The fixed part includes a base integrally formed by injection molding, a coil assembly, a stationary spring, and a welding part. The coil assembly includes an iron core and a coil, which can be directly wound around the outer circumference of the iron core, or indirectly wound around the outer circumference of the iron core through a coil frame (usually made of plastic) injection-molded on the outer side of the iron core. The iron core has two magnetic pole surfaces exposed above the upper end of the base. The stationary contact of the stationary spring is exposed above the upper end of the base, and the welding part forms a welding station exposed above the upper end of the base. The oscillating part is located at the upper end of the base and has a fixed connection part that is fixed to the welding station. The oscillating part is integrally formed by injection molding of an armature and a moving spring. The two ends of the armature have two attraction parts corresponding to the magnetic pole surfaces, and the moving spring has a moving contact corresponding to the stationary contact. The oscillating part forms a rotation fulcrum with the support part of the base. The coil assembly drives the armature to oscillate back and forth, causing the moving and stationary contacts to close or open. In practice, it has been found that the moving and stationary contacts of existing relays have the risk of unstable contact. Utility Model Content

[0017] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means: Through continuous observation, experimentation, and research, the applicant has determined that the technical problem of "risk of unstable contact between the moving and stationary contacts of existing relays" arises because, in existing technologies, the fixed part is typically directly welded to the upper surface of the soldering station. When the swinging part oscillates at high frequency, it continuously exerts alternating tearing forces on the fixed part and the solder joint between the fixed part and the soldering station. This repeated stress cycle easily leads to fatigue cracks at the solder joint, which gradually propagate and eventually cause connection failure. If the solder joint does not completely detach, the static contact pressure when the contacts are closed will decrease or even disappear. When the static contact pressure between the moving and stationary contacts decreases, the contact between them becomes unreliable. When subjected to external interference, the closed moving and stationary contacts exhibit slight vibrations, leading to an increase in the contact resistance between them. When the static contact pressure disappears, the relay's moving and stationary closed contacts, which were subjected to the static contact pressure, will disconnect. When applied to high-frequency signal relays, a decrease in static closing pressure leads to a smaller contact area between the moving and stationary contacts. According to the parallel-plate capacitor theory, this causes a deviation in the characteristic impedance between the contacts, increasing transmission line losses. When the static closing pressure is even lower, external forces can cause unreliable contact between the moving and stationary contacts, resulting in slight jitter or disconnection of the closed contacts. This alters the capacitance between the contacts, causing a deviation in their characteristic impedance and further increasing transmission line losses.

[0018] In the first technical solution and its preferred embodiment, the swinging part swings relative to the fixed part on a first plane. The first plane is the plane where the motion trajectory of the swinging part is located, and is an abstract reference plane. This plane is perpendicular to the swinging axis of the swinging part. The swinging here means that the swinging part has no motion component in the direction of the swinging axis, or only a small motion component caused by manufacturing / assembly error. The main body of the swinging part serves as the core structure, while the connecting part acts as a transition structure between the main body and the fixed part, enabling force transmission and connection. The connecting part includes an extension section and a bent section. The extension section extends along the extension direction of the main body, and the bent section is located at the end of the extension section. The bent section and the extension section form an angle on a first plane. The fixed connection part is located on the bent section; that is, the bent section is not located on the side where the width direction of the extension section is located, but rather at the end where the length direction of the extension section is located. Compared to structures without bends, the addition of extension and bending sections increases the elasticity of the connection. The bending section absorbs vibration energy, creating a dual structure of "rigid support - elastic buffer" at the connection. After the bending section is fixed, the extension section, designed along the main body's extension direction, maintains a consistent force transmission path during the swinging motion. When the extension section is subjected to force, the force is absorbed by the bending section and not transmitted to the fixed part. In other words, the elasticity of the bending section buffers alternating stress during the swinging process, significantly reducing the risk of failure at the connection point between the bending section and the movable part. This ensures the reaction force when the contact opens and reliable closure when the contact closes. Furthermore, the angled structure between the bending and extension sections generates preload to meet different contact pressure requirements, further ensuring rapid contact opening or stable closure.

[0019] In the second technical solution and its preferred embodiment, the bending section is provided with an arc transition section that connects to the end of the extension section. The arc transition avoids the stress concentration problem of right-angle bending and can further disperse stress. In addition, the arc radius is adjustable to adapt to different contact pressure requirements.

[0020] In technical solution three and its preferred embodiments, the fixed part is provided with a connecting wall for fixing and fitting with the bent section. Since the connecting wall fits with the bent section, the connecting wall also forms an angle with the extension section in the first plane. The connecting wall forms an angle with the second plane. The second plane is perpendicular to the first plane and passes through the swing axis of the swinging part. The second plane is an abstract reference plane, but it always satisfies the geometric relationship of being perpendicular to the first plane and parallel to the swing axis. The connecting wall can optimize the force direction when the bent section and the connecting wall are fixed, reduce the shear force component parallel to the fixed surface, and increase the normal pressure, thereby improving the fixed strength. Thus, through the elastic buffer of the extension section and the bent section, combined with the inclined design of the connecting wall, the tearing force generated by the swing is dispersed along the inclined direction to the whole of the fixed part, rather than concentrated on the fixed surface, thereby avoiding stress fatigue problems. In addition, compared with the connecting wall parallel to the second plane, it also makes the connecting part and the connecting wall form a self-locking structure, making the fixed surface more conducive to bearing the swing stress, further improving the connection stability between the bent section and the connecting wall.

[0021] In technical solution four and its preferred embodiments, when the stationary contact is a normally open stationary contact, the connecting wall is inclined from bottom to top toward the side away from the normally open stationary contact. The extension section is located between the normally open stationary contact and the connecting wall along the Y-axis. The inclined setting of the connecting wall can increase the disconnection distance between the normally open stationary contact and the corresponding moving contact, avoiding false triggering. When used in a high-frequency signal relay, it also increases the high-frequency signal isolation between the normally open stationary contact and the corresponding moving contact. When the stationary contact is a normally closed stationary contact, the connecting wall is inclined from bottom to top toward the side closer to the normally closed stationary contact. When the connecting wall is located between the extension section and the connecting wall along the Y-axis, it can increase the distance between the normally closed stationary contact and the corresponding moving contact. The closing pressure effectively resists accidental contact disconnection caused by external vibration or interference. When the relay closes, the normally closed stationary contact will bounce back upon initial contact. A greater closing pressure can significantly shorten the bounce time and improve the response speed. When used in high-frequency signal relays, it can reduce bounce, thereby ensuring the contact stability of the normally closed stationary contact and the continuity of high-frequency signal transmission. (When the moving contact bounces back, a capacitance effect will occur between the moving and stationary contacts when they open. The characteristic impedance of the signal transmission line will deviate from the expected standard value (such as 50Ω or 75Ω), thus causing high-frequency signal loss when passing between the moving and stationary contacts.) In practical applications, the contact gap, contact overtravel force, and contact closing pressure can be adjusted by adjusting the tilt angle of the connecting wall, thereby improving the contact stability of the normally closed contacts. When applied to high-frequency signal relays, it can reduce the capacitance effect of the normally closed contacts and reduce signal loss.

[0022] In technical solution five and its preferred embodiments, the integrated injection molding of the fixed part improves the positional accuracy and relative stability of each functional component (such as coil, stationary contact, and common terminal). The stationary spring part is provided with at least one stationary spring assembly, and each stationary spring assembly is provided with a normally open stationary contact, a common terminal, and a normally closed stationary contact arranged sequentially along the Y-axis. The swinging part is provided with a normally open moving contact corresponding to the normally open stationary contact and a normally closed moving contact corresponding to the normally closed stationary contact, forming a seesaw layout, which helps to reduce swing eccentricity or additional torque, thereby achieving force balance. The connecting part is located on the moving spring, which is convenient for processing.

[0023] In technical solution six and its preferred embodiments, the extension section is at least partially suspended from the base. The suspended section easily absorbs the energy of the swing deformation, further reducing the swing stress transmitted to the fixed surface between the bent section and the connecting wall, and reducing the frictional loss of the extension section during swing, thus improving its lifespan and providing movement space for the swing of the connecting part. When used in high-frequency signal relays, less frictional loss also makes the connecting part less prone to deformation and does not increase surface roughness, thereby ensuring the stability of signal transmission.

[0024] In technical solution seven and its preferred embodiments, the support portion further reduces local stress concentration and improves the stability of the relay's operation and release process. Furthermore, by adjusting the bending radius R of the connecting portion (i.e., changing the length L of the cantilever beam from the center of the bending radius to the other end of the extension section), the rotational torque M1 (M1=F1×L) must remain constant while maintaining the same rotation range (fixed relay stroke). When R is decreased, L increases, and the suction force F required for the armature and core to close is smaller, thereby reducing the ampere-turns of the relay coil (reducing power consumption). Conversely, increasing R shortens L, increasing the required suction force F, and requiring an increase in ampere-turns to ensure suction force (but increasing power consumption). When applied to high-frequency signal relays, while ensuring the shortest transmission line distance and power consumption meets application requirements, the length of L can be changed by flexibly adjusting the value of R to achieve precise matching of suction force and reaction force during relay operation.

[0025] In technical solution eight and its preferred embodiments, the avoidance part provides motion space for the swing of the extension section, avoids additional stress caused by structural interference, and improves the operational reliability of the swing part; in addition, the setting of the avoidance slope allows the cantilever beam to rotate a larger range of angles, and makes the normally closed end moving and stationary contacts farther apart, thereby increasing the isolation between the normally closed end moving and stationary contacts.

[0026] In technical solution nine and its preferred embodiment, symmetrical notches for welding to the connecting wall are provided on both sides of the bending section in the width direction. These two notches increase the welding strength and minimize the welding contact area A between the bending section and the connecting wall. According to the parallel plate capacitor theory (Cp=εA / d), reducing the contact area A significantly reduces the shunting effect of high-frequency signals and reduces the distributed capacitance of the welded part. This allows the characteristic impedance of the welded transmission line between the connecting part and the connecting wall to be precisely matched to 50Ω or 75Ω (the standard impedance value for high-frequency signals), effectively reducing the transmission loss of high-frequency signals in this welding process. The connecting part is located on a moving spring, which facilitates processing.

[0027] In the tenth technical solution and its preferred embodiment, the mating wall extends along the Y-axis and is at least partially wrapped by the base; there is an arc transition between the mating wall and the connecting wall. The arc transition avoids the stress concentration problem of right-angle bending and can further disperse stress. In addition, the arc radius is adjustable, and the connecting wall can be adjusted by adjusting the arc radius to adapt to different contact pressure requirements.

[0028] In technical solution eleven and its preferred embodiment, the slag guide slope can use the height difference to guide the welding slag generated during welding to roll naturally to the outside of the relay, avoiding the accumulation of welding slag from affecting the internal operating mechanism of the relay and ensuring the reliability of the relay's long-term operation.

[0029] In technical solution 12 and its preferred embodiment, the connecting arm extends along the width direction of the moving spring, so that the connecting part adopts a right-angle bending structure, which reduces the number of bends in the connecting part, reduces the capacitance effect, and makes the characteristic impedance matching of this part closer to the expected standard value (such as 50Ω or 75Ω). This avoids problems such as increased capacitance effect caused by excessive bending, and shortens the transmission path of high-frequency signals in the relay, thereby reducing the loss of high-frequency signals during transmission.

[0030] In the thirteenth technical solution and its preferred embodiment, since in the prior art, the rotational engagement between the swinging part and the fixed part is completed by the moving spring and the base of the fixed part, and the rotational engagement structure between the rotating shaft and the rotating groove, the rotating shaft is farther away from the first surface than the extension section. This design can effectively avoid the deformation of the moving spring surface due to friction or force, thereby stably maintaining the surface roughness of the moving spring in this area, ensuring that the characteristic impedance of the signal transmission line does not drift due to contact deformation, and ultimately significantly reducing the transmission loss of high-frequency signals and improving the signal transmission reliability of the relay under complex working conditions. Specifically, firstly, the contact fit between the rotating shaft and the rotating groove completely avoids direct contact between the base and the moving spring, preventing deformation or surface roughness changes in the moving spring due to force and ensuring that the characteristic impedance of the transmission line is not interfered with, thereby effectively reducing signal transmission loss during relay operation. Secondly, the convex-concave structure also has a limiting function, which can precisely control the rotation range of the moving swing part and significantly improve its assembly accuracy with the fixed part. At the same time, the tight fitting design effectively reduces the mating distance between the two, creating conditions for reducing the overall height of the relay, thereby reducing the relay's stroke and making the relay's action / release faster. Thirdly, this structure allows for a smaller bending angle θ at the end of the connection part (bending section and extension section), which reduces the risk of plastic deformation at the bending part and reduces signal transmission loss caused by deformation. More importantly, this improvement makes the contact pressure distribution of the normally closed moving and stationary contacts more uniform, and the closed state more stable and reliable.

[0039] In the claims and the description other than the embodiments, the terms "X-axis direction," "Y-axis direction," and "Z-axis direction" only refer to a feature having one of the aforementioned directions being perpendicular to a feature having another direction, and do not require that they be implemented according to the "X-axis direction," "Y-axis direction," and "Z-axis direction" described in the embodiments. In the embodiments, the X-axis direction is perpendicular to both the Y-axis direction and the Z-axis direction. The X-axis direction can be divided into left and right, the Y-axis direction into front and back, and the Z-axis direction into up and down.

[0040] See Figure 1 , Figure 1 A seesaw-type oscillating relay is shown, including a fixed portion 100 and an oscillating portion 200 that oscillates relative to the fixed portion 100 on a first plane. The first plane is the plane containing the motion trajectory of the oscillating portion 200 and is an abstract reference plane. This plane is perpendicular to the oscillation axis of the oscillating portion 200. Here, oscillation means that the oscillating portion 200 has no motion component in the direction of the oscillation axis, or only a small motion component caused by manufacturing / assembly errors. In this embodiment, the first plane is perpendicular to the X-axis direction.

[0041] The fixed part 100 includes a base 10, a coil assembly 20, and a static spring part 30, which are integrally formed by injection molding. The base 10 is generally rectangular, with its length direction in the Y-axis direction, its width direction in the X-axis direction, and its height direction in the Z-axis direction.

[0042] The coil assembly 20 is a prior art technology. The coil assembly 20 and the base 10 are injection molded as one piece. For example, the coil assembly 20 includes a coil frame, a U-shaped iron core and enameled wire. The coil frame includes a winding shaft extending along the Y-axis and baffles respectively wound around the two ends of the winding shaft. The coil assembly 20 is also provided with a signal terminal 22. The signal terminal 22 extends out of the bottom surface of the base 10. The U-shaped iron core passes through the coil frame and its two ends extend out of the baffles along the Z-axis. The part of the U-shaped iron core extending out of the baffles forms a magnetic pole surface 21. That is, the coil assembly 20 has two magnetic pole surfaces 21 exposed at the upper end of the base 10.

[0043] The stationary spring section 30 is provided with at least one stationary spring assembly. Each stationary spring assembly is provided with a normally open stationary contact 31, a common end 32 and a normally closed stationary contact 33 arranged sequentially along the Y-axis direction, as well as a stationary spring normally open end 34 corresponding to the normally open stationary contact 31, a stationary spring common end 35 corresponding to the common end 32 and a stationary spring normally closed end 36 corresponding to the normally closed stationary contact 33. The stationary spring normally open end 34, the stationary spring common end 35 and the stationary spring normally closed end 36 all extend out of the bottom surface of the base 10. In this embodiment, the stationary spring section 30 includes two stationary spring assemblies arranged along the X-axis direction, and the two stationary spring assemblies are symmetrically arranged.

[0044] In practical applications, the base 10, coil assembly 20, and stationary spring portion 30 are injection molded, such that at least a portion of the two normally open stationary contacts 31, two normally closed stationary contacts 33, and common terminal 32 are exposed at the upper end of the base 10. The two normally open stationary contacts 31 are located on the same side, the two normally closed stationary contacts 33 are located on the same side, and the two common terminals 32 are located in the middle of the base 10 and close to both sides of the base 10 along the X-axis. One magnetic pole surface 21 is located between the two normally open stationary contacts 31 along the X-axis, and the other magnetic pole surface 21 is located between the two normally closed stationary contacts 33 along the X-axis. The signal terminal 22, the normally open end 34 of the stationary spring, the common end 35 of the stationary spring, and the normally closed end 36 of the stationary spring all extend beyond the bottom surface of the base 10, thereby fixing the coil assembly 20 and the stationary spring portion 30 relative to the base 10. After injection molding, see [link to documentation]. Figure 1The base 10 forms a mounting groove 11, which is located between two magnetic pole surfaces 21 along the Y-axis and is used to accommodate the swing portion 200. The common end 32 forms a fitting wall 321 and a connecting wall 322, which are integrally connected. The fitting wall 321 extends along the Y-axis and is at least partially enclosed by the base 10. The outer side of the fitting wall 321 protrudes from the side of the base 10. The inner side of the connecting wall 322 fits against the base 10, while the outer side protrudes from the upper end of the base 10. In this embodiment, the connecting wall 322 is inclined relative to the Z-axis and forms an acute angle with a second plane perpendicular to the Y-axis. There is a rounded transition between the fitting wall 321 and the connecting wall 322. The base 10 has a support portion 12 corresponding to the upper end of the connecting wall 322, adapted to fit the shape of the rounded transition section 5321 described below and supporting the rounded transition section 5321. The base 10 has a clearance portion 13 integrally connected to the support portion 12. See [link to relevant documentation]. Figure 2 The clearance portion 13 is provided with a clearance ramp 131 inclined relative to the extension 531 (hereinafter referred to as extension 531) so that the extension 531 (hereinafter referred to as extension 531) is at least partially suspended from the base 10. In this embodiment, the base 10 is provided with a weld slag guide ramp 14 inclined downward from the inside to the outside corresponding to the connecting wall 322. See [link to relevant documentation]. Figure 4 The avoidance slope 131 and the slag guide slope 14 are located on both sides of the connecting wall 322, respectively.

[0045] As described above, the connecting wall 322 forms an acute angle with the second plane and is used to fix and fit with the bent section 532 described below. The second plane is perpendicular to the first plane and passes through the swing axis of the swing portion 200. The second plane is an abstract reference plane, but it always satisfies the geometric relationship of being perpendicular to the first plane and parallel to the swing axis. In this embodiment, the second plane is perpendicular to the Y-axis direction, and the angle between the connecting wall 322 and the second plane can be 5°-15°. In another embodiment, the tilt angle between the connecting wall 322 and the second plane can be 15°-30° to adapt to different stress dispersion requirements. That is, the fixing portion 100 is provided with a connecting wall 322 for fixing and fitting with the bent section 532. It can be seen that the fixing portion 100 is provided with a stationary contact (normally open or normally closed), and the stationary contact (normally open or normally closed) and the connecting wall 322 are arranged along the Y-axis direction.

[0046] See Figure 2In this embodiment, a normally open stationary contact 31 and a normally closed stationary contact 33 are provided. The connecting wall 322 is inclined from bottom to top toward the side away from the normally open stationary contact 31. The extension section 531 is located between the normally open stationary contact 31 and the connecting wall 322 along the Y-axis direction. Correspondingly, the connecting wall 322 is inclined from bottom to top toward the side closer to the normally closed stationary contact 33. The connecting wall 322 is located between the extension section 531 and the normally closed stationary contact 33 along the Y-axis direction. It should be noted that in other embodiments, only the normally open stationary contact 31 or only the normally closed stationary contact 32 may be provided. When only the normally open stationary contact 31 is provided, that is, when the stationary contact is normally open, the connecting wall 322 is inclined from bottom to top toward the side away from the normally open stationary contact 31, and the extension section 531 is located between the normally open stationary contact 31 and the connecting wall 322 along the Y-axis direction. When only the normally closed stationary contact 33 is provided, that is, when the stationary contact is normally closed, the connecting wall 322 is inclined from bottom to top toward the side close to the normally closed stationary contact 33, and the connecting wall 322 is located between the extension section 531 and the normally closed stationary contact 33 along the Y-axis direction.

[0047] See Figure 5-8 The swinging part 200 includes a number of moving springs 40 equal to the number of stationary springs, normally open moving contacts 51 corresponding to normally open stationary contacts 31, normally closed moving contacts 52 corresponding to normally closed stationary contacts 33, a connecting part 53, an armature 60, an insulator 70, and a magnet 80. The moving springs 40, armatures 60, and magnets 80 are connected as one unit through the insulator 70. The normally open moving contacts 51 and normally closed moving contacts 52 are respectively fixed to both ends of the moving springs 40 along their length. The connecting part 53 is integrally formed with the moving springs 40. The armature 60 is driven by the coil assembly 20 to swing back and forth, causing the normally open moving contacts 51 to close or open with the normally open stationary contacts 31, and the normally closed moving contacts 52 to close or open with the normally closed stationary contacts 33. That is, the swinging part 200 is provided with moving contacts corresponding to the stationary contacts, and the moving contacts and stationary contacts close or open along the Z-axis direction. The Z-axis direction is the up-down direction. The magnet 80 is closer to the coil assembly 20 than the armature 60.

[0048] The portion of the swing portion 200 other than the connecting portion 53 forms the main body of the swing portion 200. That is, the swing portion 200 includes the main body and the connecting portion 53 extending from the main body. The connecting portion 53 has a fixing portion that is fixedly connected to the fixed portion 100. The connecting portion 53 has an extension section 531 and a bent section 532. The extension section 531 extends along the extension direction of the main body, and the bent section 532 is located at the end of the extension section 531. The bent section 532 forms an angle with the extension section 531 on a first plane, and the fixing portion is located at the bent section 532. (See also...) Figure 4The extension section 531 is at least partially suspended above the base 10. The bent section 532 has an arc transition section 5321 that connects to the end of the extension section 531. The connecting part 53 also has a connecting arm 533 extending along the width direction of the moving spring 40. One end of the connecting arm 533 is integrally formed with the moving spring 40, and the other end is integrally connected with the end of the extension section 531 away from the bent section 532, and the two are located on the same plane. The bent section 532 has symmetrical notches 532 on both sides in the width direction for welding to the connecting wall 322. In this embodiment, the notches 532 are arc-shaped, but it should be understood that the notches 532 can also be other shapes, such as rectangular or V-shaped, to optimize the welding strength.

[0049] See Figure 5 The swing portion 200 has a first surface 201 facing away from the fixed portion 100; the insulator 70 is rotatably engaged with the fixed portion 100, and one of the insulator 70 and the fixed portion 100 has a rotating shaft 71, while the other has a rotating groove 15 adapted to the rotating shaft 71; the rotating shaft 71 is further away from the first surface 201 than the extension 531. Specifically, in this embodiment, the swing portion 200 has a rotating shaft 71, and the fixed portion 100 has a rotating groove 15. Preferably, in this embodiment, the insulator 70 has rotating shafts 71 extending along the X-axis direction on both sides below the connecting arm 533, and the base 10 has a rotating groove 15 extending along the X-axis. One end of the rotating groove 15 is closed, and the other end is connected to the mounting groove 11.

[0050] In this embodiment, the relay is preferably a high-frequency signal relay. In practical applications, the fixed part 100 also includes a housing 16 (see...). Figure 1 The base 10 and the shielding cover (not shown in the figure) are mounted on the outer shell 16 along the Z-axis direction. The outer shell 16 is mounted on the base 10 along the Z-axis direction and forms an accommodating space with the upper end of the base 10. Both the base 10 and the outer shell 16 are made of plastic. The swinging part 200 swings relative to the base 10 within the accommodating space, and the shielding cover is mounted on the outer shell 16 along the Z-axis direction.

[0051] In this embodiment, the main body of the swing portion 200 serves as the core structure of the swing portion 200, and the connecting portion 53 serves as the transition structure between the main body and the fixed portion 100, realizing the transmission and connection of force. The connecting portion 53 is provided with an extension section 531 and a bending section 532. The extension section 531 extends along the extension direction of the main body, and the bending section 532 is disposed at the end of the extension section 531. The bending section 532 and the extension section 531 form an angle on the first plane. The fixed part is disposed at the bending section 532. That is, the bending section 532 is not disposed on the side where the width direction of the extension section 531 is located, but is disposed at the end where the length direction of the extension section 531 is located. The arrangement of the extension section 531 and the bending section 532 is different from not having the bending section 531. The structure of section 32 increases the elasticity of the connecting part 53. The bent section 532 can absorb vibration energy, thus forming a dual structure of "rigid support - elastic buffer" for the connecting part 53. After the bent section is fixed, when the swinging part 200 swings, the extension section 531 is designed along the extension direction of the main body to maintain the consistency of the force transmission path. When the extension section 531 is subjected to force, the force of the extension section 531 will be absorbed by the bent part of the bent section 532 and will not be transmitted to the fixed part of the bent section 532. That is, the elasticity of the bent section 532 can buffer the alternating stress during the swinging process, significantly reducing the failure risk of the fixed point between the bent section 532 and the movable part, thereby ensuring the reaction force when the contact is opened and the reliable closure when the contact is closed. In addition, the angle structure between the bent section 532 and the extension section 531 can generate a preload to meet different contact pressure requirements, further ensuring the rapid opening or stable closure of the contact.

[0052] In this embodiment, the bending section 532 is provided with an arc transition section 5321 that connects to the end of the extension section 531. The arc transition avoids the stress concentration problem of right-angle bending and can further disperse stress. In addition, the arc radius is adjustable to adapt to different contact pressure requirements.

[0053] In this embodiment, the fixing part 100 is provided with a connecting wall 322 for fixing and fitting with the bent section 532. Since the connecting wall 322 fits with the bent section 532, the connecting wall 322 also forms an angle with the extension section 531 in the first plane. The connecting wall 322 also forms an angle with the second plane, which is perpendicular to the first plane and passes through the swing axis of the swing part 200. The connecting wall 322 can optimize the force direction when the bent section 532 is fixed to the connecting wall 322, thereby reducing the shear force component parallel to the fixing surface and increasing the normal pressure. This improves the bonding strength. Through the elastic buffering of the extension section 531 and the bending section 532, combined with the inclined design of the connecting wall 322, the tearing force generated by the swing is dispersed along the inclined direction to the entire fixed part 100, rather than concentrated on the bonding plane, thus avoiding stress fatigue problems. In addition, compared with the connecting wall 322 which is parallel to the second plane, the connecting part 53 and the connecting wall 322 can form a self-locking structure, making the bonding surface more conducive to bearing the swing stress, and further improving the connection stability of the bending section 532 and the connecting wall 322.

[0054] In this embodiment, when the stationary contact is a normally open stationary contact 31, the connecting wall 322 is inclined from bottom to top toward the side away from the normally open stationary contact 31. The extension section 531 is located between the normally open stationary contact 31 and the connecting wall 322 along the Y-axis. The inclined setting of the connecting wall 322 can increase the disconnection distance between the normally open stationary contact 31 and the corresponding moving contact, avoiding false triggering. When used in a high-frequency signal relay, it also increases the high-frequency signal isolation between the normally open stationary contact 31 and the corresponding moving contact. When the stationary contact is a normally closed stationary contact 33, the connecting wall 322 is inclined from bottom to top toward the side closer to the normally closed stationary contact 33. When the connecting wall 322 is located between the extension section 531 and the normally closed stationary contact 33 along the Y-axis, it can increase the... The closing pressure of the normally closed stationary contact 33 and the corresponding moving contact effectively resists accidental contact disconnection caused by external vibration or interference. When the relay closes, the normally closed stationary contact 33 will bounce back upon initial contact. A greater closing pressure can significantly shorten the bounce time and improve the response speed. When used in high-frequency signal relays, bounce can be reduced, thereby ensuring the contact stability of the normally closed stationary contact 33 and the continuity of high-frequency signal transmission. (When the moving contact bounces back, the moving and stationary contacts open, and a capacitance effect is generated between them. The characteristic impedance of the signal transmission line deviates from the expected standard value (such as 50Ω or 75Ω). Therefore, high-frequency signals will experience high-frequency signal loss when passing between the moving and stationary contacts.) In practical applications, the contact gap, contact overtravel force, and contact closing pressure can be adjusted by adjusting the tilt angle of the connecting wall 322, thereby improving the contact stability of the normally closed contact. When applied to high-frequency signal relays, the capacitance effect of the normally closed contact can be reduced, thus reducing signal loss.

[0055] In this embodiment, the integrated injection molding of the fixed part 100 improves the positional accuracy and relative stability of each functional component (such as coil, stationary contact, and common terminal 32). The stationary spring part 30 is provided with at least one stationary spring assembly. Each stationary spring assembly is provided with a normally open stationary contact 31, a common terminal 32, and a normally closed stationary contact 33 arranged sequentially along the Y-axis. The swinging part 200 is provided with a normally open moving contact 51 corresponding to the normally open stationary contact 31 and a normally closed moving contact 52 corresponding to the normally closed stationary contact 33, forming a seesaw layout, which helps to reduce swing eccentricity or additional torque, thereby achieving force balance. The connecting part 53 is provided on the moving spring 40, which is convenient for processing.

[0056] In this embodiment, the extension section 531 is at least partially suspended from the base 10. The suspended section easily absorbs the energy of the swing deformation, further reducing the swing stress transmitted to the fixed surface between the bent section 532 and the connecting wall 322, and reducing the frictional loss of the extension section 531 during swing, thus improving its lifespan and providing movement space for the swing of the connecting part 53. When used in a high-frequency signal relay, the reduced frictional loss also makes the connecting part 53 less prone to deformation and does not increase surface roughness, thereby ensuring the stability of signal transmission.

[0057] In this embodiment, the support portion 12 further reduces local stress concentration and improves the stability of the relay's operation and release process. Furthermore, by adjusting the bending radius R of the connecting portion 53 (i.e., changing the length L of the cantilever beam from the center of the bending radius to the other end of the extension section 531), the rotational torque M1 must remain constant while maintaining the same rotation range (fixed relay stroke). When R is decreased, L increases, and the suction force F required for the armature 60 to close with the core is smaller, thereby reducing the ampere-turns of the relay coil (reducing power consumption). Conversely, increasing R shortens L, increasing the required suction force F, and requiring an increase in ampere-turns to ensure suction force (but increasing power consumption). When applied to high-frequency signal relays, while ensuring the shortest transmission line distance and power consumption meets application requirements, the length of L can be changed by flexibly adjusting the value of R to achieve precise matching of suction force and reaction force during relay operation.

[0058] In this embodiment, the avoidance part 13 provides movement space for the extension section 531 to swing, avoiding additional stress caused by structural interference and improving the operational reliability of the swing part 200; in addition, the setting of the avoidance slope 131 allows the cantilever beam to rotate to a larger angle range, making the normally closed end moving and stationary contacts farther apart, thereby increasing the isolation between the normally closed end moving and stationary contacts.

[0059] In this embodiment, symmetrical notches 5322 for welding to the connecting wall 322 are provided on both sides of the bent section 532 in the width direction. These two notches 5322 are used for welding to the connecting wall 322. The arrangement of these two notches increases the welding strength and minimizes the welding contact area A between the bent section 532 and the connecting wall 322. According to the parallel plate capacitor theory (Cp=εA / d), reducing the contact area A significantly reduces the shunting effect of high-frequency signals and reduces the distributed capacitance of the welded part. This allows the characteristic impedance of the welding transmission line from the connecting part 53 to the connecting wall 322 to be precisely matched to 50Ω or 75Ω (the standard impedance value for high-frequency signals), effectively reducing the transmission loss of high-frequency signals in this welding stage. The connecting part 53 is located on the moving spring 40, which facilitates processing.

[0060] In this embodiment, the fitting wall 321 extends along the Y-axis and is at least partially wrapped by the base 10; there is an arc transition between the fitting wall 321 and the connecting wall 322. The arc transition avoids the stress concentration problem of right-angle bending and can further disperse stress. In addition, the arc radius is adjustable, and the connecting wall 322 can be adjusted by adjusting the arc radius to adapt to different contact pressure requirements.

[0061] In this embodiment, the welding slag guide slope 14 can use the height difference to guide the welding slag generated during welding to roll naturally to the outside of the relay, avoiding the accumulation of welding slag from affecting the internal operating mechanism of the relay and ensuring the reliability of the relay's long-term operation.

[0062] In this embodiment, the connecting arm 533 extends along the width direction of the moving spring 40, so that the connecting part 53 adopts a right-angle bending structure, which reduces the number of bends of the connecting part 53, reduces the capacitance effect, and makes the characteristic impedance matching of this part closer to the expected standard value (such as 50Ω or 75Ω), avoiding problems such as increased capacitance effect caused by excessive bending, and shortening the transmission path of high-frequency signals in the relay, thereby reducing the loss of high-frequency signals during transmission.

[0063] In this embodiment, in the prior art, the rotational engagement between the swinging part 200 and the fixed part 100 is accomplished by the moving spring 40 and the base 10 of the fixed part 100. The rotational engagement structure between the rotating shaft 71 and the rotating groove 15, with the rotating shaft 71 being further away from the first surface 201 than the extension section 531, can effectively prevent the surface of the moving spring 40 from deforming due to friction or force, thereby stabilizing the surface roughness of the moving spring 40 in this area, ensuring that the characteristic impedance of the signal transmission line does not drift due to contact deformation, and ultimately significantly reducing the transmission loss of high-frequency signals and improving the signal transmission reliability of the relay under complex operating conditions. Specifically, firstly, the contact fit between the rotating shaft 71 and the rotating groove 15 completely avoids direct contact between the base 10 and the moving spring 40, preventing deformation or surface roughness changes in the moving spring 40 due to force and ensuring that the characteristic impedance of the transmission line is not interfered with, thereby effectively reducing signal transmission loss during relay operation; secondly, the convex-concave structure also has a limiting function, which can precisely control the rotation range of the moving swing part 200 and significantly improve its assembly accuracy with the fixed part 100; at the same time, the tight fitting design effectively reduces the mating distance between the two, creating conditions for reducing the overall height of the relay, thereby reducing the relay's stroke and making the relay's action / release faster; thirdly, this structure allows for a smaller bending angle θ at the end of the connecting part 53 (bending section 532 and extension section 531), which reduces the risk of plastic deformation at the bending part and reduces signal transmission loss caused by deformation; more importantly, this improvement makes the contact pressure distribution of the normally closed moving and stationary contacts more uniform and the closed state more stable and reliable.
