Abstract: In certain embodiments, a PCA connector has a nylon body, wherein the nylon is durable, corrosion resistant, and exhibits excellent strength over a large range of temperature and moisture conditions. The nylon body may be described as a single structure with integral features, such as a bearing portion, a latch housing portion, a latch guide portion, and so forth. Thus, the number of parts is significantly reduced by the one-piece design of the body. In addition, the PCA connector may include a latching mechanism configured to secure the PCA connector to an aircraft. For example, the latching mechanism may include a pair of levers, which engage a pair of latches on opposite sides of the nylon body. In some embodiments, the levers may be rotated in opposite directions relative to one another to impart movement of the latches in the same direction, e.g., an axial direction. Also, some embodiments of the latching mechanism include a cam between the levers and the latches, respectively.

Abstract: A power delivery system for parked aircraft includes protective rings on the power cords. These protective rings protect the power cord jackets from wear and facilitate movement of the power cords across the ground. The rings may be configured for securement to the cable so as to compress the insulative jacket of the cable somewhat, thereby firmly maintaining the rings in place on the cable. The rings may be formed of two identical elements that are joined to envelope the cable. The rings may accommodate both round insulated cable, as well as bundled cable.
