable surface caused by friction between the cable surface and the limiting block 55 when the cable is pulled. When further limiting the cable, the screw 53 can be rotated by the handwheel, which further moves the clamping block 54 closer to the cable until the clamping block 54 and the fixing block 56 contact the cable surface, thereby completing the further limiting of the cable and making the cable more secure and stable during use. This also expands the applicability of the device. When the clamping block 54 moves, the protrusion moves synchronously in the guide groove, thus ensuring the directionality of the clamping block 54's movement and improving the stability of the clamping block 54's movement. This utility model is designed for adjusting jumpers used in distribution network lines. When using the grounding installation component 6... First, the length of the movable rod 64 is adjusted according to the installation position of the device. Then, the length of the movable rod 64 is locked by the locking component 67. Next, the mounting bracket 66 is connected to the grounding line, thereby improving the grounding function of the device, making the grounding function more stable, and the installation and adjustment more flexible. When using the locking component 67, the locking rod 675 is pulled outward by the handle. At this time, the spring 673 is compressed under the action of the limiting ring 674, and the locking rod 675 releases the limiting lock on the movable rod 64. At this time, the extension length of the movable rod 64 can be adjusted. After the adjustment is completed, the locking rod 675 is released, and the locking rod 675 locks the movable rod 64 again under the action of the spring 673, thereby improving the adjustment efficiency of the movable rod 64. Through the cooperation of the mounting hole and bolt, it is easy for the staff to connect the mounting bracket 66 to the grounding line, thereby making the grounding connection more stable and firm, and also expanding the application range of the device.
