Description

Technical Field

[0001] This invention relates to the field of toggle switch technology, specifically to an electromagnetic force-operated toggle switch. Background Technology

[0002] A toggle switch is a manual control switch mainly used for controlling the on / off state of AC / DC power circuits. It can also be used in circuits with frequencies ranging from several kilohertz to up to 1 megahertz. It features small size and easy operation. In the prior art, patent CN207068735 U discloses a novel toggle switch. A rocker arm is installed inside a copper head, with a top cover connected to the bottom of the copper head. The bottom of the top cover is fixedly connected to a housing. Terminals, rivets, and stationary contacts are installed at the bottom of the housing. The inner side of the housing contains a moving bracket, a push rod, a moving contact, and a mounting base. The moving contact is installed at one end of the moving bracket, which is also movably connected to one end of the push rod. The outer side of the push rod contacts the rocker arm. A return spring is installed inside the rocker arm. This novel toggle switch replaces the insulating plate in traditional switches with a rocker arm, solving the problem of unnecessary movement and abnormal noise caused by the moving insulating plate inside the switch. The rocker arm is fixed in position, preventing rotation and vertical displacement, thus ensuring safety and stability. With improved performance, the gap between the rocker arm and the copper head becomes controllable after the rocker arm is fixed, and the dustproof effect is improved. The arc-shaped inner wall of the rocker arm is connected to the rocker arm bracket, which has good sealing performance and beautiful appearance. When the device is used for toggle switch operation, by moving the rocker arm, the return spring causes the lower end of the push rod to contact and squeeze the upper side of the moving bracket, thereby causing the moving bracket to flip through contact and squeezing, and thus realizing the conductive contact between the moving contact and the stationary contact. However, the device achieves the toggle switch operation by sliding between the push rod and the moving bracket. The long-term sliding between the push rod and the moving bracket by spring squeezing is prone to mechanical wear, which will cause stiffness in the use of the device. Therefore, we propose an electromagnetic force holding toggle switch. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an electromagnetic force holding toggle switch. This device aims to achieve stable holding of the switch state through electromagnetic force, reduce the physical wear of traditional mechanical structures, and improve durability by combining protective design. Its core lies in using the magnetic field generated by the electromagnetic coil, in conjunction with the toggle element of the toggle switch, to achieve contactless conduction or disconnection and enhance anti-interference ability, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an electromagnetic force-operated toggle switch, comprising a housing, an upper end cover mounted on the upper side of the housing, a lower end cover mounted on the lower side of the housing, and further comprising an opening and closing mechanism and a closing mechanism; Opening and closing mechanism: It includes a connecting seat, a rotating shaft, a moving contact piece, a suspension frame, a stationary contact piece, a disconnecting seat, and an adjustment component. The connecting seats are respectively set at the front and rear ends of the bottom wall of the lower end cover. The moving contact piece is rotatably connected between the two connecting seats through the rotating shaft. The left and right ends of the bottom wall of the lower end cover are provided with suspension frames. The upper side of the right suspension frame is provided with a stationary contact piece, and the upper side of the left suspension frame is provided with a disconnecting seat. An adjustment component is provided between the upper end cover and the outer shell. Sealing mechanism: It is located on the upper side of the upper cover. The sealing mechanism is installed in conjunction with the control component. This device is designed to maintain the switch state stably through electromagnetic force, reduce the physical wear of traditional mechanical structures, and improve durability by combining protective design. Its core is to use the magnetic field generated by the electromagnetic coil, in conjunction with the toggle element of the toggle switch, to achieve contactless conduction or disconnection and enhance anti-interference ability.

[0005] Furthermore, the control component includes an iron sheet, a second rotating shaft, a toggle switch, a corner plate, and an electromagnet. The iron sheet is respectively disposed on the left and right ends of the upper side of the movable contact piece. The toggle switch is rotatably connected to the inside of the upper cover through the second rotating shaft. An electromagnet is provided at the lower end of the toggle switch through the corner plate. The input end of the electromagnet is electrically connected to the output end of an external control switch, and the toggle switch is turned on and off by electromagnetic force.

[0006] Furthermore, the sealing mechanism includes a first ring seat, a telescopic column, a spring, a second ring seat, and a sealing shell. The first ring seat is located on the upper side of the upper end cover. The second ring seat is located on the upper side of the first ring seat through longitudinally symmetrically distributed telescopic columns and springs. The springs are all movably connected to the outer ends of adjacent telescopic columns. The sealing shell is located on the upper side of the second ring seat. The inner arc wall of the sealing shell slides in contact with the outer surface of the upper end of the upper end cover. The sealing shell is installed in conjunction with the toggle handle to seal and dustproof the operating part of the electromagnetic force-held toggle switch, while simultaneously compressing and reinforcing the toggle handle's actuation position.

[0007] Furthermore, the sealing mechanism also includes a rubber sealing ring, which is disposed on the inner arc wall of the casing to seal the gap between the inner casing of the electromagnetic force holding toggle switch and the upper end cover.

[0008] Furthermore, the outer side of the outer shell is provided with uniformly distributed annular buckles at both the upper and lower ends, and the outer side of the upper cover and the outer side of the lower cover are provided with uniformly distributed annular brackets. The buckles are installed in conjunction with the vertically adjacent brackets to fix the upper and lower covers inside the electromagnetic force holding toggle switch to the outer shell.

[0009] Furthermore, an upper conductive shielding cover is movably sleeved on the outer side of the upper end cover, and a lower conductive shielding cover is movably sleeved on the outer side of the lower end cover, providing electromagnetic shielding for the outer side of the electromagnetic force holding toggle switch.

[0010] Furthermore, the lower outer side of the upper conductive shield is provided with a ring-shaped, evenly distributed buckle 2, and the upper outer side of the lower conductive shield is provided with a ring-shaped, evenly distributed bracket 2. The buckle 2 is installed in conjunction with the vertically adjacent bracket 2 to install and fix the upper conductive shield and the lower conductive shield inside the electromagnetic force holding toggle switch.

[0011] Furthermore, the upper conductive shield is a copper alloy upper conductive shield, and the lower conductive shield is a copper alloy lower conductive shield. By selecting appropriate materials, the magnetic field shielding of the external electromagnetic force holding toggle switch is achieved.

[0012] Furthermore, both buckle one and buckle two are provided with guide strips in the middle, and both card seat one and card seat two are provided with guide grooves in the middle. The guide strips are installed in conjunction with the adjacent guide grooves. By engaging the guide strips with the corresponding guide grooves, the horizontal rotation between adjacent buckle one and card seat one or between buckle two and card seat two within the electromagnetic force holding toggle switch is limited.

[0013] Furthermore, an indicator arrow groove is provided on the upper outer side of the upper cover to indicate the direction of the toggle switch of the electromagnetic force-operated toggle switch.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This electromagnetic force-operated toggle switch has the following advantages: 1. When using electromagnetic force to hold a toggle switch, the magnetic field generated by the electromagnetic coil, in conjunction with the toggle switch's actuating element, enables the toggle switch to perform contactless on / off operation and maintain a stable on / off state, eliminating the need for traditional spring or snap-fit ​​structures and reducing mechanical wear.

[0015] 2. When using electromagnetic force to hold the toggle switch, the opening of the on / off operation part of the device is sealed by the sealing mechanism to prevent dust from entering the device from the gaps in this part. At the same time, the sealing element is used to elastically squeeze the device's toggle element, thereby reinforcing the position of the device's toggle element.

[0016] 3. When using electromagnetic force to hold the toggle switch, a conductive shield is wrapped around the outside of the device. The conductive shield's characteristics of reflecting and canceling electromagnetic waves are used to block the influence of external electromagnetic interference on the internal circuit of the device, while preventing the leakage of internal electromagnetic signals.

[0017] 4. When using electromagnetic force to hold the toggle switch, the device housing components are installed and fixed through the snap-fit ​​between the buckle and the card seat and the installation and cooperation between the guide strip and the guide groove, which facilitates the disassembly and maintenance of the device later.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-5This embodiment provides a technical solution: an electromagnetic force-operated toggle switch, including a housing 1, an upper end cover 2 installed on the upper side of the housing 1, a lower end cover 3 installed on the lower side of the housing 1, and annularly evenly distributed snap fasteners 6 on both the upper and lower outer sides of the housing 1. Annularly evenly distributed retaining seats 7 are provided on the lower outer side of the upper end cover 2 and the upper outer side of the lower end cover 3. The snap fasteners 6 are all fitted with vertically adjacent retaining seats 7. An upper conductive shield 8 is movably sleeved on the outer side of the upper end cover 2, and a lower conductive shield 9 is movably sleeved on the outer side of the lower end cover 3. Annularly evenly distributed snap fasteners 10 are provided on the lower outer side of the upper conductive shield 8, and annularly evenly distributed retaining seats 11 are provided on the upper outer side of the lower conductive shield 9. The snap fasteners 10 are all fitted with vertically adjacent retaining seats 7. The adjacent card slots 11 are installed together. The upper conductive shield 8 is a copper alloy upper conductive shield, and the lower conductive shield 9 is a copper alloy lower conductive shield. Guide strips 13 are provided in the middle of both the first and second buckles 10. Guide grooves are provided in the middle of both the first and second card slots 11. The guide strips 13 are installed in conjunction with the adjacent guide grooves. When using the electromagnetic force to hold the toggle switch, firstly, the upper cover 2 is vertically aligned with the outer shell 1, and then the upper cover 2 is moved vertically downwards along the upper inner part of the outer shell 1, so that the two make vertical contact with each other. During the vertical downward movement of the upper cover 2, the inclined surface on its first buckle 6 presses against the inclined surface of the card slot 7 at the upper end of the outer shell 1. The first buckle 6 on the upper cover 2 is pressed by the inclined surface to a certain extent. When the upper cover 2 comes into vertical contact with the outer shell 1, the inclined surface pressing contact between the buckle 6 on the upper cover 2 and the seat 7 at the upper end of the outer shell 1 disappears. Then, through the deformation and restoring ability of the buckle 6 on the upper cover 2, the buckle 6 on the upper cover 2 and the seat 7 at the upper end of the outer shell 1 are locked together. At the same time, the guide strip 13 on the buckle 6 and the guide groove on the corresponding seat 7 slide against each other, thus locking the two together and limiting the horizontal relative rotation of the upper cover 2 and the outer shell 1. Then, the operator fixes the lower cover 3 to the lower end of the outer shell 1 using the same principle. Then, the operator puts the upper conductive shielding cover 8 on the outside of the upper cover 2 from top to bottom and puts the lower conductive shielding cover 9 on the outside from bottom to top. The upper conductive shield 8 and the lower conductive shield 9 are installed and fixed to the outside of the lower end cover 3 by means of buckle 2 10 and bracket 2 11 according to the above principle. The upper conductive shield 8 and the lower conductive shield 9 are fixed to the outside of the device. The upper conductive shield 8 is a copper alloy upper conductive shield, and the lower conductive shield 9 is a copper alloy lower conductive shield. By wrapping the device with conductive shields, the high conductivity and magnetic permeability of copper alloy itself are used to block the influence of external electromagnetic interference on the internal circuit of the device through reflection and cancellation, and at the same time prevent the leakage of internal electromagnetic signals. The device components are fixed by buckle and bracket. The later disassembly and maintenance operations are convenient. It also includes an opening and closing mechanism 4 and a closing mechanism 5. Opening / closing mechanism 4: It includes a connecting seat 41, a rotating shaft 42, a moving contact piece 43, a suspension frame 44, a stationary contact piece 45, a disconnect seat 46, and a control component 47. The connecting seats 41 are respectively located at the front and rear ends of the bottom wall of the lower end cover 3. The moving contact piece 43 is rotatably connected between the two connecting seats 41 through the rotating shaft 42. The left and right ends of the bottom wall of the lower end cover 3 are provided with suspension frames 44. The upper side of the right suspension frame 44 is provided with a stationary contact piece 45, and the upper side of the left suspension frame 44 is provided with a disconnect seat 46. A control component 47 is provided between the upper end cover 2 and the outer shell 1. The control component 47 includes an iron plate 471, a rotating shaft 472, a toggle lever 473, a corner plate 474, and an electromagnet 475. 1. The upper cover 2 is rotatably connected to a toggle switch 473 via a pivot 472, with the toggle switch 473 having an electromagnet 475 at its lower end via a corner plate 474. The input end of the electromagnet 475 is electrically connected to the output end of an external control switch. An indicator arrow groove 12 is provided on the upper outer side of the upper cover 2. When the electromagnetic force holding toggle switch is opened and closed, the electromagnet 475 is activated by the external control switch and kept in the normally open state. The operator moves the toggle switch 473 in the direction indicated by the arrow in the indicator arrow groove 12. The upper end of the toggle switch 473 flips to the left around the axis of the pivot 472. When the toggle switch 473 is turned, the lower end of the toggle switch 474 drives the electromagnet 475 to rotate to the right. As the electromagnet 475 moves closer to the iron piece 471 on the right side around the axis of the second rotating shaft 472, the electromagnet 475 generates a magnetic field through the magnetic effect of the current. When the current passes through its internal coil, it magnetizes the iron core to enhance the magnetism. Since the distance between the iron piece 471 on the right side and the electromagnet 475 is closer than that between the iron piece 471 on the left side and the electromagnet 475, the magnetic attraction force generated by the electromagnet 475 on the iron piece 471 on the right side is much greater than that on the iron piece 471 on the left side. Therefore, this magnetic attraction force causes the moving contact 43 to flip in the opposite direction around the axis of the first rotating shaft 42. The movement causes the right end of the moving contact 43 to flip and contact the stationary contact 45, thus enabling the electromagnetic force-holding toggle switch to conduct. The magnetic force keeps the electromagnetic force-holding toggle switch in a stable conducting state. When the electromagnetic force-holding toggle switch is closed, the upper end of the toggle lever 473 is moved to the right. Through the same principle, the left end of the moving contact 43 flips and contacts the disconnect seat 46, thus enabling the electromagnetic force-holding toggle switch to disconnect. This device uses the magnetic field generated by the electromagnetic coil, in conjunction with the toggle element of the toggle switch, to achieve contactless conduction or disconnection of the toggle switch and a stable on / off state. It does not rely on traditional spring or snap-fit ​​structures, thus reducing mechanical wear. Closing mechanism 5: It is located on the upper side of the upper end cover 2. The closing mechanism 5 is installed in conjunction with the control component 47. The closing mechanism 5 includes a first ring seat 51, a telescopic column 52, a spring 53, a second ring seat 54, and a sealing shell 55. The first ring seat 51 is located on the upper side of the upper end cover 2. The second ring seat 54 is provided on the upper side of the first ring seat 51 through the longitudinally symmetrically distributed telescopic columns 52 and springs 53. The springs 53 are all movably sleeved with the outer ends of the adjacent telescopic columns 52. The sealing shell 55 is provided on the upper side of the second ring seat 54. The inner arc wall of the sealing shell 55 is in sliding contact with the upper outer side of the upper end of the upper end cover 2. The sealing shell 55 cooperates with the toggle lever 473. The sealing mechanism 5 also includes a rubber sealing ring 56, which is located on the inner arc wall of the sealing shell 55. When the operator pulls the sealing shell 55 vertically upwards, it moves vertically upwards along the outer upper end of the upper cover 2 and separates from the upper cover 2. The sealing shell 55 drives the ring seat 54 to move synchronously, stretching the telescopic end of the telescopic column 52 and the spring 53 (the spring 53 is always in a stretched state), thus exposing the upper end of the toggle handle 473. After the toggle handle 473 is adjusted, the operator releases the upward pulling force applied to the sealing shell 55, and the sealing shell 55, through the stretching and restoring elasticity of the spring 53, vertically... The device is moved downwards to reset, and the upper end of the upper cover 2 is sealed by the cover 55 to prevent external dust from entering. The rubber sealing ring 56 seals the gap between the cover 55 and the upper cover 2 through the extensibility of the rubber molecules, further improving the dustproof effect. At the same time, the top wall of the cover 55 presses against the upper end of the toggle handle 473, and the pressure between the two presses to limit the position of the toggle handle 473, further reinforcing the opening and closing position of the electromagnetic force-held toggle. After the device has been used for a period of time, the ring seat 51 is removed from the upper end of the upper cover 2. (Ring seat 1 51 is fixed to the upper end cover 2 by bolt 1), Ring seat 2 54 is removed from the lower side of the cover 55 (Ring seat 2 54 is fixed to the cover 55 by bolt 2), and then the ring seat 1 51, ring seat 2 54, and the telescopic column 52 and spring 53 between them are replaced as a whole to avoid aging of spring 53 during use. The device seals the opening of the on / off operation part to prevent dust from entering the device from the gap in this part. At the same time, the sealing element uses elastic compression on the device's actuating element to reinforce the position of the device's actuating element.

[0022] The working principle of the electromagnetic force-retaining toggle switch provided by this invention is as follows: When using the electromagnetic force-retaining toggle switch, firstly, the upper cover 2 is vertically aligned with the outer shell 1, and then the upper cover 2 is vertically moved downward along the upper inner part of the outer shell 1, so that the two make vertical contact with each other. During the vertical downward movement of the upper cover 2, the inclined surface on its own latch 6 presses against the inclined surface of the upper end of the outer shell 1. The latch 6 on the upper cover 2 undergoes a certain degree of deformation due to the pressure of the inclined surface. When the upper cover 2 makes vertical contact with the outer shell 1, the inclined surface pressing contact between the latch 6 on the upper cover 2 and the upper end of the outer shell 1 disappears. Subsequently, through the deformation-restoring ability of the latch 6 on the upper cover 2, the upper cover 2... The buckle 6 is engaged and fixed with the bracket 7 at the upper end of the outer shell 1. Simultaneously, the guide strip 13 on the buckle 6 slides into contact with the guide groove on the corresponding bracket 7, thus securing the upper cover 2 to the outer shell 1 and limiting its horizontal relative rotation. Then, using the same principle, the worker fixes the lower cover 3 to the lower end of the outer shell 1. Next, the worker places the upper conductive shielding cover 8 over the outer side of the upper cover 2 from top to bottom, and the lower conductive shielding cover 9 over the outer side of the lower cover 3 from bottom to top. The upper conductive shielding cover 8 and the lower conductive shielding cover 9 are then installed and fixed together using the buckle 2 10 and bracket 2 11 in the same manner according to the aforementioned principle, thereby fixing the upper conductive shielding cover 8 and the lower conductive shielding cover 9 to the device. On the outside, the upper conductive shield 8 is a copper alloy upper conductive shield, and the lower conductive shield 9 is a copper alloy lower conductive shield. By wrapping the device with conductive shields, the high conductivity and magnetic permeability of copper alloy are used to block the influence of external electromagnetic interference on the internal circuit of the device through reflection and cancellation, while preventing the leakage of internal electromagnetic signals. When the electromagnetic force holding toggle switch is used for opening and closing, the electromagnet 475 is activated by the external control switch and kept in the normally open state. The operator pulls the cover 55 vertically upwards so that it moves vertically upwards along the outer upper end of the upper cover 2 and separates from the upper cover 2. The cover 55 drives the ring seat 54 to move synchronously, and the telescopic end of the telescopic column 52 and the spring 53 are stretched (the spring 53 is always in the tension). (Extended state), thus exposing the upper end of the toggle handle 473. Then, the operator moves the toggle handle 473 in the direction indicated by the arrow in the indicator arrow slot 12. The upper end of the toggle handle 473 rotates to the left around the axis of the second rotating shaft 472. The lower end of the toggle handle 473 drives the electromagnet 475 to rotate to the right via the angle plate 474. As the electromagnet 475 approaches the iron plate 471 on the right side around the axis of the second rotating shaft 472, it generates a magnetic field through the current magnetic effect. When current passes through its internal coil, the electromagnet magnetizes the iron core to enhance its magnetism. Since the distance between the iron plate 471 on the right and the electromagnet 475 is closer than the distance between the iron plate 471 on the left and the electromagnet 475 at this time...Therefore, the magnetic attraction force generated by electromagnet 475 on the right iron piece 471 is much greater than that on the left iron piece 471. This magnetic attraction force causes the moving contact 43 to rotate in the opposite direction around the axis of rotation 42, so that the right end of the moving contact 43 contacts the stationary contact 45, thus achieving the conduction operation of the electromagnetic force-holding toggle switch. This magnetic force also keeps the electromagnetic force-holding toggle switch in a stable conducting state. When the electromagnetic force-holding toggle switch is closed, moving the upper end of the toggle lever 473 to the right causes the left end of the moving contact 43 to rotate and contact the disconnect seat 46, thus achieving the disconnection operation of the electromagnetic force-holding toggle switch. This device uses the magnetic field generated by the coil inside the electromagnet 475 to achieve the switching operation of the electromagnetic force-holding toggle switch. After the toggle lever 473 is adjusted, the operator releases the upward pulling force applied to the cover 55. The cover 55 moves vertically downwards due to the tension and return force of the spring 53. The upper end of the upper cover 2 is sealed by the casing 55 to prevent external dust from entering. The rubber sealing ring 56, with its elastic properties, seals the gap between the casing 55 and the upper cover 2, further improving dust prevention. Simultaneously, the top wall of the casing 55 presses against the upper end of the toggle handle 473, using the pressure to limit the position of the toggle handle 473, further reinforcing the opening and closing position of the electromagnetically controlled toggle. After a period of use, the first ring seat 51 (fixed to the upper cover 2 by bolt 1) is removed from the top of the upper cover 2, and the second ring seat 54 (fixed to the casing 55 by bolt 2) is removed from the bottom of the casing 55. Then, the first ring seat 51, the second ring seat 54, the telescopic column 52, and the spring 53 are replaced to prevent aging of the spring 53 during use.

[0023] It is worth noting that the electromagnet 475 disclosed in the above embodiments can be WAXU-0630, and the external control switch is provided with a switch button corresponding to the electromagnet 475 for controlling its switching operation.
