Definitions

  • the invention relates to a keying system for permitting mating together of connector assemblies.
  • a suitable keying system for mating pairs of the connector assemblies will permit mating together of the connector assemblies in corresponding predeterminate positions with respect to one another.
  • the suitable keying system further will produce a variety of keying combinations from which a particular keying combination is selected and then applied to the pair of connector assemblies.
  • the suitable keying system will prevent mating together of connector assemblies not having the same keying combination.
  • a keying system disclosed in U.S. patent 4,376,565 includes break away portions providing slots in a first connector assembly and opposing grooves in a second connector assembly. A key is added to either one or the other of an opposing slot or groove to provide a selected keying combination.
  • the prior keying system requires assembly of separate keys to corresponding connector assemblies. A disadvantage may arise that the separate keys are absent at a time when the connector assemblies are ready for installation as a mated pair. Accordingly, a need exists for a keying system constructed directly on corresponding connector assemblies for providing a selected keying combination available at a time when the corresponding connector assemblies are intended as a mated pair.
  • An aspect of the invention is directed to an improved keying system formed during manufacture directly on corresponding connector assemblies and providing a variety of keying combinations from which a keying combination is selected.
  • Another aspect of the invention resides in a keying system for connector assemblies in which one of the connector assemblies has opposite sides and is provided with removable individual keying elements arranged in a first pattern on one side and a second pattern on the other side, and the other of the connector assemblies has opposite sides and is provided with removable individual keying elements arranged in a repeated first pattern and a repeated second pattern on each of the opposite sides.
  • the sides are duplicates of each other for convenient manufacture of a part of single design.
  • Figure 1 is a fragmentary perspective view of a keying system directly on corresponding connector assemblies, with conductive grounding clips for the connector assemblies, and with parts illustrated in exploded configuration.
  • Figure 2 is an elevation view of an interior of a first side of a connector assembly having individual keying elements.
  • Figure 3 is an elevation view of an exterior of a second side of a connector assembly having individual keying elements.

  • Figure 8 is a fragmentary perspective view of the connector assemblies shown in Figure 1 and mated together without illustration of the conductive clips.
  • FIG 9 is a fragmentary enlarged perspective view of a portion of a connector assembly shown in Figure 1.
