Core group.

As mentioned above, the configuration of the plurality of first core groups and the plurality of second core groups in the first transmission group and the second transmission group enables the cable structure of this creation to be stable in designs of different lengths. Telegraph transmission.

In order to explain in detail the technical content, structural characteristics, achieved goals, and effects of this creation, the following examples are given in conjunction with the drawings to explain in detail.

Please refer to the first figure. The cable structure 100 of this creation includes at least one stuffing member 1, a first transmission group 2, a first shielding layer 3, a second transmission group 4, a second shielding layer 5, and a braid. Layer 6 and an insulating sheath 7.

The first transmission group 2 is coated on the outside of the packing member 1, the first shielding layer 3 is coated on the outside of the first transmission group 2, and the second transmission group 4 is covered on the first shielding layer. 3, the second shielding layer 5 covers the second transmission group 4, the braided layer 6 covers the second shielding layer 5, and the insulating sheath 7 covers the Beyond woven layer 6.

The first transmission group 2 and the second transmission group 4 are composed of a plurality of first core group 8 and a plurality of second core group 9, and the number and configuration of the first core group 8 and the second core group 9 may be different according to different The need to make adjustments is not limited to the number disclosed in this embodiment, and the diameters of the first core group 8 and the second core group 9 are different.

In this embodiment, the first core wire group 8 is composed of at least one first conductive wire 81 and at least one first ground wire 82, and the second core wire group 9 is composed of at least one second conductive wire 91 and at least one second wire. The ground wire 92 is composed of wire diameters of the first conductive wire 81 and the first ground wire 82 different from those of the second conductive wire 91 and the second ground wire 92. In this embodiment, the first core wire group has two of the first conductive wires 81 and one of the first ground wires 82, and the second core wire group 9 has two of the second conductive wires 91 and one A second ground wire 92, the first transmission group 2 is provided with four first core wire groups 8 and two second core wire groups 9, and the second transmission group 4 is provided with ten first core wire groups 8.
