What is a connector?
2022-12-20
An electrical connector, also known as a circuit connector, is a conductor device that bridges two conductors on a circuit so that current or signals can flow from one conductor to the other. An electrical connector is a motor system that provides a separable interface to connect two sub-electronic systems. Simply put, the components used to complete the electrical connection between circuits or electronic machines become the connector or the bridge between the two.
Electronic connectors are devices that transmit electronic signals (analog signals or digital signals) and provide a separable interface to connect two sub-electronic systems, and are components used to complete the electrical connection between circuits or electronic machines. Such as: power plugs / sockets, IC feet, telephone line plugs, etc. are. Widely used in the electronics industry.
Electronic connector is a motor system, which can provide a separable interface to connect two sub-electronic systems, in short, to complete the electrical connection between the circuit or electronic equipment and other components become the connector that is the bridge between the two. Electronic can be used as the electrical/electronic transmission connection between circuits, components, and systems, so that power, signal, and current can flow stably and reliably, and to facilitate product assembly, maintenance, and replacement.
Materials of electronic connectors
The choice of materials is based on processing and molding, product application and strength properties of a comprehensive consideration; the cost of electronic connectors by the price of materials, processing difficulties and production efficiency vary; electronic connector materials mainly contain insulator materials (plastic raw materials), conductor materials (phosphor bronze, brass); electronic connectors commonly used engineering plastic materials: LCP, NYLON, PBT.
1, LCP
Has a small coefficient of linear expansion, injection molding shrinkage rate is low and very outstanding strength and modulus of elasticity and excellent heat resistance, with high load deflection temperature, some can be as high as 340 degrees above, LCP also has chemical resistance and excellent airtightness, so the general connector especially the need for SMT are preferred LCP material, eg: MINI PCI EXPRESS; DDR.
2.NYLON
Lower cost, high tensile strength, outstanding wear resistance and self-slip, good fluidity, conducive to thin-walled molding, but shrinkage is serious, easy to produce hairy head, molding before baking strictly to prevent hydrolysis, general connectors, especially DIP most of the NYLON material, eg: PCI 120P; PCI EXPRESS.
3.PBT
Low cost, high strength, friction resistance, but poor molding, shrinkage is serious, due to the melting temperature is low, over the wave soldering will produce plastic melting phenomenon.

Electronic connector development trend
1. Miniaturization
Small volume, light weight, small Pitch, height reduction, high density / high Pin number.
2.High frequency signal/transmission
Low contact group resistance, low effect, good signal masking effect, signal delay, Crosstalk . etc.
3.Automated operation
Reduced workstation process, Auto Pick & Place, Type, product accuracy improvement, maintenance method.
4.User-friendly interface
User-friendly operation, anti-dumbing design.
5.Low cost of use
Standardization of products, flexible product and process design, compressed delivery time.
