Description
Technical field
The present invention relates to a kind of high speed data connector and its conductor assembly.
Background technology
In general electric connector includes housing and contact, and contact is arranged on housing by insulator, in needs pair
When connector carries out Seal Design, generally use O-ring seal structure is realized between housing and housing, between housing and insulator
And the sealing between insulator and contact.It is existing usually using high-speed differential contact component when connector need to transmit high speed signal
" connector for being used to transmit high-speed differential signal connects some high-speed differential contact components as disclosed in Chinese patent CN201075516Y
Contact element structure ", includes the outer pin of round metal tubular, and multiple be used for and intermateable connector is distributed with around circumferentially-spaced in the front end of outer pin
Contact Elastic Contact spring contact, spring contact is integrally formed with outer pin, and insulator is provided with outer pin, is existed in insulation
On have a pair or interior pin mounting hole that two teams are uniformly distributed along the circumference, interior pin is installed in interior pin mounting hole, interior pin quantity it is more and
Size is smaller, due to the limitation of installation dimension, sealing ring can not be set to seal between interior pin and interior pin mounting hole, and outer pin and interior
Pin needs frequently to plug, therefore outer pin, interior pin need to be by SPECIAL MATERIALs（Such as copper）It is made, and due to such material and glass
Coefficient of expansion difference it is larger, conventional glass sintering technology can not be used directly between interior pin and outer pin, that is to say, that
Generally interior blow-by between pin and insulator and insulator and outer pin when in use, only relies on the O set on the parting surface of housing
Type sealing ring realizes sealing, realizes plug with socket to sealing property overall after slotting connection.The problem of so existing is plug
Need that frequently the abrasion of the O-ring seal of parting surface may be caused, generally this abrasion is not easy to observe to inserting and separating with socket
Judge, when the O-ring seal broken invalid on housing, the sealing function of plug fails simultaneously, and now water will extend over breakage
O-ring seal, by the high-speed differential contact component of non-tight, into inside cable, cause whole piece cable seal to fail.
