Description

A kind of high voltage low inductance cable of knitted conductor structure

Technical field

The utility model relates to a kind of high voltage low inductance cable, particularly relates to the height of a kind of knitted conductor structure Pressure low-inductance cable.

Background technology

With the needs of war industry, wireless pulse technology have been widely used for radar, remote control, In the various electronic equipment such as multichannel communication multiple telecommunication.Pulse in order to impulse generator is produced is transferred to various equipment In load, centre will be attached by cable, and high voltage low inductance cable is exactly special transferring high voltage pulse 's.As pulse technique is to high voltage, burst pulse, momentary high power development, to high voltage low inductance cable Propose the requirement of the aspects such as inductance high pressure resistant, low, low decay, shielding and flexibility.

Current conventional use of high voltage low inductance cable general appearance size is all relatively big, and internal structure is solid Polyethylene, it is impossible to use under too small bending radius, in case conductor disengages with insulation, it may occur that Insulate breakdown danger.

Utility model content

The purpose of this utility model is to solve the problems of the prior art, provides a kind of knitted conductor structure High voltage low inductance cable.

The technical solution of the utility model is: the center of described cable is for filling out core, and described cable is from interior To being made up of fill out core, inner wire, insulating barrier, outer conductor and the oversheath that are arranged concentrically successively outward；Described Fill out core and use glass cord；Described inner wire and outer conductor use multiply silver-plated circular copper wire braiding structure； Described insulating barrier uses fluoroplastics material；Described oversheath uses pvc material.

Preferably, the described glass cord filling out a diameter of 1.75 ± 0.05mm of core employing.

Preferably, described inner wire is formed by the braiding of multiply silver-plated circular copper wire, and count is not less than 90%.

Preferably, described outer conductor is formed by the braiding of multiply silver-plated circular copper wire, and count is not less than 90%.

Preferably, described oversheath uses the pvc material of black.

The utility model has the advantages that

1) low inductance characteristic: have employed the special of " filling out core-inner wire-insulation-layer outer conductor-oversheath " Concentric structure, by using braiding structure, can expand inner wire diameter, increase between internal and external conductor Corresponding area, insulating barrier uses thin-walled extrusion way simultaneously, it is ensured that the inductance value of cable is not more than 60nH/m (1MHz)。

2) high pressure resistant property: by using the fluoroplastics material with excellent electrical and excellent machinability As insulating barrier, balancing the requirement of high pressure resistant and low two key characteristic indexs of inductance, optimal insulation is thick Degree controls between 0.35mm～0.4mm, it is ensured that the use of cable resistance to 6000V high direct voltage requires.

3) flexural property: filled out core material by using the excellent glass cord of resistance to elevated temperatures, inside and outside lead Body multiply silver-plated circular copper wire braiding structure and soft polyvinyl chloride jacket material, Cable Bending Radius is controlled System, at about 40mm, drastically increases the flexibility of cable.

Brief description

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

For the technological means, technical characteristic, utility model purpose and the technology effect that make the utility model realize Fruit is easy to understand, and below in conjunction with being specifically illustrating, the utility model is expanded on further.

As it is shown in figure 1, be the high voltage low inductance cable of a kind of knitted conductor structure of the present utility model, should The center of cable for filling out core 1, around described fill out core 1 from the inside to the outside successively be coated with inner wire the 2nd, insulate Layer the 3rd, outer conductor 4 and oversheath 5.Described fill out core the 1st, inner wire the 2nd, insulating barrier the 3rd, outer conductor 4 and Oversheath 5 is concentric structure.

The present embodiment fills out the glass cord that core 1 uses a diameter of 1.75mm ± 0.05mm, this reality Execute and example uses 1.75mm be optimal.Be coated with inner wire 2 in the outside filling out core 1, inner wire 2 by The silver-plated circular copper wire braiding of 16 a diameter of 0.10mm forms, and count is not less than 90%.Lead interior What the surrounding of body 2 was coated with is insulating barrier 3, and this insulating barrier 3 uses fluoroplastics (PFA) material；Around The outside covering of insulating barrier 3 is outer conductor 4, and this outer conductor 4 is by the plating of 16 a diameter of 0.10mm Silver dollar copper wire woven forms, and count is not less than 90%.Cover in the outside of outer conductor 4 is outer protecting Set 5, oversheath 5 is black pvc material.

The utility model have employed the special Heart-to-Heart of " filling out core-inner wire-insulating barrier-outer conductor-oversheath " Structure, expands inner wire diameter by braiding structure, increases the corresponding area between internal and external conductor, to reduce Distance between them, effectively reduces inductance.

Core of filling out in the utility model uses the excellent glass cord material of resistance to elevated temperatures, internal and external conductor All use multiply silver-plated circular copper wire braiding structure, drastically increase the flexibility of cable.

In addition, insulating barrier use can thin-walled extrusion, the fluoroplastics material of excellent electrical property, oversheath use Resistant to elevated temperatures soft polyvinyl chloride material, it is ensured that cable is high pressure resistant, low inductance performance while, further Improve the flexibility of cable and reducing the appearance and size of cable, the outside diameter of cable can control at 5mm Within.

It is only the utility model preferred embodiment in sum, be not used for limiting reality of the present utility model Execute scope.I.e. all equivalences made according to the content of the utility model claim change and modify, all Technology category of the present utility model should be belonged to.
