Abstract: A connector for electrically connecting a first conductor on a top surface of a first substrate with a second conductor on a top surface of a second substrate, when the second substrate is positioned beneath the first substrate, the connector includes an electrically conductive clip having a first prong and a second prong, with at least a portion each of the first and second prongs positionable at the top and bottom surfaces of the first substrate respectively, such that the first and second prongs provide a clipping force upon the first substrate to engage the first substrate with the clip. The connector further includes a first electrically conductive contact affixed to the first prong of the clip and is for contacting the first conductor when the clip engages the first substrate. An electrically conductive third prong is connected and extends from the clip, and includes a third electrically conductive contact affixed to the third prong for contacting the second conductor.

Abstract: The power cap includes a power supply positioned between a cover and a base. The cover is provided with clips to permit the attachment and detachment of the cover to the power supply and the base. The base is provided with surface mounted NRTC or NVSRAM chips and electrical contacts. The power supply is provided with a crystal oscillator and a battery for controlling the operation of the NRTC or NVSRAM chips, and spring contacts for maintaining the electrical connection between the base and the power supply.
