[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-4As shown, this utility model provides a technical solution: a waterproof and dustproof sealing protective sleeve for automotive wiring harness connectors, including a first protective sleeve 1, a second protective sleeve 2 installed on the top of the first protective sleeve 1, a connector body 17 placed inside the first protective sleeve 1, first hollow blocks 3 fixedly connected to both sides of the first protective sleeve 1, and slots 4 opened at both ends of the inner cavity of the first hollow block 3; second hollow blocks 5 fixedly connected to both sides of the second protective sleeve 2; multiple wire-passing holes 6 opened at one end of both the first protective sleeve 1 and the second protective sleeve 2; and adjustment holes 7 opened at both ends of the second hollow blocks 5. An adjusting rod 8 is slidably connected inside the connector body 7. One end of the adjusting rod 8 is fixedly connected to a connecting plate 9, and one end of the connecting plate 9 is fixedly connected to a locking block 10. The operator places the connector body 17 into the inside of the first protective sleeve 1, then engages the second protective sleeve 2 with the first protective sleeve 1, and then moves the adjusting rod 8 to drive the connecting plate 9 to insert the locking block 10 into the slot 4, thus fixing the first protective sleeve 1 and the second protective sleeve 2. This allows the first protective sleeve 1 and the second protective sleeve 2 to wrap the connector body 17, thereby achieving a waterproof and dustproof sealing effect.

[0022] Reference Figure 4 As shown in this embodiment: both sides of the inner cavity of the second hollow block 5 are provided with sliding grooves 11, and both sides of the connecting plate 9 are fixedly connected with sliders 12. The surface of the sliders 12 is slidably connected to the inside of the sliding grooves 11. By setting the sliding grooves 11 and sliders 12, when the operator moves the connecting plate 9, the connecting plate 9 drives the sliders 12 to slide inside the sliding grooves 11. The sliding grooves 11 limit the sliders 12, and the sliders 12 limit the connecting plate 9, thereby making the connecting plate 9 more stable when moving.

[0023] Reference Figure 4 As shown in this embodiment: a reset spring 13 is fixedly connected to one end of the connecting plate 9, and one end of the reset spring 13 is fixedly connected to the inside of the second hollow block 5. By setting the reset spring 13, the adjusting rod 8 can automatically reset when it is not under force, thereby allowing the card block 10 to be quickly inserted into the card slot 4, which makes it convenient for the staff to install and fix the second protective sleeve 2.

[0024] Reference Figure 2 and Figure 4 As shown in this embodiment, the external shape of the card block 10 matches the internal shape of the card slot 4. By setting the external shape of the card block 10 to match the internal shape of the card slot 4, when the card block 10 is fully inserted into the card slot 4, the card block 10 and the card slot 4 fit tightly together, thereby improving the stability of the second protective sleeve 2 after installation and preventing the second protective sleeve 2 from shaking or falling off.

[0025] Reference Figure 2 and Figure 3As shown in this embodiment: the top of the first protective sleeve 1 is provided with a positioning groove 14, and the bottom of the second protective sleeve 2 is fixedly connected with a positioning block 15. The surface of the positioning block 15 is slidably connected to the inside of the positioning groove 14. By setting the positioning groove 14 and the positioning block 15, when the second protective sleeve 2 needs to be installed, the positioning block 15 is aligned with the positioning groove 14 and inserted. The positioning block 15 slides inside the positioning groove 14 until the positioning block 15 is completely inside the positioning groove 14. At this time, the second protective sleeve 2 and the first protective sleeve 1 are initially connected. By setting the positioning groove 14 and the positioning block 15, the second protective sleeve 2 can be initially positioned, making the installation of the second protective sleeve 2 more convenient and quick, and improving the stability of the second protective sleeve 2 after installation.

[0026] Reference Figure 5 As shown in this embodiment: a first sealing gasket 16 is fixedly connected to the inner wall of the wire hole 6; an interface groove 18 is provided at the other end of both the first protective sleeve 1 and the second protective sleeve 2; and a second sealing gasket 19 is fixedly connected to the other end of both the first protective sleeve 1 and the second protective sleeve 2. By setting the first sealing gasket 16, the sealing performance of the inner wall of the wire hole 6 can be improved, preventing moisture and dust from entering the interior of the protective sleeve through the wire hole 6 and damaging the connector body 17. At the same time, by setting the interface groove 18 and the second sealing gasket 19, when it is necessary to connect other wire harness connectors to this utility model, other wire harness connectors can be inserted into the interior of the interface groove 18. At this time, the second sealing gasket 19 seals the connection between the other wire harness connectors and the interface groove 18, thereby further improving the overall sealing performance.

[0027] Working principle: The operator places the connector body 17 inside the first protective sleeve 1, then engages the second protective sleeve 2 with the first protective sleeve 1. Next, by moving the adjusting rod 8, the connecting plate 9 is moved to insert the locking block 10 into the slot 4, thus fixing the first protective sleeve 1 and the second protective sleeve 2. This allows the first and second protective sleeves 1 and 2 to enclose the connector body 17, achieving a waterproof and dustproof seal. By using the sliding groove 11 and the slider 12, when the operator moves the connecting plate 9, the connecting plate 9 moves the slider 10. 2. The sliding rod 8 slides inside the slide groove 11, which limits the slider 12. The slider 12 limits the connecting plate 9, making the connecting plate 9 more stable during movement. The reset spring 13 allows the adjusting rod 8 to automatically reset when no force is applied, thus allowing the locking block 10 to quickly insert into the slot 4, facilitating the installation and fixing of the second protective sleeve 2. By setting the external shape of the locking block 10 to match the internal shape of the slot 4, when the locking block 10 is fully inserted into the slot 4, the locking block 10 and the slot 4 fit tightly, thereby improving the second protection. To ensure the stability of the second protective sleeve 2 after installation and prevent it from shaking or falling off, a positioning groove 14 and a positioning block 15 are provided. When the second protective sleeve 2 needs to be installed, the positioning block 15 is aligned with the positioning groove 14 and inserted. The positioning block 15 slides inside the positioning groove 14 until it is fully inserted. At this point, the second protective sleeve 2 and the first protective sleeve 1 are initially connected. The positioning groove 14 and the positioning block 15 enable the initial positioning of the second protective sleeve 2, making its installation more convenient and quick. Meanwhile, the stability of the second protective sleeve 2 after installation is improved. By setting the first sealing gasket 16, the sealing performance of the inner wall of the wire hole 6 can be improved, preventing moisture and dust from entering the interior of the protective sleeve through the wire hole 6 and causing damage to the connector body 17. At the same time, by setting the interface groove 18 and the second sealing gasket 19, when it is necessary to connect other wire harness connectors to this utility model, other wire harness connectors can be inserted into the interior of the interface groove 18. At this time, the second sealing gasket 19 seals the connection between the other wire harness connectors and the interface groove 18, thereby further improving the overall sealing performance.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
