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. 860MHz in compliance with the requirements imposed on the HF-tightness and thus in connection with the connection technology of the coaxial cables for both the inner conductor and the outer conductor.
• Increasing numbers are now desired.
• the transmission and decoupling of these very high frequencies places special demands with regard to HF tightness and, in connection therewith, with the connection technology of the Coaxial cable.
• the pivotable metal clamping arm acting in the manner of a clamp is only pivotable about an axis running parallel to the longitudinal axis of the coaxial cable to be inserted.
• the clamping surface and the clamping pad are smooth throughout. It has been shown that with the aid of such a clamping device for the outer conductor of the coaxial cable, the requirements with regard to HF tightness and the mechanics, in particular also with regard to strain relief, cannot be met. This applies in particular to the fastening and electrical connection of cables of different diameters.
• 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 1.6 GHz.
• clamping arm can be pivoted about an adapter lying in the insertion direction behind the inner conductor clamping device and extending transversely to the longitudinal axis of the connecting cable, and can be moved upward in side guides with limited stops perpendicular to the longitudinal axis of the connecting cable on the base support and in the operating position against the outer conductor is screwable. This ensures that even cables with different diameters can always be held over the entire area with complete electrical contact and can also be completely relieved of strain.
• the clamping arm according to the invention adapts to the different diameters of the cable outer conductors due to the swiveling and vertical displaceability on that a complete contact and complete pressure is always ensured in mechanical terms on the full clamping surface.
• 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 2.
• the guides can be easily formed and fastened to the base support, and the clamping arm with its pivot pins can be easily inserted and a stop limitation can be made by simply deforming the upper slot ends.
• the measures according to claim 8 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 in the manner of 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 9 has an extraordinarily simple design with the described safe contacting, strain relief and shielding.
• connection of the inner conductors of the coaxial cables to be connected is also decisively improved with regard to the described requirements for the very high frequencies.
• each clamping device for the inner conductor consists of an abutment made of insulating material held on the base support with a connection contact leading to the inside of the socket and a pressing element a laying in the operating position against the inserted inner conductor and pressing this against the terminal contact pressure element made of insulating material achieved by the measures according to claim 10.
• the measure of claim 11 ensures that when the pressure element is tightened, the inner cable conductor is deformed on the transverse end of the wire and thus an increase in the safety of the mechanical and electrical system of the inner conductor is achieved.
• This security can be increased by the measure according to claim 12, whereby an increased deformation of the inner conductor is achieved on the wire end.
• FIG. 1 is a diagrammatic, exploded exploded view of an antenna socket according to the invention
• FIG. 2 is a perspective view of the antenna socket with the clamp arm pivoted up
• Fig. 3 is a diagrammatic representation corresponding to Fig. 2 with: in the operating position pivoted and screwed clamping arm and
• Fig. 4 is a detailed perspective view of the clamping device according to the invention for the inner conductor of the coaxial cable to be connected.
• 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-in 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 connector shown here is designed as a double connector in the usual way. The embodiment of the invention described below therefore always relates to the training for the connection of two coaxial cables.
• the clamping device according to the invention for the inner conductor of the coaxial cable to be inserted laterally into the antenna socket is first described.
• two receptacles 6 made of insulating material are passed, which are held on a crossbar 7 made of insulating material below the base support.
• An abutment is formed in the recess 6 of each receptacle 6, as can be seen more clearly in a schematic illustration at 9 in FIG. 4.
• a wire end is placed transversely to the inner conductor 10 to be inserted (FIG. 4) of the coaxial cable to be connected, the further course of which is led downwards to the respective connection to the electrical components of the printed circuit board.
• Each receptacle 6 is block-shaped from insulating material with lateral guide walls, as shown in FIG. 1, and whose function will be described in the following.
• 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 6 of the receiving piece 6 surrounding the abutment 9. Fig.
• 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 in the antenna socket 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 extending 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 16 are narrowed at the top to limit the stop, for example by bending 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 15 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 connecting cable longitudinal direction, 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 temporal guide rails 17, which cooperates with a projection 25 provided on the clamping arm edge in such a way that the clamping arm can be pivoted in the position pulled up against the guide stop 20 according to FIG. 2 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, 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 clamping 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.
