Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, specifically a quick-disassembly cable connector for ring main units. Background Technology

[0002] In power systems, ring main unit cable connectors are crucial connection components. Primarily used inside ring main units, they ensure reliable electrical connections between cables and other electrical equipment within the unit. These connectors play an indispensable role in the entire power transmission and distribution process, and their design and manufacturing must adhere to stringent electrical standards and specifications to ensure the safety, stability, and efficiency of power transmission.

[0003] The existing patent announcement number CN208847372U discloses a cable connector for a ring main unit, including a connector body. A conductive head is fixed inside the connector body, and a self-powered wireless temperature sensor is sleeved on the conductive head. An insulating plug is sleeved on the self-powered wireless temperature sensor. The insulating plug is a hollow plug structure with one open end, and a concave cylinder is fixed inside the cavity of the insulating plug. The tail end of the conductive head is embedded in the concave cylinder, and a partial discharge shielding layer is sealed on the inner surface of the insulating plug. This utility model discloses a cable connector that houses a self-powered wireless temperature sensor and an insulating plug that matches the self-powered wireless temperature sensor. The insulating plug protects the self-powered wireless temperature sensor and the conductive head, providing protection against leakage and partial discharge. The self-powered wireless temperature sensor can collect the electric field energy at the conductive head inside the cable connector without requiring an external power supply.

[0004] While the above technical solutions offer protection against leakage and partial discharge, the lack of a quick-release design makes the maintenance process lengthy when cables or cable connectors in the ring main unit require maintenance, inspection, or replacement. For example, without a quick-release structure, various tools may be needed to loosen bolts and disassemble complex connections, significantly increasing maintenance time. Therefore, we provide a quick-release cable connector for ring main units. Utility Model Content

[0005] The purpose of this invention is to provide a quick-disassembly cable connector for ring main units to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-disassembly ring main unit cable connector, comprising a connector body, an inner end of the connector body on one side, connecting posts on the top and bottom sides of the connector body, magnetic blocks (first type) on the ends of the two connecting posts away from the connector body, a mating groove on the side of the inner end of the connector body near the connector body, magnetic blocks (second type) in the two mating grooves, mounting grooves on both sides of the inner wall of the inner end of the connector body, a snap-fit ​​groove through one side of each mounting groove, mounting sliders on both sides of the connector body, spring pieces inside each mounting slider, a locking block at one end of each spring piece, and a protective mechanism on the end of the connector body away from the inner end of the connector body.

[0007] As a further preferred embodiment of this technical solution, the protective mechanism includes an insulating rubber sleeve. The insulating rubber sleeve has a threaded portion on the outside of one end near the connector body.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a quick-detachable ring main unit cable connector includes a connector body 11. An inner end 12 is provided on one side of the connector body 11. Connecting posts 13 are provided on the top and bottom sides of the connector body 11. The connector body 11 is mated to the inner end 12. Connecting posts 13 are fixedly connected to the top and bottom sides of the connector body 11. Magnetic blocks 14 are provided at the ends of the two connecting posts 13 away from the connector body 11. A mating groove 15 is provided on the side of the inner end 12 near the connector body 11. Magnetic blocks 16 are provided in both mating grooves 15. Magnetic blocks 14 are fixedly connected to the ends of the connecting posts 13 away from the connector body 11. Magnetic blocks 16 are fixedly connected to the mating grooves 15. Installation grooves 17 are provided on both sides of the inner wall of the inner end 12. A magnetic block 16 is provided on one side of each of the two installation grooves 17. A through slot 18 is provided. Both sides of the connector body 11 are provided with mounting sliders 19. Magnetic block 14 is mated in the mating groove 15 and magnetically contacts magnetic block 16. Mounting sliders 19 are fixedly connected to both sides of the connector body 11. Spring pieces 110 are provided inside the two mounting sliders 19. One end of each spring piece 110 is provided with a locking block 111. The mounting sliders 19 are slidably connected to the inner wall of the mounting groove 17. One end of the spring piece 110 is fixedly connected to the side of the inner wall of the mounting slider 19 away from the locking block 111. The other end of the spring piece 110 is fixedly connected to the locking block 111. The outside of the locking block 111 is slidably connected to the inner wall of the slot opened in the mounting slider 19. The end of the locking block 111 away from the mounting slider 19 is locked in the slot 18. A protective mechanism 2 is provided at the end of the connector body 11 away from the cabinet end 12.

[0024] In this embodiment, when the cable connector of the ring main unit needs to be installed and disassembled, the locking blocks 111 on both sides of the connector body 11 should be pressed down so that they are recessed into the mounting slider 19, ensuring that the outer surface of the locking blocks 111 does not protrude from the mounting slider 19. The spring piece 110 will be compressed and deformed by the locking blocks 111, connecting the connector body 11 to the inner end 12 of the cabinet. The mounting slider 19 will slide in the mounting groove 17 to ensure stability during the connection installation. After the connector body 11 is connected to the inner end 12 of the cabinet, the locking blocks 111 will lose the squeezing force from the mounting groove 17. Therefore, the spring piece 110 releases its elasticity to push the locking blocks 111 into the locking groove 18, and the connector... The main body 11 and the inner end 12 of the cabinet will be fixed and limited. In addition, the magnetic block 14 will make magnetic contact with the magnetic block 2 16 to further ensure the stable connection between the connector body 11 and the inner end 12 of the cabinet. When it is necessary to quickly disassemble the connector body 11 and the inner end 12 of the cabinet, simply press the locking blocks 111 on both sides of the inner end 12 of the cabinet. As a result, the locking blocks 111 will be recessed into the mounting slider 19. Then, the spring piece 110 will be squeezed again to ensure that the locking blocks 111 are completely recessed into the mounting slider 19. After that, the connector body 11 can be pulled out from the inner end 12 of the cabinet. Compared with the traditional disassembly method of using various tools to loosen the bolts, the disassembly time is reduced.

[0025] like Figures 1-4 As shown, the protective mechanism 2 includes an insulating rubber sleeve 21. The insulating rubber sleeve 21 has a threaded portion 22 on the outside of one end near the connector body 11. The insulating rubber sleeve 21 is threadedly installed to the connector body 11 on the side away from the cabinet end 12 through the threaded portion 22. A wire harness 24 is provided inside the insulating rubber sleeve 21.

[0026] In this embodiment, the insulating rubber sleeve 21 can effectively isolate the wires in the wire harness 24 from external conductive objects and wires with different potentials inside the wire harness 24. In addition, the rubber sleeve can also serve as a barrier to reduce the risk of electric shock and protect the life safety of operators.

[0027] This utility model provides a quick-disassembly cable connector for ring main units, and its working principle is as follows:

[0028] When installing and removing the cable connector from the ring main unit, press the locking blocks 111 on both sides of the connector body 11 with both hands simultaneously, so that they are fully retracted into the mounting slider 19. Ensure that the outer surface of the locking block 111 is flush with the slider and avoid protrusion. At this time, the spring 110 is compressed and provides the unlocked state. Align the connector body 11 with the end 12 inside the cabinet and push it in smoothly along the mounting groove 17, keeping the push in a straight line and avoiding tilting. Ensure that the mounting slider 19 slides smoothly in the groove. When the connector is fully inserted, the locking blocks 111 lose the squeezing force of the groove, and the spring 110... The spring rebounds, pushing the locking block 111 outward and embedding it into the locking groove 18. At this time, the connector body 11 and the inner end 12 of the cabinet are firmly locked. A light pull test confirms that there is no looseness. When disassembly is required, press the locking blocks 111 on both sides of the inner end 12 of the cabinet with both hands at the same time, so that they retract back into the installation slider 19. The spring piece 110 is deformed by pressure, and the locking block 111 disengages from the locking groove 18, releasing the locked state. While maintaining the pressing state, smoothly pull out the connector body 11 along the direction of the slide groove. After complete separation, release the locking block 111, and the spring piece 110 returns to its natural state for the next installation.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
