Description

Technical Field

[0001] This application relates to the field of electrical control device technology, and more specifically, to a push rod component and a relay. Background Technology

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is commonly used in automatic control circuits. Essentially, a relay is 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] A high-voltage DC relay is a type of relay that includes a stationary contact assembly, a moving assembly, and a magnetic circuit. The moving assembly includes a moving contact assembly and a push rod member, with the moving contact assembly mounted on the push rod member. The magnetic circuit is configured to drive the push rod member in response to an input signal, causing the moving contact assembly to contact or separate from the stationary contact assembly.

[0004] However, in existing high-voltage DC relays, the push rod component is prone to rotate around its own axis, which in turn causes the moving contact assembly to deflect, resulting in inconsistent contact positions of the moving and stationary contacts, unstable contact resistance, and affecting the reliability of the relay.

[0037] According to some embodiments of this application, the support segment includes a first segment and a second segment, the second segment being perpendicularly connected to the first segment, the connecting segment being located between the two first segments, and the elastic arm simultaneously abutting against the two second segments.

[0038] According to some embodiments of this application, the connecting segment and the first segment are flat plates, and the connecting segment and the first segment are arranged in the same plane.

[0039] The relay in this application embodiment includes the push rod component described in any of the above claims.

[0040] According to some embodiments of this application, the relay further includes a wall portion; the elastic arm of the elastic member contacts the wall portion, or there is a gap between the elastic arm of the elastic member and the wall portion.

[0041] According to some embodiments of this application, the wall portion is made of ceramic material and includes a substrate and a rib, the rib protruding from the inner surface of the substrate, and the elastic member is capable of contacting the rib.

[0042] According to some embodiments of this application, the relay further includes a first moving contact, and both ends of the first moving contact in the length direction are provided with elastic arms.

[0043] According to some embodiments of this application, the relay further includes a first static contact assembly, a second static contact assembly, a first moving assembly, and a second moving assembly, wherein the first moving assembly includes the push rod member;

[0044] When the relay is in the first state, the first moving component is in contact with the first stationary contact component, while the second moving component is separated from the second stationary contact component; when the relay is in the second state, the second moving component is in contact with both the first stationary contact component and the second stationary contact component, while the first moving component is separated from the first stationary contact component.

[0045] An embodiment of the above application has at least the following advantages or beneficial effects:

[0046] In the push rod component and relay of this application embodiment, during the movement of the push rod component, the elastic arm can contact the wall, and the wall can provide a reaction force to the elastic arm. This reaction force can suppress the rotation of the push rod component around its own axis, thereby ensuring the consistency of the contact position and the stability of the contact resistance, and improving the reliability of the relay operation.

[0047] Furthermore, the contact between the elastic arm and the rib reduces the contact area between the elastic arm and the wall. On the one hand, this reduces the resistance of the wall to the elastic arm, ensuring the smooth movement of the first push rod component. On the other hand, it avoids the generation of scraping due to the large contact area between the elastic arm and the wall.

[0048] Furthermore, by providing a first bend on the elastic arm and configuring it as a stress point for external forces acting on the elastic component, the first bend can generate a certain rebound force when subjected to external forces, thereby absorbing the reaction force applied to the elastic arm by the wall, ensuring that the first push rod component reliably reciprocates along the second direction, and is not prone to rotating around its own axis. In addition, when the first push rod component is installed into the ceramic cover, the first bend of the elastic arm is interference-fitted with the rib, and the first bend has a certain rebound force, which ensures that the first push rod component can be smoothly installed into the ceramic cover.

[0049] Furthermore, the first bend and the second bend are connected. The second bend can abut against the outer surface of the raised portion, allowing it to provide support to the first bend. This ensures that the first bend maintains a stable shape after contacting the wall, preventing rotation of the first push rod component due to significant deformation of the first bend, and guaranteeing consistency in the contact position of the moving and stationary contacts and stability of the contact resistance. Simultaneously, the second bend also prevents the first bend from twisting under stress, thereby reducing the risk of deformation and cracking of the elastic arm.

[0050] Furthermore, there is an included angle α between the extension and the raised portion, that is, the extension is arranged at an angle relative to the raised portion. When the first bent portion deforms due to pressure, the extension will not come into contact with the raised portion due to the inclined arrangement of the extension, thereby ensuring that the second bent portion slides smoothly relative to the raised portion.

[0051] Furthermore, a third bend is provided between the first bend and the raised portion. The third bend can reduce the stress on the elastic arm and reduce the risk of the elastic arm breaking due to deformation.

[0052] Furthermore, the elastic arm abuts against the support section, which provides more reliable support to the elastic arm, resulting in a more stable support force.

[0053] Furthermore, the two support arms can support the elastic arm, and the connecting section is located between the two support arms. The mounting part of this embodiment can not only provide good support for the elastic arm, but also reduce its own weight. Attached Figure Description

[0070] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0071] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0072] like Figures 1 to 3 As shown, the relay of this embodiment includes a housing 10, a contact cavity 20, a stationary contact assembly 30, a moving assembly 40, and a magnetic circuit portion 60. The contact cavity 20, the stationary contact assembly 30, the moving assembly 40, and the magnetic circuit portion 60 are disposed within the housing 10. The stationary contact assembly 30 is mounted on the contact cavity 20, and a portion of the moving assembly 40 is located within the contact chamber 23 enclosed by the contact cavity 20 and is movable relative to the contact cavity 20. The magnetic circuit portion 60 is configured to drive the moving assembly 40 to move in response to an input signal, so that the moving assembly 40 contacts or separates from the stationary contact assembly 30, thereby switching the relay between a first state and a second state.

[0073] The term "contact" refers to direct or indirect contact between the moving component 40 and the stationary contact component 30, allowing current to flow between them; the term "separation" refers to the disconnection between the moving component 40 and the stationary contact component 30, preventing current from flowing between them.

[0074] In one embodiment, in the first state and the second state, one is an external circuit controlled by a relay in parallel, and the other is an external circuit controlled by a relay in series.

[0075] Of course, in other embodiments, one of the first state and the second state can be a closed state and the other is an open state.

[0076] The following explanation will be based on the example where the external circuit controlled by the relay is in series in the first state and in parallel in the second state.

[0077] As an example, the outer casing 10 may include a first casing 11 and a second casing 12, which are connected to form a cavity for accommodating the contact cavity 20, the static contact assembly 30, the moving assembly 40, and the magnetic circuit portion 60. The shape of the first casing 11 and the second casing 12 connected together can be a cuboid, a cylinder, etc. In the embodiments of this application, the first casing 11 and the second casing 12 are connected to form a hollow cuboid, but this is not a limitation.

[0078] In one embodiment, both the first shell 11 and the second shell 12 are cuboid in shape and each has an opening on one side. The opening of the first shell 11 is opposite to the opening of the second shell 12, and the first shell 11 and the second shell 12 are fastened together to form a cavity for accommodating the cavity.

[0079] Of course, in other embodiments, the first shell 11 can be a flat plate structure, and the second shell 12 can be a cuboid shape with an opening, forming a cavity after the first shell 11 and the second shell 12 are fastened together.

[0080] like Figure 3 As shown, the contact cavity 20 includes an insulating cover 21 and a yoke plate 22. The insulating cover 21 covers one side surface of the yoke plate 22 in the thickness direction, and the insulating cover 21 and the yoke plate 22 form a contact cavity 23. The magnetic circuit portion 60 is located on the side of the yoke plate 22 facing away from the insulating cover 21.

[0081] In one embodiment, the insulating cover 21 may include a ceramic cover 211 and a frame plate 212. The ceramic cover 211 is made of ceramic material and is connected to the yoke plate 22 via the frame plate 212. The frame plate 212 may be a ring-shaped metal component, for example, made of an iron-nickel alloy. One end of the frame plate 212 is connected to the opening edge of the ceramic cover 211, for example, by laser welding, brazing, resistance welding, or adhesive bonding. The other end of the frame plate 212 is connected to the yoke plate 22, for example, by laser welding, brazing, resistance welding, or adhesive bonding.

[0082] like Figure 2 As shown, the static contact assembly 30 includes a first static contact assembly 31 and a second static contact assembly 32, both of which are mounted on the ceramic cover 211.

[0083] In one embodiment, the first static contact assembly 31 has two first static contacts 311, and the second static contact assembly 32 has two second static contacts 321. Both the first static contacts 311 and the second static contacts 321 are mounted on a ceramic cover 211. The two first static contacts 311 are arranged at a distance along a first direction D1, and the two second static contacts 321 are also arranged at a distance along the first direction D1. The positions of the two first static contacts 311 correspond to the positions of the two second static contacts 321 along a third direction D3.

[0084] Among them, the direction of motion of the moving component 40 is the second direction D2, and the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0085] like Figure 3 As shown, the moving component 40 includes a first moving component 40a and a second moving component 40b. The first moving component 40a is used to contact or separate from the first stationary contact component 31, and the second moving component 40b is used to contact or separate from the first stationary contact component 31 and the second stationary contact component 32 simultaneously.

[0086] When the external circuit controlled by the relay is in series, the first moving component 40a is in contact with the first stationary contact component 31, while the second moving component 40b is separated from the second stationary contact component 32. When the external circuit controlled by the relay is in parallel, the second moving component 40b is in contact with both the first stationary contact component 31 and the second stationary contact component 32, while the first moving component 40a is separated from the first stationary contact component 31.

[0087] like Figure 2 As shown, the first moving assembly 40a includes a first push rod member 416 and a first moving contact assembly 415. The first moving contact assembly 415 is mounted on the first push rod member 416 and is used to contact or separate from the first stationary contact assembly 31. The second moving assembly 40b includes a second push rod member 426 and two second moving contact assemblies 425. The second moving contact assemblies 425 are mounted on the second push rod member 426 and are used to simultaneously contact or separate from the first contact assembly 31 and the second stationary contact assembly 32.

[0088] In one implementation, such as Figure 2 As shown, the first movable contact assembly 415 has one or more first movable contact elements 4151. When the first movable contact assembly 415 has multiple first movable contact elements 4151, the multiple first movable contact elements 4151 are arranged side by side along a third direction D3. Each second movable contact assembly 425 has one or more second movable contact elements 4251. When the second movable contact assembly 425 has multiple second movable contact elements 4251, the multiple second movable contact elements 4251 are arranged side by side along a first direction D1.

[0089] In the embodiments of this application, when the external circuit controlled by the relay is in a series connection, both ends of the first moving contact component 415 are simultaneously in contact with the two first stationary contacts 311, and the second moving contact component 425 is separated from the second stationary contact 321. When the external circuit controlled by the relay is in a parallel connection, both ends of each second moving contact component 425 are in contact with the corresponding first stationary contact 311 and second stationary contact 321, and the first moving contact component 415 is separated from the first stationary contact 311.

[0090] like Figure 3 As shown, the magnetic circuit portion 60 is located on the side of the yoke plate 22 facing away from the insulating cover 21.

[0091] In this embodiment of the application, the magnetic circuit portion 60 includes two magnetic drive components, one of which is connected to the first push rod member 416 and configured to drive the first push rod member 416 to move in response to a first input signal, and the other magnetic drive component is connected to the second push rod member 426 and configured to drive the second push rod member 426 to move in response to a second input signal.

[0092] The magnetic drive component can be a magnetic holding structure or a non-magnetic holding structure.

[0093] like Figure 4 As shown, the first push rod component 416 includes a push rod 411, a mounting base 412, and an elastic member 417. The mounting base 412 is connected to one axial end of the push rod 411, and a first moving contact assembly 415 is mounted on the mounting base 412. The elastic member 417 is connected to the mounting base 412 and has at least one elastic arm 418, at least a portion of which extends out of the periphery of the mounting base 412.

[0094] In one embodiment, the mounting base 412 and the elastic member 417 are separate structures.

[0095] like Figure 5 and Figure 6 As shown, the ceramic cover 211 has a wall portion 213 located to the side of the first moving contact assembly 415. The elastic arm 418 is capable of contacting the wall portion 213 to reduce the amplitude of rotation of the first push rod member 416 about its own axis or to prevent rotation of the first push rod member 416 about its own axis. As an example, the elastic arm 418 is interference-fitted with the wall portion 213.

[0096] In one embodiment, when the magnetic circuit drive assembly connected to the first push rod member 416 is not energized, the elastic arm 418 is in contact with the wall portion 213. Thus, when the magnetic circuit drive assembly is energized, it can drive the first push rod member 416 to move, and during the movement of the first push rod member 416, the elastic arm 418 remains in contact with the wall portion 213. When the first push rod member 416 tends to rotate about its own axis, the wall portion 213 provides a reaction force to the elastic arm 418. This reaction force suppresses the rotation of the first push rod member 416 about its own axis, thereby ensuring the consistency of the contact position and the stability of the contact resistance, and improving the reliability of the relay operation.

[0097] In another embodiment, when the magnetic circuit drive assembly connected to the first push rod member 416 is not energized, there is a gap between the elastic arm 418 of the elastic member 417 and the wall portion 213. Thus, when the magnetic circuit drive assembly is energized, it can drive the first push rod member 416 to move. When the first push rod member 416 tends to rotate about its own axis, since the elastic arm 418 and the wall portion 213 have a gap and are not in direct contact, the first push rod member 416 can generate a small amount of rotation about its own axis. When the first push rod member 416 continues to rotate until the elastic arm 418 contacts the wall portion 213, the wall portion 213 can provide a reaction force to the elastic arm 418, which can inhibit the first push rod member 416 from continuing to rotate about its own axis. Therefore, the elastic member 417 and the wall portion 213 can reduce the amplitude of the first push rod member 416's rotation about its own axis, ensuring, to a certain extent, the consistency of the contact position.

[0098] Continue reading Figure 5 and Figure 6 The wall portion 213 includes a base 213a and a rib 213b. The rib 213b protrudes from the inner surface of the base 213a, and the elastic arm 418 can contact the rib 213b.

[0099] In this embodiment of the application, the elastic arm 418 contacts the rib 213b, which reduces the contact area between the elastic arm 418 and the wall 213. On the one hand, this can reduce the resistance of the wall 213 to the elastic arm 418 and ensure the smooth movement of the first push rod component 416. On the other hand, it can avoid the generation of scraping due to the large contact area between the elastic arm 418 and the wall 213.

[0100] In one embodiment, the rib 213b is elongated and extends along the second direction D2.

[0101] Furthermore, this application does not limit the number of ribs 213b that contact the elastic arm 418. For example, the elastic arm 418 may contact one rib 213b, or it may contact multiple ribs 213b simultaneously. In the embodiment of this application, the base 213a is provided with two ribs 213b, and the elastic arm 418 contacts both ribs 213b simultaneously.

[0102] like Figure 7 As shown, the elastic component 417 also includes a fixing part 419 fixed to the mounting base 412, and at least one elastic arm 418 is connected to both ends of the fixing part 419 along the first direction D1.

[0103] In the embodiments of this application, each end of the fixing part 419 along the first direction D1 is connected to an elastic arm 418, but this is not a limitation. For example, each end of the fixing part 419 along the first direction D1 may also be connected to multiple elastic arms 418.

[0104] In one embodiment, the fixing part 419 includes a first fixing part 419a and a second fixing part 419b respectively fixed to the mounting base 412, and at least one elastic arm 418 includes a first elastic arm 418a and a second elastic arm 418b. The first elastic arm 418a is connected to the first fixing part 419a, and the second elastic arm 418b is connected to the second fixing part 419b.

[0105] In other words, in this embodiment of the application, the elastic member 417 has two separately configured elastic members, which can be symmetrically arranged in the first direction D1. One elastic member includes a first fixing part 419a and a first elastic arm 418a, and the other elastic member includes a second fixing part 419b and a second elastic arm 418b.

[0106] In one embodiment, the first elastic arm 418a is integrally formed with the first fixing part 419a; and / or, the second elastic arm 418b is integrally formed with the second fixing part 419b.

[0107] Of course, in other embodiments, the elastic member 417 may also be an integral part, which includes a fixing part 419 and a first elastic arm 418a and a second elastic arm 418b respectively connected to the two ends of the fixing part 419 along the first direction D1.

[0108] In one embodiment, elastic arms 418 are arranged at both ends of the first moving contact 4151 along its length.

[0109] In one embodiment, the elastic member 417 is formed by bending a metal sheet, so that the elastic arm 418 has good resilience.

[0110] Of course, the material of the elastic component 417 is not limited to metal. For example, it can also be a synthetic resin with a relatively high heat resistance, such as polybutylene terephthalate or polycarbonate.

[0111] In one embodiment, the elastic member 417 is formed by bending an elongated sheet structure, and the elastic member 417 has grooves 417a on both sides in the width direction. The elastic arm 418 has a slot 4187.

[0112] The fixing part may be provided with a groove 417a, and the elastic arm 418 may also be provided with a groove 417a.

[0113] In the embodiments of this application, the groove 417a and slot 4187 provided on the elastic member 417 can reduce the stress at the connection between the elastic member 417 and the mounting base 412 and prevent the elastic member 417 from cracking.

[0114] Please continue reading. Figure 7 The mounting base 412 may include a base 412a and a mounting member 412b. The base 412a, the mounting member 412b and the push rod 411 are connected, and the fixing part 419 is connected to the mounting member 412b.

[0115] In one embodiment, the base 412a can be made of plastic material, and the mounting part 412b can be made of metal material. The base 412a can be integrally connected to the push rod 411 and the mounting part 412b by injection molding process.

[0116] When the elastic member 417 is formed by bending a metal sheet, since both the elastic member 417 and the mounting part 412b are metal parts, the firmness of the connection between the fixing part 419 of the elastic member 417 and the mounting part 412b can be guaranteed, thus preventing the elastic member 417 from shaking relative to the mounting part 412b.

[0117] As an example, the elastic component 417 and the mounting component 412b can be connected by riveting, welding or other methods.

[0118] In other embodiments, when the elastic member 417 is a single piece, the mounting base 412 may not include the mounting member 412b. Instead, the base 412a, the push rod 411, and the fixing part 419 of the elastic member 417 are integrally connected, for example, through injection molding.

[0119] Please continue reading. Figure 7 The mounting component 412b includes at least one mounting portion 4121 extending from the periphery of the base 412a, and the fixing portion 419 is connected to the mounting portion 4121.

[0120] In one embodiment, both the mounting part 4121 and the fixing part 419 are flat plates, and the fixing part 419 is stacked with the mounting part 4121, which improves the connection reliability.

[0121] In this embodiment of the application, the mounting member 412b has two mounting portions 4121, which extend from the two side surfaces of the base 412a along the first direction D1. The first fixing portion 419a is fixedly connected to one of the mounting portions 4121, and the second fixing portion 419b is fixedly connected to the other mounting portion 4121.

[0122] It should be noted that, in one embodiment, the mounting member 412b can be a single integral part, and the portion of the integral part extending out of the two side surfaces of the base 412a constitutes two mounting portions 4121. In another embodiment, the mounting member 412b may also include two separate parts, and the portion of each separate part extending out of the base 412a constitutes a mounting portion 4121.

[0123] like Figure 8 and Figure 9 As shown in the embodiments of this application, the first elastic arm 418a and the first fixed part 419a, the second elastic arm 418b and the second fixed part 419b have the same structure. The following description will only take the structure of the first elastic arm 418a and the first fixed part 419a as an example. The structure of the second elastic arm 418b and the second fixed part 419b will not be described again.

[0124] The first elastic arm 418a has a raised portion 4185, a first bent portion 4181, a second bent portion 4182, a third bent portion 4183, and a fourth bent portion 4184. One end of the raised portion 4185 is connected to the first fixed portion 419a, the other end of the raised portion 4185 is connected to one end of the fourth bent portion 4184, the other end of the fourth bent portion 4184 is connected to one end of the third bent portion 4183, the other end of the third bent portion 4183 is connected to one end of the first bent portion 4181, and the other end of the first bent portion 4181 is connected to one end of the second bent portion 4182. The first elastic arm 418a also has an extension portion 4186, which is connected to the other end of the second bent portion 4182.

[0125] like Figure 9 As shown, in one embodiment, the raised portion 4185 extends from the first fixing portion 419a toward the axis away from the push rod 411 and toward the top of the ceramic cover 211.

[0126] In one embodiment, the first bend 4181 is configured as a point of contact for external forces acting on the elastic member 417. In this embodiment, the first bend 4181 is capable of contacting the rib 213b.

[0127] In this embodiment, by providing a first bending portion 4181 on the elastic arm 418, the first bending portion 4181 can generate a certain rebound force when subjected to external force, thereby absorbing the reaction force applied to the elastic arm 418 by the wall portion 213, ensuring that the first push rod member 416 reliably reciprocates along the second direction D2, and is not prone to rotating around its own axis. In addition, when the first push rod member 416 is installed into the ceramic cover 211, the first bending portion 4181 of the elastic arm 418 contacts the protruding rib 213b, and the first bending portion 4181 has a certain rebound force, which can ensure that the first push rod member 416 can be smoothly installed into the ceramic cover 211.

[0128] like Figure 8 As shown, both the first bend 4181 and the second bend 4182 are located outside the raised portion 4185. Here, "outer side" refers to the side of the raised portion 4185 facing away from the first moving contact assembly 415. When the first bend 4181 is subjected to an external force, the second bend 4182 can abut against the outer surface of the raised portion 4185 to provide support to the first bend 4181.

[0129] In this embodiment of the application, the first bend 4181 is connected to the second bend 4182. The second bend 4182 can abut against the outer surface of the raised portion 4185, so that the second bend 4182 can provide support force to the first bend 4181, so as to ensure that the first bend 4181 has a stable shape after contacting the wall portion 213, and avoid the first push rod member 416 from rotating due to large deformation of the first bend 4181, thus ensuring the consistency of the contact position of the moving and stationary contacts and the stability of the contact resistance.

[0130] like Figure 8 As shown, there is an included angle α between the extension 4186 and the raised portion 4185, where 10°≤α≤40°. For example, α is 10°, 15°, 20°, 25°, 30°, 35°, or 40°.

[0131] In the embodiments of this application, there is an included angle α between the extension 4186 and the raised portion 4185, that is, the extension 4186 is arranged at an inclination relative to the raised portion 4185. When the first bent portion 4181 deforms due to pressure, since the extension 4186 is arranged at an inclination relative to the raised portion 4185, the extension 4186 will not contact the raised portion 4185, thereby ensuring that the second bent portion 4182 slides smoothly relative to the raised portion 4185.

[0132] In one embodiment, the first bend 4181 protrudes away from the raised portion 4185, and the second bend 4182 protrudes towards the raised portion 4185. The first bend 4181 protrudes away from the raised portion 4185, and the third bend 4183 protrudes towards the raised portion 4185.

[0133] In this embodiment of the application, a third bend 4183 is provided between the first bend 4181 and the raised portion 4185. The third bend 4183 can reduce the stress on the elastic arm and reduce the risk of the elastic arm 418 breaking due to deformation.

[0134] In one embodiment, the radius of curvature of the first bend 4181 is smaller than the radius of curvature of the third bend 4183.

[0135] In one embodiment, the first bend 4181 is arc-shaped, the second bend 4182 is arc-shaped, the third bend 4183 is arc-shaped, and the fourth bend 4184 is arc-shaped.

[0136] like Figures 10 to 12 As shown, the similarities between the first moving component of the second embodiment and the first moving component of the first embodiment will not be repeated here, but the differences are as follows:

[0137] like Figure 12 As shown, the elastic arm 418 includes a first bending portion 4181, a second bending portion 4182 and a third bending portion 4183. One end of the third bending portion 4183 is connected to the fixing portion 419, the other end of the third bending portion 4183 is connected to one end of the first bending portion 4181, and the other end of the first bending portion 4181 is connected to one end of the second bending portion 4182.

[0138] like Figure 11 As shown, the mounting portion 4121 has an extension section 4124, a connecting section 4122, and a support section 4123. One end of the support section 4123 is connected to the extension section 4124, and the other end of the support section 4123 is connected to the connecting section 4122. The fixing portion 419 is connected to the connecting section 4122, and the second bent portion 4182 of the elastic arm 418 abuts against the outer surface of the support section 4123.

[0139] In the embodiments of this application, the elastic arm 418 abuts against the support section 4123, and the support section 4123 can provide more reliable support to the elastic arm 418, resulting in more stable support force.

[0140] In one embodiment, the fixing part 419 is fixed to the side of the connecting section 4122 opposite to the protruding section 4124. The fixing part 419 has a flange 4191, which is located on the side of the connecting section 4122 opposite to the supporting section 4123 and extends toward the protruding section 4124.

[0141] In this embodiment of the application, the flange 4191 is located on the side of the connecting section 4122 facing away from the support section 4123, which can prevent the elastic component 417 from detaching from the mounting part 4121.

[0142] like Figures 13 to 15 As shown, the similarities between the first moving component of the third embodiment and the first moving component of the first embodiment will not be repeated here, but the differences are as follows:

[0143] The mounting section 4121 has a connecting section 4122 and a supporting section 4123. The supporting section 4123 includes two spaced-apart supporting arms 4125. The connecting section 4122 is located between the two supporting arms 4125. The fixing part is connected to the connecting section 4122. The second bending part 4182 of the elastic arm 418 simultaneously abuts against the two supporting arms 4125.

[0144] In this embodiment of the application, two support arms 4125 can support the elastic arm 418, and the connecting section 4122 is located between the two support arms 4125. The mounting part 4121 in this embodiment of the application can not only provide good support for the elastic arm 418, but also reduce its own weight.

[0145] like Figure 14 As shown, the support segment 4123 includes a first segment 4125a and a second segment 4125b. The second segment 4125b is perpendicularly connected to the first segment 4125a, forming an L-shape. The connecting segment 4122 is located between the two first segments 4125a, and the second bent portion 4182 of the elastic arm 418 simultaneously abuts against both second segments 4125b. The connecting segment 4122 and the first segment 4125a are flat, and the connecting segment 4122 is coplanar with the first segment 4125a.

[0146] In summary, the advantages and beneficial effects of the push rod component and relay of the embodiments of this application are as follows:

[0147] In the push rod component and relay of this application embodiment, during the movement of the push rod component, the elastic arm can contact the wall portion 213, and the wall portion 213 can provide a reaction force to the elastic arm. This reaction force can suppress the push rod component from rotating around its own axis, thereby ensuring the consistency of the contact position and the stability of the contact resistance, and improving the reliability of the relay operation.

[0148] Furthermore, the contact between the elastic arm and the rib 213b reduces the contact area between the elastic arm and the wall 213. On the one hand, this reduces the resistance of the wall 213 to the elastic arm, ensuring the smooth movement of the first push rod component 416. On the other hand, it avoids the generation of scraping due to the large contact area between the elastic arm and the wall 213.

[0149] Furthermore, by providing a first bending portion 4181 on the elastic arm and configuring it as a force-bearing point for external forces acting on the elastic component, the first bending portion 4181 can generate a certain rebound force when subjected to external forces, thereby absorbing the reaction force applied to the elastic arm by the wall portion 213, ensuring that the first push rod member 416 reliably reciprocates along the second direction D2, and is not prone to rotating around its own axis. In addition, when the first push rod member 416 is installed into the ceramic cover 211, the first bending portion 4181 of the elastic arm is interference-fitted with the protruding rib 213b, and the first bending portion 4181 has a certain rebound force, which can ensure that the first push rod member 416 can be smoothly installed into the ceramic cover 211.

[0150] Furthermore, the first bend 4181 is connected to the second bend 4182. The second bend 4182 can abut against the outer surface of the raised portion 4185, allowing the second bend 4182 to provide support to the first bend 4181. This ensures that the first bend 4181 maintains a stable shape after contacting the wall portion 213, preventing the first push rod member 416 from rotating due to large deformation of the first bend 4181, thus ensuring the consistency of the contact position of the moving and stationary contacts and the stability of the contact resistance. Simultaneously, the second bend 4182 can also prevent the first bend 4181 from twisting under force, thereby reducing the risk of deformation and cracking of the elastic arm.

[0151] Furthermore, there is an included angle α between the extension 4186 and the raised portion 4185, that is, the extension 4186 is arranged at an angle relative to the raised portion 4185. When the first bent portion 4181 deforms due to pressure, the extension 4186 will not come into contact with the raised portion 4185 due to the inclined arrangement of the extension 4186, thereby ensuring that the second bent portion 4182 slides smoothly relative to the raised portion 4185.

[0152] Furthermore, a third bend 4183 is provided between the first bend 4181 and the raised portion 4185. The third bend 4183 can reduce the stress on the elastic arm and reduce the risk of the elastic arm breaking due to deformation.

[0153] Furthermore, the elastic arm abuts against the support section 4123, which provides more reliable support to the elastic arm and makes the support force more stable.

[0154] Furthermore, the two support arms 4125 can support the elastic arm, and the connecting section 4122 is located between the two support arms 4125. The mounting part 4121 of this embodiment can not only provide good support for the elastic arm, but also reduce its own weight.
