ABSTRACT:
TECHNICAL FIELD
The present invention relates to an electrical connector assembly, and more particularly to an electrical connector assembly having a pre-aligning terminal blade stabilizer.
BACKGROUND OF THE INVENTION
A multi-bladed electrical connector has a male connector portion which firmly supports a series of male terminals that are locked within respective terminal cavities of the male connector portion. A female connector portion of the electrical connector mates typically via a snap locking feature to the male connector portion. When mating, the pins are received by respective pin receptacles of the female connector portion to form the electrical connections.
A blade or pin of each terminal projects forward from each terminal cavity and into a common blind bore or chamber defined by a forward projecting circumferential encasement or shroud of the male connector portion. The female connector portion of the electrical connector houses the series of pin receptacles which communicate through a leading end of the female connector portion. For a reliable electrical connection, each pin receptacle must align with its respective pin of the terminal of the male connector portion. When the electrical connector is mated, the leading end portion of the female connector portion fits into the chamber of the male connector portion and is thus guided by the circumferential encasement.
Unfortunately, during the manufacturing phase and/or handling of a wire harness, which is engaged to the male connector portion of the electrical connector, the exposed protruding pins of the terminals can potentially be knocked or bent, or debris may enter the chamber of the male connector portion which results in the inability of the terminals to connected electronically within the pin receptacles of the female connector portions. Moreover, the manufacturing dimensional variances between the terminals and the male connector portion housing cause the terminals to pivot slightly within the housing and the distal ends of the pins to become misaligned with the receptacles.
SUMMARY OF THE INVENTION
An electrical connector assembly has a male connector which mates to a female connector thereby electrically engaging male terminal blades, locked to a male connector body, to female terminals locked to a female connector body. The blade of each male terminal extends into a blind bore defined by a shroud of the male connector body. Prior to mating of the electrical connector assembly, a self-aligning blade stabilizer is snap fitted into a blade alignment position with the male connector via a lock arm which prevents withdrawal of the stabilizer from the male connector and a flex arm which restricts insertion of the stabilizer into the male connector. When the stabilizer is in the blade alignment position, the tips of the blades are disposed within respective apertures of the stabilizer and aligned to their respective female terminals. Moreover, the terminal blades are protected from being inadvertently knocked and bent which would cause blade misalignment and hinder electrical continuity of the mated assembly. Furthermore, the stabilizer prevents entry of debris into the blind bore of the male connector which would hinder or prevent full mating of the electrical connector. During mating of the electrical connector assembly, the stabilizer is pushed out of the blade alignment position and into a seated position as the blades travel through the apertures and into the female terminals of the female connector.
An advantage of the present invention is the prevention of accidental mis-alignment or bending of the protruding blades of the terminals of the male connector portion. Another advantage of the present invention is the elimination of foreign article or debris collection within the chamber of the male connector portion which could prevent full mating of the electrical connector. Yet another advantage of the invention is the incorporation of a blade stabilizer having a blade alignment position without having to re-design the male or female connector of the electrical connector assembly.
