Abstract:

One end of a dead front is nested in and covered by a back plate. The end of a cord may be threaded through a hole in the back plate for connection of its conductors to terminal plates housed in the dead front. Integral with the back plate is means for clamping the cord to the back plate thereby to relieve strain on the connections of the conductors to the terminal plates. The hole in the back plate is defined by an area of the back plate which is segmented and thereby made flexible. Within limits, a cord of a diameter larger than that of the normal size of the hole may be accommodated by forcing the same past the segments and thereby enlarging the hole as required for passage of the cord therethrough.
