Definitions

  • The. invention is illustrated as being embodied in the male. section of a. male and female. detachable connector .for coaxial cables but the inventionl is by no means con- .fiued to thisv particular use.
  • An important object. of the. present invention .is; to :providemeans for. obtaining a'firm clamping contact with thebraided metal of .thecoaxial conductor without transmitting this force radially inwardly of the cable.
  • Another. "object of, the. invention. is to provide axsimulztaneous clamping action on both the braided sheath.
  • a further object of. the invention .is. .to provide .a coaxial connector which can be installed 'on. the endqof theica'ble in a. very minimum amount of timeand. without use of special tools.
  • Yetxanother object of. the invention is to provide an assemblywhich can be disassembled and repaired in the field.
  • Fig. 1 shows a longitudinal section throughv one section of aconnector. embodying the present invention.
  • Fig. 2 is a similar section showing a slightly modified arrangement.
  • a flexible coaxial cable is shown. at 10.
  • This cable includes a central or axial conductor 11, an inner insulation jacket 12-, an outer coaxial conductor :or electrical sheath 13 which. may beoif woven or braided copper wire construction, and an external layer of pl-astically deformable insulation 14.
  • the sleeve is externally threaded at 20 and has a non-circular wrench-receiving surface 21.
  • the female sleeve 16 has a bore 22 extending from its inner end and which is internally threaded at 23 to receive threads 20. About midway on the sleeve the bore has an annular shoulder 24 and a bore section 25 of redueed diameter extending to its outer end; The sleeve has a reduced 'outer-diametershown- 26-Which is externally threaded at'27a'nd has-an outer terminal section "30 of about the same diameter 'asse'ctfon- 26;
  • the wire-receiving sleeve portion 34 is shown insection and the remaining portions in elevations.
  • the shouldered portion' has a transverse opening 35 through "which the forward end of the axial conductor, lfl passes and is soldered therein.
  • Thezinnerinsulation jacket 12 is removed as far as line 36' where the axial 'conductorenters sleeve portion 34.
  • An insulating sleeve 41 having an enlarged counterbore section 42 encloses sleeve, 34 and the end of inner insulation jacket 12.
  • A, sleeve 44 .forming one 'of the. principal structural elements of the present invention is now slid over the insulation jacket and back between the braid and said jacket.
  • This sleeve hasan'inner diameteras to fit snugly over the insulation and has. an annular flange 45 at 'its outer end which fits within bore .22 of male coupling sleeve 15,.
  • a sleeve 50 formed of resilient but noncompressible material. and' at each end, of this 'sleeve metal washers '51. and "5.2 are. positionedjin order to prevent rotation imparted. to either of the-relativelyrotatabl'e members.1516., in tighteningv the assembly, to :be "im- 'parted to the sleeve 5.0. and. thus distort it by torsion-a1 forces.
  • Thev outside diameter .ot the sleeve is substantially the same as that. of. bore 22.
  • Various materials can be used for forming- .s'leeve 5.0 and.
  • an insulator 53 is received in snug fit relation in the outer end of bore 25 intubular member .16 which. .has a. bore .54 to receive second section 32 of the male. connector 31 and acounter-bore 55 at its outer end.
  • the cable is moved .intomale coupling sleeve 15 a distance one or two. inches to the right of the position shown in Fig. 1. Washer-sf 51-52 with, the resilient sleeve 50-therebetweenare now placed on the outer insulation 14.
  • the metal sleeve 44 is,..-now slipped'into the annular area between the braid whichhasnow been straightened, and the inner insulation jacket.
  • The: cable is now drawn to the left to the position of Fig. 1 and theterminalisection 43-o the braid. is between-washer 52 andilange 45.
  • Insulation 41 is now-fitted .iniplace-and-the. inner'cond'uctorismoved .intoopeningj34 and. soldered.
  • Insuiatbr 53' is. next; assembled on sectionv 32 of the male: contact-:31
  • the principal purpose of the washers 51-52 is to facilitate relative rotation between the two parts of the tubular housing and that if these washers are omitted the internal shoulders will move against the ends of the plastic sleeve and compress the ends toward each other.
  • the female section of the connector may be the same as the male connector insofar as the contact means for the braid or outer conductor is concerned. Accordingly only a fragmentary showing of the female connector is made and this includes a female connector member having an outer section 60 to receive male portion 31, a shouldered section 62 similar to section 33 and having a solder opening 63 and an inner sleeve section 64 to receive central conductor 65.
  • female sleeve 60 may have longitudinal slots (not shown) to cause it to exert a constrictive action on the male contact 31.
  • Fig. 2 shows only a slight modification in the construction of the connector.
  • Coupling sleeve 78 with its wrench receiving surface 79 is similar to coupling sleeve 15.
  • the coaxial cable including central conductor 80, inner insulation 81, braid 82 and outer insulation 83 is the same as that shown in Fig. 1 and the bore 84 in coupling sleeve is shown as having a larger diameter than the cable.
  • the other coupling sleeve 85 has the same threaded engagement 86 with coupling 78 and has a bore 87 shown as having a larger diameter than resilient sleeve 90 and washers 91-92.
  • the metal sleeve 93 which fits over inner cable insulation 81 has flange 94 and the section 95 of the braid overlying sleeve 93 is shown as being outwardly displaced from the remainder of the braid.
  • the braid terminal 96 is positioned between washer 92 and flange 94.
  • a connector for the outer conductor of a coaxial cable provided with an inner insulation between inner and outer conductors and an insulating jacket over the latter comprising a metal tube of substantially uniform diameter throughout its length, positioned between the outer conductor and the inner insulation, a plastically deformable sleeve enclosing the outer insulation in the area of the metal tube and extending at each end thereof to a point which is not beyond the adjoining end of the tube, a two-part tubular enclosure for the deformable sleeve and having a screw threaded engagement therebetween and provided with internal shoulders, and a washer of the same internal and external diameter as the deformable sleeve positioned at each end of said sleeve, whereby relative rotation between the two parts of the tubular enclosure forces the washers against the ends of the plastic sleeve and moves the ends thereof toward each other without any appreciable longitudinal movement of the sleeve relative to the outer insulation, the bore in the enclosure initially being of such size as to receive the s
  • a connector for an outer braided conductor of a coaxial cable provided with an inner insulation between inner and outer conductors and an outer insulation over the latter comprising a metal tube of substantially uniform diameter throughout its length positioned between the outer conductor and the inner insulation and having a flat annular flange at its forward end contacted by the ends of the braided conductor in the area of the metal tube, a plastically deformable sleeve enclosing the outer insulation in the area of the metal tube and extending at each end thereof to a point which is not beyond the adjoining end of the tube, a two-part tubular enclosure for the plastic sleeve and having a screw threaded engagement therebetween and provided with opposed, internal shoulders, and a washer of the same internal and external diameter as the deformable sleeve positioned at each end of the sleeve, whereby said relative rotation between the two parts of the tubular enclosure forces the washers against the ends of the plastic sleeve and moves the ends thereof toward each other without any
