WHAT ARE THE SAFETY PARAMETERS OF AVIATION PLUGS?

Aviation plugs are a type of connector that originated from the military industry. The aviation plug is an electromechanical component connected to the electrical circuit, so its own electrical parameters are the first consideration when choosing an aviation plug. The correct selection and use of aviation plugs is an important aspect of circuit reliability. Below we mainly introduce the safety parameters of aviation plugs.

 

The safety parameters aviation plug

1.Insulation resistance

Insulation resistance refers to the resistance value that appears when a voltage is applied to the insulation part of an aviation plug, so that a leakage current is generated in or on the surface of the insulation part. It is mainly affected by factors such as insulation materials, temperature, humidity, and fouling.

The insulation resistance values provided in the aviation plug samples are generally the index values under standard atmospheric conditions. Under certain environmental conditions, the insulation resistance value will be reduced to an unnecessary degree. Also pay attention to the test voltage value of the insulation resistance.

 

2. Withstand voltage

Withstand voltage is between the insulated parts of the contact pair or between the insulated part and the ground.The threshold voltage that can withstand higher than the rated voltage within a specified time without causing breakdown. It is mainly affected by contact distance and creepage distance and geometry, insulator materials, ambient temperature and humidity, and atmospheric pressure.

 

3.Flammability

No aviation plug is inseparable from electric current during operation, which poses the danger of fire. Therefore, the aviation plug is required not only to prevent ignition, but also to self-extinguish in a short time when it ignites and catches fire. Pay attention to select aviation plugs with flame-retardant and self-extinguishing insulation materials.

 

4. Mechanical life

The mechanical life of the aviation plug refers to the plug life, which is usually specified as 500 to 1000 times. When the specified mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the aviation plug should not exceed the specified values.

 

5. Installation method

The aeronautical plug is installed with front and rear installation. The installation and fixing methods include rivets, screws, or quick locking of the aeronautical plug itself. There is also a plug and socket that are both free-end aviation plugs.

 

6. Environmental parameters

Environmental parameters include environmental temperature, humidity, sudden temperature changes, atmospheric pressure, and corrosive environments. The environment in which the electrical connector is used, stored and transported has a significant impact on its performance, so the corresponding aviation plug must be selected according to the actual environmental conditions.

 

7. Ambient temperature

The metal material and insulation material of the aviation plug determine the working ambient temperature of the electrical connector. High temperature will damage the edge material, causing the insulation resistance and voltage resistance to decrease; for metals, high temperature can cause the contact pair to lose its elasticity, accelerate oxidation and cause plating deterioration. The general ambient temperature is -55 ~ 100 ℃, which may be higher in special occasions.
