[0045] 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 made of conductive materials.

[0046] 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.

[0049] 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.

[0050] It is understandable that the first coaxial cable 100 may further include a first sheath sleeved on the first outer shielding layer 160 .

[0051] Combine Figure 1 and Figure 3 The second coaxial cable 200 includes a second inner conductor 210 and a second outer conductor 220 , and 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 .

[0052] 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.

[0053] It should be noted that the structure of the second coaxial cable 200 includes, but is not limited to, the aforementioned second inner conductor 210 and second outer conductor 220. 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. The second inner insulating layer 230 is sheathed over the second inner conductor 210, the second inner shielding layer 240 is sheathed over the second inner insulating layer 230, the second outer conductor 220 is sheathed over the second inner shielding layer 240, the second outer insulating layer 250 is sheathed over the second outer conductor 220, and the second outer shielding layer 260 is sheathed over the second outer insulating layer 250.

[0055] 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.

[0056] 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.

[0057] It is understandable that the second coaxial cable 200 may further include a second sheath sleeved on the second outer shielding layer 260 .

[0058] 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 through the first connecting component 300.

[0059] 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 inner conductor 110 of the first coaxial cable 100 and the second inner conductor 210 of the second coaxial cable 200.

[0060] 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 via the second connecting assembly 500 .

[0061] It is understandable that the second connecting component 500 is made of conductive material, such as gold, silver, copper, aluminum, etc., and the second connecting component 500 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.

[0062] like Figure 1As shown, there are multiple single-core cables 400, for example, two, three, or more. Each single-core cable 400 has a conductive core 410 made of a conductive material. The conductive cores 410 of the multiple single-core cables 400 are connected via a first conductive bar 600, which is electrically connected to the first connection assembly 300. The first conductive bar 600 is made of a conductive material, such as gold, silver, copper, or aluminum.

[0063] It can be understood that the conductive cores 410 of multiple single-core cables 400 can be connected together by using the first conductive bar 600, and then the first conductive bar 600 is electrically connected to the first connecting assembly 300, so as to electrically connect the multiple single-core cables 400 to the first inner conductor 110 of the first coaxial cable 100 and the second inner conductor 210 of the second coaxial cable 200.

[0064] Furthermore, the multiple single-core cables 400 are arranged at intervals, so that the phenomenon of discharge caused by two adjacent single-core cables 400 being close together can be reduced.

[0065] In the coaxial cable inner conductor branch connection device of the present invention, the first connection assembly 300 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 second connection assembly 500 can achieve 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; the first conductive bar 600 can be used to connect the conductive cores 410 of multiple single-core cables 400 together, and then the first conductive bar 600 is electrically connected to the first connection assembly 300, so as to achieve electrical connection between multiple single-core cables 400 and 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 the application of coaxial cables more extensive, thereby making cable systems more diverse.

[0066] It should be noted that the connection end of the first coaxial cable 100 and the connection end of the second coaxial cable 200 are arranged opposite to each other, and the first connecting assembly 300 is connected between the connection end of the first coaxial cable 100 and the connection end of the second coaxial cable 200 .

[0067] Specifically in this embodiment, the connecting end of the first coaxial cable 100 and the connecting end of the second coaxial cable 200 are both arranged horizontally, and the connecting end of the first coaxial cable 100 and the connecting end of the second coaxial cable 200 are arranged opposite to each other, which is conducive to reducing the distance between the connecting end of the first coaxial cable 100 and the second coaxial cable 200, thereby reducing the material used for the first connecting component 300.

[0068] like Figure 1 As shown, further, the first connection component 300 includes a first connection conductor 310 and a second connection conductor 320; wherein the first connection conductor 310 and the second connection conductor 320 can be made of conductive materials such as copper, aluminum or gold.

[0069] like Figures 1 to 3 As shown, the first connecting 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 on the first inner conductor 110 located at the connection end of the first coaxial cable 100 and extending out of the first outer conductor 120, the second connecting 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 on the second inner conductor 210 located at the connection end of the second coaxial cable 200 and extending out of the second outer conductor 220, and the second connecting portion 322 is electrically connected to the first connecting portion 312.

[0070] 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 first sleeve portion 311, which can ensure that the first inner conductor 110 and the first connecting conductor 310 have a larger contact area, thereby enabling better current conduction performance between the first inner conductor 110 and the first connecting conductor 310; 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 second sleeve portion 321, which can ensure that the second inner conductor 210 and the second connecting conductor 320 have a larger contact area, thereby enabling better current conduction performance between the second inner conductor 210 and the second connecting conductor 320; and the first connecting portion 312 and the second connecting portion 322 are electrically connected, which can realize the connection between the first inner conductor 110 and the second inner conductor 210.

[0071] Furthermore, the first connection portion 312 and the second connection portion 322 overlap each other, and the contact area between the first connection portion 312 and the second connection portion 322 is large, which can provide better current conduction performance between the first connection conductor 310 and the second connection conductor 320. The first connection portion 312 and the second connection portion 322 can be fixed by bolts.

[0072] like Figure 1 As shown, in some embodiments, the second connection component 500 includes a third connection conductor 510, a fourth connection conductor 520 and a second conductive bar 530; wherein the third connection conductor 510, the fourth connection conductor 520 and the second conductive bar 530 can be made of conductive materials such as copper, aluminum or gold.

[0074] 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 third sleeve portion 511; the loose second outer conductor 220 located at the connection end of the second coaxial cable 200 is bundled and then passed through the fourth sleeve portion 521.

[0075] 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 third sleeve portion 511, which can ensure that the first outer conductor 120 and the third connecting conductor 510 have a larger contact area, thereby enabling the first outer conductor 120 and the third connecting conductor 510 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 fourth sleeve portion 521, which can ensure that the second outer conductor 220 and the fourth connecting conductor 520 have a larger contact area, thereby enabling the second outer conductor 220 and the fourth connecting conductor 520 to have better current conduction performance; and the second conductive bar 530 electrically connects the third connecting portion 512 and the fourth connecting portion 522, thereby realizing the connection between the first outer conductor 120 and the second outer conductor 220.

[0076] like Figure 1 As shown, further, the coaxial cable inner conductor branch connection device also includes an insulating support member 800, which is supported on the second connection component 500, 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.

[0077] It should be noted that the insulating support member 800 is an insulating member, that is, the insulating support member 800 is made of an insulating material, and the insulating support member 800 supports the second connecting assembly 500. This can reduce the safety hazard caused by the current of the second connecting assembly 500 being diverted to other places under the action of the insulating support member 800.

[0078] like Figure 2As shown. Furthermore, the first coaxial cable 100 is also provided with a first clamp 190, the first clamp 190 and the connection end of the first coaxial cable 100 are staggered in the horizontal direction, and the first clamp 190 can be fixed in the corresponding position by means of screws. Figure 3 As shown, the second coaxial cable 200 is further provided with a second clamp 290 . The second clamp 290 and the connecting end of the second coaxial cable 200 are staggered in the transverse direction. The second clamp 290 can be fixed at the corresponding position by screws.

[0079] like Figure 1 、 Figure 4 As shown, it should be noted that the coaxial cable inner conductor branch connection device also includes a plurality of fifth connecting conductors 700, and the plurality of fifth connecting conductors 700 correspond one-to-one to the plurality of single-core cables 400; the fifth connecting conductor 700 includes a fifth sleeve portion 710 and a fifth connection portion 720 connected to the fifth sleeve portion 710, the fifth sleeve portion 710 is sleeved on the conductive core 410 located at the connection end of the single-core cable 400, and the fifth connection portion 720 is electrically connected to the first conductive bar 600.

[0080] It is understood that the fifth connecting conductor 700 can be made of a conductive material such as copper, aluminum, or gold. The conductive core 410 at the connection end of the single-core cable 400 is inserted into the fifth sleeve portion 710, ensuring a larger contact area between the conductive core 410 and the fifth connecting conductor 700, thereby achieving better current conduction performance between the conductive core 410 and the fifth connecting conductor 700. The fifth connecting portion 720 is electrically connected to the first conductive bar 600, thereby connecting the conductive core 410 to the first connecting assembly 300.

[0082] It should be noted that both the first cable terminal 170 and the second cable terminal 180 are existing cable terminal structures. The stress cone sleeve of the first cable terminal 170 is located at the break in the first inner shielding layer 140 at the connection end of the first coaxial cable 100. The first cable terminal 170 can optimize the electric field at the break in the first inner shielding layer 140 at the connection end of the first coaxial cable 100, making the electric field distribution at this location more uniform, effectively controlling electrical stress, and improving the reliability of the cable system operation. The stress cone sleeve of the second cable terminal 180 is located at the break in the first outer shielding layer 160 at the connection end of the first coaxial cable 100.

[0083] like Figure 3 As shown, further, the coaxial cable inner conductor branch connection device also includes a third cable terminal 270 that is sleeved on the connection end of the second coaxial cable 200 and sleeved on the break of the second inner shielding layer 240, and a fourth cable terminal 280 that is sleeved on the connection end of the second coaxial cable 200 and sleeved on the break of the second outer shielding layer 260.

[0084] It should be noted that both the third cable terminal 270 and the fourth cable terminal 280 are existing cable terminal structures. The stress cone sleeve of the third cable terminal 270 is located at the break in the second inner shielding layer 240 at the connection end of the second coaxial cable 200. The third cable terminal 270 can optimize the electric field at the break in the second inner shielding layer 240 at the connection end of the second coaxial cable 200, making the electric field distribution at this location more uniform, effectively controlling electrical stress, and improving the reliability of the cable system operation. The stress cone sleeve of the fourth cable terminal 280 is located at the break in the second outer shielding layer 260 at the connection end of the second coaxial cable 200.

[0085] like Figure 4 As shown, the single-core cable 400 further includes an insulating layer 420 sheathed over the conductive core 410, and a shielding layer 430 sheathed over the insulating layer 420. The connection end of the single-core cable 400 is configured such that the conductive core 410 extends from the insulating layer 420, and the insulating layer 420 extends from the shielding layer 430. The insulating layer 420 is made of an insulating material, and the shielding layer 430 is made of a semi-conductive material.

[0086] It is understood that the shielding layer 430 and the insulating layer 420 at the connection end of the single-core cable 400 can be successively stripped by cutting, so that the conductive core 410 extends out of the insulating layer 420, and the insulating layer 420 extends out of the shielding layer 430. The conductive core 410 at the connection end of the single-core cable 400 and extending out of the insulating layer 420 is electrically connected to the first conductive bar 600.

[0087] It is understandable that the single-core cable 400 may further include a sheath disposed outside the shielding layer 430 .

[0088] The coaxial cable inner conductor branch connection device further includes a fifth cable terminal 440 which is sleeved on the connection end of the single-core cable 400 and sleeved on the break of the shielding layer 430 .

[0089] It should be noted that the fifth cable terminal 440 is an existing cable terminal structure. The stress cone of the fifth cable terminal 440 is located at the break in the shielding layer 430 at the connection end of the single-core cable 400. The fifth cable terminal 440 can optimize the electric field at the break in the shielding layer 430 at the connection end of the single-core cable 400, making the electric field distribution at this location more uniform, effectively controlling electrical stress, and improving the reliability of the cable system operation.

[0090] In the cable system of the present invention, the first connecting assembly 300 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 second connecting assembly 500 can achieve 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; the first conductive bar 600 can be used to connect the conductive cores 410 of multiple single-core cables 400 together, and then the first conductive bar 600 is electrically connected to the first connecting assembly 300 to achieve electrical connection between the multiple single-core cables 400 and 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 forms bring new applications to coaxial cables, making the application of coaxial cables more extensive, thereby making cable systems more diverse.
