Plastic materials for the production of connectors
In the production of connector products, there will always be a need to use plastic material, connector production, the use of plastic material? These materials need to meet the requirements of automotive connector products? On the production of material, connector commonly used plastic raw materials are mainly PBT, 66, 6T, 9T, LCP and so on, and these materials are different in quality, temperature performance and price, of course, these differences will also be reflected in the connector price.
1. PBT plastic material
PBT plastic materials are often used in the production of 2.54 spacing 180 degrees /90 degrees of female connector products, plastic terminal shell welding temperature is only about 200 degrees, due to the low cost of other materials, high strength, friction resistance and other characteristics, now this material still has a lot of customers to choose. But the use of this material has poor formability, serious shrinkage, due to the low melting temperature, over wave welding will produce plastic melting phenomenon.
2. Nylon-66. A thermoplastic resin. White solid. The density of 1.14. Melting point is 253 ℃. Insoluble in general solvents, only soluble in m-cresol, etc. High mechanical strength and hardness, great rigidity. Can be used as engineering plastics. Rockwell hardness 108-118. Thermal deformation temperature (1814.11 pa, 18.5 kg force/cm 2) 66-86℃. Used as mechanical accessories, such as gears, lubricating bearings; Instead of non-ferrous metal materials to do machine shells, car engine blades and so on. It can also be used to make synthetic fibers.
3. 6T plastic materials
Connector manufacturers say this material is generally used for 2.54 pitch patch bars and 1.27 pitch /2.0 pitch series bars. The welding temperature is between 260 degrees and 290 degrees, so the cost of using this material to produce the busbar connector is slightly higher, the choice of this material is generally the customer quality requirements on the product.
4. 9T plastic
Connector products that will use this material are mostly 2.54 pitch patch bars and 1.27 pitch /2.0 pitch series bars. The welding temperature is about 260 degrees to 300 degrees. Due to the high price of this material, 9T plastic material is generally used to produce connector products with special needs of customers.
5. LCP plastic
Suitable for the production of a variety of spacing series of bus car connector products, welding temperature between 260 degrees -320 degrees. This material has small linear expansion coefficient, low shrinkage rate of injection molding, good strength and elastic modulus, excellent heat resistance, high load deformation temperature, but also excellent chemical resistance and air tightness, so the general connector especially need SMT are preferred to choose LCP material.
However, corresponding to the use of this kind of material connector product price will be higher, because the price of the material itself is expensive, in addition to the need for automobile connector product manufacturers to cooperate with the process, so the use of this material is generally special customers have this requirement.
