Before purchasing the connector, I wonder if you have an understanding of the basic performance, classification and basic elements of the connector? If not, then, take a look at our article today!

　　The basic performance of the connector can be divided into three categories: mechanical performance, electrical performance and environmental performance.


　　1. Mechanical properties Insertion and extraction force Insertion and extraction force is divided into insertion force and extraction force, retention force (if the retention force is too small, it will affect the reliability of the connection), durability (lifetime)

　　2. Electrical performance: The main electrical performance of the connector includes rated voltage, rated current, contact resistance, insulation resistance and dielectric strength (withstand voltage).

　　3. Environmental performance Common environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance, tin adhesion, etc.


　　How to classify connectors?

　　According to gender: male end, female end (plug, socket; SOCKET, HEADER, male, female)

　　According to the occasion of use: board end, line segment, backplane

　　According to the connector mode: BTB, WTB, WTW

　　According to the connector type: USB, RJ, DB, FPC, European style

　　According to the welding method: DIP, SMT CLIP (splint type), IDC (wire piercing), PRESS FIT (socket type)


　　What are the basic elements of the connector?

　　Pitch: Determined according to design requirements to meet design requirements, such as 1.00mm, 1.25mm, 1.27mm, 2.00mm, 2.50mm, 2.54mm, etc.

　　The expression of the spacing is the distance between the hole and the center of the hole

　　Safety features: such as UL, CSA, VDE, TUV, CE, etc.

　　The knowledge about the basic performance, classification and basic elements of the connector is shared here. Renhoteic has a complete range of products, low prices, and quality assurance. If you are interested in our products, don't hesitate to place an order! We will certainly not let you down!
