Description

Technical Field

[0001] This utility model relates to a wire harness connector, and more particularly to a waterproof wire harness connector for use in the field of wire harness technology. Background Technology

[0002] Wire harness connectors are a type of terminal. Connectors, also known as plugs, consist of a plug and a socket, which can be referred to as male and female terminals. In use, the male terminal is inserted into the female terminal to achieve connection. However, in existing wire harness connectors, after the male terminal is inserted into the female terminal, there will inevitably be a gap between the male and female terminals, which can easily allow water or other liquids to enter, posing a safety hazard.

[0003] Chinese patent CN221574421U discloses a wire harness connector. This utility model not only achieves the purpose of spacing and preventing wire harnesses from falling off to ensure the connection and installation effect of the wire harness, but also achieves the purpose of facilitating the disassembly and maintenance of the wire harness connector. Furthermore, it ensures the stability of the wire harness connector during installation and reduces the phenomenon of loosening of the wire harness connector due to external forces after installation.

[0004] However, in some humid, underwater or harsh environments, ordinary wire harness connectors are easily immersed in water, which can lead to problems such as electrical short circuits, signal interference, and corrosion. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that in some humid, underwater or harsh environments, ordinary wire harness connectors are easily immersed in water, which can lead to problems such as electrical short circuits, signal interference, and corrosion.

[0006] To address the aforementioned issues, this utility model provides a waterproof wire harness connector, comprising a connector body with connecting wires, a connector body detachably connected to a connecting device with an interface at the end of the connector body away from the connecting wires, and the connector body engaging with the interface; a protective cover is fitted onto the surface of the connector body, and the protective cover is detachably connected to the connecting device; an adapter is threadedly connected to the end of the protective cover away from the connecting device; a waterproof cover is threadedly connected to the end of the adapter away from the protective cover; a telescopic rod is equidistantly embedded in the inner wall of the waterproof cover; a pressure plate is fixedly connected to the movable end of the telescopic rod; an absorbent sponge is provided on the side of the pressure plate away from the telescopic rod; a rigid sealing ring is fixedly connected to the end of the waterproof cover away from the protective cover; an elastic ring is fixedly connected to the inner wall of the sealing ring; the movable end of the telescopic rod, the pressure plate, and the absorbent sponge are all located inside the waterproof cover; multiple overlapping drainage holes are equidistantly opened on the bottom wall of both the waterproof cover and the adapter; and the elastic ring engages with the surface of the connecting wires.

[0007] In the aforementioned wire harness connector, protective covers and waterproof covers are provided on the surface of the connector body and the connecting wires. When water seeps into the interior through the gaps, it is absorbed by the water-absorbing sponge. Then, the pressure plate is pushed by the telescopic rod to squeeze the water-absorbing sponge and squeeze it out from the drain hole. This keeps the water-absorbing sponge in a water-absorbing state and prevents water from seeping into the protective cover and causing problems such as electrical short circuits, signal interference, and corrosion to the connector body.

[0008] As a further improvement of this application, a threaded groove is provided on the outer ring of the interface on the connecting device, and the protective cover is threadedly connected to the threaded groove.

[0009] As a further improvement of this application, the connecting device is fixedly connected with multiple threaded rings at equal intervals in an annular shape at the outer ring of the threaded groove, and a threaded rod is threadedly connected to the threaded ring through a second nut.

[0010] As a further improvement of this application, a connecting block is fitted on the surface of the adapter, and a through hole corresponding to the threaded ring is opened on the connecting block, and the threaded rod passes through the through hole and positions the connecting block through the first nut.

[0011] As another improvement of this application, an electromagnetic block is installed on the inner wall of the telescopic rod, and the telescopic rod is made of magnetic material.

[0012] As a further improvement to this application, a humidity sensor is fixedly connected inside the adapter, and the detection end of the humidity sensor is in contact with the absorbent sponge.

[0013] As a further improvement to this application, a controller with a control electromagnetic block and a humidity sensor fixedly connected to the connecting device is provided.

[0014] In summary, after inserting the connector body into the interface for positioning, the protective cover is then placed over the connector body, allowing the connecting wires to pass through both the protective cover and the waterproof cover. One end of the protective cover is then inserted into the threaded groove for threaded connection. Even if water splashes onto the surface of the protective cover, it will not seep into the cover. The elastic ring adheres tightly to the surface of the connecting wires due to its elasticity, and a sealing ring at the contact point enhances the waterproof effect. If water seeps into the waterproof cover through gaps in the adapter, it will be absorbed by the absorbent sponge. When the absorbent sponge has a moisture content ≥30%, humidity transfer... The sensor triggers the controller via a wired signal to activate the electromagnetic block, causing the electromagnetic block to repel the magnetic force of the movable end of the telescopic rod. This pushes the movable end of the telescopic rod, causing the pressure plate to move and squeeze the water-absorbing sponge. The water absorbed by the sponge is squeezed out and discharged from the drain hole at the bottom, preventing water from seeping into the protective cover. Furthermore, the adapter is designed with a downward slope from left to right, so if the squeezed water cannot be discharged immediately, it will accumulate on the slope and will not flow back. The adapter is located on the surface of the connecting wire, so even if a small amount of water splashes on the surface, it will not seep into the connector body and cause damage.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figures 1-4A waterproof wire harness connector is shown, comprising a connector body 1 with a connecting wire 2. The connector body 1, at the end away from the connecting wire 2, is detachably connected to a connecting device 3 with an interface 4, and the connector body 1 snaps into the interface 4. A protective cover 6 is fitted onto the surface of the connector body 1, and the protective cover 6 is detachably connected to the connecting device 3. An adapter 7 is threadedly connected to the end of the protective cover 6 away from the connecting device 3, and a waterproof cover 9 is threadedly connected to the end of the adapter 7 away from the protective cover 6. An extension tube is equidistantly embedded in the inner wall of the waterproof cover 9 in an annular shape. The telescopic rod 17 has a pressure plate 10 fixedly connected to its movable end. The pressure plate 10 is provided with a water-absorbing sponge 11 on the side away from the telescopic rod 17. The waterproof cover 9 is fixedly connected to a rigid sealing ring 20 at the end away from the protective cover 6. An elastic ring 12 is fixedly connected to the inner wall of the sealing ring 20. The movable end of the telescopic rod 17, the pressure plate 10, and the water-absorbing sponge 11 are all located inside the waterproof cover 9. The waterproof cover 9 and the bottom wall of the adapter 7 are both provided with multiple overlapping drainage holes 16 at equal intervals. The elastic ring 12 is engaged with the surface of the connecting wire 2.

[0026] The connecting device 3 has a threaded groove 5 on the outer ring of the interface 4, and the protective cover 6 is threadedly connected to the threaded groove 5. An electromagnetic block 18 is installed on the inner wall of the telescopic rod 17. The telescopic rod 17 is made of magnetic material. A humidity sensor is fixedly connected inside the adapter 7, and the detection end of the humidity sensor is in contact with the water-absorbing sponge 11. A controller for controlling the electromagnetic block 18 and the humidity sensor is fixedly connected to the connecting device 3.

[0027] Working principle: After the connector body 1 is inserted into the interface 4 for positioning, the protective cover 6 is then placed on the surface of the connector body 1, allowing the connecting wire 2 to pass through the protective cover 6 and the waterproof cover 9. One end of the protective cover 6 is then inserted into the threaded groove 5 for threaded connection. Even if water splashes onto the surface of the protective cover 6, it will not seep into the protective cover 6. At this time, the elastic ring 12 fits tightly against the surface of the connecting wire 2 through elasticity, and a sealing ring is provided at the contact point to enhance the waterproof effect. If water seeps into the waterproof cover 9 through the gaps in the adapter 7, it will be absorbed by the absorbent sponge 11. When the moisture content of the absorbent sponge 11 is ≥30%, the humidity... The sensor triggers the controller via a wired signal to activate the electromagnetic block 18, causing the electromagnetic block 18 to repel the magnetic force of the movable end of the telescopic rod 17, pushing the movable end of the telescopic rod 17, which in turn moves the pressure plate 10 to squeeze the water-absorbing sponge 11. The water absorbed by the water-absorbing sponge 11 is squeezed out and discharged from the drain hole 16 at the bottom, preventing water from seeping into the protective cover 6. Furthermore, the adapter 7 is designed to slope down from left to right, so if the squeezed water cannot be discharged immediately, it will accumulate on the slope and will not flow back. The adapter 7 is located on the surface of the connecting wire 2, so even if a small amount of water splashes onto the surface, it will not seep into the connector body 1 and cause damage to it.

[0028] By providing a protective cover 6 and a waterproof cover 9 on the surface of the connector body 1 and the connecting wire 2, when water seeps into the interior through the gaps, it is absorbed by the water-absorbing sponge 11. Then, the pressure plate 10 is pushed by the telescopic rod 17 to squeeze the water-absorbing sponge 11, squeezing the water out of the drain hole 16. This keeps the water-absorbing sponge 11 in a water-absorbing state and prevents water from seeping into the protective cover 6 and causing electrical short circuits, signal interference, corrosion and other problems to the connector body 1.

[0029] Second implementation method:

[0030] Figures 5-6 The connecting device 3 is shown to have multiple threaded rings 19 fixedly connected at equal intervals around the outer ring of the threaded groove 5. A threaded rod 13 is threadedly connected to the threaded ring 19 through a second nut 15. A connecting block 8 is fitted on the surface of the adapter 7. The connecting block 8 has a through hole corresponding to the threaded ring 19, and the threaded rod 13 passes through the through hole and is positioned by the first nut 14.

[0031] Working principle: After the protective cover 6 and the adapter 7 are installed on the surface of the connector body 1, the threaded rod 13 is inserted into the corresponding through hole and then engaged with the corresponding threaded ring 19 and fixed by the second nut 15. The other end of the threaded rod 13 is limited by the first nut 14, thereby reinforcing the protective cover 6 and the adapter 7. In dry weather, the first nut 14 and the second nut 15 can be loosened to remove the threaded rod 13 and then the protective cover 6 can be removed from the threaded groove 5. At this time, by adjusting the position of the threaded rod 13, the protective cover 6 and the adapter 7 can be isolated on the surface of the connector body 1, and the connection between the connector body 1 and the interface 4 is in an open state, so as to provide protection without affecting the heat dissipation of the connector body 1 during use.

[0032] The mounting positions of the protective cover 6 and the adapter 7 can be adjusted by means of the threaded rod 13, making them suitable for use in different environments.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
