Description

The invention relates to an electrical connector with a connector for connecting the braided outer conductor of a coaxial cable, which separates the inner conductor from the outer conductor Comprises dielectric, the terminal portion having a generally U-shaped ferrule with a pair side walls arranged at a distance from one another and connected to one another by a bottom part and a pair of lancet-like projections for contacting the interior of the ferrule with the outer cable conductor.

In a known connector of the type mentioned (DT-OS 15 15 421), the lancet-like Projections formed from the bottom part of the ferrule and extend in the longitudinal direction of the Clamp at a distance from each other and parallel to the associated side walls. When inserting a Coaxial cable into the ferrule, the lancet-like projections pierce the outer insulation of the cable and lie against the side of the outer cable conductor and are then pressed on when the clamp is pressed printed on the cable against the outer conductor.

It is also known (US-PS 27 59 161), electrical contact with the conductive core of an isolated line. ! ites to be produced by means of a lancet-like projection that insulates the conductor wire penetrates and penetrates into the one-piece or stranded conductive core of the wire.

The object of the invention is to provide an electrical <*> To create a connector of the type mentioned, in which an improved electrical contact of the lancet-like Projections with the outer cable conductor is achieved.

This object is achieved according to the invention in that each lancet-like projection consists of a side wall is formed and with respect to the side wall at an acute angle inward extends away from the bottom part and that the lancet-like projections are arranged directly opposite one another and when the ferrule is pressed against the coaxial cable, each lancet-like projection is between penetrates the strands of the outer cable conductor and some of the strands between the lancet-like projection and the inner surface of the associated side wall are compressed.

In the connector according to the invention, by catching some strands of the braided outer conductor between each lancet-like projection and the associated side wall of the ferrule achieved that the trapped strands are pressed under pressure against the lancet-like projections and thereby a good electrical connection is obtained, even when passing through different temperature ranges and intensive steam treatment remains stable

An embodiment of the invention is described below with reference to the figures. From the figures shows

F i g. 1 is a top plan view of an electrical connector connected to the end of a coaxial cable.

2 shows a section along the line II-II of

Fig.1.

F i g. 3 one of the F i g. 2, the configuration of a clamp before pressing is shown; and

F i g. 4 is a diagrammatic perspective illustration showing the connection of the ferrule to the outer conductor of the coaxial cable illustrated.

A coaxial cable 1 has an inner conductor 3, a the Inner conductor 3 from a braided outer conductor 7 separating dielectric 5 and an insulating outer sheath 9 on. F i g. 1 shows an electrical connector 10 connected to one end of the coaxial cable 1 is. The connector 10 has a first contact member 12 and one which is spaced apart therefrom second contact member 14. Each contact member 12, 14 has a contact part in the form of a pin 16, 18 and a ferrule 20, 22. As in FIG. As best shown in Fig. 1, the pins 16, 18 are laterally offset with respect to one another arranged, and the ferrules 20, 22 are spaced from each other coaxially aligned with each other. the Ferrule 20 is generally U-shaped in cross-section, with the sides of the U formed with dragon-tooth teeth are. The clamp 20 is shown in FIG. 1 pressed around the inner conductor 3, which was previously used for preparation of the pressing step was exposed.

The ferrule 22 is generally U-shaped in cross section with a pair of side walls 24, 26 extending over a curved bottom part 28 are connected to one another. A lancet-like projection 30, 32 extends extending from each side wall 24, 26, the projections 30. 32 being arranged opposite one another are. When the ferrule 22 is pressed against the coaxial cable 1, the lancet-like projections penetrate 30, 32 the insulating outer sheath 9 and the strands of the braided outer conductor 7, whereby some of the strands are compressed between a lancet-like projection and the inner surface of the ferrule 22 will. Like F i g. 2 shows is between the projections 30, 32 after the pressing operation there is sufficient clearance so that the inner conductor 3 and the dielectric 5 are between the can extend through lancet-like projections. The pressure connection results in the Litz wires of the braided outer conductor 7 are pressed against each lanzettenart.gen projection 30, 32 under pressure

thereby creating a good stable electrical connection while passing through different Temperature ranges and the accelerated passage of moist heat results.

The side walls 24, 26 are pressed against the insulating outer sheath 9 and thereby support the mechanical retention of the Kor.takt linkes 14 on the cable 1.
