[0001] The present application relates to the field of electrical technology, and in particular to a wiring device and electrical equipment. Background Art

[0002] Electrical equipment often has wiring terminals for connecting cables. In some electrical equipment, all terminals are exposed when the cover is removed, facilitating wiring and maintenance. However, if the equipment is powered on, there is a risk of accidental contact with the terminals, resulting in electric shock, compromising the safety of the equipment. Summary of the Invention

[0003] The embodiments of the present application provide a wiring device and electrical equipment that can improve safety protection.

[0004] In a first aspect, an embodiment of the present application provides a wiring device comprising a base and at least one wiring unit. Each wiring unit comprises at least two wiring assemblies and a movable part. Each of the wiring assemblies comprises a wiring terminal and a protective cover, wherein the wiring terminal is arranged on the base, the protective cover is movably connected to the base, and the protective cover is used to cover the wiring terminal. The movable part is movably connected to the base, and through the movement of the movable part relative to the base, the movable part can be connected to or disconnected from the protective cover of at least one of the wiring assemblies. The connection of the movable part to the protective cover of at least one of the wiring assemblies can keep the protective cover of at least one of the wiring assemblies covering the corresponding wiring terminal. The disconnection of the movable part from the protective cover of at least one of the wiring assemblies can enable the protective cover of at least one of the wiring assemblies to move relative to the base to be removed from the corresponding wiring terminal.

[0005] When the protective cover of at least one wiring assembly remains covering the corresponding wiring terminal, the wiring terminal of at least one wiring assembly is hidden in the base and the corresponding protective cover. In this way, users (including operators, etc.) cannot touch the wiring terminals, reducing the risk of electric shock to users and improving the safety protection of wiring devices and electrical equipment.

[0006] The protective cover of at least one wiring assembly can be removed from the corresponding wiring terminal, exposing the wiring terminal of the at least one wiring assembly. The exposed wiring terminal facilitates user wiring or maintenance (such as replacement).

[0007] Each terminal block in a wiring assembly is equipped with a dedicated protective cover. When wiring is required, the protective cover is removed from the terminal block, exposing the terminal. The protective covers of the remaining terminal blocks remain in place. Because the terminals of the unused terminals are covered by the protective covers, users cannot access the hidden terminals, reducing the risk of electric shock and further enhancing the safety of the wiring assembly and electrical equipment.

[0008] According to the first aspect, in a possible implementation of the first aspect of the present application, a slide groove is provided on the base, and the movable part includes a connecting part and a limiting part that are connected to each other, the connecting part is slidably connected to the slide groove, and the limiting part can move along with the connecting part. Through the movement of the movable part relative to the base, the limiting part can be connected to or disconnected from the protective cover of at least one of the wiring components.

[0009] The connecting portion is slidably connected to the slide groove, and the slide groove guides the movement of the connecting portion relative to the base body, thereby improving the smoothness of the movement of the movable part and facilitating the operation of the user.

[0010] According to the first aspect, in a possible implementation of the first aspect of the present application, the limiting portion includes a first limiting sub-portion and a second limiting sub-portion, the first limiting sub-portion is connected to the connecting portion, the second limiting sub-portion is connected to the connecting portion, the first limiting sub-portion and the second limiting sub-portion are spaced apart, and the first limiting sub-portion and the second limiting sub-portion are used to keep the protective cover of at least one wiring assembly covering the corresponding wiring terminal.

[0011] According to the first aspect, in a possible implementation of the first aspect of the present application, the at least two wiring assemblies include a first wiring assembly, a second wiring assembly, and a third wiring assembly arranged in sequence, and the first limiting sub-section and the second limiting sub-section are used to keep the protective covers of two of the first wiring assembly, the second wiring assembly, and the third wiring assembly covering the corresponding wiring terminals, and the wiring terminals of the first wiring assembly, the second wiring assembly, and the third wiring assembly have different polarities.

[0012] No matter what state the wiring unit is in, only a single protective cover can be opened, so that the wiring terminals of the wiring assembly of the opened protective cover can be tested or maintained.

[0013] According to the first aspect, in a possible implementation of the first aspect of the present application, a first measuring hole is provided on the second wiring assembly, and when the protective cover of the second wiring assembly covers the wiring terminal of the second wiring assembly, the first measuring hole is used to allow a probe to extend into and contact the wiring terminal of the second wiring assembly.

[0014] Voltage can be measured between the connection terminals of the second connection assembly and the connection terminals of the first connection assembly, and voltage can be measured between the connection terminals of the second connection assembly and the connection terminals of the third connection assembly.

[0015] According to the first aspect, in one possible implementation of the first aspect of the present application, each protective cover is provided with a first measurement hole, and each baffle is provided with at least one second measurement hole. When the second end of the baffle is connected to the second limiting sub-portion, each first measurement hole can be aligned with at least one second measurement hole by adjusting the position of the connecting portion relative to the base. The second measurement holes of the protective cover and baffle, combined with the position of the movable member, enable voltage measurement without opening each protective cover.

[0016] According to the first aspect, in a possible implementation of the first aspect of the present application, the at least two wiring assemblies include a first wiring assembly, a second wiring assembly, and a third wiring assembly, which are arranged in sequence. The wiring terminal of the first wiring assembly is a DC positive pole, the wiring terminal of the second wiring assembly is a neutral point, and the wiring terminal of the third wiring assembly is a DC negative pole. By arranging the positive pole, neutral point, and negative pole of the DC system at corresponding positions in the first wiring assembly, the second wiring assembly, and the third wiring assembly, respectively, the voltage between the positive pole or negative pole and the neutral point can be measured, preventing the measurement device from accidentally connecting between the positive and negative poles, causing high voltage damage to the device, thereby improving the reliability of the wiring device.

[0017] According to the first aspect, in a possible implementation of the first aspect of the present application, the at least two wiring assemblies include a first wiring assembly, a second wiring assembly, and a third wiring assembly arranged in sequence, the wiring terminal of the first wiring assembly is a first-phase AC pole, the wiring terminal of the second wiring assembly is a second-phase AC pole, and the wiring terminal of the third wiring assembly is a third-phase AC pole.

[0018] According to the first aspect, in a possible implementation of the first aspect of the present application, the protective cover of each wiring assembly is rotatably connected to the base so that the protective cover can be opened and closed relative to the base. The rotatable connection between the protective cover and the base facilitates reducing the volume occupied by the wiring device.

[0019] In a second aspect, an embodiment of the present application provides an electrical device, comprising a housing and the wiring device according to the first aspect, wherein the wiring device is fixed to the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1 , Figure 1 This is a schematic diagram of an application scenario of a photovoltaic system provided by the present application. The photovoltaic system includes a light array and a first electrical device. The photovoltaic array can be a photovoltaic module group. A photovoltaic module group can be composed of one or more photovoltaic strings connected in parallel, and a photovoltaic string can be obtained by connecting one or more photovoltaic modules in series. The photovoltaic modules here can be solar panels, photovoltaic panels, or energy storage batteries. The photovoltaic modules can be installed on a grounded metal frame. In other words, the grounded metal frame is a metal frame for installing photovoltaic modules, and the metal frame is grounded. In this embodiment, the first electrical device can be a photovoltaic inverter. The output current of the photovoltaic module can be input into the AC power grid or load for use after being inverted by the first electrical device.

[0028] The first electrical equipment includes a voltage stabilizing module, an inverter module and a connection module. The voltage stabilizing module is used to stabilize the DC voltage transmitted from the photovoltaic array. The inverter module is used to convert the DC voltage into AC voltage. The voltage stabilizing module, the inverter module and the connection module are all provided with wiring terminals. The wiring terminals of the voltage stabilizing module are connected to the wiring terminals of the connection module through cables, and the wiring terminals of the connection module are connected to the wiring terminals of the inverter module through cables, thereby realizing the electrical connection between the voltage stabilizing module and the inverter module. In this embodiment, the wiring terminals of the voltage stabilizing module, the inverter module and the connection module may include a positive pole (or positive line), a neutral pole (or neutral line) and a negative pole (or negative line).

[0029] In one possible implementation, the photovoltaic system also includes a second electrical device, which may be a junction box. The output current of the photovoltaic assembly can be converged by the second electrical device (i.e., multiple photovoltaic strings are connected in parallel to the junction box) to provide a DC input voltage for the first electrical device, and then converted into voltage and power by the photovoltaic inverter for use by the AC power grid or load. Terminals are provided on both the first electrical device and the second electrical device. The terminal on the second electrical device is electrically connected to the terminal on the first electrical device through a cable, and the terminal on the first electrical device is electrically connected to the inverter function module inside the first electrical device. The terminal on the second electrical device is electrically connected to the junction function module inside the second electrical device. The terminal on the first electrical device and the terminal on the second electrical device may include a positive pole and a negative pole.

[0030] The first and second electrical devices described above are used in DC systems. However, some electrical devices used in AC systems also have wiring terminals for electrical connections between different devices. In AC systems, the wiring terminals for the electrical devices include first-phase AC poles, second-phase AC poles, and third-phase AC poles.

[0031] When the outer cover of an electrical device with wiring terminals is removed (such as the first electrical device or the second electrical device), all the wiring terminals are exposed to facilitate wiring and maintenance. However, if the electrical device is not powered off, there is a risk of electric shock injury caused by accidental contact with the wiring terminals, which affects the safety protection of the electrical equipment. In addition, in some high-voltage scenarios, the voltage between some different wiring terminals exceeds the range of commonly used measuring instruments, and there is a risk of damage to the electrical equipment if the connection is incorrect. In addition, in DC systems such as photovoltaics and energy storage, there is currently an industry practice of increasing the DC voltage to reduce current and lower costs. However, when the system voltage exceeds 1500V, the standard defines it as a medium-voltage system, which has very strict requirements for safety regulations and design, and the cost also increases significantly. Therefore, some design schemes use a DC system with positive, negative and neutral poles, and it is necessary to ensure that the positive and negative poles with a voltage difference exceeding 1500V cannot be touched at the same time.

[0032] Based on this, the present application provides a wiring device and related electrical equipment to improve safety protection. A wiring device includes a base and at least one wiring unit. Each wiring unit includes at least two wiring assemblies and a movable part. Each of the wiring assemblies includes a wiring terminal and a protective cover, the wiring terminal is arranged on the base, the protective cover is movably connected to the base, and the protective cover is used to cover the wiring terminal. The movable part is movably connected to the base, and through the movement of the movable part relative to the base, the movable part can be connected to or disconnected from the protective cover of at least one of the wiring assemblies. The connection between the movable part and the protective cover of at least one of the wiring assemblies can keep the protective cover of at least one of the wiring assemblies covering the corresponding wiring terminal. The disconnection of the movable part from the protective cover of at least one of the wiring assemblies can enable the protective cover of at least one of the wiring assemblies to move relative to the base to be removed from the corresponding wiring terminal.

[0033] See also Figure 2 In a first embodiment of the present application, an electrical device is provided, comprising a housing 2 and a wiring device 1. The wiring device 1 is fixed to the housing 2, and the housing 2 is used to support and protect the wiring device 1. The electrical device may be a photovoltaic inverter, or other device provided with wiring terminals, such as a combiner box, an energy storage battery, a transformer, and the like.

[0034] The wiring device 1 includes a base 10 and at least one wiring unit 30 provided on the base 10. Each wiring unit 30 includes at least two wiring assemblies 32 and a movable part 34. Each wiring assembly 32 includes a wiring terminal 322 and a protective cover 324. The wiring terminal 322 is provided on the base 10. A circuit structure is provided on the base 10, and the wiring terminal 322 is electrically connected to the circuit structure of the base 10. The wiring terminal 322 is used to connect to a cable to realize the input and output of electrical signals of the base 10. The protective cover 324 is movably connected to the base 10, and the protective cover 324 is used to cover a corresponding wiring terminal 322 to prevent the user from accidentally touching the wiring terminal 322, thereby improving the safety and reliability of the wiring device 1.

[0035] The movable member 34 is movably connected to the base 10. By moving the movable member 34 relative to the base 10, the movable member 34 can be connected to or disconnected from the protective cover 324 of at least one wiring assembly 32. The movable member 34 is connected to the protective cover 324 of at least one wiring assembly 32, so that the protective cover 324 of at least one wiring assembly 32 remains covering the corresponding wiring terminal 322. The movable member 34 is disconnected from the protective cover 324 of at least one wiring assembly 32, so that the protective cover 324 of at least one wiring assembly 32 can be removed from the corresponding wiring terminal 322.

[0036] The movable part 34 is connected to the protective cover 324 of at least one wiring component 32, including: the movable part 34 and the protective cover 324 of at least one wiring component 32 are abutted and connected, the movable part 34 and the protective cover 324 of at least one wiring component 32 are clamped and connected, the movable part 34 and the protective cover 324 of at least one wiring component 32 are magnetically attracted, etc. The present application does not limit the connection method between the movable part 34 and the protective cover 324 of at least one wiring component 32, as long as the protective cover 324 of at least one wiring component 32 remains covering the corresponding wiring terminal 322 when the movable part 34 is connected to the protective cover 324 of at least one wiring component 32.

[0037] When the protective cover 324 of at least one wiring assembly 32 remains covering the corresponding wiring terminal 322, the wiring terminal 322 of at least one wiring assembly 32 is hidden in the base 10 and the corresponding protective cover 324. In this way, users (including operators, etc.) cannot touch the wiring terminal 322, reducing the risk of electric shock to the user and improving the safety protection of the wiring device 1 and electrical equipment.

[0038] The protective cover 324 of at least one wiring assembly 32 can be removed from the corresponding wiring terminal 322, so that the wiring terminal 322 of at least one wiring assembly 32 can be exposed. The exposed wiring terminal 322 facilitates user wiring or maintenance (such as replacement, inspection, and measurement).

[0039] Each terminal 322 in a wiring assembly 32 is equipped with a dedicated protective cover 324. For example, when a terminal 322 in a wiring assembly 32 needs to be wired, the protective cover 324 of that wiring assembly 32 is removed from the terminal 322, exposing the terminal 322. The protective covers 324 of the remaining wiring assemblies 32 can remain covering the corresponding terminal 322. Because the terminal 322 of the wiring assembly 32 that does not need wiring is covered by the protective cover 324, the user cannot access the terminal 322 hidden under the protective cover 324, reducing the possibility of electric shock to the user and further improving the safety of the wiring device 1 and the electrical equipment.

[0040] In addition, when the electrical equipment is used in a DC system with a voltage exceeding 1500V, the connection terminals 322 can be hidden under the protective cover 324, ensuring that the positive and negative connection terminals are not exposed at the same time, thereby reducing design costs.

[0041] More specifically, the base 10 is provided with a slide groove 12 for moving with the movable member 34 along a first direction (eg Figure 1 In this embodiment, the number of the chute 12 corresponds to the number of the wiring unit 30. The chute 12 and the wiring assembly 32 are connected along the second direction (as shown in the X direction). Figure 2(X direction shown in ).

[0042] In this embodiment, the protective cover 324 is rotatably connected to the base 10, that is, the protective cover 324 is a flip cover. Rotation of the protective cover 324 relative to the base 10 enables the protective cover 324 to be opened or closed relative to the base 10. In each wiring assembly 32, when the protective cover 324 is flipped open, the wiring terminals 322 are exposed outside the protective cover 324. In each wiring assembly 32, when the protective cover 324 is closed, the wiring terminals 322 are covered by the protective cover 324 and are hidden between the protective cover 324 and the base 10.

[0043] The movable member 34 includes a connecting portion 342 and a limiting portion 344. The connecting portion 342 is slidably connected to the chute 12 along a first direction. The limiting portion 344 can move relative to the base 10 along with the connecting portion 342. Movement of the movable member 344 relative to the base 10 allows the limiting portion 344 to engage with or disengage from the protective cover 324 of at least one wiring assembly 32. The connecting portion 342 is slidably connected to the chute 12, which guides the movement of the connecting portion 342 relative to the base 10, thereby improving the smoothness of the movement of the movable member 34 and facilitating user operation.

[0044] When the protective cover 324 of at least one wiring assembly 32 covers the corresponding wiring terminal 322, in the third direction, the at least one protective cover 324 is located between the restricting portion 344 and the base 10. The third direction is different from the first direction, which is also different from the second direction. The protective cover 324 of at least one wiring assembly 32 is located between the base 10 and the restricting portion 344. That is, the restricting portion 344 is located on the side of the protective cover 324 of the at least one wiring assembly 32 facing away from the base 10. The restricting portion 344 is used to block and restrict the movement of the protective cover 324 relative to the base 10. In this embodiment, the first direction, the second direction, and the third direction are orthogonal to each other.

[0045] When the restricting portion 344 is located on the side of the protective cover 324 of at least one wiring assembly 32 facing away from the base 10, the restricting portion 344 blocks and restricts the protective cover 324 of at least one wiring assembly 32 from rotating relative to the base 10, thereby ensuring that the protective cover 324 of at least one wiring assembly 32 remains covering the corresponding wiring terminal 322. Simply moving the restricting portion 344 to the side of the protective cover 324 of the wiring assembly 32 facing away from the base 10 can restrict the protective cover 324 of the wiring assembly 32 from remaining covering the corresponding wiring terminal 322, thereby facilitating user use.

[0046] In this embodiment, each wiring unit 30 has three wiring assemblies 32. These three wiring assemblies 32 include a first wiring assembly 301, a second wiring assembly 302, and a third wiring assembly 303, arranged sequentially along a first direction. For ease of description, the wiring terminal 322 of the first wiring assembly 301 is referred to as pole A, the wiring terminal 322 of the second wiring assembly 302 is referred to as pole B, and the wiring terminal 322 of the third wiring assembly 303 is referred to as pole C. It will be appreciated that each wiring unit 30 may have at least two wiring assemblies 32. The protective cover 324 of the second wiring assembly 302 is provided with a first measurement hole 3242 to allow access to a probe of a test instrument.

[0047] The restricting portion 344 includes a first restricting sub-portion 3442 and a second restricting sub-portion 3444. The first restricting sub-portion 3442 is connected to the connecting portion 342, and the second restricting sub-portion 3444 is connected to the connecting portion 342. The first restricting sub-portion 3442 and the second restricting sub-portion 3444 are used to maintain the protective covers 324 of two of the first wiring assembly 301, the second wiring assembly 302, and the third wiring assembly 303 over the corresponding wiring terminals 322. The position of the first restricting sub-portion 3442 and the second restricting sub-portion 3444 relative to the base 10 can be adjusted by sliding the connecting portion 342 along the slide groove 12.

[0048] The connecting portion 342 slides along the slide groove 12, changing the positions of the first limiting sub-portion 3442 and the second limiting sub-portion 3444 relative to the base 10. The slide groove 12 includes a first end wall 121 and a second end wall 122 disposed opposite each other along a first direction. In this embodiment, the spacing between the first limiting sub-portion 3442 and the second limiting sub-portion 3444 is such that, while the first limiting sub-portion 3442 and the second limiting sub-portion 3444 each retain the protective cover 324 of one wiring assembly 32 covering the corresponding wiring terminal 322, the protective cover 324 of the remaining wiring assembly 32 can be opened to expose the corresponding wiring terminal 322.

[0049] In this embodiment, there are three wiring units 30. For the convenience of description, the three wiring units 30 are respectively the first wiring unit 101, the second wiring unit 102 and the third wiring unit 103. According to the position of the connecting portion 342 in the chute 12, Figure 2 The first wiring unit 101, the second wiring unit 102 and the third wiring unit 103 shown in the figure are in different states respectively, wherein the first wiring unit 101 is in the first state, the second wiring unit 102 is in the second state, and the third wiring unit 103 is in the third state.

[0050] See also Figure 3aFirst wiring unit 101 is in the first state, with connection portion 342 of first wiring unit 101 in contact with first end wall 121. First limiting portion 3442 is located on protective cover 324 of first wiring assembly 301, and second limiting portion 3444 is located on protective cover 324 of second wiring assembly 302. Because protective cover 324 of first wiring assembly 301 is blocked (restricted or blocked) by first limiting portion 3442, protective cover 324 of first wiring assembly 301 cannot be opened, and terminal A is concealed between protective cover 324 of first wiring assembly 301 and base 10. Because protective cover 324 of second wiring assembly 302 is blocked (restricted or blocked) by second limiting portion 3444, protective cover 324 of second wiring assembly 302 cannot be opened, and terminal B is concealed between protective cover 324 of second wiring assembly 302 and base 10. Protective cover 324 of third wiring assembly 303 is not restricted or blocked by restricting portion 344. Protective cover 324 of third wiring assembly 303 can be flipped open, exposing terminal C. A user can open protective cover 324 of third wiring assembly 303 to expose terminal C. A test instrument probe can then be inserted through first measurement hole 3242 of protective cover 324 of second wiring assembly 302 to contact terminal B, thereby measuring the voltage between terminals B and C.

[0051] See also Figure 3b Second wiring unit 102 is in the second state, with connection portion 342 spaced apart from first end wall 121 and second end wall 122. First limiting sub-portion 3442 is located on protective cover 324 of first wiring assembly 301, and second limiting sub-portion 3444 is located on protective cover 324 of third wiring assembly 303. Because protective cover 324 of first wiring assembly 301 is blocked (restricted or blocked) by first limiting sub-portion 3442, protective cover 324 of first wiring assembly 301 cannot be opened, and electrode A is hidden between protective cover 324 of first wiring assembly 301 and base 10. Because protective cover 324 of third wiring assembly 303 is blocked (restricted or blocked) by second limiting sub-portion 3444, protective cover 324 of third wiring assembly 303 cannot be opened, and electrode C is hidden between protective cover 324 of third wiring assembly 303 and base 10. The protective cover 324 of the second wiring assembly 302 is not restricted or blocked by the restricting portion 344 , and the protective cover 324 of the second wiring assembly 302 can be opened, and the B pole can be exposed.

[0052] See also Figure 3cThird wiring unit 103 is in the third state. Connecting portion 342 of third wiring unit 103 is spaced apart from first end wall 121 and in contact with second end wall 122. First limiting portion 3442 is located on protective cover 324 of second wiring assembly 302, and second limiting portion 3444 is located on protective cover 324 of third wiring assembly 303. Because protective cover 324 of second wiring assembly 302 is blocked (restricted or blocked) by first limiting portion 3442, protective cover 324 of second wiring assembly 302 cannot be opened, and the B terminal is hidden between protective cover 324 of second wiring assembly 302 and base 10. Because protective cover 324 of third wiring assembly 303 is blocked (restricted or blocked) by second limiting portion 3444, protective cover 324 of third wiring assembly 303 cannot be opened, and the C terminal is hidden between protective cover 324 of third wiring assembly 303 and base 10. Protective cover 324 of first wiring assembly 301 is not restricted or blocked by restricting portion 344. Protective cover 324 of first wiring assembly 301 can be flipped open, exposing terminal A. A user can open protective cover 324 of first wiring assembly 301 to expose terminal A. A test instrument probe can then be inserted through first measurement hole 3242 of protective cover 324 of second wiring assembly 302 to contact terminal B, thereby measuring the voltage between terminals A and B.

[0053] In this embodiment, pole A is the DC positive pole, pole B is the neutral point, and pole C is the DC negative pole. That is, the positive pole, neutral point, and negative pole of the DC system are arranged at the corresponding positions of pole A, pole B, and pole C respectively. The voltage between the positive pole or negative pole and the neutral point can be measured, and there will be no situation where the measuring equipment is accidentally connected to the positive and negative poles, resulting in high voltage damaging the equipment, thereby improving the reliability of the wiring device 1 and the electrical equipment.

[0054] It is understood that the first wiring unit 101, the second wiring unit 102, and the third wiring unit 103 may also be in the same state. For example, the first wiring unit 101, the second wiring unit 102, and the third wiring unit 103 may all be in the first state. Two of the first wiring unit 101, the second wiring unit 102, and the third wiring unit 103 may be in the same state. For example, the first wiring unit 101 and the second wiring unit 102 may both be in the first state, and the third wiring unit 103 may be in the second state.

[0055] It is understood that the wiring unit 30 can switch between a first state, a second state, and a third state. The number of wiring units 30 on the wiring device 1 can be one, two, or more. When there are at least two wiring units 30, the states of at least two wiring units 30 can be partially the same or different.

[0056] In any one of the first, second and third states of the wiring unit 30 , only a single protective cover 324 can be opened, so that the wiring terminals 322 of the wiring assembly 32 with the opened protective cover 324 can be tested or maintained.

[0057] The wiring device 1 and electrical equipment provided in this embodiment can provide the protective functions of a conventional cover while reducing the risk of simultaneous exposure of terminals of different polarities. By providing a protective cover 324 for the terminal 322 and limiting the position of the movable member 34 in different positions, the terminal 322 of different polarities is prevented from being exposed simultaneously. By providing a first measuring hole 3242 on the protective cover 324 of the second wiring assembly 302, combined with the position of the connecting portion 342 of the movable member 34, the voltage between the terminal 322 of the second wiring assembly 302 and the terminals 322 on either side can be measured, while the terminals 322 on either side cannot be directly measured.

[0058] In other embodiments of the present application, pole A may be a first-phase AC pole, pole B may be a second-phase AC pole, and pole C may be a third-phase AC pole.

[0059] In other embodiments of the present application, the present application does not limit the connection method between the protective cover 324 and the base 10. For example, the protective cover 324 may not be a flip cover, but may be slidably connected to the base 10. The movable member 34 may be connected to the protective cover 324 by snapping, magnetic attraction, etc. When the movable member 34 is connected to the protective cover 324, the protective cover 324 remains covering the corresponding terminal 322.

[0060] In other embodiments of the present application, the present application does not limit the connection method between the movable member 34 and the base 10. For example, the movable member 34 and the base 10 can be rotatably connected.

[0061] See also Figure 4 and Figure 5 The structure of the wiring device 1 provided in the second embodiment of the present application is substantially the same as that of the wiring device 1 provided in the first embodiment of the present application, and the difference lies at least in the structure of the movable part 34 .

[0062] The movable member 34 includes a connecting portion 342 and a limiting portion 344. The connecting portion 342 is slidably connected to the slide groove. The limiting portion 344 can move relative to the base 10 along with the connecting portion 342.

[0063] The restricting portion 344 includes a first restricting sub-portion 3442, a second restricting sub-portion 3444, and a blocking piece 3446. The first restricting sub-portion 3442 is connected to the connecting portion 342, and the second restricting sub-portion 3444 is connected to the connecting portion 342. The first restricting sub-portion 3442 and the second restricting sub-portion 3444 are spaced apart. The first end of the blocking piece 3446 is rotatably connected to the first restricting sub-portion 3442, and the second end of the blocking piece 3446 can be connected to or disconnected from the second restricting sub-portion 3444.

[0064] The blocking piece 3446 is rotated relative to the first limiting sub-portion 3442 until the blocking piece 3446 is in a horizontal position along the first direction (eg Figure 2 ). The second end of the blocking piece 3446 is connected to the second limiting sub-portion 3444. The blocking piece 3446 keeps the protective covers 324 of all the wiring assemblies 32 covering the corresponding wiring terminals 322. That is, all the protective covers 324 cannot be opened because they are restricted and blocked.

[0065] In this embodiment, each protective cover 324 is provided with a first measurement hole 3242, and the baffle 3446 is provided with a plurality of second measurement holes 352. When the second end of the baffle 3446 is connected to the second limiting sub-portion 3444, by adjusting the position of the connecting portion 342 in the chute 12, each first measurement hole 3242 is aligned with a second measurement hole 352, allowing voltage measurement without opening the protective cover 324. It is understood that the number of second measurement holes 352 on the baffle 3446 can be one, and the second measurement hole 352 can be a single elongated hole.

[0066] Through the second measuring hole 352 of the protective cover 324 and the blocking piece 3446 , combined with the position of the movable member 34 , the purpose of performing voltage measurement without opening each protective cover 324 is achieved.

[0067] When the second end of the blocking piece 3446 is separated from the second limiting sub-portion 3444, the blocking piece 3446 is rotated relative to the first limiting sub-portion 3442 until the blocking piece 3446 is connected to the first limiting sub-portion 3442 along the second direction, that is, the blocking piece 3446 is in the Figure 5 The vertical state shown in .

[0068] When the blocking piece 3446 is in the vertical position, similar to the first embodiment, the wiring unit 30 has a first state, a second state, and a third state. In the first state, the first wiring unit 101 has the protective cover 324 of the first wiring assembly 301 blocked and restrained by the blocking piece 3446 and the first restraining sub-portion 3442, the protective cover 324 of the third wiring assembly 303 blocked and restrained by the second restraining sub-portion 3444, and the protective cover 324 of the second wiring assembly 302 can be flipped open. In the second state, the second wiring unit 102 has the protective cover 324 of the second wiring assembly 302 blocked and restrained by the blocking piece 3446 and the first restraining sub-portion 3442, the protective cover 324 of the third wiring assembly 303 blocked and restrained by the second restraining sub-portion 3444, and the protective cover 324 of the first wiring assembly 301 can be flipped open. The third wiring unit 103 is in the third state. The protective cover 324 of the first wiring assembly 301 is blocked and restricted by the blocking piece 3446 and the first limiting sub-portion 3442. The protective cover 324 of the second wiring assembly 302 is blocked and restricted by the second limiting sub-portion 3444. The protective cover 324 of the third wiring assembly 303 can be opened.

[0069] In any one of the first, second and third states of the wiring unit 30 , only a single protective cover 324 can be opened, so that the wiring terminals 322 of the wiring assembly 32 with the opened protective cover 324 can be tested or maintained.
