[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] An embodiment of the present application provides a ground wire connector for a cable, which can solve the problem in the related art that when the ground wire is offset and shaken, it may cause back and forth friction between the ground wire end and the pin connection, resulting in loose connection, or even cause breakage at the ground wire end, which may cause electrical failure and pose a threat to the normal operation of the electrical system.

[0023] See also Figure 1-Figure 3 A grounding wire connector for a cable comprises: a base 1, a plurality of trays 2 are rotatably arranged on the base 1, a shell 3 is arranged on the tray 2, a closed cavity 4 is formed between the shell 3 and the tray 2, a wiring seat 5 is arranged inside the closed cavity 4, three groups of winding posts 6 are arranged inside the closed cavity 4, the winding posts 6 are used to wind the grounding cable, a lead tube 7 is rotatably arranged on the tray 2, the lead tube 7 is used to accommodate the grounding cable, a metal hose 8 is arranged at one end of the lead tube 7, the other end of the metal hose 8 is connected to the shell 3, and a sealing cover 9 is arranged on the shell 3.

[0024] The grounding cable is introduced through the lead tube 7 on the rotatable tray 2. The lead tube 7 not only provides a channel for the grounding cable, but also ensures the flexibility and adjustability of the cable during the introduction process. Then, the grounding cable enters the closed cavity 4 formed between the shell 3 and the tray 2 through the metal hose 8. The design of the metal hose 8 enables the cable to maintain a certain degree of curvature during the introduction process to adapt to different installation environments.

[0025] Inside the closed cavity 4, the grounding cable can be wound around the winding pole 6. By adjusting the cable winding method on the winding pole 6, the cables can be effectively fixed and organized to avoid clutter and mutual interference of the cables. After the grounding cable is fixed on the winding pole 6, it can be connected to the terminal block 5 to achieve reliable grounding of the ground wire.

[0026] The function of the sealing cover 9 is to ensure the sealing of the closed cavity 4 and prevent impurities such as water vapor and dust from entering the cavity, thereby protecting the internal wiring seat 5 and winding pole 6 and other components from erosion by the external environment.

[0027] During the entire working process, when the grounding cable shakes and deviates, the grounding wire connector can rotate along with the deflection direction of the grounding cable, and the grounding cable is wound on the winding column 6, ensuring the stability of the connection between the grounding cable connector and the terminal block 5, avoiding shaking and friction at the connection, and achieving a stable fixation and reliable grounding of the cable grounding cable. At the same time, its airtight and flexible design also improves the safety and construction efficiency of the grounding connection, providing strong support for the cable laying project.

[0028] Specifically, in this embodiment, a plurality of receiving grooves 10 adapted to the trays 2 are provided on the base 1 , and the trays 2 are rotatably disposed inside the receiving grooves 10 .

[0029] The receiving groove 10 provides an installation space for the tray 2 and ensures the stability and flexibility of the tray 2 on the base 1 .

[0030] Specifically, the wiring seat 5 in this embodiment includes a base, and a plurality of wiring pins are arranged on the base, and bolts are threadedly connected to the wiring pins.

[0031] The base serves as the basic supporting part of the terminal block, and the terminal pins are components used to connect to the grounding cable. Each terminal pin has a different shape and size to meet the connection requirements of different grounding connecting wires.

[0032] In this embodiment, the winding pole 6 is located between the wiring seat 5 and the lead tube 7, and the number of the winding poles 6 in a group is two.

[0033] The winding post 6 is located inside the enclosed cavity 4 and is arranged between the terminal block 5 and the lead tube 7. This layout design allows the grounding cable to be orderly wound through the winding post 6 after being introduced and then connected to the terminal block 5, ensuring the neatness of the cable and the stability of the connection.

[0034] Furthermore, the number of a group of winding poles 6 is two. This design not only meets the needs of cable winding, but also avoids the problem of space congestion and cable confusion caused by too many winding poles.

[0035] Furthermore, in this embodiment, a hinge seat 11 is provided on the tray 2, and the lead tube 7 is rotatably set on the hinge seat 11. A receiving hole 12 is opened on the top of the lead tube 7, and the receiving hole 12 is used for the grounding cable to extend into the lead tube 7.

[0036] It can be understood that in this embodiment, a hinge seat 11 is provided on the tray 2, and the lead tube 7 is rotatably set on the hinge seat 11. A receiving hole 12 is opened on the top of the lead tube 7, and the receiving hole 12 is used for the grounding cable to extend into the lead tube 7.

[0037] An articulated seat 11 is provided on the tray 2, so that the lead-in tube 7 can be flexibly rotated. Through the rotation connection of the articulated seat 11, the direction and position of the lead-in tube 7 can be adjusted to meet the actual needs of cable laying.

[0038] The top of the lead tube 7 is provided with a receiving hole 12, so that the grounding cable can smoothly extend into the lead tube 7. The shape and size of the receiving hole 12 match the grounding cable, ensuring that the cable can smoothly pass through without being damaged or stuck.

[0039] It can be understood that in this embodiment, rubber sleeves are provided inside the lead tube 7 and the metal hose 8, and the accommodating hole 12 of the lead tube 7 is provided at an obtuse angle.

[0040] Rubber sleeves are provided inside the lead-in tube 7 and the metal hose 8. The rubber sleeves can enhance the friction between the cable and the inner wall of the pipe, thereby preventing the cable from sliding or falling off inside the pipe, and improving the stability of the cable connection; the rubber sleeves also have a certain sealing performance, which can effectively prevent external impurities or water vapor from entering the pipe, further improving the reliability of the ground wire connector.

[0041] In addition, the present embodiment also designs the receiving hole 12 of the lead-in tube 7 to be an obtuse angle, so that the cable can enter the receiving hole more smoothly when introduced, reducing the friction and jamming of the cable at the entrance.

[0042] Specifically, in this embodiment, the housing 3 is provided with a plurality of insertion holes, and the bottom of the sealing cover 9 is provided with a plurality of insertion rods adapted to the insertion holes.

[0043] The jacks on the housing 3 are matched with the plug rods at the bottom of the sealing cover 9. When the sealing cover 9 is placed on the housing 3, the plug rods at the bottom thereof will be accurately inserted into these jacks, thereby realizing a tight connection between the sealing cover 9 and the housing 3, making the installation and removal process of the sealing cover 9 simple and convenient, and ensuring a stable and reliable connection between the sealing cover 9 and the housing 3. The tight fit between the plug rod and the jack can effectively prevent foreign impurities, water vapor, etc. from entering the closed cavity 4, thereby protecting the internal wiring seat 5 and winding pole 6 and other components from damage.

[0044] Among them, a plurality of ribs are arranged above the sealing cover 9 .

[0045] The ribs enhance the structural strength of the sealing cover 9, making it more durable. Under frequent opening and closing or external pressure, the ribs can effectively prevent the sealing cover 9 from being deformed or damaged, thereby ensuring the long-term stable operation of the grounding wire connector.

[0046] Secondly, the ribs also play an anti-skid role. When the construction personnel operate the sealing cover 9, the ribs can increase the friction of the hands, making the operation more convenient and accurate. Especially in a humid or greasy construction environment, the anti-skid effect of the ribs is more significant, reducing the safety risks caused by improper operation.

[0047] In addition, the rib design also has a certain heat dissipation function. The ground wire connector may generate a certain amount of heat during operation, and the ribs can effectively increase the surface heat dissipation area of ​​the sealing cover 9, improve the heat dissipation efficiency, and help maintain the normal working temperature of the ground wire connector.

[0048] The bottom of the base 1 in this embodiment is embedded with a bottom plate 13, and a guide rod 14 is arranged on the bottom plate 13. The top end of the guide rod 14 extends into the accommodating groove 10, and the tray 2 is rotatably arranged on the guide rod 14, wherein the guide rod 14, the terminal block 5, the tray 2 and the bottom plate 13 are all conductors.

[0049] The tray 2 is rotatably arranged on the guide rod 14 , so that the tray 2 is more stable and flexible when rotating, and also ensures a stable connection between the tray 2 and the base 1 .

[0050] In addition, the guide rod 14, the wiring seat 5, the tray 2 and the bottom plate 13 are all conductors. This design allows the entire card connector to form a good conductive path, ensuring the reliability and effectiveness of the ground connection. When the ground wire is connected to the card connector, the current can flow smoothly to the ground through these conductor components, achieving effective grounding protection.

[0051] The base 1 in this embodiment is made of insulating material.

[0052] The base 1 is made of insulating material, which can effectively isolate the current and prevent unnecessary electrical contact between the base 1 and other metal parts or the external environment, thereby greatly improving the safety of the grounding connector.

[0053] In addition, a number of fixing ears are provided on the base 1. The function of these fixing ears is to provide a more stable installation method for the ground wire connector. Through the fixing ears, construction personnel can easily fix the connector on the wall, bracket or other suitable position to ensure that it will not move or fall off due to external force during use.

[0054] It can be understood that in this embodiment, an insulating layer is provided at the top of the tray 2 and at the location outside the shell 3, and the shell 3 and the sealing cover 9 are both made of insulating materials.

[0055] This design ensures electrical isolation between the components of the grounding connector, prevents current leakage, and also makes the entire connector safer and more reliable during use.

[0056] The insulating layer can be a plastic patch layer or an insulating material.
