FIELD: electromechanical detachable connections, applicable for connection of electric service lines of a flight vehicle to a ground complex. ^ SUBSTANCE: the unit of electric connectors has a board and contact-break cards fastened by a lock, having electric connectors with engageable components, lock defixing mechanism, cover, pushers engageable with the board card and provided with casings located on the contact-break card, sealing overlapping the intercard cavity and guide pins installed in one of the cards. The unit of electric connectors is provided with a check valve, bushes and adapters. The lock is installed on the contact-break card and hermetically sealed relative to the intercard cavity made for delivery of neutral gas. The lock defixing mechanism is installed on the board card and provided with a damper. The cover is fastened to the contact-break card with formation of a sealed space and seizing the lock, outer connections to the contact-break card of the electric connectors and pusher casings communicating by the inner cavities of the mentioned casings with the intercard cavity and the sealed space of the cover and arranged uniformly in the circumference with the center in the lock axis to the zone of engagement of the components of the electric connectors. The check valve is installed on the contact-break card and communicates with the sealed space of the cover and environment. The sealing of the intercard cavity is made for loss of sealing of the latter after the engagement of the electric connector components is discontinued. The bushes and adapters are made with inner eccentric holes. The guide pins are engageable with the inner eccentric holes of the bushes installed in the inner eccentric holes of the adapters positioned in the card fastened to the card having guide pins, and the bushes and adapters are positioned in the mentioned card for rotation and subsequent fixing. ^ EFFECT: enhanced reliability of the construction. ^ 6 dwg |
