Mechanical locking components for non-mechanical interface electronic switches

Abstract

This invention provides a non-mechanical interface electronic switch or a mechanical interface electronic switch, which is controlled to modulate between an active and inactive state based on electronic activity. The switch includes a hole defining an opening in a housing, and the opening defines an insertion path. A transmitter transmits a signal along a signal path to a receiver. To control the non-mechanical interface electronic switch, a mechanical locking device with a protrusion is inserted along the insertion path through the opening of the hole. To control the mechanical interface electronic switch, a mechanical control member with the protrusion is movable to interrupt the signal. The invention also provides a method for locking the non-mechanical interface electronic switch using the mechanical locking device, and a method for locking the mechanical control member of the mechanical interface electronic switch using the mechanical locking device.

Description

Technical Field

[0001] This disclosure relates to interlocking devices and electronic switches. More specifically, this disclosure relates to mechanical interlocking devices for non-mechanical interface electronic switches. Background Technology

[0002] Electricity can be supplied from active devices (e.g., power sources) to passive devices (e.g., load sources). For example, a power plant can generate electricity; a power company can supply electricity to consumers through circuits (e.g., a power grid); and consumers can use one or more devices to convert electricity into energy to achieve various goals. Electricity consumers include residential consumers as well as commercial and industrial consumers.

[0003] Electronic switches play an indispensable role in the safe and efficient distribution of electrical power. For example, electronic switches can be used at any stage of power distribution to switch (e.g., modulate) circuits, thereby interrupting current or transferring current from one conductor to another. Electronic switches are used in a wide variety of applications, including residential, commercial, and industrial electrical applications, and any application that employs electricity. Electronic switches are particularly important in hazardous locations such as oil refineries, chemical and petrochemical plants, mining, food processing, corrosive and industrial processing facilities.

[0004] To separately prevent and allow access to and operation of certain electronic switches, mechanical interlocking devices can be selectively attached (e.g., locking and unlocking) to the electronic switches. Such mechanical interlocking devices can be used to selectively secure mechanically interface electronic switches with movable control components. However, because non-mechanically interface electronic switches do not have movable control components, such mechanical interlocking devices may be incompatible with them. Therefore, for the safe and efficient distribution of power, both mechanical interlocking devices for non-mechanically interface electronic switches and non-mechanically interface electronic switches incorporating mechanical interlocking devices are required.

[0005] In addition, some electronic switches use mechanical actuation to disengage mechanical contacts to interrupt or transfer current, while others use electrical actuation. Mechanical interlocking devices can be used to selectively secure mechanically actuated mechanical interface electronic switches. Electrically actuated mechanical interface electronic switches, and mechanical interlocking devices for selectively securing them, are still needed. Summary of the Invention

[0006] In one embodiment, the non-mechanical interface electronic switch includes an electronic switching mechanism disposed within a housing of the non-mechanical interface electronic switch. The electronic switching mechanism is configured to modulate the non-mechanical interface electronic switch between an active and inactive state. The non-mechanical interface electronic switch includes a hole defining an opening in the housing. The opening defines an insertion path extending from a first position outside the housing to a second position inside the housing. The non-mechanical interface electronic switch includes a receiver disposed within the housing. The receiver is configured to operate the electronic switching mechanism.

[0007] In another embodiment, a method for mechanically locking a non-mechanical interface electronic switch includes inserting a protrusion of a mechanical locking device through a hole defining an opening in the housing of the non-mechanical interface electronic switch. The protrusion is inserted along an insertion path extending from a first position outside the housing to a second position inside the housing. The method includes controlling an electronic switch mechanism disposed within the housing based on this insertion.

[0008] In another embodiment, the mechanical interface electronic switch includes an electronic switching mechanism disposed within a housing of the mechanical interface electronic switch. The electronic switching mechanism includes at least one semiconductor defining a non-mechanical electronic switch. The non-mechanical electronic switch is configured to switch the mechanical interface electronic switch between an active and inactive state based on electronic activity. The mechanical interface electronic switch includes a receiver disposed within the housing and a transmitter disposed within the housing. The transmitter is configured to transmit a signal along a signal path to the receiver. The mechanical interface electronic switch includes a mechanical interface control component having a base portion located outside the housing and a protrusion located inside the housing. The base portion is movable between a first position in which the protrusion does not traverse the signal path and a second position in which the protrusion traverses the signal path.

[0031] Figure 1 This is a schematic front view of a package assembly 100 according to an embodiment of the present disclosure. In some embodiments, the package assembly 100 may include a package 101 having a cabinet 110. Additionally, in some embodiments, the package 101 may include a door 111 mounted relative to an opening in the cabinet 110 and oriented to allow and restrict access to the internal volume 115 of the cabinet 110 (see [link to documentation]). Figure 2 For example, the enclosure assembly 100 may include one or more of mechanical hinges, mechanical fasteners, mechanical latches, and other mounting hardware oriented to mount the door 111 relative to the opening of the cabinet 110. As shown, in some embodiments, the door 111 may include an optional viewing window 113.

[0032] Additionally, the enclosure assembly 100 may include a handle 120 operable to lock and unlock a door 111 of the cabinet 110. For example, in some embodiments, one or more fasteners (e.g., bolt locks, latches, buckles, hooks, bars, padlocks, key locks, combination locks) may be provided separately from or integrated with the handle 120 to secure the door 111 in a closed position relative to the opening of the cabinet 110, thereby firmly preventing unintended or unintentional access to the internal volume 115 of the cabinet 110. In some embodiments, the enclosure assembly 100 may be used for electrical distribution, and securing the door 111 in the closed position provides security to ensure the safe and efficient operation of the enclosure assembly 100 for power distribution. Similarly, in some embodiments, providing a handle 120 operable to secure the door 111 of the cabinet 110 provides security, operability, and predictability regarding the interaction of one or more users with one or more features of the enclosure assembly 100.

[0033] Figure 2 It shows Figure 1 The enclosure assembly 100, wherein the door 111 has been removed for clarity. In the illustrated embodiment, the cabinet 110 includes an inner surface 112 defining an internal volume 115 of the cabinet 110. Various components can be housed within the internal volume 115 of the cabinet 110. For example, in Figure 2 In the illustrated embodiment, the internal volume 115 of the cabinet 110 includes a plurality of electronic switches 200. The electronic switches 200 play an indispensable role in the safe and efficient distribution of power.

[0034] For purposes of explanation and not limitation, in some embodiments, electricity can be supplied from an active device (e.g., a power source) to a passive device (e.g., a load source). For example, a power plant can generate electricity; a power company can supply electricity to consumers through a circuit (e.g., a power grid); and consumers can use one or more devices to convert electricity into energy to achieve various goals. Electricity consumers include residential consumers as well as commercial and industrial consumers. The electronic switch 200 according to embodiments of this disclosure can be used at any stage of power distribution to modulate the circuit, thereby interrupting current or transferring current from one conductor to another.

[0035] One aspect of power distribution using one or more electronic switches 200 according to embodiments of this disclosure may include delivering power from producers to consumers, including industrial and commercial enterprises, residences, and individuals. Another aspect of power distribution may include stepping down (e.g., reducing) the transmission level voltage (e.g., from a power plant) to (e.g., at a distribution level voltage at a substation), and again stepping down the distribution level voltage to (e.g., at a service level voltage at the consumer). For example, one or more electronic switches 200 may be used individually or in conjunction with various electronic components (e.g., wires, capacitors, inductors, transformers, chokes, amplifiers, fuses, switches, connectors, detectors, sensors, transducers, resonators, semiconductors, cables, timers, vacuum tubes, suppressors, terminals, etc.) oriented individually or in combination to provide one or more operations or functions relating to the distribution of power from, for example, one or more active devices to one or more passive devices.

[0036] Therefore, one or more electronic switches 200 can be used in a variety of applications, including consumer and residential electrical applications and any application that uses electricity. For purposes of explanation and not limitation, an electronic switch (e.g., an electronic switching device) is an electronic component that selectively switches a circuit to interrupt or transfer current. Electronic switches that are manually (e.g., by a user) or automatically (e.g., based on automatic changes in current) controlled are generally referred to as circuit breakers, while electronic switches that are controlled based on intentional predetermined voltage changes applied by a user are generally referred to as relays.

[0037] Regarding the switching mechanisms and functions of electronic switches, two types of electronic switches—mechanical-electronic switches and non-mechanical-electronic switches—are described and compared below. Furthermore, users can control electronic switches via mechanical and non-mechanical interfaces, as described below. For purposes of explanation and not limitation, electronic switches are described as switching between an active state and a deactivated state (e.g., modulation). It should be understood that one or more features of this disclosure can be used to modulate the electronic switch between more than two states (e.g., low-power state, medium-power state, high-power state, etc.). Similarly, unless otherwise specified, modulating the electronic switch between active and inactive states may include one or more states that are bypassed (e.g., skipped) and / or engaged during the modulation process, rather than directly modulating from an active state to an inactive state or directly modulating from an inactive state to an active state without an intervening state. In some embodiments, it may be advantageous to directly modulate the electronic switch from an active state to an inactive state or directly modulating from an inactive state to an active state without an intervening state. Therefore, such modulation is also within the scope of this disclosure.

[0038] A mechatronic switch, also known as an electromechanical switch, includes one or more movable parts to modulate a circuit. For example, some electromechanical switches include a coil of wire wound around a solenoid and a spring-loaded armature. The spring-loaded armature is hinged to a bracket and mechanically connected to one or more sets of contacts. During operation of the electromechanical switch, the spring-loaded armature and the one or more sets of contacts move (e.g., switch) between an active or energized state and a deactivated or de-energized state, thereby “making” or “disconnecting” the circuit. In some embodiments, the making or disconnecting of the circuit may correspond to the “on” or “off” state of the circuit. An electromechanical switch may also operate in response to an excessive electrical load that generates a thermal change in the switch, causing the spring-loaded armature and the one or more sets of contacts to switch between an active or energized state and a deactivated or de-energized state.

[0039] Non-mechanical electronic switches, known as solid-state switches, operate without moving parts to provide the same circuit switching function as electromechanical switches. For example, Figure 3 It shows in Figure 2 The view Figure 3 The image shows an enlarged schematic of an exemplary solid-state switch 300. In some embodiments, the solid-state switch 300 includes one or more semiconductors 305 (e.g., diodes, transistors, integrated circuits) configured to modulate the solid-state switch 300 between an active or energized state and a deactivated or deactivated state, thereby "making" or "breaking" a circuit. The semiconductors 305 of the solid-state switch 300 perform this switching function based on electronic activity without any moving parts. In response to an excessive electrical load, the solid-state switch 300 immediately modulates between an active or energized state and a deactivated or deactivated state, whereas some electromechanical switches (e.g., conventional thermal-magnetic circuit breakers) may require seconds, minutes, or hours to respond to the same load.

[0040] Electromechanical switches and solid-state switches 300 can offer different advantages and disadvantages based on various factors, including but not limited to the power rating used with the switch, the expected lifespan of the switch, the required switching speed and frequency of the switch, the operating environment of the switch, and the budget. Operating or controlling an electronic switch can refer to "tripping" (e.g., deactivating) and resetting (e.g., activating) the switch. Furthermore, electronic switches can be operated mechanically or electrically (e.g., controlled). Mechanically operated electronic switches, referred to as mechanical interface electronic switches, may include a mechanical switching mechanism (e.g., a lever) having a movable control element capable of operating to switch the electronic switch between an active and deactivated state. On the other hand, electrically operated electronic switches, referred to as non-mechanical interface electronic switches, can electrically modulate the electronic switch between an active and deactivated state (e.g., by applying current) without any movable control element.

[0041] This invention provides various embodiments of mechanical interlocking devices for selectively fixing (e.g., locking and unlocking) mechanically and electrically controlled electronic switches. While the mechanical interlocking device itself may be movable or may contain movable parts, for the purposes of this disclosure, the mechanical interlocking device is considered as a separate feature distinguished from movable and non-movable control components capable of operating to switch the electronic switch between an active and deactivated state. Therefore, the mobility or movability of one or more features of the mechanical interlocking device should not be equated with the mobility or movability of the various control components.

[0042] In some implementations, the movable control part of the mechanical interface mechanism of a mechanically operated switch can generate an electric arc or spark. When used in hazardous environments including, for example, flammable gases, the arc or spark of the movable control part of the mechanical interface mechanism can increase the likelihood of fire or explosion, thus creating a safety risk. Alternatively, because non-mechanical interface switches do not have movable control parts, they can reduce or eliminate the risk of fire or explosion that would otherwise be caused by the arc and spark of the movable control part of the mechanical interface mechanism in a hazardous environment.

[0043] For example, in a mechanically operated mechatronic switch (not shown) (also known as a mechanical interface mechatronic switch, or simply a mechatronic switch), the mechanical switching mechanism is operable to move a spring-loaded armature and one or more sets of contacts between an active state and a deactivated state. In an electrically operated mechatronic switch (not shown) (also known as a non-mechanical interface mechatronic switch or hybrid switch), an applied current (whether automatically applied or user-applied) generates a magnetic field that causes the spring-loaded armature and one or more sets of contacts to move between an active state and a deactivated state.

[0044] Electrically operated non-mechanical electronic switches (also known as non-mechanical interface solid-state switches, or simply solid-state switches) electrically modulate between active and deactivated states (e.g., by applying a voltage) without employing moving parts.

[0045] Figure 3 This is a schematic diagram of a solid-state switch 300, which schematically illustrates some of the internal electrical functions of the solid-state switch 300 for illustrative purposes and not for limitation. As schematically shown, applying a voltage 301 (whether automatically or user-applied) across the control terminals of the solid-state switch 300 causes electronic activity 303 and semiconductor 305 to control an electrical switch 304 electrically connected to a load circuit 302, thereby allowing the solid-state switch 300 to operate between an active and deactivated state without the use of movable parts. Furthermore, the solid-state switch 300 may include a housing 310 in which the electronic activity 303, semiconductor 305, and electrical switch 304 are disposed.

[0046] Additional or alternative land, such as Figure 4 As shown, for clarity, [the text has been removed]. Figure 3 As shown in some of the features, the solid-state switch 300 may include a capacitive button 315 to allow a user to manually operate the solid-state switch 300 by touching the capacitive button 315, thereby electrically switching the solid-state switch 300 between an active state and a deactivated state. Although in Figure 4 A single capacitive button 315 is shown, but in alternative embodiments (not shown), multiple buttons may be used. For example, a first button may be used to activate the switch, and a second button may be used to deactivate the switch. Additionally, although not shown, in some embodiments, one or more capacitive buttons may be used to operate a hybrid switch according to embodiments of the present disclosure.

[0047] Whether operated manually or automatically, the solid-state switch 300 can perform the same electrical switching functions as mechanical-interface mechatronic switches (e.g., electromechanical switches) and non-mechanical-interface mechatronic switches (e.g., hybrid switches) without moving parts. Furthermore, because the solid-state switch 300 has no moving parts, when used in hazardous environments, it reduces or eliminates the risk of fire or explosion that would otherwise be caused by arcing and sparking from moving parts. Therefore, by reducing or eliminating the risk of fire or explosion, the solid-state switch 300 achieves specific practicality in hazardous environments including those containing flammable gases.

[0048] Similarly, in some embodiments, the operation of the movement or switching mechanism of a mechatronic switch, whether a mechanical interface mechatronic switch (e.g., an electromechanical switch) or a non-mechanical interface mechatronic switch (e.g., a hybrid switch), can generate an electric arc or spark. When used in hazardous environments including, for example, flammable gases, the electric arc or spark of the movement or switching mechanism of the mechatronic switch can increase the likelihood of fire or explosion, thus creating a safety risk. However, in some embodiments, the movement or switching mechanism of a hybrid switch can be enclosed (e.g., sealed) within the switch housing, making the hybrid switch suitable for hazardous environments as well, since the movement or switching mechanism is enclosed within the housing and isolated from the hazardous environment.

[0049] Therefore, since non-mechanical interface switches do not have external moving control components, when used in hazardous environments, electrically operated mechanical switches (hybrid switches) and electrically operated non-mechanical switches (solid-state switches) employing non-mechanical interface technology can reduce or eliminate the risk of fire or explosion caused by arcs and sparks from the external moving control components of the mechanical interface mechanism of electronic switches.

[0050] However, one advantage of external motion control components is that they (e.g., mechanical interface mechanisms) can create tactile and visual indications for human users regarding whether an electronic switch is activated or deactivated. Conversely, because the solid-state switch 300 has no moving parts, it can provide the same tactile and visual impression regardless of whether it is activated or deactivated. Similarly, because the hybrid switch has no moving parts, it can also provide the same tactile and visual impression regardless of whether it is activated or deactivated. Therefore, human users interacting with mechanical interface switches can perceive the state of electromechanical switches visually or tactilely, while human users interacting with non-mechanical interface switches such as hybrid switches (not shown) or solid-state switch 300 may not be able to quickly perceive the switch's state.

[0051] In some implementations, the mechanical interlocking device 600 ( Figure 9 (As shown) tactile and visual indications can also be provided to human users to indicate whether the switch is locked or unlocked. For example, an electronic switch secured by a mechanical locking device can indicate that the switch is inactive or has been deactivated, while an unlocked electronic switch can indicate that the switch is active and that current may be present. Alternatively, in another embodiment, an electronic switch secured by a mechanical locking device can indicate that the switch is active and that current may be present, while an unlocked electronic switch can indicate that the switch is inactive or has been deactivated. Therefore, the mechanical locking device can prevent and limit unauthorized or unintentional operation of the electronic switch to which it is secured.

[0052] Known mechanical interlocking devices can be fixed to an external movable control component (e.g., a mechanical interface mechanism) of an electromechanical switch and provide tactile and visual indication of whether the mechanical interface switch is activated or deactivated. However, because non-mechanical interface switches do not have an external movable control component to control or operate the switch, known mechanical interlocking devices are incompatible with non-mechanical interface switches. Therefore, a mechanical interlocking device is needed for non-mechanical interface electronic switches. For example, a non-mechanical interface electronic switch (e.g., a hybrid switch and a solid-state switch 300) that can be selectively fixed (e.g., locked and unlocked) using a mechanical interlocking device is needed to restrict access to and allow access to and operation of the hybrid switch or solid-state switch 300.

[0053] Furthermore, the non-mechanical interface switch and associated mechanical interlocking device 600 according to embodiments of the present disclosure are implemented without the need for external moving control components that could cause arcing or sparking. Therefore, the non-mechanical interface electronic switches (e.g., hybrid switches and solid-state switches 300) and associated mechanical interlocking devices 600 of the present disclosure are safe for use in hazardous environments and provide a specific practicality according to embodiments of the present disclosure that would otherwise be impossible to achieve with electronic switches that do not include one or more features.

[0054] Features and methods of a mechanical interlocking device 600 for non-mechanical interface electronic switches (e.g., hybrid switches and solid-state switches) will now be described with reference to an exemplary embodiment of a solid-state switch 300. Therefore, unless otherwise stated, it should be understood that one or more features of the mechanical interlocking device 600 and the solid-state switch 300 may be provided individually or in combination to provide the same or similar advantages relative to other types of non-mechanical interface electronic switches (including hybrid switches), as described above.

[0055] Figure 5 A front view schematically shown is an exemplary solid-state switch 300 configured for a mechanical locking device 600 according to an embodiment of the present disclosure. In some embodiments, the housing 310 of the solid-state switch 300 may include an aperture 500 defining an opening in the housing 310. Reference Figures 6 to 19 Various exemplary embodiments of the solid-state switch 300 are disclosed. Unless otherwise specified, it should be understood that one or more features of the exemplary embodiments may be provided individually or in combination to provide features and methods of a mechanical locking device 600 for non-mechanical interface electronic switches (e.g., hybrid switches and solid-state switches) according to embodiments of the present disclosure.

[0056] Figure 6 It shows along Figure 5 The cross-sectional view of an exemplary embodiment of the solid-state switch 300 is taken by line 6-6. The opening of the hole 500 defines an insertion path 505 extending from a position 309 outside the housing 310 to a position 311 inside the housing 310. Figure 7 and Figure 8 The following are shown respectively along Figure 5 The figures 7-7 and 8-8 show cross-sectional views of the solid-state switch 300. In the illustrated embodiment, the hole 500 includes a first hole 501 and a second hole 502, each hole defining a corresponding opening that defines a corresponding insertion path 505 extending from a location 309 outside the housing 310 to a location 311 inside the housing 310. Although two holes 501, 502 are shown, in some embodiments, a single hole defining an insertion path may be provided. Similarly, in some embodiments, more than two holes defining more than two insertion paths may be provided without departing from the scope of this disclosure.

[0057] Back Figure 6The solid-state switch 300 may include a transmitter 510 and a receiver 520. The transmitter 510 and receiver 520 are disposed within a housing 310 of the solid-state switch 300, at a location 311 inside the housing 310. The transmitter 510 is configured to transmit a signal 525 along a signal path 515 extending from the transmitter 510 to the receiver 520, and the receiver 520 is configured to receive the transmitted signal 525. An insertion path 505 and the signal path 515 are transversely intersected. In the illustrated embodiment, the signal 525 is transmitted through an aperture 500 along the signal path 515, and the insertion path 505 extends through the aperture 500 and transverses the signal path 515 at location 311 within the housing 310 of the solid-state switch 300. Although shown as a linear path, in other embodiments, the insertion path 515 may be non-linear and may extend at one or more angles relative to the opening of the aperture 500.

[0058] Transmitter 510 and receiver 520 may include various components oriented to transmit and receive signal 525. In some embodiments, transmitter 510 is an electromagnetic transmitter configured to transmit signal 525 as electromagnetic radiation, and receiver 520 is an electromagnetic receiver. Electromagnetic signal 525 may be defined as various wavelengths relative to the electromagnetic spectrum. For example, transmitter 510 may be a light-emitting diode (LED) configured to transmit optical signal 525, and receiver 520 may be a photodiode that converts optical signal 525 into current. Optical signal 525 may be defined as various wavelengths, including visible light and infrared (IR) light.

[0059] In other embodiments, transmitter 510 is a magnet configured to transmit signal 525 as a magnetic field, and receiver 520 is a sensor. Transmitter 510 and receiver 520 may operate based on the Hall effect, defined as the voltage difference (Hall voltage) that generates a current transverse to the conductor and is transverse to a magnetic field applied perpendicular to that current. For example, transmitter 510 and receiver 520 may be configured to detect based on mechanical locking device 600 (see...). Figure 9 The change in magnetic field caused by the presence or absence of solid-state switch 300.

[0060] In another embodiment, transmitter 510 and receiver 520 may operate based on the piezoelectric effect, which is defined as the ability of certain materials to generate an electric charge in response to applied mechanical stress. For example, transmitter 510 and receiver 520 may be configured to detect based on mechanical locking device 600 (see...). Figure 9 At least one of the voltage difference and voltage differential resulting from the presence or absence of the solid-state switch 300.

[0061] like Figure 7As shown, in some embodiments, the transmitter 510 may be positioned on one side of the aperture 500 (e.g., below the aperture 500). Figure 8 As shown, in some embodiments, receiver 520 may be positioned opposite transmitter 510 on the other side of the aperture (e.g., above aperture 500). Therefore, referring back to... Figure 6 Signal 525 is transmitted from transmitter 510 on one side of aperture 500 along signal path 515 to receiver 520 on the other side of aperture 500, opposite transmitter 510. In some embodiments, transmitter 510 and receiver 520 are positioned on opposite sides of aperture 500 such that signal path 515 and insertion path 505 can be transversely intersected.

[0062] In another embodiment, the relative positioning of the transmitter 510 and receiver 520 may vary as the transmitter 510 and receiver 520 are positioned within the housing 310, such that the receiver 520 is oriented to directly receive the signal 525 emitted by the transmitter 510. For example, the transmitter 510 may emit the signal 525 directly (e.g., without reflection or deflection) or indirectly (e.g., with reflection or deflection) to the receiver 520. Furthermore, the signal 525 may comprise a plurality of signals, one or more of which are emitted along a plurality of signal paths. The signal 525 may have a variety of widths and dimensions and, unless otherwise specified, is not intended to be limited to a single linear narrow beam as schematically shown in the figures.

[0063] Figure 9 The illustration schematically shows a device including an exemplary mechanical locking device 600. Figure 7 An alternative view of the cross-sectional view of the solid-state switch 300. Figure 9 In the diagram, the mechanical locking device 600 is schematically shown as a padlock 601 having a protrusion 610 and a body 620. Figure 10 An alternative embodiment of the mechanical locking device 600, including a folding locking latch 602, is provided. The folding locking latch 602 includes a pivoting fastener defining a protrusion 610 of the mechanical locking device 600 and a handle portion defining a body 620 of the mechanical locking device 600. The handle portion of the locking latch 602 can accommodate multiple additional locking mechanisms, including but not limited to one or more padlocks 601. Therefore, the locking latch 602 allows multiple users to add or remove multiple locking mechanisms from the mechanical locking device 600. In such an embodiment, the locking latch cannot be removed until each padlock has been removed from the locking latch 602, thereby ensuring that each user clears the associated electronics before the switch 300 can be activated.

[0064] Unless otherwise stated, the mechanical locking device 600 may include various fasteners (e.g., bolt locks, latches, snaps, hooks, bars, padlocks, key locks, combination locks, cables, etc.) having a body portion 620 and one or more protrusions 610. In some embodiments, the mechanical locking device 600 may include an integrated locking mechanism (e.g., a padlock 601). Additionally or alternatively, the mechanical locking device 600 may include a structure (e.g., a locking snap 602) oriented to receive a locking mechanism (e.g., a padlock 601). Furthermore, in some embodiments, the mechanical locking device 600 may include one or more features that define a device compatible with or conforming to specific security standards, including but not limited to a "locking mark" process.

[0065] like Figure 11 As shown, this figure provides Figure 6 In an alternative embodiment of the cross-sectional view of the solid-state switch 300, one or more protrusions 610 of the mechanical locking device 600 are oriented to insert into and pass through the hole 500, such that at least a portion of the one or more protrusions 610 blocks the transmission of a signal 525 from the transmitter 510 to the receiver 520. Additionally, when the one or more protrusions 610 are inserted into and pass through the hole 500, the main body portion 620 of the mechanical locking device 600 is accessible from outside the housing 310 of the solid-state switch 300.

[0066] As relative to Figures 12 to 19 Discussed in more detail, the mechanical interlocking device 600 can be selectively fixed (e.g., locked and unlocked) to the solid-state switch 300 to prevent and allow access to and operation of the solid-state switch 300, respectively. The mechanical interlocking device 600 provides a tactile and visual indication to the human user whether the solid-state switch 300 is activated or deactivated. Furthermore, the solid-state switch 300 and the mechanical interlocking device 600 are implemented without any moving parts that could cause an electric arc or spark. For example, while the mechanical interlocking device 600 may include moving parts (e.g., a locking mechanism), such parts move relatively slowly and have very little friction, making an electric arc or spark based on the movement of the mechanical interlocking device 600 unlikely when it is powered (e.g., electrically connected to a motor). Additionally, the mechanical interlocking device 600 may be made of a material that reduces or prevents electrostatic discharge. The solid-state switch 300 and the associated mechanical interlocking device 600 reduce or prevent potential ignition sources and are therefore safe for use in hazardous environments.

[0067] Figures 12 to 19 A portion of a solid-state switch 300 according to an embodiment of the present disclosure is illustrated schematically, including a method of locking the solid-state switch 300 using a mechanical locking device 600. For example, Figure 12 , Figure 14 , Figure 16 and Figure 18 An exemplary embodiment of a solid-state switch 300 provided in a powered or activated state is schematically shown, wherein circuit 700 is electrically active 701 (e.g., operating or "resetting"). In some embodiments, Figure 12 , Figure 14 , Figure 16 and Figure 18 The solid-state switch 300 is configured to correspond to a scenario where power is supplied to a machine (not shown) and the machine is operating.

[0068] On the contrary, Figure 13 , Figure 15 , Figure 17 and Figure 19 An exemplary embodiment of a solid-state switch 300 provided in a power-off or deactivated state is schematically shown, wherein the circuit 700 is a non-electrically active 702 (e.g., no operation or "tripped"). In some embodiments, Figure 13 , Figure 15 , Figure 17 and Figure 19 The solid-state switch 300 is configured to accommodate scenarios where no power is supplied to the machine and the machine is inactive. When the machine is inactive and there is no risk of electric shock, maintenance, repair, inspection, and other interactions with the machine can be performed. Therefore, the solid-state switch 300 and the mechanical interlocking device 600 provide a reliable and predictable way for various users to safely activate and deactivate the solid-state switch 300 and enhance safety.

[0069] like Figure 12 As shown, transmitter 510 transmits signal 525 along signal path 515 to receiver 520. When receiver 520 receives signal 525, circuit 700 is active 701 and solid-state switch 300 is energized. However, as Figure 13 As shown, if receiver 520 does not receive signal 525, circuit 700 is inactive 702 and solid-state switch 300 is de-energized.

[0070] For example, one or more protrusions 610 of the mechanical locking device 600 are oriented to insert along the insertion path 505 and through the hole 500, such that at least a portion of the one or more protrusions 610 traverses the signal path 515, thereby blocking the transmission of signal 525 from transmitter 510 to receiver 520. Because one or more protrusions 610 of the mechanical locking device 600 (e.g., partially or completely) block signal 525, receiver 520 (e.g., partially or completely) does not receive signal 525. Therefore, based on the application of the mechanical locking device 600 to the solid-state switch 300, circuit 700 is inactive 702 and solid-state switch 300 is de-energized.

[0071] Additionally, when one or more protrusions 610 are inserted into and pass through the hole 500, the main body 601 of the mechanical locking device 600 can be accessed from outside the housing 310 of the solid-state switch 300. For example, the mechanical locking device 600 can be secured (e.g., locked) and released (e.g., unlocked) from outside the housing 310 of the solid-state switch 300. When the mechanical locking device 600 is secured to the solid-state switch 300, the protrusions 610 block the signal 525, the receiver 520 does not receive the signal 525, and the solid-state switch 300 is de-energized. When the mechanical locking device 600 is released from the solid-state switch 300, the protrusions 610 no longer block the signal 525, the receiver 520 receives the signal 525, and the solid-state switch 300 is re-energized.

[0072] In some embodiments, the operation of the solid-state switch 300 may be reversed without departing from the scope of this disclosure. For example, in some embodiments (not shown), the transmitter 510 and receiver 520 may be configured such that when receiver 520 receives signal 525, circuit 700 is inactive (702) and solid-state switch 300 is de-energized. Similarly, in some embodiments (not shown), the transmitter 510 and receiver 520 may be configured such that when receiver 520 does not receive signal 525, circuit 700 is active (701) and solid-state switch 300 is energized.

[0073] Furthermore, unless otherwise stated, the specific positions of the transmitter 510 and receiver 520 relative to the aperture 500 are not limited to the embodiments shown in the figures. For example, refer to... Figure 12 and Figure 13 In some embodiments (not shown), without departing from the scope of this disclosure, the transmitter 510 may be positioned at the indicated location of the receiver 520 (e.g., above the aperture 500), and the receiver 520 may be positioned at the indicated location of the transmitter 510 (e.g., below the aperture 500).

[0074] Figure 14 and Figure 15 Alternative embodiments of a solid-state switch 300 including a structure 530 having a reflective surface 535 are provided. In the illustrated embodiment, the reflective surface 535 faces the transmitter 510 and the receiver 520. The reflective surface 535 is oriented to reflect a signal 525 from the transmitter 510 along a signal path 515 to the receiver 520. Unless otherwise stated, multiple reflective surfaces (not shown) may be provided to reflect a signal 525 from the transmitter 510 along a signal path 515 to the receiver 520 without departing from the scope of this disclosure.

[0075] like Figure 14As shown, transmitter 510 transmits incident signal 526 along signal path 515 to reflective surface 535 of structure 530. Incident signal 526 is reflected from reflective surface 535 and travels as reflected signal 527 along signal path 515 to receiver 520. When receiver 520 receives reflected signal 527, circuit 700 is active 701 and solid-state switch 300 is energized. However, as... Figure 15 As shown, if the receiver 520 does not receive the reflected signal 527, then the circuit 700 is inactive 702 and the solid-state switch 300 is de-energized.

[0076] For example, one or more protrusions 610 of the mechanical locking device 600 are oriented to insert along the insertion path 505 and through the hole 500, such that at least a portion of the one or more protrusions 610 bisects the signal path 515, thereby blocking the transmission of signal 525 from transmitter 510 to receiver 520. For example, at least a portion of the one or more protrusions 610 blocks at least one of the incident signal 525 and the reflected signal 527.

[0077] Because one or more protrusions 610 of the mechanical interlocking device 600 (e.g., partially or completely) block at least one of the incident signal 525 and the reflected signal 527, the receiver 520 (e.g., partially or completely) does not receive the reflected signal 527. Therefore, based on the application of the mechanical interlocking device 600 to the solid-state switch 300, the circuit 700 is inactive 702 and the solid-state switch 300 is de-energized.

[0078] exist Figure 16 In yet another alternative embodiment shown, the solid-state switch 300 may include a receiver 520 disposed within the housing 310. Furthermore, as Figure 17 As shown, the mechanical locking device 600 may include a transmitter 510 configured to communicate with a receiver 520. For example, one or more protrusions 610 of the mechanical locking device 600 may include the transmitter 510. The transmitter 510 may be attached to or integrated with the mechanical locking device 600. Additionally, one or more protrusions 610 including the transmitter 510 are oriented to insert along an insertion path 505 and through a hole 500. When one or more protrusions 610 including the transmitter 510 are inserted, the transmitter 510 is configured to transmit a signal 525 along a signal path 515 extending from the transmitter 510 to the receiver 520, and the receiver 520 is configured to receive the transmitted signal 525.

[0079] In some implementation schemes, such as Figure 16 As shown, if receiver 520 does not receive signal 525, then circuit 700 is active 701 and solid-state switch 300 is energized. Conversely, as Figure 17 As shown, when receiver 520 receives signal 525, circuit 700 is inactive (702) and solid-state switch 300 is de-energized. Therefore, based on applying mechanical locking device 600 including transmitter 510 to solid-state switch 300 including receiver 520, circuit 700 is inactive (702) and solid-state switch 300 is de-energized.

[0080] Additionally, when one or more protrusions 610, including the transmitter 510, are inserted and pass through the hole 500, the main body 601 of the mechanical locking device 600 can be accessed from outside the housing 310 of the solid-state switch 300. For example, the mechanical locking device 600 can be secured (e.g., locked) and released (e.g., unlocked) from outside the housing 310 of the solid-state switch 300. When the mechanical locking device 600 is secured to the solid-state switch 300, the transmitter 510 of the protrusion 610 transmits a signal 525 to the receiver 520, and the solid-state switch 300 is de-energized. When the mechanical locking device 600 is released from the solid-state switch 300, the transmitter 510 of the protrusion 610 no longer transmits the signal 525 to the receiver 520, and the solid-state switch 300 is energized.

[0081] In some embodiments, the operation of the solid-state switch 300 may be reversed without departing from the scope of this disclosure. For example, in some embodiments (not shown), the transmitter 510 and receiver 520 may be configured such that when receiver 520 receives signal 525, circuit 700 is active 701 and solid-state switch 300 is energized. Similarly, in some embodiments (not shown), the transmitter 510 and receiver 520 may be configured such that when receiver 520 does not receive signal 525, circuit 700 is inactive 701 and solid-state switch 300 is de-energized.

[0082] Furthermore, unless otherwise stated, the specific position of the transmitter 510 on the protrusion 610 and the specific position of the receiver 520 relative to the hole 500 and the transmitter 510 are not limited to the embodiments shown in the drawings. For example, refer to Figure 16 and Figure 17 In some embodiments (not shown), without departing from the scope of this disclosure, the transmitter 510 may be disposed at various locations relative to the protrusion 610, and the receiver 520 may be disposed at various locations wherein the receiver 520 is configured to receive the signal 525 directly or indirectly from the transmitter 510.

[0083] Figure 18 and Figure 19Alternative embodiments of the solid-state switch 300 are provided, which include a structure 530 having a reflective surface 535 attached to or otherwise integrated into a protrusion 610 of a mechanical locking device 600. In the illustrated embodiment, the reflective surface 535 faces both the transmitter 510 and the receiver 520. The reflective surface 535 is oriented to reflect a signal 525 from the transmitter 510 along a signal path 515 to the receiver 520. Unless otherwise stated, multiple reflective surfaces (not shown) may be provided to reflect the signal 525 from the transmitter 510 along a signal path 515 to the receiver 520 without departing from the scope of this disclosure. Furthermore, in some embodiments, the reflective surface 535 may be integral with the protrusion 610 (e.g., the protrusion itself may be reflective) and should therefore not be considered limited to the separate structure 530 attached to the protrusion 610, as shown.

[0084] like Figure 19 As shown, transmitter 510 transmits incident signal 526 along signal path 515 to reflective surface 535 of structure 530. Incident signal 526 is reflected from reflective surface 535 and travels as reflected signal 527 along signal path 515 to receiver 520. When receiver 520 receives reflected signal 527, circuit 700 is inactive 702 and solid-state switch 300 is de-energized. However, as... Figure 18 As shown, if the receiver 520 does not receive the reflected signal 527, then the circuit 700 is active 701 and the solid-state switch 300 is energized.

[0085] For example, one or more protrusions 610 of the mechanical locking device 600 are oriented to insert along the insertion path 505 and through the hole 500, such that at least a portion of the reflective surface 535 transverses the signal path 515, thereby redirecting the signal 525 emitted from the transmitter 510 to the receiver 520. For example, as Figure 18 and Figure 19 As shown in the sequence, at least a portion of the reflective surface 535 redirects the incident signal 525 from the transmitter 510 as a reflected signal 527 to the receiver 520. Therefore, when the reflective surface 535 of the mechanical locking device 600 is in the insertion hole 500 of the protrusion 610 (e.g., partially or completely), it reflects the incident signal 525, thereby redirecting the reflected signal 527 (e.g., partially or completely) to the receiver 520. Therefore, based on the application of the mechanical locking device 600 to the solid-state switch 300, the circuit 700 is inactive 702 and the solid-state switch 300 is de-energized.

[0086] In another alternative embodiment (not shown), some or all of the protrusions may be made of a reflective material. In such an embodiment, the signal will pass obliquely through the reflective material and be redirected toward a receiver located on the opposite side of the transmitter.

[0087] The solid-state switch 300 and the mechanical interlocking device 600 provide a reliable and predictable way to safely activate and deactivate the solid-state switch 300 and improve safety. Therefore, the solid-state switch 300 and the mechanical interlocking device 600 can be used to provide safe and efficient power distribution.

[0088] Figure 20 and Figure 21 An embodiment of a mechanical interface non-mechanical electronic switch 800 (also referred to as a mechanical interface solid-state switch 800) is shown. Unless otherwise specified, the mechanical interface solid-state switch 800 includes the same features as the solid-state switch 300. For example, the mechanical interface solid-state switch 800 includes a mechanical interface control element 810. The mechanical interface control element 810 is shown as a lever 810. It should be understood that, without departing from the scope of this disclosure, in other embodiments, a button, toggle switch, knob, or other mechanical control element with a protrusion 820 movable between at least two different positions may be provided.

[0089] The mechanical interface control component 810 also includes a base portion 825, which is capable of being in a first unlocked position (e.g. Figure 20 (as shown) and the second locking position (as shown) Figure 21 The base portion 825 moves between the first unlocked position and the second locked position. The movement of the base portion 825 between the first unlocked position and the second locked position correspondingly causes the protrusion 820 to move between the first position (shown). Figure 20 (as shown) and second position ( Figure 21 The protrusion 820 moves between the various embodiments of the solid-state switch 300. As discussed above in conjunction with several embodiments of the solid-state switch 300, the movement of the protrusion 820 activates and deactivates the mechanical interface solid-state switch 800. Furthermore, any one or more features of the various embodiments of the solid-state switch 300 may be used alone or in combination with the mechanical interface control component 810. It should be understood that the protrusion 820 may function in the same or similar manner as the various protrusions 610 of the mechanical locking device 600 disclosed above.

[0090] The mechanical interface solid-state switch 800 may also include a latch 830 for selectively securing a mechanical locking device (e.g., mechanical locking device 600) thereto. For example, as Figure 21 As shown, the mechanical interface control component 810 can be positioned or moved to a locked position, and the base portion 825 can be selectively secured to the latch 830 using the mechanical locking device 600. When locked, the protrusion 820 interrupts the signal 525. Additionally, as... Figure 20As shown, after the base portion 825 is unlocked from the latch 830, the mechanical interface control component 810 can be positioned or moved to the locked position. When unlocked, the protrusion 820 does not interrupt the signal 525. The mechanical interface control component 800, alone or in combination with the mechanical interlock device 600, provides the human user with tactile and visual indications as to whether the mechanical interface solid-state switch 800 is activated or deactivated.

[0091] The use of the terms "includes" or "including" in the specification or claims is intended to be inclusive in a manner similar to the term "comprising," as interpreted when the term is used as a transition word in the claims. Similarly, the use of the term "or" (e.g., A or B) is intended to mean "A or B or both." The term "A or B only but not both" will be used when the applicant intends to indicate "only A or B but not both." Therefore, the use of the term "or" herein is inclusive, not exclusive. See Bryan A. Garner, Dictionary of Modern Legal Usage 624 (2nd ed., 1995). Furthermore, the use of the terms "in" or "to" in the specification or claims is intended to also mean "on" or "to". Similarly, the use of the term "connected" in the specification or claims is intended to mean not only "directly connected" but also "indirectly connected," such as connected via another component or part.

[0092] While this disclosure has been described through the description of embodiments thereof, and while the embodiments have been described in considerable detail, the applicant does not intend to limit the scope of the appended claims or in any way restrict it to such details. Additional advantages and modifications will readily occur to those skilled in the art. Therefore, this disclosure is not, in its broader aspects, limited to the specific details shown and described, representative systems and methods, and illustrative examples. Consequently, deviations from such details may be made without departing from the spirit or scope of the applicant's general inventive concept.
