Patent attributes
A terminal position assurance device (TPA) generally of a “C-shape” design which fits into a housing for an electrical connector, has two arms including a side portion and a ledge portion, and a back portion. The TPA arms flex such that housing breakage is limited. The inward facing surface of each ledge portion has a narrowly tapered shape. The corresponding housing used has a C-shape opening similarly shaped to the TPA. The TPA has stops that engage the housing such that the TPA device can be inserted into the housing at preset and full-lock positions and will not eject out. At a full-lock position, the TPA fully resides in the housing opening completely. The TPA also has associated pads that reduce associated noise with the housing when it is in service.
