Description

Technical Field

[0001] This utility model relates to the field of electrical connection equipment technology, specifically a 68-pin watertight through-wall socket connector suitable for deep water. Background Technology

[0002] With the advancement of marine resource development and underwater exploration technology, the performance requirements for connectors in underwater equipment are becoming increasingly stringent. Connectors need to ensure a fully stable and secure connection, and even when in contact with small portions of water, they must maintain sufficient sealing. However, traditional watertight connectors have the following problems: Insufficient number of cores: Existing underwater connectors generally have ≤32 cores, which is insufficient to meet the needs of underwater robots, deep-sea sensor arrays at depths of over 500 meters, and other equipment for synchronous transmission of multi-channel signals; Watertightness limitations: Conventional designs achieve simple waterproofing only through a single layer of rubber sealing rings, which can easily lead to water leakage between the joints due to material aging or structural deformation; Furthermore, the existing connectors are prone to detachment or loosening after insertion, resulting in unstable signal connections. When a fault occurs, constant troubleshooting and repair are required, causing inconvenience. Therefore, a device is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a 68-pin watertight wall socket connector suitable for deep water, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a 68-pin watertight wall socket connector suitable for deep water, comprising a connecting end, a first fixed connecting flange, a plug end, a sealing groove, and a sealing ring. The front end of the connecting end is inserted into the end of the plug end, the first fixed connecting flange is fixedly installed on the plug end, the sealing groove is formed at the front end of the plug end, and the sealing ring is uniformly fixedly installed inside the front end of the plug end.

[0005] Preferably, the connecting end includes a second connecting end, a second fixed connecting flange, a fixed connecting threaded post, a first extrusion sealing rubber ring gasket, and a 68-core connecting end. The second fixed connecting flange is fixedly installed on the second connecting end. The fixed connecting threaded posts are evenly distributed on the second fixed connecting flange. The 68-core connecting end is fixedly connected to the inner end of the second connecting end. The first extrusion sealing rubber ring gasket is securely mounted on the 68-core connecting end. Both the plug-in end and the exterior of the second connecting end are fixedly installed with through-wall mounting flanges.

[0006] Preferably, a sliding compression ring is slidably engaged on the 68-core connecting end, and limit mounting rings are fixedly installed on both the sliding compression ring and the second fixed connecting flange. A compression sealing spring is fixedly installed between the limit mounting rings, and a compression sealing rubber ring is fixedly installed on the side of the sliding compression ring away from the compression sealing spring by a fixing bolt.

[0007] Preferably, the extrusion sealing rubber retainer is adapted to the sealing groove.

[0008] Preferably, the 68-pin connector is inserted into the end of the plug-in terminal, and the first extrusion sealing rubber ring gasket is in extrusion contact with the inside of the plug-in terminal.

[0009] Preferably, the fixed connection threaded post is fixed between the second fixed connection flange and the first fixed connection flange by a nut.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs a 68-pin connector, significantly exceeding the capacity limitation of traditional 32-pin underwater connectors. It solves the stringent requirements of complex equipment for synchronous transmission of multi-channel signals. Utilizing triple active sealing protection, it provides ample waterproofing, ensuring safe and stable operation even when exposed to water during professional underwater operations. When the 68-pin connector is inserted into the plug-in end, the first compression sealing rubber ring actively compresses against the inner wall of the plug-in end, forming the first waterproof barrier. The evenly distributed sealing rings at the front end of the plug-in end fit tightly against the outer wall of the inserted 68-pin connector, forming a radial seal around the connector's circumference, preventing water from seeping in through the pin holes. Under the continuous and strong force of the compression sealing spring, the extrusion sealing rubber retainer is firmly embedded in the sealing groove at the front end of the plug end. This design not only fills the end gap between the connection end and the plug end shell, forming a crucial external seal, but its spring pressure characteristics also ensure stable sealing pressure. It can adapt to minor structural changes or vibrations and effectively compensate for the effects of material aging or deformation. Therefore, this device, through its innovative 68-core high-density design, triple sealing structure, and reliable flange mechanical locking mechanism, solves the problems of insufficient core count, poor reliability of single-layer seals, and easy loosening and separation in existing underwater connectors, and is suitable for use in deep water environments of over 500 meters.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 The present invention provides an embodiment of a 68-pin watertight wall socket connector suitable for deep water, comprising a connecting end 1, a first fixed connecting flange 2, a plug end 3, a sealing groove 4, and a sealing ring 5. The front end of the connecting end 1 is inserted into the end of the plug end 3. The first fixed connecting flange 2 is fixedly installed on the plug end 3. The sealing groove 4 is opened at the front end of the plug end 3. The sealing ring 5 is evenly fixedly installed inside the front end of the plug end 3.

[0015] The connecting end 1 includes a second connecting end 6, a second fixed connecting flange 7, a fixed connecting threaded post 8, a first extrusion sealing rubber ring gasket 9, and a 68-core connecting end 10. The second fixed connecting flange 7 is fixedly installed on the second connecting end 6. The fixed connecting threaded posts 8 are evenly distributed on the second fixed connecting flange 7. The 68-core connecting end 10 is fixedly connected to the inner end of the second connecting end 6. The first extrusion sealing rubber ring gasket 9 is secured to the 68-core connecting end 10. The ends of the second connecting end 6 and the plug-in end 3 are respectively connected to wires. The plug-in end 3 and the exterior of the second connecting end 6 are both fixedly installed with through-wall mounting flanges 16. With the help of the threaded holes and screws on the wall panel and the through-wall mounting flanges 16, this device can be easily installed and fixed on the wall for use.

[0016] A sliding compression ring 12 is slidably engaged on the 68-core connecting end 10. Limiting mounting rings 15 are fixedly installed on both the sliding compression ring 12 and the second fixed connecting flange 7. A compression sealing spring 14 is fixedly installed between the limiting mounting rings 15. A compression sealing rubber ring 11 is fixedly installed on the side of the sliding compression ring 12 away from the compression sealing spring 14 by fixing bolts 13. The compression sealing rubber ring 11 is adapted to the sealing groove 4.

[0017] The 68-pin connector 10 is inserted into the end of the plug-in terminal 3. The first compression sealing rubber ring gasket 9 is in compression contact with the inside of the plug-in terminal 3, which fully plays the role of sealing and waterproofing.

[0018] The fixed connection threaded post 8 is fixed between the second fixed connection flange 7 and the first fixed connection flange 2 by a nut, which plays a stabilizing role and prevents the 68-core connection end 10 from loosening or separating from the plug end 3. The diameter of the cable wires connected to the second connection end 6 and the plug end 3 is greater than 30mm.

[0019] Working Principle: During use, the 68-pin connector 10 is inserted into the corresponding insertion hole at the front end of the connector 3. When the 68-pin connector 10 is fully inserted into the connector 3, the first compression sealing rubber ring 9 will compress against the interior of the connector 3, achieving the first layer of sealing protection. Furthermore, when the 68-pin connector 10 is inserted into the connector 3, the sealing rings 5, evenly distributed inside the connector 3, fully contact the outer wall of the 68-pin connector 10, achieving the second layer of sealing protection. After the 68-pin connector 10 is fully inserted into the connector 3, the compression sealing rubber retainer 11 is inserted into the sealing groove 4 and, under the compression of the compression sealing spring 14, is fully distributed inside the sealing groove 4, thus sealing the gap between the outer wall of the 68-pin connector 10 and the connector 3 after insertion. The rubber retaining ring 11 provides a thorough seal, achieving a third layer of sealing protection. Simultaneously, the compression sealing spring 14 compresses the sliding compression ring 12, causing the sliding compression ring 12 to stably and fully compress the sealing rubber retaining ring 11. This ensures the sealing rubber retaining ring 11 is fully positioned inside the sealing groove 4, sealing the end of the insertion end 3. After the 68-core connecting end 10 and the insertion end 3 are precisely and fully inserted, each fixed connecting threaded post 8 is evenly inserted between the second fixed connecting flange 7 and the first fixed connecting flange 2. Nuts are used to fix the fixed connecting threaded posts 8 between the second fixed connecting flange 7 and the first fixed connecting flange 2, allowing the second connecting end 6 and the 68-core connecting end 10 to stably insert with the insertion end 3. This also ensures stable compression deformation of the first compression sealing rubber ring gasket 9 and the compression sealing rubber retaining ring 11, filling the gaps and providing a thorough sealing and waterproofing effect.
