Definitions

  • This invention relates to a coaxial tap-connector.
  • a coaxial tap-connector comprises a two part housing defining between the parts a passageway for a coaxial cable one housing part supporting a first probe arranged for penetrating the cable and engaging the core, the other housing part supporting a second probe, opposed to the first, and arranged to penetrate the cable and engage the core, the second probe being spring loaded for support of the cable core against the tip of the first probe, the first probe comprising a conductive core having the tip exposed from surrounding dielectric material and is characterised in that the first probe comprises a conductive shank portion formed at the tip with an enlarged diameter frustoconical head presenting a rear facing shoulder and a forward point for penetrating the cable, the dielectric material surrounding the shank portion and having an outer diameter corresponding to that of the enlarged diameter tip portion.
  • the second probe is similarly formed.
  • the connector of Figures 1 and 2 comprises a housing block 4, a back plate 6, a housing part 8, all of suitable insulating material, and a printed circuit board 10 receivable within a rear cavity of the block 4 and adapted to be retained by back plate 6 and screws 26.
  • a pair of spaced, channel- form projections 16 extend normally from a face of housing block 4 and are slidably receivable in respective channel guides 28 formed in housing part 8 for guiding the housing part 8 in rectilinear fashion towards the block 4.
  • a clamping screw 30 extends through housing part 8 to engage a threaded bore 20 in block 4 for urging the part 8 towards the block 4.
  • the block is formed with an arcuate recess 31 extending from end to end of the block 4, and the part 8 is formed with a complementary recess 33.
  • the recesses 31, 33 together define a passageway 32 for a coaxial cable 68.
  • a conductor engaging probe 12 is mounted in the block 4 and projects from a centre portion of the recess 31.
  • a pair of braid engaging contacts 14 are disposed in the recess 31, one on each side of the probe 12.
  • the probe 12 comprises a conductive pin 40, projecting at its rear end from the block 4 for connection to the printed circuit board 10 of Figure 1, and extends through a dielectric body 44 mounted in a cavity of block 4 and secured to the pin 40 against axial movement by an annual shoulder 42 formed on the pin.
  • the pin 40 is formed with an enlarged diameter head 34 offrustoconical form and presenting a rear facing shoulder 36, and a short length 38 of the pin extending rearwardly from the shoulder 36 is of reduced diameter.
  • the dielectric body 44 at its forward end 46, abuts the shoulder 36, and for a short length is of outer diameter equal to that of the head 34 before increasing rearwardly in tapering manner.
  • a support probe 48 is mounted in the housing part 8 in axial alignment with the probe 12 and is movably mounted within a bore by means of a set screw 64 acting through a biasing spring 62 and mounted in a threaded boss 66.
  • the probe 48 comprises a metal pin 56 mounted within a dielectric body slidably within the bore of the housing part 8.
  • the pin 56 has an enlarged diameter head 50, of frustoconical form corresponding in form and size to the tip of probe 12, and presenting a rear facing annular shoulder 52 from which extends a pin portion 54 of reduced diameter.
  • the dielectric body abuts the shoulder 52 and extends rearwardly about the reduced pin portion 54 over a length 60 of diameter equal to that of the head before increasing progressively in diameter about a rear portion of the pin 56 which has an annular shoulder 58 to secure the pin to the dielectric against relative axial movement.
  • the dielectric body is formed at its rear with a recess receiving the forward end of spring 62.
  • the plate portions 83 of the two contacts 14 are integrally formed by a rectangular frame having an aperture through which the probe 12 extends and having a rearwardly extending part for connection to the printed circuit board 10 of Figure 1.
  • the plate portions 83 are flat and the fingers 82, 84 extend normally therefrom, but in operation the plate portions 14 are driven into the recess to bend the plate portions and urge the points of the fingers 82, 84 together as seen in Figure 7.
  • the connector is assembled in the condition of Figure 2, and the cable 68, having core conductor 70, dielectric 72, braid shield 74 and outer insulating sheath 76 is positioned between the opposed recesses 31, 33.
  • the tip of the probe 12 is positioned substantially centrally of the recess 31, and that of probe 48 projecting slightly inwardly of the surface of recess 33.
  • the housing part 8 is drawn towards the block 4, and as shown in Figure 5, the tip of probe 48 engages and punctures the cable sheath 76, at one side whilst the tip 34, at the other side, pierces the sheath 76 and the braid shield 74 to penetrate the dielectric 72. Further closure of the block 4 and housing 8 to the figure 4 condition results in the tip 34 of probe 12 engaging the cable core 70 and partially embedding therein.
  • the screw 64 is now tightened to drive the probe 48 under the bias of spring 62, inwardly from the figure 4 condition, through the braid shield 74 and dielectric 72, to abut the core 70 opposite probe 12 and partially embed in the core in like manner.
  • the reduced uniform diameter lengths of the probes 12 and 48 indicated at 78 in Figure 6 and 80 in Figure 5 extend from the braid 74 to the core 70 of the cable.
