"Coaxial connection socket"

The invention relates to a coaxial connection socket and in particular to the one used for connection of the Antenna cable in television sets is used, with a resistance of 60 ohms.

The majority of modern televisions are designed as so-called all-current devices. It is necessary to Provide separating capacitors between the antenna cable and the device. In the known devices, these Separating capacitors housed in the device as part of the rest of the circuit. However, this results in various types Difficulties regarding the connection of the antenna and the cable routing.

The invention is intended to remedy this situation

V (3rden that at least on the back of the connection socket a cross-section adapted separating capacitor is attached.

If, according to the invention, the separating capacitor to the connection socket is attached, it does not need to be accommodated when designing the circuitry of the device more to be taken. In addition, those that otherwise occur when routing the cables and when connecting are omitted Trouble. The new connection socket can be wired in the usual way.

In a particularly advantageous embodiment of the invention it is provided that the separating capacitor is tubular and is provided in the area of its ends with circumferential, metallic connection flanges, of which one for fastening the capacitor to the rear end of the metal jacket forming the external contact of the socket serves. The condenser with its one splash is approximately coaxial with the jacket of the socket on the latter soldered or welded on. The socket according to the invention differs from the usual connection sockets only by the fact that they backwards something from the 3-opening capacitor is towered over. The free connection flange of the

The capacitor is connected to the line otherwise attached to the external contact of the socket ".

It has proven to be particularly advantageous if the connecting flange used for fastening is channel-shaped is trained. In this way, on the one hand, a separating coil size can be used for different diameters of the External contact of the socket can be used, since the channel-shaped flange has a relatively large diameter range capable of encroaching. In addition, the trough-shaped design of the flange results in a very good one Eentrierung of the capacitor, so that an almost coaxial position of the outer jacket of the socket and capacitor is guaranteed is.

The stability of the arrangement consisting of the isolating capacitor and connection socket can then be further increased, if the connecting flange used for fastening is at a distance from the associated pipe end of the separating capacitor is arranged on this. With such a design of the separating capacitor, it is possible to the pipe end adjacent to the mounting flange on the one between the outer contact and the center contact of the socket at the rear end of the socket arranged insulating material to stand up, so that a canting of the

Finally, it is within the scope of the invention that within of the tubular "ennkondensators another, with the center contact of the socket connected separating capacitor is arranged. For example, a conventional ceramic Find small capacitor use, one terminal of which is soldered or welded to the center contact, while the other connection protrudes backwards beyond the free end of the tubular separating capacitor and for connecting the normally connected to the center contact lead wire is used.

Further features, details and advantages of the invention emerge from the description of a preferred exemplary embodiment based on the accompanying drawing, in which a section through a connection socket is shown is.

The connection socket 1 has a cylindrical outer jacket 2, the front end 3 of which is flanged and mitpohrungen 4 is provided for fastening the socket 1 to a wall, not shown. The outer jacket 2 is made of metal and forms the external contact of the socket 1.

The center contact 5 of the socket 1, which is also formed by a cylindrical metal body, is provided with the aid an insulating disk 6 opposite the outer jacket 2 set. The front end 7 of the center contact 5 intended to receive a plug pin is provided with Slits 8 provided so that it can resiliently move outward. The rear end 9 of the center contact 5 penetrates the insulating material disk 6 and forms a solder lug 10.

In this respect, the embodiment corresponds to a conventional coaxial connection socket. This connection socket is now a tubular Irennkondensator 11 attached to the rear. This separating capacitor 11 consists of a tube 12, for example made of ceramic, with appropriate coverings. The tube 12 carries on its front End 13 a connecting flange 14 and at the rear end 15 a further connecting flange 16. The connecting flanges 14 and 16 are made of metal.

As can be clearly seen from the drawing, the connecting flange 14 is designed in the shape of a channel and spaced apart arranged from the front end 13 of the tube 12. It overlaps the rüc 'w-like end 17 of the outer jacket 2 and is soldered or welded to this. The front end 13 of the tube 12 rests on the insulating disk 6.

This arrangement ensures that the separating capacitor 11 coaxial with the jacket 2 of the connection socket 1 is arranged and secured against tilting.

The second connection flange 16 of the separating capacitor 11 closes flush with its rear end 15 a "b. It can, depending on the type of line to be connected, with be provided with a soldering lug 18.

Inside the tubular separating capacitor 11 is another, cylindrical in the embodiment Separating capacitor 19 housed, one terminal of which

20 is soldered to the eyelet 10, while the other connection 21 can be connected to a line 22.

As can be clearly seen from the drawing, the connection socket according to the invention due to the presence of the rear connection flange 16, the shielding of a coaxial line without difficulty be connected, the center line of which is connected to the connection

21 of the capacitor 19 or, if this is not available, can be connected to the soldering lug 10.
