[0002] With the increasing electrification and intelligence of automobiles, the number of in-vehicle electronic devices is growing exponentially. According to SAE International, the wiring harness length of modern high-end models exceeds 5 kilometers, and the number of connectors exceeds 300 sets. In the harsh operating environment of vehicles (temperature fluctuations of -40℃ to 125℃, vibration acceleration of up to 15G, and wading depth of 500mm), the waterproof performance of connectors directly affects the reliability of the entire vehicle's electrical system. According to the JASO D611 standard, automotive connectors must meet an IP67 or higher protection rating.

[0003] Traditional connectors often use a single rubber plug for waterproofing or a snap-fit ​​fixing structure. During operation, the connector can easily become loose due to vehicle bumps, which can affect the normal operation of the vehicle. Therefore, we propose a waterproof automotive connector terminal for wire harnesses. Summary of the Invention

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 A waterproof automotive connector terminal for wire harnesses includes a first protective mechanism 1, a second protective mechanism 2, a threaded post 3, and a locking mechanism 4. The first protective mechanism 1 is inserted into the interior of the second protective mechanism 2, the threaded post 3 is fixed on the second protective mechanism 2, and the locking mechanism 4 is installed on the first protective mechanism 1. The threaded post 3 is inserted into the interior of the locking mechanism 4, and the first protective mechanism 1 and the second protective mechanism 2 are locked together by the threaded post 3 and the locking mechanism 4.

[0016] In one embodiment, the first protective mechanism 1 includes a first mounting plate 11, a first housing 12 mounted on the side of the first mounting plate 11, a sealing sleeve 13 fixed on the inner wall of the first housing 12, a first cable 14 mounted on the side of the first mounting plate 11, the first cable 14 inserted into the interior of the first housing 12 and connected to a male connector 15, a sealing seat 16 installed between the male connector 15 and the first housing 12, a second protective mechanism 2 installed inside the first housing 12, and a locking mechanism 4 mounted on the first mounting plate 11. The second protective mechanism 2 includes a second mounting plate 21, a second housing 22 mounted on the side of the second mounting plate 21, a second cable 23 mounted on the side of the second mounting plate 21, the second cable 23 inserted into the interior of the second housing 22 and connected to a female connector 24, a threaded post 3 mounted on the side of the second mounting plate 21, and the female connector 24 mounted on the male connector 15. The locking mechanism 4 includes a third housing 41 fixed to the first mounting plate 11, and an adjusting rod 42 mounted on the top of the third housing 41. The adjusting rod 42 is inserted into the interior of the third housing 41 and connected to the first bevel gear 43. The interior of the third housing 41 is rotatably connected to the threaded sleeve 44, which passes through the first mounting plate 11 and is rotatably connected to it. The second bevel gear 45 is fixedly sleeved on the threaded sleeve 44. The first bevel gear 43 and the second bevel gear 45 are meshed and driven, and the threaded column 3 and the threaded sleeve 44 are threaded and driven. By setting a double-layer nested structure of the first and second protective mechanisms, the male and female connection parts are fully sealed and wrapped, achieving the waterproof level requirements. Through the transmission design of the locking mechanism and the threaded column, the threaded sleeve and the threaded column are stably meshed and locked, achieving the effect of vibration resistance and anti-loosening. Through the flexible sealing components of the sealing sleeve and the sealing seat, dynamic waterproof compensation for the cable interface is achieved, improving the reliability of waterproof performance during long-term use. Ultimately, the problems of easy loosening and insufficient waterproof performance of traditional connectors are solved, significantly improving the stability and safety of automotive electrical systems.

[0017] The second housing 22 of the second protective mechanism 2 is inserted into the first housing 22 inside the first protective mechanism 1. The male plug 12 and the female plug 24 are connected. The sealing sleeve 13 and the sealing seat 16 form a primary waterproof barrier. During this process, the adjusting rod 42 of the rotating locking mechanism 4 drives the first bevel gear 43 and the second bevel gear 45 to mesh and drive the threaded sleeve 44 to rotate and engage with the threaded post 3 on the second protective mechanism 2, thereby achieving mechanical locking between the first protective mechanism 1 and the second protective mechanism 2. The double-layer nested structure of the first housing 12 and the second housing 22 forms a physical isolation for the insertion part. Together with the threaded locking force, they resist the intrusion of water vapor and dust, ensuring the long-term stable operation of the connector. In summary, compared with existing technologies, this utility model achieves all-round sealing and wrapping of the male and female connectors through a double-layer nested structure of a first protective mechanism and a second protective mechanism, meeting the waterproof requirements. The locking mechanism and threaded post transmission design achieve stable engagement and locking between the threaded sleeve and the threaded post, achieving vibration resistance and preventing loosening. The flexible sealing components of the sealing sleeve and sealing seat provide dynamic waterproof compensation for the cable interface, improving the reliability of waterproof performance during long-term use. Ultimately, this solves the problems of easy loosening and insufficient waterproof performance of traditional connectors, significantly improving the stability and safety of automotive electrical systems.
