Description

Technical Field

[0001] This application relates to the field of switch technology. Specifically, it relates to an auxiliary mechanism and a switch. Background Art

[0002] A switch is an important electrical appliance that can play the role of energizing and de-energizing in a circuit and is widely used in various occasions such as homes, industries, commerce, and public facilities. The basic function of a switch is to achieve the connection and disconnection of a circuit through manual or automatic control, thereby managing the transmission and use of electrical energy. In a switch, the contact mechanism, as an actuator, undertakes the key tasks of connecting and disconnecting the circuit and is one of the most important components of the switch. The contact mechanism usually consists of a static contact fixedly installed and a moving contact that moves relative to the static contact.

[0003] Most switches in the prior art use an external auxiliary mechanism to judge the closing status of the moving contact and the static contact. However, this external auxiliary mechanism often occupies a large space, increases the number of parts, and thus raises the cost. To overcome these problems, some new switches have started to use an internal auxiliary mechanism to monitor the closing status of the moving contact and the static contact. Although the internal auxiliary mechanism solves the problems of the external mechanism occupying space and having a high cost to a certain extent, due to the relatively close position of the internal auxiliary mechanism to the contact mechanism, the moving contact may touch the auxiliary contact during movement, which not only hinders the movement of the moving contact but also has a certain impact on its normal operation. Utility Model Content

[0007] Optionally, the moving contact also has a transition position where it is not in contact with either the closing contact or the tripping contact.

Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application to be protected, but merely represents selected embodiments of the present application. It should be noted that, without conflict, the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the protection scope of the present application.

[0028] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of this application is normally placed. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0030] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0031] In the description of the present application, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "install", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0032] In this digital age, people's dependence on electricity is also increasing. Whether in the household, industrial or commercial fields, a stable and reliable power supply is crucial. As an important electrical appliance for managing the transmission and use of electric energy, switches are widely used in various occasions. In a switch, the contact mechanism, as the actuator for closing and opening the circuit, is one of the most important components of the switch. The contact mechanism usually consists of a fixed static contact and a moving dynamic contact. Traditional switches mostly use an external auxiliary mechanism to judge the closing state of the contact, but this method occupies a large space and will increase the number of parts and costs. A small number of new switches have begun to use an internal auxiliary mechanism. Although it reduces the space occupation and costs, due to its proximity to the contact mechanism, the working process of the auxiliary mechanism and the dynamic contact may interfere with each other, affecting the normal operation.

[0033] To solve the above problems, an embodiment of the present application provides an auxiliary mechanism that can be applied inside a switch. As Figure 1 and Figure 2 shown, the auxiliary mechanism includes an auxiliary circuit. The auxiliary circuit has a closing contact 11, a tripping contact 12, and a moving contact 13. The moving contact 13 is installed on the operating handle 20. The operating handle 20 can be movably installed inside the housing of the switch. Thus, the operating handle 20 can drive the moving contact 13 to contact and cooperate with the closing and tripping contacts 12 while driving the dynamic contact to cooperate with the static contact for closing and opening, so that the auxiliary circuit outputs corresponding signals. Of course, the present application does not limit the movable installation method of the operating handle 20. For example, it can be rotatably installed on the housing of the switch or slidably installed on the housing of the switch. For the convenience of understanding, the following will be described schematically with the rotation of the operating handle 20 as an example.

[0034] Specifically, as Figure 1 and Figure 2As shown, the moving contact 13 has a first position in contact with the closing contact 11 and a second position in contact with the opening contact 12. By mounting the moving contact 13 on the operating handle 20, when the operating handle 20 is driven to rotate, the moving contact 13 can be driven to switch between the first position and the second position. When the moving contact 13 is in the first position, the auxiliary circuit outputs a closing signal; when the moving contact 13 is in the second position, the auxiliary circuit outputs an opening signal. Thus, it is ensured that the auxiliary circuit can output corresponding signals according to the contact between the moving contact 13 and the closing contact 11 or the opening contact 12, so as to accurately judge the on-off state of the switch. Secondly, by directly mounting the moving contact 13 on the operating handle 20, space is saved, the number of components is reduced, and the space utilization rate and cost are optimized. Furthermore, the switching of the moving contact 13 between the first and second positions can be achieved through the simple operation of the operating handle 20, making the control of the auxiliary circuit more convenient and efficient, and improving the overall performance of the switch. More importantly, the auxiliary mechanism is far from the contact mechanism, avoiding interference during the movement of the moving contact and ensuring the smooth operation of the moving contact, further improving the reliability and durability of the switch.

[0035] Optionally, the moving contact 13 also has a transition position where it is not in contact with either the closing contact 11 or the opening contact 12. When the moving contact 13 is in the transition position, the auxiliary circuit outputs a transition signal. The moving contact 13 is driven by the operating handle 20 to switch between the first position, the second position, and the transition position, ensuring real-time monitoring and feedback of the switch circuit state, as well as timely warning in case of possible faults.

[0036] When it is necessary to connect the circuit, the operating handle 20 drives the moving contact to close with the static contact, and at the same time drives the moving contact 13 to contact the closing contact 11. At this time, the auxiliary circuit immediately outputs a closing signal, transmitting the information that the switch is in the connected state to the user. This function not only provides immediate operation feedback but also ensures the reliability of the circuit connection.

[0037] Conversely, when it is necessary to disconnect the circuit or the switch fails, the operating handle 20 drives the moving contact to open with the static contact, and at the same time drives the moving contact 13 to contact the opening contact 12. At this time, the auxiliary circuit will output an opening signal, notifying the user that the switch is in the disconnected state or a fault has occurred and further inspection or repair is required. This real-time status feedback is crucial for the safe and stable operation of the switch.

[0038] In addition, when a fault occurs in the switch, during the process of the operating handle 20 driving the moving contact to move from the closed position to the open position, or from the open position to the closed position, the moving contact may also stay between the closed position and the open position. At this time, the operating handle 20 will also drive the moving contact 13 to stay at a transition position where it is not in contact with either the closing contact 11 or the opening contact 12. The auxiliary circuit can detect this transition state and output a corresponding transition signal. This design enables the user to promptly know the abnormal state of the switch and take necessary measures in a timely manner to handle or repair the fault, thereby minimizing the downtime and production losses to the greatest extent possible.

[0039] Optionally, as Figure 3 and Figure 4 shown, the auxiliary circuit is electrically connected to at least one signal terminal 30, and the signal terminal 30 is mounted on the circuit board 40. When there is one signal terminal 30, the input ports of the signal terminal 30 are respectively connected to the moving contact 13, the opening contact 12, and the closing contact 11. These connections ensure that the state changes and operating actions of the switch can be accurately captured under different operating states. At the same time, the output port of the signal terminal 30 is connected to an indicator light or an alarm, so that the state of the switch can be visually conveyed to the user or operator through visual or audible signals. When there are three signal terminals 30, the input ports of the three signal terminals 30 are connected to the moving contact 13, the opening contact 12, and the closing contact 11, and the output ports of the three signal terminals 30 are respectively connected to different indicator lights or alarms. The input ports of each signal terminal 30 respectively receive the state signals from different contacts of the switch. After being processed and analyzed by the auxiliary circuit, according to the current state of the switch, corresponding signals are output and are fed back in real time through the indicator lights or alarms connected to the corresponding output ports.

[0040] For example, when the output port of the signal terminal 30 is connected to an indicator light, when the moving contact 13 is in contact with the closing contact 11, that is, when the switch is in the on state, the indicator light may display green; when the moving contact 13 is in contact with the opening contact 12, that is, when the switch is in the off state, the indicator light may display red; and when the moving contact 13 is not in contact with either the closing contact 11 or the opening contact 12, that is, when the switch has a fault or other abnormal states, the indicator light does not light up. Through the change in color, the user can intuitively understand the actual operating state of the switch without in-depth analysis or inspection.

[0041] For another example, connect the output port of the signal terminal 30 to the alarm. When the moving contact 13 contacts the closing contact 11, that is, when the switch is in the on state, the alarm does not make a sound; when the moving contact 13 contacts the opening contact 12, that is, when the switch is in the off state, the alarm emits a continuous sound; and when the moving contact 13 does not contact either the closing contact 11 or the opening contact 12, that is, when the switch fails or is in other abnormal states, the alarm emits intermittent beeps. The alarm conveys information by sound, enabling the user to be aware of the abnormal situation of the switch without specifically monitoring the indicator light or other display devices.

[0042] Optionally, the auxiliary circuit further includes a positive power supply and a negative power supply. The positive power supply and the negative power supply are the basis of the entire circuit and provide the necessary power supply. The moving contact 13 is electrically connected to the positive power supply, and the closing contact 11 and the opening contact 12 are electrically connected to the negative power supply. The closing contact 11 and the opening contact 12 are connected in parallel. Thus, when the moving contact 13 contacts the closing contact 11, a first energized circuit can be formed. At this time, the current is drawn from the positive power supply, passes through the moving contact 13 and the closing contact 11 in sequence, and finally flows to the negative power supply. When the moving contact 13 contacts the opening contact 12, a second energized circuit can be formed. At this time, the current is drawn from the positive power supply, passes through the moving contact 13 and the opening contact 12 in sequence, and finally flows to the negative power supply. When the moving contact 13 does not contact either the closing contact 11 or the opening contact 12, at this time, the positive and negative power supplies cannot be conducted, that is, an energized circuit cannot be formed.

[0043] In other embodiments, the moving contact 13 can also be electrically connected to the negative power supply, and the closing contact 11 and the opening contact 12 are electrically connected to the positive power supply. In these two configuration methods, regardless of whether the moving contact 13 is connected to the positive power supply or the negative power supply, the closing contact 11 and the opening contact 12 are both connected to the corresponding power pole, and different circuits are controlled to be conducted and disconnected through different contacts of the moving contact 13. This design enables the auxiliary circuit to effectively control the generation of signals according to the state change of the switch, thereby realizing the monitoring and feedback of the switch state.

[0044] Optionally, as Figure 3 and Figure 4As shown, the auxiliary mechanism further includes a circuit board 40. The auxiliary circuit further includes a first conductive elastic piece 51, a second conductive elastic piece 52 fixedly mounted on the circuit board 40 by welding or the like, and a third conductive elastic piece 53 mounted on the operating handle 20 by plugging or snapping or the like. The closing contact 11 is located on the first conductive elastic piece 51, the opening contact 12 is located on the second conductive elastic piece 52, and the moving contact 13 is located on the third conductive elastic piece 53, realizing the position positioning and electrical connection of the closing contact 11, the opening contact 12 and the moving contact 13. The circuit board 40, as the basis for supporting and connecting the first conductive elastic piece 51 and the second conductive elastic piece 52, not only provides physical support, but also effectively manages the wiring and connection between various components in the circuit, optimizing the space utilization of the switch and the conduction efficiency of the circuit to the greatest extent.

[0045] Specifically, when the moving contact 13 contacts the closing contact 11, the formed first energized circuit leads out from the positive pole of the power supply, passes through the third conductive elastic piece 53, the moving contact 13, and the closing contact 11 in sequence, and finally returns to the negative pole of the power supply through the first conductive elastic piece 51. Conversely, when the moving contact 13 contacts the opening contact 12, the second energized circuit starts. Similarly, current is led out from the positive pole of the power supply, passes through the third conductive elastic piece 53, the moving contact 13, and the opening contact 12, and finally returns to the negative pole of the power supply through the second conductive elastic piece 52. This design ensures that when the moving contact 13 is in different positions, current can smoothly pass through all necessary contacts to form a reliable energized circuit.

[0046] Optionally, as Figure 3 and Figure 4 shown, the auxiliary circuit further includes a fourth conductive elastic piece 54 mounted on the circuit board 40 by welding or the like. The third conductive elastic piece 53 abuts against the fourth conductive elastic piece 54. The third conductive elastic piece 53 is fixed on the operating handle 20 and moves with the movement of the operating handle 20. The fourth conductive elastic piece 54 is fixed on the circuit board 40 and is connected to the positive pole of the power supply. A key advantage of this design is that no matter how the operating handle 20 moves, the third conductive elastic piece 53 always remains in contact with the fourth conductive elastic piece 54, thus ensuring the continuous connection between the positive pole of the power supply and the third conductive elastic piece 53. This design simplifies the complexity of power connection. Specifically, only the positive pole of the power supply needs to be connected to the fourth conductive elastic piece 54 fixedly mounted on the circuit board 40, without connecting a wire to the third conductive elastic piece 53 that needs to move. This reduces the problems of wire wear or breakage that may be caused by the movement of the moving contact 13, improving the durability and reliability of the switch.

[0047] In the specific implementation process, when the moving contact 13 contacts the closing contact 11, the formed first energized circuit is as follows: The current is led out from the positive pole of the power supply, conducted to the third conductive elastic sheet 53 through the fourth conductive elastic sheet 54, and then sequentially passes through the moving contact 13, the closing contact 11, and the first conductive elastic sheet 51, and finally flows to the negative pole of the power supply. Similarly, when the moving contact 13 contacts the opening contact 12, the second energized circuit is formed. The current still conducts from the positive pole of the power supply to the third conductive elastic sheet 53 through the fourth conductive elastic sheet 54, then passes through the moving contact 13 and the opening contact 12, and finally returns to the negative pole of the power supply through the second conductive elastic sheet 52. In summary, this auxiliary circuit design based on the fourth conductive elastic sheet 54 not only simplifies the power connection but also ensures the stability of current conduction and the reliability of the system.

[0048] Optionally, as Figure 5 and Figure 6 shown, the third conductive elastic sheet 53 is installed in the insertion slot 21 of the operating handle 20, ensuring a reliable connection between the third conductive elastic sheet 53 and the operating handle 20, enhancing the stability of the electrical connection, and avoiding connection problems that may be caused by the movement of the operating handle 20. The moving contact 13 is located on the third conductive elastic sheet 53, so that when the operating handle 20 moves, the moving contact 13 also moves accordingly, ensuring that it will not loosen or fall off during the movement process, and ensuring the effective switching of the moving contact 13 between the closing contact 11 and the opening contact 12. Moreover, by providing the insertion slot 21 on the operating handle 20, the installation of the third conductive elastic sheet 53 and the moving contact 13 is more compact, reducing the space occupied by the auxiliary mechanism and making the overall design of the switch more compact and efficient.

[0049] Optionally, as Figure 5 and Figure 6 shown, the third conductive elastic sheet 53 includes a receiving portion 531 for receiving the moving contact 13 and at least two pins 532 connected to opposite sides of the receiving portion 531. There is an included angle between the two pins 532, that is, the two pins 532 extend into the interior of the operating handle 20 in different directions respectively, so that the third conductive elastic sheet 53 can be firmly positioned in the insertion slot 21, and the stability and reliability of the pins 532 are ensured when the operating handle 20 moves. The design of the included angle provides both sufficient mechanical support and ensures that the stability of the electrical connection will not be affected by external forces or vibrations during the operation process. It should also be noted that during the process of the operating handle 20 driving the third conductive elastic sheet 53 to move, at least one of the two pins 532 should always be in contact with the fourth conductive elastic sheet 54 to ensure that the electrical connection between the power supply and the third conductive elastic sheet 53 is always stable and reliable.

[0050] An embodiment of the present application further provides a switch, which includes an operating handle 20, a moving contact, a static contact, and an auxiliary mechanism of any of the above. The moving contact and the static contact are responsible for the closing and opening operations of the main circuit, and the auxiliary mechanism is used to judge the on-off state of the main circuit. The operating handle 20 is respectively drivingly connected to the moving contact and the moving contact 13, so that in a single operation of the operating handle 20, it can drive the moving contact to contact or separate from the static contact while driving the moving contact 13 to contact the closing contact 11 of the auxiliary mechanism or the opening contact 12 of the auxiliary mechanism. Thus, both the connection or disconnection of the main circuit and the corresponding switching of the auxiliary circuit are completed. It should be understood that the switch can be a circuit breaker, a change-over switch, or other types of switches, and the embodiment of the present application does not limit the type of the switch. Since the switch adopts the above auxiliary mechanism, it also has the same beneficial effects as the auxiliary mechanism, which will not be elaborated here.

[0051] Optionally, as Figure 5 and Figure 6 shown, the third conductive elastic sheet 53 of the auxiliary mechanism includes a receiving portion 531 for receiving the moving contact 13 and at least two pins 532 connected to opposite sides of the receiving portion 531, and there is an included angle between the two pins 532. The operating handle 20 includes a mounting groove 22 for mounting the moving contact 13, and the size and shape of the mounting groove 22 match the size of the moving contact 13 to ensure that the moving contact 13 can be safely and firmly fixed on the operating handle 20. In addition, there is a plug-in groove 21 on each side of the mounting groove 22 for respectively plugging the two pins 532 of the third conductive elastic sheet 53. The shapes and sizes of these plug-in grooves 21 should match the design of the pins 532 to ensure that the pins 532 can be accurately inserted and firmly connected without loosening or falling off due to movement or operation. By setting suitable mounting grooves 22 and plug-in grooves 21 on the operating handle 20, the reliability and stability of the electrical connection are improved, and the layout and space utilization of the auxiliary mechanism are optimized, improving the overall compactness and efficiency of the switch.

[0052] Optionally, the switch further includes a housing and a linkage mechanism, and the operating handle 20 drives the moving contact to move through the linkage mechanism. The auxiliary mechanism, the contact mechanism, and the linkage mechanism are all arranged inside the housing, ensuring the compact structure, safety, and reliability of the entire switch. The design of the housing provides an external environment for protecting each mechanism, preventing each mechanism from being externally interfered or damaged.

[0054] The embodiments of the present application further provide a power distribution device, which applies the aforementioned switch to the power distribution device. The power distribution device can be applied to intelligent scenarios, intelligent usage scenarios and the Internet of Things industry to achieve intelligent scenario management.
