A FEMALE TERMINAL FOR RAPID-FIT CONNECTIONS

摘要

A female terminal for rapid-fit connections comprises a substantially tubular first body (7) exhibiting a main axis (X-X); a substantially tubular second body (19) coaxial and internal of the first body (7) and axially mobile with respect to the first body (7); a plurality of coupling bail bearings (21) operatively active at a first end (2) of the female terminal (1) able to accommodate a male terminal (100) provided with an annular cavity (109), in which the coupling ball bearings (21) are radially mobile such as to engage in the annular cavity (109) and axially block the male terminal (100); an obturator (32) mounted internally of the second body (19) and axialiy mobile between a closed position and an open position of an axial conduit (4). The female terminal (1) further comprises a guide element (35) of the obturator (32) mounted in the second body (19) and comprising a plurality of peripheral appendages (39) developing substantially parallel to the main axis (X- X), radially elastic and exhibiting terminal engaging ends (41). A radially interna! surface of the second body (19) exhibits a plurality of main housings (27a) able to accommodate the terminal engaging ends (41) and prevent any relative axial movement between the guide element (35) and the second body (19). A third substantially tubular body (46) is mounted coaxially and externally of the first body (7) and is axially mobile with respect to the first body (7). The first body (7) and the third body (46) delimit an annular chamber (51 ) in fluid communication with a second end (3) of the female terminal (1), so that a fluid pressure exerted in the annular chamber (51) pushes the first body (7) towards the first end (2) of the female terminal (1).
