Signal transmission line structure

Technical field

The present invention relates to a kind of signal transmission line.

Background technology

The signal line that tradition is commonly used, the conductor of this transmission signal can be divided into haply that single conductor or multi-core conductor are stranded to form, with single conductor is example, coaxial wire structure as shown in Figure 1, it is characterized in that: the insulator that this conductor 1 is coated, be round tubular body 2, make with aluminium pool wheat drawstring 3, copper cash braiding shielding layer 4 and PVC cladding 6 and be combined into a coaxial cable with the PE extrusion molding.

Above-mentioned coaxial cable is the solid shape PE pipe of mat extrusion molding, so that capacitance is minimized, attenuation can be less.Yet because the insulation effect of PE is not best, and this shielding layer also can't be reached absolutely and cover, and therefore, the degree of magnetic field, radio frequency and the mutual interference of static phase is still higher, and this transmission signal can produce refraction or reflex during transmission, all is problems of separating extremely co-pending.

Summary of the invention

Technical problem to be solved by this invention is, above-mentioned deficiency at prior art, and provide a kind of height, frequent separating to transmit with signal, to reduce the signal transmission line of kelvin effect, this signal transmission line transmission speed is fast, decay is low, distortion is little and high-quality, and has effects such as the static of reduction, minimizing radio frequency and magnetic interference.

Above-mentioned technical problem of the present invention is realized by following technical scheme.

A kind of signal transmission line structure is made of core portion, intermediate layer of material and outer coating layer, it is characterized in that:

This core portion comprises that two carry medium, and two carry medium to be provided with insulating barrier separately;

Be somebody's turn to do outer coating layer, be provided with one deck at least; And

This intermediate layer of material, being situated between places between core and the outer coating layer, by the PVC conductive layer, at least one deck the metal wire braid and wrap the ply of paper cooperation and constitute, the mat multi-core conductor transmits the high and low frequency of signal separately.

Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:

One transport medium of this core portion is the fine silver conductor, and it is coated with the PE insulating barrier.

Another transport medium of this core portion be enamel-cover single crystals folk prescription to pure cu conductor, it is coated with the PE foaming layer.

This at least the metal wire braid of one deck be silver jacketed wire.

This intermediate layer of material is that PVC conductive layer, metal wire braid and bag ply of paper are to constitute the guitar line.

This intermediate layer of material is that PVC conductive layer, metal wire braid, PTFE layer and metal wire braid are to constitute the video signal line structure.

This microphone lines structure is to be made of two independent core portions.

This intermediate layer of material is PVC conductive layer, cotton yarn packed layer, metal wire braid and bag ply of paper.

The invention has the advantages that:

The mat multi-core conductor separately transmits the high and low frequency of signal separately, unlikely phase mutual interference can reduce kelvin effect (skin effect), simultaneously by the shielding layer more than one deck, reduce the interference of magnetic field, radio frequency and static, so the transmission characteristic low, that distortion is little, quality is high that can decay.

Below by instantiation, conjunction with figs. is to the present invention, does a detailed explanation as the back:
