Background
Existing marine cable communications typically use separate cables or hydraulic hoses to transmit power or hydraulic power, which can be cumbersome to arrange and potentially risky when there are too many cables or hoses, and thus composite umbilical cables have been developed that integrate multiple cables or hoses, such as umbilicals for use in marine drilling platforms, to transmit power, signals and hydraulic fluid from an auxiliary vessel to the drilling platform. However, due to the harsh environment of the ocean and the weight and length of the umbilical or cable, the umbilical or cable and its end fittings are often damaged in conventional installations.

Not only is durable enough to withstand harsh environments and operating conditions, but also remains flexible enough to accommodate repetitive and periodic movements associated with marine drilling platforms and pipeline handling equipment.
The invention adopts the following technical scheme:
a submarine cable terminal joint comprises an outer sleeve, a joint, a pipe cable bundle consisting of cables or hoses and a potting material, wherein the pipe cable bundle consisting of the cables or the hoses is arranged in the outer sleeve with the joint to form an annular space, the outer sleeve is filled with the potting material and is solidified into a unified whole, the joint consists of a sleeve, a core pipe and a flange, the sleeve, the core pipe and the flange are sequentially connected, and the outer sleeve is inserted into the annular space formed between the sleeve and the core pipe.
Preferably, the flange is a threaded flange and is in threaded connection with the core pipe, and the sleeve is in threaded connection with the core pipe to form an annular space.
Preferably, the outer surface of the core tube is provided with a multi-ring buckling structure with a sawtooth-shaped cross section, the inner surface of the sleeve is provided with a corresponding multi-ring buckling structure with a sawtooth-shaped cross section, the outer diameter of the core tube is matched with the inner diameter of the outer sleeve, and the inner diameter of the sleeve is matched with the outer diameter of the outer sleeve.
Preferably, the outer sleeve material is styrene butadiene rubber.
Preferably, the sleeve, core tube and flange material is stainless steel 316L.
Preferably, the tube bundle is made up of several cables or hoses that are bundled together by spirally winding tape around the cables or hoses.
Preferably, the potting material forms a polyurethane elastomer after filling and curing. The polyurethane elastomer is resistant to petroleum and ozone, and has excellent abrasion resistance.
Preferably, the tube bundle length is greater than the outer jacket tube.
Preferably, the outer diameter of the core pipe is in interference fit with the inner diameter of the outer sleeve, and the inner diameter of the sleeve is in interference fit with the outer diameter of the outer sleeve.
The invention has the beneficial effects that: the present invention utilizes the pipe assemblies such as flanges, sleeves, core tubes, outer sleeves and potting materials to uniformly support and protect the internal pipe cable bundle. This has a number of distinct advantages over existing umbilical solutions: 1) the tube and cable bundle accommodated in the invention can not bear tensile load; 2) the flanges used at both ends of the present invention make the operation, installation and replacement/maintenance easier and faster, 3) the present invention can protect the inner tube and cable bundle from wear, harsh environments and mechanical damage.
