DETAILED DESCRIPTION

[0029] The embodiment of the utility model's controller's reset button module of electric energy meter external circuit breaker, as shown in Figures 1-8 It is shown that including shell 1, swing piece 2 arranged in shell 1, leakage protection tripping mechanism 3, swing piece 2 and shell 1 swingably connected, leakage protection tripping mechanism 3 can drive swing piece 2 swing, swing piece 2 one end is provided with transmission part 21, shell 1 is provided with the through hole 11 for transmission part 21 movable and is arranged in the outside of shell 1, shell 1 is provided with reset button 4, for driving reset button 4 to the reset spring that pops out the outside of shell 1, the reset spring is arranged between shell 1 and reset button 4, shell 1 swingably be provided with transmission piece 5, transmission piece 5 includes first, second, third swing end, transmission piece 5's first swing end 51 and leakage protection tripping mechanism 3's top rod 31 are connected, and leakage protection tripping mechanism 3 can drive transmission piece 5 whole rotation through first swing end 51.

[0030] like Figure 1 As shown, in use, the housing 1 and the circuit breaker 8 are connected together, and the transmission part 21 is connected to the operating mechanism of the adjacent circuit breaker 8, for example, connected to the latch of the operating mechanism. The transmission part 21 can drive the connected circuit breaker 8 to trip, and at the same time can restrict the closing action of the circuit breaker 8 (by restricting the latch of the operating mechanism to lock).

[0031] The second swing end 52 of the transmission component 5 forms a locking or unlocking engagement with the reset button 4 through swinging. In normal operation, the second swing end 52 locks the reset button 4, keeping it in the pressed state. The third swing end 53 does not restrict the movement of the transmission part 21 between the closed position and the tripped position, and the circuit breaker can open and close normally.

[0032] When leakage occurs, the leakage protection tripping mechanism 3 drives the transmission component 5 to rotate, and the second swing end 52 unlocks the reset button 4. The reset button 4 pops out under the action of the reset spring, which can provide a fault warning to the staff. At the same time, the third swing end 53 pushes the transmission part 21 to move towards the trip position, thereby controlling the circuit breaker connected to the transmission part 21 to trip.

[0033] When the reset button 4 is in the pop-out state, it forms a limiting engagement with the second swing end 52, and the third swing end 53 restricts the transmission part 21 at one end of the swing member 2 from swinging in the closing direction. At this time, even if the leakage protection trip mechanism 3 is reset, the transmission member 5 cannot reset its swing because the second swing end 52 of the transmission member 5 is restricted. The third swing end 53 restricts the closing movement of the transmission part 21, and the circuit breaker cannot close normally. Only when the operator manually presses the reset button 4 can the second swing end 52 be locked with the reset button 4 again under the action of the spring in the leakage protection trip mechanism 3, so that the transmission member 5 can reset its swing to the normal working position.

[0034] The leakage protection tripping mechanism 3 includes a push rod 31, the front end of the push rod 31 includes an annular groove 311, the first swing end 51 of the transmission component 5 is a plate-shaped structure, and includes a large hole 511, a small hole 512, and a connecting groove 513 connecting the small hole 512 and the large hole 511. The large hole 511 is located close to the axis of the transmission component 5 relative to the small hole 512. The diameter of the push rod 31 is smaller than the diameter of the large hole 511 and larger than the diameter of the small hole 512. The annular groove 311 of the push rod 31 is positioned in conjunction with the inner edge of the small hole 512.

[0035] When assembled, the front end of the ejector rod 31 is first inserted into the large hole 511, and then passes through the connecting slot 513 to the small hole 512, the connecting structure is simple and convenient to assemble, it should be noted that after assembly, there is a certain activity space between the ejector rod 31 and the first swing end 51, so that the front end of the ejector rod 31 and the first swing end 51 can swing within a certain angle range.

[0036] The second swing end 52 of the transmission member 5 is a plate-shaped structure, one side of the second swing end 52 is provided with a first notch 521, and one end of the second swing end 52 is formed with a first protrusion 522 in front of the first notch 521, and the corresponding side of the reset button 4 is provided with a second notch 41 for lateral embedding of the first protrusion 522, and the lower end of the reset button 4 is provided with a second protrusion 42 which can be embedded into the first notch 521.

[0037] When the reset button 4 is in the pop-up state, the first protrusion 522 cannot be embedded into the second notch 41, and the second protrusion 42 cannot be embedded into the first notch 521, so the reset button 4 will limit the swing range of the second swing end 52. When the first protrusion 522 is embedded into the second notch 41 and the second protrusion 42 is embedded into the first notch 521, the second swing end 52 will lock the reset button 4, so that the reset button 4 cannot be popped up under the action of the reset spring.

[0038] The transmission member 5 includes a first shaft hole 50, and the swing member 2 includes a second shaft hole 20, the first shaft hole 50 and the second shaft hole 20 are rotationally connected with the connecting shaft which is inserted or integrally formed on the shell 1, so as to facilitate the connection between the transmission member 5, the swing member 2 and the shell 1.

[0039] The first swing end 51 and the second swing end 52 of the transmission member 5, the leakage protection tripping mechanism 3 and the reset button 4 are correspondingly distributed at the first axial position of the transmission member 5, and the third swing end 53 of the transmission member 5 is correspondingly distributed at the second axial position of the transmission member 5, the second axial position of the transmission member 5 is closer to the inner wall of the shell 1 with the through hole 11 than the first axial position, so that the leakage protection tripping mechanism 3, the reset button 4, the swing member 2 and the transmission member 5 do not interfere with each other, and the structure is more compact.

[0040] As shown in Figure 2 The inner cavity of the shell 1 includes a relatively narrow upper cavity 101 and a relatively wide lower cavity 102, both sides of the junction between the upper cavity 101 and the lower cavity 102 have L-shaped side walls 12, the reset button 4 is arranged in the upper cavity 101, the leakage protection tripping mechanism 3 is horizontally arranged at the upper part of the lower cavity 102 and below one of the L-shaped side walls 12, and the transmission member 5 is arranged at the junction between the upper cavity 101 and the lower cavity 102, the structure is compact and occupies a small space inside the shell 1.

[0041] The other end of the swing member 2 has a pushing part 22 which is in pushing cooperation with a movable element in the housing 1, and the movable element can push the transmission part 21 at one end of the swing member 2 to move by pushing the pushing part 22, so that the swing member 2 is not limited to the leakage protection function.

[0042] The movable element is an electric actuator 6, and the pushing part 22 is in linkage cooperation with the electric actuator 6 of the controller, and the electric actuator 6 can drive the transmission part 21 at one end of the swing member 2 to move in the tripping direction and limit the transmission part 21 at one end of the swing member 2 to move in the closing reset direction, for example, the circuit breaker can be remotely controlled to trip, and the re-closing of the circuit breaker is limited.

[0043] The electric actuator 6 drives and limits the swing of the transmission part 5 by the cam mechanism 7 which is in abutting limiting cooperation with the other end of the transmission part 5, and when the cam of the cam mechanism 7 rotates, the transmission part 5 can be pushed to swing and can also limit the swing of the transmission part 5.
