When the mounting hole for the stop pin is square, the mounting angle is limited to 90 degrees, and it is not possible to adjust the length of the rod. Therefore, it is necessary to keep stock of the rod in precise sizes. By changing the mounting hole for the stop pin to a star shape, it is possible to adjust the mounting angle by about 25 to 35 degrees. This expands the range for adjusting the length of the rod, allowing for a reduction in the number of rod lengths in stock. 【Features】 ■ Change the mounting hole for the stop pin from a square shape to a star shape ■ Adjustable mounting angle ■ Reduction in the number of rod lengths in stock *For more details, please refer to the catalog.

【Before】 Most of the latch is made of iron (SPCC + trivalent chromate treatment). The latch is a component that works in conjunction with the handle mounted on the door surface to lock and unlock the door. It is either hooked onto the frame inside the housing or in a pressed state, so it interferes with the frame during locking → unlocking and unlocking → locking. ↓ 【After】 By applying a resin coating to the part of the latch that interferes with the frame inside the housing, it alleviates snagging and rubbing during locking → unlocking and unlocking → locking. (It makes it easier to slide.) This also contributes to reducing the burden during the locking and unlocking of the door. *For more details, please refer to the catalog or feel free to contact us.

【Before】 ■Button-type handle The button-type handle eliminates the engagement between the lever and the button by pressing the button, allowing the lever to automatically rise due to the spring's reaction force. However, if the spring's reaction force is smaller than the load on the handle when closed, the lever becomes difficult to raise, which affects the door opening and closing operation. When adopting a button-type handle, it is necessary to check the load conditions in advance. ↓ 【After】 ■Manual handle The manual handle allows you to hook your finger behind the end of the lever and manually raise it. Since it is manual, you can reliably raise the lever even when there is a load on the handle, and it does not affect the door opening and closing operation. The adoption of a manual handle is particularly effective for addressing the issues that arise with the use of a button-type handle as mentioned above. *For more details, please refer to the catalog or feel free to contact us.

【Before】 ■Standard specification where the door's open/close status cannot be identified The handle attached to the main panel or metal casing is used to open and close the door. First, the key is inserted and turned in one direction to unlock or lock it. In a typical lock structure, it becomes difficult to visually determine whether the current state is locked or unlocked. ↓ 【After】 ■Indicator specification that allows identification of the door's open/close status An indicator displaying the locked/unlocked status will be provided near the key insertion area of the handle. It will show whether the current state is locked or unlocked. *For more details, please refer to the catalog or feel free to contact us.

【Before】 When attaching the handle to the door, a waterproof packing is installed between the door surface and the handle surface. Depending on how it is installed, the waterproof packing may protrude, so caution is needed during installation. The appearance and condition of the door may also affect its waterproof performance. ↓ 【After】 The waterproof packing installation surface on the handle side is designed to be "concave," allowing the waterproof packing to be installed (embedded type) in that "concave" shape, which prevents protrusion. Adjustments for protrusion during installation are also reduced, and it does not affect the appearance or waterproof performance of the door. *For more details, please refer to the catalog or feel free to contact us.

【Before】 ■Basic Specification Handle The handle for the enclosure and panel must be installed according to the width of the door, along with the latch. To do this, the latch must be manufactured to allow locking and unlocking on the enclosure side, which means it needs to be made according to the width of the door. If the height is insufficient in the basic specification, it will be necessary to perform a bending process on the latch. ↓ 【After】 ■Shaft Specification Handle By adopting a long shaft specification that allows for adjustment of the latch position (height), it is possible to apply it to various enclosures and panels without additional processing (bending) of the latch. This also reduces the variety of latches needed to match the specifications of the enclosure and panel. *For more details, please refer to the catalog or feel free to contact us.

【Before】 In the case of thin plates that cannot be processed for screws, additional work such as welding a separate part, a weld nut, to the hole processing area is required, which leads to increased costs for the overall production of the panel and enclosure. ↓ 【After】 When the plate is thin and cannot secure screw threads, it is possible to add thickness to the thin plate by performing a beading process. By raising the area around the hole, the range for screw hole processing becomes longer than the usual plate thickness for standard use. This contributes to the stability of the panel door operation. *For more details, please refer to the catalog or feel free to contact us.*

【Before】 In large distribution boards and control panels, many devices such as instruments and touch panels are mounted on the door surface, which creates a load on the door. In this case, the conventional pin for the drop-in hinge becomes difficult to remove when the door is under load, leading to an increase in labor during after maintenance. ↓ 【After】 By anticipating that a load will be applied to the door surface in advance, we create a step on the head of the drop-in pin for the hinge. This allows us to easily remove the drop-in hinge pin using this step. Even in poor installation environments for distribution boards and control panels, work can be performed safely and smoothly. *For more details, please refer to the catalog or feel free to contact us.*

【Before】 The hinges that are fastened with bolts have bolts welded in advance. This mechanism is designed to make it easier to work when securing the door. However, due to the welding process, there were many areas for improvement, such as the labor involved and the degradation of quality (in terms of appearance and precision) caused by spatter. ↓ 【After】 The Cellstat is a screw that can be installed on a base material with a thickness of 1mm or more simply by pressing it in. Unlike conventional iron hinges, it is manufactured by crimping through press fitting, which results in superior shape accuracy and appearance of the product. Furthermore, since it is a pressed product, it is also cost-effective, allowing for cost reductions in standard products. *For more details, please refer to the catalog or feel free to contact us.*

【Before】 ■Hinge with a plate welded to a pipe One structure of an integrated hinge is a hinge with a plate welded to a pipe. In the manufacturing of this hinge, it was necessary to first prepare the pipe and plate, cut them to the specified size, and then perform the welding process, which led to increased processing costs. 　↓ 【After】 ■Hinge with the tip of the plate curled By curling the tip of the hinge, it becomes possible to manufacture an integrated hinge. With this structure, only the bending process is required, eliminating the need for welding, which allows for a reduction in processing time and a decrease in the cost of the product itself. Improvements in the processing method can achieve cost reductions compared to conventional products. *For more details, please refer to the catalog or feel free to contact us.

【Before】 ■Bending Processing of Each Hinge Distribution boards and control panels come in various sizes depending on their applications. The shapes of the hinges used also vary widely, and multiple standard models are employed. This means that depending on the size and type of the panel, a variety of bending dimensions for hinges need to be kept in stock. ↓ 【After】 ■Flat Hinges By adopting flat hinges when designing panels, the standardization of mechanical components can be advanced. If flat hinges are used as a standard, even if the panel sizes vary, the hinges can be freely bent and used. This allows one type of hinge to accommodate multiple types of panels. *For more details, please refer to the catalog or feel free to contact us.

【Before】 ■Conventional Fixed Pillars Conventional fixed pillars are designed with screw processing, which makes the engagement of fixing screws not smooth. Depending on the machining accuracy of the panel, fixing with screws may not go well or may require more work. ↓ 【After】 ■Knurled Screws By using pillars with floating nuts or a floating nut specification, the engagement of knurled screws becomes smooth. Even if there is some misalignment during assembly, fastening with screws can be done easily, thereby simplifying the overall manufacturing process of the panel. *For more details, please refer to the catalog or feel free to contact us.

【Before】 ■2-pipe hinge It is commonly used as a concealed hinge for doors that are installed by welding pipes. However, depending on the size and weight of the metal casing, misalignment angles may occur, causing the door to open and close smoothly. ↓ 【After】 ■3-pipe hinge In the case of a 3-pipe hinge, there are two correction sections between the pipes, which can reduce misalignment angles compared to a 2-pipe hinge, allowing for smoother door operation. *For more details, please refer to the catalog or feel free to contact us.

• others

【Before】 Hinges that are fastened with screws or bolts typically have straight holes, but if the screw heads protrude from the surface, they may interfere with other components or negatively affect the appearance. ↓ 【After】 By changing the mounting holes of the hinges from straight holes to countersunk holes, the holes are recessed to a dish shape, allowing flat-headed screws to be fastened in that area, resulting in a flat surface for the hinges. This eliminates interference with other components and improves the appearance. *For more details, please refer to the catalog or feel free to contact us.*

【Before】 The conventional round bosses and round collars have a shape that makes it difficult to position them accurately when welding to the enclosure. As a result, if welding is performed at an incorrect position, the round bosses and round collars may become misaligned, leading to cases where securing them properly is challenging, which in turn increases the labor hours required. ↓ 【After】 In cases where effective use of internal space is necessary, such as in control panels where control devices are densely packed, corner collars, stepped bosses, and stud bosses are effective. By changing the shape of round bosses and round collars to corner collars, stepped bosses, or stud bosses, it becomes easy to position them accurately when welding to the enclosure. *For more details, please refer to the catalog or feel free to contact us.*

【Before】 ■Types of copper materials used in copper bars When using copper bars, while there may be a selection of surface treatments such as nickel plating or tin plating, there has been no consideration of the materials of the copper itself. As a result, we have been selecting and adopting copper materials without knowing whether they are suitable for the operating environment of our panels. ↓ 【After】 ■Types of copper materials used in copper bars and conductivity When selecting copper bars, determining the materials based on the internationally accepted annealed standard soft copper conductivity, known as IACS, allows for efficient current flow. While there may not be much difference in standard copper bars, it is possible to achieve energy savings by selecting custom copper bars designed to carry high-capacity power. *For more details, please refer to the catalog or feel free to contact us.

• Control Panel

【Before】 When determining the dimensions of copper bars used for carrying large currents, such as in power distribution boards, there were no clear internal standards, and we were directly repurposing from past drawings. The large cross-sectional area copper bars were not standard products from manufacturers, and we were ordering them as custom items each time, which led to high material costs for copper and processing costs for specified dimensions, becoming a problem. ↓ 【After】 The key points for selecting custom copper bars are that referring to the size charts from material manufacturers can help reduce processing costs. Since the dimensions of copper bars intended for carrying current do not require high precision in material dimensions, it is efficient to design them to match the original material dimensions as closely as possible. Although there is a standard length for each material, determining the dimensions of copper bars that do not require complex machining can achieve cost reductions. *For more details, please refer to the catalog or feel free to contact us.*

• Control Panel
• others

【Before】 The selection of the cross-sectional area of the copper bar based on the flowing current has been done using the catalog values from copper bar manufacturers. However, since the allowable current values differ among manufacturers even for the same cross-sectional area, we have prioritized safety by selecting larger cross-sectional areas of copper bars, which has led to increased material costs. ↓ 【After】 When determining the cross-sectional area of the copper bar based on the rated current, it is common to refer to the Japan Electric Power Control System Industry Association standard JSIA303 for cabinet-type distribution boards (III04-2). When prioritizing safety, it is possible to apply the above formula to select the necessary cross-sectional area. *For more details, please refer to the catalog or feel free to contact us.

• Control Panel
• others

【Before】 The copper bar determines its cross-sectional area (height × width) based on the flowing electrical capacity, but the "height" and "width" that determine the cross-sectional area are fixed combinations of standard dimensions. If the copper bar is designed outside the "height" and "width" specified in the table above, it will deviate from the standard product, resulting in increased costs and delivery times. ↓ 【After】 Once the required cross-sectional area of the copper bar is determined, the next step is to decide on the dimensions of the copper bar to be used. At this point, among the standard dimensions (height × width), for a "height" of 3mm, the "width" can be 12mm or 15mm; for a "height" of 4mm, the "width" can be 12mm, 15mm, or 20mm, etc. By selecting from standard copper bar dimensions, it is possible to achieve cost reduction and shortened delivery times for material procurement from the design stage. *For more details, please refer to the catalog or feel free to contact us.*

• Control Panel

【Before】 The criteria for selecting copper bars during the design of distribution boards and control panels is based on the current capacity (A) flowing through them, which tends to give the most weight to the cross-sectional area (width × height). Therefore, the "length" of the copper bars is often less considered, leading to an increase in the overall cost of the panel. Among them, the copper bars connected to the main breaker have a relatively large cross-sectional area, and three bars are required for three-phase systems, making it necessary to optimize the "length" of the copper bars themselves. ↓ 【After】 By understanding the "length" dimensions of standard raw material (at the time of purchase) copper bars, it becomes possible to design the optimal "length" of copper bars. Particularly when copper bars exceeding 600mm in "length" are required, it becomes difficult to obtain the three necessary copper bars for three-phase systems from a single raw material copper bar. By considering the number of bars obtained and the yield rate from the design stage, the cost of conventional copper bars was reduced by one-fourth. *For more details, please refer to the catalog or feel free to contact us.*

• Control Panel

【Before】 The ground terminal, which is electrically connected to the panel body and allows for the connection of the internal grounding wire and ground wire, is often installed on the ground within the housing. Therefore, if the mounting angle within a small electrical box cannot be secured, it can sometimes be difficult to perform the installation work for the ground terminal. ↓ 【After】 By cutting the leg portion of the ground terminal at an angle, a wider mounting angle than a right angle can be secured, making it easier to perform the installation work for the ground terminal even within a small electrical box. *For more details, please refer to the catalog or feel free to contact us.*

• Board materials

【Before】 The supporters and branching copper strips used inside the panel electrically connect the conductors. This can lead to the risk of electric shock, fire, and power loss. ↓ 【After】 By applying a coating to the components used inside the panel and insulating them, it is possible to prevent friction and electrical connections between the components, thereby enhancing the safety of the panel. *For more details, please refer to the catalog or feel free to contact us.*
