    Abstract: A high-frequency coil pulling holes arrangement for producing multiple silicon cores in the technical field of high-frequency coil is provided. The running electric current can be made to spread generally uniformly around each pulling hole by the diversion effect of diffluent trough or diffluent trough and subsidiary electric current guiding holes by means of changing the positions of diffluent trough and assisted by C-shaped diffluent trough and subsidiary electric current guiding holes, and alternatively by means of providing interconnected diffluent trough between two pulling holes to form barbell-like part between pulling holes at the outer end of radial diffluent troughs. Because the electric current can more uniformly spread around each pulling hole assisted by diffluent trough, it is accomplished that the current is uniformly spread around pulling holes and consequently the appearance of low quality products can be diminished.
