Comprises at least one fin (5), in which case the first slide-on contact device (6) is formed at the upper end of the first contact member (3) and extends upwardly from the bottom, in this case the first slide. The on-contact device 6 is designed such that the device penetrates through an insulating material which can wrap the outer conductor of the cable to make electrical contact with the outer conductor, and the second slide-on contact device 7 is arranged in a second manner. Formed at the upper end of the contact member 4 and extending upward from the bottom 1, in which case the second slide-on contact device 7 is designed such that the device penetrates the inner cover and forms an electrical contact with the inner conductor.

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 portion 2. The contact portion 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 portion 2 into the insulation portion 3 up to the insulator 3a (which is a part made of Teflon, for example). By the step formation, the position of the contact portion 2 is fixed relative to the insulation portion 3.

In the front view of FIG. 3A, the contact portion 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 a half cylinder jacket, which shields the HF-conductor portion of the contact portion 2 with the HF-plug type connector assembled. Shield.

The insulating displacement contact supports 4a and 4b are preferably provided with four blades 6, respectively, two of 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 U-shaped free end 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 assembling 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 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 present invention is that the blade 6 of the insulation displacement contact supports 4a and 4b can be locked in advance, thereby making assembly low. 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 connector can be used as an inline-coupler plug as well as in a sheet bar using a bent connector 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 that enables a simple assembly and ensures a reliable coupling.
