The inventor has analyzed available solid outer conductor coaxial connector and has recognized the connection of screw thread one, manual enlarging installation procedure and the shortcoming of coaxial connector design of curling/compress.For example the whole by reference current unsettled name of submitting on November 5th, 2008 that is included in this that has of the inventor is called that disclosed insertion coupling coaxial connector comprises the multinomial obvious improvement to the coaxial connector technology among the novel application No.12/264932 of u. s. utility of " Insertion Coupling Coaxial Connector ", thereby the conductor end clamping connector no longer need carry out manual enlarging and/or use high moment will be coupled nut driving in connector body in the process of cut cable interconnection outer conductor outside.Similarly,, the whole by reference current unsettled name of submitting on November 2nd, 2009 that is included in this that the inventor has discloses in being called the novel application No.12/611095 of u. s. utility of " Insertion Coupling Coaxial Connector " inserting the multinomial improvement of coupling coaxial connector.
The inventor's the analysis to the electrical property of existing insertion coupling coaxial connector has realized that the tolerance of the vary in diameter of considering the outer conductor contact element that in interconnection process, inserts coupled connector, can not provide whole circumference to connect around outer conductor.Thereby significant RF reveals and can produce through the gap that grasps in the ring in the spring contacts and/or that be applied on the coaxial cable outer conductor outer diameter part, and the RF leakage finally gives off from the gap between the outer conductor of holding ring and coaxial cable.Along with the operating frequency of the signal that transmits along coaxial cable towards higher microwave frequency increase and shorter and shorter wavelength can pass/reveal through with the more and more littler gap of the coaxial connector of the outer conductor interconnection of coaxial cable, the RF leakage becomes especially obvious.
Shown in first exemplary embodiment among Fig. 1-3, coaxial connector 1 has the connector body 3 of Belt connector main hole 5.The insulator 7 that is positioned at connector body hole 5 supports the contact 9 coaxial with connector body hole 5.Coaxial connector 1 is via being arranged in the outer conductor 11 of coaxial cable 13 that the grip surface 17 that grasps on ring 19 the inside diameter mechanically keeps being inserted into the cut cable 15 in connector body hole 5.The spring contacts 21 that is positioned at connector body hole 5 forms the circumferential contact with outer conductor 11 near the end of outer conductor 11, thereby strides across the AUI 23 of connector body 3 electric coupling outer conductors 11 to the connector end 25.
AUI 23 can be any desired standard or special-purpose interface.
Those skilled in the art will appreciate that cut cable 15 and connector end 25 are lengthwise position and the statements of exposure phase mutual relation that are used herein between each element that shows coaxial connector 1.Except the position that shows with respect to adjacent elements along the coaxial connector longitudinal axis; It is distolateral distolateral with connector that each Individual components all has cable, just a side of the cut cable separately of facing coaxial connector 1 15 of each element and connector end 25.
Grasp ring and 19 can remain in the connector body hole 5, for example, be positioned at and grasp ring groove 27.For the installation that is easy to grasp ring 19 (and at this other element that describes below; If any) and/or improve the characteristic that grasps grasp 19 pairs of outer conductors 11 of ring; Grasping ring groove 27 can form like this: cut cable grasps the ring groove sidewall and/or the bottom is the surface of being coupled to the clamping nut 31 of connector body 3, for example shown in Figure 4 and 5.
Holding ring screw thread 37 between the outer diameter part of connector body hole 5 and holding ring 31 also can provide as substituting maintenance characteristic 29.In order to make coaxial connector 1 to provide as the assembly that is ready to install; Holding ring screw thread 37 can make up with interlock groove 33 and interlock barb 35; To provide holding ring 31 can be set to be attached to the assembly of connector body 3; Thereby prevent the decomposition of inner member and/or lose, for example shown in Fig. 4-7.Keeping characteristic 29 to make up under the situation of holding ring screw thread 37 and interlock groove 33 and interlock barb 35, holding ring 31 with respect to connector body 3 via vertically advancing of generation receives the width that interlock barb 35 can move through in interlock groove 33 before interfering with interlock groove 33 sidewalls the restriction of screwing along holding ring screw thread 37.
In the alternate embodiment shown in Fig. 8-10, keep characteristic also can be included in the interference engagement structure 67 between connector body 3 and the holding ring 31, it is positioned in connector body 3 and holding ring 31 and is threaded at last and engages in together the process.Interference engagement structure 67 is used for when holding ring 31 is threaded onto connector body 3, preventing the disengagement of this holding ring 31/loosening.
Substituting ground, spring contacts 21 can be the metal spring rings with punching press that a plurality of springs refer to, for example shown in Figure 11 and 12, said spring refers to for example keep electrically contacting through holding ring 31 and connector body 3.
Preferably like Fig. 3,5,10,12, shown in 19 and 26, the ring-type wedge-shaped surface 39 in grasping ring groove 27 has tapering between the distolateral minimum diameter of the distolateral maximum gauge of connector and cable.Grasp ring 19 outer diameter part contact wedge-shaped surface 39, thereby through 15 advancing and radially inwardly driven along wedge-shaped surface 39 towards cut cable.
Grasp contacting and to encircle 19 turning along grasping between ring 19 outer diameter part and the wedge-shaped surface 39; Said turning can be by slyness; Advance along the smooth of it with promotion; Or substituting ground, grasping ring 19 can encircle 19 outer diameter part profile and be inclined to the parallel contact area that is formed with prolongation with the wedge surface of wedge-shaped surface 39 grasping between ring 19 and the wedge-shaped surface 39 through making to grasp.
When wedge-shaped surface 39 axial when traversing and/or the variable-diameter characteristic of the expansion/contraction that grasps ring 19 when running into any foozle of diameter of coaxial cable outer conductor 11 need have gap 52 (thereby, grasp ring 19 and be C shape) along the circumference that grasps ring 19.The width in gap 52 can be selected based on the difference that grasps the ring 19 minimum and maximum diameters that provide of expectation.
Grasp ring 19 grip surface 17 and have the directivity bias voltage and make when tensioning the outer diameter part surface that engages and grasp outer conductor 11 towards cut cable 15, allow outer conductor 11 when when connector end 25 moves, sliding through grip surface 17 simultaneously.Grip surface 17 can be formed (Figure 15-17) groove or the barb 47 of a plurality of annulars (Figure 13-14) or spiral; Said groove or barb 47 are provided with the inclined plane 49 of groove top that extends to the connector end 25 of each groove and/or barb 47 from the bottom portion of groove of cut cable 15, and the face 51 that only stops of adjacent grooves is converged to a point with inclined plane 49 at the top of groove.With the face 51 that only stops of inclined plane 49 opposed can be the face vertical with respect to the coaxial connector longitudinal axis; And/or only stop face 51 and can tilt towards connector end 25, so that the barb point digs into and keeps outer conductor 11 when attempting to advance towards the direction that cut cable 15 comes out from connector body hole 5.Grip surface 17 can be provided with the profile of characteristic of the specific solid outer conductor 11 of coupling, and for example size is suitable for mating the bow profile of wave groove of the solid outer conductor coaxial cable 13 of ripple of annular, for example shown in Figure 18 and 19.Similarly, crooked profile also can be the convex configuration, and its size is suitable for holding up (cradle) ripple peak.
Grasp the lengthwise movement scope that ring 19 has in grasping ring groove 27.When grasping ring 19 along wedge-shaped surface 39 towards connector end 25 when moving; For example when drawing the edge before the outer conductor 11 when cut cable 15 is inserted into the connector body hole 5 and contact the inclined plane 49 of grip surface 17; Grasping ring 19 will launch perhaps will begin equally towards connector end 25 lengthwise movement in grasping ring groove 27 to allow outer conductor to pass through.Because wedge-shaped surface 39 is tapered, therefore, when grasping ring 19, grasps ring groove 27 and increase with respect to the degree of depth that grasps ring 19 towards connector end 25 motions.Thereby, grasp that ring 19 can radially outward be expanded so that outer conductor 11 can be through grasping ring 19 and passing through towards connector end 25.On the contrary, in case expansion grasps ring 19 and grasps joint towards producing between the inside outer diameter part surface that is biased in grip surface 17 and outer conductor 11 of its relaxed state.If tension force is applied between connector body 3 and the coaxial cable 13 to draw outer conductor 11 towards cut cable 15; Grasping ring 19 abuts against cone-shaped wedge-shaped surface 39 and is driven; Reduce to grasp the degree of depth of ring groove 27 gradually, grasp ring 19 and be driven to along with grip surface 17 in the outer diameter part surface of outer conductor 11 and further increase and grasp conjugation thereby radially inwardly drive.Cut cable grasps the ring groove sidewall and can be sized to and be positioned at such position; Promptly in this position; Grasp ring diameter and be configured to make grip surface 17 firm engagement outer conductor 11, can radially inwardly not move and cause outer conductor 11 radially inwardly to subside above the permission level but grasp ring with respect to the outer conductor diameter.
In order to reduce to reveal through the RF in gap 52, can use overlapping notch features 54, wherein, the masked segment 56 that grasps first end 58 of ring 19 extends towards the respective cut part 60 of second end 64 that grasps ring 19, for example shown in Figure 20-25.When grasping ring diameter owing to contacting with wedge-shaped surface 39 when reducing, masked segment 56 extends across gap 52, and enters into notch portion 60, thus closing gap 52, and can not stop the changeability of the diameter that grasps ring 19.Gap 52 has reduced the RF leakage through it significantly through the sealing of overlapping notch features 54.
Realize with respect to grasping the flange edge 66 that further reduction that ring 19 RF reveals can be close to the connector end that grasps ring 19, for example shown in Figure 22-25.Flange edge 66 if exist, extends radially outwardly around the circumference that grasps ring 19, and comprises masked segment 56.Grasp ring groove 27 and can be formed with flange edge stage portion 80; Flange edge 66 is coupled in the said flange edge stage portion 80; Or substituting ground; Grasp and comprise the part that forms the flange edge stage portion between the connector end that ring groove 27 can be formed in connector body 3 and holding ring 31, for example shown in Figure 26 and 27.Flange edge 66 also can provide the additional loop mapping function that grasps, and flange edge 66 provided before the interconnection of the end of coaxial connector 1 and coaxial cable 13 and grasps the additional maintenance that ring 19 is grasping in the ring groove 27.
Grasp ring 19 and preferably formed by a kind of material, for example stainless steel or beallon, its hardness property is greater than the hardness property of the material of outer conductor 11, so that grip surface 17 can engage and grasp the outer diameter part of outer conductor 11 reliably.For the ease of making, gap 52 can be set in the stable state that grasps ring 19 and extend to the yardstick in the gap 52 greater than masked segment 56, encircles 19 thereby can have grasping of overlapping notch features 54 via traditional metal machining technique manufacturing.For fear of combining, block and hang on the wedge-shaped surface and/or the sharp edges of the wedge-shaped surface of swiping grasping to produce on ring 19 first and second ends, inclined-plane 69 can be applied to first end 58 and second end 64, for example shown in Figure 22-25.
