[0036] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0037] Please see Figure 1-12This invention provides a high-current flexible copper busbar cable T-type connector, including a main cable 1 and a branch cable 2. The main cable 1 has a bare contact area, and one end of the branch cable 2 is electrically connected to the bare contact area. The bare contact area is covered by an insulating box, which includes: an upper cover 3 and a bottom shell 4, which respectively cover the upper and lower sides of the bare contact area and are hinged to each other on one side, while the other opposite side allows the branch cable 2 to extend out; a corner piece 5, which is movably connected to the upper cover 3 and is located at the angle between the main cable 1 and the branch cable 2. One end of the corner piece 5, together with the upper cover 3 and the bottom shell 4, forms a main enclosing hole for the main cable 1 to pass through, while the other end forms a secondary enclosing hole for the branch cable 2 to pass through; and a snap-fit ​​assembly, which is used to snap the corner piece 5 to the bottom shell 4.

[0038] Specifically, both the main cable 1 and the branch cable 2 are flexible copper busbar cables, comprising a conductor, a wrapping layer, and a sheath layer from the inside out. Both the wrapping layer and the sheath layer are made of insulating material. The bare connection area is located in the middle section of the main cable 1. A portion of the wrapping layer and sheath layer is removed from the middle section of the main cable 1, exposing a rectangular section of conductor, which is the bare connection area. The length of the bare connection area matches the width of the exposed conductor at the end of the branch cable 2. The conductor extending from the end of the branch cable 2, in a non-energized environment, forms a T-shape with the bare connection area and is then fixed by bolted electrical contacts. The insulation box is entirely made of insulating material. Existing insulation boxes can be divided into an upper shell and a lower shell, as shown in the reference. Figure 1-2The upper shell has a slot for the branch cable 2 to extend out, and the lower shell has a slot for the main cable 1 to extend out in both directions. A rubber strip is attached to the inner side of the upper surface of the lower shell, and a groove corresponding to the rubber strip is provided on the upper shell. The upper and lower shells are closed and fixedly connected by long screws, thereby using the slots to snap the main cable 1 and the branch cable 2 together. The rubber strip and the groove are fitted to seal the connection gap between the upper and lower shells. However, this type of insulation box is large in size, the slot size is fixed, and the flexibility is poor. The upper cover 3 and the bottom shell 4 are clamped outside the bare area with their hinge axis parallel to the extension direction of the main cable 1. At this time, the length of the upper cover 3 and the bottom shell 4 in the extension direction of the main cable 1 is greater than the length of the bare area, and the length in the extension direction of the branch cable 2 is greater than the length of the conductor extending from the end of the branch cable 2. That is, the upper cover 3 and the bottom shell 4 cover the upper and lower sides of the bare area respectively, and the upper cover 3 and the bottom shell 4 are tightly attached to the outer insulation wall of the main cable 1 and the branch cable 2. The upper cover 3 is L-shaped, and the bottom shell 4 is flat. The upper cover 3 is attached to the opposite side of the branch cable 2 on the main cable 1 with the part of the hinged bottom shell 4. Both the upper cover 3 and the bottom shell 4 are provided with protrusions to surround the main cable 1 and the branch cable 2. The branch cable 2 is connected by a bolt structure; a slider 6 is provided at the upper end of the corner piece 5, and a groove 7 matching the slider 6 is provided on the upper cover 3. The groove 7 limits the movement direction of the slider 6 and is arranged parallel to the extension direction of the branch cable 2. The slider 6 is kept in the groove 7 so that the corner piece 5 can fit against the upper cover 3; the shape of the corner piece 5 near the main cable 1 can fit tightly against the outer wall of the insulation of the main cable 1; preferably, there are two corner pieces 5, which are symmetrically arranged on the lower side of the free end of the upper cover 3. The two corner pieces 5 cooperate with the upper cover 3 and the bottom shell 4 to form a secondary enclosure hole for the branch cable 2 to pass through; the snap-fit ​​assembly snaps the corner piece 5 and the bottom shell 4 together, that is, it maintains the clamping state of the upper cover 3 and the bottom shell 4 on the bare contact area. In practical use, after the main cable 1 and branch cable 2 are electrically contacted and fixedly connected, the upper cover 3 and the bottom shell 4 are folded and clamped from the opposite side of the branch cable 2 to cover the exposed area. This ensures that the upper cover 3 and the bottom shell 4 are tightly fitted to the insulation outer wall of the main cable 1 and the branch cable 2, and that the corner piece 5 is located at the angle between the main cable 1 and the branch cable 2. Then, the corner piece 5 is moved to fit tightly against the insulation outer wall of the main cable 1, thereby forming a main surrounding hole with the upper cover 3 and the bottom shell 4, tightly surrounding the insulation outer wall of the main cable 1. In addition, the two corner pieces 5, together with the upper cover 3 and the bottom shell 4, form a secondary surrounding hole, tightly surrounding the insulation outer wall of the branch cable 2. Finally, the corner piece 5 and the bottom shell 4 are clamped and fixed by the snap-fit ​​assembly, thus locking the clamping state of the upper cover 3 and the bottom shell 4 over the exposed area. This forms an insulating box structure that tightly covers the exposed area, and the insulating box is tightly fitted to the outer wall of the insulation part of the main cable 1 and the branch cable 2, greatly improving the sealing performance, making it waterproof, dustproof, safe and reliable.

[0039] Compared with the prior art, the T-type connector for high-current flexible copper busbar cables proposed in this embodiment of the invention, by setting corner pieces 5, can automatically move and adapt at the angle between the main cable 1 and the branch cable 2 after the upper cover 3 and the bottom shell 4 are tightly covered to cover the exposed area. Adjusting to form a main enclosing hole matching the main cable 1 and a secondary enclosing hole matching the branch cable 2, and then using a snap-fit ​​assembly to snap and fix the corner pieces 5 to the bottom shell 4, thereby forming an insulating box structure that tightly covers the exposed area. The insulating box is in close contact with the outer wall of the insulating part of the main cable 1 and the branch cable 2, greatly improving the sealing performance, making it waterproof, dustproof, safe and reliable.

[0040] As a preferred technical solution in this embodiment, the snap-fit ​​assembly includes a mating groove 8 provided on the side wall of the bottom shell 4, a protruding rib 9 provided on the mating groove 8, a snap block 10 matching the mating groove 8 provided at the lower end of the corner piece 5, and a snap groove 11 matching the protruding rib 9 provided on the inner side of the snap block 10. Specifically, the bottom surface of the protruding rib 9 is inclined, and the end near the hinge axis of the bottom shell 4 is lower in height. The protruding rib 9 and the snap groove 11 are provided in damped contact. The mating groove 8 extends a certain length from the end away from the hinge axis to the other end on the side wall of the bottom shell 4. The protruding rib 9 is provided on the upper side of the mating groove 8, and the end near the hinge axis of the bottom shell 4 is connected to the inner wall of the mating groove 8, while the other end is spaced apart from the end of the mating groove 8 in the same direction. The locking block 10 is matched with the spacing. When the corner piece 5 is in a position away from the hinge axis of the upper cover 3, the corner piece 5 can naturally align the locking block 10 with the spacing left between the upper mating groove 8 and the protruding rib 9 during the folding process of the upper cover 3. When the locking block 10 is embedded in the mating groove 8, the protruding rib 9 corresponds to the locking groove 11 in its extension direction. Thus, by moving the corner piece 5 closer to the hinge axis of the upper cover 3, the corner piece 5 drives the locking block 10 to move in the mating groove 8, and the protruding rib 9 and the locking groove 11 also engage. With the inclined bottom surface of the protruding rib 9 and the damping contact between the protruding rib 9 and the locking groove 11, the upper cover 3 and the bottom shell 4 are brought closer and tightened, and the corner piece 5 and the bottom shell 4 are locked together.

[0041] As a preferred technical solution in this embodiment, the corner piece 5 is provided with a receiving groove 12 on the side near the branch cable 2. A clamping block 13 is elastically and movably disposed in the receiving groove 12. One end of the clamping block 13 can extend out of the receiving groove 12 and match the insulating outer wall of the branch cable 2. Specifically, the corner piece 5 and the clamping block 13 form an L-shape. The elastically movable clamping block 13 is used to automatically match the width of the branch cable 2. The bottom surface of the upper cover 3 is provided with a stop block 14 for limiting the ejection of the clamping block 13. When the corner piece 5 is away from the hinge of the upper cover 3... When the shaft is in position, the clamping block 13 retracts into the storage groove 12, and the stop block 14 just blocks and limits the protruding end of the clamping block 13. This makes it convenient for the corner piece 5 to be installed at the angle between the main cable 1 and the branch cable 2. When the corner piece 5 moves closer to the main cable 1, the corner piece 5 drives the clamping block 13 away from the stop block 14. Then, the clamping block 13 automatically pops out and fits against the insulating outer wall of the branch cable 2. The two sets of corner pieces 5 and clamping blocks 13 automatically cooperate with the upper cover 3 and the bottom shell 4 to form a secondary surrounding hole around the branch cable 2.

[0042] In another embodiment of the present invention, the upper cover 3 is provided with a pull rope assembly for tightening the corner piece 5 close to the outer wall of the insulation of the main cable 1. Specifically, the main function of the snap-fit ​​assembly is to snap the corner piece 5 to the bottom shell 4 to limit the size of the opening between the upper cover 3 and the bottom shell 4. However, the movement of the corner piece 5 cannot be fully limited. Therefore, by providing the pull rope assembly, the corner piece 5 can be tightened close to the outer wall of the insulation of the main cable 1, thereby limiting the movement of the corner piece 5 and ensuring the stable sealing of the insulation box.

[0043] As a preferred embodiment, the rope assembly includes a rope catcher on one side of the hinge shaft of the upper cover 3. A rope end 15 extends from the rope catcher, and a hook 16 is provided on the corner piece 5. After the rope end 15 wraps around the insulating outer wall of the portion where the main cable 1 passes through the main enclosure hole and hooks the hook 16, it is fixedly connected to a retainer 17 on the top surface of the upper cover 3. The rope catcher tightens the rope end 15 to clamp the main cable 1 on the corner piece 5. Specifically, the rope catcher includes a hole seat 18 fixedly provided on the upper cover 3. A button 19 is elastically movably provided within the hole seat 18. A through hole 20 is provided on the hole seat 18, and a misalignment hole 21 is provided on the button 19. Rope head 15 is set through the through hole 20 and the misalignment hole 21; two rope heads 15 are symmetrically distributed on the rope fastener, and the two rope heads 15 are connected together to form a U-shaped head; by pressing the button 19, the through hole 20 and the misalignment hole 21 can be aligned, thereby loosening the rope head 15, and then stretching the U-shaped head can tighten the rope head 15; after the button 19 is released, it automatically pops outward so that the misalignment hole 21 and the through hole 20 are misaligned, thereby clamping the rope head 15; the hook body 16 is set on the outer wall of the corner piece 5 and is set near one end of the main cable 1; the rope head 15 is released from the rope fastener, first along the height of the upper surface of the main cable 1 and around the main cable 1. The rope end 15 is wound around the main cable 1 from the side closest to the branch cable 2, then wrapped back around the underside of the main cable 1, and then wound upwards from the side of the main cable 1 away from the branch cable 2. After completing one loop, the rope end 15 is then placed on the top surface of the cover 3 and connected to the retainer 17. The retainer 17 is made of plastic material and is kept open before connecting the rope end 15. After the rope end 15 is placed inside the retainer 17, the retainer 17 is clamped with pliers or other tools, thereby fixing the rope end 15 to the retainer 17. A protrusion is provided on the outer wall of the cover 3 on the side opposite to the branch cable 2. The protrusion is used to limit the rope end 15 and prevent the rope end 15 from straightening after tightening. The rope end 15 is made of flexible, non-elastic material and is waterproof. In actual use, the rope end 15 wraps around the outer wall of the insulation layer where the main cable 1 passes through the main enclosure hole and hooks the hook body 16. It is then fixedly connected to the fixing device 17 set on the top surface of the cover 3. Then, by stretching the U-shaped head on the rope tie, the rope end 15 is tightened, and the hook body 16 ensures that the corner piece 5 clamps the main cable 1, thereby fixing the corner piece 5 and making the installation state of the insulation box more stable. Furthermore, after the rope end 15 is tightened, it is close to the outside of the gap between the main cable 1 and the main enclosure hole, thereby enhancing the waterproof and dustproof performance of this position.

[0044] A method for manufacturing a high-current flexible copper busbar cable T-type joint, based on the aforementioned high-current flexible copper busbar cable T-type joint, includes: a branch cable 2 is fixedly connected at one end to the bare contact area of ​​the main cable 1 by bolts; the upper cover 3 and the bottom shell 4 are folded and wrapped around the bare contact area from the opposite side of the branch cable 2, ensuring that the upper cover 3 and the bottom shell 4 are tightly fitted to the insulating outer walls of the main cable 1 and the branch cable 2; and the corner piece 5 is located at the angle between the main cable 1 and the branch cable 2, the corner piece 5 is moved to fit tightly against the insulating outer wall of the main cable 1, and then the corner piece 5 is snapped and fixed to the bottom shell 4 by a snap-fit ​​assembly.
