Description
Technical field
This utility model relates to a kind of taper composite casing type outdoor terminal, belongs to cable accessory technical field.
Background technology
Outdoor terminal is a kind of terminal connector in cable accessory, owing to compound shell type outdoor terminal has advantage lightweight, that be easily installed, and adopt all right safety anti-explosive of composite bushing, neighbouring personnel and electric equipment will not be injured, use wider general relative to porcelain bushing type outdoor terminal.In prior art, compound shell type outdoor terminal includes composite bushing, the middle part of composite bushing is provided with and is arranged on cable upper stress cone, the bottom of composite bushing is provided with tail pipe, dielectric it is filled with in composite bushing, for prevent dielectric and stress cone is compatible and proof stress cone with cable between pressure, outside winding of band-type material at stress cone, in order to make to realize between cable and tail pipe sealing, strip material on stress cone continues downwards to be wound to tail pipe, and strip material constitutes the sealing structure between cable and tail pipe.Along with the prolongation of the time of use, strip material intensity can reduce, and can cause that the pressure between stress cone and cable diminishes, cause dielectric strength to reduce；When, when the strip material relaxation resistance step-down of tailpipe, dielectric also can pass through strip material and leak.Therefore, it cannot be guaranteed that dielectric strength and sealed bottom performance, there is very big potential safety hazard in this outdoor terminal of the prior art.
Summary of the invention
The purpose of this utility model is in that to provide the taper composite casing type outdoor terminal that a kind of dielectric strength is high and sealed bottom performance is good.
This utility model adopts the following technical scheme that a kind of taper composite casing type outdoor terminal, including the composite bushing in up-small and down-big pyramidal structure, the top of composite bushing is connected to wire leading-out clamp, bottom is connected to tail pipe, the middle part of composite bushing is provided with the stress cone being arranged on cable, dielectric it is filled with inside composite bushing, what described composite bushing and tail pipe connected is provided externally with base, base is connected with support insulator, described stress cone is arranged with the stress cone protection set of monolithic construction, the bottom of described stress cone protection set extends to the top of tail pipe, in stress cone sealed bundle is trapped among by the top of stress cone protection set, the bottom of stress cone protection set coordinates with tail pipe top seal.
It is also filled with fluid sealant between described tail pipe bottom and cable.
Described stress cone protection set is made up of rubber.
Described dielectric is silicone oil.
There is outside described composite bushing big full skirt spaced apart and little full skirt.
Described tail pipe is provided externally with tail pipe protection set.
The beneficial effects of the utility model are: the stress cone protection set of this utility model sheathed monolithic construction on stress cone; stress cone and dielectric is made to keep apart; avoid dielectric and the compatible phenomenon of stress cone; the stress cone protection set of monolithic construction will not relax; the pressure between stress cone and cable can be kept always constant, thus ensureing dielectric strength；And stress cone protection set and tail pipe top seal coordinate, it is possible to prevent dielectric from leaking from tailpipe.Owing to stress cone of the present utility model protects set to be adopt monolithic construction, this utility model is installed very easy, has that dielectric strength height, sealed bottom performance be good, the advantage of long service life.
Preferably, between tail pipe bottom and cable, filling with sealant can prevent dielectric from leaking from tailpipe further.
Preferably, the advantage that the stress cone protection suite that rubber is made has good springiness, easily installation, long service life.
Preferably, the outer spaced size full skirt of composite bushing can strengthen the anti-pollution characteristic of outdoor terminal.
Preferably, tail pipe protection set is possible not only to protection tail pipe, prevents dielectric from leaking from tail pipe further, moreover it is possible to promote the insulating properties of whole outdoor terminal.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
nullThe structure of a kind of embodiment of this utility model is as shown in Figure 1，The taper composite casing type outdoor terminal of the present embodiment includes the composite bushing 1 in up-small and down-big pyramidal structure，Composite bushing 1 is outside has big full skirt 9-1 spaced apart and little full skirt 9-2，The top of composite bushing 1 is connected to wire leading-out clamp 2、Bottom is connected to tail pipe 6，Tail pipe 6 is provided externally with tail pipe protection set 11，Composite bushing 1 is internal is filled with dielectric 3，Dielectric 3 is silicone oil，What described composite bushing 1 and tail pipe 6 connected is provided externally with base 7，Base 7 is connected with support insulator 8，The middle part of composite bushing 1 is provided with the stress cone 4 being arranged on cable，Described stress cone 4 is arranged with the stress cone protection set 5 of monolithic construction，Described stress cone protection set 5 is made up of rubber，The bottom of described stress cone protection set 5 extends to the top of tail pipe 6，In stress cone 4 sealed bundle is trapped among by the top of stress cone protection set 5，The bottom of stress cone protection set 5 coordinates with tail pipe 6 top seal，It is also filled with fluid sealant 10 between described tail pipe 6 bottom and cable.
The stress cone protection set of this utility model sheathed monolithic construction on stress cone; stress cone and dielectric is made to keep apart; avoid dielectric and the compatible phenomenon of stress cone; the stress cone protection set long service life of monolithic construction, will not relax, the pressure between stress cone and cable can be kept always constant; thus ensureing dielectric strength; adopt the stress cone protection set of monolithic construction, install and make to have only to stress cone is protected set be enclosed within stress cone, there is easy-to-install advantage.And stress cone protection set and tail pipe top seal coordinate, it is possible to preventing dielectric from leaking from tailpipe, between tail pipe bottom and cable, filling with sealant can prevent dielectric from leaking further.This utility model has that dielectric strength height, sealed bottom performance be good, the advantage of long service life.
