Description

Technical Field

[0001] The utility model relates to the technical field of cable connectors, in particular to an underground high-density cable connector. Background Art

[0002] The underground cable connector is an important component in the power transmission system, which is used to connect underground cable lines to ensure the continuous supply of electricity. Existing underground cable connectors mainly use shells made of plastic or metal materials, and the cables are connected through metal connectors inside. These connectors are usually designed to be waterproof and dustproof to adapt to the wet and dusty environment underground.

[0003] In the prior art, the installation of cable connectors usually involves digging the ground, stripping and cleaning the cable heads, and fixing the cables to the connectors using specific mechanical tools. After that, the connection parts need to be sealed with encapsulating materials such as epoxy resin to ensure the sealing and protection of the connection. These steps require the operators to have professional skills, and require a long construction time and more auxiliary equipment at the construction site.

[0004] Although the existing cable connector design can meet the basic power transmission and protection requirements to a certain extent, there are still some shortcomings in practical applications. Especially in areas with high-density cable layout, the limitations of traditional connectors in terms of size and installation complexity are particularly prominent. In addition, traditional materials are often difficult to achieve optimal durability in terms of protection performance, especially long-term reliability in extreme environments remains a challenge.

[0005] In summary, although the existing underground high-density cable connector technology has shown its effectiveness in many years of application, its defects in operation convenience, protection effect and maintenance have gradually become apparent. Technological innovation is urgently needed to solve these problems in order to adapt to the modern power system's demand for high efficiency and high reliability. Utility Model Content
