Leakage coaxial cable sizing drawing die utensil

The utility model discloses a leakage coaxial cable sizing drawing die utensil, include mould body and the chamber of drawing of lining up the mould body, the chamber of drawing constitutes by the inlet region that switches on in proper order and sizing district, the inlet region is round platform shape cavity, angle more than or equal to 10 and less than or equal to 60 are drawn for drawing the angle to the generating line of round platform shape cavity and the round platform shape cavity contained angle that the axis becomes, the right -hand member opening of inlet region is greater than the left end opening, the left end opening and the sizing district right -hand member opening of inlet region switch on, the sizing distinguishes that to be the diameter that cylindrical cavity and sizing distinguished the same with inlet region left end open -ended diameter, the roughness ra of inlet region internal surface is 1.6, and the roughness ra of sizing district internal surface is 0.8. The utility model discloses need not to make the with lubricator, stopped the copper strips simultaneously in the signal microleakage of commissure phenomenon, can also guarantee the outer conductor and cable insulation sinle silk in close contact with of cable, prevent that the outer conductor from kick -backing and outer conductor laminating tension makes the destruction of insulation.
