Description

Technical Field

[0001] This utility model belongs to the field of waterproof switch technology, specifically relating to a rotary push-button waterproof switch. Background Technology

[0002] A push-button switch is a switch that uses a button to actuate a transmission mechanism, causing the moving contact to connect or disconnect with the stationary contact, thus switching the circuit. Push-button switches are simple in structure and widely used control electrical appliances. In electrical automatic control circuits, they are used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

[0003] For example, in motorcycle applications, multiple push-button switches can be used to turn functions such as turning lights on and off. However, these push-button switches are not sealed to the housing. When it rains, rainwater may seep into the motorcycle through the gaps between the switch and the housing, come into contact with the stationary contacts on the motorcycle's base plate, and cause a short circuit, thus affecting the motorcycle's operation. Utility Model Content

[0004] This utility model discloses a rotary press-type waterproof switch, which aims to solve the technical problem in the prior art where the non-waterproof press switch may affect the use of motorcycles.

[0005] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0006] A rotary push-button waterproof switch includes a base plate, on which a stationary contact and a protective cover are disposed. A moving contact passes through the protective cover and can contact the stationary contact. A reset device is disposed between the moving contact and the protective cover to limit and guide the moving contact. The reset device includes a limiting platform disposed above the protective cover. The limiting platform has a frustum structure and a second through hole for the moving contact to pass through. A reset spring is disposed around the limiting platform and the moving contact. One end of the reset spring abuts against the protective cover, and the other end abuts against the moving contact.

[0007] By adopting this technical solution, a protective cover is installed between the moving contact and the stationary contact to protect both of them. This prevents rainwater from adhering to the moving or stationary contact during rain, which could cause a short circuit when they come into contact, thus protecting the circuit.

[0008] A limiting platform and a return spring fitted onto the limiting platform are installed between the moving contact and the protective cover. The return spring provides the power for the moving contact to reset, making it convenient to use. The limiting platform is designed as a frustum of a cone, and the return spring is also designed as a frustum of a cone fitted onto the outside of the limiting platform. This compensates for the travel of the moving contact during the pressing process, allowing the moving and stationary contacts to make contact within a shorter pressing distance, improving the smoothness and feel of the device during use. Finally, the limiting platform provides support for the return spring during pressing, preventing deformation of the return spring during use and improving its stability, thereby enhancing the stability of the entire device during operation.

[0009] The protective cover includes a top plate and three side plates attached to the top plate. The limiting platform is disposed on the top plate. The height difference between the top of the uncompressed reset spring and the top of the limiting platform is 0.5-1.5cm.

[0010] By adopting this technical solution, the protective cover is designed with an opening on the side, which allows for timely repair of the stationary contact when problems occur, and also facilitates the installation of the stationary contact during manufacturing.

[0011] The distance between the top of the return spring and the top of the limit platform is the travel distance of the moving contact. This distance ensures the tactile feel of pressing the moving and stationary contacts.

[0012] The moving contact includes a pressing rod that contacts the stationary contact. The pressing rod is connected to a pressing cap that cooperates with the pressing key. One end of the return spring abuts against the protective cover, and the other end abuts against the bottom surface of the pressing cap.

[0013] By adopting this technical solution, the setting of the pressing cap, protective cover, and limiting platform firstly limits the position of the return spring, preventing it from shifting during extension and retraction, thus ensuring the stability of the return spring during use, and consequently ensuring the stability of the entire device during use. Secondly, the setting of the pressing cap improves the tactile feedback of the user pressing the moving contact point, thereby enhancing the user experience of the device during use.

[0014] A sealing device is provided between the moving contact and the second through hole on the limiting platform. The sealing device includes a sealing ring sleeved on the pressing rod, and the sealing ring is slidably connected to the second through hole.

[0015] By adopting this technical solution, the sealing ring prevents rainwater and other substances from entering the protective cover through the gap between the moving contact and the second through hole, thus preventing the stationary contact from getting wet. Therefore, the sealing ring further protects the contact area between the moving and stationary contacts.

[0016] The limiting platform is provided with a flow guiding device, which includes a sliding groove on the limiting platform. The sliding groove communicates with the second through hole. The sealing ring is provided with a slider that cooperates with the sliding groove. The slider has an inclined structure, the top surface of the sealing ring has an arc-shaped structure, and the slider is located at the lowest point of the arc-shaped structure. The bottom of the side wall of the sliding groove is provided with a first flow guiding channel, which is inclined in the limiting platform.

[0017] With this technical solution, when the moving contact slides and contacts the stationary contact, the sealing ring is constantly in contact with the limiting platform. Therefore, rainwater splashed or dripping between the sealing ring and the limiting platform will accumulate there. Thus, by providing an inclined first guide channel on the bottom sidewall of the slide, when the moving contact slides to contact the stationary contact (i.e., reaches the contact stroke), the rainwater accumulated between the sealing ring and the limiting platform will flow from the first guide channel to the top surface of the protective cover, further ensuring the safety of the contact point between the moving and stationary contacts.

[0018] The protective cover is provided with a flow guide groove that cooperates with the first flow guide channel. The flow guide groove is located on the top surface of the protective cover and surrounds the limiting platform. The first flow guide channel is connected to the flow guide groove.

[0019] By adopting this technical solution, the design of the guide channel can divert rainwater entering the limiting platform from the first guide channel into the guide channel, and then divert it to other places, thereby improving the protection effect on the moving and stationary contacts.

[0020] The guide channel is connected to a guide pipe.

[0021] By adopting this technical solution, the rainwater flowing to the protective cover is diverted through the diversion channel to the diversion pipe, which improves the protection effect on the moving and stationary contacts.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] (1) Protective covers and other protective measures are used to protect the contact points between the moving and stationary contacts, preventing short circuits caused by rainwater penetration and effectively protecting the circuit, thus extending the service life of the device. At the same time, limiters are installed to limit the reset spring and protect the moving contacts, ensuring smooth operation of the device.

[0024] (2) The protective cover with side openings is easy to install on the stationary contact and can be repaired when the stationary contact has a problem, which reduces costs.

[0025] (3) The setting of the limiting platform and the pressing cap restricts the position of the reset spring, ensuring the stability of the reset spring during use, and further ensuring the stability of the device during use.

[0026] (4) The sealing ring prevents rainwater from entering the protective cover through the gap between the limiting platform and the pressing rod and coming into contact with the stationary contact, thus further improving the protection effect on the circuit.

[0027] (5) Setting up the first drainage channel and the guide channel can reduce the time that rainwater stays in the limiting platform and reduce the possibility of rainwater seeping in from the contact point between the sealing ring and the pressing rod, thereby further improving the protection effect on the circuit.

[0037] The following is combined with Figures 1-4 This utility model will be described in detail.

[0038] Example 1

[0039] A rotary push-button waterproof switch, such as Figures 1-2 As shown, the device includes a substrate 1, on which a stationary contact 2 and a protective cover 3 are provided. A movable contact 7 passes through the protective cover 3 and can contact the stationary contact 2. A reset device is provided between the movable contact 7 and the protective cover 3 to limit and guide the movable contact 7. The reset device includes a limiting platform 4 disposed above the protective cover 3. The limiting platform 4 has a frustum structure and a second through hole for the movable contact 7 to pass through. A reset spring 5 is sleeved on the limiting platform 4 and the movable contact 7. One end of the reset spring 5 abuts against the protective cover 3, and the other end abuts against the movable contact 7.

[0040] In this embodiment, the substrate 1 is a circuit substrate 1, and the circuit is basically connected to the housing, frame, shell, etc. by bolt connection.

[0041] In this embodiment, the second through hole is integrally formed with the limiting platform 4.

[0042] In this embodiment, the substrate 1 is an aluminum substrate 1, a copper-clad laminate with good heat dissipation properties, consisting of a three-layer structure: a circuit layer (copper foil), an insulating layer, and a metal base layer. The aluminum substrate 1 is used in motorcycle circuits primarily because of its excellent heat dissipation performance, which effectively reduces the temperature of the circuit during operation, thereby improving the circuit's stability and lifespan.

[0043] In this embodiment, the protective cover 3 is made of aluminum alloy and is connected to the substrate 1 by welding.

[0044] In this embodiment, both the moving contact 7 and the stationary contact 2 are made of silver-nickel alloy, and the stationary contact 2 is welded to the substrate 1.

[0045] In this embodiment, the shape of the reset spring 5 is the same as that of the limiting platform 4, both being frustum structures, and the reset spring 5 can be sleeved on the limiting platform 4.

[0046] In this embodiment, one end of the return spring 5 contacts the top of the protective cover 3, and the other end abuts against the moving contact 7, so that the return spring 5 can only extend and retract between the moving contact 7 and the protective cover 3.

[0047] In this embodiment, the return spring 5 is made of stainless steel. Stainless steel has excellent corrosion resistance and high strength, and is suitable for spring applications that require corrosion resistance, such as in humid or corrosive environments.

[0048] In this embodiment, the large end radius of the limiting platform 4 is 3.65mm, the small end radius is 2.75mm, and the height is 2.8mm.

[0049] In this embodiment, the height of the reset spring 5 is 5.48 cm.

[0050] In this embodiment, the protective cover 3 includes a top plate and three side plates of the top plate, the limiting platform 4 is disposed on the top plate, and the height difference between the top of the uncompressed reset spring 5 and the top of the limiting platform 4 is 4.6-5.8cm.

[0051] In this embodiment, the top plate and the three side plates are all integrally formed by welding.

[0052] In this embodiment, the limiting platform 4 is made of the same material as the protective cover 3, and the limiting platform 4 and the protective cover 3 are integrally formed by welding.

[0053] In this embodiment, the moving contact 7 includes a pressing rod that contacts the stationary contact 2. The pressing rod is connected to a pressing cap 701 that cooperates with the pressing key. One end of the return spring 5 abuts against the protective cover 3, and the other end abuts against the bottom surface of the pressing cap 701.

[0054] In this embodiment, both the pressing rod and the pressing button are made of PVC material, and the pressing cap 701 and the pressing rod are integrally formed by bonding.

[0055] In this embodiment, the silver-nickel alloy is welded to the end of the pressing rod away from the pressing cap 701.

[0056] In this embodiment, the diameter of the pressing cap 701 is 6mm, and the diameter of the pressing rod is 4mm.

[0057] In this embodiment, the limiting platform 4 is provided with a second through hole that cooperates with the pressing rod. The pressing rod passes through the second through hole of the limiting platform 4 and the first through hole 301 of the protective cover 3 in sequence before contacting the stationary contact 2.

[0058] In this embodiment, the diameters of the first through hole 301 and the second through hole are equal.

[0059] In this embodiment, the diameter of the first through hole 301 is equal to the diameter of the pressing rod.

[0060] In this embodiment, a sealing device is provided between the moving contact 7 and the second through hole on the limiting platform 4. The sealing device includes a sealing ring 6 sleeved on the pressing rod, and the sealing ring 6 is slidably connected to the second through hole.

[0061] In this embodiment, the pressing rod is provided with an annular groove for installing the sealing ring 6. After the sealing ring 6 is snapped into the annular groove, it can be fixed to the pressing rod by means of adhesive.

[0062] In this embodiment, the outer wall of the sealing ring 6 is in contact with the inner wall of the first through hole 301.

[0063] In this embodiment, the sealing ring 6 is made of stainless steel, which has a high sealing effect and the pressing rod slides smoothly.

[0064] The specific method of using this utility model is as follows:

[0065] Reference Figures 1-2 When in use, this device is initially installed on the base plate 1, inside the frame and housing. An external push button is provided; pressing the moving contact 7 causes it to contact the stationary contact 2, thus completing the circuit. When rainwater enters the frame or housing from between the components, it flows through the limiting platform 4, the telescopic spring, and the protective cover 3, preventing the rainwater from contacting the moving contact 7 or the stationary contact 2, thus preventing a short circuit.

[0066] Some rainwater may also be splashed onto the protective cover 3, but due to the protective function of the protective cover 3, the rainwater will not penetrate to the contact point between the moving contact 7 and the stationary contact 2.

[0067] The remaining rainwater may be splashed after impacting the protective cover 3, or some of the rainwater may directly enter the contact area between the limiting platform 4 and the pressing rod. Due to the setting of the sealing ring 6, this part of the rainwater will accumulate on the top of the sealing ring 6 until the moving contact 7 returns to its original position under the action of the return spring 5. At this time, this part of the accumulated rainwater will move out from the top of the limiting platform 4 along with the movement of the sealing ring 6.

[0068] This device employs a protective cover 3 to protect the contact point between the moving contact 7 and the stationary contact 2, preventing short circuits caused by rainwater penetration and effectively protecting the circuit, thus extending the device's service life. Simultaneously, a limiting platform 4 is installed to limit the return spring 5, protecting the moving contact 7 and ensuring smooth operation of the device.
