Electric connector with false connection preventing mechanism and method of connecting thereof

摘要

A pair of connector elements, one connector element having a locking arm, the other connector element having a hood for receiving the one connector element and a locking protrusion provided within the hood are locked in engagement of the locking arm with the locking protrusion when they are completely coupled with each other. When the connector elements are not used or before they are coupled with each other, a body for preventing the one connector element from being fit into the other connector element is inserted in the hood of the other connector element. The body has a locking arm to be engaged with the locking protrusion and a locking portion into which a dedicated jig for pulling out the body from the hood is to be inserted. Thus, in electrical wiring for e.g. an air bag for motor vehicles, it is prevented that when the pair of connector elements are to be coupled with each other, they are connected with a false current flowing through the one connector element and explosion happens in an inflator.
