Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical appliances, and more specifically to a wiring device. Background Technology

[0002] When using existing terminal blocks in electrical equipment to make connections, the depth of insertion of the external conductor can only be judged by feeling or experience. This often leads to loose connections or unreliable connections between the terminal block and the external conductor. Summary of the Invention

[0003] The purpose of this invention is to overcome at least one defect of the prior art and provide a wiring device that ensures the reliability of the wiring between the external connection terminal and the external conductor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wiring device includes an external connection terminal and a wiring position indicator mechanism. The external connection terminal includes a terminal block with a wiring hole for inserting an external conductor along direction d3. The wiring position indicator mechanism includes an indicator engagement structure that engages with the external conductor and a second elastic reset member. The indicator engagement structure has a first position and a second position. When the external conductor is inserted into the wiring hole and reaches a preset position, the indicator engagement structure is driven by the external conductor to move from the first position to the second position. When the indicator engagement structure is in the second position, the wiring position indicator mechanism provides a position indication signal. The second elastic reset member acts on the indicator engagement structure to make it tend to move towards the first position.

[0006] Furthermore, the indicator is configured to move as a whole with the structure.

[0007] Furthermore, the indicating and cooperating structure is moved as a whole along direction d3.

[0008] Furthermore, the indicating mating structure includes a mating structure driven plate, which is used to drive the indicating mating structure to move from a first position to a second position by being pressed by an external conductor; in the direction d3, one end of the wiring hole is used for inserting an external conductor, and the mating structure driven plate is disposed on one side of the other end of the wiring hole.

[0009] Furthermore, the second elastic reset member is a compression spring, one end of which is fixedly installed and the other end is engaged with the driven plate of the mating structure; in the direction d3, the second elastic reset member and the terminal block are respectively located on both sides of the driven plate of the mating structure.

[0010] Furthermore, the wiring position indication mechanism also includes a position monitoring element. When the indicating mating structure moves to the second position, the position monitoring element is triggered by the moving plate of the mating structure to issue a position indication signal.

[0011] In the direction d3, the position monitoring element and the terminal block are located on both sides of the position monitoring element.

[0012] Furthermore, the positioning monitoring element is a micro switch.

[0013] Furthermore, the terminal block is fixedly installed, and the external connection terminal also includes a wiring screw, which is inserted radially into the wiring hole and threadedly connected to the terminal block;

[0014] The indicating mating structure includes a mating structure shielding part; when the indicating mating structure is in a first position, the mating structure shielding part shields the wiring screw; when the indicating mating structure is in a second position, the mating structure shielding part avoids the wiring screw.

[0015] Furthermore, the indicating mating structure also includes a driven part connected to the shielding part of the mating structure. The driven part mates with the second elastic reset member and is used for transmission mating with an external conductor.

[0016] Furthermore, the driven part includes a mating part, which is bent and connected to the shielding part of the mating structure; the second elastic reset member is a compression spring, one end of which is fixedly set and the other end of which mates with the mating part; in the direction d3, one end of the wiring hole is used for inserting an external conductor and the mating part is set on one side of the other end of the wiring hole, and the second elastic reset member and the wiring hole are respectively located on both sides of the mating part.

[0017] Furthermore, the terminal block is provided with a wiring hole, which is a third wiring hole; the indicating mating structure also includes a mating structure insertion part, which is used to drive the indicating mating structure to move from the first position to the second position by being pressed by an external conductor.

[0018] Furthermore, the wiring position indication mechanism also includes a position monitoring element, and the indication mating structure triggers the position monitoring element at the second position to make it emit a position indication signal.

[0019] Furthermore, the indicating mating structure also includes a mating structure triggering part connected to the mating part. The mating structure triggering part is used to trigger the position monitoring element when the indicating mating structure is in the second position. In the direction d3, the mating structure triggering part and the wiring hole are respectively located on both sides of the mating part of the indicating mating mechanism. The mating structure insertion part of the indicating mating structure is connected to the mating part, and the mating structure insertion part and the mating structure triggering part are respectively located on both sides of the mating part in the direction d3.

[0020] The wiring device of the present invention has a wiring position indicator mechanism that can accurately reflect whether the external conductor is inserted into the wiring hole in place, thereby avoiding the problem of unreliable connection and / or poor conductivity (lack of connection) between the external connection terminal and the external conductor due to the external conductor not being inserted in place.

Detailed Implementation

[0033] The following embodiments, in conjunction with the accompanying drawings, further illustrate specific implementations of the wiring device of the present invention. The wiring device of the present invention is not limited to the descriptions in the following embodiments.

[0034] The wiring device of this invention can be applied to various electrical devices, that is, the wiring device is part of the electrical device. The electrical device can be a plug-in base, circuit breaker, contactor, disconnector, etc. The plug-in base is an electrical device that at least supports an electricity meter and an outgoing switch and connects them to the corresponding electrical circuit. Figure 1-10 The diagram shows a first embodiment of the wiring device.

[0035] The wiring device of the first embodiment includes an external connection terminal and a wiring position indication mechanism. The external connection terminal includes a terminal block 731, which has a wiring hole for an external conductor 86 (i.e., an incoming or outgoing external conductor) to be inserted along direction d3. The wiring position indication mechanism includes an indicating engagement structure 773 and a second elastic reset member 762 that are in drive with the external conductor 86. The indicating engagement structure 773 has a first position and a second position. When the external conductor 86 is inserted into the wiring hole and reaches a preset position (i.e., the length of the external conductor 86 inserted into the wiring hole reaches a preset length, or the depth of the external conductor 86 inserted into the wiring hole reaches a predetermined depth), the indicating engagement structure 773 is driven by the external conductor 86 to move from the first position to the second position. That is, when the external conductor 86 is inserted into the wiring hole and reaches the preset position, the external conductor 86 drives the indicating engagement structure 773 to move from the first position to the second position. When the indicating engagement structure 773 is in the second position, the wiring position indication mechanism gives a position indication signal. The second elastic reset member 762 acts on the indicating engagement structure 773, causing it to tend to move towards the first position; that is, when the external conductor 86 is removed, the second elastic reset member 762 acts on the indicating engagement structure 773, causing it to move from the second position to the first position. The external conductor 86 is preferably a rigid wire, such as a copper rigid wire, an aluminum rigid wire, or other alloy rigid wire.

[0036] The wiring device has an in-place indicator mechanism that can accurately reflect whether the external conductor 86 is properly inserted into the wiring hole, thereby avoiding the problem of unreliable connection and / or poor conductivity (e.g., loose connection) between the external wiring terminal and the external conductor 86 due to improper insertion of the external conductor 86.

[0037] The arrival indication signal includes a photoelectric signal; such as... Figure 1-2 As shown in Figures 4 and 6, the wiring position indication mechanism also includes a position monitoring element 771, which emits a position indication signal when triggered by the indication and mating structure 773 that moves to the second position.

[0038] Specifically, the position monitoring element 771 is a micro switch. Furthermore, the position monitoring element 771 is connected to the sampling circuit board 955 of the sampling device.

[0039] As another embodiment of the position monitoring element 771, the position monitoring element 771 is a position detector (e.g., a photoelectric position sensor). When the position detector detects that the indicating mating structure 773 has moved to the second position, it indicates that the external conductor 86 has been inserted into place.

[0040] The positioning indication signal includes a marker display status change signal that can be directly observed by the operator. For example, a portion of the indicating mating structure 773 can always be observed by the operator when the external conductor 86 is not inserted into the wiring hole or is not fully inserted. When the external conductor 86 is fully inserted, the indicating mating structure 773 moves to the second position, and that portion of the indicating mating structure 773 becomes completely invisible. Alternatively, the indicating mating structure 773 has two indicator marks, corresponding to the first and second positions of the indicating mating structure 773, respectively. When the indicating mating structure 773 is in the first position, the first mark can be fully observed by the operator and the second mark is completely invisible to the operator. When the indicating mating structure 773 is in the second position, the second mark can be fully observed by the operator and the first mark is completely invisible to the operator.

[0041] like Figure 1-2 As shown in 6-10, the indicator and mating structure 773 is moved as a whole and switches between a first position and a second position by moving as a whole.

[0042] Specifically, the indicating and mating structure 773 is moved as a whole along direction d3, that is, the indicating and mating structure 773 is moved as a whole in a straight line along direction d3.

[0043] As another embodiment of the movement mode of the indicated mating structure 773, the indicated mating structure 773 is moved as a whole along a curve (e.g., an arc) or rotated.

[0044] like Figure 1-2 As shown in 6-10, the second elastic reset member 762 is a compression spring, one end of which is fixedly installed (for example, this end is fitted with the housing of the electrical device to which the wiring device belongs for fixed installation) and the other end is fitted with the indicating engagement structure 773.

[0045] As another embodiment of the second elastic reset member 762, the second elastic reset member 762 is a tension spring, a spring sheet, or a torsion spring, or other elastic members that meet the functional requirements. Those skilled in the art can replace them according to actual needs, and they will not be listed one by one here.

[0046] like Figure 1-6 The diagram shows a second embodiment of the wiring device, which differs from the wiring device in the following ways:

[0047] like Figure 1-6As shown, the external connection terminal also includes an operating component and a terminal block 74. The operating component includes a terminal block 731, which is movable along direction d2. The terminal block 74 is inserted into the terminal block 731 along direction d3 and is used to electrically connect with the internal circuit of the electrical device to which the wiring device belongs (the internal circuit of the electrical device refers to the circuit outside the wiring device that is electrically connected to the terminal block 74). A wiring hole is formed on each side of the terminal block 74. The two wiring holes are arranged side by side along direction d2 and are respectively the first wiring hole 791 and the second wiring hole 792. The terminal block 74 includes a first wiring layer 741 and a second wiring layer 742 that are stacked together along direction d2 and are made of different materials. The first wiring layer 741 is disposed facing the first wiring hole 791 and the second wiring layer 742 is disposed facing the second wiring hole 792. The first wiring layer 741 cooperates with the operating component to press the external conductor 86 inserted into the first wiring hole 791, and the second wiring layer 742 cooperates with the operating component to press the external conductor 86 inserted into the second wiring hole 792.

[0048] The structural design of the external connection terminal and the terminal block 74 allows the external connection terminal to be connected to external conductors 86 of different materials, thereby broadening the application scenarios of the wiring device. When the wiring device is applied to electrical devices, it also improves the compatibility of the electrical devices.

[0049] Specifically, the terminal block 731 has a square frame structure, including a front wall and a rear wall of the terminal block arranged opposite each other along direction d2, and two side walls of the terminal block arranged opposite each other along direction d1. The front wall of the terminal block is opposite to the first wiring layer 741, and the bottom wall of the terminal block is opposite to the second wiring layer 742. The front wall, the two side walls, and the first wiring layer 741 cooperate to form a first wiring hole 791, and the rear wall, the two side walls, and the second wiring layer 742 cooperate to form a second wiring hole 792. Further, the terminal block 731 is a copper wiring frame, an aluminum alloy wiring frame, or an aluminum wiring frame, etc.

[0050] Specifically, the first wiring layer 741 is a copper wiring layer, and the second wiring layer 742 is an aluminum wiring layer. That is, the external connection terminal can be used to connect to either the copper external conductor 86 or the aluminum external conductor 86. Furthermore, the first wiring layer 741 and the second wiring layer 742 are laminated together in parallel.

[0051] like Figure 3-6As shown, the wiring device of the second embodiment further includes a first elastic reset member 761; the terminal block 731 has two wiring positions, namely a first wiring position and a second wiring position; the terminal block 731 switches between the two wiring positions by moving along direction d2; the first elastic reset member 761 acts on the terminal block 731 to keep it in the first wiring position. When the terminal block 731 is in the first wiring position, the diameter of the first wiring hole 791 is larger than the diameter of the second wiring hole 792, thereby allowing the external conductor 86 to be smoothly inserted into the first wiring hole 791. At this time, the first elastic reset member 761 is in a released state; in actual use, when the terminal block 731 is in the first wiring position, the diameter of the first wiring hole 791 is much larger than the diameter of the second wiring hole 792, and the diameter of the second wiring hole 792 becomes too small to be used for wiring. When the terminal block 731 is in the second wiring position, the diameter of the first wiring hole 791 is smaller than the diameter of the second wiring hole 792, thereby allowing the external wire 86 to be smoothly inserted into the second wiring hole 792. At this time, the first elastic reset member 761 is in an energy storage state. In actual use, when the terminal block 731 is in the second wiring position, the diameter of the second wiring hole 792 is much larger than the diameter of the first wiring hole 791, and the diameter of the first wiring hole 791 becomes too small to be used for wiring.

[0052] Specifically, the first elastic reset member 761 is a compression spring. When the terminal block 731 moves from the first wiring position to the second wiring position, it compresses the first elastic reset member 761 to store energy. Furthermore, one end of the first elastic reset member 761 cooperates with the terminal block 731, and the other end cooperates with the wiring device housing 81 of the wiring device.

[0053] As another embodiment of the first elastic reset member 761, the first elastic reset member 761 is a tension spring, a serpentine spring sheet, or a torsion spring, or other elastic components that meet the functional requirements. Those skilled in the art can replace them according to actual needs, and they will not be listed one by one here.

[0054] like Figure 1-2 As shown in Figures 4 and 6, the operating assembly further includes a wiring screw, which is threadedly connected to the terminal block 731. One end of the wiring screw is inserted into the first wiring hole 791 and is used to cooperate with the terminal block 731 and the terminal plate 74 to press the external conductor 86 inserted into the first wiring hole 791 or the external conductor inserted into the second wiring hole 792. Further, the external connection terminal also includes a pressure plate 753, which is inserted into the first wiring hole 791 and opposite to the terminal plate 74. The wiring screw is rotatably connected to the pressure plate 753, and when the wiring screw is tightened by external force, the wiring screw and the pressure plate 753 rotate relative to each other.

[0055] Specifically, the external connection terminal includes two terminal screws, namely a first terminal screw 71 and a second terminal screw 72, both of which are rotatably connected to the pressure plate 753. They are arranged side-by-side and spaced apart along direction d3 (i.e., the extension direction of the first terminal hole 791 and the second terminal hole 792). The first terminal screw 71 and the second terminal screw 72 work together to clamp the external conductor 86, further improving the reliability of the connection between the external conductor 86 and the external connection terminal. Furthermore, the wiring device housing 81 of the wiring device also has a first operating hole 831 and a second operating hole 832, with the operating ends of the first terminal screw 71 and the second terminal screw 72 slidably disposed within the first operating hole 831 and the second operating hole 832, respectively.

[0056] like Figure 1-4 As shown in Figure 6, the wiring device of the second embodiment further includes a wiring device housing 81 for accommodating external connection terminals. The wiring device housing 81 includes a first opening 821 that mates with the first wiring hole 791 and a second opening 822 that mates with the second wiring hole 792. The first opening 821 is used for the corresponding external conductor 86 to pass through and be inserted into the first wiring hole 791, and the second opening 822 is used for the corresponding external conductor 86 to pass through and be inserted into the second wiring hole 792.

[0057] Specifically, the wiring device housing 81 is served by the housing of the electrical device to which the wiring device belongs, or by a structure that is independent of the housing of the electrical device and fixedly fitted thereto. The wiring device housing 81 has a terminal cavity 84, and the external connection terminal is located within the terminal cavity 84. The first elastic reset member 761 acts on the terminal block 731, causing it to engage with the side wall of the terminal cavity 84 to hold the terminal block 731 in the first wiring position. At this time, the first elastic reset member 761 is in a released state. The operator uses a tool (e.g., a screwdriver) to press the wiring screw, driving the terminal block 731 to overcome the force of the first elastic reset member 761 and move it from the first wiring position to the second wiring position, thus switching the first elastic reset member 761 to an energy storage state. Figure 1-6As shown, the wiring device in the second embodiment further includes a first baffle 751 and a second baffle 752; when the terminal block 731 switches between a first wiring position and a second wiring position, the first baffle 751 and the second baffle 752 move synchronously with the terminal block 731; when the terminal block 731 is in the first wiring position, the first baffle 751 avoids the first opening 821, allowing the external conductor 86 to pass through the first opening 821 and be inserted into the first wiring hole 791, while the second baffle 752 blocks the second opening 822, preventing the external conductor 86 from passing through. The second opening 922 allows insertion into the second wiring hole 792 and prevents the operator from accidentally touching the terminal block 731 through the second opening 822. When the terminal block 731 is in the second wiring position, the second baffle 752 avoids the second opening 822, allowing the external conductor 86 to pass through the second opening 822 and be inserted into the second wiring hole 792. The first baffle 751 blocks the first opening 821, preventing the external conductor 86 from passing through the first opening 821 and being inserted into the first wiring hole 791, and also preventing the operator from accidentally touching the terminal block 731 through the first opening 821. When the terminal block 731 is in a certain wiring position, only the corresponding wiring hole is open to allow the external conductor 86 to be inserted, thereby preventing the operator from making incorrect wiring. Furthermore, the wiring device of the second embodiment also includes a first indicating structure. The first indicating structure includes two sets of indicating marks respectively disposed on the first baffle 751 and the second baffle 752. The two sets of indicating marks are used to indicate the material of the wiring layer corresponding to the wiring hole into which the external conductor 86 can be inserted (that is, the wiring hole corresponding to the opening of the unobstructed wiring device housing 81), further prompting the operator to avoid the operator inserting the copper external conductor 86 into the second wiring hole 791 or inserting the aluminum external conductor 86 into the first wiring hole 791.

[0058] Specifically, the first baffle 751 is fixedly connected to the wire clamping plate 753; the second baffle 752 is fixedly connected to the terminal block 731. Of course, the first baffle 751 can also be configured to be fixedly connected to the terminal block 731, which is easily achievable by those skilled in the art using conventional techniques; alternatively, the second baffle 752 includes a second baffle mating part, which abuts against the terminal block 731 under the action of the first elastic reset member 761, so that the second baffle 752 and the terminal block 731 move synchronously. Furthermore, both the first baffle 751 and the second baffle 752 are insulating baffles.

[0059] like Figure 3 , 5As shown, the wiring device of the second embodiment further includes a second indicator structure. The second indicator structure includes a first indicator part 851 and a second indicator part 852 disposed on the wiring device housing 81. The first indicator part 851 and the second indicator part 852 are respectively disposed corresponding to the first opening 821 and the second opening 822, and are used to indicate the material of the wiring layer (that is, the wiring layer corresponding to the first wiring hole 791 and the second wiring hole 792) corresponding to the first opening 821 and the second opening 822.

[0060] Specifically, the first indicator 851 and the second indicator 852 are both protruding along direction d3 (i.e., the direction in which the external conductor 86 is inserted into the first wiring hole 791 and the second wiring hole 792). The first indicator 851 is closer to the side of the wiring device facing the operator than the second indicator 852. The length of the protrusion of the first indicator hole 851 is less than the length of the protrusion of the second indicator hole 852. The first opening 821, the first indicator 851, the second opening 822, and the second indicator 852 are arranged sequentially along direction d2 (i.e., the sliding direction of the terminal block 731). The first indicator 851 is located between the first opening 821 and the second opening 822. The first indicator 851 and the second indicator 852 are located on both sides of the second opening 822. The side of the first indicator 851 and the second indicator 852 facing the operator is provided with indicator marks. The two sets of indicator marks are used to indicate the material of the wiring layer corresponding to the first opening 821 and the second opening 822, respectively.

[0061] In another embodiment of the arrangement of the first indicator 851 and the second indicator 852, in the direction d1, the first indicator 851 is disposed on one side of the first opening 821, and the second indicator 852 is disposed on one side of the second opening 822. The first indicator 851 and the second indicator 852 are preferably located on the same side of the first opening 821 and the second opening 822.

[0062] It should be noted that in the wiring device of the first embodiment, the first indicator structure and the second indicator structure can be provided simultaneously, or one of them can be provided—that is, only the first indicator structure is provided without the second indicator structure, or only the second indicator structure is provided without the first indicator structure.

[0063] like Figure 1-2As shown in Figures 4 and 6, in the wiring device of the second embodiment, the indicating engagement structure 773 includes an engagement structure driven plate 772 for engaging with an external conductor 86. The engagement structure driven plate 772 is driven by the external conductor 86 to move the indicating engagement structure 773 from a first position to a second position. In the direction d3, one end of the wiring hole allows the external conductor 86 to be inserted, and the engagement structure driven plate 772 is disposed on one side of the other end of the wiring hole. Further, the engagement structure driven plate 772 includes a driven plate clearance hole 780 for a wiring plate 74 to pass through, and one end of the wiring plate 74 passes through the driven plate clearance hole 780 to be electrically connected to the internal circuit of the electrical device to which the wiring device belongs. Furthermore, the second elastic reset member 762 acts on the mating structure driven plate 772, causing the indicating mating structure 773 to tend to move towards the first position; that is, when the wiring device is in its initial state—when the external conductor 86 is not inserted into the wiring hole of the external connection terminal and when the external conductor 86 is inserted into the wiring hole of the external connection terminal but not in contact with the mating structure driven plate 772, the second elastic reset member 762 acts on the mating structure driven plate 772 to keep the indicating mating structure 773 in the first position; when the external conductor 86 is inserted into the wiring hole of the external connection terminal and is inserted in place, the external conductor 86 presses against the mating structure driven plate 772 to move the indicating mating structure 773 to the second position; after the external conductor 86 is removed, the force applied by the second elastic reset member 762 to the mating structure driven plate 772 causes the indicating mating structure 773 to move to the first position.

[0064] Specifically, when the indicating mating structure 773 is in the first position, the second elastic reset member 762 causes the mating structure driven plate 772 to abut against the terminal block 731, thereby keeping the indicating mating structure 773 in the first position.

[0065] Specifically, the second elastic reset member 762 is a compression spring, one end of which engages with the driven plate 772 of the mating structure, and the other end engages with the wiring device housing 81. Further, one end of the driven plate 772 engages with the second elastic reset member 762, and the other end engages with the position monitoring element 771. Further, the second elastic reset member 762 and the position monitoring element 771 are located on opposite sides of the wiring plate 74 in direction d2 and on the same side of the driven plate 772 in direction d3. Further, the wiring device also includes a guide structure for defining the movement trajectory of the driven plate 772 of the mating structure. The guide structure can be implemented using existing technology and will not be described in detail here.

[0066] It should be noted that the wiring device of the second embodiment can be used without a wiring position indicator mechanism.

[0067] like Figure 7-10The diagram shows a third embodiment of the wiring device, which differs from the wiring device of the first embodiment in that:

[0068] like Figure 7-10 As shown, the wiring device of the third embodiment also includes an external connection terminal, which includes a terminal block 731 and a connection screw. The terminal block 731 is provided with a third connection hole 794 extending in the direction d3. There is one third connection hole 794, that is, the external conductor 86 is inserted into the terminal block 731 in the direction d3. The connection screw is threaded to the terminal block 731 and one end is inserted into the third connection hole 794.

[0069] Specifically, the terminal block 731 is made of aluminum alloy.

[0070] Specifically, the wiring device of the third embodiment includes two wiring screws in its external connection terminal, namely a first wiring screw 71 and a second wiring screw 72, which are arranged side by side and spaced apart along direction d3. Both the first wiring screw 71 and the second wiring screw 72 are used to press the external conductor 86 tightly, further improving the reliability of the connection between the external conductor 86 and the terminal block 731.

[0071] like Figure 7-10 As shown, in the wiring device of the third embodiment, the indicating engagement structure 773 of the wiring position indicating mechanism includes an engagement structure blocking part 774. When the indicating engagement structure 773 is in the first position, the engagement structure blocking part 774 blocks the wiring screw (partially or completely blocking it), preventing the operator from operating the wiring screw. When the indicating engagement structure 773 is driven from the first position to the second position by the external conductor 86 inserted into the third wiring hole 794 and in place, the engagement structure blocking part 774 avoids the wiring screw, allowing the operator to operate the wiring screw to engage with the wiring socket 731 to press the external conductor 86 tightly. The engagement structure blocking part 774 can prevent the operator from operating the wiring screw before the external conductor 86 is fully inserted, and can also visually indicate whether the external conductor 86 is fully inserted. Further, the indicating engagement structure 773 includes a driven part 778 connected to the engagement structure blocking part 774. The driven part 778 engages with the second elastic reset member 762 and is used for transmission engagement with the external conductor 86. Furthermore, the driven part 778 includes a mating structure insertion part 779, one end of which is inserted into the third wiring hole 794, and is used to drive the indicating mating mechanism 773 to move from the first position to the second position by being pressed by the external conductor 86.

[0072] Specifically, when the indicating mating structure 773 is in the first position, both wiring screws are completely blocked by the mating structure blocking part 774; when the indicating mating structure 773 is in the second position, both wiring screws are avoided by the mating structure blocking part 774, allowing them to be operated by the operator.

[0073] Specifically, the activated part 778 further includes a mating part 775, which is bent and connected to the mating structure shielding part 774 and mates with the second elastic reset member 762. In the direction d3, one end of the third wiring hole 794 allows an external conductor 86 to be inserted therein, and the mating part 775 is located on one side of the other end of the third wiring hole 794. One end of the mating structure insertion part 779 is connected to the mating part 775, and the other end is inserted into the third wiring hole 794. The mating structure insertion part 779 and the mating structure shielding part 774 are spaced apart and both are located on one side of the mating part 775 in the direction d3. The second elastic reset member 762 is located on the other side of the mating part 775 in the direction d3. The mating part 775 has a mating hole 776 through which the wiring part 795 of the connector passes. The mating structure shielding part 774, the mating part 775, and the mating structure insertion part 779 are preferably an integral structure, forming a U-shape. One end of the mating part 775 is bent and connected to the mating structure shielding part 774 and mates with the second elastic reset member 762, and the other end is bent and connected to the mating structure insertion part 779.

[0074] Specifically, the terminal block 731 includes a terminal block body 793 and a terminal block wiring portion 795. The terminal block body 793 and the terminal block wiring portion 795 are preferably an integral structure. The terminal block body 793 is provided with a third wiring hole 794 in the middle. The terminal block wiring portion 795 is used to electrically connect to the internal circuit of the electrical device to which the wiring device belongs (in the second embodiment of the wiring device, when the external connection terminal is used as an external connection inlet terminal 70, the terminal block wiring portion 795 is electrically connected to the first copper busbar 110; when it is used as an external connection outlet terminal 80, the terminal block wiring portion 795 is electrically connected to the fourth copper busbar 140).

[0075] Specifically, the third wiring hole 794 is a circular hole, and the mating structure insertion part 779 is a cylinder.

[0076] like Figure 7-10As shown, the indicating mating structure 773 further includes a mating structure triggering part 777 connected to the mating part 775. The mating structure triggering part 777 is used to trigger the positioning monitoring element 771 when the indicating mating structure 773 is in the second position. Furthermore, both the mating structure triggering part 777 and the mating structure insertion part 779 are connected to one end of the mating part 775 in direction d3, and are located on both sides of the mating part 775 in direction d3. Furthermore, the mating structure triggering part 777 and the mating part 775 are an integral structure.

[0077] It should be noted that in the wiring device of the third embodiment, the mating structure blocking part 774, the mating structure triggering part 777, and the positioning monitoring element 771 can be provided simultaneously; or, only the mating structure blocking part 774 can be provided, without the mating structure triggering part 777 and the positioning monitoring element 771; or, only the mating structure triggering part 777 and the positioning monitoring element 771 can be provided, without the mating structure blocking part 774, and the mating structure insertion part 779 can also be omitted. Preferably, the wiring device of the third embodiment only provides the mating structure blocking part 774 and does not provide the mating structure triggering part 777 and the positioning monitoring element 771.

[0078] In another embodiment, in the wiring device of the third embodiment, the indicating mating structure 773 is rotatably configured. During the process of inserting the external conductor 86 into the third wiring hole 794 until it is fully inserted, the external conductor 86 presses against the driven part 778, causing the indicating mating mechanism 773 to rotate, thereby driving the mating structure blocking part 774 to rotate and avoid the wiring screw. Further, one end of the driven part 778 is rotatably configured and the other end is opposite to the third wiring hole 794. The external conductor 86 presses against the end of the driven part 778 opposite to the third wiring hole 794 to drive the indicating mating structure 773 to rotate.

[0079] The following is a fourth embodiment of the wiring device. The wiring device of the fourth embodiment adopts the wiring position indication mechanism of the wiring device of the second embodiment and the external connection terminal of the wiring device of the third embodiment. That is, the position monitoring element 771, the mating structure driven plate 772, and the terminal block body 793 are arranged sequentially along the direction d3. One end of the third wiring hole 794 is for the insertion of the external conductor 86. The mating structure driven plate 772 is arranged on one side of the third wiring hole 794 and is limited to the terminal block body 793. The wiring part 795 of the terminal block passes through the driven plate clearance hole 780 of the mating structure driven plate 772 and is electrically connected to the internal circuit of the electrical device.

[0080] The following is the fifth embodiment of the wiring device, which differs from the wiring device of the third embodiment in that the indicating mating structure 773 does not have a mating structure shielding part 774.
