USB connector is composed of which mechanism

Connectors in real life is everywhere, such as the most common computer USB connectors, cell phone sockets, precision electronic connectors, power connectors, etc., but for the detailed structure of the connector, I believe that many people are not clear, such as the connector is by the free end of the electrical connector (plug), the fixed end of the electrical connector (socket). Socket through its square, disc fixed in the electric components, plugs are generally connected to the cable, through the connection nut to achieve the plug, socket connection.1. Connector contact, is the completion of the core parts of the electrical connection: by the positive contact and negative contact composed of contact pairs, through the yin and yang contact parts of the insertion of the completion of the electrical connection; the positive contact is a rigid part of the shape of the cylindrical (round pins), cylindrical (square pin), or flat (tabs) ) or flat (insert); negative contact parts that is the jack, is the key part of the contact parts, it relies on the elastic structure in the elastic deformation with the pin insertion and fusion of the elastic force and the positive contact parts to form a close contact, to complete the connection. Jack structure of many kinds, there are cylindrical, tuning fork type, cantilever beam type, box-shaped and hyperbolic wire spring jack, etc. 2. connector insulator, also often referred to as the base or mounting plate: its role is to make contact with the required position and spacing, and to ensure that the contact between the contact parts and contact with the shell of the insulation between the performance. Good insulation resistance, voltage resistance, and ease of processing are the basic requirements for selecting insulating materials to be processed into insulators. Insulator material types are many, such as pa6t, LCP, etc. 3. connector shell, also known as the shell, is the connector's outer shell: it provides mechanical protection for the insulated mounting plate and pins inside, and provides the alignment of the plug and socket insertion and closure, and then the connector is fixed to the device. The shell is generally made of aluminum alloy processing (machining, cold extrusion, die casting), and the steel shell is mostly used for glass sealing welding and high temperature resistant electrical connectors.-4、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
