Description

Technical Field

[0001] This invention relates to the field of magnetic latching relay technology, and in particular to a multi-connector relay driven by an eccentric magnet. Background Technology

[0002] Relays, as a fundamental automated component that utilizes electromagnetic principles to control the switching of circuits, are widely used in industrial control, power protection, communication equipment, and household appliances. As electrical systems evolve towards higher density, higher reliability, and greater intelligence, multi-connector relays need to integrate more independent contact pairs within a limited space to improve switching capabilities. Furthermore, they must ensure that each contact operates quickly, synchronously, and stably, and effectively suppress the electric arc generated during switching processes to extend lifespan and enhance anti-interference capabilities.

[0003] Traditional electromagnetic drive systems often employ a symmetrical magnetic circuit layout, with a relatively fixed magnetic field distance between the yoke and the permanent magnet or armature, resulting in a limited initial electromagnetic driving force. This leads to a relatively long relay engagement and disengagement time, making it difficult to meet the requirements of applications with stringent requirements for rapid switching. While the driving force can be increased by increasing the coil current or the size of the permanent magnet, this results in increased power consumption, larger size, and heat generation. Furthermore, in multi-connector relays, multiple moving contacts are typically mounted on the same linkage frame, driven by a single drive mechanism to achieve synchronous closing and opening. When all contacts simultaneously engage or disengage, it is equivalent to multiple load currents being switched on and off instantaneously, easily generating a strong electric arc. This arc not only burns the contact surface but also reduces contact reliability. Summary of the Invention

The first yoke is located between one end of the first armature plate and one end of the second armature plate. The other ends of the first armature plate and the second armature plate are located between the second yoke and the third yoke. The second permanent magnet is eccentrically positioned relative to the center of the sliding block. The distance from the second permanent magnet to the center of the sliding block is greater than the distance from the first permanent magnet to the center of the sliding block. The second permanent magnet is flush with one end of the first armature plate and one end of the second armature plate. The second permanent magnet is arranged in a straight line with one end of the first armature plate and one end of the second armature plate. The moving spring assembly includes a frame fixedly mounted on the sliding block, a plurality of moving contact frames fixedly mounted on the frame, and a plurality of moving contact assemblies mounted on the moving contact frames. When the sliding block moves, it drives the moving spring assembly to move synchronously, so that the moving contact assembly closes or separates from the stationary spring assembly.

[0006] Furthermore, the magnet assembly also includes a shielding plate disposed on the base, and sliding shafts are respectively disposed at the upper and lower ends of the sliding block. Sliding grooves are correspondingly disposed on the base and the shielding plate, and the sliding shafts are inserted into the sliding grooves.

[0007] Furthermore, the first armature plate and the second armature plate have a plate-like structure.

[0008] Furthermore, two mating blocks are provided on the end face of the frame facing the sliding block, and two mating grooves for connecting the sliding block to the moving spring assembly are provided on the end face of the sliding block facing the moving spring assembly. The mating blocks are T-shaped and matched with the mating grooves. The mating blocks are disposed in the mating grooves.

[0009] Furthermore, the moving contact assembly includes a slotted buckle plate connected to the moving contact frame, two U-shaped connecting plates disposed on the slotted buckle plate, two moving contact mounting plates disposed on the U-shaped connecting plates, a plurality of moving contacts disposed on the moving contact mounting plates, two first springs disposed on the moving contact mounting plates, and a second spring disposed on the first springs.

[0010] Furthermore, the moving contact frame includes multiple snap-fit ​​blocks disposed on the frame, the opening direction of the slotted buckle plate faces the frame, and snap-fit ​​holes are respectively provided on both ends of the slotted buckle plate, and the slotted buckle plate is snapped with the snap-fit ​​blocks through the snap-fit ​​holes.

[0011] Furthermore, the moving contact mounting plate has a plurality of positioning posts on one side facing the U-shaped connecting plate, the first spring has corresponding holes, the first spring is inserted into the moving contact mounting plate through the positioning posts, the U-shaped connecting plate fastens to both sides of the moving contact mounting plate, the first spring is located on the moving contact mounting plate and the U-shaped connecting plate, and the end of the U-shaped connecting plate is inserted into the through hole.

[0012] Furthermore, the first spring has a first bending portion at each end, and the second spring has a second bending portion at each end. The bending directions of the first bending portion and the second bending portion are opposite to each other. The first bending portion has a snap-fit ​​piece, and the second bending portion has a snap-fit ​​opening. The snap-fit ​​piece bends toward the snap-fit ​​opening and snaps into the snap-fit ​​opening.

[0013] Furthermore, the moving contact frame also includes a plurality of plug-in posts disposed on the frame, and the second spring is provided with plug-in holes that match the plug-in posts, and the plug-in posts are inserted into the plug-in holes.

[0014] Furthermore, the eccentric magnet driven multi-connector relay also includes multiple shielding components disposed on the base. The shielding components include multiple first partitions disposed on the base and multiple second partitions disposed on the moving spring assembly. The first partitions are disposed on the side wall of the base and located between the two stationary spring assemblies. The second partitions are disposed on the end face of the frame facing the first partitions. Two second partitions are disposed between the two moving contact assemblies and spaced apart from each other. One end of the first partition is located between the two second partitions.

[0015] Compared with existing technologies, the present invention provides an eccentric magnet-driven multi-connector relay by eccentrically positioning the second permanent magnet closer to the second and third yokes, thus shortening the magnetic field distance. When the coil is energized, the eccentric arrangement enhances the magnetic field interaction between the permanent magnet and the yoke, generating a larger initial electromagnetic driving force, thereby driving the sliding block to start quickly, effectively shortening the relay's engagement and disengagement time, and improving dynamic response efficiency. The limiting post causes the moving contacts on the two moving contact mounting plates to be staggered one in front of the other in a free state. During disconnection, the moving contact mounting plate with the limiting post moves back first, while the other moving contact mounting plate remains in contact with part of the stationary contact. Current can continue through the unseparated contacts, avoiding a sudden interruption of all current, ensuring that the first disconnected moving and stationary contacts are free of arcing, protecting one contact and preventing changes in the contact resistance of that circuit, thus controlling the variation in the overall relay's contact resistance.

[0026] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0027] like Figures 1 to 10 The diagram shows a structural schematic of an eccentric magnet-driven multi-connector relay provided by the present invention. The eccentric magnet-driven multi-connector relay includes a base 10, a coil assembly 20 disposed in the base 10, a magnet assembly 30 disposed on one side of the coil assembly 20, a moving spring assembly 40 disposed on the magnet assembly 30, multiple stationary spring assemblies 50 fixedly disposed on the side wall of the base 10, and multiple shielding assemblies 60 disposed on the base 10. It is conceivable that the eccentric magnet-driven multi-connector relay also includes other functional structures, such as arc-extinguishing plates, terminals, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0028] The base 10 is used to support the above-mentioned functional modules. Therefore, the base 10 is provided with a variety of functional structures, such as screws, bolts, clamps, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here.

[0029] The coil assembly 20 includes a coil 21, a first yoke 22 disposed at one end of the coil 21, and two second yokes 23 and a third yoke 24 disposed at the other end of the coil 21.

[0030] When the coil 21 is energized, N poles and S poles are generated at both ends of the coil 21, and the first yoke 22, the second yoke 23, and the third yoke 24 located at both ends are magnetized to generate magnetism, thereby interacting with the magnet assembly 30 to drive the magnet assembly 30 to slide. The magnetism of the first yoke 22 is opposite to that of the second yoke 23 and the third yoke 24 and is the same as that of one end of the coil 21 connected to it.

[0031] The magnet assembly 30 includes a sliding block 31 disposed on the base 10, a first permanent magnet 32 ​​disposed on the sliding block 31, a second permanent magnet 33 disposed on the sliding block 31, a first armature plate 34 disposed on the sliding block 31, a second armature plate 35 disposed on the sliding block 31, and a shielding plate 36 disposed on the base 10.

[0032] The sliding block 31, serving as a carrier of movable components, is slidably mounted on the base 10. Driven by the magnetic force generated by the energized coil, it slides linearly, causing all components on it to move together. Sliding shafts 37 are respectively provided at the upper and lower ends of the sliding block 31. Sliding grooves are correspondingly provided on the base 10 and the shielding plate 36. The sliding shafts 37 are inserted into the sliding grooves, thus restricting their direction of movement and causing linear reciprocating motion. Two mating grooves 38 are provided at the end of the sliding block 31 facing the moving spring assembly 40 for connecting to the moving spring assembly 40, thereby causing the moving spring assembly 40 to move synchronously when the sliding block 31 moves.

[0033] The first permanent magnet 32 ​​and the second permanent magnet 33 are located between the first armature plate 34 and the second armature plate 35. The permanent magnets themselves are magnetic, with one side being the N pole and the other side being the S pole. The first permanent magnet 32 ​​and the second permanent magnet 33 have the same magnetic direction. In this embodiment, the side of the first permanent magnet 32 ​​and the second permanent magnet 33 closest to the moving spring assembly 40 is the N pole, and the other side is the S pole.

[0034] The first armature plate 34 is located on the side of the first permanent magnet 32 ​​and the second permanent magnet 33 closer to the moving spring assembly 40, and the second armature plate 35 is located on the side of the first permanent magnet 32 ​​and the second permanent magnet 33 away from the moving spring assembly 40. Therefore, the magnetic pole of the first armature plate 34 is the N pole, and the magnetic pole of the second armature plate 35 is the S pole.

[0035] The first armature plate 34 and the second armature plate 35 have a plate-like structure. Both ends of the first armature plate 34 and the second armature plate 35 extend beyond both ends of the sliding block 31. The first yoke 22 is located between one end of the first armature plate 34 and one end of the second armature plate 35, and the other ends of the first armature plate 34 and the second armature plate 35 are located between the second yoke 23 and the third yoke 24. The second permanent magnet 33 is eccentrically positioned relative to the center of the sliding block 31, meaning the distance from the second permanent magnet 33 to the center of the sliding block 31 is greater than the distance from the first permanent magnet 32 ​​to the center of the sliding block 31. The second permanent magnet 33 is flush with one end of the first armature plate 34 and the second armature plate 35, and the second permanent magnet 33 is aligned in a straight line with one end of the first armature plate 34 and the second armature plate 35, thereby bringing the second permanent magnet 33 closer to the second yoke 23 and the third yoke 24. The eccentric setting of the second permanent magnet 33 makes it closer to the second yoke 23 and the third yoke 24. Since the magnetic field is smaller the farther away it is, the eccentric setting shortens the distance, thereby making the magnetic field interaction stronger when the coil is energized, thus generating a larger initial electromagnetic driving force, which helps the sliding block 31 to start quickly and shortens the relay action time.

[0036] Initially, the relay is in the open state between the moving and stationary contacts, such as... Figure 8 As shown. Next, the coil 21 is energized, generating a magnetic field. According to the right-hand rule, one end of the coil 21 is the N pole, and the other end is the S pole. The yokes tightly attached to both ends of the coil 21 are magnetized. The first yoke 22 has the same magnetism as one end of the coil 21, i.e., the N pole. The second yoke 23 and the third yoke 24 at the other end are magnetized to opposite magnetisms, i.e., the S poles. At this time, the first yoke 22 repels the first armature 34 and attracts the second armature 35. The second yoke 23 repels the second armature 35, and the third yoke 24 attracts the first armature 34. The resultant force of these attractive and repulsive forces pushes the sliding block 31 to move linearly. The sliding block 31 causes the moving spring assembly 40 and the stationary spring assembly 50 to close, as shown. Figure 9 As shown.

[0037] When disconnection is required, a reverse current is applied to the coil 21. This reverse current reverses the polarity of the magnetic field generated by the coil 21, causing the magnetism of the first yoke 22, the second yoke 23, and the third yoke 24 to also reverse. The reversed electromagnetic field interacts with the magnetic field of the permanent magnet. At this time, the first yoke 22 and the second armature plate 35 repel each other and attract the first armature plate 34; the second yoke 23 and the first armature plate 34 repel each other; and the third yoke 24 and the second armature plate 35 attract each other. The resultant force of these attractive and repulsive forces pushes the sliding block 31 to perform a reset linear motion. The sliding block 31 causes the moving spring assembly 40 to separate from the stationary spring assembly 50. Figure 10 As shown.

[0038] The shielding plate 36 is disposed on the base 10. The shielding plate 36 enables the sliding shaft 37 on the upper and lower sides of the sliding block 31 to be slidably connected to the shielding plate 36 and the base 10, respectively, so that the sliding block 31 can maintain balance when swinging. At the same time, the shielding plate 36 can also shield the magnetic field of the magnet assembly 30 from the influence of the magnetic field on the outside of the base 10.

[0039] The moving spring assembly 40 includes a frame 41 fixedly mounted on the sliding block 31, a plurality of moving contact frames 42 fixedly mounted on the frame 41, and a plurality of moving contact assemblies 43 mounted on the moving contact frames 42.

[0040] The frame 41 supports the various components of the moving spring assembly 40. Two mating blocks 411 are provided on the end face of the frame 41 facing the sliding block 31. The moving contact bracket 42 is located on the end face of the frame 41 facing the stationary spring assembly 50. The mating blocks 411 are T-shaped and match the mating groove 38. The mating blocks 411 are disposed within the mating groove 38, thereby enabling the frame 41 and the moving contact assembly 43 disposed on the frame 41 to move when the sliding block 31 moves.

[0041] Each pair of moving contact frames 42 can engage with one moving contact assembly 43. The number of moving contact assemblies 43 can be increased or decreased according to actual needs. In this embodiment, there are three moving contact assemblies 43, which are arranged at equal intervals along the length of the frame 41. The moving contact frame 42 includes multiple engaging blocks 421 disposed on the frame 41 and multiple insert posts 422 disposed on the frame 41. The engaging blocks 421 and the insert posts 422 are used to engage with the moving contact assemblies 43, which will be described in detail below in conjunction with the moving contact assemblies 43.

[0042] The moving contact assembly 43 includes a slotted buckle plate 431 connected to the moving contact frame 42, two U-shaped connecting plates 432 disposed on the slotted buckle plate 431, two moving contact mounting plates 433 disposed on the U-shaped connecting plates 432, a plurality of moving contacts 434 disposed on the moving contact mounting plates 433, two first springs 435 disposed on the moving contact mounting plates 433, and a second spring 436 disposed on the first springs 435.

[0043] The opening of the grooved buckle plate 431 faces the frame 41. The two ends of the grooved buckle plate 431 are respectively provided with buckle holes 4311, and the grooved buckle plate 431 is snapped into the snap block 421 through the buckle holes 4311. The slotted buckle plate 431 is provided with a plurality of through holes 4312, which are used to insert the end of the U-shaped connecting plate 432. The opening of the U-shaped connecting plate 432 faces the slotted buckle plate 431. The moving contact mounting plate 433 has moving contacts 434 inserted into both ends. The moving contact mounting plate 433 has a plurality of positioning posts 4331 on the side facing the U-shaped connecting plate 432. The first spring 435 is provided with corresponding holes. The first spring 435 is inserted into the moving contact mounting plate 433 through the positioning posts 4331. The U-shaped connecting plate 432 fastens the two sides of the moving contact mounting plate 433. The first spring 435 is located between the moving contact mounting plate 433 and the U-shaped connecting plate 432, thereby connecting with the moving contact mounting plate 433 while clamping the first spring 435. The end of the U-shaped connecting plate 432 is inserted into the through hole 4312. The first spring 435 has a first bending portion 437 at both ends, and the second spring 436 has a second bending portion 438 at both ends. The bending directions of the first bending portion 437 and the second bending portion 438 are opposite. When the moving and stationary contacts collide, the impact force causes the two opposing bending portions to undergo elastic deformation simultaneously, maximizing the absorption of collision energy and effectively suppressing contact bounce. The first bending portion 437 is provided with a snap-fit ​​piece 4371, and the second bending portion 438 is provided with a snap-fit ​​opening 4381. The snap-fit ​​piece 4371 bends towards the snap-fit ​​opening 4381 and snaps into it, thereby connecting the first spring 435 and the second spring 436. No screws, rivets, or welding are required; the connection and precise positioning between the springs can be quickly completed through simple snap-fit, greatly improving assembly efficiency and reducing process complexity and cost. The second spring plate 436 is provided with a plug hole 4361 that matches the plug post 422. When the slotted buckle plate 431 is snapped and fixed to the snap block 421 through the snap hole 4311, the plug post 422 will also be inserted into the plug hole 4361, thereby setting the entire moving contact assembly 43 on the moving contact frame 42.

[0044] The stationary spring assembly 50 includes two terminals 51 disposed on the base 10, and two stationary contacts 52 disposed on the terminals 51. The terminals 51 are connected to external electronic devices, and the moving contacts 434 at both ends of one of the moving contact mounting plates 433 respectively engage with the stationary contacts 52 on the two terminals 51.

[0045] Two limiting posts 4313 are provided on the end face of the slotted buckle plate 431 facing the moving contact mounting plate 433. Each of the two limiting posts 4313 corresponds to one moving contact mounting plate 433, thereby causing one of the moving contact mounting plates 433 to be lifted a certain distance by the two limiting posts 4313, thus controlling the position of the moving contacts 434 at both ends of one moving contact mounting plate 433. Figure 7 As shown, in the free state, the moving contacts 434 of the two moving contact mounting plates 433 are not on the same vertical line, but are arranged one in front of the other. The distance from the moving contact mounting plate 433 with the limiting post 4313 to the stationary spring assembly 50 is greater than the distance from the moving contact mounting plate 433 without the limiting post 4313 to the stationary spring assembly 50.

[0046] Therefore, when the moving contact and the stationary contact are closed, the two moving contact mounting plates 433 are simultaneously pushed towards the stationary spring assembly 50. However, the moving contact 434, which is closer to the stationary spring assembly 50, contacts the corresponding stationary spring assembly 50 first. As the pushing continues, the first spring 435 and the second spring 436 undergo slight elastic deformation due to their own elastic force, causing the rearward moving contact mounting plate 433 to continue moving until its moving contact also contacts the corresponding stationary contact. Conversely, when the moving contact and the stationary contact separate, the moving contact mounting plate 433 with the limiting post 4313 moves backward first, causing the moving contact 434 to separate from the stationary contact 52 first. As the frame 41 continues to move, the moving contact mounting plate 433 without the limiting post 4313 then moves backward until the moving contact 434 is completely separated from the stationary contact 52.

[0047] The relay disconnects in two stages to ensure that the first moving and stationary contacts disconnect without arcing. When the first moving contact mounting plate 433, equipped with the limiting post 4313, disconnects first, the other moving contact mounting plate 433 remains in contact with part of the stationary contact 52. Current can continue through the unseparated contacts, preventing a sudden interruption of all current. Therefore, no arcing occurs between the first disconnected moving and stationary contacts, protecting one contact and ensuring that the contact resistance of that contact remains unchanged. The overall contact resistance of the relay is related to the moving contacts 434 on the two moving contact mounting plates 433. If the contact resistance of both moving and stationary contacts increases significantly due to arcing, the overall contact resistance of the relay will also increase, affecting normal operation. However, by ensuring that the resistance of one moving and stationary contact remains unchanged, even if the resistance of the other moving and stationary contact increases due to arcing, the increase in the overall contact resistance of the relay will be limited by the one with unchanged contact resistance, keeping the overall contact resistance of the relay within a controllable range.

[0048] The shielding assembly 60 includes a plurality of first partitions 61 disposed on the base 10 and a plurality of second partitions 62 disposed on the moving spring assembly 40. The first partitions 61 are disposed on the side wall of the base 10 and located between the two stationary spring assemblies 50. The second partition 62 is disposed on the end face of the frame 41 facing the first partition 61. Two second partitions 62 are disposed between the two moving contact assemblies 43, so that there is a certain distance between the two second partitions 62. One end of the first partition 61 is located between the two second partitions 62, thereby separating the multiple stationary spring assemblies 50 and the multiple moving spring assemblies 40, so that one stationary spring assembly 50 and one moving spring assembly 40 are in the same space, thereby reducing the mutual influence of electric arcs during switching.

[0049] Compared with the prior art, the eccentric magnet driven multi-connector relay provided by the present invention shortens the magnetic field action distance by eccentrically setting the second permanent magnet 33 closer to the second yoke 23 and the third yoke 24. When the coil 21 is energized, the eccentric arrangement enhances the magnetic field interaction between the permanent magnet and the yoke, generating a larger initial electromagnetic driving force, thereby driving the sliding block 31 to start quickly, effectively shortening the relay's engagement and disengagement action time, and improving dynamic response efficiency. The limiting post 4313 causes the moving contacts 434 on the two moving contact mounting plates 433 to be staggered one in front of the other in a free state. When disconnected, the moving contact mounting plate 433 with the limiting post 4313 moves back first, while the other moving contact mounting plate 433 still maintains contact with part of the stationary contact 52. The current can continue through the unseparated contact, avoiding the instantaneous interruption of all current, ensuring that the first disconnected moving and stationary contacts have no arc, protecting one contact and ensuring that the contact resistance of that circuit does not change, thus controlling the change in the contact resistance of the entire relay.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
