Preferably, the aluminum stranded wires in the connecting piece 3 are used as current-carrying conductors and generally comprise 4-6 aluminum stranded wires, and the specific number and type of the aluminum stranded wires are determined by the maximum current carrying capacity of the pipe nuts. Under the condition that no earthquake occurs, namely when the combined hardware fitting is under a normal working condition, each aluminum stranded wire is S-shaped, so that two aluminum stranded wires are combined to form an 8-shaped cross structure, and two ends of each aluminum stranded wire are respectively connected with the tube bus 1 and the tube bus 5.
Preferably, taking the grading ring assembly 4 as an example (the structure of another grading ring assembly 2 is the same as that of the grading ring assembly 4), referring to fig. 2, fig. 2 is a schematic structural view of a grading ring assembly in a combined hardware fitting provided by an embodiment of the present invention; the grading ring assembly 4 comprises a first circular ring 41, a second circular ring 43 and a bracket 42 for fixing the first circular ring 41 and the second circular ring 43; wherein,
