In the static contact assembly proposed in this application, the conductive and connecting components are made of different materials. The connecting component does not participate in conductivity, therefore its conductivity requirement is lower. Thus, materials with lower conductivity and lower cost for the connecting component can be selected, further saving costs.

[0024] The contact assembly proposed in this application employs a two-piece static contact assembly, eliminating the need for head flattening in the mold used during its fabrication. This simplifies the mold structure and facilitates manufacturing. The connector and conductive component are made of different materials; the connector does not participate in conductivity, thus requiring lower conductivity. Therefore, a lower-conductivity, cheaper material can be selected, reducing the manufacturing cost of the contact assembly.

[0025] The relay proposed in this application uses the above-mentioned contact components, which eliminates the need for head flattening when manufacturing the stationary contact component, resulting in a simpler mold structure and easier manufacturing. Since the connectors of the stationary contact component do not participate in conductivity, the corresponding conductivity requirements are lower. Therefore, materials with lower conductivity and lower cost can be selected, saving on relay manufacturing costs. Attached Figure Description

Detailed Implementation

[0035] 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.

[0036] In the following description of various exemplary embodiments of this application, reference is made to the accompanying drawings, which form part of this application, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this application. It should be understood that other specific solutions to components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this application. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this application, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this application.

[0037] 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.

[0038] As used herein, “about,” “approximately,” “essentially,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or, for example, within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” “essentially,” or “substantially” herein may be chosen to select a more acceptable range of deviations or standard deviations depending on the nature of the measurement, the cutting nature, or other properties, and may not require a single standard deviation to apply to all properties.

[0039] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being “down” to another element will be oriented “up” to that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being “below” or “under” another element will be oriented “above” that element. Thus, the exemplary terms “above” or “below” can include both “up” and “down” orientations.

Therefore, variations in the shape of the illustrations can be expected as a result of, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, the acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of this application.

[0041] See Figures 1 to 4 The illustration represents the static contact assembly 1 of this application, comprising a conductive element 10 and a connector 20. The conductive element 10 includes a first surface 101 and a second surface 102. A static contact 30 is disposed on the first surface 101, located at the end of the conductive element 10 in a first direction D. The static contact 30 being located at the end of the conductive element 10 in the first direction D, where the first direction is the length direction of the static contact assembly, eliminates the need for flattening the head of the mold used in manufacturing the static contact assembly 1, simplifying the mold structure. The connector 20 is connected to the second surface 102 of the conductive element 10 and extends away from the conductive element 10 along the first direction D. An outlet end 3 is connected to the end of the conductive element 10 not connected to the connector 20. The connector 20 and the conductive element 10 are made of different materials. The connector 20 does not need to participate in conductivity and can be made of a material with low conductivity and lower cost, avoiding waste of conductive material, saving material, and reducing costs. The connector 20 and the conductive element 10 are connected at the stationary contact 30, which can ensure the firmness and stability of the connection between the connector 20 and the conductive element 10, while also minimizing the overlap of the conductive element 10 in the connector 20, which can further save materials and reduce costs.

[0042] In this embodiment, the connector 20 and the conductive element 10 can be riveted together using the stationary contact 30, eliminating the need for an additional riveting lug 401. This further simplifies the structure, reduces costs, and saves on production steps. In this embodiment, the conductivity of the connector 20 is lower than that of the conductive element 10. Since the connector 20 does not need to participate in conduction, a cheaper material with lower conductivity can be used, thus reducing costs and avoiding waste of conductive materials.

[0043] The static contact assembly 1 provided in this application features a split design, with the conductive and non-conductive parts being independent components. The static contact 30 is located at the end of the conductive component 10 in the first direction D. This eliminates the need for flattening the head of the mold used in manufacturing the static contact assembly 1, simplifying the mold structure and thus the manufacturing process. The connector 20 does not need to participate in conductivity, so it can be made of a material with low conductivity and lower cost, avoiding waste of conductive material, saving material, and reducing costs.

[0044] In this embodiment, the stationary contact assembly 1 further includes a first magnetic conductor 40, which is disposed on the connector 20 and located on the same side of the connector 20 as the conductive component 10. The first magnetic conductor 40 prevents the stationary contact assembly 1 and the moving contact assembly 2 from instantly snapping apart and causing a safety accident when the relay is short-circuited.

[0045] In this embodiment, the connector 20 and the first magnetic conductor 40 are separate structures. The separate structure allows for the separate fabrication of the connector 20 and the first magnetic conductor 40, simplifying the manufacturing process and operation. Since the connector 20 and the first magnetic conductor 40 are made of the same material, the connector 20 can function as part of the first magnetic conductor 40, thereby reducing the thickness of the first magnetic conductor 40, further saving material and lowering costs.

[0046] The conductive component 10 is made of copper, silver, gold, aluminum, tungsten, zinc, nickel, or lithium, while the connector 20 is made of iron, silicon steel, or a nickel-iron alloy. In this embodiment, the conductive component 10 can be made of copper, and the connector 20 can be made of iron. This reduces costs, and iron has magnetic properties. The iron connector 20 can act as part of the first magnetic conductor 40, thereby reducing the thickness of the first magnetic conductor 40 and saving materials.

[0047] In this embodiment, the first magnetic conductor 40 is provided with a protrusion 401; the connector 20 is riveted to the first magnetic conductor 40 via the protrusion 401. The use of the protrusion 401 for riveting results in a simple structure and a strong connection.

[0048] In this embodiment, the connector 20 and the conductive element 10 are riveted together by the stationary contact 30. This eliminates the need for additional riveting components, further simplifying the structure, saving materials, and reducing costs.

[0049] In this embodiment, the connector 20 includes a hollow structure 203, with at least a portion of the first magnetic conductor 40 covering at least a portion of the hollow structure 203. The design of the hollow structure 203 can reduce the weight of the connector 20 and reduce the material required for the connector 20, further saving material and reducing production costs.

[0050] like Figure 5 , Figure 6 and Figure 8 As shown, the contact assembly of this application includes a moving contact assembly 2 and a stationary contact assembly 1. The moving contact assembly 2 includes a moving spring 21 and a moving contact 22. The moving contact 22 is disposed on the moving spring 21, and the moving spring 21 can drive the moving contact 22 to contact or disconnect from the stationary contact 30.

[0051] The contact assembly of this application features a two-part design for the stationary contact assembly 1, separating the conductive and non-conductive parts. The stationary contact 30 is positioned at the end of the conductive component 10 in the first direction D. This design eliminates the need for flattening the head of the mold used in manufacturing the stationary contact assembly 1, resulting in a simpler mold structure and easier manufacturing. The connector 20 and the conductive component 10 are made of different materials. Since the connector 20 does not participate in conductivity, a cheaper material with lower conductivity can be used, avoiding waste of conductive material and reducing costs.

[0052] In this embodiment, the moving contact assembly 2 further includes a second magnetic conductor 23, which is disposed on the moving spring 21 and located on the same side of the moving contact 22 as the moving contact 22. The first magnetic conductor 40 and the second magnetic conductor 23 are disposed opposite each other and have a distance between them, with at least one limiting structure 4 disposed between the first magnetic conductor 40 and the second magnetic conductor 23. When current flows through the contact assembly, a large attractive force is generated between the second magnetic conductor 23 and the first magnetic conductor 40, potentially causing them to attract together. The limiting structure 4 prevents the first magnetic conductor 40 and the second magnetic conductor 23 from attracting together. Since the magnetism of the first magnetic conductor 40 and the second magnetic conductor 23 is generated by the current, the magnitude of the attractive force between them can be adjusted according to the current magnitude. When the attractive force between the first magnetic conductor 40 and the second magnetic conductor 23 is constant, the magnetic gap between them can also be set according to the current magnitude. The magnetic gap refers to the very short air distance between the first magnetic conductor 40 and the second magnetic conductor 23. Generally speaking, under the same current, the larger the magnetic gap, the smaller the attraction force. The limiting structure 4 is used to mechanically limit the magnetic gap between the first magnetic conductor 40 and the second magnetic conductor 23 to a preset value. By increasing the magnetic gap, the electromagnetic attraction force between the two is reduced, avoiding structural interference or abnormal operation caused by excessive attraction force (such as causing excessive deformation of the moving spring).

[0053] In this embodiment, the limiting structure 4 is a plate-shaped structure and is fixed to the first magnetic conductor 40. In other embodiments, the limiting structure 4 can also be fixed to the second magnetic conductor 23, or to other structures (such as a base), as long as it is located between the first magnetic conductor 40 and the second magnetic conductor 23.

[0054] Figure 7 Another embodiment of the limiting structure 4 of this application is shown. Figure 7 The embodiments shown and Figure 6 The only difference in the illustrated embodiments is the spacing structure 4, which is a separate rod-shaped structure. In this application, there are no requirements regarding the shape or number of the spacing structures 4, as long as they can limit the minimum distance between the first magnetic conductor 40 and the second magnetic conductor 23 when they attract each other. The spacing structure 4 is made of an insulating material.

[0055] In this embodiment, the moving spring assembly 2 includes a compression spring, the fixed part of the compression spring is fixedly connected to the moving contact 22, and the compression spring includes at least two layers of spring sheets. When the thickness of the compression spring is the same, the multiple layers of spring sheets can reduce the reaction force, thereby increasing the response speed, reducing power consumption, and improving the stability of the relay.

[0056] like Figure 5 , Figure 6 and Figure 8 As shown, the relay of this application includes a base 5 and more contact components, with the contact components disposed on the base 5. The relay also includes a sampling signal line connection structure 6. In this embodiment, the sampling signal line connection structure 6 is riveted to the contact components and electrically connected to them. In other embodiments, the sampling signal line connection structure 6 may also be plugged into the contact components. The sampling signal line is a detection line led out from the relay or its supporting module, used to acquire electrical signals related to the relay's operating state or the main circuit without damaging the main circuit, for monitoring, control, metering, and protection purposes. The sampling signal line connection structure 6 electrically connects the contact components and the sampling signal line for signal transmission. Since the sampling signal line connection structure provided in this embodiment is set independently of the contact components, it can further reduce consumables and lower costs.

[0057] In this embodiment, the static contact component 1 is disposed on the base 5. A locking block 201 is provided at the end of the connector 20 away from the conductive element 10 along the first direction D. The locking block 201 engages with the base 5. A positioning block 202 is provided on the surface of the connector 20 facing away from the conductive element 10. A positioning groove 51 is provided on the base 5 at a position corresponding to the positioning block 202. When the contact component is installed in the base, the positioning block 202 of the connector 20 is positioned in the positioning groove 51. The positioning groove 51 and the positioning block 202 are in a clearance fit. One surface of the locking block 201 abuts against the base 5, and the other surface is abutted by an arc-shaped protrusion on the base 5. There are two locking blocks 201 and two positioning blocks 202. The number of positioning blocks 202 and locking blocks 201 is not limited in this application.

Figures 1 to 8 The differences between the static contact assembly 1 in the third embodiment will be explained. In the first embodiment, a protrusion 401 is disposed on the first magnetic conductor 40, and a hole for mounting the protrusion 401 is provided on the connector 20; in the static contact assembly 1 of the third embodiment, the protrusion 401 is disposed on the connector 20, and the hole for mounting the protrusion 401 is provided on the first magnetic conductor 40.

[0060] The static touch component 1 of this application also has a fourth embodiment, wherein the static touch component 1 of the fourth embodiment is related to... Figures 1 to 8 Compared to the static touch assembly 1 of the previous embodiment, it has a substantially the same structure in its basic construction.

[0061] In summary, the static contact assembly proposed in this application includes a conductive element and a connector. The conductive element includes a first surface and a second surface. A static contact is disposed on the first surface, located at the end of the conductive element in a first direction. The connector is connected to the second surface of the conductive element and extends away from the conductive element along the first direction of the static contact assembly. The connector and the conductive element are made of different materials. The static contact assembly proposed in this application has a two-part design, separating the conductive and non-conductive parts. The static contact is located at the end of the conductive element in the first direction, which eliminates the need for flattening the head of the mold used in manufacturing the static contact assembly. This simplifies the mold structure, thereby simplifying the manufacturing process and improving production efficiency. In addition, the two-part structure of the static contact assembly provides a basis for reducing the thickness of the first magnetic conductor of the static contact assembly, further saving materials. In the static contact assembly proposed in this application, the conductive element and the connector are made of different materials. The connector does not participate in conduction, so the corresponding requirement for conductivity is lower. Therefore, a lower conductivity and cheaper material can be selected, saving costs.

[0062] The contact assembly proposed in this application includes a moving contact assembly and the aforementioned stationary contact assembly. The moving contact assembly includes a moving spring and a moving contact. The moving contact is disposed on the moving spring, which can drive the moving contact to contact or disconnect with the stationary contact. The stationary contact assembly is designed in two parts, separating the conductive and non-conductive parts. The stationary contact is located at the end of the stationary contact assembly in the first direction, which eliminates the need for flattening the head of the mold used in manufacturing the stationary contact assembly, resulting in a simple mold structure and convenient manufacturing. The connecting parts and conductive parts are made of different materials. The connecting parts do not participate in conductivity, so the corresponding conductivity requirement is lower. Therefore, a lower conductivity and cheaper material can be selected, which can save on the manufacturing cost of the contact assembly.

[0063] The contact assembly proposed in this application exhibits an inverse relationship between the magnetic gap and the electromagnetic attraction force under the same excitation current. The mechanical limitation of the minimum magnetic gap by the limiting structure ensures that the electromagnetic attraction force between the first and second magnetic conductors has a stable lower threshold, preventing overload of the attraction force due to an unexpected reduction in the magnetic gap. Matching the spring reaction force to the electromagnetic attraction force at this threshold ensures that the electromagnetic attraction force can stably overcome the spring reaction force to drive the two magnetic conductors to complete the attraction action, while also allowing the spring to provide sufficient reset thrust after the excitation is de-energized to drive the two magnetic conductors to separate and reset.

[0064] The relay proposed in this application includes a base and a contact assembly disposed on the base. The stationary contact assembly has a two-part structure, separating the conductive and non-conductive parts. The stationary contact head is located at the end of the stationary contact assembly in a first direction, which eliminates the need for flattening the head of the mold used when manufacturing the stationary contact assembly, resulting in a simple mold structure and convenient manufacturing. The connecting parts and conductive parts are made of different materials. The connecting parts of the stationary contact assembly do not participate in conduction, so the corresponding conductivity requirement is lower. Therefore, materials with lower conductivity and lower cost can be selected, saving on the manufacturing cost of the relay.
