Description

Computer shielding control cable

Technical field

The utility model is related to a kind of cable, specifically a kind of computer shielding control cable.

Background technology

Computer is mainly used for computer power supply with shielding control cable, to be used as to convey electric energy, has in many industries It is widely used.As computer technology is in the extensive use of industry-by-industry, computer is got over the demand of shielding control cable Come bigger, it is desirable that higher and higher.But the existing computer construction of cable is loose, compressive property is weak, and it is dry to be vulnerable to electromagnetism It disturbs, influences promoting the use of for computer technology.

Utility model content

Technical problem to be solved in the utility model is to be directed to above-mentioned technical deficiency, provides a kind of insulating properties Good, strong anti-interference performance and novel computer with long service life shielding control cable.

In order to solve the above technical problems, technical solution used by the utility model is：A kind of novel computer shielding Cable is controlled, is disposed with core, packing material, shielded layer, liner layer, armor and sheath, the line from inside to outside Core includes conductor, the extruded insulation layer on conductor；The core of described two different colours is twisted into pair, using non-hygroscopic when pair twist Property material fill rounding, two pairs or more of line strand stranding, when stranding, fills non-absorbent material；It is wrapped outside the cable core Shielded layer, wrapped suitable non-moist belt outside the shielded layer.

The technical program is advanced optimized, wrapped two layers suitable non-hygroscopic band are overlapped between the core and shielded layer Son.

The technical program is advanced optimized, the shielded layer is made of annealed copper wire or tinned wird braiding, and braiding is close Degree is not less than 80%.

The technical program is advanced optimized, the liner layer is wrapped using polyvinyl chloride, polyethylene, perfluoroethylene-propylene It forms.

Compared with prior art, the utility model has the following advantages：

1, more reasonable structure is simple, and manufacture is easy, and cost is relatively low.

2, reliable working performance, high shielding, sound construction, safety and environmental protection.

Description of the drawings

Fig. 1 is computer shielding control cable sectional view.

In figure：1, conductor；2, insulating layer；3, packing material；4, wrapping layer；5, shielded layer；6, liner layer；7, armor； 8, sheath.

Specific implementation mode

To make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment And with reference to attached drawing, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want Limit the scope of the utility model.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid not Necessarily obscure the concept of the utility model.

Specific implementation mode：A kind of computer as shown in Figure 1 shielding control cable, sets gradually wired from inside to outside Core, packing material 3, shielded layer 5, liner layer 6, armor 7 and sheath 8, the core include conductor 1, are extruded on conductor Insulating layer 2；The core of described two different colours is twisted into pair, fills rounding using non-absorbent material 3 when pair twist, two pairs and Above line strand stranding fills non-absorbent material 3 when stranding；The outer lapped shielding layer 5 of the cable core, the shielded layer Wrapped suitable non-moist belt outside 5.

Preferably, the wrapping layer 4 of wrapped two layers suitable non-hygroscopic belt is overlapped between the core and shielded layer.

Preferably, the shielded layer is made of annealed copper wire or tinned wird braiding, and count is not less than 80%.

Preferably, the liner layer using polyvinyl chloride, polyethylene, perfluoroethylene-propylene is wrapped forms.

In the specific implementation, insulated wire cores should be twisted into pair the utility model, and pair twist pitch should be not more than 100mm, stranding When outermost direction of lay to the right, for the strand of each adjacent layer on the contrary, pitch is not more than 16 times of twisted outer diameter, sheath should be close It is extruded on clad, and should be easily peeled off without damaging clad, the utility model core is symmetrical so that in cable core Distribution of Magnetic Field is uniform, can harmonic carcellation, on the other hand strong antijamming capability core and covers and increases wrapping layer between layer, make Cable wire is soft, contribute to the shielding properties for enhancing cable, make that its insulating properties is good, strong anti-interference performance, service life is long.

It should be understood that the above-mentioned specific implementation mode of the utility model is used only for exemplary illustration or explains this reality With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model In the case of any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.In addition, The appended claims for the utility model are intended to cover to fall into attached claim scope and boundary or this range and boundary Whole change and modification examples in equivalent form.
