Due to its very high quality and reliability, circular electrical connectors are widely used in aerospace and defense systems. So do you know the structural characteristics and functions of circular electrical connectors? In order to adapt to the high temperature resistance, low temperature resistance and flame retardant of the product, the geometric dimensions of the parts are guaranteed to be stable and reliable. Insulators are mostly molded from thermoset plastics. The interface sealing body and the wire sealing body are formed by silicone rubber molding. Contact body - pin jack is the general term for contact body, which is divided into welding type, crimping type and wrapping type, etc., used to realize circuit connection. The pin jack is the key component of the electrical connector of the electronic connector, which directly affects the reliability of the electrical connector. Most of the pin jacks are made of elastic copper alloy material with good electrical conductivity, and the surface is silver-plated and gold-plated to achieve the purpose of low contact resistance and corrosion resistance. Structural features are: environment resistance, bayonet connection, multi-key position, contact body and wire crimp connection failure. The shell and the shielding ring ensure the electromagnetic interference shielding ability. In various electronic systems of weapons and equipment, electrical connectors perform electrical connection and signal transmission between devices and devices, components and components, and systems and systems, and are the basic components necessary to form a complete system. In various military aircraft and weapon equipment, the amount of electrical connectors is relatively large, especially the amount of electrical connectors used in aircraft is very large. Generally speaking, the usage of an aircraft electrical connector can reach hundreds to thousands, involving tens of thousands of lines. Therefore, in addition to meeting the general performance requirements, the electrical connector must meet the requirements of good contact, reliable operation, and convenient maintenance. The reliability of its operation directly affects the normal operation of the aircraft circuit, involving the entire main engine. safety. For this reason, the host circuit has very strict requirements on the quality and reliability of the electrical connector. It is precisely because of the high quality and high reliability of the electrical connector that it is also widely used in military systems such as aviation, aerospace, and national defense.
