Definitions

  • This invention relates to coaxial connectors and more particularly to the means for connecting coaxial transmission lines thereto.
  • coaxial connectors are designed so that a coaxial transmission line may be attached thereto in only one predetermined manner.
  • For the connector to accept a coaxial transmission line in another manner of attachment it is often necessary to redesign the connector resulting in changed electrical characteristics therefor.
  • the same connector may not be used in production construction wherein a different manner of connection i-s required thereby giving rise to design problems in the possible differing electrical characteristics of the two connectors.
  • the requirement that only a like connector m-ay .be substituted for another connector also gives rise to problems in iield usage.
  • crirnping of the cable to the connector is generally used since it provides significant cost savings.
  • specialized crimping tools must be used to connect the new connector. Such tools are not always available.
  • connection of a coaxial transmission line may be made thereto in more than one manner.
  • shouldered portion adapted to peripherally receive the end of a threaded sleeve.
  • a nut is threaded therein and has means which bears against a sleeve to tighten it around the conductor.
  • the threaded sleeve and related structure is employed in lieu of the crimped sleeve.
  • FIGURE l is a cross sectional diagram of the female half of a coaxial connector with an embodiment of the present invention contained therein prior to assembly.
  • FIGURE 2 is a cross sectional view of the apparatus of FIGURE l in assembled form.
  • FIGURE 3 is a cross section of the apparatus of FIG- URE 2 taken along lines 3-3 thereof.
  • FIGURE 4 is a cross sectional diagram of the female half of a coaxial connector with another embodiment of the present invention assembled therewith.
  • FIGURE l a coaxial transmission line 10 is shown stripped so that the central conductor 12 thereof projects beyond the dielectric material 14 which in turn projects beyond the outer conductor 16.
  • the central conductor 12 of the coaxial transmission line 10 is shown attached by conventional means to a conventional contact 18 which in turn is insertable within the coaxial connector 20 where it is held by resilient dielectric member 22.
  • the coaxial transmission line 10 is shown in FIGURE 1 prior to its insertion in and connection to the coaxial connector 20.
  • the embodiment shown in FIGURE l is adapted for clamping of the coaxial transmission line 10 to the coaxial connector 20.
  • the body or Ishell 24 of coaxial connector 20 is provided with a rearwardly extending portion 26 forming a shoulder with the body 24 and a rearwardly extending tubular sleeve 28 forming a shoulder with the reduced portion 26.
  • the sleeve 28 of member 24 has circumferential grooves 30 cut in its outer surface, and has a passage therethrough internally sized to accept the central conductor 12 and dielectric material 14 therearound of coaxial line 10.
  • an outer sleeve 32 is mounted on the reduced portion 26 of member 24 in lixed relationship with respect thereto. This may be accomplished by any suitable means such ,as threading, brazing, welding or the like.
  • the sleeve 32 is internally threaded at the end 34 thereof.
  • a deformable clamping ferrule 36 is disposed about the outer conductor 16 of coaxial transmission line 10 and is internally sized to accept the outer conductor 16 when it is disposed about the sleeve 28.
  • the clamping ferrule 36 is of split-ring form comprised of a forward portion 37 which is essentially coaxial with the transmission line 10 and split through only at 35, and a tapered rearward portion which tapers inwardly therefrom and is partially split at 38 to form separate jaws 39.
  • a cam ring 40 of external diameter to permit the passage thereof within sleeve 32 has internally tapered end portions 42, either of which is engageable with the tapered jaws 39 of sleeve 34.
  • a hollow clamping nut 44 is disposed about transmission line 10 and is externally sized and threaded so as to be engageable with the threaded portion 34 of sleeve 32.
  • the apparatus of FIGURE l operates to clamp the coaxial transmission line 10 to the coaxial connector 20 as shown in FIGURE 2.
  • nut 44 is screwed inwardly to engage the cam ring 40 and compress the tapering jaws 39 of ferrule 36.
  • Cam ring 40 will impart a radial compression force on ferrule 36 which in turn imparts a radially compressive force on the outer conductor 16 of coaxial transmission line 10. Since at this time the outer conductor 16 of coaxial transmission line is disposed about the sleeve portion 28 of rearwardly extending member 24, the radially inward pressure will cause the outer conductor 16 to be held in gripping relationship with the circumferential grooves 30 cut therein.
  • a soft sealing gasket 46 is inserted about the coaxial transmission line 10 ⁇ between the nut 44 and the rearward end of cam ring 40. It is preferred that the soft sealing gasket 46 have a groove 48 molded therein. Thus, upon forceful engagement, the cam ring 40 will penetrate the gasket 46 to effect an outer compressive seal between the cam ring 40, nut 44 and the inner walls of sleeve 32, and an inner seal between caxn ring 40, nut 44, and the outer insulation 52 of coaxial line 10.
  • the aforedescribed apparatus has been for the clamping of a coaxial transmission line 10 to the connector 20.
  • the apparatus shown in FIG- URE 4 is used therewith.
  • the stripping dimensions of the coaxial transmission line 10 remain the same for the apparatus of FIGURE 4 as for the apparatus of FIGURES 1 through 3.
  • the central conductor 12 of coaxial transmission line 10 is mounted in the same manner as shown for FIGURE l.
  • the stripped outer conductor 16 of the coaxial transmission line 10, as in FIGURE 1, is expanded and axially advanced so that it is disposed about the sleeve 28 of the rearwardly extending member 24.
  • a deformable ferrule 54 is disposed about the outer conductor 16 and is crimped using a conventional crimping tool so that the outer conductor 16 is brought into gripping relationship with the circumferential grooves 30 cut in the sleeve 28 of rearwardly extending member 24.
  • a soft sealing gasket 56 is disposed about the ferrule 52 so as to effect a waterproof seal.
  • the threaded end 23 of member 24 secures a mating connector thereto.
  • both a clamp type connection and a crimp type connection may be effected therewith according to the present invention without changing the electrical characteristics of the coaxial connector.
  • a rearwardly extending hollow body member comprising a first reduced portion forming a shoulder with said body member and integral therewith and a second reduced portion forming a shoulder with said first reduced portion, said second reduced portion being integral with said first reduced portion and sized to accept therearound the external conductor of said transmission line in crimpable relation therewith, said rearwardly extending member being internally sized to accept the central conductor and dielectric material therearound of said transmission line, means for compressing the outer conductor of said transmission line into gripping relation with said second reduced portion and means spaced forwardly of said reduced portions shaped to secure a mating connector to said body member, said first reduced shoulderforming portion being sized and shaped to receive a sleeve means for accommodation of a thr-eaded tightening means forming said compressing means when it is desired to employ this form of compressing means in lieu of crimping.
