[0030] Please see Figure 1-3 This utility model provides a technical solution: a detachable connector for the conductive tube of a vacuum cleaner, comprising:

[0031] The connector body 1 has an installation port 2 on its outer side wall, and a terminal block 3 is arranged in the installation port 2. The rear end of the connector body 1 extends into a tube 4. A slot 5 is provided on the side of the tube 4, which is inserted into the end of the conductive tube 100. A snap-fit ​​spring piece 120 in the notch 110 on the side of the conductive tube 100 is snapped into the slot 5. A fixing seat 6 is also provided on the side of the tube 4. The fixing seat 6 is inserted into the conductive tube 100. The mounting groove 7 of the fixing seat 6 and the mounting hole 130 of the conductive tube 100 are fixed by radial insertion and screwing fasteners. A first screw seat 8 is also arranged axially on the side of the connector body 1.

[0032] The outer sleeve 9 is fitted onto the connector body 1, and a second screw seat 10 is provided on its inner wall. The first screw seat 8 and the second screw seat 10 are fixed by fasteners.

[0033] The outer surface of the insertion tube 4 extends axially with a guide block 11, which is fitted into the guide opening 140 of the conductive tube 100 to further improve the docking strength between the insertion tube 4 and the conductive tube 100.

[0034] The insertion tube 4 has a first recess 12 on its side, which fits onto a guide plate 150 inside the conductive tube 100. The fixing seat 6 is disposed within the first recess 12. The guide plate 150 has an arched structure. This achieves stable guidance when the insertion tube 4 and the conductive tube 100 are connected, and improves the structural strength of the screw connection between the insertion tube 4 and the conductive tube 100.

[0035] The outer surface of the connector body 1 is also provided with a second recess 13, and the second screw seat 10 is fitted into the second recess 13. This improves the stability of the sliding connection between the insertion tube 4 and the outer sleeve 9.

[0036] The inner wall of the connector body 1 is provided with a limiting rib 14, which axially abuts against the protrusion of the connector body 1. The end of the connector body 1 is provided with a splicing flange 15, which is embedded in the splicing recess 16 at the end of the outer sleeve 9. High-precision positioning is achieved through the splicing and abutting of the inner and outer ends, improving the ease of assembly alignment and assembly strength.

[0037] The assembly process of a detachable connector for a vacuum cleaner's conductive tube in this embodiment includes: firstly, initially fitting the outer sleeve 9 onto the connector body 1, with both aligning with the conductive tube 100, i.e., the outer sleeve 9 is fitted onto it, and the connector body 1 is inserted into it; the first notch 12 slides and aligns with the guide plate 150; then, the snap-fit ​​spring 120 snaps into the snap-fit ​​groove 5, the guide block 11 aligns with the guide opening 140, and the mounting groove 7 aligns with the mounting hole 130, thus completing the initial positioning of the connector body 1 and the conductive tube 100; finally, the connector body 1 is secured... The mounting slot 7 and mounting hole 130 are fixed together; the terminal block 3 is initially positioned inside the mounting opening 2, and the outer sleeve 9 slides along the conductive tube 100 and is sleeved on the connector body 1 to achieve the positioning of the terminal block 3. The second screw seat 10 slides and engages with the second recess 13 until it engages with the first screw seat 8. At this time, the limiting rib 14 abuts against the boss of the connector body 1, and the splicing flange 15 and the splicing recess 16 are spliced ​​together to complete the initial positioning. The two screw seats are fixed by fasteners, thus completing the assembly of the connector.

[0038] In summary, due to the adoption of the above technical solution, the detachable connector for the conductive tube of a vacuum cleaner in this embodiment has the following advantages compared with the prior art:

[0039] This utility model discloses a vacuum cleaner conductive tube connector that connects the connector body, outer sleeve, and conductive tube internally and externally. The connector body and conductive tube are structurally fixed using both snap-fit ​​and screw-fit methods. The outer sleeve is fitted onto the connector body to conceal its surface and the fixing structure to the conductive tube, ensuring aesthetic appeal while preventing accidental unlocking, loosening, or dislodgement of the connector and conductive tube. The assembly and limiting structure ensures a tight fit between the connector body and outer sleeve, facilitating easy operation. The two screw-fit seats are then secured with fasteners, completing the assembly. The connector is easy to assemble and disassemble, facilitating internal wiring and the maintenance and replacement of accessories.
