Embodiment 1
[0020] see Figure 1 to Figure 8 , Embodiment 1 provided by the present invention: a high-efficiency current-limiting power distribution switch for power distribution terminals, including a main switch 1; the main switch 1 has a large volume and is locked and installed in the middle of the half part of the backboard of the electric box. And the main switch 1 is connected to an external power supply; the main switch 1 includes a cross brace shaft 102, and two cross brace shafts 102 are symmetrically fixed on the toggle handle of the main switch 1; a connecting rod 103, two cross brace shafts 102 There is a connecting rod 103 connected to the head ends; the main switch 1 includes a strip cover 104, and there is a strip cover 104 on the three wiring grooves at the top of the main switch 1 by pressing the locks at two places on the left and right to tighten the cover. , the main switch 1 is the main switch of the power supply of the entire electric box, the top junction slot is al...
Embodiment 2
[0023] see Figure 9 , Embodiment 2 provided by the present invention: a high-efficiency current-limiting power distribution switch for power distribution terminals, including a poking rod 4, which includes a sliding sleeve 401, and the rear side of the top end section of the two poking rods 4 is welded and fixed with two sliding sleeve 401, the two sliding sleeves 401 are corresponding to the two hexagonal vertical support shafts 101 for sliding fit, and the tail ends of the two connecting rods 103 are correspondingly connected to the two sliding sleeves 401 in rotation, and the two connecting rods 103 , two sliding sleeves 401, two poking rods 4 and two cross brace shaft rods 102 are jointly connected to form a double crank slider mechanism. When switching between on and off, it can push and drive the two poking rods 4 to slide up and down to control the swing cover 3 on the main switch 1 to turn over and open. The force rod 601 pushes and contacts and presses to drive the ...
Embodiment 3
[0024] see Figure 10, Embodiment 3 provided by the present invention: a high-efficiency current-limiting power distribution switch for power distribution terminals, including, the vertical rack 6 includes an L-shaped force rod 601, and the rear side of the middle section of the vertical rack 6 is welded and supported There is an L-shaped force rod 601, and the bottom sections of the two poking rods 4 slide down to push and contact the two L-shaped force rods 601 installed on the middle current limiting switch 2. When the toggle handle of the main switch 1 is in the upper position In the upturned state, when all the switches are in the energized state, all the swing cover plates 3 can be engaged and placed in a drooping closed state to shield the wiring groove to avoid accidental touches. When the toggle handle of the main switch 1 is in the downward tilted state, all When it is in the power-off state, the two poking rods 4 can be pushed down to drive all the swing cover plate...
