Description
Technical field
This utility model relates to a kind of porcelain bushing type outdoor terminal, belongs to cable accessory technical field.
Background technology
Outdoor terminal is a kind of terminal connector in cable accessory, due to the advantage that porcelain bushing type outdoor terminal has mechanical strength height, creep age distance is big, anti-pollution characteristic is good, can be widely used in the area of bad environments.In prior art, dielectric is filled in the inside of porcelain bushing type outdoor terminal, and in order to make to realize between cable and tail pipe sealing, winding of band-type material on cable, the strip material being entwined 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 dielectric passes through strip material and oozes out.And, strip material is easily subject to stab, and also results in dielectric leakage.Therefore, there is the technical problem that sealed bottom sealing structure performance is bad, dielectric easily leaks in this cable accessory of the prior art, has very big potential safety hazard.
Publication number is CN202978197U, publication date be June 5 in 2013 day, be called that the utility model patent of " a kind of have the outdoor terminal reliably sealing structure " discloses a kind of outdoor terminal, by warding off lead-tight between tail pipe and the cable of this outdoor terminal, at tail pipe with ward off and be provided with sealing structure between lead, increase an impervious barrier sealing structure place.By increasing by one layer of impervious barrier, it is possible to effectively submit sealing property to.But, lead-tight is warded off in use to be needed to be subjected to, and adds outdoor terminal installation difficulty；And the double-deck tetrafluoroethene self-adhesive tape that the impervious barrier of this outdoor terminal adopts, this self-adhesive tape yet suffers from easily being punctured the easily aging problem that cause leakage short in service life.
Summary of the invention
The purpose of this utility model is in that to provide a kind of simple installation, long service life, the reliable porcelain bushing type outdoor terminal of sealing, and the outdoor terminal to solve prior art installs the technical problem of trouble and poor sealing performance.
This utility model adopts the following technical scheme that a kind of porcelain bushing type outdoor terminal, including porcelain bushing shell, the top of porcelain bushing shell is connected to wire leading-out clamp, bottom is connected to tail pipe, middle part in porcelain bushing shell is provided with the stress cone being arranged on cable, dielectric it is filled with inside porcelain bushing shell, what described porcelain bushing shell and tail pipe connected is provided externally with base, base is connected with support insulator, it is positioned at tail pipe top position in described porcelain bushing shell and is provided with cable seal structure, described cable seal structure is the lip ring being set on cable periphery, the upper end of described tail pipe is sealingly disposed in the position between the periphery of cable and lip ring, the outer surface of described tail pipe upper end and the inner surface of lip ring seal and coordinate.
Described lip ring is made up of rubber.
Described dielectric is silicone oil.
The outer surface that described stress cone contacts with dielectric is provided with stress cone protection set.
There is outside described porcelain bushing shell 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: this utility model arranges lip ring on cable periphery, utilize the part that lip ring hermetically-sealed cable contacts with tail pipe, owing to tail pipe upper end is the position being sealingly fitted between cable and lip ring, therefore thoroughly stop the probability that dielectric leaks from tail pipe.Owing to sealing structure of the present utility model is the monolithic construction adopting lip ring, has only to during installation be enclosed within cable sealing member, then tail pipe upper end is inserted into the position between sealing member and cable.This utility model good seal performance, installs very easy, long service life, and puncturing and aging problem not easily occurs in sealing member.
Preferably, this utility model adopts the advantage that the lip ring that rubber is made has good springiness, easily installation, long service life.
Preferably, stress cone protection set can make stress cone and dielectric keep apart, it is to avoid dielectric and stress cone compatible phenomenon, moreover it is possible to keep the pressure between stress cone and cable, thus ensureing dielectric strength.
Preferably, the outer spaced size full skirt of porcelain bushing shell 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.
The structure of a kind of embodiment of this utility model is as shown in Figure 1, the porcelain bushing type outdoor terminal of the present embodiment includes porcelain bushing shell 2, porcelain bushing shell 2 is outside has big full skirt 4-1 spaced apart and little full skirt 4-2, and spaced size full skirt can strengthen the anti-pollution characteristic of outdoor terminal.The top of porcelain bushing shell 2 is connected to wire leading-out clamp 1, bottom is connected to tail pipe 6; tail pipe 6 is provided externally with tail pipe protection set 11; middle part in porcelain bushing shell 2 is provided with the stress cone 5 being arranged on cable; porcelain bushing shell 2 is internal is filled with dielectric 3; dielectric 3 is silicone oil, and the outer surface that stress cone 5 contacts with dielectric 3 is provided with stress cone protection set 10.Stress cone protection set 10 can make stress cone and dielectric keep apart, it is to avoid dielectric and the compatible phenomenon of stress cone, moreover it is possible to keep the pressure between stress cone and cable, thus ensureing dielectric strength.What described porcelain bushing shell 2 and tail pipe 6 connected is provided externally with base 7, base 7 is connected with support insulator 8, it is positioned at tail pipe 2 top position in described porcelain bushing shell 2 and is provided with cable seal structure, described cable seal structure is the lip ring 9 being set on cable periphery, lip ring 9 is made up of rubber, the upper end of described tail pipe 6 is sealingly disposed in the position between the periphery of cable and lip ring 9, and the outer surface of described tail pipe 6 upper end and the inner surface of lip ring 9 seal and coordinate.
