Definitions

  • the present invention relates generally to cable connectors and more particularly to connectors for coaxial cables for high frequencies, such as used in transmitter masts and the like, as set forth in the preamble of claim 1 and 2.
  • the handling of the connector is partly being facilitated by the fact that the connector according to the invention makes it possible to establish the connection between the center terminal of the connector and the inner conductor of the cable without using fastening tools and partly by the fact that the connector is delivered as a one-piece connector, so that various parts hereof may not be dropped during mounting of the connector on the cable.
  • an optimal placement of the connector on the cable is ascertained by providing indicator means on the connector, making it possible from outside to ascertain that a correct placement of the connector on the cable is in fact obtained.
  • a reduction of intermodulation distortion on the electrical signal after passage through the connector is according to the invention being obtained through a reduction of the number of separate components interacting electrically (and mechanically) with each other in the connector, and hence a reduction of the number of electrical contact surfaces inserted between the outer conductor of the coaxial cable and those parts of the connector, which shall be connected to the outer conductor.
  • the embodiment of the invention described in the detailed description of the invention thus only 2 contact surfaces between the outer conductor and the main body of the connector is present, which is the minimum number of contact surfaces possible.
  • the connector according to the present invention comprises (contrary to many prior art connectors) one tubular main body, which can receive said coaxial cable and provide direct electrical contact between the outer conductor of the coaxial cable and said tubular main body without any intermediary means between said tubular main body and said outer conductor, and which main body is provided with a center terminal, which center terminal is to be electrically and mechanically connected to the inner conductor of said coaxial cable, and a tubular bushing which can be attached to a rear portion of said main body, for instance by means of suitable threads provided on the outer surface of the main body and on a frontal portion of said bushing, and where at least said main body is to be electrically and mechanically connected to the outer conductor of said coaxial cable.
  • the rear portion of said main body is characterised in that it comprises a number of longitudinal slits cut through the wall of the rear portion of the main body, so that this portion is able to be compressed and/or expanded radially to ensure correct and reliable direct electrical contact between said rear portion of the main body and the outer conductor of the cable, and in that it is furthermore provided with means on a part of the inner surface of said rear portion, for instance in the form of threads to be brought into engagement with the jacket of said coaxial cable during the mounting of the connector on the cable, said mounting being performed for instance by screwing the connector unto the cable, and thus displacing the connector longitudinally relative to the cable.
  • the connector comprises a tubular support means, which is substantial rigid in the radial direction, positioned within said main body, so that said support means can be displaced longitudinally a certain distance within said main body, and where the outer diameter of said support means is slightly less than the inner diameter of a part of said rear portion of said main body, so that the gab thereby formed between the rear portion of said main body and said support means can accommodate the outer conductor of said cable.
  • Said support means comprises a radially outwardly projecting circumferential collar, against which the end of the outer conductor of the coaxial cable is being pressed, when said main body is being mounted on said cable, for instance by screwing the connector onto the cable, thereby resulting in a longitudinal displacement of said support means in the direction towards the center terminal of the connector.
  • said support means at the end hereof facing said center terminal of the connector is provided with a connecting portion connecting said support means with the outer surface of a rear portion of said center terminal, said rear portion of the center terminal being provided with a number of longitudinal slits through the wall of said rear portion of the center terminal, so that a longitudinal displacement of said support means in the direction towards said center terminal by means of said connecting portion causes said rear portion of the center terminal to be radially compressed against the outer surface of the inner conductor of said coaxial cable and by this compression providing a firm electrical and mechanical contact between said center terminal and said inner conductor.
  • said bushing can as previously mentioned be displaced longitudinally relative to said main body of the connector.
  • retainer means are provided between said main body and said bushing, which retainer means provide for the possibility to displace the bushing on the main body over a certain limited distance in the longitudinal direction, but which retainer means also make a complete separation of said bushing from said main body impossible, once the connector has initially been assembled.
  • the relative displacement between the main body and the outer conductor caused by said screwing of the main body unto the prepared end of the cable during mounting hereof has the further advantageous effect that due to the frictional movement between the main body and the outer conductor, dirt and remains of insulating materials adhering to the outer conductor of the cable, which dirt and remains of insulating material incidentally has not been properly removed during the preparation of the cable, will be removed during mounting of the connector on the cable, because the inner edges of said longitudinal slits cut in the rear portion of the main body will scrape off dirt and remains of insulation, said dirt and remains of insulation being able hereafter to accumulate in said longitudinal slits.
  • This feature further improves the performance and reliability of the connector according to the invention.
  • the end of the cable Prior to mounting, the end of the cable is prepared by exposing a suitable length of the outer conductor 7 by cutting off a corresponding length of the jacket 8. Furthermore, the inner conductor 5 is exposed in such a manner that the inner conductor 5 extends longitudinally beyond the end of the outer conductor 7. Finally, a suitable length of the insulating material 6 disposed between the inner conductor 5 and the outer conductor 7 is removed, leaving a cavity 18 between said conductors.
  • a prepared cable could for instance look somewhat like the one shown in figure 3. After preparation of the cable, the connector is mounted hereon as described in the following with reference to figure 1 and 2.
  • the bushing 3 of the connector Prior to the application of the connector on the end of the cable, the bushing 3 of the connector is displaced longitudinally as far as possible relative to the main body 2 of the connector towards the rear end of the connector, i.e. to the right on the drawings. It is not possible to remove the bushing 3 of the connector entirely from the main body 2 of the connector due to the presence of the retaining means 15, 16, 24, 25, 26 between the main body 2 of the connector and the bushing 3, the function of which retaining means will be described in detail in the following. This displacement leaves a part of the longitudinal slits 21 through the wall of the main body free for inspection from outside, so that the outer conductor 7 of the cable during insertion of the connector on the end of the cable can be viewed through said slits 21.
  • the connector is pushed over the end of the cable until the point where the end of the jacket reaches the thread 14 provided on the inner wall of the rear portion 22 of the main body 2. Thereafter the connector is displaced further in the longitudinal direction over the end of the cable by screwing the main body 2 of the connector onto the jacket 8 with the aid of said thread 14.
  • This further displacement of the connector relative to the end of the cable can be monitored by visual inspection of the outer conductor 7 through said slits 21 in the wall of the main body 2. It is thus possible by visual inspection to ascertain the correct longitudinal position of the connector on the end of the cable.
  • the retaining means comprise a connecting annulus 15 slidably positioned between the rear portion of the main body 2 and the bushing 3, one end of said connection annulus 15 being free to move longitudinally in an annular recess 26 provided in the rear portion of the main body 2, and the other end of said connection annulus 15 being provided with a circumferential recess 25 containing a retainer ring 16, which retainer ring 16 is able to move freely longitudinally in a circular recess 24 cut in the inner wall of the bushing 3.
  • the bushing 3 is screwed unto the main body 2 by means of the thread 27 for final connection between the main body 2 and the bushing 3.
  • the connector is finally provided with two sealing joints, for instance in the form of O-rings 10, 17, ensuring a hermetically sealed placement of the bushing 3 on the main body 2.
  • connection annulus 15 between the main body 2 and the bushing 3 serves a further purpose in that when the bushing 3 as a final step of the mounting of the connector on the cable is screwed as far as possible in the direction of the arrow A (see figure 1), the end of said connecting annulus 15 facing the center terminal 4 of the connector 1 comes into engagement with an outwardly directed circumferential protrusion 28 provided on the rear portion of the main body 2 and thereby presses the rear portion of the main body 2 firmly against the outer circumferential surface of the outer conductor 7 of the cable due to the presence of the support means 11, which is not able to yield in the radial direction, whereby a reliable electrical and mechanical connection and attachment is ensured between the main body 2 and the outer conductor 7 of the cable.
