AI Technical Summary
Existing waterproof connectors are prone to sealing performance degradation in complex environments due to material aging, assembly deviations, or external impacts. They are difficult to withstand high-pressure sprays and deep immersion, and the transition between cables and connectors is not adequately protected, making them susceptible to moisture intrusion and equipment damage.
The system employs a multi-layered protective structure, including an outer shell protective assembly and a sealing and clamping waterproof assembly. The outer shell protective assembly forms the first layer of protection through the snap-fit between the female and male protective shells. The sealing and clamping waterproof assembly achieves the second layer of sealing through the cooperation of the waterproof clamping stud and the clamping slider. The self-locking assembly prevents the clamping stud from loosening, thus forming a multi-layered protective barrier.
It significantly improves the waterproof performance and reliability of connectors, extends equipment life, reduces safety hazards, and can effectively resist moisture intrusion in complex environments.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof cable connector technology, specifically a multi-layered waterproof cable connector. Background Technology
[0002] In the field of electrical connections, waterproof cable connectors are core components that ensure the stable operation of equipment in complex environments. They are widely used in outdoor engineering, rail transit, new energy equipment and other scenarios. In these scenarios, connectors need to withstand multiple tests such as rain immersion, moisture erosion, dust pollution and mechanical vibration. Once the waterproofing fails, it can easily cause short circuits, signal interruptions or even equipment damage, and in severe cases, it may lead to safety accidents.
[0003] Existing waterproof connectors mostly rely on a single sealing structure, such as an interference fit of a rubber ring or sealant filling. In long-term use, such designs are prone to sealing performance degradation due to material aging, assembly deviations, or external impacts, making them unsuitable for harsh environments such as high-pressure spraying and deep immersion. At the same time, traditional products do not provide sufficient protection for the transition area between the cable and the connector. Under frequent bending or pulling, the waterproof structure is easily damaged, leading to moisture intrusion. Therefore, the development of a multi-layered waterproof cable connector that can adapt to complex working conditions has become an urgent need to improve the reliability of electrical systems. To this end, we have proposed a multi-layered waterproof cable connector. Utility Model Content

Working principle: When using this utility model, firstly, align the male connector 16 with the interface of the female connector 10 to complete the initial insertion. The female connector snap-fit spring 4 on the side of the female connector protective shell 2 and the male connector snap-fit boss 5 on the side of the male connector protective shell 3 engage with each other, making the two protective shells tightly connected, forming the first physical barrier, effectively preventing external impacts, dust and a small amount of splashed water from directly invading the connector. At the same time, rotate the waterproof clamping studs 6 in the rotation support holes 9 on the top and bottom surfaces of the female connector protective shell 2. The waterproof clamping studs 6 and the threaded holes 13 on the top of the waterproof clamping slider 12 form a threaded drive, driving the waterproof clamping slider 12 to move inward along the sliding guide boss on the inner side of the female connector protective shell 2. This causes the sealing waterproof sleeve 14 inside the clamping waterproof slider 12 to fit tightly against the connection between the male connector 16 and the female connector 10. Through interference fit, a second sealing line is formed, which can resist the intrusion of water vapor in harsh environments such as high-pressure spraying and deep immersion. When the waterproof clamping stud 6 rotates, the self-locking grooves 15 distributed at equal intervals on its outer ring rotate together. When the sealing waterproof sleeve 14 reaches the preset clamping force, the self-locking spring 11 on the side of the self-locking support platform 17 pushes the self-locking slider 7 to slide into the corresponding self-locking groove 15 along the self-locking sliding hole 8. The reverse rotation of the waterproof clamping stud 6 is restricted by mechanical locking, which avoids the clamping loosening caused by external forces such as vibration and impact, and ensures that the sealing performance is durable and reliable.
