A clamping device for mounting a base module on a DIN rail is disclosed. The clamping device includes a clamp base, actuator screws, push plates, clamping hooks, and springs. The clamp base is having a planar portion and side walls. The side walls of the clamp base is provided with serrations that indent into DIN rail flange. Further, the planar portion is provided with an aperture for affixing the clamp base to the base module. The pair of actuator screws rotate and pass through the planar portion of the clamp base for facilitating movement thereof with respect to the clamp base. Each push plate is secured to a corresponding actuator screw and is adapted to be either in lifted or seated configuration based on movement of the actuator screw. Each clamping hook includes a first end supported by corresponding push plate and second end movable between engaged disengaged configuration. |

1. A clamping device affixed to a base module for mounting the base module on a DIN rail, the clamping device comprising:
a clamp base having a planar portion and a pair of side walls upstanding from said planar portion for orthogonally supporting the co-planar flanges of the DIN rail, the side walls of the clamp base including serrations that indent into DIN rail flange for facilitating electrical contact, the planar portion provided with an aperture for affixing the clamp base to the base module; a pair of actuator screws adapted to rotate and pass through the planar portion of the clamp base, each actuator screw adapted to move inward and outward with respect to the clamp base; a pair of push plates, wherein each of the push plates includes projections that fit into grooves located on opposite side walls of said clamp base, each of the push plates secured to a corresponding actuator screw and adapted to be either in a lifted configuration or a seated configuration based on movement of the actuator screw; a pair of clamping hooks hingeably supported between the side walls of the clamp base, wherein each clamping hook includes a first end supported by corresponding push plate and a second end with gripping jaws, the second end of the clamping hook adapted to move between an engaged configuration in which the second end is engaging with either of the co-planar flanges of the DIN rail for facilitating clamping of the DIN rail and a disengaged configuration in which the second end of the clamping hook is adapted to disengage from either of the co-planar flanges of the DIN rail; and a pair of springs, wherein each spring is supported on a spring pin disposed between the side walls of the clamp base, each spring is adapted to urge a corresponding clamping hook to a disengaged/open configuration when a corresponding push plate is in a seated configuration. |
