Abstract
The invention discloses a high-speed low-loss mixed medium differential transmission signal line structure which is characterized by comprising a main body, conductors, first insulting layers, a second insulating layer, a shielding layer, a mylar layer and a ground line. The first insulating layers wrap the conductors so as to form core wires. The two core wires are arranged in parallel or mutually twisted and wrapped by the second insulating layer and the shielding layer in turn to form a wrapped line, and the first insulating layers of the two core wires are connected as a whole body through PE extrusion. The beneficial effects of the high-speed low-loss mixed medium differential transmission signal line structure are that the high-speed low-loss mixed medium double coaxial differential transmission signal line is stable in impedance, more excellent in transmission performance and lower in insertion loss so that the transmission distance is longer, the transmission bandwidth can be increased, the physical size of the line can be smaller and the space occupation can be reduced; the larger shielding area can be realized, coupling between the signal line conductors can be increased and coupling between the conductors and shielding can be reduced; and differential and common mode impedance can be better tuned.

Technical field
The present invention relates to a kind of holding wire, specially high speed low-loss blending agent differential transmission signals line structure, belong to
Communication field of material technology.
Background technology
Holding wire is primarily referred to as being used for the circuit for transmitting heat transfer agent and control information in electric control circuit.Holding wire
A branch of or multi beam transmission line is configured to a plurality of cable often, it is also possible to the track being aligned in printed circuit board, with
The continuous progress of science and technology and application, holding wire develops into other carriers, such as optical cable etc. by metallic carrier.The letter of different purposes
Number line often has different industry standards, in order to production and the application of standardizing.
Uniformity signal line product has the disadvantage that in the market：
1. all it is to be insulated as single-ended signal using extrusion on single conductor, due to separating during single-ended signal (heart yearn) extrusion
Extrusion, has differences between holding wire, not smart enough the Huaihe River of concordance control, two single-ended signals and put by the shielding materials such as aluminium foil come
Constraint is used as carrier carries out the transmission of signal, easily can be acted on by external force in constraint, and heart yearn is susceptible to deformation
Cause conductor centre-to-centre spacing unstable, cause impedance to produce mutation, affect characteristics of signals transmission.
2. specification is fixed, and centre-to-centre spacing is just fixed, it is impossible to be adjusted, and space hold is than larger.
3. specification must be reduced if size to be reduced, then laser propagation effect is obviously reduced, insertion under equal length is damaged
Consumption substantially increases.
4. conductor closes larger with shielding Rhizoma Nelumbinis, and common mode loss increases.
The content of the invention
It is an object of the invention to provide a kind of high-transmission low-loss can realize the low damage of the high speed of more longer transmission distance
Consumption blending agent differential transmission signals line structure, to solve the problems, such as to propose in above-mentioned background technology.
The purpose of the present invention is achieved by following technical proposals:High speed low-loss blending agent differential transmission signals
Line structure, it is characterised in that：Including main body, conductor, the first insulating barrier, the second insulating barrier, screen layer, mylar layers and ground wire,
First insulating barrier wraps up conductor so as to constitute heart yearn, and heart yearn described in two is simultaneously put or is mutually paired and passes through the second insulating barrier
It is wrapped line with the screen layer composition that is wrapped successively, and the first insulating barrier of two heart yearns is connected as a single entity by PE extrusions, the mylar layers
The line that will be wrapped constitutes signal line structure main body with ground wire parcel.
First insulating layer material of the present invention is Skin-Foam-Skin or HDPE.
Second insulating barrier of the present invention is EPTFE layers, and EPTFE layers are formed by EPTFE band windings, winds Duplication
For 50%.
Screen layer of the present invention is that aluminium foil wheat is drawn or Copper Foil wheat is drawn.
Conductor of the present invention is naked copper or silver-plated copper of the size in 34～22AWG.
Ground wire Cai of the present invention is Yong Round's or flat conductor is made.
The invention has the beneficial effects as follows：Originally it is bright to disclose a kind of double coaxial differential transmission signals of high speed low-loss blending agent
Line, by the disposable extrusion disjunctor insulation of two-conductor, can effectively control the distance between disjunctor, damage impedance stabilization, insertion
Consumption, return loss etc. are more stable, improve the concordance of product；Conductor center distance can be changed by adjusting disjunctor width；
Carry out the mixing of different insulative medium on this basis again, reach in-between dielectric constant after a kind of synthesis, make transmission
Performance is more excellent, and insertion loss is lower, and such as one PE dielectric constants of this example insulation are 2.3, and two EPTFE dielectric constants of insulation are 1.3, comprehensive
Dielectric constant after conjunction is 1.8 or so；Bigger wire gage can be selected after the center distance that product gives, can be transmitted
Longer distance, increases transmission bandwidth, while wire rod physical size can be less, reduction is taken up space；Bigger screen can be possessed
Lee-side is accumulated, and the Rhizoma Nelumbinis that can increase between holding wire conductor are closed, and the Rhizoma Nelumbinis reduced between conductor and shielding are closed；Mediation difference that can be more excellent with
Common code impedance.
