Four basic components of waterproof usb connector

First, the connector contact connector contact is the connector to complete the electrical connection function is indispensable parts. Generally by the positive and negative contacts composed of contact pairs, through the insertion of negative and positive contacts to complete the electrical connection.1. Positive contacts for the rigid parts, the shape of the cylindrical (round pin), cylindrical (square) or flat (insert). Positive contact parts are generally made of brass, phosphorus copper. For example, Weixinlian production of 0.8 side-plug board-to-board connector contact parts using phosphor bronze. 2. Negative contact parts are inserted into the hole, is an important part of the contact pairs, through the elastic structure and the insertion of elastic deformation occurs when the elastic force of the positive contact with the tight contact, to complete the connection. Insert holes have many types of structure, there are cylinder type (slot, shrinkage mouth), tuning fork type, cantilever beam type (longitudinal groove), folding type (longitudinal groove, 9 type), box type (square holes), hyperbolic wire reed jacks, and so on. Second, the connector insulator connector insulator is also known as the base or mounting plate, its role is to make contact with the required location and spacing, to ensure that the insulation between the contact parts and contact parts and the shell. Good insulation resistance, anti-voltage properties and ease of processing is the basic requirements for selecting insulating materials to be processed into insulators. There are many types of insulator materials, such as pa6t, LCP and so on.

Third, the connector shell connector shell, also known as the shell, is the shell of the connector, for the renovation of the insulation mounting plate and pins to provide mechanical protection, to provide plugs and sockets inserted in the alignment, the connector is fixed on the equipment. Shell is usually made of aluminum alloy processing (machining, cold extrusion, die-casting), steel shell is mostly used for glass welding and high temperature resistant electrical connectors. Fourth, the connector's accessories connector accessories are divided into structural accessories and installation accessories, structural accessories such as chucks, locating keys, locating pins, guide pins, connecting rings, cable clamps, seals, gaskets and so on. Installation accessories such as screws, nuts, screws, spring rings and so on. Most of the accessories have standard parts and common parts.
