Abstract: This pSMD TACT SWITCHaper introduces the optical connector I have mixed series of one connector design principles， and new mounting plate used in the product design and the use of ANSYS software simulation and optimization， improved product reliability。
Outline
Previous high voltage connector， low connectors and fiber opticHDMI CONNECTOR connectors in electronic equipment is installedUSB CONNECTOR separately， but with the increase of high and low voltage and fiber optic terminal， the space required for installation will become increasingly large， increasingly difficult to maintain and repair 。DC JACK Modern and future war on military electronic equipment proposed miniaturization， integration and modularity requirements， and increasingly demanding， and many parts of foreign advanced weapons systems to achieve an integrated and modular， once a problem， you can use laptop connected to the data detection system on-line weaponry to detect， immediately after the detection of the overall damage to the module replacement， maintenance and repair it3.5mm PHONE JACK particularly convenient， saving maintenance time， battlefield survivability stronger。 In this context， many military electronic equipment components have been integrated， mixed optical connector thus came into being， effectively solve the problem of space for installation and maintenance。
This article is mainly used for the connector to connect electronic countermeasures equipment in the data supply， electrical and optical signalsFPC CONNECTOR， which can not only have a low pressure and high pressureSLIDE SWITCH contacts contacts， also includes a light contact， fiber optic connectors， low voltage connectors and organic combination of high voltage connector。
The main performance requirements
● Rated current: 1A (DC)；
● Contact resistance: ≤ 15mΩ；
● Dielectric withstanding voltage: 10kV (sea level) / 6。5 kV (21000m) (four cores)；
● Leakage current: ≤ 10uA；
● Rated working voltage: 5MICRO USB CONNECTOR。6 (DC four-core) / 0。3 (DC seven core) kV；
● Operating temperature range: -55 ℃ ~ +125 ℃；
● Single mode: 1310/1550nm； single head insertion loss: ≤ 0。3dB； reflection loss: greater than 45dB；
Product Design
Overall product design
The connector is a multi-core fast separation classes。 To prevent mis-insertion， the plug housing and receptacle housing is designed with five keyway structure； rapid separation of the class of multi-core connector and screw sets are staples for fast connection to the rapid separation of uses， five keyway complete the connection by means of positioning， connecting sets the plug connector to the socket connector， using corrugated spring locking mechanism to maintain a constant interface pressure。 In order to achieve the purpose of rapid separation of the plug housing with a connecting sleeve， connecting sleeve bore wall mount design spiral groove helix structure of three equal pitch in the bottom of the bayonet slots are staples through holes， The mating connector can be observed； Accordingly， the surface of the socket housing is designed with three staples， can be screwed to the bottom of the spiral groove， the plug is screwed in place to lock the connector。
As a result of the metal shell， EMI design， high reliability， and low altitude has excellent voltage resistance， according to different needs， arbitrarily adjust the length of the cable， on-site installation， application of more flexible。
Plug connector includes a connector sleeve， shell， soft mounting plate assembly pin， socket assembly comprising the optical fiber and the corresponding contact wire 1。25mm standard connector。 Mounting plate material is silicon rubber， molded by the mold； jack and pin compliance GJB1216， the choice of 20 contacts， using bronze crafted car， two-piece slotted structure， shut after aging， outside Use stainless steel casing for protection。 After the completion of product assembly， for the end use of the silicone rubber adhesive seal to ensure the withstand voltage performance。
The receptacle connector comprising a housing， a mounting plate assembly pin， socket assembly comprising the optical fiber and the corresponding contact wire 1。25mm standard connector。TACT SWITCH Shell material is a thermosetting material DAP， is molded by the mold design and construction of the mounting plate having an insulating section and thePHONE JACK right corner radius normal to the assembly and use are not defect， cracked or broken。 Insulated mounting plate designed so that all contacts are securely fixed to the mounting plate in the insulation。 When assembling the product during use potting silicone rubber for blocking passage gap， ensuring withstand voltage performance。
