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

[0050] An avoidance groove 101 is provided on the bracket body 10, and the avoidance groove 101 penetrates the bracket body 10 along the thickness direction of the bracket body 10, and the bracket body 10 is used to be installed on the armature 200; a deformable clamping piece 20 is provided in the avoidance groove 101, and at least part of the clamping piece 20 is exposed from the avoidance groove 101 in the thickness direction of the bracket body 10, and the clamping piece 20 is used to squeeze the armature 200.

[0051] In the embodiment of the present application, since an avoidance groove 101 is provided on the bracket body 10, and the avoidance groove 101 penetrates the bracket body 10 along the thickness direction of the bracket body 10, the avoidance groove 101 is equivalent to forming an installation space, so that a deformable clamping member 20 can be provided in the installation space, that is, a deformable clamping member 20 is provided in the avoidance groove 101, and at least part of the clamping member 20 is exposed in the thickness direction of the bracket body 10 in the avoidance groove 101, so that when the support frame 100 is applied to the vacuum relay, the bracket body 10 can be installed on the armature 200 in the vacuum relay, and the clamping member 20 is exposed in the avoidance groove 101, and 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 compressed, and the clamping member 20 can be deformed to avoid the large rigidity of the rear bulge of the support frame 100. That is, in the embodiment of the present application, an avoidance groove 101 is provided on the bracket body 10, and a deformable clamping piece 20 is provided in the avoidance groove 101, at least a portion of the clamping piece 20 is exposed from the avoidance 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 piece 20 can abut the armature 200 and apply force to the armature 200, and the clamping piece 20 can be deformed, so that the clamping piece 20 can be deformed under force, thereby avoiding the rear convex bump of the support frame 100 being rigid and difficult to deform, so that once the support frame 100 is applied to the vacuum relay, the deformable characteristic of the clamping piece 20 can reduce the operating voltage of the vacuum relay, thereby avoiding the problem of high operating voltage of the vacuum relay.

[0052] In the related art, the support frame 100 includes a support body 10, a U-shaped bending structure is provided in the middle of the support body 10, a connecting convex bulge is provided at the tail of the support body 10, the U-shaped bending structure is connected to the connecting convex bulge, the connecting convex bulge is used to abut against the armature 200, and a mounting hole is provided on the support body 10, and the support body 10 is installed on the armature 200 through the mounting hole. During the process of powering on and off of the electromagnetic assembly 300 in the vacuum relay, the connecting convex bulge needs to abut against the armature 200 and apply force to the armature 200, but the connecting convex bulge has high rigidity and is not easy to deform, resulting in a large pressure applied by the connecting convex bulge to the armature, and then a large pressure of the normally closed contact, resulting in a large voltage of the electromagnetic assembly 300 to provide a larger action voltage. In the embodiment of the present application, the avoidance groove 101 is provided on the bracket body 10, and a deformable pressing member 20 is provided in the avoidance groove 101, at least part of the pressing member 20 is exposed in the avoidance groove 101 in the thickness direction of the bracket body 10, which is equivalent to the rear of the bracket body 10 being provided with a deformable pressing member 20, and the U-shaped bending structure and the connecting convex bump in the related art are cancelled, so that when the bracket body 10 is installed on the armature 200, the pressing member 20 can abut the armature 200 and push the armature to the armature. 200 force is applied, and the clamping member 20 is deformable, so that the clamping member 20 is deformable under force, and the deformable clamping member 20 can reduce rigid interference, and can control the pressure applied to the armature 200 as required, that is, control the pressure of the normally closed contact, avoid the connection convex bump of the support frame 100 being rigid and difficult 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, avoiding the problem of high operating voltage of the vacuum relay. That is, setting a deformable clamping member 20 not only meets the product requirements for normally closed contacts, but also reduces the operating voltage.

[0053] It should be noted that, in the embodiment of the present application, the material of the pressing member 20 can be metal, and it is sufficient to ensure that the pressing member 20 can be deformed. For example, the material of the pressing member 20 is copper.

[0054] In addition, in the embodiment of the present application, the pressing member 20 may be connected to the groove wall of the avoidance groove 102. Of course, the pressing member 20 may also be disconnected from the groove wall of the avoidance groove 102. This embodiment of the present application does not limit this.

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

[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 is opposite to the bending direction of the second bending portion 22, the first bending portion 21 and the second bending portion 22 are 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 opposite to each other, the first bending portion 21 protrudes from the first surface 11, the second bending portion 22 protrudes from the second surface 12, and the second bending portion 22 is used to squeeze the armature 200.

[0057] Since the bending direction of the first bending portion 21 is opposite to the bending direction of the second bending portion 22, the first bending portion 21 and the second bending portion 22 are alternately arranged and connected to each other, so the first bending portion 21 and the second bending portion 22 can be deformed due to the bending effect. 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, so that when the bracket body 10 is installed on the armature 200, the part of the second bending portion 22 exposed in the avoidance groove 101 can be in contact with the armature 200, and the second bending portion 22 can apply force to the armature 200. That is, by providing the first bending portion 21 and the second bending portion 22, the deformation of the clamping member 20 can be facilitated, and it is ensured that the clamping member 20 applies force to the armature 200. In addition, the existence of at least one first bending portion 21 and at least one second bending portion 22 is equivalent to allowing multiple bending portions to jointly bear the deformation, avoiding a single deformation point from being subjected to force, thereby reducing the stress of each bending portion and reducing the risk of plastic deformation of each bending portion.

[0058] It should be noted that the number of the first bending portions 21 and the number of the second bending portions 22 can be set according to actual needs. For example, when the number of the first bending portions 21 and the number of the second bending portions 22 are both 1, the first bending portion 21 and the second bending portion 22 are equivalent to forming an S-shaped structure; for another example, when the number of the first bending portions 21 is 2 and the number of the second bending portions 22 is 2, the first bending portion 21 and the second bending portion 22 are equivalent to forming a wavy structure. The embodiment of the present application does not limit the number of the first bending portions 21 and the number of the second bending portions 22. In order to facilitate processing and avoid the large size of the support frame 100, the number of the first bending portions 21 and the number of the second bending portions 22 can be set to 1.

[0059] In addition, in the embodiment of the present application, one end of a first bent portion 21 can be connected to the groove wall of the avoidance groove 101, which can ensure that the pressing member 20 is connected to the groove wall of the avoidance groove 101, so that the pressing member 20 is connected to the groove wall of the avoidance groove 101, and the problem that the pressing member 20 may be separated from the avoidance groove 101 when the pressing member 20 abuts against the armature 200 may occur. Of course, the first bent portion 21 may not be connected to the groove wall of the avoidance groove 101. In this regard, the embodiment of the present application is not limited here.

[0060] In addition, in some embodiments, the pressing member 20 and the bracket body 10 are an integrated structure. Through such a configuration, the strength of the pressing member 20 and the bracket body 10 of the armature 200 can be improved, thereby ensuring that the pressing member 20 is not easily separated from the bracket body 10, and ensuring that the pressing member 20 can have a good squeezing effect on the armature 200. Among them, the pressing member 20 and the bracket body 10 can be directly cast into an integrated structure through a die-casting process or a casting process.

[0061] It should be noted that when the clamping member 20 includes a first bending portion 21 and a second bending portion 22, a first bending portion 21 is connected to the groove wall of the avoidance groove 101. At this time, the first bending portion 21, the second bending portion 22 and the bracket body 10 can be an integrated structure, that is, the first bending portion 21, the second bending portion 22 and the bracket body 10 are cast into an integrated structure through a die-casting process or a casting process.

[0062] Of course, in the embodiment of the present application, the clamping member 20 can also be connected to the groove wall of the avoidance groove 101 by other means, for example, the clamping member 20 is connected to the groove wall of the avoidance groove 101 by welding. The embodiment of the present application does not limit the way in which the clamping member 20 is connected to the groove wall of the avoidance groove 101. Of course, the clamping member 20 may not be connected to the groove wall of the avoidance groove 101, that is, the first bending portion 101 is not connected to the groove wall of the avoidance groove 101. In this case, the clamping member 20 can be arranged in a split body. In this regard, the embodiment of the present application does not limit it.

[0063] In addition, in the embodiment of the present application, the clamping member 20 may not be limited to including the first bending portion 21 and the second bending portion 22, that is, the clamping member 20 may include other bending portions, as long as the other bending portions are exposed in the avoidance groove 101 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 portion 102 except for the avoidance groove 101 , and the first mounting portion 102 is used for fixed connection with the armature 200 .

[0065] Since the bracket body 10 has the first mounting portion 102 except the position of the avoidance groove 101, when the bracket body 10 needs to be mounted on 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 that the bracket body 10 is easy to shake relative to the armature 200. That is, by providing the first mounting portion 102, the bracket body 10 and the armature 200 can be easily fixedly connected.

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

[0067] Since the first mounting portion 102 is a connecting through hole, when the bracket body 10 needs to be installed 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 between the bracket body 10 and the armature 200, and the connecting through hole and the connecting boss can cooperate to limit the bracket body 10 to prevent the bracket body 10 from shaking relative to the armature 200, which may cause the bracket body 10 to separate from the armature 200.

[0068] It should be noted that the number of the connecting through holes can be set according to actual needs, for example, the number of the connecting through holes is 1, and for another example, the number of the connecting through holes is 2. This is not limited in the embodiments of the present application.

[0069] Of course, the first mounting portion 102 can also be in other forms, for example, the first mounting portion 102 is a boss, in which case only a connecting hole is provided on the armature 200, and the boss is embedded in the connecting hole to achieve the connection between the bracket body 10 and the armature 200. The specific form of the first mounting portion 102 is not limited in the embodiment of the present application.

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

[0071] Since both side wings 30 protrude from the bracket body 10 along the thickness direction of the bracket body 10, and the two side wings 30 protrude from the bracket body 10 along the same direction, after the bracket body 10 is installed 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 of the armature 200, so that the two side wings 30 will cooperate with the armature 200, so that in the direction from one side wing 30 to the other side wing 30, the two side wings 30 limit the bracket body 10, and avoid the problem that the bracket body 10 is easy to shake relative to the armature 200 in the direction from one side wing 30 to the other side wing 30. That is, along the first direction X, the side wings 30 are respectively arranged on the opposite sides of the bracket body 10, so that after the bracket body 10 is installed on the armature 200, the two side wings 30 can limit the bracket body 10 in the first direction X, and avoid the bracket body 10 from shaking easily.

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

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

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

[0075] It should be noted that there may be a first preset angle between the plane where the support portion 32 is located and the plane where the connection portion 31 is located, and the first preset angle may be 90 degrees. Of course, the first preset angle may also be 89 degrees, and the first preset angle may also be 91 degrees. It is only necessary to ensure that the plane where the support portion 32 is located is perpendicular or nearly perpendicular to the plane where the connection portion 31 is located.

[0076] In addition, in the embodiment of the present application, the plane where the support portion 32 is located is parallel to the plane where the bracket body 10 is located, which can facilitate the processing of the side wing 30. Of course, the plane where the support portion 32 is located may not be parallel to the plane where the bracket body 10 is located. This embodiment of the present application is not limited here.

[0077] In the embodiment of the present application, since the bracket body 10 is provided with an avoidance groove 101, and the avoidance groove 101 penetrates the bracket body 10 along the thickness direction of the bracket body 10, the avoidance groove 101 is equivalent to forming an installation space, so that a deformable pressing member 20 can be arranged in the installation space, that is, a deformable pressing member 20 is arranged in the avoidance groove 101, and a part of the pressing member 20 is exposed in the avoidance groove 101 in the thickness direction of the bracket body 10, so that when the support frame 100 is applied to the vacuum relay When the support body 10 is installed in an electrical appliance, the support body 10 can be installed on the armature 200 in the vacuum relay, and the pressing member 20 is exposed in the avoidance groove 101, and the pressing member 20 can be deformed, so that the pressing member 20 abuts against the armature 200 and applies force to the armature 200, so that the armature 200 is compressed, and the pressing member 20 can be deformed to avoid the rear convex bump of the support frame 100 being too rigid, and then the deformable characteristic of the pressing member 20 can reduce the operating voltage of the vacuum relay, and avoid the problem of high operating voltage of the vacuum relay. In addition, a first mounting portion 102 is provided on the support body 10, which can facilitate the fixed connection between the support body 10 and the armature 200, and then facilitate the installation of the support body 10 on the armature 200. In addition, side wings 30 are respectively provided on the opposite sides of the bracket body 10, and the avoidance groove 101 is located between the two side wings 30. The two side wings 30 protrude from the bracket body 10 along the thickness direction of the bracket body 10. Therefore, when the bracket body 10 is installed on the armature 200, the side wings 30 can cooperate with the armature 200 to increase the matching points between the bracket body 10 and the armature 200, which is convenient for the bracket body 10 to cooperate with the armature 200, and the bracket body 10 can be further limited to avoid the problem of easy movement of the bracket body 10 relative to the armature 200.

[0078] The present application embodiment provides an armature reed 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 in any of the above embodiments; the support body 10 is installed on the armature 200 .

[0079] The armature 200 has a mounting surface 201, the bracket body 10 is installed 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 arranged at one end of the connecting body 410, and the other end of the connecting body 410 is arranged on the mounting surface 201, and the connecting plate 420 is used to cooperate with the transmission rod 003.

[0080] In the embodiment of the present application, the bracket body 10 is mounted on the armature 200, and the pressing member 20 is in contact with the armature 200, so that the pressing member 20 can apply force to the armature 200. Specifically, when the armature reed assembly is applied to the vacuum relay, the armature 200 can be in contact with the electromagnetic assembly 300 of the vacuum relay. When the electromagnetic assembly 300 is powered on, the electromagnetic assembly 300 generates magnetic force, and the electromagnetic assembly 300 can attract the armature 200, apply force to the armature 200, so that the position of the armature 200 changes, and the armature 200 applies force to the pressing member 20, so that the pressing member 20 is deformed. When the electromagnetic assembly 300 is powered off, the pressing member 20 can apply force to the armature 200 due to its own deformation, so that the armature 200 returns to its initial position.

[0081] In addition, in some embodiments, 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 is connected to the second sub-surface 2022, there is a second preset angle between the first sub-surface 2021 and the second sub-surface 2022, 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 frame 100 can be mounted on the mounting surface 201, and the pressing piece 20 abuts against the mounting surface 201. Since the first sub-surface 2021 of the supporting surface 202 is connected to the second sub-surface 2022, there is a second pre-angle between the first sub-surface 2021 and the second sub-surface 2022, and the second sub-surface 2022 is parallel to the mounting surface 201, when the armature reed assembly is applied to the vacuum relay, the support surface 202 of the armature 200 can contact the top wall of one end of the electromagnetic assembly 300 of the vacuum relay. When the electromagnetic assembly 300 is not powered on, the first sub-surface 2021 contacts the top wall of one end of the electromagnetic assembly 300, and the pressing piece 20 squeezes the electromagnetic assembly 300. The armature 200, when the electromagnetic assembly 300 is powered on, the electromagnetic assembly 300 generates a magnetic force, so that the second sub-surface 2022 of the armature 200 contacts the top wall of one end of the electromagnetic assembly 300, that is, the armature 200 is equivalent to changing position under the action of the magnetic force of the electromagnetic assembly 300, and the armature 200 will apply force to the clamping piece 20, so that once the electromagnetic assembly 300 is powered off, the clamping piece 20 can apply force to the armature 200 due to its own elasticity, so that the first sub-surface 2021 of the armature 200 contacts the top wall of one end of the electromagnetic assembly 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 oblique angle on the support surface of the armature 200, so that the armature can be simply processed, and the magnetic gap of the magnetic circuit of the vacuum relay can be guaranteed by the oblique angle, so that the magnetic gap of the vacuum relay is stable and the consistency of the magnetic gap is improved. In addition, setting the first sub-surface 2021 and the second sub-surface 2022 can also make the armature 200 and the magnetic tube 310 of the electromagnetic assembly 300 fit better together, so that the magnetic conductivity of the magnetic tube 310 is better.

[0083] It should be noted that the second preset angle between the first sub-surface 2021 and the second sub-surface 2022 can be set according to actual needs. For example, the second preset angle between the first sub-surface 2021 and the second sub-surface 2022 is 10 degrees. For another example, the second preset angle between the first sub-surface 2021 and the second sub-surface 2022 is 5 degrees. For another example, the second preset angle between the first sub-surface 2021 and the second sub-surface 2022 is 15 degrees. This is not limited in the embodiments of the present application.

[0084] In addition, in the embodiment of the present application, 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 portion 102 , and a second mounting portion 2011 is disposed on the mounting surface 201 , and the first mounting portion 102 cooperates with the second mounting portion 2011 .

[0086] Since the bracket body 10 has the first mounting portion 102 and the mounting surface 201 is provided with the second mounting portion 2011, when the bracket body 10 needs to be mounted on the mounting surface 201, the first mounting portion 102 can be directly matched with the second mounting portion 2011 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 convenient to match with the first mounting portion 102 of the bracket body 10, so as to facilitate 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, and 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 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 be respectively matched with the side gaps of the armature 200, so that the two side wings 30 can limit the bracket body 10.

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

[0089] Since the first mounting portion 102 is a connecting through hole and the second mounting portion 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 portion 2011 can also be other types. For example, when the first mounting portion 102 is a boss, the second mounting portion 2011 can be a groove. At this time, when the bracket body 10 needs to be mounted 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 cooperates with the groove to limit the bracket body 10. For another example, the second mounting portion 2011 includes a first groove and a first boss, both of which are arranged on the mounting surface 201, and the second mounting portion 2011 includes a second groove and a second boss. When the bracket body 10 needs to be mounted 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, so that the limiting effect of the bracket body 10 is better.

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

[0092] The pressing groove 2012 is opposite to the first sub-surface 2021, so that the position where the clamping piece 20 applies force to the armature 200 is opposite to the first sub-surface 2021, so that when the electromagnetic assembly 300 of the vacuum relay is powered off, the clamping piece 20 applies force to the armature 200 to ensure that the first sub-surface 2021 contacts the top wall of one end of the electromagnetic assembly 300.

[0093] In addition, in the embodiments of the present application, Figure 4 The pressing groove 2012 may only occupy a portion of the mounting surface 201, and the bottom of the pressing groove 2012 and the mounting surface 201 form a step structure. Figure 7 As shown, the pressing groove 2012 may also have a plurality of groove walls. The specific form of the pressing groove 2012 is not limited in the embodiment of the present application.

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

[0095] When the armature 200 is subjected to the magnetic force of the electromagnetic assembly 300 and the position changes, and after the electromagnetic assembly 300 is powered off, the pressing member 20 applies force to the bottom of the pressing groove 2012, so that the first sub-surface 2021 contacts the top wall of one end of the electromagnetic assembly 300, and the plane where the bottom of the pressing groove 2012 is located is parallel to the first sub-surface 2021, thereby ensuring that in the actual use of the vacuum relay, when the pressing member 20 squeezes the armature 200, the pressing point of the pressing member 20 pressing the armature 200 is consistent each time, so that after the electromagnetic assembly 300 is powered off, the armature 200 is subjected to a stable squeezing force of the pressing member 20. That is, by setting the plane where the bottom of the pressing groove 2012 is located to be parallel to the first sub-surface 2021, it can be ensured that the force applied by the pressing member 20 to the armature 200 each time by the pressing member 20 is relatively stable.

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

[0097] When the armature reed assembly provided in the embodiment of the present application 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, so that when the electromagnetic component 100 is energized, the electromagnetic component 100 generates magnetism to rotate the armature 10, and the armature 10 can drive the connecting body 410 to move, so that 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 contacts of the vacuum relay are closed, providing normally open pressure for the normally open contacts. Since the connecting body 410 is connected to the fixing part, and the fixing part 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, so that the connecting body 410 moves in a direction perpendicular to the mounting surface 101 and applies force to the transmission rod 300, thereby preventing the extension direction of the connecting body 410 from tilting relative to the mounting surface 101. Therefore, 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, thereby avoiding the problem of the normally open pressure of the normally open contact being too small.

[0098] In addition, in some embodiments, the bracket body 10 has a first mounting portion 102 except for the position of the avoidance 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, and the first side is opposite to the second side. Through such a setting, 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 fixing the first mounting portion 102 and the fixed end of the connecting frame 400, so that the clamping member 20 is located on the same side of the two fixed ends of the armature 200, so that compared with the U-shaped bend set between the two fixed end sections in the related art, the armature 200 spring assembly in the present application can effectively prevent the armature 200 from moving back and forth.

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

[0100] In the embodiment of the present application, since the bracket body 10 is provided with an avoidance groove 101, the avoidance groove 101 penetrates the bracket body 10 along the thickness direction of the bracket body 10, and the avoidance groove 101 penetrates a side wall of the bracket body 10, therefore, the avoidance groove 101 is equivalent to forming an installation space, so that a deformable pressing member 20 can be arranged in the installation space, that is, a deformable pressing member 20 is arranged in the avoidance groove 101, and one end of the pressing member 20 is aligned with the avoidance groove 10. 1, and at least part of the pressing piece 20 is exposed in the avoidance groove 101 in the thickness direction of the bracket body 10, the bracket body 10 can be installed on the armature 200 in the vacuum relay, and the pressing piece 20 is exposed in the avoidance groove 101, and the pressing piece 20 can be deformed, so that the pressing piece 20 abuts against the armature 200 and applies force to the armature 200, so that the armature 200 is compressed, and the pressing piece 20 can be deformed, so as to avoid the rear convex bump of the support frame 100 to be large in rigidity. That is, in the embodiment of the present application, an avoidance groove 101 is provided on the bracket body 10, and a deformable clamping piece 20 is provided in the avoidance groove 101, at least a portion of the clamping piece 20 is exposed in the thickness direction of the bracket body 10 from the avoidance groove 101, so that when the bracket body 10 is installed on the armature 200, the clamping piece 20 can abut the armature 200 and apply force to the armature 200, and the clamping piece 20 can be deformed, so that the clamping piece 20 can be deformed under force, thereby avoiding the rear bulge of the support frame 100 being rigid and difficult to deform. The deformable characteristic of the clamping piece 20 can reduce the operating voltage of the vacuum relay, avoid the problem of high operating voltage of the vacuum relay, and further ensure that the operating voltage of the vacuum relay is small, thereby saving electric energy.

[0101] In addition, the vacuum relay also includes an electromagnetic assembly and a support frame in any of the above embodiments; the electromagnetic assembly 300 includes a magnetic tube 310 and an electromagnetic coil 320, the electromagnetic coil 320 is arranged in the magnetic tube 310, and the support frame is arranged on the top wall of one end of the magnetic tube 310.

[0102] In addition, along the first direction X, side wings 30 are respectively arranged on the opposite sides of the bracket body 10, and the avoidance groove 101 is located between the two side wings 30; the two side wings 30 are clearance-matched with the armature 200, and the bracket body 10 has a first mounting portion 102 except for the position of the avoidance groove 101, and the first mounting portion 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 portion 102, and the connecting frame 400 is located on the second side of the first mounting portion 102, and the first side is opposite to the second side. Through such a setting, it is equivalent to that the clamping member 20 is 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 that the clamping member 20 is 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, so that the clamping member 20 is located on the same side of the two fixed ends of the armature 200, so compared with the U-shaped bend set between the two fixed end sections in the related art, the armature spring assembly in the present application can effectively prevent the armature 200 from moving forward and backward, that is, even if the clamping member 20 is deformed, it will not affect the armature 200 from moving forward and backward. And the side wing 30 is fixed to the top wall of one end of the magnetic tube 310, so that the whole assembly can be further integrated through the side wing 30, avoiding the armature 200 from moving forward and backward, and avoiding the whole assembly from moving forward and backward.

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

[0104] In the embodiment of the present application, since the bracket body 10 is provided with an avoidance groove 101, the avoidance groove 101 penetrates the bracket body 10 along the thickness direction of the bracket body 10, and the avoidance groove 101 penetrates a side wall of the bracket body 10, therefore, the avoidance groove 101 is equivalent to forming an installation space, so that a deformable pressing member 20 can be arranged in the installation space, that is, a deformable pressing member 20 is arranged in the avoidance groove 101, and one end of the pressing member 20 is aligned with the avoidance groove 10. 1, and at least part of the pressing piece 20 is exposed in the avoidance groove 101 in the thickness direction of the bracket body 10, the bracket body 10 can be installed on the armature 200 in the vacuum relay, and the pressing piece 20 is exposed in the avoidance groove 101, and the pressing piece 20 can be deformed, so that the pressing piece 20 abuts against the armature 200 and applies force to the armature 200, so that the armature 200 is compressed, and the pressing piece 20 can be deformed, so as to avoid the rear convex bump of the support frame 100 to be large in rigidity. That is, in the embodiment of the present application, an avoidance groove 101 is provided on the bracket body 10, and a deformable clamping piece 20 is provided in the avoidance groove 101, at least a portion of the clamping piece 20 is exposed in the thickness direction of the bracket body 10 from the avoidance groove 101, so that when the bracket body 10 is installed on the armature 200, the clamping piece 20 can abut the armature 200 and apply force to the armature 200, and the clamping piece 20 can be deformed, so that the clamping piece 20 can be deformed under force, thereby avoiding the rear bulge of the support frame 100 being rigid and difficult to deform. The deformable characteristic of the clamping piece 20 can reduce the operating voltage of the vacuum relay, avoid the problem of high operating voltage of the vacuum relay, and further ensure that the operating voltage of the vacuum relay is small, thereby saving electric energy.

A connecting frame 400 may be disposed on the mounting surface 201 of the armature 200, the connecting frame 400 is mounted on the mounting surface 201, and the connecting frame 400 is connected to the transmission rod 003. When the electromagnetic coil 320 is energized, the electromagnetic coil 320 generates magnetism, which causes the armature 200 to move, and the second sub-surface 2022 of the armature 200 abuts against the top wall of one end of the magnetic tube 310. At the same time, the transmission rod 003 moves to the normally open contact 001, so that the vacuum relay is normally open, and the position of the armature 200 changes, so that the armature 200 applies force to the clamping piece 20. When the electromagnetic coil 320 is de-energized, the clamping piece 20 applies force to the armature 200, so that the armature 200 resets, so that the first sub-surface 2021 of the armature 200 abuts against the top wall of one end of the magnetic tube 310, and the transmission rod 003 moves to the normally closed contact 002, so that the vacuum relay is normally closed.

[0108] In addition, in the embodiment of the present application, the connecting frame 400 can be connected to the supporting frame 100, which is equivalent to connecting the connecting body 410 to the bracket body 10. Of course, the connecting frame 400 and the supporting frame 100 can also be spaced apart, that is, the connecting frame 400 and the supporting frame 100 are two independent components. This embodiment of the present application is not limited here.
