Definitions

  • the present invention relates to solderless connectors suitable for use with semi-rigid coaxial cable.
  • solderless connectors are well-known and have been widely used in many applications for flexible and semi-rigid cable assemblies, there useful application has been limited to situations in which vibration and stress are not problems.
  • a basic requirement in providing a solderless connector for use in such extreme environment conditions is that of providing mechanical and electrical interconnection of high integrity between the outer conductor and the connector itself.
  • a recent attempt at providing such a connector is embodied in AMP Incorporated's SMA coaxial connector which is described and illustrated on Pages 261 and 262 of AMP Inc.'s catalog entitled “AMP Guide to RF Connectors,” Catalog 80-570 published 7/82.
  • the AMP connector for semi-rigid coaxial cables utilizes a ferrule or gripper ring which interconnects the main housing of the connector with the outer conductor of the semi-rigid cable.
  • the gripper ring in this design includes a plurality of teeth extending from the annular end of the ring axially of the connector and arranged to be deformed or bent radially inwardly to engage the outward conductor of the cable upon the application of a force to telescope the ferrule and housing together. By this telescoping action the teeth are bent inwardly to engage the outer conductor while the main housing achieves an interference fit with the ferrule thereby to retain the connector on the cable.
  • the mechanical and electrical integrity of the mounting of the connector on the cable involves, firstly, the integrity of the connection between the ferrule and the outer conductor of the cable and, secondly, the interference fit between the ferrule and the housing. Failure of either of these will destroy the integrity of the mounting of the connector on the cable.
  • the interference fit between the ferrule and the housing is subject to failure upon the application of a longitudinally acting force on the connector relative to the cable which is of a magnitude insufficient to damage the cable or the connection of the ferrule with that cable.
  • a solderless connector for semi-rigid coaxial cable comprising a connector housing including a portion defining a cable encompassing opening having cable engaging means formed integrally therewith and means to circumferentially compress said portion about a said cable, when in said opening, to bring said engaging means into engagement with said cable and to maintain that engagement.
  • annular monolithic housing 1 defines a cylindrical bore 2 of a diameter to accommodate in close spaced relationship the outside surface of a semi-rigid coaxial cable 3.
  • This cable comprises an annular elongate copper outer conductor 4 concentrically within which extends a copper center conductor 5 with a dielectric material 6 disposed therebetween.
  • a coupling nut 7 is mounted on the housing for rotation relative thereto about central axis 8.
  • the coupling nut has an inwardly extending annular flange 9 arranged to cooperate with an outwardly extending annular flange 10 on the exterior of the housing 1 to permit the mechanical and electrical interconnection of the connector cable assembly with, for example, a corresponding cable jack such as that illustrated in Figure 4, upon the engagement of the female thread 11 of the nut 7 with the corresponding male thread 12 (see Figure 4) of that jack.
  • a bushing 13 is pre-loaded onto the rear end 14 of the housing 1 prior to the assembly of the connector onto the cable 3.
  • the preloading of the bushing 13 serves to provide for ease of handling and holds the nut 7 captive.
  • the housing 1 has a cylindrical counterbore 15 concentric with the axis 8 at its rear end 14 with a plurality of elongate teeth 16 projecting inwardly from the cylindrical surface of the counterbore toward the axis 8.
  • the tips of these teeth define an imaginary cylindrical surface of the same diameter, prior to the mounting of the connector of a cable 3, as and coaxial with the bore 2.
  • teeth are provided. These rows each comprise four teeth, equally spaced apart round the circumference of the counterbore 15, lying in a plane normal to the axis 8.
  • the teeth are of generally symmetrical triangular cross-section and have a length, around said circumference, approximately equal to the space, around said circumference, between adjacent teeth.
  • teeth of asymmetric cross-section to asymmetrically resist longitudinal and/or torsional forces applied to the connector relative to the cable or of conical or frusto-conical form may be utilized without departing on the concept of the present invention.
  • the mounting of the connector onto the cable 3 is achieved by sliding the connector onto the cable into the position shown in Figure I with the bore 2 and the tips of the teeth 16 in close proximity to the outer surface of the outer conductor 4.
  • the housing 1 and bushing 13 are then telescoped together by the application of a telescoping force longitudinally of the axis 8 as may be applied by a hand operated tool adapted for this purpose.
  • This telescoping action compresses the rear end 14 of the housing circumferentially, and thereby moves the teeth 16 radially inwardly, by virtue of the interaction of cylindrical bore 17 of bushing 13 with the cylindrical outer surface 18 of the rear end 14 of the housing 1, the bore 17 being of a smaller diameter than the surface 18.
  • the radial thickness and outer diameter of the rear end 14 is chosen relative to the material and dimensions of the bushing 13 to provide a desired movement of teeth 16 radially inwardly toward axis 8.
  • the telescoping action is continued until the housing 1 and bushing 13 occupy the position illustrated in Figure 3 with the bushing 13 abutting the outwardly extending annular flange 10 of the housing.
  • the radially inward deformation of the rear end causes the surface of counterbore 15 to engage and the teeth 16 to engage and deform the surface of the conductor 4 to provide a positive mechanical and electrical interface therewith.
  • the circumferential extension of the teeth provides substantial annular communication between the housing and the outer conductor thereby to strongly resist the longitudinal movement of the housing on the cable upon the application of axial forces on the connector relative to the cable.
  • the circumferentially extending gaps between the teeth serve to resist torsional forces attempting to twist the connector around axis 8 about the cable.
  • the integrity of the mechanical and electrical interconnection between the outer conductor of the cable and the connector depends upon only a single interface, namely the interface between the teeth 16 and rear end 14 with the outer conductor and the cable.
  • housing 22 has a rear end 14 similar to that illustrated in Figures 1, 2 and 3 on which is preloaded a bushing 13.
  • housing 22 supports opposed electrically interconnected contacts 23 by means of a dielectric 24, one adjacent the rear end 14 for engagement with the center conductor of a cable upon which the jack 21 is mounted.
  • the forward end 25 has a male thread 25 to facilitate connection with a plug such as described with reference to Figures 1, 2 and 3, by means of engagement of the coupling nut 7 with the forward end 25; the center conductor of the cable upon which that plug is mounted engaging the other female contact 23 which is located adjacent the forward end 25.
  • annular face terminating the forward end 25 is adapted when the jack is connected to a plug as shown in Figures 1, 2 and 3, to sealingly engage an annular gasket 27 captively mounted in an annular groove formed in an exterior surface of housing 1 adjacent the outwardly extending flange 10, within the coupling nut 7.
  • Figure 5 illustrates a cable plug having mounting arrangements similar to those described with reference to Figures 1, 2 and 3 with the housing of this plug supporting electrically interconnected female and male contacts by means of a dielectric, the female contact being adapted to communicate with the center conductor of a cable on which the cable plug is mounted and with the male contact projecting into the interior of a coupling nut for engagement with a cable jack such as illustrated in Figure 4.
