Rectangular connectors, known as headers, male pins, and several other types, are useful components used to connect two or more electronic devices to communication and power systems. The 70246-2002 China National Standard for rectangular connectors is an important document that defines their application field and working principle.

The purpose of the 70246-2002 China National Standard is to provide a unified specification promotion and common product identification for all types of rectangular connectors, including cylindrical headers, male pins, and other types used in electronic and telecommunication industry. Contents of this document include definitions of terms, product overview, technical requirements for product safety, environmental protection, and thermal performance, as well as technical details on wiring, lock and other requirements.

The application field of 70246-2002 requires the rectangular connectors for information technology, telecommunications, consumer electronics, component assembling, automotive, industrial automation, aerospace, etc. According to the connectors’ outer size, polar and lines, it can be divided into 2 types: Standard Type and Special Type.

The working principle of 70246-2002 rectangular connectors is mainly based on inserts that are capable of connecting multiple lines simultaneously. With the good performance of multiple horizontal pins connection and bulkhead connection, the rectangular connector of 70246-2002 can be applicable under multiple conditions. The connection will be completed without additional soldering, only need to plug in the two interface, and connection can be reached with good contact and lower mechanical resistance. The contact resistance of 70246-2002 is 100 milliohms, which can meet the application requirements of various products.

To sum up, 70246-2002 rectangular connectors, also known as headers, male pins, and other types, can be widely used in the fields of information technology, telecommunications, consumer electronics, component assembling, automotive, industrial automation, aerospace, etc. with good performance of multiple horizontal pins connection and bulkhead connection. Different types of inserts will have different characteristics, making it possible to meet the needs of different products. 70246-2002 China National Standard for standardizes the application field and working principle of the rectangular connectors.
