What is an aviation plug? What are the basic structural components of aviation plugs? Let's learn together:

 

The basic structural components of aviation plugs include ① contact parts; ② Insulator; ③ Shell (depending on variety); ④ enclosure.

 

1. Contacts are the core components of aviation plugs that perform electrical connection functions. Generally, a contact pair is composed of a positive contact and a negative contact, and the electrical connection is completed through the insertion and connection of the negative and positive contacts.

 

The positive contact part is a rigid part, and its shape is cylindrical (circular pin), square cylindrical (square pin), or flat (insert). Positive contacts are generally made of brass and phosphor bronze.

 

The female contact piece, also known as the socket, is a key component of the contact pair. It relies on the elastic structure to undergo elastic deformation when it is inserted into the contact pin, generating elastic force and forming close contact with the male contact piece to complete the connection. There are many types of jack structures, including cylindrical (slotted, necked), tuning fork, cantilever beam (longitudinal slotted), folded (longitudinal slotted, 9-shaped), box (square) and hyperboloid linear spring jacks.

 

2. Insulator, also known as a base or insert, is used to arrange the contacts in the required positions and spacing, and to ensure the insulation performance between the contacts and between the contacts and the shell. Good insulation resistance, voltage resistance, and ease of processing are the basic requirements for selecting insulation materials for processing into insulators.

 

3. The shell, also known as the shell, is the outer cover of an aviation plug. It provides mechanical protection for the insulated mounting plate and pins inside, and provides alignment when the plug and socket are inserted, thereby fixing the aviation plug to the equipment.

 

4. The attachments are divided into structural attachments and installation attachments. Structural accessories such as snap rings, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Install accessories such as screws, nuts, screws, spring coils, etc. Most attachments have standard and universal parts.
