Abstract
The utility model relates to a bus slot connector which belongs to the technical field of distribution. The bus slot connector provided by the utility model comprises an insulating bolt, an upper cover plate, a lower cover plate, a connecting copper bar which is conductively connected with phase conductors of bus slots on both ends and an insulating isolation plate which isolates the connecting copper bar. Through the insulating bolt, the connecting copper bar and the insulating isolation plate are clipped between upper and lower cover plates. The insulating isolation plate is provided with an annular first boss. A screw hole is at the middle part of the first boss, wherein the insulating bolt passes through the screw hole. The connecting copper bar is sheathed on the outer side of the first boss. According to the utility model, enough creepage distance is ensured; the installation is convenient; and small contact resistance can be kept.
Description
Technical field
The utility model relates to a kind of connector, and especially a kind of bus-duct connector, belongs to distribution technique field.
Background technology
Bus duct system is an efficient power distribution equipment of carrying electric current, especially the needs that adapted to more and more higher building and large-scale plant economical rationality distribution, therefore be widely used in being connected of low-voltage distribution panel and large and medium-sized load, as modern workshop, factory building and skyscraper, be particularly suitable for the workshop that product is changeable, equipment is intensive; The connection copper bar of bus-duct connector of the prior art is generally surface plate, makes the contact of connector and radiating effect poor, has affected the switching performance of bus duct, thereby greatly reduces the fail safe of bus duct.
Utility model content
The purpose of this utility model is: the problem existing for above-mentioned prior art, proposes a kind ofly can guarantee enough creepage distances, easy for installation and can keep the bus-duct connector of less contact resistance.
In order to reach above object, a kind of bus-duct connector of the present utility model, comprise that insulated bolt, upper cover plate, lower cover, conduction connect the connection copper bar and the isolated insulating barrier that is connected copper bar of two ends bus duct phase conductor, described insulated bolt is clipped in described connection copper bar and insulating barrier in the middle of upper and lower cover plate, on described insulating barrier, be provided with the first boss of annular, the screw of the middle part of described the first boss for passing through for insulated bolt, described connection copper bar is socketed in the outside of described the first boss.
Preferred version of the present utility model is:
Further, the one side that connection copper bar contacts with bus duct phase conductor is provided with two rectangular fins, cooperatively interacts and form respectively two slots that insert for phase conductor between the rectangular fin of two described connection copper bars.
Further, be provided with the triangular groove of strip on the outer wall of the first boss, the inwall of described connection copper bar trepanning is provided with the triangle fin angle matching with described triangular groove.
Further, connect the position contacting with phase conductor on copper bar and be provided with open slot.
Further, insulated bolt comprises stud and insulating sleeve, and described insulating sleeve is closely enclosed within on the outer wall of described stud through the bolt hole of described insulating barrier.
Further, upper cover plate and lower cover are separately fixed on the cell body of bus duct, and the two ends of described stud clamp upper cover plate and lower cover by nut, are also lined with butterfly gasket between upper and lower cover plate and nut.
The utility model beneficial effect is: 1. the utility model guarantees enough creepage distances by the first boss of insulating barrier and the size of increasing conducting copper mesopore, the setting of triangle fin angle and triangular groove is to have solved connection copper bar and insulating barrier installation orientation problem, has also guaranteed enough creepage distances simultaneously, 2. connect the slot space that the rectangular fin on copper bar forms each other, facilitated the insertion of phase conductor to install and location, 3. in order to stop the temperature of contact surface to rise under normal and emergency, contact area should be enough large, no matter enough large real contact area is provided, is initially, after still working over a long time, degenerates, still remain with contact (area) pattern, guarantee that junction can be not overheated, bolt connects example and shows, by changing junction design, can strengthen contact area (Boychenko, V.I. and Dzektser, N., Busbar Connections, Energiya, Leningrad, 1978.), on connection copper bar, slot, the real contact area ratio that can make to connect does not increase 1.5-1.7 doubly while there is no opening, the contact resistance ratio of slotted bindiny mechanism does not have the low 30%-40% of slotted contact resistance, when carrying out current cycle test, its mechanics and electric property are also more stable, the beneficial effect that otch connects copper bar comes from being uniformly distributed of contact, and expanded contact area, to reach minimum contact resistance and the temperature rise of minimum junction.
