Description

Technical Field

[0001] This utility model relates to the field of waterproof switch technology, specifically to a waterproof rocker switch with a protective box. Background Technology

[0002] A waterproof rocker switch (also known as a rocker switch or I / O switch) is an electrical switch based on mechanical principles. Its appearance resembles a ship's hull, and the circuit is switched on or off by the up-and-down swing of the rocker.

[0003] Existing waterproof rocker switches typically enhance their protection level by installing waterproof covers on the outside or inside of the rocker switch's moving parts. However, after the rocker switch is switched on and off for a long time, the waterproof cover is prone to deformation and displacement, causing the waterproof cover to lose its sealing fit with the switch housing. External impurities or moisture can easily enter the rocker switch, causing it to malfunction. Furthermore, since existing rocker switches are all installed on the surface of the equipment, the operating parts of the rocker switch are more likely to come into contact with the external environment, accelerating the aging and damage of the waterproof cover.

[0004] In view of this, there is an urgent need to design a waterproof rocker switch with a protective box to solve the defects of existing waterproof rocker switches. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a waterproof rocker switch with a protective box, comprising a base, a cover connected to the base, and a rocker button movably connected to the cover. A protective shield is attached to the cover and connected to the rocker button. The protective box includes a mounting cavity with a positioning edge at its bottom. A positioning step is provided on the cover near the rocker button. The protective shield includes a rubber ring portion and a rubber sleeve portion. The inner cavity of the rubber ring portion has a positioning cavity, with an upper rubber ring layer and a lower rubber ring layer on its upper and lower sides. The positioning step is connected within the positioning cavity. The upper and lower rubber ring layers are respectively attached to the upper and lower end faces of the positioning step, and the lower rubber ring layer is attached to the positioning edge. First clamping members are provided on both sides of the cover, engaging with the inner wall and bottom of the positioning edge. The rocker button is located within the mounting cavity. Detachable second clamping members are provided on both sides of the protective box.

[0006] In one possible implementation, the first clamping member includes a first guide portion and a first clamping portion, wherein the first clamping portion has a clamping step sequentially provided on the side near the positioning edge, the clamping step abutting against the positioning edge, and the lower rubber ring layer is clamped between the positioning step and the positioning edge.

[0007] In one possible implementation, the rocker button includes a button body, a movable seat, and a button retainer plate. The button body is hinged to the housing, the movable seat is connected inside the button body, the button retainer plate is connected to the end of the button body, and the rubber sleeve is fitted over the outside of the button body.

[0008] In one possible implementation, the inner wall of the button body is provided with a snap-fit ​​protrusion, and the outer periphery of the movable seat is provided with a snap-fit ​​edge. The movable seat is connected to the button body through the engagement of the snap-fit ​​edge and the snap-fit ​​protrusion.

[0009] In one possible implementation, the lower end of the movable seat is provided with a toggle post, and a compression spring and a toggle block are connected inside the toggle post.

[0010] In one possible implementation, the upper end of the movable seat is provided with an indicator cavity, and an indicator circuit is connected inside the indicator cavity. The indicator circuit includes an indicator light and a current-limiting resistor connected in series.

[0011] In one possible implementation, the end of the button body is provided with a snap-fit ​​groove and a plug-in groove, and the button buckle plate is provided with a hook plate and a plug plate respectively opposite to the snap-fit ​​groove and the plug-in groove. The hook plate is connected in the snap-fit ​​groove, and the plug plate is connected in the plug-in groove.

[0012] In one possible implementation, the downward extension of the positioning edge forms a protective portion located around the perimeter of the housing.

[0013] In one possible implementation, clamping slots are provided on both sides of the protective cover. The second clamping member includes a second insertion part, a second guide part, and a second clamping part in sequence. The second guide part is connected to the side of the second insertion part, and the second insertion part is connected in the clamping slot.

[0014] In one possible implementation, the base is connected to two stationary contact feet, and a movable contact piece is connected to the stationary contact feet.

[0015] The assembly and use of the waterproof rocker switch with protective box in this technical solution is as follows: The protective cover is fitted onto the housing and rocker button, so that the positioning step is connected to the positioning cavity of the rubber ring. The rocker switch is then inserted into the mounting cavity of the protective box, so that the first clamping member and the bottom of the positioning edge form a clamping fit. The lower rubber ring is pressed between the positioning step and the positioning edge, thereby preventing the protective cover from shifting or falling off during use. The waterproof rocker switch with protective box is then connected to the mounting port of the corresponding device via the second clamping member.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages: The core of this waterproof rocker switch with a protective box lies in the design of the rubber ring part of the protective cover and the synergistic contact between the protective box and the positioning step. The positioning step is precisely clamped between the upper and lower rubber ring layers, while the lower rubber ring layer is pressed between the positioning step and the positioning edge of the protective box. This structure firmly clamps the rubber ring part of the protective cover between the positioning step of the cover and the positioning edge of the protective box. The first clamping member further clamps the inner wall and bottom of the positioning edge, achieving double-layer sealing protection. This fundamentally prevents the protective cover from deforming, displacing or falling off due to long-term operation of the button, ensuring the durability of the rocker switch's sealing fit, and effectively preventing external contaminants such as water, dust, and oil from entering the inside of the switch or the gap between the cover and the protective cover, preventing the failure of the switching function due to internal contact corrosion or short circuit.

[0017] The waterproof rocker switch with protective box in this technical solution is pre-assembled as a component (base, cover, button and protective cover), and then the whole is installed into the protective box. The detachable second clamps on both sides of the protective box are used to fix the entire device to the equipment panel. The modular design simplifies the on-site installation process. The detachable second clamps can be easily removed from the equipment panel for inspection, maintenance or replacement without touching the internal wiring of the equipment.

[0018] This technical solution's protective box houses the entire rocker button within its mounting cavity, significantly reducing the rocker button's direct contact with harsh environments. This directly slows down the aging, embrittlement, and mechanical damage of the protective cover and the button itself. Attached Figure Description
