The shorting assembly of claim 1, wherein said inner protrusion has an inner male thread thereon and said outer protrusion has an outer male thread thereon; the male screw thread is in screwing fit with the female screw thread to pass through the female screw thread, so that the electric connecting rod is assembled in the conductive sleeve.
3. The shorting assembly of claim 1, wherein the electrical connection rod has a polished rod segment connected between the abutment end and the outer flange;
the end face, facing away from the abutting end, of the inner convex part is a first end face, and the end face, facing towards the abutting end, of the conductive sleeve is a second end face; in the axial direction of the conductive sleeve, the length of the polish rod section is greater than or equal to the distance between the first end face and the second end face.
4. A shorting assembly as claimed in claim 3 wherein the conductive sleeve has a large diameter barrel section and a small diameter barrel section arranged in an axial direction thereof, the small diameter barrel section having an inner diameter smaller than the inner diameter of the large diameter barrel section, the inward projection being located on the small diameter barrel section;
the polish rod section is provided with a first rod section and a second rod section, and the second rod section is connected between the first rod section and the outer convex part; the outer diameter of the second rod section is smaller than that of the first rod section, the outer diameter of the second rod section is smaller than or equal to that of the small-diameter cylinder section, and the outer diameter of the first rod section is smaller than or equal to that of the large-diameter cylinder section, so that the electric connecting rod can axially move along the conductive sleeve.
5. The shorting assembly of claim 1, wherein the abutting end further has a conductive portion, and wherein the insulating operation portion is connected to a side of the conductive portion facing away from the outer flange in an axial direction of the conductive sleeve, and wherein the insulating operation portion wraps at least a portion of the conductive portion.
6. The shorting assembly of claim 5, wherein at least a portion of said conductive portion is capable of extending into said through bore to abut said conductive sleeve in an axial direction of said conductive sleeve, said insulating handle portion being in clearance fit with said insulating housing.
7. The shorting assembly of claim 5, wherein the insulating handle portion has anti-slip patterns disposed on an outer peripheral surface thereof.
8. A shorting assembly as claimed in any one of claims 1 to 7 wherein the electrical connector bar further has a connection end connected to a side of the outer flange facing away from the abutment end, the connection end being for connection with a current terminal.
9. A shorting assembly as claimed in any one of claims 1 to 7 wherein the insulating housing has an outlet for securing the shorting wire, the outlet communicating with the through bore, the outlet being oriented parallel to the axial direction of the conductive sleeve.
10. A shorting device comprising at least two shorting assemblies as recited in any one of claims 1 to 9, and further comprising a shorting wire connecting at least two of the shorting assemblies, the shorting wire electrically connected to the electrical connection bars.
