fig3 is a cross - sectional view of the field appliable uhf connector 20 constructed in accordance with the preferred embodiment of the present invention . the several components of connector 20 include the coupling nut 22 , shell member 24 , dielectric 26 and center contact 28 . coupling nut 22 contains internal threads 30 and , at its back end has a flange 32 extending radially inwardly . as a comparison will show there are no structural differences between coupling nut 22 and prior art coupling nuts . shell member 24 has a wide cup - shaped forward portion 34 and a small cylindrical rearward extension 36 . the leading edge 38 of the forward portion is formed into a circumferential flange 40 extending radially outwardly . as the drawing shows , the flange 40 cooperates with flange 32 on the coupling nut to limit the forward movement of the nut . the walls 42 of the forward portion 34 converge toward the rearward extension . the angle of convergence is preferably about three degrees with respect to the longitudinal axis of the connector 20 . the angle can be as high a 6 °. the trailing edge or base 44 of the forward portion is normal to the longitudinal axis and preferably is gently concave on its inside surface . an opening is centrally positioned in the base . the rearward extension 36 , an integral part of the shell member , is elongated and has a passageway 46 . the passageway opens into the opening in the base of the forward portion . dimensionally the diameter of the passageway and opening preferably approximates the outer dimension of coaxial cable 10 . the coupling nut and shell member are preferably formed from brass . dielectric 26 is a solid cup shaped body formed from insulating material such as phenolic . the forward end , or face projects radially outwardly to provide a flange 48 . the side walls 50 are gently tapered inwardly from the flange to the base 52 of the dielectric . the degree of taper is the same as the angle of convergence on the small member . additionally the walls are provided with a series of steps 54 . the center of the dielectric is hollowed out to provide a passage 56 therethrough . the walls of the passage adjacent the base may be widened as shown to facilitate the insertion of the center contact 28 . center contact 28 is formed from a conductive metal such as brass into an elongated cylindrical member having a passageway 58 extending through it . the front end of the contact is reduced in diameter to provide a nose 60 . the contact is upset about halfway along its length to provide a retaining ring 62 . the contact is fixed in the dielectric by pushing it into the passage 56 from the front until ring 62 arrests further rearward movement . the back end 64 of the contact is flared outwardly as shown to lock the contact in the dielectric . fig4 a , b and c illustrate the steps taken in terminating coaxial cable 10 onto uhf connector 20 . coupling nut 22 and shell member 24 are slid onto the end of the cable in that order . various lengths of jacket 18 , braided shield 16 and inner insulation 14 are removed and the exposed shield flared out , as shown in fig4 a . the center conductor 12 is then inserted into the center contact 28 so that the end extends beyond nose 60 . this protruding end is bent over the nose as shown in fig4 b . the braided shield 16 is then formed or wrapped about the side walls 50 of the dielectric uniformly . preferably the shield also covers the rearwardly facing shoulder 70 on dielectric flange 48 . shell member 24 is then pushed onto the shield - wrapped dielectric 26 as far as it can go . this step can be facilitated by first placing the front end of the contact 28 against a firm surface . pliers 66 are then used to press the dielectric completely into the shell member 26 as shown in fig4 c . pressure is applied at intervals around the circumference to insure that the shell member flange 40 firmly abuts dielectric flange 48 with shield 16 squeezed therebetween . nose 60 of the center contact 28 is now firmly squeezed with pliers 66 to crimp the contact about center conductor 12 . the length of conductor protruding beyond nose 60 can be trimmed off to complete the assembly . for optimum performance , coupling nut 22 should be torqued firmly onto a mating jack ( not shown ) to insure that the dielectric is properly seated in the shell member . fig3 shows in cross - section an assembled uhf connector . note that the steps 54 on dielectric side walls 50 provide points of high force concentration to enhance the conductivity between the braided shield 16 and the shell member 24 . fig5 illustrates uhf connector 120 which is another embodiment of the present invention . coupling nut 22 is unchanged . shell member 124 has been changed to the extent of turning up the forward ends 300 . the shell member still possesses a flange 140 to cooperate with coupling nut flange 32 . dielectric 126 has no flange and non - stepped side walls 150 . the taper of the walls is about three degrees as with dielectric 26 to match taper of shell 124 . center contact 128 has a slot 302 in its nose 160 . generally the assembly of uhf connector 120 onto coaxial cable 10 is the same as that for connector 20 . the end of center conductor 12 is bent into slot 302 to facilitate its termination therein . fig6 a illustrates a field appliable uhf connector 220 . again the coupling nut for this connector is the same as coupling nut 22 . also the center contact 228 is the same as contact 28 . shell member 224 differs in that four tabs 304 , 306 , 308 and 310 are blanked out from its flange 240 , each tab being spaced 90 ° from its neighbor . dielectric 226 is the same as dielectric 26 except four slots 312 are provided on the circumference of its flange 248 at 90 degree increments . the inside wall 314 of each slot is preferably beveled . prior to assembly all four tabs are in a position parallel to the connector &# 39 ; s longitudinal axis . after dielectric 226 has been seated in shell member 224 , opposing tabs 304 and 308 are bent inwardly against inside wall 314 of slots 312 . tabs 306 and 310 remain in an extended position and abut the jack ( not shown ) when the uhf connector is mated therewith . tabs 304 and 308 serve to secure the dielectric 226 against forward movement . fig6 b is a plan view looking down on top of the connector to better illustrate the above - described features . fig7 a and 7b illustrate a method of packaging the several components of uhf connector 20 . this method requires that the dielectric 26 be molded so that a number of laterally extending tabs 316 be provided around the perimeter of flange 48 . without the braided shield , the dielectric 26 will slip into shell member 24 readily . while the dielectric is being held in the shell member , the coupling nut 22 is pushed over the tabs as shown to provide an interference fit therewith . this fit will hold the components together for shipment to the user . fig7 b is a plan view taken along lines 7b -- 7b in fig7 a to better illustrate the above - described features . the foregoing detailed description has been given for clearness of understanding only , and no unnecessary limitations should be understood therefrom , as some modifications will be obvious to those skilled in the art .
