It is aimed to provide a shielded connector capable of improving heat dissipation performance while suppressing enlargement. A shielded connector 10 includes a housing 11, a shield shell 12 for covering the housing 11 from outside, a connection terminal 14 to be accommodated into the housing 11 and electrically connected to a mating device, and an inner conductive member 13 for electrically connecting the connection terminal 14 and a wire W. High radiation portions 51 having at least a higher radiation rate than a core W1 of the wire W are provided on at least some of a surface 11a of the housing 11, a surface 12a of the shield shell 12, a surface 14a of the connection terminal 14 and a surface 13a of the inner conductive member 13.

An ROV, diver, or stab, wet mateable connector plug front end housing includes a housing front section; a locator mount section; and a seal section axially in series with one another. The housing front section includes a plug coarse alignment feature on an outer surface of the housing front section, adjacent to a front surface of the housing front section and radially outward of a central axis of the housing. There is a circumferential groove on the outer surface of the housing front section, axially displaced from and rearward of the coarse alignment feature, the groove being adapted to receive a latch of a wet-mateable connector receptacle front end housing. The plug coarse alignment feature includes a bullnose feature. A plug fine alignment feature is formed in the outer surface of the housing front section, aligned with and located radially outward of the central axis of the housing.

A dry mate cable connection includes a data cable. The data cable includes a plurality of electrical conductors and at least one electrically insulating outer layer surrounding each data conductor, whereby the data conductors are electrically insulated from one another. The cable includes a termination end. The outer layer of each conductor is physically in contact with an outer layer of an adjacent conductor, except at the termination end. The plurality of electrical conductors at the termination end are physically separated from one another by a single electrically insulating overmoulded cable termination housing. The housing is in contact with at least part of the electrically insulating layers of each of the electrical conductors.
