Abstract: A metallic sliding slot structure for an electrical connector, which includes a base in which the slot structure formed by folding and pressing a metallic plate is positioned. The slot structure includes a bottom plate, an inner track plate disposed above the bottom plate, an outer track plate having an opening for enclosing the inner track plate, and at least one one-way block formed by pressing the bottom plate. The inner track plate has one end formed with a tip and the other end formed into an M-like shape to form a concave first positioning point. A one-way circulation path is formed between the inner and outer track plates. A second positioning point corresponding to the tip is defined in the opening of the outer track plate. The path goes from the second positioning point to the first positioning point and then back to the second positioning point.

Abstract: An electrical connector includes a housing that receives an electrical contact. The housing includes a stop element. A terminal position assurance (TPA) member is loaded on the housing. The TPA member is moveable between a staged position and a final position. The stop element engages the TPA member in the staged position to prevent advancement of the TPA member from the staged position to the final position until a contact is fully loaded in the housing.
