Plastic Screws In Energy Storage Batteries

The plastic screws on the energy storage battery cover are used to fix the power circuit board. Since the power supply itself transmits power to other hardware through the interface plugged into the motherboard, if the power circuit board becomes loose or falls off, it will cause the power supply to fail. The purpose of plastic screws is to prevent the power circuit board from loosening or falling off due to vibration, and it can also insulate and shield electromagnetic interference. Therefore, plastic screws in energy storage batteries are very important.

Therefore, in the new energy lithium battery and energy storage battery industry, plastic screws will be chosen as commonly used fasteners. In addition, plastic screws also have a very important characteristic of good acid and alkali resistance, especially PVDF screws that are acid and alkali resistant. Nylon screws have great advantages in resistance to acid and alkali compared to PVDF screws, but their strength is higher. Therefore, plastic screws of different materials need to be selected for different usage conditions and environments to ensure the best cost performance and Practicality.

Many screws that have this kind of electroplating or work in such strong acid and alkali environments: PVDF screws, PEEK screws, NENY screws, nylon screws, PPS screws, PTFE screws, PAI screws, and PEI screws are widely used.

The energy storage battery is a lithium battery, which has extremely high requirements for temperature, sealing, and safety. Insulating plastic screws play an important role in the assembly process.

1. Prevent leakage, that is, over-current problems. The energy storage battery will pass the current test after the finished product is assembled. These over-current parts are usually terminal blocks. When the terminal blocks are not locked, it will cause poor contact at the terminal connections, resulting in Large resistance will cause local overload and heating, and may burn the terminals, so use plastic screws with good fastening properties to tighten them to avoid false fit.

2. In terms of sealing, plastic screws not only play a role in fastening connections, but also play a vital role in sealing. The design of plastic screws adds sealing elements such as sealing teeth, sealant and insulating gaskets.

Because plastic screws play an important role in energy storage batteries, every aspect of screw injection molding processing and production must be strictly controlled, quality standards must be adhered to, and customers' products can be protected.
