Outline standard of aviation plug

·Structural dimension of aviation plug: the overall dimension of connector is very important. There are certain space restrictions for interconnection in products, especially the connector on single board, which cannot interfere with other parts. Select the appropriate installation method according to the use space and installation position. The connector has front installation and rear installation, and the fixing methods include screws, circlips, rivets or quick locking of the connector itself. At the same time, the shape of the connector is divided into straight, curved, T-shaped, round and square;

 

·Shielding material: with the development of communication products, EMC is paid more and more attention. When selecting aviation plug, there needs to be a metal shell, and the cable needs to have a shielding layer. The shielding layer should be connected with the metal shell of the connector to achieve the shielding effect. Injection molding can also be used to wrap the plug with copper sheet, and the shielding layer of the cable and copper sheet are welded together;

 

·Reliability of aviation plug connector: the connector is used to connect signals, so the connection part should be reliable (for example, surface contact is better than point contact, pinhole type is better than leaf spring type, etc.)

 

Characteristic standard / functional specification of aviation plug

·Impedance matching: some signals have impedance requirements, especially RF signals, which are more strict on impedance matching. When the impedance is mismatched, it will cause signal reflection and affect signal transmission. General signal transmission has no special requirements for the impedance of the connector;

 

·Anti misinsertion function: there are two aspects to prevent misinsertion: on the one hand, the aviation plug itself, the connector itself rotates 180 degrees, and the wrong connection leads to the wrong connection of the signal. At this time, it is necessary to choose the anti misinsertion connector as much as possible, or make the assembly unique by adjusting the relative position relationship of the connector; On the other hand, in order to reduce the types of materials, several signals adopt the same connector. At this time, plug a may be inserted into plug B. at this time, it should be noted that if such a situation will cause serious consequences, interfaces a and B must be selected as different types of sockets;

 

·Connectors are required to be used in cold, humid and outdoor environments, such as high temperature and mold;

 

·Aviation plug locking function: in order to prevent the connector from falling off during matching and ensure good contact, the connector needs to have locking function;

 

·Plugging frequency of aviation plug

 

Manufacturer and supplier of aviation plug

·Universality of aviation plug: in the process of connector selection, we should choose common objects as much as possible, especially among products of the same series. The selection of connector has strong universality, reducing material types, increasing quantity, reducing cost and reducing supply risk at the same time;

 

·Cost of aviation plug: cost is also an important factor in the selection process. With the increasingly fierce market competition, the appropriate selection of connector, the cost of connector and processing cost need to be comprehensively considered;

 

·Supply of aviation plugs: the supply of connectors will be affected by many factors. The supply of universal connectors is better than that of non universal connectors;

 

·The aviation plug can better reflect its environmental performance in the design of external materials. Because the external environment is extremely complex, adapting to these complex environments can ensure the exertion of its service performance. Otherwise, it will not only not work well, but also may be dangerous. At present, there are many harsh environments, and there are many types of special connectors for harsh environments, which are common in connector design. They can be selected according to actual needs. Among them, finished products are available for selection in high temperature, high humidity, corrosion and salt resistant environments;

 

·Because the main quality of connectors is inside, especially the internal lines, which cannot be distinguished by ordinary observation, excellent brands and workmanship should be selected when purchasing.

 

The production process of aviation plug and connector is more and more specialized, with more scientific and technological elements. It will also be more suitable for the market, carry out diversified and humanized research and development, and meet the requirements of more environmental standards.
