Summary of the invention
The purpose of this utility model is to provide Stern tube seal reliable dry type outdoor terminal bottom one, with solve prior art dry type outdoor terminal tail pipe use self-adhesive tape seal cause poor sealing performance technical problem.
This utility model adopts the following technical scheme that a kind of dry type outdoor terminal, including support insulators, stress cone, silicon rubber umbrella skirt, support insulators is arranged on the outside of cable, silicon rubber umbrella skirt is arranged on the outside of support insulators, stress cone is positioned at the bottom of support insulators, the top of silicon rubber umbrella skirt is provided with overhead guard, the top of overhead guard is provided with wire leading-out clamp, the periphery of the bottom of support insulators is provided with afflux sealing ring, periphery below support insulators is provided with tail pipe, the upper and lower of described tail pipe is respectively equipped with lip ring, the lip ring sealed envelope on tail pipe top is in tail pipe upper end, support insulators lower end and the outside of afflux sealing ring upper end, the lip ring sealed envelope of tail pipe bottom outside of end cable under tail pipe lower end and tail pipe.
The integrated structure that described lip ring is made up of rubber.
Described lip ring is by poured with epoxy resin molding.
Described silicon rubber umbrella skirt includes big full skirt spaced apart and little full skirt.
The bottom of described stress cone is provided with the centring ring that a circle fixed cover is located on cable.
It is provided with sealing ring between described wire leading-out clamp and overhead guard.
The beneficial effects of the utility model: this utility model is respectively provided with lip ring in tail pipe upper and lower, utilize lip ring respectively by the peripheral seal of tail pipe upper and lower, support insulators and afflux sealing ring are by the lip ring sealed envelope on top, the cable of tail pipe bottom is sealed by the lip ring of bottom and surrounds, lip ring is difficult to be occurred puncturing and problem of aging, therefore considerably increases the sealing property of this utility model dry type outdoor terminal.
Preferably, the integral annular sealing member using rubber to make has good springiness, easily installation, the advantage of length in service life.
Preferably, the lip ring of poured with epoxy resin molding has advantage durable, the most easy to crack.
Preferably, spaced size full skirt can strengthen the anti-pollution characteristic of outdoor terminal.
Preferably, centring ring not only makes stress cone be easily installed location, it is also possible to upwards hold out against stress cone, it is ensured that the interfacial pressure of stress cone, prevents stress cone from relaxing and causes interfacial pressure to decline.
Preferably, the sealing ring between wire leading-out clamp and overhead guard can increase the sealing property at dry type outdoor terminal top.
