[0036] In order to solve the problem in the prior art that the disconnector wire of the lightning arrester is prone to breakage under strong wind conditions, the present application provides a connection tool and a lightning arrester having the same.

Among them, the first end of the first connection part 10 is used to connect with the arrester body, and the second connection part 20 is used to connect with the high-voltage line. The two ends of the first traction group are respectively connected to the first end of the first connection part 10 and the disconnector 30, and the first traction group includes a first wire assembly 40 and a first chain assembly 50 arranged at intervals, and the two ends of the first wire assembly 40 and the first chain assembly 50 are respectively connected to the first connection part 10 and the disconnector 30. The two ends of the second traction group are respectively connected to the second end of the second connection part 20 and the disconnector 30, and the second traction group includes a second wire assembly 60 and a second chain assembly 70 arranged at intervals, and the two ends of the second wire assembly 60 and the second chain assembly 70 are connected to the second connection part 20 and the disconnector 30. Among them, the length of the first chain assembly 50 is less than that of the first wire assembly 40, and the length of the second chain assembly 70 is less than that of the second wire assembly 60.
