Description

Technical Field

[0001] The present invention belongs to the technical field of switches and relates to a switch device with a matrix multi-way switch and the matrix multi-way switch. Background Art

[0002] The operating mechanism is a core component of a high-voltage switch. Its reliability plays a crucial role in ensuring accurate operation, so it undergoes various tests and inspections before leaving the factory. Due to differences among operating mechanism models, connectors are often used for wiring, and the number of pins and wiring positions often change. This results in testers frequently swapping pin positions during testing, such as switching pin 5 to pin 8, short-circuiting pins 2 and 7, and so on, making wiring complex. Complex wiring can easily lead to errors, resulting in burnout of electrical components. This can also necessitate the production of numerous conversion tooling for intermediate wiring, a significant pain point.

[0003] Existing operating mechanisms for run-in tests have multiple heavy-duty connectors. When the mechanism needs to be actuated, testers must run leads from the terminal block to the heavy-duty connectors. Due to the wide variety of operating mechanisms and varying customer requirements, these leads often need to be modified, requiring frequent repositioning of the lead pins and short-circuiting of different leads.

[0004] Existing multi-way switches and selector switches mostly offer single-input, single-output, multiple-input, multiple-output, single-input, multiple-location, and multiple-input, single-output functionality, often employing one or two of these options. Their structures are difficult to expand and cannot accommodate these four options. Once the structure is established, its functionality is limited, resulting in limited adaptability. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the existing operating mechanism has multiple heavy-load connectors, the wiring is cumbersome, the complicated wiring is prone to errors, resulting in burning of electrical components, and cannot meet the test requirements of different circuits. A switch device with a matrix multi-way switch and a matrix multi-way switch are provided.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A matrix multi-way switch includes a number of circuits that are cross-distributed with each other, and a circuit switch is set at each intersection;

[0008] Several mutually cross-distributed circuits include several input terminals and several output terminals. When the activation or deactivation of the circuit switch at the intersection is adjusted, the several input terminals and the several output terminals can be connected arbitrarily.

[0009] A further improvement of the present invention is:

[0010] Any one input end can be connected to any one or more output ends.

[0011] Any one input end can be connected to any one or more output ends.

[0012] A fuse is arranged at each of the input ends and output ends, and an indicator lamp is arranged on the fuse.

[0013] The circuit switch is a self-locking switch.

[0014] The plurality of mutually intersecting circuits include a plurality of rows and a plurality of columns of vertically intersecting circuits.

[0015] The plurality of mutually intersecting circuits include eight input ends.

[0016] The plurality of mutually intersecting circuits include eight output ends.

[0017] A switch device with a matrix type multi-way switch, comprising a multi-way switch control box, the matrix type multi-way switch is placed in the multi-way switch control box.

[0018] A multi-way input port and a multi-way output port are arranged on the multi-way switch control box, the multi-way input port is connected to the input end of the matrix type multi-way switch, and the multi-way output port is connected to the output end of the matrix type multi-way switch.

[0019] The multi-way input port is connected to the input end of the matrix type multi-way switch through a cable, and the multi-way output port is connected to the output end of the matrix type multi-way switch through a cable.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] The application discloses a matrix type multi-way switch, which comprises a plurality of mutually intersecting circuits, a circuit switch is arranged at each intersection, when the starting or closing of the circuit switch at the intersection is adjusted, the input end and the output end can be arbitrarily connected, so that the multi-pin contact of each switch can be connected and switched between a plurality of input ends and a plurality of output ends through simple on-off operation, without complex disassembly and assembly of the circuit, the circulation path of large current can be changed, the loop switching is achieved, the problems of circuit wear and poor contact caused by frequent disassembly and reconnection of the circuit in the traditional mode are avoided, and the service life of the circuit is prolonged; meanwhile, the probability of connection error of the circuit is reduced, the accuracy of the circuit connection is improved, and the stability of the secondary circuit operation is ensured.

[0022] Further, in the present application, any one input end can be connected to any one or more output ends, and multiple input ends can be connected to any one or more output ends. The convenient loop switching realized by the matrix switch is combined with the safety protection provided by the fuse, so that the operator can complete the operation more quickly and safely during the switching, multiplexing and changing of the secondary circuit large current loop.

[0023] Quick operation means that the circuit adjustment time is shortened, in the power system and other scenarios, the power outage time is reduced and even the operation without power outage can be realized, greatly improving the efficiency and continuity of power supply; safe operation reduces the safety risk faced by the operator and reduces the probability of safety accidents; the stability and reliability of the overall system are improved, and the related equipment and system based on the secondary circuit can also operate more efficiently and stably.

[0024] Further, in the present application, a fuse is arranged at each of the plurality of input ends and the plurality of output ends, and an indicator lamp is arranged on the fuse. When the loop has an overload or a short circuit leading to an abnormal increase in current, the fuse will quickly melt and cut off the circuit to prevent excessive current from flowing through the subsequent equipment and lines. Since the fuse cuts off the abnormal current in time, damage to the equipment caused by the large current impact is avoided, the key equipment in the secondary circuit is protected, and the equipment maintenance and replacement cost is reduced; the equipment can operate safely, and the reliability of the entire secondary circuit system is greatly improved, the system downtime caused by equipment failure is reduced, and the stable supply of power systems and the like is ensured.

[0025] The present application discloses a switching device with a matrix type multi-way switch. The switches are arranged in a matrix form, and each switch has multiple pin contacts. When a specific switch is operated, the connection between a specific input and output can be realized, providing a hardware basis for flexible switching and multiplexing of the loop. By controlling the on-off of different switches, the selection of large current can be realized. According to actual needs, the large current signal of a certain input can be directed to different output ends to meet the needs of different equipment or measurement points for current, thereby realizing the multiplexing function of the large current loop. When changing the loop, the traditional plug-in terminal needs to be manually plugged in and out, which is tedious and easy to damage the terminal and cable. It takes a long time to change each time, and on average it takes 15-30 minutes each time. The present application realizes the switching of the loop by matrix switch operation, and on average it only takes 1-2 minutes to change the loop each time, and the efficiency is improved significantly. At the same time, the traditional terminal cannot realize quick multiplexing, but the present application can easily realize loop multiplexing. The matrix switch layout is adopted, and the on-off of the switch realizes the convenient switching, multiplexing and changing of the secondary circuit large current loop without disassembling the line.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0037] In the description of the embodiments of the present invention, it should be noted that if the terms "upper," "lower," "horizontal," "inner," etc. appear, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the inventive product is typically placed when in use. These terms are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," etc. are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0040] The present invention is described in further detail below with reference to the accompanying drawings:

[0041] See also Figures 1 to 6 , an embodiment of the present invention discloses a matrix multi-way switch structure. The technical solution is to form a criss-cross network through a plurality of push button switches arranged in an array. The push button switch is located at the intersection of the rows and columns. The push button switch is self-locking and can remain open or closed. When closed, the green light is on, indicating that the contact is conductive, otherwise it is off. Secondly, a fuse with an indicator is provided in each row and column to achieve short-circuit protection, and the indicator light thereon indicates the power status of the corresponding row or column. When the button at the intersection of rows and columns is pressed, the button indicator light lights up, indicating that it has been transferred from the row to the corresponding cross column. Any input can be connected to any output, and multiple outputs can be achieved in one channel and multiple outputs in multiple channels.

[0042] The specific steps include:

[0043] Example 1

[0044] An embodiment of the present invention discloses a matrix multi-way switch, comprising a plurality of mutually cross-distributed circuits, with a circuit switch provided at each intersection; the plurality of mutually cross-distributed circuits include a plurality of input terminals and a plurality of output terminals, and when the activation or deactivation of the circuit switches at the intersections is adjusted, the input terminals and the output terminals can be connected arbitrarily.

[0045] Furthermore, in embodiments of the present invention, the term "matrix switch" refers to a switch structure organized or connected in a matrix configuration (rows and columns), typically used to describe the layout of a system, circuit, or mechanical structure. In a matrix structure, elements are arranged in alternating rows and columns, and the combination of rows and columns allows for the selection or control of specific elements.

[0046] Furthermore, in the embodiment of the present invention, the multi-way switch refers to a switching device that can select one or more outputs from multiple input signals, and switches input channels through control to achieve selection of different channels.

[0047] Furthermore, in an embodiment of the present invention, the circuit switch set at each intersection is specifically a self-locking button, which is displayed in green after startup. The self-locking button is a button switch with a locking function. After being pressed, it can remain in the on (or off) state without continuously applying external force. It will only return to the initial state after being operated again (such as pressing it again or manually resetting it).

[0048] Furthermore, the matrix multi-way switch disclosed in this embodiment is used in conjunction with an operating mechanism, which refers to a mechanism used to drive the action of a switch actuator, usually converting energy (such as electrical energy, mechanical energy, hydraulic energy) into mechanical motion to achieve operation and control of the equipment.

[0049] The embodiment of the present invention can conveniently realize the switching, reuse and modification of large current loops without disassembling the circuit, thereby improving the convenience, safety and flexibility of secondary circuit operation and reducing the time cost, safety risks and potential fault hazards caused by disassembling the circuit.

[0050] Example 2

[0051] An embodiment of the present invention discloses a matrix multi-way switch comprising a plurality of intersecting circuits, with a circuit switch disposed at each intersection. The plurality of intersecting circuits comprises a plurality of input terminals and a plurality of output terminals, and when the circuit switches at the intersections are activated or deactivated, the input terminals and the output terminals can be connected arbitrarily. The arbitrarily connected input terminals and output terminals include: any input terminal can be connected to any one or more output terminals, or multiple input terminals can be connected to any one or more output terminals.

[0052] Existing multi-way switches and selector switches mostly offer single-input, single-output, multiple-input, multiple-output, single-input, multiple-location, and multiple-input, single-output functionality, often employing one or two of these options. Their structures are difficult to expand and cannot accommodate these four options. Once the structure is established, its functionality is very limited, resulting in limited adaptability. This embodiment can accommodate all four of these options, with each mode selection performed manually at the touch of a button. The switch provides clear signal indication, short-circuit protection, and multiplexing.

[0053] Example 3

[0054] An embodiment of the present invention discloses a matrix multi-way switch, comprising a plurality of mutually cross-distributed circuits, with a circuit switch provided at each intersection; the plurality of mutually cross-distributed circuits include a plurality of input terminals and a plurality of output terminals, and when the activation or deactivation of the circuit switches at the intersections is adjusted, the input terminals and the output terminals can be connected arbitrarily; fuses are provided at the plurality of input terminals and the plurality of output terminals, and indicator lights are provided on the fuses, thereby combining the flexible operation of the matrix switch with the safety protection of the fuses, thereby improving the overall operating efficiency, stability, and safety of the secondary circuit.

[0055] Furthermore, in the embodiment of the present invention, a fuse is provided at the output end of the circuit, see Figure 1 In the LF1-LF8 series, when an abnormal condition such as an overload or short circuit causes excessive current in the circuit, the fuse quickly blows, shutting off the circuit and preventing damage to subsequent equipment and circuits. This design ensures the safety of the entire high-current circuit switching system and is essential for safe and reliable circuit changes.

[0056] Because the fuse cuts off the abnormal current in time, it avoids damage to the equipment caused by high current shock, protects key equipment in the secondary circuit, and reduces equipment maintenance and replacement costs; the equipment can operate safely, and the reliability of the entire secondary circuit system is greatly improved, reducing system downtime caused by equipment failure and ensuring the stable supply of systems such as electricity.

[0057] Example 4

[0058] An embodiment of the present invention discloses a matrix multi-way switch comprising a plurality of intersecting circuits, with a circuit switch disposed at each intersection. The intersecting circuits comprise a plurality of input terminals and a plurality of output terminals, and the input terminals and the output terminals can be connected arbitrarily by adjusting the activation or deactivation of the circuit switches at the intersections. The intersecting circuits comprise a plurality of rows and columns of circuits arranged vertically.

[0059] Example 5

[0060] An embodiment of the present invention discloses a matrix multi-way switch comprising a plurality of intersecting circuits, with a circuit switch disposed at each intersection. The intersecting circuits comprise a plurality of input terminals and a plurality of output terminals, and the input terminals and the output terminals can be connected arbitrarily by adjusting the activation or deactivation of the circuit switches at the intersections. The intersecting circuits comprise a plurality of rows and columns of circuits arranged vertically and intersecting each other. The intersecting circuits comprise eight input terminals and eight output terminals.

[0061] See also Figure 1 As can be seen in the circuit diagram, a large number of switches (E) are arranged in a matrix. By rationally designing the row and column combinations of switches, each switch has multiple pin contacts. When a specific switch is operated, a connection is established between a specific input (X1-X8) and an output (Y1-Y8). For example, to switch a high-current signal from input X3 to output Y5, the path is constructed by closing the corresponding switch in the matrix, thereby switching the high-current loop. This matrix structure provides the hardware foundation for flexible switching and multiplexing of loops.

[0062] Furthermore, in this embodiment, based on the aforementioned matrix switch layout, high current selection is achieved by controlling the on / off control of different switches. Based on actual needs, a high current signal from a given input can be directed to different output terminals to meet the current requirements of different devices or measurement points, thereby achieving high current loop multiplexing.

[0063] Example 6

[0064] See also Figures 2 to 5 An embodiment of the present invention discloses a switch device having a matrix multi-way switch, comprising a multi-way switch control box 2, wherein the matrix multi-way switch according to claim 1 is placed inside the multi-way switch control box 2; a multi-way input port 1 and a multi-way output port 3 are provided on the multi-way switch control box 2, wherein the multi-way input port 1 is connected to the input end of the matrix multi-way switch, and the multi-way output port 3 is connected to the output end of the matrix multi-way switch.

[0065] Furthermore, this embodiment also includes a first fuse 4 and a second fuse 6 with a power indicator. The first fuse is provided at each input terminal of the matrix multi-way switch, and the second fuse 6 is provided at each output terminal of the matrix multi-way switch. In the matrix multi-way switch, each intersection is provided with a self-locking push button switch 5.

[0066] Furthermore, in this embodiment, the multi-way input port 1 is connected to the input end of the matrix multi-way switch through a cable, and the multi-way output port 3 is connected to the output end of the matrix multi-way switch through a cable.

[0067] See also Figure 6During detection, the embodiment of the present invention can realize the requirements of switching circuits, multiplexing circuits and changing circuits, adjust the corresponding switches according to different circuit requirements, and realize circuit detection.

[0068] The convenient circuit switching achieved by the matrix switch combined with the safety protection provided by the fuse enables operators to complete operations more quickly and safely during the switching, reuse and change of high-current circuits in the secondary circuit.

[0069] Fast operation means shortening the circuit adjustment time. In scenarios such as power systems, it reduces the duration of power outages and even enables non-stop operation, greatly improving the efficiency and continuity of power supply; safe operation reduces the safety risks faced by operators and reduces the probability of safety accidents; the stability and reliability of the overall system are improved, which also enables related equipment and systems based on secondary circuits to operate more efficiently and stably. Compared with the existing technology, the present invention has achieved significant improvements in many aspects such as operational convenience, safety, and system stability.

[0070] Compared with traditional plug-in terminal block technology: Traditional plug-in terminal blocks require manual plugging and unplugging of wires when changing circuits, which is cumbersome and easy to damage terminals and cables. Each change takes a long time, an average of 15-30 minutes per change. The present invention uses matrix switch operation, and each circuit change only takes 1-2 minutes on average, significantly improving efficiency. At the same time, traditional terminal blocks cannot be quickly reused, while the present invention can easily achieve circuit reuse. In terms of safety, the fuse can effectively protect the circuit, while traditional terminal blocks do not have this protection mechanism.

[0071] Compared with microcontroller-based intelligent electronic switching technology, which has certain automation capabilities but is complex, costly, and requires high operator skills, the present invention has a relatively simple structure, manageable costs, and can be operated by ordinary technicians with simple training. In terms of reliability, intelligent electronic switches are susceptible to electromagnetic interference, while the matrix switch and fuse combination of the present invention can still operate stably in complex electromagnetic environments, ensuring the normal operation of the secondary circuit.

[0072] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
