Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described

[0012] Such as figure 1 and 2 As shown, the three-layer sealed wiring structure includes a step-shaped sleeve seal 1, an O-ring 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 that of the lower step 5 , an O-ring 2 is sheathed on the outer surface of the lower step 5 of the sleeve seal 1 , and a sealing nut 3 is arranged outside the O-ring 2 . The shell of the junction box is fixedly connected with a hollow square seat 6, and the rear wall 7 of the square seat 6 is provided with a through hole, and the wire 9 passes through the sealing nut 3, the sleeve seal 1, the square Type seat 6, and connected with the circuit inside the junction box; external threads are provided on the outside of the square seat 6, internal threads are provided on the inside of the sealing nut 3, an...

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.

Description

technical field [0001] The invention relates to a sealing structure of wires, in particular to a three-layer sealing wiring structure. Background technique [0002] With the gradual improvement of people's quality of life, more and more junction boxes are used. Junction boxes are used in the joints of wires (such as relatively long lines, or corners of wire tubes, or connections with circuit components and modules). As a transition, the wire is connected to the junction box to connect the circuit in the junction box to protect the wire and connect the wire. However, at present, the part where the wire is in contact with the junction box does not have a good sealing structure. At the same time, the outer insulator of the wire is inevitably worn out after long-term use, so that water or moisture often seeps into the inside of the wire along the surface of the wire, affecting the insulation effect, and even causing a short circuit fault. Contents of the invention [0003] In...
