DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following specifically introduces the present utility model in combination with the attached drawings and specific embodiments.

[0017] The device for reducing the temperature rise of electrical connectors with low-melting-point materials, such as Figures 1 - 3As shown in the figure, it includes a base 1. There are two bases 1, and each base 1 is provided with mounting holes connected to the distribution box. A ceramic insulating sleeve 2 is connected to each base 1. A busbar copper row 3 is slidably connected between the ceramic insulating sleeves 2. The busbar copper row 3 and the ceramic insulating sleeves 2 are fixed with first locking bolts 201. The busbar copper row 3 includes a first connection through hole 301. Seven first connection through holes 301 are provided on the front sides of the upper and lower parts of the busbar copper row 3. Every two adjacent first connection through holes 301 up and down are a group, and there are 14 first connection through holes 301 in total. A bending part 302 is connected to the right side of the busbar copper row 3. Second connection through holes 303 that are symmetric left and right are provided on the upper and lower parts of the bending part 302. A protruding part 304 is connected to the left side of the busbar copper row 3. A concave part 305 is connected to the protruding part 304. Fourteen positioning strips 306 are connected to the front side of the busbar copper row 3. Every two positioning strips 306 are a group, and each group of positioning strips 306 is distributed on the left and right sides of each group of first connection through holes 301. A connecting copper row 5 is slidably connected between each group of positioning strips 306. The connecting copper row 5 is of a Z-shaped structure. The connecting copper row 5 and the busbar copper row 3 are fixed with second locking bolts 501. A small low-melting-point alloy sheet 4 is arranged between the connecting copper row 5 and the busbar copper row 3. The small low-melting-point alloy sheet 4 is in contact with the busbar copper row 3 and the connecting copper row 5. The slot holes on the small low-melting-point alloy sheet 4 coincide with the first connection through holes 301. A large low-melting-point alloy sheet 6 is connected to the concave part 305.

[0018] The temperature rise of an electrical joint refers to the local heating phenomenon caused by the current passing through the joint during the operation of the circuit. This temperature rise may affect the safety and stability of electrical equipment and even pose a fire hazard. There are usually gaps between electrical joints, which are prone to moisture absorption or oxidation and corrosion of the electrical joints due to electrochemical reactions. Using a low-melting-point material can reduce the temperature rise of the electrical joint. Through its fusing characteristics, it can protect the circuit and equipment from overload or abnormal current, reduce heat generation defects, and effectively prevent safety hazards caused by overheating of the electrical joint. Connect the device to the distribution box through the mounting holes on the base 1. Install the small low-melting-point alloy sheet 4 between the busbar copper row 3 and the connecting copper row 5 through the second locking bolt 501. When the temperature of the electrical joint is too high, the small low-melting-point alloy sheet 4 fills the gap between the busbar copper row 3 and the connecting copper row 5 through its fusing property, thereby preventing moisture absorption of the electrical joint and electrochemical reaction from corroding the copper row, reducing heat generation defects, and further improving the safe operation level of the power grid. The positioning strip 306 contacts the small low-melting-point alloy sheet 4, which can increase the heat absorption area of the small low-melting-point alloy sheet 4, thereby accelerating the melting speed of the small low-melting-point alloy sheet 4. At the same time, it locates and limits the position after the small low-melting-point alloy sheet 4 melts, enhancing the filling effect of the small low-melting-point alloy sheet 4 on the gap of the electrical joint. When a longer busbar copper row 3 is required, the large low-melting-point alloy sheet 6 can be installed in the concave part 305. Then, the bent part 302 on the busbar copper row 3 is attached to the protruding part 304 and fixed with bolts, thereby extending the length of the busbar copper row 3 to meet the installation requirements of electrical joints with different lengths.

[0019] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
