Description

Technical Field

[0001] The embodiments of the present application relate to the field of electrical equipment, and particularly to a switch. Background Art

[0002] As a control component for controlling the on / off of a circuit, a switch is an indispensable part of a circuit system. With the progress of technology and the improvement of people's requirements for product performance, there are more requirements for the structural stability, operation convenience, occupied space, etc. of the switch.

[0003] Among the existing switches, the ultra-thin switch can hide most of its structure below the installation base surface such as the wall surface, and only expose a very thin part of the structure. It has the advantages of small occupied space, not easy to accumulate dust, and convenient operation, and has become one of the most commonly used switches.

[0004] However, the existing ultra-thin switches often adopt a metal frame structure. Although it is strong and durable, its cost is relatively high and its weight is relatively large, which is not conducive to the lightweight and cost control of the product. Therefore, how to reduce its weight and cost while ensuring the structural strength of the switch has become a technical problem to be solved. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a switch. The frame of the switch is a solid plastic frame, and concave portions are provided on the outer surface of the frame, so that the overall structure of the frame has pre-deformation treatment. The whole frame is not easy to shrink during injection molding, the frame has sufficient strength to support the pressing operation received by the pressing component, and moreover, the frame is lighter in weight and lower in cost.

[0006] In one aspect of the embodiments of the present application, a switch is provided. The switch includes a frame, a pressing component, and a conductive component. The pressing component and the conductive component are installed on the frame. The frame is a plastic solid frame, and concave portions are provided on the outer surface of the frame. The pressing component includes a movable button and a transmission member, and the conductive component includes a movable moving contact. The button is connected to the moving contact through the transmission member, so that the moving contact moves synchronously with the button to connect or disconnect the current loop corresponding to the pressing component.

[0007] The frame of the switch has sufficient strength to support the pressing operation received by the pressing component, its strength is reliable, and its weight and cost are lower. Moreover, the concave portions are equivalent to pre-deforming the frame, which can make the shrinkage process of the frame during injection molding within a controllable range, and the overall size of the frame will not be overly reduced, so that the formed frame has sufficient strength. At the same time, the shrinkage process of the frame during injection molding is controllable, which can make the outer shape of the frame smoother and ensure its aesthetic degree.

[0008] In an optional manner, the inner concave surface of the concave portion is smoothly connected to the outer surface of the frame.

[0009] This method can make the concave part connect more smoothly with the outer surface of the frame. The outer surface of the frame after injection molding is also smoother and neater, and the overall structure is more beautiful.

[0010] In an alternative method, the frame includes a mounting portion and an embedding portion. The mounting portion has opposite first and second surfaces. The button is arranged on the first surface, and the second surface is used to abut against the mounting base surface of the mounting switch; the embedding portion is arranged on the second surface and is used to be embedded into the mounting base surface for hiding.

[0011] In this method, the frame has a mounting portion and an embedding portion, so that only a part of the switch is exposed after installation, occupying less space and being more beautiful. Moreover, there is less exposed part on the switch, making it not easy to accumulate dust.

[0012] In an alternative method, the concave part includes a first groove, and the first groove is arranged on the first surface.

[0013] In this method, when the frame is injection molded, the first surface of the frame will shrink conforming to the first groove, which can make the shrinkage process of the first surface controllable, avoid excessive shrinkage of the first surface, and ensure the size and strength of the first surface.

[0014] In an alternative method, the side wall and the bottom surface of the first groove are smoothly connected.

[0015] In this method, the inner surfaces of the first groove transition smoothly, making the concave surface of the first groove smoother and avoiding excessive shrinkage during the injection molding of the frame structure.

[0016] In an alternative method, a cavity is arranged in the embedding portion, the opening of the cavity is located at the bottom surface of the first groove, and the conductive component is installed in the cavity.

[0017] In this method, the opening of the cavity of the embedding portion is opposite to the button, the overall structure is more compact, and the pressing component and the conductive component can be inserted into the cavity from the first surface, making the assembly of the switch more convenient.

[0018] In an alternative method, the first surface is an arched surface, and a fixing structure is arranged at the arched position of the first surface, and the fixing structure is used to fixedly install the switch on the mounting base surface.

[0019] In this method, the solid frame structure between the first surface and the second surface set as the arched surface forms an arched beam, which can make the frame stronger and also save materials. Moreover, the arched surface can reserve enough moving space for the button, making it more convenient to operate.

[0020] In an alternative method, the maximum distance between the first surface and the second surface is less than or equal to 6 mm, so that when the switch is installed on the mounting base surface, the height of the exposed part of the switch is less than or equal to 6 mm.

[0021] In this method, the distance between the first surface and the second surface is less than or equal to 6 millimeters, which can make the thickness of the exposed part of the switch installed on the installation base surface smaller, so that the switch is an ultra-thin switch, reducing the occupied space of the switch and avoiding dust accumulation on the switch.

[0022] In an optional method, the concave part includes a second groove, and the second groove is arranged on the second surface.

[0023] In this method, when the frame is injection molded, the second surface of the frame will shrink conforming to the second groove, which can make the shrinkage process of the second surface controllable, avoid excessive shrinkage of the second surface, and ensure the size and strength of the second surface.

[0024] In an optional method, the second groove is a grid-shaped groove.

[0025] In this method, the grid-shaped groove can prevent the second surface from excessive shrinkage when the frame is injection molded, and the rib-like structures between the grooves in the grid-shaped groove can further strengthen the strength of the frame.

[0026] In the switch provided by the embodiment of the present application, the frame of the switch is a solid plastic frame, which makes the frame have sufficient strength while reducing its weight and cost. Moreover, an inner concave part is arranged on the outer surface of the frame, and this inner concave part is equivalent to pre-deforming the frame. When the frame is injection molded, the outer shape of the frame will shrink conforming to the shape of the inner concave part, making its shrinkage process within a controllable range. The overall size of the frame will not be excessively reduced, so that the formed frame has sufficient strength to support the weights of the pressing component and the conductive component, and also enables the frame to reliably support the pressing operation received by the pressing component. At the same time, the shrinkage process of the frame during injection molding is controllable, which can make the outer shape of the frame smoother, avoid generating redundant pits, can avoid process defects during manufacturing, and can also ensure its aesthetic degree.

[0048] The switch provided by the present application is as Figure 1 shown Figure 1 and is an exploded view of a switch provided by an embodiment of the present application. Among them, the switch includes a frame 10, a pressing assembly 20, and a conductive assembly 30.

[0049] The frame 10 is a frame structure that provides an installation space and support for the pressing assembly 20 and the conductive assembly 30. The frame 10 is used to connect to an installation base surface such as a connecting wall to install the switch on the installation base surface. Sufficient installation space is reserved in the frame 10 to accommodate the pressing assembly 20 and the conductive assembly 30. The installation space may specifically be composed of structures such as cavities, struts, and card slots, and no specific limitation is made here.

[0050] The frame 10 has sufficient strength to support the pressing assembly 20 and the conductive assembly 30 with weight. At the same time, the strength of the frame 10 needs to ensure that the frame 10 can support the pressing operation received by the pressing assembly 20, that is, the frame 10 can withstand a certain pressing force without being damaged.

[0051] In this embodiment, the frame 10 is a solid plastic frame. The material of the frame 10 can be selected from plastic materials with high strength, wear resistance, and good insulation performance, such as acrylonitrile-butadiene-styrene copolymer (ABS) or polycarbonate (PC), etc.

[0052] The frame 10 is set as a solid plastic frame, which can ensure that while the frame 10 has sufficient strength, the overall structural weight of the frame 10 is smaller and the cost is lower, so as to reduce its weight and cost while ensuring the strength of the switch structure.

[0053] An inner concave portion 11 is provided on the outer surface of the frame 10, specifically as Figure 2 and Figure 3 shown. Figure 2 This is a sectional view of the switch with hidden buttons from the first perspective according to the embodiment of the present application. Figure 3 This is a sectional view of the switch with hidden buttons from the second perspective according to the embodiment of the present application.

[0054] The inner concave portion 11 is an inner concave structure provided on the outer surface of the frame 10. The inner concave portion 11 can be a groove, a trench, a pit, etc., which is not limited herein. The inner concave portion 11 can be provided on a certain outer surface of the frame 10 or on multiple outer surfaces.

[0055] The setting of the inner concave portion 11 is equivalent to pre-deforming the frame 10. When the frame 10 is injection molded, the outer shape of the frame 10 will shrink in accordance with the inner concave portion 11, so that the shrinkage process and the shape after shrinkage are within a controllable range, the frame 10 will not shrink excessively, and the overall size of the frame 10 will not decrease, thus ensuring that the frame 10 has sufficient strength to support the weights of the pressing component 20 and the conductive component 30, and also enabling the frame 10 to reliably support the pressing operation received by the pressing component 20.

[0056] The inner concave surface of the inner concave portion 11 can be smoothly connected to the outer surface of the frame 10, that is, the inner concave surface of the inner concave portion 11 and the outer surface of the frame 10 have a gradual and smooth transition. Exemplarily, a chamfer, an inclined surface, etc. can be provided at the connection position between the inner concave surface of the inner concave portion 11 and the outer surface of the frame 10. This way can make the connection between the inner concave portion 11 and the outer surface of the frame 10 smoother, the outer surface of the frame 10 after injection molding is also flatter and neater, and the overall structure is more beautiful.

[0057] The pressing component 20 and the conductive component 30 are installed on the frame 10. The pressing component 20 is used to respond to the user's pressing operation and synchronize the pressing operation into the current loop, so that the current loop is turned on and off corresponding to the pressing operation.

[0058] Such as Figure 1 and Figure 3As shown in the figure, the pressing component 20 specifically includes a movable button 21 and a transmission member 22. The button 21 is movably arranged on the frame 10, and its exposed part is for the user to press. The button 21 can be set in a structure of being pressed in and out, that is, the on-off of the current loop corresponding to the pressing component 20 is controlled by the pressing-in operation and the pressing-out operation of the button 21. The button 21 can also be set as a lever-type flip button, that is, the on-off of the current loop corresponding to the pressing component 20 is controlled by pressing the opposite ends of the button 21. And, the flipping angle of the flip button can be further set, for example, the flipping angle of the flip button can be less than or equal to 3 degrees.

[0059] The button 21 can specifically be set in a long strip plate-like structure, or can be set in a protruding button-like structure, or can be set in a pressable oval structure, etc., and no specific limitation is made here.

[0060] The transmission member 22 can be made of metal or high-strength plastic to make it have sufficient rigidity and durability. The transmission member 22 is connected to both the button 21 and the conductive component 30 at the same time to transfer the movement of the button 21 to the conductive component 30, thereby controlling the on-off of the current loop in the conductive component 30.

[0061] The transmission member 22 can specifically be a single body structure that can move synchronously with the button 21, or can be composed of a combination of multiple structures that play a transmission role. The transmission member 22 can specifically include a lever structure, a gear structure, elastic members such as springs, a transmission rod structure, etc., and no specific limitation is made here.

[0062] The button 21 and the transmission member 22 are arranged in pairs, and there can be multiple pairs of the button 21 and the transmission member 22 to control the on-off of different current loops. When there are multiple pairs of the button 21 and the transmission member 22, the multiple buttons 21 can be arranged side by side at intervals, and the multiple transmission members 22 can also be arranged side by side at intervals.

[0063] The conductive component 30 is composed of multiple conductive parts, and the conductive component 30 can be conductively connected to the incoming power wire and the outgoing power to form a current loop. The current loop corresponding to the pressing component 20 refers to the current loop whose on-off state can be controlled by the pressing component 20. When there are multiple buttons 21 in the pressing component 20, multiple current loops are also correspondingly set in the conductive component 30.

[0064] Such as Figure 1 and Figure 3 As shown in the figure, the conductive component 30 specifically includes a movable moving contact piece 31 and a fixedly arranged static contact piece 32 and other conductive parts. The moving contact piece 31 and the static contact piece 32 are arranged opposite to each other, forming a moving contact point and a static contact point of the current loop respectively. When the moving contact piece 31 contacts the static contact piece 32, the current loop is turned on. When the moving contact piece 31 is separated from the static contact piece 32, the current loop is turned off.

[0065] The button 21 is connected to the moving contact piece 31 through the transmission piece 22, so that the moving contact piece 31 moves synchronously with the button 21 to connect or disconnect the current loop corresponding to the pressing assembly 20. That is to say, the movement of the moving contact piece 31 is controlled by the button 21. When the button 21 is pressed to the energized state, the transmission piece 22 will move the moving contact piece 31 to the position where it contacts the static contact piece 32, thus connecting the current loop corresponding to the button 21. When the button 21 is pressed to the de-energized state, the transmission piece 22 will move the moving contact piece 31 to the position where it separates from the static contact piece 32, thus disconnecting the current loop corresponding to the button 21.

[0066] In this embodiment, the switch can be an embedded ultra-thin switch. The specific implementation manner can be as Figure 3 and Figure 4 shown, Figure 4 which is the overall structural schematic diagram of the switch involved in the embodiment of the present application. The frame 10 includes a mounting portion 12 and an embedding portion 13. The mounting portion 12 has opposite first surface 121 and second surface 122. The button 21 is arranged on the first surface 121, and the second surface 122 is used to abut against the mounting base surface where the switch is installed. The embedding portion 13 is arranged on the second surface 122 and is used to be embedded into the mounting base surface for hiding.

[0067] In this way, the mounting portion 12 of the frame 10 is used to abut against the mounting base surface for installation, and the embedding portion 13 is used to provide an installation space for the pressing assembly 20 and the conductive assembly 30. When the mounting portion 12 is installed on the mounting base surface, the embedding portion 13 is embedded into the mounting base surface for hiding.

[0068] The button 21 of the pressing assembly 20 is arranged on the first surface 121 of the mounting portion 12. The button 21 can either abut against the first surface 121 or be partially embedded into the first surface 121. When the switch is installed on the mounting base surface, the second surface 122 opposite to the first surface 121 abuts against the mounting base surface, and the button 21 faces away from the mounting base surface, so as to facilitate the user to perform the pressing operation.

[0069] The embedding portion 13 can be a protruding structure protruding from the second surface 122, and the embedding portion 13 can be specifically located at the middle position of the second surface 122, so that the embedding portion 13 and the mounting portion 12 form a tower-like structure. A cavity 131 is arranged inside the embedding portion 13 to place the conductive assembly 30. And a wiring port can be arranged on the embedding portion 13, and the incoming power wire and the outgoing power wire can extend into the wiring port to be connected to the conductive assembly 30 to form a current loop.

[0070] An embedding space corresponding to the embedding portion 13 is provided on the installation base surface. When installing the switch, the embedding portion 13 only needs to be aligned with the embedding space, and the second surface 122 of the installation portion 12 is abutted against the installation base surface, so that the embedding portion 13 can be naturally embedded into the installation base surface. The power input wire and the power output wire can extend into the embedding portion 13 from the installation base surface, so as to form a current loop by connecting with the conductive component 30. For example, when the installation base surface is a wall surface, the power input wire and the power output wire can extend into the embedding portion 13 from the wall body, so as to form a current loop by connecting with the conductive component 30.

[0071] In this way, the frame 10 has the installation portion 12 and the embedding portion 13, so that only a part of the switch is exposed after installation, occupying less space and being more beautiful. Moreover, since there is less exposed part on the switch, it is not easy for the switch to accumulate dust.

[0072] The areas of the first surface 121 and the second surface 122 of the installation portion 12 can be set to be relatively large, so that when the user presses the button 21, the first surface 121 and the second surface 122 of the frame 10 can withstand sufficient pressing force. In order to further ensure the strength of the first surface 121 and the second surface 122 and avoid excessive shrinkage during injection molding, concave portions 11 can be provided on the first surface 121 and / or the second surface 122.

[0073] When the concave portion 11 is provided on the first surface 121, a feasible implementation manner can be as Figure 2 and Figure 3 shown. The concave portion 11 includes a first groove 111, and the first groove 111 is provided on the first surface 121.

[0074] In this way, during the injection molding of the frame 10, the first surface 121 of the frame 10 will shrink along with the first groove 111, which can make the shrinkage process of the first surface 121 controllable, avoid excessive shrinkage of the first surface 121, and ensure the size and strength of the first surface 121.

[0075] In this way, the first groove 111 can be smoothly connected to the first surface 121, and the side wall of the first groove 111 can also be smoothly connected to the bottom surface of the first groove 111, so that the inner surfaces of the first groove 111 are smoothly transitioned, making the concave surface of the first groove 111 smoother and avoiding excessive shrinkage during the injection molding of the frame 10 structure. There are many ways to smoothly connect the side wall and the bottom surface. For example, it can be connected by a fillet, or the side wall can be set as an inclined surface connected to the bottom surface to achieve the purpose of smooth connection.

[0076] The first groove 111 can be set as a groove with a circular opening or a groove with a square opening. In a specific embodiment, the opening size of the first groove 111 can correspond to the overall area of the first surface 121. For example, when the switch is an 86-type switch, that is, the length and width of the front projection view of the switch are both 86 millimeters, the length and width of the first surface 121 can both be set to 86 millimeters, and accordingly, the opening of the first groove 111 can be set to a structure with an overall area slightly smaller than the area of the first surface 121. For example, the opening of the first groove 111 can be a square with a length and width of 75 millimeters.

[0077] The button 21 of the pressing component 20 faces the first surface 121. The conductive component 30 is installed in the embedding part 13, and the transmission part 22 of the pressing component 20 is connected to the conductive component 30. To facilitate the installation of the pressing component 20 and the conductive component 30 on the frame 10 and to facilitate the connection between the pressing component 20 and the conductive component 30, the opening of the cavity 131 of the embedding part 13 can face the button 21.

[0078] Exemplarily, a feasible way is as Figure 3 shown. A cavity 131 is provided in the embedding part 13, and the opening of the cavity 131 is located at the bottom surface of the first groove 111. The conductive component 30 is installed in the cavity 131.

[0079] In this way, the opening of the cavity 131 of the embedding part 13 faces the button 21, the overall structure is more compact, and the pressing component 20 and the conductive component 30 can be inserted into the cavity 131 from the first surface 121, making the switch assembly more convenient.

[0080] In this embodiment, the solid frame part between the first surface 121 and the second surface 122 forms a support beam, which can support the pressing force received by the pressing component 20. This support beam structure can be set as a rectangular structure or an arched structure.

[0081] Exemplarily, in an optional way as Figure 1 、 Figure 3 and Figure 4 shown, the first surface 121 is an arched surface, and a fixing structure 14 is provided at the arched position of the first surface 121. The fixing structure 14 is used to fixedly install the switch on the installation base surface.

[0082] In this way, the first surface 121 is an arched surface, which can be composed of two inclined surfaces with an included angle or can be set as an arched curved surface. The shape of the second surface 122 corresponds to the shape of the installation base surface. For example, when the installation base surface is a plane, the second surface 122 is also set as a plane convenient for abutting against the installation base surface.

[0083] There are many specific forms of the fixing structure 14. For example, it can be set as a pair of mounting holes, a mounting shaft, a clamping structure, etc. When the fixing structure 14 is set as a pair of mounting holes, the switch can be fixed on the mounting base surface by screws inserted into the mounting holes. The mounting holes should be kept at a certain distance from the edge of the frame 10. For example, the distance between the mounting holes and the edge of the frame 10 is more than 8 mm to ensure the strength of the frame 10 and enable the switch to be reliably fixed on the mounting base surface.

[0084] In this way, the solid frame structure between the first surface 121 and the second surface 122 set as an arched surface forms an arched beam, which can make the frame 10 stronger and also save materials. Moreover, the arched surface can reserve enough space for the button 21 to move, making it more convenient to operate.

[0085] There are many ways to set the distance between the first surface 121 and the second surface 122. In a feasible implementation, the maximum distance between the first surface 121 and the second surface 122 is less than or equal to 6 mm, so that when the switch is mounted on the mounting base surface, the height of the exposed part of the switch is less than or equal to 6 mm.

[0086] In this way, the distance between the first surface 121 and the second surface 122 is less than or equal to 6 mm, which can make the thickness of the exposed part of the switch mounted on the mounting base surface smaller, so that the switch is an ultra-thin switch, reducing the occupied space of the switch and avoiding dust accumulation on the switch.

[0087] When the concave part 11 is provided on the second surface 122, a feasible implementation can be as Figure 2 and Figure 3 shown. The concave part 11 includes a second groove 112, and the second groove 112 is provided on the second surface 122.

[0088] In this way, when the frame 10 is injection-molded, the second surface 122 of the frame 10 will shrink along with the second groove 112, which can make the shrinkage process of the second surface 122 controllable, avoid excessive shrinkage of the second surface 122, and ensure the size and strength of the second surface 122.

[0089] There are also many structural forms of the second groove 112. An optional way can be as Figure 5 shown, Figure 5 which is the front view of the second surface of the switch involved in the embodiment of the present application. The second groove 112 can be set as a grid-shaped groove. In this way, the grid-shaped groove can avoid excessive shrinkage of the second surface 122 when the frame 10 is injection-molded, and the rib-like structure between the grooves in the grid-shaped groove can further strengthen the strength of the frame 10.

[0090] In summary, in the switch described above, the frame of the switch is a solid plastic frame, which reduces its weight and cost while ensuring sufficient strength of the frame. Moreover, a concave portion is provided on the outer surface of the frame, which is equivalent to pre-deforming the frame. When the frame is injection-molded, the outer shape of the frame will shrink conforming to the shape of the concave portion, making its shrinkage process within a controllable range, and the overall size of the frame will not shrink excessively. Thus, the formed frame has sufficient strength to support the weights of the pressing component and the conductive component, and can also reliably support the pressing operations received by the pressing component. At the same time, the shrinkage process during the injection molding of the frame is controllable, which can make the outer shape of the frame smoother, avoid generating unnecessary pits, can avoid process defects during manufacturing, and can also ensure its aesthetic degree.
