Description

Technical Field

[0001] The utility model relates to the field of micro switches, in particular to a high-current micro switch with good sealing performance. Background Art

[0002] A micro switch is a contact mechanism with a tiny contact spacing and a quick-action mechanism, which uses a specified stroke and a specified force to perform a switching action. Because the contact spacing of the switch is relatively small, it is called a micro switch, also known as a sensitive switch. Most of the existing micro switch housings are rectangular as a whole, and the two lead-out terminals usually extend from the length direction of the housing, and the button is usually installed at the joint of the detachable housing. The disadvantage of the above structure is that on the one hand, the waterproof performance is poor and it is not easy to waterproof; on the other hand, because the terminals extend from the length direction of the housing, and some micro switches have certain requirements for length restrictions, the terminals will compress the internal space of the housing when waterproofing, affecting the layout of the internal components, thereby limiting the current passing through the micro switch and reducing the user experience. Utility Model Content

[0003] In view of this, the utility model provides a high-current micro switch which can obtain good sealing performance without changing the length of the micro switch housing.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A high-current micro switch with good sealing performance comprises a shell, a first terminal and a second terminal arranged in the shell, an elastic conductive member connecting the first terminal and the second terminal, and a button for driving the elastic conductive member to act; the shell comprises a hollow shell with an opening, and an end cover covering the opening, the end cover is a side surface of the shell with the largest area, the wiring terminal of the first terminal and the wiring terminal of the second terminal are both bent and led out from the end cover, and the end cover is coated with a waterproof rubber layer; the button can be movably plugged into the hollow shell, and a sealing rubber sleeve is provided on the button.

[0006] In the above technical solution, the shell is split into a hollow shell and an end cover, and the button is set on the hollow shell instead of the joint between the hollow cavity and the end cover. The first terminal and the second terminal are both led out from the end cover. When sealing, it is only necessary to apply a waterproof adhesive layer on the end cover and set a sealing rubber sleeve on the button. The waterproof structure is set on the outside of the shell, so while improving the sealing of the micro switch, it also reduces the difficulty of sealing and facilitates sealing processing. The waterproof adhesive layer and the sealing rubber sleeve work together to effectively prevent moisture, dust and other impurities from entering the switch, thereby ensuring the stable operation of the switch.

[0007] In addition, waterproof structures such as waterproof rubber layers and sealing rubber sleeves are arranged on the outside of the shell and do not occupy the internal space of the shell, so that the internal space of the shell can be arranged with larger conductive components or terminals, which can withstand higher currents without overheating or damage, and can effectively adapt to electronic equipment and systems that need to process high-power signals.

[0008] Optionally, in a possible implementation, a socket is provided on the hollow shell, the button is inserted into the socket, and a limiting boss is provided at one end of the button located in the hollow shell, and the limiting boss can abut against the end of the socket.

[0009] In the above technical solution, the button is directly plugged into the jack of the hollow shell, and the user can intuitively find and press the button to perform the required operation, which improves the user experience and makes the operation more convenient. The design of the limit boss ensures that the button will not accidentally fall off after being inserted into the jack. When the button is pressed, the limit boss can abut against the end of the jack, thereby providing stable support for the button. In addition, the limit boss can also block the jack to further improve the sealing of the micro switch.

[0010] Optionally, in a possible implementation, a notch is provided on the limiting boss, the notch divides the limiting boss into two parts, and the notch extends to the button.

[0011] In the above technical solution, the notch is provided to facilitate squeezing the limiting boss into the socket. By providing a notch on the limiting boss, it is divided into two parts, and a certain elastic space is formed between the two parts, so that when the button is inserted into or pulled out of the socket, the two parts of the limiting boss can undergo a slight deformation, thereby increasing the adaptability between the button and the socket and reducing the difficulty of assembly.

[0012] Optionally, in a possible implementation, a card platform is provided on the hollow shell, the card platform is sleeved on the outer periphery of the button, a first card slot is provided on the card platform, a second card slot is provided on the button, one end of the sealing rubber sleeve is sleeved in the first card slot, and the other end is sleeved in the second card slot.

[0013] In the above technical solution, the provision of the first card slot and the second card slot can not only facilitate the installation of the sealing rubber ring, but also improve the sealing stability of the sealing rubber ring, effectively preventing dust, moisture or other pollutants from entering the interior of the switch. In addition, since the sealing rubber sleeve is directly sleeved in the card slots of the card platform and the button, no additional fixings or adhesives are required, which greatly simplifies the assembly process.

[0014] Optionally, in a possible implementation, the card platform is a “T”-shaped structure, and the “T”-shaped structure cooperates with the hollow shell to form the first card slot.

[0015] In the above technical solution, the design of the "T"-shaped card platform provides stable support for the button, so that the button has a larger support area, thereby improving the pressing stability of the button. In addition, the first card slot formed by the "T"-shaped card platform and the hollow shell can ensure that the waterproof rubber sleeve can be installed quickly and stably. It only needs to be sleeved in the card slot, and it is not easy to shake or fall off.

[0016] Optionally, in a possible implementation manner, opposite ends of the sealing rubber sleeve are respectively provided with a first snap-in socket and a second snap-in socket matching the first snap-in slot and the second snap-in slot.

[0017] In the above technical solution, the design of the first bayonet and the second bayonet ensures the tight combination between the sealing sleeve and the hollow shell and the button, thereby further enhancing the sealing effect. In addition, since the first bayonet and the second bayonet match the first slot and the second slot respectively, the sealing sleeve can be easily fixed in the correct position without too much adjustment during installation, which not only improves the installation accuracy, but also reduces the error rate during the installation process.

[0018] Optionally, in a possible implementation, the elastic conductive member includes a swing member movably connected to the first terminal, a slice movably connected to the swing member, and a spring for driving the slice to reset, and the button can drive the swing member to rotate relative to the first terminal.

[0019] In the above technical solution, the swinging member in the elastic conductive member can flexibly rotate relative to the first terminal, ensuring that the pressure can be smoothly transmitted when the button is pressed and the conductive state can be accurately controlled. At the same time, the reset function of the spring ensures that the slice can quickly return to the initial position after the button is released, ensuring reliable switching of the conductive state.

[0020] Optionally, in a possible implementation, a flange is provided on the inner edge of the hollow shell, and the end cover can abut against the flange; a plurality of clamping holes are also provided in the hollow shell, and a plurality of clamping columns matching the clamping holes are provided on the end cover.

[0021] In the above technical solution, the design of the flange provides a clear abutment surface for the end cover. When the end cover and the hollow shell are closed, the end cover can fit tightly on the flange, effectively reducing the gap between the two, thereby enhancing the sealing of the overall structure. And when the end cover and the hollow shell are closed, the clamping column can be accurately inserted into the clamping hole to form a stable connection structure, thereby improving the connection stability between the end cover and the hollow shell.

[0022] Optionally, in a possible implementation manner, a plurality of mounting holes are provided on a side of the hollow shell relative to the end cover.

[0023] In the above technical solution, the mounting holes can facilitate the installation of the micro switch on different devices, and can also provide convenience for the expansion of the equipment. By installing different accessories or modules on these mounting holes, the expansion or upgrade of the equipment functions can be easily achieved to meet the diverse needs of users.

[0024] Optionally, in a possible implementation, the waterproof adhesive layer is coated on the entire surface of the end cap, or the waterproof adhesive layer is coated on the connection between the end cap and the hollow shell, and the connection between the end cap and the first terminal and the second terminal.

[0025] In the above technical solution, the waterproof adhesive layer not only has a waterproof function, but also can protect the end cap from corrosion, wear and other damage to a certain extent, thereby extending the service life of the device and improving the durability of the device. The coverage of the waterproof adhesive layer can be selectively controlled according to actual use requirements to achieve the best use effect.

Specifically, the shell 1 is a rectangular parallelepiped structure as a whole, and the opening is arranged on the long and wide surface of the hollow shell 11, that is, the side with the largest area. The wiring terminal of the first terminal 2 and the wiring terminal of the second terminal 3 are both perpendicular to the end cover 12.

[0038] In this embodiment, the housing 1 is split into a hollow housing 11 and an end cover 12, and the button 5 is arranged on the hollow housing 11 rather than at the joint between the hollow cavity and the end cover 12. The first terminal 2 and the second terminal 3 are both led out from the end cover 12. When sealing, it is only necessary to apply a waterproof adhesive layer on the end cover 12 and to cover the button 5 with a sealing rubber sleeve 6. The waterproof structure is arranged outside the housing 1, so while improving the sealing of the micro switch, it also reduces the difficulty of sealing and facilitates sealing processing. The waterproof adhesive layer and the sealing rubber sleeve 6 work together to effectively prevent moisture, dust and other impurities from entering the interior of the switch, thereby ensuring the stable operation of the switch.

[0039] In addition, waterproof structures such as the waterproof rubber layer and the sealing rubber sleeve 6 are arranged on the outside of the shell 1 and do not occupy the internal space of the shell 1, so that the internal space of the shell 1 can be arranged with larger conductive components or terminals, which can withstand higher currents without overheating or damage, and can effectively adapt to electronic equipment and systems that need to process high-power signals.

[0040] Please refer to Figure 2 In this embodiment, a socket 111 is provided on the hollow shell 11, and the button 5 is inserted into the socket 111, and a limiting boss 51 is provided at one end of the button 5 located in the hollow shell 11, and the limiting boss 51 can abut against the end of the socket 111. Specifically, a part of the button 5 extends into the interior of the hollow shell 11 and abuts against the elastic conductive member 4, and a part extends to the outside of the central control shell. The button 5 matches the aperture of the socket 111, and the limiting boss 51 protrudes from the outer edge of the button 5. The limiting boss 51 can be an elastic rubber structure, which is pressed into the socket 111 by extrusion.

[0041] By directly inserting the button 5 into the socket 111 of the hollow housing 11, the user can intuitively find and press the button 5 to perform the desired operation, thereby improving the user experience and making the operation more convenient. The design of the limiting boss 51 ensures that the button 5 will not accidentally fall off after being inserted into the socket 111. When the button 5 is pressed, the limiting boss 51 can abut against the end of the socket 111, thereby providing stable support for the button 5. In addition, the limiting boss 51 can also block the socket 111 to further improve the sealing of the micro switch.

[0042] Please continue to refer to Figure 2 In this embodiment, a notch 52 is provided on the limiting boss 51, and the notch 52 divides the limiting boss 51 into two parts, and the notch 52 extends to the button 5. It should be noted that the limiting boss 51 can be an integrally formed structure with the button 5, and the materials of both are plastic.

[0043] The notch 52 of the present embodiment is provided to facilitate squeezing the limiting boss 51 into the socket 111. By providing the notch 52 on the limiting boss 51, it is divided into two parts, and a certain elastic space is formed between the two parts, so that when the button 5 is inserted into or pulled out of the socket 111, the two parts of the limiting boss 51 can undergo a slight deformation, thereby increasing the adaptability between the button 5 and the socket 111 and reducing the difficulty of assembly.

[0044] Please continue to refer to Figure 2 In this embodiment, a card table 7 is provided on the hollow shell 11, and the card table 7 is sleeved on the outer periphery of the button 5. A first card slot 71 is provided on the card table 7, and a second card slot 53 is provided on the button 5. One end of the sealing rubber sleeve 6 is sleeved in the first card slot 71, and the other end is sleeved in the second card slot 53. It can be understood that the card table 7 is set at the jack 111, and the jack 111 extends to the card table 7. When the button 5 is installed, it passes through the card table 7 and the hollow shell 11 in sequence. In addition, the card table 7 is a "T"-shaped structure, and the "T"-shaped structure cooperates with the hollow shell 11 to form the first card slot 71.

[0045] The provision of the first card slot 71 and the second card slot 53 in this embodiment can not only facilitate the installation of the sealing rubber ring, but also improve the sealing stability of the sealing rubber ring, and effectively prevent dust, moisture or other pollutants from entering the interior of the switch. In addition, since the sealing rubber sleeve 6 is directly sleeved in the card slots of the card platform 7 and the button 5, no additional fixings or adhesives are required, which greatly simplifies the assembly process.

[0046] Specifically, the design of the "T"-shaped card platform 7 provides a stable support for the button 5, so that the button 5 has a larger support area, thereby improving the pressing stability of the button 5. In addition, the first card slot 71 formed by the "T"-shaped card platform 7 and the hollow shell 11 can ensure that the waterproof rubber sleeve is installed quickly and stably. It is only necessary to sleeve the sealing rubber sleeve 6 into the card slot, and it is not easy to shake or fall off.

[0047] Please continue to refer to Figure 2 In this embodiment, the opposite ends of the sealing rubber sleeve 6 are respectively provided with a first bayonet (not shown in the figure) and a second bayonet 61 matching the first bayonet 71 and the second bayonet 53. The sealing rubber sleeve 6 has a "U"-shaped notch at one end close to the first bayonet.

[0048] The design of the first bayonet and the second bayonet 61 ensures a tight fit between the sealing rubber sleeve 6 and the hollow shell 11 and the button 5, thereby further enhancing the sealing effect. In addition, since the first bayonet and the second bayonet 61 match the first slot 71 and the second slot 53 respectively, the sealing rubber sleeve 6 can be easily fixed in the correct position without much adjustment during installation, which not only improves the installation accuracy but also reduces the error rate during the installation process.

[0049] Please refer to Figure 3 In this embodiment, the elastic conductive member 4 includes a swing member 41 movably connected to the first terminal 2, a slice 42 movably connected to the swing member 41, and a spring 43 driving the slice 42 to reset. The button 5 can drive the swing member 41 to rotate relative to the first terminal 2. The swing member 41 in the elastic conductive member 4 can flexibly rotate relative to the first terminal 2, ensuring that the pressure can be smoothly transmitted when the button 5 is pressed, and the conductive state can be accurately controlled. At the same time, the reset function of the spring 43 ensures that the slice 42 can quickly return to the initial position after the button 5 is released, ensuring reliable switching of the conductive state.

[0050] It should be noted that the elastic conductive member 4 is a commonly used structure of existing micro switches. The internal structure of the micro switch in this embodiment is roughly the same as that of the existing micro switch. The main difference lies in the wiring terminals of the first terminal 2 and the second terminal 3. Therefore, the specific principles and layout are not repeated here.

[0052] The design of the flange 112 of this embodiment provides a clear abutment surface for the end cover 12. When the end cover 12 and the hollow shell 11 are closed, the end cover 12 can fit tightly on the flange 112, effectively reducing the gap between the two, thereby enhancing the sealing of the overall structure. And when the end cover 12 and the hollow shell 11 are closed, the clamping column 121 can be accurately inserted into the clamping hole 113 to form a stable connection structure, thereby improving the connection stability between the end cover 12 and the hollow shell 11.

[0053] Please refer to Figure 5 In this embodiment, a plurality of mounting holes 114 are provided on one side of the hollow housing 11 relative to the end cover 12. The mounting holes 114 can be used to conveniently mount the micro switch on different devices, and can also provide convenience for the expansion of the device. By installing different accessories or modules on these mounting holes 114, the expansion or upgrade of the device function can be easily achieved to meet the diverse needs of users.

[0054] In this embodiment, the waterproof adhesive layer is coated on the entire surface of the end cap 12 , or the waterproof adhesive layer is coated on the connection between the end cap 12 and the hollow shell 11 , and the connection between the end cap 12 and the first terminal 2 and the second terminal 3 .

[0055] The waterproof adhesive layer not only has a waterproof function, but also can protect the end cap 12 from corrosion, wear and other damage to a certain extent, thereby extending the service life of the device and improving the durability of the device. The coverage of the waterproof adhesive layer can be selectively controlled according to actual use requirements to achieve the best use effect.
