Abstract

In an embodiment, a clamping mechanism includes a connection comprising a bridge piece that supports a flex circuit connection to the photodiodes of the detector module. A carrier piece is guided in slots formed by the bridge piece. An interposer is positioned in parallel to the diodes and attached to the carrier piece. A cam acts upon the carrier piece provides clamping force to the interposer. An actuator shaft connects the carrier piece to the bridge piece and imparts rotational motion to the cam. A flex circuit is attached to the carrier piece and is positioned directly below the interposer.

A CLAMPING MECHANISM FOR HIGH DENSITY ELECTRICAL CONNECTION

FIELD OF THE INVENTION

[0001]               This invention relates generally to clamping mechanisms, and more particularly to, a clamping mechanism for high-density electrical connection with limited access.

BACKGROUND OF THE INVENTION

[0002]              For applications where a high-density electrical connection is required it is common to utilize ZIF (zero insertion force) type connectors.  These connectors require a uniform clamping force of approximately 40g per contact to maintain continuity between the electrical conductors of the connector and the pads of the circuit board and/or flex circuit being connected.  For applications such as the connection of the photodiodes of a CT detector module, the access to and space available for this clamping mechanism is limited.  A mechanism is therefore required which provides the required clamping force and can be actuated easily while consuming a minimum amount of space.

BRIEF DESCRIPTION OF THE DRAWINGS

[0003]                 FIG. 1 shows a perspective view of the clamping mechanism according to one embodiment of this invention.

DETAILED DESCRIPTION OF THE INVENTION

[0004]                Various embodiments of this invention provide a clamping mechanism for high-density electrical connection with limited access, especially for connection of photodiodes in a CT detector module.

[0005]             For example, in a co-ordinate system wherein the X direction is the width of the connector, the Z direction is the length of the connector and the Y direction is the depth of the connector, the corresponding co-ordinate system in a CT detector is represented along X direction by the width of a detector module, the Y direction is the direction that the primary x-rays travel and the Z direction is the width of the detector.

[0006]               FIG. 1 shows an embodiment of a clamping mechanism according this invention.  The connection comprises a bridge piece that supports a flex circuit connection to the photodiodes of the detector module.  A carrier piece is guided in slots formed by the bridge piece.   An interposer is positioned in parallel to the diodes and attached to the carrier piece.  A cam acts upon the carrier piece provides clamping force to the interposer.  An actuator shaft connects the carrier piece to the bridge piece and imparts rotational motion...
