Patent number: 9426843Abstract: An electrical raft (200) is provided that has electrical conductors (252) embedded in a rigid material (220). The electrical raft is provided with an electrical connector (700). The electrical connector (700) is mounted in the electrical raft (200) at a mounting angle (730). The mounting angle is set such that the electrical conductors (252) can be connected to the electrical connector without having to turn through an angle or a radius of curvature that would subject them to excessive bending stress. Similarly, the mounting angle means that any conductors (766) that may be connected to the electrical connector (700) do not have to turn through an angle or a radius of curvature that would subject them to excessive bending stress. Furthermore, mounting the electrical connector (700) at the mounting angle (730) may allow the assembled electrical raft (200) to be more compact.Type: GrantFiled: December 17, 2012Date of Patent: August 23, 2016Assignee: ROLLS-ROYCE plcInventors: Michael Christopher Willmot, Matthew Peter Fitt, Philip Summerfield, Paul Broughton, Richard Peace, Gary Alan Skinner, Robin Charles Kennea
