摘要： An end connector for a fibre optic micro duct includes a hollow housing. The housing is open at one end and includes a connector 2,3 to connect to the end of the micro duct. A flow path extends through the end connector and a pressure sensitive valve 5 is in a second end of the housing opposite to the first end. The pressure sensitive valve 5 is biased closed blocking the flow path through the end connector when the pressure at the first end is below a threshold value. The valve opens allowing gas to flow through the end connector when the pressure at the first end exceeds a threshold value. Installing an optical fibre within a building includes running a micro duct from a duct at one end of the micro duct, to a building at the opposite end of the micro duct where the micro duct terminates. This end connector is fitted at the opposite end of the micro duct within the building. An optical fibre or optical fibre bundle is blown from one end to the opposite end of the micro duct using a blowing pressure sufficient to open the pressure sensitive valve within the end connector.

摘要： A fibre optic cable connector comprising a connector body 1 with an axial through bore having a connector 2 at either end for the connection of a respective tube. An annular flange 20 extends radially into the through bore, each end face of the annular flange providing a stop surface for a respective tube end. The annular flange is undercut 21 such that it is inclined so that the axial dimension of the flange increases towards the axis. A plurality of axial splines 30 on the wall of the through bore in the vicinity of the annular flange deflect the outer wall of the tube as it approaches the flange. The interface with the annular flange and the connector body may be radiused to provide a curved transition

摘要： A fibre optic cable connector comprising a body 1 made of a plastic, defining a through bore and having a connector 2 at either end for connection to a respective tube. The body has an outer sleeve 5 and an inner sleeve 6 configured to receive the distal end of a respective tube. The inner sleeve is spaced from the outer sleeve to define an air gap 12. The inner sleeve is supported on the outer sleeve by at least one discrete web 7 of material, which maintains the air gap. The outer face of the connector body 1 is devoid of ribs and the connector body id made of a non-opaque plastic. There may be more than one web and they may be angularly offset from one another.

摘要： A reducing fibre optic cable tube connector with a plastic body having a connector at either end for connection to a respective tube T. The body has a wide portion 4 terminating at a wide end and a narrow portion 5 terminating at a narrow end to receive tubes of a different diameters. The two portions meet at a central region of the body. Each portion comprises an annular inner sleeve 14, 19 extending from the central region and spaced from an inner wall of the outer body to define an air gap 15, 21. Wherein at the central region the annular sleeves 14, 19 extend towards one another such that the first and second air gaps 15, 21 are axially spaced by less than 1mm.

摘要： A fibre optic cable connector comprising a connector body (1) with an axial through bore (8) having a connector (2) at either end for the connection of a respective tube. An annular flange (20) extends radially into the through bore, each end face of the annular flange providing a stop surface for a respective tube end. The annular flange is undercut (21) such that it is inclined so that the axial dimension of the flange increases towards the axis. A plurality of axial splines (30) on the wall of the through bore in the vicinity of the annular flange deflect the outer wall of the tube as it approaches the flange.

摘要： A pipe connector comprising a hollow body having a central throughway defining an axis, the body comprising a tubular part 11 at at least one end, the tubular part having a groove retaining an elastically deformable sealing ring 2 on an outer face to seal, in use, with an inner diameter of a tube placed over the tubular part; a collet 3 fitted over the tubular part of the body so as to be axially fixed with respect to the body and being spaced from the tubular part to form a cavity for the tube, the inner face of the collet having at least one tooth to grip the tube, in use, and the outer face of the collet having a first screw thread; and a locking cap fitted over the collet and having an inner face with a second screw thread which is complementary to the first screw thread, wherein screwing the locking cap onto the collet from an unlocked configuration to a locked configuration causes inward deflection of the collet to press in use, the collet onto the pipe and the pipe onto the sealing ring to seal the interface between the body and the pipe.
