What are the advantages of military connectors?

ONE. What are the advantages of military connectors? Military connectors make electrical connections and transmit signals between equipment and components and systems, and are an essential basic component of a complete system. The main difference between military connectors and connectors for other applications is the tight manufacturing tolerances, which means that the connectors are ruggedized and must undergo rigorous testing. High reliability and high cost are its distinguishing features. Military connectors mainly include circular, rectangular, printed circuit, RF connectors, special type and so on, which is an important engine to drive the development of the whole connector industry, and occupies an important position in the international connector market. a. Nano connectors As analog circuits give way to digital circuits, the whole device is shifted from desktop to portable, and the chip size of the circuits becomes quite small, which requires smaller operating currents and smaller wires and connectors, thus requiring smaller dimensions and less weight. Among some of the requirements is the growing need for durability. This trend has led to the emergence of nano-based connectors. Nano Corporation of America is a major developer of nano connectors. Nano connectors do not currently have a military specification and were developed under the guidance of MIL-C-83513, which was used to test for durability and reliability. However, the nano connector is much higher than MIL-C-83513, with an upper operating temperature of over 125°C and a center distance of 0.635 mm (0.025 in.), which is only 1.25 of that specified in MIL-C-83513. The insulation is a glass-containing LCP liquid crystal polymer, which provides a high degree of insulation. The hole arrangement of the insulation mounting plate between pins is only 0.254 mm ~ 0.28 mm (10 mils ~ 11 mils). Light weight. Compared to the equivalent weight of a miniature D-type connector (2.6 g), the 21-bit nano connector weighs only 0.4 g. It also has high durability and can withstand vibrations and shocks in excess of 10,000 Gg during rocket ignition and launch. Nano connectors have been proven in military and aerospace applications and have expanded into the oil and medical industries and will replace micro connectors in new designs. The transition from micron to nano is known abroad as "a revolution in connector technology". b. Circular connector circular connector is the most widely used military connectors, with easy processing, adapt to various specifications of the cable, sturdy structure, quick and easy to connect, and can be designed into a variety of environmentally friendly forms and so on. c. Composite connectors Composite connector is a composite shell instead of a metal shell connector. The connector is corrosion resistant and light weight. It is widely used in aerospace systems. mil-c-29600a products are widely used in the world and are standardized in two series, a and b. The a series utilizes the mil-c-38999 mounting plate hole arrangement, and the b series utilizes the mil-c-81511 mounting plate hole arrangement. Since mil-c-81511 belongs to the new design standard, not used in the product, therefore, a series of rapid development. d. Gas-tight connectors for military and aerospace applications is a bigger change is the so-called "gas-tight evolution". Instead of inserting a module, the military is now considering treating the entire board as a component. A future adjustment is how to seal the insert with a connector. nanonics has developed a nano-type hermetic connector that is soldered to the wall by a laser beam through a hole in a sealed box containing the circuit board, thus creating a removable module. In this way, the nano-type connector is not a stand-alone component, but is integrated into the module. A flat, customized circuit in the module can occupy any area and can process all the electronic signals needed for Patriot missile guidance. The sealed individual modules are only part of the multifunctional component architecture.
