ABSTRACT:
A front panel for circuit boards e.g. in a telecommunications exchange which plug into connectors attached to a bin, the boards sliding in guides in said bin. Such circuit boards can be difficult to remove from the bin because of multiple contacts in the connectors. The panel is intended to facilitate extraction of its board and comprises a bar of insulative material acting as a stiffener for the board, fitting over the front edge thereof, and an extractor lever articulated to the base of the stiffener bar.
