Description

Technical Field

[0001] This application relates to the field of electrical control device technology, and more specifically, to 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] In related technologies, a relay includes a ceramic housing, a lead-out component, a moving contact assembly, and a push rod component. The lead-out component is mounted on the ceramic housing, and the moving contact assembly is mounted on the push rod component. The push rod component can drive the moving contact assembly to move so that it contacts and then separates from the lead-out component. To enable the relay to switch between different contact types, related technologies typically connect a roughly C-shaped conductive component below the lead-out component. This conductive component has a conductive portion for contacting the moving contact assembly. However, because the conductive portion is located on the side of the moving contact assembly opposite to the lead-out component, interference occurs when the push rod component and the moving contact assembly are installed inside the ceramic housing, resulting in installation inconvenience.

[0038] According to some embodiments of this application, assembling the dome, the static contact assembly, and the dynamic contact assembly to form a first pre-assembled component includes:

[0039] Assemble the top cover and the static contact assembly to form the first sub-pre-assembly;

[0053] Assemble the first pre-assembled component and the second pre-assembled component in a direction perpendicular to the yoke.

[0054] An embodiment of the above application has at least the following advantages or beneficial effects:

[0055] The relay of this embodiment includes a contact cavity comprising a separately connected top cover, a cover wall, and a yoke. When assembling the contact cavity, the stationary contact assembly, and the moving contact assembly, the stationary contact assembly is first connected to the top cover. Then, the moving contact assembly is inserted from the side of the stationary contact assembly between the stationary component and the conductive part. Finally, the cover wall and the yoke are connected to the top cover, so that the top cover, cover wall, and yoke surround the moving contact assembly. The relay of this embodiment designs the contact cavity as a separate top cover, cover wall, and yoke, which allows the moving contact assembly to be inserted from the side of the stationary contact assembly between the stationary component and the conductive part. This avoids the interference problem that occurs when the moving contact assembly is inserted along its direction of movement between the stationary component and the conductive part. Furthermore, the volume of the contact cavity does not need to be excessively large, which is beneficial for product miniaturization.

[0056] Furthermore, the first connecting part is connected to the side surface of one of the first leads facing the yoke, and the second connecting part is connected to the side surface of one of the second leads facing the yoke, so that the first conductive element is connected to the bottom surface of the first lead rather than the side surface, and the second conductive element is connected to the bottom surface of the second lead rather than the side surface. This can reduce the space occupied by the conductive element on the side of the moving contact assembly to a certain extent, which is beneficial to the miniaturization design of the product.

[0057] Furthermore, the first segment is connected to the surface of the first lead-out member facing the yoke, and this surface is flush with the surface of the other first lead-out member facing the yoke, ensuring that the first conductive element does not excessively occupy volume in the direction of motion (second direction) of the moving assembly. Similarly, the third segment is connected to the surface of one of the second leads-out members facing the yoke, and this surface is flush with the surface of the other second lead-out member facing the yoke, ensuring that the second conductive element does not excessively occupy volume in the direction of motion (second direction) of the moving assembly. Therefore, the static contact assembly of this embodiment includes more compact leads and conductive elements after assembly, improving space utilization.

[0058] Furthermore, the surface of the first segment facing the yoke is flush with the surface of the other first lead-out facing the yoke, and the surface of the third segment facing the yoke is flush with the surface of the other second lead-out facing the yoke, which improves the consistency and reliability of the contact between the two ends of the first moving contact assembly and the two ends of the second moving contact assembly.

[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 drive portion 50. The contact cavity 20, stationary contact assembly 30, moving assembly 40, and magnetic drive portion 50 are located within the housing 10. The stationary contact assembly 30 is mounted on the contact cavity 20, and a portion of the stationary contact assembly 30 is located within the contact chamber 24 enclosed by the contact cavity 20. The moving assembly 40 is movable relative to the contact cavity 20 for contacting or separating from the stationary contact assembly 30. The magnetic drive portion 50 is configured to drive the moving assembly 40 in response to an input signal, thereby switching the relay between a first state and a second state.

[0073] In this context, "contact" in the term "contact or separation" refers to two components being in direct or indirect contact, allowing current to flow through them. "Separation" in the term "contact or separation" refers to two components being disconnected, preventing current from flowing through them.

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

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

[0076] The following explanation will use the first state as the relay being in parallel and the second state as the relay being in series as examples, but it should not be limited to these.

[0077] As an example, such as Figure 1 and Figure 2 As shown, the outer shell 10 may include a first shell 11 and a second shell 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 drive portion 50. The shape of the first shell 11 and the second shell 12 connected together can be a cuboid, a cylinder, etc. In the embodiment of this application, the first shell 11 and the second shell 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 rectangular parallelepipeds 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.

[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 2 and Figure 3 As shown, the contact cavity 20 includes a separately connected top cover 21, a cover wall 22, and a yoke 23. The cover wall 22 is a cylindrical structure with openings at both ends. The top cover 21 closes one opening of the cover wall 22, and the yoke 23 closes the other opening of the cover wall 22. The top cover 21, the cover wall 22, and the yoke 23 together form a contact chamber 24. The static contact assembly 30 is mounted on the top cover 21.

[0081] It is understood that the closed ring formed by the cylindrical structure can be circular, polygonal, elliptical, etc., and this application does not limit it.

[0082] In one embodiment, the dome 21 is generally flat and parallel to the yoke 23, but this is not a limitation. For example, in other embodiments, the dome 21 may also be L-shaped.

[0083] In one embodiment, the yoke 23 is a flat plate structure. The yoke 23 has a through hole 231 that extends through the yoke 23 along its thickness direction. The moving component 40 is movably disposed within the through hole 231, and a portion of the moving component 40 is located within the contact chamber 24.

[0084] like Figure 2 and Figure 3 As shown, the moving component 40 includes a push rod component 41 and a moving contact component 42. The moving contact component 42 is located in the contact chamber 24 and is mounted on the push rod component 41. The push rod component 41 is movably inserted into the through hole 231 and is used to drive the moving contact component 42 to move so that the moving contact component 42 contacts or separates from the stationary contact component 30.

[0085] The magnetic drive part 50 is located on the side of the yoke 23 facing away from the static contact assembly 30 and is connected to the push rod member 41 for driving the push rod member 41 to move.

[0086] It is understood that the magnetic drive part 50 can be a magnetic holding structure or a non-magnetic holding structure, and this application does not limit it in this regard.

[0087] like Figures 3 to 5As shown, the stationary contact assembly 30 includes a stationary component 31 and a conductive element 32 connected to the stationary component 31. The stationary component 31 is mounted on the top cover 21, and the conductive element 32 is connected to the stationary component 31, extending from the stationary component 31 towards the yoke member 23. The conductive element 32 also has a conductive portion 32c surrounded by the cover wall 22; the conductive portion 32c is located on the side of the moving contact assembly 42 facing away from the stationary component 31, and is used to contact or separate from the moving contact assembly 42; the moving contact assembly 42 and the conductive portion 32c have overlapping areas in their respective orthogonal projections on a first target plane, and the first target plane is perpendicular to the direction of movement of the push rod member 41.

[0088] The relay of this application embodiment has a contact cavity 20 including a separately connected top cover 21, a cover wall 22, and a yoke 23. When assembling the contact cavity 20, the stationary contact assembly 30, and the moving contact assembly 42, the stationary contact assembly 30 can be connected to the top cover 21 first, and then the moving contact assembly 42 can be installed from the side of the stationary contact assembly 30 between the stationary part 31 and the conductive part 32c. Finally, the cover wall 22 and the yoke 23 can be connected to the top cover 21 so that the top cover 21, the cover wall 22, and the yoke 23 surround the moving contact assembly 42. The relay in this embodiment of the application designs the contact cavity 20 as a separate top cover 21, cover wall 22 and yoke iron 23, which can realize the effect of the moving contact assembly 42 being installed between the stationary part 31 and the conductive part 32c from the side of the stationary contact assembly 30. This avoids the interference problem of the conductive part 32c that occurs when the moving contact assembly 42 is installed between the stationary part 31 and the conductive part 32c along the movement direction of the moving contact assembly 42. At the same time, the volume of the contact cavity 20 does not need to be designed to be too large, which is conducive to the miniaturization design of the product.

[0089] It should be noted that the extension of the self-static component 31 of the conductive component 32 toward the yoke component 23 means that the conductive component 32 as a whole has a tendency to move closer to the yoke component 23, which may include, but is not limited to: the conductive component 32 extending in a straight line toward the yoke component 23, the conductive component 212 extending in a curve toward the yoke component 23, etc.

[0090] In one embodiment, the conductive part 32c is located on the side of the moving contact assembly 42 away from the stationary part 31 along the direction of movement of the moving contact assembly 42.

[0091] In one embodiment, the conductive member 32 includes a receiving cavity 326 with a notch 325 facing the cover wall 22, and the moving contact assembly 42 can be inserted into the receiving cavity 326 through the notch 325 from the side of the stationary contact assembly 30.

[0092] like Figure 2 and Figure 3As shown in the figure, as an example, the canopy 21 includes a top plate 211 and a frame piece 212, which is connected to the top plate 211 and the canopy wall 22 respectively, and the stationary component 31 is installed on the top plate 211. The frame piece 212 is a metal part with a ring structure.

[0093] In one embodiment, the top plate 211 is made of ceramic material, and the frame plate 212 and the cover wall 22 are made of metallic material. For example, the frame plate 212 and the cover wall 22 may be made of an iron-nickel alloy, but are not limited thereto.

[0094] like Figures 3 to 5 As shown, the stationary component 31 includes four leads, namely two first leads 311 and two second leads 312, both of which are mounted on the top cover 21. The two first leads 311 and the two second leads 312 are arranged at intervals along a first direction D1. The positions of the two first leads 311 and the two second leads 312 correspond respectively in a third direction D3. The direction of movement of the push rod component 41 is defined as a second direction D2, and the first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other.

[0095] In one embodiment, when the relay is in a first state, two of the four leads form a first conductive path. When the relay is in a second state, the four leads form two second conductive paths.

[0096] In the embodiments of this application, the two first leads 311 and the two second leads 312 form a rectangle. Further, the two first leads 311 and the two second leads 312 can form a square.

[0097] Of course, in other embodiments, the two first leads 311 may not correspond to the positions of the two second leads 312 on the third direction D3. For example, the two first leads 311 and the two second leads 312 form a trapezoid. Further, the trapezoid can be an isosceles trapezoid, a right trapezoid, or a general trapezoid.

[0098] For ease of explanation later, the two first leads 311 are defined as A1 and A2, and the two second leads 312 are defined as B1 and B2. On the third direction D3, A1 and B1 are in the same position, and A2 and B2 are in the same position.

[0099] like Figure 5As shown, the conductive element 32 includes a first conductive element 32a and a second conductive element 32b arranged at intervals. The first conductive element 32a is connected to one of the first leads 311, and the second conductive element 32b is connected to one of the second leads 312. The space between the first conductive element 32a and the second conductive element 32b is a receiving cavity 326, and the same edge of the first conductive element 32a and the second conductive element 32b forms a notch 325. The moving contact assembly 42 is located between the first conductive element 32a and the second conductive element 32b.

[0100] In one embodiment, the first lead-out 311 connected to the first conductive member 32a and the second lead-out 312 connected to the second conductive member 32b are arranged diagonally. In this embodiment, the first conductive member 32a is connected to A1, and the second conductive member 32b is connected to B2. A1 and B2 are arranged diagonally.

[0101] Of course, in other embodiments, the first conductive element 32a may be connected to A2 and the second conductive element 32b may be connected to B1; or, the first conductive element 32a may be connected to A1 and the second conductive element 32b may be connected to B1; or, the first conductive element 32a may be connected to A2 and the second conductive element 32b may be connected to B2.

[0102] The conductive part 32c includes a first conductive part 322 and a second conductive part 324. The first conductive member 32a has the first conductive part 322, and the second conductive member 32b has the second conductive part 324. When the relay is in the second state, the moving contact assembly 42 is in contact with the first conductive part 322 and the second conductive part 324 at the same time.

[0103] The moving contact assembly 42 includes a first moving contact assembly 42a and a second moving contact assembly 42b, which are arranged side-by-side along a third direction D3. When the external circuit controlled by the relay is in parallel, the two first leads 311 are connected in series through the first moving contact assembly 42a to form a second conductive path, and the two second leads 312 are connected in series through the second moving contact assembly 42b to form another second conductive path. The two first leads 311 connected in series are connected in parallel with the two second leads 312 connected in series. When the external circuit controlled by the relay is in series, both ends of the first moving contact assembly 42a and both ends of the second moving contact assembly 42b are simultaneously in contact with the first conductive part 322 and the second conductive part 324, so that A1 and B2 are connected in series.

[0104] In one embodiment, the length direction of the first moving contact component 42a and the length direction of the second moving contact component 42b are both parallel to the first direction D1.

[0105] In one embodiment, the first moving contact component 42a and the second moving contact component 42b are arranged side by side on a third direction D3.

[0106] The first moving contact component 42a may include one or more moving contact elements 421, and the second moving contact component 42b may include one or more moving contact elements 421.

[0107] like Figures 5 to 7 As shown, the first conductive member 32a further includes a first connecting portion 321, and a first conductive portion 322 is connected to the first connecting portion 321. The first connecting portion 321 is connected to the side surface of one of the first leads 311 facing the yoke member 23. The second conductive member 32b further includes a second connecting portion 323, and a second conductive portion 324 is connected to the second connecting portion 323. The second connecting portion 323 is connected to the side surface of one of the second leads 312 facing the yoke member 23.

[0108] In the embodiments of this application, the first connecting portion 321 is connected to one of the first leads 311 on the side surface facing the yoke 23, and the second connecting portion 323 is connected to one of the second leads 312 on the side surface facing the yoke 23, such that the first conductive element 32a is connected to the bottom surface of the first lead 311 instead of the side surface, and the second conductive element 32b is connected to the bottom surface of the second lead 312 instead of the side surface. This can reduce the space occupied by the conductive elements on the side of the moving contact assembly to a certain extent, which is beneficial to the miniaturization design of the product.

[0109] Of course, in other embodiments, the first connecting part 321 may also be connected to the outer peripheral side of the first lead-out member 311, and the second connecting part 323 may be connected to the outer peripheral side of the second lead-out member 312.

Similarly, the third segment 3231 is connected to the surface of one of the second leads-out members 312 facing the yoke 23, and the surface of the third segment 3231 facing the yoke 23 is flush with the surface of the other second lead-out member 312 facing the yoke 23, so that the second conductive member 32b does not occupy too much volume in the direction of movement (second direction D2) of the moving assembly 40.

[0113] Furthermore, the surface of the first segment 3211 facing the yoke 23 is flush with the surface of the other first lead-out member 311 facing the yoke 23, and the surface of the third segment 3231 facing the yoke 23 is flush with the surface of the other second lead-out member 312 facing the yoke 23, which improves the consistency and reliability of the contact between the two ends of the first moving contact assembly 42a and the two ends of the second moving contact assembly 42b.

[0114] In one embodiment, the second segment 3212 and the fourth segment 3232 are respectively located on both sides of the first moving contact assembly 42a along the first direction D1, and the second segment 3212 and the fourth segment 3232 are respectively located on both sides of the second moving contact assembly 42b along the first direction D1.

In other words, the first conductive element 32a and the second conductive element 32b are approximately C-shaped.

[0116] like Figure 5 As shown, in one embodiment, the first conductive element 32a and the second conductive element 32b are arranged symmetrically. Further, the first conductive element 32a and the second conductive element 32b are arranged in a centrally symmetrical manner.

[0117] Of course, in other embodiments, the first conductive element 32a and the second conductive element 32b may also be arranged in an axisymmetric manner.

[0140] In summary, the relay and its assembly method according to the embodiments of this application have at least the following advantages and beneficial effects:

[0141] The relay of this application embodiment has a contact cavity 20 comprising a separately connected top cover 21, a cover wall 22, and a yoke 23. The conductive element of the stationary contact assembly 30 includes a receiving cavity 326 with a notch 325 facing the cover wall 22. When assembling the contact cavity 20, the stationary contact assembly 30, and the moving assembly 40, the stationary contact assembly 30 can be connected to the top cover 21 first. Then, the moving contact assembly 42 of the moving assembly 40 can be inserted into the receiving cavity 326 through the notch 325 from the side of the stationary contact assembly 30. Finally, the cover wall 22 and the yoke 23 can be connected to the top cover 21 so that the top cover 21, the cover wall 22, and the yoke 23 surround the moving contact assembly 42. The relay in this embodiment of the application designs the contact cavity 20 as a separate cover top 21, cover wall 22 and yoke iron 23, which can realize the effect of the moving component 40 being installed into the receiving cavity 326 of the conductive component from the side of the stationary contact component 30. This avoids the problem of interference of conductive parts that occurs when the moving component 40 is installed into the receiving cavity 326 along the axial direction. At the same time, the volume of the contact cavity 20 does not need to be designed to be too large, which is conducive to the miniaturization design of the product.

[0142] Furthermore, the first connecting portion 321 is connected to one of the first leads 311 on the side surface facing the yoke 23, and the second connecting portion 323 is connected to one of the second leads 312 on the side surface facing the yoke 23, so that the first conductive element 32a is connected to the bottom surface of the first lead 311 instead of the side surface, and the second conductive element 32b is connected to the bottom surface of the second lead 312 instead of the side surface. This can reduce the space occupied by the conductive elements on the side of the moving contact assembly 42 to a certain extent, which is beneficial to the miniaturization design of the product.

[0143] Furthermore, the first segment 3211 is connected to the surface of the first lead-out member 311 facing the yoke 23, and the surface of the first segment 3211 facing the yoke 23 is flush with the surface of the other first lead-out member 311 facing the yoke 23, so that the first conductive member 32a does not occupy too much volume in the direction of movement (second direction D2) of the moving assembly 40. Similarly, the third segment 3231 is connected to the surface of one of the second leads-out members 312 facing the yoke 23, and the surface of the third segment 3231 facing the yoke 23 is flush with the surface of the other second lead-out member 312 facing the yoke 23, so that the second conductive member 32b does not occupy too much volume in the direction of movement (second direction D2) of the moving assembly 40. Therefore, the static contact assembly 30 of this embodiment includes more compact leads and conductive members after assembly, improving space utilization.

[0144] Furthermore, the surface of the first segment 3211 facing the yoke 23 is flush with the surface of the other first lead-out member 311 facing the yoke 23, and the surface of the third segment 3231 facing the yoke 23 is flush with the surface of the other second lead-out member 312 facing the yoke 23, which improves the consistency and reliability of the contact between the two ends of the first moving contact assembly 42a and the two ends of the second moving contact assembly 42b.
