Abstract

The utility model relates to a category 6 shielding double-airplane vertical packaging forming die, belonging to the data cable vertical packaging processing technology field. The category 6 shielding double-airplane vertical packaging forming die is composed of a forming die body, an upper airplane die, a metal latch, and a lower airplane die, wherein the lower airplane die and the forming die body are fixed via the metal latch; the upper airplane die is arranged above the lower airplane die; and the upper airplane die and the lower airplane die are isolated via the metal latch. As the winding packing technology is replaced by the vertical packing technology and both the aluminium foil vertical packing and the polyester belt vertical packing are simultaneously carried out while vertically packing a cable core sheath, the category 6 shielding double-airplane vertical packaging forming die saves the cost of the raw material. Moreover, after vertical packaging, the diameter of the cable core becomes smaller and the external diameter of the sheath is decreased, thereby making the structure of the cable core more even and the performance of the cable core more stable. Particularly, the detecting data of the key parameters of the attenuation, the impedance, and the structure return loss are better than the standard value, thereby largely improving the qualified rate and overcoming the unbalanced influence of conventional winding packing upon the cable structure.
