[0045] Based on the problems in the prior art, please refer to Figures 1 to 15 The utility model embodiment provides an operating device 10, which is applied to the technical field of electrical equipment, and can be particularly applicable to a circuit breaker. The operating device 10 provided by the embodiment has a relatively simple structure, small rotational inertia, and can realize rapid tripping, so that the moving contact 310 and the stationary contact 320 are timely opened, and the safety performance is improved.

[0046] In detail, the operating device 10 comprises a mounting shell 100, a mounting assembly 200, a contact assembly 300, a driving assembly 400 and a tripping mechanism 500.

[0047] The mounting assembly 200 comprises a mounting seat 210, a jump buckle 220 and an elastic piece 230, the contact assembly 300 comprises a moving contact 310, a stationary contact 320 and a moving contact reset piece 330, the driving assembly 400 comprises a handle 410 and a connecting rod 420, and the tripping mechanism 500 comprises a lock buckle 510 and a driving piece 520.

[0048] The mounting seat 210, the movable contact 310, the static contact 320, the movable contact reset member 330 and the jump buckle 220 are all mounted in the mounting shell 100. The mounting seat 210 and the movable contact 310 are rotatably arranged in the mounting shell 100; the static contact 320 is arranged in the mounting shell 100; the movable contact reset member 330 is arranged in the mounting shell 100 and connected with the movable contact 310, and the movable contact reset member 330 is used for enabling the movable contact 310 to have a tendency to move away from the static contact 320; and the jump buckle 220 is movably arranged in the mounting seat 210.

[0049] The jump buckle 220 abuts against the movable contact 310, so that the mounting seat 210 can drive the jump buckle 220 to rotate under the driving of the handle 410, so as to drive the movable contact 310 to close or open the static contact 320; or, the jump buckle 220 is used for being separated from the movable contact 310, so that in the case that the movable contact 310 is closed with the static contact 320, the movable contact 310 is separated from the static contact 320 under the driving of the movable contact reset member 330.

[0050] In the embodiment, the movable contact 310 is rotatably arranged in the mounting shell 100, so that the movable contact 310 can be rotated to contact the static contact 320, that is, the movable contact 310 and the static contact 320 are in a closed state (as shown in FIG. 2a); of course, the movable contact 310 can also be rotated to be separated from the static contact 320, that is, the movable contact 310 and the static contact 320 are in an open state (as shown in FIG. 2b). Figure 3 Figure 4

[0051] In the normal operation of the operating device 10, the jump buckle 220 is arranged in the mounting seat 210 and abuts against the movable contact 310, so that the mounting seat 210 can drive the jump buckle 220 to rotate under the driving of the handle 410, and finally the jump buckle 220 drives the movable contact 310 to rotate, so as to realize the closing or opening of the movable contact 310 and the static contact 320.

[0052] In the case that the movable contact 310 is closed with the static contact 320 and in the case that the operating mechanism or circuit is in a fault condition, since the jump buckle 220 is movably arranged in the mounting seat 210, the jump buckle 220 can be rotated relative to the mounting seat 210 to be separated from the movable contact 310, so that the movable contact 310 is no longer limited by the jump buckle 220 and the mounting seat 210, and at this time, the movable contact 310 can be reset to the open state with the static contact 320 under the driving of the movable contact reset member 330.

[0053] Therefore, through the above design, after the movable contact 310 is separated from the limitation of the jump buckle 220, only the movable contact 310 is rotated under the driving of the movable contact reset member 330 and separated from the static contact 320, the rotational inertia is small and the tripping speed is fast, so as to realize the quick opening of the movable contact 310 and the static contact 320 and improve the safety performance of the operating device 10. ​​

[0054] Further, as shown in Figure 2 The side wall of the moving contact 310 is concavely provided with a first abutting part 311, and the end of the jump lever 220 is convexly provided with a second abutting part 221, which is in clamping cooperation with the first abutting part 311.

[0055] In the embodiment, the first abutting part 311 and the second abutting part 221 are in clamping cooperation, so that the jump lever 220 can stably abut against the moving contact 310.

[0056] Further, the mounting shell 100 is provided with a main shaft 110, and the mounting seat 210 and the moving contact 310 are rotatably arranged on the main shaft 110. The handle 410, the connecting rod 420 and the mounting seat 210 are sequentially connected in transmission and jointly form a transmission four-link mechanism, i.e., a four-link mechanism 420 structure shown by the dotted line. Figure 3 and Figure 4 The transmission four-link mechanism is not damaged when the operating device is tripped and opened.

[0057] Since the four-link mechanism 420 structure in the existing circuit breaker is composed of the handle, the connecting rod 420, the mounting seat 210 and the jump lever 220, the stability of the four-link mechanism 420 structure will be affected when the jump lever 220 is tripped. Therefore, in the embodiment, one end of the jump lever 220 is movably arranged on the mounting seat 210, and the other end is used for abutting against or separating from the moving contact 310. After a fault occurs and the jump lever 220 separates from the moving contact 310, the jump lever 220 rotates with the mounting seat 210 and does not damage the four-link mechanism 420 structure formed by the handle 410, the connecting rod 420 and the mounting seat 210, thereby ensuring that the jump lever 220 can be quickly tripped and effectively protecting the structural stability of the transmission four-link mechanism formed by the handle 410, the connecting rod 420 and the mounting seat 210.

[0058] In detail, the movement direction of the jump lever 220 is arranged at an angle with the rotation plane of the moving contact 310.

[0059] In the embodiment, the jump lever 220 moves along a direction perpendicular to the rotation plane of the moving contact 310, so that the movement path of the jump lever 220 does not interfere with the movement path of the transmission four-link mechanism formed by the handle 410, the connecting rod 420 and the mounting seat 210 in sequence, thereby realizing that the jump lever 220 does not damage the four-link mechanism 420 structure formed by the handle 410, the connecting rod 420 and the mounting seat 210 after being tripped.

[0060] In detail, the mounting shell 100 is provided with a third cooperation part 120, the mounting seat 210 is provided with a fourth cooperation part 211, and the moving contact reset member 330 is a torsion spring structure, one end of which abuts against the third cooperation part 120, and the other end abuts against the fourth cooperation part 211.

[0061] In the embodiment, the movable contact reset member 330 is arranged on the main shaft 110, and one end of the movable contact reset member 330 is in abutment with the third matching part 120, and the other end is in abutment with the fourth matching part 211, and the movable contact reset member 330 is in a compressed state in this state, so that after the movable contact 310 is out of the abutment limiting action of the jump buckle 220, the movable contact 310 can rotate in the direction of moving away from the static contact 320 under the elastic restoring force of the movable contact reset member 330, that is, it is restored to the open state.

[0062] Further, the mounting shell 100 is also provided with a limiting shaft 130, which is used to abut with the movable contact 310 under the action of the movable contact reset member 330.

[0063] In the embodiment, since the movable contact 310 and the static contact 320 are separated by a certain distance after being separated, after the movable contact 310 is rotated away from the static contact 320 by the movable contact reset member 330, the movement of the movable contact 310 is limited by the limiting shaft 130, so as to achieve the open limiting.

[0064] Further, the driving member 520 is arranged on the mounting shell 100, and the lock buckle 510 is rotatably arranged on the main shaft 110, and the lock buckle 510 is in abutment with the jump buckle 220, and is used to limit the jump buckle 220, so that the jump buckle 220 and the movable contact 310 are kept in the abutment state; or the lock buckle 510 is used to rotate in the first direction (clockwise direction shown in the figure) under the driving of the driving member 520, so that the lock buckle 510 is separated from the jump buckle 220.

[0065] In the embodiment, under the normal operation of the operating mechanism, the lock buckle 510 is in abutment with the jump buckle 220, so that the jump buckle 220 is in abutment with the movable contact 310, so that the mounting seat 210 can drive the jump buckle 220 to rotate when the mounting seat 210 rotates, and the jump buckle 220 drives the movable contact 310 to rotate, so as to realize the normal closing or opening of the movable contact 310 and the static contact 320.

[0066] And in the case of failure, the trip mechanism 500 is started, that is, the top pin of the output end of the driving member 520 extends to abut the arc surface structure of the lock buckle 510, so that the lock buckle 510 rotates around the main shaft 110 in the first direction under the top holding action of the driving member 520, so that the trip is separated from the jump buckle 220, and after the jump buckle 220 is separated from the abutment limiting of the lock buckle 510, the movable contact reset member 330 drives the movable contact 310 to rotate in the first direction, and the movable contact 310 pushes the jump buckle 220 to rotate relative to the rotation plane until the jump buckle 220 is separated from the movable contact 310, and finally the movable contact 310 is separated from the static contact 320 under the driving of the movable contact reset member 330 and is in abutment with the limiting shaft 130.

[0067] Further, the tripping mechanism 500 further comprises a lock catch reset member 530, which is arranged on the mounting base 210 and connected with the lock catch 510, and is used to make the lock catch 510 have a tendency to rotate in the second direction (counterclockwise direction as shown in the figure) so as to make the lock catch 510 abut against the trip catch 220.

[0068] In the embodiment, the first direction and the second direction are opposite directions, that is, the first direction is the clockwise direction as shown in the figure, and the second direction is the counterclockwise direction as shown in the figure.

[0069] It should be noted that after the trip catch 220 is tripped by the driving of the driving member 520 and the movable contact 310 is tripped from the stationary contact 320 and abuts against the limiting shaft 130 under the driving of the movable contact reset member 330, the handle 410 is pulled back to the original position by the reset spring at this time, and the mounting base 210 is reset to the state at the time of tripping under the driving of the handle 410 and the connecting rod 420, and the lock catch 510 abuts against the movable contact 310 again; at this time, since the lock catch reset member 530 always has a force on the lock catch 510 in the second direction, the lock catch reset member 530 makes the lock catch 510 reset to the state of abutting against the trip catch 220 again under the action of the lock catch reset member 530, so that the mounting base 210 and the lock catch 510 are in a relatively stable mounting state.

[0070] In detail, the lock catch reset member 530 is a torsion spring structure, the mounting base 210 is provided with a first matching part 212, the lock catch 510 is provided with a second matching part 511, the lock catch reset member 530 is installed on the mounting shaft of the mounting base 210, and one end thereof abuts against the first matching part 212 and the other end thereof abuts against the second matching part 511.

[0071] In the embodiment, the lock catch reset member 530 is arranged on the mounting shaft of the mounting base 210, one end of the lock catch reset member 530 abuts against the first matching part 212, and the other end thereof abuts against the second matching part 511, and the lock catch reset member 530 in this state is in a compressed state, so that after the lock catch 510 is separated from the abutting action of the driving member 520, the elastic restoring force generated by the lock catch reset member 530 can be used to rotate in the second direction, so that the lock catch 510 abuts against the trip catch 220, and finally the trip catch 220 abuts against the movable contact 310.

[0072] Further, the movable contact 310 is provided with a let-in hole 312, the main shaft 110 passes through the let-in hole 312, the movable contact 310 can rotate relative to the main shaft 110, and the movable contact 310 can be displaced in the rotating plane.

[0073] In detail, the let-in hole 312 has a first end 3121 and a second end 3122;

[0074] Before closing begins, the handle 410 rotates the mounting base 210, which in turn rotates the trip latch 220 and the moving contact 310 until the moving contact 310 contacts the stationary contact 320; Figure 7 As shown, after the moving contact 310 and the stationary contact 320 just come into contact, that is, during the process when the handle 410 drives the moving contact 310 to close and is in an overtravel state, the handle 410 drives the mounting base 210 to rotate, and the mounting base 210 drives the trip latch 220 to move. Finally, the trip latch 220 drives the moving contact 310 to move along the extension direction of the relief hole 312, so that the main shaft 110 moves relative to the relief hole 312 from the first end 3121 to the second end 3122, as shown. Figure 8 As shown, at this time, the moving contact 310 and the stationary contact 320 are in the closed state and in the overtravel end state. Thus, the overtravel is completed through the clearance hole 312, reducing the movement space of the moving contact 310 and thus saving space.

[0075] It is understandable that when the handle 410 drives the moving contact 310 to open and is in an overtravel state, the moving contact 310 moves along the extension direction of the relief hole 312 so that the main shaft 110 moves from the second end 3122 to the first end 3121 relative to the relief hole 312.

[0076] Furthermore, such as Figures 9 to 14 As shown, the mounting base 210 has a snap-lock groove 213 and an elastic element groove 214 on its opposite side walls. At least a portion of the snap-lock 220 is embedded in the snap-lock groove 213, and at least another portion is located on one side of the elastic element groove 214. The elastic element 230 is disposed in the elastic element groove 214 and abuts against the snap-lock 220 to restrict the snap-lock 220 from moving away from the snap-lock groove 213 and to make the snap-lock 220 abut against the moving contact 310.

[0077] First, it should be noted that when the elastic element 230 is in a compressed state, the force exerted by the elastic element 230 on the jumper 220 is less than the force exerted by the moving contact reset element 330 on the moving contact 310. Therefore, when the jumper 220 disengages from the moving contact 310, the moving contact 310 can push the jumper 220 under the action of the moving contact reset element 330, causing the elastic element 230 to be further compressed under the action of the jumper 220 until the jumper 220 is completely disengaged from the moving contact 310.

[0078] In the embodiment, the elastic member slot 214 and the jump ring slot 213 are arranged on the two side walls of the mounting base 210 respectively, and at least part of the jump ring 220 is embedded in the jump ring slot 213 and at least another part is located on one side of the elastic member slot 214, so that when the elastic member 230 is arranged in the elastic member slot 214 and abuts against the jump ring 220, the jump ring 220 can be firmly mounted in the jump ring slot 213 of the mounting base 210, the jump ring 220 and the mounting base 210 are self-locked, and the jump ring 220 is pressed to stably abut against the movable contact 310.

[0079] Therefore, the structure is simple, convenient to assemble, and can effectively improve the production efficiency.

[0080] Further, as shown in Figure 15 and Figure 16 , the elastic member 230 includes a connecting portion 231, a first fixing portion 232, a second fixing portion 233 and a functional portion 234, the first fixing portion 232 and the second fixing portion 233 are connected with the connecting portion 231 and arranged at an included angle, and the first fixing portion 232 and the second fixing portion 233 abut against the two side walls of the elastic member slot 214 respectively, so that the elastic member 230 is in a compressed state.
