Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a detachable cable accessory and an auxiliary assembly and testing device thereof. Background Art

[0002] Power cable accessories, especially those used for power cable terminals, intermediate joints and other equipment or components related to cable connections, are an indispensable part of the cable system. These accessories not only ensure the safety of cable connections, but also improve the reliability of the entire system. When two sections of cable need to be connected, intermediate joint cable accessories are usually used.

[0003] Most of the existing intermediate joint cable accessories adopt cold-pressed connection or hot-pressed connection. Although the traditional cold-pressed connection or hot-pressed connection can provide good electrical connection and mechanical stability, it is often difficult to separate again after connection due to its fixed connection method. This limits the flexibility of the cable accessories in actual use, but is not convenient enough when frequent disassembly or inspection is required. Once the cable is connected, if the cable needs to be readjusted or replaced, the original connection point must be destroyed and then a new connection point must be made. Such operation is time-consuming and laborious, and sometimes causes unnecessary waste of resources. In addition, in some special application scenarios, such as temporary wiring or occasions requiring regular maintenance, the reusability and quick disassembly and assembly capabilities of cable accessories become particularly important.

When connecting, the cable connector is inserted into the inner side of the connecting sleeve 101 through the openings at the left and right ends of the connecting sleeve 101 to connect with each other. A plurality of unit crimping plates 105 are evenly connected around the center of the intermediate joint 1. The unit crimping plates 105 are made of good conductive material and can slide along the horizontal fitting groove 104. The outer sides of the left and right ends of the intermediate joint 1 are screwed with a pressing sleeve 3 through threads.

The top pressing sleeve 3 pushes the unit crimping plate 105 to move toward the center of the middle joint 1 through the conical top pressing surface 303 and the top pressing inclined surface 107, so as to clamp and fix the cable joints that are nested and inserted into the connecting sleeve 101 and docked with each other through the surrounding unit crimping plate 105, and then the arc-shaped The clamping plate 8 moves so that the detection probe 806 is inserted into the detection slot 103, so that the resistance of the cable connection is directly detected by the resistance sensor 807, so as to detect the cable connection. At the same time, the roller motor 705 drives the clamping roller 703 to rotate in the opposite direction to pull the connected cable to move in the opposite direction, and the reverse torque of the clamping roller 703 is tested by the torque sensor 704, so as to detect the connection strength of the cable. After the detection is completed, the electric telescopic rod 801 drives the arc clamping plate 8 to loosen the middle joint 1, and at the same time, the telescopic connecting rod 702 drives the clamping roller 703 to move and loosen the clamped cable, so that the auxiliary assembly frame 7 can be removed as a whole, and then the insulating sleeves 4 on both sides are slid toward the center along the cable to make the insulating sleeves on the left and right sides The tubes 4 are assembled with each other through the interlocking connecting ring 601. At this time, the connecting sealing groove 602 is embedded in the connecting sealing ring 603 of the opposite side interlocking connecting ring 601 to ensure the sealing of the tooth connection. At the same time, the interlocking locking block 605 is embedded in the interlocking locking groove 604. Then, by rotating the insulating sleeves 4 on both sides in the opposite direction, the interlocking locking block 605 is embedded in the rotating locking groove 606 through the interlocking locking groove 604 to complete the connection of the interlocking connecting ring 601. Then, the sealing airbag 501 is inflated through the inflation connecting valve 502 to expand it and fill the cable connecting sleeve 5 to maintain the sealing. Then, electrical insulating oil is injected into the insulating sleeve 4 through the liquid filling connecting valve, so that the intermediate joint 1 is wrapped with the insulating oil to form an insulating protection structure, thereby completing the cable connection work.

[0049] The detachable cable accessory and the auxiliary assembly test device provided by the present invention connect the cables through the intermediate joint 1. When the cable joint is connected, the cable joint is inserted into the inner side of the connecting sleeve 101 through the openings at the left and right ends of the connecting sleeve 101 to connect with each other. When the pressing sleeve 3 rotates, it is synchronously translated along the horizontal direction of the intermediate joint 1 through the thread. The pressing sleeve 3 is translated toward one side of the unit crimping plate 105, and the unit crimping plate 105 is pushed to move toward the center of the intermediate joint 1 through the conical pressing surface 303 and the pressing inclined surface 107, so as to clamp the unit crimping plate 105 arranged around it. The cable connectors that are fixedly nested and connected to each other in the connecting sleeve 101 are fixed to complete the connection of the cable. A plurality of unit crimping plates 105 arranged around the connection sleeve can ensure mechanical strength and good conductivity. The unit crimping plates 105 can be loosened by rotating the top pressing sleeve 3 in the opposite direction to separate the connected cable connectors from each other. Therefore, the connection or separation of the cable can be completed by rotating the top pressing sleeve 3, which is convenient for reuse and avoids loss caused by disassembly. It is more flexible and convenient to use for application scenarios that require temporary wiring or frequently change line layout.
