Summary of the invention
In order to overcome above-mentioned prior art defect, the purpose of this utility model is to provide a kind of TNC type radio frequency (RF) coaxial connector that connects flexible cable with new Joining Structure, can connect diameter and be the semi-flexible cable of 8 millimeters, difficulty while effectively reducing attaching cable, improve the reliability after cable attaching, the rate of finished products while especially having improved cable welding and operating efficiency also realize the phase equalization of twin elbow formula connector assembly.
For achieving the above object, the utility model by the following technical solutions:
The TNC type radio frequency (RF) coaxial connector that connects flexible cable with new Joining Structure, comprise bend pipe 1, at bend pipe 1 head, be embedded with the lining 4 matching with cable shield size, by lining 4 and the cable shield being placed in bend pipe 1, weld, in described bend pipe 1 end, have draw-in groove, on described lining 4, correspondence position is with step, and 1 employing step of described lining 4 and bend pipe snaps in draw-in groove location, and is matched in clearance between lining 4 and bend pipe 1.
At bend pipe 1 afterbody, be provided with clamp cover 3, described clamp cover 3 is socketed on cable, and clamp overlaps 3 ends with boss, and boss snaps in the draw-in groove of bend pipe 1 afterbody cable is radially fixed.
The material of described clamp cover 3 is nylon, and internal diameter is 8mm.
The internal diameter size of described lining 4 is 7.4mm.
It is 12mm that described bend pipe 1 adopts external diameter, the copper tube that wall thickness is 1mm.
By swivel nut 7, bend pipe 1 and shell 6, lining 4 is fixedly clamped between insulator 5 and bend pipe 1.
Compared to the prior art, tool has the following advantages the utility model:
1, owing to being embedded with lining at bend pipe head, by lining and the cable shield being placed in bend pipe, weld, because bush structure size matches with cable shield physical dimension, dwindled welded gaps, the volume and weight of lining is much smaller than bend pipe, solve when welding welding position inhomogeneous problem of being heated, effectively improved soldering reliability, rate of finished products and operating efficiency.In addition, lining is with adopting step to snap in draw-in groove location between bend pipe, and be matched in clearance, in the time of need to adjusting cable assembly phase place or assembly and occur defective item, only the soldering group zoarium of lining and cable need be pulled out in the lump, add the welding position of capable of regulating lining and cable after hot melt tin, thereby realize the phase equalization of twin elbow formula connector assembly, further improve the rate of finished products of cable assembly product.
2, at bend pipe afterbody, be provided with clamp cover cable is radially fixed, reduced bend pipe with the attaching gap between cable, cable is radially fixed, improved cable attaching stability.
3, bend pipe 1 employing external diameter is 12mm, wall thickness is the copper tube of 1mm, compare the internal diameter size of bend pipe is strengthened with existing bent-tube boiler connector, reduce cable and packed difficulty into, effectively improve damage and the distortion of cable when cable passes bend pipe, improved the radio-frequency performance index of bent-tube boiler radio frequency co-axial cable subassembly; In addition, cable need not make with lubricator when the bend pipe, more easy to clean after cable assembly has been welded.
In sum, the utility model has guaranteed stability and the reliability after cable and connector attaching, rate of finished products while having improved cable welding and operating efficiency, improved the radio-frequency performance index of bent-tube boiler radio frequency co-axial cable subassembly, realized the phase equalization of twin elbow formula connector assembly.
