[0040] like Figures 1 to 4 As shown, this embodiment provides a terminal block mounting structure and electrical equipment. The electrical equipment includes a body and a terminal block mounting structure. The terminal block mounting structure includes a guide rail 10, a terminal block assembly 20, and a fixing frame 30. The guide rail 10 is used to fix the electrical equipment body. The terminal block assembly 20 is slidably disposed on the guide rail 10. At least two sets of fixing frames 30 are provided. The fixing frame 30 includes a main body and a positioning member 33. The main body is connected to the guide rail 10 and is fixed to the guide rail 10 by the positioning member 33. The terminal block assembly 20 is sandwiched between the main bodies of two adjacent sets of fixing frames 30.

[0041] By fixing the guide rail 10 to the main body of the electrical equipment and installing a sliding terminal assembly 20 on the guide rail 10, the terminal assembly 20 can be easily slidably installed on the guide rail 10. Connecting the main body of the fixing bracket 30 to the guide rail 10 allows adjustment of the installation position of the terminal assembly 20 and the fixing bracket 30. Then, the positioning member 33 is used to fix the main body of the fixing bracket 30 to the guide rail 10. The terminal assembly 20 is clamped between two adjacent sets of fixing brackets 30, thus completely fixing the terminal assembly 20 to the guide rail 10. This effectively improves the installation convenience and flexibility of the terminal assembly 20 and can meet various usage requirements. The electrical equipment can be a transformer or reactor; the guide rail 10 can be fixed to the main body of the electrical equipment with bolts.

[0042] Specifically, the main body of the fixing frame 30 is fixed to the guide rail 10 by a positioning element 33. The positioning element 33 can be a bolt, which provides a stronger holding force through threaded engagement or mechanical preload, ensuring the stability of the fixing frame 30, providing good resistance to loosening, and allowing for repeated disassembly for easy assembly and maintenance. In other embodiments, the main body of the fixing frame 30 can also be fixed to the guide rail 10 by means of snap-fitting the positioning element 33 with the guide rail 10.

[0043] Furthermore, the main body of the fixing frame 30 includes a fixing base 31 and a limiting plate 32. The fixing base 31 is slidably disposed on the guide rail 10. The first end of the limiting plate 32 passes through the fixing base 31, and the second end of the limiting plate 32 abuts against the terminal assembly 20. The positioning member 33 passes through the limiting plate 32 and is threadedly connected to the fixing base 31, so that the first end of the limiting plate 32 abuts against the guide rail 10.

[0044] By setting a fixed base 31 and a limiting plate 32, the fixed base 31 is slidably set on the guide rail 10. The guide rail 10 initially limits the position of the fixed base 31. The second end of the limiting plate 32 abuts against the terminal assembly 20 to limit the terminal assembly 20. The first end of the limiting plate 32 passes through the fixed base 31. After the positioning member 33 passes through the limiting plate 32 and is threadedly connected to the fixed base 31, the positioning member 33 is tightened so that the first end of the limiting plate 32 abuts against the guide rail 10, so that the limiting plate 32 and the fixed base 31 cannot move relative to the guide rail 10, thereby fixing the terminal assembly 20.

[0045] Optionally, the guide rail 10 has side flanges 11 on both sides, and the fixing seat 31 has a first slot 311 corresponding to each side flange 11. The side flange 11 slides through the first slot 311. By providing side flanges 11 on the side edges of the guide rail 10, and matching the side flanges 11 with the first slots 311 on the fixing seat 31, the lateral offset between the fixing seat 31 and the guide rail 10 is limited, ensuring that the fixing seat 31 can only move along the extension direction of the guide rail 10 in the moving state. The structure is simple and reliable, and effectively prevents the fixing seat 31 from separating from the guide rail 10.

[0046] Optionally, the fixed seat 31 has an inverted U-shaped cross-section, and both ends of the bottom of the fixed seat 31 are slidably connected to the guide rail 10. The first end of the limiting plate 32 passes through the top of the fixed seat 31, and the positioning member 33 is threadedly connected to the top of the fixed seat 31. By setting the cross-section of the fixed seat 31 to an inverted U-shape and connecting both ends of the bottom of the fixed seat 31 to the guide rail 10, the stability of the sliding connection between the fixed seat 31 and the guide rail 10 can be ensured.

[0047] In this embodiment, the bottom of the fixing base 31 has two parallel and spaced fixing plates. Each fixing plate is provided with a first slot 311 for cooperating with the guide rail 10. The top of the fixing base 31 has a mounting surface 312, an insertion hole 313 and a threaded hole. The insertion hole 313 and the threaded hole penetrate the mounting surface 312. The positioning member 33 is threadedly engaged with the threaded hole on the top of the fixing base 31. The limiting plate 32 is partially inserted through the insertion hole 313 and inserted between the two fixing plates, thereby abutting against the guide rail 10.

[0048] Optionally, each fixing plate has two sets of first slots 311, each set including two first slots 311 spaced apart; wherein the two first slots 311 of the first set are located between the two first slots 311 of the second set. In this embodiment, the two side flanges 11 of the guide rail 10 respectively cooperate with the two first slots 311 of the second set. It can be understood that by setting the first slots 311 in different positions or by setting first slots 311 of different shapes, the fixing base 31 can be adapted to guide rails 10 of different shapes.

[0049] Specifically, the limiting plate 32 includes an insertion part 321, an installation part 322, and an abutment part 323. The insertion part 321 and the installation part 322 are both connected to the abutment part 323. The insertion part 321 passes through the fixed seat 31, and the abutment part 323 abuts against the terminal assembly 20. The positioning member 33 passes through the installation part 322 and is threadedly connected to the fixed seat 31, so that the insertion part 321 abuts against the guide rail 10, and the installation part 322 abuts against the fixed seat 31 and the fixed seat 31 abuts against the guide rail 10.

[0050] By providing the insertion part 321, the mounting part 322, and the abutment part 323, when the positioning member 33 is tightened, the abutment part 323 abuts against the terminal assembly 20 to limit the terminal assembly 20, the insertion part 321 abuts against the guide rail 10, and at the same time, the mounting part 322 abuts against the fixing seat 31, thereby causing the fixing seat 31 to also abut against the guide rail 10, further ensuring the stability of the fixing bracket 30 and reducing the possibility of the fixing bracket 30 loosening and shifting.

[0051] Optionally, the limiting plate 32 includes two insertion portions 321, which are spaced apart, and a mounting portion 322 is located between the two insertion portions 321. By spaced apart the two insertion portions 321 and providing the mounting portion 322 between them, the contact area between the limiting plate 32 and the guide rail 10 is increased, which helps to further enhance the stability of the fixing frame 30.

[0052] In this embodiment, the limiting plate 32 is an integral bent structure; the mounting part 322 abuts against the mounting surface 312 of the fixing seat 31; the fixing seat 31 is provided with two insertion holes 313 for matching with the two insertion parts 321, the insertion part 321 is plate-shaped, and the insertion hole 313 is a strip-shaped hole.

[0053] See Figure 2 , Figures 5 to 8 The terminal assembly 20 includes at least two terminal blocks 21, each terminal block 21 having a second slot 211. The side folded edge 11 slides through the second slot 211 of each terminal block 21, and the terminal block 21 is clamped between two adjacent sets of fixing brackets 30.

[0054] By providing a second slot 211 on the terminal block 21, and using the second slot 211 in conjunction with the side folded edge 11, the terminal block 21 can be slidably mounted on the guide rail 10, allowing different numbers of terminal blocks 21 to be flexibly combined and used.

[0055] Optionally, the terminal assembly 20 further includes a partition 22, which is fixed to the terminal block 21 and located between two adjacent terminal blocks 21. In this embodiment, the end of the partition 22 protrudes outward from the side of the terminal block 21. By providing a partition 22 between two terminal blocks 21, the two adjacent terminal blocks 21 can be isolated from each other, increasing the electrical clearance and creepage distance, and preventing short circuits during wiring.

[0056] Optionally, the terminal block 21 has a wiring space, with a side opening on one side of the terminal block 21. At least two positioning protrusions 212 are provided on the side of the terminal block 21, located at the outer edge of the side opening. The partition 22 has positioning holes 221 corresponding to the positioning protrusions 212, and the positioning protrusions 212 are inserted into the positioning holes 221. By setting the positioning protrusions 212 and positioning holes 221 to engage, the relative position of the partition 22 and the terminal block 21 can be limited, ensuring the stability of the partition 22's installation position.

[0057] In this embodiment, the terminal block 21 has a side opening on one side, and the partition 22 is fastened and fixed to the terminal block 21 and blocks the side opening of the terminal block 21; the positioning protrusion 212 of the partition 22 and the positioning hole 221 of the terminal block 21 are clearance-fitted or interference-fitted. In other embodiments, the partition 22 can be snapped onto the terminal block 21.

[0058] In this embodiment, the terminal assembly 20 further includes a connector 23 and a connector screw 24. The connector 23 is used for external wiring. The terminal block 21 is provided with a receiving groove 213 located in the wiring space. The connector 23 is disposed in the receiving groove 213 and extends in the horizontal direction. Both ends of the connector 23 are provided with connector screws 24. The bottom of the terminal block 21 is provided with a hook, and a second slot 211 is disposed on the hook.

[0059] In this embodiment, two sets of hooks are provided, each set including two hooks spaced apart; the two hooks of the first set are located between the two hooks of the second set, and each hook is provided with a second slot 211. The two side flanges 11 of the guide rail 10 respectively cooperate with the two hooks of the second set. It can be understood that the second slots 211 are set in different positions or have different shapes so that the terminal block 21 can be adapted to guide rails 10 of different shapes.

[0060] See Figure 2Multiple terminal blocks 21 are arranged side by side. The terminal block assembly 20 also includes an end plate 25, which is slidably mounted on the guide rail 10 and blocks the side opening of one of the outermost terminal blocks 21. The thickness of the end plate 25 is greater than the thickness of the partition plate 22. The fixing bracket 30 abuts against the terminal block 21 or the end plate 25. By setting the end plate 25, the terminal blocks 21 can be protected and deformed. In other embodiments, two end plates 25 can be set, and all terminal blocks 21 and partition plates 22 can be arranged between the two end plates 25.

[0061] The following is a detailed explanation of the usage process of the terminal block mounting structure:

[0062] The guide rail 10 is fixed to the body of the electrical equipment. Different numbers of terminal blocks 21 are installed on the guide rail 10 as needed, and a partition 22 is set between two adjacent terminal blocks 21. After the terminal assembly 20 is assembled, a fixing seat 31 is installed on the guide rail 10 so that the terminal assembly 20 is located between two fixing seats 31. The insertion part 321 of the limiting plate 32 is inserted into the insertion hole 313 of the fixing seat 31. At this time, the relative positions of the terminal assembly 20, the fixing seat 31, the limiting plate 32 and the guide rail 10 can be adjusted. Finally, the positioning member 33 is passed through the mounting part 322 of the limiting plate 32 and the positioning member 33 is screwed so that the positioning member 33 is threadedly connected to the fixing seat 31. After the positioning member 33 is tightened, the insertion part 321 of the limiting plate 32 abuts against the guide rail 10, and the mounting part 322 abuts against the mounting surface 312 of the fixing seat 31, so that the fixing seat 31 abuts against the guide rail 10, thus completing the installation of the terminal assembly 20 and the fixing bracket 30.
