Technical solution: technical solution used by the utility model is a kind of such, bus duct of ease of assembly, including U-shaped shell, the dust cover for being connected in U-shaped shell nozzle end are staggeredly disposed on the U-shaped shell left and right side inner wall more A copper bar clamping groove, is connected with insulator in the copper bar clamping groove, and inserted with conductor in the insulator, the conductor is Integrally formed detour U-shaped structure conductor, the detour U-shaped structure conductor is by U-shaped structure and by the top of U-shaped structure two sides Bend inwards to form two vertical edges composition, two vertical edges and U-shaped structure two sides are arc transition, the conductor it is U-shaped Structure two sides outer wall lower part, which is recessed inwardly, is formed with recess, and the insulator is to match with the U-shaped structure shape of conductor U-shaped insulator, insulator two sides upper inside wall, which outwardly protrudes, is formed with protrusion.

For convenience U-shaped shell and dust cover installation, it is preferable that U-shaped shell left and right side walls open end to A pair of of raised line has inside been protruded out, a pair of of T-type item, the horizontal stripe and raised line of the T-type item are symmetrically arranged at U-shaped shell inner opening end Parallel, the vertical bar of T-type item is connected with copper bar clamping groove；The dust cover both ends are opposite with raised line and T-type item respectively It answers and is symmetrically arranged with a pair of of clamping joint at position, the clamping joint includes card slot and the guiding surface group that is connected with card slot top surface At the guiding surface and card slot top surface are at an acute angle, when installation, only need to gently pat in i.e. embeddable U-shaped shell, installation is torn open It unloads conveniently.

Preferably, the raised line, T-type item and U-shaped shell are integrally formed.

Preferably, the guiding surface and card slot top surface are in 30-60 °.

Preferably, the insulator uses PC material.

Preferably, a plurality of strengthening rib strip has been protruded outward on the U-shaped shell left and right side walls outer wall.

The utility model has the advantages that

1, the utility model bus duct is designed as guide tracked, can be from any point contact electricity getting, and user can be according to electric position Jack box position is altered or modified in demand at any time, brings great convenience to user, in addition between row and row phase distance compared with Greatly, safety is higher.

2, guide tracked bus-bars conductor uses detour U-shaped structure, and insulating part uses special matched U-shaped structure；Conductor it is U-shaped Structure two sides outer wall lower part, which is recessed inwardly, is formed with recess, increases the elasticity of conductor, while on the inner wall of insulator two sides Portion, which outwardly protrudes, is formed with protrusion, so that conductor is easily inserted directly into U-shaped insulating part, both ends are insulated after spacer block blocks, then by its It is easy to operate in whole insertion housing guide grooves, assembly can be completed without particular device.
