Description

Technical Field

[0001] This utility model relates to micro switches, and more particularly to a switch structure. Background Technology

[0002] In the fields of electronic control and electrical drives, microswitches, as a fundamental and widely used mechanical signal switching device, function primarily to switch the on / off state of a circuit through mechanical action. Traditional three-terminal microswitches (typically consisting of a common terminal COM, a normally open terminal NO, and a normally closed terminal NC) are widely used in industrial control, consumer electronics, automotive electrical systems, and home appliances due to their simple structure, low cost, and sensitive response, for functions such as position detection, status feedback, and function switching.

[0003] However, traditional three-terminal microswitches have an inherent technical flaw during signal switching: when the switch contacts switch from normally closed (NC) to normally open (NO) or in reverse, there is a non-overlapping disconnection period between the common terminal (COM) and the two terminals, causing a brief interruption in signal transmission. Since signal interruptions during normal switching and circuit breaks caused by faults are highly similar in appearance (both manifest as circuit disconnection), field maintenance personnel cannot easily distinguish between the two through simple signal monitoring, requiring additional testing steps and increasing the difficulty and cost of equipment maintenance. Utility Model Content

[0004] This invention provides a switch structure to solve the problem of signal interruption during signal switching in traditional three-terminal microswitches.

[0005] This application provides a switch structure, comprising: a base and a conductive connector, wherein the conductive connector is located on one side of the base and is slidable along the thickness direction of the base; the conductive connector includes a body, a first conductive contact, a second conductive contact and a third conductive contact, wherein the first conductive contact, the second conductive contact and the third conductive contact are sequentially disposed on the body along the thickness direction of the base;

[0006] It also includes: a first terminal, a second terminal and a third terminal, wherein the first terminal, the second terminal and the third terminal respectively penetrate the base, and a first conductive arm, a second conductive arm and a third conductive arm are respectively formed on one side of the base;

[0007] The conductive connector is configured such that when the conductive connector slides along the thickness direction of the base, the first conductive contact always abuts against the first conductive arm, the second conductive contact abuts against the second conductive arm, and / or the third conductive contact abuts against the third conductive arm.

[0008] According to the above-mentioned technical means, during the sliding process of the conductive connector of this utility model, at least two terminals are simultaneously connected, ensuring that there is no open circuit gap throughout the signal transmission process. Even if the contact force of one terminal gradually weakens during the contact switching process, the contact force of the other terminal has been established in advance. The signal is always transmitted through at least two parallel paths, which fundamentally avoids the "false fault" signal caused by normal switching. This is especially important for critical systems that require continuous signal feedback (such as industrial control and safety equipment), which can prevent misoperation or system failure caused by signal interruption and improve the smoothness of interaction and user experience.

[0009] When the conductive connector slides, three independent signal modes can be generated by the combination of the contact states of the second conductive contact with the second conductive arm and the third conductive contact with the third conductive arm: only the second terminal is on (the first terminal is always on, the second terminal is on, and the third terminal is off); only the third terminal is on (the first terminal is always on, the third terminal is on, and the second terminal is off); and both the second and third terminals are on simultaneously (the first terminal is always on, and both the second and third terminals are on). These three signal modes can correspond to three different control states or functions (such as gear adjustment, mode switching, etc.), significantly improving the functional expandability of the switch and making it suitable for complex scenarios requiring multi-state control.

[0010] Furthermore, the first conductive contact, the second conductive contact, and the third conductive contact are arranged in a stepped distribution.

[0011] Based on the aforementioned technical means, the stepped contact structure ensures that the three conductive contacts sequentially contact or disengage from their respective conductive arms during the sliding of the conductive connector. For example, when the conductive connector moves downward, the lower-positioned contacts, such as the first conductive contact, maintain contact preferentially, while the higher-positioned contacts, such as the second and third conductive contacts, gradually switch their contact states in a stepped sequence. This ensures that at any given time, at least two contacts are simultaneously in contact with the conductive arm, fundamentally avoiding the signal interruption problem caused by the "break-before-connect" contact behavior in traditional switches.

[0012] Furthermore, the first conductive arm, the second conductive arm, and the third conductive arm all extend along the thickness direction of the base and are spaced apart.

[0013] Based on the aforementioned technical means, the design of the three conductive arms extending along the thickness direction of the base ensures that they are completely aligned with the sliding direction (thickness direction) of the conductive connector. When the conductive connector slides, the contact movement between the contact and the arm is a linear push-pull motion, avoiding lateral force components caused by inconsistent movement directions.

[0014] Furthermore, the length of the second conductive arm is less than the length of the third conductive arm.

[0015] Based on the above technical means, the design of the second conductive arm being shorter than the third conductive arm ensures that during the sliding process of the conductive connector, the contact state between the contact and the arm presents a timing relationship of "the third contact making contact early - the second contact making contact late," ensuring that there is no open circuit gap throughout the signal transmission process, fundamentally avoiding the signal interruption problem caused by the "break-then-connect" contact of traditional switches.

[0016] Furthermore, the first conductive contact includes a first sub-conductive contact and a second sub-conductive contact, which are symmetrically arranged. The first conductive arm is held between the first sub-conductive contact and the second sub-conductive contact, and the first sub-conductive contact and the second sub-conductive contact slide in contact with the first conductive arm.

[0017] Based on the above technical means, the first conductive contact adopts a structure in which two sub-contacts symmetrically clamp the first conductive arm, forming a redundant structure with parallel conduction of two contacts, so that conduction can still be achieved when a single contact fails: if the first sub-conductive contact becomes poorly contacted due to wear, oxidation or vibration, the second sub-conductive contact can still maintain contact with the first conductive arm, ensuring continuous output of signal A, fundamentally eliminating the risk of signal loss caused by poor contact at a single point, and significantly improving the reliability of signal transmission.

[0018] Furthermore, the second conductive contact includes a third sub-conductive contact and a fourth sub-conductive contact, which are symmetrically arranged.

[0019] Based on the aforementioned technical means, the second conductive contact adopts a symmetrical dual-contact structure, forming a redundant structure with parallel conduction of two contacts during the sliding process of the conductive connector. Even if a single contact fails, conduction remains possible. If the third conductive contact experiences poor contact due to wear, oxidation, or vibration, the fourth conductive contact can still maintain contact with the second conductive arm, ensuring continuous output of signal B during switching. Simultaneously, during the dynamic process of the second conductive contact gradually disengaging from the second conductive arm, the dual-contact structure, through parallel conduction, eliminates the risk of temporary interruption of signal B caused by weakened contact force in traditional single-contact designs, ensuring the continuity of signal transmission.

[0020] Furthermore, the third conductive contact includes a fifth sub-conductive contact and a sixth sub-conductive contact, which are symmetrically arranged.

[0021] Based on the aforementioned technical means, the third conductive contact adopts a symmetrical structure with two sub-contacts, forming a redundant structure of parallel conduction of two contacts during the sliding process of the conductive connector. It can still conduct even when a single contact fails. If the fifth sub-conductive contact suffers from poor contact due to wear, oxidation, or vibration, the sixth sub-conductive contact can still maintain contact with the third conductive arm, ensuring continuous output of signal C during the switching process.

[0022] Furthermore, it also includes a sliding assembly, on which the conductive connector is mounted, and the sliding assembly is capable of sliding along the thickness direction of the base.

[0023] According to the above technical means, the sliding component, as the moving carrier of the conductive connector, forces the conductive connector to slide linearly along the thickness direction of the base through the integrated guide structure.

[0024] Furthermore, the sliding assembly includes a spring and a button, one end of the spring is mounted on the base and the other end is connected to the button; the button is movable along the thickness direction of the base; the conductive connector is mounted on the button.

[0025] According to the above-mentioned technical means, the spring, as an elastic reset element, is fixed at one end to the base and connected to the button at the other end. After being released, it can accurately return to its original position. When the user pushes the button to make the conductive connector slide, when the button is released, the elastic force of the spring will drive the button to automatically return to its initial position along the thickness direction of the base.

[0026] Furthermore, it also includes a housing and a sealing cap, the housing being fastened to the base, and the conductive connector, the first conductive arm, the second conductive arm, the third conductive arm, the spring, and at least a portion of the button being located inside the housing, with one end of the button extending outside the housing; the sealing cap is installed outside the housing and seals and covers the end of the button extending outside the housing.

[0027] According to the above technical means, the shell and the base are fastened together to form a closed cavity. Combined with the sealing cap to seal and cover the exposed end of the button, the closed cavity prevents foreign objects such as dust and metal shavings from entering the interior, and prevents poor contact between the conductive arm and the contact due to the accumulation of foreign objects.

[0028] Beneficial effects:

[0029] During the sliding process of the conductive connector of this utility model, at least two terminals are simultaneously conductive, ensuring that there is no open circuit gap throughout the signal transmission process. Even if the contact force of one terminal gradually weakens during the contact switching process, the contact force of the other terminal has been established in advance. The signal is always transmitted through at least two parallel paths, which fundamentally avoids false fault signals caused by normal switching. This is especially important for critical systems that require continuous signal feedback (such as industrial control and safety equipment), as it can prevent misoperation or system failure caused by signal interruption and improve the smoothness of interaction and user experience.

[0030] When the conductive connector slides, three independent signal modes can be generated by the combination of the contact states of the second conductive contact with the second conductive arm and the third conductive contact with the third conductive arm: only the second terminal is on (the first terminal is always on, the second terminal is on, and the third terminal is off); only the third terminal is on (the first terminal is always on, the third terminal is on, and the second terminal is off); and both the second and third terminals are on simultaneously (the first terminal is always on, and both the second and third terminals are on). These three signal modes can correspond to three different control states or functions (such as gear adjustment, mode switching, etc.), significantly improving the functional expandability of the switch and making it suitable for complex scenarios requiring multi-state control.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0052] like Figure 1 As shown, this embodiment provides a switch structure, including: a base 1 and a conductive connector 2. The conductive connector 2 is located on one side of the base 1 and can slide along the thickness direction of the base 1. The conductive connector 2 includes a body 21, a first conductive contact 22, a second conductive contact 23 and a third conductive contact 24. The first conductive contact 22, the second conductive contact 23 and the third conductive contact 24 are sequentially arranged on the body 21 along the thickness direction of the base 1.

[0053] It also includes: a first terminal 3, a second terminal 4 and a third terminal 5, the first terminal 3, the second terminal 4 and the third terminal 5 respectively penetrate the base 1, and a first conductive arm 31, a second conductive arm 41 and a third conductive arm 51 are respectively formed on one side of the base 1;

[0054] The conductive connector 2 is configured such that when the conductive connector 2 slides along the thickness direction of the base 1, the first conductive contact 22 always abuts against the first conductive support arm 31, the second conductive contact 23 abuts against the second conductive support arm 41 and / or the third conductive contact 24 abuts against the third conductive support arm 51.

[0055] The specific usage process of the switch structure is as follows:

[0056] 1. Initial state

[0057] like Figure 2 and Figure 3 As shown, the conductive connector 2 is in the original position of the base 1. At this time:

[0058] The first conductive contact 22 is always in contact with the first conductive arm 31, and the first terminal 3 is connected to the common circuit (signal A is continuously output);

[0059] The second conductive contact 23 abuts against the second conductive arm 41, and the second terminal 4 is connected to the common circuit (signal B output);

[0060] The third conductive contact 24 is not in contact with the third conductive arm 51, and the third terminal 5 is in the open state (signal C has no output).

[0061] Signal status: The system receives a combination signal of "signal A + signal B", which corresponds to the initial function (such as the device "standby mode").

[0062] 2. Signal switching

[0063] The user pushes the conductive connector 2 along the thickness direction of the base 1 (downward) by external force (such as finger pressing or mechanical linkage), and the contact state of the contact point changes dynamically during the sliding process.

[0064] like Figure 4 As shown, in stage one: the second conductive contact 23 has not completely disengaged, while the third conductive contact 24 has made contact.

[0065] First conductive contact 22: still abutting against first conductive arm 31, signal A continues to be output;

[0066] Second conductive contact 23: at least partially still in contact with second conductive arm 41, signal B continues to be output;

[0067] Third conductive contact 24: Fully contacts the third conductive arm 51, signal C is turned on.

[0068] Signal status: The system receives a combined signal of "signal A + signal B + signal C" (first state).

[0069] like Figure 5 As shown, in stage two: the second conductive contact 23 is completely disengaged, and the third conductive contact 24 is in stable contact.

[0070] First conductive contact 22: still abutting against first conductive arm 31, signal A continues to be output;

[0071] Second conductive contact 23: Completely disengaged from second conductive arm 41, signal B is interrupted;

[0072] The third conductive contact 24 remains fully in contact with the third conductive arm 51, and signal C is output stably.

[0073] Signal status: The system receives a combination signal of "signal A + signal C", which corresponds to the intermediate function (second state).

[0074] 3. Reverse reset

[0075] If the conductive connector 2 is pushed upwards to reset, the process is the opposite of the downward movement:

[0076] First conductive contact 22: Always abuts against first conductive arm 31, signal A is continuously output;

[0077] Second conductive contact 23: Makes early contact with second conductive arm 41, signal B is turned on;

[0078] Third conductive contact 24: Gradually disengages from third conductive arm 51, signal C is interrupted.

[0079] Signal status: The system seamlessly switches from "signal A + signal C" to "signal A + signal B", and the corresponding function switches back from "second state" to "standby mode".

[0080] During the sliding process of the conductive connector 2 in this embodiment, at least two terminals are simultaneously connected, ensuring that there is no open circuit gap throughout the signal transmission process. Even if the contact force of one terminal gradually weakens during the contact switching process, the contact force of the other terminal has been established in advance. The signal is always transmitted through at least two parallel paths, which fundamentally avoids the "false fault" signal caused by normal switching. This is especially important for critical systems that require continuous signal feedback (such as industrial control and safety equipment), as it can prevent misoperation or system failure caused by signal interruption and improve the smoothness of interaction and user experience.

[0081] When the conductive connector 2 slides, three independent signal modes can be generated through the combination of the contact states of the second conductive contact 23 and the second conductive arm 41, and the third conductive contact 24 and the third conductive arm 51: only the second terminal 4 is on (the first terminal 3 is always on, the second terminal 4 is on, and the third terminal 5 is off); only the third terminal 5 is on (the first terminal 3 is always on, the third terminal 5 is on, and the second terminal 4 is off); and both the second terminal 4 and the third terminal 5 are on (the first terminal 3 is always on, and both the second terminal 4 and the third terminal 5 are on). These three signal modes can correspond to three different control states or functions (such as gear adjustment, mode switching, etc.), significantly improving the functional expandability of the switch and making it suitable for complex scenarios requiring multi-state control.

[0082] In this preferred embodiment, such as Figure 2 As shown, the first terminal 3, the second terminal 4, and the third terminal 5 are embedded in the base 1, and the first conductive arm 31, the second conductive arm 41, and the third conductive arm 51 all form a clear stepped structure with the base 1, which makes the three signal modes clearly distinguishable. Users can intuitively perceive the current state through the operation feel (such as the contact feedback when sliding to the position) or the system response (such as the activation of different functions), avoiding the operation uncertainty caused by the ambiguity of signals in traditional switches.

[0083] like Figure 6 As shown, the first conductive contact 22, the second conductive contact 23, and the third conductive contact 24 are arranged in a stepped manner.

[0084] The stepped contact structure ensures that the three conductive contacts sequentially contact or disengage from their respective conductive arms during the sliding of the conductive connector 2. For example, when the conductive connector 2 moves downward, the lower-positioned contacts, such as the first conductive contact 22, maintain contact first, while the higher-positioned contacts, such as the second conductive contact 23 and the third conductive contact 24, gradually switch their contact states in a stepped sequence. This ensures that at any given time, at least two contacts are simultaneously in contact with the conductive arm, fundamentally avoiding the signal interruption problem caused by the "break-before-connect" contact behavior in traditional switches.

[0085] like Figures 2-5 As shown, the first conductive arm 31, the second conductive arm 41 and the third conductive arm 51 all extend along the thickness direction of the base 1 and are distributed at intervals.

[0086] The design of three conductive arms extending along the thickness direction of the base 1 ensures that it is completely aligned with the sliding direction (thickness direction) of the conductive connector 2. When the conductive connector 2 slides, the contact movement between the contact and the arms is a linear push-pull motion, avoiding lateral force components caused by inconsistent movement directions.

[0087] like Figures 2-5 As shown, the length of the second conductive arm 41 is less than the length of the third conductive arm 51.

[0088] The design that the length of the second conductive arm 41 is less than that of the third conductive arm 51 causes the contact state between the contact and the arm to exhibit a timing relationship of "the third contact making contact earlier - the second contact making contact later" during the sliding process of the conductive connector 2.

[0089] The third conductive contact 24 contacts the third conductive arm 51: Since the third conductive arm 51 is relatively long, when the conductive connector 2 slides to the middle position, the third conductive contact 24 has already established a stable contact with the third conductive arm 51 (signal C is turned on).

[0090] The second conductive contact 23 disengages from the second conductive arm 41: The second conductive arm 41 is relatively short, and the second conductive contact 23 only completely disengages from the second conductive arm 41 when the conductive connector 2 continues to slide (signal B is interrupted). This ensures that there is no open circuit gap throughout the signal transmission process, fundamentally avoiding the signal interruption problem caused by the "break-before-connect" contact in traditional switches.

[0091] Meanwhile, the design of the second conductive arm 41 being shorter than the third conductive arm 51 creates a structural height fit with the stepped distribution of the conductive contacts. The first conductive contact 22 is at the lowest position, followed by the second conductive contact 23, and the third conductive contact 24 is at the highest. The shorter second conductive arm 41 avoids interference with the sliding path of the third conductive contact 24, while the longer third conductive arm 51 ensures that the third conductive contact 24 can fully contact the arm throughout the sliding process. The differentiated design of the arm lengths staggers the projection positions of each arm in the thickness direction of the base, avoiding the space congestion problem caused by the dense arrangement of traditional equal-length arms, and improving the space utilization rate inside the base.

[0092] like Figure 6 As shown, the first conductive contact 22 includes a first sub-conductive contact 221 and a second sub-conductive contact 222. The first sub-conductive contact 221 and the second sub-conductive contact 222 are symmetrically arranged. The first conductive support arm 31 is sandwiched between the first sub-conductive contact 221 and the second sub-conductive contact 222, and the first sub-conductive contact 221 and the second sub-conductive contact 222 are in sliding contact with the first conductive support arm 31.

[0093] The first conductive contact 22 adopts a structure in which two sub-contacts symmetrically clamp the first conductive arm 31, forming a redundant structure with parallel conduction of two contacts. This allows the circuit to continue even when a single contact fails. If the first sub-conductive contact 221 experiences poor contact due to wear, oxidation, or vibration, the second sub-conductive contact 222 can still maintain contact with the first conductive arm 31, ensuring continuous output of signal A. This fundamentally eliminates the risk of signal loss caused by poor contact at a single point and significantly improves the reliability of signal transmission.

[0094] In this embodiment, the first sub-conductive contact 221 and the second sub-conductive contact 222 can be designed with the same structure, which reduces the types of parts and lowers the mold development and procurement costs.

[0095] like Figure 6 As shown, the second conductive contact 23 includes a third sub-conductive contact 231 and a fourth sub-conductive contact 232, which are symmetrically arranged.

[0096] The second conductive contact 23 adopts a symmetrical twin-contact structure, forming a redundant structure with parallel conduction of two contacts during the sliding process of the conductive connector 2. It can still conduct even if a single contact fails. If the third sub-conductive contact 231 experiences poor contact due to wear, oxidation, or vibration, the fourth sub-conductive contact 232 can still maintain contact with the second conductive arm 41, ensuring continuous output of signal B during switching. Simultaneously, during the dynamic process of the second conductive contact 23 gradually disengaging from the second conductive arm 41, the twin-contact structure eliminates the risk of temporary interruption of signal B due to weakened contact force in traditional single-contact designs through parallel conduction, ensuring the continuity of signal transmission.

[0097] like Figure 6 As shown, the third conductive contact 24 includes a fifth sub-conductive contact 241 and a sixth sub-conductive contact 242, which are symmetrically arranged.

[0098] The third conductive contact 24 adopts a symmetrical structure with two sub-contacts, forming a redundant structure of parallel conduction of two contacts during the sliding process of the conductive connector 2. It can still conduct when a single contact fails. If the fifth sub-conductive contact 241 has poor contact due to wear, oxidation or vibration, the sixth sub-conductive contact 242 can still maintain contact with the third conductive arm 51, ensuring that the signal C is continuously output during the switching process.

[0099] like Figure 1 As shown, it also includes a sliding component 6, and a conductive connector 2 is mounted on the sliding component 6. The sliding component 6 can slide along the thickness direction of the base 1.

[0100] The sliding component 6 serves as the moving carrier of the conductive connector 2, and through the integrated guide structure, it forces the conductive connector 2 to slide linearly along the thickness direction of the base 1.

[0101] like Figure 1 As shown, the sliding assembly 6 includes a spring 61 and a push button 62. One end of the spring 61 is mounted on the base 1, and the other end is connected to the push button 62. The push button 62 can move along the thickness direction of the base 1. The conductive connector 2 is mounted on the push button 62.

[0102] Spring 61 serves as an elastic reset element, with one end fixed to base 1 and the other end connected to button 62. It can accurately return to its original position after release. When the user pushes button 62 to slide conductive connector 2, and then releases the button, the elastic force of spring 61 will drive button 62 to automatically return to its initial position along the thickness direction of base 1.

[0103] In this preferred embodiment, the elastic coefficient of spring 61 can be adjusted according to needs (such as selecting spring 61 with moderate stiffness), so that when the user pushes the button 62, he can feel a clear change in resistance (such as from light resistance in the initial stage to moderate force in the later stage), providing segmented operation feedback and improving the feel of operation.

[0104] like Figure 1 As shown, it also includes a housing 7 and a sealing cap 8. The housing 7 is fastened to the base 1, and the conductive connector 2, the first conductive support arm 31, the second conductive support arm 41, the third conductive support arm 51, the spring 61, and at least part of the push button 62 are all located inside the housing 7, with one end of the push button 62 extending outside the housing 7; the sealing cap 8 is installed outside the housing 7 and seals and covers the end of the push button 62 extending outside the housing 7.

[0105] The housing 7 and the base 1 are fastened together to form a closed cavity. Combined with the sealing cap 8, the exposed end of the button is sealed and covered. The closed cavity prevents foreign objects such as dust and metal shavings from entering the interior, and prevents poor contact between the conductive arm and the contact due to the accumulation of foreign objects.

[0106] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
