Problems solved by technology

[0002] Existing cables have too few functions, and their structure and appearance are characterized by "silly, big, black, thick, and hard", and they do not have the functions of high temperature resistance, low temperature resistance, and radiation resistance to adapt to the space environment, so they cannot adapt to manned space. Aerospace Engineering Astronauts use for extravehicular activities in space

Embodiment Construction

[0030] As shown in the accompanying drawings, the working principle of the umbilical cable of the present invention is: the cable is tied to the navel of the astronaut, and it is used to ensure the normal work of the astronaut in the cabin of the spacecraft and the activities of going out of space and returning safely in the manned spaceflight project. The cable is also known as a "lifeline" for astronauts when they go out of space. Its functions and functions are: one is to provide life support for astronauts, and the oxygen and pressure required by astronauts inside and outside the spacecraft cabin , power supply and communication are all provided by the spacecraft through this cable; at the same time, the cable also transmits the physiological characteristics of the astronauts outside the spacecraft, such as heart rate, blood pressure, breathing conditions, etc. The physical condition in space; the second is to play a role of control and insurance to prevent accidents caused...

Abstract

The invention relates to an umbilical cable which adopts a central force bearing layer comprising a steel wire and a nylon rope, wherein an insulated core layer A, an insulated core layer B, an insulated core layer C, an insulated core layer D and a nylon braided sleeving are sequentially wound outside the central force bearing layer, wherein the insulated core layer A, the insulated core layer B, the insulated core layer C and the insulated core layer D have different specifications, numbers and winding directions of leads; the nylon braided sleeving is arranged outside the insulated core layer D; the lead comprises a conductor; an insulating layer is wound outside the conductor; and a shield is woven outside a sintered wire core. The invention overcomes the defects that the functions ofthe current cables can not meet the space environmental requirements, and the structure and appearance are ugly, big, black, thick and hard; and the umbilical cable is suitable to be used as a cable used in the space environment, especially suitable to be used as a cable for extravehicular activities in the space for astronauts of manned spaceflight engineering.

Description

technical field [0001] The invention relates to an umbilical cable, in particular to a special shielded flexible umbilical cable for astronauts in aerospace engineering. Background technique [0002] Existing cables have too few functions, and their structure and appearance are characterized by "stupid, big, black, thick, and hard", and they do not have functions such as high temperature resistance, low temperature resistance, and radiation resistance to adapt to the space environment, so they cannot adapt to manned space. Aerospace Engineering Astronauts are used for extravehicular activities in space. Contents of the invention [0003] In view of the above situation, the purpose of the present invention is to provide a kind of not only has good electrical conductivity, but also has excellent tensile properties and softness, and compact structure, reasonable design, reliable use, does not need to invest in new production equipment and The production process is improved, ...
