Modular clamping system

An apparatus for mounting a device on a substrate having a hole, the apparatus comprising:

• a housing configured to couple to the device;
• a clamping assembly moveably coupled to the housing such that translational and rotational movement of the clamping assembly relative to the housing is guided by the housing, the clamping assembly further comprising a clamping arm coupled to an expandable link, the clamping arm including a clamping surface;
• a link arm having a first end and a second end, wherein the first end is pivotally coupled to the expandable link and the second end is pivotally coupled to the housing at a first axis;
• and
• a clamping lever having a first end and a second end, wherein the second end is pivotally coupled to the housing at a second axis parallel to the first axis and wherein the second end of the link arm and the second end of the clamping lever are rotationally coupled, wherein the clamping lever is rotatable about the second axis between an open position and a closed position, whereby the clamping arm is moved between an unclamped position and a clamped position as a result of the clamping lever being rotated from the open position to the closed position, wherein in the unclamped position the clamping arm is located entirely within a perimeter of the hole when the apparatus is inserted in the hole, and wherein rotating the clamping lever to the closed position causes the clamping arm to be moved to the clamped position such that the clamping arm is located at least partially outside of the perimeter of the hole and a portion of the substrate is clamped between a flange of the housing and the clamping arm.
