Description

Technical Field

[0001] The utility model relates to the technical field of data cables, and particularly relates to an epoxy resin data cable. Background Art

[0002] Today, with the continuous development of electronic technology, various electronic products emerge in an endless stream. Most electronic devices are inseparable from data transmission, which requires the use of data cables for data transmission and power transmission. Existing data cables have the following defects when in use: First, for underwater operation equipment, the position change of the data cable caused by buoyancy will lead to unstable or attenuated signal transmission. Therefore, data cables with buoyancy meeting the requirements need to be designed for different underwater environments. The outer sheath of existing data cables generally uses synthetic rubber, and a sheath of foam material is added to it to change the buoyancy of the data cable. However, the foam material is not processable and has water absorption. After absorbing water, its shape will change, resulting in a large change in buoyancy. Second, the power core wire will generate a lot of heat during operation, but existing data cables cannot quickly dissipate heat from the power core wire, resulting in the materials around the power core wire always being in a high-temperature environment. Therefore, the aging of the materials will be accelerated. Content of the Utility Model

[0003] The purpose of the utility model is to provide an epoxy resin data cable to solve the problems mentioned in the above background art.

[0004] To solve the above technical problems, the utility model provides the following technical solution: An epoxy resin data cable includes a first pipe. A connection block is fixedly connected to the first pipe, and a second pipe is fixedly connected to the connection block and sleeved inside the first pipe. A first shielding sleeve is arranged on one side of the second pipe, and a second shielding sleeve is arranged on the other side. The second shielding sleeve is sleeved with an inner sheath, and the first shielding sleeve is sleeved inside the inner sheath. An outer sheath is fixedly connected to the inner sheath. Second hemispherical grooves are formed on the inner wall of the outer sheath, and first hemispherical grooves are formed at positions corresponding to the second hemispherical grooves on the outer wall of the inner sheath. Helium is arranged in the first pipe, the first hemispherical grooves and the second hemispherical grooves. A power core wire is installed in the first shielding sleeve, a ground wire and two data transmission core wires are installed in the second shielding sleeve, and protective sleeves are arranged on the power core wire, the ground wire and the two data transmission core wires.

[0005] Preferably, partition blocks are fixedly connected to both outer walls on both sides of the second pipe, and the two partition blocks are respectively arranged on both sides of the first shielding sleeve.

[0006] Preferably, grooves are formed on both of the two partition blocks, and a plurality of first through holes are uniformly distributed in the grooves and are conductively connected to the inside of the second pipe.

[0007] Preferably, a plurality of second through holes are evenly distributed at positions corresponding to the grooves on the inner sheath, and third through holes are formed at positions corresponding to the second through holes on the outer sheath.

[0008] Preferably, flame-retardant foam particles are provided inside both the first shielding sleeve and the second shielding sleeve.

[0009] An epoxy resin data cable provided by the present utility model has the following advantages: The present utility model uses low-density epoxy resin to make the outer sheath and the inner sheath. By controlling the number of hemispherical grooves and the amount of helium gas filled in the inner and outer sheaths, the buoyancy of the data cable can be controlled, enabling it to face a more complex underwater environment; by adding a second pipe and a partition block outside the power core wire, the heat dissipation efficiency of the power core wire is improved by using water flow, thereby avoiding the accelerated aging of the data cable due to being in a high-temperature environment for a long time.
