Self-adjusting shelf mounted interconnect for a digital display

摘要

A self-adjusting shelf mounted interconnect is disclosed including a bus connector having a series of electrical contacts to engage respective conductive strips of a first electrical bus that runs along a shelf carrying gondola. The self-adjusting interconnect is mounted below a shelf so that when the shelf is removably attached to the gondola, the contacts of the bus connector are automatically mated to the conductive strips of the electrical bus, whereby information transmitted from a remote computer to the first electrical bus can be transmitted to a second electrical bus that runs along the front of the shelf and to a particular one of a plurality of electronic price tag modules that are coupled to the second electrical bus to receive and display the information transmitted from the remote computer. The bus connector is adapted to rotate in response to a pushing force applied thereto when the shelf is connected to the gondola so as to maintain the electrical contacts of the bus connector in constant facing alignment with the conductive strips of the first electrical bus.
