[0001] The invention relates to the field of low-voltage electrical appliances, and in particular to an isolating switch. Background Art

[0002] The existing rotary isolating switch includes an operating mechanism and a switch body. The switch body includes at least one set of switch units. The operating mechanism is connected to the moving contact mechanism of the switch unit to drive the switch unit to close and open. The operating mechanism adopts the existing four-link-five-link switching structure, so that when the rotating handle of the operating mechanism is blocked, it can still reliably open the switch. Among them, the operating mechanism is provided with an output member, which is connected to the moving contact mechanism through a transmission shaft pin. The rotating shaft, the transmission shaft pin and the supporting shaft are coaxially arranged. The above connection method increases the structural complexity of the rotating shaft and the supporting shaft, and the reliability and stability are poor; in addition, the creepage distance and insulation gap between the operating mechanism and the switch body are insufficient, and there is still a situation where the operating mechanism and the switch body are short-circuited, resulting in electric shock to the operator.

[0073] The specific implementation of the isolating switch of the present invention is further described below in conjunction with the embodiments given in the accompanying drawings. The isolating switch of the present invention is not limited to the description of the following embodiments.

[0074] like Figure 1-3 FIG. 1 is an embodiment of the isolating switch of the present invention. The isolating switch of this embodiment is preferably a rotary isolating switch.

[0075] The isolating switch of this embodiment includes an operating mechanism 100 and a switch body 200. The switch body 200 includes at least one set of switch units 200u. The switch unit 200u includes a contact system. The contact system includes a movable contact mechanism 200-1u that is rotatably arranged and a static contact that cooperates with the movable contact mechanism 200-1u. The operating mechanism 100 is connected to the movable contact mechanism 200-1u of each switch unit 200u by transmission, and drives each movable contact mechanism 200-1u to rotate and close and disconnect with the corresponding static contact, so that the isolating switch is closed and opened. Further, the movable contact mechanism 200-1u includes a supporting shaft 200-10u that is rotatably arranged, and each supporting shaft 200-10u is connected to the operating mechanism 100 by transmission. Further, the operating mechanism 100 and the switch body 200 are stacked along the rotation axis of the movable contact mechanism 200-1u. Furthermore, the switch body 200 includes two or more switch units 200u, each switch unit 200u is stacked along the rotation axis of the moving contact mechanism 200-1u, and the contact system of each switch unit 200u is closed and opened synchronously.

[0076] The isolating switch of this embodiment further includes a rotating handle 300, which is transmission-connected to the operating mechanism 100. The rotating handle 300 is driven to rotate by an external force, and the rotating handle 300 drives the operating mechanism 100 to complete the closing, opening and resetting operations. The resetting operation refers to the operation of restoring the snap-fitting of the tripping member 15 and the locking member 21 of the operating mechanism 100 after the operating mechanism 100 is tripped (for example, the tripping is achieved by remote control or the tripping is driven by a thermal magnetic tripping mechanism). Further, the rotating handle 300 is transmission-connected to the drive shaft structure of the operating mechanism 100. Specifically, the rotating handle 300 is transmission-connected to the drive shaft 1 of the drive shaft structure, which will be described later.

[0077] like Figure 2-14 FIG. 1 is an example of an embodiment of the operating mechanism 100 .

[0078] The operating mechanism 100 of this embodiment includes a mechanism bracket s, a connecting rod structure, a drive shaft structure, at least one group of transmission structures 23t and an output structure; the output structure includes an output member 10; the connecting rod structure includes a buckle structure, the buckle structure has a buckle state and a release state, the buckle structure includes a buckle jumper 15 and a lock member 21 that are buckled together, the buckle structure is in the buckle state when the buckle jumper 15 and the lock member 21 are buckled together, and the buckle structure enters the release state when the buckle jumper 15 and the lock member 21 are released, the connecting rod structure also includes a rocker arm 6, a first connecting rod 11, a second connecting rod 12, and a main spring 16; the rocker arm 6, the drive shaft structure, the buckle jumper 15, the lock member 21 and the output member 10 are rotatably arranged on the mechanism bracket s respectively; the drive shaft structure is connected to the transmission structure 2 3t is connected to the rocker arm 6 for transmission, the driving shaft structure is driven to rotate by an external force (for example, the driving force from the knob 300), and the rocker arm 6 is driven to swing back and forth through the transmission structure 23t to switch between the open position and the closed position, driving the operating mechanism 100 to close and open the switch, the second connecting rod 12 is connected to the tripping member 15 for rotation around the third axis 1215s, the second connecting rod 12 is connected to the first connecting rod 11 for rotation through the second axis 1112s, the first connecting rod 11 is connected to the output member 10 for rotation through the first axis 1011s, the first axis 1011s, the second axis 1112s and the third axis 1215s are arranged parallel to each other and spaced apart, one end of the main spring 16 is connected to the rocker arm 6 and the other end is connected to the second axis 1112s, and the output member 10 is also used to be connected to the moving contact mechanism 200-10u for transmission. Furthermore, the rocker arm 6 is also used to drive the jumper 15 and the lock member 21 to resume the snap fit; the connecting rod structure also includes a stopper, which is used to cooperate with the second connecting rod 12 to prevent it from continuing to rotate when the operating mechanism 100 is closed; the operating mechanism 100 also includes a jumper stop shaft 17 fixedly arranged on the mechanism bracket s, and when the operating mechanism 100 is tripped, the jumper 15 and the jumper stop shaft 17 are limitedly cooperated to prevent the jumper 15 from continuing to rotate; after the operating mechanism 100 is tripped, the lock member 21 and the jumper 15 are abutted against each other to prevent the lock member 21 from resetting, thereby avoiding the formation of a dead lock when the lock member 21 and the jumper 15 resume the snap fit, and in the whole process of the rocker arm 6 driving the jumper 15 to rotate to resume the snap fit with the lock member 21, the jumper 15 always presses the lock member 21 until the two resume the snap fit.

[0079] Furthermore, the operating mechanism 100 also includes a mechanism housing, and the above structures (including the mechanism bracket s, the connecting rod structure, the drive shaft structure, the transmission structure 23t and the output member 10) are all arranged in the mechanism housing. The operating mechanism 100 of this embodiment adopts the four-link-five-link switching scheme of the prior art. When the operating mechanism 100 is in the closed state, after the jumper 15 and the locker 21 release the buckle cooperation, that is, after the buckle structure switches from the buckle state to the tripped state, the four-link-five-link mechanism of the operating mechanism 100 disintegrates, and under the action of the main spring 16, the connecting rod structure drives the output member 10 to rotate and switch between the closed position and the disconnected position, and the output member 10 drives the supporting shaft 200-10u of the moving contact mechanism 200-1u to rotate to the disconnected position, so that the contact system of the switch unit 200u is disconnected. The isolating switch of the present invention adopts the operating mechanism 100 of this embodiment, and even if the knob 300 is blocked and cannot be rotated, the operating mechanism 100 can still trip and open the switch to ensure the safety of electricity use. Specifically, one end of the second connecting rod 12 is connected to the jumper 15 for rotation around the third axis 1215 and the other end is connected to one end of the first connecting rod 11 for rotation around the second axis 1112s, and the other end of the first connecting rod 11 is connected to the output member 10 for rotation around the first axis 1011s; one end of the main spring 16 is connected to the rocker beam 6-01 of the rocker arm 6 and the other end is connected to the second axis 1112s; the jumper 15 is rotatably set on the mechanism bracket s through the jumper shaft 15s, and the jumper shaft 15s serves as a stopper.

[0080] like Figure 2 , 4 -5, 12, the rocker arm 6 comprises a rocker arm cross beam 6-01 and a rocker arm leg 6-02, the two rocker arm legs 6-02 are arranged opposite to each other, one end is bent and connected to the rocker arm cross beam 6-01 and the other end is respectively rotatably arranged on the mechanism bracket s. Further, the two rocker arm legs 6-02 are respectively rotatably arranged on the two side plates of the mechanism bracket s through a rocker arm shaft.

[0081] Further, such as Figure 4-5 As shown in Figures 12, the rocker arm cross beam 6-01 and the two rocker arm legs 6-02 are in a U-shaped structure as a whole.

[0082] Further, such as Figure 6-8.2 As shown, the rocker arm 6 also includes a reset portion 6-2, which is arranged on the rocker arm leg 6-02, and the jumper 15 includes a reset protrusion 15-1; after the operating mechanism 100 is tripped, the rocker arm 6 is in the tripped position, and when it swings to the opening position, the reset portion 6-2 presses the reset protrusion 15-1 to reset it to restore the snap fit with the lock member 21. Further, the reset portion 6-2 is a reset plate bent and connected to the rocker arm leg 6-02, and the reset protrusion 15-1 includes a reset protrusion arc surface, and the reset plate presses the reset protrusion arc surface to reset the jumper 15 to restore the snap fit with the lock member 21.

[0083] Further, such as Figure 4-5 As shown in Figures 7 and 8, the rocker arm 6 is limitedly matched with the mechanism bracket s at both ends of its rotation stroke to limit the rocker arm 6 in the opening position and the closing position. Further, the mechanism bracket s includes an opening position blocking portion 4-2 and a closing position blocking portion, and the opening position blocking portion 4-2 and the closing position blocking portion are respectively limitedly matched with the rocker arm 6 to limit the rocker arm 6 in the opening position and the closing position. Further, the opening position blocking portion 4-2 is limitedly matched with a side edge of the rocker leg 6-02, and the closing position blocking portion is limitedly matched with the reset portion 6-2 on the rocker leg 6-02. Further, the opening position blocking portion 4-2 is limitedly matched with the rocker arm blocking surface 6-1 provided on the side edge of the rocker leg 6-02 to limit the rocker arm 6 in the opening position.

[0084] Specifically, Figure 4-5 As shown in Figure 7, a reset portion 6-2 is provided on each of the two rocker arm legs 6-02, and the two reset portions 6-2 are bent toward each other between the two rocker arm legs 6-02. A reset protrusion 15-1 is provided on each of the two jumper support arms 15-01 of the jumper 15, and an opening position blocking portion 4-2 and a closing position blocking portion are provided on the two side panels of the mechanism bracket s.

[0085] Combination Figure 6-7 As shown, when the operating mechanism 100 of this embodiment switches between the closing state and the opening state, the rotation angle of the output member 10 is 80°-110°, preferably 90°-100°. The above design can significantly increase the opening distance between the moving contact mechanism 200-1u and the static contact.

[0086] like Figure 3-10 As shown, the operating mechanism 100 also includes a refastener 20 rotatably disposed on the mechanism bracket s, and the refastener 20 is limitedly matched with the lock member 21. The refastener 20 is driven by an external force (for example, from a thermal magnetic tripping mechanism for realizing short circuit and / or overload protection functions (the thermal magnetic tripping mechanism can be an integrated mechanism, or can include a separate short circuit protection mechanism and / or thermal protection mechanism) and / or a tripping module 500 for realizing remote tripping control) to rotate, releasing the limited cooperation with the lock member 21, and the lock member 21 rotates to release the snap-fit ​​cooperation with the jumper 15, and the snap-fit ​​structure switches from the snap-fit ​​state to the tripping state, driving the operating mechanism 100 to trip. Further, the refastener 20 also includes a refastener limiting shaft 20-1, and the mechanism bracket s is provided with a bracket limiting hole 4-1, and the refastener limiting shaft 20-1 is swingably set in the bracket limiting hole 4-1 to realize the limitation of the rotation stroke of the refastener 20.

[0087] Further, such as Figure 9-10As shown, the operating mechanism 100 also includes a reset spring 70, which is a torsion spring and is sleeved on the lock shaft 21s. The two ends of the reset spring 70 are located between the refastener 20 and the lock member 21, one end cooperates with the refastener 20 (the end is the spring second end 70-2) and the other end cooperates with the lock member 21 (the end is the spring first end 70-1), so that the refastener 21 and the lock member 20 have a tendency to rotate in opposite directions; the reset spring 70 acts on the lock member 21 to keep it in the snap-fit ​​position with the jumper 15. Further, the lock member 21 also includes a lock member positioning part 21-1, and the mechanism bracket s includes a bracket positioning part 5-1. The lock member positioning part 21-1 and the bracket positioning part 5-1 are limitedly matched to limit the limit position of the reset spring 70 driving the lock member 21 to rotate, so as to avoid the lock member 21 and the refastener 15 from forming a dead lock, which affects the release action of the operating mechanism 100.

[0088] Further, such as Figure 6-7 9-10 The refastener 20 includes a refastener limiting portion 20-5, and the lock 21 includes a lock limiting portion 21-5. The refastener limiting portion 20-5 abuts against one side of the lock limiting portion 21-5 to keep the lock 21 and the jumper 15 in a snap-fitting manner. Further, the refastener 20 also includes a refastener operating portion, which is limited and matched with the refastener limiting portion 20-5 and is an L-shaped structure as a whole. The bending part of the two is rotatably arranged on the mechanism bracket s, and one end of the reset spring 70 is matched with the refastener operating portion, and the other end is matched with the lock 21; one end of the lock 21 is the lock limiting portion 21-5, and the other end is rotatably arranged on the mechanism bracket.

[0091] like Figure 2 , 4 -5, the drive shaft structure and the output member 10 are coaxially rotatably arranged. Further, the drive shaft structure and the output member 10 are both rotatably arranged around the first axis o1-o1 on the mechanism bracket s, which is conducive to making the structure of the operating mechanism 100 more compact and reducing space requirements. Specifically, the drive shaft structure and the output member 10 are both rotatably arranged around the first axis o1-o1.

[0092] Further, the drive shaft structure includes a drive shaft 1 rotatably arranged on the mechanism bracket s around a first axis o1-o1, the first axis o1-o1 passes through the middle of the drive shaft 1, and the axis of the drive shaft 1 preferably coincides with the first axis o1-o1; the transmission structure 23t includes a first transmission connecting rod 2 and a second transmission connecting rod 3, the first transmission connecting rod 2 is arranged on the drive shaft 1 and rotates synchronously therewith, and the two ends of the second transmission connecting rod 3 are respectively connected to the first transmission connecting rod 2 and the rocker arm 6. Further, the two ends of the second transmission connecting rod 3 are respectively connected to the first transmission connecting rod 2 and the rocker arm 6. Further, one end of the second transmission connecting rod 3 is connected to the first transmission connecting rod 2 for rotation, and the other end is connected to the rocker leg 6-02 of the rocker arm 6 for rotation.

[0093] like Figure 2 , 4 -5, the rocker arm 6 also includes a connecting toe 6-03, at least one rocker arm leg 6-02 is provided with a connecting toe 6-03 and is transmission-connected to the transmission structure 23t through the connecting toe 6-03, and the connecting toe 6-03 is preferably transmission-connected to the second transmission connecting rod 3 of the transmission structure 23t. Further, the rocker arm cross beam 6-02 and the connecting toe 6-03 are respectively located on both sides of the rotation axis of the rocker arm 6.

[0094] Specifically, the driving shaft 1 is rotatably inserted on the mechanism bracket s, and one end protrudes from one side of the two side plates of the mechanism bracket s for fixed connection with the rotating handle 300; the two groups of the transmission structures 23t are respectively arranged on the two sides of the two side plates of the mechanism bracket s, and the two rocker legs 6-02 of the rocker arm 6 are respectively arranged on the two sides of the two side plates of the mechanism bracket s and are both provided with connecting toes 6-03, and the two connecting toes 6-03 are respectively connected to the two groups of transmission structures 23t by transmission, and the two connecting toes 6-03 are preferably respectively connected to the two second transmission connecting rods 3 of the two groups of transmission structures 23t by transmission.

[0095] like Figure 3-8.1 As shown, the operating mechanism 100 of this embodiment also includes a buffer 41. When the operating mechanism 100 is opened, the output structure hits and rests on the buffer 41. That is, when the operating mechanism 100 is opened, the output structure hits the buffer 41 to stop the output structure from rotating (also stops the output member 10 from rotating). The output structure finally rests on the buffer 41 and stays in the disconnected position. At this time, the output structure also drives the moving contact mechanism 200-1u to stay in its disconnected position. The buffer 41 is made of a flexible material, such as plastic, rubber, etc., and plays a buffering role for the operating mechanism 100, ensuring that the operating mechanism 100 will not be disengaged due to hard impact during the opening process, causing the operating mechanism 100 to disintegrate. Further, the linkage shaft 40 of the output structure hits and rests on the buffer 41 when the operating mechanism 100 is opened. Furthermore, the buffer 41 includes a buffer assembly part and a buffer buffer part, the buffer 41 is fixed to the mechanism bracket s through the buffer assembly part, the buffer buffer part is arranged on the buffer assembly part, and the buffer buffer part is a V-shaped plate structure, both ends of which are respectively connected to the buffer assembly part and the tip is facing the output member 10. Of course, the buffer buffer part can also be a structure of other shapes, such as an arc plate, a corrugated plate or a single-layer plate, etc., and there are many other forms, which are not listed here one by one.

[0096] Specifically, when the operating mechanism 100 of this embodiment is in the closed state, the linkage shaft 40 of the output structure abuts against one end of the upper arc hole 4-3 and the lower arc hole 5-3 of the mechanism bracket s; and / or, when the operating mechanism 100 of this embodiment is in the open or tripped state, the linkage shaft 40 abuts against the other end of the upper arc hole 4-3 and the lower arc hole 5-3 to prevent the linkage shaft 40 from continuing to rotate around the first axis o1-o1; the upper arc hole 4-3 and the lower arc hole 5-3 will be described later.

[0097] As another embodiment, the operating mechanism 100 of this embodiment does not have a buffer member 41, but a buffer structure is provided at one end of the upper arc hole 4-3 and the lower arc hole 5-3. When the operating mechanism 100 is opened or tripped, the linkage shaft 40 collides with and finally rests on the buffer structure.

[0098] like Figure 2-8.1 As shown in Figures 13-14, the first improvement of the isolating switch in this embodiment is that: the operating mechanism 100 also includes a linkage shaft 40, and the switch body 200 also includes a turntable 60, which is fixedly connected to the supporting shaft 200-10u of the moving contact mechanism 200-1u and is arranged between the linkage shaft 40 and the supporting shaft 200-10u, and the output member 10 is connected to the turntable 60 through the linkage shaft 40 to drive the turntable 60 to reciprocate, and the turntable 60 is coaxially connected to the supporting shaft 200-10, and the output member 10, the turntable 60 and the supporting shaft 200-10u of the moving contact mechanism 200-1u are all rotatably arranged around the first axis o1-o1, and the axis of the linkage shaft 40 is the second axis o2-o2 arranged parallel to the first axis o1-o1 and spaced apart. The output member 10+ linkage shaft 40+ turntable 60 drives the moving contact mechanism 200-1u to rotate, which is beneficial to increase the creepage distance and insulation gap between the operating mechanism 100 and the switch body 200, ensure the personal safety of the operator, and avoid electric shock accidents caused by short circuit between the operating mechanism 100 and the switch body 200. Further, the turntable 60 is arranged on the outside of a side plate of the mechanism bracket s, and one end of the linkage shaft 40 passes through the side plate and is connected to the turntable 60 by transmission. The side plate is preferably the lower side plate 5 of the mechanism bracket s (that is, the side plate close to the switch body 200). Further, the turntable 60 and the linkage shaft 40 are arranged in the mechanism housing. Specifically, the turntable 60 and the supporting shaft 200-10u are both arranged to rotate around the first axis o1-o1, and the first axis o1-o1 passes through the middle of the turntable 60 and the supporting shaft 200-10u.

[0099] like Figure 13-14 As shown, the rotating disk 60 is connected to the adjacent supporting shafts 200-10u by means of a plug-in structure. Further, in the switch body 200, each adjacent supporting shaft 200-10u is connected to each other by means of a plug-in structure. The above structural design is conducive to simplifying the assembly operation and improving the assembly efficiency.

[0100] Specifically, the plug-in structure includes a plug and a jack, one of which is arranged on the supporting shaft 200-10u and the other is arranged on the turntable 60, that is, one of the supporting shaft 200-10u and the turntable 60 is provided with a plug and the other is provided with a jack. In this embodiment, the plug is preferably arranged on the supporting shaft 200-10u, and the jack is preferably arranged on the turntable 60; the plug includes a main plug 200-101u and a secondary plug 200-100u, and the first axis o1-o1 passes through the middle of the main plug 200-101u, and two groups of secondary plugs 200-100u are respectively arranged on both sides of the main plug 2001-101u; the jack includes a main jack 60-5 and a secondary jack 60-6, which correspond to the main plug 200-101u and the secondary plug 200-100u respectively, and the two groups of secondary jacks 60-6 are respectively arranged on both sides of the main jack 60-5. Furthermore, in the plug-in structure of the turntable 60 and the supporting shaft 200 - 10u, the jack is arranged on the turntable 60 , and the plug is arranged on the supporting shaft 200 - 10u .

[0101] Furthermore, the cross section of the main plug 200-101u is a long strip structure, the cross section of the auxiliary plug 200-100u is a fan-shaped structure, and the two sets of auxiliary plugs 200-100u are symmetrically arranged on both sides of the main plug 200-101u. Furthermore, the centers of the two sets of auxiliary plugs 200-100u are on the first axis o1-o1.

[0102] Combination Figure 2 , 13 -14, the turntable 60 includes a turntable connecting hole 60-1, which is located on one side of the rotation center of the turntable 60, that is, the turntable connecting hole 60-1 is located on one side of the first axis o1-o1, and the linkage shaft 40 is rotatably inserted in the turntable connecting hole 60-1; when the output member 10 rotates back and forth, the turntable 60 is driven to rotate around the first axis o1-o1 by cooperating with the linkage shaft 40 and the turntable connecting hole 60-1.

[0103] Furthermore, the turntable 60 also includes a reinforced enclosure 60-10, which is arranged on the outer side of one end of the turntable connecting hole 60-1 facing the mechanism bracket s. The reinforced enclosure 60-10 is beneficial to enhancing the structural strength of the turntable connecting hole 60-1 and extending the service life of the turntable 60.

[0104] like Figure 13-14As shown, the turntable 60 also includes a turntable main board 60-3 and a turntable shaft base 60-2, the turntable connecting hole 601- is set on the turntable main board 60-3, and the turntable shaft base 60-2 is set on the side of the turntable main board 60-3 away from the mechanism bracket s, that is, the turntable shaft base 60-2 is set on the side of the turntable main board 60-3 facing the switch body 200; the mechanism housing of the operating mechanism 100 is provided with a turntable shaft hole, and the turntable shaft base 60-2 is rotatably set in the turntable shaft hole.

[0105] Furthermore, the entrance of the socket of the turntable 60 is arranged on the turntable shaft platform 60 - 2 , that is, the plug supporting the rotating shaft 200 - 10u is inserted into the socket of the turntable 60 facing the turntable shaft platform 60 - 2 .

[0106] like Figure 2 -8, the mechanism bracket s is provided with a linkage shaft guide structure, and the linkage shaft 40 cooperates with the linkage shaft guide structure to limit the rotation trajectory of the linkage shaft 40 around the first axis o1-o1. Further, the output member 10 is rotatably arranged between the two side plates of the mechanism bracket s; the linkage shaft guide structure includes an upper guide structure and a lower guide structure respectively arranged on the upper side plate 4 and the lower side plate 5 of the mechanism bracket s; the middle part of the linkage shaft 40 is inserted into the output member 10, one end cooperates with the upper guide structure, and the other end cooperates with the lower guide structure and is connected to the turntable 60 after passing through the lower side plate 5. When the isolating switch is in the open state and the tripped state, that is, when the operating mechanism 100 is in the open state and the tripped state, the linkage shaft 40 is preferably respectively limited with one end of the upper guide structure and the lower guide structure to prevent the linkage shaft 40 from continuing to rotate.

[0107] Specifically, the upper guide structure is an upper arc hole 4-3, the lower guide structure is a lower arc hole 5-3, the linkage shaft 40 is inserted into the upper arc hole 4-3 and the lower arc hole 5-3 respectively, and the shapes of the upper arc hole 4-3 and the lower arc hole 5-3 match the rotation trajectory of the linkage shaft 40. The linkage shaft guide structure has a simple structure and simple cooperation with the linkage shaft 40, and can reliably limit the rotation trajectory of the linkage shaft 40, thereby ensuring that the output member 10 reliably drives the rotating disk 60 to rotate. Furthermore, when the disconnector is in the open state and the tripped state, the linkage shaft 40 is limitedly cooperated with one end of the upper arc hole 4-3 and the lower arc hole 5-3 respectively to prevent the linkage shaft 40 from continuing to rotate. Of course, the transmission rod guide structure is not limited to the above-mentioned implementation method. For example, the upper guide structure can also be an arc groove arranged on the upper side plate 4, and the lower guide structure can be two arc ribs arranged relatively spaced apart on the lower side plate 5. Technical personnel in this field can also make other deformations, which are not listed one by one here, and all kinds of deformations should fall within the protection scope of the transmission rod guide structure of this application.

[0108] Furthermore, the linkage shaft 40 includes a coaxially arranged linkage shaft trunk and a linkage shaft annular platform, the outer diameter of the linkage shaft annular platform is larger than the outer diameter of the linkage shaft trunk, and the linkage shaft annular platform is arranged in the middle of the linkage shaft trunk and between the lower side plate 5 and the output member 10, thereby preventing the linkage shaft 40 from moving along its axial direction and ensuring reliable cooperation among the linkage shaft 40, the output member 10, the mechanism bracket s and the turntable 60.

[0109] like Figure 2-8.1 As shown, the second improvement of the isolating switch in this embodiment is that the operating mechanism 100 in this embodiment also includes an auxiliary spring 30 acting on the tripping member 15. After the locking member 21 and the tripping member 15 are released from the snap fit, the main spring 16 and the auxiliary spring 30 are used to drive the tripping member 15 to rotate in the same direction, that is, the main spring 16 and the auxiliary spring 30 both apply forces to the tripping member 15, and the two forces both cause the tripping member 15 to rotate in the same direction. The tripping member 15 rotates and moves away from the locking member 21, and after rotating in the tripping direction to the tripping position, it cooperates with the rocker arm 6 to limit the tripping member 16 and the rocker arm 6 to keep relatively still. The main spring 16 and the auxiliary spring 30 cooperate to significantly improve the collapse speed and tripping speed of the operating mechanism 100, and reduce the action time of the operating mechanism 100. Moreover, the main spring 16 and the auxiliary spring 30 can drive the moving contact mechanism 200-1u to rotate toward the disconnecting position through the jumper 15, the second connecting rod 12, the first connecting rod 11 and the output member 10, which helps to improve the breaking efficiency of the moving contact mechanism 200-1u and the static contact, and improve the breaking capacity of the disconnector.

[0110] Further, such as Figure 3-8.1 As shown, the middle part of the jumper 15 is rotatably arranged on the mechanism bracket s, one end of which is snap-fitted with the lock member 21, and the other end is connected to the auxiliary spring 30. Further, one end of the auxiliary spring 30 is connected to the jumper 15, and the other end is fixedly arranged on the mechanism bracket s. Further, the mechanism bracket s is provided with a bracket hanging spring part, the jumper 15 is provided with a jumper hanging spring part, and the two ends of the auxiliary spring 30 are respectively connected to the bracket hanging spring part and the jumper hanging spring part. Further, the bracket hanging spring part and / or the jumper hanging spring part are hooks or hanging holes. It should be pointed out that the setting position of the auxiliary spring 30 and the matching mode with the jumper 15 are not limited to the above description. The setting of the auxiliary spring 30 only needs to meet the following conditions: after the jumper 15 and the lock member 21 are released from the snap-fit, the force acting on the jumper 15 by the auxiliary spring 30 and the main spring 16 is used to drive the jumper 15 to rotate in the tripping direction, and it does not interfere with other components of the operating mechanism 100.

[0111] Further, combined with Figure 3-8.1As shown in Figures 11, the jumper 15 includes a jumper crossbeam 15-00 and a jumper support arm 15-01. The two jumper support arms 15-01 are opposite to each other, one end of which is bent and connected to the jumper crossbeam 15-02 and the other end is connected to two groups of auxiliary springs 30. Further, the middle parts of the two jumper support arms 15-01 are respectively rotatably arranged on the two side plates of the mechanism bracket s, and the middle parts of the two jumper support arms 15-01 are respectively rotatably arranged on the two side plates of the mechanism bracket s through a jumper shaft 15s. Further, the jumper support arm 15-01 is provided with a jumper stop surface 15-3. When the operating mechanism 100 is tripped, the jumper stop surface 15-3 abuts against the jumper stop shaft 17 to prevent the jumper 15 from continuing to rotate; the jumper stop surface 15-3 is preferably arranged on the side edge of the middle part of the jumper 15, close to the jumper shaft 15s and located on one side thereof.

[0112] Further, such as Figure 6-8.2 As shown in Figures 11, the jumper 15 also includes a jumper buckle portion 15-02, which is arranged on the jumper cross beam 15-02 and is used to buckle with the locker 21. Further, the locker 21 includes a lock lap surface, which cooperates with the jumper lap 15-02 to achieve the buckle fit between the locker 21 and the jumper 15; when the operating mechanism 100 is in the closed state, the lock lap surface and the jumper lap 15-02 are relatively overlapped, and the jumper lap 15-02 is inclined relative to the lock lap surface; when the operating mechanism 100 is in the open state, the lock lap surface and the jumper lap 15-02 are opposite and there is a gap between them to ensure the reliable overlap between the lock lap surface and the jumper lap 15-02. Furthermore, when the operating mechanism 100 is in the closed state, after the fastener 20 and the lock member 21 are released from the limiting fit, the jumper 15-02 presses against the lock overlap surface to make the jumper 15 and the lock member 21 rotate in opposite directions, thereby releasing the lock member 21 from the jumper 15.

[0113] Further, such as Figure 8.2-10 As shown, the locking member 21 also includes a locking member mating arm 21-6. After the operating mechanism 100 is disengaged, the jumping member beam 15-00 of the jumping member 15 presses against the locking member mating arm 21-6 to prevent the locking member 21 from resetting. Moreover, in the process where the rocker arm 6 drives the jumping member 15 to rotate to restore the snap fit with the locking member 21, the jumping member beam 15-00 always presses against the locking member mating arm 21-6. Furthermore, the locking member mating arm 21-6 is arranged on the locking member limiting portion 21-5.

[0114] Further, such as Figure 4-5As shown in 11, the second connecting rod 12 includes two second connecting rod side plates 12-0 arranged oppositely, the first connecting rod 11 includes two first connecting rod side plates 11a arranged oppositely, the two jumper support arms 15-01 are rotatably connected to the two second connecting rod side plates 12-0 through a third shaft 1215s, the two second connecting rod side plates 12-0 are rotatably connected to the two first connecting rod side plates 11a through a second shaft 1112s, and the two first connecting rod side plates 11a are rotatably connected to the output member 10 through a first shaft 1011s; one end of the two groups of main springs 16 is connected to the rocker arm 6 and the other end is connected to the first shaft 1011s. Further, the first connecting rod 11 also includes a first connecting rod connecting plate 11b, and the two first connecting rod side plates 11a are respectively bent and connected to the first connecting rod connecting plate 11b. Specifically, one end of the two second connecting rod side plates 12-0 is rotatably connected to the two jumper support arms 15-01 of the jumper 15, and the other end is rotatably connected to one end of the two first connecting rod side plates 11a, respectively, and the other end of the two first connecting rod side plates 11a is rotatably connected to the output member 10. It should be noted that the first connecting rod 11 is only provided with one first connecting rod side plate 11a, and / or the second connecting rod 12 is only provided with one second connecting rod side plate 12-0, but this will affect the stability and reliability of the operating mechanism 100.

[0115] Further, such as Figure 4-5 As shown in , 11, the output member 10 includes an output member side plate 10a and an output member connecting plate 10b, the two output member side plates 10a are arranged opposite to each other and are respectively bent and connected to the output member connecting plate 10b, the two output member side plates 10a are rotatably arranged on the mechanism bracket s, and the two first connecting rod side plates 11b are respectively located on both sides of the two output member side plates 10 and are rotatably connected through a first shaft 1011s. Further, the middle parts of the two output member side plates 10a are rotatably arranged on the mechanism bracket s, one end is rotatably arranged with the two first connecting rod side plates 11a around the first shaft 1011s, and the other end is used for transmission connection with the moving contact mechanism 200-1u (this end is used for connection with the linkage shaft 40, and the linkage shaft 40 drives the rotating disk 60 to rotate, and the rotating disk 60 drives the moving contact mechanism 200-1u to rotate). Furthermore, the two output member side plates 10a are both provided with output member shaft holes, and the two output member side plates 10a are sleeved on the driving shaft 1 of the driving shaft structure through the output member shaft holes, thereby realizing rotational installation on the mechanism bracket.

[0116] like Figure 6-8 shows a layout of the operating mechanism 100: an installation space is formed between the two side plates of the mechanism bracket s; the jumper 15, the main spring 16, the second connecting rod 12, the first connecting rod 11, the locking member 20, the re-fastening member 21, the output member 10 and the auxiliary spring 30 are all located in the installation space; in the first direction of the installation space, the two ends of the installation space are respectively the first end and the second end, the rocker arm cross beam 6-01 of the rocker arm 6 is located outside the first end of the installation space, and the output member 10 is located in the second end of the installation space; in the second direction of the installation space, the two ends of the installation space are respectively the third end and the fourth end, the locking member 20 and the re-fastening member 21 are located in the third end of the installation space, the auxiliary spring 30 is located in the fourth end of the installation space, and the jumper 15 extends from the third end to the fourth end; the first direction and the second direction are both parallel to the two side plates of the mechanism bracket s and the first direction and the second direction intersect. Furthermore, in the second direction of the installation space, the buffer 41 is arranged in the fourth end, and the output member 10 is located between the buffer 41 and the rocker beam 6-01 of the rocker arm 6; the jumper stop shaft 17 is arranged in the fourth end, and the jumper stop shaft 17 and the auxiliary spring 30 are located on both sides of the jumper 15 in the first direction of the installation space. The layout of the operating mechanism 100 is reasonable and compact, which is conducive to reducing the space. Specifically, the first direction is Figure 6 -8 left and right direction, the second direction is Figure 6 -8 up and down direction.
