Benefits of technology

[0007]In this application, the auxiliary device is mounted on the contact unit of the switch body and can be directly linked to the contact unit, rather than being mounted on the operating mechanism of the switch body. Since the separation and contact of the moving and stationary contacts in the contact unit directly reflects the opening and closing of the switch body, the action of the contact unit provides a more direct reflection of the opening and closing status of the switch body compared to the action of the operating mechanism. Therefore, mounting the auxiliary device on the contact unit provides more timely and accurate feedback on the opening and closing status of the switch body compared to mounting it on the operating mechanism, and the possibility of malfunction or delayed action of the auxiliary device is lower. Thus, the reliability of the auxiliary device's feedback on the opening and closing status of the switch body can be improved.

Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and more particularly to a disconnecting switch. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power sources, switching operations, and connecting and disconnecting current circuits, and it also has an arc-extinguishing function. In applications where disconnecting switches are used, auxiliary devices are typically provided to assist in providing feedback on the open / closed status of the switch body.

[0003] In related technologies, the reliability of auxiliary devices in providing feedback on the open / closed status of the switch body is relatively low. Furthermore, existing disconnect switches have fixed structures, limited applicability, and are prone to resource waste, making it difficult to meet user needs. Utility Model Content

[0004] This application provides a disconnecting switch that can improve the reliability of the auxiliary device feedback switch body when the switch body is in the open or closed state, and can also increase the application range of the disconnecting switch, reduce resource waste, and improve user satisfaction.

[0005] In a first aspect, this application provides a disconnecting switch, comprising: a switch body and an auxiliary device. The switch body includes a contact unit, the contact housing of the contact unit having a first mounting hole, the output shaft of the contact unit being rotatably mounted on the contact housing, and the output end of the output shaft being located within the first mounting hole. The auxiliary device includes an auxiliary terminal box, a turntable, and an auxiliary terminal, the auxiliary terminal box being detachably connected to the contact housing. The turntable includes a triggering part and a driven part, both the triggering part and the auxiliary terminal being located within the auxiliary terminal box, and the triggering part pressing against the auxiliary terminal. The auxiliary terminal box has a second mounting hole, the driven part passing through the second mounting hole and extending to the first mounting hole, for driving engagement with the output terminal within the first mounting hole.

[0006] When the output shaft rotates to perform the opening or closing operation of the switch body, the output terminal drives the rotary table to rotate through cooperation with the driven part. As the rotary table rotates, the triggering part triggers the auxiliary terminal to switch states through cooperation with the auxiliary terminal. The auxiliary terminal states include an on state and an off state, and the auxiliary terminal is used to provide feedback on the opening and closing status of the switch body.

[0007] In this application, the auxiliary device is mounted on the contact unit of the switch body and can be directly linked to the contact unit, rather than being mounted on the operating mechanism of the switch body. Since the separation and contact of the moving and stationary contacts in the contact unit directly reflects the opening and closing of the switch body, the action of the contact unit provides a more direct reflection of the opening and closing status of the switch body compared to the action of the operating mechanism. Therefore, mounting the auxiliary device on the contact unit provides more timely and accurate feedback on the opening and closing status of the switch body compared to mounting it on the operating mechanism, and the possibility of malfunction or delayed action of the auxiliary device is lower. Thus, the reliability of the auxiliary device's feedback on the opening and closing status of the switch body can be improved.

[0008] Furthermore, the auxiliary terminal box is detachably connected to the contact housing, allowing for easy removal and installation of auxiliary devices from or onto the switch body. This enables users to freely remove existing auxiliary devices and install new ones that meet their needs. Consequently, the structure of the disconnecting switch is adjustable, increasing its applicability, reducing the likelihood of switches being scrapped due to incompatibility, minimizing resource waste, and improving user satisfaction.

[0009] In one possible design, the auxiliary terminal box includes a terminal base and a terminal cover that overlap each other, with the trigger portion and auxiliary terminal located within the space enclosed by the terminal base and the terminal cover. The terminal base is closer to the contact housing than the terminal cover, and the terminal base has a first connecting structure, while the contact housing has a second connecting structure, with the first connecting structure cooperating with the second connecting structure.

[0010] With the above design, the trigger and auxiliary terminal are located within the space enclosed by the terminal base and terminal cover. This facilitates the trigger's ability to press or release the auxiliary terminal during turntable rotation, switching the auxiliary terminal's state. Furthermore, the terminal base and terminal cover protect the trigger and auxiliary terminal, reducing the possibility of damage to the auxiliary terminal from rain or other sources, and minimizing the possibility of impurities falling between the trigger and auxiliary terminal, which could reduce the reliability of their pressing connection. Additionally, the combination of the first and second connecting structures allows the terminal base to be detachably connected to the contact housing, facilitating connection and disassembly between the terminal base and the contact housing.

[0011] In one possible design, one of the sides of the contact housing facing the terminal block and the other of the side of the terminal block facing the contact housing is provided with a positioning post, and the positioning post and the positioning hole are provided with a positioning hole, with the positioning post and the positioning hole cooperating.

[0012] With the above solution, when the terminal block is connected to the contact housing, the cooperation of the positioning post and the positioning hole can provide guidance and positioning for the terminal block, making it easy for the terminal block to be quickly aligned with the appropriate position of the contact housing. This makes it easy for the driven part to accurately extend into the first mounting hole and cooperate with the output end after passing through the second mounting hole.

[0013] In one possible design, a positioning rod is provided on the side of the terminal block facing the terminal cover, and an auxiliary terminal is sleeved on the positioning rod. A limiting member is also provided on the side of the terminal block facing the terminal cover, and the limiting member abuts against the adjacent two sides of the auxiliary terminal.

[0014] With the above solution, the auxiliary terminal is sleeved onto the positioning rod, allowing it to be placed in a suitable position within the auxiliary terminal box. The limiting component can limit the auxiliary terminal in two directions, reducing the possibility of displacement within the auxiliary terminal box and thus improving the reliability of the mating relationship between the auxiliary terminal and the trigger unit.

[0015] In one possible design, there are multiple limiting members corresponding to one auxiliary terminal, and two limiting members are arranged along the diagonal of the auxiliary terminal.

[0016] Through the above scheme, an auxiliary terminal can be limited by multiple limiting members, improving the limiting effect of the limiting members on the auxiliary terminal. Furthermore, since each limiting member abuts against the adjacent two sides of the auxiliary terminal, two limiting members are arranged diagonally along the auxiliary terminal among the multiple limiting members corresponding to one auxiliary terminal. These two limiting members can abut against four different sides of the auxiliary terminal. In this way, the auxiliary terminal can be limited in at least four directions, further reducing the possibility of movement of the auxiliary terminal within the auxiliary terminal box.

[0017] In one possible design, the turntable further includes a connecting portion located within an auxiliary terminal box. A driven portion is connected to the side of the connecting portion facing the contact housing, and a trigger portion is connected to the peripheral sidewall of the connecting portion.

[0018] The above solution allows the driven part and the triggering part to be connected as a whole through the connecting part, which facilitates the installation of the turntable in the auxiliary terminal box.

[0019] In one possible design, the turntable further includes a thickened portion connected to the side of the connecting portion facing the terminal cover. One side of the thickened portion facing the terminal cover and the other side of the terminal cover facing the thickened portion have a protrusion, and the other has a recess, with the protrusion and recess fitting together.

[0020] The thickened portion is connected to the side of the connecting portion facing the terminal cover, which increases the size of the turntable within the auxiliary terminal box along the thickness direction of the connecting portion. This facilitates the clamping of the connecting portion and the thickened portion between the terminal cover and the terminal seat in the thickness direction of the connecting portion, thereby reducing the possibility of displacement of the turntable in the thickness direction of the connecting portion. The cooperation between the protruding post and the recessed hole further reduces the possibility of radial displacement of the turntable relative to the terminal cover in the connecting portion during rotation, thus improving the stability and reliability of the turntable during rotation.

[0021] In one possible design, the terminal cover has a raised rib on the side facing the thickened portion. The connecting portion abuts against the inner wall of the auxiliary terminal box on the side facing the contact housing, and the thickened portion abuts against the raised rib.

[0022] The connecting part abuts against the inner wall of the auxiliary terminal box on the side facing the contact housing, that is, the connecting part abuts against the side of the terminal block away from the switch body. In this configuration, the side of the terminal block away from the switch body can limit the connection part, which helps to reduce the possibility of the turntable moving towards the switch body after it is installed in the auxiliary terminal box, thereby improving the positional stability of the turntable in the auxiliary terminal box.

[0023] The thickened part abuts against the raised rib, which can limit the thickened part, making it easier to reduce the possibility of the turntable moving away from the switch body after it is installed in the auxiliary terminal box, and also to improve the positional stability of the turntable in the auxiliary terminal box.

[0024] In one possible design, the connecting part is a circular plate structure, and the terminal cover has an arc-shaped plate on the side facing the contact shell. The arc-shaped plate cooperates with the remaining positions on the peripheral wall of the connecting part, except for the position where the trigger part is located.

[0025] With the above solution, when the turntable rotates relative to the auxiliary terminal box, the connecting part rotates relative to the arc-shaped plate along the path defined by the arc-shaped plate. In this way, the arc-shaped plate can limit the rotation of the turntable, improving the stability and reliability of the turntable's rotation.

[0026] In one possible design, the edge of the terminal block is provided with a connecting post, and the terminal cover is provided with a connecting hole at a position opposite to the connecting post. The connecting post extends into the connecting hole and is connected to the connecting hole.

[0027] The connection between the connecting post and the connecting hole not only provides guidance and positioning for the installation of the terminal cover onto the terminal block, facilitating quick and proper alignment of the terminal cover with the terminal block, but also enables a fixed connection between the terminal cover and the terminal block. This simple connection method is highly operable and improves assembly efficiency. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0043] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0048] Disconnecting switches are mainly used for isolating power supplies, switching operations, and connecting and disconnecting current circuits. Existing disconnecting switches, in addition to the switch body itself, also include auxiliary devices to provide feedback on the open / closed status of the switch body.

[0049] In related technologies, auxiliary devices are generally mounted on the operating mechanism of the switch body, and the auxiliary device is driven by the actuating element in the operating mechanism to realize the feedback function of the auxiliary device.

[0050] However, when the operating mechanism actuates, it requires the cooperation of structural components such as a rotating shaft to transmit the driving force to the moving contact of the switch body. This causes the moving contact to rotate when the operating mechanism actuates, making contact with or separating from the stationary contact of the switch body, thus closing or opening the switch. Therefore, multiple stages of transmission are required between the operating mechanism and the moving contact. An abnormality in any stage of this transmission will cause inconsistencies between the operation of the operating mechanism and the movement of the moving contact. Consequently, when the auxiliary device is driven by the operating mechanism, the auxiliary device may not be able to provide timely and accurate feedback on the switch body's closing or opening status; in other words, the auxiliary device may malfunction or be slow to act. Therefore, the reliability of the auxiliary device in providing feedback on the switch body's closing or opening status is low.

[0051] In addition, there are two types of disconnect switches in related technologies. The first type has an auxiliary device, and the second type does not. For disconnect switches with auxiliary devices, the auxiliary device is pre-installed on the switch body at the factory and cannot be removed by the user. For disconnect switches without auxiliary devices, the user cannot install the auxiliary device due to reasons such as the lack of pre-reserved installation positions at the factory.

[0052] If a user buys a disconnect switch without auxiliary devices but later requires them, they will need to purchase a new disconnect switch with auxiliary devices. Similarly, if a user buys a disconnect switch with auxiliary devices but later has different needs for those devices, they will also need to purchase a new disconnect switch that meets their requirements. It is evident that the structure of disconnect switches is relatively fixed; the structure at the time of manufacture dictates its usability, resulting in a narrow scope of application and undoubtedly leading to resource waste and low user satisfaction.

[0053] In view of this, this application provides a disconnecting switch to improve the reliability of the auxiliary device feedback switch body when it is in the open or closed state, increase the applicability of the disconnecting switch, reduce resource waste, and improve user satisfaction.

[0054] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0055] Figure 1 This is a schematic diagram of a combination structure of a disconnecting switch provided in an embodiment of this application, as shown below. Figure 1 As shown, the disconnecting switch includes a switch body 1 and an auxiliary device 2.

[0056] The switch body 1 is the main structure of the disconnecting switch. The disconnecting switch realizes its functions of isolating power supply, switching, connecting and disconnecting current circuits through the switch body 1. The auxiliary device 2 can be a micro switch, limit switch, etc.

[0057] Figure 2 This is an exploded view of a disconnecting switch provided in an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, the switch body 1 includes a contact unit 10. The contact housing 100 of the contact unit 10 is provided with a first mounting hole. The output shaft 101 of the contact unit 10 is rotatably mounted on the contact housing 100, and the output end of the output shaft 101 is located in the first mounting hole.

[0058] The switch body 1 includes an operating mechanism 11 and contact units 10. The number of contact units 10 can be one or more. Figure 2 The number of contact units 10 shown is two, with one contact unit 10 on each of the opposite sides of the operating mechanism 11.

[0059] The operating mechanism 11 includes an operating shaft 110, and the contact unit 10 includes an output shaft 101. The output shaft 101 includes an input end and an output end. The operating shaft 110 is linked to the input end of the output shaft 101 via other intermediate structural components. Through the operating shaft 110 and other intermediate structural components, the operating mechanism 11 can transmit driving force to the output end of the output shaft 101. Thus, when the operating shaft 110 rotates, it can drive the output shaft 101 to rotate. The specific linkage relationship between the operating mechanism 11 and the contact unit 10 can be found in relevant technologies and will not be elaborated here.

[0060] The contact unit 10 also includes at least one set of moving contacts and stationary contacts. The output shaft 101 in the contact unit 10 acts as a contact support, and the moving contact is fixedly mounted on the output shaft 101, thus allowing the moving contact to rotate with the output shaft 101. When the moving contact rotates to contact the stationary contact, the switch body 1 closes. When the moving contact rotates to separate from the stationary contact, the switch body 1 opens.

[0061] The contact unit 10 also includes a contact housing 100, which has a first receiving space in which the moving contact and the stationary contact are installed. An output shaft 101 is rotatably connected to the contact housing 100, thus allowing the output shaft 101 to rotate relative to the contact housing 100. The contact housing 100 has a first mounting hole on the side facing the auxiliary device 2, with the input end of the output shaft 101 located within the first receiving space and the output end of the output shaft 101 located within the first mounting hole.

[0062] like Figure 1 and Figure 2 As shown, the auxiliary device is located on the side of the contact housing 100 away from the operating mechanism 11. Figure 3 This is a schematic diagram of the structure of an auxiliary device provided in an embodiment of this application from one viewpoint. Figure 4 This is a schematic diagram of the structure of an auxiliary device provided in an embodiment of this application from another perspective. Figure 5 This is an exploded view of an auxiliary device provided in an embodiment of this application. Figure 6 This is a schematic diagram of the mating structure of the turntable and auxiliary terminals provided in an embodiment of this application, as shown below. Figures 1 to 6 As shown, the auxiliary device 2 includes an auxiliary terminal box 20, a turntable 21, and an auxiliary terminal 22. The auxiliary terminal box 20 is detachably connected to the contact housing 100. The turntable 21 includes a triggering part 210 and a driven part 211. Both the triggering part 210 and the auxiliary terminal 22 are located inside the auxiliary terminal box 20, and the triggering part 210 and the auxiliary terminal 22 are press-fitted. The auxiliary terminal box 20 is provided with a second mounting hole 2001. The driven part 211 passes through the second mounting hole 2001 and extends to the first mounting hole to drive and engage with the output terminal in the first mounting hole.

[0063] The auxiliary terminal box 20 can be detachably connected to the contact housing 100 by any means such as plugging, snapping, or screwing.

[0064] The auxiliary terminal box 20 has a second receiving space in which the auxiliary terminal 22 is installed. The portion of the turntable 21 that mates with the auxiliary terminal 22 is defined as the trigger portion 210, and the portion of the turntable 21 that mates with the output shaft 101 is defined as the driven portion 211. The trigger portion 210 is located within the second receiving space to press or release the auxiliary terminal 22. The auxiliary terminal box 20 has a second mounting hole 2001 on the side facing the switch body 1, and the driven portion 211 extends from the second mounting hole 2001 to a first mounting hole to drive the output terminal within the first mounting hole.

[0065] For example, combined Figure 1 , Figure 2 and Figure 6 The output end is provided with an irregular notch 1011. The shape of the driven part 211 is consistent with the shape of the notch 1011. The driven part 211 is precisely embedded in the notch 1011, realizing the driving cooperation between the driven part 211 and the output end.

[0066] The working principle of the disconnecting switch body 1 and auxiliary device 2 provided in this application is as follows: When the operating shaft 110 in the operating mechanism 11 is driven to rotate, it drives the output shaft 101 in the contact unit 10 to rotate. When the output shaft 101 rotates, it performs the opening or closing operation of the switch body 1. At the same time, the output end of the output shaft 101 drives the turntable 21 to rotate through cooperation with the driven part 211. When the turntable 21 rotates, the triggering part 210 triggers the auxiliary terminal 22 to switch states through cooperation with the auxiliary terminal 22. The states of the auxiliary terminal 22 include an on state and an off state. The auxiliary terminal 22 is used to provide feedback on the opening and closing states of the switch body 1.

[0067] The operating shaft 110 is basically perpendicular to the output shaft 101. The axis of the output shaft 101 is collinear with the central axis of the turntable 21. In this way, the rotation direction of the output shaft 101 is consistent with the rotation direction of the turntable 21. The operating shaft 110 can reliably transmit the driving force to the turntable 21 through the output shaft 101.

[0068] For example, assuming the output shaft 101 rotates in the first direction and the switch body 1 is closed, then the output drive disc 21 also rotates in the first direction. When the disc 21 rotates in the first direction, the trigger unit 210 triggers the auxiliary terminal 22 in the first state. Conversely, assuming the output shaft 101 rotates in the second direction and the switch body 1 is open, then the output shaft 101 drives the disc 21 to rotate in the second direction. When the disc 21 rotates in the second direction, the trigger unit 210 triggers the auxiliary terminal 22 in the second state.

[0069] In this configuration, one of the first direction and the second direction is clockwise, and the other is counterclockwise. One of the first state and the second state is an on state, and the other is an off state.

[0070] When the first direction corresponds to one of the closed or open states of the switch body 1, the second direction corresponds to the other of the closed or open states. This embodiment does not limit the correspondence between the rotation direction of the output shaft 101 and the closed / open states of the switch body 1, as long as the switch body 1 can switch from one state to another when the output shaft 101 rotates in different directions.

[0071] When the first direction corresponds to one of the on or off states, the second direction corresponds to the other of the on or off states. For example, assuming the auxiliary terminal 22 is in the on state when the turntable 21 rotates in the first direction, then the auxiliary terminal 22 is in the off state when the turntable 21 rotates in the second direction. Furthermore, assuming the auxiliary terminal 22 is in the off state when the turntable 21 rotates in the first direction, then the auxiliary terminal 22 is in the on state when the turntable 21 rotates in the second direction.

[0072] In this embodiment, the correspondence between the rotation direction of the shaft and the state of the auxiliary terminal 22 is not limited. As long as the shaft rotates in different directions, the state of the auxiliary terminal 22 can be switched from one state to another.

[0073] The auxiliary terminal 22 has two states: one is in the ON state, which corresponds to the switch body 1 being in the open state, and the other is in the OFF state, which corresponds to the switch body 1 being in the OFF state. For example, suppose that when the auxiliary terminal 22 is in the ON state, the feedback switch body 1 is in the OFF state. Then, when the auxiliary terminal 22 is in the OFF state, the feedback switch body 1 is in the OFF state. Alternatively, suppose that when the auxiliary terminal 22 is in the OFF state, the feedback switch body 1 is in the OFF state. Then, when the auxiliary terminal 22 is in the ON state, the feedback switch body 1 is in the OFF state.

[0074] It should be noted that when the trigger part 210 presses the auxiliary terminal 22, the auxiliary terminal 22 can be in a connected state. When the trigger part 210 releases the pressure on the auxiliary terminal 22, the auxiliary terminal 22 can be in a disconnected state. The trigger part 210 can be a plate-shaped or columnar structure.

[0075] In the disconnect switch provided in this application embodiment, the auxiliary terminal box 20 of the auxiliary device 2 is connected to the contact shell 100 of the contact unit 10 in the switch body 1. The driven part 211 of the turntable 21 in the auxiliary device 2 drives and engages with the output shaft 101 of the contact unit 10 in the switch body 1 within the first mounting hole. When the output shaft 101 rotates, the output end drives the turntable 21 to rotate through its engagement with the driven part 211. Therefore, in this application, the auxiliary device 2 is mounted on the contact unit 10 of the switch body 1 and can be directly linked with the contact unit 10, rather than being mounted on the operating mechanism 11 of the switch body 1.

[0076] Since the separation and contact of the moving and stationary contacts in the contact unit 10 directly reflects the opening and closing status of the switch body 1, the action of the contact unit 10 can more directly reflect the opening and closing status of the switch body 1 than the action of the operating mechanism 11. Therefore, the auxiliary device 2, mounted on the contact unit 10, can provide more timely and accurate feedback on the opening and closing status of the switch body 1 than if mounted on the operating mechanism 11. The possibility of the auxiliary device 2 malfunctioning or not acting in a timely manner is also lower. Therefore, the reliability of the auxiliary device 2 in feedback on the opening and closing status of the switch body 1 can be improved.

[0077] Furthermore, the auxiliary terminal box 20 is detachably connected to the contact housing 100, allowing the auxiliary device 2 to be easily removed from the switch body 1 and easily installed on the switch body 1. Based on this, if a user has new requirements for the existing auxiliary device 2, such as wanting to increase the number of auxiliary terminals 22 within the auxiliary device 2, the user can freely remove the existing auxiliary device 2 from the switch body 1 and install the new auxiliary device 2 that meets their needs on the switch body 1. This makes the structure of the disconnecting switch adjustable, increasing its applicability, reducing the possibility of the disconnecting switch being scrapped due to not meeting user needs, reducing resource waste, and improving user satisfaction.

[0078] The auxiliary device 2 of this application can accommodate 1 to 4 auxiliary terminals 22. Users can select the number of auxiliary terminals 22 according to their needs and can install the auxiliary device 2 onto the contact housing 100 themselves. The number of trigger units 210 can be set according to the number of auxiliary terminals 22.

[0079] For example, when the number of auxiliary terminals 22 is 1, the number of trigger units 210 is set to 1 accordingly.

[0080] When the number of auxiliary terminals 22 is 2, assuming the two auxiliary terminals 22 are arranged close to the same side of the auxiliary terminal box 20 and the trigger buttons of the two auxiliary terminals 22 face each other, then the number of trigger parts 210 can be set to 1, and the trigger part 210 is located between the two auxiliary terminals 22. When the number of auxiliary terminals 22 is 2, assuming the two auxiliary terminals 22 are arranged close to the same side of the auxiliary terminal box 20, but the trigger buttons of the two auxiliary terminals 22 face the same direction, then the number of trigger parts 210 can be set to 2, and the two trigger parts 210 correspond one-to-one with the two auxiliary terminals 22.

[0081] When the number of auxiliary terminals 22 is 3, the number of trigger units 210 can be set to 2. Two diagonally distributed auxiliary terminals 22 correspond to the same trigger unit 210, and these two auxiliary terminals 22 provide feedback on one state of the switch body 1. The other auxiliary terminal 22 corresponds to another trigger unit 210 and provides feedback on the other state of the switch body 1.

[0082] When the number of auxiliary terminals 22 is 4, such as Figure 6 As shown, the number of trigger units 210 can be set to 2, wherein every two diagonally distributed auxiliary terminals 22 correspond to the same trigger unit 210, the two diagonally distributed auxiliary terminals 22 provide feedback on one state of the switch body 1, and the other two diagonally distributed auxiliary terminals 22 provide feedback on another state of the switch body 1.

[0083] When the two auxiliary terminals 22 provide feedback on the state of the switch body 1, even if one auxiliary terminal 22 fails, the other auxiliary terminal 22 can still provide normal feedback on the state of the switch body 1. This improves the reliability of the auxiliary device 2's feedback on the open / closed state of the switch body 1.

[0084] Based on the disconnecting switch provided in the above embodiments, please continue to refer to... Figures 2 to 6 ,like Figures 2 to 6 As shown, the auxiliary terminal box 20 includes a terminal base 200 and a terminal cover 201 that overlap each other. The trigger part 210 and the auxiliary terminal 22 are located within the space enclosed by the terminal base 200 and the terminal cover 201. The terminal base 200 is closer to the contact housing 100 than the terminal cover 201. The terminal base 200 is provided with a first connecting structure 2002, and the contact housing 100 is provided with a second connecting structure 102. The first connecting structure 2002 and the second connecting structure 102 cooperate with each other.

[0085] Terminal block 200 and terminal cover 201 can be connected by plug-in, snap-in, screw connection or other methods. Figure 7 This is a schematic diagram of the terminal block provided in an embodiment of this application from one viewpoint. Figure 8 This is a schematic diagram of the terminal cover provided in an embodiment of this application, exemplarily. Figure 7 and Figure 8 The terminal block 200 and terminal cover 201 are shown. The edge of the terminal block 200 is provided with a connecting post 2003. The terminal cover 201 is provided with a connecting hole 2010 at a position opposite to the connecting post 2003. The connecting post 2003 extends into the connecting hole 2010 and is connected to the connecting hole 2010.

[0086] like Figure 7 As shown, the terminal block 200 includes four flanges, and the edges of the terminal block 200 are where the four flanges are located. Multiple connecting posts 2003 are spaced apart on each of the four flanges. Figure 8 As shown, the terminal cover 201 is flat, and its edge is provided with multiple connection holes 2010. Multiple connecting posts 2003 correspond one-to-one with the multiple connection holes 2010. Each connecting post 2003 extends into and connects to its corresponding connection hole 2010, thus connecting the terminal base 200 to the terminal cover 201. The multiple connecting posts 2003 and their corresponding connection holes 2010 can be connected by thermal riveting.

[0087] Based on the foregoing description, the auxiliary terminal box 20 can be detachably connected to the contact housing 100 by any method, such as plug-in, snap-in, or screw connection. Assuming the auxiliary terminal box 20 is connected to the contact housing 100 by plug-in, one of the first connecting structure 2002 and the second connecting structure 102 can be a plug strip, and the other can be a slot. Inserting the plug strip into the slot and connecting it to the slot allows the auxiliary terminal box 20 to be plugged into the contact housing 100. Assuming the auxiliary terminal box 20 is connected to the contact housing 100 by snap-in, one of the first connecting structure 2002 and the second connecting structure 102 can be a slot, and the other can be a snap-fit. The snap-fit ​​engages with the slot, allowing the auxiliary terminal box 20 to be snapped into the contact housing 100.

[0088] Please refer to Figures 1 to 4 Assuming the auxiliary terminal box 20 is connected to the contact housing 100 by screws, then... Figures 1 to 4 ,as well as Figure 7 As shown, the auxiliary terminal box 20 may have multiple connecting ears 202 spaced apart on the side near the contact housing 100. Each connecting ear 202 has a first connecting hole, and the contact housing 100 has a second connecting hole at a position opposite to the first connecting hole. The end of a screw passes through the first connecting hole and connects to the corresponding second connecting hole, thereby screwing the auxiliary terminal box 20 to the contact housing 100. The first connecting structure 2002 is the first connecting hole, and the second connecting structure 102 is the second connecting hole. The screw can be a flat-head screw.

[0089] Figures 1 to 3The auxiliary terminal box 20 is equipped with four screws. After the auxiliary terminal box 20 is aligned with the contact housing 100, only four screws need to be tightened to assemble the auxiliary terminal box 20 on the contact housing 100. The assembly is simple and highly operable.

[0090] Regardless of the specific structural form of the first connection structure 2002 and the second connection structure 102, when the auxiliary terminal box 20 is connected to the contact shell 100, the terminal block 200 can fit against the contact shell 100, which can improve the connection reliability between the auxiliary terminal box 20 and the contact shell 100.

[0091] In this embodiment, the trigger part 210 and the auxiliary terminal 22 are located within the space enclosed by the terminal base 200 and the terminal cover 201. This facilitates the trigger part 210 pressing or releasing the auxiliary terminal 22 when the turntable 21 rotates, thereby switching the state of the auxiliary terminal 22. Furthermore, the trigger part 210 and the auxiliary terminal 22 can be covered by the terminal base 200 and the terminal cover 201, reducing the possibility of damage to the auxiliary terminal 22 due to rain or other factors, and also reducing the possibility of impurities falling between the trigger part 210 and the auxiliary terminal 22, which could reduce the reliability of the pressing fit. Additionally, through the cooperation of the first connecting structure 2002 and the second connecting structure 102, the terminal base 200 can be detachably connected to the contact housing 100, facilitating the connection and disconnection of the terminal base 200 and the contact housing 100.

[0092] Based on the disconnect switch provided in the above embodiment, since the driven part 211 of the turntable 21 needs to pass through the second mounting hole 2001 and extend to the first mounting hole to drive and cooperate with the output end of the output shaft 101 in the first mounting hole, and the output shaft 101 needs to transmit the driving force to the turntable 21 through the driving cooperation between the output shaft 101 and the driven part 211, the first mounting hole and the second mounting hole 2001 need to be set at opposite ends so that the driven part 211 can extend into the first mounting hole and cooperate with the output end after passing through the second mounting hole 2001.

[0093] In view of this, such as Figure 2 , Figure 4 and Figure 9 As shown, one of the sides of the contact housing 100 facing the terminal block 200 and the other of the side of the terminal block 200 facing the contact housing 100 may be provided with a positioning post 2004 and a positioning hole 103, with the positioning post 2004 cooperating with the positioning hole 103.

[0094] With this configuration, when the terminal block 200 is connected to the contact housing 100, the cooperation between the positioning post 2004 and the positioning hole 103 can provide guidance and positioning for the terminal block 200, making it easy for the terminal block 200 to quickly align with the appropriate position of the contact housing 100. This allows the driven part 211 to accurately extend into the first mounting hole and cooperate with the output end after passing through the second mounting hole 2001.

[0095] The number of positioning pins 2004 and positioning holes 103 can be one or more. When there are multiple positioning pins 2004 and positioning holes 103, the multiple positioning pins 2004 and multiple positioning holes 103 can be arranged at intervals. Regardless of whether there is one or more positioning pins 2004 and positioning holes 103, the positioning pins 2004 and positioning holes 103 have a one-to-one correspondence, and each positioning pin 2004 can extend into the corresponding positioning hole 103.

[0096] The contact housing 100 is a component of the switch body 1, and the terminal block 200 is a component of the auxiliary device 2. Generally, the volume of the switch body 1 is larger than that of the auxiliary device 2. Therefore, when the two are connected, the auxiliary device 2 is usually moved to a suitable position towards the switch body 1 before connection. Based on this, the positioning post 2004 can be located on the side of the terminal block 200 facing the contact housing 100, and the positioning hole 103 can be located on the side of the contact housing 100 facing the terminal block 200. In this way, when the auxiliary device 2 moves towards the switch body 1, it is easier to observe the relative position of the positioning post 2004 and the positioning hole 103, and it is easier to move the auxiliary device 2 to a suitable position relative to the switch body 1, thereby improving the efficiency of installing the auxiliary device 2 onto the switch body 1.

[0097] The following describes the installation and fixation of the auxiliary terminal 22 in the auxiliary terminal box 20 with reference to the accompanying drawings.

[0098] like Figure 4 , Figure 5 and Figure 7 As shown, a positioning rod 2005 is provided on the side of the terminal block 200 facing the terminal cover 201, and the auxiliary terminal 22 is sleeved on the positioning rod 2005.

[0099] Taking the auxiliary device 2 as a micro switch as an example, each micro switch has two mounting holes. Correspondingly, there can also be two positioning rods 2005 on the side of the terminal block 200 facing the terminal cover 201. The micro switch is fitted onto the corresponding positioning rod 2005 through the two holes, thus placing the micro switch in a suitable position inside the auxiliary terminal box 20.

[0100] In addition, such as Figure 4 , Figure 5 and Figure 7As shown, the terminal block 200 is also provided with a limiting member 2006 on the side facing the terminal cover 201, and the limiting member 2006 abuts against the adjacent two sides of the auxiliary terminal 22.

[0101] Specifically, the limiting member 2006 includes an adjacent first limiting surface and a second limiting surface, which are substantially perpendicular. When the auxiliary terminal 22 is installed in place, the first limiting surface contacts the first side surface of the auxiliary terminal 22, and the second limiting surface contacts the second side surface of the auxiliary terminal 22. The first and second sides of the auxiliary terminal 22 are adjacent sides of the auxiliary terminal 22.

[0102] With this configuration, the limiting member 2006 can limit the auxiliary terminal 22 in two directions, reducing the possibility of the auxiliary terminal 22 moving within the auxiliary terminal box 20, thereby improving the reliability of the cooperation between the auxiliary terminal 22 and the trigger part 210.

[0103] The number of limiting members 2006 corresponding to one auxiliary terminal 22 can be one or more.

[0104] When there are multiple limiting members 2006, the multiple limiting members 2006 can be spaced apart around the auxiliary terminal 22. For example, corresponding to one auxiliary terminal 22, there are multiple limiting members 2006, and two limiting members 2006 are arranged along the diagonal of the auxiliary terminal 22.

[0105] With this configuration, an auxiliary terminal 22 can be limited by multiple limiting members 2006, improving the limiting effect of the limiting members 2006 on the auxiliary terminal 22. Furthermore, since each limiting member 2006 abuts against the adjacent two sides of the auxiliary terminal 22, two limiting members 2006 are arranged diagonally along the auxiliary terminal 22 among the multiple limiting members 2006 corresponding to one auxiliary terminal 22. These two limiting members 2006 can abut against four different sides of the auxiliary terminal 22. In this way, the auxiliary terminal 22 can be limited in at least four directions, further reducing the possibility of movement of the auxiliary terminal 22 within the auxiliary terminal box 20.

[0106] When the auxiliary terminal 22 is a cuboid micro switch as shown in the figure, the auxiliary terminal 22 has four different sides. In this case, the number of limiting members 2006 corresponding to one auxiliary terminal 22 can be four. Two of the limiting members 2006 are arranged along one diagonal of the auxiliary terminal 22, and the other two limiting members 2006 are arranged along the other diagonal of the auxiliary terminal 22.

[0107] When the auxiliary terminal 22 has other structural forms, the maximum number of limiting members 2006 can be set according to the specific shape of the auxiliary terminal 22, and this application does not limit this.

[0108] Next, the specific structure of the turntable 21 and its installation in the auxiliary terminal box 20 will be explained with reference to the attached drawings.

[0109] Figure 10 This is a schematic diagram of the turntable provided in an embodiment of this application from one perspective. Figure 11 This is a schematic diagram of the turntable provided in the embodiment of this application from another perspective, combined with... Figures 2 to 4 ,as well as Figure 10 and Figure 11 In addition to the triggering part 210 and the driven part 211 mentioned above, the turntable 21 also includes a connecting part 212. The connecting part 212 is located inside the auxiliary terminal box 20. The driven part 211 is connected to the side of the connecting part 212 facing the contact housing 100, and the triggering part 210 is connected to the peripheral sidewall of the connecting part 212.

[0110] The driven part 211 and the triggering part 210 can be integrally formed on the connecting part 212 to save assembly steps for each part of the turntable 21.

[0111] The connecting part 212 can be a circular plate structure, so that the turntable 21 is less likely to interfere with other structural components when it rotates with the output shaft 101.

[0112] The radial dimension of the connecting portion 212 can be slightly larger than the diameter of the second mounting hole 2001, so that when the turntable 21 is installed from the side of the terminal block 200 away from the switch body 1 to the auxiliary terminal box 20, the connecting portion 212 can abut against the side of the terminal block 200 away from the switch body 1. In this way, the side of the terminal block 200 away from the switch body 1 can limit the connecting portion 212, which helps to reduce the possibility of the turntable 21 moving towards the switch body 1 after it is installed in the auxiliary terminal box 20, thereby improving the positional stability of the turntable 21 within the auxiliary terminal box 20.

[0113] When the connecting part 212 has a circular plate-like structure, its peripheral sidewall is the part with the largest rotation angle when it rotates. Therefore, the trigger part 210 is connected to the peripheral sidewall of the connecting part 212, and the connecting part 212 can drive the trigger part 210 to rotate at a large angle with only a small rotation angle. When the required rotation angle of the trigger part 210 is constant, this arrangement helps to save the driving force required for the rotation of the turntable 21. When the driving force for rotating the turntable 21 is constant, this arrangement helps to reduce the rotation angle of the trigger part 210, thereby saving the space occupied by the trigger part 210 when it rotates.

[0114] Please continue to refer to Figure 4 and Figure 11 Based on the disconnecting switch provided in the above embodiments, such as Figure 4 and Figure 11 As shown, the turntable 21 also includes a thickened portion 213, which is connected to the side of the connecting portion 212 facing the terminal cover 201.

[0115] The thickening portion 213 can be any shape, such as a circular plate or a square plate. The thickening portion 213 can be integrally formed on or detachably connected to the side of the connecting portion 212 facing the terminal cover 201. In the radial direction of the connecting portion 212, the size of the thickening portion 213 can be smaller than the size of the connecting portion 212, so as to save the amount of material used in the turntable 21 while still adjusting the size in the aforementioned thickness direction.

[0116] The thickened portion 213 is connected to the side of the connecting portion 212 facing the terminal cover 201, which can increase the size of the turntable 21 in the auxiliary terminal box 20 along the thickness direction of the connecting portion 212. This makes it easier for the connecting portion 212 and the thickened portion 213 to be sandwiched between the terminal cover 201 and the terminal seat 200 in the thickness direction of the connecting portion 212, thereby reducing the possibility of displacement of the turntable 21 in the thickness direction of the connecting portion 212.

[0117] like Figure 8 and Figure 11 As shown, one of the thickened portion 213 facing the terminal cover 201 and the other of the terminal cover 201 facing the thickened portion 213 has a protrusion 2011 and a recess 2131, and the protrusion 2011 and the recess 2131 are adapted to each other.

[0118] The end of the protruding post 2011 that is used to extend into the recessed hole 2131 may be provided with a rounded chamfer to reduce the difficulty of the protruding post 2011 extending into the recessed hole 2131.

[0119] When the turntable 21 is installed in place and the terminal cover 201 is installed onto the terminal base 200, the cooperation between the protrusion 2011 and the concave hole 2131 can provide guidance for the terminal cover 201 and the terminal base 200, making it easier for the terminal cover 201 and the terminal base 200 to be aligned and installed, thus improving the installation efficiency of the terminal cover 201 and the terminal base 200.

[0120] After the protrusion 2011 extends into the recess 2131, the side wall of the protrusion 2011 can contact the wall of the recess 2131. In this way, through the cooperation between the protrusion 2011 and the recess 2131, the possibility of displacement of the turntable 21 relative to the terminal cover 201 in the radial direction of the connection part 212 can be reduced, which helps to improve the stability and reliability of the turntable 21 during rotation.

[0121] The recess 2131 can be a blind hole, and the length of the protrusion 2011 can be slightly greater than the depth of the recess 2131. In this way, when the terminal cover 201 and the terminal base 200 are installed in place, the end of the protrusion 2011 can abut against the bottom wall of the recess 2131, so that the thickened portion 213 and the connecting portion 212 are pressed tightly between the terminal cover 201 and the terminal base 200 in the thickness direction of the connecting portion 212, further reducing the possibility of displacement of the turntable 21 in the thickness direction of the connecting portion 212.

[0122] Based on the disconnecting switch provided in the above embodiments, such as Figure 2 , Figure 8 and Figure 11 As shown, the terminal cover 201 may have a raised rib 2012 on the side facing the thickened portion 213. The side of the connecting portion 212 facing the contact housing 100 abuts against the inner wall of the auxiliary terminal box 20, and the thickened portion 213 abuts against the raised rib 2012.

[0123] The number of ribs 2012 can be one or more, and the ribs 2012 are provided in the terminal cover 201 at a position opposite to the thickened portion 213.

[0124] The side of the connecting portion 212 facing the contact housing 100 abuts against the inner wall of the auxiliary terminal box 20, that is, the connecting portion 212 abuts against the side of the terminal block 200 away from the switch body 1. With this arrangement, the side of the terminal block 200 away from the switch body 1 can limit the connecting portion 212, which helps to reduce the possibility of the turntable 21 moving towards the switch body 1 after it is installed in the auxiliary terminal box 20, thereby improving the positional stability of the turntable 21 within the auxiliary terminal box 20.

[0125] The thickened portion 213 abuts against the protruding rib 2012. The protruding rib 2012 can limit the thickened portion 213, which helps to reduce the possibility of the turntable 21 moving away from the switch body 1 after it is installed in the auxiliary terminal box 20, and also helps to improve the positional stability of the turntable 21 in the auxiliary terminal box 20.

[0126] Based on the above description, while the connecting part 212 abuts against the inner wall of the auxiliary terminal box 20 on the side facing the contact housing 100, the thickened part 213 also abuts against the protruding rib 2012. This not only reduces the possibility of the turntable 21 moving towards the switch body 1 after being installed in the auxiliary terminal box 20, but also reduces the possibility of the turntable 21 moving away from the switch body 1 after being installed in the auxiliary terminal box 20, further improving the positional stability of the turntable 21 in the auxiliary terminal box 20.

[0127] Furthermore, by having the thickened portion 213 abut against the protruding rib 2012 on the terminal cover 201, compared to the thickened portion 213 directly abutting against the terminal cover 201, the contact area between the thickened portion 213 and the terminal cover 201 can be reduced. This reduces the frictional force between the thickened portion 213 of the turntable 21 and the terminal cover 201 when the turntable 21 rotates relative to the terminal cover 201. This not only reduces wear on the thickened portion 213 and the terminal cover 201, but also reduces the loss of driving force transmitted to the turntable 21.

[0128] Please continue to refer to Figure 2 , Figure 8 and Figure 11 In some possible implementations, when the connecting part 212 has a circular plate structure, the terminal cover 201 facing the contact housing 100 may also be provided with an arc plate 2013, which cooperates with the surrounding side wall of the connecting part 212 except for the position where the trigger part 210 is provided.

[0129] Figure 8 The illustrated curved plate 2013 is a short curved plate with a small size. There are two curved plates 2013, which are spaced apart and symmetrically arranged. In actual design, the number of curved plates 2013 can also be three or four, or the curved plate 2013 can also be a complete circular plate. This application does not limit this.

[0130] An arc-shaped plate 2013 is disposed on the periphery of the connecting portion 212. When the turntable 21 is installed in place on the auxiliary terminal box 20, the arc-shaped plate 2013 contacts part of the periphery of the connecting portion 212 in the turntable 21, which is equivalent to the fit between a shaft and a bushing. When the turntable 21 rotates relative to the auxiliary terminal box 20, the connecting portion 212 rotates relative to the arc-shaped plate 2013 along the path defined by the arc-shaped plate 2013. In this way, the arc-shaped plate 2013 can limit the rotation of the turntable 21, improving the stability and reliability of the rotation of the turntable 21.
