[0042] like Figure 1 As shown, a cable system provided by an embodiment of the present invention includes a first coaxial cable 100, a second coaxial cable 200, a single-core cable 500, and a coaxial cable outer conductor branch connection device. The coaxial cable outer conductor branch connection device includes a first connection component 300 and a second connection component 400.

[0043] The first coaxial cable 100 includes a first inner conductor 110 and a first outer conductor 120 . The connection end of the first coaxial cable 100 is configured such that the first inner conductor 110 extends from the first outer conductor 120 .

[0044] It is understandable that the first outer conductor 120 of the connecting end of the first coaxial cable 100 can be stripped by cutting so that the first inner conductor 110 extends out of the first outer conductor 120. The first outer conductor 120 and the first inner conductor 110 are both made of conductive materials.

[0045] like Figure 4 As shown, it should be noted that the structure of the first coaxial cable 100 includes but is not limited to the above-mentioned first inner conductor 110 and first outer conductor 120. Specifically, the first coaxial cable 100 further includes a first inner insulating layer 130, a first inner shielding layer 140, a first outer insulating layer 150, and a first outer shielding layer 160, wherein the first inner insulating layer 130 is sleeved on the outside of the first inner conductor 110, the first inner shielding layer 140 is sleeved on the outside of the first inner insulating layer 130, the first outer conductor 120 is sleeved on the outside of the first inner shielding layer 140, the first outer insulating layer 150 is sleeved on the outside of the first outer conductor 120, and the first outer shielding layer 160 is sleeved on the outside of the first outer insulating layer 150.

[0046] In which, the connection end of the first coaxial cable 100 is configured as follows: the first inner conductor 110 extends from the first inner insulating layer 130, the first inner insulating layer 130 extends from the first inner shielding layer 140, the first inner shielding layer 140 extends from the first outer conductor 120, the first outer conductor 120 extends from the first outer insulating layer 150, and the first outer insulating layer 150 extends from the first outer shielding layer 160.

[0047] It is understandable that the first outer shielding layer 160, the first outer insulating layer 150, the first outer conductor 120, the first inner shielding layer 140, and the first inner insulating layer 130 of the connecting end of the first coaxial cable 100 can be peeled off in sequence by cutting, so that the first inner conductor 110 extends out of the first inner insulating layer 130, the first inner insulating layer 130 extends out of the first inner shielding layer 140, the first inner shielding layer 140 extends out of the first outer conductor 120, the first outer conductor 120 extends out of the first outer insulating layer 150, and the first outer insulating layer 150 extends out of the first outer shielding layer 160.

[0048] The first inner insulating layer 130 and the first outer insulating layer 150 are made of insulating materials, and the first inner shielding layer 140 and the first outer shielding layer 160 are made of semi-conductive materials.

[0049] It is understandable that the first coaxial cable 100 may further include a first sheath sleeved on the first outer shielding layer 160 .

[0050] like Figure 1 As shown, the second coaxial cable 200 includes a second inner conductor 210 and a second outer conductor 220 . The connection end of the second coaxial cable 200 is configured such that the second inner conductor 210 extends from the second outer conductor 220 .

[0051] It is understandable that the second outer conductor 220 of the connecting end of the second coaxial cable 200 can be stripped by cutting so that the second inner conductor 210 extends out of the second outer conductor 220. The second outer conductor 220 and the second inner conductor 210 are made of conductive material.

[0052] like Figure 5 As shown, it should be noted that the structure of the second coaxial cable 200 includes but is not limited to the second inner conductor 210 and the second outer conductor 220 described above. Specifically, the second coaxial cable 200 further includes a second inner insulating layer 230, a second inner shielding layer 240, a second outer insulating layer 250, and a second outer shielding layer 260; wherein the second inner insulating layer 230 is sleeved on the outside of the second inner conductor 210, the second inner shielding layer 240 is sleeved on the outside of the second inner insulating layer 230, the second outer conductor 220 is sleeved on the outside of the second inner shielding layer 240, the second outer insulating layer 250 is sleeved on the outside of the second outer conductor 220, and the second outer shielding layer 260 is sleeved on the outside of the second outer insulating layer 250.

[0053] In which, the connection end of the second coaxial cable 200 is configured as follows: the second inner conductor 210 extends from the second inner insulating layer 230, the second inner insulating layer 230 extends from the second inner shielding layer 240, the second inner shielding layer 240 extends from the second outer conductor 220, the second outer conductor 220 extends from the second outer insulating layer 250, and the second outer insulating layer 250 extends from the second outer shielding layer 260.

[0054] It is understandable that the second outer shielding layer 260, the second outer insulating layer 250, the second outer conductor 220, the second inner shielding layer 240, and the second inner insulating layer 230 of the connecting end of the second coaxial cable 200 can be peeled off in sequence by cutting, so that the second inner conductor 210 extends out of the second inner insulating layer 230, the second inner insulating layer 230 extends out of the second inner shielding layer 240, the second inner shielding layer 240 extends out of the second outer conductor 220, the second outer conductor 220 extends out of the second outer insulating layer 250, and the second outer insulating layer 250 extends out of the second outer shielding layer 260.

[0055] The second inner insulating layer 230 and the second outer insulating layer 250 are made of insulating materials, and the second inner shielding layer 240 and the second outer shielding layer 260 are made of semi-conductive materials.

[0056] It is understandable that the second coaxial cable 200 may further include a second sheath sleeved on the second outer shielding layer 260 .

[0057] like Figure 1 As shown, it should be noted that the first outer conductor 120 located at the connection end of the first coaxial cable 100 and the second outer conductor 220 located at the connection end of the second coaxial cable 200 are electrically connected through the first connecting assembly 300 .

[0058] It is understandable that the first connecting component 300 is made of conductive material, such as gold, silver, copper, aluminum, etc., and the first connecting component 300 can realize the electrical connection between the first outer conductor 120 of the first coaxial cable 100 and the second outer conductor 220 of the second coaxial cable 200.

[0059] The first connection assembly 300 includes a first conductor 310 electrically connected to the first outer conductor 120 located at the connection end of the first coaxial cable 100, a second conductor 320 electrically connected to the second outer conductor 220 located at the connection end of the second coaxial cable 200, and a conductive bus 330 connecting the first conductor 310 and the second conductor 320; wherein the first conductor 310, the second conductor 320 and the conductive bus 330 can be made of conductive materials such as copper, aluminum or gold.

[0060] The first conductor 310 includes a first sleeve portion 311 and a first connecting portion 312 connected to the first sleeve portion 311. The first sleeve portion 311 is sleeved outside the first outer conductor 120 located at the connection end of the first coaxial cable 100. The second conductor 320 includes a second sleeve portion 321 and a second connecting portion 322 connected to the second sleeve portion 321. The second sleeve portion 321 is sleeved outside the second outer conductor 220 located at the connection end of the second coaxial cable 200. The second connecting portion 322 is connected to the first connecting portion 312 via a conductive bar 330.

[0061] It should be noted that the loose first outer conductor 120 located at the connection end of the first coaxial cable 100 is bundled and then passed through the first sleeve portion 311; the loose second outer conductor 220 located at the connection end of the second coaxial cable 200 is bundled and then passed through the second sleeve portion 321.

[0062] It can be understood that the first outer conductor 120 located at the connection end of the first coaxial cable 100 is inserted into the first sleeve portion 311, which can ensure that the first outer conductor 120 and the first conductor 310 have a larger contact area, thereby enabling the first outer conductor 120 and the first conductor 310 to have better current conduction performance; the second outer conductor 220 located at the connection end of the second coaxial cable 200 is inserted into the second sleeve portion 321, which can ensure that the second outer conductor 220 and the second conductor 320 have a larger contact area, thereby enabling the second outer conductor 220 and the second conductor 320 to have better current conduction performance; and the conductive bar 330 electrically connects the first connection portion 312 and the second connection portion 322, thereby realizing the connection between the first outer conductor 120 and the second outer conductor 220.

[0063] like Figure 1 As shown, it should be noted that the first inner conductor 110 located at the connection end of the first coaxial cable 100 and extending from the first outer conductor 120, and the second inner conductor 210 located at the connection end of the second coaxial cable 200 and extending from the second outer conductor 220, are electrically connected via a second connecting component 400.

[0064] It is understandable that the second connecting component 400 is made of conductive material, such as gold, silver, copper, aluminum, etc., and the second connecting component 400 can realize the electrical connection between the first inner conductor 110 of the first coaxial cable 100 and the second inner conductor 210 of the second coaxial cable 200.

[0065] Combine Figure 1 and Figure 2 Specifically, the second connection component 400 includes a fourth conductor 410 and a fifth conductor 420; wherein the fourth conductor 410 and the fifth conductor 420 can be made of conductive materials such as copper, aluminum or gold.

[0066] The fourth conductor 410 includes a fourth sleeve portion 411 and a fourth connecting portion 412 connected to the fourth sleeve portion 411. The fourth sleeve portion 411 is sleeved on the first inner conductor 110 located at the connection end of the first coaxial cable 100 and extends outside the first outer conductor 120. The fifth conductor 420 includes a fifth sleeve portion 421 and a fifth connecting portion 422 connected to the fifth sleeve portion 421. The fifth sleeve portion 421 is sleeved on the second inner conductor 210 located at the connection end of the second coaxial cable 200 and extends outside the second outer conductor 220. The fifth connecting portion 422 is electrically connected to the fourth connecting portion 412.

[0067] It can be understood that the first inner conductor 110 located at the connection end of the first coaxial cable 100 and extending from the first outer conductor 120 is inserted into the fourth sleeve portion 411, which can ensure that the first inner conductor 110 and the fourth conductor 410 have a larger contact area, thereby enabling better current conduction performance between the first inner conductor 110 and the fourth conductor 410; the second inner conductor 210 located at the connection end of the second coaxial cable 200 and extending from the second outer conductor 220 is inserted into the fifth sleeve portion 421, which can ensure that the second inner conductor 210 and the fifth conductor 420 have a larger contact area, thereby enabling better current conduction performance between the second inner conductor 210 and the fifth conductor 420; and the fourth connecting portion 412 and the fifth connecting portion 422 are electrically connected, which can realize the connection between the first inner conductor 110 and the second inner conductor 210.

[0068] Furthermore, the fourth connection portion 412 and the fifth connection portion 422 overlap each other, and the contact area between the fourth connection portion 412 and the fifth connection portion 422 is large, which can provide better current conduction performance between the fourth conductor 410 and the fifth conductor 420. The fourth connection portion 412 and the fifth connection portion 422 can be fixed by bolts.

[0069] like Figure 1 As shown, further, the coaxial cable outer conductor branch connection device also includes an insulating support member 600, which is supported on the second connection component 400, thereby serving the purpose of supporting the connection end of the first coaxial cable 100 and the connection end of the second coaxial cable 200, and can reduce the risk of the connection end of the first coaxial cable 100 and the connection end of the second coaxial cable 200 bending and sagging under the action of their own gravity.

[0070] It should be noted that the insulating support member 600 is an insulating member, that is, the insulating support member 600 is made of an insulating material, and the insulating support member 600 supports the second connecting assembly 400. This can reduce the safety hazard caused by the current of the second connecting assembly 400 being diverted to other places under the action of the insulating support member 600.

[0071] like Figure 4 、 Figure 5 As shown, the first coaxial cable 100 is further provided with a first clamp 190, which can be fixed in place with screws. The second coaxial cable 200 is further provided with a second clamp 290, which can be fixed in place with screws.

[0072] like Figure 1 、 Figure 3As shown, there are multiple single-core cables 500, such as two, three, or more. Each single-core cable 500 has a conductive core 510 made of a conductive material. The conductive cores 510 of the multiple single-core cables 500 are connected by a conductive bar 330.

[0073] It can be understood that the conductive cores 510 of multiple single-core cables 500 can be connected together using the conductive bar 330, and then the two ends of the conductive bar 330 are electrically connected to the first conductor 310 and the second conductor 320 respectively, so as to electrically connect the multiple single-core cables 500, the first outer conductor 120 of the first coaxial cable 100, and the second outer conductor 220 of the second coaxial cable 200 together.

[0074] Specifically, the single-core cable 500 further includes an insulating layer 520 sheathed over the conductive core 510, and a shielding layer 530 sheathed over the insulating layer 520. The connection end of the single-core cable 500 is configured such that the conductive core 510 extends beyond the insulating layer 520, and the insulating layer 520 extends beyond the shielding layer 530. The conductive core 510 at the connection end of the single-core cable 500, extending beyond the insulating layer 520, is electrically connected to the conductive bar 330.

[0075] It should be noted that the insulating layer 520 is made of insulating material, and the shielding layer 530 is made of semi-conductive material.

[0076] It is understandable that the shielding layer 530 and the insulating layer 520 of the connection end of the single-core cable 500 can be peeled off in sequence by cutting, so that the conductive core 510 extends out of the insulating layer 520 and the insulating layer 520 extends out of the shielding layer 530.

[0077] It is further understandable that the single-core cable 500 may further include a sheath disposed outside the shielding layer 530 .

[0078] like Figure 1 As shown, further, the multiple single-core cables 500 are arranged at intervals, so that the phenomenon of discharge caused by two adjacent single-core cables 500 being close together can be reduced.

[0079] Combine Figure 1 and Figure 3 It should be noted that the first connection assembly 300 also includes a plurality of third conductors 340, and the plurality of third conductors 340 correspond one-to-one to the plurality of single-core cables 500; the third conductor 340 includes a third sleeve portion 341 and a third connection portion 342 connected to the third sleeve portion 341, the third sleeve portion 341 is sleeved on the conductive core 510 located at the connection end of the single-core cable 500 and extending out of the insulating layer 520, and the third connection portion 342 is electrically connected to the conductive bar 330.

[0080] It is understood that the third conductor 340 can be made of a conductive material such as copper, aluminum, or gold. The conductive core 510 at the connection end of the single-core cable 500 is inserted into the third sleeve portion 341, which ensures a larger contact area between the conductive core 510 and the third conductor 340, thereby achieving better current conduction performance between the conductive core 510 and the third conductor 340. The third connecting portion 342 is electrically connected to the conductive bar 330, thereby connecting the conductive core 510 to the first connecting assembly 300.

[0081] In the coaxial cable outer conductor branching and connecting device of the present invention, the first connecting assembly 300 can achieve electrical connection between the first outer conductor 120 of the first coaxial cable 100, the second outer conductor 220 of the second coaxial cable 200, and the conductive cores 510 of multiple single-core cables 500; and the second connecting assembly 400 can achieve electrical connection between the first inner conductor 110 of the first coaxial cable 100 and the second inner conductor 210 of the second coaxial cable 200. The above-mentioned form brings new applications to coaxial cables, making coaxial cables more widely used and thus more diverse cable systems.

[0082] like Figure 1 As shown, it should be noted that the connecting end of the first coaxial cable 100 and the connecting end of the second coaxial cable 200 both extend along a first direction, and the connecting end of the first coaxial cable 100 and the connecting end of the second coaxial cable 200 are arranged opposite each other.
