An electronic connector is also called a circuit connector. An electrical connector Bridges two conductors of a circuit so that a current or signal can flow from one conductor to another.An electronic connector is an electrical system that provides a detachable interface for connecting two subelectronic systems. In simple terms, the components used to complete the interconnection of electrical devices such as circuits or electronic machines serve as a connector or a bridge between the two.

Electronic connectors are devices for the transmission of electronic signals (analog or digital signals). They provide separate interfaces for the connection of two subelectronic systems.Such as: power plug/socket, IC base, telephone plug, etc.Widely used in electronic industry.

An electronic connector is an electrical system that provides a detachable interface for connecting two subelectronic systems. In simple terms, the components used to complete the interconnection of electrical devices such as circuits or electronic machines serve as a connector or a bridge between the two.Electronics can be used as electrical/electronic transmission connecting parts between circuits, components and systems, enabling stable and reliable flow of power, signal and current, as well as convenient assembly, maintenance and replacement of products.


Materials for electronic connectors

The choice of materials is based on the comprehensive consideration of processing formability, product applicability and strength property.The cost of electronic connectors varies with the price of materials, the ease of processing and the efficiency of production.Electronic connector materials mainly include insulator materials (plastic materials), conductor materials (phosphor copper, brass);Electronic connectors are commonly used engineering plastics: LCP, NYLON, PBT.

1, the LCP

With small linear expansion coefficient, injection molding shrinkage rate and very prominent strength and elastic modulus and excellent heat resistance, has a high load deformation temperature, some can be as high as 340 degrees above, LCP also has chemical resistance and good air tightness, so the general connector especially SMT are preferred LCP material, eg:MINI PCI EXPRESS;DDR.

2, NYLON

Low cost, high tensile strength, excellent abrasion resistance and self-cressing, good fluidity, good for thin-wall forming, but severe shrinkage, easy to produce wool, strict baking before forming, in case of hydrolysis, general connector especially DIP mostly use NYLON, eg:PCI 120P;PCI EXPRESS.

3, PBT,

Low cost, high strength, friction resistance, but poor molding, shrinkage, due to low melting temperature, wave soldering will produce plastic melting phenomenon.


Development trend of electronic connector

1. The miniaturization

Small size, light weight, Pitch small, reduced height, high density/high Pin number.

2. High frequency signal/transmission

Contact group has low resistance, low effect, good signal shielding effect, signal delay, Crosstalk...., etc.

3. Automation

Reduce station process, Auto Pick & Place, Type, improve product accuracy, maintenance method.

4. User-friendly interface

User - friendly operation, anti - stay design.

5. Low use cost

Product standardization, flexible product and process design, delivery time compression [1].
