Abstract
A keyed high voltage connector of this invention is adapted to prevent connection to a standard connector having a standard shaped shell and which retains a standard contact mounting insert with a standard length contact supporting portion defined by end walls spaced a standard length by contact supporting walls. Typically, the standard connector may be of a low voltage type whereas the keyed connector carries high voltages which must not be directly connected or accidentally arced over to a seemingly mateable low voltage connector. Alternatively, the standard connector may carry a high voltage and the keyed connector a low voltage. The keyed connector of this invention uses the standard shaped shell and has a contact mounting insert with a contact supporting portion retained within the shell. At ends of the contact supporting portion keying portions are provided which begin at points spaced less than ends of the standard length contact supporting portion and terminate at points longer than ends of the standard length contact supporting portion. These keying portions may be provided as slots of reduced width or extended portions of reduced width. The keying portions are also raised to project above the level of a mating insertion end of the contact supporting portion to prevent arc-over of high voltages between a standard connector and a keyed connector. Also, the shell used with the keyed connector may be externally keyed to provide visual identification and to prevent mating with a standard connector.
