Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connection equipment, in particular to an integrated rotary switch. BACKGROUND

[0002] The existing rotary switch usually adopts the method of connecting the circuit board with the conductive sheet or the terminal. Although it can realize the basic functional requirements, the cost is high. In the connection between the traditional rotary switch and the load and the power supply, the method of directly inserting the power line into the conductive sheet is usually adopted. This method is not only inconvenient in connection, but also prone to falling off, which affects the stability and reliability of the product.

[0003] Common solutions: circuit board and conductive sheet connection method: the conductive points on the circuit board are connected with the conductive sheet inside the rotary switch through welding or slot. The advantage of this method is stable connection, but the disadvantage is high cost and large space occupation, which is not conducive to miniaturization design.

[0004] Direct insertion method: the power line is directly inserted into the conductive sheet inside the rotary switch, that is, the wire spring, and the power line is soft. Sequential insertion is not only low in efficiency, but also cannot realize automatic assembly. In addition, the connection is not stable and is prone to loosening, especially in a vibrating environment.

[0005] Screw fixing method: the power line is fixed on the conductive sheet by screw. Although the connection is firm, the installation is complex and time-consuming, which is not suitable for large-scale production. SUMMARY

[0006] In order to solve the problems of complex assembly, high cost, poor connection stability and inability to realize automatic assembly of the existing rotary switch, the present application provides an integrated rotary switch.

[0007] The present application provides an integrated rotary switch, which adopts the following technical scheme:

[0008] An integrated rotary switch, comprising a shell, a control assembly connected with a control circuit, and a first input assembly, a second input assembly, a first output assembly and a second output assembly installed in the shell;

[0009] One end of the control assembly is located in the shell and is rotationally connected with the shell;

[0010] The first input assembly is connected with the first output assembly and is integrally formed;

[0011] One end of the second input assembly and the second output assembly is respectively connected with the control assembly, and the first input assembly, the second input assembly, the first output assembly and the second output assembly respectively have conductive properties;

[0012] The first input component and the second input component are connected with the power supply respectively, and the first output component and the second output component are connected with the load respectively.

[0013] By adopting the above technical scheme, the circuit board design is cancelled, and the connection of the power supply and the load is realized by using multiple groups of conductive sheets and wiring terminals, which effectively reduces the production cost, simplifies the overall structure, and significantly reduces the volume of the integrated rotary switch. By integrally forming the first input component and the first output component, not only the cost and the overall volume are reduced, but also the automatic integrated assembly is realized, which greatly improves the production efficiency.

[0014] Preferably, the shell is divided into an upper cover and a lower cover, the upper cover covers the lower cover, the control component is arranged through the upper cover at one end and inserted into the lower cover at the other end, and the first input component, the second input component, the first output component and the second output component are arranged on the lower cover respectively.

[0015] The upper cover has a first clamping part and a second clamping part, and the lower cover has a first through part and a second through part, the first clamping part is clamped with the first through part, and the second clamping part is clamped with the second through part.

[0016] By adopting the above technical scheme, the shell is composed of the upper cover and the lower cover, the upper cover and the lower cover are tightly connected through the clamping of the first clamping part and the first through part and the clamping of the second clamping part and the second through part, which ensures the stability and sealing of the shell and effectively prevents the internal components from loosening or external impurities from entering. At the same time, the control component is arranged through the upper cover at one end and inserted into the lower cover at the other end, which facilitates the operation end of the control component to extend out of the shell, facilitates the user operation, and ensures the functional integrity of the rotary switch. In addition, the first input component, the second input component, the first output component and the second output component are arranged on the lower cover respectively, which optimizes the utilization of the internal space, improves the assembly efficiency and stability, simplifies the assembly process, enhances the mechanical strength and protection ability of the whole device, and makes the rotary switch more suitable for application in the automatic assembly production line, improves the production speed while ensuring the product quality consistency.

[0017] Preferably, a plurality of accommodating parts are arranged on the lower cover, and the plurality of accommodating parts are used for accommodating and positioning the first input component, the second input component, the first output component and the second output component.

[0018] By adopting the above technical scheme, the plurality of accommodating parts on the lower cover can accurately accommodate and position the first input component, the second input component, the first output component and the second output component. The above structure effectively improves the assembly precision of each component, avoids the functional failure or poor contact problem caused by position deviation. At the same time, by optimizing the spatial layout of the components, the overall volume of the integrated rotary switch is further reduced, and the stability and reliability of the product are enhanced.

[0020] By adopting the above technical solution, the pressing part can effectively press and position the first input assembly, the second input assembly, the first output assembly and the second output assembly. Specifically, the above structure can ensure the stability and accuracy of each assembly inside the shell, avoid the problem of poor electrical connection caused by looseness or deviation, and thus improve the reliability and safety of the product. At the same time, the design of the pressing part simplifies the assembly process, which helps to improve production efficiency and reduce assembly difficulty.

[0021] Preferably, the first input assembly and the first output assembly are in a sheet shape, and the second input assembly and the control assembly connecting part and the second output assembly and the control assembly connecting part are also in a sheet shape.

[0022] The first input assembly and the second input assembly are in a needle shape with the power supply connecting part.

[0023] The first output assembly and the second output assembly are in a needle shape with the load connecting part.

[0024] By adopting the above technical solution, the first input assembly and the first output assembly of the rotary switch are in a sheet shape with the connecting part, which can effectively increase the contact area, reduce the resistance and improve the conductivity. At the same time, the second input assembly and the control assembly connecting part and the second output assembly and the control assembly connecting part are also in a sheet shape, which helps to enhance the mechanical stability, ensure reliable connection and reduce the risk of looseness. In addition, the first input assembly and the second input assembly are in a needle shape with the power supply connecting part, and the first output assembly and the second output assembly are also in a needle shape with the load connecting part, so that the entire rotary switch can realize pin type connection, which is convenient for automatic assembly, significantly improves the production efficiency, simplifies the operation process and avoids the problem of easy falling off of the traditional insertion of the conductive sheet.

[0025] Preferably, the control assembly includes a control shaft and a connecting part, one end of the connecting part is connected to the control shaft, and the connecting part abuts against the second input assembly.

[0026] By adopting the technical scheme, the design that the one end of the connecting component is clamped to the control shaft can ensure stable connection between the control shaft and the connecting component, and the abutting mode of the connecting component and the second input assembly realizes reliable contact and electrical conduction of the second input assembly. The complex connection mode of the traditional circuit board, the conductive sheet and the terminal is reduced, the assembly difficulty is reduced, and the assembly efficiency is improved. In addition, the structure can realize good electrical connection without additional fixing parts, and the production cost is further reduced.

[0027] Preferably, the control shaft is provided with a first elastic component and a limiting component, the first elastic component is embedded in the control shaft, the limiting component abuts against the first elastic component and the upper cover respectively, the first elastic component has elasticity, and the limiting component has an arc-shaped portion.

[0028] In summary, the application has the following beneficial effects:
