Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown, a kind of leakage protection structure of breaker of plastic casing, including pedestal 1, electric leakage is installed in the pedestal 1
Buckle releaser 2, mutual inductor 3；1 bottom of pedestal offers line outlet groove 11 and three sampling holes 12, the line outlet groove 11 and three
Linear cabling channel 13 has been individually formed between a sampling hole 12；Protective shell 4, protective shell 4 are also equipped in the pedestal 1
It is inside provided with wiring board, the protective shell 4 is located at the side of mutual inductor 3, and the protective shell 4 is set on the side of mutual inductor 3
There is the first crossed beam trunking 41, the bottom surface of the protective shell 4 is equipped with second crossed beam trunking 42 corresponding with line outlet groove 11.
Leakage tripping device connects mutual inductor 3 by electric wire, and mutual inductor 3 enters protective shell from the first crossed beam trunking 41 by electric wire
The wiring board in protective shell 4 is connected in 4, the sample line on wiring board in protective shell 4 passes through the second crossed beam trunking 42, outlet hole again
11, cabling channel 13 extends to sampling hole, is attached by connection bolt.
Wiring board is arranged in protective shell 4, the effect of a sealing, protection is provided by protective shell 4, to greatly reduce ring
Influence of the border factor to wiring board, so as to effectively wiring board be avoided to damage, meanwhile, sample line is extend out to outside pedestal 1, along base
The independent cabling of each cabling channel 13 of 1 bottom of seat, is not only separated from each other sample line, avoids intersecting, effectively avoid sample line
Breakage, and the length of sample line is greatly reduced, reduce product cost.
As shown, the 42 lower end outer edge of the second crossed beam trunking is formed with positioning convex platform 43, the positioning convex platform 43 with
