What are the plastic materials for production connectors

When making a connecter product, there will always be plastic materials when you need to use plastic materials. What are the plastic materials used when introducing the connector production? What are the requirements of these materials to meet the requirements of car connectors? As far as the material is concerned, the plastic raw materials commonly used in connectors mainly include PBT, 66, 6T, 9T, LCP, etc. These materials are different in quality, temperature resistance, and price. Of course, these differences are also. It will be reflected on the price of the connector.

 

1. PBT plastic material

PBT plastic materials are often used on the production of 2.54 pitch 180 degrees/90 degrees of parent connector products. The welding temperature of the plastic terminal shell is only about 200 degrees. Because the cost is relatively low, high in strength, friction resistance, etc. Now there are many customers who choose this material. However, the use of this material is poorly molded, severe shrinking, due to low melting temperature, and plastic melting phenomenon when welding is over -welded.

 

2. Nylon-66. A kind of armoplastic resin. White solid. Density 1.14. The melting point is 253 ° C. Involved in general solvents, soluble only in phenylphenols, etc. The mechanical strength and hardness are high and rigid. Can be used as engineering plastics. Lowl Hardness 108-118. Thermal deformation temperature (1814.11 Pa, 18.5 kg/cm 2) 66-86 ° C. Used as mechanical accessories, such as gears and lubrication bearings; replacing non -ferrous metal materials for machine shells, car engine blades, etc. It can also be used to make fiber.

 

3. 6T plastic material

Connector manufacturers said that this material is generally used in the 2.54 spacing patch patch mother, and the 1.27 spacing/2.0 spacing series of mothers. The welding temperature is between 260 degrees and 290 degrees, so the cost of the excrement connectors produced by this material is slightly higher. Choosing this material is generally a customer's quality requirement.

 

4. 9T plastic material

Most of the connected products of this type of material are 2.54 spacing patch patch puppets, and the 1.27 spacing/2.0 spacing series of mothers. The welding temperature is about 260-degree-300 degrees. Because the use of this material is expensive, it is generally used by customers to use 9T plastic materials to produce connector products.

 

5. LCP plastic material

For the production of the products of the parent car connector products that are suitable for a variety of spacing series, the welding temperature is between 260 degrees and 320 degrees. This material has a small expansion coefficient, low injection molding rate, low strength and elastic modulus, excellent thermal resistance, high load deformation temperature, and excellent chemical resistance and qi tightness. Therefore Those who need SMT prefer LCP materials.

However, corresponding to the same, the price of connecting products with such materials will be higher, because the price of the material itself is expensive, and the process of the car connecter product manufacturer is needed. Therefore There are this request.
