Connectors, also known as connectors, mainly provide convenient electrical plug-in connections in electronic products and power equipment, and are widely used in electronic equipment, which greatly improves the production and maintenance efficiency of electronic products. So what is the basic structure of the connector? The following Huijue Network will give you a detailed answer!

The basic structure of the connector:

① Contact piece. It is the core part of the connector to complete the electrical connection function. Generally, the contact pair is composed of an anode contact and a cathode contact, and the electrical connection is completed through the insertion of the female and male contacts. The anode contact is a rigid part, and its shape is cylindrical (round pin), square column (square pin) or flat (blade). Anode contacts are generally made of brass, phosphor bronze.

The cathode contact is the jack, which is the key part of the contact pair. Relying on the elastic structure, the elastic deformation occurs when the pin is inserted, and the elastic force is generated to form a close contact with the positive contact to complete the connection. There are many types of jack structures, such as cylindrical type (splitting, shrinking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, “9” shape), box type (square jack ) and double-sided wire spring jacks, etc.

② insulator. The insulator is also often called a base or a mounting plate. Its function is to arrange the contacts according to the required position and spacing, and to ensure the insulation performance between the contacts and between the contacts and the housing. Good insulation resistance, withstand voltage performance and ease of processing are the basic requirements for selecting insulating materials to be processed into insulators.

③ shell. The shell, also known as the shell (depending on the variety), is the outer cover of the connector. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment when the plug and socket are mated, and then fixes the connector to the on the device.

④Accessories. Accessories are divided into structural accessories and installation accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings and gaskets, etc. Installation accessories such as screws, nuts, screw rods and spring rings, etc. Most of the accessories have standard parts and general parts.
