The invention is described in detail below with reference to the preferred embodiments.

As can be seen from Fig. 3 (c), the free end of the HF-conductor 1a of one HF-line 1 is preferably contacted by crimping (alternatively by soldering or the like). Is fixed. For this purpose the end region of the HF-line 1 is naked insulated, whereby the HF-conductor 1a is freely arranged in a suitable length corresponding to the supporting section 2a of the contact 2. The contact part 2 is formed in the form of a staircase when viewed in cross section according to FIG. 3 (c). This staircase is used to insert the contact 2 into the insulation 3 up to the insulator 3a (which is a part made of Teflon, for example). The position of the stepped contact 2 is fixed relative to the insulation 3.

In the front view of FIG. 3 (a), the contact part 2 is shown in three wing shapes. A first insulation displacement contact support 4a is disposed above the HF-line 1, and a second insulation displacement contact support 4b is disposed below the HF-line 1, in which case two insulation displacements are provided. The contact supports 4a and 4b are each provided with a shield plate 10 in the form of one half cylinder jacket, which shields the HF-conductor portion of the contact 2 with the HF-plug type connector assembled. .

The insulating displacement contact supports 4a and 4b are preferably provided with four blades 6, respectively, two of which are each side with respect to the axis of the HF-line 1 as shown in FIG. 3 (b). Shown in the figure. The blade 6 is formed in a hemispherical shape when viewed in cross section as can be seen in FIG. 3 (d), and the free end of the U shape is assembled with the HF-line 1 in a preassembled state. Later, when the insulation displacement contact supports 4a and 4b are pressed or pushed, ie moved linearly in the direction of the center of the HF-line, the U-shaped free end first cuts the outer insulator of the HF-line.

Within the U-shaped base section region of the blade 6 a locking member 8 is provided, the use of which is described below.

In order to guide and support the insulation displacement contact supports 4a and 4b, an intermediate housing 5 surrounding the insulation displacement contact supports 4a and 4b is arranged (see FIG. 4). Inside the intermediate housing 5 is formed a U-shaped groove 5a for accommodating the blade 6 and guiding the blade.

The intermediate housing in the region of the U-shaped groove 5a is provided with a plurality of locking openings 9 which are linearly continuous in the guide direction, which cooperates with the locking member 8 of the blade 6. In the assembled state shown in FIG. 4 (see FIG. 4 (d)), the locking member 8 of the blade 6 is engaged with the outer locking opening 9 of the intermediate housing 5.

By pressing in or pressing the insulation displacement contact supports 4a and 4b relative to the intermediate housing 5, the blade 6 cuts inside the HF-line 1 and penetrates through the outer insulator. By locking the locking member 8 into the inner locking opening 9 of the intermediate housing 5, the position of the insulation displacement contact supports 4a and 4b is protected. This state is shown in Fig. 5 (d).

The blade 6 then cuts the insulator of the HF-line 1, and the outer conductor of the HF-line 1 is pressed between the blades 6 facing in pairs. Cold welding is made between the wire mesh of the outer conductor and the blade 6. The shielding action of the HF-line is transmitted on the shielding plate 10 via conductive coupling.

Since the HF-plug type connector described so far is preferably used in the automotive field, the plastic outer housing 7 can have special advantages (eg color coding) to facilitate its use.

Another advantage of the HF-plug type connector according to the invention is that the blade 6 of the insulation displacement contact supports 4a and 4b can be pre-locked, making assembly cheap. In order to fix the connector, ie the outer housing 7 around its latter, a locking part 11 is provided which preferably comprises one key for disengaging the coupling.

Since the aforementioned HF-connectors are mostly made of plastic parts, the weight is reduced compared to the prior art, and the connectors require very little installation space. In an embodiment the dimension of the outer housing is about 13.45 x 14.09 x 18.61 mm.

Individual parts of the HF-connector can be manufactured inexpensively by plastic injection molding and by simple cutting and bending parts.

In order to clearly assign the connector, the outer housing 7 may be provided with a coding 12 (see FIG. 6) that eliminates error coupling.

The aforementioned connectors can be used as inline-coupler plugs as well as in sheet bars using bent connectors for direct contact.

Finally, multipolar HF-line-couplings are also feasible, in which case multiple HF-connectors are arranged in one common housing.

According to the present invention, it is possible to provide an HF-plug type connector which enables a maximal simple assembly while ensuring a reliable coupling.
