Embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
It is further described in detail, embodiments given below is not intended to be limiting of the invention only for illustrating the present invention
Scope.In the following description, it is necessary to which explanation, term " left side ", " right side " " top ", " bottom ", " transverse direction " etc. are indicated
Orientation or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of description the present invention and simplification retouch
State, rather than indicate or imply that the device or element of meaning there must be specific orientation, with specific azimuth configuration and operation,
Therefore it is not considered as limiting the invention.In addition, term " first ", " second " are only used for describing purpose, without being understood that
To indicate or implying relative importance.
As illustrated, a kind of RCCB, including pedestal 1, shell, the wherein side of the pedestal 1 takes off provided with short circuit
Buckle mechanism, including handle 3, connecting rod 7, tripping 8, lock 9, short-circuit release 10；The opposite side of the pedestal 1 is threaded off provided with electric leakage
Mechanism, including leakage tripping device 2, push rod 5, electric leakage indication piece 4；Described one end of push rod 5 is connected with leakage tripping device 2, separately
One end is connected with lock 9, and when leaking electricity, leakage tripping device 2 is acted, and drives lock 9 to unlock by push rod 5, is realized
Thread off.
The composition leakage, breaking as illustrated, the leakage tripping device 2, handle 3, electric leakage indication piece 4, push rod 5 cooperate
The electric leakage detector of device.
The handle 3 is hinged on the side of pedestal 1, and the handle 3 is provided with the positioning boss for extending to the opposite side of pedestal 1
31, for the deep-slotted chip breaker 11 of the activity of positioning boss 31 on the pedestal 1, when breaker is in the state that separating brake disconnects, handle 3
Positioning boss 31 is located at the tip position of deep-slotted chip breaker 11, when breaker is in the state for connection of closing a floodgate, the positioning boss of handle 3
31 are located at the bottom position of deep-slotted chip breaker 11.

Put, show normal condition.
As shown in Figure 3-4, the RCCB is in electric leakage off-state, and the electric leakage indication piece 4 is pushed to left lateral position
Put, while handle 3 resets, its positioning boss 31 is located at the tip position of deep-slotted chip breaker 11, can be by the positive stop lug boss 43 firmly
Ground is locked in the left side of positioning boss 31, ensure that electric leakage indication piece 4 correctly indicates leakage condition, relatively reliable stabilization.
As seen in figs. 5-6, the RCCB is in the separating brake off-state under non-drain conditions, and now leak electricity indication piece
4 keep right, while handle 3 resets, its positioning boss 31 is located at the tip position of deep-slotted chip breaker 11, can be by the jail of positive stop lug boss 43
The right side of positioning boss 31 is locked in firmly, can avoid, because leakage tripping device false tripping occur in larger vibrations, occurring indicating mistake
By mistake the problem of, indicate more accurately and reliably.
Above-mentioned electric leakage detector is relative to existing electric leakage detector, and number of parts is less, can not only simplify dress
Match somebody with somebody, while reducing cost；Additionally by mutual between the positive stop lug boss on the positioning boss on handle and electric leakage indication piece
Coordinate, the position locking of electric leakage indication piece, further increases the reliability that electric leakage is indicated when realizing different conditions.
As illustrated, the tapered structure in the bottom of positive stop lug boss 43, the pyramidal structure can play a guide effect, when
When handle 3 resets, its positioning boss 31 can slide to the side of positive stop lug boss 43 along taper surface,
As illustrated, the elastic component is spring 6, the driving boss 42 is provided with the spring stack 44 being adapted to spring 6,
Spring base 12 is correspondingly provided with the pedestal 1, described one end of spring 6 is set on spring stack 44 to offset with driving boss 42, separately
One end offsets with spring base 12.
Further, the spring base 12 is in horizontal U-shape structure, the upper side edge of the spring base 12 and pedestal 1 it is upper
Side is formed with indicating that block 41 is adapted to cunning
Embodiment is not construed as the limitation to invention, but any spiritual improvements introduced based on the present invention, all Ying Ben
Within the protection domain of invention.
