How to select a wire to board connector


After so many years of development, the wire to board connector industry has produced various types of connectors. In terms of industry, what are we going to do? We all know that connector is a kind of component that electronic engineering and technical personnel often contact. It makes the current flow and makes the circuit realize the predetermined function. Connector is an indispensable part of electronic equipment. If you observe the current flow path, you will find one or more connector components.

If the general connector is exposed to extreme conditions, its performance and reliability will be greatly reduced. Therefore, a new connector is born. It is specially designed for connector components that need to be used in harsh environment. It is more robust and more resistant than general connectors. This new connector interface is called industrial connector. So how to choose this type of connector?

First, environmental requirements

Different environmental conditions, the location of the connector determines the difference of temperature and humidity, so we should consider the location and the expected environmental conditions. What is the applicable period and information of other relevant storage conditions. Requirements for impact and vibration, including transportation requirements and production environmental conditions, should also be included in the environmental notes. The connector manufacturer states that the area where the highest temperature is generated is around the converging continuous current that is guided by the connector.

Second, mechanical performance requirements

What is the difference between the size of the connector and the pull-out capacity, and what is the difference between the size of the connector and the size of the connector.

Third, connector type

What the connector is to be connected to and what it is mainly used in, etc. these issues are the priority, which determines the type of connector selected. The location where the connector is used will directly affect whether to enhance its sealing performance or to add a shielding shell outside the insulation body. The type of connector also determines which terminals to use and how many conductive terminals to arrange. Of course, this also involves some terminal technology reference.

Fourth, electrical requirements

When we choose electrical connector, we should also consider the electrical requirements of the product. What kind of voltage and current requirements of the product, whether the connector can be well applied in such electrical properties, these issues about electrical requirements need us to consider. In addition, we also need to consider some other electrical conditions: resistance, allowable resistance variation, MV drop, maximum current value, maximum voltage value, inrush current value, characteristic impedance, insertion loss and EMI shielding efficiency.
