[0024] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0025] The power signal line of the voice core board includes a cable sleeve 1, a power line body 2 and a signal line body 3 are respectively arranged inside the cable sleeve 1, a shielding layer 4 is arranged on the outside of the power line body 2 and the signal line body 3, and a wear-resistant mechanism 5 is arranged on the outside of the cable sleeve 1;

[0026] Specifically, a filling layer is provided inside the cable sheath 1;

[0027] In this embodiment, the filling layer is mainly used to wrap the power cord body 2 and the signal cord body 3, thereby increasing the friction contact force between the power cord body 2, the signal cord body 3 and the cable sheath 1, and preventing the power cord body 2, the signal cord body 3 from separating from the cable sheath 1.

[0028] Specifically, the shielding layer 4 is respectively attached and wound around the outer surfaces of the power line body 2 and the signal line body 3, and is made of double-sided plastic-coated aluminum tape;

[0029] In this embodiment, the shielding layer 4 can effectively intercept external electromagnetic interference, ensure the integrity of signal transmission of the power line body 2 and the signal line body 3, and facilitate the voice core board to work better.

[0030] Specifically, the cable sleeve 1 is made of high-density polyethylene material;

[0031] In this embodiment, the insulation performance of the cable sheath 1 can be improved by providing high-density polyethylene.

[0032] In this embodiment, please refer to Figure 1 and Figure 3 The wear-resistant mechanism 5 includes a silicone layer 501, an inner sheath 502 and a braided layer 503 which are respectively sleeved on the outer surface of the cable sheath 1;

[0033] Specifically, the outer surface of the silicone layer 501 contacts the inner side of the inner sheath 502, and the outer surface of the inner sheath 502 contacts the inner wall of the braided layer 503, and the braided layer 503 is formed by integrally braiding polyester fibers;

[0034] In this embodiment, the silicone layer 501 is mainly used to form a close contact with the outer surface of the cable sheath 1, thereby ensuring the installation effect of the inner sheath 502, and the braided layer 503 plays a role in wear-resistant protection of the cable sheath 1 through the wrinkle resistance and friction resistance of the polyester fiber, thereby meeting the use requirements of the power signal line.

[0035] The working process of the utility model: when the power signal line of the voice core board is used, the power signal line is connected to the input end of the voice core board, and then one end of the shielding layer 4 is grounded. Under the action of the shielding layer 4, interference signals are prevented from entering the power line body 2 and the signal line body 3, and at the same time, the internal signals are prevented from radiating out, thereby ensuring the normal signal transmission of the power line body 2 and the signal line body 3. Furthermore, under the action of the silicone layer 501, the inner sheath 502 and the braided layer 503 are tightly sheathed on the outer surface of the cable sheath 1, and the braided layer 503 has excellent wear resistance, thereby playing a role of wear-resistant protection for the cable sheath 1, meeting the needs of users.
