As an indispensable component in most product settings, the USB interface connector has developed rapidly in the market, with applications covering computers and their peripherals, tablets, smartphones, communications, smart home appliances, automotive, digital, monitoring, medical, and more. As a result, the market demand for USB interface connectors has doubled in just a few years. In order to give those who have just come into contact with USB interface connectors a simple understanding, today Dongdu Parts Manufacturer will talk about some small knowledge about the core material of USB interface connectors.

What should be noted when selecting the material of the rubber core in USB interface connectors? The terminals of the USB interface connector are made of metal and are charged during insertion and removal, so the rubber core of the USB interface connector needs to have good flame retardancy and flame retardancy. The commonly used materials for the rubber core in USB interface connectors include PBT, LCP, PA6T, PA9T, etc.

PBT: Its temperature resistance is around 220 ℃, and it has crack resistance, impact resistance, and electrical insulation capabilities. As a commonly used rubber core material in USB interface connector products, PBT also has excellent high heat resistance, fatigue resistance, and weather resistance. Moreover, if a little glass fiber fireproof material is added to PBT material, it also has excellent flame retardant properties.

LCP: This material has excellent heat resistance and formability, with a temperature resistance of around 260 ℃. LCP not only has excellent electrical insulation properties, but also excellent flame retardancy, corrosion resistance, weather resistance, and creep resistance.

PA6T: Its temperature resistance is around 290 ℃, and it has excellent welding resistance. PA6T is particularly suitable for electronic connectors used in surface mount technology (SMT). In addition, PA6T also has excellent high-temperature rigidity, chemical resistance, dimensional stability, flowability, etc.

PA9T: is a formed material with excellent heat resistance and the ability to withstand repeated friction and sliding resistance, with a temperature resistance of around 290 ℃. PA9T maintains good toughness even at high temperatures, making it superior to PA6T. Its low wear resistance and friction coefficient make it significantly better than other nylon materials, even surpassing LCP.
