Description

Electromechanical switch assemblies and electrical equipment Technical Field

[0001] This application belongs to the field of electrical equipment interlocking technology, and more specifically, relates to an electromechanical linkage switch assembly and electrical equipment. Background Technology

[0002] In existing pluggable electrical devices (such as power modules, tool batteries, and functional expansion units), there are usually electrical and mechanical connections between the functional module and the main body of the device. To prevent the module from accidentally starting after being detached from the main body, thereby avoiding safety risks such as electric shock, short circuit, and mechanical movement, an "interlock" mechanism is usually designed to ensure that "the device can be turned on after insertion and must be turned off before being removed."

[0003] Traditional interlocking solutions have the following main drawbacks: Pure mechanical locking: It only achieves physical fixation. Users may forcibly pull out the module while it is not powered off, resulting in arcing, data loss or mechanical damage.

[0004] The solution combines independent electronic detection with an electronically controlled switch: the insertion status of the module is detected by a sensor, and the power supply is controlled by a controller. This solution is costly, has complex circuitry, and the interlocking mechanism fails in the event of a power outage or controller malfunction, raising concerns about its reliability.

[0005] Therefore, traditional interlocking schemes have limitations in terms of structural compactness and reliability, and pose a safety risk of accidents due to misoperation. Summary of the Invention

[0006] The purpose of this application is to provide an electromechanical linkage switch assembly and electrical equipment, which aims to solve the problems of traditional interlocking schemes having limited structural compactness and reliability.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: Firstly, this application provides an electromechanical linkage switch assembly disposed between a device body and a functional module. The functional module is pluggably adapted to the device body, with the pull-out direction of the functional module as the first direction. The electromechanical linkage switch assembly includes: a male connector unit connected to the device body; a female connector unit including a rotating base fixed to the functional module, and a second limiter slidably adapted to the rotating base along the pull-out direction of the functional module, the second limiter also being rotatable within the rotating base; the sidewall of the rotating base forms an adjustment channel and a trigger channel sequentially connected along the first direction, the adjustment channel extending along the first direction, and the trigger channel extending circumferentially along the rotating base; the circumferential sidewall of the second limiter is provided with a trigger element, and the second limiter faces the first direction. The device comprises a main body limiting groove, and an adjusting member formed on the side of the second limiter facing away from the first direction; a switch unit having a switch portion; the male connector unit can push the second limiter along the first direction to move the trigger member along the adjusting channel to the connecting end of the trigger channel, and to extend the adjusting member out of the rotating seat; the adjusting member extending out of the rotating seat can drive the trigger member to move along the trigger channel to control the function module to switch to the working state by triggering the switch portion, and can also cause the free end of the male connector unit to be engaged in the main body limiting groove to limit the displacement of the male connector unit in the insertion and removal direction of the function module; or, the adjusting member extending out of the rotating seat can drive the trigger member to move along the trigger channel to control the function module to switch to the power-off state by moving away from the switch portion, and can also cause the free end of the male connector unit to disengage from the main body limiting groove.

[0008] The solution shown in this application embodiment has the following advantages compared with the prior art: First, through the path design of "adjustment channel → trigger channel", when the functional module is inserted, the second limiter must first move into place along the second direction (i.e., the insertion direction of the functional module) to push out the adjustment member before the switch can be triggered by rotating the adjustment member. This ensures from a physical structure perspective that the machine can only be turned on after full insertion.

[0009] The removal process is the opposite. First, the second limiter must be rotated in the opposite direction to the starting point of the trigger channel via the adjusting component. This releases the triggered state of the switch, shuts down the functional module, and allows the male connector unit to disengage from the main body limit slot, thus enabling the functional module to be pulled out axially. This achieves the goal of requiring the module to be powered off before removal, preventing hot-plugging.

[0010] Secondly, the insertion / removal motion, rotational triggering motion, mechanical locking function, and microswitch triggering are integrated into the female connector unit, making the female connector unit compact in structure and highly space-efficient, suitable for pluggable products with size requirements. Furthermore, all interlocking logic is implemented by a mechanical structure, independent of easily interfered position detection, distance detection, and other signal detection paths, resulting in strong anti-interference capabilities, good environmental adaptability, and a long service life.

[0011] Thirdly, when performing plugging / unplugging and power-on / off operations, users can obtain clear operational feedback through explicit perception of changes in the adjustment process (trigger switching between different channels) and the final locking status perception (male connector snapping into the main body's limiting slot), thereby knowing the safety status of the equipment (whether it is locked or can be powered on). This eliminates the need for status sensors and dedicated control circuits for position detection, reducing material costs and assembly complexity.

[0012] In summary, this application, through the design of an electromechanical integrated channel and linkage mechanism, achieves an irreversible and safe operating logic of "insertion → power on → power off → removal" for plug-in products in a simple, reliable, and low-cost manner, thereby improving the safety and reliability of the products.

[0013] In conjunction with the first aspect, in one possible implementation, the female head unit further includes an elastic element disposed between the second limiter and the rotating seat, and configured with a preload force to move the trigger element away from the trigger channel in a second direction, wherein the second direction is the insertion direction of the functional module.

[0014] In conjunction with the first aspect, in one possible implementation, the extended end of the trigger channel is formed with a trigger limiting groove, the trigger limiting groove being located on the side of the trigger channel facing the first direction, and the main limiting groove having a first clearance groove on the side facing away from the first direction; when the switch is triggered, the free end of the male unit extends into the first clearance groove, and the triggering element is engaged in the trigger limiting groove to limit the displacement of the triggering element in the extension direction of the trigger channel.

[0015] In conjunction with the first aspect, in one possible implementation, the sidewall of the rotating seat further forms a first mounting channel and a second mounting channel sequentially connected along a first direction; the first mounting channel extends along the first direction and forms a mounting port on the side of the rotating seat facing the first direction; the second mounting channel extends circumferentially along the rotating seat and its extended end connects to the end of the adjustment channel facing the first direction.

[0016] In some embodiments, an anti-detachment groove is formed at the extended end of the second mounting channel, the anti-detachment groove being located on the side of the second mounting channel facing the first direction, and the trigger can be engaged in the anti-detachment groove to limit the displacement of the trigger in the extending direction of the second mounting channel.

[0017] In conjunction with the first aspect, in one possible implementation, the male connector unit includes a first limiter extending along a first direction, the free end of the first limiter having a limiting member extending in a direction perpendicular to the first direction; the limiting member can engage with the main body limiting groove to limit the displacement of the male connector unit in the insertion / removal direction of the functional module.

[0018] In some embodiments, the second limiter also forms a plug-in channel on the side facing the insertion direction of the functional module. The plug-in channel extends along a first direction, and the plug-in channel and the main body limiting groove are sequentially connected along the first direction. In the extension direction of the limiting member, the length of the plug-in channel is greater than the length of the limiting member. In a third direction, the width of the plug-in channel is greater than the width of the limiting member. The third direction is perpendicular to both the first direction and the extension direction of the limiting member.

[0019] In some embodiments, the first limiter includes a limiter body and a plug-in body sequentially connected along a first direction. The outer periphery of the plug-in body is located within the outer periphery of the limiter body. In a third direction, the width of the plug-in channel is smaller than the width of the limiter body. The limiting member is disposed at the free end of the plug-in body, and the end face of the extended end of the limiting member protrudes beyond the corresponding end face of the plug-in body. A second clearance groove is formed between the limiting member and the limiter body. The second clearance groove is used to accommodate the wall plate on the corresponding side of the limiting groove of the body when the trigger member gradually moves towards the extended end of the trigger channel.

[0020] In some embodiments, the male connector unit further includes a guide pin, and the female connector unit has a guide hole. The guide pin engages with the guide hole to correct the position of the first limiter and the limit member on a plane perpendicular to the first direction.

[0021] Secondly, embodiments of this application also provide an electrical device, including the electromechanical linkage switch assembly described above.

[0022] The solution described in this application, compared to existing technologies, achieves strict interlocking of operating sequences by employing the aforementioned electromechanical linkage switch assembly, thereby enhancing overall safety. The device requires that functional modules be fully inserted and mechanically locked before being powered on via a rotation trigger action; conversely, the module can only be unlocked and removed after the device is powered off. This effectively avoids the risks of hot-plugging and the potential for power-on without proper positioning. Furthermore, it effectively reduces costs and failure rates, and its clear mechanical feedback optimizes the user's operating feel and safety perception. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0027] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a few" means two or more, unless otherwise explicitly specified.

[0029] Please refer to Figures 1 to 12 together. The electromechanical switch assembly provided in this application will now be described. The electromechanical switch assembly is located between the main body of the equipment and the functional module. The functional module is pluggable and adaptable to the main body of the equipment. With the direction of the functional module being pulled out as the first direction, the electromechanical switch assembly includes a male connector unit 100, a female connector unit 200 and a switch unit 300.

[0030] The male connector unit 100 is connected to the main body of the device. The female connector unit 200 includes a rotating base 210 fixed to the functional module, and a second limiter 220 that is slidably adapted to the rotating base 210 along the insertion / removal direction of the functional module. The second limiter 220 can also rotate within the rotating base 210. The switch unit 300 has a switch section 301.

[0031] The sidewall of the rotating base 210 has an adjustment channel 2101 and a trigger channel 2102 connected sequentially along the first direction. The adjustment channel 2101 extends along the first direction, and the trigger channel 2102 extends along the circumference of the rotating base 210. The circumferential sidewall of the second limiter 220 is provided with a trigger element 221. The side of the second limiter 220 facing the first direction has a main body limiting groove 2201, and the side of the second limiter 220 facing away from the first direction has an adjustment element 222.

[0032] The male unit 100 can push the second limiter 220 along the first direction, so that the trigger 221 moves along the adjustment channel 2101 to the connecting end of the trigger channel 2102, and the adjustment 222 extends out of the rotating seat 210.

[0033] The adjusting member 222 extending from the rotating base 210 can drive the trigger member 221 to move along the trigger channel 2102, so as to control the function module to switch to the working state through the trigger switch 301. It can also make the free end of the male connector 100 engage with the main body limiting groove 2201, so as to limit the displacement of the male connector 100 in the insertion and removal direction of the function module.

[0034] Furthermore, the adjusting member 222 extending from the rotating seat 210 can drive the trigger member 221 to move along the trigger channel 2102, so as to switch the control function module to the off state by moving away from the switch part 301, and can also make the free end of the male head unit 100 disengage from the main body limiting groove 2201.

[0035] In this embodiment, the female connector unit 200 is disposed on the front of the functional module, and the male connector unit 100 is disposed on the side of the plug-in installation space of the device body.

[0036] In this embodiment, the switch unit 300 is electrically connected to the functional module. After the switch part 301 of the switch unit 300 is triggered, the switch unit 300 sends a positioning signal to the functional module, and the functional module then triggers the working state and is ready to be powered on at any time.

[0037] The electromechanical linkage switch assembly provided in this application has the following advantages compared with the prior art: First, through the path design of "adjustment channel 2101 → trigger channel 2102", when the functional module is inserted, the second limiter 220 must first move into place along the second direction (i.e., the insertion direction of the functional module) to push out the adjustment member 222 before the switch part 301 can be triggered by rotating the adjustment member 222. This ensures from a physical structure perspective that the machine can only be turned on after full insertion.

[0038] The unplugging process is the opposite. First, the second limiter 220 must be rotated in the opposite direction to the starting point of the trigger channel 2102 via the adjusting member 222. The switch 301 is then deactivated, the functional module is powered off, and only then can the male connector unit 100 be disengaged from the main body limiting groove 2201, allowing the functional module to be pulled out axially. This achieves the goal of requiring the module to be powered off before unplugging, preventing hot-plugging.

[0039] Secondly, the insertion / removal motion, rotational triggering motion, mechanical locking function, and microswitch triggering are integrated into the female connector unit 200, making the female connector unit 200 compact in structure and highly space-efficient, suitable for pluggable products with size requirements. Furthermore, all interlocking logic is implemented by a mechanical structure, independent of easily interfered position detection, distance detection, and other signal detection paths, resulting in strong anti-interference capabilities, good environmental adaptability, and a long service life.

[0040] Thirdly, when performing insertion, removal, and power-on / off operations, users can obtain clear operational feedback through explicit perception of changes in the adjustment process (trigger 221 switching between different channels) and the final locking status perception (male connector 100 snapping into the main body limiting slot 2201), thereby knowing the safety status of the equipment (whether it is locked or can be powered on). This eliminates the need for status sensors and dedicated control circuits for position detection, reducing material costs and assembly complexity.

[0041] In summary, this application, through the design of an electromechanical integrated channel and linkage mechanism, achieves an irreversible and safe operating logic of "insertion → power on → power off → removal" for plug-in products in a simple, reliable, and low-cost manner, thereby improving the safety and reliability of the products.

[0042] In some embodiments, the switch portion 301 is disposed corresponding to the extension end of the trigger channel 2102, and the trigger member 221 is a straight rod-shaped member, as shown in Figures 3 to 5 and Figures 7 to 12. Alternatively, the trigger member 221 is an L-shaped rod, and in the first direction, the switch portion 301 is offset from the extension end of the trigger channel 2102, such that the end of the trigger member 221 can touch the switch portion 301.

[0043] In some embodiments, referring to Figures 3, 7 and 8, the female head unit 200 further includes an elastic element 230, which is disposed between the second limiter 220 and the rotating seat 210 and is configured with a preload force to cause the trigger 221 to move away from the trigger channel 2102 in a second direction, wherein the second direction is the insertion direction of the functional module.

[0044] When the functional module is removed, the preload of the elastic element 230 automatically drives the second limiter 220 to reset in the second direction (insertion direction). This causes the trigger element 221 to automatically retract from the connecting end of the trigger channel 2102 to the starting end of the adjustment channel 2101, preparing for the next insertion operation. This automatic reset mechanism eliminates the tedious steps of manual reset, ensuring the continuity and reliability of the "insertion-power-power-remove" operation cycle.

[0045] The preload provided by the elastic element 230 also ensures that the trigger element 221 is stably located within the adjustment channel 2101 and away from the trigger channel 2102 under normal conditions (when the functional module is not inserted). This effectively prevents the risk of the second limiter 220 moving due to vibration or accidental contact, thereby accidentally triggering the switch 301. Even if an accidental contact occurs without the functional module installed, the trigger element 221 will be pushed back to a safe position by the elastic force, avoiding the safety hazards of loose connection or accidental triggering of the main body of the equipment when the functional module is not installed.

[0046] Furthermore, automatic reset and position holding are achieved through mechanical elasticity, eliminating the need for additional sensors or control logic to detect the status. This further simplifies circuit design and control procedures, which helps reduce manufacturing costs and failure rates.

[0047] The implementation of the elastic element 230 in this embodiment is illustrated as follows: 1) The elastic element 230 is a compression spring, which is sleeved on the outer periphery of the second limiter 220, and its two ends abut against the second limiter 220 and the rotating seat 210 respectively.

[0048] 2) The elastic element 230 is a compression spring. The rotating seat 210 has a guide hole 201 inside, and the opposite end of the second limiter 220 has a corresponding guide rod. The compression spring is sleeved on the guide rod, and its two ends abut against the end face of the second limiter 220 and the end face of the guide hole 201, respectively.

[0049] The two implementation methods described above mainly provide axial reset force. When the functional module is pulled out, the compression spring pushes the second limiter 220 to move axially outward, causing the trigger 221 to exit along the adjustment channel 2101, while the adjustment member 222 retracts into the rotating seat 210. During insertion, the male unit 100 needs to overcome the resistance of the compression spring to push the second limiter 220 inward, so that the trigger 221 reaches the end of the adjustment channel 2101.

[0050] 3) The elastic element 230 is integrally formed with the second limiter 220 or the rotating seat 210, employing a flexible cantilever beam structure (elastic arm). For example, the side wall of the second limiter 220 is partially hollowed out and extends outwards to form an elastic arm, the free end of which abuts against a pre-set protrusion on the inner wall of the rotating seat 210. Alternatively, the inner wall of the rotating seat 210 is integrally formed with an inwardly extending elastic claw, which abuts against the stepped surface of the second limiter 220. This reduces the number of independent elastic elements 230, resulting in a more compact structure, which is beneficial for miniaturization of the assembly and reduces assembly costs.

[0051] In some embodiments, referring to Figures 7, 9, 10 and 11, the extended end of the trigger channel 2102 is formed with a trigger limiting groove 2107, the trigger limiting groove 2107 is located on the side of the trigger channel 2102 facing the first direction, and the main limiting groove 2201 is provided with a first clearance groove 2204 on the side facing away from the first direction.

[0052] When the trigger switch 301 is in the state, the free end of the male connector 100 extends into the first clearance groove 2204, and the trigger member 221 is engaged in the trigger limiting groove 2107 to limit the displacement of the trigger member 221 in the extension direction of the trigger channel 2102, as shown in FIG12.

[0053] This embodiment is applicable to both scenarios with and without elastic components.

[0054] 1) When the elastic element 230 is inserted, the male unit 100 pushes the second limiter 220 forward against the elastic force, causing the trigger element 221 to move through the adjustment channel 2101 to the starting point of the trigger channel 2102. At the same time, the limiter 120 and the first clearance groove are in the state shown in Figure 9. Rotating the adjustment element 222, the trigger element 221 moves along the trigger channel 2102 until the trigger element 221 moves to the position corresponding to the trigger limit groove 2107, and the switch 301 is triggered. At this time, the pulling force on the adjustment element 222 is released. Under the action of the elastic element 230, the second limiter 220 moves as a whole in the insertion direction of the functional module, and the trigger element 221 is inserted into the trigger limit groove 2107. At the same time, the free end of the male unit 100 extends into the first clearance groove 2204, as shown in Figure 12.

[0055] When pulling out, first pull the adjusting member 222 along the first direction to disengage the trigger member 221 from the trigger limiting groove 2107. At the same time, the free end of the male connector unit 100 disengages from the first clearance groove 2204. Then, rotate the second limiter 220 in the opposite direction to make the trigger member 221 return to the starting point along the trigger channel 2102. Pull out the functional module, the male connector unit 100 disengages from the main body limiting groove 2201, and the elastic member 230 pushes the second limiter 220 to reset.

[0056] 2) During the insertion of the non-elastic member 230, after the trigger member 221 moves to the position corresponding to the trigger limit groove 2107, the adjusting member 222 is manually pushed in the insertion direction of the functional module, so that the second limiter 220 moves in the insertion direction of the functional module as a whole, the trigger member 221 is inserted into the trigger limit groove 2107, and at the same time the free end of the male head unit 100 extends into the first clearance groove 2204.

[0057] After the functional module is removed, the second limiter 220 needs to be manually pushed to move along the insertion direction of the functional module until it returns to its initial position.

[0058] In operation, the trigger element 221 engages with the trigger limit groove 2107, effectively preventing accidental shutdown due to vibration or accidental activation. When removing the module, the trigger element 221 must first disengage from the trigger limit groove 2107 before rotating to shut down, and then the functional module can be removed. This mechanical structure adheres to the safety logic of shutting down before removing the module, avoiding the risk of live plugging and unplugging. The first clearance groove 2204 provides clearance space for the axial movement of the trigger element 221 as it engages with the trigger limit groove 2107, ensuring a secure and unobstructed connection.

[0059] In some embodiments, referring to Figures 1 to 4, the sidewall of the rotary base 210 is further formed with a first mounting channel 2103 and a second mounting channel 2104 sequentially connected along a first direction. The first mounting channel 2103 extends along the first direction and forms a mounting port 2105 on the side of the rotary base 210 facing the first direction. The second mounting channel 2104 extends circumferentially along the rotary base 210, and its extended end connects to the end of the adjustment channel 2101 facing the first direction.

[0060] During assembly, while inserting the second limiter 220 into the rotating base 210, the trigger 221 is aligned with the mounting port 2105 and enters the first mounting channel 2103. As the second limiter 220 is inserted, the trigger 221 moves along the first mounting channel 2103 to the connecting end of the second mounting channel 2104. Subsequently, the second limiter 220 is rotated, causing the trigger 221 to move along the second mounting channel 2104 to the starting end of the adjustment channel 2101 (i.e., the end facing the first direction). At this point, the assembly between the second limiter 220 and the rotating base 210 is complete.

[0061] The addition of a first mounting channel 2103 and a second mounting channel 2104 provides dedicated paths for the assembly and disassembly of the trigger element 221. During manufacturing or maintenance, the trigger element 221 can enter axially along the first mounting channel 2103 via the mounting port 2105, and then rotate to the starting point of the adjustment channel 2101 via the second mounting channel 2104, achieving rapid and precise installation and avoiding damage to parts caused by forced assembly. This structure does not interfere with normal insertion and removal operations, improving assembly efficiency and maintainability. Simultaneously, the compact channel layout fully utilizes the side wall space of the rotating base 210, further optimizing the overall structural integration and reducing production costs.

[0062] In one specific embodiment, the second mounting channel 2104 and the trigger channel 2102 are located on opposite sides of the adjustment channel 2101. During assembly, the trigger element 221 enters the adjustment channel 2101 via the first mounting channel 2103 and the second mounting channel 2104; during operation, it moves along the opposite trigger channel 2102. This separates the mounting path from the working path, preventing the mounting channel from being mistakenly used as the trigger path and ensuring that rotation is only possible along the trigger channel 2102 during operation, thus preventing accidental shutdown or unlocking due to misoperation.

[0063] In another specific embodiment, the second mounting channel 2104 and the trigger channel 2102 are both located on the same side of the adjustment channel 2101, and the second mounting channel 2104 and the trigger channel 2102 are distributed along the first direction.

[0064] This concentrates the installation and working paths on the same side, resulting in a more compact structural layout and saving circumferential space. During assembly, the trigger element 221 enters the starting point of the adjustment channel 2101 via the first installation channel 2103 and the second installation channel 2104. It can then move a short distance within the adjustment channel 2101 to enter the trigger channel 2102, resulting in a short operation path and smooth transition.

[0065] In some embodiments, referring to FIG4, an anti-detachment groove 2106 is formed at the extended end of the second mounting channel 2104. The anti-detachment groove 2106 is located on the side of the second mounting channel 2104 facing the first direction. The trigger 221 can be engaged in the anti-detachment groove 2106 to limit the displacement of the trigger 221 in the extending direction of the second mounting channel 2104.

[0066] When the functional module is ready for use, the male unit 100 pushes the second limiter 220 to move, causing the trigger 221 to disengage from the anti-disengagement groove 2106. Then, the adjustable member 222 can be rotated to allow the trigger 221 to enter the adjustment channel 2101 and complete the subsequent power-on operation. The anti-disengagement groove 2106 provides a positioning structure for the assembly and temporary fixation of the trigger 221, improving assembly efficiency and transportation safety. During assembly, after the trigger 221 enters axially through the first installation channel 2103, it rotates along the second installation channel 2104 to its end, where it can be easily inserted into the anti-disengagement groove 2106, achieving pre-installation positioning. This prevents it from accidentally slipping or shifting due to vibration during subsequent assembly or transportation, simplifying the assembly process and reducing operational difficulty.

[0067] The above-mentioned scheme of setting the anti-disengagement groove 2106 and the scheme of setting the elastic element 230 can be used simultaneously. During assembly, the preload of the elastic element 230 will naturally press the trigger 221 into the anti-disengagement groove 2106, and it can be stably positioned without additional operation, preventing loosening during transportation or assembly. During operation, the trigger 221 needs to actively overcome the elastic force to disengage from the anti-disengagement groove 2106 before it can enter the adjustment channel 2101. This not only enhances the ability to prevent accidental activation, but also ensures the reliability of the trigger 221's reset in the working state through the elastic force.

[0068] In specific implementation, an anti-detachment protrusion is provided on the side wall of the extended end of the second mounting channel 2104 (as shown in Figure 4), and an anti-detachment groove 2106 is formed between the anti-detachment protrusion and the side wall of the adjustment channel 2101. In the first direction, the width of the second mounting channel 2104 is greater than the width of the trigger member 221. If the anti-detachment protrusion is a rigid member, the distance between the anti-detachment protrusion and the opposite side wall of the second mounting channel 2104 is slightly greater than the width of the trigger member 221; if the anti-detachment protrusion is an elastic member 230, the distance between the anti-detachment protrusion and the opposite side wall of the second mounting channel 2104 is less than the width of the trigger member 221. When the trigger member 221 crosses the anti-detachment protrusion, the anti-detachment protrusion is deformed by pressure, and returns to its original state after crossing.

[0069] In some embodiments, referring to Figures 1 to 4 and Figure 11, the male connector unit 100 includes a first limiter 110 extending along a first direction, and the free end of the first limiter 110 is provided with a limiting member 120 extending in a direction perpendicular to the first direction. The limiting member 120 can engage with the main body limiting groove 2201 to limit the displacement of the male connector unit 100 in the insertion and removal direction of the functional module.

[0070] The limiting member 120 and the main limiting groove 2201 form a T-shaped or L-shaped mechanical fastening, which increases the axial contact area and tensile strength, ensuring a stable connection even under impact or vibration, and enhancing the reliability of axial locking. Secondly, since the limiting member 120 provides reliable axial limiting, the main limiting groove 2201 of the female head unit 200 does not need to be designed with a complex self-locking structure, simplifying the processing difficulty of the rotary seat 210 and the second limiting device 220, and reducing mold costs and assembly accuracy requirements.

[0071] Optionally, the first limiter 110 and the limiter 120 may be made of metal (e.g., aluminum alloy, stainless steel) or high-strength engineering plastic (e.g., polyetheretherketone, polyimide), and the two are integrally molded to avoid forming a seam that would affect the overall axial load-bearing performance of the male head unit 100.

[0072] In some specific embodiments, referring to Figures 8 and 11, the second limiter 220 also has a plug-in channel 2202 formed on the side facing the insertion direction of the functional module, and the plug-in channel 2202 extends along the first direction. In the extension direction of the limiter 120, the length of the plug-in channel 2202 is greater than the length of the limiter 120. In the third direction, the width of the plug-in channel 2202 is greater than the width of the limiter 120, wherein the third direction is perpendicular to both the first direction and the extension direction of the limiter 120.

[0073] An insertion / removal channel 2202 extending along the first direction is added to the second limiter 220, and sufficient axial and circumferential movement space is reserved for the limiter 120, which improves the smoothness and fault tolerance of the insertion / removal operation, compensates for manufacturing and assembly tolerances, and enhances the process adaptability of the structure. At the same time, the setting of the insertion / removal channel 2202 also extends the axial length of the main body of the second limiter 220, which helps to enhance the overall structural strength of the second limiter 220.

[0074] In some specific embodiments of the first limiter 110, referring to Figures 1 to 4 and Figure 11, the first limiter 110 includes a limiter body 111 and a plug-in body 112 sequentially connected along a first direction. The outer periphery of the plug-in body 112 is located within the outer periphery of the limiter body 111. In the third direction, the width of the plug-in channel 2202 is smaller than the width of the limiter body 111. A limiting member 120 is disposed at the free end of the plug-in body 112, and the end face of the extended end of the limiting member 120 protrudes beyond the corresponding end face of the plug-in body 112. A second clearance groove 1101 is formed between the limiting member 120 and the limiter body 111. The second clearance groove 1101 is used to accommodate the wall plate on the corresponding side of the body limiting groove 2201 when the trigger member 221 gradually moves towards the extended end of the trigger channel 2102.

[0075] After the male connector 100 extends into the main body limiting groove 2201, the limiting member 120 gradually approaches the side of the main body limiting groove 2201 facing away from the first direction. After the limiting member 120 enters the main body limiting groove 2201, the limiting device body 111 abuts against the opening end face of the insertion channel 2202 facing the first direction, and then the limiting device body 111 continues to push the second limiting device 220 to move.

[0076] During insertion, because the width of the insertion / removal channel 2202 is smaller than that of the limiter body 111, the thinner insertion / removal body 112 enters the channel first to guide the limiter 120, while the thicker limiter body 111 is blocked at the opening end face of the channel. Only after the limiter 120 has fully entered the main body limiter groove 2201 does the limiter body 111 abut against the opening end face and continue to push the second limiter 220 to move axially. This design achieves a step-by-step action of "first guiding alignment, then transmitting thrust", avoiding deformation of the limiter 120 when it is not aligned, while ensuring that the limiter 120 is accurately engaged in the main body limiter groove 2201.

[0077] When the trigger 221 moves along the trigger channel 2102, the second clearance groove 1101 provides a receiving space for the side wall of the main body limiting groove 2201, preventing mechanical interference and making the rotation smooth.

[0078] Referring to Figures 1 to 5, 7 to 9, 10, and 12, in some specific embodiments of the rotary seat 210, the rotary seat 210 includes a main seat body 211 and a fixed seat body 212, with a second limiter 220 disposed within the main seat body 211. An assembly through-hole 2401 is provided on the integrated housing 240. One end of the main seat body 211 passes through the assembly through-hole 2401 and extends out of the integrated housing 240, with external threads on the extended end. The fixed seat body 212 is screwed onto the external threads of the extended end from the outside of the integrated housing 240. The fixed seat body 212 engages with the assembly step 213 on the main seat body 211, clamping and fixing it from both sides of the assembly through-hole 2401. An adjusting member 222 extends out of the fixed seat body 212, allowing the operator to rotate the adjusting member 222.

[0079] By splitting the rotary base 210 into a main base 211 and a fixed base 212, and employing an internal and external clamping installation method, the assembly convenience and structural stability of the assembly are improved. The main base 211 passes through the assembly through-hole 2401 from the inside of the integrated housing 240, and its protruding end is threaded into the external fixed base 212. This, combined with the assembly step 213, clamps the housing wall from both sides, achieving secure positioning without additional fasteners, simplifying the assembly process and reducing production costs. This split design allows the main base 211 and the fixed base 212 to be manufactured using different materials or processes. For example, the main base 211 can be made of wear-resistant materials (such as PTFE) to ensure sliding fit accuracy, while the fixed base 212 can use standard parts (such as aluminum alloy components) to control costs. Simultaneously, the fixed base 212 is located on the outside of the integrated housing 240, not occupying internal space, which is beneficial for product miniaturization. During maintenance, the internal components can be removed simply by detaching the fixed base 212 from the outside, improving maintainability. In addition, the internal and external clamping structure effectively resists the axial tension and rotational torque generated during insertion and removal operations, ensuring the reliability of the connection between the rotating seat 210 and the housing during long-term use.

[0080] Optionally, as shown in Figures 1, 2, 4, 5, and 7, the fixed base 212 is provided with a base orientation mark, and the adjusting component 222 is provided with a turning orientation mark 223. During operation, the user only needs to align the two marks or refer to their relative positions to accurately determine the current rotation direction and switch status, avoiding the inability to start or accidental shutdown due to incorrect direction. At the same time, the marks provide a clear positional reference for assembly and maintenance, ensuring that the second limiter 220 is installed in the correct starting position, improving the assembly's error prevention capability and ease of use.

[0081] In this embodiment, the screw pointing mark 223 can be implemented in ways including, but not limited to, arrow patterns, raised arrow textures, etc. The seat pointing mark includes, but is not limited to, a flat surface on the outer periphery of the fixed seat 212, a position indicator pattern on the axial end face of the fixed seat 212, raised textures, etc.

[0082] In some embodiments, referring to Figures 1 to 3, the male connector 100 further includes a guide pin 130, and the female connector 200 has a guide hole 201. The guide pin 130 cooperates with the guide hole 201 to correct the position of the first limiter 110 and the limiter 120 on a plane perpendicular to the first direction. Optionally, the free end of the guide pin is provided with a guide cone surface.

[0083] During insertion, the guide pin 130 preferentially enters the guide hole 201, and guides the male head unit 100 through a tapered surface or chamfer to automatically correct radial and circumferential deviations, ensuring that the limiting member 120 can accurately align with the insertion / removal channel 2202. This avoids jamming, misalignment, or even structural damage caused by blind insertion or assembly tolerances, and also provides a stable initial position reference for the trigger member 221 to enter the trigger channel 2102, ensuring the accuracy of subsequent rotation and start-up actions. This reduces the requirements for user operating precision, making the insertion / removal process smoother, and is suitable for installation scenarios with limited space or where visual alignment is not possible. In addition, the guide pin 130 can withstand lateral loads and vibration impacts in the inserted state, effectively distributing the force between the limiting member 120 and the main body limiting groove 2201, preventing excessive wear or deformation of the limiting member 120, and extending the mechanical life.

[0084] In some embodiments, referring to Figures 1 to 3, the female connector unit 200 further includes an integrated housing 240 fixedly connected to the functional module. The integrated housing 240 has clearance holes for the first limiter 110 and the limit member 120 to pass through. The female connector unit 200 and the switch unit 300 are both disposed within the integrated housing 240. The integrated housing 240 is connected and fixed to the housing of the functional module by means of snap-fit, threaded fasteners, or other methods.

[0085] The integrated housing 240 provides a physical barrier for the internal structure and electrical components, effectively preventing damage or short circuits caused by dust, foreign objects, or accidental contact, thus enhancing environmental adaptability and electrical safety performance. Simultaneously, integrating the female connector unit 200 and the switch unit 300 into the same housing forms an independent functional module. This module can be pre-assembled and tested before being installed as a whole, simplifying the assembly process and reducing production errors. Furthermore, the integrated housing 240 can employ a sealed design to further meet waterproof and dustproof requirements, making it suitable for harsh environments such as outdoor or industrial settings. When maintenance is required, only the integrated housing 240 needs to be disassembled for inspection of internal components without disturbing other parts of the functional module, improving maintainability.

[0086] Optionally, an opening is provided on one side of the integrated unit to facilitate the disassembly and maintenance of components such as the female head unit 200 and the switch unit 300.

[0087] Optionally, the integrated housing 240 may include, but is not limited to, engineering plastic components (e.g., ABS, PC), metal components (e.g., aluminum alloy, stainless steel), and composite material components (e.g., carbon fiber reinforced plastic, glass fiber reinforced nylon).

[0088] In some embodiments, referring to Figures 3 to 6, the switching unit 300 includes a switching circuit board 310 and a switching body 320. The switching body 320 is provided with a switching contact plate 340, which forms a switching portion 301. During installation, the switching circuit board 310 is mounted on the functional module or integrated housing 240. The switching body 320 is a micro switch.

[0089] Optionally, the switch contact 340 uses a metal spring (such as stainless steel). One end of the metal spring is fixed to the switch body 320, and the other end is tilted upwards. The middle of the switch contact 340 is positioned directly opposite the fixed contact of the switch body 320. When the trigger 221 presses down on the tilted end of the switch contact 340, the switch contact 340 deforms under force and makes contact with the fixed contact, forming an electrical connection. When the trigger 221 is removed, the switch contact 340 returns to its initial shape due to its own elasticity, and the contact is broken.

[0090] Optionally, the switching unit 300 also includes a switching interface 330, which can be connected to a power supply unit to power the switching circuit board 310 and the switching body 320. The power supply unit can be a separate battery housed in the integrated housing 240 or integrated into the functional module. During the development or production phase, the switching interface 330 can also serve as a debugging interface for parameter setting or fault diagnosis.

[0091] The electromechanical linkage switch assembly of this application is used as follows: S100, Insertion process: S110, Align the functional module with the insertion / removal mounting space on the main body of the device and insert it in the second direction. The guide pin 130 on the male connector unit 100 first enters the guide hole 201 on the integrated housing 240 of the female connector unit 200, and the conical surface guides the pin to ensure that the limiting member 120 is accurately aligned with the entrance of the insertion / removal channel 2202. At the same time, the first limiter 110 of the male connector unit 100 begins to enter the clearance hole of the integrated housing 240.

[0092] S120, Continue insertion. The insertion / removal body 112 and its free end limiting member 120 enter the insertion / removal channel 2202 facing the insertion direction side of the second limiting device 220. The limiting member 120 can slide smoothly in the channel without precise alignment. When the limiting member 120 reaches the end of the insertion / removal channel 2202, the limiting member 120 moves into the main body limiting groove 2201. The limiting device body 111 contacts the opening end face of the insertion / removal channel 2202 and begins to push the second limiting device 220 to overcome the preload force of the elastic member 230 and move along the first direction.

[0093] As the second limiter 220 moves, the elastic element 230 is compressed, and the trigger element 221 disengages from the anti-disengagement groove 2106 and slides along the adjustment channel 2101 until it reaches the connection end between the adjustment channel 2101 and the trigger channel 2102. At this time, the adjustment element 222 has extended out of the outside of the rotating seat 210 for user operation.

[0094] S130. The user rotates the adjusting member 222 in the correct direction according to the turning direction mark 223 on the adjusting member 222 and the seat direction mark on the rotating seat 210. The adjusting member 222 drives the second limiter 220 to rotate, and the trigger member 221 moves along the trigger channel 2102. At the same time, the limiting member 120 of the male head unit 100 rotates relative to the main body limiting groove 2201.

[0095] When the trigger 221 moves to the extension end of the trigger channel 2102, the pulling force on the adjusting member 222 is released, and the trigger 221 engages in the trigger limiting groove 2107, while the limiting member 120 engages in the first clearance groove 2204, forming a circumferential lock. At the same time, the limiting member 120 fully enters the main body limiting groove 2201, forming an axial lock with the main body limiting groove 2201.

[0096] When the trigger element 221 is inserted into the trigger limit slot 2107, its end presses the switch contact plate 340 on the switch unit 300, triggering the switch body 320 to close. After the switch circuit board 310 detects the signal, it sends an allow operation command to the main body of the equipment. The main body of the equipment closes the main power circuit, and the functional module enters the working state.

[0097] S200, Pull-out process: S210, When the user needs to pull out the module, first pull out the adjusting member 222 in the first direction, so that the trigger member 221 disengages from the trigger limiting groove 2107 and the limiting member 120 disengages from the first clearance groove 2204. Then, rotate the adjusting member 222 in the opposite direction. The adjusting member 222 drives the second limiting device 220 to rotate in the opposite direction, and the trigger member 221 moves towards the starting point along the trigger channel 2102. When the trigger member 221 leaves the switch contact plate 340, the switch body 320 resets, the switch circuit board 310 detects the signal change, sends a prohibition command to the device body, the device body disconnects the main power circuit, and the functional module shuts down. At the same time, as the trigger member 221 moves towards the starting point of the trigger channel 2102, the limiting member 120 gradually releases the axial lock with the main body limiting groove 2201.

[0098] S220. When the trigger 221 returns to the connecting end of the trigger channel 2102, the limiting member 120 has completely released its axial lock with the main body limiting groove 2201. At this time, the user stops rotating the adjusting member 222 and instead pulls the functional module outward. Under the push of the elastic member 230, the second limiting device 220 automatically resets along the second direction, and the trigger 221 slides in the adjusting channel 2101 until it returns to the starting point of the adjusting channel 2101 and re-engages in the anti-disengagement groove 2106. The first limiting device 110 of the male connector unit 100 exits from the insertion / removal channel 2202, the guide pin 130 disengages from the guide hole 201, and the functional module is completely separated from the main body of the device.

[0099] If the second limiter 220 is not pushed to the end of the adjustment channel 2101 during insertion, the trigger 221 cannot enter the trigger channel 2102, the adjustment 222 cannot be rotated to the trigger position, the switch cannot be triggered, and the machine cannot be turned on if it is not inserted tightly.

[0100] If the adjusting member 222 is not rotated first to disengage the trigger member 221 from the trigger limiting groove 2107 and return to the starting point of the trigger channel 2102, the limiting member 120 of the male connector unit 100 will be stuck in the main body limiting groove 2201. Forcibly pulling it out will cause mechanical interference. From a mechanical structure perspective, the safety logic of turning off the power before pulling out should be followed to avoid plugging and unplugging while the power is on.

[0101] Even if the elastic element 230 is damaged, the functional module and the main body of the equipment remain effectively connected during operation due to the dual locking of the trigger limit groove 2107 and the main body limit groove 2201. When shutting down, the trigger element 221 needs to be manually disengaged from the groove, but the safety logic remains effective.

[0102] Based on the same inventive concept, this application also provides an electrical device, including the above-described electromechanical linkage switch assembly.

[0103] Compared with existing technologies, the electrical equipment provided in this application, by employing the aforementioned electromechanical linkage switch assembly, achieves strict interlocking of operating sequences, thereby improving overall safety. The equipment requires that functional modules be fully inserted and mechanically locked before being turned on by rotation; simultaneously, the modules can only be unlocked and removed after the equipment is turned off. This effectively avoids the risks of hot-plugging and the potential hazards of starting the machine in the wrong position. Furthermore, it effectively reduces costs and failure rates, and its clear mechanical feedback optimizes the user's operating feel and safety perception.

[0104] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
