[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a waterproof and moisture-proof connector includes a tubular assembly 1 with threaded slots 12 at both ends. Wires consisting of inner wires 7 and outer sheaths 71 are inserted into the threaded slots 12. A plug 2 is threadedly rotatably disposed within each threaded slot 12, and the wires are movably disposed within through holes 21 on the plug 2. An air-filled ring 6 disposed within the threaded slot 12 and the plug 2 are pushed against each other to expand and adhere to the outer sheath 71 and the inner wall of the threaded slot 12. By inserting two wires into the threaded slots 12 at both ends of the tubular assembly 1 and passing them through the through holes 21 on the plug 2, and then making the inner wires 7 of the two wires contact to achieve electrical connection, the plug 2 is threadedly rotated within the threaded slot 12, causing the plug 2 to push the air-filled ring 6 to expand and adhere to the outer sheath 71 and the inner wall of the threaded slot 12, thereby sealing the exposed ends of the wires.

[0026] As a further technical solution provided by this utility model, conductive plates 4 are fixedly installed in the two threaded slots 12 respectively, and the cones 41 provided on the two conductive plates 4 fit together, with the inner wire 7 movably disposed in the cones 41.

[0027] Specifically, such as Figure 2 As shown, when the inner wire 7 on the conductor is inserted into the cone 41, the cones 41 on the two conductive plates 4 are in contact with each other, so that the two conductors are electrically connected through the two conductive plates 4, and the cones 41 limit the position of the inner wire 7.

[0028] Furthermore, multiple elastic patches 42 arranged in a circular array are fixedly installed on the conductive plate 4, and the elastic patches 42 are respectively movably disposed on the inner line 7.

[0029] Specifically, when the inner wire 7 of the conductor passes through the space between multiple elastic patches 42, and then the end of the inner wire 7 is inserted into the cone 41, the elastic patches 42 deform and contact the outer wall of the inner wire 7 respectively, thereby using the elastic patches 42 to enhance the contact area between the inner wire 7 and the conductive plate 4 and enhance conductivity.

[0030] Furthermore, a limiting ring 5 is provided inside the threaded groove 12. When the plug 2 pushes the airbag ring 6 to expand, the airbag ring 6 is respectively attached to the elastic patch 42 and the outer skin 71.

[0031] Specifically, the limiting ring 5 supports the airbag ring 6, and when the plug 2 pushes the airbag ring 6 to inflate, at this time... Figure 4 As shown, the airbag ring 6 is attached to the outer wall of the outer sheath 71 and the inner wall of the threaded groove 12 to seal the wire. At the same time, the airbag ring 6 expands to squeeze and push multiple elastic patches 42 to deform and bend towards the inner wire 7. At this time, the multiple elastic patches 42 deform to attach to the outer wall of the inner wire 7, thereby enhancing the conductivity between the inner wire 7 and the conductive plate 4.

[0032] Furthermore, the outer wall of the plug 2 is hinged with a pressure rod 3, and the outer walls of the tube assembly 1 at both ends are respectively provided with positioning grooves 11 arranged in a circular array, and the pressure rod 3 is movably disposed in the positioning grooves 11.

[0033] Specifically, when the plug 2 rotates on the inner wall of the threaded groove 12, the plug 2 compresses the airbag ring 6 to expand. When the airbag ring 6 expands to a certain extent, the position of the plug 2 is controlled so that the pressure rod 3 matches the nearest positioning groove 11. Then the pressure rod 3 is flipped so that it is embedded in the positioning groove 11. The pressure rod 3 is then used to lock the plug 2 relative to the tube assembly 1 by being located in the positioning groove 11, thereby avoiding the loosening problem caused by the rotation of the plug 2.

[0034] Furthermore, a squeezing rod 23 is slidably disposed inside the plug 2, and the squeezing rod 23 is movably disposed on the outer skin 71.

[0035] Specifically, the outer sheath 71 is pushed by the extrusion rod 23 slidably disposed inside the plug 2, thereby causing the wire to be clamped and fixed by the inner wall of the perforation 21 and the extrusion rod 23 to a certain extent.

[0036] Furthermore, a rubber pad 24 is fixedly installed at one end of the extrusion rod 23 relative to the outer skin 71, and the pressure block 32 provided on the pressure rod 3 is inserted into the rubber pad 24.

[0037] Specifically, when the pressure rod 3 is embedded in the positioning groove 11, the pressure rod 3 flips down to press down the extrusion rod 23, so that the extrusion rod 23 squeezes the outer sheath 71, thereby fixing the wire to a certain extent.

[0038] Furthermore, the guide hole 31 on the pressure rod 3 corresponds to the threaded hole 22 on the plug 2.

[0039] Specifically, the bolt passes through the guide hole 31 and rotates into the threaded hole 22, thereby using the bolt to install and fix the pressure rod 3, and the pressure rod 3 continuously presses the extrusion rod 23 to make the wire stably located in the threaded groove 12.

[0040] Furthermore, the elastic patch 42 is made of elastic stainless steel sheet.

[0041] Furthermore, the airbag ring 6 is made of high-temperature resistant rubber.

[0042] Working principle: By inserting two wires into the threaded slots 12 at both ends of the tube assembly 1 and passing them through the through holes 21 on the plug 2, and then inserting the inner wire 7 of the wire into the cone 41, the cones 41 on the two conductive plates 4 are in contact with each other, so that the two wires are electrically connected through the two conductive plates 4. By rotating the plug 2 in the threaded slot 12, the plug 2 pushes the airbag ring 6 to inflate. When the airbag ring 6 inflates, it is like... Figure 4 As shown, the airbag ring 6 is attached to the outer wall of the outer sheath 71 and the inner wall of the threaded groove 12, thereby sealing the wires to prevent short circuits caused by moisture such as rainwater at the wire connection ends. At the same time, the airbag ring 6 expands to push multiple elastic patches 42 to deform and bend towards the inner wire 7. At this time, the multiple elastic patches 42 deform to fit against the outer wall of the inner wire 7, thereby enhancing the conductivity between the inner wire 7 and the conductive plate 4.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
