Definitions

  • the present invention relates to apparatus for use in telecommunications systems.
  • the surge protector has therefore been removed from the installation in order to allow testing.
  • Surge protectors are small items, usually not much greater than 1 cm in length, and if removed in large quantities at the top of a telegraph pole are apt to be lost. Installation engineers are also liable to forget to replace them. This means that the cable can be left unprotected.
  • isolators consisting of an elongate strip of polymeric insulation material which sat between the electrical contacts and around the surge protector.
  • installation engineers then failed to notice the isolator and left it in place, again leaving the line unprotected.
  • the present invention therefore provides a surge protection apparatus for a telecommunications circuit comprising a surge protector and a pair of electrical contacts adapted to connect the surge protector to the telecommunications circuit, the apparatus including an external closure enclosing the surge protector and the contacts thereto, wherein an isolator is provided in the form of a piece of insulating material placed between the contacts having a gripping portion extending to a region outside the closure thereby to aid identification and removal of the isolator.
  • the isolator is in the form of an elongate strip of insulating material formed into a U shape, the ends thereof projecting between the contacts and the middle thereof being situated outside the closure and providing the gripping portion.
  • the isolator projects through apertures formed in the closure.
  • closure and the isolator are formed in contrasting colours, so that it is clear to an operator that the isolator is still present.
  • the isolator is a brighter colour than the closure, therefore tending to draw the eye towards the isolator.
  • FIG. 1 shows a pole top distribution point 10 in the form of a ten-pair terminal unit.
  • An incoming exchange wire 12 passes through an aperture 14 in a wall of the unit 10 and is held by a cord grip 16 before being divided to lead to one of ten terminal points 18 arranged in two side-by-side rows of five.
  • These terminal points 18 comprise a pair of bores 20 facing outwardly thereof and a bolt head 22 on a top surface thereof, rotation of which causes the terminal unit 18 to raise and lower itself relative to a pair of IDC connectors (not visible).
  • a consumer wire placed in a bore 20 is inserted into the IDC unit.
  • a fuller description of the terminal block can be found in our earlier Patent Applications GB-A-2129630 and GB-A-2176062.
  • Each terminal unit 18 has a barrel-shaped compartment 24 in which is situated a surge protector 26. This is visible more clearly in Figure 2 in which the lid 28 of one compartment 24 has been removed to reveal the surge protector 26. This has three contacts, being a disc-shaped contact 30 at either end thereof and a ring-shaped contact 32 about the middle of the cylindrical protector 26. The end contacts 30 are connected to the incoming exchange wires via sprung contacts 34 and the central contact 32 is connected to earth via earth clip 36. This arrangement is described in more detail in our Application No. GB-A-2176062 mentioned above.
  • each cap 28 is formed with a pair of apertures 38. These are visible on the compartment 24 of Figure 1 from which an isolator has been removed.
  • the isolator 40 comprises a substantially U-shaped elongate strip of plastics insulator material, the spacing between the legs being approximately equal to the spacing between the apertures 38 on the cap 28.
  • the isolator can therefore be inserted through the cap with its legs passing through the apertures 38, and will occupy the position shown in Figure 3.
  • the cap 28 has been omitted for clarity, but it should be understood that an important feature of the invention is that the isolator 40 extends from outside the compartment 24 to inside.
  • the ends 42 of the legs of the isolator 40 lie between the disc contacts 30 of the surge protector 26 and the contacts 34 connecting same to the telephone lines, as shown in Figure 3. Thus, the surge protector 26 is disconnected.
  • the terminal unit 10 can be supplied in the forms as substantially shown in Figure 1, i.e. with isolators 40 present on each terminal 18 ensuring that all surge protectors 26 are isolated. It can then be installed and tested. Once testing is complete and successful, the isolators 40 are clearly visible and obvious and can be removed by an engineer.
  • the usual colour for terminal units is black, and therefore a preferred colour for the isolators 40 is yellow or a similarly bright and obvious colour.
  • the interior of the compartment 24 is normally filled with a grease or gel based sealant material 44.
  • the contacts 34 will move to make electrical contact with the disc contacts of the surge protector 26, and the entire arrangement will remain under cover of the sealant 44. It will not be necessary for the engineer to interfere with the sealant, and no path will be available for moisture to reach any contact. Meanwhile, the presence of the isolator is immediately obvious and apparent to the engineer.
