Abstract
Abstract An automatic lock checking device for a wire harness connector having short-circuiting female and male terminals for checking for incomplete locking thereof, including a diagnostic resistance-containing circuit connected parallel with a circuit containing a sensor and having the positive and negative sides thereof connected through conducting terminals of the connector to a load or an electronic control unit adapted to process input signals from the sensor. The automatic lock checking device includes at least a pair of short-circuiting terminals connected in series in the diagnostic resistance circuit and arranged to be short-circuited when the connector is completely locked.

Claim 1
Independent Claim
173 words
An automatic lock checking device for a wire harness connector having first and second connector bodies, the lock checking device comprising: a connector lock sensor circuit including a diagnostic resistance-containing circuit connected parallel with a circuit containing a sensor and having positive and negative sides connected through terminals to a load and an electronic control unit adapted to process input signals from said sensor; a first pair of terminals mounted in the first connector body and short-circuited internally of said first connector body for providing electrical connection between each of said first pair of terminals; and a second pair of terminals mounted in the second connector body, said second pair of terminals being connected with said lock sensor circuit and formed for electrical connection with said first pair of terminals upon complete insertion of one of said connector bodies into the other connector body to automatically actuate said lock sensor circuit upon electrical connection with said first pair of terminals and thereby automatically indicate that said first and second connector bodies are connected.
