Description

Technical Field

[0001] This application relates to the field of auxiliary devices for power distribution lines, and in particular to a protective device for connection terminals. Background Technology

[0002] In some equipment of power distribution lines, terminals are used to connect to conductors, such as drop-out fuses and disconnect switches. Terminals increase the reliability of the connection between conductors and equipment. During the actual operation of power distribution lines, terminals are affected by environmental factors such as wind, rain, and sun exposure, as well as thermal expansion and contraction, which increases the risk of terminal breakage, burnout, and other failures over time.

[0003] Statistics show that in southern regions, over 9.5% of 10kV distribution line faults are caused by broken, burnt, or overheated terminals, impacting both the line failure rate and power supply reliability. Furthermore, in the event of a broken terminal, the conductor may detach from the equipment and fall, posing a risk of short-circuiting other metal structures or causing grounding faults, further increasing the maintenance workload for staff. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a connection terminal protection device to reduce the risk of terminal failure and enhance conductivity to achieve the effects of preventing power outage and breakage.

[0005] To achieve the above technical objectives, this application provides a connection terminal protection device applied to a wiring terminal, wherein the front end and rear end of the wiring terminal are respectively connected to a device and a wire, and includes: a connection plate;

[0006] The front end of the connecting plate is connected to the device;

[0007] The rear end of the connecting plate is connected to the wire;

[0008] The connecting plate has a bent structure so that the shape of the connecting plate can be adapted to the wiring terminal;

[0009] The connecting plate is located on the side of the terminal block and abuts against the terminal block;

[0010] The connecting plate has a conductive structure.

[0011] Furthermore, the rear end of the connecting plate is provided with two connecting pieces;

[0012] The two connecting pieces form a C-shaped groove structure, and the two connecting pieces cover the wires connected to the rear end of the terminal block.

[0013] Furthermore, a flat plate is provided at the front end of the connecting plate;

[0014] The flat plate connects to the device and abuts against the terminal block.

[0015] Furthermore, it also includes wire clips;

[0016] The clamp covers the outer periphery of the connecting piece to press the connecting piece and the wire at the rear end of the terminal block together.

[0017] Furthermore, the wire clamp is a copper sheet.

[0018] Furthermore, the wire clamp is pressed against the outer periphery of the connecting piece by a clamp.

[0019] Furthermore, the width of the connecting plate is greater than the width of the wiring terminal.

[0020] Furthermore, the connecting plate is a copper-aluminum composite plate.

[0021] Furthermore, the layer of the connecting plate away from the terminal block is made of copper, and the layer near the terminal block is made of aluminum.

[0022] Furthermore, the thickness of the connecting plate is greater than or equal to 3 mm.

[0023] As can be seen from the above technical solutions, this application provides a connection terminal protection device applied to a wiring terminal. The front end and rear end of the wiring terminal are respectively connected to a device and a wire, including: a connecting plate; the front end of the connecting plate is connected to the device; the rear end of the connecting plate is connected to the wire; the connecting plate has a bent structure so that the shape of the connecting plate is adapted to the wiring terminal; the connecting plate is located on the side of the wiring terminal and abuts against the wiring terminal; the connecting plate has a conductive structure.

[0024] The connection terminal protection device provided in this solution can use the same connection method as the wiring terminal and abut against the side of the wiring terminal to protect and support it, thereby increasing the wiring terminal's resistance to mechanical stress and reducing the risk of breakage due to environmental factors or natural factors such as thermal expansion and contraction. At the same time, since the connection plate is a conductive structure, it can enhance the conductivity when the wiring terminal is operating normally. When the wiring terminal fails and breaks, the connection plate can serve as a temporary power connection, preventing the wire from falling off the equipment and maintaining the electrical connection between the wire and the equipment, thereby reducing the maintenance workload of the staff and ensuring the reliability of power supply.

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0032] Please see Figure 1The present application provides a connection terminal protection device, which is applied to a wiring terminal. The front end and the rear end of the wiring terminal are respectively connected to the device and the wire, including: a connection plate 10.

[0033] Corresponding to the connection method of the terminal block, the front end of the connecting plate 10 is connected to the device, and the rear end of the connecting plate 10 is connected to the wire. The connecting plate 10 is located on the side of the terminal block and abuts against the terminal block, which can support the terminal block to improve its resistance to mechanical stress and enhance its conductivity, thereby reducing the risk of damage to the terminal block caused by external forces. Therefore, it can reduce the possibility of the terminal block breaking or burning out due to external forces.

[0034] Meanwhile, in this embodiment, the connecting plate 10 has a bent structure, so that the shape of the connecting plate 10 is adapted to the wiring terminal. Optionally, as... Figure 1 As shown, the middle part of the connecting plate 10 is bent to form a bending groove 13; the middle part of the terminal block generally has a cylindrical main body structure; in this embodiment, the main body structure in the middle of the terminal block can be placed into the bending groove 13 and fit against the connecting plate 10, so that the terminal block and the connecting plate fit more tightly, ensuring that the connecting plate 10 can provide multi-point support for the terminal block, thereby enhancing the stability and reliability of the overall structure. When the terminal block is subjected to external force impact from environmental factors or internal impact due to thermal expansion and contraction, the connecting plate 10 can disperse some of the stress, thereby enhancing the terminal block's resistance to mechanical stress and reducing the vibration of the terminal block and the risk of deformation of the terminal block.

[0035] Therefore, after configuring the protective device provided in this embodiment, the tensile and compressive strength of the terminal block can be effectively improved, thereby increasing the service life of the terminal block, reducing the failure rate caused by terminal block breakage or burnout, thereby reducing maintenance costs and improving power supply stability.

[0036] Based on the above, in this embodiment, the connecting plate 10 is a conductive structure. The conductive connecting plate 10 increases the contact area between the wire and the device, thereby enhancing the current carrying capacity and reducing the possibility of the terminal block burning out due to overheating. Simultaneously, in the event of a terminal block breakage, the connecting plate 10 provides connection and conductivity, ensuring circuit continuity, preventing circuit interruptions caused by terminal block breakage, and preventing wires from falling off due to terminal block breakage and causing wider-ranging faults.

[0037] During subsequent maintenance, staff only need to disassemble the connection plate 10 and replace it with a new terminal block or replace both the terminal block and the connection plate 10. This eliminates the need for complex repair operations, thus simplifying the maintenance process and saving time and labor costs.

[0038] As one implementation, the front end of the connecting plate 10 may be provided with a through hole, through which it can be installed together with the wiring terminal on the connecting post of the device, thereby making the connection between the wiring terminal and the connecting plate 10 more secure.

[0039] In a more specific embodiment, the rear end of the connecting plate 10 is provided with two connecting pieces 11; the two connecting pieces 11 form a C-shaped groove structure, and the two connecting pieces 11 cover the wires connected to the rear end of the terminal block.

[0040] In practical applications, the front end of the wire is connected to the rear end of the terminal block; the front end of the wire is generally configured with a stripped structure; the terminal block is sleeved on the front end of the wire. In this embodiment, the two connecting pieces 11 can cover the wire connected to the rear end of the terminal block, ensuring a tighter connection between the wire, the terminal block, and the connecting plate, preventing loosening.

[0041] Furthermore, the connecting piece 11, which forms a C-shaped groove structure, facilitates installation, making it easier to insert the wire between the two connecting pieces 11. Afterwards, workers can use pliers to press the two connecting pieces 11 together, ensuring a tight fit between the connecting piece 11 and the terminal block and wire.

[0042] It should be noted that in this embodiment, the way of setting the connecting piece 11 at the rear end of the connecting plate 10 makes it easy for workers to operate with pliers, and has the characteristics of simple operation and high efficiency.

[0043] In one embodiment, the front end of the connecting plate 10 is provided with a flat plate 12; the flat plate 12 connects to the device and abuts against the wiring terminal.

[0044] The flat plate 12 has a flat, sheet-like structure that can fit the front end of the terminal block, increasing the contact area between the connecting plate 10 and the equipment and terminal block; and improving the stability of the connection between the connecting plate 10 and the terminal block and equipment.

[0045] Furthermore, after connecting the equipment and the terminal block, the flat plate 12 can serve as a gasket structure for the terminal block, providing a buffering effect, reducing wear on the terminal block caused by vibration or pulling, extending its service life, and further improving the reliability and safety of the power supply system.

[0046] In one embodiment, see Figure 1 and Figure 2 The connection terminal protection device provided in this embodiment also includes a wire clamp 20; the wire clamp 20 covers the outer periphery of the connection piece 11 to press the connection piece 11 and the wire at the rear end of the connection plate 10 together.

[0047] The wire clamp 20 can form a tight outer peripheral fixing structure on the outer periphery of the connecting plate, thereby further ensuring the stable connection between the connecting plate, connecting piece 11 and the terminal and wire, and preventing loosening due to vibration or pulling.

[0048] Optionally, the wire clamp 20 can be a C-shaped ring structure, which makes it easy to fit onto the outer periphery of the rear end of the connecting plate 10, that is, the outer periphery of the connecting piece 11.

[0049] As one implementation method, the wire clamp 20 is a copper sheet, which is easy to operate, allowing the operator to press the wire clamp against the outer periphery of the connecting piece 11 using pliers carried by them.

[0050] In application, the width of the connecting plate 10 is greater than the width of the terminal block to ensure that the connecting plate 10 can provide support and protection for the terminal block from at least one side.

[0051] As one implementation method, the connecting plate 10 is a copper-aluminum composite plate, which has good electrical conductivity, compressive strength and tensile strength.

[0052] In one embodiment provided in this application, the layer of the connecting plate 10 away from the terminal is made of copper, and the layer closer to the terminal is made of aluminum. Specifically, the connecting plate 10 consists of two layers. Figure 1 The right side of the connector plate 10 is made of aluminum, and the left side is made of copper. This makes the parts of the connector plate 10 that contact the wires and terminals made of aluminum. The aluminum material matches the material of the wires, reducing electrochemical reactions, preventing copper and aluminum oxidation, effectively preventing contact point corrosion, and enhancing the durability of the connection.

[0053] Optionally, the thickness of the connecting plate 10 is greater than or equal to 3 mm. In practical applications, the inventors have found that a connecting plate 10 with a thickness greater than or equal to 3 mm can meet the load-bearing requirements of the terminal blocks, ensuring connection stability and preventing breakage.

[0054] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
