The first connector and the second connector are arranged facing each other. One end of the multiple cables is fixedly connected to the first connector, and the other end of the multiple cables is fixedly connected to the second connector. The first connector is provided with a number of first locking through holes, and the second connector is provided with a number of second locking through holes.

[0018] Reference Figure 1 A cable structure for connecting a current transformer and a busbar includes a first connector 1, a second connector 2, and multiple cables 3. The first connector 1 and the second connector 2 are positioned opposite each other. One end of each cable 3 is fixedly connected to the first connector 1, and the other end of each cable 3 is fixedly connected to the second connector 2. The first connector 1 has several first locking through holes 11, and the second connector 2 has several second locking through holes 21. The first connector 1 is in the shape of a "┏", and the second connector 2 is in the shape of a "┓". In this embodiment, there are six cables 3. Of course, the number of cables 3 can be reasonably set according to needs, such as four, five, seven, eight, or other reasonable numbers. In this embodiment, there are two of each of the first locking through hole 11 and the second locking through hole 21. The two first locking through holes 11 are located on the horizontal part of the first connector 1, and the two second locking through holes 21 are located on the horizontal part of the second connector 2. The first connector 1 and the second connector 2 are locked to the voltage transformer and the busbar by bolts passing through the first locking through hole 11 and the second locking through hole 21 respectively.
[0019] Reference Figure 1 and Figure 2 One end of each of the multiple cables 3 is fixedly connected to the outer side of the vertical portion of the first connector 1, and the other end of each of the multiple cables 2 is fixedly connected to the bottom of the vertical portion of the second connector 2. Specifically, this utility model also includes a first fixed terminal 4 and a second fixed terminal 5. One end of each of the multiple cables 3 is fixedly connected to the first fixed terminal 4. A cutout 12 is provided on the side of the vertical portion of the first connector 1, and the first fixed terminal 4 is fixedly connected within the cutout 12. The other end of each of the multiple cables 3 is fixedly connected to the second fixed terminal 5, and the second fixed terminal 5 is fixedly connected to the bottom of the vertical portion of the second connector 2. Specifically, one end of each of the multiple cables 3 is fixedly connected to the bottom of the first fixed terminal 4 by welding, and the first fixed terminal 4 is fixedly connected to the outer side of the vertical portion of the first connector 1 by bolts. The other end of each of the multiple cables 3 is fixedly connected to the bottom of the second fixed terminal 5 by welding, and the second fixed terminal 5 is fixedly connected to the bottom of the vertical portion of the second connector 2 by bolts.
[0020] Reference Figure 1 and Figure 2 Each cable 3 is semi-enclosed in a frame shape, and each cable 3, from the first connector 1 to the second connector 2, sequentially forms a first vertical segment 31, a first horizontal segment 32, a second vertical segment 33, and a second horizontal segment 34. Specifically, as shown... Figure 1 , 2 As shown, the first vertical segment 31 and the second vertical segment 33 are arranged horizontally. The top of the first vertical segment 31 is welded to the bottom of the first fixed terminal 4. The first horizontal segment 32 is located between the bottom of the first vertical segment 31 and the bottom of the second vertical segment 33. The second horizontal segment 34 is located above the first horizontal segment 32 and extends horizontally from the top of the second vertical segment 33 toward the second connector 2. The left end of the second horizontal segment 34 is welded to the right side of the second fixed terminal 5. The layout design of the first vertical segment 31, the first horizontal segment 32, the second vertical segment 33, and the second horizontal segment 34 allows the cable 3 to meet the installation requirements in the switch cabinet while also forming a large semi-enclosed frame space, which can be used for other wiring.
