Electrical connector assembly with unlocking device for the unlocking process

A connector assembly (1) comprising:

• a. a first connector portion (2) with a first housing (6) with a circumferential inner locking shoulder (10) at a first end (8) of the first housing (6);
• b. a second connector portion (3) interconnectable with the first connector portion (2), having a second housing (7) with a circumferential outer groove (9);
• c. a radially deformable locking ring (4) arranged in the circumferential outer groove (9) of the second connector portion (3), the radially deformable locking ring (4) including
• i. a circumferential outer locking shoulder (11), behind which the inner locking shoulder (10) of the first connector portion (2) is locked in a connected state of the first and the second connector portion (2, 3)
• ii. an unlocking surface (12) that is circumferentially accessible from an outer vicinity of the unlocking surface (12) in the connected state, wherein the locking ring (4) is adapted to deform in a radial direction upon application of a radial force, and wherein the outer locking shoulder (11) is located in a direction of connection behind the unlocking surface (12) on the locking ring (4);
• and
• iii. an axial slot (13), wherein the axial slot (13) extends over the outer locking shoulder (11) and the unlocking surface (12).
