A spring-to-spring engagement of a kick-out spring and a secondary spring is disposed intermediate a structure supporting an electrical connector and an insertable and latchable electronic module or the like to enhance the disconnection and ejection of the module from the connector to which the module is connected. The spring-to-spring engagement insures both that adequate spring force is stored upon insertion and connection of the module and that disconnection and ejection forces are applied to the module. The forces are applied over a sufficient distance to fully displace the module from its latched position to its position of disconnection from the connectors and still provide spring force travel of the module to eject at least partially the module from the receiver or port into which the module was inserted and connected. A side benefit of the arrangement is that a high force is exerted on the module once it is unlatched for removal, and this high force will displace the module adequately to insure that the latch of the module does not relatch and to prevent removal of the module.

A plug which has a plugging portion and a stem extending therefrom is formed of an elastomeric material in order to deform to create a wiping engagement and a seal with the walls of a receiving cavity. The stem and plugging portion include both cavities for receiving alignment pins in the device being plugged and a manually engageable portion on a distal end of the stem for removing the plug from the sealed cavity, such as within an optical subassembly module. The side edges of the plugging member conform to the cavity cross-section to enhance the sealing yet do not unduly deform the member. The sealing member is formed with one or more standoffs to engage an end face of the cavity, assuring no contact between the optical elements and the plug. The edges of the plug deform upon insertion to create the seal and form a wiping engagement with the cavity interior.
