Abstract

Printed circuit boards containing integrated circuits are subject to damage from electrostatic discharge (ESD). Because of this, it has been the practice to ship circuit boards in conductive packages. In order to prevent inadvertent opening of a conductive box containing an electronic circuit board, the box 10 (Figs. 1 and 2) locks when the top lid 11 is closed. The circuit board nests in a cavity 15 situated between anti-static foam elements 16 and 17. A flexible latch 20 is attached to the top cover 11 or integral therewith and is positioned to cooperate with a cam 25 fixed to a wall 13.

Integral Interior Latch

Printed circuit boards containing integrated circuits are subject to damage from electrostatic discharge (ESD). Because of this, it has been the practice to ship circuit boards in conductive packages. In order to prevent inadvertent opening of a conductive box containing an electronic circuit board, the box 10 (Figs. 1 and 2) locks when the top lid 11 is closed. The circuit board nests in a cavity 15 situated between anti-static foam elements 16 and 17. A flexible latch 20 is attached to the top cover 11 or integral therewith and is positioned to cooperate with a cam 25 fixed to a wall 13.

The interior latch 20 slides on cam 25 when the box is closed and then snaps into the locked position to prevent the inadvertent opening of the box. In order to open the box, latch 20 must be moved laterally so as to unhook from cam 25. This is accomplished by inserting a grounded electrical connector into a hole 14 to push the latch 20 laterally to allow latch 20 to move past cam 25 as top cover ll is raised to open the box 10. By this arrangement, any electrostatic charge is conducted to ground, thereby preventing damage to the circuit board.
