Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to an electrical signal device and a circuit breaker. Background Art

[0002] like Figure 1 As shown, the drawer-type frame circuit breaker includes a drawer seat 1', a three-position electrical signal device, and a circuit breaker body that cooperates with swinging in or out in the drawer seat 1'. The drawer seat 1' and the circuit breaker body cooperate with three working positions of "connection position", "test position" and "separation position". The function of the three-position electrical signal device is to output and transmit the three positions of the circuit breaker body when swinging in and out, the separation position, the test position and the connection position to the user end in the form of electrical signals, so that the user end can monitor the real-time position status of the circuit breaker body in the drawer seat 1', so as to improve the safety and reliability of the circuit breaker body during operation inspection.

[0003] like Figures 2 to 5 As shown, the three-position electrical signal device includes a micro-motion component 21', a trigger 22', a terminal 23' and a connecting wire; wherein the micro-motion component 21' and the trigger 22' are respectively mounted on the bottom plate of the drawer seat 1', the terminal 23' is mounted on the side plate of the drawer seat 1', and the electrical signal of the micro-motion component 21' is transmitted to the terminal 23' through the connecting wire; the micro-motion component 21' includes a mounting bracket 211' and three micro-switches 212', the three micro-switches 212' are mounted on the mounting bracket 211' at different positions, and the micro-switch 212' is fixed to the bottom plate of the drawer seat 1' by the mounting bracket 211'; one end of the trigger 22' is mounted on the slide 24' in the drawer seat 1', and the other end of the trigger 22' is an arc slope structure 221' and can cooperate and abut with the micro-sensor 2121' of the micro-switch 212'.

[0004] When the circuit breaker body is rocked in or out of the drawer seat 1', the lead screw in the drawer seat 1' can respectively drive the circuit breaker body and the slide plate 24' to move along the X' axis, so that the slide plate 24' drives the trigger member 22' to move along the X' axis, so that the arc slope structure 221' on the trigger member 22' presses the micro-sensor 2121' of the micro-switch 212' during the movement; when the slide plate 24' moves to different positions along the X' axis, the trigger member 22' can trigger the three micro-switches 212' in sequence and transmit the electrical signal to the wiring terminal 23', and the user end can obtain the specific position signal of the circuit breaker body in the drawer seat 1' through the wiring terminal 23'.

[0005] However, the following problems are prone to occur due to the use of the above-mentioned three-position electrical signal device: 1. The three-position electrical signal device is installed on the bottom plate of the drawer seat 1'. The circuit breaker body needs to be moved out before installation, and the installation position is inconvenient; and the slide plate 24' will occupy the installation space in the drawer seat 1'; 2. The setting positions of the wiring terminals 23' and the micro-motion components 21' and the triggering members 22' are relatively scattered and far apart, and wires need to be connected in the middle for complex wiring connections; and multiple screws are required to position and fix each scattered part separately, resulting in the installation of the entire three-position electrical signal device on the drawer seat 1' being relatively complicated.

[0071] Embodiment 1

[0072] In this embodiment, an electrical signal device is proposed, such as Figures 6 to 9As shown, the electrical signal device includes a trigger beam 10 and a signal module 20; wherein the trigger beam 10 extends along the Y axis and is installed on the drawer seat 30, and a trigger member 11 is connected to the trigger beam 10; the signal module 20 includes a frame 21, wiring terminals 22 and three micro switches 23 respectively arranged in the frame 21, the three micro switches 23 are arranged at different positions in the frame 21, the frame 21 is arranged outside the side plate 31 of the drawer seat 30, the wiring terminals 22 are connected to the micro switches 23 for signal reception and conversion, and the wiring terminals 22 are used to transmit the electrical signal converted by the micro switches 23 to the user end for use; the trigger beam 10 can be driven by the circuit breaker body when it is shaken into or out of the drawer seat 30 and moves along the Z axis and the X axis respectively relative to the drawer seat 30, so that the trigger member 11 can trigger the micro switches 23 at different positions. The swinging in or out of the circuit breaker body in the drawer seat 30 is a common operation process in the existing drawer-type frame circuit breaker, and the specific swinging in or out principle will not be described here.

[0073] By connecting the trigger member 11 to the trigger beam 10, the wiring terminal 22 of the signal module 20 is connected to the micro switch 23 signal. When the circuit breaker body is shaken into or out of the drawer seat 30, the trigger beam 10 can be driven to move along the Z axis or X axis relative to the drawer seat 30, so as to drive the trigger member 11 on the trigger beam 10 to trigger the three micro switches 23 located at different positions, so as to obtain different working positions of the circuit breaker body in the drawer seat 30 according to the micro switches 23 at different positions, and the wiring terminal 22 transmits the obtained specific position signal of the circuit breaker body in the drawer seat 30 to the user end. The wiring terminal 22 and the micro switch 23 in this embodiment are respectively common structures in existing drawer-type frame circuit breakers.

[0074] Compared with the prior art, the electrical signal device in this embodiment changes the installation position and structural layout of the electrical signal device; by setting the trigger beam 10 for triggering the micro switch 23 on the drawer seat 30, the trigger beam 10 does not occupy the installation space in the drawer seat 30; and the signal module 20 is installed as a whole outside the side plate 31 of the drawer seat 30, which can make the installation of the signal module 20 simpler and more convenient than installing it on the bottom plate of the drawer seat 30, and there is no need to remove the circuit breaker body from the drawer seat 30 before installation; and the wiring terminals 22 of the signal module 20 and the micro switch 23 are integrated in a frame 21 with a close spacing, so there is no need to connect wires in the middle for complex wiring connection, and there is no need to use multiple screws to position and fix each part separately, so that the installation of the signal module 20 is simpler.

[0075] In the current electrical signal device, there are many transmission parts such as screws, slides and gears in the drawer seat 30, and the processing errors and installation errors of the parts will cause the errors to accumulate on the trigger beam 10, resulting in deviations in the moving position of the trigger beam 10 on the X-axis and the Z-axis, resulting in the trigger member 11 on the trigger beam 10 being unable to accurately trigger the three micro switches 23 in different positions.

[0076] In order to solve the above problems, in this embodiment, the trigger member 11 is made of elastic material so that the trigger member 11 has elastic buffering. Even if the processing error and installation error of the parts cause the error to accumulate on the trigger beam 10, the elastic buffering margin of the trigger member 11 itself can ensure the accurate movement position of the trigger member 11, so that the trigger member 11 can accurately contact the micro switch 23 at different positions, and there is no need to perform separate debugging before installing the micro switch 23, which saves time and effort, has high work efficiency, and can ensure the accuracy of the trigger position of the micro switch 23 by the trigger member 11; and, due to the elastic buffering effect of the trigger member 11, the trigger member 11 will not directly and rigidly contact the micro switch 23, so as to better protect the micro switch 23 and prevent the entire signal module 20 from falling from the side plate 31 of the frame 21. Among them, the trigger member 11 is specifically a spring sheet.

[0077] It is worth noting that in order to better reduce the accumulation of errors on the trigger beam 10 caused by the processing errors and installation errors of the transmission parts in the drawer seat 30, a displacement margin is set for the trigger beam 10. When the trigger beam 10 moves upward along the Z axis to the separation position, the trigger beam 10 can also move upward along the Z axis by a certain space margin, thereby compensating for the deviation of the trigger beam 10 at the separation position.

[0078] Furthermore, if Figure 7 and Figure 8 As shown, since the circuit breaker body has three working positions, namely, the connection position, the test position, and the separation position, correspondingly, the three micro switches 23 are respectively a connection switch 231, a test switch 232, and a separation switch 233, and the connection switch 231, the test switch 232, and the separation switch 233 are arranged in a triangle shape in the frame 21. Among them, the separation position means that the main circuit and the auxiliary circuit between the circuit breaker body and the drawer seat 30 are completely disconnected, the test position means that the auxiliary circuit between the circuit breaker body and the drawer seat 30 is connected, and the connection position means that the main circuit between the circuit breaker body and the drawer seat 30 is connected.

[0079] Specifically, if Fig. 9As shown, the trigger member 11 has a connection position trigger surface 111, a test position trigger surface 112 and a separation position trigger surface 113 which are respectively located on the inner side, the lower side and the upper side; when the trigger member 11 moves inward along the X-axis, the connection position trigger surface 111 can trigger the connection switch 231, and the circuit breaker body is at the connection position; when the trigger member 11 moves downward along the Z-axis, the test position trigger surface 112 can trigger the test switch 232, and the circuit breaker body is at the test position; when the trigger member 11 moves upward along the Z-axis, the separation position trigger surface 113 can trigger the separation switch 233, and the circuit breaker body is at the separation position.

[0080] Specifically, Fig. 9 As shown, the trigger member 11 includes a first plate 116, a second plate 117, a V-shaped plate 118, a third plate 114 and a fourth plate 119 which are connected in sequence to form an unclosed hexagonal structure. The first plate 116 and the third plate 114 are used to be connected to the trigger beam 10. The second plate 117 has a connection position trigger surface 111, the V-shaped plate 118 has a test position trigger surface 112, and the fourth plate 119 has a separation position trigger surface 113.

[0081] Furthermore, if Figures 9 to 13 As shown, movable grooves 311 are provided on the two side plates 31 of the drawer seat 30 that are arranged opposite to each other. The movable grooves 311 are L-shaped, one end of the movable grooves 311 extends along the Z axis, and the other end of the movable grooves 311 extends along the X axis. The two ends of the trigger beam 10 are respectively penetrated by the movable grooves 311, so that the trigger beam 10 can move along the Z axis and the X axis respectively relative to the drawer seat 30; a first mounting hole 115 is provided on the first plate 116 of the trigger member 11, and a positioning groove 12 and a second mounting hole 13 are provided on the end of the trigger beam 10 that passes through the side plate 31 and is close to the trigger member 11. The third plate 114 is limitedly inserted in the positioning groove 12 so that the trigger member 11 can be positioned on the trigger beam 10, and the fastener 120 connects the first mounting hole 115 and the second mounting hole 13 to fix the trigger member 11 and the trigger beam 10. Fig.13 As shown, the trigger member 11 can move synchronously with the trigger beam 10. The fastener 120 can be a bolt.

[0082] It is worth noting that the above-mentioned test position trigger surface 112 can trigger the test switch 232 when the trigger member 11 moves downward along the Z-axis. Specifically, due to the limitation of the installation position of the test switch 232, when the trigger member 11 moves downward along the Z-axis to the lowest point, the test position trigger surface 112 does not resist the test switch 232. The trigger member 11 needs to move an appropriate shorter distance along the X-axis direction before the test position trigger surface 112 can trigger the test switch 232.

[0083] During the process of swinging the circuit breaker body in or out, there is a situation that when the circuit breaker body is in the separation position, the shaking operation is directly performed without placing the circuit breaker body, and the shaking operation can drive the trigger beam 10 to move downward along the Z axis. At this time, the trigger beam 10 drives the separation position trigger surface 113 on the trigger member to disengage the separation switch 233; when the trigger beam 10 drives the trigger member 11 thereon to move downward along the Z axis to the lowest point, at this time, the trigger beam 10 no longer moves downward along the Z axis. At this time, since there is no circuit breaker body, the trigger beam 10 cannot be driven to move along the X axis by the inward movement of the circuit breaker body on the X axis. Therefore, in this state, the trigger beam 10 is easy to slide inward along the X axis under the action of external force, and it is easy for the test position trigger surface 112 on the trigger member 11 to be erroneously operated to trigger the test switch 232, and the connection position trigger surface 111 to be erroneously operated to trigger the connection switch 231, resulting in the transmission of the test position signal and the connection position signal when there is no circuit breaker body.

[0084] In order to solve the above problems, Fig.10 and Fig.11 As shown, the circuit breaker further includes an elastic member 60, one end of which is fixedly connected to the side plate 31 of the drawer seat 30, and the other end of the elastic member 60 is horizontally and fixedly connected to the trigger beam 10. When the circuit breaker body is not shaken into the drawer seat 30, when the trigger beam 10 slides inward along the X-axis under the action of external force, the elastic member 60 is stretched; when the external force is removed, the trigger beam 10 can automatically rebound under the elastic action of the elastic member 60, and the test position trigger surface 112 of the trigger member 11 will not be misoperated to trigger the trigger test switch 232, and the connection position trigger surface 111 of the trigger member 11 will not be misoperated to trigger the connection switch 231, that is, the elastic member 60 can keep the position of the trigger beam 10 on the X-axis unchanged when the circuit breaker body is not shaken into the drawer seat 30. The elastic member 60 in this embodiment is specifically a tension spring. In order to ensure a better return effect on the trigger beam 10, the elastic member 60 is provided on both opposite side plates 31 of the drawer seat 30.

[0085] By arranging the elastic member 60 between the trigger beam 10 and the side plate 31 of the drawer seat 30, when the shaking operation is started without shaking the circuit breaker body into the circuit breaker body, it can be ensured that the position of the trigger beam 10 on the X-axis does not change when it moves downward along the Z-axis to the lowest point, and the trigger member 11 will not move inward along the X-axis due to the external force to the test position trigger surface 112 on the trigger member 11 to trigger the test switch 232, and the connection position trigger surface 111 will not trigger the connection switch 231, thereby avoiding the appearance of incorrect indication information of the test position and the connection position when the shaking operation is performed without shaking the circuit breaker body into the circuit breaker body.

[0086] Specifically, Fig.14 and Fig.15As shown, the frame 21 includes a base 212 and a shell 211; wherein the base 212 is connected to the outer side of the side panel 31, and a second mounting groove 2122 and three first mounting grooves 2121 are provided on the base 212, each of the first mounting grooves 2121 is respectively provided with a micro switch 23, and the terminal 22 is installed in the second mounting groove 2122; the shell 211 is located outside the side panel 31 of the drawer seat 30, and the shell 211 is covered outside the base 212 to play a wrapping and supporting role; and an opening 2111 for exposing the terminal 22 is provided on the shell 211, so that the terminal 22 can transmit the electrical signal to the user end.

[0087] Specifically, if Figures 16 to 18 As shown, a protrusion 2123 is provided on one of the housing 211 and the base 212, and a slot 2112 is provided on the other. The protrusion 2123 can be snapped into the slot 2112 to detachably connect the housing 211 and the base 212. In this embodiment, the base 212 is provided with a protrusion 2123, and the housing 211 is provided with a slot 2112.

[0088] Specifically, Fig.16 and Fig.17 As shown, a positioning block 2124 and a buckle 2125 are respectively provided on one of the base 212 and the side plate 31, and a positioning card slot 312 and a connecting slot 313 are respectively provided on the other. The positioning block 2124 is snapped into the positioning card slot 312 to position the base 212 on the side plate 31; the buckle 2125 is snapped into the connecting slot 313 to install the base 212 on the side plate 31, thereby realizing the installation of the entire signal module 20 on the side plate 31 of the drawer seat 30. In this embodiment, a positioning block 2124 and a buckle 2125 are respectively provided on the base 212, and a positioning card slot 312 and a connecting slot 313 are respectively provided on the side plate 31.

[0089] Furthermore, if Fig.11As shown, the trigger beam 10 has a first meshing structure 14, and the first meshing structure 14 can be meshed and connected with the second meshing structure on the circuit breaker body, so that when the circuit breaker body is shaken into or out of the drawer seat 30, the circuit breaker body can drive the trigger beam 10 to move along the X-axis; when the circuit breaker body is shaken in along the X-axis and the test position trigger surface 112 of the trigger member 11 triggers the test switch 232, that is, when the circuit breaker body is in the test position, the first meshing structure 14 can be meshed and connected with the second meshing structure, so that the trigger beam 10 is connected to the circuit breaker body, so that the circuit breaker body can drive the trigger beam 10 along the X-axis. When the circuit breaker body moves outward along the X-axis, since the first meshing structure 14 and the second meshing structure are still meshingly connected, the circuit breaker body can drive the trigger beam 10 to move outward along the X-axis until the test position trigger surface 112 of the trigger member 11 triggers the test switch 232; thereafter, when the circuit breaker body continues to move outward along the X-axis, the shaking operation of the circuit breaker body can drive the trigger beam 10 to move upward along the Z-axis, thereby releasing the meshing connection between the first meshing structure 14 and the second meshing structure.

[0090] Embodiment 2

[0091] In this embodiment, a circuit breaker is proposed, including the circuit breaker body, the drawer seat 30 and the electrical signal device in the first embodiment; the circuit breaker also includes a shaking mechanism and a linkage module, the shaking mechanism is arranged in the drawer seat 30; the linkage module is arranged in the drawer seat 30, and the two ends of the linkage module are respectively connected to the shaking mechanism and the trigger beam 10, the shaking mechanism is used to drive the circuit breaker body to shake in or out along the X axis in the drawer seat 30, and drive the linkage module to move, so that the linkage module can drive the trigger beam 10 to move along the Z axis, and the circuit breaker body can drive the trigger beam 10 to move along the X axis. The circuit breaker in this embodiment is specifically a drawer-type frame circuit breaker, the shaking mechanism is a common structure in existing drawer-type frame circuit breakers, and the shaking mechanism is meshed and connected with the circuit breaker body, so as to be able to drive the circuit breaker body to shake in or out along the X axis in the drawer seat 30.

[0092] Specifically, Fig.19 and Fig. 20As shown, there are two linkage modules, which are respectively connected to the two ends of the trigger beam 10, that is, one linkage module is arranged on one side plate 31; the linkage module includes an intermediate gear 54, a linkage gear 51, a connecting rod 52 and a transmission beam 53; wherein the shaking mechanism includes a shaking body and an intermediate shaft 41, the intermediate shaft 41 extends along the Y axis, the intermediate shaft 41 is rotatably arranged in the drawer seat 30, the shaking body can drive the intermediate shaft 41 to rotate around the Y axis, and a main gear is arranged on the intermediate shaft 41, and a sub-gear meshing with the main gear is arranged on the circuit breaker body, so that the circuit breaker body can be realized through the meshing connection between the main gear and the sub-gear. Rock in or out; the intermediate gear 54 is sleeved on the intermediate shaft 41, the linkage gear 51 is arranged in the drawer seat 30 and rotates around the Y axis, the intermediate gear 54 is meshed and connected with the linkage gear 51, so that the linkage gear 51 can be driven to rotate through the intermediate gear 54, and a linkage shaft 55 is fixedly connected to the linkage gear 51; the connecting rod 52 is arranged in the drawer seat 30 and rotates around the Y axis, and the first end 521 of the connecting rod 52 is linked to the linkage shaft 55; the transmission beam 53 is arranged in the drawer seat 30 and slides along the Z axis, the second end 522 of the connecting rod 52 is connected to one end of the transmission beam 53, and one end of the trigger beam 10 is connected to the other end of the transmission beam 53 slidingly along the X axis.

[0093] Specifically, when the shaking body drives the intermediate shaft 41 to rotate, the main gear on the intermediate shaft 41 drives the secondary gear on the circuit breaker body to rotate, so as to drive the circuit breaker body to move on the X axis; at the same time, the linkage gear 51 on the intermediate shaft 41 rotates to drive the linkage shaft 55 to rotate, so as to drive the connecting rod 52 to rotate through the linkage shaft 55, so as to drive the transmission beam 53 to move up and down on the Z axis, thereby driving the trigger beam 10 to move on the Z axis. Among them, a slide rail 32 extending along the X axis is also provided in the drawer seat 30, and the circuit breaker body can slide on the slide rail 32 to ensure the guidance and stability of the circuit breaker body when it is shaken in or out.

[0094] Furthermore, if Fig.19 and Fig. 20As shown, the first end 521 of the connecting rod 52 has a limiting groove 5211 and an arc surface 5212. The linkage shaft 55 rotates in the limiting groove 5211 to make the separation position trigger surface 113 on the trigger member 11 abut against the separation switch 233. At this time, the circuit breaker body is in the separation position; the linkage shaft 55 rotates at the connection between the arc surface 5212 and the limiting groove 5211 to make the test position trigger surface 112 on the trigger member 11 abut against the test switch 232. At this time, the circuit breaker body is in the test position; since the arc surface 5212 is equal The linkage shaft 55 is a radial arc surface, and it rotates along the arc surface 5212 to the first end 521 of the supporting connecting rod 52, so that the linkage shaft 55 can only rotate to support the first end 521, so that the connecting rod 52 does not rotate, that is, when the linkage shaft 55 rotates along the arc surface 5212, the connecting rod 52 will not drive the transmission beam 53 and the trigger beam 10 to move on the Z axis; when the linkage shaft 55 rotates along the arc surface 5212 to the edge position of the arc surface 5212, the connection position trigger surface 111 on the trigger member 11 can trigger the connection switch 231.

[0095] Specifically, if Fig.21 As shown, the initial position of the linkage shaft 55 is located in the limit groove 5211. At this time, the separation position trigger surface 113 on the trigger member 11 always abuts against the separation switch 233, the connecting rod 52 is horizontally arranged, and the transmission beam 53 and the trigger beam 10 are both in the highest position; at the same time, the circuit breaker body is manually pushed into the drawer seat 30. When the circuit breaker body abuts against the preset limit member in the drawer seat 30, it means that the circuit breaker body has reached the separation position.

[0096] Then, if Fig. 20 As shown, by shaking the main body, the intermediate shaft 41 is driven to rotate, so that the intermediate gear 54 drives the linkage gear 51 as shown in FIG. Fig. 20 The linkage shaft 55 rotates counterclockwise as indicated by the arrow B in the figure, so that the linkage shaft 55 cooperates with the first end 521 of the compression connecting rod 52, so that the linkage shaft 55 can drive the connecting rod 52 to rotate clockwise, so that the second end 522 of the connecting rod 52 drives the transmission beam 53 as shown in FIG. Fig. 20 When the linkage shaft 55 rotates to the arc surface 5212, the test position trigger surface 112 on the trigger member 11 abuts against the test switch 232, as shown in the arrow C in FIG. Fig. 22 As shown, at this time, the second end 522 of the connecting rod 52 no longer drives the transmission beam 53 to move downward along the Z axis, and the circuit breaker body can move inward along the X axis under the driving action of the shaking body until the trigger beam 10 is connected to the circuit breaker body.

[0097] It is worth noting that, in the process of the circuit breaker body driving the trigger beam 10 to move inwardly along the X-axis, at this time, since the shaking body is always working, the shaking body can drive the circuit breaker body to move inwardly along the Z-axis while also driving the linkage gear 51 and the linkage shaft 55 to rotate. At this time, the test position trigger surface 112 on the trigger member 11 has triggered the test switch 232, so it is no longer necessary for the transmission beam 53 to drive the trigger beam 10 to continue to move downward along the Z-axis. Therefore, during this process, the linkage shaft 55 rotates along the arc surface 5212 of the connecting rod 52, so as to ensure that the transmission beam 53 does not continue to move downward along the Z-axis, while avoiding the linkage gear 51, the linkage shaft 55 and the connecting rod 52 from interfering with the movement of the trigger beam 10 on the X-axis, thereby ensuring that the trigger beam 10 can move smoothly on the X-axis.

[0098] It is worth noting that when the circuit breaker body is not shaken into the drawer seat 30 and the shaking body is working, since the shaking body can drive the linkage shaft 55 to rotate, it can drive the trigger beam 10 to move downward along the Z axis to the lowest point; at this time, since the connecting rod 52 has a limiting effect on the trigger beam 10 on the Z axis, the elastic member 60 cannot automatically rebound the trigger beam 10 on the Z axis; and since there is no limiting effect of the circuit breaker body on the trigger beam 10 on the X axis, the elastic member 60 can provide automatic rebound force for the trigger beam 10 on the X axis when the external force is removed, so as to ensure that the position of the trigger beam 10 on the X axis remains unchanged when it moves downward along the Z axis to the lowest point, thereby ensuring that when the circuit breaker body is not connected to the trigger beam 10, the test position trigger surface 112 of the trigger member 11 will not trigger the trigger test switch 232, and the connection position trigger surface 111 of the trigger member 11 will not trigger the connection switch 231.

[0099] The specific process of swinging the circuit breaker body into the drawer seat 30 in this embodiment is as follows:

[0100] First, if Fig.21 As shown, the initial position of the linkage shaft 55 is located in the limit groove 5211. At this time, the separation position trigger surface 113 on the trigger member 11 always abuts against the separation switch 233, the connecting rod 52 is horizontally arranged, and the transmission beam 53 and the trigger beam 10 are both in the highest position; at the same time, the circuit breaker body is manually pushed into the drawer seat 30. When the circuit breaker body abuts against the preset limit member in the drawer seat 30, it means that the circuit breaker body has reached the separation position.

[0101] Then, the shaking mechanism is controlled to work, so as to drive the circuit breaker body to shake into the drawer seat 30 along the X-axis through the shaking mechanism. At the same time, the shaking mechanism drives the linkage gear 51 to rotate counterclockwise, so that the linkage shaft 55 presses the first end 521 of the connecting rod 52, so that the first end 521 of the connecting rod 52 is subjected to an upward force and moves upward. Under the action of the rotation center, the second end 522 of the connecting rod 52 synchronously drives the transmission beam 53 to move downward along the Z-axis, so as to be able to drive the trigger beam 10 to move downward along the Z-axis. In the process of the trigger beam 10 moving downward, the first meshing structure 14 on the trigger beam 10 gradually approaches the second meshing structure on the circuit breaker body, so that the first meshing structure 14 is in contact and meshed with the second meshing structure.

[0102] Since the first end 521 of the connecting rod 52 is provided with an arc surface 5212 of equal radius, when the linkage gear 51 and the linkage shaft 55 rotate to a certain angle on the arc surface 5212, the linkage shaft 55 only provides a rotation support force to keep the connecting rod 52, so the transmission beam 53 drives the trigger beam 10 to move downward along the Z axis to a certain position and then stops. Fig. 22 As shown, at this time, the test position trigger surface 112 on the trigger member 11 triggers the test switch 232, and the circuit breaker body is located at the test position. The moving distance of the trigger beam 10 on the Z axis matches the size of the movable slot 311 set on the side plate 31.

[0103] Finally, the circuit breaker body drives the trigger beam 10 to move inward along the X-axis relative to the transmission beam 53 until the connection position trigger surface 111 on the trigger member 11 on the trigger beam 10 triggers the connection switch 231. At this time, the circuit breaker body is in the connection position, such as Fig.23 In the process of triggering the cross beam 10 to move along the X-axis, the linkage shaft 55 rotates along the arc surface 5212 of the connecting rod 52 .

[0104] The movement process of the circuit breaker body from the connected position to the disconnected position is opposite to the above process and will not be described in detail here.

[0105] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
