Description

Technical Field

[0001] This utility model relates to the field of cable processing, specifically to a connector for conductors of ultra-high voltage cables. Background Technology

[0002] The working principle of the vertical tower-type ultra-high voltage cable production line is as follows: Copper / aluminum conductors (single-core or multi-core stranded conductors) are drawn out from the wire feeding device at the bottom or side of the tower. After the conductors undergo pretreatment (such as surface cleaning and preheating), they enter the extruder inside the tower, where cross-linked polyethylene (XLPE) insulation material is uniformly extruded and coated onto the surface of the conductor to form an initial insulation layer. Subsequently, the insulated conductor enters the high-temperature and high-pressure cross-linking tube inside the tower. Through the high-temperature environment provided by superheated water or steam, the insulation material undergoes a chemical cross-linking reaction, forming a stable insulation structure that is heat-resistant, aging-resistant, and has excellent electrical insulation performance. The entire process relies on the continuous production characteristics of the vertical tower structure to ensure the stability of insulation cross-linking, shielding, and sheathing, meeting the stringent requirements of ultra-high voltage cables for electrical performance and mechanical strength. Ultra-high voltage cables have extremely high performance requirements, and vertical tower production lines are equipment specifically designed for producing them. Vertical tower production can reduce the impact of gravity on product eccentricity, effectively solving the problem of difficult-to-control eccentricity, ensuring superior product performance, and guaranteeing consistent and reliable product quality. During the production process, if it is necessary to change the type of cable being produced or if other situations arise that require splicing and pulling the cables within the tower, a connection structure is needed to quickly connect the conductors. Existing traditional connection structures are complex, have long connection operation times, cannot guarantee quality and reliability, and are inconvenient to operate. Utility Model Content

[0003] The purpose of this invention is to provide a connector for ultra-high voltage cable conductors to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a connector for ultra-high voltage cable conductors is provided, including a snap-fit ​​structure. A crimp connector is installed on one side of the snap-fit ​​structure, and a connecting rod assembly is installed on the other side of the snap-fit ​​structure. A hook connector is fixedly provided on the bottom outer side of the crimp connector, and a guide groove and a hook groove are provided on the outer side of the surface of the snap-fit ​​structure. A compression spring is fixedly provided on the surface of the connecting rod assembly, and a force-bearing plate is fixedly provided on the top of the compression spring.

[0005] Furthermore, both the crimp connector and the connecting rod assembly have connecting ends on their outer sides, and a protective sleeve is fixedly provided on the outer ring surface of the crimp connector. At the same time, the protective sleeve covers the snap-fit ​​structure and the outer circumferential wall of the connecting rod assembly that are mated together.

[0006] Furthermore, a pressure seat is installed in the middle of the bottom of the crimp connector, and five sets of hook joints are equidistantly arranged on the outer side of the pressure seat. At the same time, five sets of hook grooves are equidistantly opened on the surface of the snap-fit ​​structure, and a guide groove is opened on one side of each of the five sets of hook grooves.

[0007] Furthermore, the hook connector and hook groove are dovetail shaped, and the guide groove is rectangular. The hook connector passes through the guide groove and is locked inside the hook groove. A compression hole is provided in the middle of the snap-fit ​​structure.

[0008] Furthermore, the bottom of the snap-fit ​​structure is provided with three sets of docking grooves at equal intervals, and docking pieces are screwed and fixed inside the docking grooves. Both the docking pieces and the docking grooves are isosceles trapezoids.

[0009] Furthermore, the mating piece is fixedly disposed on the outer circumference of the connecting rod assembly, and the force-bearing piece on the connecting rod assembly is disposed opposite to the pressure seat. At the same time, after the pressing connector and the snap-fit ​​structure are snapped together, the pressure seat compresses the compression spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The five sets of hooks on the crimp connector are inserted into the five sets of guide grooves on the snap-fit ​​structure. During the insertion of the hooks into the guide grooves, the pressure seat compresses the force-bearing plate and the compression spring. Rotating the crimp connector allows the five sets of hooks to be inserted into the five sets of hook grooves. Utilizing the friction between the hook grooves and the hooks, as well as the elasticity of the compression spring, a stable connection between the crimp connector and the snap-fit ​​structure is achieved. This allows for convenient connection of two cable connectors, ensuring continuous tower production. Compared with traditional connection structures, this not only improves production efficiency but also optimizes product quality and reduces costs. Attached Figure Description

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.

[0014] Please see Figure 1-5 This utility model provides a connector for ultra-high voltage cable conductors, including a snap-fit ​​structure 3. A crimp connector 1 is installed on one side of the snap-fit ​​structure 3, and a connecting rod assembly 4 is installed on the other side of the snap-fit ​​structure 3. A hook connector 12 is fixedly provided on the bottom outer side of the crimp connector 1. A guide groove 31 and a hook groove 32 are provided on the outer side of the surface of the snap-fit ​​structure 3. A compression spring 41 is fixedly provided on the surface of the connecting rod assembly 4, and a force-bearing plate 42 is fixedly provided on the top of the compression spring 41.

[0015] Working Principle: This snap-fit ​​structure 3 is suitable for connecting conductors of ultra-high voltage cables. It is used in the production line of a vertical tower to manufacture large-section, thick-insulated, ultra-high voltage conductors. In the event of a power outage, while wearing protective gloves, hold the crimp connector 1 and insert the five sets of hook connectors 12 on the crimp connector 1 into the five sets of guide grooves 31 on the snap-fit ​​structure 3. During this insertion, the pressure seat 13 compresses the force-bearing plate 42 and the compression spring 41. Rotating the crimp connector 1 allows the five sets of hook connectors 12 to be inserted into the five sets of hook grooves 32. Utilizing the friction between the hook grooves 32 and the hook connectors 12, as well as the elasticity of the compression spring 41, a stable connection is achieved between the crimp connector 1 and the snap-fit ​​structure 3. This allows for convenient connection of two cable connectors, ensuring continuous production of the vertical tower. Compared to traditional connection structures, this not only improves production efficiency but also optimizes product quality and reduces costs.

[0016] In a preferred embodiment, both the crimp connector 1 and the connecting rod assembly 4 are provided with connecting ends 2 on their outer sides, and a protective sleeve 11 is fixedly provided on the outer ring surface of the crimp connector 1. At the same time, the protective sleeve 11 covers the snap-fit ​​structure 3 and the outer circumferential wall of the connecting rod assembly 4 that are mated together.

[0017] A pressure seat 13 is installed in the middle of the bottom of the crimp connector 1, and five sets of hook connectors 12 are equidistantly arranged on the outer side of the pressure seat 13. At the same time, five sets of hook grooves 32 are equidistantly opened on the surface of the snap-fit ​​structure 3, and a guide groove 31 is opened on one side of each of the five sets of hook grooves 32.

[0018] The hook connector 12 and the hook groove 32 are dovetail shaped, and the guide groove 31 is rectangular. At the same time, the hook connector 12 passes through the guide groove 31 and is locked inside the hook groove 32. The snap-fit ​​structure 3 has a compression hole 33 in the middle.

[0019] As a preferred embodiment, the bottom of the snap-fit ​​structure 3 is provided with three sets of mating grooves 34 at equal intervals. The mating grooves 34 are screwed and fixed with mating pieces 43. Both the mating pieces 43 and the mating grooves 34 are isosceles trapezoids.

[0020] The mating piece 43 is fixedly mounted on the outer circumference of the connecting rod assembly 4, and the force-bearing piece 42 on the connecting rod assembly 4 is positioned opposite to the pressure seat 13. After the pressing connector 1 and the snap-fit ​​structure 3 are snapped together, the pressure seat 13 compresses the compression spring 41.

[0021] like Figure 1-5 As shown: Wearing protective gloves, one can hold the crimp connector 1 and insert its five sets of hooks 12 into the five sets of guide grooves 31 of the snap-fit ​​structure 3. During the insertion process, the pressure seat 13 can simultaneously compress the force plate 42 and the compression spring 41. Simply rotating the crimp connector 1 allows the five sets of hooks 12 to be snapped into the five sets of hook grooves 32 respectively. With the help of the friction between the hook groove 32 and the hook 12 and the elastic force of the compression spring 41, a stable connection between the crimp connector 1 and the snap-fit ​​structure 3 can be quickly achieved. The connection of two cable joints can be conveniently completed without complicated procedures. Moreover, this connection method can adapt to the connection requirements of ultra-high voltage conductors with large insulation thickness and large cross-section, ensuring that the connection part has reliable stability in subsequent production or use, and meeting the stringent requirements of ultra-high voltage cable conductor connection for structural stability.
