Abstract
The utility model provides a kind of cable indoor terminal, including the cable and insulation sleeve being arranged successively from inside to outside, nitrogen is filled between the cable and the insulation sleeve, the insulation sleeve outside wall surface is equipped with multiple umbrella shape dead rings, the endless metal silk screen coordinated with the dead ring is embedded in the dead ring, the insulation sleeve is equipped with multiple springs across the woven wire along axis.A kind of cable indoor terminal provided by the utility model, using setting woven wire in insulation sleeve, greatly improve product elastic strength, ensure that its sealing performance, so as to avoid interior gold utensil is made to be corroded due to steam invades, insulator interface by destroy cause breakdown, cable major insulation reduced performance the problems such as occur.
Description
Technical field
The utility model is related to cable termination manufacturing technology field, more particularly to a kind of cable indoor terminal.
Background technology
At present, it at home and abroad in power cable indoor terminal rubber, because its elastic strength is inadequate, is in for a long time
Easily occur fatigue in the case of stretching, its sealing performance is made to be deteriorated, easily steam is allowed to enter.So as to cause gold utensil in terminal rotten
The generation for phenomena such as erosion, insulator interface destroyed, and causes breakdown, the reduced performance of cable insulation.
Utility model content
Technical problem to be solved in the utility model is：In order to overcome cable indoor terminal elastic strength in the prior art
Inadequate deficiency, the utility model provide a kind of cable indoor terminal.
The utility model solves its technical problem technical solution to be taken：A kind of cable indoor terminal, including by
The cable and insulation sleeve being arranged successively from inside to outside, are filled with nitrogen between the cable and the insulation sleeve, outside the insulation sleeve
Wall surface is equipped with multiple umbrella shape dead rings, and the endless metal silk screen coordinated with the dead ring, institute are embedded in the dead ring
It states insulation sleeve and is equipped with multiple springs across the woven wire along axis.
Setting woven wire increases the elastic strength of insulation sleeve radial direction in dead ring, and spring connects each woven wire for increasing
The elastic strength of strong insulation sleeve axial direction, the two combine the elastic strength for greatly strengthening insulation sleeve, ensure that its sealing performance, from
And avoid interior gold utensil is made to be corroded due to steam invades, insulator interface by destroy cause breakdown, cable major insulation performance
The generation of the problems such as reduction.
Further, in order to which nitrogen-sealed is stored, ensure the insulating properties of cable indoor terminal, the insulation sleeve input end is set
There is seal assembly, the seal assembly includes pressure ring and sealing ring, and the sealing ring includes sealing and connecting portion, the sealing
Portion be arranged on the cable side wall, the connecting portion for loop configuration be set on the sealing outside wall surface on, the pressure ring set
The one end of the sealing ring far from the insulation sleeve is set on the cable, the connecting portion is located in the pressure ring and institute
It states between insulation sleeve.
The beneficial effects of the utility model are：A kind of cable indoor terminal provided by the utility model, using in insulation sleeve
Woven wire is set, product elastic strength is greatly improved, ensure that its sealing performance, so as to avoid due to steam invades
Interior gold utensil is made to be corroded, insulator interface by destroy cause breakdown, cable major insulation reduced performance the problems such as occur.

Specific embodiment
The utility model is described in detail presently in connection with attached drawing.This figure is simplified schematic diagram, only in a schematic way
Illustrate the basic structure of the utility model, therefore it only shows the composition related with the utility model.
As shown in Figs. 1-3, a kind of cable indoor terminal of the utility model, including the cable 1 being arranged successively from inside to outside
With insulation sleeve 2, nitrogen is filled between the cable 1 and the insulation sleeve 2,2 outside wall surface of insulation sleeve is equipped with multiple umbrellas
Shape dead ring 3, is embedded with the endless metal silk screen 4 coordinated with the dead ring 3 in the dead ring 3, and the insulation sleeve 2 is along axis
Line is equipped with multiple springs 5 across the woven wire 4.
2 input end of insulation sleeve is equipped with seal assembly, and the seal assembly includes pressure ring 6 and sealing ring 7, the sealing
Circle 7 includes sealing 7-1 and connecting portion 7-2, the sealing 7-1 be arranged on 1 side wall of cable, the connecting portion 7-2
It is set in the sealing 7-1 outside wall surfaces for loop configuration, the pressure ring 6, which is sheathed on the cable 1, is set on the sealing ring 7
One end far from the insulation sleeve 2, the connecting portion 7-2 are located between the pressure ring 6 and the insulation sleeve 2.
Using the above-mentioned desirable embodiment according to the utility model as enlightenment, by above-mentioned description, relevant work
Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model
Technical scope is not limited to the content on specification, it is necessary to determine its technical scope according to right.
