  • Keyed electrical connector with main and auxiliary electrical contacts
    Patent number: 4990099
    Abstract: A hermaphroditic or "genderless" electrical connector having a main housing and an auxiliary housing. The main housing contains primary electrical contacts while the auxiliary housing provides mechanical keying and, preferably, contains auxiliary electrical contacts. The auxiliary housing can be positioned within the main housing in a plurality of orientations to provide mechanical keying when the electrical connector is telescopically engaged with a duplicate electrical connector.

  • Electrical device with bi-level battery state-of-charge indicator
    Patent number: 4248942
    Abstract: An electrical device for use with electric storage batteries has a bi-level battery state-of-charge indicator incorporated therein. The electrical device is shown as a battery cable connector and a battery cable clamp. The built-in indicator provides an indication of the battery state-of-charge when the battery reads a preselected state-of-charge and continues to provide such an indication until the battery has been discharged to a preselected state. The indicator utilizes a light emitting diode to monitor the battery state-of-charge through the use of bi-level voltage comparator circuit.
