AI Technical Summary
Traditional wiring methods are prone to damage when passing through expansion joints, leading to a decrease in the safety and stability of the electrical system, inconvenient and costly construction and maintenance, and large space occupation.
The system employs pre-embedded electrical conduits and retractable conduit assemblies. The pre-embedded electrical conduits are fixed within the concrete components on both sides of the expansion joint. The conduit assembly consists of a multi-layered nested structure connected to a sliding structure, which adapts to the displacement of the expansion joint and absorbs vibration energy through reserved gaps, ensuring the safe installation of electrical wires.
It effectively protects wires from pulling, squeezing or bending, reduces the probability of failure, simplifies the construction process, improves wiring efficiency, enhances the safety and stability of electrical systems, and reduces maintenance costs.

Abstract
Claims
1. A new type of deformation joint wire threading device, comprising a pre-embedded electrical conduit (3), characterized in that: The pre-embedded electrical conduit (3) is installed in the concrete components (2) on both sides of the expansion joint (1) to fix and guide the electrical cable (4). A telescopic conduit assembly (5) is provided in the expansion joint (1). The electrical cable (4) passes through the pre-embedded electrical conduit (3) and the telescopic conduit assembly (5) to achieve safe installation at the expansion joint. The telescopic conduit assembly (5) is composed of multiple nested conduits (51). The adjacent inner and outer layers are connected by a sliding structure (52) and can freely expand and contract to adapt to the displacement changes of the expansion joint (1). A gap is reserved between the concrete component (2) and the telescopic conduit assembly (5) to absorb the vibration energy of the expansion joint (1) and reduce the impact on the wires by utilizing the telescopicity of the telescopic conduit assembly (5).
2. The novel deformed joint wire threading device of claim 1, wherein: The width of the gap reserved between the concrete component (2) and the retractable conduit assembly (5) is 5mm-10mm.
3. The novel deformed joint wire threading device of claim 1, wherein: The sliding structure (52) is a guide rail (521) on the outer wall of the inner conduit (51) that cooperates with the groove (522) on the inner wall of the outer conduit (51) to ensure that the retractable conduit assembly (5) can freely expand, contract and bend when the expansion joint (1) is displaced.
4. The novel deformed joint wire fish tape device of claim 1, wherein: The end of the pre-embedded electrical conduit (3) extends 3cm-5cm beyond the side of the concrete component (2) to facilitate nesting connection with the retractable conduit assembly (5).
5. The novel deformed joint wire fish tape device of claim 4, wherein: The diameter of the pre-embedded electrical conduit (3) is adapted to the end size of the retractable conduit assembly (5).
6. The novel deformed joint wire fish tape device of claim 1, wherein: The openings at both ends of the expansion joint (1) are sealed by expansion joint sealing components (6).
7. The novel deformed joint wire fish tape device of claim 1, wherein: There is a space for movement between the outside of the electrical cable (4) and the inner wall of the retractable conduit assembly (5).
