[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figure 1-7 , a flexible copper wire bus cable for high current provided by an embodiment of the present invention includes a conductive body 1 and a protective layer 2. The end of the conductive body 1 extends out of the protective layer 2. It further includes: a mounting hole 3 opened at the end of the conductive body 1; a wiring mechanism for pressing the ends of the conductive bodies 1 of two bus cables together, which includes a base 4, a winding arm 5, a support plate 6, and a locking assembly. The base 4 is connected to the mounting hole 3 of the upper conductive body 1. The winding arm 5 bypasses two layers of the conductive bodies 1 and places the support plate 6 under the lower conductive body 1. The locking assembly is used to control the lifting of the winding arm 5 relative to the base 4. When the winding arm 5 rises relative to the base 4, the base 4 and the support plate 6 cooperate to clamp two layers of the conductive bodies 1.

[0033] Specifically, the conductor 1 uses a high-purity copper busbar as the conductor, which has a large current-carrying capacity; the protective layer 2 includes a wrapping layer, an insulating layer, and an outer sheath layer from the inside to the outside, achieving full coverage of the conductor 1; the insulating layer uses polyvinyl chloride or cross-linked polyethylene insulation, effectively isolating and reducing eddy currents and line losses; the outer sheath layer uses polyvinyl chloride or polyolefin sheath, suitable for use in various environments, and there is no induced electricity in the outer sheath layer; the conductor 1 uses a high-purity copper busbar conductor, which minimizes the influence of eddy currents on the current-carrying capacity, enabling the flexible bus cable to achieve the maximum length under the same cross-sectional area, thereby improving the current-carrying capacity; a wrapping layer is used as the covering layer between the conductor 1 and the insulating layer, effectively protecting the conductor and improving the insulation performance; the insulating layer and the outer sheath layer play a certain protective role for the conductor, improving the cable usage efficiency, and the sheath is waterproof, moisture-proof, and dust-proof, and can be used under various extreme conditions. The mounting hole 3 is preferably a round hole, which penetrates the conductor 1 in the thickness direction of the conductor 1; when two conductors 1 are stacked, the mounting holes 3 on them are arranged correspondingly; the part of the wiring mechanism in contact with the conductor 1 is non-conductive; in actual use, the base 4 is arranged on the upper side of the upper conductor 1; the winding arm 5 is U-shaped and semi-surrounds the outside of the conductor 1, thereby providing sufficient space and a sufficient range of options for the connection direction of the two conductors 1; the support plate 6 is arranged on the lower side of the lower conductor 1; the locking mechanism drives the winding arm 5 to rise, so that when the base 4 cooperates with the support plate 6 to clamp the two stacked conductors 1, self-locking can be performed. In actual use of this technical solution, the two busbars are parallelly stacked at a set angle with one end of the conductor 1, and are kept corresponding with the mounting hole 3 as the reference. Then, the winding arm 5 surrounds the outside of the stacked conductors 1, the base 4 is attached and connected to the upper conductor 1, the support plate 6 is located on the lower side of the lower conductor 1, and then the locking assembly is used to control the winding arm 5 to rise. The winding arm 5 drives the support plate 6 to approach the base 4, thereby realizing the clamping of the two conductors 1. On the contrary, the locking assembly controls the winding arm 5 to descend, and the loosening of the two conductors 1 can be realized. In this way, the wiring or disassembly of the busbar is facilitated, and the two conductors 1 are in large-area contact, which can improve the current-carrying capacity and safety.

[0034] Compared with the prior art, a flexible copper busbar cable for high current proposed in the embodiment of the present invention realizes clamping and fixing of two stacked conductors 1 by setting a wiring mechanism. Among them, the base 4 is connected to the mounting hole 3 of the upper conductor 1 to ensure positioning, the winding arm 5 bypasses the side of the conductor 1 to provide sufficient installation space, the support plate 6 cooperates with the base 4 below, and under the lifting control of the locking assembly on the winding arm 5, the clamping or loosening of the two conductors 1 is successfully realized, facilitating the wiring or disassembly of the busbar, and the two conductors 1 are in large-area contact, which can improve the current-carrying capacity and safety.

[0035] As a preferred technical solution of this embodiment, an insertion block 7 is provided on the base 4. An elastic ring 8 protrudes from the outside of the insertion block 7. A concave ring 9 matching the elastic ring 8 is provided in the mounting hole 3. Specifically, the insertion block 7 is used to insert into the mounting hole 3. The outer diameter of the elastic ring 8 in the free state is larger than the inner diameter of the mounting hole 3, while the outer diameter of the elastic ring 8 after being compressed is consistent with the inner diameter of the mounting hole 3. Thus, the base 4 is inserted into the mounting hole 3 by means of the insertion block 7. During the insertion process, the elastic ring 8 is compressed by extrusion. Then, after the elastic ring 8 corresponds to the concave ring 9, the elastic ring 8 expands and restores to snap into the concave ring 9, thereby fixing the base 4 relative to the mounting hole 3.

[0036] As a preferred technical solution of this embodiment, a positioning protrusion 10 is provided on the base 4, and a positioning groove 11 matching the positioning protrusion 10 is provided on the conductor 1. Specifically, due to the arrangement of the positioning protrusion 10 and the positioning groove 11, when the base 4 is connected to the mounting hole 3, the positioning protrusion 10 is embedded in the positioning groove 11 to limit the rotation of the base 4 relative to the conductor 1.

[0037] The connection between busbars is not fixed. When necessary, the installation direction of the busbars needs to be adjusted. In the prior art, the connection and disassembly between busbars are not only troublesome, but also prone to friction between the busbars during adjustment, causing power risks such as arcing. The following embodiments are proposed to solve this problem.

[0038] In another embodiment proposed by the present invention, a circular bin 12 is provided on the support plate 6, and a tensioning assembly is provided on the circular bin 12. When the base 4 and the support plate 6 clamp two layers of conductors 1, the circular bin 12 is embedded in the mounting hole 3 of the lower conductor 1 and triggers the tensioning assembly to engage with the concave ring 9 in the mounting hole 3. Specifically, the circular bin 12 is used to be embedded in the mounting hole 3; the tensioning assembly is used to limit the circular bin 12 in the mounting hole 3 by means of the concave ring 9.

[0039] As a preferred technical solution of this embodiment, the tensioning assembly includes a throat hole 13 provided on the side wall of the silo 12. An elastic ball 14 is movably arranged in the throat hole 13. An extrusion block 15 is movably arranged in the silo 12. The lower end of the extrusion block 15 is arranged in a wedge-shaped fit with the elastic ball 14. The upper end of the extrusion block 15 is provided with a contact column 16 that movably penetrates the silo 12. Specifically, the throat hole 13 penetrates the side wall of the silo 12. The inner diameter of the end facing the inside of the silo 12 is uniform and matches the outer diameter of the elastic ball 14, while the inner diameter of the end facing the outside of the silo 12 is smaller than the outer diameter of the elastic ball 14; the elastic ball 14 only extends out of the silo 12 through the throat hole 13 by a part, not exceeding half of the entity of the elastic ball 14 itself; multiple groups of the throat hole 13 and the elastic ball 14 are arranged in a circle on the side wall of the silo 12; the radius of the outermost end of the elastic ball 14 when it extends out of the silo 12 relative to the axis of the silo 12 is larger than the radius inside the mounting hole 3; the elastic ball 14 can be compressed by force and remains spherical when not under force; when the support plate 6 abuts against the bottom surface of the lower conductor 1, the position where the silo 12 is embedded in the mounting hole 3 just makes the elastic ball 14 correspond to the concave ring 9 in the mounting hole 3 on the lower conductor 1; the lower end of the extrusion block 15 is frustum-shaped, and the upper end is cylindrical; when the support plate 6 is about to fit the lower conductor 1, the contact column 16 will abut against the insertion block 7 and thus be forced to move towards the silo 12, further driving the extrusion block 15 to move downward relative to the inside of the silo 12 to extrude the elastic ball 14. Thus, when the support plate 6 fits the conductor 1 subsequently, the elastic ball 14 corresponds to and is embedded in the concave ring 9 to expand and recover, and the extrusion block 15 keeps the elastic ball 14 limited by the part with the largest outer diameter. In addition, when the elastic ball 14 is embedded in the concave ring 9 on the lower conductor 1, the rolling of the elastic ball 14 can also satisfy the rotation of the conductor 1 around the silo 12.

[0040] As a preferred technical solution of this embodiment, the lower end of the insertion block 7 is provided with a jack 17 that matches the contact column 16. Specifically, the upper end of the contact column 16 can rotate coaxially in the jack 17. In actual use, when the connection direction of the two busbars needs to be adjusted, since during the above tightening process, the support plate 6 is relatively fixed to the lower busbar through the tensioning assembly, when the tightening assembly drives the swing arm 5 to descend, the swing arm 5 not only drives the support plate 6 to descend, but the support plate 6 also drives the lower conductor 1 to separate from the upper conductor 1. Subsequently, the upper and lower conductors 1 can rotate relative to each other to adjust the installation direction, and during this process, the two conductors 1 are spaced apart and do not contact, avoiding power risks such as friction and arcing.

[0041] In another embodiment proposed by the present invention, the locking assembly includes a column 18 provided on a base 4. A rotating member 19 is threadedly sleeved on the outer wall of the column 18. A handle 20 is synchronously rotatably provided at the upper end of the rotating member 19. A floating seat 21 is fixedly connected to the upper end of the arm 5. The floating seat 21 is axially movably connected to the column 18 and rotatably connected to the rotating member 19. Specifically, the column 18 is cylindrical, with a thread provided on the outer wall and a keyway provided along the axis. The floating seat 21 is annularly sleeved outside the column 18, and a corresponding key block is provided on the inner wall. The floating seat 21 only moves axially relative to the column 18 without relative rotation; the rotating connection between the rotating member 19 and the floating seat 21 enables the two to rotate relative to each other and move axially synchronously. The handle 20 drives the rotating member 19 to rotate. The rotating member 19 has a thread feed action with the column 18 and moves axially. The floating seat 21 then moves synchronously with the rotating member 19 to drive the arm 5 to move up and down.

[0042] As a preferred technical solution of this embodiment, a first rotating block 22 is coaxially provided at the lower end of the column 18. A first rotating groove 23 matching the first rotating block 22 is provided on the base 4. A limiting assembly for limiting the rotation of the first rotating block 22 in the first rotating groove 23 is provided on the column 18. Specifically, the arrangement of the first rotating block 22 and the first rotating groove 23 enables the column 18 to rotate axially relative to the base 4; when the limiting assembly restricts the rotation of the column 18 relative to the base 4, rotating the handle 20 drives the rotating member 19 to rotate relative to the column 18, thereby smoothly controlling the lifting of the arm 5. When the limiting assembly cancels the restriction on the rotation of the column 18 relative to the base 4, the column 18 can drive the arm 5 to rotate to adjust the position of the arm 5 relative to the conductor 1, thereby facilitating the installation and connection of another conductor 1 in a preset direction, such as the "one" shape connection of two conductors 1 or the "L" shape connection in two directions.

[0043] As a preferred technical solution of this embodiment, the limiting component includes a sliding column 24 that is elastically axially movable within a column 18. A polygonal block 25 is fixedly provided at the lower end of the sliding column 24. A first limiting groove 26 that matches the polygonal block 25 is provided on the bottom surface of the first rotating block 22. A second limiting groove 27 that matches the polygonal block 25 is provided on the inner bottom surface of the first rotating groove 23. The upper end of the sliding column 24 is connected to the handle 20 through a connecting column 28 that movably penetrates the column 18. Specifically, the sliding column 24 only axially moves relative to the column 18 and does not rotate relatively; a cavity is provided on the inner wall of the upper end of the column 18, and a spring is provided in the cavity. The spring is sleeved outside the connecting column 28, and the upper end of the sliding column 24 abuts against the spring, thereby keeping the sliding column 24 in a downward moving trend relative to the column 18. Further, when the polygonal block 25 corresponds to the second limiting groove 27, the lower half of the polygonal block 25 is embedded in the second limiting groove 27, and the upper half remains in the first limiting groove 26, thereby limiting the rotation of the column 18 relative to the base 4. When the sliding column 24 rises after being stressed and the polygonal block 25 disengages from the second limiting groove 27, the column 18 can rotate relative to the base 4; the setting of the connecting column 28 enables the lifting of the handle 20 to actively drive the sliding column 24 to rise, thereby canceling the restriction on the rotation of the column 18 relative to the base 4; another key groove is axially provided on the outer wall of the connecting column 28, and another key block that matches it is provided on the inner wall of the upper end of the rotating member 19.

[0044] As a preferred technical solution of this embodiment, the upper end of the sliding column 24 is coaxially connected with a second rotating block 29. A second rotating groove 30 that matches the second rotating block 29 is provided at the lower end of the connecting column 28. A plurality of clamping blocks 31 are circumferentially provided at the edge of the inner bottom surface of the second rotating groove 30. A plurality of clamping grooves 32 that match the clamping blocks 31 are circumferentially provided on the second rotating block 29. Specifically, the second rotating block 29 can axially move a certain height within the second rotating groove 30, thereby controlling the engagement and disengagement of the clamping blocks 31 and the clamping grooves 32. And due to the elastic downward moving trend of the sliding column 24 and the self - weight of the connecting column 28, the clamping blocks 31 and the clamping grooves 32 remain separated. During actual use, when the handle 20 is not lifted, the clamping blocks 31 and the clamping grooves 32 are separated, and the polygonal block 25 is embedded in the second limiting groove 27. When the handle 20 is rotated, the handle 20 drives the rotating member 19 to rotate, and the rotating member 19 rotates relative to the column 18 to perform a thread feeding function, thereby controlling the lifting of the swing arm 5 through the floating seat 21; when the handle 20 is lifted, the clamping blocks 31 and the clamping grooves 32 are engaged, and the handle 20 pulls the sliding column 24 to rise through the connecting column 28, and the polygonal block 25 leaves the second limiting groove 27. At this time, when the handle 20 is rotated again, the handle 20 drives the sliding column 24 to rotate through the connecting column 28, the sliding column 24 drives the column 18 to rotate, and the column 18 drives the swing arm 5 to rotate through the floating seat 21 to adjust the position.

[0045] Only certain exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
