Importance of the individual structures of rectangular electrical connectors

Rectangular electrical connector in addition to the general performance requirements, but also requires the electrical connector to meet the functional requirements of good contact, reliable operation and easy maintenance. So what is the structure of the military rectangular electrical connector like? Rectangular electrical connector structure consists of fixed-end rectangular electrical connector and free-end rectangular electrical connector. The basic structural components of the connector are ① contact parts; ② insulator; ③ shell (depending on the species); ④ accessories. So what is their respective roles? The following Huicheng yuan electronic connectors to explain:1. Contacts are military rectangular electrical connectors to complete the electrical connection function of the important parts. Usually, the contact pair consists of male and female contacts, and through the insertion of female and male contacts to complete the electrical connection. The male contact is a rigid part, and its shape is cylindrical (round pin), square cylindrical (square pin) or flat. Male contacts are usually made of brass and phosphor bronze. The female contact, or jack, is the critical part of the contact pair. It relies on the elastic structure to generate elasticity from the elastic deformation of the pin when it is inserted to form a tight contact with the male contact and complete the connection. There are many kinds of military rectangular electrical connector jacks, cylindrical (slotted, constricted), tuning fork, cantilevered (longitudinal slotted), folding (longitudinal slotted, 9-shaped), box type (square jacks), hyperbolic steel wire spring jacks. 2. insulator The insulator is also often referred to as the base or mounting plate. Its role is to arrange the contacts in accordance with the required position and spacing to ensure that the insulation between the contacts and between the contacts and the shell. Good insulation resistance, voltage resistance and processability are the basic requirements for selecting insulating materials to be processed into insulators.3. Shell The shell of the military rectangular electrical connector. It provides mechanical protection for the built-in insulated mounting plate and pins, and provides alignment when plugs and sockets are inserted, thus securing the connector to the device.4. Fittings are divided into structural fittings and mounting fittings. Accessories such as circlips, locating keys, locating pins, guide pins, coupling rings, cable clamps, seals, and gaskets. Installation accessories, such as screws, nuts, screws, spring rings and so on. Most of the accessories are available in standard and common parts.
