[0039] Reference Figure 2-Figure 5 , is an embodiment of the micro switch assembly of the present utility model.
[0040] The micro switch assembly includes a waterproof housing 200 and a micro switch 100 .
[0041] The waterproof housing 200 is an integrated structure consisting of a first housing 210, a second housing 220, and a connecting portion 230. By bending the connecting portion 230, the first housing 210 and the second housing 220 can be snapped together to form a housing structure with a mounting cavity.
[0042] The micro switch 100 includes a switch body 110 and a transmission component 120 , wherein the switch body 110 is disposed in the mounting cavity, and the transmission component 120 is at least partially located outside the waterproof housing 200 to facilitate external operation to trigger the switch body 110 to operate.
[0043] The above-mentioned micro switch assembly avoids the additional parts and screws required for the traditional U-shaped combined waterproof structure through the integrated waterproof housing 200 structure, reduces the installation steps and improves production efficiency. At the same time, the switch body 110 is completely wrapped in the waterproof housing 200, achieving all-round waterproof protection, ensuring that condensation water or external water droplets will not enter the interior of the micro switch 100, further improving the safety and reliability of the product.
[0044] In this embodiment, raised waterproof ribs 211 are provided on the inner side of the sidewalls of the first housing 210. During installation, the sidewalls of the second housing 220 are inserted between the sidewalls of the first housing 210 and the waterproof ribs 211. The waterproof ribs 211 form a tight fit with the sidewalls of the first and second housings 210, 220, effectively preventing moisture from penetrating through the joints between the housings, further enhancing the waterproof performance of the waterproof housing 200 and ensuring the safety and reliability of the micro switch 100.
[0045] See also Figure 4 In this embodiment, multiple U-shaped or C-shaped snap grooves 212 extend downwardly along the sidewalls of the first housing 210, while multiple undercuts 221 are correspondingly provided on the sidewalls of the second housing 220. The undercuts 221 engage the snap grooves 212, achieving a stable connection between the first housing 210 and the second housing 220.
[0046] The snap-fit groove 212, as part of the sidewall of the first housing 210, features a simple design and high elasticity, facilitating snap-fit engagement with the undercut 221. To enhance connection stability, at least one snap-fit groove 212 is provided on each side of the first housing 210. Replacing traditional screw fastening with a snap-fit structure significantly simplifies installation and improves assembly efficiency.
[0047] In another embodiment, a snap groove may be provided on the side wall of the first housing 210 to form a snap groove portion for snapping and engaging with the undercut portion.
[0048] In this embodiment, a limiting structure is further provided within the waterproof housing 200 to limit the displacement of the switch body 110 within the housing. This limiting structure ensures that the micro switch 100 remains in a fixed position within the waterproof housing 200, preventing displacement due to vibration or other external forces, thereby ensuring the stability of the micro switch 100.
[0049] Specifically, if Figure 2and 3 As shown, the limiting structure includes positioning posts 213 / 224 and positioning holes 111. The positioning posts 213 and 224 are respectively provided on the first housing 210 and the second housing 220, while the positioning holes 111 are correspondingly provided on both sides of the switch body 110. When the switch body 110 is installed in the waterproof housing 200, the switch body 110 is sandwiched between the first housing 210 and the second housing 220. That is, the two sides of the switch body 110 abut against the inner walls of the first housing 210 and the second housing 220, respectively. At the same time, the positioning posts 213 / 224 are inserted into the positioning holes 111, forming a limiting fit that can limit the movement of the switch body 110 within the waterproof housing 200.
[0050] The positioning structure ensures the precise positioning of the switch body 110 within the waterproof housing 200, preventing functional failures due to positional deviations. The interaction between the positioning post and the positioning hole 111 effectively limits and secures the micro switch 100 during installation, ensuring its stability and safety during use.
[0051] In other embodiments, the limiting structure includes limiting ribs 225 disposed on the inner side of the second housing 220. The switch body 110 can be pre-installed within the limiting space enclosed by the limiting ribs 225 before being engaged with the first housing 210. In other embodiments, the limiting ribs 225 can be provided together with the positioning post structure to provide dual limiting for the switch body 110. The provision of the limiting ribs 225 provides additional structural support, effectively preventing radial or axial movement of the switch body 110, and further enhancing the fixing effect of the switch body 110.
[0052] In addition, the limiting ribs 225 further enhance the overall structural strength of the waterproof housing.
[0053] In this embodiment, the waterproof housing 200 is provided with a wire opening 222. This opening is used to connect the wires of the microswitch 100, allowing them to pass smoothly through the waterproof housing 200 and connect to the external circuit. The wire opening 222 can be located on the side or bottom of the waterproof housing 200 to fully meet waterproof requirements. In this embodiment, the wire opening 222 is located on the second housing 220.
[0054] To facilitate the installation of the microswitch assembly, a mounting and fixing portion 223 is further provided on the first housing 210 and / or the second housing 220. Threaded holes are provided on the mounting and fixing portion 223, and the waterproof housing 200 can be fixed to the corresponding position of the device using fasteners such as screws. By adding the mounting and fixing portion 223 to the waterproof housing 200, the microswitch assembly can be conveniently installed in various household appliances, especially in application scenarios that require waterproofing. This design improves the convenience and reliability of installation, and at the same time, the fastening of the threaded holes improves the stability of the microswitch assembly. In this embodiment, two mounting and fixing portions 223 are provided on the second housing 220, and the two mounting and fixing portions 223 are respectively provided on both sides of the second housing.
[0055] In this embodiment, the transmission component 120 of the microswitch 100 specifically comprises a reed. One end of the reed is fixed to the switch body 110, and the other end extends outside the waterproof housing 200 (the waterproof housing 200 has a specific opening or notch at this location to allow the reed to be partially exposed). When an external object or force is applied to the exposed portion of the reed, the reed is triggered to deform, and the microswitch 100 is switched between the open and closed states through a mechanical linkage mechanism. Specifically, a button is provided on the switch body 110, and pressing the button with the reed activates the microswitch 100.

Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
