Connections 9-10 on the other side in the component chamber 4 are formed with a longitudinal slot 24-25, through which - as can be seen in FIGS. 3? ig. Finally, as is shown in Pig. 2 for the pin 16 of the can body 1, it can be used with regard to the opening or closing of the connector on or in. the outer conductor sockets 11 or 12 occurring forces are advantageous if the pins 15 _} 16 are formed with stops for the outer conductor sockets. This is achieved in simple wines by the fact that the diameter of the peg, e.g. the peg 16, is stepped off in such a way that it corresponds to the inner diameter of the sleeve-like attachment 23 in the area of its end face 18 and then, for example, the outer diameter of the attachment 23 in the other areas so that the projection 23 rests against the diameter shoulder 28 when the can body 1 and the wall part 6 are plugged into one another.

The component chamber 4 on the side facing your receiver the box is sealed against high frequencies and serves as a cover for the second Y / andungteil 2 first wall part 6 also formed with an annular hand 29 protruding into the second wall part 2 and with the entire edge, the height of which is selected to be approximately half the depth of the pot 2 of the second wall part, inserted into this wall part, so that the edge 29 is in contact with the inner wall of the can body. The outer diameter of the to achieve a certain elasticity, possibly with longitudinal slits The annular rim 29 formed is selected to be somewhat larger than the actual inner diameter of the pot 2. Its inner diameter is, however, the outer diameter of the annular in the common plug-in area of the two parts The edge of the wall part 6 is adapted, so that a shoulder 30 is formed, which acts as a nesting of the wall parts 2 and 6 limiting stop is used.

of the edge an annular surface 31 resting on the support ring 3 of the second wall part is formed. In this way, another stop 32 is created which limits the plugging into one another of the wall parts.

The antenna socket is therefore in the assembled state of the wall parts 2 and 6 in the connection area of the wall parts with each other and in the plug-in area between the sleeve-like lugs 22, 23 of the outer conductor sockets of the first wall part 6 and the pins 15, 16 of the second wall part. 2 with inserted connectors on the front side of the receiver to the outside sealed against high frequencies, ie the electrically sealed seal is sealed against high frequencies for the respective frequency range to be transmitted. The advantage of the embodiment according to the invention of the first wall part serving as a cover for the second wall part is primarily that a simplification and a more favorable construction of the entire can is achieved. The developments and details of the first wall part shown in FIGS. 1 and 2 achieve further significant advantages. Thus, when the two wall parts are connected to form a hollow space that is delimited on all sides and conductive material as a component chamber, a mechanical and electrical design of the wall parts is advantageous in terms of the transition points in the connection and contact area between the wall parts and the wall parts and the coaxial receiver-side connections enables. In an advantageous manner, as few transition points as possible are formed, which is very favorable with regard to the electrical properties. From a mechanical point of view, there is the advantage that the connection between the wall parts is particularly stable, since the base parts can be plugged into one another over a large area. In addition, the plug-in connections in the connection area of the wall parts with one another and in the connection area between

As can be seen in particular in FIG others forwards the same > The cable connection is of course made in a manner not shown here in such a way that, for example, a clamping device 35 together with the outer conductor of a cable and the corresponding wall part of the socket body results in an outwardly high-frequency connection.

Finally, the antenna socket is still on the receiver side a conventional plastic plate 36, while the additional cover plate 37 is the bankruptcy of a can combination arrangement forms.

the
In a modification of the arrangement shown in FIGS. 1 and 2, it is also possible if the inner conductor of at least one coaxial receiver-side connection is at least partially received in the corresponding pin and partially or completely attached to the first connector 6. The inner conductor of a coaxial receiver-side connection attached to the first Y / andung part 6 can be held in an insulating part that is steeply fastened in the relevant outer conductor socket of the first wall. In this way, both inner conductors of the coaxial connections can also be arranged in., 11eis insulating parts in the interior of the sleeve-like extensions of the outer conductor sockets.
