AI Technical Summary
In existing technologies, when wire harnesses are guided through pre-set conduits, it is difficult to introduce new wire harnesses. Operators cannot visually observe the wiring, which may cause the wire harnesses to bend or cross, increasing safety hazards such as the risk of spontaneous combustion.
Lead posts are installed inside the distribution cabinet. The lead posts are equipped with mounting slots and limiting rings. The limiting rings achieve visual guidance of the wire harness through a spring and pressure plate structure. By using limiting teeth and grooves to limit the position of the limiting rings, operators can directly observe and adjust the position of the wire harness.
It enables intuitive guidance and safe placement of wire harnesses, avoids bending and crossing of wire harnesses, reduces the risk of spontaneous combustion, simplifies the operation process and saves space.
