What are aviation plugs? What are the basic components of aviation plugs? Now let’s learn together:

The basic structural parts of aviation plugs: 1 contact pieces; 2 insulators; 3 outer shells (depending on the different type); 4 accessories.

1. Contacts are the core parts of the aviation plug to complete the electrical connection. A contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed through the engagement of male and female contacts.

The male contact is a rigid part and its shape is cylindrical (round pin), square (square pin) or flat (insert). The male contacts are typically made of brass, phosphor bronze.

The female contact , the jack, is the key part of the contact . It relies on the elastic structure to be elastically deformed when inserted with the pin to generate elastic force to form a close contact with the positive contact to complete the connection. There are many types of jacks, including cylinder type (grooves, necks), tuning fork type, cantilever beam type (longitudinal grooving), folding type (longitudinal grooving, 9-character), box shape (square hole) as well as hyperbolic wire spring jacks.

 

2. Insulators are alsonamed as bases or inserts. Their function is to align the contacts according to the desired position and spacing, and to ensure the insulation performance between the contacts and the housing. Good insulation resistance, withstand voltage performance, and ease of processing are basic requirements for the selection of insulating materials to be processed into insulators.

 

3. The housing, also called the shell, is the outer cover of the aviation plug. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides the alignment of the plug and socketwhen connecting, which fixes the aviation plug to the equipment.

 

4. Attachments include structural accessories and mounting accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Install accessories such as screws, nuts, coils, etc. Most accessories have standard parts and common parts.
