A connecting cable group 2 is provided at the center of the shielded cable body 1, and the shielding layer 4 is wrapped around the outside of the connecting cable group 2. Its arrangement improves the strong anti-interference shielding effect of the twisted shielded pair cable, and the gap between the shielding layer 4 and the connecting cable group 2 is filled with the filler 3, which plays a filling role between the connecting cable group 2 and the shielding layer 4, and effectively copes with the mutual friction between the connecting cable groups 2 under the conditions of rolling, twisting, etc., thereby affecting the normal service life of the twisted pair shielded cable, and the protective layer 5 is wrapped around the outer wall of the shielding layer 4 to play a protective role.

[0020] In this embodiment, the connecting wire group 2 is formed by winding multiple connecting wires 6, and through the covering of the shielding layer 4 and the protective layer 5, a tidy connecting wire 6 can be realized, further ensuring the strength of the twisted shielded pair cable and facilitating the subsequent installation and insertion of the twisted shielded pair cable.

[0021] In this embodiment, the connecting wire 6 includes a wire core 61 and an inner protective layer 62 . The wire core 61 is arranged at the center of the connecting wire 6 . The inner protective layer 62 is wrapped around the outer wall of the wire core 61 , and is effectively arranged to protect the safety of the use of the wire core 61 .

[0022] In this embodiment, the protective layer 5 includes an anti-wear coating 54, a braided layer 52, an outer protective layer 53 and an isolation layer 51. The isolation layer 51 is wrapped around the outer wall of the shielding layer 4. This structural design plays an isolating role for the shielding layer 4, protects the shielding layer 4, and prevents the shielding layer 4 from being damaged. The braided layer 52 is wrapped around the outer wall of the isolation layer 51. Its structural design improves the bending strength of the twisted pair shielded cable, and has the characteristics of repeated bending. The outer protective layer 53 is wrapped around the outer wall of the braided layer 52. This structural design plays a protective role. The anti-wear coating 54 is wrapped around the outer wall of the outer protective layer 53.

[0023] In this embodiment, the braided layer 52 is braided by a plurality of silver-plated copper wires. This structure improves the bending resistance of the twisted-pair shielded cable.
