Description

Technical Field

[0001] The utility model relates to a switch element, in particular to a switch component which is easy to assemble. Background Art

[0002] A touch switch is an electronic switch element. It is small in appearance and usually wrapped in a plastic shell. It has a precise metal dome structure inside, and the circuit is turned on and off mainly by light pressing. This switch has multiple pins, three of which are common, which can meet different circuit connection requirements. In operation, it only requires a small pressing force to trigger. It is widely used in various electronic devices, such as control panels of electronic toys, calculators and other small devices. Because of its high sensitivity, it can accurately convert the user's operating instructions into electrical signals, thereby helping the device to complete the corresponding function opening, stopping or mode switching operations.

[0003] When the touch switch is sealed with hot glue at the bottom and a sealant is installed at the top, it must be installed from top to bottom. Because the hot glue is at the bottom, if it is installed from bottom to top, the hot glue will flow under the influence of gravity and the sealing effect cannot be guaranteed. This method not only limits the installation direction, but also increases labor costs due to the increase in hot glue materials, sealant procurement, and complicated operation procedures, and the overall processing cost increases significantly. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a switch assembly which is easy to assemble by replacing the sealing method.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a switch assembly that is easy to assemble, including a shell for providing a sealed environment for internal components, the two ends of the shell are respectively a button and a plurality of pins, the plurality of pins have different trigger strokes relative to each other and the plurality of pins are sequentially turned on when the button moves toward the direction of the pins, the shell includes a first sealed shell and a second sealed shell, the first sealed shell is provided with an assembly opening at one end facing the button, and is provided with through holes corresponding to the number of pins for the pins to pass through at one end facing the pins, the second sealed shell is provided with a sleeve opening toward the direction of the pins, the second sealed shell covers the first sealed shell through the sleeve opening and is sleeved from one side of the assembly opening toward the direction of the through holes, the second sealed shell is sleeved outside the first sealed shell and a sealed connection between the two is achieved by snapping.

[0006] The beneficial effect of the utility model is that the switch assembly is applied to the bent pins, and its bottom-up installation method effectively avoids bending the pins after the switch is installed, preventing the bending operation from affecting the switch itself. In addition, the housing is composed of a first and a second sealed housing, and a sealed connection is achieved by a snap-on method. This structure not only simplifies the installation process and improves the assembly efficiency, but also effectively resists the intrusion of external impurities and water vapor due to good sealing performance, ensures the stable operation of internal components, and prolongs the service life of the switch assembly.

[0007] Furthermore, the first sealed shell is a rectangular body, and at least one clip is arranged on each end face of the first sealed shell. Each clip is arranged upwardly and inclined along the sleeve direction of the second sealed shell and forms a clip platform at its end. The second sealed shell is respectively provided with clip grooves matching the clips on each end face of the first sealed shell, and the first sealed shell and the second sealed shell are sealed and fixed by the cooperation between the clips and the clip grooves.

[0008] The first sealed housing is a rectangular body, and each end face is provided with at least one buckle that is inclined upward along the direction of the second sealed housing and forms a buckle platform at the end. The second sealed housing is provided with a buckle groove correspondingly, and the two are sealed and fixed by the buckle and the buckle groove. This not only makes the installation process more convenient, the buckle and the buckle groove are accurately matched, and no complicated debugging is required during installation, which greatly improves the assembly efficiency. Moreover, this tight snap-fitting strengthens the sealing performance, can more effectively block external impurities and water vapor, and fully protect the internal components, ensuring the stable operation of the switch assembly and greatly extending its service life.

[0009] Furthermore, the buckles are all located on one side of the center line of each end surface of the first sealing shell and are arranged close to one side of the penetration hole.

[0010] The buckle is arranged on one side of the center line of each end face of the first sealed housing and close to the side of the penetration hole. During assembly, the second sealed housing can be free from obstruction by the buckle in the initial installation, and can be initially positioned more smoothly, avoiding installation deviation and jamming caused by premature contact with the buckle, significantly reducing the difficulty of assembly and improving assembly efficiency. At the same time, this buckle layout concentrated near the penetration hole can form a key sealing protection around the penetration hole when achieving sealing fixation, effectively preventing foreign matter from invading from the pin penetration hole, further improving the sealing performance, and ensuring the stability of the internal environment of the switch assembly.

[0011] Furthermore, it also includes a cover plate and a conductive part covering the assembly opening, the button is arranged on the cover plate, and a through hole for the button to pass through is arranged on the second sealed shell corresponding to the position of the button; a pressing groove is arranged at one end of the cover plate facing the inside of the first sealed shell, the pressing groove abuts against the conductive part and drives the conductive part to move toward the pin direction when the button drives the cover plate to move.

[0012] A cover plate and a conductive part are newly added to the switch assembly, and a button is arranged on the cover plate. The second sealed shell is provided with a through hole for the button to pass through. At the same time, a pressing groove is provided at one end of the cover plate facing the inside of the first sealed shell, which can form an interference fit with the conductive part. The interference fit effectively prevents the conductive part from accidentally falling out, ensuring that it always maintains a stable connection state during frequent use, greatly improving the connection reliability. Moreover, the stable matching relationship can ensure the conduction effect, avoid abnormal current transmission problems caused by poor contact, and ensure the stability of the electrical performance of the switch assembly. When the button drives the cover plate to move, the pressing groove can accurately drive the conductive part to move toward the pin direction, realizing efficient and stable circuit conduction control, and optimizing the operational response performance of the switch assembly.

[0013] Furthermore, it also includes a dustproof plate fixed on the assembly opening, and a silicone sleeve is provided on the outside of the button at a position corresponding to the button on the dustproof plate.

[0014] A new dustproof plate fixed on the assembly opening and a silicone sleeve covering the button at the corresponding button position play an important role. The dustproof plate is stationary and can effectively prevent external dust, particles and other impurities from directly contacting the cover plate, preventing the cover plate from being damaged by scratches or accumulated dust, thereby extending the service life of the cover plate. In addition, the second sealed housing and the dustproof plate cooperate with each other to build a double protection barrier for the components inside the first sealed housing, greatly reducing the interference and erosion of internal components by external factors, comprehensively ensuring the stable operation of the switch assembly, and further improving its overall protection performance.
