Description

Technical Field

[0001] This utility model relates to the field of electronic switch technology, and in particular to a push-button switch. Background Technology

[0002] Pushbutton switches are widely used in automotive roof light signal control, automotive window operation, flashlight beam control, and other fields. Existing pushbutton switches typically process their terminal components by first stamping the terminals, then injection molding the terminals and body together, and finally bending the surface-mount leads. After processing, these surface-mount leads are completely exposed without protection, creating a risk of deformation during subsequent processes. This can lead to defects such as solder joint defects (cold solder joints) during SMT reflow soldering. Furthermore, existing pushbutton switches usually require pressing the button twice to switch the on / off signal, which is not user-friendly.

[0003] Therefore, there is an urgent need for a push-button switch to solve the above-mentioned technical problems. Utility Model Content

[0004] Based on the above, the purpose of this utility model is to provide a push button switch that can effectively protect the surface pins of the terminal assembly, ensure the surface flatness, and prevent surface pin deformation during each process flow; at the same time, it improves the ease of operation of the push button switch.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A push-button switch, comprising:

[0007] The outer shell has multiple limiting ribs spaced circumferentially on its inner wall, a limiting groove between adjacent limiting ribs, and a first inclined surface on the bottom surface of the limiting ribs.

[0008] The body and the terminal assembly include a common terminal, a first terminal, and a second terminal. Each of the common terminal, the first terminal, and the second terminal has bent contact leads. The body and the terminal assembly are integrally molded by injection molding. Each contact lead extends outward from the body. A protective block protrudes outward from the body at a position corresponding to each contact lead, and the contact leads are disposed on the protective block. The body is connected to the outer shell, and a mounting cavity is formed between the body and the outer shell.

[0009] A push handle is pressably disposed in the mounting cavity, the top of the push handle extends out of the outer shell, and the bottom end of the push handle is provided with a first ratchet tooth;

[0010] A switching component is movably disposed in the mounting cavity. The outer periphery of the switching component is provided with a second ratchet tooth that can mesh with the first ratchet tooth. The switching component is also provided with a slider. The slider protrudes radially from the outside of the second ratchet tooth. The slider can slide along the limiting groove. The top of the slider is provided with a second inclined surface. The second inclined surface and the first inclined surface form a wedge mechanism.

[0011] A first reset element is disposed between the switching element and the push handle;

[0012] A rubber transfer plate is movably connected to the switching component, and the rubber transfer plate can rotate with the switching component;

[0013] The second reset component is disposed between the adhesive transfer sheet and the switching component;

[0014] A brush is fixed to the bottom of the adhesive transfer sheet. The bottom of the brush has two contacts, one of which contacts the common terminal and the other contact contacts the first terminal or the second terminal.

[0015] In some possible implementations, both the first terminal and the second terminal are C-shaped and intersecting each other. The first terminal has a first contact end and a second contact end, and the second terminal has a third contact end and a fourth contact end. The first contact end, the third contact end, the second contact end, and the fourth contact end are arranged sequentially at intervals.

[0016] In some possible implementations, the common terminal has two faceted pins located on a first side of the body; the first terminal has one faceted pin, the second terminal has one faceted pin, and the faceted pins of the first and second terminals are located on a second side of the body; the first and second sides are arranged opposite to each other.

[0017] In some possible implementations, the two surface pins located on the same side of the body are respectively disposed on two separate protective blocks; or, the two surface pins located on the same side of the body are jointly disposed on a single protective block.

[0018] In some possible implementations, the inner wall of the housing is uniformly provided with eight limiting ribs and eight limiting grooves; pressing down the handle causes the switching member to rotate 22.5 degrees, the slider to rotate below the limiting ribs, and the brush switches from being connected to the first terminal to being connected to the second terminal, or the brush switches from being connected to the second terminal to being connected to the first terminal; releasing the handle causes the second reset member to cause the switching member to continue rotating 22.5 degrees in the same direction, the slider rotates into the limiting groove, and the brush's connection signal remains unchanged.

[0019] In some possible implementations, a guide claw is also provided on the outer periphery of the handle, the guide claw being located radially outside the first ratchet tooth and the slider; the limiting groove includes an alternately distributed first limiting groove and a second limiting groove, the depth of the first limiting groove being greater than the depth of the second limiting groove, and the guide claw being slidably disposed within the first limiting groove.

[0020] In some possible implementations, the handle has a connecting shaft at its center, the connecting shaft extending into and connecting to the switching element; the switching element has an inner cylinder and an outer cylinder, the opening of the inner cylinder facing the handle, and the first reset element installed in the inner cylinder; the opening of the outer cylinder facing the rubber switch, and the second reset element installed in the outer cylinder; the second ratchet tooth and the slider are disposed outside the outer cylinder.

[0021] In some possible implementations, the transfer sheet is provided with a connecting rod, the top of the connecting rod is provided with a snap-fit ​​part, the switching member is provided with a connecting groove, the connecting rod is movably disposed in the connecting groove along the axial direction of the switching member, and the snap-fit ​​part snaps into the connecting groove.

[0022] In some possible implementations, the bottom of the adhesive transfer sheet is fixed to the brush by riveting or snap-fitting.

[0023] In some possible implementations, a bracket is also included, which is snapped onto the housing and engaged with the body to secure the housing and the body.

[0024] The beneficial effects of this utility model are:

[0025] The push-button switch provided by this utility model first uses a stamping process to form a terminal assembly and bends each surface pin of the terminal assembly. Then, the terminal assembly and the body are integrally formed by injection molding. The body and each surface pin have a protective block protruding outward at the corresponding position. The surface pins are set on the protective block. The protective block can effectively protect the surface pins, ensure the flatness of the surface, and prevent the surface pins from deforming during each process flow, thereby improving the processing quality of the product in the SMT reflow soldering process.

[0026] In its initial state, the slider of the button switch is located in the limiting groove. When the handle is pressed down, the slider moves down along the limiting groove. Through the engagement of the first and second ratchet teeth, the switching element rotates at a certain angle, and the slider rotates to below the limiting rib. At this time, the brush switches the conduction signal once. Then, the handle is released, and the handle resets under the action of the first reset element. Driven by the second reset element and with the engagement of the first and second inclined surfaces, the switching element continues to rotate in the same direction at a certain angle. At this time, the slider rotates to another adjacent limiting groove. During this reset process, the conduction signal of the brush remains unchanged. In other words, the button switch of this utility model can switch the conduction signal between the brush and the terminal assembly simply by pressing the handle; and the handle resets when the handle is released, and the conduction signal between the brush and the terminal assembly remains unchanged. Therefore, this button switch is simple, convenient, and reliable to operate. Attached Figure Description

[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0047] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0050] like Figures 1 to 8 As shown, this embodiment provides a push-button switch, including a housing 1, a body 2, a terminal assembly 3, a push handle 4, a switching element 5, a first reset element 6, a rubber transfer piece 7, a second reset element 8, a brush 9, and a bracket 10. The housing 1 has an inner cavity extending through both ends. Multiple limiting ribs 11 are spaced circumferentially along the inner wall of the housing 1, and limiting grooves 12 are provided between adjacent limiting ribs 11. Each limiting rib 11 has a first inclined surface 111 on its bottom surface. Specifically, the extending directions of the limiting ribs 11 and the limiting grooves 12 are parallel to the axis of the housing 1. The body 2 is connected to the housing 1 to form a mounting cavity. The push handle 4, switching element 5, rubber transfer piece 7, and brush 9 are sequentially arranged within the mounting cavity along the axial direction of the housing 1. The bracket 10 is fastened to the housing 1, and the bracket 10 is snapped into the body 2, thus achieving a secure connection between the housing 1 and the body 2. This design facilitates assembly and ensures reliable fixation. In this embodiment, the body 2 is made of plastic, and the terminal assembly 3 is made of conductive metal. The body 2 and the terminal assembly 3 are integrally formed by injection molding. Specifically, the terminal assembly 3 includes a common terminal 31, a first terminal 32, and a second terminal 33. During processing, the common terminal 31, the first terminal 32, and the second terminal 33 are first formed by stamping, and then the edges of the common terminal 31, the first terminal 32, and the second terminal 33 are bent to form surface-mount leads 34. The entire terminal assembly 3 is then injection molded as an insert with the body 2. This arrangement avoids the inconvenience of bending the surface-mount leads 34 after injection molding and improves the bending accuracy of the surface-mount leads 34. Furthermore, after the body 2 and the terminal assembly 3 are injection molded as a single unit, each surface-mount lead 34 extends beyond the body 2, and a protective block 21 protrudes outward from the corresponding position of the body 2 and each surface-mount lead 34, with the surface-mount leads 34 positioned on the protective block 21. In this embodiment, the protective block 21 effectively protects the surface-mount leads 34, ensuring a smooth surface finish and preventing deformation of the surface-mount leads 34 during various process flows, thus improving the processing quality of the product in the SMT reflow soldering process.

[0051] The handle 4 is the operating component of the push-button switch. The handle 4 is pressable within the mounting cavity along the axial direction of the housing 1. The top of the handle 4 extends out of the housing 1, and the bottom end of the handle 4 has a first ratchet tooth 41. The switching component 5 is rotatably disposed within the mounting cavity and can slide along the axial direction of the housing 1 within the mounting cavity. A second ratchet tooth 51 is provided on the outer periphery of one end of the switching component 5. The first ratchet tooth 41 meshes with the second ratchet tooth 51, driving the switching component 5 to rotate. The switching component 5 also has a slider 52, which protrudes radially from the outside of the second ratchet tooth 51. The slider 52 slides in conjunction with the limiting groove 12. The top of the slider 52 has a second inclined surface 521, which forms a wedge mechanism with the first inclined surface 111. A first reset component 6 is disposed between the switching component 5 and the handle 4. Preferably, the first reset component 6 is a compression spring. A rubber rotating piece 7 is movably connected to the switching component 5 and can rotate with the rotation of the switching component 5. The second reset element 8 is disposed between the rubber transfer plate 7 and the switching element 5. Preferably, the second reset element 8 is a compression spring, and the elastic force of the second reset element 8 is greater than the elastic force of the first reset element 6. The brush 9 is fixed to the bottom of the rubber transfer plate 7, and the rotation of the rubber transfer plate 7 can drive the brush 9 to rotate. Specifically, the bottom of the rubber transfer plate 7 and the brush 9 can be fixed by riveting or by snap-fitting, which is simple to assemble and reliable to connect. The bottom of the brush 9 is provided with two contacts 91, one of which contacts the common terminal 31, and the other contact 91 contacts the first terminal 32 or the second terminal 33 to realize the output of the button switch signal.

[0052] The working principle of this embodiment is as follows:

[0053] In the initial state, the slider 52 is located in the limiting groove 12. When the handle 4 is pressed down, the handle 4 presses the first reset member 6 and acts on the switching member 5. The switching member 5 moves down, causing the slider 52 to move down along the limiting groove 12 (at this time, the switching member 5 cannot rotate due to the restriction of the limiting groove 12). At the same time, the downward movement of the switching member 5 also presses the second reset member 8. When the slider 52 moves down to the point of disengaging from the limiting groove 12, the switching member 5 rotates at a certain angle under the cooperation of the first ratchet tooth 41 and the second ratchet tooth 51, and the slider 52 rotates to below the limiting rib 11. Simultaneously, the adhesive transfer piece 7 and the brush 9 rotate with the switching component 5, causing the button switch to switch the output signal once. Then, the handle 4 is released, and the handle 4 resets under the action of the first reset component 6. The switching component 5 continues to rotate in the same direction at a certain angle under the drive of the second reset component 8 and the cooperation of the first inclined surface 111 and the second inclined surface 521. At this time, the slider 52 rotates into another adjacent limiting groove 12. During this reset process, the adhesive transfer piece 7 and the brush 9 rotate with the switching component 5, but the conduction signal between the brush 9 and the terminal assembly 3 remains unchanged. In other words, in this embodiment, the button switch only requires pressing the handle 4 to switch the conduction signal between the brush 9 and the terminal assembly 3; and releasing the handle 4 resets the handle 4, and the conduction signal between the brush 9 and the terminal assembly 3 remains unchanged. Therefore, the button switch only requires pressing the handle 4 once to complete the signal switching, which is simple, convenient, and reliable in use.

[0054] Optionally, in this embodiment, the common terminal 31 has two surface pins 34, which are located on the first side of the body 2; the first terminal 32 has one surface pin 34, and the second terminal 33 has one surface pin 34, which are located on the second side of the body 2; the first side and the second side are arranged opposite to each other. This arrangement allows the surface pins 34 to be located on both sides of the body 2, facilitating connection with external devices. Furthermore, the two surface pins 34 located on the same side of the body 2 can be arranged one-to-one on two independent protective blocks 21, which helps to reduce the weight of the push-button switch; or, the two surface pins 34 located on the same side of the body 2 can be arranged together on a single protective block 21, which simplifies the structure of the injection mold and facilitates processing.

[0055] Optionally, both the first terminal 32 and the second terminal 33 are C-shaped and arranged intersecting each other. The first terminal 32 has a first contact end 321 and a second contact end 322 for connecting with the contact 91 of the brush 9. The second terminal 33 has a third contact end 331 and a fourth contact end 332 for connecting with the contact 91 of the brush 9. The first contact end 321, the third contact end 331, the second contact end 322, and the fourth contact end 332 are arranged in sequence at intervals. With this configuration, when the handle 4 is pressed, one contact 91 of the brush 9 rotates from the first contact end 321 to the third contact end 331, thereby disconnecting from the first terminal 32 and connecting with the second terminal 33, completing one signal switching. When the handle 4 is reset, the contact 91 still moves on the third contact end 331, maintaining connection with the second terminal 33. When the handle 4 is pressed again, the contact 91 rotates from the third contact end 331 to the second contact end 322, thereby disconnecting from the second terminal 33 and connecting with the first terminal 32, completing another signal switching. When the handle 4 is reset again, the contact 91 still moves on the second contact end 322, maintaining connection with the first terminal 32, and so on.

[0056] Specifically, in this embodiment, the inner wall of the outer casing 1 is uniformly provided with eight limiting ribs 11 and eight limiting grooves 12. With this configuration, when the handle 4 is pressed down, the switching member 5 rotates 22.5 degrees clockwise, the slider 52 rotates to below the limiting rib 11, and the brush 9 switches from being connected to the first terminal 32 to being connected to the second terminal 33, or vice versa. When the handle 4 is released, the first reset member 6 resets the handle 4, and the second reset member 8 causes the switching member 5 to continue rotating 22.5 degrees clockwise, the slider 52 rotates into another limiting groove 12, and the connection signal of the brush 9 remains unchanged. In this entire cycle of pressing down and returning, the rotation angle of the switching member 5 is 45°.

[0057] Furthermore, a guide claw 42 is provided on the outer periphery of the handle 4, and the guide claw 42 is located radially outside the first ratchet tooth 41 and the slider 52. The limiting groove 12 includes alternating first limiting grooves 121 and second limiting grooves 122, the depth of the first limiting groove 121 is greater than the depth of the second limiting groove 122, and the guide claw 42 is slidably disposed within the first limiting groove 121. In this embodiment, by providing the guide claw 42, the movement of the handle 4 can be guided, making the pressing and returning actions of the handle 4 more precise and the operation more reliable.

[0058] Specifically, the switching component 5 in this embodiment has an inner cylinder 53 and an outer cylinder 54. The opening of the inner cylinder 53 faces the handle 4, and the first reset component 6 is installed in the inner cylinder 53. The opening of the outer cylinder 54 faces the rubber rotating piece 7, and the second reset component 8 is installed in the outer cylinder 54. The second ratchet tooth 51 and the slider 52 are disposed on the outer periphery of the opening end of the outer cylinder 54. Further, a connecting shaft 43 is provided in the middle of the handle 4. The first reset component 6 is sleeved on the connecting shaft 43. The connecting shaft 43 passes through the inner cylinder 53 and is connected to the riveting piece. This can prevent the handle 4 from detaching from the switching component 5, and at the same time, the connecting shaft 43 can serve as the rotation shaft of the switching component 5.

[0059] Furthermore, to achieve a reliable connection between the switching component 5 and the transfer sheet 7, in this embodiment, a connecting rod 71 is provided on the transfer sheet 7, and a snap-fit ​​part 711 is provided at the top of the connecting rod 71. A connecting groove 55 is provided on the switching component 5, and the connecting rod 71 is slidably disposed in the connecting groove 55 along the axial direction of the switching component 5, and is snapped into the connecting groove 55 by the snap-fit ​​part 711. In this embodiment, by providing the connecting rod 71, the switching component 5 can drive the transfer sheet 7 to rotate synchronously when it rotates; by providing the snap-fit ​​part 711, the switching component 5 and the transfer sheet 7 can be prevented from detaching.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
