Definitions

  • the invention relates to an antenna socket for high frequency ranges according to the preamble of claim 1.
  • Antenna sockets previously on the market transmit frequencies up to approx. 860 MHz in compliance with the requirements imposed on the HF-tightness and consequently on the connection technology of the coaxial cables for both the inner conductor and the outer conductor.
  • antenna sockets suitable for very high frequencies in order to be able to transmit signals received from satellites after conversion and processing in the frequency range above 860 MHz, especially in cable television systems.
  • the transmission and decoupling of these very high frequencies places special demands with regard to HF tightness and, in connection therewith, to the connection technology of the Coaxial cable.
  • the pressure element is designed as a metal clamping arm which carries a plastic pressure pin and can be pivoted about an axis running parallel to the longitudinal axis of the coaxial cable in such a way that the pressure pin against the inserted inner conductor and presses it onto a flat connection contact which is molded into an abutment surrounding it. It has been shown that with the aid of such a clamping device for the inner conductor of the coaxial cable, the requirements with regard to HF tightness and in particular the mechanics, particularly with regard to strain relief, cannot be met. The clamp arm is locked in the operating position. Overall, therefore, the clamping device for the inner conductor cannot be adapted to different inner conductor diameters of the coaxial cable to be connected, or can only be adapted inadequately.
  • the invention has for its object to make an antenna socket according to the preamble of claim 1 with respect to HF-tightness and thus the connection technology suitable for very high frequencies and in particular for frequencies up to about 1.8 GHz.
  • connection of the outer conductors of the coaxial cables to be connected is also decisively improved with regard to the described requirements for the very high frequencies.
  • every clamping device for the outer conductor consists of a metal clamping arm which is arranged in the insertion direction in front of the inner conductor clamping device and which is pivotably mounted on the base carrier, which lies with a clamping surface against the outer conductor, and a metal clamping surface arranged on the base carrier and opposite the clamping surface, the clamping surface and the clamping surface being the outer conductor detect and clamp in the operating position, achieved by the measures according to claim 6.
  • the clamping arm adapts to the different diameters of the cable outer conductors, including their detected insulating sheaths, in such a way that complete contact and complete pressure is mechanically ensured on the full clamping surface due to the swiveling and vertical displaceability.
  • a safe electrical contact and a safe strain relief is achieved even for the very high frequencies.
  • a particularly expedient design which is also easy to handle, is achieved by the features of claim 7.
  • the guides can be easily formed and fastened to the basic carrier, and the clamping arm with its pivot pins can be simply inserted and a stop limitation can be made by simply deforming the upper slot ends.
  • a particularly favorable design both with regard to making contact and with regard to strain relief even with the most varied cable diameters is achieved by the ribbing according to claim 8.
  • the effect of the clamping ribs is reinforced by the design of the rib heights according to claim 9.
  • With the same force development when screwing the clamping arm the pressing pressure on the outer conductor and also on the insulated cable sheath recorded more strongly because of the reduced contact surface due to the ribbing, that is to say a line contact.
  • the strain relief is thus decisively improved.
  • An improvement in the shielding effect, in particular with regard to the very high frequencies to be transmitted, is achieved with the measure according to claim 10.
  • This shielding effect is significantly improved by the side shielding walls in accordance with the measure according to claim 11.
  • the measure according to claim 12 in turn leads to a safe ground contact and thus to an even greater shielding effect of the clamping arm in connection with the shielding walls inside the box.
  • the measures according to claim 13 ensure that the swivel mechanism for the swivel arm only acts when the clamping arm has been pulled up to the limit stop within the lateral guides.
  • the metal tongue acts like a spring tongue and thus leads to an automatic locking in the pivoting position of the clamping arm, so that the clamping arm cannot fall down unintentionally when the coaxial cable to be connected is installed.
  • the measure according to claim 14 entails an extremely simple design with the described safe contacting, strain relief and shielding.
  • the antenna socket initially has, in the usual way, a metal base support 1, which is also referred to as a chassis.
  • the usual coaxial plug-in elements 2 (plug or socket) for the plug connection of connecting cables are arranged on this base support.
  • On the underside is the usual circuit board 3, which carries the desired electrical components.
  • the antenna socket is closed below by the closure parts 4, which need not be explained in more detail here.
  • the antenna socket shown here is designed as a double socket in the usual way.
  • the embodiment of the invention described below therefore always relates to the training for the connection of two coaxial cables.
  • Each receptacle 6 is block-shaped from insulating material with lateral guide walls, as shown in FIG. 1, and whose function will be described below.
  • the connecting end of the wire end 10 forming the connection contact which leads into the socket, runs in a slot in a guide wall of the receiving piece 6, in the exemplary embodiment in the guide wall on the left in each case.
  • the clamping device for the inner conductor also consists of a pressure element which consists of a guide piece 13 which can be tightened by a screw 12 in the direction of the abutment 9 and which is displaceably guided on and in the receiving piece 6 and which carries a pressure piece 14.
  • the pressure piece 14 consists of insulating material.
  • the rest of the guide piece 13 is either made of plastic or, if the strength requires it, of a firmer material than the pressure piece, in particular of metal.
  • Each pressure piece 14, as can be seen when the parts in FIG. 1 are viewed together, is displaceably guided in the associated recess 8 of the receiving piece 6 surrounding the abutment 9.
  • Fig. 4 shows the guide piece 13 with its pressure piece 14 and the screw 12 on an enlarged scale, with respect to the abutment or receiving piece only with the parts used for explanation.
  • the recesses 8 are open in the direction of the coaxial cable to be inserted, the inner conductor to be inserted.
  • the surface of the abutment 9 is inclined transversely to the wire end 10, namely roof-shaped, profiled.
  • the associated pressure surface of the pressure piece 14 is profiled. If the pressure piece 14 is thus tightened against the abutment 9 with the inner conductor 10a inserted with the aid of the screw 12 and via the guide piece 13, the inner conductor 10a deforms in accordance with the upper profile running with the wire end 10 resting thereon and is thus securely contacted and mechanically fixed securely.
  • the clamping device for the outer conductor is designed in the following way:
  • a clamping arm 15 can be pivoted above the base support 1 about an axis lying in the direction of insertion behind the inner conductor clamping device and running transversely to the longitudinal axis of the connecting cable, and in lateral guides upward limited to stop perpendicular to the connecting cable longitudinal axis slidably mounted and in the operating position against the outer conductor of the coaxial cable, designated 16 in Fig. 4, screwed.
  • the lateral guides consist of vertical slotted guide rails 17, as can best be seen from FIGS. 2 and 3.
  • a lateral pivot pin 19 of the clamping arm 15 engages in the slots 18 of the guide rails 17.
  • the slots 18 are narrowed at the top to limit the stop, for example by angling a web as shown at 20 in FIG. 3. It can thus be seen that the clamping arm 15 is displaceable in the guide slots 18 perpendicular to the plane of the base support and also via the pivot pin 19 is pivotable.
  • the clamping surface of the clamping arm 15 is ribbed transversely to the longitudinal direction of the connecting cable by ribs 21 rounded in its longitudinal direction.
  • the rib sleeves are increasingly formed in the direction of insertion.
  • the ribs moving on the metal outer conductor of the coaxial cable are provided with a larger contact surface than the subsequent ribs, which lie on the insulating jacket of the cable, as can be clearly seen from FIG. 2.
  • the clamping surface with the ribs 21 of the clamping arm 15 is assigned a clamping support 22, which is also ribbed transversely to the longitudinal direction of the connecting cable, as shown in FIG. 2 in particular by the ribs 23 which show the increasing rib height and width the bearing surfaces are designed according to the ribs 21 on the clamping arm 15.
  • a metal tongue 24 is arranged on the base support between the lateral guide rails 17 and cooperates with a projection 25 provided on the clamping arm edge in such a way that the clamping arm in the position pulled up against the guide stop 20 according to FIG. 2 is pivotable and can be locked automatically in the raised position.
  • Fig. 2 shows this position.
  • the clamping arm 15 has, in its area surrounding the inner conductor clamping device, downward-facing side walls 26.
  • screen walls 27 are arranged in this area, that is to say at least in the area of the side cheeks 26, on the base support 1, which are additionally each covered with contact springs 28, here in the manner of cage springs, which thus act against the side cheeks 26 of the clamp arm 15 in its in Fig. 3 shown operating position firmly and resiliently.
  • the clamping arm With the help of the captive nut 29 held in the clamping arm 15, the clamping arm can be firmly screwed onto the screw pin 30 in the clamping and operating position.
  • the pressure piece 14 (FIG. 4) can either be fastened to the guide piece 13 as a special component, or it can be formed in one piece with the guide piece 13 when producing both parts from plastic.
