Description

Technical Field

[0001] This utility model relates to the field of internal conical sleeve structure technology, and in particular to an internal conical sleeve. Background Technology

[0002] As a key component in electrical equipment, the inner tapered sleeve mainly undertakes important functions such as current conduction, insulation support, and equipment connection. Its performance directly affects the stable operation of the entire electrical system. However, in practical applications, existing inner tapered sleeves generally suffer from poor adaptability and insufficient safety, which seriously restricts their application effect in different electrical scenarios. Most existing systems use only one fixed conductive component and have a fixed connection method with external circuits, making it difficult to meet diverse circuit connection needs. When faced with wires and equipment interfaces of different specifications, additional adapters are often required, which not only increases installation complexity but may also lead to poor contact due to too many adapter links, affecting current conduction efficiency. At the same time, the connection structure between the sleeve and external components lacks universality, and different models of equipment require specific sleeves, increasing the cost and difficulty of equipment maintenance and replacement. Therefore, this application designs an inner tapered sleeve to solve the above problems. Utility Model Content
