Technical Field

[0001] This utility model relates to the field of low-voltage switchgear technology, and in particular to a novel low-voltage switchgear copper busbar quick-connect socket device without drilling. Background Technology

[0002] Low-voltage switchgear, also known as low-voltage switch cabinet, is a device used for low-voltage power distribution in power systems. It is mainly used for controlling, protecting, and distributing electrical energy. Low-voltage switchgear mainly consists of a cabinet, insulating components, busbar system (copper busbars), cables, functional units, and door panels. The main function of low-voltage switchgear is to distribute power, distributing the voltage from the transformer to various power-consuming units. It is widely used in power plants, substations, industrial and mining enterprises, and other power users. The copper busbars of the low-voltage switchgear are conductive components used to connect low-voltage electrical appliances. Their main function is to connect the current between electrical appliances to ensure smooth circuit.

[0003] Because there are no sockets installed on the busbar (copper busbar), the low-voltage switchgear cannot be quickly connected to the emergency power generation vehicle. Therefore, in the event of equipment and line failures or power outages caused by other reasons, the goal of quickly restoring power cannot be achieved.

[0004] Therefore, a novel low-voltage switchgear-free copper busbar quick-connect socket device is proposed to solve the aforementioned problems. Utility Model Content

[0016] In a preferred embodiment, the two heat dissipation bars are arranged on both sides of the fixing screw a, both of which are made of stainless steel, and the L-shaped clamp is made of insulating material.

[0017] By adopting the above technical solution and using stainless steel material, fixing screw b and fixing screw a can have excellent corrosion resistance and are non-conductive.

[0018] In a preferred embodiment, a locking bolt is provided at one end of the copper busbar body, and conductive terminals are provided on both sides of the copper busbar body. The conductive terminals are connected to the copper busbar body by the locking bolt.

The copper busbar body 1 abuts between the two L-shaped clamping brackets 8. The socket is then installed... During installation, workers can use fixing screws a6 to pre-install the metal guide plate 5 below the metal conductor a4. Then, fixing screws b10 can be used to install two L-shaped clamps 8 on both sides of the metal guide plate 5. This allows the socket to be fixed by the force of the two L-shaped clamps 8. Users can adjust the fixing position of fixing screws b10 in the slide groove 9 according to the size of the copper busbar body 1 to suit different sizes of copper busbar bodies 1. This allows the new socket to be directly installed and fixed on the copper busbar body 1 without power interruption, without drilling holes in the copper busbar body 1, reducing power outages for users, improving power supply reliability, and enabling rapid assembly.

[0030] Specifically, a circular groove 16 is provided at the center of the bottom of the metal guide plate 5. A fixing screw a6 is threaded into the inside of the circular groove 16. By using the fixing screw a6, the metal guide plate 5 and the metal conductor a4 can be installed, thereby ensuring that the metal conductor a4 and the metal guide plate 5 are in close contact. The metal guide plate 5 and the metal conductor a4 are connected by the fixing screw a6. The top of the metal conductor a4 is provided with an anti-loosening component, which includes a slot 12 formed on the outer wall of the metal conductor a4 and an elastic buckle 11 at the top of the metal conductor a4. When the plug of the emergency generator is inserted into the metal conductor a4, the elastic buckle 11 can be engaged with the metal conductor a4. The slot 12 is engaged, which makes the plug of the emergency generator vehicle more stable during installation. The elastic buckle 11 engages with the inner wall of the slot 12. An insulating component is provided on the outside of the metal conductor a4. The insulating component includes a U-shaped insulating shell 2 that abuts between two L-shaped clamps 8. Through the cooperation of the U-shaped insulating shell 2 and the annular insulating shell 3, the metal conductor a4 and the metal guide plate 5 can be covered to prevent human contact with the metal conductor a4, thereby improving the power supply safety of the socket. The top of the U-shaped insulating shell 2 is fixedly connected to the annular insulating shell 3, which is sleeved on the outside of the metal conductor a4.

[0031] Specifically, the bottom of the metal guide plate 5 has two fixing grooves, and heat dissipation strips 14 are fixedly connected to the inner walls of the fixing grooves. Heat dissipation fins 15 are installed at equal intervals on the outer side of the heat dissipation strips 14. Through the cooperation of the heat dissipation strips 14 and heat dissipation fins 15, the heat dissipation area of ​​the metal guide plate 5 can be increased and the heat exchange efficiency can be improved. The two heat dissipation strips 14 are set on both sides of the fixing screw a6. The fixing screws a6 and b10 are both made of stainless steel.

At the same time, the fixing screw b10 is inserted into the slide groove 9, and the bottom end of the fixing screw b10 is threaded into the corresponding screw hole 7. At this time, the L-shaped clamp 8 can slide. Then, the metal guide plate 5 and the metal conductor a4 are placed on top of the copper busbar body 1. The user can adjust the fixing position of the fixing screw b10 in the slide groove 9 according to the size of the copper busbar body 1. After adjustment, the fixing screw b10 is tightened with a tool so that the L-shaped clamp 8 cannot slide. Then, the fixing screw b10 can be used to install the two L-shaped clamps 8 on the metal guide plate respectively. On both sides of 5, the two L-shaped clamps 8 can be used to fix the socket, so that the new socket can be directly installed and fixed on the copper busbar body 1 without power interruption, without drilling holes in the copper busbar body 1, reducing power outages for users. Then, the plug of the emergency generator is inserted into the metal conductor a4 and contacts the metal conductor b13. Then, the elastic buckle 11 is fastened to the slot 12, which makes the installation of the plug of the emergency generator more stable. Through the cooperation of the U-shaped insulating shell 2 and the annular insulating shell 3, the metal conductor a4 and the metal guide plate 5 can be covered to avoid human contact with the metal conductor a4, thereby improving the power supply safety of the socket.
