The coaxial cable comprises a center conducting wire. An insulation porcelain sleeve assembly formed by a plurality of barrel-shaped insulation porcelain sleeves is sleeved on the center conducting wire. The insulation porcelain sleeves in the insulation porcelain sleeve assembly are butted along the middle axis of the center conducting wire in a tail-to-end way. A shielding sleeve is sleeved on the periphery of the insulation porcelain sleeve assembly, and both ends thereof are respectively provided with a sealing porcelain sleeve which is butted with the end surface of the insulation porcelain sleeve assembly, and tightly sleeved onto the sealing porcelain sleeve. Compared with the prior art, the utility model has the advantages of reasonable design, simple structure, easy processing and manufacture, low production cost, stable working performance, especially working in the extreme working environments of high temperature, high voltage and the like, long service life, and wide applicable range.
Description
Technical field
The utility model belongs to the electric parts field, relates to cable, especially relates to a kind of sintered coaxial cable.
Background technology
Coaxial cable is made up of a hollow outside cylinder conductor and an inside conductor that is positioned at central axis, and all separates with insulating material between inside conductor and cylindrical conductor and the cylindrical conductor and the external world.The characteristics of coaxial cable are that antijamming capability is good, the transmission data stabilization, and price is also cheap, is widely used in every field.
In order to improve the performance of coaxial cable, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of coaxial cable [application number: 200680049614.2], it is that insulator layer is set around center conductor, the external conductor layer is set around this insulator layer, the coaxial cable that around this external conductor layer, shell is set and forms, it is characterized in that, described insulator layer is formed by sintering polytetrafluoroethylfilm not, described by insulator layer and described external conductor layer that sintering polytetrafluoroethylfilm does not form between, be provided with and give the shield effectiveness that increased and the metal forming of shape maintains.Therefore, can make and have the fabulous loss that is inserted into, shield effectiveness for the signal leakage that attenuation is increased etc. is also big, keep for the electrical characteristic of high-frequency signal good the time, can carry out bending machining easily and freely with hand under the situation of tool using etc. not, after the bending machining, the shape maintains of its bending machining state is good, by this good shape maintains, can realize being easy to the high-frequency coaxial cable of distribution operation or attended operation etc.
Such scheme has improved the performance of coaxial cable to a certain extent, but still has weak point: manufacturing cost is higher, and course of processing complexity occurs changing because of the material shape change in size causes performance when occurrence temperature changes easily.Service behaviour is stable inadequately, particularly under the environment of HTHP, is difficult to guarantee normal use.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, is easy to processing and manufacturing, the sintered coaxial cable of stable work in work.
For achieving the above object, the utility model has adopted following technical proposal: this sintered coaxial cable, comprise center conductor, it is characterized in that, be arranged with the insulated porcelain sleeve group of forming by the insulated porcelain sleeve of some tubulars on the described center conductor, each insulated porcelain sleeve in this insulated porcelain sleeve group is provided with from beginning to end along the axis of center conductor with leaning, be provided with housing in insulated porcelain sleeve group outer race, be respectively equipped with a sealing insulator that is resisted against insulated porcelain sleeve group end face at the two ends of housing, the end of described housing tightly is enclosed within on the sealing insulator.
Adopt a plurality of insulated porcelain sleeves between center conductor and housing, to form insulating medium layer easily.And, improved service behaviour effectively because pottery has good resistance to elevated temperatures and anti-deformation nature.Assurance the utility model can stably be worked under extreme operational environment such as high temperature, high pressure, and operating pressure can reach 6Mpa, and working temperature reaches 240 ℃.
In above-mentioned sintered coaxial cable, described center conductor is become by silver or copper.Silver or copper have good lead rate, guarantee the service behaviour of coaxial cable.
In above-mentioned sintered coaxial cable, described housing is made by the anaerobic copper material.
In above-mentioned sintered coaxial cable, the internal diameter of described insulated porcelain sleeve and the external diameter of center conductor adapt; The internal diameter of described sealing insulator and the external diameter of center conductor adapt; The external diameter of the internal diameter of described housing and insulated porcelain sleeve and sealing insulator adapts.
Compared with prior art, the advantage of this sintered coaxial cable is: 1, reasonable in design, simple in structure, be easy to processing and manufacturing, and production cost is lower.2, stable work in work is particularly suitable for work under the extreme operational environment such as high temperature, high pressure.3, long service life, the scope of application is extensive.
