Harbiy konnektorlarning afzalliklari nimada
Harbiy konnektorlar uskunalar va komponentlar va tizimlar o'rtasida elektr aloqasi va signal uzatishni amalga oshiradi va to'liq tizimni shakllantirish uchun zarur bo'lgan asosiy komponentlardir. Harbiy konnektorlar va boshqa foydalanish uchun ulagichlar o'rtasidagi asosiy farq qattiq ishlab chiqarish toleranslaridir, ya'ni ulagichlar mustahkam bo'lishi uchun qurilgan va yuqori darajadagi qattiq sinovdan o'tishi kerak. Yuqori ishonchlilik va yuqori narx uning ajralib turadigan xususiyatlari hisoblanadi.
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 ulagich
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. Dumaloq ulagich
Dairesel konnektorlar eng ko'p ishlatiladigan harbiy konnektorlardir. Ular oson ishlov berish, turli spetsifikatsiyadagi kabellarga moslashish, mustahkam tuzilish, tez va qulay ulanish xususiyatlariga ega va atrof-muhitga chidamli{0}}turli xil shakllarda loyihalashtirilishi mumkin.
c. Kompozit konnektor
Kompozit konnektor - bu metall qobiqni kompozit qobiq bilan almashtiradigan ulagich. Ulagich kuchli korroziyaga chidamliligi va engil vazniga ega. U aerokosmik tizimlarda keng qo'llaniladi. Mil{0}}c-29600a mahsulotlari dunyoda keng qo'llaniladi. Ikkita standart a va b seriyalari mavjud. A seriyasi mil-c-38999 o'rnatish plitasi teshik tartibini, b seriyali mil-c-81511 o'rnatish plitasi teshik tartibini qabul qiladi. Mil-c-81511 yangi dizayn standarti bo'lganligi va mahsulotlarda ishlatilmaganligi sababli, bir qator ishlanmalar tezda amalga oshirildi.
d. Germetik muhrlangan ulagich
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.
Zamonaviy va kelajakdagi yuqori{0}}texnologik urushlar harbiy elektron jihozlarga tezkor texnik xizmat ko‘rsatish, almashtirish, shaklini o‘zgartirish, yig‘ish samaradorligini oshirish va qurol funksiyalarini tezda tiklash kabi yangi va yuqori talablarni ilgari surdi. Ushbu ehtiyojlarni qondirish uchun modulli konnektorlar va ko'r konnektorlar qurol tizimlarida qo'llaniladi va modulli dizaynlar qurilish bloki yondashuvidan foydalanadi, shu bilan tizimni o'zaro ulash uchun koaksiyal kabeldan foydalanishni kamaytiradi va modulli ko'r RF konnektorlari elektron qarshi choralar uchun keng qabul qilinadi , Fazli qator radar va yuqori{1}}kuchli ko'r RF konnektorlari rivojlanishning yangi yo'nalishidir.
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.
Xulosa qilib aytadigan bo'lsak, elektron axborot sanoatining jadal rivojlanishi va zamonaviy yuqori{0}}texnologik urushda qurol va jihozlarga qo'yiladigan yangi talablar bilan harbiy konnektorlarning rivojlanishi sezilarli o'zgarishlarga duch keldi, ulagichlarni modullashtirish jadallashtirildi. , va harbiy konnektorlar va tijorat konnektorlari Interpenetratsiyaga ega, chegaralar mog'orlanishga moyil va hokazo. Ushbu o'zgarishlar harbiy konnektorlar rivojlanishining eng muhim jihatlari bo'lib, ularning o'zgarishlarining chuqurligi va kengligi diqqatimizni jalb qilishimiz kerak.
