Thus, a housing plug or a housing socket is provided whose outer conductor is formed only from a relatively thin-walled sleeve, so that only a very small material requirement consists of an electrically highly conductive and preferably no longer necessarily stable material. The majority of the original housing is advantageously by a eige Nes device formed from a simple processable material such as aluminum.

Around to enable a strong and robust contacting force is the outer conductor slidable in the insertion direction or in the direction of the chassis wall arranged.

One embodiment will be explained in more detail with reference to the drawing. Show it:

1 a sectional view through a housing socket,

2 a perspective view of such a housing bushing, which is partially mounted on a Chassiswandung, and

3 one opposite 1 modified housing socket.

How out 1 and 2 can be seen, a preferred housing connector by way of example with reference to a housing socket 1 described. The housing socket 1 essentially has an inner conductor 2 , an outer conductor 3 , one the inner conductor 2 and the outer conductor 3 mutually electrically insulating and spacing insulator 4 and a housing 5 on. These components are preferably arranged cylindrical about a plug-in axis X around.

To attach the housing socket 1 on a chassis wall 6 for example, a radio or a filter, the housing 5 in the direction of the chassis wall 6 a flange 51 on. In the flange 51 is a lot of drilling 52 formed by which screws 53 can be passed to the housing 5 firmly with the chassis wall 6 connect to. Less preferred may alternatively other connection options such as welding or destruction of the housing 5 be used on the chassis wall. The housing socket 1 serves, in the insertion direction X a mating connector, in this case a plug 7 to connect a cable, with the plug 7 in particular an inner conductor 72 and an outer conductor 73 having. In addition, the plug has 7 preferably a thread with which the plug 7 at a thread 51 of the housing 5 is screwed.

For a safe and sufficiently strong and robust contacting force between the outer conductor 3 the housing socket 1 on the one hand and on the other hand the chassis wall 6 to be able to apply as a corresponding mating conductor of the chassis, is the outer conductor 3 in a direction parallel to the plug axis X relative to the housing 5 and additionally or optionally also alternatively relative to the inner conductor 2 slidable in the housing socket 1 arranged. According to various individual embodiments, which are preferably carried out in combination, when mounting the housing 5 on the chassis wall 6 and / or when attaching the plug 7 on the housing socket 1 the outer conductor 3 against the chassis wall 6 pressed.

According to a first preferred embodiment, the housing 5 inside a housing stop 55 on, which towards the side of the housing socket 1 to the chassis wall 6 is formed out. The outer conductor 3 has on the outside according to a housing stop counter stop 35 on which its stop surface from the chassis wall 6 has directed away. To the side of the chassis wall 6 are from the housing stop 55 and from the housing stop counter-stop 35 the housing 5 or the outer conductor 3 formed so far extending that when adjacent housing stop 55 and housing stop counter-stroke 35 the outer conductor 3 to the side of the chassis wall 6 out by a small amount dw from the housing 5 protrudes. This causes when fixing the housing 5 on the chassis wall 6 by means of screws 53 the housing 5 over the housing stop 55 and the housing stop counter-stop 35 the outer conductor 3 firmly against the chassis wall 6 presses or presses and thereby causes a very good contact. However, the decisive contact force is initiated when the mating connector is screwed on.

Additionally or alternatively, a housing length lg is parallel to the plug-in axis X such on an outer conductor length la of the outer conductor 3 matched that when attaching the plug 7 on the housing socket 1 by an inside contacting wall of the plug 7 a the plug 7 facing first outer conductor edge 30 through the plug 7 in the direction of the chassis wall 6 is pressed. It is exploited that, for example, when screwing the plug 7 on a housing thread 54 the outer conductor 3 relative to the housing 5 in the direction of the chassis wall 6 is pressed, the housing 5 in turn stuck to the chassis wall 6 is attached. To implement such an embodiment, the outer conductor length la is preferably longer than the housing length lg, so that the outer conductor 3 on one side or on both sides of the case 5 protrudes. Additionally or alternatively, the location of the housing thread 54 on the housing 5 such on the housing periphery of the housing 5 can be arranged that when engaging a corresponding mating thread of the plug 7 The plug 7 far enough in the case 5 guided or outside on the housing 5 is brought over that the outer conductor 3 by a corresponding counter element of the Ste ckers 7 in the direction of the chassis wall 6 is pressed.

Additionally or alternatively, also a relative movement of the inner conductor 2 to the outer conductor 3 be used to attach the connector 7 on the housing socket 1 by means of the inner conductor 2 and the insulator 4 the outer conductor 3 against the chassis wall 6 to press. According to a first variant, has the outer conductor 3 inside an outer conductor stop 31 on which one way from the chassis wall 6 is formed away. The insulator 4 forms with its outer circumference or with a separate element an outer conductor stop counter-attack 41 off, which is towards the chassis wall 6 or in the direction of the outer conductor stop 31 is directed. In addition, the insulator 4 in an inner conductor insulator receptacle 21 in the direction of the plug-in axis X against displacement with the inner conductor 2 connected. The shift-resistant connection is at least such that with the help of the plug 7 in its attachment to the housing socket 1 a push against the inner conductor 2 the insulator 4 in the direction of the chassis wall 6 presses to over the insulator 4 , the outer conductor stop counter-stroke 41 on the insulator 4 and the outer conductor stop 31 the outer conductor 3 against the chassis wall 6 to press. The dimensioning of the individual components parallel to the plug-in axis X is again such that when mounting, in particular screwing the plug 7 on the housing socket 1 the inner conductor 2 and the insulator 4 the outer conductor 3 relative to the housing 5 in the direction of the chassis wall 6 can press to achieve a very good contact.

According to a variant of this, the insulator 4 in the direction of the plug axis X also completely loose between the inner conductor 2 and the outer conductor 3 or between the outer conductor stop 31 and a corresponding towards the chassis wall 6 directed inner conductor stop be arranged. According to yet another variant, the insulator may also be used 4 and the outer conductor 3 towards at least the chassis wall 6 non-slip interconnected when the inner conductor 2 a corresponding inner conductor stop for pressing the insulator 4 in the direction of the chassis wall 6 having.

Preferably, in such arrangements, the housing 5 as a component, in particular cast component made of aluminum, so that the outer conductor 3 can be manufactured as a simple and substantially sleeve-shaped component with low material costs of a conductive material.

3 shows an alternative embodiment of a housing socket 1* , Compared to the embodiment according to 1 is the housing stop counter-stop 35 of the supervisor 3 so close to one of the chassis wall 6 applied second outer conductor edge 33 arranged that the outer conductor 3 with its second outer conductor edge 33 completely in the case 5 can be pushed into it. Such a variant allows in a first step a very good and completely final fastening the flange 51 of the housing 5 on the chassis wall 6 , In a second step is the plug 7 on the housing socket 1* attached. At the same time the outer conductor becomes 3 with the help of a corresponding section of the plug 7 directed backwards against the chassis wall 6 pressed, with the plug 7 in the direction of the chassis wall 6 against the first outer conductor edge 30 suppressed. By such an arrangement and procedure is a tilted placement of the housing 5 to the chassis wall 6 advantageously avoided if the flange 51 of the housing 5 too rigid to screw on the case 5 because of according to 1 in the direction of the chassis wall 6 protruding outer conductor 3 completely completely against the chassis wall 6 to be bent.

Particularly preferred is an insulating layer 56 . 57 , which on the housing 5 is trained. A in the assembled state of a Chassiswandung facing insulation layer 56 forms an electrical insulation to the chassis wall. One in the assembled state the outer conductor 3 facing insulation layer 57 allows the design with a relation to the outer conductor 3 floating or insulated housing 5 , Particularly preferred is the insulating layer 56 . 57 formed as a hard anodized layer.

In the usual way, variations of the individual components are possible. In particular, instead of plugging the plug 7 and then attaching the plug 7 with a threaded around the plug axis X threaded housing also the entire plug 7 be formed from a single component, so that in such a case under a Aufsteckrichtung at the same time or alternatively a screwing is to be understood.
