H20 Four-hole flange Female Socket Aviation plug

H20 Four-hole flange Female Socket Aviation Plug

What should I pay attention to when using aviation plug? In the early days, the design and quality of aviation pins and plugs were generally not good. Although they were not good, there were still a few outstanding points:

1. The tail of all incoming wires contains fixed wire clips.

All pins and seats are made of high quality phosphor copper sheets and precise equipment.

Three, pin plugs and sockets have locking devices. Can ensure in the violent vibration will not fall off, reliable contact.


When using aviation Waterproof Plug, should pay attention to the following matters:

1, needle type aviation plug Waterproof Connector for living and mobile electrical appliances, the minimum cross-sectional area of the core wire shall not be less than 0.2 square meters, for the production of mobile electrical appliances, shall not be less than 0.5 square meters.

2. The black or yellow-green cores in two or four strands are ground cables and cannot be used to ground wires of other colors. It is not allowed to add a ground wire to two or three strands of goods.

3. The end of the power lead must be firmly pressed into the pin plug. For pin plugs without platen structure, a buckle should be attached to the end so that the connection between the core wire and the Circular Waterproof Connector of the aviation pin plug does not directly bear the tension of the conductor.

4. The insulation layer of each core wire shall be complete and shall not be exposed in the cavity of the pin plug. The core wire end and the wiring terminal must be connected correctly.



The mechanical properties of aviation plug determine the mechanical properties of all kinds of electronic and electrical equipment. When choosing, we should consider how much volume and coverage area, how much stabbing and pulling output of terminals, and how durable.
