Abstract
Description
Technical Field
[0001] The present application relates to the technical field of relays, and more specifically to a relay with a buffering noise reduction structure. Background Art
[0002] A relay is an electrical control device that triggers a step-like response in the output circuit through changes in input quantities, enabling functions such as automatic control, circuit protection, and signal switching. Relays include push-rod relays.
[0003] Patent document CN2922109Y discloses a push-rod relay comprising a housing, a coil assembly, an armature, a push rod, a movable spring, and a stationary spring. When the coil assembly is energized, the armature swings toward the coil assembly, pushing the push rod, causing the movable spring to contact the stationary spring. However, during the armature's reciprocating motion, the armature and the coil assembly come into direct contact and collide, resulting in a high level of overall noise.
[0004] In addition, patent document CN102117715B discloses a relay with an exhaust port. It should be noted that when an energized moving reed contacts a stationary reed, a brief spark discharge may occur due to bouncing or unstable contact. Although this spark is short-lived, it can cause oxidation or ablation of the contacts, generating metal vapor. When the moving and stationary reeds separate, the resulting instantaneous voltage is extremely high, breaking through the air and forming an arc, which can also cause oxidation or ablation of the contacts, generating metal vapor. The exhaust port allows the hot metal vapor to be discharged to the outside, preventing it from adhering to the yoke and, after long-term deposition on the yoke surface, increasing the contact resistance of the yoke and causing localized heating. Therefore, how to more quickly discharge the metal vapor through the exhaust port is a technical issue of concern in the industry.
[0005] Therefore, there is a demand for providing a relay with a buffer noise reduction structure that has less noise and helps metal vapor to be discharged more quickly along the exhaust port. Summary of the Invention

[0024] Schematic diagram of a relay with a buffered noise reduction structure, see Figures 1 to 8According to a preferred embodiment of the present invention, a relay with a buffered noise reduction structure includes a packaging component 10, an electromagnetic component 20 and a reed component 30.
[0025] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, the packaging component 10 includes a shell 101 and a cover 102, the shell 101 has a receiving cavity 1011, the cover 102 is connected to the shell 101 and closes the cavity opening of the receiving cavity 1011; the electromagnetic component 20 includes a coil component 201, a yoke 202, an armature 203 and a push rod 204, one end of the yoke 202 is connected to the coil component 201, the middle section of the armature 203 is swingably mounted on the end of the yoke 202 away from the coil component 201, and one end of the armature 203 is close to the end of the coil component 201 away from the yoke 202, and the push rod 204 is passed through the end of the armature 203 away from the coil component 201. 04; The reed assembly 30 includes a movable reed 301 and a static reed 302, and the static reed 302 and the movable reed 301 are fixedly mounted on the end of the cover 102 away from the coil assembly 201 and are spaced a predetermined distance apart. The end of the push rod 204 away from the armature 203 is connected to the end of the movable reed 301 away from the cover 102. The coil assembly 201 includes a coil frame 2011, an iron core 2012 and a coil winding 2013. The coil winding 2013 is wound on the coil frame 2011, and one end of the iron core 2012 passes through the coil frame 2011 and the yoke 202. The movable reed 301 and the static reed 302 both have reed pins.
[0026] It should be noted that, under normal conditions, the movable spring piece 301 is spaced a predetermined distance from the static spring piece 302. When the coil winding 2013 is energized, the end of the armature 203 facing away from the push rod 204 flips toward the iron core 2012 by a predetermined angle under the action of the magnetic force. Subsequently, the other end of the armature 203 flips toward the static spring piece 302 by a predetermined angle, and applies a horizontal thrust to the push rod 204, causing the push rod 204 to slide toward the static spring piece 302, and causing the movable spring piece 301 to bend toward the static spring piece 302 by a predetermined angle under the force, and at a certain moment, the movable spring piece 301 is in contact with the static spring piece 302, and the movable spring piece 301 and the static spring piece 302 are then conductive to each other.
[0027] In addition, if Figure 1 As shown, the electromagnetic assembly 20 further includes a reset spring 205 , one end of which is fixedly mounted on the yoke 202 , and the other end of which is connected to the armature 203 .
[0028] It should be noted that when the coil winding 2013 is energized and the armature 203 is actuated, the reset spring 205 is deformed by force. When the coil winding 2013 loses power, the reset spring 205 returns to its initial state under the action of elastic force and separates the armature 203 from the iron core 2012. At the same time, the other end of the armature 203 drives the push rod 204 to slide in the direction away from the static spring 302.
[0029] It should also be noted that in order to avoid the armature 203 from making loud noise when contacting the iron core 2012, two buffer parts 2031 are provided at one end of the armature 203 close to the coil assembly 201. The two buffer parts 2031 are respectively provided on the two sides of the armature 203. The buffer parts 2031 are connected to the armature 203, and there is a deformation buffer space between the buffer parts 2031 and the armature 203.
[0030] Specifically, in the present invention, the buffer 2031 is a single piece with its midsection bent at a predetermined angle. One end of the buffer 2031 is fixedly connected to the armature 203. When the coil winding 2013 is energized, the buffer 2031 first contacts the iron core 2012. The armature 203 can be considered to achieve soft contact with the iron core 2012 through the buffer 2031. This shortens the overall rotational travel of the armature 203, and the kinetic energy of the collision between the armature 203 and the iron core 2012 is partially converted by the buffer 2031, achieving the technical goal of reducing impact noise at the armature 203 when the coil winding 2013 is energized. Clearly, compared to the prior art, the present invention has the advantage of lower noise.
[0031] In addition, it should be noted that metal vapor may be generated when the movable spring 301 contacts or separates from the static spring 302. In order to reduce the accumulation of metal vapor on the yoke 202 and reduce the contact resistance of the yoke 202, in view of this, in the present invention, as shown in FIG. Figure 1 As shown, an exhaust port 1012 is provided on the bottom wall of the accommodating cavity 1011 , and the exhaust port 1012 is located between the reed assembly 30 and the armature 203 , so that when metal vapor is generated, the metal vapor is discharged along the exhaust port 1012 , thereby reducing the amount of metal vapor accumulated on the yoke 202 .
[0032] In addition, if Figure 1As shown, the middle section of the cover 102 has a partition 1021. The partition 1021 extends a predetermined distance from one side of the cover 102 toward the bottom wall of the accommodating cavity 1011, and the top surface of the partition 1021 is spaced a predetermined distance from the bottom wall of the accommodating cavity 1011. The provision of the partition 1021 effectively prevents metal vapor from flowing directly toward the yoke 202.
[0033] Furthermore, if Figure 4 As shown, the relay with a buffering and noise reduction structure also includes a flow guide module 40, which is arranged at one end of the exhaust port 1012 away from the reed assembly 30. The flow guide module 40 includes a first blade 4011 and a second blade 4022. When the push rod 204 moves and makes the movable reed 301 contact the static reed 302, the first blade 4011 rotates circumferentially. When the movable reed 301 separates from the static reed 302, the second blade 4022 rotates circumferentially.
[0034] It should be noted that, after the movable reed 301 contacts the stationary reed 302, the first blade 4011 rotates circumferentially. Then, when the first blade 4011 rotates circumferentially, a negative pressure zone is formed at the end of the first blade 4011 close to the partition portion 1021, and the metal vapor is guided to move toward the first blade 4011. Since the guide module 40 is provided at the end of the exhaust port 1012 away from the reed assembly 30, the metal vapor will flow toward the exhaust port 1012 under the guidance of the wind. However, since the stroke between the movable reed 301 and the stationary reed 302 is short, the first blade 4011 will stop after rotating a small number of circles. In the embodiment of the application, the number of rotations of the first blade 4011 is set to stop circumferential rotation when the metal vapor flows to the exhaust port 1012, so that the metal vapor can be discharged faster along the exhaust port 1012; in addition, when the movable reed 301 is separated from the static reed 302, the second blade 4022 rotates circumferentially, and when the push rod 204 moves away from the static reed 302 and returns to its initial state, the metal vapor is guided to the vicinity of the exhaust port 1012, so that the metal vapor can be discharged faster along the exhaust port 1012. It is obvious that compared with the prior art, the present application has the advantage of helping metal vapor to be discharged faster along the exhaust port 1012.
[0035] Furthermore, in order to realize that after the movable spring piece 301 contacts the static spring piece 302, Figure 5As shown, the first blade 4011 rotates circumferentially, the guide module 40 includes a first guide component 401, the first guide component 401 includes an outer rod body 4012, an inner rod body 4013, a rotating cylinder 4014 and a spring 4015, the outer rod body 4012 is rotatably mounted on the top of the partition part 1021, the outer rod body 4012 is provided with a gear part 40121, one side of the push rod 204 is provided with a first rack part 2041, the first rack part 2041 is engaged with the gear part 40121, the rotating cylinder 4014 is rotatably sleeved on the outer rod body 4012, the inner rod body 4013 is lifted and lowered through the outer rod The inner rod body 4013 has a limiting portion 40131 at one end close to the rotating cylinder 4014, and the rotating cylinder 4014 has a groove 40141 that cooperates with the limiting portion 40131. The other end of the inner rod body 4013 is fixedly installed with a first magnetic piece 40132, and the partition portion 1021 is fixedly installed with a second magnetic piece 4016. The first magnetic piece 40132 and the second magnetic piece 4016 are both radially magnetized and coaxially arranged in the height direction. The first blade 4011 is provided on the outer wall of the rotating cylinder 4014, and the two ends of the mainspring 4015 are respectively connected to the rotating cylinder 4014 and the outer shell 101.
[0036] It should be noted that, since the gear portion 40121 on the outer rod body 4012 is engaged with the first rack portion 2041 on one side of the push rod 204, when the coil winding 2013 is energized and causes the push rod 204 to slide toward the static spring piece 302, the outer rod body 4012 rotates circumferentially under the transmission mode of the gear rack; in addition, it should be pointed out that the inner rod body 4013 is a square column as a whole, so when the inner rod body 4013 passes through the outer rod body 4012, the circumferential rotation of the outer rod body 4012 will drive the inner rod body 4013 Synchronously rotate circumferentially; in addition, a cross-sectional shape of the limiting portion 40131 and the groove 40141 is polygonal, preferably square. When the limiting portion 40131 extends into the groove 40141, when the outer rod body 4012 rotates circumferentially, in addition to the circumferential rotation of the inner rod body 4013, the rotating cylinder 4014 follows the circumferential rotation; in addition, it should be pointed out that the magnetization of the first magnetic piece 40132 and the second magnetic piece 4016 can be two-pole or four-pole. When the magnetization of the first magnetic piece 40132 and the second magnetic piece 4016 is as follows Figure 6 When the push rod 204 moves toward the static spring piece 302 and makes the dynamic spring piece 301 contact the static spring piece 302, the outer rod body 4012 rotates exactly 180°; and when the magnetization of the first magnetic piece 40132 and the second magnetic piece 4016 is as follows Figure 7When the four poles are formed, the push rod 204 moves toward the static spring piece 302, and when the dynamic spring piece 301 contacts the static spring piece 302, the outer rod body 4012 rotates exactly 90 degrees; it should be noted that, in the initial state, that is, when the coil winding 2013 is not energized, the magnetic pole directions of the first magnetic piece 40132 and the second magnetic piece 4016 are the same, that is, the N pole of the first magnetic piece 40132 is opposite to the N pole of the second magnetic piece 4016, and the S pole of the first magnetic piece 40132 is opposite to the S pole of the second magnetic piece 4016. At this time , under the action of magnetic repulsion, the inner rod body 4013 makes the end of the inner rod body 4013 provided with the first magnetic piece 40132 be spaced a predetermined distance from the second magnetic piece 4016, and makes the limiting portion 40131 extend into the groove 40141, and when the push rod 204 slides toward the static spring piece 302, and makes the outer rod body 4012, the inner rod body 4013 and the rotating cylinder 4014 all rotate synchronously by a predetermined angle, it should be pointed out that at this time, the mainspring 4015 is retracted by the torsion force, and it should also be pointed out that when the inner rod body 40 After rotating by a predetermined angle, such as 180° in the case of two poles and 90° in the case of four poles, and making the N pole of the first magnetic piece 40132 face the S pole of the second magnetic piece 4016, and the S pole of the first magnetic piece 40132 face the N pole of the second magnetic piece 4016, the inner rod 4013 is no longer subject to the magnetic repulsion force, but moves a predetermined distance toward the direction of the second magnetic piece 4016 under the action of the magnetic attraction force, and makes the limiting portion 40131 disengage from the groove 40141. When the limiting portion 40131 disengages from the groove 40141, because The outer rod body 4012 is cylindrical as a whole, and the rotating cylinder 4014 is sleeved on the outer rod body 4012 with an inner circular hole. The rotating cylinder 4014 will rotate in the opposite direction under the elastic force of the mainspring 4015. It should also be pointed out that at this time, the dynamic reed 301 is in contact with the static reed 302, or metal vapor is generated. The rotation of the rotating cylinder 4014 driven by the mainspring 4015 will drive the first blade 4011 to rotate circumferentially and generate a negative pressure area, so as to guide the newly formed metal vapor to the vicinity of the exhaust port 1012. It is obvious that the action of the push rod 204 provides power for the rotation of the rotating cylinder 4014, and by setting the first magnetic piece 40132, the second magnetic piece 4016, the limiting portion 40131 and the groove 40141, before the push rod 204 pushes the movable spring piece 301 to contact the static spring piece 302, the mainspring 4015 is in an energy storage state, and after the movable spring piece 301 contacts the static spring piece 302, the rotating cylinder 4014 is driven to rotate circumferentially through the mainspring 4015.
[0037] Specifically, in order to realize the arrangement of the second magnetic piece 4016 and the rotation installation of the rotating cylinder 4014 on the housing 101, as shown in FIG. Figure 5 As shown, the top of the partition portion 1021 has a first rotating hole 10211 and a first mounting groove 10212, the first mounting groove 10212 extends a predetermined distance from the bottom wall of the first rotating hole 10211 toward the cover 102, the second magnetic piece 4016 is fixedly placed in the first mounting groove 10212, the outer rod body 4012 is rotatably installed in the first rotating hole 10211, the accommodating cavity 1011 is provided with a fixing rod 10111, the fixing rod 10111 is fixedly connected to the outer shell 101, the rotating cylinder 4014 is rotatably installed on the fixing rod 10111, and the two ends of the spring 4015 are respectively connected to the rotating cylinder 4014 and the fixing rod 10111.
[0038] Furthermore, in order to separate the movable spring piece 301 from the static spring piece 302, the second blade 4022 can rotate circumferentially at the moment of separation. Figure 4 As shown, a second rack portion 2042 is provided on the other side of the push rod 204, and the guide module 40 also includes a second guide component 402, and the second guide component 402 includes a gear shaft 4021, and the gear shaft 4021 is rotatably installed on the top of the partition portion 1021, and the gear portion 40121 of the gear shaft 4021 is engaged with the second rack portion 2042, and the second blade 4022 is provided on the side wall of the gear shaft 4021.
[0039] It should be noted that when the push rod 204 moves away from the static reed 302, the gear shaft 4021 rotates circumferentially under the action of the gear rack drive, driving the second blade 4022 to rotate circumferentially. It is obvious that, compared to the first deflector assembly 401, the second deflector assembly 402 does not have a delayed trigger structure. At the moment the push rod 204 moves, the gear shaft 4021 causes the second blade 4022 to rotate circumferentially to guide the metal vapor generated when the dynamic reed 301 separates from the static reed 302.
