The basic structural parts of the connector include contacts, insulators, housing (depending on variety), and accessories. The composition of the connector will be described in detail below.
The contact is the core part of the connector and can complete the electrical connection function. Generally, the contact pair is composed of positive contact and negative contact, and the electrical connection is completed by inserting a female contact and a male contact.
The positive contact is a rigid part, and its shape is cylindrical (round pin), square column (square pin), or flat (plug). Positive contacts are usually made of brass and phosphor bronze.
The basic performance of the connector and the elasticity of its basic structure form close contact with the male contact to complete the connection. There are many types of jack structures, such as cylindrical type (slotted and narrowed), tuning fork type, cantilever beam (longitudinal slot), folding type (longitudinal slot, 9 shapes), box shape (square jack) and hyperboloid spring jack Wait.
The basic performance of the connector and its basic structure arrangement position and spacing, and to ensure the insulation performance between the contact parts and between the contact parts and the housing. Good insulation resistance, voltage resistance, and easy processing are the basic requirements for selecting insulating materials for processing into insulators.
The shell is also called the shell, it is the shell of the connector. It provides mechanical protection for the built-in insulating mounting plate and pins, and aligns after the plug and socket are paired, and then fixes the device to the device.
The attachments include structural attachments and installation attachments. Structural accessories such as snap rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Install accessories such as screws, nuts, screws, spring coils, etc. Most accessories have standard parts and universal parts.
