The core wire assembly 1 can be used to transmit signals or electric energy. For example, as shown in FIG. 3, the core wire assembly 1 includes a core wire 11 and a core wire insulation layer 12 wrapped around the core wire 11. The shielding layer 2 is sleeved outside the core wire assembly 1, and the material of the shielding layer 2 can be a metal material to be able to play a shielding role to ensure the transmission effect of the core wire assembly 1.

In an embodiment, a plurality of hollow holes 21 on the shielding layer 2 are arranged in an array on the shielding layer 2, or, as shown in FIG. 3, a plurality of hollow holes 21 on the shielding layer 2 are spirally arranged on the shielding layer 2. cloth. Both of the two arrangements of the hollow holes 21 have high uniformity, which in turn enables the distribution of the plurality of heat dissipation paste blocks 41 to be more uniform, and can improve the heat dissipation effect after the heat dissipation paste block 41 is melted.
