Abstract

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.

[0011] The present invention will be further described below in conjunction with the drawings

[0012] Such as figure 1 with 2 As shown, the three-layer sealed wiring structure includes a stepped sleeve seal 1, an O-ring seal 2, a sealing nut 3, and a wire 9. The sleeve seal 1 is divided into an upper step 4 and a lower step 5. The height of the upper step 4 is higher than the height of the lower step 5, an O-shaped sealing ring 2 is sleeved on the outer surface of the lower step 5 of the sleeve seal 1, and a sealing nut 3 is provided on the outer side of the O-shaped sealing ring 2. A hollow square seat 6 is fixedly connected to the housing of the junction box, a through hole is provided on the rear wall 7 of the square seat 6, and the wire 9 passes through the sealing nut 3, the sleeve seal 1, the square in turn. Type seat 6 is connected with the circuit inside the junction box; an external thread is provided on the outside of the square seat 6, an internal thread is provided on the inside of the sealing nut 3, and the side wall 8 of the square seat 6 is sleeved on the O-shaped seal The outer side of the ring 2 wraps the sleeve seal 1 and the O-shaped seal ring 2, and the upper step 4 of the sleeve seal 1 is closer to the rear wall 7 of the square seat 6. The sealing nut 3 is fitted with threads Press the square seat 6 tightly. The sleeve seal 1 is provided with an upper step 4, which can play a role in resisting the O-ring 2 so that the O-ring 2 will not fall off the sleeve seal 1 during the rotation and tightening process of the sealing nut 3 Falling off strengthens the sealing effect and prolongs the service life.
