Automatic interconnection assembly, notably for electrical connection to a pack comprising a plurality of missile-launcher tubes

Claim 1

An automatic interconnection assembly, designed to provide for the electrical connection of a frame to a pack supported on a body by the plugging in of a connector, comprising: a first connector element supported on said pack and fixedly joined to a first supporting surface; a second connector element capable of being made to approach said first element and then being plugged into it; an external tube fixedly joined to said frame; a control actuator positioned within said external tube and having a movable rod; an intermediate tube, housed in a fixed external tube and movable in axial translation in it, said intermediate tube having, at an end pointed towards said pack, a second supporting surface homologous with said first supporting surface; an internal tube, housed in the intermediate tube and movable in translation, said internal tube having a first end pointed towards said pack and bearing said second connector element and a second end connected to said rod of the control actuator; elastic means of linkage between said internal tube and said intermediate tube to enable the transmission to the intermediate tube, during the approach movement, of the shift communicated to the internal tube by the actuator until said first and second supporting surfaces come into contact, the stretching of the actuator then causing only a shift of the internal tube alone; alignment means formed on said supporting surfaces to axially and transversally align the two connector elements and to orient them angularly with respect to each other, when they are approaching each other, prior to the start of the plug-in operation; means for limiting the travel of the actuator, to detect the total plugging together of the connector elements and to then interrupt the stretching of the actuator; and a flap valve hinged on said body by a shaft and including an opening-control roller which prompts the opening of said flap during the stretching of said intermediate tube.
