Telecommunications cable splice closures
First Claim
1. A telecommunications cable having a plurality of insulated conductors and a splice closure comprising at least two insulated conductors which are severed at the splice to electrically disconnect first parts of these conductors extending from the splice region in one axial direction from second parts extending in the other axial direction, each of said first parts provided to have an electrical connection to an insulated conductor of another cable, a closure around the cable splice region to prevent moisture access to the inside of the cable or to bared electrical conductors at the connection, and a plurality of electrical conductor windings providing a coil which is electrically connected between and in series with said second conductor parts.

Abstract
Telecommunications cable with a splice closure covering conductors which have been severed and each having one severed end electrically connected to another cable. The other severed ends of the conductors are placed in series with a coil formed of electrical windings to enable a current to be passed through the coil by passing it through the electrically "dead" parts of the conductors to create an electromagnetic field around the coil to indicate the splice position. Preferably, the coil is formed by windings passing around the cable and these windings may be embedded in the closure.

5. A method of making a splice closure in a telecommunications cable comprising:
selecting two insulated conductors of the core of the cable and severing the conductors at a splice region to electrically disconnect first parts of these conductors extending from the splice region in one axial direction from second parts extending in the opposite axial direction;
electrically connecting in series between the second conductor parts, a plurality of electrical conductor windings to provide a coil between said second parts, the first conductor parts provided for electrical connection to an insulated conductor of another cable; and
forming a closure around the splice region either before or after connecting the coil in series with the second conductor parts.- View Dependent Claims (6, 7, 8)
