In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 3, the present embodiment provides an anti-misoperation mechanism, which includes a locking member 20 disposed in a housing 200 of a switch device, wherein a limiting end of the locking member 20 passes through a limiting hole 210 on the housing and extends out of the housing 200; the switch device is driven to move towards the inside of the mounting carrier 400, and the limit end extending out of the housing 200 can be pushed to retract into the housing 200, so that the buckle 20 locks the closing operation of the operating handle 300 of the switch device.

Thus, when the switching device is mounted, if the operating handle 300 is located at the opening position at this time, when the switching device is pushed into the mounting carrier 400, the inner wall surface of the mounting carrier 400 acts on the latch 20, the latch 20 is forced to retract, and the closing movement of the operating handle 300 is locked to limit the closing movement of the operating handle 300; when the switch device is mounted, if the operating handle 300 is in the closing position, the inner wall of the mounting carrier 400 acts on the latch 20, and the operating handle 300 is located below the latch 20, so that the latch 20 is restricted from retracting (see fig. 5 and 6), and thus the switch device cannot be mounted on the mounting carrier 400 in the closing state. Therefore, the misoperation prevention mechanism provided by the embodiment can avoid the situation that a switching device is switched on in the installation process and is installed in the installation carrier 400 in the switching-on state, and further can improve the safety of the circuit breaker in the installation process.

It should be noted that, in order to enable the switch device to enable the latch 20 to extend out of the housing 200 through the limiting hole 210 in the initial state, and to retract into the housing 200 from the limiting hole 210 after the latch 20 is pressed, in this embodiment, the latch 20 may be made of an elastic material. For example, it may be a spring plate with a certain thickness.

Of course, the anti-misoperation mechanism provided in this embodiment may further include a separate elastic member (not shown) in addition to the buckle 20 itself being made of an elastic material. That is, the anti-misoperation mechanism provided in this embodiment further includes an elastic member, one end of the elastic member is connected to the locking member 20, and the other end of the elastic member is used for being connected to the housing 200, and the locking member 20 can extend out of the housing 200 through the limiting hole 210 on the housing 200 under the elastic force of the elastic member.

In this embodiment, one end of the elastic member is used to connect with the housing 200 of the switch device, and the other end of the elastic member is connected with the latch 20, so as to provide an acting force for the latch 20 to move towards the limiting hole 210 of the housing 200 of the switch device. Thus, in the state that the elastic member is not stressed, the latch member 20 can extend out of the limiting hole 210 of the housing 200, thereby preventing the latch member 20 from affecting the normal opening and closing of the operating handle 300 of the switch device.

Both ends of the elastic member may be respectively abutted against the housing 200 and the latch 20; one end of the elastic element can abut against the fastener 20 or the shell 200, and the other end of the elastic element is connected with the shell 200 or the fastener 20; of course, the locking mechanism may be fixedly connected to the locking member 20 and the housing 200, respectively. Specifically, the connection manner of the elastic element is not limited in this embodiment, as long as the elastic element can drive the fastening element 20 to extend out through the limiting hole 210 of the housing 200 in the initial state (i.e., in the unstressed state), and the fastening element 20 can be driven to retract into the housing 200 to abut against the operating handle 300 in the stressed state, so as to limit the movement of the operating handle 300.

In this embodiment, the locking member 20 passes through the limiting hole 210 and extends out of the housing 200 under the elastic force of the elastic member. For example, the latch 20 may be integrally protruded out of the housing 200 under the elastic action of the elastic member, or may be partially protruded out of the housing. It should be noted that the latch 20, whether it extends entirely out of the housing 200 or partially out of the housing 200, should be such that the latch 20 does not interfere with the movement of the operating handle 300.

Referring to fig. 1 to 3, when the switch device needs to be installed, the switch device is pushed to move toward the inside of the body, and at this time, the locking member 20 is driven to retract under the action of the inner wall surface of the installation carrier 400, and further retracts into the housing 200, and then abuts against the operating handle 300 in the housing 200, so that the operating handle 300 cannot perform a closing operation, and thus, the switch device can be prevented from being closed due to misoperation in the process of installing the switch device.

Alternatively, in the present embodiment, when the switching device is driven to move toward the inside of the mount carrier 400, the catch 20 can be driven to retract and lock the operation handle 300. Here, the locking of the operating handle 300 is a locking of a closing operation of the operating mechanism, please refer to fig. 2 to 6, in this orientation, the locking member 20 is retracted to lock a rightward movement of the operating mechanism, where the rightward movement of the operating mechanism is a closing operation, and the leftward movement of the operating mechanism is an opening operation.

Optionally, in order to further improve the safety of the switch device installation process, in the present embodiment, when the operating handle 300 is in the switching-on position, the operating handle 300 is located below the latch 20 for limiting the retraction of the latch 20 into the housing 200, please refer to fig. 5.

Thus, when the switching device is driven to move towards the inside of the mounting carrier 400, if the operating handle 300 is located at the opening position at this time, referring to fig. 2 and fig. 3, at this time, when the switching device is pushed into the mounting carrier 400, the inner wall surface of the mounting carrier 400 acts on the fastener 20, the fastener 20 retracts under the force and is further abutted against the operating handle 300, so that the operating handle 300 is limited from moving rightwards to be closed; when the switch device is driven to move towards the inside of the mounting carrier 400, if the operating handle 300 is at the closing position, referring to fig. 5, the operating handle 300 abuts against the locking member 20, the locking member 20 cannot be retracted, and at this time, the switch device cannot be mounted. In this case, the operating handle 300 may be returned to the open position before the switching device is mounted.

Optionally, in this embodiment, after the switch device is mounted in place, the fastener 20 of the anti-misoperation mechanism may extend through the clearance hole 410 of the mounting carrier 400, so as to unlock the operating handle 300, so that the operating handle 300 can perform normal opening and closing operations. Referring to fig. 1, in the installation process, the latch 20 of the switch device is always in the retracted state due to the inner wall of the installation carrier 400, at this time, the operating handle 300 is locked and cannot be switched on, after the switch device is installed in place, the latch 20 reaches the position-avoiding hole 410 of the installation carrier 400, at this time, the acting force of the installation carrier 400 is lost, and at this time, the latch 20 can sequentially pass through the limiting hole 210 and the position-avoiding hole 410 under the elastic force of the elastic member to extend and reset, so as to unlock the operating handle 300.

Referring to fig. 4, fig. 6 and fig. 7, optionally, the locking member 20 includes a first body 21 and a protrusion 22 connected to the first body 21 (the protrusion 22 is the above-mentioned limit end that can extend out of the housing 200 in the initial state and can retract into the housing 200 in the compressed state), and the protrusion 22 can extend out of the housing 200 under the elastic force of the elastic member. That is, the latch 20 may cause the protrusion 22 to protrude out of the housing 200 and lock the closing operation of the operating handle 300 by the first body 21 during the installation of the switching device.

In order to save labor and facilitate installation of the switch device, in the present embodiment, optionally, a side of the protrusion 22 away from the first body 21 is provided with an inclined surface 221, and an included angle α between the inclined surface and the first body is an obtuse angle. Thus, when the switching device is moved toward the inside of the mount carrier 400, the inner wall surface of the mount carrier 400 can act on the inclined surface 221 of the projection 22, and thus the switching device can be mounted quickly.

It should be noted that, in the present embodiment, the inclined surface 221 faces away from the operation end of the operation handle 300, in other words, an included angle α between the inclined surface and the first body is an obtuse angle, as shown in fig. 6. Specifically, the specific angle of the obtuse angle is not limited in this application, and can be set reasonably by those skilled in the art according to actual conditions.

For example, the inclined surface 221 may be a plane or an arc surface.

In addition, in the present embodiment, referring to fig. 3 to fig. 6, when the locking element 20 retracts into the housing 200, one end of the first body 21 can abut against the limiting groove 310 of the operating handle 300 to lock the operating handle 300. Thus, the movement of the operating handle 300 is restricted by the latch 20, and the closing operation cannot be performed. In addition, if the operating handle 300 is in the on position before the attachment, the latch 20 cannot be retracted due to the restriction of the operating handle 300, and the attachment cannot be performed.

Alternatively, the end of the latch 20 away from the operating handle 300 is used for hinging with the housing 200, and the end close to the operating handle 300 is connected with the elastic member. In this way, the snap member 20 can be easily ejected from the housing 200 and retracted into the housing 200. Of course, in other embodiments, the skilled person can also use other ways to realize the ejection and retraction of the latch 20, such as fixedly connecting the latch 20 with the elastic member, and abutting or fixing the elastic member on the housing 200.

In this embodiment, optionally, the elastic member is a torsion spring, and the torsion spring is configured to be sleeved on the positioning column 220 of the housing 200. Thus, one end of the torsion spring can abut against the latch 20, the other end can abut against or be fixed to the housing 200, and the torsion spring can provide an acting force for the latch 20 to move towards the limiting hole 210. Thus, in the initial state (i.e., when the torsion spring is not storing energy), the locking member 20 extends through the limiting hole 210; when the inner wall of the mounting carrier 400 acts on the fastener 20, the fastener 20 retracts to drive the torsion spring to store energy; when the switching device is mounted in place, the locking member 20 extends through the limiting hole 210 under the action of the energy released by the torsion spring.

To facilitate the removal of the switching device, the anti-misoperation mechanism optionally further comprises an unlocking member 30 disposed on the housing 200, the unlocking member 30 being rotatable relative to the housing 200; the operating handle 300 is driven to move away from the latch 20, and the unlocking member 30 is driven by the operating handle 300 to rotate, and drives the latch 20 to retract into the housing 200. Thus, when it is desired to remove the switching device from the mounting carrier 400, the operating handle 300 can be driven to move to the left (see fig. 2 and 4), and at this time, the operating handle 300 can act on the unlocking member 30 to drive the unlocking member 30 to rotate, and the rotation of the unlocking member 30 can drive the fastener 20 to retract into the housing 200. At this time, the switching device may be pulled out from the mounting carrier 400.

Illustratively, when the switch device needs to be removed from the mounting carrier 400, the operating handle 300 may be pulled leftward (i.e., the operating handle 300 is driven to move toward the open position), at this time, the operating handle 300 will act on the unlocking member 30, so as to drive the unlocking member 30 to rotate clockwise, so as to enable the unlocking member 30 to act on the latch member 20 to drive the latch member 20 to rotate counterclockwise, so that one end of the latch member 20 close to the unlocking member 30 will move downward, so that the latch member 20 will drive the limiting end (i.e., the protrusion 22) to retract into the housing 200, so that a worker can pull the switch device out of the mounting carrier 400 as a whole, and then detach the switch device from the mounting carrier 400.

Illustratively, referring to fig. 4 and 8 in combination, the unlocking member 30 includes a second body 31, and a first driving rod 32 and a second driving rod 33 respectively connected to two opposite sides of the second body 31, wherein the second body 31 is rotatably connected to the housing 200, the first driving rod 32 is configured to be in transmission connection with the operating handle 300, and the second driving rod 33 is configured to drive the fastener 20 to retract into the housing 200. As a result, the operating handle 300 is driven to move to the left, and at this time, the operating handle 300 acts on the first driving lever 32 of the unlocking member 30, thereby driving the second body 31 to rotate on the housing 200, and the second driving lever 33 of the unlocking member 30 rotates and acts on the buckle 20, so as to press the buckle 20 and retract the buckle 20 into the housing 200.

Referring to fig. 7, optionally, an accommodating groove 23 is disposed at an end of the locking member 20 close to the second driving rod 33, and the accommodating groove 23 is used for accommodating at least a portion of the second driving rod 33. Thus, when the second driving rod 33 acts on the fastener 20, the second driving rod 33 can be accommodated in the accommodating groove 23, so that the second driving rod 33 and the fastener 20 can be prevented from slipping, and the operational reliability of the unlocking piece 30 driving the fastener 20 to rotate can be improved.

Of course, the accommodating groove 23 may accommodate the entire second driving rod 33 or a part of the second driving rod 33.

The utility model discloses an on the other hand provides a switching device, and this switching device includes foretell mistake operating device that prevents. Since the structure of the anti-misoperation mechanism and the beneficial effects thereof have been described in detail in the foregoing, they are not described in detail herein.

The above description is only an alternative embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and in order to avoid unnecessary repetition, the present invention does not need to describe any combination of the features.
