CONNECTION METHOD OF CONNECTING SECTION OF HOSE FOR LIQUID OR GASEOUS MEDIA WITH PLUG CONNECTOR Russian patent published in 2019 - IPC F16L33/213 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to connection of connecting section (33) of hose (3) with plug connector (4). Plug connector (4) includes connector body (6), which has annular space (22). At the first step of the method, connecting section (33) of hose (3) is inserted from side (25) of receiving the hose of body (6) of the connector into circular space (22) of plug-in connector (4) and is positioned. At second step of method pressing tool (50) deforms first shell section (12) of body (6) of connector. Second shell section (15) has, at front edge (38) of hose intake side (25), constriction (39), as a result of which connecting section (33) of hose (3) during the pressing process, at least in the area of annular space (22) located at a distance from front edge (38), is freely deformed in the direction of the second shell section (15), before connecting section (33) of hose (3) comes into contact with second shell section (15).

EFFECT: invention provides improved connection between hose and plug connector due to control of degree of pressing.
