[0030] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0031] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0032] This embodiment provides Figures 1 to 4 The copper stranded wire connection joint shown is easy to construct and includes: a copper stranded wire connection assembly 1, a convenient hanging and clamping component 4, a first movable component 8, and a second movable component 9.

[0033] In this embodiment, the copper stranded wire connection assembly 1 is used to make a conductive connection between the grounding trunk line and the natural grounding body, and the copper stranded wire connection assembly 1 includes a copper stranded wire portion 2 connected to the grounding trunk line and a galvanized steel 3 connected to the natural grounding body; the copper stranded wire connection assembly 1 serves as the main body of the overall structure and is used to achieve a conductive connection between the grounding trunk line and the natural grounding body. It accomplishes this task through its components, the copper stranded wire portion 2 and the galvanized steel 3. The copper stranded wire portion 2 is directly connected to the grounding trunk line and is part of the conductive path, responsible for conducting current from the grounding point to the copper stranded wire connection assembly 1. The galvanized steel 3 is connected to the natural grounding body. The natural grounding body is preferably a threaded steel bar, which provides a stable and corrosion-resistant contact surface to ensure long-term and effective conductive performance.

[0034] In this embodiment, two convenient hanging and clamping components 4 are symmetrically arranged and are respectively connected to the bottom surface of the copper stranded wire part 2 and the galvanized steel 3. The two convenient hanging and clamping components 4 are arranged opposite to each other and the opposite ends can be hung and clamped on the grounding trunk line and the natural grounding body respectively; the convenient hanging and clamping components 4 enable the entire connecting device to be quickly and easily installed on the grounding trunk line, and can be firmly fixed.

[0035] In this embodiment, the first movable component 8 is movably arranged on the copper stranded wire portion 2 and carries and connects one of the convenient hanging and clamping components 4; the second movable component 9 is movably arranged inside the galvanized steel 3 and carries and connects the other convenient hanging and clamping component 4.

[0036] In this embodiment, the convenient hanging and clamping component 4 includes an L-hook member 5, and the two L-hook members 5 are arranged horizontally relative to each other and can be hung on the grounding main line and the natural grounding body from opposite ends. The two L-hook members 5 have an elastic upward clamping end 15 at the opposite end, and the elastic upward clamping end 15 is used to upwardly clamp the grounding main line or the natural grounding body. The design of the elastic upward clamping end 15 and the hanging clamping part 16 facilitates hanging on the grounding main line or the natural grounding body, while ensuring good electrical contact. The design of the elastic upward clamping end 15 allows the L-hook member 5 to produce a certain elastic deformation when it contacts the grounding main line or the natural grounding body. When the L-hook member 5 is pressed under the target object, the elastic upward clamping end 15 will temporarily bend outward, allowing the L-hook member 5 to slide in smoothly; once it enters the desired position, the elastic upward clamping end 15 will return to its original shape, tightly clamping the target object, providing good mechanical fixation. The hooking clamping portion 16 can directly bear and support the grounding trunk line or the natural grounding body, thereby ensuring the stability and reliability of the connection.

[0037] In this embodiment, the two L-shaped hook members 5 are arranged horizontally relative to each other, which means that they clamp the target object from both sides like a pair of pliers, providing uniform clamping force.

[0038] In this embodiment, the L-shaped hook 5 is connected to the copper strand 2 and the galvanized steel 3 via a first movable member 8 and a second movable member 9, respectively. This structure not only allows the position of the L-shaped hook 5 to be adjusted as needed, but also maintains sufficient freedom during installation, making it easier for the operator to accurately place the L-shaped hook 5 in the desired position.

[0039] In this embodiment, a hooking clamping portion 16 for supporting and hooking a grounding trunk line or a natural grounding body is provided in the included angle between the two L-shaped hook members 5 . The hooking clamping portion 16 is located behind the adjacent elastic upturned clamping end portion 15 .

[0040] In this embodiment, the first movable component 8 includes a sliding sleeve 13 that is sleeved on the side of the copper stranded wire portion 2 and a first locking bolt 14 that is threaded through the upper part of the sliding sleeve 13. The screw end of the first locking bolt 14 passes through the interior of the sliding sleeve 13 and is pressed down to abut against the copper stranded wire portion 2.

[0041] In this embodiment, one end of one of the L-shaped hook members 5, distal from the adjacent elastically upturned clamping end 15, is welded to the lower outer wall of the sliding member 13. This allows the sliding member 13 to move linearly along the copper stranded portion 2, driving the associated L-shaped hook member 5 to move synchronously. The sliding member 13 is part of the first movable component 8 and slides along the copper stranded portion 2, enabling flexible positioning of the L-shaped hook member 5. A first locking bolt 14 secures the sliding member 13 in place, preventing the L-shaped hook member 5 from shifting due to external factors.

[0042] In this embodiment, the second movable component 9 comprises a T-shaped slot 7 formed on the bottom surface of the galvanized steel 3 and a T-shaped slider 17 that slides and engages within the T-shaped slot 7. Another L-shaped hook 5 has one end, distal from the adjacent elastically upturned clamping end 15, welded to the bottom surface of the T-shaped slider 17. When the T-shaped slider 17 moves linearly within the T-shaped slot 7, it drives the connected L-shaped hook 5 to move synchronously. The top surface of the galvanized steel 3 is symmetrically provided with multiple threaded holes 6 extending through the T-shaped slot 7. A second locking bolt 18 is threadedly connected to one of the threaded holes 6, the screw end of which abuts the top surface of the T-shaped slider 17. The T-shaped slot 7, located within the galvanized steel 3, provides a track for the T-shaped slider 17, allowing the position of the L-shaped hook 5 to be adjusted to suit different installation requirements. The second locking bolt 18 passes through the threaded holes 6 and abuts the T-shaped slider 17, securing the T-shaped slider 17 and preventing accidental movement of the second movable component 9.

[0043] In this embodiment, the fastening end 12 of the copper stranded wire portion 2 is fitted with an externally threaded sleeve 10, which is threadedly connected to the interior of the galvanized steel 3. A loose-strand fastener 11 is provided at the other end of the copper stranded wire portion 2. This fastener 11 prevents the copper stranded wire from loosening, maintaining structural integrity and electrical conductivity. The fastener 11 comprises a binding tape. The externally threaded sleeve 10 mates with the threads within the galvanized steel 3, securing one end of the copper stranded wire portion 2 and ensuring a secure connection.

[0044] Working principle:

[0045] This easy-to-construct copper stranded wire connector connects two L-shaped hooks 5 to the copper stranded wire portion 2 and the convenient hooking and clamping components 4 on the galvanized steel 3, respectively. The position of the L-shaped hook 5 is adjusted using the first movable component 8 and the second movable component 9 so that it can be accurately aligned with the grounding trunk line or natural grounding body to be connected. The L-shaped hook 5 is slid under the target object from the side, and the elastic deformation ability of the elastically upturned clamping end 15 is utilized to smoothly insert and secure the L-shaped hook to the target object. At this point, the hooking clamping portion 16 will fit tightly against the surface of the target object, providing stable mechanical support.

[0046] If further adjustment of the position of the L-shaped hook 5 is required, fine-tuning can be performed by moving the sliding sleeve 13 in the first movable component 8 or the T-shaped slider 17 in the second movable component 9. The sliding sleeve 13 is locked in place using the first locking bolt 14 to prevent it from sliding on the copper strand 2. For the second movable component 9, the T-shaped slider 17 is fixed in place by tightening the second locking bolt 18 in the threaded hole 6, ensuring that the L-shaped hook 5 does not move.

[0047] Insert one end of the copper stranded wire part 2 into the external threaded sleeve 10, and screw the external threaded sleeve 10 into the galvanized steel 3 to form a stable mechanical connection. An anti-loosening fastener 11 is set at the other end of the copper stranded wire part 2 to ensure the structural integrity of the copper stranded wire and avoid loosening due to external factors.
