Systems and devices for installing an evacuation slide actuation cable in a connection box assembly of an emergency evacuation slide and overwing door actuation system interface

A system for assuring connection of an evacuation slide actuation cable to an evacuation slide inflation system, the system comprising:

• an electrical connector coupled to the evacuation slide inflation system;
• and
• a connection box assembly comprising:
• a connection box;
• a connection box Rd coupled to the connection box and configured to slide between an open position and a closed position;
• a connection box slider disposed within the connection box and positioned to receive a first cable end of the evacuation slide actuation cable when the connection box lid is in the open position, wherein the connection box lid in the closed position closes the connection box to retain and seal the connection box slider and the first cable end inside the connection box assembly;
• and
• an electrical connector blocker coupled to the connection box lid for preventing electrical connection to the electrical connector prior to retaining and sealing the first cable end and the connection box slider in the connection box assembly.

An installation assurance method comprising:

• coupling an electrical connector blocker to a connection box lid of a connection box assembly comprising:
• the electrical connector blocker;
• a connection box;
• the connection box lid coupled to the connection box and configured to slide between an open position and a closed position;
• and
• a connection box slider disposed within the connection box;
• sliding the connection box lid to the open position wherein the electrical connector blocker prevents electrical connection to an electrical connector coupled to an evacuation slide inflation system;
• inserting a first cable end of the evacuation slide actuation cable into the connection box and the connection box slider;
• and
• sliding the connection box lid to the closed position thereby closing the connection box to retain and seal the connection box slider and the first cable end inside the connection box assembly and permitting electrical connection to the electrical connector only after the connection box slider and the first cable end are retained and sealed inside the connection box assembly.
