The technical solution adopted for the present invention to solve the technical problems is: a kind of high performance precision microwave adapter, comprise shell, insulator, there is the outer conductor of axially extending bore, four insulating trips, contact pin and swivel nut, described contact pin is followed successively by front tab vertically from front to back, canned paragraph, linkage section and rear tab, described insulator is set in described canned paragraph and inwall and described canned paragraph close-fitting, the in the housing nested and front inner wall close-fitting of outer wall and described shell of described insulator, described swivel nut is sheathed to be fixed on the back segment outer wall of described shell, the rear end of described outer conductor has annular boss, the front end of described outer conductor is stretched into from the rear end of described shell described shell and the leading flank of described annular boss leans on the rear end face of described shell, described outer conductor stretches into the outer wall of the part in described shell and described shell close-fitting, described outer conductor offers four draw-in grooves be uniformly distributed circumferentially that notch is positioned at front end face, each described insulating trip is that tile comprises the interlude with curvature and two that are connected as a single entity with the both sides of described interlude respectively perpendicular rectangular flanks, described four insulating trips circumferentially evenly arrange in the housing and the depression direction of described four insulating trips toward the axis of described shell, two adjacent flanks of adjacent two described insulating trips overlap completely and are embedded in a described draw-in groove, the centre position of described linkage section has the contact pin groove of one section of hollow cylinder, described contact pin is nested in the axial passage of four described interludes formation by described contact pin groove.
In order to improve the electric property of described high performance precision microwave adapter further, the rear end of described insulator also has the mis-registry compensation step of the hollow cylinder coaxial with described insulator, and described mis-registry compensation step-shaped top leans against on the front end face of described linkage section.
Concrete, between described swivel nut and described shell, the outer wall of described shell offers the first ring connected in star coaxial with described shell; Corresponding described first ring connected in star, the inwall of described swivel nut offers the second annular groove; Snap ring is provided with, for fixing described swivel nut and shell between described first ring connected in star and the second annular groove.
As preferably, ensure that swivel nut not easily comes off from shell, near described annular boss, between described swivel nut and shell, be also provided with sealing ring.
The invention has the beneficial effects as follows, this high performance precision microwave adaptor structure is novel, volume is little, lightweight, bandwidth, on the basis ensureing sufficient mechanical strength, reduce backing material to obtain less effective dielectric constant as far as possible, thus the operating frequency range of expansion wide-band microwave communication equipment, electric property is good, has good market prospects.
