Description

Technical Field

[0001] This application generally relates to a relay whose magnetic structure can be stably connected to a moving contact element. 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 circuit 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, the lower magnetic block usually moves with the moving contact. In this case, the assembly, fixing and support between the lower magnetic block and the moving contact are issues that need to be considered. 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 that can provide a robust connection between a magnetically conductive component and a moving contact element.

[0006] Another objective of this application is to provide a relay that can achieve a compact design while also providing constraint functions.

[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 relay further includes a mounting bracket fixed to the moving contact element to securely constrain the second magnetic conductive member between the mounting bracket and the moving contact element.

[0013] The mounting bracket can both fix the second magnetic component to the moving contact element and constrain its movement, thus helping to maintain its stability and preventing it from moving relative to the moving contact element during its vertical movement, such as swaying or swinging.

[0014] In some embodiments of the relay, the second magnetic conductive member is provided with a protrusion, and the moving contact element is provided with a corresponding receiving portion, wherein the protrusion on the second magnetic conductive member is received in the receiving portion on the moving contact element, and / or the second magnetic conductive member is provided with a receiving portion, and the moving contact element is provided with a corresponding protrusion, wherein the protrusion on the moving contact element is received in the receiving portion on the second magnetic conductive member.

[0015] The protrusion and receiving portion prevent the second magnetic conductor from moving relative to the moving contact element in the length and width directions.

[0016] In some embodiments of the relay, the second magnetic conductive member is formed into a U-shaped structure, and the moving contact element is arranged between the U-shaped structures.

[0017] 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 prevent the second magnetic conductive member from shifting along the width direction.

[0018] In some embodiments of the relay, the mounting bracket has a bracket body that is fixed to the moving contact element.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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 prevents the second magnetic conductive component from shifting along its length.

[0023] 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.

[0024] 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.

[0025] 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 support portion being configured to support the abutment section.

[0026] The relay according to this application supports and fixes the magnetic conductive component to the moving contact element using a mounting bracket, ensuring that the magnetic conductive component does not move relative to the moving contact element during its movement. Furthermore, 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 providing additional constraint.

[0045] 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.

[0047] 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.

[0048] 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.”

[0049] 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.

[0051] 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 circuit 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.

[0052] However, the lower magnetic block usually moves with the moving contact. In this case, the assembly, fixing and support between the lower magnetic block and the moving contact are issues that need to be considered.

[0053] refer to Figures 1 to 3 , Figure 1 A cross-sectional view of a relay 1 according to some embodiments of this application is shown. Figure 2 and Figure 3 Cross-sectional perspective views and exploded perspective views of relays according to some embodiments of this application are shown, with some components removed to show the internal structure of the relay. 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.

[0054] 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).

[0055] 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 leads of the stationary contact elements 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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 mounting bracket for supporting and securing a magnetically conductive member to a moving contact element.

[0060] 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 relay 1 may further include a mounting bracket 70 fixed to the moving contact element 20 to securely restrain the second magnetically conductive member 40 between the mounting bracket 70 and the moving contact element 20.

[0061] As mentioned above, refer to Figure 1 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.

[0062] According to an embodiment of this application, the relay 1 may further include a mounting bracket 70, which can be fixed to the moving contact element 20 to fix the second magnetic conductive member 40 between the mounting bracket 70 and the moving contact element 20.

[0063] like Figures 4 to 7 As shown, the mounting bracket 70 is used to fix the second magnetic conductive member 40 to the moving contact element 20, wherein... Figures 4 to 7 The diagram shows an assembly schematic, exploded perspective view, front view, and sectional front view of the moving contact element 20, the second magnetic conductive member 40, and the mounting bracket 70. In some embodiments, the mounting bracket 70 can be fixed to the moving contact element 20 so that the mounting bracket 70 and the moving contact element 20 do not move relative to each other. The second magnetic conductive member 40 is arranged 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, thus preventing it from moving relative to the mounting bracket 70 and the moving contact element 20.

[0064] The mounting bracket 70 can fix 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 maintain the stability of the second magnetic conductive component 40 and prevents the second magnetic conductive component 40 from moving relative to the moving contact element 20 during the movement of the moving contact element 20 in the height direction, such as shaking or swinging.

[0065] According to some embodiments of this application, a protrusion 42 may be provided on the second magnetic conductive member 40, and a corresponding receiving portion 22 may be provided on the moving contact element 20. The protrusion 42 on the second magnetic conductive member 40 may be received in the receiving portion 22 on the moving contact element 20, and / or the second magnetic conductive member 40 may be provided with a receiving portion, and the moving contact element 20 may be provided with a corresponding protrusion. The protrusion on the moving contact element 20 may be received in the receiving portion on the second magnetic conductive member 40.

[0066] like Figure 5 and Figure 7 The illustration shows an embodiment where a protrusion 42 is provided on the second magnetically conductive member 40 and a corresponding receiving portion 22 is provided on the moving contact element 20. The second magnetically conductive member 40 may have an abutting section 44, on which the protrusion 42 may be formed. The protrusion 42 may, for example, be a structure that protrudes upwards from the abutting section 44 in the height direction. A receiving portion 22 may be formed on the moving contact element 20 at a position corresponding to the protrusion 42. This receiving portion 22 may be, for example, in the form of a recess or groove, into which the protrusion 42 of the second magnetically conductive member 40 can be received.

[0067] In some embodiments, a receiving portion may be formed on the second magnetically conductive member 40, while a protrusion may be formed on the moving contact element 20. For example, a receiving portion in the form of a recess or groove may be formed on the abutting section 44 of the second magnetically conductive member 40, and a protrusion extending toward the moving contact element 20 in the height direction may be formed at a position on the moving contact element 20 corresponding to the receiving portion, the protrusion being received in the receiving portion. Alternatively, in other embodiments, a protrusion and a receiving portion may be formed on the second magnetically conductive member 40, while a corresponding receiving portion and a protrusion may be formed on the moving contact element 20, such that the protrusion on the second magnetically conductive member 40 is received in the receiving portion on the moving contact element 20, and the protrusion on the moving contact element 20 is received in the receiving portion on the second magnetically conductive member 40.

[0068] In the illustrated embodiment, the second magnetically conductive member 40 has two abutting sections 44, correspondingly forming two protrusions 42, while two receiving portions 22 are correspondingly formed on the moving contact element 20. However, those skilled in the art will understand that the number of receiving portions matches the number of protrusions 42, and can be selected according to the needs and design of the actual application, in order to provide the desired movement restriction in the length and width directions.

[0069] The dimensions of the protrusion 42 and the receiving portion 22, such as their depth and diameter, can be determined according to the design requirements of the relay to ensure that the second magnetic component 40 cannot move relative to the moving contact element 20 in the length and width directions.

[0070] The protrusion and the receiving portion prevent the second magnetic conductor 40 from moving relative to the moving contact element 20 in the length and width directions.

[0071] 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.

[0072] like Figures 2 to 7 As shown, the second magnetically conductive member 40 may include an abutment section 44 and protruding sections 46 extending in the height direction from opposite sides of the abutment 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 abutment section 44 in the height direction. When the stationary contact element 10 contacts the moving contact element 20, since the moving contact element 20 is located between the two protruding sections 46, the two protruding sections 46 of the second magnetically conductive member 40 prevent the moving contact element 20 from shifting in the width direction.

[0073] 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 prevent the second magnetic conductive member 40 from shifting along the width direction.

[0074] 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.

[0075] The bracket body 72 can be secured to the moving contact element 20 by fasteners 60, such as threaded connections, riveting, pin connections, welding, etc. For example, in some embodiments, such as Figure 5 As shown, 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, thereby allowing the bracket body 72 to be fixed to the moving contact element 20 by means of fasteners 60 such as bolts, rivets, pins, etc. passing through these mounting holes 202 and 724.

[0076] In other embodiments, such as Figure 8 As shown, a fastening protrusion 62 can be formed on the side of the moving contact element 20 facing downward along the height direction. Correspondingly, a mounting hole 724 can be formed on the bracket body 72. Thus, the fastening protrusion 62 passes through the mounting hole 724 to fix the bracket body 72 to the moving contact element 20.

[0077] 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.

[0078] like Figure 5 As shown, 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.

[0079] 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.

[0080] 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.

[0081] like Figure 5 As shown, 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 disposed 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.

[0082] The moving contact element 20 can be arranged between the two protruding sections 46 to prevent the second magnetically conductive member 40 from shifting along its width. Support sections 722 can be located at both ends of the bracket body 72 along its width, 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. Simultaneously, since the support sections 722 are located between the legs 462 of the protruding sections 46, they also prevent the second magnetically conductive member 40 from shifting along its length.

[0083] 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 prevents the second magnetic conductive member 40 from shifting along its length.

[0084] According to some embodiments of this application, the mounting bracket 70 may have a bracket section 74 extending from the bracket body 72, and the second magnetic member 40 may include an abutment section 44, the bracket section 74 being configured to support the abutment section 44.

[0085] 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.

[0086] 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.

[0087] When the support section 74 extends approximately along the height direction, the support section 74 can also prevent the abutment section 44 from shifting along the length direction.

[0088] 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 support portion 744 being configured to support the abutment segment 44.

[0089] As shown in the figure, the guide portion 742 can extend from the bracket body 72 along the height direction, thereby 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 conductor 40 from dislodging from the driven contact element 20 and the mounting bracket 70.

[0090] The relay according to this application supports and fixes the magnetic conductive component to the moving contact element using a mounting bracket, ensuring that the magnetic conductive component does not move relative to the moving contact element during its movement. Furthermore, 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 providing additional constraint.

[0091] While exemplary embodiments of this application have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this application without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this application as defined by the claims. This application is defined by the appended claims, and equivalents of those claims are also included.
