ABSTRACT:
An effective connector mechanism is described which allows modules to be easily and reliably connected and disconnected. This connector mechanism includes a coordinated arrangement of guide plates featuring mating guide rails and U-shaped channels along with matched sets of tapered pins with tapered slots as well as a spring biased latching mechanism. When mated together, the rails, U-shaped channels, pins and slots lock the modules into engagement in every direction except the forward direction. To prevent forward disengagement, a spring biased latching assembly is provided. This latching assembly features two symmetrically operating latch handles which are each pivotally connected to a T-shaped pawl. When the latch handle is open, the T-shaped pawl rests at the bottom of a ramped runner cut into the walls one module's U-shaped guide channel. As the guide rails from the other module are slid along this U-shaped guide channel, a slot formed in the guide rail of the first module becomes aligned with the ramped runner. At this point, by closing the latch handles, the T-shaped pawl is caused to ride up the ramped runner and into the upper module rail slot in a way which locks the two modules into proper alignment and prevents the upper module from sliding out of engagement through a forward movement. Quick release fasteners are provided at the end of each latch handle to allow the latch handles to be locked into a closed position after the modules are connected.
