[0002] Prefabricated cable accessories are devices used for cable connection, protection, and grounding, and are widely used in power systems. Unlike traditional field-made cable accessories, prefabricated cable accessories are mostly manufactured in the factory, requiring only simple installation by the user on site.

[0003] Existing prefabricated cable accessories typically use a plug-in mechanism during installation. However, traditional plug-in mechanisms often use plastic springs to achieve a limiting effect. This method is prone to breakage after repeated plugging and unplugging, making it unsuitable for repeated use. Utility Model Content
