[0002] A magnetic switch is an electronic component that uses a magnetic field signal to control the on / off state of a circuit. It is widely used in scenarios requiring non-contact triggering and strong environmental adaptability. Its core feature is that it eliminates the need for physical pressing, switching circuits solely through a magnetic field, thus combining safety, durability, and concealment.

[0003] The housings of magnetic switches on the market are usually fixed to the equipment by tightening screws. In order to accommodate the effect of screw fixing and structural strength, the housing needs to be made of hard plastic such as ABS. In order to prevent interference with the magnetic switch, stainless steel screws and nuts are also required. In addition, during the tightening process, the stress between the screw and the housing can be easily transmitted to the magnetic switch, which may cause damage to the magnetic switch and thus affect the safety of the magnetic switch.

[0004] To address the aforementioned issues, it is necessary to optimize the assembly and usage processes of magnetic switches in order to further improve assembly stability and the safety of magnetic switches. Utility Model Content

[0005] Regarding the aforementioned technical problem that existing magnetic switch housings are typically fixed to equipment using screws, requiring stainless steel screws and nuts, and the housing needs to be made of hard plastic, which can easily generate stress during assembly and transmit it to the magnetic switch, leading to damage, the technical solution adopted by this utility model to solve this problem is: A magnetic switch protection component includes a housing, the housing having an inner cavity for accommodating the magnetic switch and a locking member, the locking member being connected to the surface of the housing, the locking member being partially or entirely made of a deformable elastic material, and the locking member having a limiting end for engaging with an external opening for limiting.

[0006] Furthermore, in some embodiments of this utility model, the engaging member includes a first connecting portion connected to the housing and a second connecting portion connected to the first connecting portion. The limiting end is a groove or protrusion provided in the first connecting portion and / or the second connecting portion.

[0007] Furthermore, in some embodiments of this utility model, the outer diameter of the second connecting part gradually increases from the side away from the first connecting part to the side closer to the first connecting part, the second connecting part is provided in a conical or frustum shape, and the maximum outer diameter of the second connecting part is greater than the diameter of the external opening.

[0008] Furthermore, in some embodiments of this utility model, the end of the second connecting part is provided with an extension end, the extension end is elastic, the maximum outer diameter of the extension end after deformation is smaller than the aperture of the external opening, and the second connecting part and / or the extension end are made of one of thermoplastic elastomer, thermoplastic polyurethane, silicone, or soft polycarbonate.

[0009] Furthermore, in some embodiments of this utility model, the housing has a first region on one side and a second region on the other side, the housing cavity is disposed in the first region, the engaging member is disposed in the second region, and the axial direction of the housing cavity is perpendicular to the extension direction of the engaging member.

[0010] Furthermore, in some embodiments of this utility model, the ratio of the length L of the extension end to the length M of the second connecting part is 1:3-3:1, and the ratio of the length P of the engaging member to the thickness Q of the housing is 1:3-3:1.

[0011] Furthermore, in some embodiments of this utility model, the length L of the extension end is greater than or equal to the length M of the second connecting portion, and the length P of the engaging member is greater than the thickness Q of the housing.

[0012] Furthermore, in some embodiments of this utility model, the housing and the engaging member are integrally formed, both the housing and the engaging member are made of silicone material, an opening is provided on one side of the inner cavity of the housing, and the housing is provided with a sealing member for sealing the inner cavity of the housing.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that all directional indications in this utility model embodiment, such as (up, down, left, right, front, back, etc.), are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly.

[0028] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0029] like Figures 1 to 10 The magnetic switch protection assembly shown includes a housing 1. The housing 1 has an inner cavity 2 for accommodating the magnetic switch and a locking member 3. The locking member 3 is connected to the surface of the housing 1. The locking member 3 is partially or entirely made of a deformable elastic material. The locking member 3 has a limiting end 31 that cooperates with an external opening for limiting.

[0030] This invention uses a locking component made of deformable elastic material on the surface of the housing to fix the housing by limiting the engagement between the locking component and the opening of the external device. This replaces the mechanical fixing method of screw tightening in the traditional technology, and avoids the transmission of assembly stress generated when the bolts are tightened to the inner cavity of the housing. This effectively reduces the risk of structural damage or performance degradation of the magnetic switch due to stress, thereby improving the safety and reliability of the magnetic switch.

[0031] Specifically, this invention does not rely on metal fasteners such as screws and nuts for fixing, avoiding the problem of traditional technologies that require the use of screws made of specific materials such as stainless steel to prevent interference with the magnetic switch. This reduces potential interference factors on the magnetic field sensing of the magnetic switch, helps maintain the magnetic sensitivity and triggering accuracy of the magnetic switch, and improves its working stability. This invention also reduces the cost of using screws and nuts. By reducing the number of parts and the cumbersome operation in the assembly process, and without the structural limitations of screw fastening, the housing of this invention no longer needs to be made of high-strength hard plastic material to accommodate screw tightening. It can use materials with good elasticity, impact resistance, or sealing properties, including but not limited to soft plastic, TPU, silicone, etc., thereby ensuring protective performance while improving the adaptability of the housing and facilitating better sealing and protection effects.

[0032] In addition, the snap-fit ​​parts are partially or entirely made of deformable elastic material, which can quickly snap into or fasten to the openings or grooves on the equipment through elastic deformation, thereby achieving quick assembly and disassembly without the need for additional tools. Compared with the traditional screw tightening method, it is easier to operate, improves assembly efficiency, and reduces the risk of the housing falling off due to inconsistent tightening during the assembly process.

[0033] Optionally, in some embodiments, the engaging part can be integrally formed on the surface of the housing, or it can be detachably connected to the housing. In some embodiments, the engaging part can be engaged with the housing through snap-fit ​​connection, mortise and tenon connection, groove connection, or threaded connection, so as to adapt to different equipment installation scenarios by replacing the engaging part.

[0034] Optionally, in some embodiments, the limiting end can be a groove or a protrusion. In some embodiments, after the partially elastic engaging portion passes through the external opening via an interference fit, the external opening is connected to the limiting end forming the groove space. In some embodiments, after the partially elastic limiting end passes through the external opening via an interference fit, the protruding limiting end is reset and restricts the external opening from disengaging from the limiting end in the opposite direction.

[0035] Optionally, in some embodiments, the magnetic switch may be a Hall element type magnetic switch or a reed switch type magnetic switch.

[0036] like Figures 1 to 4 The magnetic switch protection assembly shown includes a locking member 3 comprising a first connecting part 4 connected to the housing 1 and a second connecting part 5 connected to the first connecting part 4. The limiting end 31 is a groove or protrusion provided on the limiting end 4 and / or the second connecting part 5. The maximum outer diameter of the second connecting part 5 is greater than the minimum outer diameter of the first connecting part 4. The second connecting part 5 is elastic and has a guide surface 51.

[0037] Specifically, in some embodiments, such as Figure 5 , Figure 6 As shown, the limiting end is part of the first connecting portion, or as... Figure 7 , Figure 8 , Figure 10 As shown, it is part of the second connecting part, or as... Figure 9 As shown, this is the portion that is located simultaneously in the first connecting part and the second connecting part.

[0038] Additionally, in some embodiments, such as Figure 10 As shown, the limiting end can be connected to the first connecting part as the second connecting part, or the limiting end can be connected to the second connecting part as the first connecting part.

[0039] Alternatively, a groove can refer to a positioning groove formed between connectors with different diameters on the front and back sides, or it can refer to a locking groove set on both the front and back sides with the same diameter.

[0040] Alternatively, a protrusion can refer to a boss with a larger end diameter formed between connecting parts with different diameters on the front and rear sides along the axial direction, or it can be a protrusion extending in the axial direction outside the second or first connecting part. There can be multiple protrusions along the axial direction that are elastically movable, or they can be arranged in a ring and deformable.

[0041] Optionally, in some embodiments, the second connecting part is made of an elastic material or structure, and its maximum outer diameter is greater than the minimum outer diameter of the first connecting part. This allows the second connecting part to undergo elastic deformation when the engaging member is inserted into the opening on the external device. The limiting effect is achieved through interference fit or compression. After being inserted into place, the second connecting part restores its deformation and fits tightly against the inner wall of the opening or the edge of the slot, forming a stable holding effect. This prevents the housing from falling off or loosening, thereby improving the overall assembly's firmness and stability.

[0042] Optionally, in some embodiments, the limiting end can be a groove provided between the first connecting part and the second connecting part. When the engaging member is inserted into the external opening, the groove can serve as a positioning reference point or a snap-in feedback position during the engaging process under the action of external force. The groove can also serve as an auxiliary limiting part that cooperates with the external structure, thereby enhancing the positioning accuracy of the overall engaging structure.

[0043] Specifically, the second connecting part is provided with a guide surface, which can guide the snap-fit ​​part when it is inserted into the external opening or slot, making it easier for the second connecting part to enter the installation position and avoiding jamming or assembly difficulties caused by size mismatch or angular deviation. Furthermore, the setting of the guide surface effectively reduces the insertion force required during assembly, thereby improving the smoothness of assembly.

[0044] In addition, the second connection part adopts an elastic design, which enables it to maintain a certain self-adjusting ability when it is used for a long time or affected by external environmental factors such as vibration and impact. It compensates for the fit gap through slight deformation, maintains a stable engagement state, and prevents loosening due to environmental changes.

[0045] like Figures 1 to 4 The magnetic switch protection assembly shown has a second connecting part 5 whose outer diameter gradually increases from the side away from the first connecting part 4 to the side closer to the first connecting part 4. The second connecting part 5 is conical or frustum-shaped, and the maximum outer diameter of the second connecting part 5 is greater than the diameter of the external opening.

[0046] Furthermore, as a preferred embodiment of this utility model and not a limitation, the second connecting part is conical or frustum-shaped, and its maximum outer diameter is larger than the diameter of the external opening. This provides a guiding function during assembly, helping to guide the second connecting part into the external opening in the initial stage of assembly, reducing initial insertion resistance and minimizing jamming. The second connecting part needs to undergo elastic deformation under external force to pass through the external opening. After passing through the opening, as its outer diameter gradually increases, the second connecting part will form an interference fit with the inner wall of the opening, relying on elastic restoring force to tightly adhere to the edge of the opening, forming a reliable wedging and self-locking effect, effectively preventing the housing from loosening or shifting under external force.

[0047] Specifically, the second connecting part is made of elastic material or structure. When it needs to be disassembled, the second connecting part can be elastically deformed again by applying appropriate external force, so as to smoothly exit the opening. It has the characteristics of easy installation and disassembly, which not only ensures the stability of the assembly, but also provides convenience for later maintenance.

[0048] like Figures 1 to 4 The magnetic switch protection assembly shown has an extension end 6 at the end of the second connecting part 5. The extension end 6 is elastic, and the maximum outer diameter of the extension end 6 after deformation is smaller than the diameter of the external opening. The second connecting part 5 and / or the extension end 6 are made of one of thermoplastic elastomer, thermoplastic polyurethane, silicone, or soft polycarbonate.

[0049] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, since the extension end is elastic and its maximum outer diameter after deformation is smaller than the diameter of the external opening, in the initial stage of assembly, the extension end can easily undergo elastic deformation and pass through the external opening, thereby guiding the entire engaging part smoothly into the installation position, effectively reducing the insertion resistance at the beginning of assembly and improving the smoothness and convenience of assembly operation.

[0050] Specifically, the extension end, as an elastic guide structure at the front end of the snap-fit ​​component, can enter the external opening first during the insertion process, playing a guiding and positioning role, helping the operator to accurately align the installation hole, avoiding jamming, damage or assembly failure caused by misalignment or skewness, and improving the operational accuracy of the assembly process.

[0051] In addition, the extension end is elastic, which can absorb part of the assembly impact force during insertion, avoiding mechanical damage to the second connection part, housing or magnetic switch due to excessive instantaneous insertion force, thus helping to improve the safety of the assembly process.

[0052] Specifically, thermoplastic elastomers, thermoplastic polyurethanes, silicone, and soft polycarbonate all have good elasticity, flexibility, and reversible deformation properties, which allows the second connecting part and / or extension end to undergo moderate elastic deformation during assembly, thereby smoothly passing through the external opening. After passing through, the material's own elastic recovery force forms a stable interference fit with the inner wall of the opening, achieving reliable locking and self-locking fixation, effectively preventing the magnetic switch protection component from loosening or shifting, and improving the stability of the assembly and the reliability of the connection.

[0053] In addition, the damping characteristics and vibration resistance of materials such as thermoplastic elastomers, thermoplastic polyurethanes, and silicone can effectively absorb and mitigate external vibration and impact energy during equipment operation, reducing the loosening and displacement of magnetic switch protection components caused by environmental disturbances.

[0054] Furthermore, thermoplastic elastomers, thermoplastic polyurethanes, silicone and soft polycarbonates are all suitable for conventional injection molding, extrusion molding or compression molding processes, and have good flowability, formability and mass production consistency. This allows the second connection and / or extension to be manufactured using efficient and low-cost production methods, which not only helps to ensure the consistency of product dimensional accuracy and structural strength, but also helps to improve overall production efficiency and reduce manufacturing costs.

[0055] like Figures 1 to 4 The magnetic switch protection assembly shown has a first region 7 on one side and a second region 8 on the other side of the housing 1. The housing cavity 2 is located in the first region 7, and the engaging member 3 is located in the second region 8. The axial direction of the housing cavity 2 is perpendicular to the extension direction of the engaging member 3.

[0056] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, by setting the inner cavity of the housing and the engaging member respectively in the first and second regions of the housing, the functional partitioning and spatial isolation of the magnetic switch accommodating function and the housing fixing function are realized, so that the internal structure of the housing and the external fixing structure do not interfere with each other, which is conducive to optimizing the overall structural layout, improving space utilization, making the housing design more compact and reasonable, and facilitating the effective protection of the magnetic switch and the stable installation of the housing in a limited space.

[0057] Specifically, the axial direction of the inner cavity of the housing is perpendicular to the extension direction of the engaging member. The magnetic switch, which is arranged along the axial direction of the inner cavity of the housing, is perpendicular to the direction of the external force applied when the housing is fixed. This effectively avoids the stress being directly transmitted along the sensitive axis of the magnetic switch when the engaging member is subjected to external forces such as pulling, squeezing, or torsion during the fixing process or use. This reduces the risk of structural damage or performance failure of the magnetic switch due to assembly or environmental stress, and improves the safety and reliability of the magnetic switch.

[0058] In addition, the partitioned layout and axially vertical structural design of this utility model allow the housing to flexibly adapt to different installation directions and spatial arrangement requirements. By producing housings with different orientation layouts, the inner cavity of the housing can be set in different positions such as upward, downward, or sideways. At the same time, the extension direction of the locking component can be flexibly adjusted according to the position of the equipment mounting hole, which improves the adaptability and versatility of the magnetic switch protection component in different equipment and different installation environments, and helps to expand the application range of the product.

[0059] like Figures 1 to 4 , Figure 7 and Figure 8 The magnetic switch protection assembly shown has a length L of the extension end 6 and a length M of the second connecting part 5 in a ratio of 1:3 to 3:1, and a length P of the engaging member 3 and a thickness Q of the housing 1 in a ratio of 1:3 to 3:1.

[0060] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, by limiting the ratio of the length L of the extended end to the length M of the second connecting part to the range of 1:3 to 3:1, it is made to have sufficient length to achieve good assembly guidance, elastic buffering and initial insertion performance, while not being excessively extended to cause a decrease in the structural strength of the overall engaging part or excessive assembly guidance. Thus, while ensuring smooth assembly and reducing insertion resistance, the overall structural stability and reliable engaging performance of the engaging part are maintained, and the operability and safety of the assembly process are improved.

[0061] Specifically, by setting the ratio of the length P of the engaging component to the thickness Q of the housing within the range of 1:3 to 3:1, it can be effectively ensured that while the engaging component achieves a stable engaging function, its length is reasonably matched with the thickness of the housing. This prevents the engaging component from being too short, resulting in insecure fixation and easy loosening, or from being too long, exceeding the housing boundary, affecting the aesthetics of the assembly, or interfering with the surrounding structure. Thus, while ensuring a firm and reliable connection between the magnetic switch protection component and the equipment, the feasibility and structural coordination of the overall assembly are improved.

[0062] In addition, by avoiding wasted or insufficient assembly space due to excessively long or short locking components, it helps to achieve a miniaturized, compact, and rational layout of the overall structure of the magnetic switch protection component, making it suitable for equipment environments with limited installation space and strict structural requirements, thereby improving the product's adaptability and engineering applicability.

[0063] like Figures 1 to 4 , Figure 7 and Figure 8 The magnetic switch protection assembly shown has an extension end 6 with a length L greater than or equal to the length M of the second connecting part 5, and a locking member 3 with a length P greater than the thickness Q of the housing 1.

[0064] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, by setting the length L of the extension end to be greater than or equal to the length M of the second connecting part, the elastic guiding part at the front end of the engaging member has a more sufficient length, thereby enabling it to more effectively perform its guiding, buffering, and initial introduction functions during assembly. The longer extension end can preferentially contact and guide the engaging member into the external opening, reducing the initial insertion resistance and improving the smoothness and accuracy of the assembly operation. It is especially suitable for application scenarios with small mounting hole diameters, high assembly precision requirements, or limited operating space. At the same time, it helps to reduce the impact of assembly stress on the main body of the second connecting part and the inner cavity of the housing, protecting the structural safety of the magnetic switch.

[0065] Specifically, the structural design of extending the length L to be no less than the length M of the second connection part makes the elastic deformation area relatively longer, which can more fully absorb the impact force and deformation energy generated during the assembly process, avoid structural damage caused by excessive instantaneous insertion force, help improve the safety and reliability of the assembly process, and is suitable for occasions where magnetic switches are more sensitive to mechanical stress or where the equipment operating environment has adverse factors such as vibration and impact, further ensuring the long-term stable operation of magnetic switches.

[0066] Furthermore, as a preferred embodiment of this utility model and not a limitation, the length P of the engaging member is greater than the thickness Q of the housing, so that the engaging member can extend fully to the outside of the housing in the assembled state and form an effective engaging connection with the mounting opening on the equipment. This ensures that the engaging member has sufficient length to achieve a stable fit with the external structure, avoiding problems such as insecure fixing, easy loosening, or improper assembly caused by the engaging member being too short. This improves the connection strength and reliability between the magnetic switch protection component and the equipment, ensuring that a stable installation state can still be maintained under vibration, pulling, or long-term use conditions.

[0067] Specifically, the structural configuration where the length P of the locking component is greater than the thickness Q of the housing allows the locking component to have sufficient extension beyond the housing thickness to adapt to the structural requirements of different equipment mounting surfaces and the position of mounting holes. This enhances the adaptability and versatility of the magnetic switch protection component in different installation scenarios. At the same time, while ensuring the reliability of the fixing, it avoids problems such as interference with surrounding structures or affecting the overall appearance coordination caused by the excessive length of the locking component, which helps to achieve the miniaturization, compactness and aesthetic design of the product.

[0068] like Figures 1 to 10The magnetic switch protection assembly shown has a housing 1 and a locking member 3 integrally formed. Both the housing 1 and the locking member 3 are made of silicone. An opening 21 is provided on one side of the inner cavity 2 of the housing. The housing 1 is provided with a sealing element for sealing the inner cavity of the housing. The sealing element is used to seal the reed switch in the inner cavity 2 of the housing. The sealing element is made of one of epoxy resin, polyurethane, silicone rubber or organosilicon material.

[0069] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, by using an integral molding process to manufacture the housing and the locking component, problems such as assembly errors, connection gaps, or structural looseness existing in traditional split structures are avoided. This results in a complete, continuous, and robust overall structure between the housing and the locking component, which not only improves the overall structural strength and durability of the component but also ensures the precise and reliable relative position of the locking component and the inner cavity of the housing. This enhances the stability and consistency of the magnetic switch protection component during assembly and use, and is conducive to improving the overall quality and reliability of the product.

[0070] Specifically, both the housing and the locking component are made of silicone. Silicone has excellent elasticity, flexibility, and resistance to compression deformation, which allows the locking component to produce appropriate elastic deformation when it mates with the opening of the external equipment, facilitating assembly, insertion, and secure locking. At the same time, it can maintain good resilience during long-term use, preventing fixation failure caused by repeated assembly or environmental stress. In addition, silicone also has excellent high and low temperature resistance, aging resistance, and weather resistance, which can adapt to a wide operating temperature range and complex operating environments, improving the environmental adaptability and service life of the magnetic switch protection component.

[0071] In addition, the housing and the snap-fit ​​parts are manufactured as a whole through a one-piece molding process, eliminating the need for subsequent assembly or bonding operations. This not only simplifies the production process and reduces manufacturing difficulty, but also reduces the number of parts and assembly steps, which helps to improve production efficiency, reduce production costs, and effectively ensure product consistency.

[0072] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the sealing element is used to seal the reed switch in the inner cavity of the housing. It is made of one of epoxy resin, polyurethane, silicone rubber or organosilicon materials, which prevents external mechanical stress and vibration from directly interfering with the magnetic switch. These materials have excellent sealing, insulation, temperature resistance and chemical stability, and can effectively block external environmental factors such as moisture, dust and corrosive gases from damaging the magnetic switch, ensuring the stable operation of sensitive elements such as reed switches in various complex environments.

[0073] like Figures 1 to 10 The magnetic control device shown includes the magnetic control switch protection assembly as described above and the magnetic control switch located in the inner cavity 2 of the housing.

[0074] Specifically, by embedding the magnetic switch inside the housing cavity and encapsulating and fixing it using the magnetic switch protection assembly described above, which features excellent structural design, reasonable material selection, and effective fixing methods, the magnetic switch is placed in a closed, stable, and stress-isolated environment. This effectively avoids damage, malfunction, or performance degradation of the magnetic switch caused by external mechanical stress, vibration, improper assembly, or environmental changes, significantly improving the safety, reliability, and long-term stability of the magnetic switch.

[0075] Optionally, in some embodiments, the magnetic switch may be a Hall element type magnetic switch or a reed switch type magnetic switch.

[0076] Optionally, in some embodiments, a seal is provided inside the housing cavity for securing and sealing the magnetic switch.

[0077] The device includes the magnetic control device as described above.

[0078] Optionally, in some embodiments, the device can be a CNC machining device or a heating device. Specifically, the device is a kitchen and bathroom heating device such as an oven or a disinfection cabinet. The magnetic control device has good temperature resistance and stability, which can meet the requirements of the device's usage scenarios.

[0079] Because the equipment needs to be lightweight and thin, the plate at the connection point with the magnetic control device is thin. If it is tightened with screws, it cannot be effectively fixed. Instead, it is easy to cause deformation of the thin plate with low structural strength during the fixing process.

[0080] Specifically, the device in this utility model uses the magnetic control device described above, which is installed using tool-free and low-stress fixing methods such as elastic snap-fit. It eliminates the need for complex assembly methods such as traditional screw fastening, making the installation process of the magnetic control device in the device simpler and faster, reducing the difficulty of equipment assembly and operation requirements, and helping to improve the overall assembly efficiency of the equipment and reduce production costs. At the same time, the magnetic control device is easy to disassemble and replace, which facilitates later maintenance, repair or functional upgrades, and improves the serviceability and maintenance convenience of the equipment during use.

[0081] Example 1 like Figures 1 to 10 The illustrated magnetic switch protection assembly includes a housing 1. The housing 1 has an inner cavity 2 for accommodating the magnetic switch and a locking member 3. The locking member 3 is connected to the surface of the housing 1. The locking member 3 is partially or entirely made of a deformable elastic material and has a limiting end 31 that engages with an external opening for positioning. The locking part 3 is integrally formed on the surface of the housing. The magnetic switch is a reed switch type magnetic switch.

[0082] This invention uses a locking member 3 made of deformable elastic material on the surface of the housing 1, and uses the locking member 3 to limit the engagement with the opening of the external device to fix the housing 1. This replaces the mechanical fixing method of screw tightening in the traditional technology, and avoids the assembly stress generated when the bolt is tightened from being transmitted to the inner cavity of the housing. This effectively reduces the risk of structural damage or performance degradation of the magnetic switch due to stress, thereby improving the safety and reliability of the magnetic switch.

[0083] Example 2 Based on Example 1, Example 2 also has the following implementation method: The engaging part 3 is detachably connected to the housing 1, and engages with the housing 1 via a snap-fit ​​connection. The magnetic switch is a Hall element type magnetic switch.

[0084] Example 3 Based on Example 1, Example 3 also has the following implementation method: The engaging component 3 includes a first connecting part 4 connected to the housing 1 and a second connecting part 5 connected to the first connecting part 4. The limiting end 31 is a groove provided in the limiting end 4 and / or the second connecting part 5.

[0085] Example 4 Based on Example 1, Example 4 also has the following implementation method: The engaging component 3 includes a first connecting part 4 connected to the housing 1 and a second connecting part 5 connected to the first connecting part 4. The limiting end 31 is a protrusion provided on the limiting end 4 and / or the second connecting part 5.

[0086] Example 5 Example 5, based on Example 4, also has the following implementation method: The maximum outer diameter of the second connecting part 5 is greater than the minimum outer diameter of the first connecting part 4.
