Description

The present invention relates to connectors for coaxial cables

  especially for aerodrome beacon cables comprising respectively a male plug body or casing and a female plug body or casing in which a cable is slid with respectively a crimped pin and socket. The scope is connection

  coaxial cables and especially beacon cables for aerodromes, shielded or not.

  In known cable connectors, the born infection cabinet, comprising a crimped pin or socket, is usually wrapped by a synthetic material such as rubber, in dark polyethylene (Hypalon; brand of the Du Pont firm), is introduced into a male plug or female plug mold and is generally vulcanized at a temperature of 80 ° C for 10 minutes This system is used for shielded or unshielded cables According to this process, only sands isolated with butyl neopran rubber can be used Vulcanization cannot take place

  only in the workshop and on specific cable lengths.

  According to another method, on the cable made up with a crimped contact pin or a

  socket set, a male plug or a female 25 Hypalon plug is slipped with silicone grease.

  The internal diameters of the cable receiving element are a little smaller than that of the cable. Therefore the male plug or the female plug exerts on the cable a pressure which ensures a permanent seal which further reinforces the effect of the grease of silicone. In this process, however, 5 must be used for each type of cable a male plug or a female plug having a different dimension which cannot be

  used only for unshielded cables.

  The problem which is the basis of the invention is to remedy the drawbacks of known connectors and especially to allow rapid assembly.

  and simple of the coaxial connector on site.

  For the solution of this problem, the coaxial connector is characterized in that in the rear part of each plug body, in which the finished cable is slid 15 with respectively the pin or the

  socket, a space or a casting chamber is formed.

  In order to clearly understand the invention, a non-limitative embodiment will be described below, with reference to the drawings in which: FIG. 1 is a longitudinal section through a coaxial connector according to the invention

including a contact pin.

  Figure 2 is a longitudinal section at

  through the opposite element of the coaxial connector of Figure 1 comprising a contact sleeve.

  Figure 3 shows the shield connection with

a ground wire.

  In all the figures, the insulating sheath of the cable is designated by the reference 1 To this sheath is added the shield 2 of the cable which, for example, is formed by a ribbon of copper or brass and which in the example represented by FIG. 3 is connected to the ground wire 10 by crimping a sleeve 12 provided with a cutout or longitudinal slot If the shield 35 2 is made of copper wire or consists of a braid of copper wire, the connection with the wire Earth

  is carried out by means of a closed sleeve 12.

  The shield 2 is separated from the conductor 4 by an insulating sheath 3 On the conductor 4 is crimped a contact pin 5 or a contact socket 6 (FIG. 2). The finished cable formed of elements 1 to 5, and 12 (figure 1) or 1-4, 6, 10 and 12 (figure 2) is slid into the rear part of one of the bodies 7 of the 10 connector Body parts 7 through which the contact pin 5 or the sleeve 6 is slid, are provided with a projection (FIG. 1) or with a

  hollow having a corresponding shape (Figure 2).

  In the rear part of the body 7 is formed a casting chamber 8 which, towards the connection element, has a conical shape in order to avoid air inclusions during the introduction of the casting mass (generally a casting resin) The chamber 8 is delimited upwards in the cylindrical part of the connector by a longitudinal opening 11 for filling This opening allows a faultless casting

  and deaeration of the casting material.

  The interior surfaces of the casting chamber are preferably roughened to give good adhesion between the resin and

  envelopes and thus obtain a good seal.

  In the rear part of the body of the connector is further provided a plug 9 through which the cable is introduced in a leaktight manner The plug 30 allows the introduction of cables having different diameters (about 10 to 18 mm) The plug 9 has further another entry which the sinking of the wire

earth 10.

  The sheaths 1 and 3 are made of insulating materials which allow a tight connection with the casting masses. As examples, the following materials can be used: butyl rubber and neoprene, PRC (crosslinked polyethylene), PVC and polyethylene sulfonated (Hypalon). When using PRC insulating sheaths, a tight connection is obtained between the casting resin and the insulating sheath by means of a self-vulcanizing strip. In the case of other sheaths, adhesion

  satisfactory resin on the envelopes is ensured.

  As shield 3 you can use a copper strip or a brass strip or a wire braid

of copper.

  The connectors according to the invention have the advantage that they can be mounted quickly and in a simple manner on the site with multiple applications. Especially in the case of beacon cables

  for aerodromes with or without shielding, the connectors 20 according to the invention can be successfully installed.

  For example, the connector according to the invention can be used for a beacon cable having the following characteristics: section 6 mm 2 / AWG 8; voltage up to 5 k V; prescription FAA-L-823. 25
