    • In certain embodiments, a PCA connector has a polyethylene body, wherein the polyethylene is durable, corrosion resistant, and exhibits excellent strength over a large range of temperature and moisture conditions. The polyethylene 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 polyethylene 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.
    • 在某些实施方案中,PCA连接器具有聚乙烯体,其中聚乙烯具有耐久性,耐腐蚀性,并且在大范围的温度和湿度条件下表现出优异的强度。 聚乙烯体可以被描述为具有整体特征的单一结构,例如轴承部分,闩锁壳体部分,闩锁引导部分等。 因此,通过身体的一体式设计,部件的数量显着减少。 此外,PCA连接器可以包括被配置为将PCA连接器固定到飞行器的闭锁机构。 例如,闩锁机构可以包括一对杠杆,其与聚乙烯主体的相对侧上的一对闩锁接合。 在一些实施例中,杠杆可以相对于彼此沿相反方向旋转,以使得闩锁沿相同的方向(例如轴向)移动。 而且,闩锁机构的一些实施例分别包括杠杆和闩锁之间的凸轮。
