Mutually separate direction extends, and since the length of contact tube is small compared with the big rigidity of long and amount of deflection, therefore stretches out the part outside fuse both ends
It can generate hanging, cause when carrying out horizontal assembly since the effect of gravity is relatively difficult to guarantee hollow combined insulator, fuse and leads
Fulgurite is in horizontal concentric position always, and since the outer diameter of fuse and the internal diameter of hollow combined insulator are very close, in core
Gap between the two is very small when son is installed in hollow combined insulator, if cannot keep fuse and hollow combined insulator
Between concentric position, then be easy to collide with hollow combined insulator when installing fuse, it is easy to be to fuse and hollow multiple
Insulator is closed to cause to damage；In addition sagging product electric field, thermal field, the force distribution of will lead at the both ends of contact tube is uneven, answers
Power is concentrated, current-carrying and sealing performance are unreliable and other issues, to influence product quality.
And in the prior art, for some big molded cannulas, usually skilled operator is using visually observation when assembly
Mode by contact tube centered assembling.Using this centered assembling mode, error is very big, needs to dismantle tune repeatedly after having assembly
Whole problem.
