Abstract

A splicing device for connecting two electrical cables by forming a splice, each electrical cable including a sheath, a cladding and at least a first primary wire and a second primary wire. The cladding is surrounded by the sheath and surrounds the at least two primary wires. The splicing device includes a first electrical connector for connecting together the first primary wires of the two electric cables, and a second electrical connector for connecting together the second primary wires of the two electric cables. The splicing device further includes a first insulating sheath for covering the first electrical connector of the first primary wires, the first insulating sheath being made of a first material, and a second insulating sheath separated from the first insulating sheath for covering the second electrical connector of the second primary wires, the second insulating sheath being made of the first material. A holder is provided to maintain the first and second insulating sheaths in a constant relative position. The holder is made of a second material. The first and second materials and the thickness of the first and second sheaths and of the holder are chosen so that the characteristic impedance between the first and second electrical connectors of the splice is substantially equal to the characteristic impedance of each electrical cable. A continuity assembly is also provided for electrical continuity of the cladding.
