Definitions

  • the present invention relates to connectors for coaxial cables of the kind set forth in the preamble of claim 1 and more particularly to the connection between the inner conductor of the coaxial cable and the centre terminal of the coaxial connector.
  • EP 0 994 527 with the same applicant as the present application discloses a coaxial connector provided with threads on the contact surface between the inner conductor of the cable and the centre terminal as mentioned above.
  • US 5,595,502 discloses a connector for a coaxial cable having hollow inner conductor, where the centre terminal of the connector during mounting of the cable on the connector is brought into the hollow inner conductor, and where the portion of the centre terminal inserted into the inner conductor is furthermore provided with threads engaging the inner surface of the hollow conductor.
  • a coaxial connector which is not provided with threads at the contact face between the centre terminal of the connector and the inner conductor of the cable is disclosed in DE 1905182 which is considered to represent the closest prior art.
  • the centre terminal of the connector is provided with a tapered end portion into which the inner conductor of the cable is inserted.
  • the receiving end of the tapered end portion presses radially inwardly on the inner conductor over a longitudinally rounded contact region, the extension of which depends on the tightening of the connector.
  • the object of the present invention to provide a connector for a coaxial cable which ensures a firm and reliable electrical and mechanical contact between the inner connector of the cable and the centre terminal of the connector without giving rise to the degradations of signal propagation at the interface between the inner conductor and the centre terminal as described initially.
  • a connector for a coaxial cable essentially comprising an outer bushing for providing an axial displacement of parts in the connector, whereby these parts are brought into mechanical and electrical engagement with the coaxial cable, the axial displacement being provided by screwing a thread provided on said bushing onto a corresponding thread provided on the main body of the connector, the connector being furthermore provided with a centre terminal attached to the main body of the connector via a tubular member and comprising an end portion for connection to the inner conductor of the cable, said end portion being provided with engagement means for engagement with corresponding engagement means provided on a tubular body coaxially and displaceably mounted in the connector, and where said end portion is a tubular body longitudinally provided with a number of slits facilitating the axial compression of the end portion around the inner conductor of the cable, and where the connector is furthermore characterised in that said end portion on the inner circumferential surface hereof is provided with an annular contact surface longitudinally extending over a predefined distance and protruding radially in
  • a connector for a coaxial cable essentially comprising a tubular main body 1 upon which a tubular outer bushing 2 can be screwed by means of appropriate threads provided on the outer surface of a portion of the main body and a corresponding inner surface of the outer bushing thus providing the possibility to displace the main body and the outer bushing relative to each other as mentioned in the description of prior art.
  • One effect of providing said displacement between the main body (1) and the outer bushing (2) is that the axially displaceable part 5 surrounding the inner conductor 10 of the cable will be displaced in the direction towards the centre terminal 3 as indicated by the arrow A in the Figure. Due to the engagement between the conical face 11 of the displaceable part 5 and a corresponding conical face 12 on the end portion 3' of the centre terminal 3, the end portion 3' will be pressed radially inwards towards the inner conductor 10, the end portion 3' being axially retained by engagement with a tubular member 6 by means of which member the centre terminal 3 of the connector is furthermore attached to the main body 1.
  • the end portion 3' of the centre terminal 3 is formed as a tubular member of an inner diameter that over the major longitudinal length of the end portion 3' is somewhat larger than the diameter of the inner connector 10 of the coaxial cable.
  • the inner conductor 10 is inserted into this tubular member approximately as shown in Figure 1.
  • the tubular member is provided with a plurality of longitudinally extending slits 15, typically 4 slits, although other numbers could also be used. The presence of these slits 15 facilitates the inwardly directed compression of the end portion 3' around the inner conductor 10.
  • the tubular member is on the inner circumferential surface hereof provided with an annular protruding contact area 14 encircling the inner conductor 10.
  • the inner diameter of this protruding contact area 14 is chosen such that it is possible during mounting of the connector on the cable to pass the inner conductor 10 longitudinally through this contact area 14 and further into the tubular member to a final position as for instance indicated in Figure 1.
  • the insertion of the inner conductor 10 of the cable into the end portion 3' is furthermore facilitated by the presence of the inclined end face 17 on the end portion 3'.
