Description
Technical field
The utility model relates to electrical equipment technical field, is specifically related to a kind of cold-shrink cable terminal.
Background technology
Along with the fast development of Chinese Urbanization, deepening continuously of power grid construction and transformation, crosslinked cable has been widely used in overhead transmission line and has been changed into ground, newly-built substation outlet etc.Cable terminal is assembled to cable line end in order to ensure the electrical connection with other power consumption equipments of electrical network, and a kind of device being provided as conductive cable cores insulation extraction, evenly cable end piece electric field, increasing creepage distance, prevent cable water tree from being formed.The manufacture level of cable terminal and quality, will directly have influence on the useful life of cable.But there is the defect of unstable properties, sealing effectiveness difference in existing cold-shrink cable terminal.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides that a kind of structure is simple, the reliable cold-shrink cable terminal of good sealing effect, performance safety.
For achieving the above object, the utility model adopts a kind of cold-shrink cable terminal, comprise cable, be wrapped in the terminal body on the top of cable, the periphery wall of described terminal body is provided with the equally distributed full skirt in multiple interval, and be provided with stress cone in the inwall of the bottom of terminal body, described stress cone is for being trumpet-shaped conductive silicon rubber part, and described stress cone is wrapped in the copper shield belt of cable, on semiconductive shielding layer, in described terminal body, corresponding stress cone lower end is provided with the shrinkage protecting pipe be wrapped on the copper shield belt of cable, ground connection braid over braid is provided with between described shrinkage protecting pipe and the copper shield belt of cable, the upper end of described ground connection braid over braid is fixed on the copper shield belt of cable by constant force spring, and the lower end of ground connection braid over braid extends towards extreme direction under shrinkage protecting pipe and is exposed at outside shrinkage protecting pipe.
The beneficial effect of said structure is: this cold-shrink cable terminal by being provided with stress cone in terminal body, this stress cone adopts Conductive silicon rubber material to make, this stress cone can overlap well with the copper shield belt of cable, semiconductive shielding layer, thus farthest can evacuate electric field stress, electric field homogenizing near the screen making cable, stop partial discharge to occur, extend the useful life of cable.And this cold-shrink cable terminal has structure is simple, performance safety is stable advantage.
Especially, the constant force spring place in described shrinkage protecting pipe described in correspondence is filled with water-tight glue.By being filled with water-tight glue at constant force spring place, thus improve the sealing property of this cold-shrink cable terminal.
Accompanying drawing explanation
