The process of mating connectors can result in contact damage due to uneven mating conditions. Connectors mounted on flexible cables have added risk due to the additional hardware and grasping constraints. This design provides assistance in exerting hand-applied load for connector insertion while distributing the load at the four corners of the connector housing. Load applied at these four points enhances load distribution to the entire housing and, therefore, to the entire array of connector contacts, preventing the "rocking" action than can occur with center-load application which tends to lead to damage of the contact pins and mating receptacle contact leads.

    Electrical connectors serve as paths for current in both signal and power applications, connecting between two electrical/mechanical subsystems. Many connectors have large arrays of contact pins for which each must be inserted within a positional x/y tolerance into the receiving receptacle contact(s) in order to be fully seated without damage or disturbance to the combined mated contact geometries and fit. Achieving this requires a degree of uniform load force just sufficient to overcome the contact interface friction at its maximum. Typically, these are inserted by hand which results in less than optimum alignment and force distribution which can result in bent pins and damage to the plastic housing. This is due partly from the contact point limits to what the human hand can achieve; i.e, multi-finger or thumb-index finger grasping techniques. Contact points that are both not equidistant from each other nor evenly balanced on a connectors housing plane are likely to exert unbalanced loading for both amount of force and direction during insertion. This problem can be solved by providing a means to uniformly distribute the applied load across a connectors back plane during the final insertion step following course alignment of the mechanical guidance features.
