Description

Technical Field

[0001] This utility model relates to the field of rocker switch technology, and in particular to a double-contact contact structure inside a rocker switch. Background Art

[0002] The contacts of rocker switches used in electronic appliances and mechanical equipment are generally single-point contacts with small conducting current. When the switch is used in a circuit with a control current of 16A or more, the contacts are prone to overheating, which may cause the switch components or fuses to burn out or even the equipment to be damaged. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a double-contact contact structure inside a rocker switch. The structure is simple and easy to process, and it can achieve double-contact conductive contact, thereby increasing the conduction current and meeting the needs of high-power equipment. At the same time, it can reduce heat generation and extend the service life of the electronic components inside the switch.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The rocker switch features a double-contact structure. It includes a pressing element, a moving contact, and a stationary contact. The pressing element is hinged to the upper end of the switch body. The moving contact is hinged within the switch body and is connected to the pressing element. The stationary contact is located below the moving contact and is fixedly connected to a conductive terminal. The conductive terminal is embedded in the switch body and electrically connected to a power supply / circuit control component. Pushing the pressing element causes it to flip on the switch body, pushing the moving contact against or away from the stationary contact to achieve circuit connection or disconnection.

[0006] Both the stationary and moving contacts have convex arc surfaces on their contact ends. A groove is provided in the center of each arc surface. When the moving contact contacts the stationary contact, the ends of the two side walls of the groove contact the other arc surface, thus forming a double-contact contact structure.

[0007] As a further explanation of the above technical solution:

[0008] In the above technical solution, the moving contact is detachably fixed at the end of an arc-shaped mounting plate. The mounting plate is hinged inside the main body of the switch and is located at the lower end of the pressing member and in contact with it.

[0009] In the above technical solution, the stationary contact is detachably fixed at one end of the conductive terminal.

[0010] Compared with the prior art, the advantages of this utility model are: simple structure, convenient processing, and the ability to achieve double contact point conduction contact, thereby increasing the conduction current and meeting the needs of high-power equipment. At the same time, the groove setting can increase the heat dissipation area of ​​the contact, improve heat dissipation efficiency, reduce heat generation, and extend the service life of each electronic component in the switch.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0017] like Figure 1-3As shown, the rocker switch has a double-contact structure. The rocker switch has a pressing element 1, a moving contact 2, and a stationary contact 3. The pressing element 1 is hinged to the upper end of the switch body. The moving contact 2 is hinged inside the switch body and is connected to the pressing element 1. The stationary contact 3 is located below the moving contact 2 and is fixedly connected to a conductive terminal 4. The conductive terminal 4 is embedded in the switch body and electrically connected to a power supply / circuit control component. Pushing the pressing element 1 causes it to flip on the switch body, thus pushing the moving contact 2 to press against or move away from the stationary contact 3 to achieve circuit connection or disconnection.

[0018] The contact surfaces of the stationary contact 3 and the moving contact 2 are both raised arc surfaces 5. A cutting groove 6 is provided in the center of either arc surface 5. When the moving contact 2 contacts the stationary contact 3, the ends of the two side walls of the cutting groove 6 contact the other arc surface 5, thereby forming a double contact structure.

[0019] In this embodiment, the moving contact 2 is detachably fixed at the end of an arc-shaped mounting plate 7, the mounting plate 7 is hinged inside the main body of the switch and is located at the lower end of the pressing member 1 and in contact with it; the stationary contact 3 is detachably fixed at one end of the conductive terminal 4.

[0020] In use, the push-pressing part 1 is rotated relative to the main body of the switch, and one end of it pushes the mounting plate 7 to rotate synchronously, causing the moving contact 2 to press against the stationary contact 3. Since the two facing end faces are both arc surfaces 5, and one arc surface 5 is provided with a groove 6, the top of one arc surface 5 extends into the groove 6 and one end on both sides presses against the other arc surface 5, thereby realizing a double-point contact connection.

[0021] This utility model has a simple structure and is easy to process. It can achieve double contact point conduction contact, thereby increasing the conduction current and meeting the needs of high-power equipment. At the same time, the groove 6 can increase the heat dissipation area of ​​the contact, improve heat dissipation efficiency, reduce heat generation, and extend the service life of the electronic components in the switch.

[0022] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
