AI Technical Summary
In rocker switches, uneven force on the rocker can cause it to bounce, resulting in electric arcs and reducing its service life.
The rocker switch is designed with a transition component and a contact structure between the transition component and the rocker assembly, so that the transition component always abuts against the third contact part of the rocker assembly, ensuring that the rocker is subjected to balanced force and preventing bouncing.
This avoids the generation of electric arcs and increases the service life of the rocker switch.

Abstract
Description
Technical Field
[0001] This application relates to the field of switch technology, specifically to a rocker switch. Background Technology
[0002] A switch is an electrical component in a circuit used to control the conduction and interruption of current. One common type of switch is the rocker switch. In related technologies, the rocker switch typically has its rocker arm supported on a base, and a compression spring built into a transition element provides contact pressure between the rocker arm and the base. As the rocker switch opens and closes, the bottom of the transition element slides back and forth between the two ends of the rocker arm, causing the rocker arm to swing back and forth on the base. This causes the contacts on the rocker arm to separate and make contact with their corresponding contacts, thus opening or closing the circuit.
[0003] However, in the rocker switch mentioned above, because the force on each position of the rocker is not uniform during the sliding process of the transition component, it is inevitable that the rocker will briefly detach from the support due to bouncing. During this process, an electric arc will be generated between the rocker and the support. Long-term use can easily lead to problems such as burning and welding, thereby reducing the service life of the rocker switch. Summary of the Invention

[0059] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0061] This application provides a rocker switch, which can be a single-pole switch or a double-pole switch. A double-pole switch, for example, may include two sets of rocker assemblies and two sets of terminal block assemblies. The rocker switch is typically connected between an electrical device and an external power line, used to conduct electricity between the device and the external power line and to interrupt the electrical connection between them. Correspondingly, the rocker switch has an on state and a off state. When the rocker switch is in the on state, the electrical device and the external power line are electrically connected; when the rocker switch is in the off state, the electrical connection between the device and the external power line is interrupted.
[0062] like Figure 1 As shown, the rocker switch provided in this application embodiment may include a base 1, and a transition member 2, a rocker assembly 3, and a terminal assembly 4 assembled on the base 1; the transition member 2 is rotatably connected to the base 1, and the transition member 2 has a first abutment portion 21 and a second abutment portion 22; the rocker assembly 3 is elastically connected to the base 1, and the rocker assembly 3 includes a third abutment portion 31; wherein when the rocker switch is in the open state, the third abutment portion 31 abuts against the first abutment portion 21, and the terminal assembly 4 is electrically connected to the rocker assembly 3; when the rocker switch is in the closed state, the third abutment portion 31 abuts against the second abutment portion 22, and the terminal assembly 4 is electrically disconnected from the rocker assembly 3.
[0063] See Figure 1 The base 1 has a receiving cavity, and the transition member 2, the rocker assembly 3, and the terminal assembly 4 are all assembled in the receiving cavity of the base 1. The receiving cavity of the base 1 has an open end. In this embodiment, for ease of description, the shell wall of the base 1 opposite to the open end of the receiving cavity is defined as the "bottom wall".
[0064] The transition member 2 is rotatable relative to the base 1, wherein when the rocker switch is pressed, the pressing force is transmitted to the transition member 2, thereby actuating the transition member 2 relative to the base 1. In this embodiment, the transition member 2 abuts against the third abutment portion 31 of the rocker assembly 3, and in two adjacent actuations of the transition member 2, the first abutment portion 21 and the second abutment portion 22 alternately abut against the third abutment portion 31.
[0065] The rocker assembly 3 may include a rocker and a third abutment 31 connected to the rocker. The third abutment 31 may be triangular prism, spherical, cylindrical, or a structure integrally formed with the rocker.
[0066] When the transition piece 2 is actuated, the terminal block assembly 4 can be electrically connected to the rocker assembly 3 or resistively disconnected from the rocker assembly 3. When the terminal block assembly 4 is electrically connected to the rocker assembly 3, the electrical equipment connected to the rocker switch can access an external power supply circuit and draw power from it. When the terminal block assembly 4 is resistively disconnected from the rocker assembly 3, the electrical equipment connected to the rocker switch is disconnected from the external power supply circuit and therefore cannot draw power from it.
[0067] In summary, in the embodiments of this application, as Figure 1 As shown, a first abutment portion 21 and a second abutment portion 22 are provided at one end of the transition member 2 near the rocker assembly 3. As the rocker switch is pressed continuously, the transition member 2 rotates, and thus the first abutment portion 21 and the second abutment portion 22 alternately abut against the third abutment portion 31 of the rocker assembly 3. See, for example, [reference needed]. Figure 2 When the rocker switch is in the open state, the first abutment portion 21 of the transition member 2 abuts against the third abutment portion 31, at which time the rocker assembly 3 and the terminal assembly 4 are electrically connected. As the rocker switch changes from the open state to the closed state, the transition member 2 rotates, causing the first abutment portion 21 to gradually move away from the third abutment portion 31 and the second abutment portion 22 to gradually approach the third abutment portion 31. Simultaneously, the rocker assembly 3 rotates, thus, when the rocker switch is in the closed state, see [reference needed]. Figure 3 The second abutting part 22 will abut against the third abutting part 31, at which point the resistance between the rocker assembly 3 and the terminal assembly 4 will be broken. Compared with rocker switches in related technologies, since the transition part 2 of the rocker switch provided in this embodiment is always abutted against the third abutting part 31 of the rocker assembly 3, the problem of the rocker bouncing and briefly detaching from the support due to uneven force during use is solved, the generation of electric arc is avoided, and the service life of the rocker switch is improved.
[0068] In some embodiments of this application, the terminal assembly 4 may include a first terminal assembly 41 and a second terminal assembly 42; the first terminal assembly 41 is electrically connected to the rocker assembly; the second terminal assembly includes a second terminal 421, a second connecting piece 422, and a second contact; the second terminal 421 and the second connecting piece 422 are electrically connected, and the second contact 423 is located on the second connecting piece; the rocker assembly 3 includes a first rocker 32 and a third contact 36; wherein, when the third contact 36 is in contact with the second contact 423, the terminal assembly 4 and the rocker assembly 3 are electrically connected; when the third contact 36 is separated from the second contact 423, the resistance between the terminal assembly 4 and the rocker assembly 3 is broken.
[0069] The structure of the first terminal assembly 41 may be the same as or different from that of the second terminal assembly 42. For example, the first terminal assembly 41 may include a first terminal, a first connecting piece, and a first contact, with the first terminal and the first connecting piece electrically connected and the first contact located on the first connecting piece; or, the first terminal assembly 41 may also include only a first terminal and a conductive element, with the first terminal connected to and electrically conductive to the first rocker plate 32 through the conductive element.
[0070] The first terminal and the second terminal 421 are respectively one of the incoming terminal and the outgoing terminal. For example, the first terminal can be the incoming terminal, which is always electrically connected to the rocker assembly 3; the second terminal 421 can be the outgoing terminal.
[0071] The number of third contacts 36 can be one or two. When there is only one third contact 36, it corresponds to the second terminal 421. When there are two third contacts 36, they correspond to the first terminal and the second terminal 421 respectively. When the terminal assembly 4 and the rocker assembly 3 are electrically connected, the third contact 36 of the rocker assembly 3 actually contacts the corresponding second terminal 421 to conduct the circuit. When the terminal assembly 4 and the rocker assembly 3 are electrically disconnected, the third contact 36 of the rocker assembly 3 actually separates from the corresponding second terminal 421 to disconnect the circuit. For example, the first contact, the second contact 423, and the third contact 36 can be made of silver to provide better conductivity.
[0072] In some embodiments of this application, such as Figure 4 As shown, one end of the first rocker 32 is connected to the base 1, and the other end is suspended and corresponds to the position of the second connecting piece 422.
[0073] In the above embodiment, the first rocker 32 can be a cantilever structure with one end suspended. When actuated by the transition member 2, the suspended end of the first rocker 32 can rotate under pressure, thereby moving away from the second connecting piece 422 or contacting the second contact point 423 on the second connecting piece 422.
[0074] The first rocker arm 32 can be directly connected to the base 1, or indirectly connected to the base 1. See, for example... Figure 4 The rocker assembly 3 may further include a connector 35, which is fixed to the bottom wall 14 of the base 1 and vertically connected to the first rocker 32, wherein the portion of the first rocker 32 connected to the connector 35 is away from the suspended end of the first rocker 32. Figure 4 As shown, the input terminal and the connector 35 can be arranged opposite each other on both sides of the first rocker 32, and the input terminal is in contact with or connected to the first rocker 32; alternatively, the connector 35 can also be made of conductive material, and the input terminal is directly connected to or abuts against the connector 35. In some embodiments, the connector 35 and the first rocker 32 can be an integrally formed structure.
[0075] Optionally, such as Figure 4 As shown, the third abutment 31 can be located in the middle of the first rocker 32 or closer to the suspended end of the first rocker 32, so that the torque when the first rocker 32 rotates is longer, making it easier and less strenuous to press.
[0076] In other embodiments of this application, such as Figure 5 As shown, the rocker assembly 3 includes a second rocker 33 and an elastic member 34; one end of the elastic member 34 is connected to or abuts against the base 1, and the other end is connected to or abuts against the side of the second rocker 33 away from the third abutment portion 31, so that both ends of the second rocker 33 are suspended.
[0077] In the above embodiment, the second rocker 33 is a seesaw-like structure with both ends suspended. One end of the second rocker 33 corresponds to the position of the first connecting piece, and the other end corresponds to the position of the second connecting piece 422. When actuated by the transition member 2, the second rocker 33 rotates under pressure, which manifests as the two ends of the second rocker 33 alternately rising and falling, so that the other end of the second rocker 33 moves away from or close to the second connecting piece 422 and contacts the second contact point 423.
[0078] Optionally, such as Figure 5 As shown, the third abutment 31 can be located in the middle of the second rocker 33, and the elastic member 34 also abuts against the middle of the second rocker 33. In this case, the elastic member 34 and the third abutment 31 can be arranged opposite each other on both sides of the second rocker 33; or, the third abutment 31 can be located between the elastic member 34 and one end of the second rocker 33 corresponding to the second connecting piece 422. Under the above arrangement, the pressing force required when pressing the second rocker 33 is relatively smaller, thus making it easier and less strenuous.
[0079] For example, the elastic element 34 can be a spring. Figure 5As shown, a spring fixing post 141 is provided at a corresponding position on the base 1. The length of the spring fixing post 141 is less than the length of the spring. The spring is sleeved on the spring fixing post 141, and the two ends of the spring abut against the bottom wall 14 of the base 1 and the second rocker 33, respectively. Generally speaking, when the rocker switch is in the open state, the extension direction of the spring (which can also be understood as the direction of the elastic force provided by the spring) is perpendicular to the second rocker 33. Optionally, the shape of the spring can be circular, rectangular, tower-shaped, etc.
[0080] In this embodiment, the rocker assembly 3 is positioned and assembled using multiple positioning and / or limiting members disposed on the base 1. For example... Figure 6 As shown, at least two positioning members 11 are provided on the base 1; the at least two positioning members 11 are respectively located on both sides of the second rocker 33 in the width direction, and are used to restrict the movement of the second rocker 33 in the width direction.
[0081] exist Figure 6 Two positioning members 11 are shown, located on opposite sides of the second rocker 33 in the width direction, with each positioning member 11 in contact with the second rocker 33. In some embodiments, a certain gap may exist between each positioning member 11 and the second rocker 33, as long as it ensures that the second rocker 33 will not deflect or fall off within the gap. The positioning members 11 are used to limit the offset of the second rocker 33 in the width direction, preventing it from shifting or allowing only a small offset, to avoid the second rocker 33 from detaching from the elastic member 34 during rocker switch operation or from tilting when actuated by the transition member 2.
[0082] See Figure 7 A second limiting member 12 is provided on the base 1 to restrict the movement of the second rocker 33 away from the elastic member 34. The second limiting member 12 is used to limit the amount of movement of the second rocker 33 in the thickness direction, to prevent it from being subjected to excessive elastic force and detaching from the elastic member 34, or even from its mounting position on the base 1.
[0083] In some embodiments of this application, such as Figure 7 As shown, a first limiting member 331 may be provided on the second rocker 33, the first limiting member 331 extending from the side wall in the width direction of the second rocker 33; the second limiting member 12 includes a hook 121, the hook 121 being used to hook the first limiting member 331 on the side of the second rocker 33 away from the elastic member 34.
[0084] like Figure 7As shown, the second rocker 33 has two sidewalls in the width direction, which are opposite to or in contact with at least two positioning members 11. The first limiting member 331 can be, for example, a limiting shaft, which extends from at least one sidewall in the width direction. When the second rocker 33 moves away from the elastic member 34 due to the elastic force provided by the elastic member 34, the limiting shaft is hooked by the corresponding hook 121, thereby limiting the amount of movement of the second rocker 33 in the thickness direction. At the same time, due to the hook-shaped structure of the hook 121, the amount of movement of the second rocker 33 can also be limited in the length direction.
[0085] In other embodiments of this application, such as Figure 8 As shown, the second limiting member 12 may include a latch 122, which is located on the side of the second rocker 33 away from the elastic member 34. The orthographic projection of the latch 122 on the bottom wall 14 of the base 1 and the orthographic projection of the second rocker 33 on the bottom wall 14 of the base 1 overlap. Therefore, when the second rocker 33 moves away from the elastic member 34 due to the elastic force provided by the elastic member 34, the second rocker 33 will be blocked by the latch 122, thereby achieving the purpose of limiting the amount of movement of the second rocker 33 in the thickness direction.
[0086] Wherein, when the second limiting member 12 includes a hook 121 and a buckle 122, the hook 121 and the buckle 122 respectively correspond to the opposite ends of the second rocker 33. For example, as Figure 7 As shown, one end of the second rocker 33 is connected to a limiting shaft and corresponds to the hook 121; the other end of the second rocker 33 corresponds to the buckle 122. The hook 121 and the buckle 122 are located at the same height on the base 1. Therefore, when the second rocker 33 is moved away from the elastic element 34 by the elastic force provided by the elastic element 34, both ends of the second rocker 33 abut against the hook 121 and the buckle 122 respectively. Thus, both ends of the second rocker 33 are evenly stressed and remain parallel to the bottom wall 14 of the base 1, making it less likely to tilt or fall off. In one possible case, when the rocker switch is in the open state, both ends of the second rocker 33 abut against the hook 121 and the buckle 122 respectively.
[0087] It should be noted that at least one of the hooks 121 and buckles 122 is elastic to facilitate the assembly of the second rocker 33. Taking the elasticity of the buckle 122 as an example, during the process of the second rocker 33 entering the mounting position on the base 1, the buckle 122 will avoid the second rocker 33 under the action of external force, thereby facilitating the smooth entry of the second rocker 33. However, in the direction of the second rocker 33's withdrawal, the buckle 122 will not avoid it, but will instead play a blocking and limiting role.
[0088] like Figure 8As shown, the surface of the latch 122 facing away from the second rocker 33 is inclined, and the direction of inclination of the inclined surface is closer to the middle position of the second rocker 33 as it gets closer to the bottom wall 14 of the base 1. This inclined surface helps the second rocker 33 to smoothly enter the mounting position on the base 1 during assembly.
[0089] Optionally, the surface of the buckle 122 facing the second rocker 33 can be parallel to the bottom wall 14 of the base 1, so that when the second rocker 33 is moved away from the elastic member 34 by the elastic force provided by the elastic member 34, the surface can act as a blockage.
[0090] In the embodiments of this application, the first abutting portion 21 and the second abutting portion 22 have the same type of structure, and the third abutting portion 31 is a structure adapted to them. For example, the first abutting portion 21 and the second abutting portion 22 are one of a recess and a protrusion, and the third abutting portion 31 is the other of a recess and a protrusion. See also Figure 10 The first abutting part 21 and the second abutting part 22 are both recessed parts, while the third abutting part 31 is a protruding part. Generally speaking, the fit between the protruding part and the recessed part is relatively more stable.
[0091] See Figure 1 , 11 In some embodiments of this application, the rocker switch further includes a pressure plate 5 and a button 6; the pressure plate 5 is assembled in the receiving cavity of the base 1, the rocker assembly 3 and the terminal assembly 4 are both located between the pressure plate 5 and the bottom wall 14 of the base 1, and the transition member 2 is rotatably connected to the pressure plate 5; the button 6 is connected to the side of the transition member 2 away from the pressure plate 5.
[0092] Users can press a button to toggle the rocker switch between the on and off states. For example... Figure 11 As shown, when the rocker switch is in the open state, button 6 abuts against one side of base 1, and the vertex of the curved surface of the third abutting part 31 abuts against the vertex of the curved surface of the first abutting part 21. The vertex of the curved surface is either the lowest point on the curved surface corresponding to the recessed part, or the highest point on the curved surface corresponding to the protruding part. Figure 12 As shown, when the rocker switch is in the off state, the button 6 abuts against the other side of the base 1, and the curved vertex of the third abutting part 31 abuts against the curved vertex of the second abutting part 22.
[0093] In some embodiments of this application, such as Figure 13As shown, the angle of the first positioning angle corresponding to the first abutting part 21 is 1 to 3 times the angle of the flip angle of the button 6. The first positioning angle is the angle between the perpendicular line from the vertex of the curved surface of the first abutting part 21 to the rotation axis of the transition member 2 and the center line of the button 6; and / or, the angle of the second positioning angle corresponding to the second abutting part 22 is 1 to 3 times the angle of the flip angle of the button 6. The second positioning angle is the angle between the perpendicular line from the vertex of the curved surface of the second abutting part 22 to the rotation axis of the transition member 2 and the center line of the button 6.
[0094] For ease of description, in Figure 13 In this embodiment, the flip angle of button 6 is marked as "θ", the first positioning angle corresponding to the first abutting part 21 is marked as "α", and the second positioning angle corresponding to the second abutting part 22 is marked as "β". It should also be noted that, in this embodiment, the center line of button 6 refers to the center line that runs through button 6 along its thickness direction. Figure 13 The center is represented by a dashed line between the first positioning angle α and the second positioning angle β.
[0095] The first positioning angle α and the second positioning angle β can be the same or different. However, under normal circumstances, the degree of rotation of button 6 in the open and closed states needs to be consistent. To achieve this, the rotation axis of button 6 can be designed to pass through the center line of button 6. At the same time, based on the structure of the rocker switch provided in the embodiments of this application, and the fact that in the open state the curved vertex of the third abutting part 31 abuts against the curved vertex of the first abutting part 21, and in the closed state the curved vertex of the third abutting part 31 abuts against the curved vertex of the second abutting part 22, the first positioning angle α can also be designed to be equal to the second positioning angle β, so that the rotation angle of the transition member 2 is the same in the open and closed states, thereby ensuring that the degree of rotation of button 6 in the open and closed states is consistent, and the rotation angle is θ.
[0096] In some embodiments, the angle of the first positioning angle α is twice the angle of the flip angle θ, and the angle of the second positioning angle β is twice the angle of the flip angle θ.
[0097] Based on the rocker switch structure provided in this application embodiment, an isosceles triangle can be formed between the rotation center of the button and its two ends. The base angle of this isosceles triangle is the flip angle θ of the button 6, and the exterior angle of the vertex angle of this isosceles triangle is the rotation angle corresponding to the button and the transition member in the open and closed states, respectively. The angle of this rotation angle is 2θ. Therefore, the angles of the first positioning angle α and the second positioning angle β are both equal to twice the angle of the flip angle θ of the button 6, that is, α = β = 2θ. Thus, the relationship between the position of the curved vertices of the first abutment part 21 and the second abutment part 22 and the degree of flipping of the button 6 is defined, realizing precise control of the flip angle θ of the button 6.
[0098] In one example, such as Figure 13 and Figure 14 As shown, the flip angle θ of button 6 is 3.5°, the first positioning angle α is 7°, and the second positioning angle β is 7°; the angle corresponding to the curvature of the first abutment part 21 is 106°, the angle corresponding to the curvature of the second abutment part 22 is 130°, the transition angle between the first abutment part 21 and the second abutment part 22 is 120°, and the angle corresponding to the curvature of the third abutment part 31 is 103°. The angular tolerances of the above angles can be set according to requirements, such as 1°, 2°, 5°, 10°, etc.
[0099] In embodiments of this application, the transition member 2 and the terminal assembly 4 can be located on the same side of the rocker assembly 3 or on opposite sides of the rocker assembly 3. Specifically, in a first case, when the transition member 2 and the second connecting piece 422 are on the same side of the rocker assembly 3, the first abutment portion 21 is further away from the rocker assembly 3 than the second abutment portion 22; in a second case, when the transition member 2 and the second connecting piece 422 are on opposite sides of the rocker assembly 3, the first abutment portion 21 is closer to the rocker assembly 3 than the second abutment portion 22.
[0100] Regarding the first scenario above, such as Figure 15 As shown, when the transition member 2 and the second terminal assembly 42 are located on the same side of the rocker assembly 3, the first tilt angle corresponding to the first abutment portion 21 and the second tilt angle corresponding to the second abutment portion 22 satisfy the following relationship:
[0101]
[0102] Where γ is the first tilt angle, θ is the second tilt angle, and θ is the flip angle of button 6. The first tilt angle is the tilt angle corresponding to the slope of the orthographic projection of the side wall of the first abutment 21 on the first side onto the first plane, and the second tilt angle is the tilt angle corresponding to the slope of the orthographic projection of the side wall of the second abutment 22 on the first side onto the first plane. The first plane is a plane perpendicular to the rotation axis of the transition member 2. Wherein, when both the first abutment 21 and the second abutment 22 are recessed portions, the first side is the side away from the second terminal assembly 42; when both the first abutment 21 and the second abutment 22 are protruding portions, the first side is the side closer to the second terminal assembly 42.
[0103] In the second scenario described above, when the transition member 2 and the second terminal assembly 42 are located on opposite sides of the rocker assembly 3, the first tilt angle corresponding to the first abutment portion 21 and the second tilt angle corresponding to the second abutment portion 22 satisfy the following relationship:
[0104]
[0105] Where γ is the first tilt angle, The second tilt angle is θ, and the flip angle of button 6 is θ. The first tilt angle is the tilt angle corresponding to the slope of the orthographic projection of the sidewall of the first abutment 21 on the first side onto the first plane. The second tilt angle is the tilt angle corresponding to the slope of the orthographic projection of the sidewall of the second abutment 22 on the first side onto the first plane. The first plane is a plane perpendicular to the rotation axis of the transition member 2. When both the first abutment 21 and the second abutment 22 are recessed portions, the first side is the side away from the second terminal assembly 42 (e.g., the second contact 423). When both the first abutment 21 and the second abutment 22 are protruding portions, the first side is the side closer to the second terminal assembly 42 (e.g., the second contact 423).
[0106] When the first tilt angle and the second tilt angle satisfy the above relationship, it can be guaranteed that when the rocker switch is in the closed state, the second rocker 33 is in the tilted state, and the contacts on the second rocker 33 are separated from the second contact 423.
[0107] In summary, in the rocker switch provided in this application embodiment, the transition member 2 is an integrally formed structure. Compared with the transition member 2 in related technologies, there is no need to assemble the rocker plate assembly or the spring assembly, preventing the rocker plate assembly or the spring assembly from falling off during assembly. This facilitates automated assembly, reduces assembly workload and costs, and improves work efficiency. Simultaneously, since the transition member 2 always abuts against the third abutment portion 31 of the rocker assembly 3 in this structure, the rocker is subjected to more balanced force, and the contact between the contacts on the rocker and the corresponding contacts on the connecting piece is more reliable. This avoids the phenomenon of silver points being burned due to rocker bouncing, effectively improving switching performance.
