    Device integrating an electric leakage test button with an electric leakage reset button of a leakage circuit breaker Technical field of the invention The invention relates to a device integrating electric leakage test with electric 5 leakage reset of a leakage circuit breaker, and in particular to a device integrating an electric leakage test button with an electric leakage reset button of a leakage circuit breaker with a function of protecting dual-breakpoint. Background of the invention Most of the current leakage circuit breakers only have test buttons. For the 10 leakage circuit breaker with a larger size, such as Schneider C65Vigi63A and CHINT DZ471e products, the test buttons and reset indicator buttons of these products are independent and separate, and are complex in structure and large in size, and cannot be applied in the electric leakage products with a smaller size. Summary of the invention 15 The technical problem to be solved by the invention is to provide a device integrating an electric leakage test button with an electric leakage reset button of a leakage circuit breaker. In order to solve the above technical problems, the invention provides a device integrating an electric leakage test button with an electric leakage reset button of a 20 leakage circuit breaker. The leakage circuit breaker comprises a frame body, a test circuit occurring in a leakage simulation, an operating handle, a test and reset button, a test and reset spring, an electric leakage lock, an electric leakage lock spring, a shaft, a test conductive spring and a brass tube. The part of the test and reset button higher than the frame body is provided with an upper layer and a lower layer, the upper layer 25 is T-layer surface part for the electric leakage test and electric leakage reset operation; the lower layer is R-layer surface part, which is provided with an indication of electric leakage status; the test and reset button is curved in the lower part and protrudes to form a snap-in part in the bottom, the snap-in part is in a snap-in linkage with an edge-protruding buckling part of the electric leakage lock; and the test circuit 1 occurring in the leakage simulation has a function of disconnecting and protecting dual-breakpoint. The R-layer surface part is parallel to the frame body, indicating that there is no electric leakage, which is in a normal working status; the electric leakage test of the test and reset button is achieved in such a way that the test and reset button 5 forces one end of the test conductive spring to be in contact with the brass tube, and the electric leakage reset of the test and reset button is achieved in such a way that it is linked with the electric leakage lock through the test and reset button. The test and reset button is provided with a spring groove in the middle part, and a reset spring is assembled in the spring groove. 10 The upper part of the electric leakage lock is provided with an edge-protruding buckling part, the edge-protruding buckling part is in a snap-in linkage with a buckling part of the test and reset button, the middle part of the electric leakage lock is provided with a circular through-hole into which a shaft is inserted for rotation, and the lower part of the electric leakage lock is provided with a circular protruding part 15 for beating a lock catch. When an electric leakage occurs, the action of a release causes the electric leakage lock to rotate clockwise, and the circular protruding part in the lower part beats the lock catch of the leakage circuit breaker so that the lock catch is separate from a jump button for protecting from the electric leakage; meanwhile, the edge-protruding buckling part in the upper part of the electric leakage lock is 20 detached from the buckling part in the bottom of the test and reset button, forcing the circular protruding part in the lower part of the electric leakage lock to be pushing the lock catch of the leakage circuit breaker to turn on the jump button of the leakage circuit breaker all the time and also enabling the switch to be in an off-state which cannot be turned on all the time. The switch can work normally only by pressing the 25 test and reset button so as to remove the effect of the electric leakage lock. The lower part of the handle is provided with an arc protruding part, the protruding part of the handle forces the test conductive spring to be in contact with the brass tube when the leakage circuit breaker is in a state of switching on, and the contact keeps switched off when the leakage circuit breaker is in a state of switching 30 off. 2 The test circuit occurring in the leakage simulation has a function of disconnecting and protecting dual-breakpoint, the test and reset button drives the test conductive spring to be in contact with the brass tube in the leakage test circuit so as to form a breakpoint, and the other breakpoint is formed in such a way that the 5 protruding part of the handle forces the test conductive spring to be in contact with the brass tube in the power supply line of the electronic circuit board. The excellent effects of the invention lie in the fact that: 1) Different functions of the test and reset button can be achieved by the suspending and moving changes of the test and reset button; when the test and reset 10 button is in a high position, it indicates that the leakage circuit breaker is in an electric leakage state; when the test and reset button is in a middle position, it indicates that the leakage circuit breaker is in a normal state; and when the test and reset button moves downward to a certain position, the reliability of the action of detecting the electric leakage protection can be reached that the simulation current flows through 15 the test circuit. 2) The characteristics that the invention integrates the test button with the reset indicator button are that it has a simple structure and a small size, is able to be applied in the leakage circuit breaker with a small size, and is capable of avoiding being burnt out when the inlet and outlet wirings fail through a breakpoint protecting circuit board 20 of the protruding part of the handle.

The invention provides a device integrating an electric leakage test button with an electric leakage reset button of a leakage circuit breaker. The leakage circuit 30 breaker comprises a frame body, a test circuit occurring in a leakage simulation, an 4 operating handle 3, a test and reset button 1, a test and reset spring 2, an electric leakage lock 4, an electric leakage lock spring 6, a shaft 8, a test conductive spring 9 and a brass tube. The part of the test and reset button 1 higher than the frame body is provided with an upper layer and a lower layer, the upper layer is T-layer surface part 5 101 for the electric leakage test and electric leakage reset operation; the lower layer is R-layer surface part 102, which is provided with an indication of electric leakage status; the test and reset button 1 is curved in the lower part and protrudes to form a snap-in part 104 in the bottom, the snap-in part 104 is in a snap-in linkage with an edge-protruding buckling part 401 of the electric leakage lock; and the test circuit 10 occurring in the leakage simulation has a function of disconnecting and protecting dual-breakpoint. The R-layer surface part 102 is parallel to the frame body, indicating that there is no electric leakage, which is a normal working status; the electric leakage test of the test and reset button 1 is achieved in such a way that the test and reset button 1 forces one end of the test conductive spring 9 to be in contact with the brass 15 tube A5, and the electric leakage reset of the test and reset button 1 is achieved in such a way that it is linked with the electric leakage lock 4 through the test and reset button 1. The test conductive spring 9 is formed into a structure of a torsion spring so that the test conductive spring 9 is in contact with the brass tube to form a certain pressure, 20 ensuring that the test circuit is conducted. The brass tube covers a cylinder, which is convenient for the brass tube to weld conductors, forming a loop of the test circuit (not shown). The test and reset button 1 is provided with a spring groove 103 in the middle part, and a reset spring 104 is assembled in the spring groove 103. 25 The upper part of the electric leakage lock 4 is provided with an edge-protruding buckling part 401, the edge-protruding buckling part 401 is in a snap-in linkage with a buckling part 104 of the test and reset button 1, the middle part of the electric leakage lock is provided with a circular through-hole 402 into which a shaft 8 is inserted so that the electric leakage lock 4 can rotate around the shaft 8, and the lower part of the 30 electric leakage lock is provided with a circular protruding part 403 for beating a lock 5 catch. When an electric leakage occurs, the action of a release causes the electric leakage lock 4 to rotate clockwise, and the circular protruding part 403 in the lower part beats the lock catch 11 of the leakage circuit breaker so that the lock catch 11 is separate from a jump button for disconnecting and protecting the electric leakage; 5 meanwhile, the edge-protruding buckling part 401 in the upper part of the electric leakage lock 4 is detached from the buckling part 104 in the bottom of the test and reset button 1, forcing the circular protruding part 403 in the lower part of the electric leakage lock 4 to be pushing the lock catch 11 of the leakage circuit breaker to turn on the jump button of the leakage circuit breaker all the time and also enabling the switch 10 to be in an off-state which cannot be turned on all the time. The switch can work normally only by pressing the test and reset button 1 so as to remove the effect of the electric leakage lock. The lower part of the handle 3 is provided with an arc protruding part 301, the protruding part 301 of the handle forces the test conductive spring 9 to be in contact 15 with the brass tube A5 when the leakage circuit breaker is in a state of switching on, and the contact keeps switched off when the leakage circuit breaker is in a state of switching off. The test circuit occurring in the leakage simulation has a function of disconnecting and protecting dual-breakpoint, the test and reset button 1 drives the 20 test conductive spring 9 to be in contact with the brass tube A5 in the leakage test circuit so as to form a breakpoint, and the other breakpoint is formed in such a way that the protruding part 301 of the handle forces the test conductive spring 9 to be in contact with the brass tube B7 in the power supply line of the electronic circuit board. Simulating electric leakage experiment: when the handle 3 of the leakage circuit 25 breaker is in an on-state, namely, in a power-up state, the test and reset button 1 moves downward when the test and reset button 1 is pressed (being equivalent to the simulating electric leakage). The bottom end of the test and reset button compresses the test conductive spring 9, forcing the test conductive spring 9 to be in conductive contact with the brass tube A5. The simulating electric leakage current flows through 30 the test circuit (the circuit drawing not being shown). After the leakage signal is 6 processed by the circuit board, the current is output to the electric leakage release 12. The action of the electric leakage release 12 pushes the push rod 10 to act on the electric leakage lock 4, and then the electric leakage lock 4 rotates around the shaft 8. The circular protruding part 403 of the electric leakage lock 4 beats the lock catch 11 5 so that the lock catch 11 is separate from the jump button and the moving and fixed contacts are switched off in order to achieve the effect of protection. When the electric leakage lock 4 rotates around the shaft 8, the edge-protruding buckling part 401 of the electric leakage lock is separate from the snap-in part 104 of the test and reset button. The test and reset button 1 moves upward due to the effect of the test and reset spring 10 2. The R-layer surface part 102 of the test and reset button is higher than the frame body, being equivalent to the kinetic energy with the indication of the electric leakage status. When the test and reset button 1 is in the electric leakage indication status, the handle 3 cannot be turned off when it is switched on. The test and reset button 1 is pressed only after releasing the leakage fault so that the R-layer surface part 102 of 15 the test and reset button is parallel to the frame body after the snap-in part 104 of the test and reset button is buckled with the edge-protruding buckling part 401 of the electric leakage lock 4, which is the leakage reset function of the test and reset button. 7
