Description
Technical field
The utility model relates to the conductor connection area, is specially connector and jockey that a kind of conductor connects usefulness, is widely used in the processes such as electric power, power construction installation, electric wire manufacturing, to the isometrical or reducing connection of cable conductor, copper, the naked twisted wire of aluminium.
Background technology
Along with the Chinese national economy high speed development, the big and medium-sized cities power consumption equipment increases, and a very fast developing stage has also appearred in the application of power cable.Because the urban electricity supply circuit is long, the main line cross-sectional area of conductor is large, the power cable conductor tie point is increased, yet new challenge has been proposed also the cable conductor connected mode, cable connection point is the important component part of power cable, it also is the weak link of whole cable, its failure rate accounts for about 60% of whole cable fault, and major part appears on the conductor core wire tie point in the cable fault, becoming the large safety problem of one in the cable power supply system so conductor connects quality, also is an important step of cable security power supply.As deal with improperly, time one is long, the phenomenons such as becoming flexible can appear in the conductor tie point, loose contact, heating oxidation, and accident can be short-circuited when serious, cause power consumption equipment normally not move, bring potential safety hazard or cause fire incident for enterprises and institutions or residential electricity consumption.
Because above-mentioned situation by the understanding that in the past few years power cable is connected, is developed a kind of novel cable connected mode, to be applicable to the development in science and technology needs of society.
China is connected with corresponding national Specification to power cable conductor, GB/T14315-2008 " power cable conductor with crimp type copper, aluminum connecting terminal is connected with tube connector and GB/T9327-2008 " rated voltage 35kV (Um=40.5kV) and following power cable conductor usefulness compression joint type are connected gold utensil test method and requirement with mechanical type ".This standard has been made detailed regulation to the connection of power cable conductor, but also has a lot of problems with crimp type copper, aluminium connecting tubes bonding conductor.As:
A, because with the crimping of hexagon mould, after the crimping tube connector surface not rounding, discontinuity distortion, crooked, corner angle are arranged, tensile strength is low;
Local conductor is impaired serious after b, the crimping, and conductor contacts not tight with tube connector, and resistance value is large;
Easily loosening, the heating oxidation of c, conductor and tube connector, broken string;
D, non-uniform electric cause the insulation breakdown short circuit easily;
E, in order to guarantee conductor resistance value, also to be coated with conducting resinl in conductive surface and the tube connector before the crimping, cable cost is increased;
After f, the tube connector crimping, the tube connector size is uncontrollable different, has a strong impact on the cable quality of connection.
At present, China generally uses tube connector, the cable conductor two ends are inserted in the tube connector, with crimping tool (as: hand-hydraulic Press Plier and electric hydaulic Press Plier) several times sectional crimping on tube connector, tube connector is pressed on the cable core, because the mould on the crimping jaw is hexagon, so one section one section of the tie point after being crimped leaves the hexagon vestige, cause the rough corner angle of tube connector outstanding, simultaneously under the effect of external force, the distortion that is badly damaged of tube connector inner wire part, contact not closely between tube connector and the conductor, the local area excesssive gap causes mechanical strength, conductor resistance is uncontrollable, because the hexagon vestige is left on the tube connector surface, so non-uniform electric.
