Technical Field

[0001] This application belongs to the field of vacuum relays, specifically relating to a support frame, an armature spring assembly, and a vacuum relay. Background Technology

[0002] In the electrical engineering industry, relays are widely used as control devices. They have a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and are typically used in automatic control circuits. A relay is essentially an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] In related technologies, the support frame in a vacuum relay is connected to the armature, and the support frame can drive the armature to move. However, in these technologies, the bulge at the tail of the support frame is too rigid and not easily deformed, resulting in a high operating voltage for the vacuum relay. Utility Model Content

[0026] Thirdly, embodiments of this application provide a vacuum relay, the vacuum relay including an electromagnetic component and a support frame as described in any one of the first aspects above;

[0027] The electromagnetic component includes a magnetic cylinder and an electromagnetic coil. The electromagnetic coil is disposed in the magnetic cylinder, and the support frame is disposed on the top wall of one end of the magnetic cylinder.

The clamping member and the side wings are located on the first side of the first mounting part, and the connecting frame is located on the second side of the first mounting part. The first side and the second side are opposite to each other.

[0032] In this embodiment, since the support body is provided with a clearance groove that extends through the support body along its thickness direction, the clearance groove effectively forms an installation space. A deformable clamping member can then be installed in this installation space. Specifically, a deformable clamping member is installed in the clearance groove, with at least a portion of the clamping member exposed in the thickness direction of the support body. This allows the support body to be mounted on the armature of the vacuum relay when the support frame is used. Because the clamping member is exposed in the clearance groove, it is deformable, thus abutting against the armature and applying force to it, thereby clamping the armature. Furthermore, the deformable clamping member prevents the tail bulge of the support frame from having excessive rigidity. That is, in the embodiments of this application, by providing a clearance groove on the bracket body and a deformable clamping member in the clearance groove, at least part of the clamping member is exposed outside the clearance groove in the thickness direction of the bracket body, so that when the bracket body is installed on the armature, the clamping member can abut against the armature and apply force to the armature, and the clamping member is deformable, so that the clamping member can deform under force, avoiding the large rigidity of the tail bulge of the support frame which is not easy to deform. Thus, once the support frame is applied to the vacuum relay, the deformable characteristic of the clamping member can reduce the operating voltage of the vacuum relay and avoid the problem of high operating voltage of the vacuum relay.

[0033] In addition, the support frame of other embodiments of this application has the following advantages: (1) A first mounting part is provided on the support body, which facilitates the connection between the support body and the armature, and thus facilitates the installation of the support body on the armature. (2) Side wings are provided on opposite sides of the support body, and the clearance groove is located between the two side wings. Both side wings protrude from the support body along the thickness direction of the support body, so that when the support body is installed on the armature, the side wings can cooperate with the armature, increasing the cooperation points between the support body and the armature, facilitating the cooperation between the support body and the armature, and further limiting the position of the support body, avoiding the problem of easy movement of the support body relative to the armature.

[0049] like Figures 1 to 7 As shown, the support frame 100 includes: a support body 10.

[0050] The bracket body 10 is provided with a clearance groove 101, which extends through the bracket body 10 along the thickness direction of the bracket body 10. The bracket body 10 is used to install the armature 200. A deformable clamping member 20 is provided in the clearance groove 101, and at least part of the clamping member 20 is exposed outside the clearance groove 101 in the thickness direction of the bracket body 10. The clamping member 20 is used to press the armature 200.

[0051] In this embodiment, since the bracket body 10 is provided with a relief groove 101, which extends through the bracket body 10 along its thickness direction, the relief groove 101 effectively forms an installation space. A deformable clamping member 20 can then be installed in this installation space. Specifically, a deformable clamping member 20 is installed in the relief groove 101, with at least a portion of the clamping member 20 exposed in the relief groove 101 along the thickness direction of the bracket body 10. This allows the bracket body 10 to be installed on the armature 200 in the vacuum relay when the support frame 100 is used. Because the clamping member 20 is exposed in the relief groove 101, it is deformable, thus abutting against the armature 200 and applying force to it, thereby clamping the armature 200. Furthermore, the deformability of the clamping member 20 prevents the tail bulge of the support frame 100 from having excessive rigidity. That is, in this embodiment of the application, by providing a clearance groove 101 on the bracket body 10, and providing a deformable clamping member 20 in the clearance groove 101, at least part of the clamping member 20 is exposed outside the clearance groove 101 in the thickness direction of the bracket body 10, so that when the bracket body 10 is installed on the armature 200, the clamping member 20 can abut against the armature 200 and apply force to the armature 200, and the clamping member 20 is deformable, so that the clamping member 20 can be deformed under force, avoiding the problem that the tail bulge of the support frame 100 is too rigid and not easy to deform. So that once the support frame 100 is applied to the vacuum relay, the deformable characteristic of the clamping member 20 can reduce the operating voltage of the vacuum relay and avoid the problem of high operating voltage of the vacuum relay.

[0052] In related technologies, the support frame 100 includes a support body 10. A U-shaped bending structure is provided in the middle of the support body 10, and a connecting protrusion is provided at the tail of the support body 10. The U-shaped bending structure connects to the connecting protrusion, which abuts against the armature 200. The support body 10 has mounting holes, through which it is mounted on the armature 200. During the energization and de-energization of the electromagnetic component 300 in the vacuum relay, the connecting protrusion needs to abut against the armature 200 and exert force on it. However, the connecting protrusion is rigid and not easily deformed, resulting in a large pressure exerted by the connecting protrusion on the armature. Consequently, the normally closed contact pressure is high, leading to a larger energizing voltage for the electromagnetic component 300 to provide a greater operating voltage. In this embodiment, by providing a clearance groove 101 on the bracket body 10, and providing a deformable clamping member 20 in the clearance groove 101, with at least a portion of the clamping member 20 exposed in the thickness direction of the bracket body 10, it is equivalent to providing a deformable clamping member 20 at the tail of the bracket body 10. Furthermore, the U-shaped bending structure and connecting protrusion in related technologies are eliminated. Therefore, when the bracket body 10 is installed on the armature 200, the clamping member 20 can abut against the armature 200 and move towards the armature. A force of 200 is applied, and the clamping member 20 is deformable, thus the clamping member 20 can deform under force. The deformable clamping member 20 can reduce rigid interference and control the pressure applied to the armature 200 as needed, i.e., control the pressure of the normally closed contact. This avoids the support frame 100's connecting protrusion being too rigid and difficult to deform. Therefore, once the support frame 100 is applied to a vacuum relay, the deformable characteristic of the clamping member 20 can reduce the operating voltage of the vacuum relay, avoiding the problem of high operating voltage. In other words, setting a deformable clamping member 20 not only meets the product's requirements for normally closed contacts but also reduces the operating voltage.

[0053] It should be noted that, in this embodiment, the clamping member 20 can be made of metal, as long as it is deformable. For example, the clamping member 20 can be made of copper.

[0054] In addition, in this embodiment, the clamping member 20 may be connected to the wall of the clearance groove 102; of course, the clamping member 20 may also not be connected to the wall of the clearance groove 102. This embodiment does not limit the specific connection in this regard.

[0055] In addition, in this embodiment, the clearance groove 102 can penetrate one side wall of the support body 10, that is, the clearance groove 102 extends to one side wall of the support body 10. Of course, the clearance groove 102 can also penetrate only along the thickness direction of the support body 10, that is, the clearance groove 102 does not extend to one side wall of the support body 10. The specific arrangement of the clearance groove 102 is not limited in this embodiment.

[0056] In addition, in some embodiments, the clamping member 20 may include at least one first bending portion 21 and at least one second bending portion 22, the bending direction of the first bending portion 21 being opposite to the bending direction of the second bending portion 22, the first bending portion 21 and the second bending portion 22 being alternately arranged and connected to each other; along the thickness direction of the bracket body 10, the bracket body 10 has a first surface 11 and a second surface 12 facing away from each other, the first bending portion 21 protruding from the first surface 11, the second bending portion 22 protruding from the second surface 12, and the second bending portion 22 being used to press the armature 200.

[0057] Since the bending direction of the first bending portion 21 is opposite to that of the second bending portion 22, and the first bending portion 21 and the second bending portion 22 are alternately arranged and connected to each other, the first bending portion 21 and the second bending portion 22 can deform due to the bending action. In addition, the first bending portion 21 protrudes from the first surface 11 of the bracket body 10, and the second bending portion 22 protrudes from the second surface 12 of the bracket body 10. Therefore, when the bracket body 10 is installed on the armature 200, the portion of the second bending portion 22 exposed in the relief groove 101 can abut against the armature 200, and the second bending portion 22 can exert force on the armature 200. By providing a first bend 21 and a second bend 22, the clamping member 20 can be easily deformed, and the clamping member 20 can be ensured to apply force to the armature 200. Furthermore, the presence of at least one first bend 21 and at least one second bend 22 is equivalent to allowing multiple bends to share the deformation, avoiding stress on a single deformation point, thereby reducing the stress on each bend and lowering the risk of plastic deformation of each bend.

[0058] It should be noted that the number of the first bending portion 21 and the number of the second bending portion 22 can be set according to actual needs. For example, when the number of the first bending portion 21 and the number of the second bending portion 22 are both one, the first bending portion 21 and the second bending portion 22 form an S-shaped structure. As another example, when the number of the first bending portion 21 is two and the number of the second bending portion 22 is two, the first bending portion 21 and the second bending portion 22 form a wave-shaped structure. The number of the first bending portion 21 and the number of the second bending portion 22 are not limited in this embodiment. However, to facilitate processing and avoid making the support frame 100 too large, the number of the first bending portion 21 and the number of the second bending portion 22 can both be set to one.

[0059] In addition, in this embodiment, one end of the first bend 21 can be connected to the wall of the clearance groove 101. This ensures that the clamping member 20 is connected to the wall of the clearance groove 101, preventing the clamping member 20 from detaching from the clearance groove 101 when it abuts against the armature 200. Of course, the first bend 21 may not be connected to the wall of the clearance groove 101. This embodiment does not limit this aspect.

[0060] In some embodiments, the clamping member 20 and the support body 10 are integrally formed. This design enhances the strength of both the clamping member 20 and the armature 200 support body 10, thereby ensuring that the clamping member 20 is less likely to separate from the support body 10 and that the clamping member 20 provides a good compressive effect on the armature 200. The clamping member 20 and the support body 10 can be directly cast into an integral structure using die casting or casting processes.

[0061] It should be noted that when the clamping member 20 includes a first bent portion 21 and a second bent portion 22, one first bent portion 21 is connected to the groove wall of the relief groove 101. In this case, the first bent portion 21, the second bent portion 22 and the bracket body 10 can be integrated into a single structure. That is, the first bent portion 21, the second bent portion 22 and the bracket body 10 can be cast into a single structure by die casting or casting process.

[0062] Of course, in this embodiment, the clamping member 20 can also be connected to the wall of the clearance groove 101 in other ways, such as by welding. This embodiment does not limit the method of connection between the clamping member 20 and the wall of the clearance groove 101. Alternatively, the clamping member 20 may not be connected to the wall of the clearance groove 101, i.e., the first bent portion 101 may not be connected to the wall of the clearance groove 101. In this case, the clamping member 20 can be a separate component. This embodiment does not limit the specific method of connection.

[0063] In addition, in this embodiment, the clamping member 20 is not limited to including the first bent portion 21 and the second bent portion 22. That is, the clamping member 20 may include other bent portions, as long as the other bent portions are exposed in the thickness direction of the bracket body 10 and can abut against the armature 200.

[0064] In addition, in some embodiments, the bracket body 10 may have a first mounting part 102 in addition to the position of the clearance groove 101, the first mounting part 102 being used for fixed connection with the armature 200.

[0065] Since the bracket body 10 has a first mounting portion 102 at the location excluding the clearance groove 101, when it is necessary to mount the bracket body 10 onto the armature 200, it can be directly connected to the armature 200 through the first mounting portion 102, thereby completing the connection between the bracket body 10 and the armature 200, and avoiding the problem of the bracket body 10 easily shaking relative to the armature 200. That is, by providing the first mounting portion 102, it is easy to fix the bracket body 10 and the armature 200 together.

[0066] In addition, in some embodiments, the first mounting part 102 can be a connecting through hole, and the connecting through hole penetrates the bracket body 10 along the thickness direction of the bracket body 10.

[0067] Since the first mounting part 102 is a connecting through hole, when it is necessary to install the bracket body 10 on the armature 200, the armature 200 can have a connecting boss, so that the connecting through hole can be directly sleeved on the connecting boss to complete the connection and fixation of the bracket body 10 and the armature 200. Furthermore, the connecting through hole and the connecting boss can cooperate to limit the bracket body 10, so as to prevent the bracket body 10 from easily shaking relative to the armature 200, which may cause the bracket body 10 and the armature 200 to separate.

[0068] It should be noted that the number of connecting through holes can be set according to actual needs. For example, the number of connecting through holes may be 1, or the number of connecting through holes may be 2. This application does not limit the specific number of connecting through holes.

[0069] Of course, the first mounting part 102 can also take other forms. For example, the first mounting part 102 can be a boss. In this case, the armature 200 is only provided with a connecting hole. The boss is embedded into the connecting hole to realize the connection between the bracket body 10 and the armature 200. The specific form of the first mounting part 102 is not limited in this embodiment.

[0070] In addition, in some embodiments, side wings 30 are respectively provided on opposite sides of the support body 10 along the first direction X, and the clearance groove 101 is located between the two side wings 30. Both side wings 30 protrude from the support body 10 along the thickness direction of the support body 10, and both side wings 30 protrude from the support body 10 in the same direction. The two side wings 30 are used to cooperate with the armature 200.

[0071] Since both side wings 30 protrude from the support body 10 along its thickness direction and in the same direction, after the support body 10 is mounted on the armature 200, one side wing 30 is located on one side of the armature 200, and the other side wing 30 is located on the other side. Thus, the two side wings 30 cooperate with the armature 200, limiting the support body 10 in the direction from one side wing 30 to the other, preventing the support body 10 from easily wobbling relative to the armature 200 in this direction. In other words, side wings 30 are respectively provided on opposite sides of the support body 10 along the first direction X, so that after the support body 10 is mounted on the armature 200, the two side wings 30 can limit the support body 10 in the first direction X, preventing the support body 10 from easily wobbling.

[0072] It should be noted that the two side wings 30 and the bracket body 10 can be an integral structure. Of course, the two side wings 30 can also be connected to the bracket body 10 by welding. The embodiment of this application does not limit the way the side wings 30 are set on the bracket body 10.

[0073] In addition, in some embodiments, the side wing 30 includes a connecting part 31 and a supporting part 32. The connecting part 31 is connected to the bracket body 10, and the supporting part 32 is connected to the connecting part 31. The supporting part 32 and the connecting part 31 have a first preset angle. The plane where the supporting part 32 is located is parallel to the plane where the bracket body 10 is located. In this case, along the thickness direction of the bracket body 10, both the connecting part 31 and the supporting part 32 protrude from the bracket body 10.

[0074] Since the connecting part 31 is connected to the bracket body 10, and the supporting part 32 is connected to the connecting part 31, and there is a first preset angle between the supporting part 32 and the connecting part 31, and the plane where the supporting part 32 is located is parallel to the plane where the bracket body 10 is located, after the support frame 100 is applied to the vacuum relay, the vacuum relay has an armature 200 and an electromagnetic component 300. The armature 200 is located on the top wall of one end of the electromagnetic component 300. After the support frame 100 is installed on the armature 200, the supporting part 32 can be fixedly connected to the top wall of one end of the electromagnetic component 300, and the clamping member 20 abuts against the armature 200 and squeezes the armature 200, applying force to the armature 200, so that after the electromagnetic component 300 of the vacuum relay is de-energized, the clamping member 20 can ensure that the armature 200 returns to its initial position.

[0075] It should be noted that the plane containing the support portion 32 and the plane containing the connecting portion 31 can have a first preset angle. The first preset angle can be 90 degrees, or it can be 89 degrees or 91 degrees. It is only necessary to ensure that the plane containing the support portion 32 is perpendicular or nearly perpendicular to the plane containing the connecting portion 31.

[0076] Furthermore, in this embodiment, the plane containing the support portion 32 is parallel to the plane containing the bracket body 10, which facilitates the processing of the side wings 30. Of course, the plane containing the support portion 32 and the plane containing the bracket body 10 may not be parallel. This embodiment does not limit the scope of this application.

[0077] In this embodiment, since the support body 10 is provided with a relief groove 101, which extends through the support body 10 along its thickness direction, the relief groove 101 effectively forms an installation space. A deformable clamping member 20 can then be installed within this space. Specifically, a deformable clamping member 20 is installed in the relief groove 101, with a portion of the clamping member 20 exposed in the relief groove 101 along the thickness direction of the support body 10. This allows the support frame 100 to be used in vacuum relay applications. In electrical applications, the bracket body 10 can be mounted on the armature 200 of a vacuum relay. Since the clamping member 20 is exposed outside the relief groove 101, it is deformable, thus abutting against the armature 200 and applying force to it, thereby clamping the armature 200. The deformability of the clamping member 20 prevents excessive rigidity of the tail protrusion of the support frame 100. This deformable characteristic of the clamping member 20 reduces the operating voltage of the vacuum relay, preventing problems such as high operating voltage. Furthermore, the bracket body 10 has a first mounting portion 102, which facilitates the fixed connection between the bracket body 10 and the armature 200, and facilitates the mounting of the bracket body 10 on the armature 200. Furthermore, side wings 30 are respectively provided on opposite sides of the bracket body 10, and the clearance groove 101 is located between the two side wings 30. Both side wings 30 protrude from the bracket body 10 along the thickness direction of the bracket body 10. Thus, when the bracket body 10 is installed on the armature 200, the side wings 30 can cooperate with the armature 200, increasing the cooperation points between the bracket body 10 and the armature 200, facilitating the cooperation between the bracket body 10 and the armature 200, and further limiting the bracket body 10, avoiding the problem of the bracket body 10 being easy to move relative to the armature 200.

[0078] This application provides an armature spring assembly, such as... Figures 3 to 6 As shown, the armature spring assembly includes an armature 200, a connecting frame 400, and a support frame 100 as described in any of the above embodiments; the support body 10 is mounted on the armature 200.

[0079] The armature 200 has a mounting surface 201, the bracket body 10 is mounted on the mounting surface 201, and the clamping member 20 abuts against the mounting surface 201; the connecting frame 400 includes a connecting body 410 and a connecting plate 420, the connecting plate 420 is disposed at one end of the connecting body 410, and the other end of the connecting body 410 is disposed on the mounting surface 201, and the connecting plate 420 is used to cooperate with the transmission rod 003.

[0080] In this embodiment, the bracket body 10 is mounted on the armature 200, and the clamping member 20 abuts against the armature 200, thereby allowing the clamping member 20 to apply force to the armature 200. Specifically, when the armature spring assembly is applied to a vacuum relay, the armature 200 can be made to contact the electromagnetic component 300 of the vacuum relay. When the electromagnetic component 300 is energized, it generates a magnetic force, which attracts the armature 200 and applies force to it, causing the position of the armature 200 to change. The armature 200 also applies force to the clamping member 20, causing the clamping member 20 to deform. When the electromagnetic component 300 is de-energized, the clamping member 20, due to its own deformation, can apply force to the armature 200, causing the armature 200 to return to its initial position.

[0081] Additionally, in some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the armature 200 has a mounting surface 201, the support frame 100 is mounted on the mounting surface 201, and the clamping member 20 abuts against the mounting surface 201; the armature 200 also has a support surface 202 opposite to the mounting surface 201, the support surface 202 includes a first sub-surface 2021 and a second sub-surface 2022, the first sub-surface 2021 and the second sub-surface 2022 are connected, the first sub-surface 2021 and the second sub-surface 2022 have a second preset included angle, and the second sub-surface 2022 is parallel to the mounting surface 201.

[0082] Since the armature 200 has a mounting surface 201, the support bracket 100 can be mounted on the mounting surface 201, and the clamping member 20 abuts against the mounting surface 201. Because the first sub-surface 2021 of the support surface 202 is connected to the second sub-surface 2022, and the first sub-surface 2021 and the second sub-surface 2022 have a second pre-angle, and the second sub-surface 2022 is parallel to the mounting surface 201, when the armature spring assembly is applied in a vacuum relay, the support surface 202 of the armature 200 can contact the top wall of one end of the electromagnetic component 300 of the vacuum relay. When the electromagnetic component 300 is not energized, the first sub-surface 2021 contacts the top wall of one end of the electromagnetic component 300, and the clamping member 20 presses against it. When the electromagnetic component 300 is energized, the armature 200 generates a magnetic force, causing the second sub-face 2022 of the armature 200 to contact the top wall of one end of the electromagnetic component 300. That is, the armature 200 changes position under the magnetic force of the electromagnetic component 300, and the armature 200 exerts a force on the clamping member 20. Thus, once the electromagnetic component 300 is de-energized, the clamping member 20 can exert a force on the armature 200 due to its own elasticity, causing the first sub-face 2021 of the armature 200 to contact the top wall of one end of the electromagnetic component 300. In addition, there is a second preset angle between the first sub-surface 2021 and the second sub-surface 2022, which is equivalent to setting an angle on the support surface of the armature 200. This simplifies the armature processing, and the magnetic gap of the vacuum relay can be guaranteed by this angle, thereby stabilizing the magnetic gap and improving the consistency of the magnetic gap. Furthermore, setting the first sub-surface 2021 and the second sub-surface 2022 also allows the armature 200 to fit better with the magnetic guide cylinder 310 of the electromagnetic component 300, resulting in better magnetic conductivity of the magnetic guide cylinder 310.

[0083] It should be noted that the second preset angle between the first sub-face 2021 and the second sub-face 2022 can be set according to actual needs. For example, the second preset angle between the first sub-face 2021 and the second sub-face 2022 is 10 degrees, or 5 degrees, or 15 degrees. This application does not limit the specific angle in this regard.

[0084] In addition, in this embodiment, the support surface 202 and the mounting surface 201 are opposite to each other in the thickness direction of the armature 200.

[0085] In addition, in some embodiments, the bracket body 10 has a first mounting part 102 and a second mounting part 2011 is provided on the mounting surface 201, and the first mounting part 102 and the second mounting part 2011 cooperate.

[0086] Since the bracket body 10 has a first mounting portion 102 and a second mounting portion 2011 is provided on the mounting surface 201, when it is necessary to mount the bracket body 10 on the mounting surface 201, the first mounting portion 102 and the second mounting portion 2011 can be directly engaged to complete the mounting of the bracket body 10 on the armature 200. That is, by providing the second mounting portion 2011 on the mounting surface 201, it is easy to engage with the first mounting portion 102 of the bracket body 10, thereby facilitating the mounting of the bracket body 10 on the mounting surface 201 of the armature 200.

[0087] It should be noted that the armature 200 also has a side surface. The side surface of the armature 200 is the surface between the mounting surface 201 and the support surface 202 of the armature 200. Therefore, when the side wings 30 are provided on both sides of the bracket body 10, after the bracket body 10 is installed on the mounting surface 201, the two side wings 30 can respectively cooperate with the side surface of the armature 200 with clearance, so that the two side wings 30 can limit the bracket body 10.

[0088] In addition, in some embodiments, the first mounting part 102 is a connecting through hole, and the second mounting part 2011 is a connecting boss, with the connecting boss embedded in the connecting through hole.

[0089] Since the first mounting part 102 is a connecting through hole and the second mounting part 2011 is a connecting boss, when the bracket body 10 is mounted on the mounting surface 201 of the armature 200, the connecting boss can be embedded in the connecting through hole, thereby completing the installation of the bracket body 10 on the mounting surface 201.

[0090] Of course, the second mounting part 2011 can also be of other types. For example, when the first mounting part 102 is a boss, the second mounting part 2011 can be a groove. In this case, when it is necessary to mount the bracket body 10 on the mounting surface 201, the boss on the bracket body 10 can be embedded in the groove on the mounting surface 201, and the boss and the groove can cooperate to limit the bracket body 10. For another example, the second mounting part 2011 includes a first groove and a first boss, both of which are provided on the mounting surface 201. The second mounting part 2011 also includes a second groove and a second boss. When it is necessary to mount the bracket body 10 on the mounting surface 201, the first boss can be embedded in the second groove, and the second boss can be embedded in the second groove, which makes the limiting effect on the bracket body 10 better.

[0091] In addition, in some embodiments, a pressing groove 2012 is provided on the mounting surface 201. Along the thickness direction of the armature 200, the pressing groove 2012 is positioned opposite to the first sub-surface 2021, and the clamping member 20 abuts against the bottom of the pressing groove 2012.

[0092] The pressing groove 2012 is positioned opposite to the first sub-surface 2021, which means that the position of the pressing member 20 applying force to the armature 200 is opposite to the first sub-surface 2021. This ensures that when the electromagnetic component 300 of the vacuum relay is de-energized, the pressing member 20 applies force to the armature 200, ensuring that the first sub-surface 2021 is in contact with the top wall of one end of the electromagnetic component 300.

[0093] Additionally, in the embodiments of this application, such as Figure 4 The pressure groove 2012 may occupy only a portion of the mounting surface 201, and the bottom of the pressure groove 2012 forms a stepped structure with the mounting surface 201. Of course, if... Figure 7 As shown, the pressure groove 2012 may also have multiple groove walls. The specific form of the pressure groove 2012 is not limited in this embodiment.

[0094] In addition, in some embodiments, the plane containing the bottom of the pressure groove 2012 is parallel to the first sub-surface 2021.

[0095] When the armature 200 experiences a positional change due to the magnetic force of the electromagnetic component 300, and after the electromagnetic component 300 is de-energized, the clamping member 20 applies force to the bottom of the pressing groove 2012, causing the first sub-surface 2021 to contact the top wall of one end of the electromagnetic component 300. The plane containing the bottom of the pressing groove 2012 is parallel to the first sub-surface 2021. This ensures that during actual use of the vacuum relay, the clamping point of the clamping member 20 on the armature 200 is consistent each time it presses against it. Therefore, after the electromagnetic component 300 is de-energized, the clamping force on the armature 200 by the clamping member 20 is stable. In other words, by setting the plane containing the bottom of the pressing groove 2012 to be parallel to the first sub-surface 2021, the force applied by the clamping member 20 to the armature 200 each time can be ensured to be relatively stable.

[0096] In some embodiments, a fastener (not shown in the figure) is provided on the mounting surface 201, the connecting body 410 is connected to the fastener, and the fastener supports the connecting body 410.

[0097] When the armature spring assembly provided in this application embodiment is applied to a vacuum relay, the connecting plate 420 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 connecting body 410 to move, thereby the connecting body 410 drives the connecting plate 420 to move, and the connecting plate 420 drives the transmission rod 300 to move, so that the normally open contact of the vacuum relay closes, providing normally open pressure to the normally open contact. Since the connecting body 410 is connected to the fixing member, and the fixing member supports the connecting body 410, the connecting body 410 is not bent. Therefore, during the movement of the armature 10, the armature 10 applies force to the connecting body 410 along the extension direction of the connecting body 410. As a result, the connecting body 410 moves in a direction perpendicular to the mounting surface 101 and applies force to the transmission rod 300. This prevents the extension direction of the connecting body 410 from tilting relative to the mounting surface 101. Thus, when the bracket plate drives the transmission rod 300 to move, the transmission rod 300 is subjected to the component force of the connecting body 410, avoiding the problem of low normally open pressure of the normally open contact.

[0098] In some embodiments, the bracket body 10 has a first mounting portion 102 at the location of the clearance groove 101, and the first mounting portion 102 is fixedly connected to the armature 200. The clamping member 20 is located on the first side of the first mounting portion 102, and the connecting frame 400 is located on the second side of the first mounting portion 102, with the first side and the second side facing away from each other. With this arrangement, it is equivalent to the clamping member 20 being located on the same side of the fixed position of the first mounting portion 102 on the armature 200 and the fixed position of the connecting frame 400 on the armature 200. That is, it is equivalent to the clamping member 20 being located on the same side of the fixed end of the armature 200 that fixes the first mounting portion 102 and the fixed end of the connecting frame 400. This makes the clamping member 20 located on the same side of the two fixed ends of the armature 200. Therefore, compared with the U-shaped bend between the two fixed end segments in the related art, the armature 200 spring assembly in this application can effectively prevent the armature 200 from moving back and forth.

[0099] This application provides a vacuum relay, which includes the support frame 100 in any of the above embodiments.

[0100] In this embodiment, since the bracket body 10 is provided with a clearance groove 101, which penetrates the bracket body 10 along its thickness direction and also penetrates one side wall of the bracket body 10, the clearance groove 101 effectively forms an installation space. A deformable clamping member 20 can then be installed in this installation space. Specifically, a deformable clamping member 20 is installed in the clearance groove 101, and one end of the clamping member 20 is aligned with the clearance groove 101. The groove wall of the support body 10 is connected, and at least part of the clamping member 20 is exposed in the thickness direction of the support body 10 through the relief groove 101. The support body 10 can be installed on the armature 200 in the vacuum relay. Since the clamping member 20 is exposed in the relief groove 101, the clamping member 20 can be deformed, so that the clamping member 20 abuts against the armature 200 and applies force to the armature 200, so that the armature 200 is clamped. The clamping member 20 can be deformed to avoid the tail bulge of the support frame 100 having too large rigidity. That is, in this embodiment of the application, by providing a clearance groove 101 on the bracket body 10, and providing a deformable clamping member 20 in the clearance groove 101, at least part of the clamping member 20 is exposed outside the clearance groove 101 in the thickness direction of the bracket body 10, so that when the bracket body 10 is installed on the armature 200, the clamping member 20 can abut against the armature 200 and apply force to the armature 200, and the clamping member 20 is deformable, so the clamping member 20 can be deformed under force, avoiding the large rigidity of the tail bulge of the support frame 100 which is not easy to deform. The deformable characteristic of the clamping member 20 can reduce the operating voltage of the vacuum relay, avoid the problem of high operating voltage of the vacuum relay, and thus ensure that the operating voltage of the vacuum relay is small, saving energy.

[0101] In addition, the vacuum relay also includes an electromagnetic component and a support frame as described in any of the above embodiments; the electromagnetic component 300 includes a magnetic cylinder 310 and an electromagnetic coil 320, the electromagnetic coil 320 being disposed in the magnetic cylinder 310, and the support frame being disposed on the top wall of one end of the magnetic cylinder 310.

[0102] In addition, along the first direction X, the bracket body 10 is provided with side wings 30 on opposite sides, and the clearance groove 101 is located between the two side wings 30; the two side wings 30 are clearance-fitted with the armature 200, the bracket body 10 has a first mounting part 102 except for the position of the clearance groove 101, and the first mounting part 102 is fixedly connected to the armature 200, the clamping member 20 and the side wings 30 are located on the first side of the first mounting part 102, and the connecting frame 400 is located on the second side of the first mounting part 102, with the first side and the second side facing away from each other. With this arrangement, the clamping member 20 is positioned on the same side as the fixed position of the first mounting part 102 on the armature 200 and the fixed position of the connecting frame 400 on the armature 200. In other words, the clamping member 20 is positioned on the same side of the armature 200 where the first mounting part 102 and the connecting frame 400 are fixed. This arrangement ensures that the clamping member 20 is on the same side of both fixed ends of the armature 200. Compared to the U-shaped bend between the two fixed end segments in related technologies, the armature spring assembly in this application effectively prevents the armature 200 from shifting back and forth. Even if the clamping member 20 deforms, it will not affect the forward and backward movement of the armature 200. Furthermore, the side wing 30 is fixed to the top wall of one end of the magnetic cylinder 310, further integrating the entire assembly and preventing forward and backward movement of the armature 200 and the entire assembly.

[0103] This application provides a vacuum relay, such as... Figure 8 and Figure 9 As shown, the vacuum relay includes the armature reed assembly in any of the above embodiments.

[0104] In this embodiment, since the bracket body 10 is provided with a clearance groove 101, which penetrates the bracket body 10 along its thickness direction and also penetrates one side wall of the bracket body 10, the clearance groove 101 effectively forms an installation space. A deformable clamping member 20 can then be installed in this installation space. Specifically, a deformable clamping member 20 is installed in the clearance groove 101, and one end of the clamping member 20 is aligned with the clearance groove 101. The groove wall of the support body 10 is connected, and at least part of the clamping member 20 is exposed in the thickness direction of the support body 10 through the relief groove 101. The support body 10 can be installed on the armature 200 in the vacuum relay. Since the clamping member 20 is exposed in the relief groove 101, the clamping member 20 can be deformed, so that the clamping member 20 abuts against the armature 200 and applies force to the armature 200, so that the armature 200 is clamped. The clamping member 20 can be deformed to avoid the tail bulge of the support frame 100 having too large rigidity. That is, in this embodiment of the application, by providing a clearance groove 101 on the bracket body 10, and providing a deformable clamping member 20 in the clearance groove 101, at least part of the clamping member 20 is exposed outside the clearance groove 101 in the thickness direction of the bracket body 10, so that when the bracket body 10 is installed on the armature 200, the clamping member 20 can abut against the armature 200 and apply force to the armature 200, and the clamping member 20 is deformable, so the clamping member 20 can be deformed under force, avoiding the large rigidity of the tail bulge of the support frame 100 which is not easy to deform. The deformable characteristic of the clamping member 20 can reduce the operating voltage of the vacuum relay, avoid the problem of high operating voltage of the vacuum relay, and thus ensure that the operating voltage of the vacuum relay is small, saving energy.

[0105] The vacuum relay may also include an electromagnetic component and an armature reed assembly as described in any of the above embodiments. The armature reed assembly includes a connecting frame 400. The electromagnetic component 300 includes a magnetic cylinder 310 and an electromagnetic coil 320. The electromagnetic coil 320 is disposed in the magnetic cylinder 310. The armature 200 is disposed on the top wall of one end of the magnetic cylinder 310. The clamping member 20 is located on one side of the connecting frame 400.

[0106] The vacuum relay may also include a housing, in which normally open contact 001 and normally closed contact 002 are disposed, and transmission rod 003 is disposed in the housing. A connecting bracket 400 may be disposed on the mounting surface 201 of armature 200, and the connecting bracket 400 is mounted on the mounting surface 201 and connected to transmission rod 003. When the electromagnetic coil 320 is energized, it generates magnetism, causing the armature 200 to move. The second sub-face 2022 of the armature 200 abuts against the top wall of one end of the magnetic cylinder 310. At the same time, the transmission rod 003 moves to the normally open contact 001, making the vacuum relay normally open. The position of the armature 200 changes, causing the armature 200 to exert force on the clamping member 20. When the electromagnetic coil 320 is de-energized, the clamping member 20 exerts force on the armature 200, causing the armature 200 to reset. Thus, the first sub-face 2021 of the armature 200 abuts against the top wall of one end of the magnetic cylinder 310. The transmission rod 003 moves to the normally closed contact 002, making the vacuum relay normally closed.

[0107] It should also be noted that the connecting frame 400 includes a connecting body 410 and a connecting plate 420. The connecting body 410 is mounted on the mounting surface 201, and the connecting plate 420 is connected to the transmission rod 003. For example, Figure 7 As shown, the connecting body 410 can be tilted relative to the mounting surface 201. Of course, as... Figure 8 As shown, the plane where the connecting body 410 is located can also be perpendicular to the mounting surface 201. In addition, the connecting plate 420 can be provided with a connecting hole for connecting the transmission rod 003.

[0108] In addition, in this embodiment, the connecting frame 400 can be connected to the support frame 100, which is equivalent to the connecting body 410 being connected to the bracket body 10. Of course, the connecting frame 400 and the support frame 100 can also be distributed at intervals, that is, the connecting frame 400 and the support frame 100 are two independent components. In this respect, this embodiment does not limit the scope of the application.

[0109] In addition, in this embodiment of the application, when the side wings 30 are provided on both sides of the support body 10, and the side wings 30 include a connecting part 31 and a supporting part 32, the supporting part 32 is fixedly connected to the top wall of one end of the magnetic cylinder 310, specifically by welding.

[0110] In addition, in this embodiment of the application, when the armature 200 is placed on the top wall of one end of the magnetic cylinder 310, there is a second preset angle between the first sub-surface 2021 and the second sub-surface 2022 of the armature 200, so that there is a magnetic gap between the armature 200 and the magnetic cylinder 310, and the consistency of the magnetic gap is high.

[0111] It should be noted that the normally open pressure in this embodiment is the pressure that can close the normally open contact 001 and keep the contact closed, and the normally closed pressure in this embodiment is the pressure that can close the normally closed contact 002 and keep the contact closed.
