The relay is actually an automatic switch for controlling a larger current with a smaller current. Therefore, the relay plays a role in automatic regulation, safety protection, and conversion of a circuit.

[0021] The support body is provided with a clearance groove, which penetrates the support body along the thickness direction. The support body is installed on the mounting surface of the armature and is located on one side of the connecting bracket.

[0022] The clearance groove is provided with a deformable spring structure, and at least part of the spring structure is exposed outside the clearance groove in the thickness direction of the support body, and the spring structure presses against the armature.

[0028] Optionally, the fastener is perpendicular to the mounting surface, and the extension direction of the bracket body is perpendicular to the mounting surface.

[0029] In a second aspect, embodiments of this application provide a vacuum relay, the vacuum relay including an electromagnetic component and an armature spring assembly as described in any one of the first aspects above, the armature spring assembly including a support frame, the support frame including a support body;

[0030] The electromagnetic component includes a magnetic cylinder and an electromagnetic coil. The electromagnetic coil is disposed in the magnetic cylinder. The armature abuts against the top wall of one end of the magnetic cylinder. The support body is fixedly connected to the top wall of one end of the magnetic cylinder through a side wing.

[0031] In this embodiment, one end of the bracket body of the connecting bracket is provided with a connecting part, and the other end of the bracket body is provided on the mounting surface of the armature. Therefore, when the armature spring assembly provided in this embodiment is applied to a vacuum relay, the connecting part can be connected to the transmission rod of the vacuum relay, and the armature can be abutted against the electromagnetic component of the vacuum relay. When the electromagnetic component is energized, the electromagnetic component generates magnetism, causing the armature to rotate. The armature can then drive the bracket body to move, thereby the bracket body drives the connecting part to move, which in turn drives the transmission rod to move, causing the normally open contact of the vacuum relay to close and providing normally open pressure to the normally open contact. In addition, a fixing member is provided on the mounting surface, and the bracket body is connected to the fixing member, which is equivalent to eliminating the bending structure in the related technology, so that the connecting bracket maintains greater rigidity to provide a larger normally open force value. Furthermore, the fixing member further fixes the bracket body in the extension direction of the bracket body, so that when the bracket body applies force to the transmission rod, the bracket body itself is more stable and less prone to shaking, ensuring that the bracket body can stably apply force to the transmission rod. Furthermore, the extension direction of the bracket body is perpendicular to the mounting surface of the armature. The connection between the bracket body and the fixing component allows for better control of dimensional accuracy. When the armature spring assembly is applied to a vacuum relay, with the magnetic cylinder in the vacuum relay as the reference plane, the bracket body is perpendicular to the mounting surface relative to the fixing component. This allows for better alignment of the connecting holes on the bracket relative to the reference plane, controlling the dimensional accuracy of the parts. Additionally, because the extension direction of the bracket body is perpendicular to the mounting surface, during armature movement, the armature applies force to the bracket body along its extension direction. This causes the bracket body to move perpendicular to the mounting surface and apply force to the transmission rod, preventing the extension direction of the bracket body from tilting relative to the mounting surface. Therefore, when the bracket plate drives the transmission rod, the transmission rod experiences a component force from the bracket body, avoiding the problem of insufficient normally open pressure in normally open contacts.

[0032] In addition, the armature spring assembly of other embodiments of this application has the following advantages: (1) Both ends of the fixed arm are connected to the armature, and the parts of the fixed arm other than the two ends of the fixed arm have gaps with the mounting surface, which can reduce the mass of the fixing part, which is beneficial for the armature to drive the support body to move after being subjected to force, and then drive the transmission rod to move. It can also reduce the cost of consumables while ensuring that the support body is supported. (2) The non-fixed part has a non-bending structure, which makes the non-fixed part more rigid, and thus makes the force provided by the non-fixed part greater, the transmission rod subjected to greater force, and the normally open pressure of the normally open contact of the vacuum relay greater. Moreover, in practical applications, the force value can be adjusted by adjusting the size design of the non-fixed part, so that the support body can provide the required normally open pressure. (3) The first connecting arm extends to the non-fixed part, and the second connecting arm extends to the non-fixed part. There is a first gap between the first connecting arm and the non-fixed part, and a second gap between the second connecting part and the non-fixed part. In practical applications, if it is necessary to further adjust the force value of the bracket body, the width or thickness of the non-fixed part can be adjusted to adjust the flexibility of the connecting bracket and realize the control of the force value so as to meet the design requirements of the normally open pressure.

[0047] like Figures 1 to 5 As shown, the armature spring assembly includes an armature 10 and a connecting bracket 20.

[0048] The armature 10 has a mounting surface 101, on which a fixing member 30 is provided. A connecting bracket 20 is provided on the mounting surface 101. The connecting bracket 20 includes a bracket body 21 and a connecting part 22. The connecting part 22 is provided at one end of the bracket body 21, and the other end of the bracket body 21 is provided on the mounting surface 101. The bracket body 21 is connected to the fixing member 30, and the fixing member 30 supports the bracket body 21.

[0049] In this embodiment, since one end of the bracket body 21 of the connecting bracket 20 is provided with a connecting part 22, and the other end of the bracket body 21 is provided on the mounting surface 101 of the armature 10, when the armature spring assembly provided in this embodiment is applied to the vacuum relay, the connecting part 22 can be connected to the transmission rod 300 of the vacuum relay, and the armature 10 can be abutted against the electromagnetic component 100 of the vacuum relay. When the electromagnetic component 100 is energized, the electromagnetic component 100 generates magnetism, thereby causing the armature 10 to rotate. The armature 10 can then drive the bracket body 21 to move, thereby the bracket body 21 drives the connecting part 22 to move, and the connecting part 22 drives the transmission rod 300 to move, so that the normally open contact of the vacuum relay is closed, providing normally open pressure to the normally open contact. Furthermore, a fixing member 30 is provided on the mounting surface 101, and the bracket body 21 is connected to the fixing member 30. Therefore, the fixing member 30 further fixes the bracket body 21 in the extending direction of the bracket body 21, making the bracket body 21 more stable and less prone to shaking when applying force to the transmission rod 300, ensuring that the bracket body 21 can stably apply force to the transmission rod 300. That is, in this embodiment, the connection between the bracket body 21 and the fixing member 30 is equivalent to the bracket body 21 not having a bending structure, making the bracket body 21 more rigid. The fixing member 30 supports the bracket body 21. When the armature 10 drives the bracket body 21 to move, and the bracket body 21 drives the transmission rod 300 to move through the connecting part 22, under the same force applied by the electromagnetic component 100 to the armature 10, the bracket body 21 can provide a larger force value, thereby making the transmission rod 300 more stressed, and thus increasing the normally open pressure of the normally open contact of the vacuum relay.

[0050] In addition, in this embodiment, the fastener 30 may be perpendicular to the mounting surface 101, and the extension direction of the bracket body 21 may be perpendicular to the mounting surface 101.

[0051] Since the extension direction of the bracket body 21 is perpendicular to the mounting surface 101, during the movement of the armature 10, the armature 10 applies force to the bracket body 21 along its extension direction. This causes the bracket body 21 to move perpendicular to the mounting surface 101 and apply force to the transmission rod 300, preventing the extension direction of the bracket body 21 from tilting relative to the mounting surface 101. Therefore, when the bracket body 21 drives the transmission rod 300, the transmission rod 300 experiences a component force from the bracket body 21, avoiding the problem of insufficient normally open pressure in normally open contacts. Furthermore, the fixing member 30 can be perpendicular to the mounting surface 101, allowing for better control of dimensional accuracy. When the armature spring assembly is applied in a vacuum relay, with the magnetic cylinder 110 in the vacuum relay as the reference plane, the fixing member 30 is vertically positioned on the mounting surface 101, and the bracket body 21 is also perpendicular to the fixing member 30 and the mounting surface 101. This allows for better alignment of the connecting holes on the connecting bracket 20 relative to the reference plane, controlling the dimensional accuracy of the parts.

[0052] In related technologies, the connecting bracket is connected to the mounting surface 101 of the armature 10. The connecting bracket is inclined relative to the mounting surface 101, that is, the connecting bracket is bent relative to the mounting surface 101, which makes the rigidity of the connecting bracket small. The connecting bracket is connected to the transmission rod 300. So when the armature 10 drives the connecting bracket to move, the connecting bracket will drive the transmission rod 300 to move in the direction of the armature 10. However, the connecting bracket is inclined relative to the mounting surface 101, so the actual force on the transmission rod 300 is the component of the force of the connecting bracket. Therefore, the force on the transmission rod 300 is small, resulting in a small normally open pressure of the normally open contact of the vacuum relay. In this embodiment, the bracket body 21 is connected to the fixing member 30, which is equivalent to eliminating the bending structure in the related technology. This makes the bracket body 21 more rigid, and the fixing member 30 supports the bracket body 21. As a result, the armature 10 drives the bracket body 21 to move. When the bracket body 21 drives the transmission rod 300 to move, the transmission rod 300 is subjected to the complete force of the bracket body 21, that is, not the component force of the bracket body 21. Therefore, when the armature 10 is subjected to the same force from the electromagnetic component 100, the force exerted by the bracket body 21 on the transmission rod 300 in this embodiment is greater than the force exerted by the connecting frame on the transmission rod 300 in the related technology. Thus, the bracket body 21 in this embodiment can increase the normally open pressure of the normally open contact of the vacuum relay.

[0053] In addition, in this embodiment, when the bracket body 21 is disposed on the mounting surface 101 of the armature 10, the bracket body 21 can be welded to the mounting surface 101 of the armature 10. Of course, the bracket body 21 can also be disposed on the mounting surface 101 of the armature 10 in other ways, such as by bolting the bracket body 21 to the mounting surface 101. For another example, the bracket body 21 may not be connected to the mounting surface 101, but the bracket body 21 may be disposed on the mounting surface 101 by a fastener 30. This embodiment does not limit the scope of this embodiment.

[0054] In addition, in some embodiments, the bracket body 21 includes a fixed part 2101 and a non-fixed part 2102; the fixed part 2101 is connected to the fastener 30, the area between the fixed part 2101 and the connecting part 22 is the non-fixed part 2102, the connecting part 22 is at least partially connected to the non-fixed part 2102, and the non-fixed part 2102 has a non-bending structure.

[0055] Since the connecting part 22 is connected to the non-fixed part 2102, after the connecting part 22 is connected to the transmission rod 300, force is applied to the connecting part 22 through the non-fixed part 2102, and then to the transmission rod 300. Because the non-fixed part 2102 has a non-bending structure, its rigidity is high, resulting in a larger force provided by the non-fixed part 2102. This causes the transmission rod 300 to experience greater force, leading to a higher normally open pressure on the normally open contact 002 of the vacuum relay. Furthermore, in practical applications, the force value can be adjusted by modifying the dimensions of the non-fixed part 2102, thereby allowing the bracket body 21 to provide the required normally open pressure.

[0056] It should be noted that the dimensions of the non-fixed part 2102 include its width, thickness, etc.

[0057] In addition, in the embodiments of this application, a non-bending structure refers to a plate structure that extends in the same direction.

[0058] Furthermore, in this embodiment, the fixing part 2101 is the area formed after being connected to the fixing member 30, and the fixing part 2101 is a non-movable area to provide stable support for the non-fixed part 2101. For example, as Figure 3 As shown, Figure 3 The part circled within the square dashed box is the fixed center part 21011. Figure 3 The part circled by the dashed box is the fixing part 2101.

[0059] In addition, in some embodiments, the fixing member 30 includes a fixing arm, both ends of which are connected to the armature 10, and the portion of the fixing arm other than the two ends of the fixing arm has a gap with the mounting surface 101; at least a portion of the fixing arm is connected to the bracket body 21.

[0060] Since both ends of the fixing arm are connected to the armature 10, and the parts of the fixing arm other than the ends have gaps with the mounting surface 101, the mass of the fixing member 30 can be reduced. This avoids the problem that the fixing member 30 is a block or plate structure, which would increase its mass and make it difficult for the armature 10 to move when the electromagnetic component 100 in the vacuum relay applies force to it due to the large mass of the fixing member 30. Furthermore, at least part of the fixing arm is connected to the bracket body 21, so the bracket body 21 can be supported by the fixing arm, ensuring that the bracket body 21 is relatively stable when moving the transmission rod 300. In other words, by connecting both ends of the fixing arm to the mounting surface 101, and ensuring that the parts of the fixing arm other than the ends have gaps with the mounting surface 101, not only is the bracket body 21 supported and stabilized, but the mass of the fixing member 30 is also reduced. This facilitates the movement of the bracket body 21 under force, which in turn moves the transmission rod 300. In addition, the fixed arm, except for the two ends, has a gap with the mounting surface 101, which can reduce the cost of consumables while ensuring that the bracket body 21 is supported.

[0061] Furthermore, when the fixed arm is a one-piece molded structure, its manufacturing process can utilize only a single armature plate, directly cutting and folding it to form the fixed arm. This avoids multiple processing steps and reduces material consumption. Additionally, the one-piece molded structure of the fixed arm also results in better connection strength.

[0062] Additionally, in some embodiments, such as Figure 1 As shown, the fixed arm includes a first sub-arm 31, a second sub-arm 32, a third sub-arm 33, a fourth sub-arm 34, and a fifth sub-arm 35; the first sub-arm 31, the second sub-arm 32, the third sub-arm 33, the fourth sub-arm 34, and the fifth sub-arm 35 are connected in sequence, and one end of the first sub-arm 31 is connected to the mounting surface 101, and one end of the fifth sub-arm 35 is connected to the mounting surface 101. The extension direction of the first sub-arm 31 is perpendicular to the mounting surface 101, and the extension direction of the fifth sub-arm 35 is perpendicular to the mounting surface 101. The second sub-arm 32, the third sub-arm 33, and the fourth sub-arm 34 all have gaps with the mounting surface 101, and at least one of the first sub-arm 31, the second sub-arm 32, the third sub-arm 33, the fourth sub-arm 34, and the fifth sub-arm 35 is connected to the bracket body 21.

[0063] Since one end of the first sub-arm 31 is connected to the mounting surface 101 and one end of the fifth sub-arm 35 is connected to the mounting surface 101, and the extension direction of the first sub-arm 31 is perpendicular to the mounting surface 101, and the extension direction of the fifth sub-arm 35 is perpendicular to the mounting surface 101, it is equivalent to the first sub-arm 31 and the fifth sub-arm 35 of the fixed arm being connected to the mounting surface 101, and the second sub-arm 32, the third sub-arm 33 and the fourth sub-arm 34 all having gaps with the mounting surface 101. This can effectively reduce the mass of the fixing member 30 and increase the number of parts on the fixed arm that are connected to the bracket body 21. That is, at least one of the first sub-arm 31, the second sub-arm 32, the third sub-arm 33, the fourth sub-arm 34 and the fifth sub-arm 35 can be connected to the bracket body 21, thereby facilitating the connection between the bracket body 21 and the fixed arm, and the bracket body 21 can be better supported.

[0064] It should be noted that the third sub-arm 33 can be connected to the support body 21, which means the support body 21 is relatively small and only connected to one sub-arm. Alternatively, the second sub-arm 32, the third sub-arm 33, and the fourth sub-arm 34 can be connected to the support body 21 simultaneously, which means the support body 21 is relatively large and can be connected to three sub-arms. Of course, the first sub-arm 31, the second sub-arm 32, the third sub-arm 33, the fourth sub-arm 34, and the fifth sub-arm 35 can also be connected to the support body 20 simultaneously. This embodiment of the application does not limit the specific implementation of these embodiments.

[0065] Of course, in this embodiment, the fixed arm may also include only one sub-arm, in which case the shape of the fixed arm may be arc-shaped or semi-circular. The fixed arm may also include six sub-arms, which are connected sequentially. The specific shape of the fixed arm is not limited in this embodiment.

[0066] In some embodiments, the fastener 30 and the armature 10 are integrally formed. This design enhances the strength of the fastener 30 and the armature 10, thereby ensuring better support of the fastener 30 for the bracket body 21. The fastener 30 and the armature 10 can be directly cast into an integral structure using die casting or casting processes.

[0067] It should be noted that when the fixing component 30 includes a fixing arm, which includes a first sub-arm 31, a second sub-arm 32, a third sub-arm 33, a fourth sub-arm 34, and a fifth sub-arm 35, the fixing arm and the armature 10 can be directly cast into an integral structure by die casting or casting process.

[0068] Of course, when the fixing member 30 includes a fixing arm, both ends of the fixing arm can also be fixed to the armature 10 by welding, or the two ends of the fixing arm can be connected to the armature 10 by bolts, pins, or other connecting parts. This embodiment of the present application does not limit this. The two ends of the fixing arm can be connected to the mounting surface 101 of the armature 10; alternatively, the two ends of the fixing arm can be connected to the side of the armature 10. This embodiment of the present application does not limit this.

[0069] In addition, in the embodiments of this application, the fastener 30 can also be a plate structure or a block structure. The specific shape of the fastener 30 is not limited in the embodiments of this application.

[0070] Additionally, in some embodiments, such as Figure 2 and Figure 3 As shown, the fixing part 2101 includes a fixing middle part 21011, a first connecting arm 40 and a second connecting arm 50. The fixing middle part 21011 has a first side surface 211 and a second side surface 212. The first side surface 211 is connected to the first connecting arm 40, and the second side surface 212 is connected to the second connecting arm 50. The extension direction of the first connecting arm 40 and the extension direction of the second connecting arm 50 are both parallel to the extension direction of the bracket body 21. The first connecting arm 40 and the second connecting arm 50 are both connected to the fixing member 30.

[0071] Since the extension directions of both the first connecting arm 40 and the second connecting arm 50 are parallel to the extension direction of the bracket body 21, it is equivalent to both the extension directions of the first connecting arm 40 and the second connecting arm 50 being perpendicular to the mounting surface 101. Furthermore, since both the first connecting arm 40 and the second connecting arm 50 are connected to the fixing member 30, the connection between the bracket body 21 and the fixing member 30 is further strengthened, improving the stability of the bracket body 21.

[0072] In addition, along the direction from the support body 21 to the armature 10, a portion of the first connecting arm 40 protrudes from the support body 21, and a portion of the second connecting arm 50 protrudes from the support body 21. The portion of the first connecting arm 40 protruding from the support body 21 engages with the side of the armature 10, and the portion of the second connecting arm 50 protruding from the support body 21 engages with the side of the armature 10.

[0073] With this configuration, the first connecting arm 40 and the second connecting arm 50 clamp the armature 10, allowing the armature 10 to engage with both the first connecting arm 40 and the second connecting arm 50. This enables the bracket body 21 to be further connected to the armature 10 via the first connecting arm 40 and the second connecting arm 50, ensuring greater stability of the bracket body 21 relative to the armature 10. Furthermore, when the connecting bracket 20 needs to engage with the armature 10, the protruding portion of the first connecting arm 40 and the protruding portion of the second connecting arm 50 facilitates accurate positioning and engagement with the armature 10. Specifically, the portion of the first connecting arm 40 protruding from the bracket body 21 engages with the side of the armature 10, and the portion of the second connecting arm 50 protruding from the bracket body 21 engages with the side of the armature 10, thus enabling better alignment and welding fixation in subsequent applications.

[0074] It should be noted that when the fixing component 30 includes a fixing arm, and the fixing arm includes a first sub-arm 31, a second sub-arm 32, a third sub-arm 33, a fourth sub-arm 34, and a fifth sub-arm 35, the first sub-arm 31 is connected to the first connecting arm 40, and the fifth sub-arm 35 is connected to the second connecting arm 50. The first sub-arm 31 can be welded to the first connecting arm 40, or it can be connected using bolts, pins, or other connecting components. Similarly, the fifth sub-arm 35 can be welded to the second connecting arm 50, or it can be connected using bolts, pins, or other connecting components.

[0075] Of course, in the embodiments of this application, the non-fixed part 2102 can also be connected to the fixing member 30 to form a fixation.

[0076] Additionally, in some embodiments, such as Figure 2 As shown, the first connecting arm 40 extends to the non-fixed portion 2102, and the second connecting arm 50 extends to the non-fixed portion 2102. A first gap exists between the first connecting arm 40 and the non-fixed portion 2102, and a second gap exists between the second connecting portion 22 and the non-fixed portion 2102. This arrangement effectively makes the width of the bracket body 21 smaller than the distance between the first connecting arm 40 and the second connecting arm 50, and the width of the bracket body 21 equal to the distance between the first side 211 and the second side 212. This avoids the problem of the first connecting arm 40 connecting to the first side 211 and the second connecting arm 50 connecting to the second side 212, which would otherwise significantly increase the mass of the components on the armature 10. Furthermore, both the first connecting arm 40 and the second connecting arm 50 are connected to the fixed arm, thus securing the bracket body 21. In practical applications, if further adjustment of the force value of the bracket body 21 is required, the width or thickness of the non-fixed portion 2102 can be adjusted to regulate the flexibility of the connecting bracket 20, thereby controlling the force value and meeting the design requirements for normally open pressure.

[0077] Additionally, in some embodiments, such as Figure 4As shown, the armature 10 has a support surface 102 facing away from the mounting surface 101. The support surface 102 includes a first sub-surface 1021 and a second sub-surface 1022. The first sub-surface 1021 and the second sub-surface 1022 have an included angle, and the second sub-surface 1022 is parallel to the mounting surface 101.

[0078] Since there is an angle between the first sub-surface 1021 and the second sub-surface 1022, and the second sub-surface 1022 is parallel to the mounting surface 101, when the electromagnetic component 100 of the vacuum relay is energized and attracts the armature 10, the second sub-surface 1022 can come into contact with the electromagnetic component 100, and the second sub-surface 1022 and the electromagnetic component 100 can make close contact. When the electromagnetic component 100 is de-energized, the first sub-surface 1021 comes into contact with the electromagnetic component 100, so that the armature 10 can move relative to the electromagnetic component 100. Thus, the armature 10 can cause the bracket body 21 to drive the transmission rod 300 to move through the connecting part 22, so that the vacuum relay can switch between normally open and normally closed. By setting an angle between the first sub-surface 1021 and the second sub-surface 1022, and making the second sub-surface 1022 parallel to the mounting surface 101, it can be ensured that the armature 10 abuts against the electromagnetic component 100, and the magnetic gap of the magnetic circuit can be guaranteed by the angle between the first sub-surface 1021 and the second sub-surface 1022, thereby stabilizing the magnetic gap of the vacuum relay, improving the consistency of the magnetic gap, and thus facilitating the switching of the vacuum relay between normally open and normally closed.

[0079] Additionally, in some embodiments, such as Figure 5 As shown, the armature spring assembly also includes a support frame 60, which includes: a support body 61; a clearance groove 611 is provided on the support body 61, and the clearance groove 611 penetrates the support body 61 along the thickness direction of the support body 61, and the support body 61 is installed on the armature 10; a deformable spring structure 62 is provided in the clearance groove 611, and at least a portion of the spring structure 62 is exposed in the clearance groove 611 in the thickness direction of the support body 61, and the spring structure 62 presses against the armature 10.

[0080] Because the support body 61 is provided with a relief groove 611, which extends through the support body 61 along its thickness direction, the relief groove 611 effectively forms an installation space. A deformable spring structure 62 can then be installed in this space. Specifically, a deformable spring structure 62 is installed in the relief groove 611, with at least a portion of the spring structure 62 exposed in the thickness direction of the support body 61. This allows the spring structure 62 to abut against the armature 10 and exert force on it, thus compressing the armature 10. Furthermore, the deformability of the spring structure 62 prevents excessive rigidity of the tail bulge of the support frame 60. When the armature spring assembly is applied to a vacuum relay, the deformable nature of the spring structure 62 reduces the operating voltage of the vacuum relay, preventing problems such as high operating voltage.

[0081] It should be noted that, in this embodiment, the reed structure 62 can be made of metal, as long as it is ensured that the reed structure 62 is deformable. For example, the reed structure 62 can be made of copper.

[0082] In addition, in this embodiment, the reed structure 62 may be connected to the wall of the clearance groove 102; of course, the reed structure 62 may also not be connected to the wall of the clearance groove 102. This embodiment does not limit the specific connection in this regard.

[0083] Additionally, in some embodiments, such as Figure 5 As shown, the reed structure 62 may include at least one first bending portion 621 and at least one second bending portion 622. The bending direction of the first bending portion 621 is opposite to that of the second bending portion 622. The first bending portion 621 and the second bending portion 622 are alternately arranged and connected to each other. Along the thickness direction of the support body 61, the support body 61 has a first surface and a second surface facing away from each other. The first bending portion 621 protrudes from the first surface, and the second bending portion 622 protrudes from the second surface. The second bending portion 622 presses against the armature 10.

[0084] Since the bending direction of the first bending portion 621 is opposite to that of the second bending portion 622, and the first bending portion 621 and the second bending portion 622 are alternately arranged and connected to each other, the first bending portion 621 and the second bending portion 622 can deform due to the bending action. Furthermore, the first bending portion 621 protrudes from the first surface of the support body 61, and the second bending portion 622 protrudes from the second surface of the support body 61. Therefore, when the support body 61 is installed on the armature 10, the portion of the second bending portion 622 exposed in the clearance groove 611 can abut against the armature 10, and the second bending portion 622 can apply force to the armature 10. In other words, by providing the first bending portion 621 and the second bending portion 622, the deformation of the spring structure 62 can be facilitated, and the force applied by the spring structure 62 to the armature 10 can be ensured.

[0085] It should be noted that the number of first bends 621 and second bends 622 can be set according to actual needs. For example, when there is only one first bend 621 and one second bend 622, the first bend 621 and the second bend 622 form an S-shaped structure. Alternatively, when there are two first bends 621 and two second bends 622, the first bend 621 and the second bend 622 form a wave-shaped structure. The number of first bends 621 and second bends 622 is not limited in this embodiment. However, to facilitate processing and avoid making the support frame 60 too large, the number of first bends 621 and second bends 622 can both be set to one.

[0086] Additionally, one end of the first bend 621 can be connected to the groove wall of the clearance groove 611, ensuring that the spring structure 62 is connected to the groove wall of the clearance groove 611. This prevents the spring structure 62 from detaching from the clearance groove 611 when it abuts against the armature 10. Of course, the first bend 321 may not be connected to the groove wall of the clearance groove 611.

[0087] In addition, along the first direction X, side wings 63 are respectively provided on opposite sides of the support body 61, and the clearance groove 611 is located between the two side wings 63. Both side wings 63 protrude from the support body 61 along the thickness direction of the support body 61, and both side wings 63 protrude from the support body 61 in the same direction. The two side wings 63 cooperate with the armature 10.

[0088] Since both side wings 63 protrude from the support body 61 along the thickness direction of the support body 61, and both side wings 63 protrude from the support body 61 in the same direction, after the support body 61 is installed on the armature 10, one side wing 63 is located on one side of the armature 10, and the other side wing 63 is located on the other side of the armature 10. Thus, the two side wings 63 will cooperate with the armature 10, thereby limiting the support body 61 in the direction from one side wing 63 to the other side wing 63, and preventing the support body 61 from easily wobbling relative to the armature 10 in the direction from one side wing 63 to the other side wing 63.

[0089] In addition, in this embodiment, a pressing groove 1011 can be provided on the mounting surface 101 of the armature 10. The plane where the bottom of the pressing groove 1011 is located can be parallel to the first sub-surface 1021. The pressing groove 1011 allows the spring structure 62 to press against the armature 10. That is, the spring structure 62 presses against the armature 10, so that when the electromagnetic component 100 of the vacuum relay is energized, the electromagnetic component 100 attracts the armature 10, so that the second sub-surface 1022 of the armature 10 abuts against the electromagnetic component 100. When the electromagnetic component 100 of the vacuum relay is de-energized, the spring structure can press against the armature 10, so that the first sub-surface 1021 of the armature 10 abuts against the electromagnetic component 100. When the spring structure 62 presses against the armature 10, the pressing point of the spring structure 62 on the armature 100 is consistent each time, so that after the electromagnetic component 100 is de-energized, the armature 10 is stabilized by the squeezing force of the spring structure 62.

[0090] In addition, in this embodiment, along the thickness direction of the armature 10, the pressing groove 1011 is positioned opposite to the first sub-surface 1021, and the spring structure 62 abuts against the bottom of the pressing groove 1011. The pressing groove 1011 and the first sub-surface 1021 are positioned opposite each other, which means that the position where the clamping member applies force to the armature 10 is opposite to the first sub-surface 1021. This ensures that when the electromagnetic component 100 of the vacuum relay is de-energized, the clamping member applies force to the armature 10, ensuring that the first sub-surface 1021 contacts the top wall of one end of the electromagnetic component 100.

[0091] In addition, in this embodiment, there may be a gap between the support frame 60 and the connecting bracket 20, which is equivalent to the support frame 60 and the connecting bracket 20 being separated from each other. Of course, the support frame 60 can also be connected to the connecting bracket 20. In addition, a connecting boss 1012 can also be provided on the mounting surface 101, and the connecting boss 1012 is connected to the support frame 60.

[0092] Additionally, in some embodiments, such as Figure 2 As shown, the extending direction of the connecting part 22 is perpendicular to the extending direction of the support body 21. With this arrangement, when the support body 21 moves, the support body 21 can effectively drive the transmission rod 300 to move through the connecting part 22.

[0093] It should be noted that a connecting hole 221 may be provided on the connecting part 22, and the connecting part 22 is connected to the transmission rod 300 through the connecting hole 221.

[0094] In some embodiments, the support body 61 has a first mounting portion 610 at the location of the clearance groove 611, and the first mounting portion 610 is connected to the armature 10. The spring structure 62 is located on the first side of the first mounting portion 610, and the connecting frame 20 is located on the second side of the first mounting portion 610, with the first side and the second side facing away from each other. With this arrangement, it is equivalent to the spring structure 62 being located on the same side of the fixed position of the first mounting portion 610 on the armature 10 and the fixed position of the connecting frame 20 on the armature 10. That is, it is equivalent to the spring structure 62 being located on the same side of the fixed end of the armature 10 that fixes the first mounting portion 610 and the fixed end of the connecting frame 20. This makes the spring structure 62 located on the same side of the two fixed ends of the armature 10. Therefore, compared with the U-shaped bend between the two fixed ends in the related art, the armature 10 spring assembly in this application can effectively prevent the armature 10 from moving back and forth. The armature spring assembly in this application can effectively prevent the armature 10 from moving back and forth. That is, even if the spring structure 62 is deformed, it will not affect the back and forth movement of the armature 10. Furthermore, the side wing 63 is fixed to the top wall of one end of the magnetic cylinder 110, thereby further integrating the entire assembly through the side wing 63, preventing the armature 10 from moving back and forth, and preventing the entire assembly from moving back and forth.

[0095] This application provides a vacuum relay, such as... Figures 6 to 8 As shown, the vacuum relay includes an electromagnetic component 100 and an armature reed assembly as described in any of the above embodiments; the armature 10 abuts against the electromagnetic component 100.

[0096] It should be noted that the vacuum relay may also include a housing 200, and normally open contact 002 and normally closed contact 001 may be disposed in the housing 200. The electromagnetic component 100 may include a magnetic cylinder 110 and an electromagnetic coil 120. The electromagnetic coil 120 is disposed in the magnetic cylinder 110. The armature 10 abuts against the top wall of one end of the magnetic cylinder 110. The support body 61 is fixedly connected to the top wall of one end of the magnetic cylinder 110 through a side wing 63, that is, the side wing 63 is fixed to the top wall of one end of the magnetic cylinder 110. The transmission rod 300 is disposed in the housing 200 and is connected to the connecting part 22. When the electromagnetic coil 120 is energized, it generates magnetism, causing the armature 10 to move. The second sub-face 1022 of the armature 10 abuts against the top wall of one end of the magnetic cylinder 110. At the same time, the transmission rod 300 moves to the normally open contact 002, making the vacuum relay normally open. When the electromagnetic coil 120 is de-energized, the armature 10 resets. Since the first sub-face 1021 of the armature 10 abuts against the outer wall of one end of the magnetic cylinder 110, the transmission rod 300 moves to the normally closed contact 001, making the vacuum relay normally closed.

[0097] It should be noted that the normally open pressure in this embodiment is the pressure that can close the normally open contact 002 and keep the contact closed, while the normally closed pressure in this embodiment is the pressure that can close the normally closed contact 001 and keep the contact closed.
