Summary of the invention
What the present invention proposed is a kind of high density circular optical connector developed based on the III series electric connector housing of GJB599A-1993 " quick separating of resistance to environment high density small round electric connector generic specification ", its object be intended to design a can meet to machinery and climatic environment is higher, reliability high field optical connector, multicore light path interface channel can be reliably provided, light path for environmental requirement higher (as high/low temperature, anti-vibration), high reliability place connects, as places such as aircraft, locomotive and naval vessels.
Technical solution of the present invention: the III series electric connector housing of its housing application GJB599A-1993 " quick separating of resistance to environment high density small round electric connector generic specification ", realizes the connection of light path by designing corresponding contact pin component and base construction.On electric connector housing, pedestal, seal are carried out bonding assembling by epoxy glue or silicon rubber; When socket and plug docks, after housing key mapping is aimed at, plug imports with socket and is connected by pilot pin, the ceramic insertion core top of the contact pin component of plug and socket can in the ceramic oversleeve of ceramic oversleeve array Contact, and along with plug swivel nut screwing operations, the ceramic contact pin of contact pin component can retreat by Compress Spring, for ceramic end face provides reliable exact contact, realizes reliable light path and connects.
Good effect of the present invention:
1) apply the III series electric connector housing of GJB599A-1993 " quick separating of resistance to environment high density small round electric connector generic specification ", after selection suitable material, connector can meet high/low temperature and three climatic environments such as anti-;
2) by the selection of key mapping, the situation of attachment unit interface wrong can be avoided;
3) realize multicore to connect, the mechanical environment requirements such as anti-vibration, resistance to mechanical impact and restrain acceleration can be met;
4) by the application of pilot pin, guide effect when plug and socket connects can not only be realized, and the shock resistance of connector can be increased;
5) after ceramic oversleeve damages, by changing ceramic oversleeve array, the maintenance to product can be realized fast;
6) the highlyest assemble 32 cores, realize 32 tunnel optical signal transmission.
