Description

Technical Field

[0001] This utility model relates to the field of rotary switch technology, and specifically to an integrated rotary switch. Background Technology

[0002] Rotary switches, as a common basic electronic component, are widely used in various electrical control and signal switching circuits. Traditional rotary switches typically adopt an independent encapsulation structure of "casing-rotating component-terminals". The casing is formed by splicing the base and cover to form a closed cavity, which contains key components such as rotating component, moving contact, stationary contact and elastic device, as well as intermediate terminals and multiple stationary terminals that extend out of the casing to serve as interfaces for electrical connection.

[0003] In practical applications, these rotary switches often cannot be directly mounted on circuit boards (PCBs). Instead, they require auxiliary components such as additional mounting brackets, snap-fit ​​structures, or screws for indirect assembly. Furthermore, the intermediate and stationary terminals of the rotary switch serve only as external interfaces to the switch body, necessitating secondary connections via wire soldering or pluggable connectors to achieve electrical conductivity with the PCB. This soldering process is prone to poor contact due to improper solder control or cold solder joints. Pluggable connections may loosen due to vibration or temperature and humidity changes, affecting the stability of circuit signal transmission. As the electronics manufacturing industry continuously increases its demands for component integration, assembly efficiency, and equipment reliability, the existing rotary switch design can no longer meet the requirements of PCB integration. The entire installation process of existing rotary switches is cumbersome, and the electrical connections are not reliable enough. This not only increases the space occupied by the switch in the overall device but also raises assembly complexity and material costs, hindering efficient automated production. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the fact that the structural design of the rotary switch in the prior art is difficult to meet the requirements of circuit board integration and installation, the whole installation process is cumbersome, and the assembly complexity and material cost are increased.

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated rotary switch, including a switch body and a circuit board. The switch body includes a rotating shaft assembly and an elastic contact foot driven by the rotating shaft assembly and disposed at the bottom of the switch body. The circuit board is provided with a contact piece assembly that makes electrical contact with the elastic contact foot. The contact piece assembly includes a common contact piece and a plurality of first contact pieces disposed on the circuit board along the movement trajectory of the elastic contact foot. The common contact piece and the plurality of first contact pieces are concentrically distributed along a circumferential direction. A mounting structure forming a plug-in fixed connection is provided between the switch body and the circuit board. When the switch body is installed in place, the elastic contact foot makes elastic contact with the contact piece assembly and slides to contact the common contact piece and the first contact pieces as the rotating shaft assembly rotates.

[0006] As a preferred embodiment, the elastic contact has two contact arms that are elastically arranged in a V-shape. One of the contact arms is always slidably connected to the common contact piece, while the other contact arm slides and switches between multiple first contact pieces. The multiple first contact pieces are respectively connected to the common contact piece through the elastic contact to form multiple control electrical circuits.

[0007] As a preferred embodiment, the rotating shaft assembly includes a rotating shaft handle rotatably disposed in the switch housing and a rotating base integrally formed at the lower end of the rotating shaft handle. The rotating base forms the bottom of the switch body, and the elastic contact foot is disposed on the lower surface of the rotating base.

[0008] As a preferred embodiment, the rotating chassis is provided with a positioning groove for mounting the elastic contact foot and a positioning boss disposed in the positioning groove; the elastic contact foot includes two limiting pieces connected to both ends of the two contact arms, and a limiting hole formed by the two contact arms and the two limiting pieces; when the elastic contact foot is installed into the positioning groove, the positioning boss passes through the limiting hole, so that the two limiting pieces elastically abut against both ends of the positioning boss to form a positioning fit.

[0009] As a preferred embodiment, the contact assembly further includes at least one second contact disposed on the movement path of the elastic contact foot. The at least one second contact is distributed at one or both ends of the circumferential distribution range of the plurality of first contact feet, and an initial stop is formed between the first contact feet and the second contact feet. The elastic contact foot drives one of the contact arms to slide between the plurality of first contact feet and the second contact feet.

[0010] As a preferred embodiment, a reset mechanism is provided between the switch body and the rotating shaft assembly. This reset mechanism is used to drive the elastic contact foot to disengage from the second contact piece and return to the initial position after the external force on the rotating shaft handle is removed. The reset mechanism includes a reset groove disposed in the switch body and a reset spring housed in the reset groove, as well as a reset block disposed on the rotating shaft handle and cooperating with the reset spring. The reset block is integrally connected to one side of the rotating shaft boss. When the rotating shaft handle drives the elastic contact foot to rotate and contact the second contact piece, the reset spring is compressed by the reset block.

[0011] As a preferred embodiment, the side wall of the rotating shaft handle is provided with a rotating shaft boss, and a mounting hole extending radially along the rotating shaft handle and disposed on the rotating shaft boss, and a spring and a position block disposed in the installation. The inner side wall of the switch body is provided with a plurality of first position slots arranged circumferentially. The position block protrudes from the mounting hole under the action of the spring and is positioned and abuts against the first position slot.

[0012] As a preferred embodiment, the inner wall of the switch body is provided with a second position groove located between the first position groove and the reset groove. The second position groove is a smooth channel continuously disposed on the inner wall of the switch body. When the elastic contact foot is electrically contacted with the second contact piece, the position top block is slidingly contacting the second position groove, and the reset block is in an energy-storing state of compressing the reset spring.

[0013] As a preferred embodiment, the mounting structure includes multiple plug-in buckles extending downward from the bottom of the housing of the switch body, and multiple plug-in holes correspondingly provided on the circuit board for the plug-in buckles to be inserted into, the plug-in buckles passing through the plug-in holes and engaging with and fixing to the back of the circuit board.

[0014] As a preferred embodiment, the circuit board is a printed circuit board, the contact assembly is a metal pad printed or soldered onto the surface of the circuit board, the circuit board is provided with transmission leads electrically connected to the contact assembly, and a spindle hole that mates with the rotating shaft assembly, the lower end of the rotating shaft handle being rotatably connected to the spindle hole.

[0015] Compared with the prior art, the technical solution of this utility model has the following advantages: 1. In the integrated rotary switch provided by this utility model, the switch body and the circuit board are directly connected and fixed through an installation structure. By setting the elastic contact at the bottom of the switch body and forming a corresponding contact assembly on the circuit board, the contact assembly includes a common contact and multiple first contacts concentrically distributed on the circuit board along the circumference. This ensures that when the rotating shaft assembly rotates, it drives the elastic contact to conduct the control circuit between the common contact and the first contacts, achieving the purpose of multi-position and multi-circuit control. When the switch body is installed in place, the elastic contact directly forms a stable pressure contact with the contact assembly on the circuit board due to its own elasticity, realizing the simultaneous completion of electrical connection and mechanical installation. This eliminates the need for secondary welding or plugging steps, improves the reliability and long-term stability of electrical connection, simplifies the assembly process, is suitable for automated and assembly line production, reduces material costs and assembly complexity, and the rotary switch designed with this technical solution achieves three-dimensional integration of the switching function and the circuit board. It has a compact structure, saves internal space of the equipment, improves assembly efficiency, and is conducive to the miniaturization and high-density development of electronic products.

[0016] 2. In the integrated rotary switch provided by this utility model, the elastic contact foot is designed with two contact arms of a V-shaped structure. The elastic deformation of the V-shaped structure can adaptively compensate, and the elastic force of the two contact arms provides a constant and adaptive contact pressure, ensuring that the two contact arms are in close contact with the contact piece. No additional spring components are required, simplifying the structure. By designing one of the contact arms to always slide on the common contact piece, the constant and uninterrupted continuity of the common electrical circuit is ensured. The other contact arm is switched between different first contact pieces, ensuring the reliability of the contact and the clear gear function, thereby realizing absolutely reliable common terminal conduction and efficient electrical circuit switching.

[0017] 3. In the integrated rotary switch provided by this utility model, the user can clearly distinguish the function level switching by the elastic contact sliding between the first and second contact pieces through the rotation feel. When the elastic contact contacts the second contact piece, the rotary switch is switched to the momentary reset position. At this time, the reset mechanism is in an energy storage state. Once the external force applied to the rotating shaft is removed, the reset spring of the reset mechanism releases energy to drive the rotating shaft assembly to automatically disengage the elastic contact from the second contact piece and return to the initial position. This reset mechanism not only eliminates the manual reset step and reduces operating costs, but also achieves instant response by releasing the handle, thus improving equipment safety. This structural design, through clear position division, automatic reset mechanism, and integrated design, integrates two position function modes, namely position holding and automatic reset, in the same rotation operation. The user can complete all controls through a single operating component, making operation simple and convenient. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "first", "second" and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model based on the specific circumstances.

[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Example The following is a detailed description of this embodiment with reference to the accompanying drawings: This embodiment provides, as follows: Figure 1-5 An integrated rotary switch is shown, comprising a switch body 1 and a circuit board 8. The switch body 1 includes a rotating shaft assembly and an elastic contact 2 driven by the rotating shaft assembly and disposed at the bottom of the switch body 1. The circuit board 8 is provided with a contact assembly that makes electrical contact with the elastic contact 2. The contact assembly includes a common contact 91 and a plurality of first contacts 92 disposed on the circuit board 8 along the movement trajectory of the elastic contact 2. The common contact 91 and the plurality of first contacts 92 are concentrically distributed along a circumferential direction. A mounting structure is provided between the switch body 1 and the circuit board 8 to form a plug-in fixed connection. When the switch body 1 is installed in place, the elastic contact 2 makes elastic contact with the contact assembly and slides in contact with the common contact 91 and the first contacts 92 as the rotating shaft assembly rotates.

[0026] In the above embodiments, the switch body 1 and the circuit board 8 are directly connected and fixed by an installation structure. By setting the elastic contact 2 at the bottom of the switch body 1 and forming a corresponding contact assembly on the circuit board 8, it is ensured that when the rotating shaft assembly rotates, the elastic contact 2 is driven to conduct the control circuit between the common contact 91 and the first contact 92, thereby achieving the purpose of multi-position and multi-circuit control. When the switch body 1 is installed in place, the elastic contact 2 forms a stable pressure contact with the contact assembly on the circuit board 8 by virtue of its own elasticity, realizing the synchronous completion of electrical connection and mechanical installation, eliminating the steps of secondary welding or plugging, improving the reliability and long-term stability of electrical connection. This installation design simplifies the assembly process, is suitable for automated and assembly line production, reduces material costs and assembly complexity. The rotary switch designed with this technical solution realizes the three-dimensional integration of the switching function and the circuit board, with a compact structure, saving internal space of the equipment, improving assembly efficiency, and facilitating the development of electronic products towards miniaturization and high density.

[0027] The following is combined with Figure 1-4 The specific setup method for the hinge assembly is explained in detail: The rotating shaft assembly includes a rotating shaft handle 3 rotatably disposed in the switch housing and a rotating base 4 integrally formed at the lower end of the rotating shaft handle 3. The rotating base 4 constitutes the bottom of the switch body 1. The elastic contact 2 is disposed on the lower bottom surface of the rotating base 4. More preferably, the elastic contact 2 has two contact arms 21 elastically disposed in a V-shape. One contact arm 21 is always slidably connected to the common contact piece 91, and the other contact arm 21 slides and switches between multiple first contact pieces 92. The two contact arms 21 of the elastic contact 2 conduct the electrical circuit between the common contact piece 91 and any of the first contact pieces 92, thereby realizing the multi-circuit control function of the rotary switch. In this structural configuration, the two contact arms 21 utilize the elastic deformation of the V-shaped structure for adaptive compensation. This allows the elastic contact foot 2 to provide constant, adaptive contact pressure through the self-elastic force of the two contact arms 21, ensuring tight contact between the two contact arms 21 and the contact plate assembly. This eliminates the need for additional spring components, simplifying the structure. By designing one of the contact arms 21 to always slide on the common contact plate 91, the constant and uninterrupted continuity of the common electrical circuit is ensured. The other contact arm 21 is connected to different first contact plates 92 for sliding switching, ensuring contact reliability and a clear gear function. This achieves absolutely reliable common terminal conduction and efficient electrical circuit switching.

[0028] To facilitate reliable installation of the elastic contact 2, the rotating chassis 4 is provided with a positioning groove 41 for installing the elastic contact 2 and a positioning boss 42 disposed in the positioning groove 41. The elastic contact 2 includes two limiting pieces 22 connected to both ends of the two contact arms 21, and a limiting hole formed by the two contact arms 21 and the two limiting pieces 22. When the elastic contact 2 is installed into the positioning groove 41, the positioning boss 42 passes through the limiting hole, so that the two limiting pieces 22 elastically abut against both ends of the positioning boss 42 to form a positioning fit. This installation design allows the elastic contact 2 to form an elastic snap-fit ​​fit with the positioning boss 42 in the positioning groove 41, thereby quickly and reliably installing the elastic contact on the rotating chassis. The installation is stable and reliable. This installation structure of the elastic contact is simple, convenient and quick to install, and improves assembly efficiency.

[0029] In this embodiment, reference Figure 5The contact assembly further includes at least one second contact 93 disposed on the movement path of the elastic contact 2. The second contact 93 is provided with two at intervals and is distributed at one or both ends of the circumferential distribution range of the plurality of first contact 92, and forms an initial position between the first contact 92 and the second contact 93. The elastic contact drives one of the contact arms 21 to switch and slide between the plurality of first contact 92 and the second contact 93. The rotary switch has a plurality of function positions formed by the cooperation of the elastic contact 2 and the first contact 92, and at least one reset position formed by the cooperation of the elastic contact 2 and the second contact 93. The first contact 92 is the core of the function position and corresponds to different functional circuits of the circuit. A reset mechanism is provided between the switch body 1 and the rotating shaft assembly. This reset mechanism is used to drive the elastic contact 2 to disengage from the second contact piece and return to the initial position after the external force is removed from the rotating shaft handle 3. The reset mechanism includes a reset groove 11 disposed in the switch body 1 and a reset spring 6 housed in the reset groove 11, as well as a reset block 7 disposed on the rotating shaft handle 3 and cooperating with the reset spring 6. The reset block 7 is integrally connected to one side of the rotating shaft boss 31. When the rotating shaft handle 3 drives the elastic contact 2 to rotate and contact the second contact piece 93, the reset spring 6 is compressed by the reset block 7, so that the reset spring 6 is compressed and stores energy. The reset block 7 and the reset groove 11 are respectively arc-shaped. With this structural design, users can clearly distinguish the function level switching by sliding the elastic contact 2 between the first contact piece 92 and the second contact piece 93 through rotation. When the elastic contact 2 switches to contact the second contact piece 93, the reset mechanism is in an energy storage state. Once the external force applied to the rotating shaft 3 is removed, the reset spring 6 of the reset mechanism releases energy to drive the rotating shaft assembly to automatically disengage the elastic contact 2 from the second contact piece 93 and return to the initial level. This reset mechanism not only eliminates the need for manual reset steps and reduces operating costs, but also achieves instant response by simply releasing the handle, thus improving equipment safety. This structural design, through clear level division, automatic reset mechanism, and integrated design, integrates both level holding and automatic reset function modes in the same rotation operation of the rotary switch. Users can complete all controls through a single operating component, making operation simple and convenient.

[0030] To clearly define the switching boundary between the function and reset positions of the rotary switch and improve operational clarity, a positional structure is provided between the rotating shaft assembly and the switch body 1. Figure 2-5As shown, the specific configuration of the gear position structure is as follows: The side wall of the rotating shaft handle 3 is provided with a rotating shaft boss 31, and a mounting hole is provided on the rotating shaft boss 31 extending radially along the rotating shaft handle 3, and a spring and a gear position top block 53 are provided in the installation. Multiple gear position slots are arranged circumferentially on the inner side wall of the switch body 1. The gear position top block 53 protrudes from the mounting hole under the action of the spring and cooperates to position and abut against one of the gear position slots. Multiple first gear position slots 51 correspond to multiple first contact pieces 92. Multiple first gear position slots 51 are distributed at intervals to form independent functional adjustment areas. When the gear position top block 53 is inserted into a certain first gear position slot 51, the elastic contact 2 is stably attached to the corresponding first contact piece 92. Mechanical positioning and electrical conduction are realized simultaneously, preventing the elastic contact 2 from disengaging from the first contact piece 92 due to slight shaking of the rotating shaft, and ensuring the reliability of the functional gear circuit connection. In a further preferred configuration, the inner wall of the switch body 1 is provided with a second position groove 52 located between the first position groove 51 and the reset groove 11. The second position groove 52 is a smooth channel continuously provided on the inner wall of the switch body 1. The length and position of the second position groove 52 are matched with the second contact piece 93. When the elastic contact foot 2 is in electrical contact with the second contact piece 93, the position top block 53 is in positive sliding contact in the second position groove 52, and the reset spring 6 is compressed by the reset block 7 and is in an energy storage state. Through the smooth transition of the second position groove 52 and the superposition of the energy storage resistance of the reset mechanism, a smooth but damped reset position feel is formed.

[0031] As can be seen from the above gear structure design, the spring provides continuous radial elastic force to the gear top block 53, ensuring that it always abuts against the gear slot on the inner wall of the switch body 1. When the rotating shaft 3 rotates, it causes the top block to engage / disengage from different gear slots, generating clear gear feedback. The user can accurately determine whether to switch to the target gear by feel. The gear slots are divided into multiple first gear slots 51 and second gear slots 52 distributed along the circumferential direction on the inner wall of the switch body 1. The user can operate by rotating the rotating shaft 3 of the switch body 1. When the driving elastic contact slides between multiple first contact pieces 92, the corresponding driving gear top block 53 switches positions between multiple first gear slots 51. Each gear has a clear engagement / disengagement mechanism. The switch features a multi-position adjustment mechanism for precise operation, enabling position locking and preventing position shifts caused by equipment vibration or accidental touches, thus ensuring circuit stability. When the elastic contact 2 slides towards the second contact 93, the position top block 53 moves from the independent first position slot 51 into the smooth second position slot 52, changing the feel from a click-type switching to a smooth, non-clicking sliding motion, providing a clear operational warning and improving operational clarity. At this time, the reset spring 6 of the reset mechanism is compressed and stored by the reset block 7. Once the rotating shaft handle is released, the reset mechanism releases energy, driving the elastic contact to automatically disengage from the second contact and return to the initial position, thus realizing the rotary switch's position reset function and improving operational convenience.

[0032] In this embodiment, the switch body 1 is fixed to the circuit board 8 by a mounting structure. The circuit board 8 is a printed circuit board 8, and the contact assembly is a metal pad printed or soldered onto the surface of the circuit board 8. The circuit board 8 is provided with transmission guides 82 electrically connected to the contact assembly, and a shaft hole that mates with the rotating shaft assembly. The lower end of the rotating shaft shank 3 is rotatably connected to the shaft hole, and the upper end of the rotating shaft shank 3 is a half-shaft structure extending out from the top of the switch body 1. The first contact 92 and the second contact 93 are distributed circumferentially with the shaft hole as the center. More preferably, the mounting structure includes a plurality of plug-in buckles 12 extending downward from the bottom of the housing of the switch body 1, and the circuit board 8 is provided with a plurality of plug holes 8 for the plug-in buckles 12 to be inserted. 1. The plug-in buckle 12 passes through the plug hole and is fixed to the back of the circuit board 8. Multiple plug-in buckles 12 adopt an asymmetrical anti-error design, so that the switch body 1 can only be installed on the circuit board 8 in one correct direction. This plug-in buckle 12 is directly integrated into the bottom of the switch body 1, without the need for additional expansion of the switch volume. The structure is compact. The installation buckle structure is set. During the installation process, the end of the plug-in buckle 12 will deform and pass through the plug hole 81. After passing through, it will quickly spring back and lock with the back of the circuit board, which can form a continuous mechanical fixing force. This can prevent the switch from loosening due to vibration during the transportation and operation of the whole machine. No screws, solder or auxiliary brackets are needed, which simplifies the installation structure and operation process, and quickly completes the assembly. It realizes the integrated and modular installation effect of the product and greatly improves the efficiency of automated production.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
