Digital verification of battery cable connection to power distribution module

摘要

A digital verification system and method is described for verifying that the terminal connector assembly of an automobile's battery cable is properly connected to the connector assembly of a power distribution module (PDM). The terminal connector assembly is provided with an integrated CPA assembly having an engagement member, such as an elongated appendage. The PDM connector assembly is provided with a shorting bar that contacts a bus bar so as to cause a short circuit to occur when current is supplied to the PDM connector assembly through the battery's terminal connector assembly. A sense lead in contact with the shorting bar sends a response signal through a printed circuit board to a microprocessor indicating that electrical power is flowing though the short circuit. The CPA assembly can only be engaged when the terminal connector assembly is fully mated to the PDM connector assembly. When the CPA assembly is engaged, the engagement member simultaneously contacts the shorting bar and causes the short circuit to be interrupted. The sense lead then sends a response signal to the microprocessor indicating that no electrical power is flowing through the circuit. In this manner, a technician can be assured that a proper connection has been established between the terminal connector assembly and the PDM connector assembly.
