Abstract
The utility model provides a kind of cable drawing head, including：One core, the core is provided with a conductor, a flame retardant coating and an insulating barrier, flame retardant coating described in the conductor outer cladding, insulating barrier described in the flame retardant coating outer cladding；The insulating barrier, which is externally provided with packed layer, the packed layer, is provided with glass cement；The packed layer is externally provided with a sheath, and the sheath is externally provided with a steel-tape armouring, and the steel-tape armouring is externally provided with an oversheath.Compared to prior art, glass cement is provided with the packed layer of cable drawing head of the present utility model, the glass cement plays a part of sealing, the packed layer is located between the core and the sheath, even if the oversheath is torn off, the packed layer can also play a part of waterproof so that the good water-proof effect of this kind of cable drawing head.
Description
Technical field
The utility model is related to a kind of cable, espespecially a kind of cable drawing head.
Background technology
It is required to use net, steel wire rope during cabling generally in built-in pipe or pre-fabricated electric cables ditch, twists the works such as mill
Tool, water-proofing treatment has all been made before construction to cable drawing head, and the water-proofing treatment done is typically that cable drawing head is wrapped up.
But actually no matter how firm your wrapping to cable drawing head is, head will be wrapped up by crossing big city due to tractive force in distraction procedure
Pull off.If the more slightly worse cable of quality, the oversheath being located in wrapping head is all pulled off one section, and wrapping head does not rise
Effect, waterproof effect is poor.
Therefore, it is necessary to a kind of new cable drawing head be designed, to overcome above mentioned problem.
Utility model content
The utility model provides a kind of cable drawing head of good water-proof effect.
The technical solution adopted in the utility model is：A kind of cable drawing head, including：One core, the core is provided with one
Conductor, a flame retardant coating and an insulating barrier, flame retardant coating described in the conductor outer cladding, insulating barrier described in the flame retardant coating outer cladding；
The insulating barrier, which is externally provided with packed layer, the packed layer, is provided with glass cement；The packed layer is externally provided with a sheath, described interior
Sheath is externally provided with a steel-tape armouring, and the steel-tape armouring is externally provided with an oversheath.
Further, the packed layer is provided with pitch.
Further, the core is 3.
Further, the packed layer is provided between the core.
Further, core distribution triangular in shape.
Compared to prior art, glass cement, the glass cement are provided with the packed layer of cable drawing head of the present utility model
Play a part of sealing, the packed layer is located between the core and the sheath, even if the oversheath is torn off, institute
Waterproof can also be played a part of by stating packed layer so that the good water-proof effect of this kind of cable drawing head.
Brief description of the drawings
Accompanying drawing is to be further understood for providing to of the present utility model, and constitutes a part for specification, and following
Embodiment is used to explain the utility model together, but should not constitute to limitation of the present utility model.In the accompanying drawings,
Fig. 1：The sectional view of the utility model cable drawing head.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
As shown in figure 1, cable drawing head of the present utility model, including a core 1, the core 1 is externally provided with a packed layer
2, the packed layer 2 is externally provided with a sheath 3, and the sheath 3 is externally provided with a steel-tape armouring 4, and the steel-tape armouring 4 is externally provided with
One oversheath 5.
The core 1 is provided with a conductor 11, and the conductor 11 is externally provided with a flame retardant coating 12, and the flame retardant coating 12 is externally provided with one
Insulating barrier 13, sets the flame retardant coating 12, prevents that the heating of conductor 11 from causing fire, prevents that whole cable from coming into the picture and burn；
It is to prevent electric leakage etc. and injure operating personnel to set the insulating barrier 13.In the present embodiment, the core 1 is 3, the line
Arrangement triangular in shape between core 1.Packed layer 2 is provided between the core 1, it is ensured that all there is packed layer 2 around core 1 and reach
To more preferable waterproof effect.
The packed layer 2 is provided with glass cement, and the glass cement plays a part of sealing, prevents that water penetration from, in core 1, making
The waterproof effect for obtaining the cable drawing head is more preferable.The glass cement is that before laying, the glass cement is exerted oneself with thumb
Packed layer 2 is pressed into, is then deployed to surrounding, firmly the glass cement of bigger press-in is more.Or added in the packed layer 2
Pitch, heats the pitch, allows the glass cement to penetrate into the packed layer 2.Or first with thumb into packed layer 2
Glass cement is pressed into, pitch is added and the glass cement is penetrated into the packed layer 2 pitch heating.Add the glass cement
Afterwards, it is sealing between the sheath 3 and the core 1, plays more preferable waterproof effect.
To sum up, cable drawing head of the present utility model adds glass cement in packed layer 2 so that packed layer 2 is one layer close
Sealing so that the cable drawing head adds the packed layer 2 as waterproof layer again in addition to provided with oversheath 5, sheath 3,
So that the waterproof effect of the cable drawing head is more preferable.
Various not be the same as Examples of the present utility model are carried out any group by the thought created without departing from the utility model
Close, should be considered as the utility model disclosure；In range of the technology design of the present utility model, technical scheme is carried out
Any combination for the thought created without prejudice to the utility model that a variety of simple modifications and non-be the same as Example are carried out, all should be at this
Within the protection domain of utility model.
