Description

Technical Field

[0032] In this embodiment, the plurality of first core wire bodies 411 are circumferentially arranged around the inner peripheral wall of the wire outer sheath 100, so that the wire outer sheath 100 is circumferentially covered around the first core wire layer 410. The plurality of second core wire bodies 421 are circumferentially arranged around the inner peripheral wall of the first core wire layer 410, so that the first core wire layer 410 is circumferentially covered around the second core wire layer 420. The central core wire body 430 is disposed through the second inner cavity 4211 and connected to each second core wire body 421, so that the second core wire layer 420 is circumferentially covered around the central core wire body 430.

[0033] The above-mentioned low-loss transmission cable assembly 10. Since the transmission core wire member 400 includes a first core wire layer 410, a second core wire layer 420 and a central core wire body 430, the first core wire layer 410 includes a plurality of first core wire bodies 411. The plurality of first core wire bodies 411 are circumferentially arranged around the inner peripheral wall of the wire outer sheath 100, so that the wire outer sheath 100 surrounds and covers the first core wire layer 410.

Thus, the problem that the current is unevenly distributed in the single cable core wire in the prior art is solved. Furthermore, the problem that the current is mainly concentrated on the surface of the single cable core wire in the prior art, so that the internal current density of the single cable core wire is relatively small is avoided, so that the internal current density of the transmission core wire member 400 is relatively large, the resistance of the conductor of the transmission core wire member 400 is reduced, so that the loss power of the transmission core wire member 400 is reduced, and further the power loss of the low-loss transmission cable assembly 10 during current transmission is relatively low.

[0034] As Figure 1 and Figure 3 shown, in one embodiment, the low-loss transmission cable assembly 10 further includes a connector 500. One end of each first core wire body 411, one end of each second core wire body 421 and one end of the central core wire body 430 are all electrically connected to the connector 500.

[0036] As Figure 1 and Figure 3 shown, in one embodiment, the connector 500 is provided with a plurality of connection terminals 510, and the plurality of connection terminals 510 are spaced apart.

[0037] As Figure 1 , Figures 3 to 4 shown, in one embodiment, one end of each first core wire body 411, one end of each second core wire body 421, and one end of the central core wire body 430 are all provided with first identification sleeves 4113; the other end of each first core wire body 411, the other end of each second core wire body 421, and the other end of the central core wire body 430 are all provided with second identification sleeves 4114.

[0038] In one embodiment, the wire outer sheath 100 is an integrally formed structure.

[0039] As Figure 1 and Figure 3 shown, in one embodiment, the first sheath assembly 200 includes a connected first sheath main body 210 and a first extension 220. The first sheath main body 210 covers one end of the wire outer sheath 100, and the first extension 220 is wound around and covers the first core wire layer 410.

[0040] In one embodiment, the first sheath main body 210 and the first extension 220 are an integrally formed structure.

The second sheath main body 310 covers the other end of the wire outer sheath 100, and the second extension 320 is wound around and covers the first core wire layer 410.

[0042] In one embodiment, the second sheath main body 310 and the second extension 320 are an integrally formed structure.

[0043] Compared with the prior art, the present disclosure has at least the following advantages:

[0044] Since the transmission core wire member 400 includes a first core wire layer 410, a second core wire layer 420 and a central core wire body 430, the first core wire layer 410 includes a plurality of first core wire bodies 411. The plurality of first core wire bodies 411 are circumferentially arranged around the inner peripheral wall of the wire outer sheath 100, so that the wire outer sheath 100 surrounds and covers the first core wire layer 410. The second core wire layer 420 includes a plurality of second core wire bodies 421. The plurality of second core wire bodies 421 are circumferentially arranged around the inner peripheral wall of the first core wire layer 410, so that the first core wire layer 410 surrounds and covers the second core wire layer 420. The central core wire body 430 is disposed through the second inner cavity 4211 and connected to each second core wire body 421, so that the second core wire layer 420 surrounds and covers the central core wire body 430, such that the wire outer sheath 100, the first core wire layer 410, the second core wire layer 420 and the central core wire body 430 are arranged in a surrounding and covering and stacked manner. Thus, the low-loss type transmission cable assembly 10 is formed by stacking a plurality of core wire bodies in a surrounding and covering manner. The low-loss type transmission cable assembly 10 is used for transmitting high-frequency alternating current (i.e., current), that is, the transmission core wire member 400 is used for transmitting current. The transmission core wire member 400 is formed by stacking a plurality of core wire bodies in a surrounding and covering manner, so that the conductor surface area of the transmission core wire member 400 is relatively large, and the current is distributed more uniformly in the transmission core wire member 400. Thus, the problem that the current is unevenly distributed in the single cable core wire in the prior art is solved. Furthermore, the problem that the current mainly concentrates on the surface of the single cable core wire in the prior art, so that the internal current density of the single cable core wire is relatively small is avoided. The internal current density of the transmission core wire member 400 is relatively large, so that the resistance of the conductor of the transmission core wire member 400 is reduced, and thus the loss power of the transmission core wire member 400 is reduced. Furthermore, the power loss of the low-loss type transmission cable assembly 10 during current transmission is relatively low.

[0045] The above embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
