Abstract

The invention provides a jack protection cover for a dense type bus grooves, belonging to the field of electrics. The defect of partial expansion caused by that the conventional jack protection cover for the dense type bus grooves transversely protrudes is overcome. The jack protection cover comprises a bar-shaped cover body, jacks which are distributed on the cover body and are used for containing bus pins and wafer type plugs by passing through the cover body, and a middle beam for dividing the jacks into two sockets. According to the improvement, the jacks are vertically arranged along the cover body, the jacks of the plugs for connecting buses at the both sides in the bus grooves or the buses adjacent to the buses at the both sides deviate toward the middle part of the cover body from the corresponding buses, grooves for containing the transverse folding parts of the pins are arranged at one ends of the deviated jacks which face to the bus, and the jacks of the other buses align to the corresponding buses. The jack protection cover for the dense type bus grooves provided by the invention has the positive effects as follows: in a condition of not influencing insulating properties and convenience for operation, a transverse size of the protection cover is reduced, and the jack protection cover is as wide as the bus grooves, thereby overcoming the defects that the partial occupied space of the bus grooves is large caused by that the conventional jack protection cover for the dense type bus grooves protrudes the both sides of the bus grooves so that the meanings of the dense buses is reduced.

Description

A kind of concentration bus duct jack guard shield

Technical field

The invention belongs to electric field, be specifically related to bus current and draw the splicing interface member.

Background technology

In the past, the bus in the bus duct all separated installation each other.The bus duct lateral dimension is bigger; Each phase bus current at the electric current place of drawing plug laterally between and between the bus plug in the bus group outside and bus box wall, enough distances are arranged all; Plug transversely arranged unaffected on bus duct; So the electric current leading foot that is embedded on the bus all is provided with the bus isoplanar, the jack longitudinal midline on the electric current extraction location insulating shield all can be located on the bus thickness symmetry interface one by one.Along with the development of material, manufacturing technology in the electric field and dwindle the bus duct volume and reduce with material and the effect that takes up space less to obtain; The concentration bus duct of bus clamping heat insulating lamella structure is being made more and more and is being used; Because the minimizing of concentration bus duct lateral dimension; The bus hypotelorism is arranged down folder bus pin and the electric current that needs enough insulation spacings is drawn plug, haves no alternative but through with the pin lengthening and strengthen the phase mutual edge distance from the bus duct external part; Connected structure by non-dense set type bus duct is provided with the jack guard shield again; This structure forms the part and expands ledge on concentration bus duct, reduced the advantage that concentration bus duct takes up space less to a certain extent.

Summary of the invention

The purpose of this invention is to provide a kind of concentration bus duct jack guard shield, be used for the insulating protection that the bus duct electric current is drawn plug position, overcome existing concentration bus duct protrusion bus duct border, form local shortcoming of expanding.

The present invention includes square-section strip insulating material cover body; Be distributed on the cover body; See through the jack that cover body holds bus pin and wafer type plug, jack external port place is divided into the central sill that is used to block conductor pins of two sockets with jack, and the improvement of being done is: said jack is vertically arranged along cover body; The vertical consistency of the vertical and cover body of jack; Be used for two side bus in the connection bus groove or depart from pairing bus with the jack of the plug of the adjacent bus of two side bus to the cover body middle part, the jack of corresponding bus has and holds pin cross break groove partly towards an end of bus departing from; All the other bus currents are drawn jack and the pairing bus of plug on guard shield and are aligned.

Use with actual for ease of the processing of jack guard shield, the displacement jack and with the jack of the adjacent bus of outer side bus that is used to peg graft vertically point-blank,

Good effect of the present invention is: under the situation that does not influence insulation property and handled easily; Shrink the lateral dimension of guard shield; Realized the wide of jack guard shield with bus duct; Eliminated existing concentration bus duct jack guard shield protrusion bus duct both sides, caused the occupy-place of bus duct local space big, made the intensive meaning of bus by the deficiency of discount.

Figure 12 is bus and a pin configuration graph of a relation in the bus duct.

Consult Fig. 1-Figure 11; The present invention includes square-section strip insulating material cover body 1; On the cover body of Fig. 1; Vertically arrange by bus phase settings order from top to bottom and see through jack 2-PE, 2-N, 2-A, 2-C, the 2-B that cover body holds bus pin and wafer type plug, jack external port place with jack be divided into two sockets the central sill 3 that is used to block conductor pins, jack is vertically arranged along cover body; Jack vertically with the vertical consistency of cover body, be used in the connection bus groove on the left of the jack 2-A of A phase bus plug depart from bus A be located at B mutually bus align (overlapping) position.The jack 2-PE that connects the plug of right side PE phase departs from bus PE and is located at the bus aligned position mutually with N, and the jack 2-N that connects the plug of N phase departs from bus N the bus aligned position mutually with C is set, and jack 2-C, 2-B align bus separately to the B phase mutually with C.

Consult Fig. 2, Fig. 3, Fig. 4,, the groove 4PE, 4N, the 4A that hold pin cross break part arranged at the jack 2-PE that departs from bus separately, 2-N, 2-A a end towards bus,

Consulting Figure 12, is A, B, C, N, PE setting bus phase sequence from left to right, and vertically putting in order of pin 5 is 5B, 5C, 5A, 5N, 5PE.Wherein, pin 5A is bent to (isoplanar) directly over the B phase bus, pin 5N be bent to C mutually directly over, pin 5PE be bent to C and N mutually between.
