Description

Technical Field

[0001] This utility model relates to the field of communication technology, and more specifically, to a waterproof communication connector. Background Technology

[0002] In the field of communications, connectors are key components for achieving circuit connections and ensuring signal transmission. Their performance directly affects the stable operation of the entire communication system. Ordinary communication connectors can function normally in dry environments, but they exhibit numerous problems when faced with special scenarios such as humidity, water, or even underwater environments. Once moisture seeps into the connector, it can easily cause short circuits, corrosion, and other issues, leading to signal transmission interruptions, data loss, and in severe cases, even damage to communication equipment, resulting in incalculable economic losses and communication failures.

[0003] In existing technologies, traditional connectors have a simple sealing structure, which makes them susceptible to moisture intrusion due to interface gaps, leading to short circuits or signal interruptions. Conventional connectors are also prone to loosening and detachment under vibration or impact, affecting communication reliability. Long-term exposure to humid and corrosive environments can cause the connector surface to wear and age, shortening its service life. Utility Model Content

[0008] The present invention is further configured such that the sealing device includes a sealing sleeve, the sealing sleeve and the fixed sleeve are threadedly connected and the sealing sleeve and the fixed pipe are threadedly connected, and a sealing ring is provided inside the sealing sleeve between the sealing sleeve and the first connector and between the sealing sleeve and the second connector, which facilitates the installation of the sealing sleeve and improves the waterproof sealing between the sealing sleeve and the connector circuit.

[0009] The present invention is further provided with a sealing ring between the outer side of the sealing sleeve and the fixed pipe, and between the outer side of the sealing sleeve and the fixed sleeve, which improves the sealing performance of the connection between the sealing sleeve and the fixed pipe and the fixed sleeve.

[0010] The present invention is further configured such that the fixed tube is provided with a sliding block, and the fixed sleeve is provided with a sliding groove that cooperates with the sliding block, so as to facilitate the positioning and installation of the fixed tube and the fixed sleeve.

The compression sleeve 8 is provided with a snap-fit ​​hole 7 that mates with the snap-fit ​​rod 4. The inclined surface 9 of the fixed sleeve 3 and the fixed tube 5 are coated with a waterproof layer 10 and a wear-resistant layer 11. The fixed tube 5 is provided with a sliding block 15. The fixed sleeve 3 is provided with a sliding groove 16 that cooperates with the sliding block 15. The fixed sleeve 3 is provided with a snap-fit ​​groove 17.

[0030] In this embodiment, communication is established through the first connector 1 and the second connector 2. The extrusion sleeve 8 is moved towards the extrusion ring 20, compressing the extrusion spring 21. At this time, the snap-fit ​​rod 4 extends outward under the elastic force of the snap-fit ​​spring 19, connecting the fixed sleeve 3 and the fixed tube 5 sleeved on the lines of the first connector 1 and the second connector 2. The sliding block 15 and the sliding groove 16 are aligned, and the fixed tube 5 is inserted into the fixed sleeve 3. The sealing gasket 6 of the fixed tube 5 improves the connection sealing between the fixed tube 5 and the fixed sleeve 3. Then, the extrusion sleeve 8 is released. Under the elastic force of the extrusion spring 21, the extrusion sleeve 8 squeezes the snap-fit ​​rod 4 through the inclined surface 9, causing the snap-fit ​​rod 4 to drive the snap-fit ​​plate 18 to squeeze the snap-fit ​​spring 19. At the same time, the snap-fit ​​rod 4 is inserted into the snap-fit ​​hole 7, connecting and fixing the position of the fixed sleeve 3 and the fixed tube 5. This facilitates the external protection of the first connector 1 and the second connector 2, improving the stability of the communication line connection.

[0031] Please see Figures 3-5As one embodiment of the sealing device, waterproof layer 10, and wear-resistant layer 11: the sealing device includes a sealing sleeve 12, with threaded connections between the sealing sleeve 12 and the fixed sleeve 3, and between the sealing sleeve 12 and the fixed pipe 5; a sealing ring 13 is provided inside the sealing sleeve 12 between it and the first connector 1, and inside the sealing sleeve 12 between it and the second connector 2; a sealing ring 14 is provided outside the sealing sleeve 12 between it and the fixed pipe 5, and outside the sealing sleeve 12 between it and the fixed sleeve 3; the waterproof layer 10 includes chloroprene rubber asphalt waterproof layer.

The sealing sleeve 12 is then threaded onto the fixed pipe 5 and the fixed sleeve 3. The sealing sleeve 12 improves the waterproof sealing performance of the connection between the sealing sleeve 12 and the lines. The sealing ring 14 further improves the sealing performance of the connection between the sealing sleeve 12 and the fixed pipe 5 and the fixed sleeve 3. The application of the neoprene rubber asphalt waterproof coating layer 22, the polyurethane waterproof coating layer 23, and the acrylic waterproof coating layer 24 achieves waterproofing, effectively isolating external moisture and greatly improving the sealing performance of the fixed pipe 5 and the fixed sleeve 3. The application of the polyurea coating layer 25, the titanium nitride coating layer 26, and the polyamide coating layer 27 achieves wear resistance, preventing wear on the fixed pipe 5 and the fixed sleeve 3 during use.

[0033] In summary, during use or operation of the overall equipment: communication is established through the first connector 1 and the second connector 2. The extrusion sleeve 8 moves towards the extrusion ring 20, compressing the extrusion spring 21. At this time, the snap-fit ​​rod 4 extends outward under the elastic force of the snap-fit ​​spring 19, connecting the fixed sleeve 3 and the fixed tube 5 fitted on the lines of the first connector 1 and the second connector 2. The sliding block 15 and the sliding groove 16 are aligned, and the fixed tube 5 is inserted into the fixed sleeve 3. The sealing gasket 6 of the fixed tube 5 improves the connection sealing between the fixed tube 5 and the fixed sleeve 3. Then, the extrusion sleeve 8 is released. Under the elastic force of the extrusion spring 21, the extrusion sleeve 8 presses the snap-fit ​​rod 4 through the inclined surface 9, causing the snap-fit ​​rod 4 to drive the snap-fit ​​plate 18 to press the snap-fit ​​spring 19. At the same time, the snap-fit ​​rod 4 extends into the snap-fit ​​hole 7, connecting and fixing the positions of the fixed sleeve 3 and the fixed tube 5. This facilitates the external protection of the first connector 1 and the second connector 2, improving the stability of the communication line connection.
