## Abstract

In a weapon system having a recoiling component, recoil-free component, a first electronic system disposed on the recoiling component, a second electronic system disposed on the recoil-free component, a trailing cable is continuously electrically connected between the first and second electronic systems. A tension-relieving mechanism is coupled between the recoiling component and the recoil-free component in a substantially tension free manner and mounts the trailing cable such that the trailing cable is substantially free of tension. The tension relieving mechanism is mounted in a resilient manner on the recoiling component of the weapon system.

## Claims

### Claim 1

In a weapon system having a recoiling component and a recoil-free component, with a first electronic system disposed on the recoiling component, a second electronic system disposed on the recoil-free component and electrical communication means arranged for communicating signals between the first and second electronic systems, the improvement wherein said electrical communication means comprises:
a trailing cable continuously electrically connected between said first and second electronic systems;
a tension-relieving mechanism comprising a chain, said tension relieving mechanism being coupled between the recoiling component and the recoil-free component in a substantially tension free manner and mounting said trailing cable such that said trailing cable is substantially free of tension; and
mounting means for mounting said tension relieving mechanism in a resilient manner on the recoiling component of the weapon system.

### Claim 2 (depends on 1)

The system of claim 1, wherein said chain is comprised of chain links.

### Claim 3

In a weapon system having a recoiling component and a recoil-free component, with a first electronic system disposed on the recoiling component, a second electronic system disposed on the recoil-free component and electrical communication means arranged for communicating signals between the first and second electronic systems, wherein said recoiling component comprises a breech ring of a gun barrel and said recoil-free component comprises a cradle supporting the gun barrel, and wherein said electrical communication means comprises:
a trailing cable continuously electrically connected between said first and second electronic systems;
a tension-relieving mechanism coupled between the recoiling component and the recoil-free component in a substantially tension free manner and mounting said trailing cable such that said trailing cable is substantially free of tension; and
mounting means for mounting said tension relieving mechanism in a resilient manner on the recoiling component of the weapon system.
