Description

Technical Field

[0001] This application generally relates to a relay having a floating magnetic structure. Background Technology

[0002] In the field of electrical control, relays are widely used as a crucial control element. A conventional relay mainly consists of a stationary contact, a moving contact, an electromagnetic system, and upper and lower magnetic blocks for magnetic conduction. Its working principle is that when the electromagnetic system is energized, it generates a magnetic field that attracts the moving contact towards the stationary contact until they make contact, thus completing the circuit. At this point, the upper and lower magnetic blocks play a key role. When the stationary and moving contacts are in contact, the mutual attraction between them ensures that the moving and stationary contacts remain in close contact, effectively preventing them from separating and thus guaranteeing stable circuit continuity.

[0003] However, in existing relay designs, the upper and lower magnetic blocks are usually fixedly installed. This fixed structure has a certain drawback: it cannot flexibly adjust the attractive force between the upper and lower magnetic blocks according to actual working requirements. Utility Model Content

[0004] One of the purposes of this application is to provide a relay that can overcome at least one defect in the prior art.

[0005] One object of this application is to provide a relay in which the lower magnetic block is floating and the distance between it and the upper magnetic block can be changed during operation.

[0006] Another objective of this application is to provide a relay that can achieve a compact design and also perform multiple functions such as guiding and restraining.

[0007] According to a first aspect of this application, a relay is provided, comprising:

[0008] A stationary contact element that extends into a contact chamber defined by the housing of the relay;

[0009] A moving contact element, which is configured to move toward the stationary contact element during operation, such that the moving contact element contacts the stationary contact element to achieve circuit conduction;

[0010] A first magnetically conductive component, disposed within the contact cavity; and

[0011] A second magnetically conductive member is connected to the moving contact element and is configured to form a magnetically conductive circuit with the first magnetically conductive member when the moving contact element contacts the stationary contact element.

[0012] The second magnetically conductive member is configured to move toward the first magnetically conductive member when the moving contact element contacts the stationary contact element, thereby changing the distance between the first magnetically conductive member and the second magnetically conductive member.

[0013] By allowing the second magnetic component to move toward the first magnetic component when the moving contact element contacts the stationary contact element, the distance between the first and second magnetic components can be changed, thereby adjusting the attractive force between the first and second magnetic components.

[0014] In some embodiments of the relay, an elastic element is provided between the moving contact element and the second magnetic conductive member, such that when the moving contact element contacts the stationary contact element, the second magnetic conductive member overcomes the elastic force of the elastic element and moves toward the first magnetic conductive member.

[0015] By providing an elastic element between the moving contact element and the second magnetic conductive member, it is possible not only to adjust the distance and attraction between the first and second magnetic conductive members, but also to bias the moving contact element to maintain contact with the stationary contact element.

[0016] In some embodiments of the relay, the second magnetically conductive member is connected to the moving contact element via the elastic element.

[0017] In some embodiments of the relay, the moving contact element is located between the first magnetic conductive member and the second magnetic conductive member.

[0018] With the moving contact element positioned between the first and second magnetic conductive components, the overall arrangement of the magnetic conductive components and the contact element is more compact, and the distance between the first and second magnetic conductive components can be better controlled and adjusted, thus avoiding unexpected situations.

[0019] In some embodiments of the relay, the second magnetically conductive member is configured to move relative to the moving contact element between a first position and a second position, wherein the distance between the first magnetically conductive member and the second magnetically conductive member in the first position is greater than the distance between the first magnetically conductive member and the second magnetically conductive member in the second position, and wherein the elastic element is configured to bias the second magnetically conductive member toward the first position.

[0020] The bias voltage of the elastic element can facilitate the adjustment of the distance between the first magnetic conductive component and the second magnetic conductive component, and facilitate the reset of the second magnetic conductive component.

[0021] In some embodiments of the relay, the elastic element is a helical spring or a disc spring.

[0022] In some embodiments of the relay, the second magnetic conductive member is provided with a first receiving portion, the moving contact element is provided with a corresponding second receiving portion, and the two ends of the elastic element are respectively received at the first receiving portion and the second receiving portion.

[0023] In some embodiments of the relay, the second magnetic conductive member is provided with a first receiving portion, the elastic element includes a spring body and a deformable portion extending from the spring body, the spring body is fixed to the moving contact element, and the end of the deformable portion is received at the first receiving portion.

[0024] The spring body is fixed to the moving contact element and the first receiving part guides and constrains the movement of the deformable part, which can help adjust the distance between the second magnetic conductive member and the moving contact element and facilitate the normal operation of the elastic element.

[0025] In some embodiments of the relay, the second magnetic conductive member is formed in a U-shape, and the moving contact element is arranged between the U-shape such that when the second magnetic conductive member moves toward the first magnetic conductive member, the second magnetic conductive member is guided along the edge of the moving contact element and moves relative to the moving contact element.

[0026] By forming the second magnetic conductive member into a U-shaped structure and arranging the moving contact element between the U-shaped structures, it is possible to guide the movement of the second magnetic conductive member in the height direction and prevent the second magnetic conductive member from deviating in the width direction.

[0027] In some embodiments of the relay, the relay further includes a mounting bracket fixed to the moving contact element to movably constrain the second magnetically conductive member between the mounting bracket and the moving contact element.

[0028] The mounting bracket can movably connect the second magnetic component to the moving contact element, and can also constrain the movement of the second magnetic component, which helps to limit the range of movement of the second magnetic component.

[0029] In some embodiments of the relay, the mounting bracket has a bracket body that is fixed to the moving contact element.

[0030] In some embodiments of the relay, the two ends of the bracket body are formed with support sections configured to support the second magnetic conductive member.

[0031] In some embodiments of the relay, the second magnetic conductive member includes two protruding sections, each protruding section being formed in the form of a U-shape, the moving contact element being arranged between the two protruding sections, and the support section being arranged between two legs of the respective protruding section and configured to support the connecting portion of the respective protruding section.

[0032] In some embodiments of the relay, the second magnetically conductive member includes two abutting sections, each abutting section being connected to a corresponding leg of each of the two protruding sections, such that the two abutting sections and the two protruding sections together form a U-shaped structure.

[0033] This arrangement of the second magnetic conductive component and the mounting bracket not only achieves a compact structure, supports and constrains the second magnetic conductive component, but also guides the movement of the second magnetic conductive component along the height direction and prevents the second magnetic conductive component from deviating along the length direction.

[0034] In some embodiments of the relay, the mounting bracket has a bracket section extending from the bracket body, and the second magnetic conductive member includes an abutment section, the bracket section being configured to support the abutment section and / or guide the movement of the abutment section.

[0035] In some embodiments of the relay, the second magnetic conductor includes two abutment sections, and the mounting bracket accordingly has two bracket sections extending from opposite sides of the bracket body.

[0036] In some embodiments of the relay, the support section includes a guide portion extending from the support body and a support portion extending from an end of the guide portion opposite to the support body. The guide portion cooperates with the abutment section to guide the movement of the abutment section. The support portion is configured to support the abutment section, thereby supporting the abutment section in the height direction and preventing the second magnetic member from disengaging between the driven contact element and the mounting bracket.

[0037] In some embodiments of the relay, the abutting section is provided with a protrusion, and the supporting portion is formed with a guide recess, the guide recess cooperating with the protrusion to guide the movement of the protrusion.

[0038] The relay according to this application employs a floating magnetic conductive structure to adjust the distance between the magnetic conductive components, thereby adjusting the attractive force between them. Furthermore, by setting the magnetic conductive component associated with the moving contact element as a floating magnetic conductive component, not only can the distance be adjusted, but the elastic force of the elastic element can also be fully utilized to additionally promote contact between the stationary and moving contact elements. Moreover, the assembly of the moving contact element, mounting bracket, and magnetic conductive component forms a compact structure, fully utilizing the shape fit between the components, saving space and obtaining additional guiding and restraining effects.

[0057] The present application will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present application. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and to fully illustrate the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0058] It should be understood that the same reference numerals denote the same elements in all the accompanying drawings. For clarity, the dimensions of certain features may be modified in the drawings.

[0059] It should be understood that the terminology used in this specification is for describing specific embodiments only and is not intended to limit this application. All terms used in this specification (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0060] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features. The term “and / or” used in this specification includes any and all combinations of one or more of the related listed items. The terms “between X and Y” and “between approximately X and Y” used in this specification should be interpreted as including both X and Y. The term “between approximately X and Y” used in this specification means “between approximately X and approximately Y,” and the term “from approximately X to Y” used in this specification means “from approximately X to approximately Y.”

[0061] In the specification, when an element is described as being "on," "attached," "connected," "coupled," or "in contact" with another element, the element can be directly located on, attached to, connected to, coupled to, or in contact with the other element, or there may be intermediate elements present. Conversely, when an element is described as being "directly" located on, directly attached to, directly connected to, directly coupled to, or directly in contact with another element, no intermediate elements are present.

The device can also be oriented in other ways (rotated 90 degrees or in other orientations), in which case the relative spatial relationships will be explained accordingly.

[0063] In the field of electrical control, relays are widely used as a crucial control element. A conventional relay mainly consists of a stationary contact, a moving contact, an electromagnetic system, and upper and lower magnetic blocks for magnetic conduction. Its working principle is that when the electromagnetic system is energized, it generates a magnetic field that attracts the moving contact towards the stationary contact until they make contact, thus completing the circuit. At this point, the upper and lower magnetic blocks play a key role. When the stationary and moving contacts are in contact, the mutual attraction between them ensures that the moving and stationary contacts remain in close contact, effectively preventing them from separating and thus guaranteeing stable circuit continuity.

[0064] However, in existing relay designs, the upper and lower magnetic blocks are typically fixed in place. This fixed structure has a significant drawback: it cannot flexibly adjust the attractive force between the upper and lower magnetic blocks according to actual operating requirements. Under different electrical operating conditions, such as different voltage and current conditions, or when there are different requirements for circuit conduction stability, a fixed attractive force may not meet the optimal operating conditions.

[0065] refer to Figure 1 and Figure 2 , Figure 1 A cross-sectional perspective view of a relay 1 according to some embodiments of this application is shown. Figure 2A cross-sectional view of a relay 1 according to some embodiments of this application is shown. For clarity, the mutually orthogonal X direction (also referred to as the length direction), Y direction (also referred to as the width direction), and Z direction (also referred to as the height direction) can be defined below, such as... Figure 1 As shown, the moving contact moves along the Z direction to make contact with the stationary contact.

[0066] The relay 1 may include a stationary contact element 10 and a moving contact element 20. The stationary contact element 10 extends into a contact chamber 12 formed by the housing 11, and the moving contact element 20 is disposed in the contact chamber 12. The housing 11 may be made of materials such as plastic, ceramic, or metal, for example, polybutylene terephthalate (PBT), polycarbonate (PC), polyamide (PA), or polyoxymethylene (POM).

[0067] During the operation of relay 1, the moving contact element 20 moves along the height direction toward the stationary contact element 10 to make contact with the stationary contact element 10 within the contact chamber 12, thereby achieving circuit continuity. In the illustrated embodiment, relay 1 is shown to have two stationary contact elements 10 and one moving contact element 20, with the lead-out end of the stationary contact element 10 used to contact the moving contact element 20. Those skilled in the art will understand that other suitable forms and numbers of stationary contact elements 10 and moving contact elements 20 can also be used as needed. The stationary contact elements 10 and moving contact elements 20 can be made of conductive materials, such as silver-based alloys, copper-based alloys, precious metal materials, or any other suitable materials known in the art, such as silver-nickel, silver-cadmium oxide, silver-tin oxide, silver-tungsten, silver-plated copper, copper-chromium, gold, platinum, palladium, tungsten carbide, etc.

[0068] Typically, the relay 1 may also include a push assembly 50 configured to push the moving contact element 20 toward the stationary contact element 10 along the height direction to make contact with the stationary contact element 10. The push assembly 50 may include a base 52 and a push rod 54 connected to the base 52. A spring 56 may be provided on the side of the base 52 opposite to the push rod 54, and the spring 56 is connected to the moving contact element 20. When the coil is energized, the push rod 54 is driven to move along the height direction, which in turn pushes the moving contact element 20 to move along the height direction via the spring 56. When the moving contact element 20 contacts the stationary contact element 10, the moving contact element 20 no longer moves along the height direction. At this time, the spring 56 can buffer the driving action of the push rod 54 and maintain the contact between the moving contact element 20 and the stationary contact element 10.

[0069] When the moving contact element 20 contacts the stationary contact element 10, the circuit is turned on, and current flows through both elements. At this time, a repulsive force may be generated between the moving contact element 20 and the stationary contact element 10, tending to separate them and disengage. This repulsive force may exceed the pushing force of the actuating assembly 50 on the moving contact element 20, ultimately causing the moving contact element 20 to separate from the stationary contact element 10. In this case, to ensure contact between the actuating contact element 20 and the stationary contact element 10, a magnetically conductive member can be provided to prevent separation. Specifically, the relay 1 can be provided with a first magnetically conductive member 30 and a second magnetically conductive member 40. The first magnetically conductive member 30 can be connected to, for example, the housing 11 or the stationary contact element 10, and the second magnetically conductive member 40 can be connected to the moving contact element 20. When the moving contact element 20 contacts the stationary contact element 10, a magnetic circuit is formed between the first magnetic conductive member 30 and the second magnetic conductive member 40, thereby generating an attractive force between the first magnetic conductive member 30 and the second magnetic conductive member 40, which in turn strengthens and maintains the contact between the moving contact element 20 and the stationary contact element 10.

[0070] The relay according to this application can be used as an electrical control device and is widely applied in various fields such as power, industry, communications, and home appliances. For example, relays can be used in power systems such as substations and transmission lines; industrial automation such as motor control and production lines; communications such as switching equipment and communication power supplies; home appliances such as air conditioners and refrigerators; automotive electronics such as starting circuits and lighting control; and smart homes such as smart switches and security systems.

[0071] The following will be referenced Figures 1 to 8 The present application describes in detail a relay 1 according to some embodiments, which includes a floating magnetic member, namely a second magnetic member 40 that is movable relative to a first magnetic member 30.

[0072] According to some embodiments of this application, a relay 1 is provided, comprising: a stationary contact element 10 that extends into a contact chamber 12 defined by a housing 11 of the relay 1; a moving contact element 20 configured to move toward the stationary contact element 10 during operation, such that the moving contact element 20 contacts the stationary contact element 10 to achieve circuit conduction; a first magnetically conductive member 30 disposed within the contact chamber 12; and a second magnetically conductive member 40 connected to the moving contact element 20 and configured to form a magnetically conductive circuit with the first magnetically conductive member 30 when the moving contact element 20 contacts the stationary contact element 10. The second magnetically conductive member 40 can be configured to move toward the first magnetically conductive member 30 when the moving contact element 20 contacts the stationary contact element 10, thereby changing the distance between the first magnetically conductive member 30 and the second magnetically conductive member 40.

[0073] As mentioned above, refer to Figure 1 and Figure 2 The relay 1 may include a stationary contact element 10 and a moving contact element 20. During the operation of the relay 1, the stationary contact element 10 and the moving contact element 20 contact each other within the contact chamber 12 to achieve circuit conduction. After the stationary contact element 10 and the moving contact element 20 contact each other, it is necessary to maintain the contact between the stationary contact element 10 and the moving contact element 20 to ensure circuit conduction. However, the stationary contact element 10 and the moving contact element 20 may generate mutual repulsive force when they contact each other. Once the repulsive force exceeds the pushing force of the pushing component on the moving contact element 20, the stationary contact element 10 and the moving contact element 20 may disengage. To address this, a magnetic conductive member can be provided in the relay 1, forming a magnetic circuit between the magnetic conductive members to generate an attractive force. Specifically, the relay 1 may be provided with a first magnetically conductive member 30 and a second magnetically conductive member 40. The first magnetically conductive member 30 may be disposed within the contact chamber 12, for example, and may be connected to the housing 11 or the stationary contact element 10. The second magnetically conductive member 40 may be connected to the moving contact element 20, such that when the moving contact element 20 is pushed toward the stationary contact element 10, the second magnetically conductive member 40 moves toward the stationary contact element 10 along with the moving contact element 20. When the moving contact element 20 contacts the stationary contact element 10, a magnetic circuit is formed between the first magnetically conductive member 30 and the second magnetically conductive member 40, thereby generating an attractive force between the first magnetically conductive member 30 and the second magnetically conductive member 40, thereby enhancing and maintaining the contact between the moving contact element 20 and the stationary contact element 10. Magnetic conductive components can be made of magnetic conductive materials such as metals, ferrites, and other composite materials, such as iron, low-carbon steel, iron-silicon alloys, iron-aluminum alloys, nickel-iron alloys, cobalt alloys, soft magnetic ferrites, soft magnetic composite materials, and machinable magnetic conductive materials.

[0074] According to an embodiment of this application, the second magnetic conductive member 40 can be configured to move toward the first magnetic conductive member 30 when the moving contact element 20 contacts the stationary contact element 10, so as to change the distance between the first magnetic conductive member 30 and the second magnetic conductive member 40.

[0075] As described above, when the moving contact element 20 contacts the stationary contact element 10, a magnetic circuit is formed between the first magnetically conductive member 30 and the second magnetically conductive member 40, thereby generating an attractive force between them. With the material, shape, and size of the magnetically conductive members remaining constant, the magnitude of this attractive force is related to the magnetic field strength and the distance between the two magnetically conductive members. The magnetic field strength can be changed by altering, for example, the magnitude of the current, thus adjusting the magnitude of the attractive force between the first magnetically conductive member 30 and the second magnetically conductive member 40. However, adjusting the attractive force by, for example, changing the current magnitude may complicate the relay, increase the difficulty of control, and may also increase the failure rate, energy consumption, and cost. Therefore, this application considers adjusting the attractive force between the first magnetically conductive member 30 and the second magnetically conductive member 40 by changing the distance between them.

[0076] When the moving contact element 20 contacts the stationary contact element 10, this contact keeps the moving contact element 20 and the stationary contact element 10 relatively stationary. At this time, if both the first magnetic conductive member 30 and the second magnetic conductive member 40 are fixed magnetic conductive members, they will also remain stationary, the distance between the first magnetic conductive member 30 and the second magnetic conductive member 40 remains unchanged, and the attraction force remains unchanged. According to the embodiment of this application, when the moving contact element 20 contacts the stationary contact element 10, a magnetic circuit is formed between the first magnetic conductive member 30 and the second magnetic conductive member 40, thereby generating an attraction force between the first magnetic conductive member 30 and the second magnetic conductive member 40. This attraction force can force the second magnetic conductive member 40 to move further toward the first magnetic conductive member 30, thereby changing the distance between the first magnetic conductive member 30 and the second magnetic conductive member 40, and thus changing the attraction force between the first magnetic conductive member 30 and the second magnetic conductive member 40. As the second magnetically conductive member 40 moves further toward the first magnetically conductive member 30, the distance between the first magnetically conductive member 30 and the second magnetically conductive member 40 decreases, and the attractive force between the first magnetically conductive member 30 and the second magnetically conductive member 40 increases, thereby increasing the speed at which the second magnetically conductive member 40 moves toward the first magnetically conductive member 30.

[0077] By moving the second magnetic component 40 toward the first magnetic component 30 when the moving contact element 20 contacts the stationary contact element 10, the distance between the first magnetic component 30 and the second magnetic component 40 can be changed, thereby adjusting the attraction between the first magnetic component 30 and the second magnetic component 40.

[0078] According to some embodiments of this application, an elastic element 60 may be provided between the moving contact element 20 and the second magnetic conductive member 40, such that when the moving contact element 20 contacts the stationary contact element 10, the second magnetic conductive member 40 overcomes the elastic force of the elastic element 60 and moves toward the first magnetic conductive member 30.

[0079] like Figures 3 to 8 As shown, Figures 3 to 5 A schematic diagram of the floating structure of relay 1 in some embodiments is shown. Figures 4 to 8 A schematic diagram of a floating structure for relay 1 in other embodiments is shown. For example... Figures 3 to 5 As shown, the elastic element 60 is in the form of a helical spring. In the illustrated embodiment, two helical springs are shown, but those skilled in the art should understand that any suitable number of helical springs can be used according to the actual application requirements. The elastic element 60 is disposed between the moving contact element 20 and the second magnetic conductive member 40. When the moving contact element 20 is in contact with the stationary contact element 10, the second magnetic conductive member 40 continues to move towards the first magnetic conductive member 30. Since the moving contact element 20 remains stationary, the second magnetic conductive member 40 also moves relative to the moving contact element 20, specifically towards (in the illustrated embodiment) or away from (not shown) the moving contact element 20. The elastic element 60 between the moving contact element 20 and the second magnetic conductive member 40 is compressed (in the illustrated embodiment) or stretched (not shown) to generate a spring force. Therefore, the second magnetic conductive member 40 needs to overcome the spring force of the elastic element 60 and move towards the first magnetic conductive member 30. Specifically, the attraction between the first magnetic conductive member 30 and the second magnetic conductive member 40 overcomes the spring force of the elastic element 60, causing the second magnetic conductive member 40 to move towards the first magnetic conductive member 30.

[0080] like Figures 6 to 7As shown, the elastic element 60 is in the form of a butterfly spring. In the illustrated embodiment, only one butterfly spring is shown, but those skilled in the art should understand that any suitable number of butterfly springs can be used depending on the actual application requirements. The elastic element 60 is disposed between the moving contact element 20 and the second magnetically conductive member 40. When the moving contact element 20 is in contact with the stationary contact element 10, the second magnetically conductive member 40 continues to move towards the first magnetically conductive member 30. Since the moving contact element 20 remains stationary, the second magnetically conductive member 40 also moves relative to the moving contact element 20, specifically towards (in the illustrated embodiment) the moving contact element 20. The elastic element 60 between the moving contact element 20 and the second magnetically conductive member 40 generates a spring force due to elastic deformation. Therefore, the second magnetically conductive member 40 needs to overcome the spring force of the elastic element 60 and move towards the first magnetically conductive member 30. Specifically, the attraction between the first magnetically conductive member 30 and the second magnetically conductive member 40 overcomes the spring force of the elastic element 60, causing the second magnetically conductive member 40 to move towards the first magnetically conductive member 30. In the magnetic circuit formed by the first magnetically conductive member 30 and the second magnetically conductive member 40, the current generates a magnetic field, which in turn generates an attractive force. Therefore, the current and the attractive force are related. In this case, the elastic element 60 can be designed in relation to the current in the magnetic circuit. For example, when the current in the magnetic circuit reaches the current threshold, the attractive force generated between the first magnetically conductive member 30 and the second magnetically conductive member 40 overcomes the elastic force of the elastic element 60, causing the second magnetically conductive member 40 to begin moving toward the first magnetically conductive member 30.

[0081] As described above, when the moving contact element 20 contacts the stationary contact element 10, and the second magnetic conductive member 40 continues to move toward the first magnetic conductive member 30, the elastic element 60 between the moving contact element 20 and the second magnetic conductive member 40 generates a spring force, which in turn helps to bias the moving contact element 20 to maintain contact with the stationary contact element 10.

[0082] By providing an elastic element 60 between the moving contact element 20 and the second magnetic conductive member 40, it is possible not only to help adjust the distance and attraction between the first magnetic conductive member 30 and the second magnetic conductive member 40, but also to help bias the moving contact element 20 to maintain contact with the stationary contact element 10.

[0083] According to some embodiments of this application, the second magnetic conductive member 40 can be connected to the moving contact element 20 via an elastic element 60.

[0084] The elastic element 60 can be connected to the second magnetic component 40 and the moving contact element 20 by various suitable methods such as threaded connection or welding, thereby connecting the second magnetic component 40 to the moving contact element 20, so as to facilitate the movement of the second magnetic component 40 and the moving contact element 20 together.

[0085] According to some embodiments of this application, the moving contact element 20 may be located between the first magnetic conductive member 30 and the second magnetic conductive member 40.

[0086] In the illustrated embodiment, the moving contact element 20 is located between the first magnetically conductive member 30 and the second magnetically conductive member 40, that is, the first magnetically conductive member 30 and the second magnetically conductive member 40 are respectively located on opposite sides of the moving contact element 20. Thus, when the second magnetically conductive member 40 moves toward the first magnetically conductive member 30 when the moving contact element 20 contacts the stationary contact element 10, the second magnetically conductive member 40 also moves toward the moving contact element 20. The elastic element 60 between the moving contact element 20 and the second magnetically conductive member 40 is compressed or undergoes elastic deformation to generate an elastic force, which then biases the moving contact element 20 toward the stationary contact element 10.

[0087] Those skilled in the art will understand that, in embodiments not shown, the second magnetically conductive member 40 may also be positioned between the moving contact element 20 and the first magnetically conductive member 30, i.e., the moving contact element 20 and the first magnetically conductive member 30 are respectively located on opposite sides of the second magnetically conductive member 40. Thus, when the second magnetically conductive member 40 moves toward the first magnetically conductive member 30 when the moving contact element 20 contacts the stationary contact element 10, the second magnetically conductive member 40 moves away from the moving contact element 20. The elastic element 60 between the moving contact element 20 and the second magnetically conductive member 40 is stretched or undergoes elastic deformation to generate a spring force. This spring force then pulls the moving contact element 20 toward the stationary contact element 10 to help maintain contact between the moving contact element 20 and the stationary contact element 10.

[0088] When the moving contact element 20 is positioned between the first magnetically conductive member 30 and the second magnetically conductive member 40, the overall arrangement of the magnetically conductive member and the contact element is more compact, and the distance between the first magnetically conductive member 30 and the second magnetically conductive member 40 can be better controlled and adjusted to avoid accidents.

[0089] According to some embodiments of this application, the second magnetic conductive member 40 may be configured to move relative to the moving contact element 20 between a first position and a second position, wherein the distance between the first magnetic conductive member 30 and the second magnetic conductive member 40 in the first position is greater than the distance between the first magnetic conductive member 30 and the second magnetic conductive member 40 in the second position, wherein the elastic element 60 is configured to bias the second magnetic conductive member 40 toward the first position.

[0090] Before the moving contact element 20 contacts the stationary contact element 10, the second magnetically conductive member 40 does not move relative to the moving contact element 20, and the second magnetically conductive member 40 is in a first position. In the illustrated embodiment, when the moving contact element 20 is between the first magnetically conductive member 30 and the second magnetically conductive member 40, the distance between the second magnetically conductive member 40 and the moving contact element 20 is at its maximum in the first position. However, when the second magnetically conductive member 40 can also be between the moving contact element 20 and the first magnetically conductive member 30, the distance between the second magnetically conductive member 40 and the moving contact element 20 is at its minimum in the first position. When the moving contact element 20 contacts the stationary contact element 10, the second magnetically conductive member 40 overcomes the elastic force of the elastic element 60 and continues to move toward the first magnetically conductive member 30. In the illustrated embodiment, the second magnetically conductive member 40 also moves toward the moving contact element 20, reducing the distance between the second magnetically conductive member 40 and the moving contact element 20, and also reducing the distance between the first magnetically conductive member 30 and the second magnetically conductive member 40. However, if the second magnetically conductive member 40 can also be positioned between the moving contact element 20 and the first magnetically conductive member 30, the second magnetically conductive member 40 moves away from the moving contact element 20, increasing the distance between the second magnetically conductive member 40 and the moving contact element 20, and decreasing the distance between the first magnetically conductive member 30 and the second magnetically conductive member 40. When the attraction between the first magnetically conductive member 30 and the second magnetically conductive member 40 is finally balanced by the elastic force of the elastic element 60, or when the movement of the second magnetically conductive member 40 toward the first magnetically conductive member 30 is hindered (e.g., by the passive contact element 20), the distance between the first magnetically conductive member 30 and the second magnetically conductive member 40 reaches its minimum distance, and the second magnetically conductive member 40 is in the second position.

[0091] In the first position, the elastic element 60 has the smallest elastic deformation and generates the smallest elastic force. In the second position, the elastic element 60 has the largest elastic deformation and generates the largest elastic force. The elastic element 60 biases the second magnetic conductive member 40 toward the first position.

[0092] The bias voltage of the elastic element 60 can facilitate the adjustment of the distance between the first magnetic conductive member 30 and the second magnetic conductive member 40, and facilitate the reset of the second magnetic conductive member 40.

[0093] According to some embodiments of this application, a first receiving portion 42 may be provided on the second magnetic conductive member 40, and a corresponding second receiving portion 22 may be provided on the moving contact element 20. The two ends of the elastic element 60 may be received at the first receiving portion 42 and the second receiving portion 22, respectively.

[0094] like Figures 3 to 5As shown, the elastic element 60 is in the form of a helical spring. The second magnetically conductive member 40 may be formed with an abutment section 44, on which the elastic element 60 may abut. A first receiving portion 42 for receiving the elastic element 60 may be formed on the abutment section 44. The first receiving portion 42 may be in the form of, for example, a recess or groove, into which one end of the elastic element 60 in the form of a helical spring may be received.

[0095] like Figure 4 and Figure 5 As shown, a second receiving portion 22 can be formed on the moving contact element 20 at a position corresponding to the first receiving portion 42. The second receiving portion 22 can also be in the form of, for example, a recess or groove, and the other end of the elastic element 60 in the form of a helical spring can be received in the recess or groove.

[0096] The above description of the first receiving portion 42 and the second receiving portion 22 is merely exemplary. Those skilled in the art will understand that the receiving portions can also take any suitable form other than a recess or groove. For example, in an embodiment not shown, the first receiving portion 42 can be in the form of a pin or protrusion around which a coil spring is disposed; in this case, the second receiving portion 22 can be, for example, in the form of a recess or groove. Similarly, the second receiving portion 22 can be in the form of a pin or protrusion around which a coil spring is disposed; in this case, the first receiving portion 42 can be, for example, in the form of a recess or groove. Alternatively, both the first receiving portion 42 and the second receiving portion 22 can be in the form of pins or protrusions around which a coil spring is disposed.

[0097] In the illustrated embodiment, the second magnetically conductive member 40 has two abutting sections 44, correspondingly forming two first receiving portions 42, while the moving contact element 20 has correspondingly formed two second receiving portions 22. However, those skilled in the art will understand that the number of receiving portions matches the number of elastic elements 60 and can be selected according to the needs and design of the actual application to provide the desired elastic force.

[0098] The dimensions of the first receiving portion 42 and the second receiving portion 22, such as their depth and diameter, can be determined based on the parameters of the elastic element 60 (e.g., length and outer diameter) to ensure that an elastic element 60 (coil spring) of suitable size (e.g., length and outer diameter) can be used to obtain the desired compression size and elastic force, which is beneficial for adjusting the distance between the second magnetically conductive member 40 and the moving contact element 20. On the other hand, the reception of the elastic element 60 in the first receiving portion 42 and the second receiving portion 22 also prevents the elastic element 60 from shifting along the length direction (X direction) and the width direction (Y direction), which helps the normal operation of the elastic element 60, i.e., the compression and extension of the coil spring along the height direction (Z direction).

[0099] The receiving part can help adjust the distance between the second magnetic conductive member 40 and the moving contact element 20, and can also constrain the offset movement of the elastic element 60, which helps the elastic element 60 to operate normally.

[0100] According to some embodiments of this application, the second magnetic conductive member 40 is provided with a first receiving portion 42, and the elastic element 60 includes a spring body 62 and a deformable portion 64 extending from the spring body 62. The spring body 62 is fixed to the moving contact element 20, and the end of the deformable portion 64 is received at the first receiving portion 42.

[0101] like Figures 6 to 8 As shown, the elastic element 60 is in the form of a disc spring. The second magnetically conductive member 40 may be formed with an abutment section 44, on which the elastic element 60 may abut. A first receiving portion 42 for receiving the elastic element 60 may be formed on the abutment section 44, which may be, for example, in the form of a groove. Similarly, those skilled in the art will understand that the first receiving portion 42 may be any other suitable form besides a groove. For example, in an embodiment not shown, the first receiving portion 42 may be a slide rail or other guided sliding structure.

[0102] The elastic element 60 includes a spring body 62 and deformable portions 64 extending from the spring body 62. In the illustrated embodiment, two deformable portions 64 are shown, extending outward from opposite sides of the spring body 62. Those skilled in the art will understand that the number and shape of the deformable portions 64 can be selected and designed according to the needs of the actual application. With two deformable portions 64, the second magnetically conductive member 40 can correspondingly be provided with two first receiving portions 42, with the end of each deformable portion 64 receiving into a corresponding first receiving portion 42.

[0103] The size and shape of the first receiving portion 42 can be determined based on the size and shape of the deformable portion 64. The spring body 62 of the elastic element 60 can be fixed to the moving contact element 20 by various suitable methods such as threaded connection, riveting, pin connection, welding, etc. For example, in the illustrated embodiment, three mounting holes 202 are formed on the moving contact element 20, and correspondingly, three mounting holes 622 are formed on the spring body 62, thereby the spring body 62 can be fixed to the moving contact element 20 by means of bolts, rivets, pins, etc. passing through these mounting holes 202, 622. The elastic element 60 is located between the moving contact element 20 and the second magnetic conductive member 40. When the second magnetic conductive member 40 moves toward the moving contact element 20, the deformable portion 64 of the elastic element 60 elastically deforms accordingly to generate elastic force to bias the second magnetic conductive member 40, for example, biasing the second magnetic conductive member 40 toward its first position. During the elastic deformation of the deformable portion 64, the end of the deformable portion 64 can slide in the first receiving portion 42, for example, in the illustrated embodiment, it slides along the length direction in the first receiving portion 42. Thus, the first receiving portion 42 can serve as a guide and also prevent the deformable portion 64 from shifting.

[0104] Similarly, the spring body 62 is fixed to the moving contact element 20 and the first receiving part 42 guides and constrains the movement of the deformable part 64, which can facilitate the adjustment of the distance between the second magnetic conductive member 40 and the moving contact element 20, and help the normal operation of the elastic element 60.

[0105] According to some embodiments of this application, the second magnetic conductive member 40 can be formed as a U-shaped structure, and the moving contact element 20 can be arranged between the U-shaped structures such that when the second magnetic conductive member 40 moves toward the first magnetic conductive member 30, the second magnetic conductive member 40 can be guided along the edge of the moving contact element 20 and move relative to the moving contact element 20.

[0106] like Figure 3 and Figure 6As shown, the second magnetically conductive member 40 may include an abutting section 44 and protruding sections 46 extending in the height direction from opposite sides of the abutting section 44 in the width direction, thereby forming a U-shaped structure. The moving contact element 20 may be arranged between the U-shaped structures, i.e., between the two protruding sections 46 opposite each other in the width direction, facing the abutting section 44 in the height direction. When the stationary contact element 10 contacts the moving contact element 20, the second magnetically conductive member 40 continues to move towards the first magnetically conductive member 30, at which time the second magnetically conductive member 40 moves relative to the moving contact element 20 in the height direction. Since the moving contact element 20 is located between the two protruding sections 46, the second magnetically conductive member 40 can be guided to move in the height direction along the two opposite edges of the moving contact element 20 in the width direction, while the moving contact element 20 can prevent the second magnetically conductive member 40 from deviating in the width direction.

[0107] By forming the second magnetic conductive member 40 into a U-shaped structure and arranging the moving contact element 20 between the U-shaped structures, it is possible to guide the movement of the second magnetic conductive member 40 in the height direction and prevent the second magnetic conductive member 40 from deviating in the width direction.

[0108] According to some embodiments of this application, the relay 1 may further include a mounting bracket 70, which can be fixed to the moving contact element 20 to movably constrain the second magnetic conductive member 40 between the mounting bracket 70 and the moving contact element 20.

[0109] like Figures 3 to 8 As shown, the mounting bracket 70 is used to movably mount the second magnetically conductive member 40 onto the moving contact element 20. In some embodiments, the mounting bracket 70 can be fixed to the moving contact element 20 such that the mounting bracket 70 and the moving contact element 20 do not move relative to each other. The second magnetically conductive member 40 is arranged between the mounting bracket 70 and the moving contact element 20 and is movable relative to the mounting bracket 70 and the moving contact element 20 in the height direction, but can only move between the mounting bracket 70 and the moving contact element 20, and is constrained by the mounting bracket 70 and the moving contact element 20 and cannot move outside the mounting bracket 70 and the moving contact element 20.

[0110] The mounting bracket 70 can movably connect the second magnetic conductive component 40 to the moving contact element 20, and can also constrain the movement of the second magnetic conductive component 40, which helps to limit the range of movement of the second magnetic conductive component 40.

[0111] According to some embodiments of this application, the mounting bracket 70 may have a bracket body 72, which may be fixed to the moving contact element 20.

[0112] The bracket body 72 can be fixed to the moving contact element 20 by various suitable methods such as threaded connection, riveting, pin connection, welding, etc. For example, in the illustrated embodiment, three mounting holes 202 are formed on the moving contact element 20, and correspondingly, three mounting holes 724 are formed on the bracket body 72, so that the bracket body 72 can be fixed to the moving contact element 20 by means of bolts, rivets, pins, etc. passing through these mounting holes 202, 724.

[0113] When the elastic element 60 is a disc spring, such as Figures 6 to 8 As shown, three mounting holes 622 are formed on the spring body 62 of the elastic element 60, thereby allowing the spring body 62 to be fixed to the moving contact element 20 via bolts, rivets, pins, etc., passing through the mounting holes 202, 622. At this time, both the spring body 62 and the bracket body 72 are fixed to the moving contact element 20. For this purpose, bolts, rivets, pins, etc., can be used to fix the spring body 62 and the bracket body 72 to the moving contact element 20 via mounting holes 202, 622, 724. In the illustrated embodiment, the spring body 62 is located between the moving contact element 20 and the bracket body 72. In embodiments not shown, the bracket body 72 may be located between the moving contact element 20 and the spring body 62. Alternatively, any other suitable fixing arrangement can be used, for example, the spring body 62 and the bracket body 72 can be fixed to the moving contact element 20 side-by-side or integrally (i.e., the mounting bracket 70 and the elastic element 60 can be formed as a single structure).

[0114] According to some embodiments of this application, the two ends of the support body 72 may be formed with support sections 722 configured to support the second magnetic conductive member 40.

[0115] As shown in the figure, support sections 722 are formed at both ends of the bracket body 72. When the second magnetic conductive member 40 is arranged between the mounting bracket 70 and the moving contact element 20, the support sections 722 can be used to support the second magnetic conductive member 40.

[0116] According to some embodiments of this application, the second magnetic conductive member 40 may include two protruding segments 46, each of which may be formed in the form of a U-shape. The moving contact element 20 may be arranged between the two protruding segments 46, and the support segment 722 may be arranged between the two legs 462 of the corresponding protruding segment 46 and configured to support the connecting portion 464 of the corresponding protruding segment 46.

[0117] According to some embodiments of this application, the second magnetic conductive member 40 may include two abutting segments 44, each abutting segment 44 may be connected to a corresponding leg of each of the two protruding segments 46, such that the two abutting segments 44 and the two protruding segments 46 together form a U-shaped structure.

[0118] As shown in the figure, the second magnetically conductive member 40 may include two protruding segments 46 and two abutting segments 44, which are connected to each other to form an integral U-shaped structure. Specifically, the two abutting segments 44 may be arranged separately along the length direction, and the two protruding segments 46 are disposed between the two abutting segments 44 along the length direction and extend from the abutting segments 44 along the height direction, and the two protruding segments 46 are arranged opposite each other along the width direction. Each protruding segment 46 may be formed in the form of a U-shaped structure, including two legs 462 extending along the height direction and a connecting portion 464 extending along the length direction connecting the two legs 462. One leg 462 of one protruding segment 46 and one leg 462 of another protruding segment 46 are connected to one abutting segment 44, and the other leg 462 of one protruding segment 46 and the other leg 462 of another protruding segment 46 are connected to another abutting segment 44, thereby the two abutting segments 44 and the two protruding segments 46 together form a U-shaped structure. In this way, a space for accommodating the mounting bracket 70 is formed between the two abutting sections 44 and between the legs 462 of the two protruding sections 46, so that a very compact structure can be formed after the moving contact element 20, the second magnetic conductive member 40 and the mounting bracket 70 are assembled.

[0119] The moving contact element 20 can be arranged between the two protruding sections 46 to guide the movement of the second magnetically conductive member 40 in the height direction and prevent the second magnetically conductive member 40 from shifting in the width direction. Support sections 722 can be located at both ends of the bracket body 72 in the width direction, such that the support sections 722 can be respectively arranged between the two legs 462 of the corresponding protruding sections 46; that is, one support section 722 is arranged between the two legs 462 of one protruding section 46, and the other support section 722 is arranged between the two legs 462 of the other protruding section 46. In this way, the two support sections 722 can respectively support the connecting portion 464 of the two protruding sections 46, thereby enabling the mounting bracket 70 to support the second magnetically conductive mechanism 40 and prevent the second magnetically conductive member 40 from dislodging from between the moving contact element 20 and the mounting bracket 70. Meanwhile, since the support section 722 is located between the legs 462 of the protruding section 46, it can also prevent the second magnetic conductive member 40 from shifting along the length direction, and guide the second magnetic conductive member 40 to move along the height direction.

[0120] This arrangement of the second magnetic conductive member 40 and the mounting bracket 70 not only achieves a compact structure, supporting and constraining the second magnetic conductive member 40, but also guides the movement of the second magnetic conductive member 40 along the height direction and prevents the second magnetic conductive member 40 from deviating along the length direction.

[0121] According to some embodiments of this application, the mounting bracket 70 may have a bracket section 74 extending from the bracket body 72, the second magnetic member 40 may include an abutment section 44, and the bracket section 74 may be configured to support the abutment section 44 and / or guide the movement of the abutment section 44.

[0122] According to some embodiments of this application, the second magnetic conductive member 40 may include two abutting sections 44, and the mounting bracket 70 may correspondingly have two bracket sections 74 extending from opposite sides of the bracket body 72.

[0123] As shown in the figure, the mounting bracket 70 may include two bracket segments 74 extending approximately in the height direction from opposite sides of the bracket body 72 along the length direction. The number, size, and shape of the bracket segments 74 extending from the bracket body 72 can be selected according to the actual application requirements, for example, to adapt to the size and shape of the abutment segment 44. The bracket segments 74 extend through the space between the two abutment segments 44 and between the legs 462 of the two protruding segments 46 to the underside of the abutment segments 44, thereby supporting the abutment segments 44 in the height direction and preventing the second magnetic member 40 from disengaging from between the driven contact element 20 and the mounting bracket 70.

[0124] When the support section 74 extends approximately along the height direction, the support section 74 can also serve as a guide. When the second magnetic conductive member 20 moves relative to the moving contact element 20 along the height direction, the abutting section 44 can be guided to move along the support section 74. At the same time, the support section 74 can also prevent the abutting section 44 from shifting along the length direction.

[0125] According to some embodiments of this application, the support segment 74 may include a guide portion 742 extending from the support body 72 and a support portion 744 extending from the end of the guide portion 742 opposite to the support body 72. The guide portion 742 cooperates with the abutment segment 44 to guide the movement of the abutment segment 44, and the support portion 744 is configured to support the abutment segment 44.

[0126] As shown in the figure, the guide portion 742 can extend from the bracket body 72 along the height direction, so that when the second magnetic member 40 moves relative to the moving contact element 20, the abutment section 44 of the second magnetic member 40 can move along the guide portion 742 to be guided to move along the height direction, while preventing the abutment section 44 from shifting along the length direction. The support portion 744 can extend below the abutment section 44, thereby supporting the abutment section 44 along the height direction and preventing the second magnetic member 40 from dislodging from between the moving contact element 20 and the mounting bracket 70.

[0127] According to some embodiments of this application, a protrusion 48 may be provided on the abutting section 44, and a guide recess 746 may be formed on the supporting section 744. The guide recess 746 cooperates with the protrusion 48 to guide the movement of the protrusion 48.

[0128] like Figures 3 to 5 As shown, a protrusion 48 may be formed below the abutment section 44. This protrusion 48 may be, for example, in the form of a cylindrical protrusion, extending from the abutment section 44 along the height direction. A guide recess 746 may be formed at the end of the support portion 744 opposite to the guide portion 742. The contour of the guide recess 746 may match the shape of the protrusion 48 so that when the second magnetic member 40 moves relative to the moving contact element 20, the guide recess 746 cooperates with the protrusion 48 to guide the movement of the protrusion 48 along the height direction.

[0129] The relay according to this application employs a floating magnetic conductive structure to adjust the distance between the magnetic conductive components, thereby adjusting the attractive force between them. Furthermore, by setting the magnetic conductive component associated with the moving contact element as a floating magnetic conductive component, not only can the distance be adjusted, but the elastic force of the elastic element can also be fully utilized to additionally promote contact between the stationary and moving contact elements. Moreover, the assembly of the moving contact element, mounting bracket, and magnetic conductive component forms a compact structure, fully utilizing the shape fit between the components, saving space and obtaining additional guiding and restraining effects.
