Problems solved by technology
The invention discloses a three-layer sealed wiring structure comprising a lead. The three-layer sealed wiring structure is characterized in that the three-layer sealed wiring structure also comprises a sleeve sealing element with a step-shaped cross section, an O-shaped sealing ring and a sealing nut, wherein the sleeve sealing element is divided into an upper step and a lower step; the outer surface of the lower step of the sleeve sealing element is sheathed with an O-shaped seal ring; and the outer side of the O-shaped seal ring is provided with the sealing nut; a hollow square base is fixedly connected on the housing of a junction box; the rear wall of the square base is provided with a through hole; the outer side of the square base is provided with outer screw nuts; the inner side of the sealing nut is provided with inner screw nuts; the square base is sheathed on the outer side of the O-shaped sealing ring to cover the sleeve sealing element and the O-shaped seal ring; and the sealing nut is matched with the thread to tightly press the square base. The invention solves the problem that the contact position of the junction box and the lead has poor sealing effect, is easy to flood and has short circuit in the prior art. The invention provides a three-layer sealed wiring structure with simple structure, convenient use and better sealing effect.
