Description

- 3 - ο ^ ο 1 ° ^η R

The invention relates to coaxial cable connectors, in particular for airfield lighting cables, consisting of a connector or Mating connector sleeve into which a cable with pressed-on contact pin or pressed-on contact sleeve is inserted.

The area of application is the connection of coaxial cables and especially of airfield lighting cables with or without shielding.

In known cable connectors, the assembled cable with a pressed-on contact pin or pressed-on contact sleeve is usually wrapped with a rubber-like plastic made of sulfonated polyethylene (Hypalon; TM from Du Pant), inserted into a plug or mating connector and usually at a temperature of 180 ^° C Vulcanized for 10 minutes. This system applies to cables with or without shielding. This method can only be used to assemble cables insulated with butyl neoprene rubber. Vulcanization can only be carried out in the factory on fixed cable lengths.

According to another method, a plug or mating connector made of Hypalon ^ · 'is pushed onto the assembled cable with the contact pin or contact sleeve pressed on with the aid of silicone grease. The inner diameter of the cable receiving part is slightly smaller than that of the cable. The connector or mating connector exerts a pressure on the cable that ensures a permanent seal that increases the effect of the silicone grease. With this method, however, a differently dimensioned connector or mating connector must be used for each cable type, which can only be used with cables without shielding.

ORIGINAL INSPECTED

The invention is based on the object of eliminating the disadvantages of the known cable connectors, and in particular to enable quick and easy assembly of the coaxial cable connector on the construction site.

To solve this problem, the coaxial cable connector is characterized in that in the rear part of the Connector or mating connector sleeve into which the assembled cable with pressed-on contact pin or pressed-on contact sleeve is inserted, a casting space is formed.

Advantageous developments of the cable connector according to the invention are specified in the subclaims.

The invention is explained below with reference to the drawing. Show it:

1 shows a longitudinal section through a coaxial plug according to the invention with a contact pin;

FIG. 2 shows a longitudinal section through the counterpart according to the invention of the coaxial connector from FIG. 1 a contact sleeve;

3 shows the connection of the cable shield to a ground conductor.

The insulating outer sheath of the cable is in all figures denoted by the reference number 1. This is followed by the cable shield 2, for example made of copper or Brass band and that in the manner shown in FIG. 3 by pressing on a longitudinally slotted sleeve 12 is connected to the earth conductor 10. Does the cable

shielding 2 made of copper wire or a copper wire mesh or a copper wire wrapping, the Connection to the earth conductor 10 by a closed sleeve 12.

The cable shield 2 is separated from the conductor 4 by an insulating jacket 3. Head 4 is either a contact pin 5 (FIG. 1) or a contact sleeve 6 (Fig. 2) pressed on.

That from parts 1 to 5, 10 and 12 (.Fig. 1) or 1 to 4, 6, 10 and 12 (Fig. 2) existing assembled cable is in the rear part of the connector shell 7 (Fig. 1) or the Mating connector sleeve 7 (Fig. 2) inserted. The plug-in parts of the sleeve 7 through which the contact pin 5 or the contact sleeve 6 are pushed, are provided with a projection (Fig. 1) or a correspondingly shaped recess (Fig. 2).

In the rear part of the sheath 7 a grouting 8 is formed, which is tapered towards the plug-in part, so that when the casting compound is introduced (usually a casting resin) To avoid air inclusions. The casting space 8 is delimited at the top in the cylindrical part of the plug by an elongated filling opening 11. This enables a Perfect potting and venting of the cast resin molding material.

The inner surfaces of the potting space are preferably roughened, which ensures good adhesion between the cast Cast resin and the connector shell or the mating connector shell and thus a tight connection is guaranteed.

In the rear part of the sheath 7, a grommet 9 is also attached, through which the cable is passed tightly is. The grommet allows the introduction of cables with different diameters (approx. 10 to 18 mm). The grommet 9 also has a further, initially closed passage for piercing the earth conductor 10.

The insulating jackets 1 and 3 are made of insulating materials that result in tight connections with the potting compounds. For example, the following materials are used: butyl and neoprene rubber, XLPE, PVC and sulfonated Polyethylene (Hypalon). When using insulating jackets made of XLPE, a tight connection between Cast resin molding material and insulating jacket achieved with the help of a self-amalgamating tape. With the other cable sheaths perfect adhesion of the casting resin to the jackets is guaranteed without special precautions.

As shield 3, copper or brass tape or copper wire mesh can be used or copper wire wrapping can be used.

The cable connectors according to the invention have the advantage that they can be installed quickly and easily on the construction site and are versatile. In particular

place

the cable connectors according to the invention are used in flight lighting cables used with or without shielding with success. For example, the cable connector according to the invention for an airport lighting cable with the following characteristics can be used: cross section 6 mm2 / AWG 8; Voltage up to 5 kV; Regulation FAA-L-823.
