A. The contact piece is the core part of the aviation plug to complete the electrical connection function. Generally, the contact is composed of a male contact piece and a female contact piece, and the electrical connection is completed by the insertion of the female contact piece and the male contact piece.
The male contact is a rigid part, and its shape is cylindrical (round pin), square column (square pin) or flat (insert). The male contacts are generally made of brass and phosphor bronze.
The female contact is the jack, which is the key part of the contact pair. It relies on the elastic structure to elastically deform when it is inserted into the pin to generate elastic force to form close contact with the male contact to complete the connection. There are many types of jack structures, including cylindrical type (splitting, shrinking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, 9-shaped), box-shaped (square jack) And hyperboloid wire spring jacks, etc.;

B. The housing is the outer cover of the aviation plug, which provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment when the plug and socket are inserted, thereby fixing the connector to the device;

C. The insulator is also often referred to as the aviation plug base or insert. Its function is to arrange the contacts according to the required position and spacing, and to ensure the contact between the contacts and the contact between the contacts and the shell. insulating properties. Good insulation, with combined screw at both ends.

D. The tail accessories are divided into structural accessories and installation accessories. Structural accessories such as retaining rings, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories have standard parts and general parts.
