PRE-LOADED CONNECTING ELEMENT Russian patent published in 2016 - IPC E21B33/38 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to wellhead equipment, particularly to means for emergency disconnection between components connected to underwater well. Disclosed is connector (100) containing retainers (107) distributed along peripheral part of connector (100) on its connecting side. At that, said retainers (107) pass, in fact, in axial direction and can be engaged with connector (100) with its first end and engaged with connecting piece (201) opposite locking end equipped with fixing profile (109). At that, in fact, radial fixing movement of fixing end is provided by axial movement of actuating coupling (113) sliding relative to actuating surface (107b) holder (107), and retainers (107) can turn, in fact, radially around engagement section with connector (100) for inlet and outlet of locking position. Besides, connector (100) additionally contains guide plates (111), located between retainers (107) in area of their fixing ends and having protective faces (111a) passing inside in radial direction more than fixing profile (109) fixtures (107), when latter are turned outside position.

EFFECT: providing reliable connection under varying load due to prevention of play between components.
