Description
Technical field
The utility model relates to frequency microwave equipment technical field, is specifically related to a kind of fixed structure of radio frequency cable connector.
Background technology
Along with frequency microwave technology is growing, apply wide, the demand of involved coaxial cable connector grows with each passing day.User, when use cable connector, not only have higher requirement to the electric property of connector, and to its reliability, stability also has higher requirement.
Current inner wire, insulator, the fixed form of outer conductor mainly contains:
Barb structure, roll straight burr structure and roll reticulate structure, as shown in Figure 1, Figure 2 and Figure 3, can find out it is all that logical interference fit makes hangnail, straight burr or decorative pattern be deep into dielectric inside structure, reach the object of anti-rotation or play.The shortcoming of barb structure is can only Anti-moving, does not reach the object of anti-rotation; The shortcoming of rolling straight burr structure is can only anti-rotation, does not reach anti-leaping object; Roll reticulate structure both can anti-rotation also can Anti-moving, but stressed limited, time a little more energetically, its anti-rotation and anti-leaping effect just cannot realize.And these three kinds of structures are easily by the impact of part tolerance, insulating dielectric materials stability, reliability is low; Very responsive to temperature shock, poor stability; Electric property is poor, generally uses below 6GHz.
Inner and outer conductor embedding structure, as shown in Figure 4, by opening the mode of punching in the middle of cannelure, outer conductor and insulator in the conductor, and in its hole, groove, filling special epoxide-resin glue of joining, inner wire, insulator, outer conductor after solidification, can be made to become to be integrated.Its shortcoming is: processing is slightly complicated, efficiency of assembling is low, high to operative's level requirement; Due to the impact by epoxy resin serviceability temperature, product serviceability temperature range limited (less than 105 degree); Also there is impact in embedding hole to product radio-frequency leakage in addition, and electric property is poor.
Utility model content
The utility model provides a kind of fixed structure of radio frequency cable connector, to solve the poor reliability that prior art exists, and the problem of the low and electric property difference of stability.
The utility model device solves the technical scheme that its technical problem adopts:
A fixed structure for radio frequency cable connector, comprises inner wire, insulator and outer conductor, and inner wire is column, and left end has blind hole, blind hole section have multiple be shorter than blind hole split groove, arrange hangnail near centre position, hangnail rear end arranges a groove; Insulator is column, and there is open lumen at two ends; Outer conductor left end has external screw thread, and right-hand member has a flange, and there is open lumen at two ends, and left end inner chamber is comparatively large, and the hangnail of corresponding inner wire, outer conductor inner chamber arranges an outside groove.
Above-mentioned inner wire hangnail is tapered, and right-hand member size is greater than left end size.
The hangnail of above-mentioned inner wire arranges two parallel planes, and plane width is identical with left end cylindrical dimensional.
The groove size of the tapered back end of above-mentioned inner wire is less than described inner wire right-hand member size.
The cone-shape barbs of the utility model inner wire ensure that when inner wire is subject to external force, and inner wire and insulator instead can not give birth to displacement, Anti-moving, and cone-shape barbs section has two parallel planes, can effective anti-rotation, for connector provides good reliability; The corresponding inner wire hangnail of outer conductor arranges groove, for the hangnail of inner wire compensates, the standing-wave ratio of connector and decay are reduced, thus ensure that the electric property that connector is good, and inner wire hangnail extruded insulator is to outer conductor groove, insulator and outer conductor can not be subjected to displacement, and reliability is high.

1 inner wire, 2 insulators, 3 outer conductors, 11 hangnails, 31 grooves in figure.
embodiment:
As shown in Figure 5 and Figure 6, a kind of fixed structure of radio frequency cable connector, comprise inner wire 1, insulator 2 and outer conductor 3, inner wire 1 is column, left end has blind hole, blind hole section have multiple be shorter than blind hole split groove, arrange hangnail 11 near centre position, hangnail 11 rear end arranges a groove 31, and inner wire 1 hangnail 11 is tapered, right-hand member size is greater than left end size, the hangnail 11 of inner wire 1 arranges two parallel planes, and plane width is identical with left end cylindrical dimensional, and the groove size of cone-shape barbs 11 rear end of inner wire 1 is less than described inner wire right-hand member size; Insulator 2 is column, and there is open lumen at two ends; Outer conductor 3 left end has external screw thread, and right-hand member has a flange, and there is open lumen at two ends, and left end inner chamber is comparatively large, and the hangnail 11 of corresponding inner wire, outer conductor 3 inner chamber arranges an outside groove 31.
The cone-shape barbs of the utility model inner wire ensure that when inner wire is subject to external force, and inner wire and insulator instead can not give birth to displacement, Anti-moving, and cone-shape barbs section has two parallel planes, can effective anti-rotation, for connector provides good reliability; The corresponding inner wire hangnail of outer conductor arranges groove, for the hangnail of inner wire compensates, the standing-wave ratio of connector and decay are reduced, thus ensure that the electric property that connector is good, and inner wire hangnail extruded insulator is to outer conductor groove, insulator and outer conductor can not be subjected to displacement, and reliability is high.
When the utility model uses, insulator 2 is put in outer conductor 3, makes insulator 2 left side concordant with outer conductor 3 left end inner chamber step surface; Inner wire 1 is loaded in insulator 2, makes inner wire 1 blind hole end face concordant with insulator 2 left side.
