Description

Technical Field

[0001] This utility model relates to the field of electrical connection equipment technology, and in particular to a telescopic jumper fixing device and a jumper bridge. Background Technology

[0002] A jumper wire is a device used in electrical systems to connect metal bodies to form a grounding protection. It eliminates potential differences by conducting current to prevent leakage accidents and ensure electrical safety. It is commonly used in distribution boxes to balance current distribution and ensure the normal operation of equipment. Jumper wires are mostly made of highly conductive copper or aluminum wire. Jumper wires require regular maintenance and should be kept away from the neutral wire to ensure long-term effectiveness.

[0003] In existing technology, when installing jumper cables, the outer locking mechanism is typically removed first, then the perforated connector is fixed, the jumper cable is passed through the screw to ensure it fits snugly against the cable tray, and finally, the locking mechanism is used to secure the connector to complete the jumper cable fixation. Because the installation or replacement of jumper cables requires the continuous removal and installation of the locking mechanism on the cable tray to fix the corresponding perforated connector, this increases the labor intensity and workload for workers replacing jumper cables, resulting in low replacement efficiency and a long replacement time.

[0004] Therefore, there is an urgent need to improve the fixing device for the jumper wire to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a telescopic jumper fixing device and jumper cable tray, which can stably assemble jumpers, reduce the labor intensity of personnel replacing jumpers, eliminate the need for repeated disassembly and installation of parts, make replacement more efficient, shorten replacement time, and facilitate operation and maintenance.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Telescopic jumper cable fixing device, including:

[0008] A telescopic installation module includes a connector and an elastic fixing component. The elastic fixing component is disposed in the middle of the connector and can be stretched and deformed to engage with a jumper wire.

[0009] A locking element is movably connected to the connecting element, and the locking element selectively fixes and presses against the elastic fixing assembly.

[0010] As an optional technical solution for the telescopic jumper fixing device, the elastic fixing component includes an elastic element, a slider, and a pull rod. The slider and the pull rod are pulled and mated together by the elastic element. The slider can be moved to open the slider and the pull rod. The slider and the pull rod are used to snap the jumper wire together.

[0011] As an optional technical solution for the telescopic jumper fixing device, the elastic element is set as a spring.

[0012] As an optional technical solution for the telescopic jumper fixing device, an insulating layer is provided on the top of the slider.

[0013] As an optional technical solution for the telescopic jumper fixing device, the slider and the pull rod are connected in the horizontal direction, and the slider can be pushed downward to form an angle with the end of the pull rod.

[0014] As an optional technical solution for the telescopic jumper fixing device, the connecting member is a bolt and the locking member is a nut.

[0015] A jumper cable tray includes a cable tray body and jumper wires, and further includes a telescopic jumper wire fixing device as described in any of the above, wherein the connector is fixed to the cable tray body, and the jumper wire passes through the locking member and engages with the elastic fixing component.

[0016] As an optional technical solution for the jumper cable tray, both ends of the cable tray body are provided with the telescopic jumper cable fixing device.

[0017] As an optional technical solution for the jumper cable tray, the heights of the two telescopic jumper fixing devices are on the same horizontal line.

[0018] As an optional technical solution for the jumper cable tray, each of the elastic fixing components is snapped with one or more of the jumper wires.

[0019] The beneficial effects of this utility model are:

[0020] This utility model discloses a telescopic jumper fixing device and a jumper cable tray cabinet. The telescopic jumper fixing device includes a telescopic installation module and a locking block. The telescopic installation module includes a connector and an elastic fixing component. The elastic fixing component is located in the middle of the connector and can be stretched and deformed to engage with the jumper. The elastic fixing component can be stretched by the operator to accumulate elastic potential energy for rebound. After stretching, the elastic fixing component has a gap for the jumper to engage. The connector is fixed to the cable tray body. To make the assembly of the jumper more stable, a locking component is added and movably connected to the connector. The locking component can selectively fix and press the elastic fixing component. Before installing or replacing the jumper, the locking component moves from its original position to a position slightly away from the elastic fixing component to give the elastic fixing component sufficient stretching space for the jumper to engage with the elastic fixing component. The jumper passes through the locking component and engages with the elastic fixing component. After installing or replacing the jumper, the locking component returns to its original position and presses it firmly, further stabilizing and fixing the jumper to the elastic fixing component to prevent the jumper from slipping or loosening. Simply move the locking component slightly to offset the snap-fit ​​position, and the operator can directly move the elastic fixing component to complete the snap-fit ​​of the jumper cable. After that, the locking component returns to its fixed position, avoiding repeated disassembly and installation of the locking component and connector, extending the service life of each part, and facilitating the operator's operation and control. It also prevents parts from being scattered or lost, reduces the labor intensity of the operators replacing the jumper cable, reduces the workload, makes the replacement more efficient, reduces the time spent on replacement, and requires less investment and is easy to operate and maintain.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] like Figure 1 and Figure 2As shown, this utility model discloses a telescopic jumper fixing device and a jumper cable tray. The jumper cable tray includes the telescopic jumper fixing device, a cable tray body 1, and a jumper wire 4. The telescopic jumper fixing device includes a telescopic installation module and a locking block. The telescopic installation module includes a connector 2 and an elastic fixing component 3. The elastic fixing component 3 is disposed in the middle of the connector 2. The elastic fixing component 3 can be stretched and deformed to engage with the jumper wire 4. The elastic fixing component 3 can be stretched by the operator to accumulate elastic potential energy for rebound. After stretching, the elastic fixing component 3 has a gap for the jumper wire 4 to engage. After the operator releases the pressure, the elastic fixing component 3 returns to its original shape, the gap is re-clamped, and the jumper wire 4 is fixed at the elastic fixing component 3. Connector 2 is fixed to the cable tray body 1. To make the assembly of jumper wire 4 more stable, locking member 5 is added and movably connected to connector 2. Locking member 5 can selectively fix and press elastic fixing component 3. Before installing or replacing jumper wire 4, locking member 5 moves from its original position to a position slightly away from elastic fixing component 3 so that elastic fixing component 3 has sufficient stretching space for jumper wire 4 to engage with elastic fixing component 3. Jumper wire 4 passes through locking member 5 and engages with elastic fixing component 3. After installing or replacing jumper wire 4, locking member 5 returns to its original position to press and further stabilize and fix jumper wire 4 to elastic fixing component 3, preventing jumper wire 4 from slipping or loosening.

[0030] Compared to existing technologies, this new method eliminates the need to completely remove the locking component 5 from the connector 2, and avoids waiting until the jumper cable 4 is replaced or installed before reinstalling the removed locking component 5. Instead, the locking component 5 is simply moved slightly to offset its snap-fit ​​position, and the operator directly moves the elastic fixing component 3 to snap the jumper cable 4 into place. After this, the locking component 5 returns to its fixed position. This avoids repeated removal and installation of the locking component 5 and connector 2, extending the service life of each component. It also facilitates operator control, prevents parts from being scattered or lost, reduces the workload of operators replacing the jumper cable 4, increases replacement efficiency, shortens replacement time, requires less investment, and is convenient to operate and maintain.

[0031] In this embodiment, the connector 2 can be a bolt, and the locking component 5 can be a nut. The bolt and nut are connected by a screw, which facilitates the assembly of the telescopic jumper fixing device and makes it easy to adjust the position of the nut to loosen and lock the telescopic installation module.

[0032] Specifically, the elastic fixing component 3 includes an elastic element, a slider 8, and a pull rod 7. The elastic element can be a spring 6. The slider 8 and the pull rod 7 are horizontally engaged and connected by the pull of the spring 6. The operator can push the slider 8 downward to open the slider 8 and the pull rod 7, forming an angle between the ends of the slider 8 and the pull rod 7. This angle is used to place and engage the jumper wire 4. Then, the operator releases the slider 8, and under the action of the spring 6, the slider 8 and the pull rod 7 return to their original position, re-engage and press the jumper wire 4. Finally, the installation or replacement of the jumper wire 4 is completed by tightening the lock nut.

[0033] Understandably, each elastic fixing component 3 can selectively snap on one or more jumper wires 4 according to the actual situation. Compared with the prior art, a single perforated connector can only be fixed by a limited number of jumper wires 4. The telescopic jumper wire fixing device in this application is not subject to this limitation and can snap on different jumper wires 4 from various angles, making wiring more convenient and smooth, and making it easier to sort out the lines during maintenance.

[0034] Furthermore, an insulating layer is provided on the top of the slider 8, which provides insulation protection for the part of the operator that comes into contact with the slider 8, so as to prevent the operator from accidentally getting an electric shock during operation and protect the operator's personal safety.

[0035] For example, both ends of the cable tray body 1 are provided with telescopic jumper fixing devices, and both ends of the longer jumper wire 4 are provided with telescopic jumper fixing devices for wiring. In this extended embodiment, telescopic jumper fixing devices can be installed at appropriate locations on the cable tray body 1 according to actual conditions. The telescopic jumper fixing devices are spaced at preset intervals to maintain high performance consistency and neat appearance of the cable tray. Specifically, the telescopic jumper fixing devices at both ends of the cable tray body 1 are at the same horizontal level, ensuring a neat and consistent wiring direction for the jumper wire 4, providing higher safety, avoiding the risk of short circuits caused by tangled wires, and facilitating future circuit inspection and maintenance.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
