DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an HF (high frequency) plug connector system, and more particularly to an HF plug connector used in an automobile and a method of assembling the HF plug connector system.

[0002]

2. Description of the Related Art The connector system known from the prior art for two HF cables consists of a metal plug connector which incurs a considerable assembly cost for use. The cables to be joined must have the insulating coating removed three times, the cables must be abutted against each other, the inner conductors must be brazed to each other, the outer conductors must be flanged,
The cable must be inserted through the plug connector casing and finally be contacted by the introduction of a holding element.

A further connector for a coaxial cable is known from DE 3688284, which is shown in FIGS. 1 and 2 attached hereto. ing. Next, a known connector will be described with reference to FIGS. The illustrated connector comprises a bottom part 1 made of an electrically insulating material, contact elements 3 and 4 mounted on the bottom part and having a contact type contact device 6 and 7, and a cap-shaped mounting made of an electrically insulating material. And the mounting portion surrounds the cover-type contact devices 6, 7 when combined with the bottom portion 1, and the cap-shaped mounting portion 2 receives the cable end. And a slit 14 for receiving said mating contact device 6, 7, said gap having a curved inner surface 9, 10, 13, 12; The first contact element 3 and the second contact element 4 are electrically disconnected, and extend parallel to each other upward from the bottom portion 1 and perpendicular to the bottom portion. The first and second contact elements 3 and 4 each have at least one pin 5 at one end, and the pin projects downward through the bottom of the bottom portion 1. In this case, the first push-fitting contact device 6 is formed at the upper end of the first contact element 3 and extends upward from the bottom portion 1. Is designed to penetrate all the insulating material surrounding the outer conductor and make electrical contact with the outer conductor, and the second mating contact device 7 is provided at the upper end of the second contact element 4. Formed on the bottom portion and extending upward from the bottom portion 1, and furthermore, the second cover-type contact device 7 is designed to penetrate the inner insulating layer and make electrical contact with the inner conductor. . In this case, the cap-shaped mounting part has four curved inner surfaces 9, 10, 13, 12 which are spaced apart in the longitudinal direction of the cable, each inner surface having a U-shaped cross section. And the curved portion of the first inner surface 9 and the curved portion of the fourth inner surface 12 face the bottom portion 1 and
The curved portion of the inner surface 10 and the curved portion of the third inner surface 13 face the direction away from the bottom portion 1. In this case, the bottom part 1 has a separate curved surface 8 and, together with the curved part of the first inner surface 9, forms a completely circumferentially extending interference seat as a bearing for the cable. The diameter of the gap formed by the first inner surface 9 and the second inner surface 10 is substantially equal to the diameter of the gap formed by the third inner surface 13 and the fourth inner surface 12; The diameter of the gap formed by the inner surface 13 and the fourth inner surface 12 of the cable is such that the gap formed by the first inner surface 9 and the second inner surface 10 can better support different exposed portions of the cable. Is designed to be substantially equal to or smaller than the diameter of The cap-shaped mounting portion 2 is completely detachable to facilitate insertion of the cable end.

In the case of this prior art as well, a number of assembly steps are required, and the operation of removing the insulation of the outer coating layer is absolutely indispensable and complicated.

[0005] In short, the disadvantages of the known connectors for HF cables are that an excessively large number of assembly steps are required, and the complete insulation removal of the coaxial cable is considerably more time-consuming, for example due to shielding damage due to insulation removal of the outer sheath layer.

For this purpose, the insulation of the HF cable 1 is removed in the end region, so that the HF conductor 1a is exposed over a suitable length corresponding to the holding section 2a of the contact part 2. According to the sectional view shown in FIG. 3C, the contact portion 2 has a stepped shape. The stepped shape serves to insert the contact portion 2 into the insulator 3a up to the insulator 3a (for example, a component made of Teflon). With this step shape, the position of the contact portion 2 is positioned relatively to the insulating portion 3.

The front view (A) of FIG. 3 shows the contact portion 2 having a three-bladed structure. A first cutter-type clamp contact holder 4a is provided above the HF cable 1;
A second cutter-type clamp contact holder 4b is disposed below the F cable 1, and a semi-cylindrical shield plate 10 is provided on each of the cutter-type clamp contact holders 4a and 4b. The shield plate is in contact state 2 when the HF plug connector is assembled.

The HF cable 1 is in contact with the HF cable 1 in an assembled state. By subsequently pressing or pressing the two cutter-type clamp contact holders 4a and 4b,
The two free ends of the U-shape first cut the outer insulation layer of the HF cable by shifting linearly towards the center of the HF cable.

A locking element 8 is provided in the region of the U-shaped base section of the cutting blade 6, the use of which will be explained later.

An intermediate casing 5 is arranged for guiding and holding the two cutter clamp contact holders 4a and 4b (see FIG. 4), which surrounds the two cutter clamp contact holders 4a and 4b. On the inner surface side of the intermediate casing 5, a plurality of U-shaped concave portions 5a are provided.

Are crimped between the pair of cutting blades 6 facing each other. Cold welding is performed between the cutting edge 6 and the wire mesh of the outer conductor. In that case, the shielding action of the HF cable is transmitted to the shield plate 10 via a conductive connection.

FIG. 6 shows a state after the outer casing 7 has been assembled. Particularly preferably, the dividing line 7a
The two-part plastic outer casing 7, which is divided in two along the top, is placed over the intermediate casing 5 and is positioned by pressing the two casing halves (particularly by engagement).

Since the HF plug connector system described above is preferentially adopted especially in the field of automobiles, the outer casing 7 made of plastic can have a special sign (for example, a color code) for facilitating use.

A further advantage of the HF plug connector system according to the invention is that the cutting blades 6 of the two-cutter clamp contact holders 4a and 4b can be pre-locked, which results in a reasonable assembly cost. You can see. In order to position the HF plug connector system, ie the outer casing 7, in a later peripheral structure, a locking mechanism 11 with a button for releasing the connection is advantageously provided.

Since the HF plug connector system described above consists for the most part of plastic parts, a weight reduction is obtained in comparison with the prior art and only a very small structural volume is required. The size of the outer casing in this embodiment is about 13.45 × 14.09 × 18.61 mm.
It is.

The individual parts of the HF plug connector system can be manufactured inexpensively by plastic injection molding and using simple bend-punched parts.

As can be seen from the front view (A) of FIG. 6, it is possible to provide the outer casing 7 with a cord portion 12 for eliminating erroneous connection for a unique arrangement of the plug connector.

The plug connector system proposed by the present invention can be used both as an in-line mating plug and as an angle plug connector for making direct contact connection to a blank.

Finally, it is also possible to form multi-pole plug connectors for HF cables, in which case a plurality of HF plug connector systems are arranged in a common housing.
