Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency watertight cable connection, in particular to an underwater sealing device for radio frequency watertight cable connection. Background Art

[0002] RF watertight cable, also known as RF coaxial watertight cable, is mainly used in underwater integrated communication systems and electronic devices of similar technologies, as well as used as internal feeders for high-frequency, high-voltage, and high-power instruments to achieve RF signal transmission. The product adopts a coaxial structure and has the characteristics of high power, low attenuation, good flexibility, reliable watertightness, and resistance to seawater corrosion. When laying RF watertight cable underwater, due to the long laying distance, the length of the RF watertight cable will be less than the laying length. At this time, it is necessary to connect it under the water surface to increase its laying length. In addition, due to the complex underwater conditions, anchored ships, trawling fishing boats and ships passing by will accidentally touch the cable, and large fish will also damage the cable casing, causing damage to the RF watertight cable. This puts higher waterproof requirements on the underwater connection device, and it is necessary to ensure the watertightness of the connection device to prevent water from entering the connection position, thereby affecting information transmission.

[0003] Therefore, it is necessary to propose a technology to improve the above defects. Utility Model Content
