Embodiment 1
[0053] Such as Figure 4-Figure 7 The shown embodiment 1 of a crown spring installation structure with good positioning and easy disassembly of the present invention includes a crown spring 1 and a sleeve 2 sleeved on the crown spring 1, and the crown spring 1 is close to both ends. A plurality of elastic flaps 3 are evenly distributed on the outer circular surface in the circumferential direction. The elastic flaps 3 are the plate surfaces of the crown spring 1 that are turned outward. The folding plates 3 are arranged in the through holes 4 in one-to-one correspondence; the folding directions of the elastic folding plates 3 at both ends of the crown spring 1 are set in opposite directions, and the free ends of the elastic folding plates 3 are all against the holes of the through holes 4 on the wall.
[0054] When installing, press the elastic flap 3 at one end of the crown spring 1, so that the crown spring 1 is inserted into the sleeve 2, and the crown spring 1 is set in t...
Embodiment 2
[0062] Such as Figure 4 , 5 , 6, 8 and 9 show a second embodiment of a crown spring installation structure with good position-limiting and convenient disassembly of the present invention. The difference between this embodiment and the first embodiment is that the inner sleeve 2 The circular surface is provided with a first protrusion 6 in the circumferential direction, and the elastic expansion section of the reed of the crown spring 1 fits on the first protrusion 6 when it is in a tension limit state.
[0063] The elastic expansion section is a concave radial elastic expansion and contraction part in the middle of the reed of the crown spring 1 . After the pin 8 is inserted, in this embodiment, the reed of the crown spring 1 is under pressure, so that the reed can be directly attached to the first protrusion 6 of the sleeve 2, which shortens the transmission path of the energized current and reduces Volume resistance, reduce heat generation, increase current carrying capac...
Embodiment 3
[0070] Such as Figure 4 , 5, 6, 10 and 11 show a third embodiment of a crown spring installation structure with good position limiting and easy disassembly of the present invention. The difference between this embodiment and embodiment 1 is that each crown spring 1 The outer surface of the reed is provided with a second protrusion 7 in the shape of a boss. When the elastic relaxation section of the reed of the crown spring 1 is in the tension limit state, each second protrusion 7 is attached to the sleeve 2 on the inner wall.
[0071] The elastic expansion section is a concave radial elastic expansion and contraction part in the middle of the reed of the crown spring 1 . After the pin 8 is inserted, the second protrusion 7 on the reed of this embodiment can be directly attached to the inner wall of the sleeve 2 when the reed of the crown spring 1 is under pressure, shortening the transmission path of the energized current , Reduce volume resistance, reduce heat generation,...
