Description

Technical Field

[0001] This invention relates to the field of power work tools, and in particular to a secondary anti-misconnection wiring tool. Background Technology

[0002] During the comprehensive automation upgrade of a substation, it is necessary to replace the corresponding secondary equipment and secondary cables. Since it is an operating station, it is not possible to carry out a complete shutdown upgrade. During the rotational shutdown process, the disconnection and connection process needs to be precisely controlled. In particular, the secondary cables of the operating equipment must not be accidentally disconnected, which could lead to power loss of the equipment and cause significant impact.

[0003] Currently, the main secondary safety measure for disconnecting and reconnecting wires is to seal the terminal blocks in non-working areas with insulating tape to effectively separate the terminals to be disconnected from the non-working terminals. However, due to varying skill levels, the sealing effect sometimes fails to meet requirements. In particular, the insulating tape is prone to peeling off during use, and situations where construction workers mistakenly identify working terminals and accidentally disconnect the wires occur frequently.

[0004] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Summary of the Invention

[0005] This invention discloses a secondary anti-misconnection wiring tool to solve the technical problem in the prior art where operators often accidentally disconnect wires when replacing corresponding secondary equipment and secondary cables.

[0006] This invention provides a secondary anti-misconnection wiring tool, including a partition plate for sealing and covering terminal blocks. A clamping member is provided on a first surface of the partition plate for fixing the partition plate to the terminal block. A working window corresponding to the terminal block is provided on a second surface of the partition plate. Multiple terminal cover plates corresponding to multiple terminals on the terminal block are provided on the working window. The terminal cover plates are hinged to the partition plate.

[0007] Optionally, the opposite sides of the partition plate are inclined upwards to form an inclined portion.

[0008] Optionally, the partition plate is further equipped with a plurality of cable clamping assemblies, and one of the cable clamping assemblies is provided at each of the opposite ends of the terminal cover plate;

[0009] The cable clamping assembly includes a support part and a clamping part. The clamping part is located on the side of the support part away from the terminal cover plate. The support part has a placement hole for placing the end of the cable. The clamping part is used to clamp and fix the cable.

[0010] Optionally, the clamping part is an elastic clamping part.

[0011] Optionally, a control circuit board is provided on the terminal cover, a first indicator light is provided on the side of the terminal cover facing the work window, and a second indicator light is provided on the side of the terminal cover away from the work window. Both the first indicator light and the second indicator light are electrically connected to the control circuit board.

[0012] A first magnetic sensor and a second magnetic sensor are respectively installed at opposite ends of the terminal cover. Both the first magnetic sensor and the second magnetic sensor are electrically connected to the control circuit board. Magnetic components are installed on the support.

[0013] When the terminal cover rotates relative to the partition plate to open the work window portion, the first magnetic sensor senses the magnetic element of one of the supports, and the first indicator light illuminates.

[0014] When the terminal cover rotates relative to the partition plate to close the work window portion, the second magnetic sensor senses the magnetic element of another support portion, and the second indicator light illuminates.

[0015] Optionally, the first indicator light and the second indicator light have different light colors.

[0016] Optionally, an instruction sign may also be provided on the side of the terminal cover facing the work window.

[0017] Optionally, the clamping element is a spring gripper.

[0018] Optionally, a whiteboard for marking is also provided on the partition.

[0019] Optionally, there are two whiteboards, which are located on opposite sides of the work window.

[0020] As can be seen from the above technical solutions, the embodiments of the present invention have the following advantages:

[0021] In this embodiment, the partition plate is fixed to the terminal block by a clamp to seal and cover the terminal block. When the operator disconnects the wire, the operator flips open the terminal cover plate on the corresponding terminal, while the terminal cover plates corresponding to the other terminals that do not need to be disconnected are closed. Through the above design, it is possible to effectively distinguish between the terminals to be disconnected and the terminals that do not need to be disconnected, and effectively prevent the accidental disconnection or connection during operation.

Detailed Implementation

[0028] This invention discloses a secondary anti-misconnection wiring tool to solve the technical problem in the prior art where operators often accidentally disconnect wires when replacing corresponding secondary equipment and secondary cables.

[0029] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 4The present invention provides a secondary anti-misconnection wiring tool, including a partition plate 1 for sealing and covering a terminal block. A clamping member 3 for fixing the partition plate 1 to the terminal block is provided on a first surface of the partition plate 1. A working window corresponding to the terminal block is provided on a second surface of the partition plate 1. A plurality of terminal cover plates 2 corresponding one-to-one with a plurality of terminals on the terminal block are provided on the working window. The terminal cover plates 2 are hinged to the partition plate 1.

[0031] It should be noted that the partition plate 13 in this embodiment is the core frame of the secondary professional anti-misoperation wiring tool. It is made of insulating material and is fixed to the terminal block to be disconnected via the clamping member 3 connected to it. In addition, the partition plate 1 specifically seals and covers the screw holes of the terminal block for disconnection.

[0032] In this embodiment, the partition plate 1 is fixed to the terminal block by the clamping member 3 to seal and cover the terminal block. When the operator disconnects the wire, the operator flips open the terminal cover plate 2 on the corresponding terminal. The terminal cover plate 2 corresponding to the other terminals that do not need to be disconnected is in the closed state. Through the above design, it is possible to effectively distinguish the terminals to be disconnected from the terminals that do not need to be disconnected, and effectively prevent the accidental disconnection or connection during operation.

[0033] Furthermore, in this embodiment, the opposite two sides of the partition plate 1 are inclined upward to form inclined portions 101.

[0034] It should be noted that the two opposite sides of the partition plate 1 mentioned above specifically refer to the two opposite length sides of the partition plate 1 that are parallel to the length direction of the terminal block. The two opposite length sides are inclined upward to form an inclined part 101, which avoids the partition plate 1 from obscuring the terminal number on the terminal block and makes it easier for the operator to observe the terminal number on the terminal block.

[0035] Furthermore, in this embodiment, a plurality of cable clamping assemblies are also installed on the partition plate 1, and one of the cable clamping assemblies is provided at each of the opposite ends of the terminal cover plate 2;

[0036] The cable clamping assembly includes a support part 4 and a clamping part 5. The clamping part 5 is located on the side of the support part 4 away from the terminal cover plate 2. The support part 4 has a placement hole for placing the end of the cable. The clamping part 5 is used to clamp and fix the cable.

[0037] It should be noted that after the operator completes the disconnection of the terminal, the operator places the end of the disconnected cable (specifically, the cable head end) into the aforementioned placement hole, and then clamps and secures the cable using the clamping part 5. Through this design, the disconnected cable can be secured using the cable clamping assembly, avoiding the risk of accidental contact with exposed metal.

[0038] Furthermore, in this embodiment, the clamping part 5 is an elastic clamping part.

[0039] It should be noted that the above design allows the clamping part 5 to adapt to cables of different diameters.

[0040] Furthermore, in this embodiment, a control circuit board is provided on the terminal cover plate 2. A first indicator light 7 is provided on the side of the terminal cover plate 2 facing the work window, and a second indicator light 8 is provided on the side of the terminal cover plate 2 away from the work window. Both the first indicator light 7 and the second indicator light 8 are electrically connected to the control circuit board.

[0041] A first magnetic sensor 10 and a second magnetic sensor are respectively installed at opposite ends of the terminal cover plate 2. Both the first magnetic sensor 10 and the second magnetic sensor are electrically connected to the control circuit board. A magnetic component 11 is installed on the support part 4.

[0042] It should be noted that when the terminal cover 2 rotates relative to the partition plate 1 to open the working window for the operator to disconnect the wires, the first magnetic sensor 10 senses the magnetic element 11 of one of the support parts 4, and the first indicator light 7 illuminates; when the terminal cover 2 rotates relative to the partition plate 1 to close the working window, the second magnetic sensor senses the magnetic element 11 of the other support part 4, and the second indicator light 8 illuminates. Through this design, the operator can better avoid accidental disconnection or reconnection by following the illumination of the first indicator light 7 and the second indicator light 8.

[0043] In addition, the first magnetic sensor 10 and the second magnetic sensor in this embodiment are specifically Hall sensors.

[0044] Furthermore, in this embodiment, the first indicator light 7 and the second indicator light 8 have different light colors.

[0045] It should be noted that in this embodiment, when the first indicator light 7 is lit, the operator can perform the disconnection and reconnection operations. Preferably, the light color of the first indicator light 7 is green. When the second indicator light 8 is lit, it indicates that the terminal cover 2 has closed the working window. At this time, no operation is required on the terminal corresponding to the terminal cover 2. Preferably, the light color of the second indicator light 8 is red.

[0046] Furthermore, in this embodiment, the terminal cover 2 is also provided with an instruction sign 6 on the side facing the work window.

[0047] It should be noted that, through the above design, when the terminal cover 2 is in the open state, the operator can observe the indicator label 6. The indicator label 6 is used to remind the operator to disconnect or reconnect wires at this terminal, avoiding accidental disconnection or reconnection. Specifically, the indicator label 6 is "Working here".

[0048] Furthermore, in this embodiment, the clamping member 3 is a spring clamp.

[0049] It should be noted that the spring clamps in this embodiment are made of insulating material. The spring clamps can accommodate terminal blocks of different widths. Specifically, the spring clamps are fixed to the partition plate 1 by fixing bolts. In this embodiment, the spring clamps clamp the label strip of the terminal block, thereby fixing the secondary anti-misconnection wiring tool to the label strip of the terminal block.

[0050] Furthermore, a whiteboard 9 is also provided on the partition plate 1.

[0051] There are two whiteboards 9, and the two whiteboards 9 are located on opposite sides of the work window.

[0052] It should be noted that when operators are working, after fixing the partition plate 1 to the terminal block, they can use an oil-based pen to mark the first and last terminals of the terminal block on the marking whiteboard 9 to prevent accidental contact. The markings can be wiped off after the work is completed, without affecting secondary use.

[0053] Furthermore, the "opposite sides" of the aforementioned work window specifically refer to the opposite sides parallel to the width direction of the terminal end. In this embodiment, the terminals on the terminal block are arranged in a straight line along the length direction of the terminal block.

[0054] The above is a detailed description of the specific structure of the secondary anti-misconnection wiring tool in this embodiment. The following will further describe the secondary anti-misconnection wiring tool in this embodiment through a specific usage process.

[0055] The specific usage process of the secondary anti-misconnection wiring tool in this embodiment is as follows:

[0056] After identifying the terminal block by the label strip, the staff prepares to disconnect the cable. The secondary anti-misconnection cable tool is clamped onto the terminal block with spring clips and aligned. When disconnecting the cable, the terminal cover 2 on the corresponding terminal is opened. The terminal cover 2 has a clear indication label 6, as well as a first indicator light 7 and a second indicator light 8, providing double protection and constantly reminding the staff to avoid accidental disconnection or connection during work. After the secondary cable is disconnected, the accidental contact measures (i.e., cable clamping components) set on both sides of the tool are used to fix the disconnected secondary cable to avoid the risk of accidental contact with exposed metal.

[0057] The above provides a detailed description of a secondary anti-misconnection wiring tool provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
