Description

A kind of silicon rubber insulation shielded cable

Technical field

The utility model relates to field of cable technology, specially a kind of silicon rubber insulation shielded cable.

Background technique

With the development of science and technology, the place that cable uses in people's lives is more and more, ring is used in various electronics In border, cable plays indispensable status, but since the use environment of cable becomes increasingly complex, so cable is by various The influence of electronic equipment and other cables is also increasing, and common cable has been increasingly difficult to meet in complex environment The purpose used could allow data transmission to keep normal, In so must assure that every cable all has the function of that oneself is shielded So-called shielding on the construction of cable, substantially a kind of measure for improving field distribution, cable conductor be twisted by stranded conductor and At it easily forms air gap between insulating layer, and conductive surface is rough, will cause electric field concentration, in conductive surface plus one and half The shielded layer of conductive material, it and shielded conductor equipotential, and well contacted with insulating layer, to avoid in conductor and absolutely Shelf depreciation occurs between edge layer, in insulating surface and sheath contact position, it is also possible to there are gap, when cable bend, oilpaper electricity Cable insulating surface easily causes crackle, these are all the factors for causing shelf depreciation.

The utility model it has been found that existing common cable structure is simple, be prone to wear, do not have in use There is corresponding insulation screen structure, so screening ability is poor, is easy to be not suitable for by externalities in more cable and magnetic field Biggish place distribution.

Utility model content

The purpose of this utility model is to provide a kind of silicon rubber insulation shielded cables, it is intended to improve traditional construction of cable Simply, it is easy to produce abrasion in use, and without corresponding insulation screen structure, it has not been convenient in more cable and magnetic The problem of biggish place in field is distributed.

The utility model is realized in this way:

A kind of silicon rubber insulation shielded cable, including external protection, insulating layer and interior cable core, the external protection include silicon Rubber sleeve and shielding strip, the shielding strip is uniformly arranged along silicone rubber sleeve circumferencial direction, and shielding strip is fixedly mounted on silicon rubber The inside of set, the insulating layer include clad and restrictive coating, and the clad is arranged on the lateral surface of restrictive coating, and are coated Layer is fitted closely with restrictive coating, and the interior cable core includes filled core, control conductor and wire core, the control conductor and wire core It is uniformly arranged on the inside of restrictive coating, and control conductor and wire core pass through filled core and fit closely with restrictive coating, by right Traditional Cable structure is improved, and wear-resisting durable and double layer screen the effect of cable is effectively realized, by external The structure of protective layer is improved, and the effect for also effectively accomplishing shielding while increasing cable abrasion resistant effect to internal cable line is realized Fruit, the structure setting of insulating layer are used to guarantee flexible in cable use process while it is also ensured that with the contact of interior cable core Cooperation can also be effective while being convenient between different cores stable install and use by the structure setting of internal cable core Guarantee mutually to shield between core, increases the effect of shielding.

Further, strip bulge, and strip bulge and restrictive coating one are evenly arranged on the restrictive coating medial surface Molding, will not be because of cable come the stability being convenient between restrictive coating and interior cable core by the setting to jacket layer inner stripe protrusion The problem of mutually winding between biggish deflection and interior cable core is occurring in the use process of dragging.

Further, it is provided with internal shield on the control conductor and ground wire core outer surface, the internal shield is adopted With copper wire material used, by the limitation of the structure design and use material to internal shield, as control conductor and wire core Internal shield uses, and can effectively prevent the interference between control conductor and wire core, can also to avoid cable outside Influence to cable.

Further, the filled core is made of the compression of several gum fillers, and gum filler uses silastic material, is led to The limitation to the structure design and use material of filled core is crossed, to guarantee mutual stabilization and the insulating layer between different cores It is relatively stable between interior cable core, and by the restriction of silastic material can guarantee that process will not be squeezed in cable In internally cable core damage.

Further, the clad uses compound type non-woven fabric material, is reached by the structure qualification to clad Moisture-proof, ventilative, flexible, light and not combustion-supporting purpose, and it is cheap, it is used convenient for a large amount of.

Further, the restrictive coating uses silastic material, is limited by the material to restrictive coating, and Lai Tigao cable is resistance to High temperature, low temperature resistant and waterproof performance purpose.

Further, the shielding strip uses metal material, is defined by the material to shielding strip, in order to not increase Add under the premise of manufacturing cost and improves the shield effectiveness of shielding strip.

Compared with prior art, the utility model has the beneficial effects that the utility model passes through to traditional cable knot Structure is improved, and is effectively realized wear-resisting durable and double layer screen the effect of cable, is changed by the structure to external protection Into, realize increase cable abrasion resistant effect while also effectively to internal cable line accomplish shielding effect, the knot of insulating layer Structure setting is used to guarantee flexible in cable use process while it is also ensured that being engaged with interior cable core, by internal While the structure setting of cable core is installed and used to be convenient for stablizing between different cores, it can also effectively guarantee phase between core Mutually shielding, in order to avoid influence each other.
