Plastic screws have high electrical resistance and excellent insulation properties. By using plastic screws with superior insulation, it is possible to prevent short circuits. ● Heat Resistance: Materials such as PPS (polyphenylene sulfide) and RENY (polyphenylene sulfide-based resin) have a heat resistance temperature of over 200°C, providing stable performance even under harsh temperature conditions. ● Insulation: Plastic screws have low thermal conductivity and excellent insulation properties. They can prevent localized condensation caused by thermal bridges. This enables efficient thermal management in the design of equipment and devices where temperature control is crucial. ● Lightweight: Plastic screws are very lightweight, making them suitable for products and equipment where weight reduction is necessary. ● Corrosion Resistance: Plastic screws do not rust or corrode, offering excellent resistance to moisture and chemicals. ● Electrical Insulation: Plastic screws have high electrical resistance and excellent insulation properties. By using plastic screws with superior insulation, it is possible to prevent short circuits.

At Hiroseki Instrument Co., Ltd., we handle two types of "insert nuts": screw-in type and press-fit type. The "screw-in type" is an embedded nut used for reinforcing or repairing screw holes in materials such as plastic, light metals, and steel plates. It can also be utilized for reprocessing defective female threads in plastic, light metals, steel plates, and products through tapping. When the strength of the female thread is weak and cannot provide sufficient tightening force during tapping, inserting this nut allows for reliable screw fastening. The "press-fit type" is an insert used after resin molding, which is inserted into a formed hole during molding using press-fit or heat press methods to create threads. *We also handle "insert collars" (for press-fit and simultaneous molding). 【Screw-in Type Insert Nut Features】 ○ Machined with high precision on NC automatic lathes, ensuring stable quality after insertion. ○ Easy for anyone to insert, resulting in high-strength female threads in a short time. ○ Using a locking mechanism during insertion increases the fixing strength of the product, allowing for reliable screw fastening. ○ Fixed by screwing into a pre-tapped hole using an insertion tool.

The "Battery Holder CDH" is a battery holder that mounts coin batteries onto printed circuit boards. Once the battery is installed, it is securely held in place, making it unlikely to come loose and eliminating concerns about poor contact. When removing or replacing the battery, it can be easily detached by gently pressing the central tab with a finger or pen tip. There are two types available: through-hole pin type and surface mount type. [Types] ○ CDH-100: For through-hole pin mounting (66 nylon) ○ CDH-200: Surface mount type (66 nylon) ○ CDH-300: For through-hole pin mounting (66 nylon) ○ CDH-400: For through-hole pin mounting (PBT) ○ CDH-500: Surface mount type (PPS) For more details, please contact us or download the catalog.

The "Power Terminal HP" is a power supply terminal that is mounted on a circuit board by inserting and soldering. There are 9 types available for installation from the top or side, with two surface treatments: gold plating and tin plating. The use of lug terminals makes wiring easy. The "Power Terminal (Insulated Type) MIS" is a spacer that is soldered to the circuit board. It can be securely fixed by inserting four pins into the circuit board. Since the pins are integrated into a resin base, there is no short circuit even if they come into contact from the side. It is also possible to install a lug terminal and supply power from the circuit board. 【Features】 [HP] ○ Four types of mounting screw sizes: M2, M2.6, M3, M4 ○ By adding an S at the end of the part number, mounting screws with gold or tin plating are included [MIS] ○ Using separately sold PPS small screws further enhances the insulation effect ○ Screw diameters of M2, M2.6, M3, with heights available in 4, 6, 8, and 10 For more details, please contact us or download the catalog.

The "adjustment component terminal" is a terminal for mounting adjustment components such as resistors and capacitors. Instead of placing the adjustment components on a groove, they are designed to be stable and less likely to fall off even before soldering, thanks to the thoughtfully designed hole shape. During soldering, the pins are tilted, allowing for better visibility of the soldering tip. When removing the mounted adjustment components, even if the opening of the C-shaped hole is obscured by solder, you can confirm it by the mark (notch) on the pin. 【Features】 ○ Pins can be mounted on the board at your preferred pitch, available in 10 colors (Part number HOC) ○ Two pins are integrated into the base for improved workability (Part numbers HOV・HOS) ○ Available in 6 types of pitch and 6 colors each (Part numbers HOV・HOS) ○ Melted solder is less likely to flow away due to the hole shape and the tilt of the pins (Part number HOS) For more details, please contact us or download the catalog.
