[0002] This disclosure claims priority to Chinese Patent Application No. 202510336119.4, filed on March 20, 2025, entitled “Relay”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electrical control device technology, and more specifically, to a contact component and a relay. Background Technology

[0004] 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.

[0005] A relay includes a moving spring and a magnetic circuit. The moving spring has a moving contact, and the magnetic circuit is configured to drive the moving spring to deform, thereby causing the moving spring to move the moving contact. In related technologies, to improve the flexibility of the moving spring, its length is usually designed to be relatively long. However, a longer moving spring is not conducive to saving material costs, and it also increases the height of the relay, which is not conducive to product miniaturization design. Summary of the Invention

[0006] According to a first aspect of this application, a contact assembly is provided, including a stationary spring portion and a movable spring portion. The stationary spring portion has a set of stationary contacts; the movable spring portion includes an extension portion, a bent section, a movable section, and a set of movable contacts, one end of the bent section being connected to the extension portion, and the other end of the bent section being integrally connected to the movable section, the set of movable contacts being disposed on the movable section for contacting or separating from the set of stationary contacts; wherein, the movable section is bent in the opposite direction by means of the bent section to a position opposite to the extension portion in a first direction, the first direction being the contact and separation direction of the set of movable contacts and the set of stationary contacts.

[0007] According to a second aspect of this application, a relay is provided, including the contact component described above. Attached Figure Description

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.

[0020] 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.

[0021] As shown in Figures 1 and 2, the relay of this embodiment includes a base 10, a contact assembly 50, and a magnetic circuit portion 40. The contact assembly 50 includes a stationary spring portion 20 and a moving spring portion 30, which are mounted on the base 10. The magnetic circuit portion 40 is configured to drive the moving spring portion 30 to move in response to an input signal, so that the moving spring portion 30 contacts or separates from the stationary spring portion 20.

[0022] Understandably, the relay may also include a top cover (not shown in the figure), which engages with the base 10 to enclose the stationary spring portion 20, the moving spring portion 30, and the magnetic circuit portion 40 within the cavity formed by the top cover and the base 10.

[0023] In one embodiment, the base 10 and the top cover are made of an insulating material, such as plastic, but are not limited thereto.

[0024] As shown in Figures 2 and 3, the stationary spring portion 20 includes a stationary spring lead-out piece 20a and a stationary contact assembly 20b. The stationary spring lead-out piece 20a is connected to the base 10, and a portion of the stationary spring lead-out piece 20a extends out of the lower surface of the base 10. In one embodiment, the stationary spring lead-out piece 20a is inserted into the base 10, but this is not a limitation.

[0025] The stationary contact assembly 20b is connected to the stationary spring lead-out piece 20a. In one embodiment, the stationary contact assembly 20b and the stationary spring lead-out piece 20a are separate structures; in another embodiment, the stationary contact assembly 20b and the stationary spring lead-out piece 20a are an integral structure. When the stationary contact assembly 20b and the stationary spring lead-out piece 20a are separate structures, the stationary contact assembly 20b can be installed on the stationary spring lead-out piece 20a by riveting, welding, or other methods.

[0026] As shown in Figure 4, the movable spring portion 30 includes an outlet portion 30a, a bent section 322, a movable section 323, and a moving contact assembly 33. One end of the bent section 322 is connected to the outlet portion 30a, and the other end of the bent section 322 is integrally connected to the movable section 323. The moving contact assembly 33 is connected to the movable section 323 and is used to contact or separate from the stationary contact assembly 20b. The movable section 323 is bent in the opposite direction by means of the bent section 322 to a position opposite to the outlet portion 30a in the first direction D1.

[0027] The lead-out portion 30a is connected to the base 10, and a portion of the lead-out portion 30a extends out of the lower surface of the base 10.

[0028] In one embodiment, the movable spring portion 30 includes a movable spring lead-out piece 31, a movable spring piece 32, and a movable contact assembly 33. The movable spring lead-out piece 31 is connected to the base 10, and a portion of the movable spring lead-out piece 31 extends beyond the lower surface of the base 10. In one embodiment, the movable spring lead-out piece 31 is inserted into the base 10, but this is not a limitation. The portions of the stationary spring lead-out piece 20a and the movable spring lead-out piece 31 extending beyond the lower surface of the base 10 are used for connection to an external circuit.

[0029] The movable spring 32 is fixedly connected to the movable spring lead-out piece 31, for example, by riveting or welding. The movable contact assembly 33 is connected to the movable spring 32. In one embodiment, the movable contact assembly 33 and the movable spring 32 can be separate structures; in another embodiment, the movable contact assembly 33 and the movable spring 32 can be an integral structure. By designing the movable contact assembly 33 and the movable spring 32 as an integral structure, the number of parts and assembly processes can be reduced, resulting in higher yield and better product consistency. When the movable contact assembly 33 and the movable spring 32 are separate structures, the movable contact assembly 33 can be installed on the movable spring 32 by riveting, welding, or other methods.

[0030] The magnetic circuit section 40 can drive the moving spring 32 to move, so that the moving spring 32 drives the moving contact group 33 to contact or separate from the stationary contact group 20b.

[0031] As shown in Figure 2, the magnetic circuit section 40 includes a coil assembly 41, an armature assembly 42, and a push rod 43. The coil assembly 41 is magnetically coupled to the armature assembly 42. One end of the push rod 43 is connected to the armature assembly 42, and the other end is connected to the movable spring 32. The coil assembly 41 is configured to drive the armature assembly 42 to swing in response to an input signal. In turn, the armature assembly 42 drives the push rod 43 to reciprocate. The push rod 43 drives the movable spring 32 to move, thereby causing the moving contact group 33 to contact or separate from the stationary contact group 20b.

[0032] Of course, in other embodiments, the magnetic circuit portion 40 can also be linearly driven. For example, the coil assembly 41 is configured to drive the armature assembly 42 to move linearly in response to an input signal.

[0033] In addition, the magnetic circuit part 40 may not include the push rod 43, but the armature assembly 42 is directly connected to the moving spring 32, and the movement of the moving spring 32 is directly driven by the movement of the armature assembly 42.

[0034] It is understood that the contact type of the relay in the embodiments of this application can be changeover type, normally open type or normally closed type.

[0035] When the relay contacts are normally open, the moving contact group 33 is separated from the stationary contact group 20b when the coil assembly 41 is not energized; when the relay is normally closed, the moving contact group 33 is in contact with the stationary contact group 20b when the coil assembly 41 is not energized.

[0036] When the relay contacts are of a changeover type, the stationary spring lead-out piece 20a may include a first stationary spring lead-out piece 21 and a second stationary spring lead-out piece 22, both mounted on the base 10. The stationary contact group 20b may include a first stationary contact group 23 and a second stationary contact group 24, the first stationary contact group 23 mounted on the first stationary spring lead-out piece 21 and the second stationary contact group 24 mounted on the second stationary spring lead-out piece 22; the moving contact group 33 is located between the first stationary contact group 23 and the second stationary contact group 24. When a forward current is applied to the coil assembly 41, the moving contact group 33 contacts the first stationary contact group 23 and separates from the second stationary contact group 24; when a reverse current is applied to the coil assembly 41, the moving contact group 33 contacts the second stationary contact group 24 and separates from the first stationary contact group 23.

[0037] The moving contact group 33 may have one or more moving contacts, the first stationary contact group 23 may have one or more stationary contacts, and the second stationary contact group 24 may have one or more stationary contacts. This application does not limit these features.

[0038] The following explanation uses a relay with a changeover contact type as an example. For ease of explanation, as shown in Figure 1, a first direction D1, a second direction D2, and a third direction D3 are defined. The first direction D1 is the contact separation direction between the moving contact group 33 and the stationary contact group 20b; the second direction D2 is the axial direction of the coil assembly 41; and the first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other.

[0039] As shown in Figure 4, the movable spring 32 has a connecting section 321, a bent section 322, and a movable section 323. In this embodiment, the lead-out portion 30a includes the connecting section 321 and the movable spring lead-out piece 31. The connecting section 321 is connected to the movable spring lead-out piece 31. In one embodiment, the connecting section 321 and the movable spring lead-out piece 31 are connected separately, for example, by riveting, welding, or other methods. One end of the bent section 322 is integrally connected to the connecting section 321, and the other end of the bent section 322 is integrally connected to the movable section 323. That is, the connecting section 321, the bent section 322, and the movable section 323 are an integral structure. The movable contact group 33 is mounted on the movable section 323 for contacting or separating from the stationary contact group 20b. The movable section 323 is bent in the opposite direction by means of the bent section 322 to a position opposite to at least one of the movable spring lead-out piece 31 and the connecting section 321 in the first direction D1.

[0040] The relay of this application embodiment includes a moving spring 32 comprising an integrally connected connecting section 321, a bent section 322, and a movable section 323. The movable section 323 is bent in the opposite direction by the bent section 322 to a position opposite to at least one of the moving spring lead-out piece 31 and the connecting section 321 in a first direction D1. This bent section 322 provides sufficient flexibility, allowing the movable section 323 to drive the moving contact group 33 to contact or separate from the stationary contact group 20b. The bent section 322 of the moving spring 32 eliminates the need for an excessively long overall length, ensuring sufficient flexibility and saving material costs. Furthermore, the bending of the movable section 323 to a position opposite to at least one of the moving spring lead-out piece 31 and the connecting section 321 significantly reduces the height occupied by the moving spring 32, facilitating miniaturization of the product design. In addition, the connecting section 321, the bending section 322 and the movable section 323 are integrated into a single structure, which helps to improve assembly efficiency and the structural strength of the moving spring 32.

[0041] In one embodiment, the movable segment 323 and the spring extension piece 31 are arranged opposite to each other in the first direction D1, while the movable segment 323 and the connecting segment 321 are arranged offset in the first direction D1. The orthographic projections of the movable segment 323 and the spring extension piece 31 on a target plane have overlapping areas, while the orthographic projections of the movable segment 323 and the connecting segment 321 on the target plane do not have overlapping areas; the target plane is perpendicular to the first direction D1.

[0042] In another embodiment, the movable segment 323 and the connecting segment 321 are arranged opposite to each other in the first direction D1, while the movable segment 323 and the spring extension piece 31 are arranged offset in the first direction D1. The orthographic projections of the movable segment 323 and the connecting segment 321 on the target plane have overlapping areas, while the orthographic projections of the movable segment 323 and the spring extension piece 31 on the target plane do not have overlapping areas.

[0043] In another embodiment, the movable segment 323 and the spring extension piece 31 are arranged opposite to each other in the first direction D1, and the movable segment 323 and the connecting segment 321 are also arranged opposite to each other in the first direction D1. The orthographic projections of the movable segment 323 and the spring extension piece 31 on the target plane have overlapping areas, and the orthographic projections of the movable segment 323 and the connecting segment 321 on the target plane also have overlapping areas.

[0044] As shown in Figure 4, the bending path of the curved segment 322 is an arc, and the central angle of this arc is θ, where 180°≤θ≤240°. For example, θ can be 180°, 190°, 200°, 210°, 220°, 230°, 240°, etc. The bending path of the movable spring 32 can be, but is not limited to, U-shaped, M-shaped, V-shaped, etc.

[0045] Of course, in other embodiments, the bending path of the bending segment 322 can also be a non-circular curve, as long as the movable segment 323 bends in the opposite direction via the bending segment 322 to a position opposite to at least one of the moving spring lead-out piece 31 and the connecting segment 321 in the first direction D1. Within the limited space of the relay, the detour path of the bending segment can achieve a long lever arm and low stress for the moving spring piece 32, which is beneficial for the miniaturization, long life and low power consumption of the relay.

[0046] In one embodiment, when the coil assembly 41 is not energized, the movable section 323 is parallel to the connecting section 321.

[0047] As shown in Figures 3 and 5, the curved section 322 has at least one opening 325; the opening 325 starts from the connecting section 321 and extends along the bending direction of the curved section 322 toward the movable section 323, and the size of the opening 325 gradually increases.

[0048] In this embodiment, by providing an opening 325 on the bent section 322, and designing the size of the opening 325 to gradually increase in the direction extending from the connecting section 321 to the movable section 323, the overall stiffness of the bent section 322 forms a gradient change. On the one hand, the end of the bent section 322 near the connecting section 321 has greater stiffness, ensuring the static stability of the moving spring when the coil is not energized, and preventing the moving spring from shaking and malfunctioning. On the other hand, the end of the bent section 322 near the movable section 323 has better flexibility, ensuring the flexibility and response speed of the movable section 323. Furthermore, the gradually changing size of the opening 325 optimizes the stress distribution, avoids stress concentration inside the bent section 322, significantly extends the fatigue life of the bent section 322, and reduces the mass of the moving end of the bent section 322, reducing inertia, which is beneficial to improving the contact breaking speed and reducing chatter, thus comprehensively improving the reliability and dynamic performance of the relay.

[0049] In one embodiment, the curved section 322 has a plurality of openings 325 arranged side by side along a third direction D3. For example, the number of openings 325 may be two, but is not limited thereto.

[0050] As shown in Figures 6 and 7, the movable reed 32 also has a drive segment 324 connected to the movable segment 323. The drive segment 324 is configured to be driven by an external force to move the movable segment 323. In one example, a push rod 43 is connected to the drive segment 324 and is used to drive the movable segment 323 to move via the drive segment 324, so that the movable segment 323 drives the moving contact assembly 33 to move.

[0051] In one embodiment, the drive segment 324 is connected to the end of the movable segment 323 away from the curved segment 322. The drive segment 324 and the movable segment 323 are an integral structure.

[0052] Of course, in other embodiments, the drive segment 324 may also be connected to one side of the movable segment 323 along the third direction D3.

[0053] As shown in Figures 6 and 7, the drive section 324 includes a first section 3241 and a second section 3242. One end of the first section 3241 is connected to the end of the movable section 323 away from the curved section 322. One end of the second section 3242 is connected to the other end of the first section 3241, and the second section 3242 extends out of the side surface of the first section 3241 away from the magnetic circuit portion 40 (i.e., the second section 3242 extends from the first section 3241 toward the direction close to the lead-out portion 30a).

[0054] As shown in Figures 8 and 9, one end of the push rod 43 is connected to the armature assembly 42, and the other end of the push rod 43 is connected to the first segment 3241, while the second segment 3242 supports the other end of the push rod 43.

[0055] In this embodiment of the application, the second segment 3242 extends from the side surface of the first segment 3241 facing away from the magnetic circuit portion 40, and the second segment 3242 supports the other end of the push rod 43, which can prevent the push rod 43 from detaching from the moving spring 32 during the reciprocating pushing and pulling of the first segment 3241.

[0056] As shown in Figures 7 and 9, the first segment 3241 includes a bending part 3241a and a force-receiving part 3241b. One end of the bending part 3241a is connected to the movable segment 323, and one end of the force-receiving part 3241b is connected to the other end of the bending part 3241a. The other end of the force-receiving part 3241b is connected to the second segment 3242. The other end of the push rod 43 has a slot 431, and the force-receiving part 3241b is inserted into the slot 431.

[0057] In the embodiments of this application, the force-receiving part 3241b is inserted into the slot 431 of the push rod 43, which can further prevent the push rod 43 from disengaging from the moving spring 32.

[0058] As shown in Figure 7, the movable spring 32 is composed of two conductive sheets 32a stacked together. The two conductive sheets 32a are made of different materials, and the stiffness of one conductive sheet 32a is greater than that of the other conductive sheet 32a.

[0059] In this embodiment, the movable spring 32 is composed of two conductive sheets 32a, which reduces the number of parts, simplifies assembly, and lowers costs. Furthermore, compared to stacked conductive sheets 32a (three or more), the movable spring 32 of this application, composed of two conductive sheets 32a, is more flexible and easier to deform.

[0060] In one embodiment, one conductive sheet 32a is made of pure copper, and the other conductive sheet 32a is made of alloy copper. Pure copper improves the conductivity of the moving spring sheet 32, while alloy copper provides better rigidity.

[0061] As a modified embodiment, the lead-out portion 30a may include a connecting section 321 but not the movable spring lead-out piece 31. The connecting section 321, the bent section 322, and the movable section 323 are integrally connected to form the movable spring piece 32. The connecting section 321 is connected to the base 10, and a portion of the connecting section 321 extends out of the lower surface of the base 10.

[0062] In summary, the relays of the embodiments of this application have at least the following advantages and beneficial effects:

[0063] The relay of this application embodiment includes a moving spring 32 comprising an integrally connected connecting section 321, a bent section 322, and a movable section 323. The movable section 323 is bent in the opposite direction by the bent section 322 to a position opposite to at least one of the moving spring lead-out piece 31 and the connecting section 321 in a first direction D1. This bent section 322 provides sufficient flexibility, allowing the movable section 323 to drive the moving contact group 33 to contact or separate from the stationary contact group 20b. The bent section 322 of the moving spring 32 eliminates the need for an excessively long overall length, ensuring sufficient flexibility and saving material costs. Furthermore, by bending the movable section 323 to a position opposite to at least one of the moving spring lead-out piece 31 and the connecting section 321 within the limited space of the relay, a long lever arm and low stress can be achieved in the moving spring 32, significantly reducing the height occupied by the moving spring 32. This facilitates miniaturization while maintaining the relay's long lifespan and low power consumption. In addition, the connecting section 321, the bending section 322 and the movable section 323 are connected as a whole to form a single component, which helps to improve assembly efficiency.

[0064] Furthermore, by providing an opening 325 on the bent section 322, and designing the size of the opening 325 to gradually increase in the direction extending from the connecting section 321 towards the movable section 323, the overall stiffness of the bent section 322 forms a gradient change. On the one hand, the end of the bent section 322 near the connecting section 321 has greater stiffness, ensuring the static stability of the moving spring when the coil is not energized, preventing the moving spring from shaking and malfunctioning. On the other hand, the end of the bent section 322 near the movable section 323 has better flexibility, ensuring the flexibility and response speed of the movable section 323. Moreover, the gradually changing size of the opening 325 optimizes stress distribution, avoids stress concentration inside the bent section 322, significantly extends the fatigue life of the bent section 322, and reduces the mass of the moving end of the bent section 322, reducing inertia, which is beneficial for improving contact breaking speed and reducing chatter, thus comprehensively improving the reliability and dynamic performance of the relay.

[0065] Furthermore, the second segment 3242 extends from the side surface of the first segment 3241 facing away from the magnetic circuit portion 40, and the second segment 3242 supports the other end of the push rod 43, thus preventing the push rod 43 from detaching from the moving spring 32 during the reciprocating pushing and pulling of the first segment 3241.

[0066] Furthermore, the force-receiving part 3241b is engaged in the slot 431 of the push rod 43, which can further prevent the push rod 43 from disengaging from the moving spring 32.
