CUPLA COAXIALA DE CONEXIUNE

摘要

This invention relates to a simple, field installable, low cost, miniature, push-pull, quick connect/disconnect electrical connector system having a VSWR (voltage standing wave ratio) of less than 1.35 for all signal frequencies from 0.1 to 6 GHz useful for interconnecting coaxial cables having a characteristic impedance in the range of 50 ohms. The connector system is made up of a plug member and a jack member each comprising but three basic parts. The first part of each member is comprised of an integral tubular member of relatively soft electrically conductive material. The second part of each member is in turn comprised of a dielectric insert which is held in its respective tubular member by staking or rolling a reduced section of its tubular member's wall. The front portion of the jack member fits into the front portion of the plug member and through the action of an internal shoulder within the plug member a predetermined spacing between the dielectric inserts held by the plug and jack members is established when the members are fully mated. Each dielectric insert is in turn bored to receive one of two matable pin-like electrical contacts each of which comprises the third part of its respective connector member. Each contact has a hollow rear portion which may be crimped to the center conductor of a respective coaxial cable and thereafter inserted into the bore of its respective insert and retained therein. The outer conductor of each coaxial cable may be crimped around a reduced section of the rear portion of each connector by means of a crimping ferrule. The aforesaid fixed spacing between the dielectric inserts acts to produce a high impedance relative to the impedance afforded by the dielectric inserts to effect the afore-referenced VSWR of less than 1.35 for signal frequencies between 0.1 and 6 GHz.
