Technical field

The utility model relates to field of cables, specially a kind of mica tape mineral insulation ripple copper sheath cable.

Background technique

Cable, usually by several or the cable of similar rope that several groups of conducting wires (every group at least two) are twisted, often Mutually insulated between group conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation, cable tool There are interior energization, the feature of external insulation, cable can be divided into power cable, control cable, compensating cable, shielded cable, high-temperature electric Cable, computer cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..

In the prior art, the non metallic sheath of cable connect with other internal components very closely, cause with line when It waits, is difficult to remove non metallic sheath, moreover, needing another wiring in ripple copper sheath ground connection, operation is cumbersome, in addition, When in use, it is easy cable bend excessively leading to cable bad.

Utility model content

The purpose of this utility model is to provide a kind of mica tape mineral insulation ripple copper sheath cables, to solve above-mentioned back The problem of proposed in scape technology.

To achieve the above object, the utility model provides the following technical solutions: a kind of mica tape mineral insulation ripple copper shield Cable, including non metallic sheath are covered, the non metallic sheath innermost layer is equipped with reinforcing bar, and the reinforcing bar outer surface is wound with multiple cores Line, multiple core wires and reinforcing bar form core, and the core is externally provided with the first filler, shielding is arranged with outside the core Layer, is arranged with mica tape outside the shielded layer, and the mica tape outer surface is arranged with ripple copper sheath, outside the ripple copper sheath Surface is equipped with iron wire, and waterproof layer is arranged with outside the ripple copper sheath.

Further, the core wire is equipped with mica set and copper core, and mica set is set in copper core outer surface.

Further, the copper core is entwined by more copper wire.

Further, the second filler is filled between the copper core and mica set.

Further, the diameter of the iron wire is between one millimeter to two millimeters.

Further, the iron wire is spirally wound on ripple copper sheath outer surface.

Further, the non metallic sheath is set in waterproof layer outer surface.

Compared with prior art, the utility model has the beneficial effects that firstly, passing through the reinforcing bar of setting, the hardness of reinforcing bar It is larger, it is difficult to be bent, is difficult curved transitions so as to cause the cable, ensure that the safety operation of cable installation process, secondly, It, can be by being pulled outwardly when shelling non metallic sheath by the iron wire of setting, and by iron wire spiral wound on ripple copper sheath The mode of iron wire cuts off non metallic sheath and waterproof layer, thus facilitate stripping non metallic sheath, meanwhile, it is connect by ripple copper sheath When ground, directly iron wire is grounded, avoids the operation of other wiring.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of embodiment: a kind of mica tape mineral insulation ripple copper sheath electricity Cable, including non metallic sheath 1,1 innermost layer of non metallic sheath are equipped with reinforcing bar 9, and reinforcing bar 9 is located at the bosom of entire cable, In When design, the reinforcing bar 9 for selecting differently curved difficulty can according to need, it, can be to avoid the cable bend by the reinforcing bar 9 of setting Excessively, it ensure that the safety operation of cable installation process, 9 outer surface of reinforcing bar is wound with multiple core wires 11, and core wire 11 is mainly used for Conduction, multiple core wires 11 form core 12 with reinforcing bar 9, and core 12 is externally provided with the first filler 8, and the first filler 8 is that mineral are exhausted Edge substance is arranged with shielded layer 5 outside core 12 for the insulation between core wire 11, avoids external magnetic field and generates shadow to cable It rings, is arranged with mica tape 4 outside shielded layer 5, in scene of fire, the component damage that mica tape 4 can wrap up to avoid mica tape 4, cloud 4 outer surface of master tape is arranged with ripple copper sheath 3, and 3 outer surface of ripple copper sheath is equipped with iron wire 10, is grounded by ripple copper sheath 3 When, directly iron wire 10 is grounded, the operation of other wiring is avoided, waterproof layer 2 is arranged with outside ripple copper sheath 3.

Further, core wire 11 is equipped with mica set 6 and copper core 7, and mica set 6 is set in 7 outer surface of copper core, fire compared with Big occasion, mica set 6 can avoid copper core 7 impaired to avoid protection copper core 7.

Further, copper core 7 is entwined by more copper wire 13.

Further, the second filler 14 is filled between copper core 7 and mica set 6, the second filler 14 is that minerals are exhausted Edge substance, for avoiding copper core 7 from leaking electricity.

Further, the diameter of iron wire 10 is easier to non metallic sheath 1 between one millimeter to two millimeters Cut off, and avoid iron wire 10 fracture.

Further, iron wire 10 is spirally wound on 3 outer surface of ripple copper sheath, and by 10 spiral wound of iron wire in ripple copper On sheath 3, when shelling non metallic sheath 1, non metallic sheath 1 and waterproof layer 2 can be cut by way of outside bracing wire 10 It is disconnected, to facilitate stripping non metallic sheath 1.

Further, non metallic sheath 1 is set in 2 outer surface of waterproof layer, and non metallic sheath sheath 1 is located at outermost, uses In protection metal material framework, metal material component dampness is avoided to get rusty, into ash etc..

Working principle: firstly, when stripping non metallic sheath 1, plumbness bracing wire 10, iron wire can be kept with cable Non metallic sheath 1 and waterproof layer 2 are cut out helical opening by 10, so as to directly by non metallic sheath 1 and waterproof layer 2 therefrom It strips down, and in wiring, directly ripple copper sheath 3 can be grounded by iron wire 10, avoid the operation of other wiring, It is secondary, during installation, be difficult to be bent since reinforcing bar 9 compares, therefore, it is difficult to by cable bend to design minimum bend diameter with Under, to ensure that the cable safety in installation process.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
