Description

Technical Field

[0001] This application generally relates to a relay having a structure capable of constraining the oscillation of a moving contact. 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 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 moving contact may swing during movement, affecting the normal operation of the relay. 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 restrain the swinging of the moving contact unit.

[0006] According to a first aspect of this application, a relay is provided, comprising:

[0007] A housing that defines a contact chamber and has an inner wall;

[0008] A stationary contact unit that extends into the contact chamber;

[0009] A moving contact unit configured to move toward the stationary contact unit during operation, such that the moving contact unit contacts the stationary contact unit to achieve circuit continuity; and

[0010] An anti-sway mechanism is connected to the moving contact unit. The anti-sway mechanism has an anti-sway member that defines an anti-sway gap between itself and the inner wall of the housing. The anti-sway mechanism is configured to restrain the swaying of the moving contact unit by the anti-sway member abutting against the inner wall of the housing when the moving contact unit sways.

[0011] An anti-sway gap exists between the anti-sway component and the inner wall of the housing. This gap does not affect the normal operation of the moving contact unit and does not hinder its movement along the height direction. However, if the moving contact unit does sway, the anti-sway component of the anti-sway mechanism can abut against the inner wall of the housing to restrain the swaying motion of the moving contact unit. Furthermore, directly utilizing the inner wall of the housing as a constraint structure eliminates the need for additional components to restrain the swaying of the moving contact unit, saving costs and reducing structural complexity.

[0012] In some embodiments of the relay, the anti-sway mechanism includes an anti-sway body, and the anti-sway member extends from the edge of the anti-sway body toward the inner wall of the housing.

[0013] In some embodiments of the relay, the anti-sway member is in the form of a protrusion extending toward the inner wall of the housing in a direction perpendicular to the inner wall of the housing.

[0014] The anti-sway component is formed to extend toward the inner wall of the shell in a vertical orientation, which simplifies the structure and saves costs.

[0015] In some embodiments of the relay, the anti-sway member includes a first segment having a curved shape and a second segment having a straight shape, wherein an abutment portion is provided on the second segment, and the abutment portion defines the anti-sway gap between itself and the inner wall of the housing.

[0016] The curved first section and the straight second section together provide a certain degree of flexibility to the anti-sway member, allowing it to undergo elastic deformation when it abuts against the inner wall of the shell, thus buffering the impact generated by this contact. Simultaneously, the abutting portion on the second section reduces the interaction between the anti-sway member and the inner wall of the shell.

[0017] In some embodiments of the relay, the anti-sway member includes a first anti-sway member and a second anti-sway member, wherein the first anti-sway member defines a first anti-sway gap with the inner wall of the housing, and the second anti-sway member defines a second anti-sway gap with the inner wall of the housing, wherein the first anti-sway gap is smaller than the second anti-sway gap.

[0018] By employing different anti-sway gaps, a trade-off can be struck between influencing the movement of the moving contact unit and constraining its swaying motion, resulting in a more balanced effect.

[0019] In some embodiments of the relay, the anti-sway mechanism is provided on opposite sides of the moving contact unit, such that the anti-sway member forms the anti-sway gap with the corresponding inner wall on opposite sides of the housing.

[0020] Setting anti-sway mechanisms on opposite sides of the moving contact unit can simplify the structure while providing a more comprehensive constraint on the swaying motion of the moving contact unit.

[0021] In some embodiments of the relay, the anti-sway mechanism includes a plurality of the anti-sway components arranged symmetrically around the moving contact unit.

[0022] In some embodiments of the relay, the relay further includes an actuating component coupled to and configured to actuate the moving contact unit, the actuating component having a base on which the anti-sway mechanism is disposed.

[0023] In some embodiments of the relay, the anti-sway mechanism includes a first bracket and a second bracket extending from opposite sides of the base, respectively, the anti-sway member extending accordingly from the first bracket and the second bracket toward the inner wall of the housing, and the moving contact unit being sandwiched between the first bracket and the second bracket.

[0024] The support structure extending upwards from the base is usually an existing structure in the relay, so using it as part of the anti-sway mechanism can simplify the structure, reduce the difficulty of processing, save costs, and does not require major modifications to the existing relay structure.

[0025] In some embodiments of the relay, reinforcing ribs are formed on the inner wall of the housing, and the anti-swaying component of the anti-swaying mechanism is positioned close to the reinforcing ribs.

[0026] The anti-sway component is positioned close to the reinforcing rib, which can provide a favorable restraining effect and prevent swaying motion from damaging the shell.

[0027] The anti-sway mechanism of the relay according to this application can prevent the movement of the moving contact unit from affecting the normal operation of the relay, and can restrain the swaying movement of the moving contact unit when swaying occurs. At the same time, the anti-sway mechanism of the relay according to this application does not require major modifications to the structure of existing relays, and can significantly reduce production costs.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.”

[0047] 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. In the specification, the description of a feature being arranged "adjacent" to another feature can mean that a feature has a portion overlapping with the adjacent feature or a portion located above or below the adjacent feature.

It should be understood that spatial relation terms include not only the orientation shown in the drawings but also the different orientations of the device during use or operation. For example, when the device in the drawings is inverted, a feature previously described as "below" other features can now be described as "above" other features. 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.

[0049] 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.

[0050] 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.

[0051] refer to Figure 1 and Figure 2 , Figure 1 A front view of a relay 1 according to some embodiments of this application is shown. Figure 2 A 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.

[0052] The relay 1 may include a stationary contact unit 10 and a moving contact unit 20. The stationary contact unit 10 extends into a contact chamber 12 formed by the housing 11, and the moving contact unit 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).

[0053] During the operation of relay 1, the moving contact unit 20 moves along the height direction toward the stationary contact unit 10 to make contact with the stationary contact unit 10 within the contact chamber 12, thereby achieving circuit conduction. In the illustrated embodiment, the stationary contact unit 10 of relay 1 is shown to have two stationary contact elements 102, and the moving contact unit 20 has one moving contact element 202 and a magnetic block 204. The lead-out end of the stationary contact element 102 of the stationary contact unit 10 is used to contact the moving contact element 202 of the moving contact unit 20. Those skilled in the art will understand that other suitable forms and numbers of stationary contact elements 102 and moving contact elements 202 can also be used as needed. The stationary contact unit 10 and the moving contact unit 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.

[0054] Typically, the relay 1 may also include a push assembly 50 configured to push the moving contact unit 20 toward the stationary contact unit 10 along the height direction to contact the stationary contact unit 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 unit 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 unit 20 along the height direction via the spring 56. When the moving contact element 202 of the moving contact unit 20 contacts the stationary contact element 102 of the stationary contact unit 10, the moving contact unit 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 202 of the moving contact unit 20 and the stationary contact element 102 of the stationary contact unit 10.

[0055] When the moving contact element 202 of the moving contact unit 20 contacts the stationary contact element 102 of the stationary contact unit 10, the circuit is turned on, and current flows through both the moving contact element 202 and the stationary contact element 102. At this time, a repulsive force may be generated between the moving contact element 202 and the stationary contact element 102, tending to separate them and disengage. This repulsive force may exceed the pushing force of the pushing component 50 on the moving contact unit 20, ultimately causing the moving contact element 202 of the moving contact unit 20 to separate from the stationary contact element 102 of the stationary contact unit 10. In this case, to ensure contact between the moving contact element 202 of the actuating contact unit 20 and the stationary contact element 102 of the stationary contact unit 10, a magnetically conductive member can be provided to prevent separation between the moving contact element 202 of the moving contact unit 20 and the stationary contact element 102 of the stationary contact unit 10. Specifically, for example, in Figure 2 In the illustrated embodiment, the moving contact unit 20 of the relay 1 may include a magnetically conductive member 204. When the moving contact element 202 of the moving contact unit 20 contacts the stationary contact element 102 of the stationary contact unit 10, the magnetically conductive member 204 forms a magnetically conductive circuit to generate an attractive force, thereby enhancing and maintaining the contact between the moving contact element 202 of the moving contact unit 20 and the stationary contact element 102 of the stationary contact unit 10.

[0056] 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.

[0057] The following will be referenced Figures 1 to 8 The present application describes in detail a relay 1 according to some embodiments, which includes an anti-sway mechanism 30 for restraining the swaying motion of a moving contact unit 20.

[0058] According to some embodiments of this application, a relay 1 is provided, which may include: a housing 11 defining a contact chamber 12 and having an inner wall 112; a stationary contact unit 10 extending into the contact chamber 12; a moving contact unit 20 configured to move toward the stationary contact unit 10 during operation, such that the moving contact unit 20 contacts the stationary contact unit 10 to achieve circuit conduction; and an anti-sway mechanism 30 connected to the moving contact unit 20, the anti-sway mechanism 30 having an anti-sway member 34, the anti-sway member 34 defining an anti-sway gap with the inner wall 112 of the housing 11, the anti-sway mechanism 30 being configured to restrain the swaying of the moving contact unit 20 by the anti-sway member 34 abutting against the inner wall 112 of the housing 11 when the moving contact unit 20 sways.

[0059] like Figure 1 and Figure 2 As shown, the housing 11 has a contact chamber 12 in which the stationary contact unit 10 and the moving contact unit 20 can be accommodated. The stationary contact element 102 of the stationary contact unit 10 and the moving contact element 202 of the moving contact unit 20 perform contact operations within the contact chamber 12. The inner wall 112 of the housing 11 at least surrounds and faces the moving contact unit 20.

[0060] When the moving contact unit 20 moves toward the stationary contact unit 10 under the drive of the pushing component 50, the moving contact unit 20 may oscillate, including, for example, rotating or shaking. This oscillation may adversely affect the vertical movement of the moving contact unit 20, hindering the contact between the moving contact element 202 of the moving contact unit 20 and the stationary contact element 102 of the stationary contact unit 10. This could potentially cause the relay 1 to malfunction, affecting its operational performance.

[0061] Therefore, according to an embodiment of this application, the relay 1 is provided with an anti-sway mechanism 30 to restrain the swaying motion of the moving contact unit 20 during operation. (See reference...) Figures 3 to 8 As shown, Figure 3 This is a partial cross-sectional perspective view of a relay 1 according to some embodiments of this application; Figure 4 This is a perspective view of the push assembly 50 and the anti-sway mechanism 30 of the relay 1 according to some embodiments of this application; Figure 5 This is a top cross-sectional view of a relay 1 according to some embodiments of this application; Figure 6 This is a partial cross-sectional perspective view of relay 1 according to other embodiments of this application; Figure 7 This is a perspective view of the push assembly 50 and the anti-sway mechanism 30 of the relay 1 according to other embodiments of this application; Figure 8 This is a top cross-sectional view of relay 1 according to other embodiments of this application.

[0062] The anti-sway mechanism 30 is connected to the moving contact unit 20, enabling the anti-sway mechanism 30 to move together with the moving contact unit 20. That is, during operation, the anti-sway mechanism 30 moves together with the moving contact unit 20 in the height direction. Therefore, when the moving contact unit 20 sways, the anti-sway mechanism 30 also sways accordingly.

[0063] The anti-sway mechanism 30 may have an anti-sway member 34, which may be disposed close to the inner wall 112 of the housing 11 to define an anti-sway gap between itself and the inner wall 112 of the housing 11. The presence of the anti-sway gap ensures that the anti-sway member 34 does not contact the inner wall 112 of the housing 11 under normal conditions, and consequently, the anti-sway mechanism 30 does not contact the inner wall 112 of the housing 11.

[0064] The anti-sway mechanism 30 can be configured to restrain the swaying of the moving contact unit 20 by the anti-sway member 34 abutting against the inner wall 112 of the housing 11 when the moving contact unit 20 sways. When the moving contact unit 20 sways during operation, the anti-sway mechanism 30 also sways, causing the anti-sway gap between the anti-sway member 34 and the inner wall 112 of the housing 11 to change. When the swaying amplitude of the moving contact unit 20 and the anti-sway mechanism 30 reaches a certain level, the anti-sway member 34 of the anti-sway mechanism 30 will contact the inner wall 112 of the housing 11, that is, the anti-sway member 34 abuts against the inner wall 112 of the housing 11. When the anti-sway member 34 abuts against the inner wall 112 of the housing 11, the inner wall 112 blocks the anti-sway member 34 to resist further swaying movement of the anti-sway member 34, so that the anti-sway member 34 cannot make a larger swaying movement, that is, the swaying of the anti-sway member 34 is constrained, thereby constraining the swaying of the anti-sway mechanism 30 and the moving contact unit 20.

[0065] The anti-sway mechanism 30 may be provided with multiple anti-sway components 34, which may be arranged around the moving contact unit 20 to constrain the swaying of the moving contact unit 20 from different positions.

[0066] An anti-sway gap exists between the anti-sway member 34 and the inner wall 112 of the housing 11. This gap does not affect the normal operation of the moving contact unit 20 and does not hinder its movement along the height direction. However, if the moving contact unit 20 sways, the anti-sway member 34 of the anti-sway mechanism 34 can abut against the inner wall 112 of the housing 11 to restrain the swaying motion of the moving contact unit 20. On the other hand, by directly using the inner wall 112 of the housing 11 as a constraint structure, additional components used to restrain the swaying of the moving contact unit 20 can be omitted, saving costs and reducing structural complexity.

[0067] According to some embodiments of this application, the anti-sway mechanism 30 may include an anti-sway body 32, and an anti-sway member 34 may extend from the edge of the anti-sway body 32 toward the inner wall 112 of the housing 11.

[0068] like Figures 3 to 8 As shown, the anti-sway mechanism 30 may include an anti-sway body 32, which is connected to the moving contact unit 20 so that the anti-sway mechanism 30 can move together with the moving contact unit 20. The anti-sway body 32 may be, for example, a sheet-like structure, connected to the moving contact unit 20 from the side, and may extend substantially parallel to the inner wall 112 of the housing 11 to reduce the space it occupies.

[0069] The distance between the anti-sway body 32 and the inner wall 112 of the housing 11 can be relatively large to prevent the anti-sway body 32 from contacting the inner wall 112 of the housing 11. The anti-sway member 34 can extend from the anti-sway body 32 toward the inner wall 112 of the housing 11 to form an anti-sway gap between the anti-sway member 34 and the inner wall 112 of the housing 11, which is smaller than the distance between the anti-sway body 32 and the inner wall 112 of the housing 11. In the illustrated embodiment, the anti-sway member 34 extends from the vertical edge of the anti-sway body 32 toward the inner wall 112 of the housing 11, but it is understood that the anti-sway member 34 can extend from any position of the anti-sway body 32 toward the inner wall 112 of the housing 11, and is not limited to the illustrated embodiment.

[0070] According to some embodiments of this application, the anti-sway member 34 may be in the form of a protrusion extending toward the inner wall 112 in a direction perpendicular to the inner wall 112 of the housing 11.

[0071] like Figures 3 to 5 As shown, the anti-sway member 34 is shown in the form of a protrusion, for example, it can be a structure that protrudes from the anti-sway body 32 toward the inner wall 112 of the housing 11. Figure 4 As shown, the anti-sway member 34 can protrude from the vertical edges on both sides of the anti-sway body 32. However, it should be understood that the illustrated embodiment is merely exemplary, and the anti-sway member 34 can be designed to protrude from any suitable position of the anti-sway body 32 according to the needs of the actual application, such as from the top edge or the bottom edge.

[0072] The anti-sway member 34 can extend toward the inner wall 112 of the housing 11 in a direction perpendicular to the inner wall 112. For example... Figure 5As shown, the anti-sway member 34 extends from the anti-sway body 32 toward the inner wall 112 of the housing 11 in a direction perpendicular to the inner wall 112, thereby defining an anti-sway gap between the anti-sway member 34 and the inner wall 112 of the housing 11, i.e., the anti-sway member 34 does not directly contact the inner wall 112 of the housing 11. In the illustrated embodiment, four anti-sway members 34 are shown, but it should be understood that the number of anti-sway members 34 is not limited to this, but any suitable number can be selected according to the needs of the actual application.

[0073] The anti-sway member 34 is formed to extend toward the inner wall 112 of the housing 11 in a vertical orientation, which simplifies the structure and saves costs.

[0074] According to some embodiments of this application, the anti-sway member 34 may include a first segment 342 having a curved shape and a second segment 344 having a straight shape. An abutment portion 346 may be provided on the second segment 344, and an anti-sway gap is defined between the abutment portion 346 and the inner wall 112 of the housing 11.

[0075] like Figures 6 to 8 As shown, the anti-sway member 34 can be suspended from the anti-sway body 32. In the illustrated embodiment, the anti-sway member 34 is suspended from approximately the middle of the vertical edge of the anti-sway body 32, but this is merely exemplary and the anti-sway member 34 can be suspended from any suitable position of the anti-sway body 32.

[0076] The anti-sway member 34 may include a first segment 342 and a second segment 344. The first segment 342 is coupled to or integral with the anti-sway body 32. The first segment 342 may have a curved shape, such as an arc shape or a quarter-circle shape, such that one end of the first segment 342 extends from the anti-sway body 32 in a vertical orientation, and the other end extends in an orientation parallel to the anti-sway body 32. The second segment 344 extends from the first segment 342, for example, in a straight shape. In the illustrated embodiment, the second segment 344 extends in an orientation generally parallel to the anti-sway body 32 and the inner wall 112, but it should be understood that the second segment 344 may also extend in any suitable orientation.

[0077] In some embodiments, when the second segment 344 extends toward the inner wall 112 of the housing 11 in an inclined orientation, the free end of the second segment 344 may define the aforementioned anti-sway gap with the inner wall 112, and when the moving contact unit sways, the free end of the second segment 344 abuts against the inner wall 112 of the housing 11 to constrain the swaying motion of the moving contact unit 20.

[0078] In the illustrated embodiment, an abutment portion 346 may be provided on the second section 344. The abutment portion 346 defines an anti-swaying gap with the inner wall 112 of the housing 11, and when the moving contact unit sways, the abutment portion 346 on the second section 344 abuts against the inner wall 112 of the housing 11 to restrain the swaying movement of the moving contact unit 20. The abutment portion 346 may be in the form of a circular protrusion on the second section 344.

[0079] The curved first segment 342 and the straight second segment 344 together provide a certain degree of flexibility to the anti-sway member 34, allowing it to undergo elastic deformation when it abuts against the inner wall 112 of the housing 11, thus buffering the impact generated by this contact. At the same time, the abutting portion 346 on the second segment 344 can reduce the interaction between the anti-sway member 34 and the inner wall 112 of the housing 11.

[0080] According to some embodiments of this application, the anti-sway member 34 may include a first anti-sway member 340 and a second anti-sway member 341. A first anti-sway gap may be defined between the first anti-sway member 340 and the inner wall 112 of the housing 11, and a second anti-sway gap may be defined between the second anti-sway member 341 and the inner wall 112 of the housing 11. The first anti-sway gap may be smaller than the second anti-sway gap.

[0081] In some embodiments, the anti-sway mechanism 30 may have a plurality of anti-sway members 34 having the same construction, such that each anti-sway member 34 defines a substantially identical anti-sway gap with the inner wall 112 of the housing 11, thereby each anti-sway member 34 functions substantially equivalently, such as Figure 8 As shown.

[0082] like Figure 5 As shown in the illustrated embodiment, the anti-sway mechanism 30 may have multiple anti-sway members 34 with different structures. For example, a first anti-sway gap may be defined between the first anti-sway member 340 and the inner wall 112 of the housing 11, and a second anti-sway gap may be defined between the second anti-sway member 341 and the inner wall 112 of the housing 11. The first anti-sway gap may be smaller than the second anti-sway gap. That is, the distance that the first anti-sway member 340 extends toward the inner wall 112 of the housing 11 is longer than the distance that the second anti-sway member 341 extends toward the inner wall 112 of the housing 11, so that the first anti-sway member 340 is closer to the inner wall 112 of the housing 11 than the second anti-sway member 341.

[0083] The first anti-sway member 340 and the second anti-sway member 341 can be arranged alternately around the moving contact unit 20, such as... Figure 5As shown, other suitable arrangements can also be adopted. For example, the first anti-sway member 340 can be arranged on one side of the moving contact unit 20, while the second anti-sway member 341 can be arranged on the other side of the moving contact unit 20.

[0084] The first anti-sway member 340 defines a smaller first anti-sway gap, and the second anti-sway member 341 defines a larger second anti-sway gap, so that the first anti-sway member 340 can be used as a primary anti-sway member, and the second anti-sway member 341 can be used as a secondary anti-sway member. That is, when the moving contact unit 20 swings, the first anti-sway member 340 can first abut against the inner wall 112 of the housing 11 to restrain the swinging motion of the moving contact unit 20. If the swinging motion of the moving contact unit 20 is more violent, the first anti-sway member 340 may not be enough to restrain the swinging motion of the moving contact unit 20. In this case, the second anti-sway member 341 can abut against the inner wall 112 of the housing 11 to further restrain the swinging motion of the moving contact unit 20.

[0085] When the anti-sway gap is too small, the anti-sway component can easily touch the inner wall of the housing 11, affecting the movement of the moving contact unit 20 along the height direction. When the anti-sway gap is too large, the anti-sway component can only function when the swinging amplitude of the moving contact unit 20 is large, thus the anti-sway effect is poor. By using different anti-sway gaps, a compromise can be made between affecting the movement of the moving contact unit 20 and restraining its swinging motion, achieving a more balanced effect.

[0086] According to some embodiments of this application, anti-sway mechanisms 30 can be provided on opposite sides of the moving contact unit 20, so that the anti-sway members 34 can form anti-sway gaps with the corresponding inner walls 112 on opposite sides of the housing 11.

[0087] like Figures 3 to 8 As shown in the illustrated embodiment, anti-sway mechanisms 30 extending along the length direction are provided on both sides of the moving contact unit 20 along the width direction, so that the anti-sway members 34 can respectively form anti-sway gaps with the corresponding inner walls 112 on both sides of the housing 11 opposite in the width direction. Of course, it is understood that the illustrated embodiment is merely exemplary, and the anti-sway mechanism 30 can also adopt other suitable arrangements. For example, anti-sway mechanisms 30 extending along the width direction can be provided on both sides of the moving contact unit 20 along the length direction, so that the anti-sway members 34 can respectively form anti-sway gaps with the corresponding inner walls 112 on both sides of the housing 11 opposite in the length direction.

[0088] Setting anti-sway mechanisms 30 on opposite sides of the moving contact unit 20 can provide a more comprehensive constraint on the swaying motion of the moving contact unit 20 while simplifying the structure.

[0089] According to some embodiments of this application, the anti-sway mechanism 30 may include a plurality of anti-sway members 34, which may be arranged symmetrically around the moving contact unit 20.

[0090] As mentioned above, such as Figures 3 to 8 As shown, the anti-sway mechanism 30 may include multiple anti-sway members 34, such as the four anti-sway members 34 shown in the figure, or more or fewer than four anti-sway members 34 in other embodiments. These anti-sway members 34 may be arranged symmetrically around the moving contact unit 20, for example, two anti-sway members 34 may be arranged on one side of the moving contact unit 20, and two anti-sway members 34 may be arranged on the other side, symmetrically arranged with respect to the length direction, width direction, and / or height direction. Figures 3 to 5 In some embodiments, when different first anti-sway members 340 and second anti-sway members 341 are used, a first anti-sway member 340 and a second anti-sway member 341 can be arranged on one side of the moving contact unit 20, and a first anti-sway member 340 and a second anti-sway member 341 can also be arranged on the other side, so that they are arranged symmetrically about the length direction, width direction or height direction.

[0091] According to some embodiments of this application, the relay 1 may further include a push assembly 50, which may be coupled to the moving contact unit 20 and configured to push the moving contact unit 20. The push assembly 50 has a base 52, and an anti-sway mechanism 30 may be disposed on the base 52.

[0092] In some embodiments, the anti-sway mechanism 30 can be directly disposed on the moving contact unit 20, so that the anti-sway mechanism 30 moves with the moving contact unit 20, that is, the anti-sway mechanism 30 is directly connected to or fixed to the moving contact unit 20.

[0093] As described above, the push assembly 50 of the relay 1 is used to push the moving contact unit 20 to move in the height direction so that the stationary contact element 102 and the moving contact element 202 come into contact, and the push assembly 50 has a base 52. In this case, the anti-sway mechanism 30 can be provided on the base 52.

[0094] According to some embodiments of this application, the anti-sway mechanism 30 may include a first bracket 351 and a second bracket 352 extending from opposite sides of the base 52, respectively, and the anti-sway member 34 correspondingly extends from the first bracket 351 and the second bracket 352 toward the inner wall 112 of the housing 11, and the moving contact unit 20 may be sandwiched between the first bracket 351 and the second bracket 352.

[0095] like Figure 4 and Figure 7As shown, the first bracket 351 and the second bracket 352 extend upward along the height direction from opposite sides of the base 52, respectively. The first bracket 351 and the second bracket 352 can serve as the anti-sway body of the anti-sway mechanism 30 as described above, so that the anti-sway member 34 extends from the first bracket 351 and the second bracket 352 toward the inner wall 112 of the housing 11.

[0096] The moving contact unit 20 can be sandwiched between the first support 351 and the second support 352, which are arranged to be adjacent to the moving contact unit 20, so that the swinging motion of the moving contact unit 20 can be transmitted to the first support 351 and the second support 352. In some embodiments, in order to ensure that the first support 351 and the second support 352 can be tightly adjacent to the moving contact unit 20, the first support 351 and the second support 352 can be connected to the moving contact unit 20 by additional constraint devices, such as snap-fit ​​devices, sliding constraint devices (e.g., allowing the moving contact unit 20 to slide relative to the first support 351 and the second support 352 in the height direction but not in the length or width direction), etc.

[0097] The support structure extending upward from the base 52 is usually an existing structure in the relay. Therefore, using it as part of the anti-sway mechanism can simplify the structure, reduce the difficulty of processing, save costs, and does not require major modifications to the existing relay structure.

[0098] According to some embodiments of this application, a reinforcing rib 114 may be formed on the inner wall 112 of the housing 11, and the anti-sway member 34 of the anti-sway mechanism 30 may be positioned close to the reinforcing rib 114.

[0099] Typically, to maintain the structural strength of the housing 11 and prevent it from cracking, reinforcing ribs 114 can be formed on the inner wall 112 of the housing 11. The reinforcing ribs 114 can typically extend along the height direction. According to an embodiment of this application, the anti-sway member 34 of the anti-sway mechanism 30 can be positioned close to the reinforcing rib 114, but not in contact with it.

[0100] The anti-sway component 34 is positioned close to the reinforcing rib 114, which can provide a favorable restraint effect and prevent swaying motion from damaging the shell 11.

[0101] The anti-sway mechanism of the relay according to this application can prevent the movement of the moving contact unit from affecting the normal operation of the relay, and can restrain the swaying movement of the moving contact unit when swaying occurs. At the same time, the anti-sway mechanism of the relay according to this application does not require major modifications to the structure of existing relays, and can significantly reduce production costs.

[0102] 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.
