Leakage protector

A leakage protector, comprising:

• a protector device (2), pins (3), a bottom plate (4) and a elastic sheet (5), wherein the protector device (2) is disposed at an upper part of the bottom plate (4), the protector device (2) controls switching-off and switching-on of the leakage protector, and the pins (3) are disposed at a lower part of the bottom plate (4);
• the protector device (2) comprises a communication maintaining device (6), a communication device (7) and a locking device (8), and the locking device (8) is disposed between the communication maintaining device (6) and the communication device (7) and is configured to control disconnection and connection of the elastic sheet (5) and the pins (3);
• the locking device (8) comprises an elastic sheet pressing block (8a) and a locking deflector rod (8b), the locking deflector rod (8b) is movably hinged with a second support (64) disposed on the communication device (7) by a second pin shaft (31), and the elastic sheet pressing block (8a) is movably hinged with a first support (43) disposed in the middle position of the bottom plate (4) by a first pin shaft (21);
• wherein the locking device (8) comprises a latch (33), a movable pressing plate (34) and a hasp slide way (36), the latch (33), the movable pressing plate (34) and the hasp slide way (36) is provided on the locking deflector rod (8b)
• and a pressing block upper part (8c) and a pressing block lower part (8d), the locking device (8) comprises a hasp (24), a vertical fork groove (23) provided on the pressing block upper part (8c), a pressing rod (22) provided on the pressing block lower part (8d) and a pressing block spring (9), the pressing block upper part (8c) is hinged with the pressing block lower part (8d) by a first pin shaft (21), and the pressing block spring (9) in a compressed state is disposed between the pressing block upper part (8c) and the pressing block lower part (8d);
• when the pressing rod (22) abuts against the elastic sheet (5), an elasticity of the pressing block spring (9) enables the pressing rod (22) to maintain a stable action force against the elastic sheet (5), and the hasp (24) is configured to abut against the latch (33);
• the communication device (7) comprises a second iron core (72) extending transversely, and the second iron core (72) is in clamping fit with the vertical fork groove (23);
• the communication maintaining device (6) comprises a first iron core (62) disposed longitudinally, and the first iron core (62) is configured to be in magnetic adsorption fit with the movable pressing plate (34);
• when a power source is switched on, the second iron core (72) drives the elastic sheet pressing block (8a) to rotate by the vertical fork groove (23), so that the pressing rod (22) positioned at a bottom of the elastic sheet pressing block (8a) presses the elastic sheet (5) downward, and meanwhile, the hasp (24) slides upward along the hasp slide way (36);
• furthermore, in a process that the hasp (24) slides to abut against the latch (33), the movable pressing plate (34) continuously moves downward, and the movable pressing plate (34) is adsorbed and fixed by the first iron core (62);
• the communication maintaining device (6) is configured to fix a position of the locking deflector rod (8b) to enable the elastic sheet pressing block (8a) to be maintained in a pressed state and enable the elastic sheet (5) and the pins (3) to be maintained in a connected state, thereby realizing circuit switching-on;
• and
• when the power source is switched off, the communication maintaining device (6) stops working, the locking deflector rod (8b) is released, and the latch (33) is disengaged from the hasp (24) to enable the elastic sheet (5) to be disconnected from the pins (3), thereby realizing circuit switching-off.
