A cable body 1 is provided inside both the plug 2 and the socket 7. First hinge seats 3 are provided on both the plug 2 and the socket 7. Second hinge seats 10 are provided on both the plug 2 and the socket 7. The first hinge seats 3 and the second hinge seats 10 are symmetrically distributed along the axis of the tubes of the plug 2 and the socket 7. Connecting plates 4 are hinged on the first hinge seats 3. Through slots 11 are provided on the connecting plates 4. Hook plates 5 that are in an "L" - shaped structure and pass through the through slots 11 are hinged on the second hinge seats 10. Limit members for restricting the positions of the hook plates 5 are provided on the hook plates 5; The plug 2 and the socket 7 are inserted into each other. The cable body 1 is embedded in the plug 2 and the socket 7. The plug 2 and the socket 7 are made of polyamide material. The polyamide material has high mechanical strength and rigidity, can withstand large mechanical stresses, and ensures the stability and reliability of the plug 2 and the socket 7 during the insertion process; Polyamide has good electrical insulation performance, can effectively isolate current, prevent electric leakage and short - circuit, and ensure the electrical safety of the cable body 1; The polyamide material has good corrosion resistance to a variety of chemical substances, can maintain stable performance in harsh environments, and extend the service life of the cable connector; The polyamide material is easy to process and form, can manufacture plugs 2 and plugs 2 with complex shapes and high precision, and meet various connection requirements;

[0020] During production, a first hinge seat 3 is adhered to the surface of the plug 2, and a second hinge seat 10 is adhered to the surface of the plug 2. The first hinge seat 3 and the second hinge seat 10 are vertically distributed; a first hinge seat 3 is adhered to the surface of the socket 7, and a second hinge seat 10 is adhered to the surface of the socket 7. The first hinge seat 3 and the second hinge seat 10 are vertically distributed; the positions of the first hinge seat 3 and the second hinge seat 10 on the plug 2 correspond to the positions of the first hinge seat 3 and the second hinge seat 10 on the socket 7; when the plug 2 is inserted into the socket 7, the first hinge seat 3 and the second hinge seat 10 correspond to each other; a rotating shaft is hinged to both the first hinge seat 3 and the second hinge seat 10. A connecting plate 4 is adhered or welded to the rotating shaft on the first hinge seat 3, and a hook plate 5 with an "L" - shaped structure is welded or adhered to the rotating shaft on the second hinge seat 10. A through - slot 11 is formed in the connecting plate 4, and the hook plate 5 passes through the through - slot 11 to hook the connecting plate 4. A limiting member for restricting its position is provided on the hook plate 5. The limiting member includes a torsion spring. The torsion spring is sleeved on the rotating shaft of the second hinge seat 10. One end of the torsion spring is welded to the side wall of the hook plate 5, and the other end of the torsion spring is welded to the inner wall of the second hinge seat 10. When the torsion spring is in a natural state, the hook plate 5 passes through the through - slot 11 to hook the connecting plate 4. The hook plate 5 includes a vertical plate and a horizontal plate. The bottom of the vertical plate is welded or adhered to the rotating shaft of the second hinge seat 10, and the horizontal plate is welded to the top of the vertical plate. Rotate the hook plate 5 to drive the rotating shaft to rotate around the hinge point of the second hinge seat 10. When the vertical plate in the hook plate 5 rotates to a horizontal state, the hook plate 5 is located in the through - slot 11 of the connecting plate 4. At this time, the torsion spring deforms. When the hook plate 5 is released, under the torsional force of the torsion spring, the hook plate 5 is driven to rotate around the hinge point of the second hinge seat 10, causing the vertical plate of the hook plate 5 to rotate from the horizontal state to the vertical state. At this time, the hook plate 5 is located in the through - slot 11 and hooks the connecting plate 4, thereby fixing the connecting plate 4 and the hook plate 5 together, and then locking the insertion of the plug 2 and the socket 7, increasing the stability of the connection between the two, and preventing them from loosening or falling off during use, which may affect the safety of the circuit; during use, when the plug 2 is inserted into the socket 7, when the first hinge seat 3 and the second hinge seat 10 on the plug 2 correspond to each other, they can be rotated to make the first hinge seat 3 and the second hinge seat 10 correspond to each other, facilitating the connection of the plug 2 and the socket 7 and enhancing the connection firmness between the two;During installation, the first hinge seat 3 at the top of the plug 2 and the second hinge seat 10 at the top of the socket 7 are interconnected through a connecting plate 4 and a hook plate 5. The second hinge seat 10 at the bottom of the plug 2 and the first hinge seat 3 at the bottom of the socket 7 are interconnected through a connecting plate 4 and a hook plate 5. By staggering the connection of the first hinge seat 3 and the second hinge seat 10, the stability of the connection between the plug 2 and the socket 7 can be enhanced, preventing one of the connecting plates 4 and hook plates 5 from loosening due to accidental contact and affecting the stability of the connection between the plug 2 and the socket 7. Moreover, the connecting plate 4 is made of an elastic material, specifically an elastic band made of latex material. The elastic band made of latex material has a greater elongation and recovery force, enabling it to be stretched to the hook plate 5, providing a pulling force between the plug 2 and the socket 7 to enhance the connection stability. The latex material has good wear resistance and aging resistance, making the connecting plate 4 more durable and less likely to deform or be damaged even after long-term use, thus extending its service life as much as possible. Among them, the top of the plug 2 has a pulling force to the right, and the bottom of the socket 7 has a pulling force to the left. Through the staggered pulling forces of the two connecting plates 4, the plug 2 and the socket 7 are inserted more stably and firmly. During production, the size of the second hinge seat 10 is smaller than that of the first hinge seat 3, so that when the connecting plate 4 on the first hinge seat 3 rotates to the horizontal state, the hook plate 5 on the second hinge seat 10 can pass through the through slot 11 on the connecting plate 4 and hook it, making the plug 2 and the socket 7 inserted more stably.

[0021] As Figure 1 、 Figure 2 and Figure 3 shown, the limiting member includes a plug rod 6 fixed on the hook plate 5, and corresponding plug holes for inserting the plug rod 6 are provided on both the plug 2 and the socket 7. Among them, the plug rod 6 is welded or adhered to the bottom of the horizontal plate of the hook plate 5 at the top of the socket 7, and a plug hole is provided at the top of the socket 7 corresponding to the bottom of the plug rod 6. The bottom end of the plug rod 6 is inserted into the plug hole for mutual insertion. The plug rod 6 is welded or adhered to the top of the hook plate 5 at the bottom of the first hinge seat 3, and a plug hole is provided at the bottom of the plug 2 corresponding to the top of the plug rod 6. The top end of the plug rod 6 is inserted into the plug hole for mutual insertion. During use, the connecting plate 4 is rotated to the horizontal state around the hinge of the first hinge seat 3, the hook plate 5 passes through the through slot 11 on the connecting plate 4, the hook plate 5 hooks the connecting plate 4, and the connecting plate 4 is rotated to rotate around the hinge of the second hinge seat 10, so that the plug rod 6 on the hook plate 5 is inserted into the plug hole, and the two are mutually inserted, thereby connecting the connecting plate 4 and the hook plate 5, and further increasing the connection stability between the plug 2 and the socket 7. When it is necessary to loosen the plug 2 and the socket 7, just rotate the hook plate 5 to pull out the plug rod 6 from the plug hole, and then loosen the restraint of the hook plate 5 on the connecting plate 4, and the plug 2 and the socket 7 can be separated. The operation is simple and clear.

[0022] As Figure 1 、 Figure 2 and Figure 3As shown, a protective ring 9 is provided on the plug 2. The protective ring 9 is adhered to the insertion end of the plug 2. When the plug 2 is inserted into the socket 7, the protective ring 9 protects the connection between the plug 2 and the socket 7. The protective ring 9 can prevent the external environment from eroding the connection between the plug 2 and the socket 7, such as ultraviolet rays, corrosive substances, etc., thereby enhancing the durability of the plug 2 and the socket 7 and reducing damage or failures caused by environmental factors; there are grooves on the protective ring 9, and a sealing ring 8 is provided on the socket 7 and embedded in the grooves. The insertion end of the protective ring 9 is provided with grooves in a ring structure, and the sealing ring 8 is adhered to the insertion end of the socket 7. The sealing ring 8 is embedded in the grooves of the protective ring 9. Through the sealing ring 8 and the protective ring 9, the connection between the plug 2 and the socket 7 is in a sealed state, which can prevent impurities such as moisture and dust from entering the inside of the plug 2 and the socket 7, reduce the risk of electric leakage and short circuit, and at the same time ensure the stability and reliability of their connection and extend the service life of the plug 2 and the socket 7; good sealing helps to maintain the electrical performance inside the plug 2 and the socket 7; ensure the efficient transmission of signals and electric energy, and improve the operating efficiency of the power system; the protective ring 9 is made of rubber, and the sealing ring 8 is also made of rubber material. A tight seal is formed between the sealing ring 8 and the protective ring 9 made of rubber material, effectively preventing the external liquid or gas from flowing through the gap between the two. The sealing ring 8 and the protective ring 9 made of rubber material have good elasticity and durability, can maintain a stable sealing performance in various environments, have a long service life, and can resist various substances such as oils, fuels, solvents, and acids, and are suitable for environments with corrosive and acidic substances;

[0023] As Figure 2 and Figure 3 As shown, a number of evenly distributed heat dissipation fins 12 are provided on the surfaces of the plug 2 and the socket 7. The heat dissipation fins 12 are prior art. As a passive heat dissipation element, the main function of the heat dissipation fins 12 is to increase the heat dissipation area and improve the heat exchange efficiency, thereby effectively dissipating the heat generated by the plug 2 and the socket 7 during use; the heat dissipation fins 12 are usually made of metals with good thermal conductivity (such as aluminum or copper), and have the characteristics of light weight and easy processing; according to different designs, the heat dissipation fins 12 can be divided into various types, such as spiral fins, finned-tube fins, wavy fins, etc., to adapt to different heat dissipation requirements and use environments. These fins transfer the heat from the heat source to the surrounding environment through conduction and convection, ensuring the stable operation of the plug 2 and the socket 7 and extending their service life;

[0024] During actual use, the plug 2 and the socket 7 are plugged into each other. The connecting plate 4 is rotated to rotate around the hinge of the first hinge seat 3 to a horizontal state. The hook plate 5 is rotated to rotate around the hinge of the second hinge seat 10 so that it passes through the through groove 11 on the connecting plate 4 to hook the connecting plate 4. Under the action of the limiting member, the position of the hook plate 5 is fixed. A rightward pulling force is applied to the plug 2 through the connecting plate 4 on the plug 2, and a leftward pulling force is applied to the socket 7 through the connecting plate 4 on the socket 7, so as to make the connection between the plug 2 and the socket 7 more stable, preventing the plug 2 and the socket 7 from loosening or falling off during use and affecting the use of their cables.
