Or directly replace the inner conductor and dielectric support of the connector with the inner core of the cable and the insulating layer of the cable. The characteristic of these two structures is that the polytetrafluoroethylene dielectric is completely filled between the inner and outer conductors of the connector, which cannot achieve precision N-type connectors. requirements

Abstract

The invention discloses an N-type connector, which includes a first outer conductor, a dielectric body and an inner conductor. The first outer conductor includes a mating end connected with an external plug and a tail end used for being fixedly connected with a radio frequency cable. The dielectric body is arranged in the first outer conductor and has multiple through holes. The inner conductor iscomposed of a first inner conductor, a second inner conductor and a third inner conductor. The second inner conductor passes through the dielectric body, and the two ends of the second inner conductor are located outside the dielectric body. The first inner conductor and the third inner conductor are respectively connected with the two ends of the second inner conductor. Impedance compensation iscarried out by means of coplanar compensation, which can reduce the loss caused by dielectric filling. Meanwhile, the N-type connector has good voltage standing wave ratio, and meets the requirementsof precision N-type connectors.

Description

technical field [0001] The invention relates to the technical field of radio frequency connectors. More specifically, it relates to an N-type precision connector. Background technique [0002] N-type radio frequency coaxial connector is a kind of radio frequency connector with threaded connection mechanism. It has the characteristics of wide frequency band, good shock resistance and high reliability. It is widely used in microwave communication and measurement systems. N-type cable connectors are usually composed of inner conductors, outer conductors, insulation supports, sleeves for welding cable shielding layers, lock nuts and other parts. [0003] In the existing technical solutions, the inner conductor of the N-type connector is usually welded to the cable core wire, and the inner conductor is fixed in the coaxial cavity by using a polytetrafluoroethylene medium. Or directly replace the inner conductor and dielectric support of the connector with the inner core of the ...
