Millised on sõjaliste pistikute eelised?
Sõjalised pistikud teostavad elektriühendust ja signaaliedastust seadmete ning komponentide ja süsteemide vahel ning on vajalikud põhikomponendid tervikliku süsteemi moodustamiseks. Peamine erinevus sõjaliste pistikute ja muuks kasutuseks mõeldud pistikute vahel on ranged tootmistolerantsid, mis tähendab, et pistikud on konstrueeritud nii, et need oleksid vastupidavad ja peavad läbima kõrgetasemelise range testimise. Selle eristavad omadused on kõrge töökindlus ja kõrge hind.
Military connectors mainly include circular, rectangular, printed circuits, RF connectors, special types, etc., which are an important engine driving the development of the entire connector industry and occupy an important position in the international connector market. So what are the new highlights of military connectors? Let's take a look!
a. Nano pistik
As analog circuits give way to digital circuits and entire devices move from benchtop to portable, the chip size of the circuit becomes considerably smaller, requiring less operating current, smaller wires and connectors, thus requiring smaller size and smaller weight. In some requirements, the requirements for durability are getting higher and higher. Under this trend, nano{{0}}type connectors came into being. American Nano is a major developer of nano connectors. Nanoconnectors currently do not have a military specification and were developed under the guidance of MIL-C-83513, which is used to test durability and reliability. But the nano connector is much higher than MIL-C-83513, the operating temperature on it exceeds 125 degree , and the center distance is 0.635 mm (0.025 inches), which is only 1.25 specified by MIL-C-83513. The insulating material is a glass-containing LCP liquid crystal polymer with high insulating properties. The hole arrangement of the insulating mounting plate between the pins is only 0.254 mm to 0.28 mm (10 mil to 11 mil). Lightweight. Compared to the equivalent weight of a miniature D-type connector (2.6g), the 21-bit nano-type connector weighs only 0.4g and is also highly durable, able to withstand more than 10,000Gg of vibration and shock during rocket ignition and launch. Nanoconnectors have been proven in military and aerospace applications, and have expanded into the petroleum and medical industries, and will replace microconnectors in new designs. The transition from micron to nanometer is called "a revolution in connector technology" in foreign countries.
b. Ringikujuline pistik
Ringikujulised pistikud on kõige laialdasemalt kasutatavad sõjalised pistikud. Neil on lihtne töödeldavus, kohandatavus erinevate spetsifikatsioonidega kaablitega, kindel struktuur, kiire ja mugav ühendus ning neid saab kujundada mitmesugustes keskkonnakindlates vormides.
c. Komposiitpistik
Komposiitpistik on pistik, mis asendab metallkesta komposiitkestaga. Pistikul on tugev korrosioonikindlus ja kerge kaal. Seda kasutatakse laialdaselt kosmosesüsteemides. Mil-c-29600a tooteid kasutatakse maailmas laialdaselt. Standardseeriaid a ja b on kaks. A-seeria puhul on kasutusel mil{4}}c-38999 kinnitusplaadi avade paigutus ja b-seeria puhul mil-c-81511 paigaldusplaadi avade paigutus. Kuna mil-c-81511 on uus disainistandard ja seda toodetes ei kasutata, tehti kiiresti rida arendusi.
d. Hermeetiliselt suletud pistik
The biggest change in military and aerospace applications is the so-called "hermeticity evolution". Instead of plugging in modules, the military is now considering treating the entire board as a component. A future adjustment to be made is how the insert is sealed with the connector. Nanonics has developed a nanoscale hermetic connector that is welded to the wall by a laser beam through a hole in a sealed box containing the circuit board, creating a removable module. In this way, the nano-connector is not a separate component, but is integrated in the module. A flat custom circuit in the module can occupy any area and can handle all the electronic signals needed for Patriot missile guidance. The sealed individual modules are only part of the multifunctional component structure.
Kaasaegne ja tulevane kõrgtehnoloogiline{0}}sõda on seadnud sõjalisele elektroonikavarustusele uued ja kõrgemad nõuded, nagu kiire hooldus, asendamine, kuju muutmine, parem kooste efektiivsus ja relva funktsioonide kiire taastamine. Nende vajaduste rahuldamiseks kasutatakse relvasüsteemides modulaarseid pistikuid ja pimeühendusi ning moodulkonstruktsioonides kasutatakse ehitusplokkide lähenemisviisi, vähendades seeläbi koaksiaalkaabli kasutamist süsteemide omavaheliseks ühendamiseks ning modulaarsed pimedad RF-pistikud on elektrooniliste vastumeetmete jaoks laialdaselt aktsepteeritud. radar ja suure-võimsusega pimedad RF-pistikud on uus arengusuund.
At present, a striking development trend of the foreign military connector market is that the boundaries between military connectors and commercial connectors are rapidly blurring. The American Teradyne company believes that "the era of pure military-grade connectors is coming to an end." The main factor leading to this phenomenon is cost, followed by density, and then speed. ".The military is always looking for low-cost solutions, an important approach is to retrofit existing commercial connectors. For example, for special connector mounting boards with 100Ω differential signals and controllable impedance, realistic design challenges is to build a connector that will work reliably in harsh military conditions. This type of connector is readily available in the commercial field but has poor performance and is therefore not made for military avionics systems. Military manufacturers are trying to bridge this gap , In the design of this new differential signal mounting board, other insulating mounting boards that may be digital, RF, power or optical signals are integrated.
Kokkuvõtteks võib öelda, et seoses elektroonilise teabetööstuse kiire arenguga ning uute nõuetega relvadele ja varustusele kaasaegses kõrgtehnoloogilises{0}}sõjas on sõjaliste pistikute väljatöötamine teinud läbi olulisi muutusi, pistikute modulariseerimine on kiirenenud. , ning sõjalistel ja kaubanduslikel pistikutel on interpenetratsioon, piirded kipuvad hallitama ja nii edasi. Need muudatused on sõjaliste ühenduste arendamise tipphetked ning nende muudatuste sügavus ja laius väärivad meie tähelepanu.
