Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings:

[0017] like Figure 1As shown, a waterproof cable connector device includes a first cable 1 and a second cable 2, which are connected by a connector 3. The connector 3 can be a conventional cable connector, such as a quick-connect male-female connector. A protective sleeve 4 is fitted onto the connector 3, and the ends of the first cable 1 and the second cable 2 are located inside the protective sleeve 4. The protective sleeve 4 waterproofs the connector 3, preventing water from entering. Specifically, one end of the protective sleeve 4 has a first sealing end plate 5 with a first through hole 6. The first cable 1 passes through the first through hole 6. To prevent water from flowing into the protective sleeve 4 through the gap between the first through hole 6 and the first cable 1, a first rubber sealing ring 7 is fitted onto the first cable 1 and fixed to it. The first rubber sealing ring 7 abuts against the inner side of the first through hole 6, sealing the gap between the first through hole 6 and the first cable 1. The outer diameter of the first rubber sealing ring 7 is larger than the diameter of the first through hole 6. A first chamfer 8 is provided on the side of the first rubber sealing ring 7 near the first through hole 6. The first chamfer 8 allows the first rubber sealing ring 7 and the first through hole 6 to fit more tightly, improving the sealing effect.

[0018] A sealing tube 9 is detachably connected to the end of the protective sleeve 4 away from the sealing end plate 5. The diameter of the sealing tube 9 is the same as that of the protective sleeve 4. A second sealing end plate 10 is provided at the end of the sealing tube 9 away from the protective sleeve 4. The second sealing end plate 10 has a second through hole 11, through which the second cable 2 passes. Specifically, a connecting screw 12 is provided between the protective sleeve 4 and the sealing tube 6, connecting the sealing tube 9 and the protective sleeve 4. A wire-passing hole 13 is provided in the connecting screw 12 along the axial direction of the connecting screw 12, through which the second cable 2 passes. The end of the protective sleeve 4 away from the sealing end plate 5 is detachably connected to the sealing end plate 5. The end of the first sealing end plate 5 is provided with a first internal thread 14, and the end of the sealing tube 9 away from the second sealing end plate 10 is provided with a second internal thread 15. The two ends of the connecting screw 12 are respectively installed on the first internal thread 14 and the second internal thread 15. During installation, only the connecting screw 12 needs to be rotated. By rotating the connecting screw 12, the protective sleeve 4 and the sealing tube 9 are connected. In order to facilitate the rotation of the connecting screw 12, a grip section 16 for rotating the connecting screw 12 is formed in the middle of the connecting screw 12. The grip section 16 is a circular structure with a diameter larger than that of the connecting screw 12. The grip section 16 makes it easy to rotate the connecting screw 12.

[0019] Similarly, to prevent the gap between the second through hole 11 and the second cable 2 from flowing into the sealing tube 9 and the protective sleeve 4, a second rubber sealing ring 17 is fitted on the second cable 2. The second rubber sealing ring 17 is also fixed on the second cable 2 and abuts against the inner side of the second through hole 11. In addition, the outer diameter of the second rubber sealing ring 17 is larger than the diameter of the second through hole 11. The second rubber sealing ring 17 has a second chamfer 18 on the side near the second through hole 11. The first chamfer 8 and the second chamfer 18 can make the sealing of the first rubber sealing ring 7 and the second rubber sealing ring 17 more tight.

[0020] The method of using this utility model is as follows:

[0021] Before installing the cable connector, first install the first rubber sealing ring 7 and protective sleeve 4 on the first cable 1, and simultaneously install the second rubber sealing ring 17 and sealing tube 9 on the second cable 2. Then install the connector 3 on the cables. When using this device, first sleeve the connecting screw 12 onto the second cable 2, then connect the first cable 1 and the second cable 2 through the connector 3. Align the two ends of the connecting screw 12 with the first internal thread 14 of the protective sleeve 4 and the second internal thread 15 of the sealing tube 9, respectively. Then, hold the first sealing end plate 5 and the second sealing end plate 10 with one hand, and rotate the connecting screw 12 by rotating the grip section 16 with the other hand, so that... The two ends of the connecting screw 12 are respectively inserted into the first internal thread 14 and the second internal thread 15. During this process, the protective sleeve 4 and the sealing tube 9 approach each other. When the first through hole 6 and the second through hole 11 abut against the first rubber sealing ring 7 and the second rubber sealing ring 17 respectively, the installation is completed. By rotating the connecting screw 12, the protective sleeve 4 and the sealing tube 9 can be prevented from rotating relative to the first cable 1 and the second cable 2. This prevents the first sealing end plate 5 and the second sealing end plate 10 from rotating and rubbing relative to the first rubber sealing ring 7 and the second rubber sealing ring 17, effectively preventing wear on the first rubber sealing ring 7 and the second rubber sealing ring 17.

[0022] After installation, this device can form a sealed air-drop and place the connector 3 within the space, effectively preventing rainwater or other water from directly contacting the connector 3, providing good protection. In addition, this device has a simple structure, requires no modification to the plug, and is inexpensive.
