More specifically, it relates to a device comprising an insulation structure that safely inserts a wire into the lower part of an electric power meter, enables contact only between phases, and prevents physical contact with grounding or other phases. Background Technology

[0002] The risk of electric shock and safety issues that may occur during wire insertion and work are critical considerations in the installation and maintenance of electricity meters and electrical facilities. As a device that measures electricity usage, an electricity meter ensures accurate measurement and power supply based on the wire connection status. However, accidents such as electric shock or short circuits can occur if a worker incorrectly contacts the voltage or phase terminals of the meter during the wire insertion and connection process, or if the wire becomes mixed with nearby wires and grounded. To address these issues, there is a growing need for an insulating structure that physically isolates the terminals from other phases and ground during wire insertion. While existing wire connection structures could ensure a certain level of safety, unexpected safety accidents frequently occurred in various fields due to reckless handling by workers or incomplete wire insertion. Therefore, a new type of guiding insulation device is required to enable accurate and safe connections during wire work, thereby reducing the risk of electric shock and preventing wire detachment. In particular, safety features are being emphasized that ensure only the phase terminals make accurate contact when the wire is inserted into the bottom of the electricity meter, while reinforcing physical isolation from other phases or ground. Against this backdrop, the present invention aims to provide a guiding insulation mechanism that helps to accurately and safely insert a wire into a power meter, thereby preventing various safety accidents that may occur during the wire insertion process.

[0004] In conventional power meters, the process of inserting and connecting wires requires skilled workers, and there is a risk of safety accidents if wires are inserted incorrectly or if contact occurs between different phases. Additional work is required if the wires become detached or damaged during connection, and risks due to unnecessary electrical contact or insulation failure persist during the process. Therefore, the problem that the present invention aims to solve is to provide a wire insertion safety guiding insulation device that can significantly improve work safety during the wire insertion and connection process of a power meter and prevent electrical accidents by strengthening insulation. Another problem that the present invention aims to solve is to provide a safety system that prevents physical contact with terminals of other phases or ground by ensuring that only the terminals of each phase make accurate contact when inserting wires. Furthermore, another problem is to provide a device that combines a fixing structure and an electrical insulation function to safely maintain wires that have become detached or are incorrectly connected after connection. means of solving the problem

[0005] To solve the above problem, the present invention is a wire insertion safety guiding insulation device characterized by comprising a wire insertion opening at the bottom of a power meter, an isolation / insulation part (100) located at a terminal part connected through the wire insertion opening and a front tightening bolt, and a clamp / grip part (200) fixedly attached to the power meter.

[0006] In one embodiment of the present invention, the isolation / insulation part (100) is configured to contact only the phase terminals when a wire is inserted, thereby physically isolating it from the terminals of other phases or ground. Additionally, the isolation / insulation part (100) includes a removal hole (102) to prevent wire detachment and to ensure the wire is effectively fixed even if the wire is detached after fastening, and has a conical insulating wing (101) inside that is narrow at the top and wide at the bottom to provide stable insulation and guiding. The material of the isolation / insulation part (100) is made of flame-retardant synthetic resin or transparent polycarbonate to enhance durability and electrical safety. The isolation / insulation part (100) can be fixed via a clip (104) that is inserted and attached to the bottom surface of the power meter, and the clamp / grip part (200) provides strong tensile force to be firmly attached to the power meter. The insertion hole within the isolation / insulation section is designed to provide an inner diameter of Φ12mm so that wires of various thicknesses can be suitably inserted. In another embodiment of the present invention, the wing (101) of the hollow conical isolation / insulation section is formed with an inclined surface that is narrower at the top and wider at the bottom on both the inner and outer surfaces, and a guide (103) is provided on the wing, which is open at a certain angle, to facilitate wire insertion. Effects of the invention

[0007] The wire insertion safety guiding insulation device according to the present invention provides an improved insulation structure that enables a safe and efficient connection when inserting a wire at the bottom of a power meter. In particular, it is equipped with an insulating wing (101) that allows only contact between phase terminals through the isolation / insulation section (100) and physically isolates it from other phase terminals or ground, thereby ensuring safe operation. This prevents electrical collisions and ensures electrical stability.

[0008] In addition, materials such as flame-retardant synthetic resin or transparent polycarbonate are used to provide additional fire prevention effects, while the transparent material allows for intuitive visual recall of the operation. It can be securely fixed to the power meter via the clamp / grip part (200), preventing the device from detaching during operation and further enhancing the safety of the worker. Through the removal hole (102) when inserting the wire, the wire is prevented from detaching even after fastening, and the fastened state is maintained even if the wire is detached, thereby increasing the protective effect. In particular, the conical insulating wing, which is narrow at the top and wide at the bottom, facilitates the insertion and fastening of the wire during operation, while simultaneously preventing conductive contact between different phases, thereby ensuring electrical safety.

[0009] Therefore, the wire insertion safety guiding insulation device of the present invention maximizes safety and convenience during power work and ensures the safety of workers, thereby having the effect of significantly reducing risk factors that may occur in conventional power meter wire connection work. Brief explanation of the drawing

[0010] Figures 1 to 6 are structural diagrams of a wire insertion safety guiding insulation device. Specific details for implementing the invention

[0011] FIGS. 1 to 6 are drawings specifically illustrating the structure of a wire insertion safety guiding insulation device. The insulation device for preventing wire short circuit (ground fault) accidents during power meter replacement (new installation) work according to an embodiment of the present invention includes an isolation / insulation section (100). The isolation / insulation section (100) is positioned on the bottom surface of the power meter to prevent short circuit accidents that may occur during the wire connection process in a structure where the phase wire insertion terminals are close together. The isolation / insulation section (100) is composed of a wing (101), a guide (103), a plug (104), and a removal hole (102), and is manufactured from a synthetic resin with sufficient flame retardant dielectric strength, transparent polycarbonate, or an equivalent or superior material. The wing (101), together with the guide (103), ensures isolation and insulation so that a live wire (lead wire) can be inserted only into the corresponding phase of the power meter. The guide (103) guides the direction so that the wire flows only along the intended path, thereby preventing interference or unnecessary movement when the worker inserts the wire. Additionally, a plug (104) is used to easily and securely attach the insulating device to the bottom surface of the power meter, and the plug (104) is designed to allow for easy detachment even after the insulating device is fixed. It is a protruding structure that is fixed to the part corresponding to the bottom surface of the power meter, providing stability.

[0012] After the wire connection is completed, the wire can be removed through the removal hole (102) when removing the insulating device. The removal hole (102) is a hole provided to safely remove the wire and is a structure added to allow the worker to separate the wire more easily. The hole of the isolation / insulating part (100) can be made with a diameter of Φ12 mm to ensure a clearance and versatility.

[0013] The present invention relates to a wire insertion safety guiding insulation device for preventing electrical accidents that may occur during the wire insertion process and for ensuring safety. It is designed to prevent incorrect contact between a wire and a terminal or short circuits between surrounding terminals when connecting a wire to a terminal of an electric power meter or an electrical device. In particular, the insulation device provides a function to prevent accidental electrical connection accidents or wire detachment that may occur during wire insertion.

[0014] The present invention is a wire insertion safety guiding insulation device for improving safety when inserting a wire into a wire insertion port located at the bottom of a power meter. It includes an isolation / insulation unit (100) that provides isolation and insulation functions to safely perform the connection process between the wire insertion port formed at the bottom of the power meter and a terminal unit fixed via a front tightening bolt. The isolation / insulation unit protects the user from electrical hazards while the wire is being inserted and serves to prevent electrical accidents that may occur during the insertion process. Additionally, the present invention includes a clamp or gripping unit (200) that can be fixedly attached to the main body or exterior of the power meter. The clamp / grip unit provides support and stability so that a worker can easily insert and secure the wire. Through this, it induces accurate insertion and assembly into the terminal unit, and technical effects can be expected to prevent accidents that may occur during power meter operation.

[0015] In one embodiment of the present invention, the isolation / insulation section (100) is a structure designed to ensure that when the wire is inserted, it makes accurate contact only with the phase terminals of the corresponding power meter. The isolation / insulation section exists to prevent unnecessary contact or short circuits during the wire insertion process, thereby improving electrical safety, minimizing the possibility of malfunction or accidents, and increasing the reliability of the system. Additionally, the isolation / insulation section includes a function to prevent incorrect contact during the process of mounting or installing the wire by the user, and performs the role of guiding contact with the phase terminals of the wire only at designated locations. Such a structure contributes to enhancing safety during installation and maintenance, particularly by preventing electrical shock during work while current is flowing, and enables safer and more efficient wire connections.

[0016] The guiding insulation mechanism of the present invention for ensuring safety during wire insertion is characterized by comprising an insulating wing (101). The insulating wing (101) is designed to be physically isolated from the terminal or ground connected to the wire, thereby serving to prevent the risk of leakage current or electric shock caused by current flow. The insulating wing maintains separation by forming a physical barrier to prevent contact with the terminal or ground, thereby providing a function to prevent electrical problems that may occur during the wire insertion process. The insulating wing is made of a robust and electrically insulated material and is structured to ensure stability so that electrical performance can be maintained over time. In addition, the wing is appropriately placed along the path where the wire is guided to help the user insert the wire without accidentally contacting other electrical circuit components and to help the wire be positioned accurately. Therefore, the present invention has the advantage of ensuring insulation safety while the user connects or inserts the wire, while simultaneously improving the ease of operation.

[0017] The isolation / insulation part (100) of the present invention is an important component of the wire insertion safety guiding insulation device, and the material of the corresponding part is formed from flame-retardant synthetic resin or transparent polycarbonate. The selection of such materials is one of the measures to improve safety; flame-retardant synthetic resin has the property of preventing the spread of flames, thereby playing a role in ensuring safety in the event of a fire. In addition, transparent polycarbonate provides excellent mechanical strength and the characteristic of being able to transmit light, allowing the internal structure to be visually confirmed and facilitating visual inspection by the user. These materials possess durability and heat resistance, helping the device to operate stably even in harsh working environments. Therefore, the isolation / insulation part of the present invention is composed of functional and safe materials, playing an important role in preventing safety accidents related to wire insertion.

[0018] The wire insertion safety guiding insulation device of the present invention includes a structure designed so that an isolation / insulation part (100), which performs isolation and insulation functions, can be stably inserted and secured to the bottom surface of a power meter. In particular, a plug (104) is formed in the isolation / insulation part, and the plug serves to guide the user to easily insert or secure the isolation / insulation part to the bottom surface of the power meter. This plug structure ensures an accurate connection between the power meter and the isolation / insulation part, and provides a function that enhances safety by maximizing the effect of electrical insulation. This configuration of the present invention is designed for the purpose of reducing the risk of electric shock that may occur during electrical work and ensuring the safety of the worker.

[0019] The present invention relates to a wire insertion safety guiding insulation mechanism that allows a wire to be safely inserted through a wire insertion port located at the bottom of a power meter and enables the inserted wire to be firmly fixed to a terminal part of the power meter.

[0020] The isolation and insulation part (100) of the present invention performs the role of fixing and insulating the wire before it is connected to the terminal part of the power meter, and is designed with a structure to prevent the wire from falling off. The isolation / insulation part (100) is an insulating mechanism designed to stably maintain this fastening state when it is fastened to the terminal part through the front tightening bolt of the wire coming out of the wire insertion opening, and has the function of preventing the wire from coming off even after the wire is fastened. In particular, the isolation / insulation part (100) of the present invention includes a removal hole (102) coming out of the wire, so that it does not come off even after being fastened to the terminal part of the wire. Even if a detachment occurs, the already fastened state of the wire can be safely maintained, thereby further enhancing the stability of the electrical connection. In addition, the clamp / grip part (200) of the present invention facilitates the fixing and fastening with the power meter and acts as a guide so that the wire can be clearly inserted and managed. Through this, the purpose is to reduce accidents or problems that may occur during the connection of the wire and to further enhance the safety of the worker and the equipment.

[0021] The wire insertion safety guiding insulation device of the present invention is characterized by including a structure designed so that the clamp / grip portion (200) can be firmly attached to the power meter. At this time, the tensile force, i.e., the resistance force of the clamp (201), is sufficiently secured to maintain a stable attachment state to the power meter. This tensile force is guaranteed through the structural design of the clamp and serves to prevent the attachment state from easily loosening due to external forces or impacts that occur when the clamp is attached to the power meter. Therefore, the present invention can be described as an insulation device equipped with the function of improving safety during wire insertion and maintaining a reliable connection with the power meter, thereby enhancing attachment to power measuring equipment while contributing to the protection of wires or equipment.

[0022] The wire insertion safety guiding insulation device of the present invention has a structure in which a clamp or gripping part (200) is integrally provided with an isolation or insulation part (100). This structure is an efficient design for safely fixing and isolating wires, and since the clamp or gripping part (200) is integrally formed with the isolation or insulation part (100), errors or detachment that may occur during the wire insertion and gripping process can be minimized using the integrated parts without a separate joining process.

[0023] The integrated design of the present invention simplifies the mechanism by eliminating the need for precise spacing adjustment between the gripping part and the insulating part when inserting a wire, while simultaneously providing the advantage of improving electrical insulation performance. This integrated structure not only simplifies the overall manufacturing process and reduces costs but also enhances reliability during field operations. Therefore, the insulating mechanism of the present invention features the ability to safely insert and secure wires, and is a structure capable of providing excellent effects in terms of electrical insulation and gripping performance.

[0024] The isolation / insulation section (100) of the present invention is an insulating device having a structure designed to minimize electrical interference from the outside and induce safe insertion of a wire. In particular, the inner diameter of the hole formed in the isolation / insulation section (100) is 12 mm, which is a dimension designed considering the diameter or sheath thickness of a typical wire. This diameter of the hole prevents excessive friction or resistance when inserting a wire, allowing for easy insertion, while maintaining electrical insulation performance by not allowing an excessively large space. In addition, the inner diameter of Φ12 mm ensures that the wire is properly fixed within the insulation section, thereby providing stability that prevents shaking or damage to the wire caused by external shocks or vibrations. Consequently, the insulating device according to one embodiment of the present invention is a structure that enhances safety and induces easy insertion of a wire, while simultaneously exhibiting an appropriate electrical insulation effect.

[0025] The wire insertion safety guiding insulation device of the present invention provides a device for safely and efficiently performing wire connection work, and is characterized in that it is naturally pulled out through the wire removal hole (102) during the process of removing the insulation device after the wire connection is completed. It serves as a guide so that the worker can safely handle the wire even when the insulator is not transmitting current, and this is closely related to the structure designed to securely fix the wire after connection and allow the wire to be easily removed during the finishing work. Thanks to these structural features, unnecessary damage or excessive manipulation by the worker is not required during the wire removal process, which plays an important role in maximizing work efficiency while ensuring safety during work.

[0026] The present invention relates to a wire insertion safety guiding insulation device that ensures safety and provides insulation functions when inserting a wire through a wire insertion port installed at the bottom of a power meter. The device acts as an obstacle to prevent the wire connected to the power meter from directly contacting the terminal, and in the process, it has the function of inducing safe wire insertion. In one embodiment of the present invention, an isolation / insulation unit (100) that performs isolation and insulation functions is located at the terminal, which is fastened via a front tightening bolt along with the wire insertion port. The isolation / insulation unit guides the wire to make accurate contact with the terminal and simultaneously performs the function of protecting the user from electrical hazards that may occur when inserting the wire. In addition, the isolation / insulation unit has a unique structural feature. The isolation / insulation unit includes a wing (101) characterized by a conical shape that gradually narrows in width in the vertical direction, thereby performing the function of naturally and stably guiding the insertion direction when the wire is inserted. This conical wing structure has the advantage of minimizing the risk of the wire slipping out or malfunctioning when the user inserts the wire.

[0027] There is a clamp or gripping part (200) that is fixedly attached to the power meter of the present invention. The gripping part functions to fix the structure so that it does not move during the wire insertion process by maximizing the stability of the mechanical connection with the power meter. As a result, it is guaranteed that the work is performed accurately without shaking or instability during wire insertion and fastening.

[0028] Accordingly, the present invention is a safety guiding mechanism for safely and accurately inserting a wire into an electric power meter, and is a structure having the technical advantage of enabling a user to connect the wire more safely and quickly through the combination of a conical wing structure of an isolation / insulation part and a gripping part that provides binding stability.

[0029] The present invention relates to a guiding insulation mechanism for maximizing safety during wire insertion. In one embodiment, the mechanism is designed so that a portion of the wing can be opened at a certain angle, thereby helping the user perform the task more easily and safely when inserting the wire. The opening of the wing is performed at a certain angle, thereby minimizing resistance or friction during the wire insertion process while faithfully serving as a guide. Additionally, a guide (103) is formed at a certain height on the opened wing, providing a function for the guide to precisely guide the wire when it is inserted, and as a result, the insertion position and direction can be accurately adjusted. This configuration contributes to reducing unnecessary errors that may occur during wire insertion, preventing damage to the wire, and effectively ensuring the safety of the worker.

[0030] The guide (103) of the present invention is a wire insertion safety guiding insulating mechanism formed by extending to the end of the wing (101) to enable the wire insertion operation to be performed more safely and efficiently. The wing (101) may be composed of a material having insulating properties to minimize external impact or interference when the wire passes through and to ensure electrical safety. In addition, the guide (103) functions to guide the wire to be inserted into the correct position, prevents irregular movement that may occur during wire insertion, and provides structural stability to prevent the wire from coming off the wing (101). This ensures that the wire insertion operation is performed more safely during the process and serves to improve the overall electrical performance and safety of the device.

[0031] The present invention relates to an insulating device for enhancing safety during wire insertion, and specifically features a technical configuration for easily inserting a wire into a wire insertion port located at the bottom of a power meter, preventing safety accidents during the wire insertion process, and maintaining an electrically insulated state. In one embodiment of the present invention, the wire insertion safety guiding insulating device is composed of four main components. First, there is a wire insertion port formed at the bottom of the power meter as the place where the wire is inserted. This wire insertion port is structured to facilitate the insertion of the wire and provide a space for the wire to be inserted, thereby ensuring that the wire connection work can be performed safely. Second, an isolation / insulation part (100) that performs the role of isolation and insulation is located at the terminal part where the wire is fastened through this wire insertion port and a front tightening bolt. This isolation / insulation part is an important component that ensures the insulation and electrical safety of the wire, thereby preventing the worker from being exposed to unexpected electrical accidents. Third, there is a clamp or gripping part (200) that is fixed to the power meter and securely attached. This helps to ensure that the wire is accurately inserted and remains fixed in one embodiment of the present invention, and ensures that the wire remains fixed in the correct position even after insertion or connection. Fourth, a hollow conical wing (101) is formed in the isolation / insulation section (100) so that the wire can be guided by itself. This hollow conical wing (101) maintains the direction of the wire consistently when the wire is inserted, and prevents the wire from coming out of the insertion opening or entering in the wrong direction, thereby realizing safe wire insertion.

[0032] The present invention provides a wire insertion safety guiding insulation device comprising a wire insertion port, an isolation / insulation part, a clamp / grip part, and a hollow conical wing to maximize worker convenience and electrical safety during wire insertion and fastening operations.

[0033] The wire insertion safety guiding insulation mechanism of the present invention employs a wing structure to maximize safety and work efficiency during the wire installation process. The wing is formed with an inclined surface that is wider at the top and narrower at the bottom on both the inner and outer sides. This wing structure enables the wire to be guided more smoothly during insertion and serves to suppress damage to the wire or malfunction during the insertion process. As a result, the wire can be safely inserted into the mechanism, and the risk of detachment or damage due to external impact or pressure after insertion can be minimized.

[0034] The wire insertion safety guiding insulation device of the present invention is mainly composed of an isolation / insulation section (100) and a clamp / grip section (200). The isolation / insulation section (100) is located at the terminal section through a wire insertion opening into which a wire is inserted and a front tightening bolt, and is an important part equipped with an insulation function that can prevent contact between terminals. In addition, the isolation / insulation section (100) is configured to physically isolate the wire from terminals or ground of a different phase, and includes an insulating wing (101) for this purpose. The insulating wing (101) is designed in a conical shape that is narrow at the top and wide at the bottom, that is, narrow at the top and wide at the bottom, to ensure tight contact after the wire is inserted and secured. This structure effectively blocks short circuits that may occur between adjacent terminals. The material of the isolation / insulation section (100) is mainly composed of flame-retardant synthetic resin or transparent polycarbonate. These materials prevent fire even at high temperatures and provide a function that allows the insertion status of the wire to be visually inspected through transparency. Additionally, the isolation / insulation part (100) can be inserted and attached to the bottom surface of the power meter through a plug (104) so ​​that it can be stably fixed to the bottom part of the power meter.

[0035] The wire insertion safety guiding insulation mechanism of the present invention includes a removal hole (102) as an additional safety device to prevent the wire from coming loose. The removal hole (102) is designed to maintain a fixed state even if the wire is incorrectly connected or detached due to an accident, thereby preventing a major accident even if the wire is removed from the terminal part.

[0036] The clamp / grip portion (200) functions to allow the insulating device to be firmly fixed to the power meter, and is stably attached to the power meter through the clamp (201). It is a structure in which a clamp designed to secure the necessary tensile force (resistance force) so as not to be easily removed is attached.

[0037] The clamp / grip part (200) may be configured as an integral part with the isolation / insulation part (100), and each part is configured to operate as an integral part to make installation and maintenance easier. In addition to the structure described above, the inner diameter of the hole in the isolation / insulation part is designed to be Φ12mm so that most wire thicknesses can be used without difficulty, and the wire can be safely pulled out through this hole when removed after fastening.

[0038] In addition, when the insulating device is no longer needed after the wire connection is completed, the wire is safely removed through the removal hole (102), thereby simplifying maintenance work. Meanwhile, the insulating wing (101) in the isolation / insulating section (100) is designed as a hollow cone shape, making it easy to insert the wire. Furthermore, the insulating wing, which is narrow at the top and wide at the bottom, has both its inner and outer surfaces formed as inclined planes, which helps insert the wire while maintaining its directionality and guides it to prevent the wire from falling out. Some of the wings are opened at a specific angle, and a guide (103) is added thereto to assist in the three-dimensional movement of the wire. The guide (103) extends to the end of the wing (101) to help insert the wire more easily and quickly. Therefore, the wire insertion safety guiding insulating device of the present invention is an effective device designed to safely connect wires to power meters or other electrical devices, providing a structure with significantly enhanced insulation and safety. These functional characteristics can prevent electrical accidents that may occur during wire connection work, ensuring not only worker safety but also the stability of electrical facilities.
