DE2330149A1 - Communications cable lead junction box - has clamp and sealing system extending lead junction box collars on either side - Google Patents

Abstract

The lead colar has two halves connected together and sealed by flanges. Each half outer end is stepped down and threaded on its outer surface to allow a threaded tube to screw over it. The tube is sealed to the collar half at the bottom of the thread. The tube outer end has an external thread to accept a cover cap with a central hole for the plastics cable. The conducting part of the cable passes straight through the tube into the junction region enclosed by the collar halves, whilst the cable insulating sleeve is clamped between serrations on the outer surface of the double stepped end of the collar and the inside of the tube. Two elastic sealing washers are located in the cap neck.

Description

Lengthways or crosswise split connection or branch socket made of lead

The patent or utility model auxiliary application with the above designation from June 5, 1973, e: "a cable clamping and sealing system under protection, in which, according to claim 2, the part of the clamping and sealing system facing the soldered sleeve is connected to this firmly and preferably by soldering. That assumes that this is the case is two initially separate parts. But there is no absolute necessity for this.

According to the present claimed additional patent, the approach initially accessible from the outside, which is expediently provided with a toothing, and an existing metallic cable shield and the outer plastic jacket layer

of the cable with the help of a clamp, be part of the socket neck or by soldering or embedding in the socket neck to form a whole with the socket.

This saves a component of the system, there now the pipe socket with the shoulder attachment can be connected directly to the socket neck.

According to the extended conception, a disk can be embedded in this shoulder approach The inner diameter is adapted to the outer cable sheath diameter in a manner known per se. These Disc forms a cavity in connection with a second disc, which is pretreated in the same way

for receiving a seal, with a central pressure on this seal by means of a union nut is exercised in the axial direction. This type of seal gives a much better result than a known sealing pressing, in which two half-shells are pressed against the sealing material will.

Such a design is preferably provided especially for transversely divided sleeves. The attached drawing shows one such in longitudinal section, the sleeve half (1) with the sleeve half (2) by screw connections at 3 is connected using a roll or pinch seal (4). Each half of the socket ends at the neck with a toothed extension (5) »on which the cable sheath in the manner already shown is fastened with the pipe clamp. The pipe sleeve (6) then connected to the cable sleeve half is shielded the cable fastening using a seal (7) to the outside, forms the clamping space (8) and takes on the sealing support disc (1O), xiie later against the shoulder piece of the pipe socket (6) is pressed with the inclusion of the seal (11). Another seal support washer (1O) is housed in the union nut (9) and is tightened in the axial direction by tightening the Union nut pressed tightly against the seal housed in the cavity (12).

Claims (3)

Claims .1 longitudinally or transversely divided connection or branch sleeve made of lead, preferably determined for communication cable systems, characterized in that the approach accessible from the outside, the expedient is to be provided with a toothing and on which an existing metallic cable shield and the outer plastic jacket layer of the cable, is part of the sleeve neck or by soldering, press-fitting or by some other fastening with the sleeve forms a whole. 2. Longitudinally or transversely divided connection or branch sleeve made of lead, preferably determined for communication cable systems according to claim 1, characterized in that the cable outlet seal is effected by two sealing washers which compress the sealing compound in the axial direction by means of a union nut. 3. Longitudinally or transversely divided connection or branch sleeve made of lead, preferably determined for communication cable systems according to Claims 1 and 2, characterized in that for the outlet of two cables in the same direction from the sleeve of the sleeve neck with two toothed lugs is provided for cable attachment. 409881/0671 Blank page
