Description
Technical field
The present invention relates to cable fields, in particular to LSOH anti-flaming cable.
Background technique
Cable is the general designation of optical cable, cable and other items.There are many uses of the cable, is mainly used for control installation, connection is set
It is standby, the multiple actions such as transmit electric power, be a common and indispensable thing in daily life.Since cable charges, so
It is especially careful that installation needs.
Current cable is typically necessary is peeled off using tool, is docked to expose conducting wire, can specifically be joined
It is patent disclosed in CN208400592U, including three conducting wires according to notification number, is cased with insulating layer on the outside of three conducting wires, it is described
It is cased with housing on the outside of insulating layer, the conducting wire includes copper core and the sheath on the outside of copper core, inside and outside the insulating layer
It is provided with the V-shaped groove faced, three conducting wires are arranged in isosceles triangle, at V-shaped groove face conductor spacing, the shield
The arc groove faced is provided with inside and outside layer.
When needing to peel housing and expose copper core, it is first cut out annular groove on the coat with scissors, then housing is peeled, connects
Insulating layer is scratched along V-shaped groove with icking tool, expose internal conducting wire, finally arcuately slot scratches sheath with icking tool.
The purpose of this programme is to design a kind of insulation sleeve that can be stripped on the outside of conducting wire without tool.
Summary of the invention
It is convenient in view of the deficiencies of the prior art, the present invention intends to provide a kind of LSOH anti-flaming cable
Strip insulation sleeve.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of LSOH anti-flaming line
Cable, the fire-retardant housing including multiple cores, outside insulating layer are filled in filled layer of the core between fire-retardant housing, described
Core includes conducting wire, the first insulation sleeve covered outside conducting wire, the second insulation sleeve covered outside the first insulation sleeve, first insulation
Uniform intervals are provided with the first disconnection area to set along its length, and uniform intervals are arranged second insulation sleeve along its length
There is the second disconnection area, first disconnects area by being formed along the first uniformly distributed connecting hole of the first insulation sleeve circumferencial direction, and second disconnects area
By being formed along the second uniformly distributed connecting hole of the second insulation sleeve circumferencial direction, the first disconnection area and the second disconnection area are staggered and set
It sets.
In this way, using wire cutting blade by the fire-retardant housing of cable, area is disconnected as line of demarcation using second, and two hands hold the respectively
Two disconnect the second insulation sleeve part at left and right sides of area, and rotation needs to remove the second insulation sleeve part of side, another portion later
Divide and grasps so that it can not rotate；Area is disconnected as line of demarcation using first later, and two hands hold first disconnection area or so respectively
First insulation sleeve part of two sides, rotation needs to remove the first insulation sleeve part of side later, and another part, which grasps, to be made
It is obtained not to be able to rotate.It is to promote the safety that cable uses that first disconnection area and the second disconnection area are arranged in a staggered manner this programme
Property.
Further, the cross section of first insulation sleeve is annular shape, and the cross section of second insulation sleeve is foreign side
The abnormal shape of inner circle is cyclic annular, and the cross section of affiliated fire-retardant housing is polygonal ring shape.
Wherein the cross section of inboard wall of the second insulation sleeve is circle, primarily to cooperating with the first insulation sleeve, the second insulation
The external wall cross-section of set is rectangular, and the cross section of fire-retardant housing is polygonal ring shape, so that the second insulation sleeve is not susceptible to turn round
Turn, the second disconnection area of such second insulation sleeve will not be broken in a situation of use.
Further, it is provided with mica tape on the inside of first insulation sleeve, mica tape is wrapped on the conducting wire.
Mica tape is a kind of high performance mica insulation product, has excellent high temperature resistance and flame resistance energy.Powder
Mica tape has good flexibility under normal conditions, the main refractory insulating layer suitable for various fire-resisting cables.Meeting open fire burning
When the volatilizations of harmful vapors is substantially not present, so the product is not only effective and very safe for cable.
Further, the pressure rate of mica tape should be greater than 50% and be no more than 53%.
Pressure rate general control is 50%, but 50% ratio is more difficult to control, is easy to happen punch-through, pressure rate
Bigger cost is bigger, therefore controls and should be greater than 50% in pressure rate and be no more than 53%.
Further, the wrapped number of plies of mica tape is 2 layers.
2 layers of the Mica tape number of plies can effectively promote resistance to fire intensity, and the wrapped mica tape that will lead to of more layers is easy quilt
Breakdown.
Further, filled layer includes at least one of magnesium oxide powder, ceramics rope, glass rock wool braided fabric.
The setting of filled layer is stablized for filling gap, the construction of cable, magnesium oxide powder, ceramics rope, the braiding of glass rock wool
Object is inorganic mineral, and structural property is stablized.
Further, the fire-retardant housing is extruded by halogen-free and low-smoke flame-retardant polyolefin.
Exhaust smoke level is low when low smoke halogen-free flame-retardant polyolefin is heated, and is halogen-free in itself, environmental protection.
Further, the first insulation sleeve and the second insulation sleeve are extruded by low smoke, zero halogen polyolefin.
Exhaust smoke level is low when low smoke halogen-free flame-retardant polyolefin is heated, and is halogen-free in itself, environmental protection.
In conclusion the invention has the following advantages: the cable that the present invention designs, environment protection heat-proof is good, while not
Easy damaged conducting wire.
