Abstract
Description
Technical Field
[0001] This utility model relates to the field of power switch technology, specifically a high-current rocker switch. Background Technology
[0002] A rocker switch, also known as a rocker switch or wave switch, has the same structure as a toggle switch, except that the toggle handle is replaced with a rocker shape. It is commonly used as a power switch in electronic equipment, household appliances, and small appliances. Based on its contact function, it is divided into several types, such as single-pole single-throw and double-pole double-throw. Some rocker switches have indicator lights. Its function is the same as all other switches: to cut off and connect current. In the main circuit, it plays an important role in the process of AC mains input and DC output, including inversion, rectification, and filtering.
[0003] However, existing rocker switches switch the current between left and right by pressing the left and right buttons. In high-humidity environments, these switches are not waterproof, which affects their lifespan. Furthermore, the existing rocker switches use a one-piece design for the mounting base and socket, which means that if the socket or components inside the mounting base are damaged during use, the entire rocker switch needs to be replaced, increasing the cost and making them less practical. Summary of the Invention
[0004] The purpose of this utility model is to provide a high-current rocker switch to solve the problems mentioned in the background art. In the process of switching, the existing rocker switches achieve the purpose of cutting off and connecting the current by pressing left and right back and forth. However, when used in high humidity environments, the waterproof performance of this type of switch is poor, which affects the service life of the switch. In addition, the existing rocker switches use the fixing base and the socket as one piece in the design process. This leads to the need to replace the entire rocker switch if the components in the socket or fixing base are damaged during the use of the rocker switch, which increases the cost of use and has poor practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-current rocker switch, including a fixed base, a protective cover snapped onto the top of the fixed base, a connecting cavity formed inside the fixed base, a socket snapped into the connecting cavity, a snap-fit interface formed on the outer wall of the connecting cavity at the front and rear ends, a guide groove formed on the bottom surface of the fixed base at a position opposite to the snap-fit interface, and the guide groove communicating with the snap-fit interface, and an elastic snap-fit block adapted to the snap-fit interface fixedly connected to the surface of the socket, and the elastic snap-fit block snapping into the snap-fit interface.
[0006] Preferably, a button is rotatably connected to the top surface of the protective cover, and a corrugated waterproof sleeve is fixedly connected between the button and the protective cover.
[0007] Preferably, fixing plates are fixedly connected to the left and right ends of the outer wall of the fixing base, and fixing strips are fixedly connected to the surface of the fixing plates.
[0008] Preferably, a first connecting layer is fixedly connected to the top of the outer wall of the fixing base, and a second connecting layer is fixed to the inner wall of the protective cover, and the second connecting layer and the first connecting layer are interlocked with each other.
[0009] Preferably, the protective cover and the corrugated waterproof sleeve are integrally molded, and both the protective cover and the corrugated waterproof sleeve are made of rubber material.
[0010] Beneficial effects
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0012] 1. Combining the structural design of this utility model, by using a snap-fit method between the fixing base and the socket to replace the traditional integrated design, the cost of use can be reduced. It can also flexibly adapt to sockets with various pin positions, making it more practical.
[0013] 2. By setting a corrugated waterproof sleeve between the protective cover and the button, the gap between the protective cover and the button is reduced. At the same time, the protective cover and the corrugated waterproof sleeve adopt an integrated design, thereby increasing their sealing performance. Attached Figure Description

[0022] like Figure 1-2 This is a schematic diagram of a high-current rocker switch according to a preferred embodiment of the present invention. In this embodiment, the high-current rocker switch includes a fixed base 1, a protective cover 2 snapped onto the top of the fixed base 1, a connecting cavity 11 inside the fixed base 1, a socket 3 snapped into the connecting cavity 11, and snap-fit interfaces 12 on the outer wall of the connecting cavity 11 at the front and rear ends. A guide groove 13 is formed on the bottom surface of the fixed base 1 at a position opposite to the snap-fit interfaces 12, and the guide groove 13 communicates with the snap-fit interfaces 12. The guide groove 13 facilitates the guiding effect of the socket 3 on the snap-fit block 31 when it is inserted into the connecting cavity 11. A flexible snap-fit block 31 adapted to the card interface 12 is fixedly connected, and the snap-fit block 31 is snapped into the card interface 12, thereby realizing the connection and fixation between the docking socket 3 and the fixed base 1; at the same time, if disassembly is required, simply use a tool to push the snap-fit block 31 from the card interface 12 to separate the snap-fit block 31 from the card interface 12, and the disassembly work can be completed; combined with the structural design of this utility model, by adopting the interlocking method between the fixed base 1 and the docking socket 3, the traditional integrated design can be replaced, which can reduce the cost of use, and can also flexibly adapt to docking sockets 3 with various pin positions, thus improving practicality.
[0023] In this embodiment, a button 4 is rotatably connected to the top surface of the protective cover 2, and a corrugated waterproof sleeve 5 is fixedly connected between the button 4 and the protective cover 2; by setting the corrugated waterproof sleeve 5 between the protective cover 2 and the button 4, the gap between the protective cover 2 and the button 4 is reduced.
[0024] In this embodiment, the left and right ends of the outer wall of the fixed base 1 are fixedly connected to the fixed plate 14, and the surface of the fixed plate 14 is fixedly connected to the fixed strip 15. This structural design increases the firmness of the fixed base 1 during installation.
[0025] In this embodiment, a first connecting layer 16 is fixedly connected to the top of the outer wall of the fixed base 1, and a second connecting layer 21 is fixed to the inner wall of the protective cover 2. The second connecting layer 21 and the first connecting layer 16 are interlocked with each other. This structural design effectively protects the safety of the internal components of the rocker switch and provides better protection.
[0026] In this embodiment, the protective cover 2 and the corrugated waterproof sleeve 5 are integrally molded, and both the protective cover 2 and the corrugated waterproof sleeve 5 are made of rubber material. At this time, the protective cover 2 and the corrugated waterproof sleeve 5 adopt an integrated design, thereby increasing the connection and sealing between them.
