DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

When the winding arm 5 is lifted relative to the base 4, the base 4 and the supporting plate 6 cooperate to clamp the two layers of conductors 1.

[0033] Specifically, the conductor 1 adopts high-purity copper wire row as the conductor, and has large carrying capacity; the protective layer 2 includes a wrapping layer, an insulation layer and an outer sheath layer from inside to outside, and realizes sufficient coverage of the conductor 1; the insulation layer adopts polyvinyl chloride or cross-linked polyethylene insulation, effectively isolates and reduces eddy current and line loss; the outer sheath layer adopts polyvinyl chloride or polyolefin sheath, is suitable for use in various environments, and the outer sheath layer has no induced current; the conductor 1 adopts high-purity copper wire row conductor, which maximally reduces the influence of eddy current on the carrying capacity, so that the flexible busbar cable can have maximum length under the condition of the same cross-sectional area, thereby improving the carrying capacity; the wrapping layer is used as the cladding layer between the conductor 1 and the insulation layer, which effectively protects the conductor and improves the insulation performance; the insulation layer and the outer sheath layer protect the conductor to some extent, improve the efficiency of the cable, and the sheath is waterproof, moisture-proof and dust-proof, and can be used in various extreme conditions. The mounting hole 3 is preferably a circular hole, and is arranged through the conductor 1 in the thickness direction of the conductor 1; when the two conductors 1 are stacked, the mounting holes 3 thereon are correspondingly arranged; the part of the wiring mechanism in contact with the conductor 1 is not conductive; the base 4 is arranged on the upper side of the conductor 1 in actual use; the winding arm 5 is in U shape and semi-surrounds the outer side of the conductor 1, thereby providing sufficient space for the connection direction of the two conductors 1; the supporting 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 the base 4 and the supporting plate 6 clamp the two stacked conductors 1, and the self-locking can be performed. In actual use, the two busbar rows are parallel and stacked at a set angle with one end conductor 1, and are kept corresponding based on the mounting hole 3, then the winding arm 5 is wrapped outside the stacked conductors 1, the base 4 is connected to the upper conductor 1, the supporting plate 6 is located on the lower side of the lower conductor 1, then the locking assembly controls the winding arm 5 to rise, the winding arm 5 drives the supporting plate 6 to move close to the base 4, thereby clamping the two conductors 1, conversely, the locking assembly controls the winding arm 5 to descend, and the two conductors 1 can be loosened, thus, the wiring or disassembly of the busbar row is facilitated, and the large-area contact of the two conductors 1 can improve the carrying capacity and safety.

[0034] Compared with the prior art, the flexible copper wire row busbar cable for large current provided by the embodiment of the application realizes clamping and fixing of the two stacked conductors 1 through the wiring mechanism, wherein the base 4 connects the mounting holes 3 of the upper conductors 1 to ensure positioning, the winding arm 5 wraps around the side of the conductor 1 to provide sufficient installation space, the supporting 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 smoothly realized, the wiring or disassembly of the busbar row is facilitated, and the large-area contact of the two conductors 1 can improve the carrying capacity and safety.

[0036] As the preferred technical scheme of the embodiment, the base 4 is provided with a positioning convex 10, and the conductive body 1 is provided with a positioning groove 11 matched with the positioning convex 10, specifically, the positioning convex 10 and the positioning groove 11 are arranged, when the base 4 is connected with the mounting hole 3, the positioning convex 10 is embedded into the positioning groove 11 to limit the rotation of the base 4 relative to the conductive body 1.

[0037] The connection between the bus bars is not fixed, and the installation direction of the bus bars needs to be adjusted when necessary. However, in the prior art, the connection and disconnection between the bus bars are not only troublesome, but also easy to cause friction between the bus bars during adjustment, thereby causing power risks such as sparking. The following embodiments are proposed to solve the problem.

[0038] In another embodiment of the application, the base 4 is provided with a circular bin 12, and the circular bin 12 is provided with a tensioning assembly. When the base 4 and the support plate 6 clamp the two layers of conductive bodies 1, the circular bin 12 is embedded into the mounting hole 3 of the lower conductive body 1 and triggers the tensioning assembly to clamp the concave ring 9 in the mounting hole 3. Specifically, the circular bin 12 is used for being embedded into the mounting hole 3, and the tensioning assembly is used for limiting the circular bin 12 in the mounting hole 3 by means of the concave ring 9.

[0039] As the preferred technical solution of the embodiment, the tensioning assembly comprises a throat hole 13 arranged on the side wall of the round bin 12, a resilient ball 14 movably arranged in the throat hole 13, and an extrusion block 15 movably arranged in the round bin 12, wherein the lower end of the extrusion block 15 is wedge-shapedly matched with the resilient ball 14, and the upper end of the extrusion block 15 is provided with a stop post 16 movably penetrating the round bin 12. Specifically, the throat hole 13 penetrates the side wall of the round bin 12, the inner diameter of the end of the throat hole 13 towards the inside of the round bin 12 is uniform and matches the outer diameter of the resilient ball 14, and the inner diameter of the end of the throat hole 13 towards the outside of the round bin 12 is smaller than the outer diameter of the resilient ball 14; the resilient ball 14 only protrudes out of the round bin 12 by a part through the throat hole 13, and the part does not exceed half of the entity of the resilient ball 14; the resilient ball 14 is provided with a plurality of groups of the throat hole 13 and the resilient ball 14 arranged on the circumference of the side wall of the round bin 12; the outermost end of the resilient ball 14 protruding out of the round bin 12 is provided with a radius larger than the radius in the mounting hole 3; the resilient ball 14 can be compressed under force and remains spherical when not under force; when the supporting plate 6 abuts against the bottom surface of the lower conductor 1, the position of the round bin 12 embedded in the mounting hole 3 is just such that the resilient ball 14 corresponds to the concave ring 9 in the mounting hole 3 on the lower conductor 1; the lower end of the extrusion block 15 is in the shape of a circular truncated cone, and the upper end is in the shape of a circular column; when the supporting plate 6 is about to abut against the lower conductor 1, the stop post 16 abuts against the plug-in block 7, so as to be forced to move towards the round bin 12, thereby driving the extrusion block 15 to relatively descend in the round bin 12 to extrude the resilient ball 14, so that when the supporting plate 6 abuts against the conductor 1 subsequently, the resilient ball 14 corresponds to and is embedded in the concave ring 9 to expand and recover, and the extrusion block 15 keeps the resilient ball 14 limited by the largest part of the outer diameter of the extrusion block 15. In addition, when the resilient ball 14 is embedded in the concave ring 9 on the lower conductor 1, the rolling of the resilient ball 14 can also meet the rotation of the conductor 1 around the round bin 12.

[0040] As the preferred technical solution of the embodiment, the lower end of the plug-in block 7 is provided with a plug hole 17 matched with the stop post 16, and specifically, the upper end of the stop post 16 can rotate coaxially in the plug hole 17. In actual use, when the connection direction of the two bus bar rows needs to be adjusted, since the supporting plate 6 is relatively fixed with the lower bus bar row through the tensioning assembly in the above locking process, when the locking assembly drives the winding arm 5 to descend, the winding arm 5 not only drives the supporting plate 6 to descend, but also drives the lower conductor 1 to separate from the upper conductor 1, and then the upper and lower conductors 1 can relatively rotate to adjust the installation direction, and in this process, the two conductors 1 are not in contact to avoid friction and generate sparks and other power risks.

[0041] In still another embodiment of the present application, the locking assembly comprises a stand 18 arranged on the base 4, the outer wall of the stand 18 is threadedly sleeved with a rotating member 19, the upper end of the rotating member 19 is synchronously arranged with a handle 20, the floating seat 21 is fixedly connected around the upper end of the arm 5, the floating seat 21 is axially movably connected with the stand 18 and rotatably connected with the rotating member 19. Specifically, the stand 18 is in a cylindrical shape, the outer wall is provided with threads and is axially provided with a key groove, the floating seat 21 is annularly sleeved outside the stand 18 and is provided with a corresponding key block on the inner wall, the floating seat 21 only moves axially relative to the stand 18 and does not relatively rotate; the rotating member 19 is rotatably connected with the floating seat 21, so that the two can relatively rotate and synchronously move axially. The handle 20 drives the rotating member 19 to rotate, the rotating member 19 and the stand 18 are threadedly fed to move axially, and the floating seat 21 synchronously moves with the rotating member 19 to drive the arm 5 to lift and lower.

Specifically, the first rotating block 22 and the first rotating groove 23 are arranged, so that the stand 18 can rotate axially relative to the base 4; when the limiting assembly limits the rotation of the stand 18 relative to the base 4, rotating the handle 20 drives the rotating member 19 to rotate relative to the stand 18, thereby smoothly controlling the lifting and lowering of the arm 5; when the limiting assembly cancels the rotation of the stand 18 relative to the base 4, the stand 18 can drive the arm 5 to rotate to adjust the position of the arm 5 relative to the conductive body 1, thereby facilitating the installation and connection of another conductive body 1 in a preset direction, such as the "I" shape or the "L" shape connection mode of two conductive bodies 1.

In actual use, when the handle 20 is not lifted, the clamping blocks 31 and the clamping grooves 32 are separated, the polygonal block 25 is embedded in the second limiting groove 27, the handle 20 is rotated, the handle 20 drives the rotating member 19 to rotate, the rotating member 19 rotates relative to the stand column 18 to produce screw feeding effect, so as to control the lifting and lowering of the 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 drives the slide column 24 to move upward through the connecting column 28, the polygonal block 25 is separated from the second limiting groove 27, at this time, the handle 20 drives the slide column 24 to rotate through the connecting column 28, the slide column 24 drives the stand column 18 to rotate, and the stand column 18 drives the arm 5 to rotate through the floating seat 21 to adjust the position.
