The syndeton of above-mentioned bus duct comprises two bus ducts and a connector, and the top of described connector is insulator, and bottom is conductor.
The method of attachment of above-mentioned bus duct is as follows: linked together by connector by two bus ducts, and key is that the top of described connector is insulator, and bottom is conductor; First by relative for the end of two bus ducts and close, and by the groove of the bottom of connector to quasi-conductor, then by the through hole of a bolt through two bus ducts, the end of bolt screws on nut, thus is furthered by two bus ducts; In the process that two bus ducts are close, the inclined-plane in line ball portion of bus duct and the top contact of connector, thus connector is pressed downward in the groove of electric conductor, realize the electrical connection of the corresponding electric conductor in two bus ducts.
Further, the inclined-plane in described line ball portion is provided with the draw-in groove being parallel to mounting groove, and when connection bus groove, the top of described connector is aimed at and snapped onto in the draw-in groove on the inclined-plane in described line ball portion.Above-mentioned draw-in groove can form location to connector, prevents connector from occurring tilting.
Further, be provided with transition gap between described line ball portion and the end face of bus duct body, described connector is up-small and down-big isosceles trapezoid tabular structure.When two bus ducts are furthered, the top of connector moves closer to transition gap, and after two bus ducts connections, the top of connector and the top board of bus duct body offset, and can not continue again to press down, such connector is not just utilize the inclined-plane in line ball portion to fix (contact point only has two), but utilizes the top board of bus duct body to fix (contact point is plane), substantially increases the stability of connector.
Further, described electric conductor is bent into cross section by conducting strip and forms for " M " shape structure, to ensure the elasticity of groove, thus enables groove be in clamping connection the bottom of part, realizes the reliable electrical connection of two electric conductors.
Bus duct structure of the present invention is simple, easy to connect, and can ensure after connecting that the electrical connection of the electric conductor in two bus ducts is reliable, has good practicality and commercial value.
