AI Technical Summary
Traditional equipotential isolators suffer from difficulties in disassembly and assembly due to integrated welding or fixed threaded connections at the end of the housing, which can easily damage the threaded structure. Furthermore, the protective sleeve cannot flexibly adapt to the length requirements of different installation scenarios, increasing production and inventory costs.
The locking assembly consists of a rotating locking sleeve and a movable plate, which, combined with a threaded fit, enables quick assembly and disassembly. The length of the protective sleeve can be flexibly adjusted through the sliding fit between the outer and inner protective sleeves and the limiting guide.
It enables quick assembly and disassembly, reduces wear on threaded structures, lowers production and inventory costs, adapts to the needs of different installation scenarios, and ensures structural stability and cable protection reliability.
