Description
Technical Field
[0001] This utility model relates to the field of electrical equipment technology, and in particular to an anti-misoperation insulating plug. Background Technology
[0002] During the maintenance and testing of relay protection and automatic safety devices, the connecting tabs of the disconnection test terminals in the current and voltage circuits need to be moved to the disconnected position. After the test, the connecting tabs need to be restored and moved to the connected position. However, in actual work, it is common for the connecting tabs to be missed or not properly connected during restoration. If this occurs in the current circuit, it will cause an open circuit, leading to a series of problems such as malfunction of the relay protection device and arc burn-out of the current circuit terminals. If it occurs in the voltage circuit, it will cause abnormal fluctuations in the voltage sampling of the relay protection and automatic safety devices.
[0003] In summary, existing technologies cannot ensure that the disconnection test terminals in the voltage and current circuits are properly connected after device maintenance and testing, and that there are no issues of missing or loose connections. Utility Model Content

[0033] Please see Figure 1 This utility model provides an anti-misoperation insulating plug 100, including an insulating plug body 1, an insulating isolation plate 2, a mounting rod 3, and a warning sign 4; the insulating plug body 1 includes an installation end and a connecting end arranged opposite to each other, for extending into the break gap of the terminal connecting piece; the insulating isolation plate 2 is disposed at the connecting end to prevent air breakdown; one end of the mounting rod 3 is disposed on the insulating isolation plate 2; the warning sign 4 is detachably installed at the other end of the mounting rod to indicate the installation status of the anti-misoperation insulating plug.
[0034] This utility model provides an anti-misoperation insulating plug 100. When implementing relay protection safety measures, the user inserts the insulating plug body 1 of the anti-misoperation insulating plug 100 one by one into the gaps of the broken terminal connecting pieces, and sets the warning sign 4 on the mounting rod 3. To prevent missing plugs, during the implementation of relay protection safety measures, an anti-misoperation insulating plug 100 should be inserted immediately after each connecting piece is cut open. When restoring the relay protection safety measures, the person implementing the measures pulls out the anti-misoperation insulating plug 100 and connects the broken test terminal connecting pieces. When implementing relay protection measures, the connection status of the broken test terminal blocks can be clearly distinguished among the numerous terminal blocks by directly observing the warning sign 4 of the anti-misoperation insulating plug 100, effectively preventing the occurrence of missing connections and loose connections.
[0035] It should be noted that the mounting rod 3 and the warning sign 4 are detachably connected in various ways, such as using interlocking buckles, as long as the detachable connection between the mounting rod 3 and the warning sign 4 can be achieved.
[0036] Specifically, in this embodiment, a detachable connection structure is provided between the other end of the mounting rod 3 and the opposite end face of the warning sign 4. The detachable connection structure includes a magnetic suction part 51 and a mating part 52 that cooperate with each other. The magnetic suction part 51 and the mating part 52 are magnetically connected. One of the magnetic suction part 51 and the mating part 52 is located at the other end of the mounting rod 3, and the other is located on the warning sign 4. In this embodiment, the warning sign 4 is magnetically installed onto the mounting rod 3 through the magnetic attraction between the magnetic suction part 51 and the mating part 52. The installation method is simple, reliable, and easy to disassemble.
[0037] Furthermore, a snap-fit structure is provided between the other end of the mounting rod 3 and the opposite end face of the warning sign 4. The snap-fit structure includes a mounting protrusion 61 and a mating groove 62 that cooperate with each other. The mounting protrusion 61 is installed into the mating groove 62. One of the mounting protrusion 61 and the mating groove 62 is located at the other end of the mounting rod 3, and the other is located on the warning sign 4. The magnetic suction part 51 and the mating part 52 are respectively located on the opposite end faces of the mounting protrusion 61 and the mating groove 62. In this embodiment, the mounting protrusion 61 and the mating groove 62 form a snap-fit contact between the mounting rod 3 and the warning sign 4. By placing the magnetic suction part 51 and the mating part 52 on the opposite end faces of the mounting protrusion 61 and the mating groove 62, it is ensured that the magnetic suction part 51 and the mating part 52 will magnetically engage with each other after the mounting rod 3 and the warning sign 4 are installed in place, thus ensuring the installation strength of the warning sign 4.
[0038] On the other hand, anti-retraction ribs are protruding on the circumferential sidewall of the insulating plug body 1, and the anti-retraction ribs extend circumferentially along the insulating plug body 1. In this embodiment, the insulating plug body 1 of the anti-misoperation insulating plug 100 is inserted one by one into the break gap of the already broken terminal connecting piece. In order to prevent the anti-misoperation insulating plug 100 from falling out of the break gap, anti-retraction ribs are protruding on the circumferential sidewall of the insulating plug body 1, so that an interference connection is formed between the insulating plug body 1 and the break gap, ensuring the connection strength of its insertion.
[0039] Furthermore, multiple anti-retraction ribs are provided, and these multiple anti-retraction ribs are spaced apart along the axial direction of the insulating plug body. In this embodiment, multiple anti-retraction ribs are provided to ensure the connection strength between the insulating plug body 1 and the break gap.
[0040] In addition, the anti-misoperation insulating plug 100 also includes an anti-detachment rubber ring 7, which is sleeved on the circumferential side wall of the insulating plug body 1, forming the anti-detachment rib. In this embodiment, the anti-detachment rubber ring 7 facilitates the formation of the anti-detachment rib on the circumferential side wall of the anti-misoperation insulating plug 100. It only requires sleeved onto the anti-misoperation insulating plug 100. Furthermore, it facilitates timely replacement when the anti-detachment rubber ring 7 is damaged, resulting in a simple and reliable structure.
[0041] Furthermore, an annular groove is recessed on the circumferential sidewall of the insulating plug body 1; the anti-detachment rubber ring 7 is fitted inside the annular groove and is at least partially exposed outside the annular groove. This ensures the connection strength between the anti-detachment rubber ring 7 and the insulating plug body 1, preventing them from falling off.
[0042] Furthermore, the portion of the anti-detachment rubber ring 7 exposed outside the annular groove extends away from the connecting end, forming an angle with the circumferential sidewall of the insulating plug body. In this embodiment, the portion of the anti-detachment rubber ring 7 exposed outside the annular groove forms a barb, facilitating insertion into the gap. Simultaneously, when the anti-detachment rubber ring 7 tends to detach, it naturally opens, providing a tighter fit and preventing detachment.
[0043] It should be noted that the cross-section of the portion of the anti-removal rubber ring 7 exposed outside the annular groove is triangular.
[0044] On the other hand, please see Figures 2 to 3 Multiple warning signs 4 are provided, each displaying a different warning image. Different warning signs 4 are selected to generate different prompts. During use, when implementing relay protection safety measures, the user inserts the anti-misoperation insulating plugs 100 one by one into the gaps of the disconnected terminal connectors, and selects one of the warning signs 4 as the warning, for example, selecting a warning sign 4 with a green "O" warning image. When restoring the relay protection safety measures, the person implementing the measures pulls out the anti-misoperation insulating plugs 100, connects the disconnected test terminal connectors, inserts the anti-misoperation safety plug into the other side of the connector, and replaces the warning sign 4 with a green "O" warning image with a warning sign 4 displaying a red "I" warning image. Thus, when the relay protection measures are implemented, the warning images of the anti-misoperation insulating plugs 100 on the implementing terminals are all green "O"s, and when the relay protection measures are restored, the warning images of the anti-misoperation insulating plugs 100 are all red "I"s. This allows for clear differentiation of the connection status of disconnection test terminal blocks among a large number of terminal blocks, and effectively prevents the occurrence of missing connections and loose connections.
[0045] It should be noted that the insulating plug body 1 is made of insulating rubber to ensure its insulation.
[0046] Similarly, the insulating insulating sheet 2 is made of insulating rubber.
[0047] Similarly, the mounting link 3 is made of insulating rubber.
[0048] It should be noted that, among the material settings of the above-mentioned insulating plug body 1, insulating isolation plate 2 and mounting rod 3, one can be selected or they can all be present.
[0049] In addition, the insulating rubber material is an insulating rubber material that conforms to national electrical standards to ensure its insulation strength. Different insulating rubber materials with different insulation strengths are selected according to different application scenarios to ensure that they are not broken down.
[0050] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
