H16 female welded Aviation Plug

What are the basic functions of an aviation plug? Aviation waterproof plugs on the market today are mainly divided into three types according to their functions, which are mechanical function, electrical function and environmental function. Correct selection and use of aviation plug Waterproof Connector is an important aspect to ensure circuit reliability. Different types of aviation plug its action mechanism is completely different, the use of nature is different.

Mechanical function

Mechanical function Main From the point of view of function, in the course of practical application, the most important is the mechanical function of the plug. The more important principle is the pulling force, which is mainly divided into two types, thrust force and pulling force, also known as pulling force. The requirements are different between the two pulls. What we look for most is maximum thrust.

The piercing force should not be too large, which is generally required to be low, and the separate force should not be too small, otherwise it may affect the reliability of contact. We are involved in the use of the mechanical life, the first is to say the durability of the equipment policy, also known as mechanical operation in the world. Simply put, it takes a stab and a pull as a cycle, and whether it plays a connecting function is judged according to it.

Introduction to aviation Waterproof Plug
The technical performance of this waterproof connector complies with TIA/EIA 568, MIL, IEC, CNS and other standards.Spring snap-in design, tightly locked and buttoned, safe and firm, anti-vibration and impact-resistant.With a zinc alloy shell, the Circular Waterproof Connector has complete electromagnetic and radio frequency interference protection.Gold-plated contacts, high-strength corrosion resistance and electrical conductivity, effectively cope with changes in temperature rise caused by current.The installation method of the socket and the panel is square plate flange installation, the termination of the contact parts and the wire is welded, and the number of contact parts is (2-9).
