Definitions

  • the invention relates to a device for connecting a coaxial connector to a coaxial cable according to the preamble of claim 1.
  • Such coaxial cables with a corrugated outer conductor and possibly a corrugated inner conductor, including the correspondingly mounted connectors are used in different sizes and capacities for the transmission of high-frequency energy, for example in mobile radio networks, radio and television systems, radio relay systems, radar and satellite ground stations, etc., and are very popular worldwide large quantities are used.
  • an extraordinarily good assembly quality is required for the connection between the conductor parts of the coaxial connector and the corrugated outer conductor or inner conductor of the coaxial cable, in order to meet the high electrical and mechanical requirements, in particular with regard to good contact and loss-free transmission.
  • connection is made, for example, of the outer conductor the corrugated cable to the corresponding outer conductor of the coaxial connector by screwing a contact sleeve in the form of an intercepting sleeve onto the outer cable of the cable up to the stop on the plastic insulating jacket of the cable.
  • the protruding outer conductor tube of the corrugated cable is then flanged outwards by 90 ° by hand or by means of complex mounting devices, so that it lies against the end face of the screwed-on contact sleeve.
  • the corrugated inner conductor tube is connected to the inner conductor connector.
  • an inner conductor contact piece is screwed into the inner cable conductor, whereupon a correspondingly protruding end of the inner cable conductor is flanged inward on a conical part of this inner conductor contact piece, specifically by about 45 °.
  • the flanging of the cable conductor corrugated tubes causes the mechanical fixing of the contact sleeve or the inner conductor contact piece on the relevant cable conductor; on the other hand, the flare also forms the electrical contact surface. This means that the electrical quality of the connection between the coaxial cable and the coaxial connector depends crucially on the quality of the flare.
  • the invention has for its object to design the connector of the generic type in order to eliminate the disadvantages described so that it can be easily and quickly assembled or disassembled without special tools and with simple construction of its components both the electrical as well as the mechanical requirements to a large extent.
  • such a contact sleeve which forms a collet with resilient clamping segments at its plug-side end;
  • This collet has a conically extending pressure surface and can be pressed radially against the corrugated cable conduit by a pressure cone which cooperates with it on the plug side.
  • the contact sleeve is fixed on the relevant corrugated cable conductor in an extremely effective manner;
  • the radially resilient tensioning segments ensure defined contact in the first corrugation or pitch of the cable conductor corrugated tube.
  • This contact at the point mentioned is of crucial importance, and this is achieved according to the invention in that the corrugated tube adapted to the cable conductor, for example designed as a profile thread engaging part or threaded part of the contact sleeve is rotated 360 ° after the first pitch.
  • the clamping segments of the collet can spring and due to their radial clamping caused by the plug-side pressure cone in the first pitch of the relevant cable conductor corrugated tube can be pressed over a circumferential angle of 360 ° and achieve a defined contact.
  • the contact sleeve designed according to the invention is preferably made of a material, for example of silver-plated brass, which has good high-frequency conductivity properties.
  • the threaded part or profile thread of the contact sleeve preferably extends over its entire length including the collet.
  • the collet segments of the collet are designed such that they contact the first pitch of the corrugated cable conduit in their radially clamped position caused by the pressure cone on the plug side.
  • the collet is offset from the rest of the contact sleeve by an annular groove which has a greater depth than the thread grooves of the profile thread.
  • annular groove the resilience of the individual clamping segments of the collet can also be achieved in another suitable way, for example by means of a correspondingly reduced wall thickness of the collet.
  • the connecting device according to the invention for connecting the outer conductor part of the coaxial connector to the corrugated cable outer conductor tube is used, the arrangement is such that the profile thread of the contact sleeve is an internal thread and that the conical running pressure surface of the collet is located on its outer circumference.
  • the plug-side pressure cone is provided on the inner peripheral surface of the connector housing forming the outer conductor part.
  • the connecting device according to the invention is provided for connecting the inner conductor part of the coaxial connector to the corrugated cable inner conductor tube, the profile thread of the contact sleeve is an external thread, and the conical pressure surface of the collet is located on its inner circumference.
  • the plug-side pressure cone is then provided on the outer surface of a contact bolt, which can be screwed into the contact sleeve with an externally threaded part at one end for radially pressing the tensioning segments onto the inner cable of the cable, and with a cylindrical section for the spring-loaded coupling at its other end has the inner conductor part of the coaxial connector.
  • the inner conductor contact sleeve has a stop in the form of an annular collar at its plug end, which is provided at the free end of the collet and protrudes outwards.
  • the invention thus enables the previously known assembly times and costs to be reduced by up to 50% and more. Another significant advantage is that special tools are used to make the connection are not required. This means that assembly at the construction site can be carried out without any problems. Any necessary phase adjustment that causes the cable to be shortened can also be easily accomplished in a short time.
  • the contact sleeve according to the invention can, as described, not only be designed as a profile thread on its inner circumference, but also as a corrugated part which is adapted to the corrugated jacket of the cable outer conductor tube. This results in further manufacturing advantages.
  • the invention thus results in extremely advantageous simplifications overall in the construction of the connector parts. This enables considerable savings compared to known connecting devices.
  • the connecting device shown is used to connect a coaxial connector 1 to a coaxial cable 2.
  • this coaxial cable 2 is designed as a flexible copper corrugated cable and has a plastic sheath 3 for this purpose
  • a contact sleeve 7 For the connection of the corrugated cable outer conductor tube 4 to the corresponding outer conductor part of the coaxial connector 1, that is to say to the connector housing 6, a contact sleeve 7 is provided which has the configuration shown in FIGS. 1, 2 and 3.
  • This contact sleeve 7 has a threaded part 8 in the form of an internal thread, which is designed as a profile thread adapted to the thread of the cable outer conductor 4. It can thus be screwed onto the cable outer conductor 4 in a simple manner, in such a way that the free end of the cable outer conductor 4 is flush with the plug-side end of the contact sleeve 7.
  • the contact sleeve 7 has at its plug end a collet 10 with resilient clamping segments 11, which are formed in the illustrated embodiment in that the collet 10 is provided with four axial slots 12 arranged at the same distance from one another.
  • the collet 10 is provided with four axial slots 12 arranged at the same distance from one another.
  • the threaded part 8 of the contact sleeve 7 extends over its entire length including the collet 10.
  • the spring and clamping function of the collet 10 To ensure this is designed such that it is offset from the rest of the contact sleeve 7 by an annular groove 13 which has a greater radial depth than the thread grooves 14 of the profile thread 8 (see FIG. 2 of the drawing).
  • the collet 10 or its resilient clamping segments 11 have a conical pressure surface 15 on their outer circumference. This interacts with a correspondingly conical pressure cone 16, which is provided on the inner circumferential surface of the connector housing 6 forming the outer conductor part, in such a way that the resilient clamping segments 11 of the collet 10 in the radially clamped position caused by the plug-side pressure cone 16 complete first pitch of the outer cable 4, ie contact over a circumferential angle of 360 °.
  • this plug inner conductor part is a spring sleeve 21 which is held centrally in the coaxial plug 1 by means of an insulating disk 22 fixed in the plug housing 6.
  • the conical pressure surface 115 of the collet 110 is located on the inner circumference of the collet 110.
  • the collet 110 or its resilient clamping segments 111 are offset from the remaining part of the inner conductor contact sleeve 107 by an outer annular groove 113.
  • this outer radial annular groove 113 has a greater depth than the thread grooves 114 of the profile thread 108 in order to guarantee the resilience of the tensioning segments 111.
  • the pressure cone 116 which interacts with the inner conical pressure surface 115 of the inner conductor contact sleeve 107, is provided on the outer surface of a contact bolt 23, as can clearly be seen in FIG. 1.
  • this contact pin 23 has a cylindrical section 25 which, for the purpose of coupling with the inner conductor part of the coaxial connector 1, can be inserted into the correspondingly designed spring sleeve 21 and fixed there by means of an inner conductor central screw 26.
  • the contact sleeve 107 To screw the inner conductor contact sleeve 107 into the corrugated inner cable 5 over a predetermined screw-in length, the contact sleeve 107 has a stop 27 at its plug end. This has the shape of an outwardly projecting collar and is provided at the free end of the collet 110.
  • the design is such that the contact sleeve 71 has no threaded part on its inner circumference, but has an engaging part 81, which is designed as a corrugated part adapted to the corrugated tube of the cable outer conductor 4.
  • This corrugated part 81 of the contact sleeve 71 can thus also easily be clamped onto the corrugated jacket of the cable outer conductor 4, in such a way that the front free end of the cable outer conductor 4 is flush with the plug-side end of the contact sleeve 71, as shown in FIG assembled position of the two aforementioned parts according to FIG. 8 can be seen.
  • the contact sleeve 71 forms the aforementioned collet 10 with the individual resilient clamping segments 11 at its plug-side end.
  • the latter are also formed here in that the collet 10 is provided with eight axial slots 12 ′ arranged at the same distance from one another.
  • the corrugated part 81 of the contact sleeve 71 extends over the entire sleeve length, so that the desired spring and clamping function of the collet 10 is guaranteed with certainty, at least over the complete first corrugation of the cable conductor corrugated tube 4. As is also the case with the previously described first embodiment, this is brought about by the fact that the conical pressure surface 15 provided on the outer circumference of the contact sleeve 71 interacts with the correspondingly conical pressure cone 16 of the plug housing 6.
  • the basic features of the illustrated connecting device essentially correspond to the embodiment according to FIG. 1, but not screws are provided for fixing the coaxial connector 1 on the coaxial cable 2, but instead a threaded ring 82 , which is screwed onto the connector housing 6 in the manner shown. There is also an end screw 83 is provided, which is pressed against the threaded ring using a sealing compound 84.
