DEFINITION

Classification: 439/635

Relative movement of insulating parts alters contact pressure:

(under subclass 634) Coupling part wherein at least two of the segments or sections of insulation are so mounted to one another as to enable movement of one segment or section relative to the other in response to the printed circuit board being inserted into or withdrawn from the channel-like aperture or cavity, and wherein each of the contacts has at least a portion thereof movable in response to the movement of the one insulating segment or section, so that, whenever a printed circuit board is either inserted into or withdrawn from the aperture or cavity, the edge portion of the printed circuit board engages and moves the movably mounted segment or section which then moves the movable portion of the contacts to alter the pressure that they apply to the counter-contacts of the printed circuit board.
