[0040] It should be noted that the structure of the coaxial cable 100 includes but is not limited to the above structure. For some coaxial cables 100 , they may further include a sheath disposed outside the outer shielding layer 140 .

[0041] The first cable 200 includes a first conductive core 210, a first insulating layer 230 sleeved outside the first conductive core 210, and a first shielding layer 220 sleeved outside the first insulating layer 230; wherein, the connection end of the first cable 200 is configured as follows: the first conductive core 210 extends out of the first insulating layer 230, and the first insulating layer 230 extends out of the first shielding layer 220; the first conductive core 210 located at the connection end of the first cable 200 and extending out of the first insulating layer 230 is electrically connected to the inner conductor 110 located at the connection end of the coaxial cable 100 and extending out of the inner insulating layer 150.

[0042] It is understood that the first shielding layer 220 and the first insulating layer 230 at the connection end of the first cable 200 can be peeled off by cutting, so that the first conductive core 210 extends out of the first insulating layer 230, and the first insulating layer 230 extends out of the first shielding layer 220. The first conductive core 210 is made of a conductive material, the first shielding layer 220 is made of a semi-conductive material, and the first insulating layer 230 is made of an insulating material.

[0043] The second cable 300 includes a second conductive core 310, a second insulating layer 330 sleeved outside the second conductive core 310, and a second shielding layer 320 sleeved outside the second insulating layer 330, wherein the connection end of the second cable 300 is configured as follows: the second conductive core 310 extends out of the second insulating layer 330, and the second insulating layer 330 extends out of the second shielding layer 320; the second conductive core 310 located at the connection end of the second cable 300 and extending out of the second insulating layer 330 is electrically connected to the outer conductor 130 located at the connection end of the coaxial cable 100 and extending out of the outer insulating layer 160.

[0044] It is understood that the second shielding layer 320 and the second insulating layer 330 at the connection end of the second cable 300 can be peeled off by cutting, so that the second conductive core 310 extends out of the second insulating layer 330, and the second insulating layer 330 extends out of the second shielding layer 320. The second conductive core 310 is made of a conductive material, the second shielding layer 320 is made of a semi-conductive material, and the second insulating layer 330 is made of an insulating material.

[0045] In the cable system of the present invention, the first cable 200 and the second cable 300 can be connected to the inner conductor 110 and the outer conductor 130 of the coaxial cable 100 respectively, and the coaxial cable 100 can be used as a transmission line to transmit power to the first cable 200 and the second cable 300.

[0046] It should be noted that the coaxial cable connection device includes an inner conductor lead-out conductor 111, which is electrically connected to the inner conductor 110 located at the connection end of the coaxial cable 100 and extending out of the inner insulating layer 150; wherein, the first conductive core 210 located at the connection end of the first cable 200 and extending out of the first insulating layer 230 is electrically connected to the inner conductor lead-out conductor 111; in this way, with the help of the inner conductor lead-out conductor 111, the connection between the inner conductor 110 of the coaxial cable 100 and the first conductive core 210 of the first cable 200 can be achieved.

[0047] The inner conductor lead-out conductor 111 may be made of conductive materials such as copper, aluminum or gold.

[0048] Furthermore, the inner conductor lead-out conductor 111 has a first sleeve portion 1111 and a first connecting plate 1112 connected to the first sleeve portion 1111. The first sleeve portion 1111 is sleeved on the inner conductor 110 located at the connection end of the coaxial cable 100 and extending out of the inner insulating layer 150. The first connecting plate 1112 is electrically connected to the first conductive core 210 located at the connection end of the first cable 200 and extending out of the first insulating layer 230.

[0049] It can be understood that the inner conductor 110 located at the connection end of the coaxial cable 100 and extending out of the inner insulating layer 150 is passed through the first sleeve portion 1111, which can ensure that the inner conductor 110 and the inner conductor lead-out conductor 111 have a larger contact area, thereby enabling the inner conductor 110 and the inner conductor lead-out conductor 111 to have better current conduction performance.

[0050] Combine Figure 1 and Figure 2Furthermore, the coaxial cable connection device also includes a connecting conductor 600, which includes a first conductive plate 610 and a second conductive plate 620. The first conductive plate 610 is stacked and fitted with the first connecting plate 1112. The first conductive core 210 located at the connection end of the first cable 200 and extending out of the first insulating layer 230 is electrically connected to the second conductive plate 620.

[0051] It can be understood that the connecting conductor 600 is L-shaped, and the first conductive plate 610 and the first connecting plate 1112 are stacked and fitted together, so that the two can contact each other, thereby achieving conductivity between the two. In addition, the first conductive plate 610 and the first connecting plate 1112 are stacked and fitted together, which can ensure that the inner conductor lead-out conductor 111 and the connecting conductor 600 have a larger contact area, thereby achieving better current conduction performance between the inner conductor lead-out conductor 111 and the connecting conductor 600.

[0052] It should be noted that the first conductive plate 610 and the first connecting plate 1112 can be fixed by means of bolts.

[0053] like Figure 1 、 Figure 2 As shown, the coaxial cable connection device further includes a first conductive core lead-out conductor 211. The first conductive core lead-out conductor 211 is electrically connected to the first conductive core 210 located at the connection end of the first cable 200 and extending out of the first insulating layer 230. The first conductive core lead-out conductor 211 is also electrically connected to the second conductive plate 620. In this way, the electrical connection between the first conductive core 210 and the connecting conductor 600 can be achieved with the help of the first conductive core lead-out conductor 211.

[0054] Furthermore, the first conductive core lead-out conductor 211 has a second sleeve portion 2111 and a second connecting plate 2112 connected to the second sleeve portion 2111. The second sleeve portion 2111 is sleeved on the connection end of the first cable 200 and extends out of the first conductive core 210 of the first insulating layer 230. The second connecting plate 2112 is stacked and fitted with the second conductive plate 620.

[0055] It can be understood that the first conductive core 210 located at the connection end of the first cable 200 and extending out of the first insulating layer 230 is inserted into the second sleeve portion 2111, which can ensure that the first conductive core 210 and the first conductive core lead-out conductor 211 have a larger contact area, thereby enabling the first conductive core 210 and the first conductive core lead-out conductor 211 to have better current conduction performance; in addition, the second connecting plate 2112 and the second conductive plate 620 are stacked and fitted together, which can ensure that the first conductive core lead-out conductor 211 and the connecting conductor 600 have a larger contact area, thereby enabling the first conductive core lead-out conductor 211 and the connecting conductor 600 to have better current conduction performance.

[0056] It should be noted that, in some other embodiments, the connecting conductor 600 may not be provided, and the second connecting plate 2112 and the first connecting plate 1112 may be directly stacked and fitted together. This ensures that the first conductive core lead conductor 211 and the inner conductor lead conductor 111 have a larger contact area, and can provide better current conduction performance between the first conductive core lead conductor 211 and the inner conductor lead conductor 111.

[0057] like Figure 1 As shown, in some embodiments, the coaxial cable connection device further includes an outer conductor lead-out conductor 131. The outer conductor lead-out conductor 131 is electrically connected to the outer conductor 130 located at the connection end of the coaxial cable 100 and extending out of the outer insulating layer 160. The second conductive core 310 located at the connection end of the second cable 300 and extending out of the second insulating layer 330 is electrically connected to the outer conductor lead-out conductor 131. In this way, with the help of the outer conductor lead-out conductor 131, the outer conductor 130 of the coaxial cable 100 and the second conductive core 310 of the second cable 300 can be connected.

[0058] The outer conductor lead conductor 131 can be made of conductive materials such as copper, aluminum or gold.

[0059] It should be noted that the loose outer conductors 130 located at the connection end of the coaxial cable 100 and extending out of the outer insulating layer 160 can be bundled and then connected to the outer conductor lead-out conductor 131 .

[0060] Among them, the outer conductor lead-out conductor 131 has a third sleeve portion 1311 and a third connecting plate 1312 connected to the third sleeve portion 1311. The third sleeve portion 1311 is sleeved on the outer conductor 130 located at the connection end of the coaxial cable 100 and extending out of the outer insulating layer 160. The third connecting plate 1312 is electrically connected to the second conductive core 310 located at the connection end of the second cable 300 and extending out of the second insulating layer 330.

[0061] It can be understood that the outer conductor 130 located at the connection end of the coaxial cable 100 and extending out of the outer insulating layer 160 is passed through the third sleeve portion 1311, which can ensure that the outer conductor lead-out conductor 131 and the outer conductor 130 have a larger contact area, thereby enabling the outer conductor lead-out conductor 131 and the outer conductor 130 to have better current conduction performance.

[0062] It is further understood that the loose outer conductors 130 located at the connection end of the coaxial cable 100 and extending out of the outer insulating layer 160 can be bundled and then passed through the third sleeve portion 1311 .

[0063] Furthermore, the coaxial cable connection device also includes a second conductive core lead-out conductor 311. The second conductive core lead-out conductor 311 is electrically connected to the second conductive core 310 located at the connection end of the second cable 300 and extending from the second insulating layer 330. The second conductive core lead-out conductor 311 is also electrically connected to the outer conductor lead-out conductor 131. Thus, the electrical connection between the second conductive core 310 and the outer conductor lead-out conductor 131 can be achieved with the aid of the second conductive core lead-out conductor 311.

[0064] The second conductive core lead conductor 311 can be made of conductive materials such as copper, aluminum or gold.

[0065] Specifically, the second conductive core lead-out conductor 311 has a fourth sleeve portion 3111 and a fourth connecting plate 3112 connected to the fourth sleeve portion 3111. The fourth sleeve portion 3111 is sleeved on the connection end of the second cable 300 and extends out of the second conductive core 310 of the second insulating layer 330. The fourth connecting plate 3112 is stacked and fitted with the third connecting plate 1312.

[0066] It can be understood that the second conductive core 310 located at the connection end of the second cable 300 and extending out of the second insulating layer 330 is inserted into the fourth sleeve portion 3111, which can ensure that the second conductive core 310 and the second conductive core lead-out conductor 311 have a larger contact area, thereby enabling the second conductive core 310 and the second conductive core lead-out conductor 311 to have better current conduction performance. In addition, the third connecting plate 1312 and the fourth connecting plate 3112 are stacked and fitted together, which can ensure that the second conductive core lead-out conductor 311 and the outer conductor lead-out conductor 131 have a larger contact area, thereby enabling the second conductive core lead-out conductor 311 and the outer conductor lead-out conductor 131 to have better current conduction performance.

[0067] It should be noted that the third connecting plate 1312 and the fourth connecting plate 3112 can be fixed by means of bolts.

[0068] like Figure 1 As shown, in some embodiments, the connecting end of the coaxial cable 100 is arranged horizontally; the coaxial cable connecting device also includes a fixing member 400, a second fixing member 700 and a first insulating support member 500, the first fixing member 400 is sleeved on the outside of the coaxial cable 100 and is staggered with the connecting end of the coaxial cable 100 along the horizontal direction, the second fixing member 700 is used to be sleeved on the outside of the first cable 200, and the first insulating support member 500 supports the inner conductor to lead out the conductor 111.

[0069] It is understood that the first fixing member 400 and the first insulating support member 500 work together to position the connecting end of the coaxial cable 100. The first fixing member 400 can be a clamp that fits over the coaxial cable 100 and can be secured in place with screws. Furthermore, the first insulating support member 500 supports the inner conductor lead-out conductor 111, preventing the connecting end of the coaxial cable 100 from bending or sagging under its own weight and ensuring that the connecting end of the coaxial cable 100 is positioned horizontally. Similarly, the second fixing member 700 and the first insulating support member 500 work together to position the connecting end of the first cable 200.

[0070] It should be noted that the first insulating support 500 is made of insulating material and supports the inner conductor lead conductor 111. This can reduce the safety hazard caused by the current on the inner conductor lead conductor 111 being diverted to other places under the action of the first insulating support 500.

[0071] Furthermore, the coaxial cable connection device further includes a third fixing member 800 and a second insulating support member 900 . The third fixing member 800 is used to be sleeved on the outside of the second cable 300 , and the second insulating support member 900 supports the third connecting plate 1312 and the fourth connecting plate 3112 .

[0072] It is understood that the third fixing member 800 and the second insulating support member 900 work together to position the connection end of the second cable 300. The third fixing member 800 may be a clamp that is sleeved over the second cable 300 and fixed in place with screws.
