DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-4 The utility model provides a technical solution: a miniaturized soft connection for an outdoor high-voltage vacuum circuit breaker, comprising a first copper conductive block 1, a first silver sheet 2, a first connecting belt 3, a mounting block 4, a mounting groove 5, a spring 6, a protrusion 7, a first protective pad 8, a first connecting port 9, a round hole 10, a second copper conductive block 11, a second silver sheet 12, a second connecting belt 13, a third copper conductive block 14, a second protective pad 15, a connecting block 16, a second connecting port 17, a first protective film 18, a second protective film 19 and a rubber layer 20. When the miniaturized soft connection for an outdoor high-voltage vacuum circuit breaker is used, Figure 1, using polymer diffusion welding equipment, the lower end of the first copper conductive block 1 is welded to the first silver sheet 2, the lower end of the first silver sheet 2 is welded to the upper end of the first connecting belt 3, and then the lower end of the first connecting belt 3 is welded to the first silver sheet 2, the right end of the lower first silver sheet 2 is welded to the left end of the second copper conductive block 11, the second silver sheet 12 is welded to the right end of the second copper conductive block 11, and the lower end of the second connecting belt 13 is welded to the right end of the lower second silver sheet 12;
[0026] Finally, the upper end of the second connecting belt 13 is welded to the second silver sheet 12, and the upper end of the second silver sheet 12 on the upper side is welded to the lower end of the third copper conductive block 14. The first copper conductive block 1, the first connecting belt 3, the second copper conductive block 11, the second connecting belt 13 and the third copper conductive block 14 are welded together through the first silver sheet 2 and the second silver sheet 12, ensuring that they will not fall off after welding, thereby making the installation method more secure, making the loop resistance smaller, and the conductive performance better;
[0027] like Figure 1 , Figure 2 and Figure 4 , since the protective structure includes the mounting block 4, the mounting groove 5, the spring 6, the protrusion 7, the first protective pad 8, the first connecting port 9, the connecting block 16 and the second connecting port 17, the sum of the thickness of the protrusion 7 and the minimum contraction length of the spring 6 is equal to the depth of the mounting groove 5, and the protrusion 7 and the mounting groove 5 constitute a lifting structure, so the protrusion 7 is pressed to make it completely drop into the inside of the mounting groove 5, and the first protective pad 8 is respectively attached to the left and right ends of the first connecting belt 3, so that the mounting block 4 on the first connecting belt 3 is engaged and connected to the inside of the first connecting port 9, and the connecting block 16 is engaged and connected to the inside of the second connecting port 17;
[0028] Loosen the protrusion 7 and let the spring 6 drive the protrusion 7 to rise, so that the upper end of the protrusion 7 protrudes from the upper end of the installation groove 5, while the middle and lower ends of the protrusion 7 continue to remain in the installation groove 5, and the position of the first protection pad 8 on the first connecting belt 3 is limited by the protrusion 7, and the second protection pad 15 is placed on the left and right ends of the second connecting belt 13 respectively, so that the mounting block 4 on the second connecting belt 13 is snap-connected to the inside of the first connecting port 9, and the connecting block 16 is snap-connected to the inside of the second connecting port 17, and the position of the second protection pad 15 on the second connecting belt 13 is limited by the protrusion 7, so that the first protection pad 8 and the second protection pad 15 protect the first connecting belt 3 and the second connecting belt 13, thereby preventing the soft connection from being worn;
[0029] like Figure 1 and Figure 2Since the waterproof structure includes a first protective film 18, a second protective film 19 and a rubber layer 20, the lengths of the first protective film 18 and the second protective film 19 are equal to the length of the rubber layer 20, so the first protective film 18 and the second protective film 19 are fixedly connected to the left and right ends of the rubber layer 20 respectively, and the second connecting belt 13 and the first connecting belt 3 are made of the same material, so the second connecting belt 13 and the second connecting belt 13 are also composed of the first protective film 18, the second protective film 19 and the rubber layer 20. The first protective film 18 and the second protective film 19 prevent rainwater from penetrating into the rubber layer 20, and waterproof the first connecting belt 3 and the second connecting belt 13. The circular holes 10 arranged at equal intervals on the second connecting belt 13 and the first connecting belt 3 can allow the first connecting belt 3 and the second connecting belt 13 to dissipate heat, thereby preventing the protective structure from being soaked by rainwater and causing damage. This is the working principle of the miniaturized soft connection of the outdoor high-voltage vacuum circuit breaker.
