The fixed form that radio frequency coaxial microband connector is conventional is that epoxy resin encapsulated fixed structure is if Figure 1A and annular knurl hangnail fixed structure are as Figure 1B.Epoxy resin encapsulated fixed structure be product inner wire embedding groove, form pin between insulator vertical core and shell vertical core.There is two problems in this structure: first, the serviceability temperature of epoxy resin encapsulated fixed structure product can only reach 105 DEG C, higher than this temperature epoxy resin meeting deliquescing, the adhesion between inner wire and insulator is caused sharply to decline, now the stressed play that is easy to of inner wire even comes off, and causes product failure.The second, when product uses, inner wire welds mutually with module, if welding temperature is too high, or weld time is long, then epoxy resin may soften, high to installation requirement.
In order to improve the serviceability temperature of product, adopt annular knurl hangnail fixed structure as Figure 1B.Annular knurl hangnail fixed structure is inner wire is that annular knurl adds hangnail, and shell is barb structure.Inner wire and insulator and between insulator and shell all by being fixed with pressure.There is two problems in this structure of this structure: the first, and it is more that inner wire annular knurl and hangnail cause inner wire diameter to suddenly change, and causes larger reflection in diameter sudden change place, very large on the impact of product voltage standing wave ratio electrical property.The second, this infrastructure product inner wire fixed end taken about the point of fixation value is little, and in product use procedure, inner wire easily rotates.
How to make radio frequency coaxial microband connector structure fixing reliable, superior electrical property and the technical barrier that miniaturization is the art to be faced.
The utility model project team is on the internet with regard to this theme, and at home and abroad patent documentation and the journal article retrieval published, not yet find the report closely related and the same with the utility model or document.
