[0025] Example

[0026] In the Chinese patent with authorization publication number CN221102559U, the existing device is a modular splicing structure and is fixed with fasteners such as screws. This fixing method requires workers to spend more time rotating multiple sets of screws during the installation process, thereby reducing installation efficiency.

[0027] See also Figure 1-5The utility model provides a technical solution: a quick-connect cable connector joint, comprising a connector shell 1 that can be used for a cable connector, a limit plate 2 symmetrically nested and fixed on the surface of the connector shell 1, a heat shrink tube 3 nested on the surface of the connector shell 1, and a sealing component 4 provided on the surface of the connector shell 1. In order to improve the installation speed of the device, a fixing structure 5 is provided on the surface of the sealing component 4, the fixing structure 5 includes a bottom plate 501 and a plastic clip 502, the bottom plate 501 is attached to the surface of the connector shell 1, the plastic clip 502 is symmetrically fixed to the surface of the bottom plate 501, the plastic clip 502 and the sealing component 4 are connected to each other, and a positioning component 6 is provided on the surface of the plastic clip 502. In order to waterproof the docked cables, two heat shrink tubes 3 are provided, and the two heat shrink tubes 3 are symmetrically distributed about the longitudinal center axis of the connector shell 1. In order to facilitate the observation of whether the cables are successfully docked, a sealing component 4 is provided. The sealing component 4 includes a side plate 401 and a cover plate 402. The side plate 401 is attached to the surface of the connector shell 1, and the cover plate 402 is fixed to the surface of the side plate 401.

[0028] In order to fix and limit the docking cables, the surface of the cover plate 402 is threadedly connected with a fastening bolt, and the two fastening bolts are symmetrically distributed about the longitudinal center axis of the cover plate 402. In order to facilitate the fixation of the connector shell 1 and the cover plate 402, the end of the plastic clip 502 is a trapezoidal structure, and the plastic clip 502 is engaged with the side plate 401. In order to avoid offset between the plastic clips 502, so that the connector shell 1 and the cover plate 402 are disengaged, a positioning component 6 is provided, and the positioning component 6 includes a rubber block 601 and a grab hole 602. The rubber block 601 is clamped between the plastic clips 502, and the grab hole 602 is opened on the surface of the rubber block 601. The surface of the rubber block 601 is designed with a rough part. Four groups of positioning components 6 are provided, and the four groups of positioning components 6 are symmetrically distributed about the longitudinal center axis of the connector shell 1.

[0029] Working principle or structural principle, first, after the staff completes the cable docking, they pass the cables through the inside of the heat shrink tube 3 respectively, so that the docking point of the two cable sections is located inside the connector shell 1. After the staff observes that the cables are successfully docked, they can cover the surface of the connector shell 1 with the cover plate 402, and then take out the bottom plate 501 and make it pass through the connector shell 1 and the side plate 401. During the penetration process, the plastic card strip 502 will be squeezed by the connector shell 1 and the side plate 401 due to its own elastic deformation principle, and deflected in the center. When the trapezoidal part of the plastic card strip 502 is completed, it will reset, thereby completing the splicing and fixation of the connector shell 1 and the cover plate 402. Next, press the rubber block 601 in the middle of the plastic card strip 502, then rotate the fastening bolt to press and fix the cable. Finally, use a hot air gun to spray the heat shrink tube 3. After being heated, the heat shrink tube 3 will shrink rapidly, thereby fitting tightly with the cable to achieve the purpose of sealing.

[0030] Later, the staff can replace the heat shrink tube 3. During the replacement process, the old heat shrink tube 3 can be peeled off and the new one can be re-sleeved on the surface of the joint shell 1 so that its end is in contact with the limit plate 2.

[0031] In summary, the device has the advantages of good sealing and quick installation.
