These drawings and written description are not intended to limit the scope of the inventive concepts in any manner, but rather to illustrate the inventive concepts to those skilled in the art by reference to specific embodiments.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Embodiments of the present application provide a rocker switch that may be a single pole switch or a double pole switch, where the double pole switch may include, for example, two sets of rocker assemblies and two sets of terminal assemblies. The rocker switch is generally connected between the electric device and an external power line for electrically connecting and disconnecting the electric device and the external power line. Correspondingly, the rocker switch has an on state and an off state, wherein when the rocker switch is in the on state, the powered device and the external power cord are electrically conducted; when the rocker switch is in the off state, the electrical connection between the powered device and the external power cord is interrupted.

As shown in fig. 1, the rocker switch provided in the embodiment of the present application may include a base 1, and a transition piece 2, a rocker assembly 3, and a terminal assembly 4 mounted to the base 1; the transition piece 2 is rotationally connected with the base 1, and the transition piece 2 is provided with a first abutting part 21 and a second abutting part 22; the rocker assembly 3 is elastically connected with the base 1, and the rocker assembly 3 comprises a third abutting part 31; wherein when the rocker switch is in the on state, the third abutting portion 31 abuts against the first abutting portion 21, and the terminal block assembly 4 is electrically conducted with the rocker assembly 3; when the rocker switch is in the off state, the third abutting portion 31 abuts against the second abutting portion 22, and the terminal block assembly 4 is electrically blocked from the rocker assembly 3.

Referring to fig. 1, base 1 has a receiving cavity, and transition piece 2, paddle assembly 3 and terminal assembly 4 are all fitted in the receiving cavity of base 1. The receiving chamber of the base 1 has an open end, and in the embodiment of the present application, a wall of the base 1 opposite to the open end of the receiving chamber is defined as a "bottom wall" for convenience of description.

The transition piece 2 is able to rotate relative to the base 1, wherein when the rocker switch is pressed, the pressing force is transferred to the transition piece 2, thereby actuating the transition piece 2 to rotate relative to the base 1. In the present embodiment, the transition piece 2 abuts against the third abutment 31 of the rocker assembly 3, and the first abutment 21 and the second abutment 22 will alternately abut against the third abutment 31 in two adjacent actuations of the transition piece 2.

The rocker assembly 3 may include a rocker and a third abutting portion 31 connected to the rocker, wherein the third abutting portion 31 may be a triangular prism, a sphere, a cylinder, or the like, and may also be a structure integrally formed with the rocker.

With transition piece 2 actuated, terminal assembly 4 can be either electrically connected to paddle assembly 3 or electrically disconnected from paddle assembly 3. When the wiring terminal assembly 4 and the rocker assembly 3 are electrically conducted, the electric equipment connected with the rocker switch can be connected to an external power supply circuit and gets electricity from the external power supply circuit; when the terminal block 4 is electrically blocked from the rocker assembly 3, the electrical equipment connected to the rocker switch is disconnected from the external power supply circuit, and thus electricity cannot be taken from the external power supply circuit.

In summary, in the embodiment of the present application, as shown in fig. 1, the first abutting portion 21 and the second abutting portion 22 are disposed at one end of the transition piece 2 close to the rocker assembly 3, and as the rocker switch is continuously pressed, the transition piece 2 rotates, so that the first abutting portion 21 and the second abutting portion 22 alternately abut against the third abutting portion 31 of the rocker assembly 3. For example, referring to fig. 2, when the rocker switch is in the on state, the first abutting portion 21 of the transition piece 2 abuts against the third abutting portion 31, and the rocker assembly 3 and the terminal assembly 4 are electrically conducted; in the process of changing the rocker switch from the on state to the off state, the transition piece 2 rotates to make the first abutting portion 21 gradually away from the third abutting portion 31 and the second abutting portion 22 gradually approach the third abutting portion 31, and meanwhile, the rocker assembly 3 rotates, so that when the rocker switch is in the off state, referring to fig. 3, the second abutting portion 22 abuts against the third abutting portion 31, and at this time, the rocker assembly 3 is electrically blocked from the terminal assembly 4. Compare in the rocker switch among the correlation technique, because the transition piece 2 of the rocker switch that this application embodiment provided supports all the time and leans on the third butt portion 31 of rocker subassembly 3, consequently solved in the use the problem that the rocker took place the spring and breaks away from the support for a short time because of the atress inequality, avoided the production of electric arc, improved the life of rocker switch.

In some embodiments of the present application, the wire terminal assembly 4 may include a first terminal assembly 41 and a second terminal assembly 42; first terminal assembly 41 is electrically connected to the rocker assembly; the second terminal assembly comprises a second terminal 421, a second connecting piece 422 and a second contact; the second terminal 421 is electrically connected to the second connection piece 422, and the second contact 423 is located on the second connection piece; paddle assembly 3 includes first paddle 32 and third contact 36; wherein, when the third contact 36 is in contact with the second contact 423, the terminal block assembly 4 is electrically connected to the rocker assembly 3; when the third contact 36 is separated from the second contact 423, the wiring terminal assembly 4 is electrically blocked from the paddle assembly 3.

The constituent structure of the first terminal assembly 41 is the same as or different from that of the second terminal assembly 42. Illustratively, the first terminal assembly 41 may include a first terminal, a first connection tab, and a first contact, the first terminal and the first connection tab being electrically connected, the first contact being located on the first connection tab; alternatively, the first terminal assembly 41 may include only a first terminal and a conductive member, and the first terminal is connected to and electrically conducted with the first rocker 32 through the conductive member.

The first terminal and the second terminal 421 are respectively one and the other of an incoming terminal and an outgoing terminal. Illustratively, the first terminal may be a line terminal that is electrically conductive with paddle assembly 3 at all times; the second terminal 421 may be an outlet terminal.

The number of the third contacts 36 may be one or two, wherein when the number is one, the third contacts 36 correspond to the second terminals 421; when the number is two, the two third contacts 36 correspond to the first terminal and the second terminal 421, respectively. When the terminal assembly 4 is electrically connected to the paddle assembly 3, it is the third contact 36 of the paddle assembly 3 that is actually in contact with the corresponding second terminal 421 to complete the circuit; when the terminal assembly 4 is electrically disconnected from the paddle assembly 3, it is the third contact 36 of the paddle assembly 3 that is actually separated from the corresponding second terminal 421 to open the circuit. For example, the first contact, the second contact 423, and the third contact 36 may be made of silver, so as to have better conductivity.

In some embodiments of the present application, as shown in fig. 4, one end of the first tilting plate 32 is connected to the base 1, and the other end is suspended and corresponds to the position of the second connecting piece 422.

In the above embodiment, the first lever 32 may be a cantilever structure with one end suspended, and when the transition piece 2 is actuated, the suspended end of the first lever 32 may rotate under pressure so as to be away from the second connecting piece 422 or contact with the second contact 423 on the second connecting piece 422.

The first rocker 32 may be directly connected to the base 1 or indirectly connected to the base 1. For example, referring to fig. 4, the rocker assembly 3 may further comprise a connecting member 35, wherein the connecting member 35 is fixed on the bottom wall 14 of the base 1 and vertically connected to the first rocker 32, and the portion of the first rocker 32 connected to the connecting member 35 is away from the suspended end of the first rocker 32. As shown in fig. 4, the line terminals and the connector 35 may be disposed opposite to each other on both sides of the first rocker 32, and the line terminals are in contact with or connected to the first rocker 32; alternatively, the connecting member 35 may be made of a conductive material, and the incoming line terminal is directly connected to or abutted against the connecting member 35. In some embodiments, the connecting member 35 and the first rocker 32 may be a unitary structure.

Alternatively, as shown in fig. 4, the third abutting portion 31 may be located at the middle position of the first tilting plate 32 or closer to the suspended end of the first tilting plate 32, so that the moment when the first tilting plate 32 rotates is longer, and the pressing is easier and more labor-saving.

In other embodiments of the present application, as shown in fig. 5, the rocker assembly 3 comprises a second rocker 33 and a spring 34; one end of the elastic element 34 is connected to or abutted against the base 1, and the other end is connected to or abutted against one side of the second tilting plate 33 far away from the third abutting part 31, so that the two ends of the second tilting plate 33 are suspended.

In the above embodiment, the second tilting plate 33 is a seesaw structure with two suspended ends. One end of the second tilting plate 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 piece 2, the second rocker 33 rotates under pressure, which is represented by the two ends of the second rocker 33 alternately rising and falling, respectively, so that the other end of the second rocker 33 is far away from the second connecting piece 422 or close to the second connecting piece 422 and contacts the second contact 423.

Alternatively, as shown in fig. 5, the third abutting portion 31 may be located at a middle position of the second tilting plate 33, and the elastic member 34 abuts at the middle position of the second tilting plate 33, in which case the elastic member 34 and the third abutting portion 31 may be disposed opposite to each other on two sides of the second tilting plate 33; alternatively, the third abutting portion 31 may be located between the elastic member 34 and an end of the second rocker 33 corresponding to the second connecting piece 422. The pressing force required to press the second rocker 33 under the above arrangement is relatively less, and thus easier and less labor intensive.

Illustratively, the elastic member 34 may be a spring. As shown in fig. 5, a spring fixing post 141 is disposed at a corresponding position on the base 1, the length of the spring fixing post 141 is smaller than that of the spring, the spring is sleeved on the spring fixing post 141, and two ends of the spring respectively abut against the bottom wall 14 of the base 1 and the second tilting plate 33. Generally, when the rocker switch is in the on state, the extending 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. Alternatively, the shape of the spring may be circular, rectangular, tower-shaped, or the like.

In the embodiment of the present application, the rocker assembly 3 is positioned and assembled by a plurality of positioning and/or limiting members disposed on the base 1. As shown in fig. 6, at least two positioning members 11 are disposed on the base 1; at least two positioning members 11 are respectively located at both sides of the second rocker 33 in the width direction for limiting the movement of the second rocker 33 in the width direction.

In fig. 6, two positioning elements 11 are shown, wherein the two positioning elements 11 are respectively located on both sides of the second tilting plate 33 in the width direction, and each positioning element 11 is in contact with the second tilting plate 33. In some embodiments, each positioning element 11 and the second tilting plate 33 may have a certain gap therebetween, as long as it is ensured that the second tilting plate 33 does not deflect and fall in the gap. The positioning member 11 is used to limit the offset of the second rocker 33 in the width direction of the second rocker 33, so that the second rocker 33 cannot be offset or can only be offset by a small amount, thereby preventing the second rocker 33 from falling off the elastic member 34 or from being tilted when being actuated by the transition piece 2 during the use of the rocker switch.

Referring to fig. 7, the base 1 is provided with a second limiting member 12 for limiting the second tilting plate 33 to move away from the elastic member 34. The second limiting member 12 is used to limit the moving amount of the second tilting plate 33 in the thickness direction of the second tilting plate 33, so as to prevent the second tilting plate from being separated from the elastic member 34 by an excessive elastic force, and even from being separated from the installation position of the second tilting plate on the base 1.

In some embodiments of the present application, as shown in fig. 7, a first stopper 331 may be disposed on the second tilting plate 33, and the first stopper 331 protrudes from a side wall of the second tilting plate 33 in the width direction; the second position-limiting member 12 includes a hook 121, and the hook 121 is used for hooking the first position-limiting member 331 on a side of the second tilting plate 33 away from the elastic member 34.

As shown in fig. 7, the second tilting plate 33 has two side walls in the width direction, and the two side walls are respectively opposite to or in contact with the at least two positioning members 11. The first limiting member 331 may be, for example, a limiting shaft, the limiting shaft extends from at least one side wall in the width direction, and when the second tilting plate 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, so as to achieve the purpose of limiting the movement amount of the second tilting plate 33 in the thickness direction. Meanwhile, due to the hook structure of the hook 121, the moving amount of the second rocker 33 may also be limited in the length direction.

In other embodiments of the present application, as shown in fig. 8, the second limiting member 12 may include a latch 122, the latch 122 is located on a side of the second tilting plate 33 away from the elastic member 34, and there is an overlapping area between an orthographic projection of the latch 122 on the bottom wall 14 of the base 1 and an orthographic projection of the second tilting plate 33 on the bottom wall 14 of the base 1. Therefore, when the second tilting plate 33 is moved away from the elastic member 34 by the elastic force provided by the elastic member 34, the second tilting plate 33 is stopped by the catch 122, so as to limit the moving amount of the second tilting plate 33 in the thickness direction.

When the second position-limiting member 12 includes the hook 121 and the buckle 122, the hook 121 and the buckle 122 respectively correspond to two opposite ends of the second tilting plate 33. Exemplarily, as shown in fig. 7, one end of the second tilting plate 33 is connected with a limiting shaft and corresponds to the hook 121; the other end of the second tilting plate 33 corresponds to the buckle 122, and the hook 121 and the buckle 122 are located at the same height on the base 1, so that when the second tilting plate 33 is moved in a direction away from the elastic member 34 by the elastic force provided by the elastic member 34, the two ends of the second tilting plate 33 respectively abut against the hook 121 and the buckle 122, and therefore the two ends of the second tilting plate 33 are uniformly stressed and still keep a state parallel to the bottom wall 14 of the base 1, and the tilting and dropping are not easy to occur. In a possible case, when the rocker switch is in an on state, both ends of the second rocker 33 respectively abut against the hook 121 and the catch 122.

It should be noted that at least one of the hook 121 and the catch 122 has elasticity to facilitate the assembly of the second rocker 33. Use buckle 122 to have elasticity as an example, at the in-process that second wane 33 entered into the installation position on base 1, buckle 122 can dodge second wane 33 under the exogenic action to be convenient for the smooth entering of second wane 33, but on the direction of withdrawing from of second wane 33, buckle 122 can not dodge, but play and block and spacing effect.

As shown in fig. 8, the surface of the latch 122 facing away from the second rocker 33 is a slope, and the slope of the slope is closer to the bottom wall 14 of the base 1 and closer to the middle position of the second rocker 33. This ramp helps the second rocker 33 to move smoothly into the mounting position on the base 1 during assembly.

Alternatively, the surface of the latch 122 facing the second tilting plate 33 may be parallel to the bottom wall 14 of the base 1, so that the surface may act as a stop when the second tilting plate 33 is moved away from the elastic member 34 by the elastic force provided by the elastic member 34.

In the present embodiment, the first abutting portion 21 and the second abutting portion 22 have the same type of structure, and the third abutting portion 31 has a structure adapted thereto. For example, the first abutting portion 21 and the second abutting portion 22 are one of a concave portion and a convex portion, and the third abutting portion 31 is the other of the concave portion and the convex portion. Referring to fig. 10, the first abutting portion 21 and the second abutting portion 22 are both concave portions, and the third abutting portion 31 is a convex portion. Generally, the form of the mating of the projections and recesses is relatively more stable.

Referring to fig. 1, 11 and 12, in some embodiments of the present application, the rocker switch further comprises a pressure plate 5 and a button 6; the pressure plate 5 is assembled in the accommodating cavity of the base 1, the rocker component 3 and the wiring terminal component 4 are both positioned between the pressure plate 5 and the bottom wall 14 of the base 1, and the transition piece 2 is rotatably connected on the pressure plate 5; a button 6 is attached to the transition piece 2 on the side remote from the pressure plate 5.

The user may press a button to toggle the rocker switch between the on state and the off state. As shown in fig. 11, when the rocker switch is in the on state, the button 6 abuts against one side of the base 1, and the vertex of the curved surface of the third abutting portion 31 abuts against the vertex of the curved surface of the first abutting portion 21, wherein the vertex of the curved surface is the lowest point on the curved surface corresponding to the concave portion or the highest point on the curved surface corresponding to the convex portion. As shown in fig. 12, when the rocker switch is in the off state, the push button 6 abuts against the other side of the base 1, and the curved apex of the third abutting portion 31 abuts against the curved apex of the second abutting portion 22.

In some embodiments of the present application, as shown in fig. 13, the first abutting portion 21 corresponds to a first positioning angle which is 1 to 3 times of the flip angle of the push button 6, and the first positioning angle is an included angle between a perpendicular line from the vertex of the curved surface of the first abutting portion 21 to the rotation axis of the transition piece 2 and the center line of the push button 6; and/or the angle of a second positioning angle corresponding to the second abutting part 22 is 1-3 times of the angle of the flip angle of the button 6, and the second positioning angle is an included angle between a perpendicular line from the vertex of the curved surface of the second abutting part 22 to the rotation axis of the transition piece 2 and the center line of the button 6.

For convenience of description, in fig. 13, the flip angle of the push button 6 is denoted by "θ", the first positioning angle corresponding to the first contact portion 21 is denoted by "α", and the second positioning angle corresponding to the second contact portion 22 is denoted by "β". Meanwhile, in the embodiment of the present application, the center line of the push button 6 is a center line that passes through the push button 6 in the thickness direction of the push button 6 and is indicated by a chain line between the first positioning angle α and the second positioning angle β in fig. 13.

Wherein the first positioning angle α and the second positioning angle β may be the same or different. However, in general, the degree of turning of the push button 6 in the on state and the off state needs to be kept uniform. To achieve this, it is possible to design the axis of rotation of the push button 6 to pass through the centre line of the push button 6. Meanwhile, based on the structure of the rocker switch provided by the embodiment of the application, and the curved vertex of the third abutting part 31 abuts against the curved vertex of the first abutting part 21 in the on state, and the curved vertex of the third abutting part 31 abuts against the curved vertex of the second abutting part 22 in the off state, the first positioning angle α can be designed to be equal to the second positioning angle β, so that the rotation angles of the transition piece 2 in the on state and the off state are the same, the turning degrees of the button 6 in the on state and the off state are ensured to be consistent, and the turning angles are all θ.

In some embodiments, the first positioning angle α is 2 times the angle of the flip angle θ and the second positioning angle β is 2 times the angle of the flip angle θ.

Based on the structure of the rocker switch provided by the embodiment of the application, an isosceles triangle can be formed between the rotation center of the button and two ends of the button, the base angle of the isosceles triangle is the turnover angle theta of the button 6, the outer angle of the vertex angle of the isosceles triangle is the rotation angle corresponding to the button and the transition piece in the on state and the off state, and the rotation angle is 2 theta. Therefore, the angles of the first positioning angle α and the second positioning angle β are equal to 2 times the angle of the flip angle θ of the push button 6, i.e., α = β =2 θ, and thus the relationship between the positions of the curved surface vertexes of the first abutting portion 21 and the second abutting portion 22 and the degree of flip of the push button 6 is defined, enabling precise control of the flip angle θ of the push button 6.

In one example, as shown in fig. 13 and 14, the flip angle θ of the 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 curved surface of the first abutting portion 21 is 106 °, the angle corresponding to the curvature of the curved surface of the second abutting portion 22 is 130 °, the angle of the transition angle between the first abutting portion 21 and the second abutting portion 22 is 120 °, and the angle corresponding to the curvature of the curved surface of the third abutting portion 31 is 103 °. The angle tolerance of the above angle can be set according to the requirement, for example, 1 °, 2 °, 5 °, 10 °, and the like.

In embodiments of the present application, the transition piece 2 and the terminal block assembly 4 may be located on the same side of the paddle assembly 3 or may be located on opposite sides of the paddle assembly 3. Wherein, in the first case, when the transition piece 2 and the second connection piece 422 are located on the same side of the rocker assembly 3, the first abutment 21 is further away from said rocker assembly 3 than the second abutment 22; in the second case, when the transition piece 2 and the second connection piece 422 are located on opposite sides of the rocker assembly 3, the first abutment 21 is closer to the rocker assembly 3 than the second abutment 22.

wherein gamma is a first inclination angle,

and theta is the second inclination angle, theta is the flip angle of the push button 6. The first inclination angle is an inclination angle corresponding to the slope of the orthographic projection of the side wall of the first abutting part 21 on the first side on a first plane, the second inclination angle is an inclination angle corresponding to the slope of the orthographic projection of the side wall of the second abutting part 22 on the first plane, and the first plane is a plane perpendicular to the rotation axis of the transition piece 2; when the first abutting portion 21 and the second abutting portion 22 are both recessed portions, the first side is a side away from the second terminal assembly 42; when the first abutting portion 21 and the second abutting portion 22 are both projecting portions, the first side is a side close to the second terminal assembly 42.

In the second case, when the transition piece 2 and the second terminal assembly 42 are located on two opposite sides of the rocker assembly 3, the first inclination angle corresponding to the first abutting portion 21 and the second inclination angle corresponding to the second abutting portion 22 satisfy the following relationship:

wherein, gamma is a first inclination angle,

and theta is the second inclination angle, theta is the flip angle of the push button 6. The first inclination angle is an inclination angle corresponding to the inclination of the orthographic projection of the side wall of the first abutting part 21 on the first plane, the second inclination angle is an inclination angle corresponding to the inclination of the orthographic projection of the side wall of the second abutting part 22 on the first plane, and the first plane is a plane perpendicular to the rotation axis of the transition piece 2; when the first abutting portion 21 and the second abutting portion 22 are both concave portions, the first side is a side far away from the second terminal assembly 42 (for example, the second contact 423); when the first abutting portion 21 and the second abutting portion 22 are both convex portions, the first side is a side close to the second terminal assembly 42 (e.g., the second contact 423).

When the first and second tilting angles satisfy the above-described relationship, it can be ensured that the second rocker 33 is in the tilted state and the contact point on the second rocker 33 is separated from the second contact point 423 when the rocker switch is in the off state.

In summary, in the rocker switch provided in the embodiment of the present application, the transition piece 2 is an integrally formed structure, and compared with the transition piece 2 in the related art, the assembly of the swing piece assembly or the pin spring assembly is not required, and the swing piece assembly or the pin spring assembly is prevented from falling off during the assembly, thereby facilitating the realization of automatic assembly, reducing the assembly workload and the cost, and improving the working efficiency. Simultaneously, because transition piece 2 supports all the time and leans on third butt portion 31 of wane subassembly 3 in this structure, therefore the wane atress is more balanced, and the contact between contact on the wane and the connection piece that corresponds is more firm, has avoided because of the phenomenon of wane spring ablation silver point, has effectively promoted switching performance.
