Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to an installation structure. Background Technology

[0002] A disconnecting switch is a widely used switching device in power systems. The core features of a disconnecting switch are that when it is in the open position, the contacts have a specified insulation distance and a clear disconnection mark, and when it is in the closed position, it can carry current under normal circuit conditions as well as current under abnormal conditions for a specified time.

[0003] Microswitches are a key auxiliary control component within disconnecting switches. Their core function is to monitor the open or closed status of the disconnecting switch, enabling status feedback, interlocking protection, and automated control to ensure the safe and stable operation of the power system. However, existing installation methods for microswitches in disconnecting switches have limitations. Utility Model Content

[0004] This application provides an installation structure to reduce the limitations of microswitch installation methods.

[0005] Firstly, this application provides an installation structure for use with a disconnecting switch, the disconnecting switch including a micro switch. The installation structure includes a housing, a base, and a partition. The housing has a receiving cavity. The base is disposed within the receiving cavity and includes a first side plate, a second side plate, and a bottom plate, which are sequentially connected to form a U-shaped structure. The partition is disposed on the bottom plate, dividing the inner cavity of the U-shaped structure into a first installation space and a second installation space, each of which can accommodate a micro switch.

[0006] Compared to existing technologies, traditional solutions employ an integrated installation structure, with the number of microswitches fixed to the number of mounting slots within the disconnector. This solution, through a partitioned base structure, allows for free switching between two configuration modes within the same space. Existing technologies require redesigning the installation structure when changing switch types, while this solution only requires selecting the corresponding installation space to install either a single or dual microswitch. This application achieves standardization and modularization of the microswitch installation structure. The U-shaped base provides a stable support reference for the switch. The partition physically isolates the inner cavity of the U-shaped structure, effectively preventing mechanical interference between different microswitches. Furthermore, this design allows for the retention of the single microswitch installation function while expanding to a dual microswitch configuration, all while maintaining the original housing dimensions, through the first and second installation spaces. Thus, when the disconnector needs upgrading or maintenance, operators can replace components in specific installation spaces without disassembling the entire disconnector. This design significantly reduces the cost of disconnector modification while improving the versatility and maintainability of the installation structure, thereby mitigating the limitations of microswitch installation methods.

[0007] In one possible design, the base is detachably connected to the housing.

[0008] Through the above solution, this application achieves independent maintenance of the micro switch, allowing operators to replace components without disassembling the main body of the disconnect switch, significantly reducing the upgrade cost of the disconnect switch. Simultaneously, this structure enables different models of micro switches to be compatible with the same housing, improving product compatibility.

[0009] In one possible design, the housing has a first snap-fit, and the first side plate has a slot. The snap-fit ​​engages with the slot.

[0010] The above solution solves the problems of insufficient structural stability and low disassembly and assembly efficiency when the base and the housing are detachably connected. The axial rigid constraint is achieved by the elastic cooperation between the first buckle and the slot, which prevents the base from shifting or shaking in the housing. At the same time, the disassembly and assembly operation can be completed by simply pressing, which improves the convenience of maintenance.

[0011] In one possible design, the housing also includes a second latch, which is positioned to one side of the first latch and corresponds in position to it. The base plate has a through groove, and a positioning block is located on one side of the through groove. The second latch passes through the through groove into the inner cavity of the U-shaped structure and engages with the positioning block.

[0012] Through the above-described solution, this application adds symmetrically distributed second buckles, combined with positioning blocks, to create a double constraint on the base within the housing, effectively resisting torsional torque and axial tension. The corresponding double-buckle design of this application balances the forces on both sides of the base, preventing structural deformation caused by stress concentration. The through-slot design prevents interference between the second buckle and the base plate, thus improving the reliability of the second buckle.

[0013] In one possible design, the first side plate is close to the first mounting space, and the through slot and positioning block are both located in the second mounting space.

[0014] With the above solution, since the base includes a first mounting space and a second mounting space, when the first side plate is close to the first mounting space, the slot can be brought close to the first mounting space. The through slot and the positioning block are both located in the second mounting space. In this way, when the first buckle engages with the slot and the second buckle engages with the positioning block, the base can be better limited, reducing the probability of the other side of the base twisting due to only one side being fixed.

[0015] In one possible design, the housing also includes a first baffle and a second baffle. The first baffle is located on the side of the first latch away from the first side plate, and there is a gap between the first baffle and the first latch. The second baffle is located on the side of the second latch away from the positioning block, and the base has a clearance groove through which the second baffle enters the inner cavity of the U-shaped structure, and there is a gap between the second baffle and the second latch.

[0016] Through the above-described solution, this application adds a rigid limiting function by setting a first baffle on one side of the first buckle and a second baffle on one side of the second buckle, with gaps between the first baffle and the first buckle, and gaps between the second baffle and the second buckle. This solution controls the buckle deformation within a safe range through gap design, avoiding failure caused by plastic deformation. Furthermore, the gap fit between the first baffle and the first buckle, and the gap fit between the second baffle and the second buckle, ensures uniform force distribution on the buckles during base disassembly, avoiding structural damage caused by localized stress concentration and extending the service life of the installation structure. The clearance groove not only reduces interference between the second baffle and the base plate but also guides the second baffle.

[0017] In one possible design, the housing has a groove. The base is located within the groove, and the base is interference-fitted with the housing.

[0018] Through the above-described solution, this application achieves a detachable connection between the base and the housing by using an interference fit between the base and the groove, ensuring the stability of the base installation. This application allows for maintenance where only the base and the microswitch it supports need to be replaced, without replacing the entire housing components, thus reducing the maintenance cost of the disconnecting switch. The reusable disassembly and reassembly of the base and housing also improves the disconnecting switch's compatibility with different models of microswitches; when upgrading the disconnecting switch, only the base needs to be replaced to complete the functional expansion.

[0019] In one possible design, the housing includes a first sidewall and a second sidewall, which correspond to each other. When the base is disposed within the receiving cavity, the second sideplate abuts against the second sidewall. The housing also includes a first reinforcing rib disposed within the receiving cavity, with one end of the first reinforcing rib connected to the first sidewall and the other end abutting against the first sideplate.

[0020] Through the above-described solution, this application significantly improves the sidewall's resistance to deformation without increasing the overall size of the housing by setting a first reinforcing rib. The first reinforcing rib abuts against the first side plate, and the second side plate contacts the second sidewall of the housing, also limiting the base in a first direction. This first direction can be parallel to the arrangement direction of the first and second sidewalls. Since the microswitch is mounted on the base, when the base's position is limited, it ensures that the microswitch maintains contact alignment accuracy during long-term use, reducing the risk of switch malfunction due to instability in the mounting structure.

[0021] In one possible design, the housing includes a second reinforcing rib, which is arranged parallel to the first reinforcing rib. One end of the second reinforcing rib is connected to the first sidewall, and the other end is connected to the second sidewall. The housing also includes a positioning post, which is disposed on one side of the second reinforcing rib, and a base is located between the second reinforcing rib and the positioning post. One side of the base plate abuts against the second reinforcing rib, and the other side of the base plate abuts against the positioning post.

[0022] Through the above-described design, the second reinforcing rib enhances the rigidity of the shell structure, preventing deformation caused by external forces and ensuring the stability of the base's mounting reference surface. The bidirectional limiting mechanism formed by the positioning post and the second reinforcing rib precisely controls the base's installation position within the cavity, avoiding poor microswitch contact due to assembly errors.

[0023] In one possible design, the base also includes a pad disposed within the second mounting space. A microswitch is disposed on the pad to allow space for the second latch, the positioning block, and the second baffle.

[0024] Through the above solution, this application eliminates structural interference by adding independent pads and utilizing a vertically layered layout without changing the standard size of the microswitch. This application solves the positioning conflict problem of installing multiple microswitches when the internal space of the disconnector is limited, allowing standard-sized microswitches to avoid the second latch, the second baffle, and the positioning block. This enables the parallel arrangement of two microswitches in a limited space, while ensuring the stable operation of the multi-stage snap-fit ​​structure between the base and the housing.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] The terms "comprising" and "having," and any variations thereof, used in the specification, claims, and drawings of this application are intended to cover without excluding other meanings. The words "a" or "an" do not exclude the presence of multiples.

[0036] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application.

[0039] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, "connection" or "joining" in mechanical structures can refer to a physical connection.

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

[0041] In existing technologies, the installation methods of microswitches in disconnectors have limitations. Traditional designs often use two microswitches installed on opposite sides of the housing cavity. This necessitates replacing the entire disconnector when upgrading the equipment. For example, during power system renovations, when upgrading from a single microswitch to a dual microswitch configuration, the existing installation structure is incompatible with the new components, requiring the complete removal and replacement of the entire device. This rigid structural design not only increases equipment maintenance costs but also extends system downtime.

[0042] To address the aforementioned issues, this application provides an installation structure that reduces the limitations of microswitch installation methods.

[0043] 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.

[0044] Figure 1 This is a schematic diagram of the overall structure of the disconnecting switch provided in an embodiment of this application. Figure 2 for Figure 1 A magnified view of section A. Figure 3 This is a schematic diagram of the structure of the base provided in an embodiment of this application. Figures 1 to 3As shown, this application provides an installation structure for use with a disconnecting switch, which includes a micro switch 300. The installation structure includes a housing 100, a base 200, and a partition 240. The housing 100 has a receiving cavity. The base 200 is disposed within the receiving cavity and includes a first side plate 210, a second side plate 220, and a bottom plate 230, which are sequentially connected to form a U-shaped structure. The partition 240 is disposed on the bottom plate 230, dividing the inner cavity of the U-shaped structure into a first installation space and a second installation space, each of which can accommodate a micro switch 300.

[0045] The U-shaped structure refers to an open frame structure composed of three planar components, which can be achieved by injection molding. The first side plate 210 and the second side plate 220 are arranged parallel to each other on both sides of the base plate 230, thus forming a stable support structure.

[0046] Partition 240 refers to a partition component vertically installed on the base plate 230. Partition 240 can be integrally formed with the base 200, or partition 240 can be installed on the base plate 230 after the base 200 is formed by snap-fit ​​or adhesive. The height of partition 240 can be less than the height of the first side plate 210 and the height of the second side plate 220, so that two independent cavities can be formed within the U-shaped structure. The first installation space and the second installation space refer to two independent cavities physically separated by partition 240. Specifically, the size ratio of the first installation space and the second installation space can be changed by adjusting the position of partition 240.

[0047] Specifically, the housing 100 serves as the primary load-bearing structure, and its internal cavity provides a fixed reference for the base 200. When the base 200 is installed within the cavity, the opening direction of the U-shaped structure is perpendicular to the mounting surface of the housing 100, forming a stable three-dimensional support system. The partition 240 divides the inner cavity of the U-shaped structure into two independent areas. In a single microswitch 300 application scenario, the microswitch 300 only needs to be fixed within the first or second mounting space, leaving the other area unused. In a dual microswitch 300 configuration, both the first and second mounting spaces can simultaneously support the microswitches 300. This design allows for selective installation of the microswitch 300.

[0048] In summary, compared with existing technologies, traditional solutions employ an integrated installation structure, with the number of microswitches 300 fixedly corresponding to the mounting slots within the disconnector. This solution, through a partitionable base 200, allows for free switching between two configuration modes within the same space. Existing technologies require redesigning the installation structure when changing switch types, while this solution only requires selecting the corresponding installation space to install either a single microswitch 300 or two microswitches 300.

[0049] This application achieves standardization and modularization of the mounting structure of the micro switch 300. The U-shaped base 200 provides a stable support reference for the switch. The partition 240 physically isolates the inner cavity of the U-shaped structure, which can effectively prevent mechanical interference between different micro switches 300. Moreover, this arrangement can retain the installation function of a single micro switch 300 and expand the configuration of dual micro switches 300 by using the first mounting space and the second mounting space, while keeping the original housing 100 size unchanged.

[0050] In this way, when the disconnector needs to be upgraded or maintained, operators can replace components for specific installation spaces without disassembling the entire disconnector. This design significantly reduces the cost of retrofitting the disconnector while improving the versatility and maintainability of the installation structure, thereby mitigating the limitations of the microswitch 300 installation method.

[0051] Please continue to refer to Figures 1 to 3 As shown, this application further proposes that the base 200 and the housing 100 can be assembled by a detachable connection.

[0052] The detachable connection refers to the repeated assembly and disassembly of the base 200 and the housing 100 through a mechanically coordinated structure. The purpose of the detachable connection is to make the base 200 an independent module. When it is necessary to maintain the micro switch 300, the base 200 can be removed separately simply by disconnecting the connection between the base 200 and the housing 100.

[0053] Specifically, the base 200 is configured as an independent unit that can be completely separated from the receiving cavity of the housing 100, and a micro switch 300 is mounted on the base 200. When it is necessary to replace the micro switch 300, the base 200 is detached from the housing 100, at which point the micro switch 300 on the base 200 can be directly disassembled or installed. After maintenance is completed, the base 200 is reinserted into the housing 100 and secured, thereby restoring the functional integrity of the disconnector.

[0054] Compared to existing technologies, in traditional disconnect switches, the base 200 and housing 100 are connected by welding or integral molding, which requires the entire microswitch 300 to be disassembled for maintenance. This solution, however, uses a detachable connection structure, making the base 200 an independent, replaceable module, thus avoiding the resource waste caused by replacing the entire unit.

[0055] Through the above technical solution, this application achieves independent maintenance of the micro switch 300, allowing operators to replace components without disassembling the main body of the disconnect switch, significantly reducing the upgrade cost of the disconnect switch. Simultaneously, this structure enables different models of micro switches 300 to be compatible with the same housing 100, improving product compatibility.

[0056] Figure 4 This is a schematic diagram of the structure of the housing provided in an embodiment of this application. Figure 5 for Figure 4 A magnified view of section B. Further, as... Figures 3 to 5 As shown, the housing 100 is provided with a first buckle 110, and the first side plate 210 is provided with a slot 211. The buckle is engaged in the slot 211.

[0057] The first latch 110 refers to an elastic locking component disposed on the housing 100, which engages and disengages with the latch 211 through elastic deformation. The latch 211 refers to a groove structure formed on the first side plate 210, the geometry of which matches the shape of the end of the first latch 110 not connected to the housing 100 to form a constraint. The latch 211 can be a through groove structure or a blind groove structure with its opening facing the first latch 110.

[0058] Specifically, when the base 200 is inserted into the receiving cavity of the housing 100, the first latch 110 undergoes elastic deformation under external force until the end of the first latch 110 not connected to the housing 100 is embedded in the slot 211 of the first side plate 210. At this time, the first latch 110 returns to its initial shape, and the end of the first latch 110 not connected to the housing 100 forms rigid contact with the groove wall of the slot 211 to limit the displacement of the base 200. When it is necessary to disassemble the base 200, the first latch 110 is pressed to disengage it from the slot 211, and the base 200 can be removed from the housing 100. This structure, through the combination of elastic latching and rigid constraint, achieves quick assembly and disassembly while ensuring connection stability.

[0059] Through the above technical solution, this application solves the problems of insufficient structural stability and low disassembly and assembly efficiency when the base 200 and the housing 100 are detachably connected. The axial rigid constraint is achieved by the elastic cooperation between the first buckle 110 and the slot 211, which prevents the base 200 from shifting or shaking inside the housing 100. At the same time, the disassembly and assembly operation can be completed by simply pressing, which improves the convenience of maintenance.

[0060] Further, please continue to refer to Figures 3 to 5 As shown, the housing 100 is also provided with a second latch 120, which is located on one side of the first latch 110 and corresponds to the position of the first latch 110. The bottom plate 230 is provided with a through groove 250, and a positioning block 260 is provided on one side of the through groove 250. The second latch 120 enters the inner cavity of the U-shaped structure through the through groove 250 and engages with the positioning block 260.

[0061] The second snap-fit ​​120 refers to an elastic snap-fit ​​component arranged parallel to the first snap-fit ​​110. The second snap-fit ​​120 and the first snap-fit ​​110 can together form symmetrically distributed snap-fit ​​points. The through slot 250 refers to a rectangular opening formed on the base plate 230. The size of the through slot 250 can be slightly larger than the size of the second snap-fit ​​120 to facilitate assembly. The positioning block 260 refers to a boss structure fixed to one side of the through slot 250. The positioning block 260 can be integrally formed with the base 200, or the positioning block 260 can be set on the base 200 after the base 200 is formed by snap-fit ​​or adhesive.

[0062] Specifically, during the assembly of the base 200 and the housing 100, the second latch 120 can enter the inner cavity of the U-shaped structure along the through groove 250 and engage with the positioning block 260. When the base 200 is fully installed into the housing 100, the first latch 110 and the second latch 120 respectively engage with the slot 211 of the first side plate 210 and the positioning block 260, forming a symmetrical fixing structure. This double-clamping design allows the two latches to share the load when the base 200 is subjected to external forces, avoiding displacement of the base 200 caused by the failure of a single-sided latch.

[0063] Compared to existing technologies, traditional solutions use only a single snap-fit ​​to fix the base 200, which is prone to snap-fit ​​failure under frequent disassembly or vibration environments. This solution adds symmetrically distributed second snap-fits 120, combined with positioning blocks 260, to create a double constraint on the base 200 within the housing 100, effectively resisting torsional torque and axial tension. The corresponding double-snap-fit ​​design in this application balances the forces on both sides of the base 200, preventing structural deformation caused by stress concentration. The through-slot 250 design prevents interference between the second snap-fit ​​120 and the base plate 230, thus improving the reliability of the second snap-fit ​​120.

[0064] Figure 6 This is an assembly diagram of the base and housing provided in an embodiment of this application. Figure 7 for Figure 6 A magnified view of section C. (See image.) Figure 6 as well as Figure 7 As shown, the first side plate 210 is close to the first mounting space, and the through groove 250 and the positioning block 260 are both located in the second mounting space.

[0065] Specifically, when the base 200 is assembled to the housing 100, the first side plate 210 is arranged adjacent to the first mounting space, allowing the first latch 110 to directly engage with the slot 211 of the first side plate 210 for positioning. The through slot 250 and the positioning block 260 are confined within the second mounting space to prevent them from extending into the first mounting space area. Within the second mounting space, the second latch 120 enters through the through slot 250 and engages with the positioning block 260.

[0066] Through the above technical solution, since the base 200 includes a first mounting space and a second mounting space, when the first side plate 210 is close to the first mounting space, the slot 211 can be brought close to the first mounting space. The through slot 250 and the positioning block 260 are both located in the second mounting space. In this way, when the first buckle 110 engages with the slot 211 and the second buckle 120 engages with the positioning block 260, the base 200 can be better limited, reducing the probability of the other side of the base 200 twisting due to only one side being fixed.

[0067] Furthermore, to improve the reliability of the first latch 110 and the second latch 120, please refer to... Figures 3 to 5 As shown, the housing 100 also includes a first baffle 130 and a second baffle 140. The first baffle 130 is located on the side of the first latch 110 away from the first side plate 210, and there is a gap between the first baffle 130 and the first latch 110. The second baffle 140 is located on the side of the second latch 120 away from the positioning block 260. The base 200 is provided with a clearance groove 270, through which the second baffle 140 enters the inner cavity of the U-shaped structure, and there is a gap between the second baffle 140 and the second latch 120.

[0068] The first baffle 130 refers to a plate-like structure disposed on the housing 100 and spaced apart from the first buckle 110. The gap width between the first baffle 130 and the first buckle 110 can be 0.5-1 mm. This gap can provide space for the elastic deformation of the first buckle 110, while limiting the lateral displacement range of the first buckle 110.

[0069] The second baffle 140 refers to a plate-like structure disposed on the housing 100 and spaced apart from the second latch 120. The gap width between the second baffle 140 and the second latch 120 can be 0.8-1.2 mm. This gap can provide space for the elastic deformation of the second latch 120, while limiting the lateral displacement range of the second latch 120.

[0070] The clearance groove 270 refers to an opening structure formed on the side of the base 200. The size of the clearance groove 270 can be slightly larger than the thickness of the second baffle 140 to achieve a guiding function. The clearance groove 270 can be connected to the through groove 250, or the clearance groove 270 and the through groove 250 can be respectively set on the base plate 230.

[0071] Specifically, the clearance fit between the first baffle 130 and the first latch 110 forms the first level of constraint on the lateral movement of the base 200. When the base 200 is subjected to external force, the first latch 110 undergoes elastic deformation within the allowable range of the clearance, while the first baffle 130 prevents it from exceeding the deformation limit. After the second baffle 140 enters the U-shaped structure through the relief groove 270, it forms the second level of constraint on the lateral movement of the base 200 with the clearance fit between it and the second latch 120. The elastic deformation of the second latch 120 is limited within the clearance range.

[0072] In summary, this solution, by setting a first baffle 130 on one side of the first buckle 110 and a second baffle 140 on one side of the second buckle 120, and by creating gaps between the first baffle 130 and the first buckle 110, and between the second baffle 140 and the second buckle 120, adds a rigid limiting function while retaining the elastic connection characteristics of the first buckle 110 and the second buckle 120. This solution controls the buckle deformation within a safe range through gap design, avoiding failure caused by plastic deformation. Furthermore, the gap fit between the first baffle 130 and the first buckle 110, and between the second baffle 140 and the second buckle 120, ensures uniform force distribution on the buckles during the disassembly of the base 200, avoiding structural damage caused by localized stress concentration and extending the service life of the installation structure. The clearance groove 270 not only reduces interference between the second baffle 140 and the base plate 230, but also serves as a guide for the second baffle 140.

[0073] Since both the clearance slot 270 and the through slot 250 are located within the second mounting space, the second latch 120 and the second baffle 140 can pass through the base plate 230 and enter the second mounting space. However, the second mounting space is used to install the micro switch 300. Based on this, such as Figure 2 as well as Figure 3 As shown, the base 200 also includes a pad 280, which is disposed within the second mounting space. A micro switch 300 is disposed on the pad 280 to make way for the second latch 120, the positioning block 260, and the second baffle 140.

[0074] The pad 280 refers to the raised structure used to support the micro switch 300. The height of the pad 280 is configured to match the engagement depth of the second latch 120, the protruding height of the positioning block 260, and the extension length of the second baffle 140. By raising the micro switch 300 to a preset height, the pad 280 creates a vertical clearance gap between the bottom of the micro switch 300 and the fixed structure in the second mounting space.

[0075] Specifically, the pad 280 is fixed to the upper surface of the base plate 230, and its top surface forms the mounting plane of the micro switch 300. When the micro switch 300 is assembled into the second mounting space, the bottom of the micro switch 300 contacts the top surface of the pad 280.

[0076] In summary, this application eliminates structural interference by adding an independent pad 280 without changing the standard size of the micro switch 300, and utilizes a vertically layered layout. This application solves the positioning conflict problem of installing multiple micro switches 300 when the internal space of the disconnector is limited, allowing the standard-sized micro switch 300 to avoid the second latch 120, the second baffle 140, and the positioning block 260. This enables the parallel arrangement of two micro switches 300 in a limited space, while ensuring the stable operation of the multi-level snap-fit ​​structure between the base 200 and the housing 100.

[0077] In some possible embodiments, this application also provides another method for detachably connecting the base 200 to the housing 100, such as... Figure 1 as well as Figure 3 As shown, the housing 100 may have a groove. The base 200 is located in the groove, and the base 200 is interference-fitted with the housing 100.

[0078] The groove refers to the recessed area formed by processing the surface of the housing 100. Specifically, a rectangular groove structure can be formed in the receiving cavity of the housing 100 by injection molding process. Its depth can be matched with the thickness of the base plate 230 to limit the installation position of the base 200 inside the housing 100.

[0079] An interference fit is an assembly method in which the outer contour dimension of the base 200 is slightly larger than the inner cavity dimension of the groove. The base 200 is fixed in the groove by the clamping force generated by the elastic deformation of the contact surface between the base 200 and the groove.

[0080] Specifically, when the base 200 is inserted into the groove of the housing 100 via an interference fit, a surface contact is formed between the side wall of the base 200 and the groove wall. The frictional force generated by the contact surface counteracts the external force on the base 200. The bottom plane of the groove provides vertical support for the base 200, and the contact pressure between the bottom surface of the base 200 and the bottom surface of the groove can be adjusted by the interference fit. When it is necessary to replace the micro switch 300, a vertical disassembly force can be applied to the base 200 using a tool, causing the base 200 to elastically separate from the interference fit surface of the groove, thus achieving non-destructive disassembly of the base 200 from the housing 100.

[0081] In summary, this application achieves a detachable connection between the base 200 and the housing 100 by using an interference fit between the base 200 and the groove, while ensuring the installation stability of the base 200. This application allows for maintenance where only the base 200 and the micro switch 300 it supports need to be replaced, without replacing the entire housing 100, thus reducing the maintenance cost of the disconnect switch. The reusable disassembly and reassembly of the base 200 and housing 100 also improves the disconnect switch's compatibility with different models of micro switches 300; when upgrading the disconnect switch, only the base 200 needs to be replaced to complete the functional expansion.

[0082] To improve the reliability of the base 200, such as Figure 6 as well as Figure 7 As shown, the housing 100 includes a first sidewall 150 and a second sidewall 160, which correspond to each other. When the base 200 is disposed in the receiving cavity, the second side plate 220 abuts against the second sidewall 160. The housing 100 also includes a first reinforcing rib 170, which is disposed in the receiving cavity. One end of the first reinforcing rib 170 is connected to the first sidewall 150, and the other end of the first reinforcing rib 170 abuts against the first side plate 210.

[0083] The first sidewall 150 and the second sidewall 160 refer to the vertical walls on both sides of the housing 100. The first sidewall 150 and the second sidewall 160 form the boundary support structure of the receiving cavity, which is used to limit the horizontal displacement of the base 200.

[0084] The first reinforcing rib 170 refers to the support strip set inside the receiving cavity. Specifically, it can be fixedly connected to the first side wall 150 by injection molding process. The other end of the first reinforcing rib 170 remains in a free end state and abuts against the first side plate 210 of the base 200 through surface contact.

[0085] Specifically, when the base 200 is installed into the receiving cavity, the second side plate 220 of the base 200 forms a surface contact with the second side wall 160 of the housing 100, and the movement tendency of the base 200 is restrained by friction. At the same time, one end of the first reinforcing rib 170 is rigidly connected to the first side wall 150, and the other end abuts against the first side plate 210 of the base 200 in a non-fixed manner.

[0086] In summary, by providing the first reinforcing rib 170, this application can significantly improve the deformation resistance of the sidewall without increasing the overall size of the housing 100. The first reinforcing rib 170 abuts against the first side plate 210, and the second side plate 220 contacts the second side wall 160 of the housing 100, and can also limit the base 200 in a first direction. The first direction can be parallel to the arrangement direction of the first side wall 150 and the second side wall 160. Since the micro switch 300 is disposed on the base 200, when the position of the base 200 is limited, it can ensure that the micro switch 300 maintains contact alignment accuracy during long-term use, reducing the risk of switch malfunction due to instability of the mounting structure.

[0087] Further, please continue to refer to Figure 6 as well as Figure 7 As shown, the housing 100 further includes a second reinforcing rib 180, which is arranged parallel to the first reinforcing rib 170. One end of the second reinforcing rib 180 is connected to the first sidewall 150, and the other end is connected to the second sidewall 160. The housing 100 also includes a positioning post 190, which is disposed on one side of the second reinforcing rib 180. The base 200 is located between the second reinforcing rib 180 and the positioning post 190. One side of the base plate 230 abuts against the second reinforcing rib 180, and the other side of the base plate 230 abuts against the positioning post 190.

[0088] The second reinforcing rib 180 refers to a support structure arranged parallel to the first reinforcing rib 170, with its two ends fixedly connected to the first sidewall 150 and the second sidewall 160 of the housing 100, respectively. The positioning post 190 refers to a protruding structure provided on one side of the second reinforcing rib 180, which can be implemented using a cylindrical boss or a prismatic boss structure.

[0089] Specifically, the second reinforcing rib 180 and the first reinforcing rib 170 are arranged in parallel to form a double transverse support frame. By connecting the first sidewall 150 and the second sidewall 160 of the housing 100 at both ends, the overall deformation resistance of the housing 100 can be improved. The positioning post 190 is located on the side of the second reinforcing rib 180 and adjacent to the base 200. When the base 200 is installed into the receiving cavity, one side of the base plate 230 of the base 200 contacts the surface of the second reinforcing rib 180, and the other side contacts the sidewall of the positioning post 190, forming physical limits on both sides. This clamping layout prevents the base 200 from shifting in the second direction, thereby ensuring the geometric accuracy of the microswitch 300 installation space. The second direction can be parallel to the arrangement direction of the second reinforcing rib 180 and the positioning post 190.

[0090] Through the above technical solution, the second reinforcing rib 180 can enhance the structural rigidity of the housing 100, prevent deformation of the housing 100 due to external forces, and ensure the stability of the mounting reference surface of the base 200. The bidirectional limiting mechanism formed by the positioning post 190 and the second reinforcing rib 180 can precisely control the installation position of the base 200 in the receiving cavity, avoiding poor contact of the microswitch 300 caused by assembly errors.
