Description
Technical Field
[0001] This application relates to the field of relay technology, and in particular to a novel magnetic latching relay. Background Technology
[0002] A magnetic latching relay is a type of relay that uses a permanent magnet or magnetic circuit self-locking to maintain the state of the contacts. Its most significant feature is that it can switch states with just a pulse drive, without the need for continuous power supply.
[0003] For existing magnetic latching relays, a single-contact method is typically used. The moving contact is fixedly mounted on a flexible armature, with one end of the armature fixedly mounted on a stationary foot. The stationary contact is fixedly mounted on an insulating base. When the device is energized, the permanent magnet causes the armature to move, thereby closing the moving contact and the stationary contact on the armature. Depending on the type of magnetic latching relay, the distance between the moving contact and the stationary contact varies according to national standards.
[0004] However, the larger the distance between the moving contact and the stationary contact, the longer the response time of the moving contact and the stationary contact, which increases the driving energy consumption. In addition, the larger the safety distance between the moving contact and the stationary contact, the larger the overall size of the relay, which is not conducive to high-density PCB layout or miniaturized equipment, thus making the working efficiency of the device not high. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a novel magnetic latching relay that solves the problem that the increased distance between the moving and stationary contacts in single-contact methods results in low device efficiency.

There are two rotating rods, which are respectively fixedly connected to opposite sides of the fixed shell. The ends of the two rotating rods away from the fixed shell are respectively rotatably connected to opposite sides inside the outer shell.
[0009] Furthermore, the actuating component includes a protective shell, a rotating rod, a push plate, and a magnet. The protective shell is fixedly installed on the arc surface of the rotating rod. The two ends of the rotating rod are rotatably connected to opposite sides inside the outer shell. There are two push plates, which are hinged to the upper and lower sides of the protective shell respectively. The two ends of the rotating plate are rotatably connected to one side of the two push plates respectively. There are two magnets, which are fixedly installed on opposite sides of the protective shell respectively.
[0010] Furthermore, the electromagnetic component includes a connector, an iron core, a coil, and yokes. The connector is fixedly installed on one side of the housing, the iron core is fixedly installed inside the housing, the coil is wound around the iron core, and two yokes are fixedly installed at both ends of the iron core, with the two yokes respectively attached to one side of the two magnets.
[0011] Furthermore, the rotating plate includes beryllium copper and copper. There are two copper plates. The beryllium copper and copper plates are fixedly installed on the fixed shell. The beryllium copper is fixedly installed between the two copper plates. The length of the beryllium copper is greater than that of the copper plates. The two ends of the beryllium copper are rotatably connected to one side of the two push plates. The two moving contacts are fixedly installed on one side of the copper plates. The two rotating components are rotatably connected to the opposite sides of the beryllium copper.
[0012] Furthermore, the tops of the two moving contacts are convex surfaces, and the top surfaces of the first stationary contact and the second stationary contact are convex surfaces.
[0013] Furthermore, a connecting assembly is provided on the back of the outer casing. The connecting assembly includes a fixing block and a connecting post.

[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] 1. When using the device, the first and second stationary feet are connected to an external circuit. The electromagnetic component drives the pushing component to slide on the bottom surface inside the housing, pushing the component through the second stationary foot and contacting the rotating mechanism. This causes the rotating mechanism to rotate inside the housing, thereby causing the two moving contacts to rotate synchronously and respectively engage with the first and second stationary contacts. Compared to the prior art, where the moving contacts are fixedly mounted on the armature, and the distance between the moving and stationary contacts is a fixed value, this technology, because the rotating mechanism has no initial elasticity, allows for adjustments to the distance between the first and moving contacts or the distance between the second and stationary contacts without increasing the coil drive power or the relay size. The distance between the moving contact and the other moving contact is greater than the contact gap in the prior art. The distance between the first stationary contact and the second stationary contact is twice the distance between the moving contact and the stationary contact in the prior art. By rotating the rotating mechanism, the two moving contacts on the rotating mechanism are respectively engaged with the first stationary contact and the second stationary contact, which shortens the single contact stroke, solves the problem of the response time between the moving contact and the stationary contact in the relay, solves the problem of the safe distance between the moving contact and the stationary contact, and solves the problem of increased drive energy consumption. It also solves the problem of difficulty in quickly extinguishing the arc, and solves the problem of increased overall size of the relay, which is not conducive to high-density PCB layout or miniaturized equipment, thus improving the working efficiency of the device.
[0017] 2. When using the device, the electromagnetic component drives the push component, which in turn pushes the rotating plate. This causes the push component to rotate between opposite sides inside the housing, allowing the rotating plate to rotate on the push component. Because the push component is fixed to the rotating plate, and two moving contacts are installed at opposite ends of the rotating plate, when the rotating plate rotates, the two moving contacts move synchronously, contacting or separating from the first and second stationary contacts respectively, thus opening and closing the circuit. This simultaneous action of the two moving contacts shortens the contact switching time and improves the relay's response speed. Furthermore, the distance between the first stationary contact and one moving contact is equal to the distance between the second stationary contact and the other moving contact, ensuring synchronous closure of both pairs of contacts and avoiding arcing caused by premature contact on one side. Due to the shortened travel of the moving contacts, the driving force required by the electromagnetic component is reduced, thereby reducing power consumption, optimizing internal space utilization, and making the overall relay size smaller. This makes it suitable for high-density PCB layouts and miniaturized equipment.
[0018] 3. When using the device, the two rotating rods are symmetrically distributed on opposite sides of the fixed shell. The electromagnetic component drives the push component, which in turn pushes the rotating plate. As a result, the two rotating rods rotate on opposite sides inside the shell, causing the fixed shell and the rotating plate to rotate together on the two rotating rods. This improves the convenience of the device. Because the two rotating rods are symmetrically arranged, the rotating plate is subjected to balanced force, reducing uneven wear and increasing mechanical life. Attached Figure Description

Detailed Implementation
[0027] The present application will be further described in detail below with reference to the accompanying drawings.
[0028] Example, refer to Figures 1-6A novel magnetic latching relay includes a housing 1, within which a contact mechanism 2 is fixedly installed. The contact mechanism 2 includes a first stationary foot 21 and a second stationary foot 22, which are respectively fixedly installed on one side inside the housing 1. A first stationary contact 23 is fixedly installed on the first stationary foot 21, and a second stationary contact 24 is fixedly installed on the second stationary foot 22. A rotating mechanism 3 is rotatably connected to one side inside the housing 1 and is located between the first stationary foot 21 and the second stationary foot 22. Two moving contacts 31 are fixedly installed on the rotating mechanism 3, which cooperate with the first stationary contact 23 and the second stationary contact 24 to realize the circuit switching. A pushing component 4 for driving the rotating mechanism 3 to rotate is fixedly installed inside the housing 1, and an electromagnetic component 5 for driving the pushing component 4 to rotate is fixedly installed inside the housing 1. When using the device, the first stationary foot 21 and the second stationary foot 22 are connected to an external circuit. The electromagnetic component 5 drives the pushing component 4 to slide on the bottom surface inside the housing 1. The pushing component 4 passes through the second stationary foot 22 and abuts against the rotating mechanism 3, causing the rotating mechanism 3 to rotate inside the housing 1. This causes the two moving contacts 31 to rotate synchronously and respectively engage with the first stationary contact 23 and the second stationary contact 24. (Refer to...) Figure 5 Compared to the prior art, where the moving contact 31 is fixedly mounted on the armature 8, and the distance between the moving contact 31 and the stationary contact 81 is a fixed value, in this technology, because the rotating mechanism 3 has no initial elastic force, the distance between the first stationary contact 23 and the moving contact 31, or the distance between the second stationary contact 24 and another moving contact 31, can be greater than the contact gap in the prior art without increasing the driving power or the size of the relay. The distance between the first stationary contact 23 and the second stationary contact 24 is double the distance between the moving contact 31 and the stationary contact 81 in the prior art. By rotating the rotating mechanism 3, the two moving contacts 31 on the rotating mechanism 3 are respectively engaged with the first stationary contact 23 and the second stationary contact 24, which shortens the single contact stroke, solves the response time problem between the moving contact 31 and the stationary contact 81 in the relay, solves the problem of the safe distance between the moving contact 31 and the stationary contact 81, and solves the problem of increased drive energy consumption. It also solves the problem of difficulty in quickly extinguishing the arc, and solves the problem of increased overall relay size, which is not conducive to high-density PCB layout or miniaturized equipment, thus improving the working efficiency of the device.
[0029] Reference Figure 1The rotating mechanism 3 includes a rotating plate 32 and a rotating assembly 33. The two ends of the rotating plate 32 are rotatably connected to the pushing assembly 4. The rotating plate 32 is fixedly installed on the rotating assembly 33. The rotating assembly 33 is rotatably connected between opposite sides inside the housing 1. Two moving contacts 31 are fixedly installed on opposite sides of the rotating plate 32. The two moving contacts 31 are respectively in contact with the first stationary contact 23 and the second stationary contact 24. The distance between the first stationary contact 23 and one moving contact 31 is equal to the distance between the second stationary contact 24 and the other moving contact 31. When using the device, the electromagnetic component 5 drives the push component 4, which in turn pushes the rotating plate 32. This causes the rotating component 33 to rotate between opposite sides inside the housing 1, allowing the rotating plate 32 to rotate on the rotating component 33. Since the rotating component 33 is fixed on the rotating plate 32, and the two moving contacts 31 are respectively installed at both ends of the rotating plate 32, when the rotating plate 32 rotates, the two moving contacts 31 move synchronously, contacting or separating from the first stationary contact 23 and the second stationary contact 24, respectively, thereby realizing the opening and closing of the circuit. This allows the two moving contacts 31 to act simultaneously, shortening the contact switching time and improving the relay response speed. Furthermore, the distance between the first stationary contact 23 and one moving contact 31 is equal to the distance between the second stationary contact 24 and the other moving contact 31, ensuring that the two pairs of contacts close synchronously and avoiding arcing problems caused by premature contact on one side. Due to the shortened stroke of the moving contact 31, the driving force required by the electromagnetic component 5 is reduced, thereby reducing power consumption, optimizing the utilization of internal space, and making the overall size of the relay smaller, suitable for high-density PCB layouts and miniaturized devices.
[0030] Reference Figure 1 , Figure 3 as well as Figure 4 The rotating assembly 33 includes a fixed housing 331 and rotating rods 332. A rotating plate 32 is fixedly mounted on the fixed housing 331. Two rotating rods 332 are provided and fixedly connected to opposite sides of the fixed housing 331. The ends of the two rotating rods 332 away from the fixed housing 331 are rotatably connected to opposite sides inside the outer housing 1. In use, the two rotating rods 332 are symmetrically distributed on opposite sides of the fixed housing 331. The electromagnetic assembly 5 drives the push assembly 4, which in turn pushes the rotating plate 32. This causes the two rotating rods 332 to rotate on opposite sides inside the outer housing 1, making the fixed housing 331 and the rotating plate 32 rotate together on the two rotating rods 332, improving the convenience of the device. Because the two rotating rods 332 are symmetrically arranged, the rotating plate 32 experiences balanced force, reducing uneven wear and increasing mechanical life. (Refer to...) Figure 4 Alternatively, a rotating hole can be opened on one side of the rotating plate 32 and passed through it. Then, a rotating rod 332 is passed through the rotating hole and rotatably connected. The two ends of the rotating rod 332 are fixed to the opposite sides of the outer shell 1, which can also realize the rotation of the rotating plate 32 inside the outer shell 1. This shows that the rotating component 33 in the device can adopt a variety of rotation methods, which improves the convenience of the device.
[0031] Reference Figure 1 The pushing component 4 includes a protective shell 41, a rotating rod 42, a push plate 43, and a magnet 44. The protective shell 41 is fixedly installed on the arc surface of the rotating rod 42. The two ends of the rotating rod 42 are rotatably connected to opposite sides inside the outer shell 1. There are two push plates 43, which are respectively hinged to the upper and lower sides of the protective shell 41. The two ends of the rotating piece 32 are rotatably connected to one side of the two push plates 43. There are two magnets 44, which are fixedly installed on opposite sides of the protective shell 41. When the electromagnetic component 5 exerts a reaction force on the pushing component 4, the protective shell 41 and the rotating rod 42 are fixedly connected on the arc surface. The two ends of the rotating rod 42 are pivotally connected to the side wall of the outer shell 1, forming a stable rotation fulcrum. The push plate 43 is connected to the protective shell 41 by a hinge. The two push plates 43, the rotating plate 32 and the protective shell form a four-bar linkage mechanism, ensuring that the push plate 43 rotates the rotating plate 32 during the movement. The magnets 44 are symmetrically arranged on both sides of the protective shell 41, and generate precise magnetic force balance under the action of the electromagnetic component 5. When the electromagnetic component 5 is energized, the pushing component 4 is driven by the reaction force, and the push plate 43 pulls the rotating plate 32 to reset it, which improves the convenience of the device.
[0032] Reference Figure 1 The electromagnetic component 5 includes a connector 51, an iron core 52, a coil 53, and yokes 54. The connector 51 is fixedly installed on one side of the housing 1, the iron core 52 is fixedly installed inside the housing 1, the coil 53 is wound around the iron core 52, and two yokes 54 are fixedly installed at both ends of the iron core 52, with each yoke 54 attached to one side of a magnet 44. The connector 51 serves as an external power interface and is fixed to the side wall of the housing 1. The iron core 52 serves as the core of the magnetic circuit and is vertically installed inside the housing 1. High-purity copper wire is precision wound to form the excitation coil 53. Two high-permeability yokes 54 are symmetrically installed at both ends of the iron core 52, forming an air-gap adjustable magnetic circuit coupling structure with the magnets 44 on the housing 1. When the coil 53 is energized, the generated electromagnetic field forms a complete magnetic circuit through the iron core 52, yokes 54, and magnets 44, driving the component 4 to move precisely. When the power is off, the residual magnetic field of the yokes 54 and magnets 44 is quickly demagnetized, ensuring instantaneous contact separation and improving the convenience of the device.
[0033] Reference Figure 1The rotating plate 32 includes beryllium copper 321 and copper 322. There are two copper 322. The beryllium copper 321 and copper 322 are fixedly installed on the fixed shell 331. The beryllium copper 321 is fixedly installed between the two copper 322. The length of the beryllium copper 321 is greater than that of the copper 322. The two ends of the beryllium copper 321 are rotatably connected to one side of the two push plates 43 respectively. The two moving contacts 31 are fixedly installed on one side of the copper 322 respectively. The two rotating components 33 are rotatably connected to the opposite sides of the beryllium copper 321 respectively. Multiple beryllium copper 321s are stacked, and the beryllium copper 321s and copper 322s are fixedly installed on the fixed housing 331 by injection molding. The two moving contacts 31 are riveted to the beryllium copper 321s and copper 322s. When using the device, the two ends of the beryllium copper 321s are rotatably connected to one side of the two push plates 43. The excellent elasticity of the beryllium copper 321s makes the push plates 43 less prone to deformation and damage when pulling or pushing the beryllium copper 321s, thus improving the service life of the device. Furthermore, the good conductivity of the copper 322s ensures good energization when the two moving contacts 31 are in contact with the first stationary contact 23 and the second stationary contact 24, respectively, thus improving the working efficiency of the device.
[0034] Reference Figure 2 The top of the moving contact 31 is convex, and the top surfaces of the first stationary contact 23 and the second stationary contact 24 are also convex. When the device is in use, the convex surfaces of the two moving contacts 31 contact the convex surfaces of the first stationary contact 23 and the second stationary contact 24 respectively. During the closing process, the moving contacts 31 and the first stationary contact 23 and the second stationary contact 24 will self-align due to the curved surface contact. Even with slight assembly deviations or mechanical vibrations, they can automatically adjust to the optimal contact position, avoiding poor contact caused by misalignment and improving the device's working efficiency.
[0035] Reference Figure 6 as well as Figure 7A connecting component 9 is provided on the back of the outer casing 1. The connecting component 9 includes a fixing block 91 and a connecting post 92. The fixing block 91 is fixedly installed on the back of the outer casing 1. A plug hole 911 is provided on the side of the fixing block 91 away from the outer casing 1. The connecting post 92 is inserted into the plug hole 911. A placement groove 921 is provided on the arc surface of the connecting post 92. A spring 922 is fixedly connected to the bottom surface of the placement groove 921. A plug post 923 is fixedly connected to the end of the spring 922 away from the placement groove 921. The top surface of the plug post 923 is arc-shaped. A through hole 912 is provided on one side of the fixing block 91. The plug post 923 is snapped into the through hole 912. A connecting ring 924 is fixedly connected to the end of the connecting post 92 away from the fixing block 91. When the device is installed in one place for use, the connecting post 92 is inserted into the insertion hole 911. The top surface of the connecting post 923 abuts against the inner wall of the insertion hole 911, compressing the spring 922. When the connecting post 923 slides to the through hole 912, the spring 922 rebounds, causing the connecting post 923 to snap into the through hole 912. Then, it is fixedly connected to the connecting ring 924 through an external connector, thus completing the fixed installation of the device. When installation can be performed without using the connecting component 9, pressing the connecting post 923 compresses the spring 922, causing the connecting post 923 to disengage from the through hole 912. Then, pulling out the connecting post 92 separates the connecting post 92 from the fixing block 91, improving the ease of installation of the device.
[0036] Reference Figure 6 as well as Figure 7 A button 93 is fixedly installed on one side of the fixing block 91, and the button 93 is located at the through hole 912. When it is necessary to disassemble the connecting component 9, the button 93 is pressed to make the button 93 abut against the top surface of the plug post 923. The plug post 923 compresses the spring 922, which can disengage the plug post 923 from the through hole 912, thus improving the convenience of the device.
[0037] Working principle:
[0038] 1. When using the relay, connector 51 is plugged into an external power source, and the first stationary pin 21 and the second stationary pin 22 are connected to the external circuit. The generated electromagnetic field forms a complete magnetic circuit through the iron core 52, yoke 54 and magnet 44, driving the protective shell 41 to rotate on the rotating rod 42. This causes the two push plates 43 to push the rotating plate 32, causing the two rotating rods 332 to rotate on opposite sides inside the shell 1. As a result, the rotating plate 32 rotates, and the rotation of the rotating plate 32 causes the two moving contacts 31 to engage with the first stationary contact 23 and the second stationary contact 24 respectively, improving the working efficiency of the device.
[0039] 2. When the relay is de-energized, the push plate 43 pulls the rotating plate 32, causing the two rotating rods 332 to rotate on opposite sides inside the housing 1. Thus, the rotating plate 32 completes the reverse rotation under the pull of the two push plates 43, forcibly separating the two moving contacts 31 from the first stationary contact 23 and the second stationary contact 24 respectively, improving the convenience of the device.
