Description

Technical Field

[0001] The present invention relates to the technical field of switches, and in particular to a contact assembly and a switch. Background Art

[0002] A rocker switch is a commonly used electrical device used to control the on / off state of an electrical circuit. A rocker switch typically consists of a fixed frame, a button assembly, a stationary contact assembly, and a moving contact assembly (i.e., a rocker assembly). The stationary contact assembly is fixed to the fixed frame, while the moving contact assembly is swingably mounted to the fixed frame. The button assembly is swingably mounted to the fixed frame and engages with the moving contact assembly. When the button assembly is pressed by an external force, it drives the moving contact assembly to swing, causing the moving contact assembly to contact or separate with the stationary contact assembly, thereby switching the circuit on and off.

[0003] The related art provides a method for improving the above-mentioned problem by increasing the elasticity of the seesaw on which the movable contact assembly sets the contacts, or increasing the elasticity of the connecting plate on which the static contact assembly sets the contacts, to improve the problem of bouncing that easily occurs when the movable contact assembly and the static contact assembly are closed, thereby reducing the generation of arcs and improving the problem of ablation and adhesion between the contacts of the movable contact assembly and the static contact assembly.

[0004] However, the switch provided by the related technology cannot completely avoid the problem of the contacts of the moving contact assembly and the contacts of the static contact assembly sticking together due to ablation, and is very likely to fail when the switch is forcibly turned on and the contacts of the moving contact assembly and the contacts of the static contact assembly are forcibly separated. Summary of the Invention

[0005] The present invention provides a contact assembly and a switch, wherein the contact assembly can be used as either a movable contact assembly or a stationary contact assembly. The contact assembly not only alleviates the problem of bouncing when the movable and stationary contact assemblies are closed, thereby reducing arcing and alleviating the problems of contact erosion and adhesion caused by arcing, but also ensures that the movable and stationary contact assemblies can be successfully separated by force-pushing the switch even if erosion or adhesion occurs between the movable and stationary contact assemblies.

[0006] The embodiments of the present invention can be implemented as follows: In a first aspect, the present invention provides a contact assembly for use as a moving contact assembly and / or a stationary contact assembly, comprising: Support members; A connecting member, the connecting member is stacked on the supporting member, and the connecting member has a first connecting portion and a second connecting portion, the first connecting portion is connected to the supporting member; and A contact connected to the second connection portion; wherein, The elasticity of at least the portion from the first connection portion to the second connection portion is greater than that of the support member, and when the contact is impacted by an external force, the contact and the second connection portion can elastically displace around the first connection portion in a direction away from the support member.

[0007] In an optional embodiment, the support member extends to the second connecting portion.

[0008] In an alternative embodiment, parts of the support member are distributed around the periphery of the contact.

[0009] In an optional embodiment, the support member is provided with a slot, the slot walls of which are distributed on the periphery of the contact and have gaps with the peripheral wall of the contact; and / or, The support is provided with a socket, and the contact can be movably inserted into the socket. When the contact is inserted into the socket, a gap is distributed between the outer peripheral wall of the contact and the hole wall of the socket.

[0010] In an optional embodiment, an end portion of the support member protrudes from an end of the second connecting portion away from the first connecting portion.

[0011] In an optional embodiment, the connecting member is provided with a hollow structure, and the hollow structure extends between the first connecting portion and the second connecting portion.

[0012] In an optional embodiment, the first connecting portion is rigidly connected to the support member.

[0013] In an optional embodiment, the first connecting portion is clamped or welded to the support member.

[0014] In an optional embodiment, the thickness of the supporting member is greater than the thickness of the connecting member.

[0015] In an optional embodiment, the connecting member further includes a third connecting portion, the first connecting portion, the third connecting portion and the second connecting portion are sequentially connected at an angle, and the first connecting portion and the second connecting portion are respectively located on opposite sides of the third connecting portion.

[0016] In an optional embodiment, the connecting member includes two second connecting parts and two third connecting parts; the two third connecting parts are respectively connected to the two ends of the first connecting part, and the two second connecting parts are connected to the two third connecting parts in a one-to-one correspondence.

[0017] In a second aspect, the present invention provides a switch, comprising a fixing frame, a button assembly, a static contact assembly, and a moving contact assembly, wherein the static contact assembly is fixedly mounted on the fixing frame, the moving contact assembly is swingably mounted on the fixing frame, and the button assembly is swingably mounted on the fixing frame and is in transmission cooperation with the moving contact assembly; wherein, The movable contact assembly is the contact assembly of any of the aforementioned embodiments, one side of the support member is in transmission cooperation with the button assembly, and the connecting member is distributed on the side of the support member away from the button assembly; and / or, The static contact assembly is the contact assembly of any one of the aforementioned embodiments, and the connecting member is distributed on a side of the support member facing away from the moving contact assembly.

[0018] The beneficial effects of the contact assembly of the embodiments of the present invention include: the contact assembly provided by the embodiments of the present invention can be used as either a movable contact assembly or a stationary contact assembly of a switch, and the contact assembly includes a support member and a connector superimposed on the support member, wherein the elasticity of at least the first connecting portion to the second connecting portion of the connector is greater than the elasticity of the support member, so that when the contact provided at the second connecting portion is impacted by an external force, the second connecting portion of the connector can, under the elastic action of the connector itself, elastically displace about its first connecting portion relative to the support member and in a direction away from the support member (i.e., a portion of the structure of the connector can elastically deform about its first connecting end relative to the support member), thereby offsetting the impact force on the contact by the elastic action of the connector itself, thereby alleviating the problem of the contact easily bouncing repeatedly due to impact, thereby facilitating the reduction of arcing caused by contact bouncing, and improving the problems of contact ablation and adhesion. At the same time, because the connector is superimposed on the support member, the forced pulling force applied to the support member can be reliably transmitted to the connector, thereby driving the connector to move the contact, thereby increasing the probability of successful contact separation when the switch is forced to be pulled.

[0019] The switch of the embodiment of the present invention includes all the beneficial effects of the aforementioned contact assembly, for example: when the contact is impacted, the elastic effect of the connector itself can be used to offset the impact force on the contact, thereby improving the problem of the contact easily bouncing repeatedly due to impact, thereby helping to reduce the phenomenon of arcing due to contact bouncing, and improving the problems of contact burning and adhesion; moreover, it can also increase the probability of successful separation of the contacts when the switch is forced.

Therefore, it should not be understood as a limitation on the present invention.

[0027] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0028] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0029] Please refer to Figure 1 and Figure 2 This embodiment provides a switch 010, which may be a seesaw switch; the switch 010 includes: a fixing frame 100, a button assembly 200, a static contact assembly 300 and a moving contact assembly 400 (i.e., a seesaw assembly), wherein the static contact assembly 300 is fixedly mounted on the fixing frame 100, the moving contact assembly 400 is swingably mounted on the fixing frame 100, and the button assembly 200 is swingably mounted on the fixing frame 100 and is in transmission cooperation with the moving contact assembly 400; when the button assembly 200 is pressed by an external force, the button assembly 200 can drive the moving contact assembly 400 to swing, so that the moving contact assembly 400 contacts or separates from the static contact assembly 300, thereby realizing the on-off of the circuit.

[0030] The static contact assembly 300 includes a wiring terminal 310, a connecting plate 311 and a static contact 312. The wiring terminal 310 is arranged on the fixing frame 100, the connecting plate 311 is arranged on the wiring terminal 310, and the static contact 312 is connected to the connecting plate 311; the moving contact assembly 400 includes a seesaw 411 and a moving contact 412. The seesaw 411 is swingably arranged on the fixing frame 100, and the button assembly 200 is in transmission cooperation with the seesaw 411, and the moving contact 412 is arranged on the seesaw 411; when the button assembly 200 is pressed by external force, the button assembly 200 drives the seesaw 411 to swing, which can drive the moving contact 412 to move to contact or separate from the static contact 312.

[0031] The button assembly 200 includes a button 210, a transition piece 220, an elastic piece (not shown) and a pin 240. The button 210 and the transition piece 220 are assembled together. The transition piece 220 is swingably assembled on the fixing frame 100. The elastic piece is connected between the pin 240 and the transition piece 220, and the pin 240 is in contact with the seesaw 411. When the button 210 is pressed by an external force, the button 210 drives the transition piece 220 to swing relative to the fixing frame 100, so as to drive the elastic piece and the pin 240 through the transition piece 220, drive the seesaw 411 to swing, and then drive the moving contact 412 to contact or separate with the static contact 312.

[0032] It should be noted that the switch 010 also includes other structures such as the pressure plate 101, which will not be described in detail here.

[0033] The inventors have discovered that when the moving contact contacts the static contact, due to the impact force generated between the moving contact and the static contact, repeated contact and separation (i.e., bouncing) may occur between the moving contact and the static contact. In the process of repeated contact and separation between the moving and static contacts, electric arcs are easily generated, which in turn easily leads to ablation and adhesion between the moving and static contacts. By adding an elastic structure to the seesaw of the moving contact or the connecting plate of the static contact, the elastic effect of the elastic structure can be utilized to offset the impact force when the moving contact and the static contact collide with each other, thereby improving the bouncing problem between the moving contact and the static contact, reducing the generation of electric arcs, and improving the ablation and adhesion between the moving and static contacts. The above solution still cannot completely avoid the problem of the moving contact and the stationary contact sticking together due to ablation. When the moving contact and the stationary contact need to be separated, the switch must be forcibly flipped, using the transition piece of the button assembly to directly apply force to the seesaw (that is, the ball and the seesaw simultaneously apply force to the seesaw), forcibly driving the seesaw to separate the moving contact and the stationary contact. However, due to the elastic structure added to the seesaw or the connecting plate, the elastic structure undergoes elastic deformation during the forcible flip, causing the moving contact or the stationary contact to elastically displace, and the disconnection failure due to this elastic displacement. In other words, the success rate of forced disconnection is low.

[0034] It should be noted that elastic displacement of the movable contact refers to the following: as the seesaw swings, the elastic structure of the seesaw undergoes elastic deformation, causing the seesaw itself to displace. However, due to the elastic deformation of the elastic structure, the position of the movable contact itself remains unchanged (e.g., the movable contact remains bonded to the stationary contact), while the relative position between the movable contact and the seesaw changes. The understanding of elastic displacement of the stationary contact is similar to the understanding of elastic displacement of the movable contact described above and will not be repeated here.

[0035] To improve the above problems, please refer to Figure 3 and Figure 4This embodiment provides a new contact assembly as a movable contact assembly 400; the contact assembly includes a support member 500, a connector 600, and a contact (i.e., movable contact 412). The connector 600 is stacked on the support member 500, and the contact is disposed on the connector 600. Thus, the connector 600 and the support member 500 can together serve as a seesaw 411.

[0036] The connector 600 is stacked on the support member 500 and includes a first connecting portion 610 and a second connecting portion 620. The first connecting portion 610 is connected to the support member 500; the contact is connected to the second connecting portion 620. The elasticity of at least the portion from the first connecting portion 610 to the second connecting portion 620 is greater than that of the support member 500. When the contact is impacted by an external force, the contact and the second connecting portion 620 can elastically displace around the first connecting portion 610 in a direction away from the support member 500. One side of the support member 500 is in driving engagement with the button assembly 200, specifically, with the pin 240. The connector 600 is located on the side of the support member 500 facing away from the button assembly 200.

[0037] When the contact arranged on the second connecting part 620 is hit by an external force (that is, when the moving contact 412 contacts the static contact 312), the second connecting part 620 of the connector 600 can be elastically displaced around its first connecting part 610 relative to the support member 500 and in a direction away from the support member 500 under the elastic action of the connector 600 itself (that is, part of the structure of the connector 600 will be elastically deformed around its first connecting end relative to the support member 500), so that the impact force on the contact is offset by the elastic action of the connector 600 itself (that is, the elastic action can offset the rebound force F1 exerted by the static contact 312 on the moving contact 412), thereby improving the problem of the contact easily bouncing repeatedly due to impact, thereby helping to reduce the phenomenon of arcing due to contact bouncing, and improving the problems of contact ablation and adhesion. At the same time, since the connecting member 600 is stacked on the supporting member 500, when the switch 010 is forced to be dialed, the supporting member 500 is subjected to the forced dialing force F2 provided by the transition member 220, which can be reliably transmitted to the connecting member 600, and the supporting member 500 can be used to prevent the connecting member 600 from elastically deforming in the direction close to the static contact 312 due to the adhesive force, and then the connecting member 600 can be reliably driven by the supporting member 500 to drive the contact 412 to move in the direction away from the static contact 312 until it is separated from the static contact 312, thereby increasing the probability of successfully separating the contacts when the switch 010 is forced to be dialed.

[0038] Optionally, the thickness of the support member 500 is greater than the thickness of the connecting member 600; in this way, it can ensure that the elasticity of the connecting member 600 is greater than the elasticity of the support member 500, so as to utilize the reliable elastic action of the connecting member 600 to effectively offset the impact force exerted on the moving contact 412, thereby improving the bouncing problem and reducing the generation of electric arcs; moreover, when it is necessary to forcibly turn on the switch 010, the thicker support member 500 can be utilized to reliably prevent the connecting member 600 from elastic deformation due to the adhesive force, and ensure the reliability and success rate of the forced separation of the moving contact 412 and the static contact 312.

[0039] Of course, in other embodiments, the connecting member 600 may be made of a material with greater elasticity, and the supporting member 500 may be made of a material with less elasticity, to ensure that the elasticity of the connecting member 600 is greater than that of the supporting member 500 .

[0040] Please refer to Figure 3 In order to more reliably disconnect the movable contact 412 and the stationary contact 312 when the switch 010 needs to be forcibly switched, the support member 500 can be extended as close to the contacts as possible, that is, the support member 500 can be extended to the second connecting portion 620. In this way, the support area of the support member 500 for the connecting member 600 can be increased. When the switch 010 is forcibly switched, the support member 500 can more reliably prevent the connecting member 600 from elastically deforming in the direction close to the stationary contact 312, thereby ensuring the reliability of the support member 500 driving the connecting member 600 to separate the movable contact 412 from the stationary contact 312, thereby improving the success rate of forcibly disconnecting the movable contact 412 and the stationary contact 312.

[0041] Optionally, part of the support member 500 is distributed on the periphery of the contact. When the switch 010 needs to be forced to turn, the support member 500 can be used to more reliably separate the moving contact 412 from the static contact 312 to ensure the success rate of forced disconnection.

[0042] Alternatively, see Figure 3 and Figure 5 The support member 500 is provided with a socket 521, into which the contact can be movably inserted. When the contact is inserted into the socket 521, a gap is distributed between the outer peripheral wall of the contact and the hole wall of the socket 521. When the switch 010 needs to be forcibly turned on, the support member 500 driven by the transition member 220 can, on the one hand, reliably transmit the driving force to the connector 600, and on the other hand, can reliably prevent the connector 600 from deforming in a direction approaching the static contact 312 by utilizing the support member 500. In this way, the movable contact 412 provided on the connector 600 can, under the action of the support member 500, reliably move in a direction away from the static contact 312, thereby improving the success rate of forced separation between the movable contact 412 and the static contact 312.

[0043] It should be noted that the contact can be movably inserted into the socket 521 , which means that the contact can be inserted into or removed from the socket 521 when the connector 600 undergoes elastic deformation.

[0044] Alternatively, see Figure 3 The end of the support member 500 protrudes from the end of the second connecting portion 620 away from the first connecting portion 610. Increasing the length of the support member 500 can further increase the area covered by the support member 500 on the connecting member 600, ensuring that the forced dialing force applied to the support member 500 can be reliably transmitted to the connecting member 600, ensuring that the connecting member 600 can reliably forcibly disconnect the moving contact 412 and the static contact 312.

[0045] Of course, in other embodiments, the end of the support member 500 is flush with the end of the second connection portion 620 away from the first connection portion 610, or is retracted relative to the end of the second connection portion 620 away from the first connection portion 610, which is not specifically limited here.

[0046] Please refer to Figure 6 In other embodiments, a slot 522 is provided at the end of the support member 500 , and the slot wall of the slot 522 is distributed on the periphery of the contact and has a gap with the peripheral wall of the contact.

[0047] Alternatively, see Figure 5 The connector 600 further includes a third connecting portion 630. The first connecting portion 610, the third connecting portion 630, and the second connecting portion 620 are sequentially connected at an angle, with the first connecting portion 610 and the second connecting portion 620 located on opposite sides of the third connecting portion 630. The structure and shape of the support member 500 match those of the connector 600 to ensure that the support member 500 can reliably support the connector 600, thereby improving the success rate of forced insertion.

[0048] Among them, the position of the support member 500 corresponding to the first connecting part 610 is in transmission cooperation with the button assembly 200; specifically, the position of the support member 500 corresponding to the first connecting part 610 is in transmission cooperation with the ball 240 and / or the transition member 220, that is, when the button 210 is pressed by external force, the support member 500 can reliably drive the first connecting part 610, the second connecting part 620 and the third connecting part 630 of the connecting member 600 to swing, so as to realize the contact or separation of the moving contact 412 and the static contact 312.

[0049] Optionally, the connecting member 600 includes two second connecting parts 620 and two third connecting parts 630; the two third connecting parts 630 are respectively connected to the two ends of the first connecting part 610, and the two second connecting parts 620 are connected to the two third connecting parts 630 in a one-to-one correspondence; the two third connecting parts 630 located at both ends of the first connecting part 610 are distributed on the same side of the first connecting part 610, and the second connecting part 620 connected to any one of the third connecting parts 630 extends in a direction away from the first connecting part 610.

[0050] Optionally, the angle between the first connection part 610 and the third connection part 630, and the angle between the third connection part 630 and the corresponding second connection part 620 are both obtuse angles, which can be 100°, 110°, 120°, etc., and are not specifically limited here.

[0051] Of course, in other embodiments, at least one of the angle between the first connection portion 610 and the third connection portion 630 and the angle between the third connection portion 630 and the corresponding second connection portion 620 may also be a direct angle or an acute angle, which is not specifically limited here.

[0052] Optionally, each second connecting portion 620 is provided with a contact, and the corresponding switch 010 includes two static contact assemblies 300 .

[0053] Of course, in other embodiments, a contact may be provided on only one of the second connecting portions 620 , and the corresponding switch 010 includes only one static contact assembly 300 .

[0054] Please understand, please refer to Figure 5 The shape and structure of the support member 500 and the connecting member 600 are compatible. Specifically, the support member 500 includes a first support portion 510, two second support portions 520, and two third support portions 530. The two third support portions 530 are connected to both ends of the first support portion 510, and the third support portions 530 are connected to the first support portion 510 at an angle. The two second support portions 520 are connected to the two third support portions 530 in a one-to-one correspondence at an angle. The first support portion 510 and the first connecting portion 610 are stacked together and connected to each other, the second support portion 520 and the second connecting portion 620 are stacked together, the second support portion 520 is provided with a socket 521, and the third support portion 530 and the third connecting portion 630 are stacked together. This configuration ensures that the support member 500 can reliably support the connecting member 600, thereby improving the success rate of forced dialing.

[0055] The first connecting portion 610, the second connecting portion 620 and the third connecting portion 630 are connected in a manner including but not limited to integral molding or welding. Accordingly, the first supporting portion 510, the second supporting portion 520 and the third supporting portion 530 are connected in a manner including but not limited to integral molding or welding.

[0056] In some embodiments, the distance from the contact to the first connection portion 610 can be increased, that is, the length of at least one of the second connection portion 620 and the third connection portion 630 can be increased, and the elasticity of the third connection portion 630 and the second connection portion 620 relative to the support member 500 can be further increased to fully improve the problem of repeated bouncing when the moving contact 412 contacts the static contact 312.

[0057] Alternatively, the distance between the contact and the first connection portion 610 may be increased by arranging the contact as far as possible at an end of the second connection portion 620 that is farthest away from the third connection portion 630 .

[0058] Optionally, in order to ensure at least partial elasticity of the connector 600 and to reliably utilize the elasticity of the connector 600 to improve the problem of repeated bouncing when the moving contact 412 contacts the static contact 312, please refer to Figure 5 The connecting member 600 is provided with a hollow structure 631 , which extends between the first connecting portion 610 and the second connecting portion 620 .

[0059] Illustratively, the hollow structure 631 is a long hole provided in the third connection portion 630 , and both ends of the long hole extend to the first connection portion 610 and the second connection portion 620 , respectively.

[0060] Optionally, in order to enable the second connection part 620, the third connection part 630 and the contact to reliably move elastically around the first connection part 610 in a direction away from the support member 500; the first connection part 610 is configured to be rigidly connected to the first support part 510 of the support member 500.

[0061] Rigid connection means that the first connecting portion 610 and the first supporting portion 510 are fixedly connected, and relative movement or rotation between the two is not allowed; this connection method can ensure the integrity and stability of the connection part.

[0062] Alternatively, see Figure 3 and Figure 5 The first connecting portion 610 is engaged with the first supporting portion 510 of the supporting member 500. For example, the first connecting portion 610 is provided with a buckle 611, and the buckle 611 is engaged with the first supporting portion 510; or the first supporting portion 510 is provided with a buckle 611, and the buckle 611 is engaged with the first connecting portion 610.

[0063] Of course, in other implementations, please refer to Figure 7 , the first connecting portion 610 is welded to the first supporting portion 510 of the supporting member 500. The welding method not only ensures the reliability of the rigid connection, but also enhances the conductive performance.

[0064] In order to improve the problem that the moving contact 412 and the static contact 312 fail to disconnect when the switch 010 is forced to be dialed; please refer to Figure 8 In other embodiments, the above-mentioned contact assembly can also be used as the static contact assembly 300; wherein, the contact of the contact assembly serves as the static contact 312, and the connector 600 of the contact assembly is distributed on the side of the support member 500 away from the movable contact assembly 400, that is, the support member 500 and the connector 600 can jointly serve as the connecting plate 311. When the movable contact 412 contacts the static contact 312, the connector 600 can elastically deform relative to the support member 500 in a direction away from the support member 500. The elastic action of the connector 600 offsets the impact force provided by the movable contact 412, thereby improving the problem of repeated contact and separation between the movable contact 412 and the static contact 312, thereby reducing the generation of arcs. When the switch 010 is forced to turn, the connector 600 is supported by the support member 500 and is not easily elastically deformed toward the movable contact 412, thereby improving the problem of the static contact 312 elastically displacing and being unable to reliably forcibly separate from the movable contact 412.

[0065] It should be understood that in an embodiment where the contact assembly is used as the static contact assembly 300, the connector 600 may only include a first connecting portion 610 and a second connecting portion 620 that are connected to each other, and the angle between the first connecting portion 610 and the second connecting portion 620 may be 180°, 170°, 90°, etc., which is not specifically limited here.

[0066] When the switch 010 of this embodiment is in use, the button 210 can be dialed to drive the moving contact assembly 400 through the button 210, the transition piece 220, the elastic piece and the pin 240, thereby realizing the contact or separation of the moving contact 412 and the static contact 312; wherein, when the moving contact 412 contacts the static contact 312, the third connection part 630 and the second connection part 620 of the connecting member 600 can both be elastically deformed around the first connection part 610 in a direction away from the support member 500 relative to the support member 500, and the elastic action can offset the reaction force applied by the static contact 312 to the moving contact 412.

[0067] In summary, the contact assembly of the present invention can be used in switch 010 as either the movable contact assembly 400 or the stationary contact assembly 300. This contact assembly not only alleviates the bouncing problem that occurs when the movable contact assembly 400 and the stationary contact assembly 300 are closed, thereby reducing arcing and alleviating the problems of contact erosion and adhesion caused by arcing; it also ensures that even if the movable contact assembly 400 and the stationary contact assembly 300 experience erosion or adhesion, the movable contact assembly 400 and the stationary contact assembly 300 can be successfully separated by forced activation of switch 010.

[0068] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
