Description

Technical Field

[0001] This utility model relates to the field of cable joint technology, and in particular to a waterproof sealing component for a high-voltage cable joint. Background Technology

[0002] In power transmission systems, high-voltage cables serve as a crucial carrier for electrical energy transmission, and the waterproof sealing performance of their joints directly affects the safe and stable operation of the power system. With the continuous development of the power industry, the application scenarios for high-voltage cables are becoming increasingly complex, requiring them to cope not only with rain and humidity in the daily environment but also with the challenges of complex aquatic environments such as groundwater and accumulated water. Currently, traditional waterproof sealing structures for high-voltage cable joints have many shortcomings. Some joints rely solely on simply wrapping waterproof tape or applying sealant. Over long-term use, the waterproof tape is prone to aging and cracking, and the sealant may peel off or fail due to environmental factors, making it easy for moisture to seep into the joint. Water erosion at the joint accelerates the aging of the cable insulation, increases the risk of partial discharge, and in severe cases, can even cause short circuits, leading to widespread power outages and significant losses to power supply and daily life. Furthermore, existing waterproof sealing structures are inconvenient to install and maintain, with cumbersome installation processes, inconsistent sealing performance, and high repair and replacement costs. Therefore, this project aims to develop a high-voltage cable joint waterproof sealing component with a reasonable structure, reliable waterproof performance, and easy installation and maintenance to meet the stringent requirements of modern power transmission systems for the safe operation of high-voltage cables.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a waterproof sealing assembly for a high-voltage cable connector, comprising two connectors 1, each connector 1 having a rubber ring 15 fitted on one side, each connector 1 having a ring groove 18 on its outer wall, and a waterproof mechanism installed between the two connectors 1; The waterproof mechanism includes two waterproof shells 12, each of which is fixedly connected to a connecting block 13 on its outer side. Each waterproof shell 12 has two rectangular slots 23 on its upper surface, and a spring assembly is fixedly installed in each rectangular slot 23. The spring assembly includes a plate 20 and a spring assembly 21; Pick up connector 1 and carefully fit the rubber ring 15 onto one side of connector 1. Ensure that the rubber ring 15 is fully embedded in the designated position and fits tightly against the inner wall of connector 1 without any looseness or twisting. Its sealing effect can effectively prevent moisture from seeping into connector 1. Repeat the above steps to complete the installation of the other connector 1 and rubber ring 15. The lower end of the spring assembly 21 is fixedly connected to the inner surface of the rectangular slot 23 on the upper surface of the waterproof housing 12. Adhesive or other fixing methods can be used to ensure a secure connection. Then, the plate 20 is fixedly connected to the upper end of the spring assembly 21 to ensure that the spring assembly can expand and contract normally after installation, providing elastic pressure for subsequent sealing. The spring assemblies are installed in the two rectangular slots 23 of each waterproof housing 12 using the same method. The pin 17 is fixedly connected to the lower surface of the connecting block 13. Since the pin 17 is elastic, attention should be paid to its elastic direction and position during installation to ensure smooth engagement later. A slot 16 is made on the connecting block 13 at the lower end. The size and shape of the slot 16 must match the corresponding pin 17 to achieve snap-fit ​​fixation. Furthermore, the fixing frames 19 are fixedly connected to both sides of the inner wall of the waterproof housing 12, ensuring that the fixing frames 19 are accurately positioned. Then, the fixing frames 19 on the waterproof housing 12 are fixedly connected to the annular groove 18 on the outer wall of the connector 1, which can be tightened with screws or other connectors to ensure a tight, gapless connection between the waterproof housing 12 and the connector 1. This step is repeated to complete the installation of both waterproof housings 12 and their corresponding connectors 1. Furthermore, the connector 3 is placed between the two waterproof shells 12, so that the plate assembly 31 on the outer wall of the connector 3 corresponds to the structure inside the waterproof shell 12. Since the plate assembly 31 is elastic, it can be pressed appropriately during installation to allow it to smoothly enter the predetermined position; Furthermore, snap one end of connector 2 4 into connector 1 3, ensuring a secure and loose connection. During installation, care must be taken to ensure the elliptical shell 30 at one end of connector 2 4 aligns with surrounding components to avoid interference. Next, the connecting blocks 13 on the two waterproof shells 12 are aligned, so that the pins 17 are inserted into the corresponding slots 16, and the elasticity of the pins 17 is used to achieve a snap-fit ​​fixation. Check each connection part to ensure that the waterproof shell 12, connector 1, connector 3 and connector 4 are tightly connected without gaps, and that the spring assembly is in a normal compressed state, which can provide effective sealing pressure.

[0022] Working Principle: The waterproof sealing assembly for high-voltage cable joints achieves waterproofing through the coordinated action of multiple components. The rubber ring 15 inside connector 1, with its elasticity, tightly adheres to the cable, preventing moisture from seeping in through the gap between connector 1 and the cable. The waterproof shell 12 is fixed to the ring groove 18 of connector 1 via the fixing frame 19, forming an external protective layer that isolates external moisture. The spring assembly is compressed when the waterproof shell 12 is joined, and the elastic pressure generated by the spring assembly 21 is transmitted through the plate 20, ensuring a tight fit between the inner wall of the waterproof shell 12 and the joint components. Even if the joint is displaced by external force or environmental changes, the seal remains intact. The pin 17 of connector block 13 engages with the slot 16, ensuring a stable connection of the waterproof shell 12 and preventing water leakage at the connection point. The elastic plate assembly 31 of connector one 3 fills the internal gaps of the waterproof shell 12, enhancing the seal and providing cushioning and shock absorption. The elliptical shell 30 of connector two 4 works closely with other components to enhance the overall waterproof performance, ensuring the safe operation of the high-voltage cable joint in harsh environments.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
